Low-level laser therapy modulates musculoskeletal loss in a skin burn model in rats

PURPOSE: To investigate the effectiveness of low-level laser therapy (LLLT) on gastrocnemius muscle morphology and Myod imunoexpression in a model of dorsal burn in rats. METHODS: Sixteen male Wistar rats were distributed into two groups: control group (CG): rats submitted to scald burn injury without treatment and laser treated group (LG): rats submitted to scald burn injury and treated with laser therapy. Fourteen days post-surgery, gastrocnemius muscle was evaluated being the specimens stained with HE and morphometric data was evaluated. MyoD expression was assessed by immunohistochemistry. RESULTS: The results showed that laser treated animals presented more organized tissue morphology compared to the non-treated animals, with a higher number of nucleus in the fibers. Also, the cross sectional area of the fibers and the MyoD immunoexpression in the laser treated groups was higher. CONCLUSION: Low-level laser therapy had positive effects on gastrocnemius muscle, improving tissue muscle morphology, increasing cross sectional area and MyoD immunoexpression.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Ministry of Science, Technology and Inovation National Council of Scientific and Technological Development Institutional Program for Scientific InitiationUNIFESP Bioscience DepartmentUNIFESP School of MedicineUNIFESP Postgraduate Program in Interdisciplinary Health SciencesUniversidade Federal de São Paulo (UNIFESP) Department of Human Movement SciencesUNIFESP, Bioscience DepartmentUNIFESP, School of MedicineUNIFESP, Postgraduate Program in Interdisciplinary Health SciencesUNIFESP, Department of Human Movement SciencesSciEL

Danazol a new perspective in the treatment of htlv-l associated myelopathy (preliminary report)

We investigated the efficacy of danazol treatment in eight patients with HTLV-l associated myelopathy/tropical spastic paraparesis (HAM/TSP). Treatment with danazol yielded clinical improvement of urinary control and gait disturbances in 7 out of the 8 patients. The improvement was noted within 15 days of danazol administration. Analysis of factors of relevance to the clinical improvement with danazol showed that the beneficial response was preferentially found in females

Mielopatias por HTLV-1 na cidade de Salvador, Bahia

Paraparesia espástica progressiva associada a HTLV-1 constitui-se em uma patologia com características endêmicas em várias regiões do Brasil. Em Salvador, 102 pacientes com mielopatias de diversas etiologias foram triados para HTLV-I/II com ELISA e Western blot em quatro hospitais gerais que assistem a população de baixa renda. Foram encontrados 36 pacientes com mielopatia associada a HTLV-I/II, o que está de acordo com a elevada prevalência dessa patologia em Salvador. Todos os pacientes com infecção pelo HTLV-I/ II apresentavam paraparesia espástica progressiva, bexiga neurogênica associada, a graus variáveis de comprometimento sensitivo superficial e/ou profundo e síndrome do neurônio motor inferior. O exame de LCR mostrou pleocitose linfocitária com aumento moderado de gama-globulinas e a ressonância magnética mostrou graus variáveis de lesões periventriculares e subcorticais associadas ou não a atrofia da medula espinal torácica. O exame neurológico e os dados de ressonância magnética sugerem que os pacientes com comprometimento neurológico por HTLV-I podem estar acometidos por graus variáveis de leucoencefalomieloneuropatia
