Resumo: Atualmente aproximadamente 17 milhões de pessoas morrem por doenças cardiovasculares (DCV). No Brasil durante 2011 ocorreram cerca de 200 mil óbitos por DCV principalmente em decorrência da aterosclerose, classificada como uma doença imuno-inflamatória crônica que causa estreitamento luminal e gera diversas fatalidades como infarto agudo do miocárdio (IAM), acidente vascular encefálico (AVE), doença arterial periférica (DAP), entre outras. A DAP prediz outras DCV e é a principal causa de amputação devido a obstrução das artérias de membros inferiores. Análises histológicas indicam que a ruptura da placa, capa fibrosa do ateroma, erosão da placa e nódulo calcificado geram as principais fatalidades nas DCV. Até o momento não há biomarcadores plasmáticos para uso clínico afim de avaliar a estabilidade e a gravidade das placas ateroscleróticas, esse fato motiva a exploração de componentes envolvidos em doenças imuno-inflamatórias e no metabolismo lipídico tais como oxisteróis e marcadores da síntese e absorção do colesterol (MSAC). Os oxisteróis, principalmente 27-hidroxicolesterol (27-HDC) e 7-ketocolesterol estão envolvidos em mecanismos fisiopatológicos da aterosclerose e desempenham um papel na inflamação, citotoxicidade e necrose, além de funções no metabolismo lipídico. É relatado que os oxisteróis 24S- e 25-hidroxicolesterol (24S- e 25-HDC) estão envolvidos em doenças neurodegenerativas como Alzheimer. Estudos apontam uma causa em comum entre Alzheimer e aterosclerose, ambas são doenças inflamatórias crônicas, assim são necessárias mais investigações desses oxisteróis na doença aterosclerótica. A proteína de transferência de éster de colesterol (CETP) e proteína de transferência de fosfolípides (PLTP), assim como as lipoproteínas, podem mediar a transferência desses lípides. O objetivo desse trabalho foi quantificar concentrações de oxisteróis (24S-, 25-, 27-HDC e 7-ketocolesterol) e marcadores de síntese (desmosterol e latosterol) e absorção (?-sitosterol e campesterol) do colesterol em ateromas e plasma de 10 indivíduos com DAP (grupo DAP) e comparar com artérias sem ateroma de 13 voluntários (grupo CTL). Também relacionar esses esteróis com outros parâmetros como histórico clínico e proteínas de transferência de lípides. Foram realizadas análises clínicas e bioquímicas, classificações histológicas dos ateromas e quantificações de esteróis em artérias e plasma. Para interpretação dos dados obtidos foram usados testes estatísticos de comparação e correlação. Os dois grupos apresentaram uma similaridade nos dados clínicos e bioquímicos, diferenciando apenas em pressão arterial sistólica, atividade da PLTP, glicose e proteína C reativa (PCR), maiores no grupo DAP. A PCR se correlacionou positivamente com 24S-HDC, 25-HDC e 27-HDC plasmáticos. Comparação entre os grupos em relação a concentração de oxisteróis em artérias mostraram o 24S-HDC e o 27-HDC maiores no ateroma do grupo DAP, curiosamente o 25-HDC esteve maior em CTL. Quantificações de oxisteróis em plasma do grupo DAP mostrou um aumento do 25-HDC em relação ao grupo CTL. Não houve diferença significante para os MSAC. Os ateromas classificaram-se em 50% ruptura da placa, 20 % capa fibrosa do ateroma, 10% nódulo calcificado e 10% lesão fibrocálcica. Em conclusão mostramos o acumulo do 24S-HDC em placas de aterosclerose. O 27-HDC assim como outros estudos esteve em maior concentração nos ateromas indicando fortemente sua ação na patogênese dessa doença. Todos os oxisteróis sintetizados enzimaticamente dosados em plasma se correlacionaram positivamente com atividade inflamatória sistêmica, assim como 24S-HDC e 27-HDC em ateromas. Finalmente a atividade da PLTP esteve maior no grupo DAP
Abstract: Currently around 17 million people die from cardiovascular diseases (CVD). In Brazil, durant 2011 nearly 200.000 deaths occur mainly due atherosclerosis, classified as a chronic, immune-inflammatory disease that causes luminal narrowing and generates several outcomes as myocardial infarction, cerebrovascular accidents (stroke), peripheral arterial disease (PAD) and others. DAP predict other CVDs and is the leading cause of amputation due the clogged arteries in inferior members. Histological analysis indicates that plaque rupture, fibrous cap atheroma, plaque erosion and calcified nodules generate major CVD fatalities. So far, no plasma biomarkers for clinical use are available in order to evaluate the stability and extend of atherosclerotic plaques, therefore is necessary the investigation of the components involved in immune-inflammatory diseases and lipids metabolism such as oxysterols and cholesterol synthesis and absorption markers (CSAM). Oxidized sterols or oxysterols, manly 27-hidroxycholesterol and 7-ketocholesterol are involved in pathophysiological mechanisms of atherosclerosis and play a role in inflammation, apoptosis, necrosis and cytotoxicity, in addiction to lipid metabolism. Oxysterols 24S- and 25-hidroxycholesterol are involved with neurodegenerative diseases such Alzheimer¿s and resemble with atherosclerosis development since are chronical inflammatory diseases, for this reason is necessary an investigation of these oxysterols in atherosclerosis is needed. Cholesteryl ester transfer protein (CETP) and phospholipid transfer protein (PLTP) as well as lipoproteins, could mediate the transfer of the oxysterols. The aim of this work was quantified the levels of oxysterols (24S- 25-, 27- hidroxycholesterol and 7-ketocholesterol) and cholesterol synthesis (desmosterol and lathosterol) and absorption markers (?-sitosterol and campesterol) in atheroma and plaques from 10 individuals with PAD (PAD group) and compare with arteries without atheroma of 13 volunteers (CTL group). Also, relate these sterols with other parameters as clinical history, lipid transfer proteins and histological scores. Clinical and biochemical data were collected and sterols were quantified in arteries and plasma by gas chromatography coupled to a mass spectrophotometer (GCMS) and histological atheroma classification were determined. Comparison anlysis were performed using Mann-Whitney and correlations by Spearman¿s test. Both groups were not different regarding clinical and biochemical data, differencing only for systolic blood pressure, alcohol intake, PLTP activity, glucose and CRP, increased in PAD group. CRP was positively correlated with 24S-HDC, 25-HDC e 27-HDC from plasma. The comparisons of oxysterols levels in atheroma showed that 24-HDC and 27-HDC were increased in PAD group; interestingly, the 25-HDC was higher in CTL group. No significant differences were observed for CSAM between groups. The atheroma were classified as 50% plaque rupture, 20% fibrous cap, 10% calcified nodules and 10% of fibrocalcific injury. From the oxysterols from plasma of PAD group, only 25-HDC was increased compared to the CTL group. In conclusion, we demonstrated the accumulation of 24S-HDC in atherosclerotic plaques. The 27-HDC, as well as other studies, present higher levels in atheroma¿s, strongly indicating is role in the disease pathogenesis. All oxysterols measured in plasma were positively correlated with the systemic inflammatory activity. Finally, all atherosclerotic plaques were classified as lesions of advanced extension, according to the histological analysis

Full textAlzheimers disease (AD) and vascular dementia (VaD), especially its subcortical form, are responsible for the majority of dementia cases in the elderly and are not always easily differentiated from a clinical point of view. The aim of this study was to compare the performance of mild VaD and AD patients in a series of brief cognitive tests (Mini-mental State Examination and Neuropsi battery, in order to confirm the diagnosis of dementia; CLOX 1 and 2, category and letter fluency, a delayed recall test of 10 simple figures and the EXIT 25), and to evaluate the potential use of these tests for the differential diagnosis between them. The performance of the VaD group was significantly impaired, in relation to the AD group, in the tests CLOX 2, category verbal fluency and letter verbal fluency, while the AD patients performed significantly worst in the delayed recall test.

Resumo: O presente estudo objetiva avaliar, comparativamente, de modo prospectivo, a utilização do fio de categute cromado e poliglecaprone 25 em sutura vesical em plano único em ratos. Para isto foram selecionadas 60 ratas fêmeas, da raça Wistar, com peso entre 180 à 240 gramas, e com idade variando de 5 a 6 meses. Os animais foram alocados em dois grupos de 30 : grupo I ( controle) , sutura com categute cromado, e II ( experimento) ; com poliglecaprone 25 . Cada grupo foi subdividido em 3 subgrupos conforme o dia da realização do sacrifício : subgrupo I-A e II-A no 4o dia; subgrupo I-B e II-B no 7o dia e subgrupo I-C e II-C no 14o dia. Os animais foram operados no Departamento de Cirurgia Experimental da Fundação Universitária Regional de Blumenau, tendo sido submetidos a ressecção de 1 mm da cúpula vesical, seguido de sutura total da mesma com pontos separados com os fios do estudo. Na analise macroscópica analisou-se a ferida cirúrgica em relação a presença de aderências com estruturas vizinhas, deiscência da sutura , necrose da anastomose e infeção. No estudo histopatológico, realizado com as colorações de Hematoxilina-eosina e Masson foram analisadas as seguintes variáveis : coaptação das túnicas serosa, muscular e mucosa, processo inflamatório agudo, processo inflamatório crônico e tipo do tecido conjuntivo encontrado na cicatrização. Na avaliação das aderências notou-se que estavam presentes em todos os animais e mais intensas no grupo I. Houve um caso de deiscência da sutura no grupo I com óbito do animal no 2o dia pós operatório. Não houve nenhum caso de necrose da sutura ou de infeção. Não houve nenhuma diferença estatística significativa nos parâmetros histopatológicos estudados. Os resultados permitem concluir que : a vesicorrafia realizada com os fios de categute cromado não mostrou diferença quando comparada com o fio de poliglecaprone 25.
Abstract: The present study aims at prospectively comparing the use of cromic catgut suture and polyglecaprone 25 suture in bladder anastomoses in rats. Sixty female Wistar rats weighing between 180 and 240 grams and aging from five to six months were selected. The animals were randomly allocated in two groups of 30 animals: group I (control) - cromic categute suture, group II (experiment) - polyglecaprone 25 suture. The rats were sacrificied after being allocated in three subgroups: subgroups I-A and II-A were sacrificed postoperatively on day seven; subgroups I-B and II-B were sacrificed on the seventh day; and subgroups I-C and II-C were sacrificed on the fourteenth day.The animal were operated in the Experimental Surgey Laboratory of the Blumenau Regional University and were submitted to a resection of 1 mm of the bladder and total anastomoses using the sutures under study. Both groups were analyzed regarding the presence of adhensions to adjacent structures, suture dehiscence, anastomotic necrosis, and infection. In the histophatologic study using the Hematoxilin-eosin and Masson stainning, the following variables were analyzed: coaptation, inflammatory reaction, and type of colagenus tissue. It was observed, through the evaluation of adhensions, that they appeared in all rats, but were more intense in group I. One case of suture dehiscence in group I caused the animals' death. There was not statistically significant difference in all the histologic parameters. The results lead to the following conclusion: bladder sutures with cromic catgut do not differ when compared to sutures with poliglecaprone 25.

Full textAn experiment was conducted with the objective to evaluate the addition of 25-hydroxycholecalciferol (25(OH)D3) with vitamin D3 in diets of broiler breeders hens. The experiment used six hundred and fifty broiler breeders Cobb 500 and was organized in a complete randomized design with four treatments and eight replication of twenty female and two male each. The treatments were constituted of vitamin premix with 2000 and 3400 IU/kg diet of vitamin D3 as the only source of vitamin or 2000 IU D3 plus 35 or 69 μg/ton of 25(OH)D3. The results of these experiment indicated that 25(OH)D3 had no significant effect on the total, hatch and damaged weekly egg production, as well as on the total number and total hatch eggs/bird for the entire experimental period from 32 to 67 weeks. There were no effect of the addition of 25(OH)D3 on the weight egg. The supplementation of 25(OH)D3 resulted in better quality shell evaluated through the specific gravity at 60 weeks of age, independent of the dosage. At 35 week the dose of 3400 IU D3 had better quality when compared with the 2000 IU D3 and 2000 IU D3 +69 μg 25(OH)D3 dosages. No significant difference (P>0,05) was observed for hatchability of fertile eggs at 54, 64 and 67 weeks of broiler breeders. The hatch residue breakout showed less mortality of embryos at third week for treatments from 2000 UI D3 P(<0,03) at 64 week and less mortality of embryos at second week of development from hens with 67 week and supplemented with 2000IU D3 and 2000IU D3+ 69 μg 25(OH)D3. The results indicated that the supplementation of 25- hydroxycholecalciferol with cholecalciferol had similar effects as the diets with vitamin D3 as the only source on the productive performance of broiler breeders hens.

Law in the Hebrew Bible undergoes a paradigm shift: Laws that are restricted to civil society are now regulated by officially religious Laws. This analysis seeks to understand a casuistic Law that addresses the situation of a pregnant woman, because there is the risk of miscarriage if he would hit her by during the fight, as penalty will be imposed the Law of Talion. Through exegetical, historical, theological and social analysis; Beginning with the translation of the Hebrew text, a legal understanding of Exodus 21: 22-25 will be sought from the perspective of the pregnant woman. From the analysis comes a brief understanding of the civil and religious law in today's society of Brazil and the Magisterium of the Catholic Church. In despite of the laws seek to protect the pregnant woman, it is not full protection yet
O direito na Bíblia Hebraica passa por uma mudança paradigmática: Leis que são restritas à sociedade civil passam a ser reguladas a partir de Leis oficialmente religiosas. Nessa análise se busca compreender uma Lei casuística que aborda a situação de uma mulher grávida, pois corre o risco de perder suas crianças caso seja atingida por movimentos consequentes de uma briga de homens, como penalização será imposta a Lei de Talião. Através da análise exegética, histórica, teológica e social; a começar pela tradução do texto em hebraico, buscar-se-á emitir uma compreensão jurídica de Ex 21,22-25 na perspectiva da mulher grávida. A partir das análises chega-se a uma breve compreensão da Lei civil e religiosa na sociedade hodierna do Brasil e do Magistério da Igreja Católica. Se por um lado as Leis buscam proteger a mulher grávida, por outro, essa proteção é ainda fragmentada

Full textObjetivo: Determinar as concentrações séricas de 25-hidroxicolecalciferol (25(OH)D), cálcio sérico total, fósforo sérico, fosfatase alcalina e paratormônio (PTH) em pacientes com artrite idiopática juvenil (AIJ) poliarticular e associá-las com a atividade e duração da doença, com a densidade mineral óssea e com o uso de medicamentos. Método: Por meio de um estudo transversal e controlado, foram avaliados 30 pacientes com AIJ poliarticular, pareados por sexo e idade com 30 controles saudáveis. Realizou-se avaliação clínica, antropométrica e laboratorial nos pacientes e controles e densitometria óssea nos pacientes. Resultados: Dos 30 pacientes incluídos no estudo, 23 (76,7%) eram meninas, 16 (53,3%) não caucasóides e com média de idade de 14 anos (4 a 20 anos). O tempo médio de doença foi 5 anos. Concentrações médias de cálcio sérico total e fosfatase alcalina foram significantemente mais baixas nos pacientes com AIJ comparativamente aos controles (p< 0,0001 e p= 0,001, respectivamente). Em relação a 25(OH)D, PTH e fósforo sérico não se observaram diferenças entre os grupos AIJ e controle. Quanto às concentrações séricas de 25(OH)D, 8 pacientes (26,7%) e 5 controles (16,7%) apresentaram valores compatíveis com deficiência (inferiores a 20 ng/ml) e 14 pacientes (46,7%) e 18 controles (60%) apresentaram valores compatíveis com insuficiência (entre 20–32 ng/ml). Estes valores não se associaram com a atividade de doença, com o uso de medicamentos ou densidade mineral óssea. Conclusão: Observamos elevada frequência de insuficiência e deficiência de 25(OH)D nas amostras estudadas. O comprometimento do metabolismo ósseo enfatiza a importância do acompanhamento evolutivo dos pacientes com AIJ.
Objective: To determine serum concentrations of 25-hydroxycholecalciferol (25(OH)D) and biochemical markers of bone turnover in patients with polyarticular juvenile idiopathic arthritis (JIA) and to associate them with disease activity and duration, with bone mineral density and with use of medications. Methods: In a cross-sectional and controlled study, 30 patients with polyarticular JIA were assessed, compared with 30 age and sex-matched healthy subjects. We evaluated clinical, anthropometric, laboratory parameters and dual-energy x-ray absorptiometry (DEXA). Results: Out of 30 patients included in the study, 23 (76.7%) were girls, 16 (53.3%) no caucasian and the mean age was 14 years old (4 to 20 years). The mean time of disease was 5 years. The mean serum calcium and phosphatase alkaline were significantly lower in patients with JIA compared to controls (p<0.0001 and p=0.001, respectively). There was no difference between the serum concentrations of 25(OH)D, PTH and phosphorus between patients and controls. Based on serum 25(OH)D concentrations, 8 patients (26.7%) and 5 controls (16.7%) were vitamin D deficient (< 20 ng/ml) and 14 patients (46.7%) and 18 controls (60%) were vitamin D insufficient (between 20 and 32 ng/ml). These values were not associated with disease activity, use of medications or bone mineral density. Conclusions: A high frequency of 25(OH)D insufficiency and defficiency was observed in the study population. The involvement of biochemical bone markers emphasizes the importance of the bone metabolism follow-up in patients with JIA.

Full textThe process of communication of the heath team with the mother whose child is under phototherapy is fundamental so that she can calm down and become acquainted with the treatment. The thesis defended in this research is that the communication permeated by the Nursing humanistic care will contribute to the mother of the newborn under phototherapy come to know, understand the treatment and this way be well and be - better. We aimed to analyze the communication with mothers of newborns under phototherapy through the Phenomenological Nursing Process of the Paterson and Zderadâs Humanistic Theory. Qualitative, exploratory and descriptive study, instrumentalized through the mentioned process, in five stages: the preparation of the nurse to come to know; the nurse knows intuitively the other; the nurse knows scientifically the other; the nurse synthesizes in a complementary way the known realities; the internal succession of the nurse starting from many to an only paradoxical. It had as environment a public maternity hospital in Fortaleza-CE. The subjects were 25 mothers taken into the referred institution, whose newborn (NB) children were under phototherapic treatment in the Neonatal Care Unit (NCU) of high, medium risk and/or Shared Accommodation (SA), from January to March/2005. We used as technique the participant observation and the individual interview, in two phases, with the following orienting question âWhat does it mean for you, mother, to witness your child under phototherapy?â In the data analysis of the participant observation we could visualize the interactions mother/newborn/nurse. From the speeches extracted from both phases of the interview the following themes were identified communication, knowledge, care, perception and feelings. From the theme communication, we extracted in the first phase the sub-themes damaged communication with the health team; lack of communication of the health team and communication motherânewborn; and in the second phase, reactions of the mother after effective communication of the nurse. From the theme knowledge, we extracted in the first phase the sub-themes lack of knowledge about phototherapy and search for knowledge about phototherapy and in the second phase, acquired knowledge about phototherapy and comprehension of the phototherapic treatment: a new vision of the mother. From the care theme, we extracted in the first phase the sub-theme the newborn under phototherapy â mothers searching Nursing Care and in the second phase, care-presence: participation of mothers in the care to newborn under phototherapy and didactic resource in the communication process: subsidy to Nursing care with mothers of newborns under phototherapy. From the theme perception, we extracted in the first phase the sub-themes health of the newborn under phototherapy: the vision of the mother; separation of the binomial mother-son; the mother of the newborn under phototherapy and the hospital environment; and in the second phase, health of the newborn under phototherapy: what has changed? From the theme feelings, we extracted in the first phase the sub-theme impotence and sadness and in the second phase, mothers before the newborn under phototherapy: well-being and be better. As we concluded, the effective communication of the nurse contributed for the mothers to calm down and be better while they experience their child under phototherapy.
O processo de comunicaÃÃo da equipe de saÃde com a mÃe cujo filho està sob fototerapia à fundamental para que esta possa se tranqÃilizar e tornar-se conhecedora deste tratamento. A tese defendida nesta pesquisa à que a comunicaÃÃo permeada pelo cuidado humanÃstico de Enfermagem irà contribuir para a mÃe do neonato sob fototerapia poder vir- a - conhecer, compreender o tratamento e desse modo estar bem e estar-melhor. Objetivamos analisar a comunicaÃÃo com mÃes de neonatos sob fototerapia por meio do Processo da Enfermagem FenomenolÃgica da Teoria HumanÃstica de Paterson e Zderad. Estudo qualitativo, exploratÃrio e descritivo, instrumentalizado pelo mencionado processo, em suas cinco etapas: a preparaÃÃo da enfermeira para vir-a-conhecer; a enfermeira conhece intuitivamente o outro; a enfermeira conhece cientificamente o outro; a enfermeira sintetiza de forma complementar as realidades conhecidas; a sucessÃo interna da enfermeira a partir de muitos para um Ãnico paradoxal. Teve como cenÃrio uma maternidade pÃblica em Fortaleza-CE. Os sujeitos foram 25 mÃes internadas na referida instituiÃÃo, cujos filhos recÃm-nascidos (RN) se encontravam em tratamento fototerÃpico na Unidade de InternaÃÃo Neonatal (UIN) de alto, mÃdio, risco e/ou Alojamento Conjunto (AC), de janeiro a marÃo/2005. Utilizamos como tÃcnica a observaÃÃo participante e a entrevista individual, em duas fases, com a seguinte questÃo norteadora âO que significa para vocÃ, mÃe, presenciar seu filho sob fototerapia?â Na anÃlise dos dados da observaÃÃo participante pudemos visualizar as interaÃÃes mÃe/recÃm-nascido/enfermeira. Das falas extraÃdas de ambas as fases das entrevistas foram identificadas as seguintes temÃticas: comunicaÃÃo, conhecimento, cuidado, percepÃÃo e sentimentos. Da temÃtica comunicaÃÃo, extraÃmos na primeira fase as subtemÃticas comunicaÃÃo prejudicada com a equipe de saÃde; ausÃncia de comunicaÃÃo da equipe de saÃde e comunicaÃÃo mÃe â recÃm-nascido; e na segunda fase, reaÃÃes da mÃe apÃs comunicaÃÃo efetiva da enfermeira. Da temÃtica conhecimento, extraÃmos na primeira fase as subtemÃticas desconhecimento da fototerapia e a busca do conhecimento da fototerapia e na segunda fase, conhecimentos adquiridos acerca da fototerapia e compreensÃo do tratamento fototerÃpico: um novo olhar das mÃes. Da temÃtica cuidado, extraÃmos na primeira fase a subtemÃtica o neonato sob fototerapia - mÃes em busca do cuidado de Enfermagem e na segunda fase,cuidado-presenÃa: participaÃÃo da mÃe no cuidado ao neonato sob fototerapia e recurso didÃtico no processo de comunicaÃÃo: subsÃdio para o cuidado de Enfermagem com mÃes de neonatos sob fototerapia. Da temÃtica percepÃÃo, extraÃmos na primeira fase as subtemÃticas saÃde do neonato sob fototerapia: o olhar da mÃe; separaÃÃo do binÃmio mÃe-filho; a mÃe do neonato sob fototerapia e o ambiente hospitalar; e na segunda fase, saÃde do neonato sob fototerapia: o que mudou? Da temÃtica sentimentos, extraÃmos na primeira fase as subtemÃticas impotÃncia e tristeza e na segunda fase, mÃes ante o neonato sob fototerapia: bem-estar e estar-melhor. Conforme concluÃmos, a comunicaÃÃo efetiva da enfermeira contribuiu para que as mÃes pudessem se tranqÃilizar e estar - melhor enquanto vivenciavam o filho sob fototerapia.

Nos últimos 50 anos, o Brasil experimentou mudanças rápidas nas condições de vida e saúde de sua população, destacando-se a modificação de hábitos de consumo alimentar e a redução da atividade física, de caráter doméstico, de lazer, de ocupação e/ou de transporte. Objetivou-se estimar a prevalência das categorias de atividade física em adultos no estado de Pernambuco e analisar a relação do sedentarismo com fatores relevantes para sua ocorrência. Estudo transversal que utilizou o banco de dados da pesquisa Doenças crônicas e agravos não transmissíveis no Estado de Pernambuco, no ano de 2006, e contou com uma amostra probabilística de 1.768 indivíduos maiores de 25 anos. Para estimar o nível de atividade física utilizou-se o Questionário Internacional de Atividade Física (IPAQ), forma curta. Os indivíduos foram divididos em três grupos de acordo com o escore de atividade física: (a) Muito ativo; (b) Regularmente ativo; (c) Sedentário. A amostra foi recategorizada em apenas dois grupos: (a) Sedentários e (b) Suficientemente ativos. Análises uni e multivariadas foram realizadas por meio de regressão de Poisson com ajuste robusto do erro padrão, utilizando-se um modelo conceitual de fatores hierarquizados de determinação do sedentarismo. Os resultados foram expressos por razão de prevalência (RP) e IC 95 por cento. As associações foram avaliadas através do teste de Wald. No estado de Pernambuco a prevalência de sedentarismo foi de 34,1 por cento e 19,5 por cento muito ativos. O sedentarismo predominou nas mulheres, nos idosos, nas faixas etárias de escolaridade acima de 4 anos de estudo, os aposentados e residentes de áreas urbanas. O sedentarismo já se constitui num importante fator de risco de doenças crônicas não transmissíveis no Estado de Pernambuco. Estes resultados sugerem que intervenções e políticas públicas de promoção da atividade física devem considerar diferenças socioeconômicas, de gênero, bem como a idade e a localidade em que o indivíduo reside

Full textTitania (TiO2) is a widely studied material due to its low toxicity, high availability and to have properties that allow it to be used in a variety of photocatalytic applications. Its photocatalytic activity against the degradation of organic contaminants, for instance, can be even improved when preparing a mixture of phases of this material, as TiO2 P- 25 presents. However, its high band gap allows it to be used only when affected by high energy electromagnetic radiation (λ< 390 nm). The present work demonstrates that when TiO2 P-25 is synthesized in the form of mesoporous films, its band gap is reduced, and it starts to present photocatalytic activity under visible light. This reduction is attributed to the heat treatment that is applied during the preparation process of the material. In order to verify its activity in the absence of UV radiation, a study was conducted based on the analysis of the photodegradation rate of 2-naphthol, methyl orange and 2,4,6-trimercapto-1,3,5-triazine molecules by mass spectrometry using the compound ammonium hexafluorophosphate as an internal standard. The developed methodology can also be applied to conduct other semiquantitative assays via mass spectrometry. It was observed that TiO2 films induced 2-naphthol photooxidation under visible light and in the presence of oxygen gas after 6 hours of reaction. Photodegradation of methyl orange and 2,4,6-trimercapto-1,3,5-triazine was also confirmed, yet at a slower rate. The process was also observed by the identification of a methyl orange photooxidation by-product in the mass spectrum and from the decay of its absorption peak at 468 nm by UV-Vis spectrophotometry. It was also observed that titania may have its photocatalytic activity reduced by raising the pH of the medium. Furthermore, it was also produced titania films modified with gold nanoparticles through use of thioglycolic acid as a mediator and by drop casting method. Both techniques formed homogeneous films of gold nanoparticles over TiO2, and their photocatalytic activity were also evaluated. Nevertheless, the presence of the metal impaired the photocatalytic efficiency of titania by inhibiting its activity when excited by visible light. All in all, pure TiO2 P-25 films work under incidence of a wider range of the solar spectrum and has also the advantage of functioning as heterogeneous catalysts for photodegradation reactions of organic molecules and can be easily removed from the reaction medium at the end of the process.

Objetivos: Avaliar os efeitos de 6 meses de suplementação com colecalciferol e cálcio sobre o metabolismo mineral e sobre os parâmetros de força muscular de membros inferiores, oscilação postural e mobilidade funcional. Desenho do Estudo: Ensaio clínico prospectivo, randomizado, duplo-cego, placebocontrolado. Local de realização: Duas instituições de longa permanência para idosos, em São Paulo - SP, Brasil. Participantes: 56 idosos de ambos os sexos (12 homens e 44 mulheres), com 60 anos de idade ou mais (mediana=77,6; limites=62-94 anos). Métodos: Os pacientes foram randomizados em Grupo-Ca (n=28) para placebo, ou Grupo-Ca+D (n=28) para colecalciferol. Todos os participantes receberam 1000 mg/dia de cálcio. O Grupo-Ca+D recebeu colecalciferol oral nas doses de 150.000 UI/ mês durante os 2 primeiros meses de estudo e 90.000 UI/mês nos 4 meses subseqüentes, correspondendo a uma dose mensal de 3670 UI/dia em média, de Dezembro-2004 a Maio-2005. Níveis séricos de 25-Hidroxivitamina D (25OHD), paratormônio intacto (PTH) e cálcio foram mensurados no início do estudo (M1), 2 meses (M2) e 6 meses (M3) após tratamento. Os testes neuromusculares foram realizados antes do início da intervenção e repetidos após o fim do tratamento. A força muscular dos membros inferiores foi avaliada através de um índice de força muscular (IFM), incluindo a força dos músculos flexores do quadril e extensores do joelho, mensurada por dinamômetro mecânico portátil. Para avaliar a oscilação postural foi criado um índice (IOP) a partir da mensuração da oscilação do corpo nos diâmetros sagital e frontal ao nível da cintura. A mobilidade funcional foi mensurada através dos testes “Timed Up&Go” (TUG) e alcance funcional (TAF). Resultados: A 25OHD sérica aumentou em ambos os grupos no M2, porém mais no Grupo-Ca+D do que no Grupo-Ca (OR=2,2; 95%IC=1,98-2,4 vs. OR=1,76; 95%IC=1.55-1.99, respectivamente). No M3, os níveis de 25OHD declinaram apenas no Grupo-Ca, contudo, o PTH sérico diminuiu no M2 (p<0.0001) e retornou aos valores basais no M3 (p<0.0001) igualmente nos dois grupos. Antes do tratamento, deficiência/insuficiência de 25OHD (<50 nmol/L) afetava 67,9% do total de participantes. No M3, nenhum paciente do Grupo-Ca+D, mas 40% dos pacientes do Grupo-Ca tinham deficiência/insuficiência de 25OHD. Hipercalcemia não foi detectada em nenhum paciente. Apenas no Grupo-Ca+D, o IFM teve um aumento de 20% no M3 (OR=1,20; 95%IC=1,12-1,29), enquanto que IOP e TAF aumentaram igualmente nos dois grupos, provavelmente porque os pacientes de ambos os grupos aumentaram sua exposição solar durante o verão. Conclusões: A suplementação com colecalciferol e cálcio foi segura e efetiva em aumentar os níveis séricos de 25OHD, reduzir a prevalência de deficiência/insuficiência de 25OHD e aumentar a força muscular de membros inferiores nos idosos do grupo tratado. Palavras-chave: 25-Hidroxivitamina D, colecalciferol, idosos, força muscular, oscilação postural, mobilidade funcional.
Objectives: To assess the effects of a 6-month supplementation with vitamin D and calcium on mineral metabolism and parameters of lower-extremity muscle-strength, body sway (BS) and functional mobility, measured by the Functional Reach Test (FRT) and Timed Up&Go test (TUG). Design: Prospective, double-blind, placebo-controlled trial. Setting: Institutionalized elderly of two long-stay geriatric care units of São Paulo-SP, Brazil. Participants: 56 elderly volunteers of both genders (12 men and 44 women) of ages 60 and older (median=77.6; range=62-94 years). Methods: Subjects were randomized into a Ca-group (n=28) to receive placebo or a Ca+D-group (n=28) to receive cholecalciferol. All participants received 1,000 mg/day of calcium. Laboratory measurements were performed at baseline (M1), 2 moths (M2) and 6 months (M3) after intervention. The Ca+D-group received oral cholecalciferol on a monthly basis (3670 IU/day on average, from December-2004 to May-2005). Neuromuscular measurements were performed at baseline and 6 months. Results: Serum 25(OH)D increased in both groups at M2, but more so in the Ca+Dgroup than in the Ca-group (OR=2.2, 95%CI=1.98-2.4 vs. OR=1.76, 95%CI=1.55- 1.99, respectively). At M3, 25(OH)D levels declined only in the Ca-group. Nevertheless, serum PTH diminished at M2 (p<0.0001) and went back to baseline levels at M3 (p<0.0001) equally in both groups. Before treatment, 25(OH)D deficiency/insufficiency (<50 nmol/liter) affected 67.9% of the entire group. At M3, no patient in the Ca+D-group, but 40% of the Ca-group patients had 25(OH)D deficiency/insufficiency. Hypercalcemia was not detected at any time. The odds of improving lower-extremity muscle strength increased by 20% (OR=1.20, 95%CI=1.12-1.29) only in the Ca+D-group, whereas BS and FRT increased equally in both groups, probably because the study was conducted during the summer. Conclusions: The supplementation with calcium and supra-physiological doses of cholecalciferol was safe and effective in enhancing 25(OH)D levels, reducing the prevalence of 25(OH)D insufficiency, and increasing lower-extremity muscle strength in institutionalized elderly.

Full textThe purpose of this in vitro study was to evaluate the influence of different glass ionomer cement liners and curing techniques on the microleakage of resin composite restorations. Class V root cavities were prepared in the buccal surfaces of 120 bovine incisors. The specimens were divided into twelve groups of ten each, according to the liner and to the curing technique employed. Group 1- Single Bond + Z100; group 2- RMGIC (Vitrebond) + Single Bond + Z100; group 3- conventional GIC (Ketac Bond) + Single Bond + Z100, which were light cured by conventional technique; the other groups were restored similar to groups 1, 2 and 3, respectively; although, they were light cured by ramp technique (groups 4, 5, 6); pulse technique (groups 7, 8, 9) and high intensity (10, 11, 12). The thickness of the liner was 0.5mm and the resin composite was inserted in one increment. The four curing techniques were applied with different light intensities as follows: 450mW/cm2/ 40s (conventional), 100 - 800mW/cm2 /15s + 800mW/cm2/ 25s (ramp); 200mW/cm2/ 3s + 3 minutes delay + 600mW/cm2/ 30s (pulse); 1600mW/cm2/ 3s (high intensity). After 7 days, the teeth were thermocycled (500 cycles at 5oC - 55oC with a dwell time of 60 seconds) and immersed in aqueous solution of 0.5% basic fuchsin for 4h. Then, they were sectioned and the dye penetration was measured in millimeters by means of a computer program (Image Tool). Data were analyzed by two-way ANOVA and Tukey test. There were no significant differences among conventional, ramp and pulse techniques. The high intensity technique showed significant dye penetration when compared with others curing techniques. There were no significant differences in marginal leakage between the liners (conventional GIC and resin modified GIC), but the microleakage was significantly higher in the groups restored with no liner. No relationship between filling techniques and light curing methods was observed. It can be concluded that sandwich restorations were efficient in microleakage prevention, while the high intensity curing technique may lead to the highest dye penetration values in dentin cavities restored with resin composites.

Resumo: Introdução: O tratamento cirúrgico das doenças retinianas sofreu grandes mudanças nas últimas décadas. Na vitrectomia posterior via pars plana (VVPP) realizada com o sistema 20 gauge são utilizados instrumentos com 0.9 mm de diâmetro. Em 2002 foi proposto um novo sistema de vitrectomia posterior composto por instrumentos de 0.5 mm de diâmetro denominado sistema 25 gauge. Objetivo: O objetivo desse estudo é comparar os aspectos per e pós-operatórios das VVPP realizadas com os sistemas 20 e 25 gauge. Metodologia: Foram selecionados prospectivamente pacientes com indicação de vitrectomia apresentando as seguintes doenças retinianas: Buraco Macular idiopático (26 casos), Membrana Epiretiniana Idiopática (28 casos) e Hemorragia Vítrea secundária à Retinopatia Diabética (26 casos), totalizando 80 olhos de 79 pacientes. Após o exame pré-operatório inicial, os pacientes foram distribuídos aleatoriamente e igualitariamente em 2 grupos de acordo com a doença retiniana. O primeiro grupo foi submetido a VVPP com o sistema 20 gauge, enquanto o segundo grupo foi submetido a VVPP com o sistema 25 gauge . Os parâmetros analisados nos dois grupos foram: pressão intra-ocular, tempo cirúrgico, queixa do paciente no pós-operatório através de questionário objetivo sobre dor ocular, desconforto ocular, lacrimejamento, fotofobia e hiperemia ocular, e complicações per e pós-operatórias. O seguimento dos pacientes foi de 6 meses. Resultados: Em relação à presença de queixas pós-operatórias houve diferença entre as seguintes variáveis: dor (p= 0,008), hiperemia ocular (p = 0,014) e lacrimejamento (p= 0,034), com maior queixa para os pacientes submetidos à cirurgia com o sistema 20 gauge. A cirurgia com o sistema 20 gauge ocorreu em um tempo médio de procedimento igual a 39,3 (± 5,4) min enquanto a cirurgia com o sistema 25 gauge ocorreu em um tempo médio de procedimento igual a 23,7 (±7,9) min (p<0,001). Não houve diferença significativa da média da PIO em relação ao tipo de cirurgia realizada e o período de observação. Foram observados 3 casos de formação de bolha conjuntival no per operatório e um caso de endoftalmite no pós-operatório em pacientes submetidos ao sistema 25 gauge. Conclusão: Não foram observadas diferenças estatísticas entre as médias da PIO e o índice de complicações per e pós-operatório sendo o procedimento com o sistema 25 gauge realizado em menor tempo cirúrgico e oferecido maior conforto aos pacientes no pós-operatório
Abstract: Introduction: In the last decades, great improvement has been achieved on the surgical treatment of retinal disease using smaller diameter instruments. Nowadays, pars plana vitrectomy (PPV) is usually executed using the 20 gauge system, in which the instrument's diameter is 0,9mm. In 2002, a new posterior victrectomy system was proposed, using 25 gauge (0,5mm) diameter instruments. Purpose: To compare intra and post operative parameters of the PPV technique with 20 and 25 gauge. Methods: Patients presenting retinal disease, including idiopathic macular hole (26 cases), idiopathic epiretinal membrane (28 cases), and vitreous hemorrhage due to diabetic retinopathy (26 cases) with PPV indication were selected, with a total of 80 patients. After the initial evaluation, patients were randomly assigned to one of the two groups, according to the retinal disease. The first group was submitted to the 20 gauge system surgery and the second group, to the 25 gauge technique. Parameters observed were: intraocular pressure (IOP), surgery time, patients¿ complains on post surgical days through an objective questionnaire about ocular pain, ocular discomfort, tearing, photophobia, ocular redness and intra and post-operative complications. The follow-up of these patients was 6 months. Results: On post operative complains, difference was observed on the following parameters: ocular pain (p= 0,008), ocular redness (p= 0,014) and tearing (p= 0,034), with greatest complains between patients of the 20 gauge group. Median surgery time of the 20 gauge surgery was 39,3 (± 5,4) min; the 25 gauge system was executed in about 23,7 (± 7,9) min (p < 0,001). No significant differences were observed on median post-operative IOP measurements. Bubble conjuntival formation was observed in 3 cases in 25 gauge system. Endophthalmitis was observed in one case in the the group of 25 gauge system. Conclusion: The surgical procedures are equivalent when comparing the median intraocular pressure and the intra and post operative complications, but the 25 gauge system has the advantage of being less time consuming and offering the patient more comfort during the post operative period

Hypovitaminosis D has been studied in recent years and has a significant prevalence worldwide in all stages of life, especially in the elderly, which are at greater risk due to their reduced capacity to generate the vitamin D precursor in the skin, change in lifestyle and reduced practice of outdoor physical activity. Vitamin D deficiency has implications for health, among them, the inverse relationship with blood pressure. This study evaluated factors related to the prevalence of inadequate 25-hydroxyvitamin D levels and its relationship with blood pressure in elderly hypertensive patients belonging to Reference Health Centers of the city of Pessoa-PB/BR. A cross-section study was developed, where the following variables were analyzed: 25-hydroxyvitamin D, parathyroid hormone, magnesium, albumin, creatinine, glucose and ionized calcium, as well as blood pressure values, skin type, consumption of foods rich in vitamin D and BMI. For the descriptive statistical analysis of data, absolute distributions, percentages, means and standard deviations were used. Comparison between means of two continuous variables was performed using the Student t-test and for the analysis of variance, one-way ANOVA was used with significance level of p <0.05. The sample consisted of 91 elderly patients with mean age of 69.73 +7.0 years, 89% women and 11% men. The prevalence of vitamin inadequacy (25-hydroxyvitamin D <29 ng / mL) was 33% and in relation to other biochemical parameters, calcium and creatinine were significantly higher in the group of patients with inadequate levels; however, there were no values outside the cutoff point for each parameter in the entire sample. It is noteworthy that in the group of patients with inadequate levels, only 7.7% showed high PTH levels, but not confirming secondary hyperparathyroidism. There was no statistically significant association between skin type (p = 0.96), sun exposure (p = 0.71), permanence or not at home during the day (p = 0.39) and BMI (p = 0.91) with 25-hydroxyvitamin D levels in adequate and inadequate groups. Regarding the consumption of foods containing vitamin D, high fish consumption was positively associated with higher serum 25-hydroxyvitamin D levels (p = 0.006); on the other hand, the consumption of egg, whole milk and skim milk seemed not to influence. Regarding blood pressure, the mean systolic blood pressure was significantly higher (p = 0.03) in elderly patients with inadequate vitamin D levels, which did not occur for diastolic pressure (p = 0.26). It could be concluded that the prevalence of inadequate 25-hydroxyvitamin D levels was high and its relationship with higher systolic pressure levels is worrying. Based on results shown here, the weekly consumption of fish should be encouraged, since it may play a role in the hypertension treatment.
A hipovitaminose D vem sendo estudada nos últimos com uma prevalência importante no mundo inteiro em todos os estágios da vida, destacando-se a população idosa por apresentar maior risco devido a redução da capacidade de gerar o precursor da vitamina D na pele, mudança de estilo de vida e redução de atividades físicas ao ar livre. A sua deficiência tem implicações na saúde, dentre elas, a relação inversa com a pressão arterial. Neste estudo avaliou-se fatores relacionados à prevalência de níveis inadequados da 25-hidroxivitamina D e sua relação com a pressão arterial em idosos hipertensos pertencentes a Centros de Referência e Cidadania da cidade de João Pessoa-PB/BR. Foi desenvolvido um corte transversal sendo analisadas: 25-hidroxivitamina D, paratormônio, magnésio, albumina, creatinina, glicose e cálcio ionizado, assim como registro da pressão arterial , tipo de pele, consumo de alimentos fonte vitamina D e IMC. Para análise estatística descritiva dos dados, foram utilizadas distribuições absolutas, percentuais, médias e desvio padrão. A comparação entre médias de duas variáveis contínuas foi realizada por meio do Teste T-Student e para análise de variância ANOVA- one way, com nível de significância de p<0,05. A amostra foi de 91 idosos com idade média de 69,73 +7,0 anos, sendo 89% mulheres e 11% homens. A prevalência da inadequação da vitamina (25-hidroxivitamina D <29 ng/mL) foi 33% e em relação aos demais parâmetros bioquímicos analisados, o cálcio e creatinina mostraram-se significativamente maiores no grupo dos idosos com níveis inadequados, entretanto, não ocorrendo valores fora do ponto de corte de cada parâmetro em toda amostra. É pertinente destacar que no grupo dos idosos inadequado, apenas 7,7% mostraram níveis de PTH elevados, porém não afirmando hiperparatiroidismo secundário. Não foi encontrada associação estatística significativa entre o tipo de pele (p= 0,96), exposição ao sol (p= 0,71), permanência ou não em casa durante o dia (p= 0,39) e do IMC (p= 0,91) com os níveis de 25-hidroxivitamina D nos grupos adequados e inadequados. A respeito do consumo de alimentos fontes de vitamina D, o maior consumo de peixe foi positivamente associado com maiores níveis séricos da 25-hidroxivitamina D (p= 0,006), por outro lado, o consumo de ovo, leite integral e desnatado, não se mostraram influenciar. Ao se estudar os níveis pressóricos, a média da pressão arterial sistólica foi significativamente maior (p= 0,03) nos idosos com níveis inadequados da vitamina, não ocorrendo o mesmo para pressão diastólica (p=0,26). Conclui-se que a prevalência da inadequação dos níveis da 25-hidroxivitamina D foi elevada e sua relação com níveis mais altos da pressão sistólica é preocupante. Pelos resultados aqui mostrados, sugerimos incentivo ao consumo semanal de peixe, visto que podem ser coadjuvantes no tratamento da hipertensão.

Full textA cana-de-açúcar é a matéria prima que depois de industrializada origina vários derivados, tendo como principais o açúcar e o álcool. Após o processo de fermentação do caldo e posterior destilação, originam-se o álcool e a vinhaça. Essa, que antes era considerada poluente, atualmente é utilizada, com zelo, para a melhoria das propriedades biológicas, físicas e químicas do solo. O presente trabalho visou avaliar, em laboratório, as modificações e deslocamentos de alguns atributos físicos e químicos em dois Argissolos que recebem vinhaça há mais de 25 anos, nas usinas Marituba (UMA) e Sto Antonio (USA), localizadas na região canavieira de Alagoas, Brasil. Foram utilizadas amostras de solos coletadas em cinco camadas (0-10, 10-20, 20-40, 40-70 e 70-100 cm) do perfil do solo, em que se aplicou o fatorial 22x5 [(2)usinas-(2) com vinhaça (CV) e sem vinhaça (SV)-(5)camadas], totalizando vinte tratamentos com quatro repetições. Pelos resultados, se observou que a vinhaça promoveu alterações significativas no solo. Os atributos: pH, P, K+, Ca2++Mg2+, Matéria Orgânica do Solo (MOS), Carbono Solúvel em Água (CSA), percentagem de potássio trocável na capacidade de troca de cátions em (%KCTC) e porosidade apresentaram diferenças significativas a 0,01 de probabilidade pelo teste F. As variáveis, densidade do solo (DS) e argila, apresentaram diferenças significativas a 0,05 de probabilidade e capacidade de troca de cátions (CTC) e areias foram não significativas (NS). Para as variáveis do solo houve significância a 0,01 para: pH, P, K+, Ca2++Mg2+, MOS, CSA, CTC, areias e porosidade, enquanto as variáveis % K+ CTC e DS foram NS. Na interação de vinhaça com camadas, houve diferenças significativas pelo teste F a 0,01 para P, K+, Ca2++Mg2+, MOS, CTC, DS, % K+ CTC e areias. Houve diferença significativa a 0,05 para pH, CSA e argila. Na interação de vinhaça com camadas, as diferenças a 0,01 foram para P, Ca2++Mg2+, MOS, CSA, e % K+ CTC, com 0,05 de probabilidade, as variáveis CTC e DS apresentaram diferenças significativas, já pH, K+, CTC, areia, argila e porosidade foram NS. Comparando as médias entre as áreas com e sem vinhaça, pelo teste de Tukey a 0,05, tem-se médias maiores para camadas da área que receberam vinhaça, para pH, P, K+, Ca2++Mg2+, CSA, DS e % K+ CTC. Foram semelhantes para CTC e areias, porém, na área que não recebeu vinhaça apresentaram superioridade: MOS, argila e porosidade. Os dados obtidos no presente trabalho indicam que a adição de vinhaça ao solo foi benéfica e por isso se recomenda a manutenção de seu uso, diante da comparação entre o benefício e o prejuízo que a vinhaça poderá causar.

Full textThe peripheral nerves are extensions of the central nervous system and are responsible for the sensory and motor functions of the limbs. These nerves are vulnerable to the same types of traumas that affect other tissues: contusion, compression, crushing, stretching, avulsion, and laceration. Amongst the most disabling kinds of injuries that affect working-age individuals are those of the peripheral nerves; due to the multifaceted characteristics of the aftereffects of the injury. The break in continuity of the nerve structure due to trauma, as in the case of neurotmesis, results in the disruption of the transmission of nerve impulses and the disorganization of their functions. Through the use of microsurgery, it was possible to develop reconstructive techniques that range from a simple end-to-end neurorrhaphy to sophisticated surgical procedures that utilize nerve grafts, inverted veins and arteries, and synthetic rods of varied materials such as silicone or porous polyethylene. Another aspect that intrigues researchers around the world is the utilization of neurogenic factors capable of accelerating or improving the regeneration of peripheral nerves. Autologous fat has been a constant reference in this field of surgery due to its abundant supply at the surgical site itself. The results are promising, as the adventitia of vessels consists of loose connective tissue rich in adipocytes. Thus in a trauma, the neurites derived from the proximal stump of the damaged nerve are in direct contact with these adipocytes. Following this reasoning, and based on previous studies where veins grafted with fresh skeletal muscle were used, we decided to conduct a randomized controlled study to test the possibility of axonal growth by means of grating with a polyethylene rod filled with autologous adipocytes associated with immersion in a hyperbaric chamber. In an attempt to recover the sciatic nerve, a rod 12 mm in length, with a diameter of 0.25 mm, and with pores of 80 μm in diameter, filled with adipose tissue in natura removed from the surroundings of said nerve, was used. The morphometric results showed that the experimental groups with and without fat fillings had results that, from the morphometric and functional point of view, were of no statistically significant difference. However, when these results were compared with the final control group, statistically significant differences were noted. Highlighting the functional evaluation through the use of Catwalk, it was found that there were no statistically significant differences between the experimental groups, but there was indeed a difference in comparison to the final control group. In light of the evidence found and supported by literature, one can conclude that the use of the hyperbaric chamber brought positive results verified by the proximity of both the morphometric and functional results of the experimental groups.

Full textSome theories postulate the auditory perception to complex sounds and simple sounds, occur differently. Theories about the existence of a special route for decoding speech, with distinctions from the detection of the acoustic spectrum, nonlinear depolarization of the auditory nerve fibers to the location of specialized neurons to interpret speech sounds at the cortical level. Is it possible this specific skill of speech perception a factor that would change the responses of children aged 6 to 24 months during a behavioral assessment? For audiological evaluation in this age group, with Visual Reinforcement Audiometry (VRA) is the test to obtain minimum response levels (MRL) or thresholds. Faced with these questions, determined to carry out a comparative study of the VRA with two stimuli: warble tones in the frequencies of 0.5, 1, 2 and 4 kHz, and speech stimuli, the six Ling sounds /a/, /i/, /u/, /s/, /?/, /m/. Both tests were applied in children with and without hearing impairment with the objective of determining the NMA, test time, number of sessions and the behavior observed during the assessment. In addition to quantitative research, we designed a guide guidelines for conducting the VRA. 123 children were evaluated, of which 57 were included in the survey, the main reasons for exclusion were changed tympanograms, multiple disabilities, delayed motor and auditory neuropathy spectrum disorder. Participated in the control group (CG) 33 children without hearing impairment, mean age 12 months, and 24 with hearing loss in the experimental group (GE), average age of 18 months. In total 718 were obtained NMA considering the 57 children and 10 evaluated stimuli. For the GC average of VRA-warble was 17.05 dBHL and for VRA-Ling of 13.60 dB HL; GE in the averages were respectively 95.51 and 85.88 dBHL dBNA, ie, statistically the values obtained with the sounds of Ling were lower than those obtained with the warble stimulus. The average time to achieve at least one or all of the NMA NMA with Ling and warble, did not differ compared intra groups, as well as the number of sessions. However, it was noted in comparison between groups, the number of sessions, the number of NMA obtained and the and the test time in achieving VRA-warble were higher in the EG. Other behaviors were observed during the course of the VRA: attention, orientation reflex, imitation of auditory stimuli, point to the phone, look appraiser / mother. Considering the results obtained: the test protocol used was effective for obtaining the NMA in both groups; Ling sounds can be used in the audiological evaluation of children to complement the findings with specific frequency stimuli. However, since Ling sounds have a wide range of frequencies, other studies correlating to NMA Ling sounds in different audiometric configurations are needed.

Full textThe aim of this study was to evaluated facial harmony in patients with open bite, in front teeth (both upper and lower) treated with orthognatic surgery or orthodontic correction by using frontal and lateral side photograph. The purpose of this study was to divide 30 patients in two groups. GROUP 1: patients using bite correction; GROUP2: patients treated with orthognatic surgery. Both groups were studied by orthodontics and ordinary people. Those photographs were divided in different sectional appliance and showed at Power Point and were studied. The results of each group were compared, considering the evaluation from top to bottom, of which one provides a better facial harmony. No significant differences could be notice between the orthodontist opinions such as the ordinary people; however, those ordinary people had a more critical argument about the results. They established different treatments for those patients. Those who had the orthognatic surgery had a better response.

Full textIn cases of dysphonia, it is necessary the active participation of the patient to speech therapy, evincing the importance of studies about the motivational aspects and the anxiety and depression influence. Accordingly, the literature has been showing the applicability of the Transtheoretical Model Stages of Change in clinical management. This model studies the individual\'s behavior changes as well as the motivation it demonstrates to change a specific behavior. Searching further clarifications about patient\'s motivation, this study aimed to identify the motivational stages and the correlation between these stages and the levels of anxiety and depression in patients with dysphonia. Have participated 41 persons in the 18 and 55 years old age group with functional or organofunctional dysphonia. They all answered the scale University of Rhode Island Change Assessment (URICA) adapted to voice, called URICA-Voice, to identify the motivational stages for change, the State-Trait Anxiety Inventory (STAI) and the Beck Depression Inventory (BDI). Most participants 30 (73.17%) of this research lies in the contemplation stage, seven (17%) in the action, 4 (9%) in the precontemplation stage and none of the participants laid in the maintenance stage. Significant correlation was found between the average of corresponding points the contemplation stage the issues of URICA-Voice scale and the total average obtained in the STAI-T inventories (p = 0.002) and STAI-E (p = 0.028), and more correlation strength to trace than to the state, it means that the score obtained in the contemplation stage is directly proportional to the average results for the STAI-T, STAI-E. The results also suggested a trend toward significance of the correlation between the contemplation stage and BDI (p = 0.07). In our data set found the importance of including instruments and MTT tools to clinical protocol in Voice area and in the design of new studies to further clarification of the interference of low motivation and its relationship to symptoms of anxiety and depression in patients dysphonia, which may cause constraints on the results of treatment.

Full textThe success of a quality education comprises several factors that are related and added to a significant educational process, among them: physical and financial structure, public education policies and professional quality training. The teacher works with students who have different profiles, and learn of various forms. In the midst of the diversity are those students that present Specific Learning Disorders. Therefore, an important issue concerns: how the teacher build their knowledge to meet the educational needs of this student? Besides: in a classroom setting with diverse needs, what guides teachers practice and what is modified when they find a student with a Specific Learning Disorder? Thus, the present study aimed to develop and apply a program of professional training on the specific learning disorders to deepen theoretical and practical knowledge of teachers from 1st to 5th grade of elementary school, measured from a prior questionnaire. So, it was provided an update course for teachers of 58 hours with the theme of the Specific Learning Disorders. After the intervention, the course of continuous formation process update, there was significant improving in the teacher´s speech about the practices in the classroom, highlighting the importance of professional training to contribute to the discussion and knowledge on the subject of Specific Learning Disorders, both in initial mode as in continued mode.

Full textThe objective of this research was to compare the fracture resistance upon axial compressive loads of maxillary premolars endodontically treated with MOD preparations restored with ceramic (IPS-Empress 2) and ceromer (Targis) inlays cemented with three dual luting cements (Enforce, Variolink II and Panavia F). Sixty premolars free of caries or fractures, extracted for orthodontic purpose were selected. They were similarly distributed according with their bucco-lingual and mesio-distal dimensions in 6 groups determined by the combination of the restoring materials and luting agents. After cementation and thermocycling procedures, the teeth were fixed in a Universal Test Machine and subjected to an axial compressive load by action of a 8mm wide steel cylinder, at the speed of 0,5mm/min., contacting only the inner aspects of the buccal and lingual cusps. The results were, in decreasing order, as follows: Enforce (107,57kgf e 90,21kgf), Variolink II (86,44kgf e 84,07kgf) and Panavia F (82,43kgf e 76,73kgf), for inlays restored with Targis and IPS-Empress 2, respectively. They were found statistically significance differences between Enforce and Panavia F, independently of the restorative material. Considering the same luting agent, the results obtained with Targis restored groups were slightly superior of those restored with IPS-Empress 2, with no statistically significance difference.

Full textThe skeletal muscle is an extremely versatile entity, able to change their patterns and phenotypic characteristics under various conditions such as neuromuscular activity, electrical stimulation, age, hormonal activity and exercise. It is also known that the balance between atrophic and hypertrophic stimuli directly control the muscle mass of the individual and these changes directly affect not only on muscle volume, but also protein content and production strength. In this sense, muscle atrophy (loss of muscle mass) characterized by both, the decrease in cross-sectional area of muscle fibers, but also by decreasing the content of myofibrillar proteins and consequent reduction in muscle volume. This muscle atrophy may occur in various pathological conditions, resulting in decrease or loss of lean body mass leading to a consequent reduction in physical function, quality of life and even worse response to treatment, thus leading to increased mortality. It is clear in that way that the methods aimed at preventing or treating muscle atrophy has important clinical relevance in many groups of patients, as well as being a major contributing factor in the quality of life and autonomy of individuals. Thus, the study of certain treatments that combat muscle atrophy become of vital importance, among which highlight is winning the β-hydroxy-β-methylbutyrate (HMB). Thus, it is aimed in this study to assess the effectiveness of HMB to prevent muscle atrophy induced by dexamethasone (DEXA). For this, we used 32 Wistar animals aged 60 days, distributed in the following groups: experimental group Placebo (GEP), n = 8, treated for 10 consecutive days with gavage and intraperitoneal injection, both containing only saline. Experimental group Dexamethasone (GED), n = 8, treated for 10 consecutive days with gavage containing saline and intraperitoneal injection containing dexamethasone. Experimental group HMB (GEH), n = 8, treated for 10 consecutive days with gavage containing HMB and intraperitoneal injection containing saline solution and Experimental Group Dexamethasone + HMB (GEDH), n = 8, treated for 10 consecutive days with gavage containing HMB and intraperitoneal injection containing DEXA. The animals were placed in collective boxes with 4 animals per cage with food and water at will in a room with 22o temperature and respecting the light / dark 12-hour cycle. Completed the ten days of treatment, the animals were euthanized to collect the material. After the analysis, the mean body weight to groups of animals, muscle weight and values of morphometry were all subjected to one-way ANOVA followed by Tukey test, with the amount considered statistically significant at p <0.05. At the end, it could be concluded that the experimental design applied here, the HMB was not able to mitigate or prevent the loss of body weight induced by DEXA, and the anti-catabolic effect expected by HMB not reflected in the EDL muscle, but was able to prevent atrophy in the soleus muscle.

Full textLead (Pb) is a heavy metal that may yield changes in all body systems, yet the greatest health damages occur when it affects the central nervous system (CNS). Many studies demonstrate the clinical/behavioral changes caused by the action of Pb on the CNS. However, studies are necessary to demonstrate the biochemical changes caused by Pb in this system. Conversely, it has been reported that iron (Fe) seems to play a protective role on the brain toxicity caused by Pb. Therefore, this study analyzed the concentration of Pb in the brain tissue, and conducted proteomic analysis in the brain of rats intoxicated by Pb, submitted or not to Fe supplementation. The study was conducted on 30 weaning rats (Rattus norvegicus, Wistar type) divided in 6 groups (n=5/group), according to the treatment established for 6 weeks, as follows: Control (not exposed to Pb or Fe), Control Fe (exposed to administration of 20 mg/Kg p.c. of FeSO4 at every 2 days, by gastric gavage), Pb 100 exposed to water containing 100 mg/L of Pb), Pb 400 (exposed to water containing 400 mg/L of Pb) Pb100 + Fe (exposed to water containing 100 mg/L of Pb and gavage with FeSO4) and Pb400 + Fe (exposed to water containing 400 mg/L of Pb and gavage with FeSO4). After the experimental period, the animals were killed and the brains of animals were removed, discarding the cerebellum and brainstem. The remaining structure was submitted to analysis of Pb concentration and proteomic analysis. A dose-response relationship was observed in Pb concentration in the brain. The administration of FeSO4 reduced the levels of Pb in the brain, though without statistical significance. The analysis of gels with proteic spots demonstrated reduction in their quantity according to the treatment performed in the groups. The control group exhibited greater concentration of spots, while groups receiving higher Pb concentration (400 mg/L) presented the lowest quantity of spots. There was also reduction in the quantity of spots detected when FeSO4 was administered. Among the spots presented different expression in the comparisons between the control group and experimental groups and between the experimental groups and their counterparts supplemented or not with FeSO4, 75 proteins were identified by mass spectrometry, being 20 proteins (26.0%) related to metabolic functions, 21 proteins (28.0%) related to structure and organization of structures, 22 proteins (30.0%) related to cell functions and processes, nine proteins (12.0%) related to information pathways and three proteins (4.0%) from the miscellaneous category. The expression of proteins was reduced in most cases, for all functional classifications. The present study, combined to previous findings, indicates a harmful effect of Pb in the cerebral cortex of animals exposed to this metal, regardless of the concentration employed, without observation of a protective effect of FeSO4. This process seems to be mediated by proteins as Gamma-enolase, Alpha-internexin, several isoforms of 14-3-3 and Homer protein homolog 1.

Full textThe purpose of this study was to verify "in vitro" measures and possible correlations between seating discrepancy, marginal opening and microleakage pattern under total metallic crowns cemented with three types of luting agents: phosphate, glass-ionomer and resin dual cement. Thrirty extracted human premolars teeth were prepared for total metalloceramic crowns and castings obtained with a Ni-Cr alloy. Samples were ramdomly assigned for three groups in according to each luting agent: zinc phosphate (S.S.White), resin-modified glass-ionomer (Vitremer-3M) or a dual resin cement (Enforce-Dentsply). Cementation was done under a 49N load for 10 minutes and water stored for 24hs. Vertical discrepancy was registered before and after cementation in an optical microscopy with the accuracy of 0,001mm). Half of the specimens within each group was submitted to a cyclic loading test (50000 cycles, 2,5Hz). Crowns were longitudinally seccionated in a bucco- lingual plane at the tooth-cement-crown interface and dye solution (rodhamine B) was apllied to tooth-cement- interface for 15 seconds The linear stain penetration along tooth-cement was quantified. under a light microscope (80X magnification) and then samples were prepared for scanning electronic microscope in order to quantify marginal opening and the quality of interface. The results for seating discrepancy were higher for zinc phosphate, followed by glass-ionomer and resin cement, with no statistical difference. Statistically significant differences were found between seating discrepancy and marginal opening for the three cements. Microleakage results were higher for zinc phosphate, followed by glass-ionomer and resin cement, with statiscally significant differences. Fatigue loading rinsed marginal leakage for zinc pohsphate, with statiscally significant difference in respect to glassionomer and resin cement. Scanning electron microscope analysis showed better marginal quality at the tooth-cement-restoration interface for resinous cement,followed by glass-ionomer and zinc phosphate cement.

Full textHearing impairment, defined as the total or partial loss of hearing, has been described in various reports as one of the factors that can interfere in the interaction between parents and children and as a result, with the emotional and social development of children with hearing loss. In this case, studies showed the need of new strategies, combined with speech therapy, in order to improve this interaction. In this context, the development of two studies were proposed, which took place at the Clinical School of Speech and Hearing Therapy - Dental School of Bauru - Univesity of São Paulo. In study 1 the objective was to identify, by means of the speech of the participants, the scenarios and characters of an educational tool called My World, which is used in the speech therapy for children and adolescents with hearing loss, it is used to learn new ways to develop social skills as part of the daily routine between children and parents. Three mothers of pre-adolescents with hearing loss aged 10 to 11 years old participated. The tools scenaries and characters were presented to the mothers, who responded in a questionaire their opnions on how this tool had helped them interact with their childrens activities and behaviour on a daily basis. Study number 2 was developed using the skills and tools learnt in study number 1, which was used as a support resource to enhance and develop positive parental practices. The main aim of this study was to evaluate the effects of the intervention on the range of behaviors between mothers and sons with hearing loss. Therefore, this experimental design was tested by two groups, control (CG) and experimental (EG), and they were tested before and after the experiment took place. Four mothers of pre-adolescents with hearing loss aged 10 to 12 years old beloging to the groups GC and two to the group GE were used.To evaluate the range of behavior of mothers and their sons in the pre and post-test, the Roteiro de Entrevista de Habilidades Sociais Educativas Parentais (RE-HSE-P) and the Child Behavior Checklist (CBCL) were applied. The mothers of the EG responded to the tools four months after the end of the intervention. The program was developed in 10 sessions, each lasting 1 hour and 30 minutes each. The topics developed were hearing impairment and social skills and parental practices identified as inadequate in the pre-test. For this data analysis of RE-HSE-P, the Jacobson Truax method was used, which indicated reliable changes in relation to the incremental positive parental practice and infantile social skills for the EG. The CBCL data indicated internalizing behavior problems in the EG and a participant in the CG and externalizing behavior problems in a participant of the CG in the pre intervention stage. This data remained similar in the post-intervention data and in the follow-up evaluation for the EG. It is believed that the implementation of semi-structured interventions to develop positive parental practices, supported by scenarios and characters of the My World tool, can constitue an importante ally of speech-language therapy contributing to the climate of improved communications within the family context.

Full textBackground: Clinical evidence shows that pharyngeal obturator can stimulate Passavant´s pad formation in subjects with VPI current from cleft palate. It puts those subjects as better candidates for VPI treatment either surgical correction or pharyngeal obturator. Aim: The present study aimed to investigate Passavant´s pad occurrence in cleft palate subjects, who wore pharyngeal obturators, in the following conditions: before pharyngeal obturator´s confection (condition C1), during pharyngeal obturator molding (condition C2) and after six months wearing the pharyngeal obturator (condition C3, without the pharyngeal obturator and condition C4 with the pharyngeal obturator). Method: The sample was composed by 25 subjects (15 male and 10 female), age range between 18 - 59 years (range = 32 years). All patients had VPI current cleft palate surgery and were pharyngeal obturator wearers for at least six months. All subjects were submitted to nasoendoscopy evaluation during speech, with and without the pharyngeal obturator. The 75 recordings, 25 during condition C1, 25 during C2 and 25 during C3 and C4, were edited in a DVD and rated by five experienced speech pathologists, named judges. The judges had to rate the following aspects: a) nasoendoscope position during the exam; b) pharyngeal obturator size, according velopharyngeal space; c) Passavant´s pad occurrence; d) intercurrences that compromise pharyngeal walls observation. The judge´s rating protocols were based and adapted from the one proposed by Golding-Kushner et al. (1990). Results: Intra judge agreement for every rated aspect was considered, in range, almost perfect (83%), and the inter-judge agreement varied between regular (35%) and almost perfect (100%). The ratings were compared to each other, in every conditions, for all analyzed aspects. The only statistical significant comparison was in Passavant´s pad occurrence, between conditions C2 and C4. Data revealed that the Passavant´s pad occurrence varied, in one o more conditions, in 14 (56%) subjects and, in 11(44%) didn´t show any change. Conclusion: Findings allow us to conclude that, the pharyngeal obturator may act as a stimulus factor for Passavant´s pad formation in patients with VPI current from cleft palate.

Full textPeripheral nerves are extensions of the central nervous system and are responsible for the interaction of the activities of the extremities in their sensory and motor function. They are vulnerable to these types of injuries that affect other tissues: contusion, compression, crush, stretch, tear and avulsion. Thus, the interruption of continuity of the nerve structure, due to some sort of trauma, results in the interruption of transmission of nerve impulses and disruption of their functional activities. Therefore, in view of technological evolution and development of more sophisticated equipment, microsurgery is gaining more space in the field of experimental research concerning the recovery of injured peripheral nerves. In a single section, without loss of tissue, called the end-terminal neurorrhaphy was also good, however, when there is loss of nervous tissue or, if not longer have the distal nerve stumps, other techniques must be employed, because, in any circumstance the nerve should be tensioned as an attempt to coaptation again. Several techniques of tubing, using biological materials and non-biological means to create a place where nerve regeneration have been or are still being tested with unsatisfactory results in the functional aspect. It is known that in a trauma without loss of tissue, a neuropraxia, for example, the nerve recovers spontaneously and satisfactorily. It is also known that in a neurovascular bundle, the peripheral nerve is in close contact with the adventitia of arteries and veins. The adventitia of the vessels is composed of loose connective tissue rich in adipocytes. Thus, in trauma, the neurites from the proximal stump of injured nerve, are directly in contact with these adipocytes. Following this reasoning, and based on previous work where it was used vein filled with fresh skeletal muscle as a graft, decided to test the possibility of axonal growth by grafting polyethylene tube filled with autologous adipose tissue. For that will be used with a tube 12 mm long and 0.25 mm in diameter, with pores of 80 microns in diameter, filled with fresh adipose tissue removed from the vicinity of that nerve, in an attempt to recover the sciatic nerve. Certification of successful nerve recovery will be done through microsurgical techniques, microscopy and morphometry. The graft polyethylene proved to have pressure resistance, since no structural collapse was observed. The fat was found to be good material as trophic group which had used the results closer to the ultimate control.

Full textDue to safety and promising results observed in the setting of auditory rehabilitation by cochlear implant (CI), the indications of the CI started to include other children with hearing loss and additional disabilities. Among the groups of children with hearing loss and additional disabilities, the children with cerebral palsy (CP) showed the best results after the CI. The purpose of this study was study the benefits in hearing, language and communication after the use of CI, and investigate aspects of motor development, performance and level of independence in activities of daily living have relationships with the progress in CI. The group was formed by eight children with CP and CI users for at least six months. The children were assessed three times, with total follow-up of 24 months. The aspects evaluated were: hearing, language, communication, motor development, level of independence and functional performance in daily activities, in different areas: Self-care (SC), Mobility (MOB) and Social Function (SF). The main procedures used in the evaluation were: Observation of Communicative Behavior (OCC), Denver Development Screening Test (DDST II), Pediatric Evaluation of Disability Inventory (PEDI), the Hearing Categories and Categories of Expressive Language. All children developed the cochlear implant, in the matters of hearing, language and communication, but with different rates. The motor development and functional performance in SC, MOB, and FS showed significant progress from the time of assessment. The level of independence (caregiver assistance) did not show significant changes. Children with better language scores in the DDST II had the best scores in the OCC and in the hearing categories, as well as other associations between the auditory and motor function, social skills and SC were observed. The progress with the cochlear implant for children with cerebral palsy was possible, but with different rates for each child. The measurement of aspects of functionality provided an overall analysis of the child, and this is important to describe the child with cerebral palsy and enrich the guidance of parents. The CI provided benefits in hearing and language, which are the main factors to establish a form of communication. The ability to communicate is a positive factor and acts as a main point in the social inclusion of children with cerebral palsy, improving quality of life.

Full textThis work analysed the theoretical and experimental behaviour of reinforced concrete columns under axial compression force with concrete compressive strenght around of 25 MPa. In the experimental stage it was tested 16 specimens with cross sections of 200 mm x 200 mm and 150 mm x 300 mm. The height of the columns were six times the smallest dimension of the cross section, i.e., 1200 mm and 900 mm, respectively. Besides the dimensions of the columns, other parameters, like longitudinal reinforcement ratio and the spacing and arrangement of the transverse reinforcement were varied. The columns were loaded concentrically in an servohidraulically controlled testing machine that permitted applying the compression force with displacement control. Therefore, it was possible to obtain the force-strain curve post-peak. The results showed that were not formed resistent cores. Cracks appeared in a load stage near the failure of the specimens. For the transversal reinforcement ratio adopted, it was verified a small gain in strength and an significant increase in ductility. At last, the supplementary cross ties provided gain of strength and ductility in the columns.

Full textThe long-term stability of the treatment outcomes presents as one of the main points in orthodontic literature, without conclusive answers. The overbite is defined as the vertical distance between upper and lower incisors, and it is important for malocclusions correction and for evaluation of treatment and its stability. This study aimed to evaluate, in cephalograms and study casts, the overbite relapse and its relation with the curve of Spee. The sample (experimental group) comprised 29 patients of both genders, presenting Class II, division 1 malocclusion and an overbite of at least 3.5 mm, treated by Edgewise mechanics. This experimental group was compared to a control group of normal occlusion, comprising 29 subjects. Both groups are part of the records from Orthodontic Department at Bauru Dental School, University of São Paulo. For the experimental group, cephalograms and study casts of the pretreatment, posttreatment and 5 years postretention were studied, and for the control group, cephalograms in two times of evaluation, compatible with the treatment time of the experimental group. The independent t test was used for the intergroup comparison, and the one way ANOVA, for intragroup comparison. In order to verify the relation between the overbite relapse and the curve of Spee, a Pearson's correlation test was performed. The results showed that the overbite was significantly corrected by the orthodontic treatment, when compared to the control group, and presented a significant relapse in the postretention phase. The overbite relapse presents a significant correlation with the curve of Spee in the postretention stage

Full textIntroduction: After dental extraction, the natural repair process of the alveoli occurs a undesirable remodel in alveolar ridge, with dimensional changes that result in the reduction of same. This post-surgical sequel is characterized by resorption of the alveolar process and brings complications for an aesthetic and functional rehabilitation, as the alveolar ridge gets their morphology and volume changed. Objectives: The objective of this study was to verify whether a device of minimally traumatic extraction has the potential to minimize this sequel which occurs after tooth extraction, compared to the conventional surgical technique. Material and methods: 12 patients were randomly divided into 2 groups according to the surgical approach they would receive. In the control group the dental extraction was made with conventional technique and instruments, as levers and extractors, and in the experimental group with Neodent ® Dental Extractor. Both groups had the spontaneous healing of the alveoli monitored by 6 months, with measures of clinical and radiographic bone height, gingival height and thickness, parsed through the scanning of plaster models, in addition to the evaluation of surgical clinical time and postoperative pain. Results: The results showed that after 6 months of repair, both groups showed a decrease of the original measures, namely, dimensional variation. Although the experimental group performed superior in almost all analysed aspects, there was no statistically significant difference, except in the height of gingival distal area. Conclusions: The use of Neodent ® Dental Extractor seems to be able to help in the preservation of the alveolar ridge dimensions post tooth extraction.

Full textThirty patients were evaluated in this study, 15 males and 15 females, leukoderm, Brazilian, natural from Bauru city, with initial ages ranging from 10.83 years to 16.24 years, being the average age 13.32 years old. They were characterized by Angle Class II division I and II malocclusion, with or without the second maxillary molars, and, no skeletal compromising. The patients were treated with the appliance Jones jig. The treatment last for 0.86 years. It´s purpose was the distalization of the first maxillary molars to normal molar relationship. After this movement, the maxillary molars were anchored with Nance button, and extraoral headgear was used to correct tipping of the distalized molars. Lateral cephalograms were obtained at two observation stages: before treatment, and after distalization to evaluate dental and skeletal changes of appliance Jones jig. Cephalometric values were submitted to: dependent sample Student t test to identify changes between T1 and T2, and, independent sample Student t test to evaluate generic dimorphism and the effects from the presence of the second maxillary molars. On the basis of obtained results and applied methodology, significant dental changes were observed, such as distalization, distal tipping, and, intrusion of first maxillary molars, with the monthly rate of distal movement being 0.26mm. Anchorage loss was also observed, characterized by significant extrusion; mesial movement and tipping of the maxillary second premolar; protrusion of the maxillary incisors; and, increase of the overbite and overjet. It can be said that some dental movements promote significant skeletal changes, such as, significant extrusion of the second maxillary premolars resulted in clockwise mandibular rotation, increase of the lower anterior face height, and, protrusion of the lower lip. Another fact also observed was that the presence of second maxillary molars interfere significantly on the first maxillary molars?s distal tipping results, and, that the variables correlate significantly amongst themselves.

Full textThis study evaluated the fracture resistance of endodontically treated teeth reconstructed with cast metallic posts or different restorative procedures using glass fiber posts. Fifty canines were sectioned at the cementoenamel junction, endodontically treated and fixated in acrylic resin blocks. Teeth were randomly divided into five groups (10 specimens each): 1) cast metallic post (control group); 2) conventional glass fiber post FibreKor n. 2 (1.25mm diameter); 3) glass fiber post surrounded by glass fiber strips (Interlig); 4) glass fiber post combined with accessory glass fiber posts (Reforpin); 5) anatomic post (glass fiber post covered with low-viscosity composite resin (Filtek Flow). Root canal preparation in the five groups simulated roots with wide root canals and was performed by the step-down technique (two steps). This preparation was performed with a diamond bur n. 1016HL (1.8-mm diameter), which penetrated into the root canal in 10mm (total depth of root canal preparation). The cervical step was prepared with 5-mm depth with a diamond bur n. 3017HL (2.5-mm diameter). Posts were luted with the adhesive system Scotchbond Multi-Uso Plus and resin cement RelyX CRA. After fabrication of the coronal portion of posts (standardized with aid of polypropylene templates) with composite resin Enforce-Core, a metallic full crown cast in nickel-chromium alloy was cemented on it. Specimens were stored in distilled water at 37ºC for 24 hours and submitted to compressive fracture resistance test in a universal testing machine Kratos. Load was applied at 135° to the root long axis, at a crosshead speed of 0.5mm/min. Fracture resistance values were the following, in decreasing order: Group 1 ? 110.85kgf; Group 4 ? 93.88kgf; Group 5 ? 89.34kgf; Group 3 ? 79.07kgf; Group 2 ? 76.04kgf; statistical analysis (ANOVA and Tukey) revealed statistically significant difference (p < 0.05) between groups 1 and 2 and between groups 1 and 3. Concerning the pattern of fracture, all roots in group 1 presented fracture (60% at the middle third); groups 2 and 4 presented 40% of fractures at the cervical root third and 30 to 40% of failure at the coronal portion of the post; group 3 demonstrated predominance of fracture at the cervical root third (60%); in group 5, 50% of failures occurred at the coronal portion of the post

Full textRoot resorption was evaluated in three groups of 70 patients each. The groups consisted of 70 patients without any treatment; 70 patients submitted to orthodontic treatment without root resorption radiographically detectable and 70 orthodontically treated patients with detected root resorption. Dental and maxillary morphology as well as the hormonal, ionic, enzymatic and glycemic profile of all patients were analyzed. The results showed that orthodontically treated and not treated patients presented the same endocrinological conditions. The orthodontically treated group had significantly more triangular roots and more rectangular alveolar crest. According to these results and pertinent literature it was possible to conclude that the occurrence of root resorptions during orthodontic treatment are not a result of systemic alterations, inclusive endocrinopathies. The resorptions due to induced tooth movement are strongly influenced by dental and alveolar crest morphology.

Full textFracture resistance of endodontically treated teeth reconstructed with polyethylene woven fiber ribbon post and cores and dentinal post and cores has been evaluated. For that purpose, 60 human maxillary canines were selected, cut on the cementoenamel junction, endodontically treated (non- filled canal to a depth of 8mm)and fixed in acrylic resin blocks. The specimens were randomly distributed in 4 groups of 15 units each: 1) conventional canal preparation and making of polyethylene woven fiber ribbon post and cores; 2) conventional preparation of canals and dentinal post and cores; 3) fairly flared canals and dentinal post and cores; 4) greatly flared canals and dentinal post and cores. On groups 1 and 2, canals were enlarged as much as number 4 Largo bur; on groups 3 and 4, canals were subjected to standardized sequential cutting to permit a simulation of fairly or greatly flared roots. On group 4, the width of canal walls on the gingival third was 0.5mm. Post cementation was performed with the use of Scotchbond Multi-Purpose Plus bonding agent and Enforce resin cement. The core was built with self-curing composite reinforced with Ti-Core titanium. Specimens were stored in distilled water for 24 hours and subsequently subjected to compression fracture resistance tests on the Kratos universal testing machine until system failure. Load of 100kgf was applied at a speed of 0.5mm/min at an 135° angle in relation to the long axis of the root. Fracture resistance under compression presented the following values (in decreasing order): 1) group 3 58.67kgf; 2) group 2 53.30kgf; 3) group 4 47.91kgf; 4) group 1 45.46kgf. Results were subjected to statistical analysis (ANOVA and Tukey),which only showed significant statistical difference between groups 1 and 3. As to the patterns of failure, the figures observed were: group 1 - 86.6% on the post and/or core; group 2 - 46.6% on the gingival third of the root and an equal figure for post and/or core; group 3 - 40% on the gingival third of the root and 53.3% on the post and/or core; group 4 - 66% on the gingival third of the root and 33.3% on the middle third of the root.

Full textThe cleft lip and palate is a congenital craniofacial malformation characterized by the lip and/or palate not joining. Several consequences can occur from this rupture such as alterations in speech, swallowing, chewing, dental and hearing. As a result of this, these patients need to undergo reconstructive surgeries, and the age it will happen is fundamental for the development of the auditory and orofacial functions to be within expected levels or close to them. There is great relation between the fissure and alterations of the middle ear, having as consequence the momentaneous sensory deprivation, or even the hearing deficiency. Sensory deprivation causes damage to the development of the auditory abilities and sequentially to the language and speech development. In view of what has been stated, the objective of this work was to verify the auditory sustained, divided and selective attention, and phonological awareness ability in children with cleft palate with intervention between the ages of 9 and 12 months. 40 subjects were evaluated, aged between seven and 11 years of age, with cleft palate, without auditory deficiency, who had received primary palatoplasty between the 9 and 12 months of age. We evaluated the auditory sustained, divided and selective abilities, and phonological awareness by means of THAAS, DD, PSI and CONFIAS, respectively. The results were abnormal in 22 (55%), 18 (45%), 13 (32.5%) and three (7.5%) for respective tests THAAS, DD, PSI and CONFIAS. Correlation was found only between PSI, and CONFIAS tests (p=0,02895). We can conclude that higher percentages of performance within expected for age occurred for the tests of auditory divided attention (DD) and selective attention (PSI). The THAAS was the test of auditory attention with bigger alteration. Few patients presented alterations in the test that evaluated the phonological awareness ability.

Full textThe aim of this study was to evaluate the prevalence of Temporomandibular Disorders (TMD) in individuals with and without orthodontic treatment. Sample was composed of 200 individuals divided into four groups, according to the type of malocclusion (Angles Class I or II) and the accomplishment of orthodontic treatment. The presence of signs and symptoms of TMD were evaluated by an anamnestic questionnaire and a clinical examination, including TMJ and muscle palpation, active mandibular range of motion and joint noises. The occlusal examination included analysis of contacts in intercuspal position (IP) and retruded contact position, presence of lateral and anterior guidance and non-working side contacts. Anterior open bite, posterior cross bite, overjet, ovebite, occlusal ajustment and dental attrition were also evalueted. Based on the anamnestic questionnaire, 34% was considered as having mild TMD, while 3.5% had moderate TMD. The presence and severity of TMD have not shown any relationship with type of malocclusion and/or accomplishment of orthodontic treatment. A positive association was found between TMD and absence of anterior guidance. Based on that, it was concluded that orthodontic treatment is not associated with the presence of signs and symptoms of TMD neither occlusion can be defined as a primary etiologic factor for TMD.

Full textThis study evaluated the dentoskeletal and soft tissue changes promoted by the intraoral distalizer Distal Jet, by analysis of lateral cephalograms. The sample was composed of 44 patients, divided into two groups, as follows. Group 1 (study group) was composed of 22 patients, being 5 males and 17 females, with Class II malocclusion, among which 72,72% exhibited ½ Class II, 18,18% ¼ Class II, and 9,09% ¾ Class II. The initial age ranged from 10,54 years to 14,77 years (mean 12,71 years). These patients were treated with the intraoral distalizer Distal Jet for a mean period of 1,20 years. Group 2 (control group) comprised 22 patients, being 13 males and 9 females, aged 11,03 to 14,63 years (mean 12,27 years) at the onset of follow-up, presenting with untreated Class II malocclusion, who were followed for a mean period of 1,18 years. The groups were rendered compatible as to age, period of treatment/observation, severity of malocclusion and initial cephalometric variables. The Student t test for independent samples was applied to compare the initial and final ages, period of treatment/observation, initial cephalometric variables and actual mean changes in the comparison between groups. The severity of malocclusion between groups was analyzed by the chi-square test. The initial and final changes for the study group were evaluated by the t test for dependent samples. The Distal Jet distalizer did not change the anteroposterior positioning of maxilla and mandible, yet promoted an increase in facial growth pattern due to a significant change in mandibular plane angle (FMA). The maxillary first molars exhibited significant distalization, yet did not present statistically significant distal inclination and extrusion. The maxillary second molars presented significant distal inclination, extrusion and distalization. The reciprocal effect of Distal Jet on the anchorage unit promoted significant buccal tipping and protrusion of maxillary incisors, as well as mesialization of the maxillary first premolars, leading to an increased overjet. There were no significant changes in the extrusion of maxillary first premolars and incisors, overbite and facial profile.

Full textSeveral factors have influence on the performance of hearing abilities, spoken language and quality of life of children with cochlear implants (CI). Investigating the multidimensional impact of hearing impairment on the various demands of the child\'s life can help identifying the variables that most influence on results of this population. The achievement of the greatest benefits provided by the use of the electronic device depends on effective insertion in specialized speech therapy and investments in family participation in the auditory habilitation and rehabilitation process. This study aimed to evaluate the quality of life of children with prelingual hearing loss who use cochlear implants and to analyze the correlation with the results of auditory perception of speech, the performance of spoken language and the degree of family permeability in the therapeutic process. Thirty children of both sexes, ranging from six complete years to 12 incomplete years, who use cochlear implants and their respective parents and/or legal guardians participated in the study. The children were evaluated for auditory perception of speech, performance of spoken language, familial permeability and quality of life. The evaluation of hearing abilities showed a statistically significant correlation between the auditory scale Categories Auditory Performance (CAP) and Language Category. In the evaluation of spoken language, no statistically significant results were observed among the studied variables. Familial permeability revealed statistically significant correlations with CAP. From the perspective of parents, CI improved quality of life in all domains related to the child and in one of the domains related to the family. The subscale social relations presented a higher score among the domains. The increase of chronological age had a positive impact on the educational aspects of quality of life. Children with higher hearing categories had an influence on communication and education, and communication was also influenced by language category. Language skills were correlated with the autonomy of children, and parents more permeable to rehabilitation impacted on communication and education. No statistically significant correlations were found between quality of life and age at surgery and hearing age. However, the negative correlation between age at surgery and quality of life suggests that early implanted children tend to have a better quality of life. Therefore, it was concluded that the variable oral language influenced the quality of life in the domains communication and autonomy of the child. The variables auditory performance and familial permeability influenced on quality of life in communication and education domains. Quality of life in the education domain was also influenced by the chronological age of the child.

Full textCurrently implant dentistry has evolved tremendously in the intention of replacing missing teeth, but unfortunately this is not always able, since after tooth loss, in most cases, also the remaining bone is reabsorbed, making it difficult or impossible to install dental implants. This type of bone loss in the jaw or bone loss resulting from surgical resections, are a major concern at present, since the dentists researching bone substitute that restores the shape and contour of the bones of the face and jaws, and/or enabling installation of dental implants. Among the biomaterials, the use of lyophilized bovine bone has become popular and has been gaining ground as it reduces the morbidity of the patient avoiding the removal of autogenous grafts has shown a good and predictable results. In the present study, bone defects were created on the basis of mandible in rabbits, which were grafted blocks lyophilized bovine bone with swines collagen in the experimental groups and control groups left empty. The animals were sacrificed at 0 (immediately after surgery), 3 and 6 months after surgery. The jaws were collected and analyzed using cone beam computed tomography, which analyzed the ability of the graft to aid in bone repair of critical-size defects created in the mandible of rabbits as well as its ability to maintain the contour and shape of the bone. Through the analysis of the tomographic grafted areas was concluded that according to the methodology proposed bovine bone graft with 10% swines collagen was not able to assist in 100% of the bone repair critical size defects created in rabbit jaw, showing a thin layer of soft tissue between the graft and the bed having been efficient space filling of the defect and maintain the bone contour.

Full textThe objective of the present study was to correlate nasalance scores and speech nasality of 79 operated unilateral cleft lip and palate children (males and females), with ages ranging from 4 to 9 years (mean 6.5 years), all speakers of Brazilian Portuguese. All children had already undergone perceptual evaluation of speech nasality, nasometric evaluation, and audio recordings, which took place at the (HRAC-USP).Out of the pré-existed audiorecordings it have been selected to this study the words: \"papai\" and \"bebê\", and the phrases \"Papai pediu pipoca\" and \"O bebê babou\". In spite of the indication that all children had already been judged to present mild, moderate or severe hypernasal speech, speech stimulate which have been audio recorded simultaneously to nasometry were judged again by 3 other experienced speech pathologists. The three speech pathologists were instructed to judge speech nasality. Each speech sample was judged individually by means of a 4 point scale (1 = normal nasality, 2 = mild hypernasality, 3 = moderate hypernasality, and 4 = severe hypernasality). The scores given by the three speech pathologist for the words and phrases varied from 1.0 to 3.3. Considering the cutoff value of 1.5 for perceptual judgements of nasality, 50 (63%) of the children were judged to present means equal 1.5 or below, and 29 (37%) presented means above 1.5 for the word \"papai\". For the word \"bebê\", 46 (58%) presented means equal 1.5 or below, and 33 (42%), means above this value. For \"Papai pediu pipoca\", 42 (53%) presented means equal 1.5 or below, and 37 (47%) means above this value. For the phrase \"O bebê babou\", 43 (54%) of the children presented with means equal 1.5 or below, and 36 (46%) means above this value. The obtained results have also shown that the sensibility of the nasometer to identify hypernasality for the word \"papai\" was 44%, 23% for \"bebê\", 45% for \"Papai pediu pipoca\", and 30% for \"O bebê babou\". With regard to specificity, the results have shown 70% for the word \"papai\", 93% for \"bebê\", 81% for \"Papai pediu pipoca\", and 92% for \"O bebê babou\". The nasalance scores obtained in the present study were 24% for the word \"papai\", 39% for \"bebê, 32% for \"Papai pediu pipoca\", and 39% for O \" bebê babou\". We have concluded in this study that the correlation between nasalance and nasality in a sample of children presenting with speech resonance ranging between normal and mild hypernasality is low, specially when using short speech stimulae with the predominance of only one consonant. We suggest for future studies which aims to correlate nasalance and nasality be designed to use longer speech stimulate with different phonemic context. Besides that the control of possible variables which might influence perceptual judgements of nasality, such as presence of snort, nasal air emission, compensatory articulations should also be considered. We also suggest that the cutoff value for nasalance scores should be established for each sample of individuals, because what might be good for one sample, might not be for another.

Full textThe aim of the present investigation was to evaluate the microleakage of Class II indirect restorations with composed resin Filtek Z250 and cemented with two types of cements: Adhesive Cement Enforce and RelyX Adhesive Resinous Cement. The experimental sample consisted of twenty-four seconds primary molars. Mesiais and distais cavities were prepared in all the teeth and accomplished the procedures to make indirect restorations. After, they were cemented with two types of resinous cements. Soon after that, the specimes were thermocycled, immersed in 0,5% basics fuchsin and sectioned. The microleakage was measured by a software and assessed the dye penetration at the cervical margins. The results were submitted to the analysis by test t dependet. The results demonstrated that none of the tested materials was capable to impede the microleakage completely, and there was no significant differences in relation to the two studied materials.
