Full textOBJECTIVE: Discern the efficacy of panoramic radiography on nasal septum deviation. Gold standard computerized tomography along with clinical examination was used for comparison. MATERIAL AND METHODS: Sample was composed of 70 subjects from Stomatology files of FOB-USP. Nasal septum deviation was assessed using the panoramic radiographies. Then, computerized tomography was analyzed and the results confronted. RESULTS: Images of nasal septum deviation were observed and confirmed in both exams on 100% of the subjects. However, in those cases with no deviation observed with the panoramic radiographies, its presence was confirmed in 86% after computerized tomography. CONCLUSION: Panoramic radiography was trustable for confirmation of nasal septum presence, with 100% of Specificity. Further, this exam allows the confirmation of the absence of this deviation in the majority of cases, with 86% of Sensibility.

Full textObjective: To characterize the nasal geometry of adults with nasal obstruction due to septal deviation and/or turbinate hypertrophy by analyzing sectional areas and volumes of specific segments of the nasal cavity by means of acoustic rhinometry. Design: Prospective study. Setting: Laboratory of Physiology, HRAC-USP and Otorhinolaryngology Clinics, Hospital Estadual Bauru. Participants: Thirty patients with nasal obstruction complaints, of both sexes, aged 18 to 40 years, presenting septal deviation+turbinate hypertrophy (n=24), septal deviation only (n=5) or turbinate hypertrophy only (n=1) on clinical examination. Main Outcome Measures: Sectional areas measured at the three main deflections of the rhinogram (CSA1, CSA2, CSA3), their respective distances from the nostrils (dCSA1, dCSA2, dCSA3) and volumes at the 1.0-3.2cm (V1), 3.3-6.4cm (V2) and 7.0-12.0cm (V3) segments were evaluated, before and after nasal decongestion, by means of an Eccovision Acoustic Rhinometer. For analysis, the values from the right and left cavities were added. Results: Before nasal decongestion, mean values (±SD) obtained corresponded to 0.83±0.23cm2(CSA1), 1.66±0.52cm2(CSA2), 2.36±0.77cm2(CSA3), 2.19±0.20cm(dCSA1), 4.01±0.33cm(dCSA2), 5.85±0.37cm(dCSA3), 2.77±0.51cm3(V1), 6.52±1.99cm3(V2), 26.00±9.62cm3(V3). These values were significantly lower (p<0.05) than those set for adults without obstruction at the same laboratory. Decongestion caused CSA and V increases proportionally higher in the group with nasal obstruction, suggesting the involvement of a functional component. Twelve cases presented normal results, despite the presence of septal deviation and/or turbinate hypertrophy. Conclusion: The results showed, in most patients analyzed, significant impairment of nasal patency associated with nasal obstruction due to structural defects.

Introduction: The purpose of this study was to subclassify the types of facial asymmetries present in a pre-surgical dentofacial deformity patient population to determine the prevalence of each subcategory. Associations between the craniofacial characteristics of each asymmetry and pre-surgical Jaw Pain and Function Questionnaire (JPFQ) scores, diagnosis of temporomandibular disorders (TMD), and posterior facial asymmetry (PFA) as determined by nasal septum deviation were analyzed. In addition, the data will aid in the development of a phenomics database to allow for subsequent genotyping and gene expression evaluation from patient saliva and masseter muscle samples that were obtained at the time of corrective orthognathic surgery. Methods: Pre-surgical posterio-anterior (PA) cephalograms, submentovertex (SMV) and panoramic (PAN) radiographs from 92 pre-surgical dentofacial deformity patients at the Department of Oral and Maxillofacial Surgery, University of Lille, France were collected to evaluate facial asymmetry. PAs were traced and analyzed according to the Grummons Simplified Frontal analysis and Ramal Height analysis (Dolphin Imaging). SMVs were analyzed by the refined clinical system of the Ritucci and Burstone analysis proposed by Arnold et al along with original angular measurements for maxillary, mandibular, and nasal septum deviations (ImageJ). PFA was determined by a nasal septum deviation greater than 15 degrees. Lastly, PANs were evaluated visually for condylar pathologies. A comprehensive diagnostic decision tree for facial asymmetry was formulated based upon the current literature for normal variation of landmarks and the study design. Patient diagnosis via the decision tree was compared to visual examination of the appropriate x-rays to verify accuracy. Using this decision tree, patients were classified into subtypes and prevalence of each was calculated to form a phenomics database for future research on genotyping and gene expression. Associations between the subclassifications, mean pre-surgical JPFQ scores, temporomandibular joint (TMJ) clinical examination results (TMD+ or TMD-), and the diagnosis of posterior facial asymmetry (PFA+ or PFA-) were completed. Results: Sixty-two patients were able to fulfill all radiographic requirements to arrive at a diagnosis. Eighteen patients demonstrated facial asymmetry that fell within normal biological variation while the other 44 were diagnosed as having a form of facial asymmetry – Cranial Base Asymmetry: 11 female, 6 male; Non-Condylar Mandibular Asymmetry: 5 female, 3 male; Hemimandibular Elongation: 2 female, 3 male; Maxillary Asymmetry: 3 female, 1 male; Idiopathic Condylar Resorption: 3 female, 1 male; Atypical Asymmetry: 3 female, 1 male; Hemimandibular Hyperplasia: 1 female, 0 male; and Maxillary Base & Mandibular Body Asymmetry: 0 female, 1 male. JPFQ scores for symmetric patients ((x ) ̅= 5.33) and asymmetric patients (x ̅= 4.57) were non-significant overall, however, differences between gender were noted (female symmetric (x ) ̅= 6.13, male symmetric (x ) ̅= 1.33, female asymmetric (x ) ̅= 5.36, male asymmetric (x ) ̅= 3.19). TMD was diagnosed by pre-surgical TMJ examinations and MRIs. Four symmetric patients (3 female, 1 male) were positively diagnosed with TMD while 14 asymmetric patients (11 female, 1 male) also were diagnosed. PFA was diagnosed when nasal septum deviation was greater than 15 degrees – 25⁰ to ≤35⁰: 9 patients; >35⁰ to ≤45⁰: 3 patients; >45⁰: 1 patient. Twenty patients with a positive PFA were asymmetric while the other 8 symmetric. Twenty-one patients with PFA were female while the other 7 were male. Conclusion: A comprehensive diagnostic decision tree for facial asymmetry classification was formulated and validated. With it, it was found that: Females have increased JPFQ scores and clinical diagnosis of TMD versus males. Asymmetric females have decreased JPFQ scores, but increased prevalence of TMD. Presence of PFA does not appear to be a strong influence on development of facial asymmetry but is significantly linked to the presence of TMD. PFA is present in nearly half of all dentofacial deformity subjects. Mandibular asymmetry is most commonly associated with increased JPFQ scores and presence of TMD. However, Hemimandibular Hyperplasia, a particular and less common form of mandibular asymmetry, never associated with TMD. One form of mandibular and mid-facial asymmetry, Atypical Asymmetry, had a relatively high prevalence of TMD. Future directions for this research include continuation of genotypic description of IGF1 and Nodal biologic pathways to determine how gene expression levels in masseter muscle and patient genotypes differ in the eight subclassifications of craniofacial asymmetry compared to the symmetric population.

Full textINTRODUCTION: The nostril cross-sectional area (bottom of the external nasal valve) presents the first obstacle to airflow. There are doubts and controversies regarding the effectiveness of surgical treatments in this region of the nose during a rhinoplasty. In this study, we have tested two modified strategies for alar reinforcement, one using a cartilage graft from the nasal septum and the other using rib cartilage, to analyze and compare their effectiveness in augmenting nostril cross-sectional area. METHODS: Thirty corpses nostrils were dissected in the Division of Postmortem Inspection at the University of São Paulo. Corpses were chosen at random (9 women and 6 men) excluding those with deforming nasal injury or intra-nasal disease. All nasal septum and rib grafts had the same dimensions (30 x 5 x 1 mm) and were inserted randomly above the lateral crura of the alar cartilages. Then, a total of 90 standardized photographs were taken to measure nostril cross-sectional area using the Autocad® program; one per nostril on all 15 cadavers, at three separate intervals. Thirty photos were taken prior to any procedure being performed, and 60 after the insertion in each nostril, of the two different types of cartilage grafts. After one graft was tested, it was removed and replaced with the other type. The order of the procedures was randomized. Statistical analyses were conducted using a model for repeated measures and ANOVA for the variable area. The comparison of means was done with Tukeys method and a 95% confidence coefficient. RESULTS: The nostril cross-sectional area before treatment, after modified alar reinforcement using septum cartilage graft, and after modified alar reinforcement using rib graft were 0,76 cm2, 0,85 cm2 (increase of 11,8%) and 0,91 cm2 (increase 19.7%), respectively. CONCLUSION: The modified alar reinforcement using grafts of rib cartilage is statistically more effective than the modified alar reinforcement using grafts of nasal septum in increasing the nostril cross-sectional area

Full textThe nasal septum plays a paramount role in the growth of the face and respiratory physiology. Its solidity, its straightness and its sagittal position are determining to perceive a diurnal and night respiratory comfort. Vulnerable to the traumas, the destruction or the inefficiency of its skeleton involves request for a functional and aesthetic repair. In severe cases, the tissue replacement requires large autologous grafts for which the morbidity of the donor site and their own imperfections remain a problem. To replace them, certain biomaterials were tested in an empirical way without giving reliable results. The primary goal of our work was to evaluate the behaviour of a biphasic phosphocalcic implant to repair nasal septum in order to avoid these grafts with an adapted biofunctional implant, exposed to the septic nasal content and the airborne particles of the environment. The second objective was to evaluate the cytotoxicity of the double wall carbon nanotubes on epithelial respiratory cells, first organ concerned by a potential exposure during their manufacture. Thereafter, the results of these two different subjects were used in a synergistic way to answer the third objective which was, to evaluate the influence of the carbon nanotubes on the cicatrization of the nasal septum in presence or not of the phosphocalcic implant

Full textBackground: Nasal anatomical variations can impair the visibility on endoscopic transsphenoidal approach for pituitary tumors. Objective: To evaluate anatomical variations, mainly nasal septum deviation, and their impact on the visibility of transsphenoidal endoscopic approach. To support the decision of access type or need to correct the deviated septum. Methods: Cross-sectional study with 38 patients who underwent transsphenoidal endoscopic surgery using the two nostrils - four hands between February 2009 and January 2011 in a referral center. They were submitted to the intraoperative register of anatomical variations, septal deviations, surgical corridor width and location of the deviated septum (height and depth), depth of the access to sphenoid and sella, exposure of sphenoid and sella after opening. Visibility was assessed using an ordinal scale: 0- no difficulty, 1- low to moderate difficulty, 2- severe difficulty. Comparisons of two means were performed using Students t test, and three or more means using analysis of variance (ANOVA) with Turkeys complementary test. Correlations between scores were analyzed using the non-parametric chi-square test and the likelihood ratio. Results: Seventy-six nasal cavities were studied, and 50 septal deviations were found (66%). Among the patients with severe difficulty, 73% had a surgical corridor width in the location of the deviated septum of up to 9 mm (p < 0.001). Septal deviations in the middle level (p = 0.005) or posterior third (p < 0.001) were associated with severe difficulty. The width of the nasal cavity at the deviation was also smaller in the middle level (8.41 mm, p = 0,012) or posterior third (6.9 mm, p<0.001). In the surgical corridor, only the middle meatus was associated with difficulty (5 to 13 mm, 73% severe difficulty, p = 0.001). Anatomical variations of the nasal conchae were observed in 17% of cases with no impact on visibility. The average length of the nasal septum was 64 mm (95% CI 61.8 -66.8 mm); the mean depth to the sphenoid was 69 mm (95% CI 67-71 mm) and to the sella 82 mm (95% CI 80.2 - 83.8 mm). The average lateral exposure of the sphenoid was 20 mm and anteroposterior 20.8 mm and to the sella 12.8 mm and 11.7 mm respectively. Conclusions: The width of nasal cavity at deviation and site of septal deviation were associated with difficulty in visibility of the access. Septal deviations located at posterior third and at middle level in nasal cavities were strongly associated with difficulty

Full textIntroduction: Nasal obstruction is a symptom present in various nasal diseases. This project proposes to develop a methodology for the calculation of nasal resistance to airflow through computational fluid dynamics and, to compare the results of this technique with those of rhinomanometry. Methods: nasal airflow resistance was measured by rhinomanometry, experimentally and computational fluid dynamics. We investigated the influence of computed tomography segmentation on the computational fluid dynamics variables. The computational model of laminar flow was compared to the kw turbulence model. The accuracy, correlation and agreement between the nasal resistance calculated by computational fluid dynamics was analyzed comparing it with nasal resistance obtained through experiment and rhinomanometry. Results: The nasal resistance provided by computational fluid dynamics can vary up to 50% according to the computed tomography segmentation criteria. The k-w turbulence model showed accuracy of 93.1%, presenting a better performance than the laminar model to predict nasal cavity resistance. The correlation between the flow in 75Pa obtained by rhinomanometry and computational fluid dynamics was high for both cavities, Pearson r >= 0.75 p < 0.001. There was no agreement between nasal resistance provided by the two methods. Nasal resistance due to computational fluid dynamics is, on average, 65% of rhinomanometric resistance. Conclusion: the criteria used for nasal cavity segmentation interfere with the resistance calculated by computational fluid dynamics. The methodology of computational fluid dynamics to calculate nasal resistance was validated experimentally. The turbulent flow model is better than the laminar model to calculate nasal resistance. The nasal resistance calculated by computational fluid dynamics showed a high correlation with the measurement by active rhinomanometry, but the level of agreement between the methods does not allow a direct comparison between the values obtained by each one

Full textObjective: To analyze the effects of rhinoseptoplasty on the nasal cross-sectional areas and volumes, and the speech nasalance of individuals with repaired unilateral cleft lip and palate, assessed by acoustic rhinometry and nasometry. Design: Prospective analysis. Setting: Surgery Service and Laboratory of Physiology at the Hospital for Rehabilitation of Craniofacial Anomalies (HRAC-USP). Participants: Individuals with previously repaired unilateral cleft lip and palate (n=21, age=15-46 years) were evaluated before surgery (PRE) after 6-9 months (POST1) and after 12-18 months (POST2). Variables: Acoustic rhinometry was used to measure the cross-sectional areas of segments corresponding to the nasal valve (CSA1), anterior portion (CSA2) and posterior portion (CSA3) of the lower turbinate, and the nasal volumes at the regions of the nasal valve (V1) and nasal turbinates (V2) at both sides, before and after nasal decongestion with a topical vasoconstrictor. Nasometry was employed to evaluate the speech nasalance during the reading of a text predominantly containing nasal sounds and other containing only oral sounds. Results: At the cleft side, before nasal decongestion, there was a significant increase (p<0.05) in mean CSA1 and CSA2 values at POST1 and POST2 compared to PRE. After decongestion, increased values were also observed for CSA2 and V2 at POST2. No significant changes were observed at the non-cleft side. The mean nasalance values at PRE, POST1 and POST2 were not different from each other in both oral and nasal texts. Conclusion: The measurement of cross-sectional areas and volumes by acoustic rhinometry revealed that rhinoseptoplasty provided, in most cases analyzed, a significant increase in nasal patency, without concomitant changes in speech resonance, as estimated by nasalance assessment.

Full textThe Surgically assisted rapid palatal expansion (SARPE) is a surgical procedure indicated for the correction of maxillary constriction in adult patients. The effects of EMCA are observed not only in dental, maxillary, and mandibular arches, but also in the nasal cavity, since the septum is located in the center of the nasal floor and rests on the median palatine suture. The purpose of this study the position of the nasal septum before and after surgical separation of the maxillary, was to identify and evaluate their influence on the movement of the jaw which remained attached. Fifty six cone beam computed tomography (CBCT) scanner acquired i-CAT Classic, with 0.3 mm voxel. Fourteen individuals submitted to SARPE in the preoperative and postoperative periods of 15, 60, and 180 days which were evaluated. Initially, postoperative images were visualized using multiplanar reformatting to identify which jaw, right or left, the nasal septum remained bound after the SARPE. In a second step, linear measurements in the images corresponding to the pre- and postoperative periods were performed. These measurements were performed in the axial immediately above the expander reformatting, standardized form for each patient, and consisted of the distance from a central reference line, passing the anterior nasal spine and the center of the incisive foramen, dividing the patient\'s right side and left to the canines and molars on the right and left. The intraobserver kappa index was > 0.9. To compare the differences between the means of two groups (side connected to the nasal septum and not connected to the nasal septum) a t test was used. In 78.6% of patients, the nasal septum remained attached to the left maxilla and 21.4% on right jaw. Regarding linear measurements, both in the region of canines as in the molar region, it was observed that, in the preoperative period, there was no difference between the right and left sides. After the SARPE, a statistically significant difference (p < 0.05) was observed, noting that there was less movement of the maxilla which the nasal septum remained connected. Therefore, it can be concluded that the expansion jaw is asymmetrical because the jaw remains on the nasal septum after SARPE and moves less than maxilla not connected to the nasal septum.

Full textTiivistelmä Korva-, nenä- ja kurkkutautien (KNK) kirurgia tähtää useimmiten elämänlaadun (EL) parantamiseen. EL:n huomioinnin yleisyys näyttöön perustuvien tietokantojen sisältämissä tutkimuksissa ei ole tiedossa. Primaareissa nenäleikkauksissa EL:n tulokset, ennustekijät ja eri mittareiden käytettävyys kaipaavat lisätietoja. Tarkoituksena oli 1: Tutkia systemaattisella kirjallisuuskatsauksella miten nykyiset Cochrane-suositukset huomioivat EL:n. 2: Tutkia primaarin nenäkirurgian vaikutus EL:uun, tunnistaa EL:n ennustekijöitä ja vertailla eri mittareita. Yhteensä 160 primaariin nenän väliseinäleikkaukseen (VL) tai sivuonteloiden tähystysleikkaukseen (ESS) tulevaa aikuista ja 206 ikä- ja sukupuolivakioitua verrokkia osallistui etenevään kaltaistettuun kohorttitutkimukseen vv. 2010-2014. EL mitattiin tautispesifillä Sino-Nasal Outcome Test -22:lla (SNOT–22) ja yleisellä RAND–36:lla ennen leikkausta ja 12 kk leikkauksen jälkeen. Kolmantena mittarina käytettiin taannehtivaa Glasgow Benefit Inventoryä (GBI). Cochrane-tietokannan yleisimpien KNK-leikkausten tutkimuksista 10 %:ssa (3 30:stä) sisälsi EL-tuloksia. Vuoden 2000 jälkeen EL:n käyttö on lisääntynyt. SNOT–22 kokonaispistemäärä parani VL- ja ESS-ryhmissä lähes kontrollien tasolle, VL-ryhmässä (N=64) 34.9:stä 19.1:een ja ESS-ryhmässä (N=70) 35.1:stä 19.3:een. Kontrollien SNOT–22 oli alussa 17.7 ja seurannan jälkeen 15.3. Myös RAND–36 ja GBI paranivat leikkauksen jälkeen. Monimuuttuja-analyysissä hyvän EL-tuloksen paras ennustetekijä oli korkea leikkausta edeltävä SNOT–22 sekä VL- että ESS-ryhmissä (vakioitu vetokertoimien suhde 10; 95 % luottamusväli 1.6–64 ja 12; 2.5–55, ryhmittäin). ROC (receiver operating characteristic) -käyräanalyysissä leikkausta edeltävä arvo 30 antoi parhaan herkkyyden (74 %) ja tarkkuuden (70 %). GBI vaikutti herkimmältä aistimaan muutoksen, mutta mittarit olivat samaa mieltä vain noin 10%:ssa niistä potilaista, joilla oli huonoin EL ennen leikkausta tai paras tulos leikkauksen jälkeen. Tulosten mukaan Cochrane-tietokannassa olevat KNK-tautien kirurgian tutkimukset ovat ottaneet harvoin elämänlaadun huomioon. Nenän väliseinän vinous ja toistuva äkillinen tai krooninen sivuontelotulehdus laskivat EL:ua. Näiden tautien primaarikirurgia paransi EL:n lähes samalle tasolle kuin kontrolliryhmällä. Korkea leikkausta edeltävä SNOT–22 –kokonaispistemäärä ennusti parhaiten hyvää tulosta. Eri EL-mittarit tunnistivat eri potilaat, jotka hyötyivät parhaiten leikkauksista

Full textContext : Oxytocin (OT) and vasopressin (VP) modulate social behaviors. The roles of OT and VP have been interrogated so far in isolation whereas combinatorial effects are anticipated as both hormones are secreted during social behavior. In the lateral septum (LS), a brain area processing behavioral social cues, OT and VP are released during social interaction and modulate social recognition or discrimination. Aim : To understand the dual function of OT and VP during social behavior in physiological and pathological conditions. Methods : In male mice, we used electroencephalographic (EEG) activity as a readout to characterize OT and VP dependent electrophysiological signatures and their sequence. We manipulated OT and VP systems to LS during social recognition/discrimination paradigm using pharmacology and optogenetic tools. Using slice electrophysiology, we characterized electrophysiological responses of LS neurons to both of these hormons.Results : Measurement of EEG theta activity allowed us to discriminate between OT and VP dependent LS modulation and indicated that VP would be released in the LS during 1st encounter with a juvenile while OT would be released during the habituation process. Modulation of OT and VP actions on the LS demonstrate that V1a activation during 1st encounter is essential for social discrimination and OT receptor activation during the habituation process allows the regain of interest for a new juvenile. We also demonstrated that OT and VP modulate electrical activity of almost all LS neurons. The nature of this modulation define 3 neuronal categories that communicate with each other through GABAergic signalling. Magel2KO mouse, which features social deficits, presents an altered balance of LS regulation by OT and VP. It suggests that this regulation could be involved in some pathological symptomatology.Conclusions : These results shed a light on the necessity to study vasopressin along with oxytocin. Doing this, we showed that vasopressinergic and oxytocinergic activation of the LS are sequentially important during the social recognition paradigm. Futhermore, this sequence of events is impaired in a mouse model featuring deficits of OT and social disabilities

O aumento da sobrevida de neonatos prematuros tem sido proporcionado pelos avanços tecnológicos, destes, a ventilação com pressão positiva contínua com prongas nasais constitui alternativa para neonatos com problemas respiratórios. Contudo, evidências científicas mostram ocorrências de lesões nasais pelo uso de prongas. Nesse contexto, esse estudo objetiva avaliar a incidência e os fatores de risco associados à lesão de septo nasal em neonatos prematuros utilizando prongas nasais reutilizadas e novas. O estudo é do tipo coorte de intervenção terapêutica aberta, a população inclui neonatos com idade gestacional abaixo de 37 semanas admitidos na unidade neonatal de um hospital universitário do Recife-PE, Nordeste do Brasil. A amostra foi de 70 neonatos, divididos no grupo de expostos, 39 recém-nascidos utilizando prongas nasais reutilizadas e não expostos, 31 utilizando prongas novas. Os dados foram coletados em prontuários, para caracterização da amostra; pela utilização de instrumentos voltados à avaliação da aplicação da ventilação não invasiva e assistência de enfermagem aos neonatos em uso de prongas; e pela avaliação do septo nasal. O processamento e análise foram realizados pelo software SPSS versão 17.0. Como produtos dessa dissertação foram elaborados três artigos. O primeiro artigo “Prevenção de lesão de septo nasal em neonatos pré-termo em uso de prongas nasais: revisão integrativa da literatura” investigou as evidências científicas relacionadas aos cuidados de enfermagem na prevenção de lesão de septo nasal em prematuros. Os resultados mostraram aspectos da qualidade e adequação da pronga nasal e a necessidade de monitorização do neonato pela equipe de enfermagem. O segundo “Cuidados de Enfermagem ao prematuro na prevenção de lesões nasais: validação de instrumento” validou um instrumento voltado à prevenção de lesão nasal obtendo índice de concordância de 80% dos juízes. O terceiro constitui o artigo original “Lesão de septo nasal em neonatos pré-termos no uso de prongas nasais”, cujos resultados evidenciaram que 62,9% dos neonatos apresentaram lesão de septo nasal e que a associação de prongas nasais reutilizadas e novas não constituiu fator de risco para a ocorrência de lesões nasais. O tempo de permanência do neonato no uso da ventilação não invasiva com prongas foi o único fator associado à ocorrência e severidade dessas lesões. Infere-se que os cuidados de enfermagem na aplicação da terapêutica e no acompanhamento diário dos prematuros em uso de pronga realizados durante o estudo, possam ter minimizado a incidência das lesões nos neonatos. A educação em saúde no serviço pode contribuir para adequação das práticas de cuidados de enfermagem garantindo assistência de qualidade.

Full textIntroduction: The effects of inferior turbinate reduction during rhinoseptoplasty are unknown. Data evaluating the results of rhinoseptoplasty through quality of life outcomes are scarce. Main objective: To evaluate the effects of inferior turbinate reduction during primary rhinoseptoplasty on quality-of-life outcomes and nasal airway cross-sectional area. Secondary objectives: 1) To correlate objective measures of nasal cavity area, as measured through acoustic rhinometry, with subjective measures of quality of life related to nasal obstruction; and 2) To assess surgical outcomes of patients who underwent vertical division of domus for nasal tip refinement using specific quality of life instruments. Design: Randomized clinical trial. Subjects: Individuals over 16yr with nasal obstruction, eligible to functional and aesthetic rhinoseptoplasty. Intervention: Rhinoseptoplasty with or without inferior turbinate reduction. Outcomes: Relative change ([postoperative – preoperative] / preoperative score) on the following instruments: Nasal Obstruction Symptom Evaluation in the Portuguese language (NOSE-p), a quality-of-life instrument specifically related with nasal obstruction symptoms; Rhinoplasty Outcomes Evaluation (ROE), specifically designed to assess rhinoplasty results; a general quality-of-life instrument, World Health Organization Quality of Life Instrument-bref (WHOQOL-bref); nasal obstruction visual analogue scales; and nasal area measurements in acoustic rhinometry. Outcomes were blindly assessed 3 months postoperatively. Results: 50 patients were included, mainly Caucasians with moderate/severe allergic rhinitis symptoms. Mean age was 32 ± 12 yr, and 58% were female. Rhinoseptoplasty improved specific and general quality-of-life scores, irrespective of inferior turbinate surgery (P < 0.001). There was no difference between subjects submitted or not to turbinate reduction in NOSE-p scores (-75% vs. -73%; P = 0.893), in any of the WHOQOL-bref score domains (P > 0.05), and in acoustic rhinometry recordings (P > 0.05). Multivariable analysis, adjusted for postoperative topical corticosteroid use and previous nasal fracture, had no effect on these results. Fewer patients in the inferior turbinate reduction group were using topical corticosteroids 3 months after surgery (6 [24%] vs. 13 [54%], P = 0.03). There was no significant correlation between NOSE-p scores and acoustic rhinometry recordings (ρ = 0.054-0.247; P > 0.05). Among patients undergoing vertical dome division (n=44), mean postoperative ROE, NOSE-p and VAS scores improved significantly in postoperative evaluation (76 ± 17, 23 ± 18 and 78 ± 21) when compared to preoperative scores (30 ± 17, 74 ± 21 and 20 ± 24 respectively; P < 0.001). Conclusion: 1) Turbinate reduction during primary rhinoseptoplasty did not improve short-term general and specific quality-of-life outcomes and acoustic rhinometry recordings; the role of turbinate reduction in sparing chronic corticosteroid use should be confirmed in long-term follow-up studies. 2) The size of the nasal cavity and quality-of-life scores are not correlated and these measures may assess different aspects of the nasal airway. 3) Vertical dome division for nasal tip refinement resulted in short-term significant improvement of specific quality-of-life outcomes.

Only 32% of the population of Natal is attended by sewage, while the remaining population use pits and septic tanks. The characterization of the contents of septic tanks and pits contributes to the performance of such system and may guide the decision on treatment of these contents. The main of this research is to characterize the contents of interior residential pits and septic tanks in the greater Natal, with the following specific goals: to develop and manufacture a sampler capable of collecting a representative sample of the entire column (the surface scum, the clarified liquid and sludge bottom); to compare the contents of the tanks with the pits; to compare the contents of the septage from vacuum trucks; to relate the composition content with socioeconomic characteristics of households; to compare the content in both chambers of the septic tanks in series; to assess the situation of the content before and six months after the cleanness; and ultimately propose a pilot scale plant for treatment of septage. Once the sampler was developed, samples were collected within 14 septic tanks and 10 pits in many districts of Natal. Medians of the 24 systems were obtained: temperature, pH, conductivity, oil and grease, total solids, total suspended solids and sediments of 28.0 ?C, 6.95; 882 mS/cm, 75.2 mg/L; 10,169 mg/L, 6,509 mg/L and 175 mL/L respectively; 111.0 mgN/L for ammonia, 130.5 mgN/ L for organic nitrogen, 0.2 mgN/L for nitrite, 0.4 mg/L for nitrate; 8935 mgO2/L for COD, 29.2 mgP/L for total phosphorus, thermotolerant coliforms from 9.95 E +06 CFU/100mL helminth eggs and 9.2 eggs/L with a maximum concentration of 688 eggs/L and minimum of 0 eggs/L. Medians of organic nitrogen and TKN were significantly different between groups of tanks and pits. The systems with cleanness gap from 11 and 20 years presented the higher concentrations for most variables. The effluent from the toilets and bathrooms participate more effectively in contributing fractions of solids, alkalinity, nitrogen, COD, total phosphorus, thermotolerant coliforms and helminth eggs. The systems used by socioeconomics class with income from R$ 3,700.00 to R$ 7,600.00, presented higher concentrations for COD, nitrogen, solids and helminth eggs. The first of the two chambers had always presented higher concentrations over the second compartment. The analysis of variance for most variables, showed that the values of septic tanks, pits and septage from vacuum trucks belong to the same group. In the samples taken after cleanness, the median of pH and temperature increased, while alkalinity, COD, organic nitrogen, total phosphorus, ammonia and helminth eggs decreased. The oils and greases and thermotolerant coliforms had slightly varied due to the continuous release of sewage into the systems that maintained their steady state concentrations.
Apenas 32% da popula??o de Natal ? coberta por rede coletora de esgotos, sendo as fossas e tanques s?pticos os mecanismos de disposi??o de esgotos comumente utilizados pelo restante da popula??o. A caracteriza??o do conte?do de fossas e tanques colabora para o conhecimento sobre o tratamento desses res?duos no pr?prio domic?lio, al?m de enriquecer as informa??es a respeito deste conte?do. O objetivo geral desta pesquisa ? caracterizar o conte?do do interior de fossas e tanques s?pticos residenciais da cidade de Natal, tendo como metas espec?ficas desenvolver e fabricar um amostrador capaz de coletar uma amostra representativa de toda a coluna dos tanques s?pticos e fossas, que contemple a escuma da superf?cie, o l?quido clarificado e o lodo presente no fundo; comparar o conte?do dos tanques com os das fossas; comparar o conte?do com os res?duos dos caminh?es limpa-fossa; avaliar a composi??o do conte?do e relacionar com as caracter?sticas s?cio-econ?micas dos domic?lios; comparar a qualidade do conte?do nas duas c?maras dos tanques s?pticos em s?rie; avaliar a situa??o do conte?do antes e decorridos seis meses ap?s o esgotamento e, por fim, propor uma esta??o, em escala piloto, para o tratamento dos res?duos gerados por tanques s?pticos e fossas. Com o amostrador desenvolvido foram coletadas amostras do interior de 14 tanques s?pticos e 10 fossas em bairros de Natal. O conte?do dos 24 sistemas obteve medianas para temperatura, pH, condutividade el?trica, ?leos e graxas, s?lidos totais, s?lidos suspensos totais e sediment?veis de 28,0?C; 6,95; 882 mS/cm; 75,2 mg/L; 10.169 mg/L; 6.509 mg/L e 175 mL/L respectivamente; 111,0 mgN/L para am?nia, 130,5 mgN/L para nitrog?nio org?nico, 0,2 mgN/L para nitrito, 0,4 mg/L para nitrato; 8.935 mgO2/L para DQO, 29,2 mgP/L para f?sforo total; coliformes termotolerantes de 9,95E+06 UFC/100mL e ovos de helmintos 9,2 ovos/L com concentra??o m?xima de 688 ovos/L e m?nima de 0 ovos/L. Houve diferen?a estat?stica significativa para nitrog?nio org?nico e NTK entre os grupos dos tanques e fossas. A classe com tempo de esgotamento entre 11 a 20 anos apresentou para a maioria das vari?veis concentra??es bem mais elevadas. O efluente oriundo dos banheiros e sanit?rios participou mais efetivamente na contribui??o das fra??es dos s?lidos, alcalinidade, fra??es nitrogenadas, DQO, f?sforo total, coliformes termotolerantes e ovos de helmintos. A classe com renda entre R$ 3.700,00 a R$ 7.600,00, apresentou maiores concentra??es para DQO, nitrog?nio, s?lidos e ovos de helmintos. A primeira c?mara dos tanques s?pticos de duas c?maras em s?rie apresentou conte?do mais concentrado em rela??o ao segundo compartimento. Nas an?lises de vari?ncia a maioria das vari?veis apontou que os valores de fossas, tanques s?pticos e res?duos de carros limpa-fossa pertencem ao mesmo grupo. Na amostragem ap?s o esgotamento, o pH e temperatura aumentaram suas medianas, enquanto que alcalinidade, DQO, nitrog?nio org?nico, f?sforo total, am?nia e ovos de helmintos diminu?ram. Os ?leos e graxas e coliformes termotolerantes variaram pouco devido ao lan?amento cont?nuo de esgoto dentro dos sistemas que mantinham suas concentra??es est?veis

Full textObjectives/Hypothesis: To evaluate the impact of endoscopic partial inferior turbinectomy (EPIT) associated with primary Rhinoseptoplasty on quality of life outcomes (QOL), complications, and surgical duration. Study Design: Randomized clinical trial. Methods: Individuals with nasal obstruction aged ≥ 16 years who were candidates for functional and aesthetics primary Rhinoseptoplasty were evaluated from March 2014 through May 2015 at a tertiary university hospital in Brazil. Eligible participants were randomly allocated to rhinoseptoplasty with or without EPIT. Outcomes: Absolute change (postoperative –preoperative) in the following QOL scores: Nasal Obstruction Symptom Evaluation-Portuguese (NOSE-p), Rhinoplasty Outcome Evaluation (ROE) and World Health Organization Quality of Life (WHOQOL)-bref (to measure general QOL). Outcomes were blindly assessed 3 months postoperatively. The protocol was registered at ClinicalTrials.gov (NCT02231216). Results: Fifty patients were studied. Most were Caucasian and had moderate/severe allergic rhinitis symptoms. Mean age was 36 (±14.5) years. Rhinoseptoplasty was associated with improvement in all QOL scores irrespective of turbinate intervention (P <0.001). ANCOVA was conducted to control for potential confounders. There was no difference between the groups in absolute score changes for NOSE-p (-50.5 vs. -47.6; P=0.723); ROE (47 vs. 44.8; P = 0,742), and all WHOQOL-bref score domains (P >0.05). There were no differences between the groups regarding presence of the complications. Surgical duration was higher in the EPIT group (212 minutes ± 7.8 vs. 159.1 ± 5.6; p ˂ 0.001). Conclusions: Turbinate reduction through EPIT during primary rhinoseptoplasty did not improve short-term general and specific QOL outcomes. The use of EPIT increases surgical time considerably without improving QOL scores. There was no difference in postoperative incidence of complications, suggesting that EPIT is a safe technique.

This study entitled “Three-dimensional Reconstruction System of Intelligent Automatic Detection of Nasal Vestibule and Nasal Septum in Computed Tomography Images” attempted to combine the image processing technology to capture the computed tomography image signal and the back-propagation network for the automatic capturing of the nasal vestibule and nasal septum areas in computed tomography images. Moreover, it reconstructed the three-dimensional images by combining the two areas with skull and nose to measure the three-dimensional information. The present medical diagnosis often relies on computed tomography images to manually select the areas for reference, and use the software to conduct the three dimensional reconstruction measurement of the selected area for the reference of the pre-operational judgment. Therefore, this study developed a three-dimensional reconstruction system of intelligent automatic detection of nasal vestibule and nasal septum in computed tomography images. The proposed system employs the image processing technology combined with back-propagation network to segment the nasal vestibule and nasal septum areas, and mark each computed tomography image individually for the three dimensional reconstruction of the nasal vestibule and nasal septum areas. Finally, the representative points of three operational risky areas, including brain, eye rim internal side and the eye rim lower edge, were marked in order to measure the distance between intranasal information and marked points. The system could assist doctors in pre-operation analysis and judgment with more nasal information to reduce errors caused by human factors. The overall detection rate of the proposed three-dimensional measurement system of intelligent automatic detection of nasal vestibule and nasal septum in computed tomography images reached 99.7%. The three-dimensional image presentation combined with the skull and nose has been confirmed by doctors of the Department of Otolaryngology - Head and Neck Surgery, at Tri-Service General Hospital as valuable in reference. The study findings can facilitate the pre-operation diagnosis and judgment of doctors, as well as help to improve medical quality and the development of the medical industry.

Abstract In the study, effects of concentration of bovine pituitary extract and composition of polyglycolide (PGA)poly(lactide-co-glycolide) (PLGA) 85/15 scaffolds on chondrocytes culture were investigated. Bovine pituitary was broken to pieces by using duall tissue grinder, and was purified and concentrated to obtain pituitary extract, which was added into the culture system of chondrocytes. Pure PGA or PLGA 85/15 microcarriers with diameters of about 400 m were put into spinner flasks with primary chondrocytes for 12-day suspension culture by 60 rpm. Porous cylindrical scaffolds composed of various PGAPLGA compositions with diameter of about 7.5 mm and height of about 2.5 mm were prepared by solvent castingparticulate leaching method. 4.5´106 cells/ml was seeded into each scaffold by direct injection, and the scaffold was fixed by cotton wires in spinner flasks to proceed 28-day suspension culture. Another 28-day culture was proceeded with various porosities of scaffolds with coating of 0.1 collagen type I or 0.1 human fibronectin. Experimental results showed that the rate of chondrocytes growth for PGA microcarrier is faster than that for PLGA microcarrier. Chondrocytes density, and excretion of glycosamino- glycan and type II collagen increased with the concentration of pituitary. The higher the percentage of PGA in scaffolds, the better the environment for chondrocytes growth. Appearance of cells is approximately spherical shape. High porosity of scaffolds is beneficial to the chondrocytes growth. However, coating of collagen type I or human fibronectin has no obvious advantages to the chondrocytes growth.

The anterior medial gland (AMG) is located in the submucosa of the respiratory portion of the mammalian nasal septum. In rodent, AMG is characterized by the presence of four to five parts and each part consists of a long main duct connecting to the striated duct and intercalated duct on which numerous acini studded. Excluding the second of rat or third of gerbil main duct, which opens into the vestibule, other main ducts open into anterior respiratory portion of nasal septum. A major function of the AMG is suggested to provide fluid for humidification of inspired air. Due to the tremendous variation in the environmental air humidity, on which rats and gerbils depend to live, we expected that multiplicity or variation on ultrastructure and histochemistry of AMG acinar cells does exit in these two species. The present study, therefore, attempts to differentiate the morphology and histochemical properties of the AMG between gerbils and rats. A total of 40 male rats (16-24wk old, 400g b.w.) and 40 male gerbils (16-24wk old, 75-90g b.w.) were used in the present study. After cardiovascular perfusion with fixatives, AMGs were dissected out and divided into anterior, medial and posterior portions. Ultrastructure of acinar cells was examined by electron microscopy. Various lectins, including DBA (Dolichos biflorus), UEA (Ulex europeus), WGA (Triticum vulgaris), Con A (Concanavalin A), etc., were applied to assess the glycoconjugates content of the acinar cells at light microscopic level. The major differences on the ultrastructure of rat and gerbil AMG acini cells were: (1) The nucleus of rat AMG acini cells was irregular in shape, but that of gerbil is round or elliptical; (2) Secretory granules of rat AMG acini cells contained homogenous content with various electron density and can be divided into three type: high, low and moderate electron density secretory granules, while the gerbil has only two types of granules with either internal lamellar structure or vesicle assembly; (3) Mitochondria distributed among the compactly and parallel arranged rER in rat AMG acinar cells; but they were distributed randomly in the cytoplasm of gerbil AMG acinar cells; (4) Myoepithelial cells are present in acinar cells of medial and posterior portion of AMG of rat; but not in gerbil; (5) Nerve terminals were demonstrated in the medial and posterior portion rat AMG while nerve terminals were observed through all of the gerbil AMG. Lectin histochemistry indicated that: (1) Acinar cells, from either rat or gerbil AMG, showed no reactivity toward UEA and expressed strong reactivity toward Con A; and (2) Varying degrees of reactivity toward different lectins, including DBA, PNA and SBA, were recognized in both rat and gerbil AMG acinar cells. All these results suggested that acinar cells of AMG express different affinity toward different lectins and that abundant mannose residues exist in the cytoplasm of acinar cells.

Full textTratamentos cirúrgicos para a obstrução da via aérea nasal são comuns na prática em otorrinolaringologia. A cirurgia do septo nasal é a terceira cirurgia mais realizada em ORL nos Estados Unidos da América. É uma técnica que se tem sofrido alterações nos últimos dois séculos, nos quais foram derrubados muitos dos obstáculos inerentes à mesma. Elaborou-se esta revisão de forma a rever quais foram os avanços ao longo do tempo, que opções existem nos dias de hoje, tentar perceber quais são alguns dos próximos passos e qual o rumo a seguir no futuro. A técnica endoscópica melhorou bastante os resultados por meio de uma identificação mais exata da patologia, minimizar o risco hemorrágico intraoperatório, bem como representar uma ótima ferramenta pedagógica. No futuro, as indicações para Tomografia Computorizada dos seios perinasais podem alargar com o avanço da técnica de baixa radiação, bem como a redução de custos da mesma. A cirurgia do septo nasal evoluiu bastante ao longo dos anos com o aparecer de variadas técnicas. Continua, no entanto, a ser um procedimento desafiante para o otorrinolaringologista. Não há um plano único que sirva todos os doentes. É essencial uma boa avaliação da localização e gravidade das alterações e planear caso a caso.
Surgical treatment for Nasal airway obstruction are common practice in otolaryngology. The surgery of the nasal septum is the third most performed in otolaryngology, in the USA. This technique has changed over the last two centuries, in which many obstacles were tackled. An article review was carried out in order to revisit the advances through time, what options are available today, try to understand some of the next steps and what is the course for the future. Endoscopy was a major improve for the results due to a more exact identification of the pathology, minimizing the intraoperatory hemorragic riscs, and stand as a prime teaching tool. In the future, the indication for the perinasal sinus computorized tomography can widen with the enhancement of the low dose radiation technique, as well as the costs of it. The surgery of the nasal septum has evolved a lot through the years, and with the advent of many techniques. It still remains challenging for the otolaryngologist. There is no sigle plan that suits every patient. A good evaluation of the location and severity of the deviation is essencial, as well as planning each case individually.

This article aims to systematize the literature regarding this technique, describing its indications, types of approaches and variations of the procedure and also its complications and outcomes.

Full textThe external nose, nasal cavity, and paranasal sinuses represent key structures whose normal functions may be impaired by several variations and diseases of the upper respiratory tract. Nevertheless, its study in past populations has been neglected. The main aim of the current study is to investigate systematically the osseous changes affecting the sinonasal anatomy of the human skull, as well as its possible impact on craniofacial morphology. Three identified osteological collections from Coimbra and Lisbon comprising 2024 individuals (males=52.7%, females=47.3%; mean age at death=47.81), who lived between 1804 and 1981 were studied. New macroscopic methodologies were structured for recording paradoxical curvatures of the middle turbinate, nasal septal deviations, and spicules on the middle turbinate, whilst computed tomography scanning was used to complement the differential diagnosis. Nasal trauma was recorded in 8.4% (148/1770) of the individuals and the higher frequency in males shows statistically significant differences. The increased age at death also plays a statistical significant role in individuals presenting nasal fracture. A lateral impact force trauma was recorded in 61.5% (91/148) of the individuals, whilst 12.8% (19/148) show other fractures on the facial skeleton. Although the differential diagnosis is limited by the nonspecific location of nasal and facial fractures concerning blows and falls, frequency of lateral impact shows that interpersonal and intimate partner violence may have played an important role in males and females, respectively. The five nasal variations investigated presented prevalence of 38.5% (hypertrophy of the middle turbinates), 50.5% (paradoxical curvature of the middle turbinates), 17.9% (accessory turbinates), 94.8% (septal deviations), and 14.2% (septal spurs), showing that all are fairly common. The nasal septal deviation index and septal spurs present a higher frequency in males, with statistically significant differences. The fact that adult age does not play a significant role in the presence of the nasal variations studied shows that its development may have occurred during early age and is consistent with the hypothesis that genetics may play an important role in their presence. New bone formations on the middle turbinates and within the maxillary sinuses show prevalence of 59.3% and 49.8%, respectively, both showing statistically significant sexual differences with higher frequency in females. Clinical and palaeopathological literature confirm that these osseous alterations are highly consistent with rhinitis and chronic maxillary rhinosinusitis. The high prevalence of bone formations in both anatomical structures may be related to several reasons, including being the first line of defence against numerous external aggressions, indoor (e.g., smoke due to unprocessed biomass fuels burnt during cooking) and outdoor (e.g., industrialisation) air pollution, insalubrity and lack of hygienic conditions, or mucociliary dysfunction. Clinical studies also state that the nasal anatomical variations may play an important role in sinonasal disease. In the present study, hypertrophy and paradoxical curvature of the middle turbinates are statistically associated with the presence of spicules in the same osseous structure, whilst none of the variations studied are associated with the presence of bone formations within the maxillary sinuses, which is in accordance with most of the clinical literature. Also, although several factors may have played a role on sinonasal disease in the same individual, their relative importance is impossible to study in skeletal remains. The presence of concha bullosa and maxillary rhinosinusitis suggests an effect on craniofacial morphology, since six measurements and two indices revealed a pattern of increased facial breadth in individuals presenting those osseous alterations. This may be related to the development of both concha bullosa and maxillary rhinosinusitis during growth of the facial and cranial bones and anatomical structures, playing a role in its development. Finally, a miscellaneous of osteoblastic and osteoclastic bone alterations was observed on the anatomical structures studied. New cases consistent with leprosy and the first known evidence of possible teaching of modern dacryocystorhinostomy were discussed. The current work brings a new perception of sinonasal morphology and disease in past populations, showing that its presence was frequent in Portugal during the 19th and 20th centuries. Simultaneously, new methodological approaches are expected to facilitate future research understanding sinonasal morphology and disease and its impact on human life.
O nariz externo, cavidade nasal e seios paranasais são estruturas chave cujo normal funcionamento pode ser dificultado por diversas variações e doenças do trato respiratório superior. O seu estudo em populações do passado tem sido, no entanto, negligenciado. O presente trabalho tem como objetivo principal o estudo sistemático das alterações ósseas que afetam a anatomia sinonasal do crânio humano, assim como o seu possível impacto na morfologia craniofacial. Três coleções osteológicas identificadas provenientes de Coimbra e Lisboa que incluem 2024 indivíduos (sexo masculino=52,7%, sexo feminino=47,3%; idade à morte média=47,81) que viveram entre 1804 e 1981 foram estudadas. Novas metodologias macroscópicas são descritas para o registo da curvatura paradoxal, do desvio do septo nasal e de espículas ósseas na concha nasal média. Foi também utilizada a tomografia axial computorizada como meio complementar de diagnóstico diferencial. O trauma nasal foi registado em 8,4% (148/1770) dos individuos que fazem parte da base de estudo e a maior frequência no sexo masculino representa diferenças estatísticas significativas, assim como o aumento da idade à morte nos indivíduos que apresentam fratura nasal. A maior parte destes indivíduos (61,5%, 91/148) evidencia o resultado provável de uma força de impacto lateral, enquanto 12,8% (19/148) apresentam outras fraturas no esqueleto facial. Apesar do diagnóstico diferencial destas lesões ser limitado pela localização não específica das fraturas identificadas tendo em conta a sua origem violenta ou não violenta, a frequência da força de impacto lateral mostra que a violência interpessoal e doméstica parecem desempenhar um papel importante nos resultados obtidos. Todas as cinco variações nasais estudadas apresentam prevalências elevadas de 38,5% (hipertrofia das conchas médias), 50,5% (curvatura paradoxal das conchas médias), 18% (concha acessória), 94,8% (desvios septais) e 14,2% (esporões septais). Para além disso, o índex de desvio do septo e os esporões septais apresentam uma maior frequência no sexo masculino com relevância estatística. O facto da idade adulta não desempenhar um papel significativo na presença das variações estudadas mostra que o seu desenvolvimento parece acontecer durante o crescimento e é consistente com a hipótese de que a genética pode desempenhar um papel decisivo na sua presença. As formações ósseas nas conchas médias e no interior dos seios maxilares apresentam uma prevalência de 59,3% e 49,8%, respetivamente, ambas mais elevadas no sexo feminino e com diferenças estatísticas significativas. Os dados clínicos e paleopatológicos confirmam que estas alterações ósseas são altamente altamente consistentes com a presença de rinite e rinossinusite maxilar crónica. A alta prevalência destas formações ósseas parece estar associada a várias razões, incluindo o facto da área sinonasal ser a primeira linha de defesa contra numerosas agressões externas, a poluição do ar interior (e.g., devido ao fumo proveniente da queima de combustíveis não processados ao cozinhar em lareiras abertas) e exterior (e.g., industrialização), insalubridade e falta de condições de higiene ou a disfunção mucociliar. Estudos clínicos mostram também que as variações nasais podem estar na origem da doença sinonasal. No presente estudo, a hipertrofia e a curvatura paradoxal da concha média mostram uma associação estatística significativa com a presença de espículas naquela estrutura óssea, enquanto nenhuma das variações estudadas apresenta associação com as formações ósseas nos seios maxilares, o que está em acordo com a maior parte dos estudos clínicos que se debruçam sobre este tema. Embora vários fatores possam ter desempenhado um papel na doença sinonasal no mesmo indivíduo, a sua importância relativa é impossível de estudar em coleções osteológicas. A concha bolhosa e a rinossinusite maxilar evidenciam também uma associação estatisticamente significativa com o desenvolvimento de um padrão de maior largura da face, muito provavelmente porque ambas se desenvolveram durante o período de crescimento dos ossos e estruturas faciais, desempenhando um papel importante no seu desenvolvimento. Foi ainda registada uma miscelânea de alterações osteoblásticas e osteoclásticas nas estruturas ósseas estudadas. Novos casos consistentes com a presença de lepra ou o primeiro caso conhecido de possível ensino da dacriocistorrinostomia moderna são discutidos. O presente estudo sugere uma nova perceção da morfologia e doença sinonasal em populações do passado, mostrando que a sua presença era já frequente em Portugal durante os séculos XIX e XX. Com a utilização de novas metodologias espera-se facilitar futuros trabalhos científicos na área de forma a ser melhor entendida a morfologia e patologia sinonasal e o seu impacto nos seres humanos.

Background: Despite measures to curb unwanted pregnancies and to sustain and expand abortion services, a high number of complications and deaths still occur. The failure of these measures is evidenced by the high number of women who are admitted to the public hospitals of KwaZulu-Natal Province with complications from induced abortions. KwaZulu-Natal Department of Health has repositioned Family Planning to a key priority in its health program in order to improve the situation for women. However, in order to improve the situation, it is necessary to understand the underlying causes. This study sought to identify challenges that affect women's access to Post Abortion Care (PAC) services in KwaZulu-Natal Province, South Africa. It also sought to shed light on the challenges faced by those who render PAC services, as well as assess the skills of those workers as observed while they provided PAC services. After conducting the research on challenges related to access and rendering of post abortion care services, the researcher identified a need to develop guidelines for management of unsafe and induced abortion complications, with the aim to improve the life expectancy of women and prevent maternal deaths. Therefore, an outcome of the study was the development of a PAC management guideline. Purpose: The purpose of the study was two-fold: Phase 1: to explore the challenges faced by women when accessing PAC, and the health care workers who render PAC services, and to assess the PAC skills of the health care workers; Phase 2: to use the findings of Phase 1 to develop guidelines for post abortion care management at selected Hospitals of KwaZulu-Natal Province, South Africa. Methods: The design of the study was guided by the Andersen model of Health Care Utilization. The model focuses on the contextual factors - enabling factors, predisposing factors and need factors - that influence the individual's utilization of health care services. Five districts of KwaZulu-Natal Province, South Africa were selected for the study. A convergent parallel mixed method was used to collect and interpret the data. A qualitative study was used to explore perceptions and challenges of women when accessing PAC; this was carried out by means of in-depth interviews with 23 women who accessed PAC services. Five Focus Group Discussions (FGD) were carried out with 50 health care workers to explore the challenges they experienced when managing abortion complications. A quantitative approach was used for direct skills observation of 92 health care workers. Thematic analysis was used to analyse the qualitative data; descriptive statistics were used to analyse the quantitative data. Results: From the in-depth interview data, several main themes were identified. Women who accessed PAC identified a lack of facilities that offered PAC service, distance from the community to the hospital that provided PAC service, lack of transport, shortage of staff, unskilled staff, shortage of equipment, long waiting queues, stigma and discrimination as challenges associated with delay or avoidance of access to post abortion care services. The main themes raised by the health care providers were lack of support from the management, shortage of staff, lack of training, burnout, unavailability of the guidelines or protocols and shortage of equipment. The quality of PAC services was perceived as poor by both the women seeking care and the health care workers. The main concerns raised by the women were lack of respect, lack of privacy, sharing of bed and insufficient time with the health care provider. The results confirmed that guidelines are needed for the management of post abortion care services. The findings from the qualitative and quantitative parts of the study were used by an expert group to develop PAC management guidelines. The development of the guidelines was in accordance with the WHO models, PICOS & GRADES. The guidelines were validated by the group using a close-ended checklist, analysed with simple descriptive statistics. Conclusion: This study concludes that access to comprehensive quality post abortion care must be provided for all women at times of need. Quality PAC services should be rendered by skilled health care workers in a facility which is accessible and well equipped with functional equipments and updated guidelines. Recommendations: The study therefore recommends that measures should be taken to ensure the provision of quality PAC services. The PAC services should be accessible with the increased number of facilities, adequate trained health care workers with functional equipment and guidelines. Health care workers must receive training and management support to enhance quality PAC services. Privacy and respect must be maintained during provision of PAC services to ensure quality of care and increase demand. There must be continuous community awareness about PAC services which will encourage early-seeking behavior, and reduce fear of stigma and discrimination by the providers of PAC services before the complications arises. This study did not cover all the districts to identify the challenges on delaying PAC service. Therefore, this study recommends additional clinical, operations and community research which will give broader details and understanding on the challenges that cause delay for seeking immediate post abortion care services.
