CO 2 laser, radiofrequency, and promestriene in the treatment of genitourinary syndrome of menopause in breast cancer survivors: a histomorphometric evaluation of the vulvar vestibule.

OBJECTIVE: This study aimed to compare the efficacy of CO 2 laser, radiofrequency, and promestriene in treating genitourinary syndrome of menopause in women with breast cancer receiving adjuvant therapy and to analyze the clinical and histological findings of the vulvar vestibule. METHODS: Women with moderate-to-severe symptoms of vulvar atrophy were enrolled. The participants were evaluated according to pretreatment and posttreatment protocols using the visual analog scale and clinical assessments, which included a gynecological examination and vestibular biopsy. Participants were randomly assigned into the laser, radiofrequency, or promestriene groups. Participants in the energy treatment groups underwent three consecutive monthly outpatient vulvovaginal treatment sessions, whereas those in the control group were administered promestriene for 4 months. During a follow-up visit 30 days posttreatment, the participant global posttreatment impression of improvement was evaluated using a Likert scale. RESULTS: Seventy women completed treatment. Histological vulvar atrophy was identified in four (5.7%) of the pretreatment vulvar samples. Postintervention, all histological parameters were normalized. Significant improvements in symptoms were observed, as all three groups showed a reduction in the visual analog scale score, with no statistically significant differences among them. A high level of satisfaction was reported posttreatment in all groups. No damage to the histological structure of the vulvar vestibule or relevant clinical adverse events were identified posttreatment. CONCLUSIONS: Laser, radiofrequency, and promestriene delivered comparable, significant symptom improvements among women with breast cancer receiving adjuvant therapy. These treatments did not cause structural tissue damage or other clinical complications.

An Intraindividual Comparison of Open versus Paine Retinaculotome Release for Bilateral Carpal Tunnel Syndrome.

The main purpose of this research was to do an intraindividual comparison of outcomes between the open ulnar incision (OUI) and the Paine retinaculotome with palmar incision (PRWPI) techniques in patients with bilateral carpal tunnel syndrome (CTS). The patients underwent OUI surgery on one hand and PRWPI surgery on the contralateral hand. The patients were evaluated with the Boston carpal tunnel questionnaire, visual analogue scale for pain, palmar grip strength, and fingertip, key, and tripod pinch strengths. Both hands were examined in the preoperative and postoperative periods after 2 weeks, 1 month, and 3 and 6 months. Eighteen patients (36 hands) were evaluated. The symptoms severity scale (SSS) scores were higher, in the preoperative period, in the hands that underwent surgery with PRWPI ( p -value = 0,023), but lower in the 3rd month postoperative ( p -value = 0.030). The functional status scale (FSS) scores were lower in the periods of 2 weeks, 3 months, and 6 months ( p -value = 0,016) on the hands that underwent surgery with PRWPI. In a different two-group module study, the PRWPI group presents the SSS scores average on the 2nd week and 1st month, and the FSS scores average on the 2nd week, less 0.8 and 1.2 points respectively comported to open group. The hands that underwent surgery with PRWPI presented significantly lower SSS scores at 3 months postoperative, and lower FSS scores at 2 weeks, and 3 and 6 months postoperative, compared to open surgery group.

Resumo O principal objetivo desta pesquisa foi fazer uma comparação intraindividual dos resultados entre as técnicas de incisão ulnar aberta e retinaculótomo de Paine com incisão palmar em pacientes com síndrome do túnel do carpo (STC) bilateral. Os pacientes foram submetidos à cirurgia aberta em uma mão e cirurgia com retinaculótomo de Paine na mão contralateral. Os pacientes foram avaliados com o Boston carpal tunnel questionnaire, escala visual analógica para dor e força de preensão palmar, pinça lateral, pinça polpa-polpa e trípode. As duas mãos foram examinadas antes da cirurgia e 2 semanas, 1 mês, 3 e 6 meses após a cirurgia. Dezoito pacientes (36 mãos) foram avaliados. As pontuações da escala de gravidade dos sintomas (EGS) foram maiores no pré-operatório nas mãos submetidas à cirurgia com retinaculótomo de Paine (p = 0,023), mas menores no 3° mês após o procedimento (p = 0,030). As pontuações da escala de estado funcional (EEF) foram menores às 2 semanas, 3 meses e 6 meses (p = 0,016) nas mãos submetidas à cirurgia com retinaculótomo de Paine. Em um estudo de módulo de diferença de dois grupos, o grupo submetido à cirurgia com retinaculótomo de Paine apresentou pontuações médias de EGS na 2ª semana e 1° mês e de EEF na segunda semana inferiores a 0,8 e 1,2 pontos, respectivamente, em comparação ao grupo submetido ao procedimento aberto. As mãos submetidas à cirurgia com retinaculótomo de Paine apresentaram escores significativamente menores de EGS em 3 meses e de EEF em 2 semanas, e aos 3 e 6 meses após a cirurgia em comparação a técnica aberta.

Use of aerobic treadmill exercises on nerve regeneration after sciatic nerve injury in spontaneously hypertensive rats.

PURPOSE: Various postoperative protocols have been proposed to improve outcomes and accelerate nerve regeneration. Recently, the use of physical exercise in a post-surgical neurorraphy procedure has shown good results when started early. We experimentally investigated the hypothesis that post-operative exercise speeds up results and improves clinical and morphologic parameters. METHODS: Isogenic rats were randomly divided into four groups: 1 SHAM; 2 SHAM submitted to the exercise protocol (EP); 3 Grafting of the sciatic nerve; and 4 Grafting of the sciatic nerve associated with the EP. The EP was based on aerobic activities with a treadmill, with a progressive increase in time and intensity during 6 weeks. The results were evaluated by the sciatic functional index (SFI), morphometric and morphologic analysis of nerve distal to the lesion, and the number of spinal cord motor neurons, positive to the marker Fluoro-Gold (FG), captured retrogradely through neurorraphy. RESULTS: Functional analysis (SFI) did not show a statistical difference between the group grafted with (-50.94) and without exercise (-65.79) after 90 days. The motoneurons count (Spinal cord histology) also showed no diference between these groups (834.5 × 833 respectively). Although functionally there is no difference between these groups, morphometric study showed a greater density (53.62) and larger fibers (7.762) in GRAFT group. When comparing both operated groups with both SHAM groups, all values were much lower. CONCLUSIONS: The experimental model that this aerobic treadmill exercises protocol did not modify nerve regeneration after sciatic nerve injury and repair with nerve graft.

Disability of Arm, Shoulder and Hand and Michigan Hand Outcomes Questionnaires: Exploring Responsiveness and Diagnostic Performance in a Sample of Outpatients with and without Hand and Wrist Complaints.

Objective The present study aimed to verify whether, in an adult population with nontraumatic complaints in the upper limbs, (1) the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and the Michigan Hand Outcomes Questionnaire (MHQ) are susceptible to a "ceiling effect" when compared with a sample of healthy subjects; and (2) to determine cutoff points for diagnostic performance and the intercorrelation for DASH and MHQ in both samples. Methods This was a prospective, comparative, nonrandomized study. In total, 150 subjects were included, with 75 in the case group (with disease) and 75 in the control group (without disease). This was a sample of patients recently admitted to a hand surgery outpatient clinic. Controls were matched to clinical cases according to inclusion. The ceiling effect was determined by a maximum response rate (> 15%); receiver operating characteristic (ROC) curves determined cutoff points for sickness definition, and DASH and MHQ sensitivity and specificity. Statistical significance was set at p < 0.05. Results The DASH and MHQ questionnaires had no ceiling effect for the case group. In this group, 18 (24%) patients had the maximum DASH score, but none (0%) had the maximum MHQ score. For the control group, 1 (1.33%) subject had the maximum DASH score, but none scored for MHQ. For case determination, DASH scores of 7.1 had 80% sensitivity and 60.3% specificity, whereas MHQ scores of 76.9 had 56.2% sensitivity and 97.3% specificity. Conclusion The DASH and MHQ questionnaires are reliable tools to measure the impact of hand and wrist morbidities on daily activities, and they are not susceptible to ceiling effects. The DASH questionnaire is more sensitive for patient identification, whereas the MHQ is more specific. As such, the MHQ seems more appropriate when a more specific functional increase is expected.

Resumo Objetivo Verificar se, em uma população adulta com queixa não traumática dos membros superiores, (1) os questionários Disability of the Arm, Shoulder and Hand (DASH, na sigla em inglês) e Michigan Hand Questionnaire (MHQ, na sigla em inglês) estão suscetíveis ao "efeito de teto", comparando com amostra de não-doentes; (2) determinar pontos de corte de performance diagnóstica e correlação interquestionários para DASH e MHQ em ambas as amostras. Método Estudo prospectivo, comparativo e não randomizado. Incluímos 150 pacientes, 75 no grupo caso (com doença) e 75 no grupo controle (sem doença). Trata-se de amostra de pacientes recém-admitidos em ambulatório de cirurgia da mão. Os controles foram pareados de forma balanceada de acordo com a inclusão dos casos. Determinamos a presença de efeito de teto por meio da taxa de respostas máximas (> 15%) e associamos curvas receiver operating characteristic (ROC, na sigla em inglês) para a determinação de pontos de corte para a determinação de doentes, associados a medidas de sensibilidade e especificidade. Consideramos p < 0.05 para significância estatística. Resultados Os questionários DASH e MHQ não demonstraram o efeito de teto para o grupo com doença. A porcentagem de pacientes do grupo caso com nota máxima foi de n = 18 (24%) no DASH e de 0% no MHQ. Para o grupo sem doença, 1 (1,33%) dos participantes pontuou com nota máxima para DASH, enquanto nenhum pontuou para o MHQ. Na determinação de casos, escores de DASH de 7,1 apresentam sensibilidade de 80% e especificidade de 60,3%. Para o MHQ, um escore de 76,9 apresenta sensibilidade de 56,2% e especificidade de 97,3%. Conclusão Os questionários DASH e MHQ são ferramentas confiáveis na mensuração do impacto das morbidades das mãos e dos punhos nas atividades diárias dos pacientes e não são suscetíveis a efeito de teto. O questionário DASH é mais sensível para a identificação de doentes, enquanto o MHQ é mais específico. Em situações nas quais se espera um incremento funcional mais discreto (ou mais específico), o MHQ parece mais adequado.

WALANT versus intravenous regional anesthesia for carpal tunnel syndrome: a randomized clinical trial

ABSTRACT BACKGROUND: There are several anesthetic techniques for surgical treatment of carpal tunnel syndrome (CTS). Results from this surgery using the "wide awake local anesthesia no tourniquet" (WALANT) technique have been described. However, there is no conclusive evidence regarding the effectiveness of the WALANT technique, compared with the usual techniques. OBJECTIVE: To evaluate the effectiveness of the WALANT technique, compared with intravenous regional anesthesia (IVRA; Bier's block), for surgical treatment of CTS. DESIGN AND SETTING: Randomized clinical trial, conducted at Hospital Alvorada Moema and the Discipline of Hand Surgery, Universidade Federal de São Paulo (UNIFESP), São Paulo (SP), Brazil. METHODS: Seventy-eight patients were included. The primary outcome was measurement of perioperative pain through a visual analogue scale (VAS). The secondary outcomes were the Boston Questionnaire score, Hospital Anxiety and Depression Scale (HADS) score, need for use of analgesics, operating room times, remission of paresthesia, failures and complications. RESULTS: The WALANT technique (n = 40) proved to be superior to IVRA (n = 38), especially for controlling intraoperative pain (0.11 versus 3.7 cm; P < 0.001) and postoperative pain (0.6 versus 3.9 cm; P < 0.001). Patients spent more time in the operating room in the IVRA group (59.5 versus 46 minutes; P < 0.01) and needed to use more analgesics (10.8 versus 5.7 dipyrone tablets; P = 0.02). Five IVRA procedures failed (5 versus 0; P = 0.06). CONCLUSIONS: The WALANT technique is more effective than IVRA for CTS surgery.

Onset of Trigger Finger after Carpal Tunnel Syndrome Surgery: Assessment of Open and Endoscopic Techniques.

Objective The present study aimed to determine the frequency of trigger finger (TF) onset after surgery for carpal tunnel syndrome (CTS) using an open (OT) or an endoscopic technique (ET). As a secondary endpoint, the present study also compared paresthesia remission and residual pain rates in patients submitted to both techniques. Methods Trigger finger onset and remission rates of paresthesia and pain at the median nerve territory was verified prospectively in a series of adult patients submitted to an OT procedure ( n = 34). These findings were compared with a retrospective cohort submitted to ET ( n = 33) by the same surgical team. Patients were evaluated with a structured questionnaire in a return visit at least 6 months after surgery. Results Sixty-seven patients were evaluated. There was no difference regarding trigger finger onset (OT, 26.5% versus ET, 27.3%; p = 0.94) and pain (OT, 76.5% versus ET, 84.8%; p = 0.38). Patients submitted to OT had fewer paresthesia complaints compared with those operated using ET (OT, 5.9% versus ET, 24.2%; p = 0.03). Conclusions In our series, the surgical technique did not influence trigger finger onset and residual pain rates. Patients submitted to OT had less complaints of residual postoperative paresthesia.

Resumo Objetivo Determinar a frequência do aparecimento de dedo em gatilho (DG) no pós-operatório da síndrome do túnel do carpo (STC) em duas técnicas: aberta (TA) e endoscópica (TE). Como desfecho secundário, comparar as taxas de remissão da parestesia e dor residual entre as duas técnicas. Métodos De forma prospectiva, verificamos o aparecimento de dedo em gatilho e taxa de remissão da parestesia e dor no território do nervo mediano em série de pacientes adultos operados pela TA (n = 34). Comparamos com coorte retrospectiva operada pela TE (n = 33), pela mesma equipe de cirurgiões. A avaliação dos pacientes ocorreu por meio de questionário estruturado em consulta de retorno, com mínimo de 6 meses de pós-operatório. Resultados Sessenta e sete pacientes foram avaliados. Não houve diferença quanto ao aparecimento de dedo em gatilho (TA, 26,5% versus TE, 27,3%; p = 0,94) e dor (TA, 76,5% versus TE, 84.8%; p = 0,38). Os pacientes operados pela TA apresentaram menos queixas de parestesia do que os operados pela TE (TA 5,9% versus TE 24,2%; p = 0,03). Conclusões Em nossa série, a técnica cirúrgica não influenciou o aparecimento de dedos em gatilho e dor residual. Os pacientes operados pela técnica aberta apresentaram menos queixa de parestesia residual pós-operatória.

Tratamento imediato da dor e limitação de abertura bucal nas disfunções temporomandibulares, através da Medicina Tradicional Chinesa (MTC) / Immediate treatment of pain and limitation of mouth opening in temporomandibular disorders through Traditional Chinese Medicine (TCM)

Disfunção Temporomandibular (DTM) apresenta-se como principal causa de dores orofaciais de origem não dentária. A acupuntura é indicada para o alívio de da dor em casos de DTM muscular, baseada em propriedades anti-inflamatórias com efeitos neuro-hormonais. Objetivou-se nesta pesquisa a avaliação da eficácia da acupuntura como um método válido para redução imediata da sintomatologia dolorosa e limitação de abertura bucal nos casos de DTM. Realizou-se terapia acupuntural em 30 pacientes com DTM, avaliando-se a dor, a partir da Escala Verbal (EV) e da Escala Analógica Visual (EAV) e a limitação de abertura bucal com o auxílio de paquímetro digital antes e após a terapia para registro da análise. O aumento da média de abertura bucal foi de 9,2% no total de participantes. Quanto à sintomatologia dolorosa, apresentou redução média em 63%. Na EV, 27 dos pacientes tiveram resposta "moderada" e "intensa" para sensação dolorosa. Contudo, após a terapia, observou-se ausência de sensação dolorosa intensa. Os dados apontaram significância da terapia acupuntural para redução dor e limitação de abertura bucal, de forma imediata, em pacientes com DTM... (AU)

Temporomandibular Disorder (TMD) is the main cause of orofacial pain of non-dental origin. Acupuncture is indicated for pain relief in cases of muscle TMD, based on anti-inflammatory properties with neuro hormonal effects. The aim of this research was to evaluate the effectiveness of the acupuncture as a valid method for immediate reduction of painful symptoms and mouth opening limitation in TMD cases. Acupuncture therapy was performed in 30 patients with TMD, evaluating pain from the Verbal Scale (VE) and Visual Analog Scale (VAS) and mouth opening limitation with the aid of a digital caliper before and after therapy to record the analysis. The increase in the average mouth opening was 9.2% in the total number of participants. As for painful symptoms, an average reduction of 63%. In IV, 27 of the patients had "moderate" and "intense" responses to painful sensation. However, after therapy, the absence of intense painful sensation was observed. The data showed the significance of acupuncture therapy for immediate pain reduction and mouth opening limitation in patients with TMD... (AU)

Nonsurgical Treatment for Symptomatic Carpal Tunnel Syndrome: A Randomized Clinical Trial Comparing Local Corticosteroid Injection Versus Night Orthosis.

PURPOSE: For carpal tunnel syndrome (CTS), local corticosteroid injection (corticosteroid), and/or wrist immobilization with night orthosis (orthosis) are commonly prescribed and are supported by strong evidence. The aim of this study was to compare orthosis versus corticosteroid for patients with CTS. METHODS: A CTS diagnosis was made clinically and supported by electrodiagnostic study. Patients were randomly allocated to either orthosis or corticosteroid. Clinical assessments were performed before the intervention, within the first week of the intervention, and 1, 3, and 6 months after the intervention. Primary outcomes were improvement in nocturnal paresthesia and Boston-Levine questionnaire (BLQ) score. Secondary outcomes were pain assessed by visual analog scale and complications. RESULTS: Of 100 patients enrolled in the study, 95 completed the planned follow-up (45 in the orthosis arm and 50 in the corticosteroid arm). Corticosteroid injections were superior to orthosis in remission of nocturnal paresthesia (remission rates at 1 month, 84.6% versus 43.83%; 3 months, 71.1% versus 40.4%; and 6 months, 80.3% versus 28.8%). The BLQ scores (functional and symptom subscales) were also more favorable for corticosteroid at 1, 3, and 6 months (minimal clinically important differences for Function > 0.5 and Symptom > 0.16). Pain scores were lower and favored the corticosteroid group. There were no complications in either group. CONCLUSIONS: Both options are effective in the short term. Corticosteroid is superior to orthosis for improving CTS-related nocturnal paresthesia, BLQ scores, and pain. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

Percutaneous Fixation without Bone Graft for Scaphoid Nonunion.

Objective To describe the clinical and radiographic outcomes of patients submitted to percutaneous fixation without bone graft for scaphoid nonunion, with a minimum follow-up of six months. Methods A case series study of a convenience sample of hand surgeons with prospective evaluation. Patients with scaphoid (waist or proximal pole) nonunion and the following features were included: more than six months of history; X-rays showing sclerosis of the edges of the nonunion, with resorption of the nonunion focus measuring less than 4 mm (Slade & Gleissler I, II, III and IV) and no angular deformity; and no proximal pole necrosis on magnetic resonance imaging (MRI). Results After six months of follow-up, all nonunion were consolidated, with no major complications. The functional outcomes revealed good scores on the disabilities of the arm, shoulder and hand (DASH; n = 12; mean: 6.9; standard deviation [SD]: 2.1) and patient-rated wrist evaluation (PRWE; n = 12; mean: 7.97, SD: 1.5) questionnaires. The results of the visual analog scale (VAS) showed little residual pain (n = 12; mean: 0.71; SD: 0.2). Slight decreases in flexion (69 versus 59.1; p = 0.007), extension (62.4 versus 48.7; p = 0.001) and radial deviation (29.6 versus 24.6; p = 0.014) were detected in comparison to the contralateral side. Conclusions All cases in the series presented consolidation and good functional scores at the six-month evaluation. This is a promising option (with lower technical demand and morbidity) for the treatment of scaphoid nonunion. Comparative studies are required to assess the effectiveness of this technique in comparison with other options.

Percutaneous Fixation without Bone Graft for Scaphoid Nonunion / Fixação percutânea sem enxerto ósseo para pseudartrose do escafóide

Abstract Objective To describe the clinical and radiographic outcomes of patients submitted to percutaneous fixation without bone graft for scaphoid nonunion, with a minimum follow-up of six months. Methods A case series study of a convenience sample of hand surgeons with prospective evaluation. Patients with scaphoid (waist or proximal pole) nonunion and the following features were included: more than six months of history; X-rays showing sclerosis of the edges of the nonunion, with resorption of the nonunion focus measuring less than 4 mm (Slade & Gleissler I, II, III and IV) and no angular deformity; and no proximal pole necrosis on magnetic resonance imaging (MRI). Results After six months of follow-up, all nonunion were consolidated, with no major complications. The functional outcomes revealed good scores on the disabilities of the arm, shoulder and hand (DASH; n = 12; mean: 6.9; standard deviation [SD]: 2.1) and patient-rated wrist evaluation (PRWE; n = 12; mean: 7.97, SD: 1.5) questionnaires. The results of the visual analog scale (VAS) showed little residual pain (n = 12; mean: 0.71; SD: 0.2). Slight decreases in flexion (69 versus 59.1; p = 0.007), extension (62.4 versus 48.7; p = 0.001) and radial deviation (29.6 versus 24.6; p = 0.014) were detected in comparison to the contralateral side.

Resumo Objetivo Descrever os resultados clínico-radiográficos de pacientes tratados por meio de fixação percutânea sem enxerto ósseo para pseudartrose do escafóide, com seguimento mínimo de seis meses. Métodos Série de casos de uma amostra de conveniência de grupo de cirurgiões de mão com avaliação prospectiva.. Foram incluídos pacientes com diagnóstico de pseudartrose do escafóide (cintura ou polo proximal) com as seguintes características: mais de seis meses de histórico; radiografias demonstrando esclerose das bordas da pseudartrose, com reabsorção do foco de pseudartrose menor do que 4 mm (Slade & Gleissler I, II, III e IV), sem deformidade angular; e sem necrose do polo proximal pela ressonância magnética (RM). Resultados Na avaliação com mais de seis meses, todas as pseudartroses estavam consolidadas e sem maiores complicações. Os resultados funcionais demonstraram boas pontuações nos questionários de disfunções do braço, ombro e mão (disabilities of the arm, shoulder and hand, DASH; n = 12; média: 6,9; desvio padrão [DP]: 2,1) e de avaliação do punho pelo paciente (patient-rated wrist evaluation, PRWE; n = 12; média: 7,97; DP: 1,5). Observou-se pouca dor residual de acordo com a escala visual analógica (EVA; n = 12; média: 0,71; DP: 0,2). Houve discreta diminuição da flexão (69 versus 59,1; p = 0,007), da extensão (62,4 versus 48,7; p = 0,001) e do desvio radial (29,6 versus 24.6; p = 0,014) em comparação ao lado contralateral. Conclusões Nesta série, todos os casos estavam consolidados ao sexto mês de avaliação, com bom status funcional. Trata-se de uma opção promissora (menor demanda técnica e morbidade) para o tratamento da pseudartrose do escafóide. Estudos comparativos serão úteis para avaliar a efetividade da técnica com relação a outras opções.

Acute handlebar syndrome: Two extremes of a challenging diagnosis.

BACKGROUND: Ulnar nerve mononeuropathy diagnosis can be challenging depending on where neural lesion is present. Repetitive trauma during cycling is a rare cause of ulnar neuropathy. CASE DESCRIPTION: We describe two patients who developed the handlebar syndrome, an ulnar nerve palsy at Guyon's canal after cycling. The first patient had the syndrome after a short-distance ride and she was treated surgically, while the second patient developed the classical syndrome after a long ride and received conservative treatment. Surgical treatment of the first patient led to functional recovery. CONCLUSION: Handlebar syndrome is a neuropathy caused by extrinsic repetitive compression of ulnar nerve at wrist. Increasing incidence of this disease can be expected after increasing popularity of cycling sports. Avoid of repetitive trauma is the main management goal, with surgical treatment reserved for failure of conservative treatment.

Assessment of the Effects of Swimming as a Postoperative Rehabilitation on Nerve Regeneration of Wistar Rats Submitted to Grafting of Autologous Nerves after Injury to the Sciatic Nerve.

Objective To evaluate the effects of swimming on nerve regeneration after sciatic nerve injury in Wistar rats. Methods A total of 30 Wistar rats was divided into 3 groups: Sham + Nat group animals that were not submitted to graft surgery and were submitted to swimming ( n = 10); Graft group: animals submitted to autologous sciatic nerve graft ( n = 10); and Graft + Nat group: animals submitted to autologous sciatic nerve graft surgery and to swimming ( n = 10). The results were analyzed on the software (GraphPad Software, San Diego, CA, USA). Results In the first evaluation, all sciatic functional index (SFI) values were similar ( p = 0.609). Thirty days after the surgical procedure, we observed differences between all the comparisons: Sham + Nat (-34.64 ± 13.89) versus Graft (-145.9 ± 26.06); Sham + Nat versus Graft + Nat (-89.40 ± 7.501); Graft (-145.9 ± 26.06) versus Graft + Nat (-89.40 ± 7.501). In the measurements (60 and 90 days), there was no statistical difference between the Graft and Graft + Nat groups, with significantly lower values in relation to the control group ( p < 0.001). The number of motor neurons presented differences in the comparisons between the Sham + Nat and Graft groups (647.1 ± 16.42 versus 563.4 ± 8.07; p < 0.05), and between the Sham + Nat and Graft + Nat groups (647.1 ± 16.42 versus 558.8 ± 14.79; p < 0.05). There was no difference between the Graft and Graft + Nat groups. Conclusion Animals submitted to the swimming protocol after the sciatic nerve grafting procedure did not present differences in the SFI values and motor neuron numbers when compared to the control group. Therefore, this type of protocol is not efficient for the rehabilitation of peripheral nerve lesions that require grafting. Therefore, further studies are needed.

Prevalence of the Linburg-Comstock Anomaly in a Brazilian Population Sample.

Objective To determine the prevalence of the Linburg-Comstock anomaly in a Brazilian population sample. Methods A cross-sectional observational study was carried out between October 2017 and April 2018. We included male and female volunteers aged 18 years or older. The presence of the Linburg-Comstock anomaly was determined by performing the clinical tests described by Linburg and Comstock. The data were analyzed using the GraphPad Prism software, and we considered differences with p < 0.05. Results The study analyzed 1,008 volunteers (2,016 hands) with a mean age of 38.3 years, 531 (52.67%) of which were male, and 477 (47.33%) were female. The Linburg-Comstock anomaly was diagnosed in 564 (55.95%) individuals, and it was bilateral in 300 (53.2%) of them, right-sided in 162 (28.72%), and left-sided in 102 (18.08%). No significant differences were found when comparing the prevalence between genders. However, a the prevalence of the right-sided anomaly in the male population (n = 99; 70.21%) was higher than in the female one (n = 63; 51.21%), with p = 0.0016. In addition, the presence of pain by the maneuver described by Linburg and Comstock was more prevalent in women (n = 150; 54.94%) than in men (n = 105; 36.08%), with p = 0.0001. These results show the importance of epidemiological studies on the Linburg-Comstock anomaly, mainly in order to investigate the presence of associated conditions. Conclusion The prevalence of the Linburg-Comstock anomaly in the studied population was of 55.95%, and it was bilateral in 53.2% of the volunteers. The presence of the connection was observed more frequently in the right side and among men, but the pain symptom was more frequent among women.
