Paclitaxel (PCX) was the first effective antineoplastic medicine in the treatment of tumors that do not respond to conventional chemotherapy. Clinically, it induces incapacitating arthralgias and myalgias that interfere with the patient quality of life and limit the duration of the treatment. This is observed in up to 57% of the patients using the drug. Despite these clinical manifestations, nothing has been published that could explain the involvement of pro-inflammatory cytokines in the triggering of the hypernociceptive effect of PCX, even though it is known that the drug shares with LPS a signaling pathway started by Toll-like receptors (TLR-2 and TLR-4) that activates genes coding for TNF-α. The literature suggests that there is a crosstalk between these two members of the Toll family and that different agonists of TLR-2 and TLR-4 are able to induce the activation of NF-kB, AP1 and MAP kinase in the generation of TNF-α, a key cytokines in the cascade liberating the final inflammatory mediators that act directly on the nociceptor. Data obtained in laboratory show that the injection of zymozan into rat knee-joints produces a periarthritis characteristic of the hypernociception seen in the knee joint incapacitation test and that PCX (8mg/kg) amplified the response when ¼ of the zymozan (ZY) doses was injected. The amplification was inhibited when animals were pre-treated with inhibitors of cytokines and prostanoids. Objective: To study the role of TNF-α and TLR-4 on the initiation of the potentiating effect of PCX on the experimental arthralgia induced by ZY. Material and Methods: Rats were pre-treated Sc with thalidomide, pentoxifiline, dexametazone, indometacin and celecoxib and then stimulated with an intra-articular subdoses of ZY (250μg/animal). After the first measurement of the paw elevation time in the knee joint incapacitation test, the animals were treated with PCX (8mg/kg ip). On a second trial, rats were treated for three consecutive days with atorvastatin (3, 10, 30mg/kg/day; VO). The following parameters were evaluated: modulation of the effect on the knee joint incapacitation test (JIT), amount of cytokines in the rat’s knee lavage (TNF-α, IL-1 β, IL-6, KC and CINC) and immunohistochemistry for TNF-α, IL-1β and TLR-4 on synovial tissue. Results: It was shown that PCX (8mg/kg) potentiates the experimental arthralgia induced by ZY in the rats as evaluated by the significant increase in paw elevation time (p<0.001) at the 4th h of arthritis in relations to controls. Such effect was significantly inhibited by pre-treatment with thalidomide (45mg/kg) and the inhibition was associated with a decrease in the amount of TNF-α produced by synovial tissue cells and detected in the joint lavage and in the immunohistochemistry for TNF-α. Likewise the inhibition of the amplifying response to PCX was seen with pre-treatment with atorvastatin at the three doses used in the experiment, which was also associated with a lower TNF-α in the joint lavage and perceptible decrease in the immunohistochemistry for TNF-α, IL-1β and TLR-4. Conclusions: PCX potentiates the hypernociception induced by ZY through an indirect effect on synovial membrane resident cells that release TNF-α probably through activation of the NF-kB pathway by TLR-4/MD2, since the potentiating effect was inhibited by atorvastatin, a TLR-4 antagonist. Released TNF-α act starting the cascade of mediators involved in the inflammatory pain and this partially explains the arthralgia in patients treated with PCX.
Paclitaxel (PCX) foi o 1º antineoplásico efetivo no tratamento de cânceres refratários a quimioterapia convencional. Clinicamente, induz artralgias e mialgias de caráter incapacitante que comprometem a qualidade de vida e limitam o tempo de tratamento antitumoral, acometendo até 57% dos doentes. Apesar destas repercussões clínicas nada foi descrito até o momento, visando elucidar o envolvimento de citocinas pró-inflamatórias, na gênese da atividade hipernociceptiva do PCX, já que a droga compartilha com o LPS uma via de sinalização desencadeada por receptores Toll (TLR-4 e TLR-2) para geração de genes que codificam TNF-α. Dados da literatura sugerem que ocorra um “cross-talk” entre esses dois membros da família Toll e, que agonistas diferentes de TLR-2 e TLR-4 são capazes de induzir a ativação de NF-αB, AP1 e MAP kinase e a geração de TNF-α, citocina chave na cascata de liberação de mediadores inflamatórios finais que atuam diretamente no nociceptor. Dados do laboratório registraram que o zymosan (ZY) intrarticular em joelhos de ratos produz uma periartrite característica da hipernocicepção no teste de incapacitação articular (IA), e que PCX (8mg/kg) amplificou essa resposta quando se injetou ¼ da dose do ZY. Tal amplificação foi inibida com o pré-tratamento com inibidores de citocina e de prostanóides. Objetivo. Investigar a participação do TLR-4 e TNF-α na gênese do efeito potencializador do PCX na artralgia experimental induzida por ZY. Material e Métodos. Ratos foram pré-tratados Sc com talidomida (TLD), pentoxifilina, dexametasona, indometacina ou celecoxib e estimulados com subdose de ZY (250μg/animal; i-art). Após a 1ª medida do tempo de suspensão de pata (TSP) no teste de IA, os animais receberam PCX (8mg/kg; ip). Numa segunda etapa os ratos receberam durante três dias consecutivos o pré-tratamento com atorvastatina (3, 10, 30mg/kg/dia; VO). Os seguintes parâmetros foram avaliados: modulação da hipernocicepção no teste de incapacitação articular, dosagem de citocinas em lavado de joelho de ratos (TNF-α, IL-1α, Il-6, KC e CINC) e imunohistoquímica para TNF-α, IL-1α e TLR-4 no tecido sinovial. Resultados. Ficou demonstrado que PCX (8mg/kg) potencializa a artralgia experimental induzida por ZY em ratos avaliada pelo aumento significativo do TSP (p<0,001) na 4ªh de artrite em relação ao controle no teste de IA. Tal efeito foi inibido de maneira significativa pelo pré-tratamento com TLD (45mg/kg) e essa inibição foi associada à redução dos níveis de TNF-α produzido pelas células do tecido sinovial no lavado articular e da marcação imunohistoquímica para TNF-. Da mesma forma a inibição dessa resposta amplificadora do PCX foi ratificado pelo pré-tratamento com atorvastatina nas três doses utilizadas no modelo, também sendo associado à diminuição significativa dos níveis de TNF- no lavado articular e visível redução na marcação imunohistoquímica para TNF-, IL-1 e TLR-4, nas três doses utilizadas. Conclusões. PCX potencializa a hipernocicepção induzida por ZY por um mecanismo indireto sobre células residentes da membrana sinovial que liberam TNF- provavelmente pela ativação da NF-B via TLR-4/MD2, pois esse efeito potencializador foi inibido pela atorvastatina, um provável antagonista de TLR-4. O TNF- liberado age iniciando a cascata de mediadores envolvidos com a dor inflamatória, o que justifica em parte as artralgias dos pacientes em tratamento com PCX.

Full textUma diversidade de alterações osteoarticulares tem sido descrita em pacientes em hemodiálise crônica. O objetivo deste trabalho foi analisar a proporção e o tipo de manifestações músculo-esqueléticas (MME) nos pacientes em programa de hemodiálise, em três centros da região metropolitana do Recife, e relacioná-las com as variáveis: sexo, etnia, idade atual do paciente e ao iniciar a diálise, e tempo de tratamento dialítico. Inicialmente, foram aplicados questionários em 197 pacientes distribuídos nos três centros no período de março de 2001 a janeiro de 2002. Após excluir 35 pacientes com diagnóstico prévio de doença reumatológica, investigou-se a presença de sinais e/ou sintomas de MME em 162 pacientes. A média de idade foi de 47,3 anos, a média da idade no início do tratamento foi de 43,8 anos, 94 pacientes (58%) eram do sexo masculino e 120 (74,1%), não caucasóides. O tempo médio do tratamento dialítico foi de 44,1 meses, e foi utilizada a membrana de polissulfona em todos. Resultados: MME foram observadas em 55 (34%) dos 162 pacientes do estudo. Destes, 38 apresentaram um único tipo de manifestação e 17 pacientes, mais de um tipo (16 apresentaram dois e, um, três tipos), perfazendo um total de 73 manifestações distribuídas entre articulações (44), ossos (18), estruturas neuro-musculares (seis) e periarticulares (cinco). A artralgia foi responsável por 46,6% de todas as MME e o joelho foi a articulação mais acometida por ela (52,9% dos casos). A dor óssea foi a segunda queixa mais comum (21,9%), as alterações periarticulares corresponderam a 6,8% das MME, e síndrome do túnel do carpo, deformidades ósseas e tumorações articulares ocorreram em 4,1%, 2,7% e 2,7% do total de MME, respectivamente. Entre os 55 pacientes, alterações articulares foram encontradas em 72,7% deles, ósseas em 32,7%, neuro-musculares em 10,8% e periarticulares 9,1% dos pacientes. Neste estudo, foi observado relação entre o tempo médio de tratamento dialítico (59.8 meses) e o desenvolvimento de MME (p<0.001). A partir destes dados, conclui-se que a proporção de MME nos nossos pacientes foi de 34%; as manifestações articulares foram as mais observadas e a artralgia foi a queixa mais comum. No nosso estudo, com exceção do tempo de tratamento dialítico, as demais variáveis não mostraram associação com o aparecimento de MME

Full textThis aim of this study was to evaluate the efficacy of piroxicam associated with low-level laser therapy (LLLT) in the treatment of arthralgia of the temporomandibular joint (TMJ). Thirty-two patients (mean age 32,44 years old ± 13,02) with TMJ arthralgia were enrolled in the study and divided into 3 groups: LLLT+ piroxicam (LPi), LLLT+placebo piroxicam (L) e piroxicam+placebo LLLT (Pi). Patients were managed for ten days. Follow-up evaluations were done at the 1st, 3rd, 8th and 10th days of treatment and 30 days after the end. The presence and intensity of spontaneous pain, pain on palpation and mandibular maximum vertical opening were measured. Data were analyzed using Friedman and Wilcoxon tests or ANOVA and t test, considering a significance level of 5%. Improvements were found for factors spontaneous pain and pain on palpation in the intragroup analysis, although no significant differences were detected among groups. However, evaluation of 30 days after the treatment showed significant differences among groups, that the group Pi had the lowest pain on palpation (p=0,01) and the lowest pain for temporal muscle (p=0,02). The obtained results suggest that the association of LLLT and piroxicam were not more effective than single therapies in the treatment of TMJ arthralgia, and all treatments were effective in decreasing pain. The use of piroxicam alone was more effective in the following 30 days for pain on palpation over the use of LBP alone.

Full textTemporomandibular Joint (TMJ) internal derangements are characterized by anterior disk displacement (ADD) and/or as arthralgias. An important clinical presentation in these cases is the painful tenderness to manual palpation or decreased Pressure Pain Threshold (PPT), determined with an algometer. The present study aims to determine, based on high specificity levels, the more appropriate PPT value to discriminate healthy TMJs from those with painful inflammatory processes as well as to determine the influence of asymptomatic disk displacement with reduction (DDWR) in this scenario. A sample of 60 individuals from both genders with age between 18 and 50 years were evaluated by Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and divided into three groups: 20 patients with clinical diagnosis of TMJ arthralgia, 20 patients with clinical diagnosis of asymptomatic DDWR and 20 individuals with no TMJ pain or noise (control group). All individuals were submitted to an exam of magnetic resonance imaging for the analysis of disk position to confirm the physical exam (RDC/TMD) and to validate the group distribution. An algometry exam was performed on the TMJ lateral pole and the individuals of the arthralgia group also filled out a Visual Analogue Scale (VAS). The data were analyzed by variance test (ANOVA) and by Pearson correlation test with 5% of significance. Levels of specificity and sensibility, and ROC curves were also determined. The arthralgia group presented significant lower PPT (mean of 1.07 kgf/cm2 ± 0.445) values than the others. DDWR group (mean of 1.90 kgf/cm2 ± 0.647) has shown significant lower PPT values when compared to the control group (mean of 2.46 kgf/cm2 ± 0.593). A significant correlation between the PPT and the VAS and the time of pain experience was not found. 100% of specificity and 90% of sensitivity were obtained when 1.56 kgf/cm2 was applied to the TMJ (ROC=0.99). This value was considered to be the most appropriate to detected TMJ arthralgia.

Full textThe aim of this research was to test the hypothesis that the treatment with intraoral appliances (occlusal splints and device NTI) is beneficial to the control of symptoms and signs of arthralgy of temporomandibular joint (TMJ) when compared to a control group. Therefore, sixty patients were analyzed by questionnaires and tests that determined the presence of arthralgy of the TMJ and its intensity. Then this sample was randomly divided into three groups of 20 patients each: the first group was treated with repositioning occlusal splint and orientations; the second group received an anterior device (NTI nociceptive trigeminal inhibitory system), the third group of patients (the control group) just received counseling and orientations for behavioral changes. The devices were installed and used in partial time (only during sleep), and the follow-ups were performed after 2, 6 weeks and 3 months. In these sessions, patients were evaluated according the visual scale of pain (VAS), presence of noise, active mouth opening, temporomandibular joint algometry and comfort in the use of intraoral appliances for the experimental groups. The results were analyzed with Kruskal-Wallis, ANOVA and Tukey, adopting a significance level of 5%. All three groups showed improvement in signs and symptoms of temporomandibular joint arthralgy, suggesting that occlusal appliances and behavioural orientations may be beneficial in the treatment of this condition. However, the management with occlusal appliance and orientations seems to have an earlier effect. The use of occlusal repositioning splint is more comfortable at the beginning of the treatment of patients contributing to a faster reduction of their pain. Long - term studies with the NTI device are needed to establish its effectiveness and absence of adverse dental effects.

Full textPresently it has been observed that the most common physical affection in the locomotor system in medical and sportive clinic, among active young adults and adolescents are related to the knee, being femoropatellar pain symptom the most frequent. Although, this condition is unknown for those who are specialists in knee when they try to identify a specific cause and an agreement. As a way of trying to contribute for the elucidation of this problem, it has been decided to execute this investigative study trying to find clinic, radiographic and isokinetic differences among female individuals, with and without the above mentioned symptom, between 15 and 20 years old. 23 young females with bilateral femoropatellar pain were analyzed, with unknown affection, and 20 without symptoms (46 symptomatic knees and 40 asymptomatic). All of them were submitted to radiographic exams (anteroposterior, profile and axial incidences), were it was verified the femorotibial alignment, the patellar height, the groove angle, the congruence angle and the femoropatellar lateral angle. It was also measured the hamstring shortness and Q angle in clinic exam and, the individuals of this study were submitted to strength evaluation, by isokinetic dynamometry of the extensor and flexor muscles of knees and hips, besides hip medial and lateral rotators and the adducts and abducts. After analyzing the results, it can be observed that the statistically significant differences among studied groups were related to the inferior member alignment, with the Q angle presenting p value < 0,001, the femoropatellar lateral angle p value = 0,006, the groove angle p value < 0,001, the congruence angle p value = 0,027 and, the only one statistically different parameter in isokinetic dynamometry was the torque peak angle of hip extension with p value = 0,03. According to the results of comparison between symptomatic and asymptomatic groups there is an important relationship between bad alignment of the knee joint with the studied symptomatology, but it cannot be appointed one or another as the most important for the appearing of the pain, or maybe it still can be said that these disarrangements can predispose the knee to the symptom, but maybe they are not the primary causes of the affection. It was shown that the raise of the Q angle and the hamstring shortness are not the causes of femoropatellar pain. It was verified that individuals with or without the symptom do not show difference in relation to the muscular strength of the involved muscles in movement of the hip and knee. The femoropatellar lateral angle presented higher average in the asymptomatic group, while the average of the groove angle, in the same group, was smaller. Yet the congruence angle presented a positive average in the asymptomatic group and a negative average in the group with pain, showing that the patella in the group with pain has its apex more medially than the control group

Full textThe aim of this study was assess the influence of Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis II parameters on treatment outcome of low-level laser therapy (LLLT) associated with piroxicam in patients with TMD. Thirty-two patients (mean age 33.2 years old ± 13.4) with temporomandibular joint (TMJ) arthralgia were enrolled in the study and received three kinds of treatment: LLLT + piroxicam (LPi), LLLT + placebo piroxicam (L) e piroxicam + placebo LLLT (Pi). Patients were managed for ten days. Follow-up evaluations were done at the 1st and 4th consults. The presence and intensity of spontaneous pain through the visual analogue scale (VAS), painful palpation and mandibular maximum vertical opening were measured. The therapeutic outcomes of this population were compared between the classifications of axis II scores: graded chronic pain (GCP), depression and non-specific physical symptoms (NEPS). The data was analyzed using the following statistic models: Fisher\'s test, Student t test, Wilcoxon, Mann-Whitney U test, Kruskal-Wallis test and Analysis of Variance. The statistical significance level set was p<0.05. The variables VAS, painful joint and muscle palpation showed improvement over time. Significant difference was found between GCP groups and maximum mouth opening on the 4th session and painful TMJ palpation; between NEFS (including and excluding pain items) and painful muscle palpation on the 1st consult. Between groups of GCP and VAS\'s variables it was found a marginally significant relation, showing p-values near 0.05 (p<0.1). No statistical difference was found on the comparison between depression and the physical variables considered. Thus, it is possible to conclude that there is an association between high incapacity and higher mean values to painful joint palpation, severe NEPS including and excluding pain items and baseline painful muscle palpation. No relation between depression and the studied variables was observed.

Full textIntroduction: Hallux valgus, is an important cause of feet pain and discomfort and affects 28% of adults and 37% of elderly, predominantly in female population. To achieve the deformity heal, surgical treatment is needed, which main goal is to treat incapacity related to pain (IRP). However, one year after hallux valgus surgical treatment, moderate to severe chronic pain persists in 21% during rest and 43% during walking. This abnormal response is part of the symptoms that constitute central sensitization syndrome (CSS), which is due to a maladaptive neuroplasticity process. Sensitized patients, not only are more likely to develop postoperative persistent pain, but also experience more intense postoperative pain comparing to non-sensitized patients, due to the amplification of nociceptive inputs and inhibitory systems disfunction. Related to neuroplasticy process, proteins such as brain neurotrophic factor (BDNF) are found. This neurotrophin participates in the LTP process, a mechanism of neuroplasticity that sustains the process of pain memory. The increase of BDNF increases the LTP, while the reduction of its levels attenuates this phenomenon. Therefore, the relationship of BDNF levels with disease severity may confirm the systemic influence of this biomarker on sustained pain states. In order to alter long-term pain-induced maladaptive neuroplasticity, transcranial direct current stimulation (tDCS), a non-invasive technique, which aims for the central nervous system modulation for pain control, may become a therapeutic option for postoperative pain. However, the effect of tDCS applied in the preoperative period has not been explored yet with the intent of improving the postoperative pain control in sensitized patients, neither in postoperative rehabilitation. In this study, it was chosen to use tDCS due to its potential to counter-regulate the maladaptive neuroplastic alterations associated to chronic pain. Objective: to evaluate the effect of preoperative tDCS compared to tDCS-sham in the pain control and in the rehabilitation of patients with arthralgia of the first metatarsalfalangeal articulation submitted to hallux valgus surgical correction. Method: it is a randomized, double-blinded, placebo-sham controlled clinical trial, which includes 40 female patients, between 18 and 70 years old, candidates to hallux valgus surgical treatment by combined Chevron + Akin osteotomy due to arthralgia of the first metatarsalfalangeal articulation. The patients were randomized and divided into two groups that were treated with two tDCS or tDCS-sham sessions of 20 minutes each in preoperative period. The stimulation was done by 2mA continuous current through the anodal electrode on the primary motor cortex (M1) and the catodal on the contralateral supraorbital area. The outcomes were: VAS(0-10) scores, analgesic consumption, DRP assessed by the B-PCP: S, the function of the descending pain modulator system, assessed by the CPM test and the serum and CSF levels of BDNF. Results: a-tDCS group showed lower scores on Visual Analogue Scale [VAS(0-10)] at rest and during walking (P<0.001). At rest, the difference between both groups was 2.13cm (95%CI=1.59 to 2.68) while during walking was 1.67cm (95%CI=1.05 to 2.28). The a-tDCS group, when compared to s-tDCS, showed reduced need of daily analgesic intake from 1.37 (0.63) to 1.81 (0.64) mean doses, respectively (P<0.001). Active tDCS improved the DRP, as demonstrated by a greater reduction in the Brazilian Profile of Chronic Pain: Screen (B-PCP:S) (mean difference of 9.41 points, 95%CI=0.63 to 18.21) and also increased the function of descending pain modulatory system (DPMS) during conditioned pain modulation (CPM-task), with a medium size effect. The increased function of this system represents the reversal of maladaptive neuroplastic changes promoted by chronic pain. Conclusion: Two preoperative anodic tDCS sessions applied over M1 improved postoperative pain, as demonstrated by reduction in the pain scores, analgesic consumption and DRP. In addition, these results suggest that the effects of preoperative tDCS on these outcomes involved improving the function of pain modulation systems and neuroplasticity mechanisms as measured by BDNF.

Full textThe mandibular movements used in speech modify the spaces to make possible the different articulatory postures proper to each sound. The temporomandibular dysfunctions can arise general modifications in the mandibular movements due to the modification in the muscular and articular conditions. The electrognathography, a computerized exam used to complement the diagnosis of those dysfunctions, allows to delineate and record in an objective way the mandibular movements, determining their range and speed. Thus, the goal of this study was to check the characterization of mandibular movements in speech for Brazilian Portuguese, in individuals with temporomandibular dysfunctions and in asymptomatic individuals, through computerized electrognathography, analyzing possible interferences of those dysfunctions as for the following issues: mandibular opening and closing speed; vertical, anteroposterior and lateral range of those movements. For such, 135 adult subjects were divided in two groups: GI with 90 participants with temporomandibular dysfunctions and GII with 45 asymptomatic participants. Those movements were also checked based on pain degrees, using numeric scale, namely: zero for pain absence, 1 for light pain, 2 for moderate pain and 3 for severe pain. Mandibular movements were observed in the sequential nomination of balanced figures as for the occurrence of tong phonemes. The records were obtained with computerized electrognathography (BioEGN - BioPak system) through the reception of signals from a magneto without interfering in the occlusion and movement extension. The analysis of such results showed statistically significant differences between the averages of the values obtained for the two groups as for the opening and retrusion range, and between the averages of speed both for mandibular opening as well as for mandibular closing in speech. Statistically significant differences were not found among the results obtained for the two groups as for the presence and range of the deviations in laterality during the speech. Prevalence of bilateral deviations was verified for GII and of unilateral deviations for GI with statistically significant differences. As for the different pain degrees, the differences indicated as significant for opening range and mandibular closing speed were verified to occur between zero degree and all other pain degrees. For mandibular opening speed in speech, statistically significant differences were obtained between zero degree and three degree. Mandibular movements in speech were verified to be discreet, with anteroposterior component and deviations in laterality. The presence of temporomandibular dysfunctions arises reduction of the maximum mandibular opening and retrusion ranges, prevalence of unilateral deviations and also speed reduction both concerning opening as well as closing of mandibular movements during speech. The different pain degrees do not seem to determine larger reduction of maximum range and speed as for such movements. This study made possible to describe the three dimensional thresholds of mandibular movements in speech for Brazilian Portuguese, as well as the averages concerning the maximum values of opening and closing speed during those movements, for the two groups of investigated individuals

O v?rus da Chikungunya (CHIK) ? uma epidemia no Brasil com 170.000 casos no primeiro semestre de 2016. Mais de 60% dos pacientes apresentam rea??o e remiss?o de artralgia cr?nica com dor debilitante que dura anos. N?o existem agentes terap?uticos espec?ficos para tratar e reabilitar pessoas infectadas com CHIK. Dor persistente pode levar ? incapacita??o exigindo tratamento farmacol?gico de longo prazo. Os avan?os nos tratamentos n?o farmacol?gicos s?o necess?rios para promover o al?vio da dor sem efeitos colaterais e restaurar a funcionalidade. Aqui, n?s demonstramos que a Estimula??o Transcraniana com Corrente Cont?nua (ETCC) sobre o c?rtex motor prim?rio reduz significativamente a dor na fase cr?nica da CHIK. Nossos achados sugerem que a ETCC pode ser uma terapia eficaz, barata e implant?vel em ?reas que n?o possuem recursos e que apresentam um grande n?mero de pacientes com dor cr?nica persistente gerada pela CHIK.
The Chikungunya (CHIK) virus is epidemic in Brazil, with 170,000 cases in the first half of 2016. More than 60% of patients present relapsing and remitting chronic arthralgia with debilitating pain lasting years. There are no specific therapeutic agents to treat and rehabilitee infected persons with CHIK. Persistent pain can lead to incapacitation, requiring long-term pharmacological treatment. Advances in non-pharmacological treatments are necessary to promote pain relief without side effects and to restore functionality. Here, we demonstrate that the transcranial direct current stimulation (tDCS) across the primary motor cortex significantly reduces pain in the chronic phase of CHIK. Our findings suggest tDCS could be an effective, inexpensive and deployable therapy to areas lacking resources with a great number of patients with chronic CHIK persistent pain.

Full textIntroduction: Leprosy is a chronic infectious disease caused by Mycobacterium leprae. It is considered one of major public health issue in developing countries. The important clinical signs of leprosy are hypopigmented or reddish localized skin lesions with loss of sensation and peripheral nerves involvement. Musculoskeletal manifestations were described in leprosy adult patients and these involvements were rarely described in pediatric leprosy population. Objective: To evaluate musculoskeletal involvement and autoantibodies in pediatric leprosy patients. Methods: 50 leprosy patients and 47 healthy children and adolescents were assessed according to musculoskeletal manifestations (arthralgia, arthritis and myalgia), musculoskeletal pain syndromes (juvenile fibromyalgia, benign joint hypermobility syndrome, myofascial syndrome and tendinitis) and a panel of autoantibodies and cryoglobulins. Health assessment scores and treatment were performed in leprosy patients. Results: The frequency of at least one musculoskeletal manifestation was significantly higher in leprosy patients compared to controls (14% vs. 0%, p=0.0012) and five leprosy patients had asymmetric polyarthritis of small hands joints (10% vs. 0%, p=0.057), Nerve function impairment, type I leprosy reaction and silent neuropathy were significantly observed in leprosy patients (p=0.0006; p=0.003; p=0.0059; respectively). None of the patients and controls presented musculoskeletal pain syndromes and the frequencies of all antibodies and cyoglobulins were similar in both groups (p>0.05). Further analysis of leprosy patients showed that the frequencies of nerve function impairment, type I leprosy reaction and silent neuropathy were significantly observed in patients with versus without musculoskeletal manifestations (p=0.0036; p=0.0001; p=0.309; respectively), as well as multibacillary subtypes in leprosy (86% vs. 42%, p=0.045). The median of physician visual analogue scale (VAS), patients VAS, pain VAS and CHAQ were significantly higher in leprosy patients with musculoskeletal manifestations (p=0.0001; p=0.002; p=0002; p=0.001; respectively). Conclusions: This was the first study to identify musculoskeletal manifestations associated with nerve dysfunction in pediatric leprosy patients. Hansen´s disease should be included in the differential diagnosis of asymmetric arthritis, especially in endemic regions

Full textOBJECTIVES: Evaluate the antinociceptive and chondroprotective effects of glucosamine sulfate and chondroitin sulfate. METHODS: Male Wistar rats underwent anterior cruciate ligament transection (ACLT) or sham operation of the right knee. Animals were treated p.o. with glucosamine sulfate (Glu) 500 mg/kg, the combination of glucosamine sulfate 500 mg/kg and chondroitin sulfate 400 mg/kg (GluChon), or saline, since 7 days prior to surgery until the sacrifice 70 days after ACLT. A positive control group received meloxicam 6 mg/kg s.c. for antinociceptive evaluation comparisons. Joint pain was evaluated with rat incapacitation test. Animals were sacrificed 7,14,28 or 70 days after ACLT. The severity of histopathologic lesions was evaluated on femoral condyles after hematoxylin-eosin or toluidine blue staining with OARSI grading and staging system. Cartilage extracted glycosaminoglycans (GAGs) concentration was assessed after agarose gel electrophoresis. GAGs\' molecular weight was evaluated after polyacrylamide gel electrophoresis. NO release in synovial fluids was assessed 7 days after ACLT. RESULTS: GluChon reduced joint pain (p<0.01). Glu also reduced joint pain, but results did not reach statistical significance. A significant increase in articular cartilage\'s GAGs concentration was observed in OA animals (77.68±3.38 µg/mg) as compared to sham (53.46±4.58 µg/mg). OA animals also had significantly higher molecular weight GAGs than sham (p<0.01). GluChon prevented both GAG concentration and molecular weight elevations in OA animals, and that was associated with significant less cartilage damage assessed by histopathologic examination (p<0.05). Glu effects were less evident, and did not reach statistical significance. Glu was associated with significant higher concentrations of NO in synovial fluid. CONCLUSIONS: GluChon was antinociceptive on the ACLT model in rats. Articular cartilage damage was associated with increased amounts of GAG with higher molecular weight, and the prevention of these alterations with GluChon treatment was associated with less histopathologic damage. GluChon was more efficient than Glu for both pain and articular cartilage damage reduction, suggesting that combined treatment is better than glucosamine sulfate alone.

Full textINTRODUCTION: C virus infection is a major public health problem and has become the leading indication for liver transplantation. With a worldwide distribution, is the second most common chronic viral worldwide. However, chronic hepatitis C is more than a liver disease. Patients with chronic HCV infection may develop a large number of extra hepatic manifestations regardless of the severity of liver disease. There are many rheumatic diseases associated with HCV infection including arthralgia, myalgia and arthritis. METHODS: A cross-sectional study carried out among patients treated in outpatient Hepatitis Clinical Division of Infectious and Parasitic Diseases of the HC-USP, in São Paulo, in the period from 2004 to 2008, selected 243 patients who met the inclusion criteria and signed the consent form after clarification of the research. An interview was conducted with patients which were collected demographic, epidemiological and clinical-laboratory. Laboratory tests were carried, biochemical, hematological, immunological, quantitative PCR HCV RNA and HCV genotyping. The evaluation of the characteristics of HCV infection (epidemiological, histological, virological) associated with extrahepatic manifestations rheumatology clinics (those with prevalence > 10%) and laboratory (with prevalence > 5%) were performed using univariate and multivariate analysis (regression logistics). Odds ratios (OR) and adjusted confidence intervals of 95% (95% CI) were derived from the ratio of the final multivariate logistic model. All analyzes were performed with the SPSS statistical package. RESULTS: Of the 243 patients studied were able to determine the likely form of infection in 147 (60.49%). Of the 147 patients, 93 (38.27%) had previous blood transfusion, 10 (4.11%) had a history of injection drug use for more than 1 years, 15 (6.17%) had prior use of the drug is inhaled over 1 year, 11 (4.52%) were health professionals with a history of accidents with sharp objects, 10 (4.11%) underwent tattooing and 8 (3.29%) had a partner with hepatitis C chronic. In this analysis, 148 (60.9%) of patients with chronic hepatitis C complained of arthralgia, 145 (59.7%) complained of myalgia, 144 (59.3%) of fatigue. Arthritis was present in 50 (20.57%) of the patients evaluated in this study. Among patients with arthritis of this study, involvement was predominantly polyarticular in 36 (72%) of them, affecting large and small joints simultaneously in 29 (58%). Age greater than 50 years, back pain and crepitus in the joints proved to be factors associated with arthritis. We observed that female smoking important and advanced liver fibrosis (F3 and F4) were associated with arthralgia. Female gender and smoking were important factors associated with myalgia. CONCLUSION: We found a high prevalence of musculoskeletal manifestations among patients with chronic hepatitis C of this service. The most common risk factors for the presence of extra hepatic manifestations were female and older than 50 years. The autoantibodies, although frequently not statistically significant compared with the major musculoskeletal manifestations analyzed. Inflammatory infiltrate and liver transaminase levels did not show statistical significance

Full textINTRODUCTION: Temporomandibular Disorder (TMD) is an important public health problem, affecting 10 to 25% of the population. It has a major impact on quality of life and high social and economic costs. Manual Therapy (TM) has been a proposed approach but with effectiveness yet to be demonstrated. OBJECTIVE: To verify the added benefit of including TM in the base intervention protocol of patients with TMD due to Arthralgia. METHODOLOGY: It was used an 'N-of-1 trial', where 4 paired treatment cycles were administered to 8 patients, each cycle consisting of the exclusive application of occlusal splint (GO), phase A, or the GO + TM protocol, phase B. Each cycle lasted 2 weeks, one for each phase. The order of treatments was randomly assigned: sequence 1 (AB BA BA AB) and sequence 2 (BA AB AB BA). Maximum mouth opening (AMB) was measured in mm, pain intensity by Numerical Pain Scale (END), functional limitation by Jaw Functional Limitation Scale 20 (JFLS-20) and perception of change by the Patient Global Impression of Change (PGIC). RESULTS: Of the 7 participants who completed the 4 treatment cycles, we did not find a trend or pattern in the effect obtained with the introduction or withdrawal of TM on AMB, END, JFLS-20, or PGIC. The average mouth opening was slightly higher in the TM introduction phases (37.79 ± 4,086 mm) compared to the GO-only phases (37.32 ± 4,423 mm), but the observed differences (0.464) are not statistically significant (IC95%: - 0.350-1.278, p=0.252). The pain intensity reduction was slightly higher in the TM introduction phases (2.89 ± 2.2) compared to the GO-only phases (2.82 ± 2.28), but the observed differences (0.071) are not statistically significant (IC95%: -0.308-0.451, p=0.702). Regarding the reduction of functional limitation, the mean reduction was slightly higher in the TM introduction phases (26.96 ± 30.51) compared to the GO-only phases (28.96 ± 32.77), but the observed differences (-2.0) are not statistically significant. (IC95%: -6.19- 2.19, p=0.336). CONCLUSION: The results show that there are no statistically significant differences in either outcome between treatment A and B, so the study hypothesis is not confirmed.

Full textIntroduction: With the increasing incidence of cancer in the world’s population, a greater understanding of side effects caused by chemotherapy treatments is urgently needed such as in Rheumatology, an area not much explored in the literature. Different musculoskeletal manifestations with various chemotherapy drugs have been reported for distinct types of cancer. Symptoms can occur even with negativity of radiologic or laboratory findings indicative of rheumatologic diseases. There are some specific syndromes described. To date, there is no comprehensive explanation of these phenomena, although some hypotheses have been considered. In this context, a survey of follow-up cases was performed in Rheumatology consultation and a comparison with the existing literature has been establish. Materials and methods: This is an observational, descriptive and clinical research study (case report). Patients with a history of cancer and associated chemotherapy were included if in current follow-up appointments and had no rheumatologic complaints prior to chemotherapy. Those with rheumatologic symptoms before cancer, as well as with complaints from bone metastasis or paraneoplastic syndromes were excluded. The characterization of the sample was based on the following parameters: age, sex, type of cancer, time to onset of rheumatologic symptoms, clinical presentation, laboratory results, rheumatologic treatment and evolution of complaints. Results: We identified 6 clinical cases of female patients, all with a history of breast cancer. All were in oncologic treatment with aromatase inhibitors. In 5 patients symptoms appeared soon after the beginning of therapy (between 1 and 6 months); the remain presented complaints in a period of months to years. In none, there was a registry of rheumatological pathology prior to chemotherapy. The most common manifestation was arthralgias with morning stiffness ranging from 5 minutes to 1 hour and night pain. The most affected joints were the small ones of the hands. In 5, positive antinuclear antibodies were detected; 1 also had positivity to anti-Ro antibodies, lupic antibody and rheumatoid factor. None had positive anti-cyclic citrullinated peptide antibody. Most patient's complaints were relieved by associations between non-steroidal anti-inflammatory drugs and/or disease modifying antirheumatic drugs and/or glucocorticoids. To date, none had spontaneous remission of symptoms. Conclusion: Rheumatologic pathology after chemotherapy may have several forms of presentation, from non-specific arthralgia, rheumatoid arthritis, to specific syndromes. It may or may not be accompanied by positive laboratory findings, with a variable temporal presentation and whose symptomatic control can be effectively and rapidly achieved with oral medication.
