INTRODUÇÃO: A prática baseada em evidências é necessária para que os pacientes recebam tratamentos eficazes, assim como para reduzir os custos de saúde em geral. Com o crescimento da produção científica com qualidade metodológica heterogênea, torna-se difícil para o fisioterapeuta selecionar quais as melhores evidências para embasar a sua conduta terapêutica. OBJETIVOS: Apresentar a base de dados PEDro (Physiotherapy Evidence Database). MATERIAIS E MÉTODOS: Foram descritos a abrangência da base de dados, tipos de estudos indexados, grau de acessibilidade aos usuários e critérios de qualificação metodológica, entre outras características. RESULTADOS: PEDro é a base de dados mais abrangente em estudos que testam a eficácia das intervenções fisioterapêuticas, em que são indexados estudos controlados aleatorizados, revisões sistemáticas e diretrizes de prática clínica, e os estudos controlados aleatorizados possuem sua qualidade metodológica e descrição estatística avaliadas por meio da escala de qualidade PEDro. A PEDro tem acesso livre e gratuito, facilitando o uso por profissionais, alunos da área e pesquisadores. Os resultados das buscas são ranqueados de acordo com a qualidade metodológica dos artigos encontrados. A PEDro está disponível em cinco idiomas: inglês, mandarim, francês, alemão e português e disponibiliza uma versão simples, sem termos técnicos, para consumidores de serviços de fisioterapia, que são as "escolhas fisioterapêuticas", ou physiotherapy choices. CONCLUSÃO: A PEDro cumpre o seu papel auxiliando tanto profissionais como pacientes, informando sobre as evidências de eficácia de tratamentos fisioterapêuticos de uma forma rápida e simples e contribuindo com o recolhimento de informações para subsidiar decisões ou escolhas terapêuticas.

Abstract

KT was effective on postmastectomy lymphedema related to breast cancer; however, it is not more efficient than other treatments.

Hemorrhagic shock/reperfusion (HS/R) followed by sepsis triggers systemic microcirculatory disturbances that may induce multiple organ failure. The present study evaluated the effects of HS/R and cecal ligation and puncture, followed by necrotic cecal resection/peritoneal lavage (REL) on leukocyte-endothelium interactions at the mesentery. Eighty-one anesthetized Wistar rats (200-250 g) were randomly assigned to a first injury: (1) control-HS-no hemorrhagic shock/no reperfusion group, (2) HS/blood-HS/R with 25% shed blood, and (3) HS/blood + LR-HS/R with 25% of the shed blood + lactated Ringer's solution, 3x shed blood volume. Twenty-four hours post-HS/R, animals were submitted to cecal ligation and puncture and, 24 h thereafter, to REL. Leukocyte-endothelium interactions were assessed by intravital microscopy and intercellular adhesion molecule (ICAM) 1 and P-selectin expression by immunohistochemistry. Lungs were observed for ICAM-1 expression and neutrophil infiltration. Single and double injury induced significant increases in rolling (approximately 2-fold), adherent (approximately 5-fold), and migrated leukocytes (approximately 7-fold); ICAM-1 expression (approximately 1/2-fold), and P-selectin expression (approximately 1/2-fold) at the mesentery compared with control-HS group. REL normalized leukocyte-endothelium interactions at the mesentery in single-injured animals. However, in double-injured rats, adherence and migration of leukocytes decreased but did not normalize. Similar results were observed on ICAM-1 expression and neutrophil infiltration in the lungs from these animals. In conclusion, the current in vivo observation of the mesenteric microcirculation after a double injury followed by REL is a suitable model for the systematic evaluation of the inflammatory reaction at local and distant sites. In addition, data presented herein emphasized the importance of surgical removal of the septic focus in controlling the otherwise lethal sepsis-induced multiple organ dysfunction syndrome.

Objective: This study was designed to evaluate the short-term efficacy of low-level laser therapy (LLLT) for improving pain and function in patients with knee osteoarthritis. Methods: Forty-seven patients with knee osteoarthritis (79 knees), of both genders, participated in this randomized controlled double-blind clinical trial. They were randomly allocated to two groups: laser group with 25 patients (41 knees) and placebo group with 22 patients (38 knees). LLLT was performed three times a week, totaling nine sessions, using a AsGa 904 nm laser with mean power of 60 mW and beam area of 0.5 cm2. Nine points were irradiated on the knee, with energy of 3.0 J/point. The placebo group was treated with the same laser device, but with a sealed probe. Evaluations using Lequesne, visual numerical scale (VNS), Timed Up and Go (TUG), goniometry and dynamometry were conducted before the treatment started and after the nine sessions of LLLT. Results: A significant improvement in pain and function was found in all the assessments applied to the laser group. On comparing the laser group with the placebo group, significant differences were found in the VNS-resting and Lequesne evaluations. Conclusion: Treatment with LLLT improves pain and function over the short term in patients with knee osteoarthritis.
