Arterite actínica de artéria subclávia: relato de caso e revisão de literatura

Diversas são as complicações possíveis da radioterapia na adjuvância do tratamento de neoplasias. Lesões actínicas de artéria subclávia em pacientes submetidos a este tipo de tratamento para neoplasia de mama são complicações conhecidas, porém com poucos relatos de casos publicados. No presente relato, descrevemos um caso de oclusão de artéria subclávia direita em paciente submetida à radioterapia para tratamento de neoplasia de mama, tratada com a revascularização convencional, com interposição de enxerto de politetrafluoretileno (PTFE). Na revisão da literatura realizada, foram encontrados doze casos descritos que evidenciaram diferentes opções terapêuticas. Concluímos que a arterite actínica de artéria subclávia é uma doença incomum, entretanto sua hipótese deve ser aventada em todos os pacientes com isquemia de membro superior já submetidos a tratamento de radioterapia.

Modified constraint-induced movement therapy and modified forced-use therapy for stroke patients are both effective to promote balance and gait improvements

Background: Previous studies show that chronic hemiparetic patients after stroke, presents inabilities to perform movements in paretic hemibody. This inability is induced by positive reinforcement of unsuccessful attempts, a concept called learned non-use. Forced use therapy (FUT) and constraint induced movement therapy (CIMT) were developed with the goal of reversing the learned non-use. These approaches have been proposed for the rehabilitation of the paretic upper limb (PUL). It is unknown what would be the possible effects of these approaches in the rehabilitation of gait and balance. Objectives: To evaluate the effect of Modified FUT (mFUT) and Modified CIMT (mCIMT) on the gait and balance during four weeks of treatment and 3 months follow-up. Methods: This study included thirty-seven hemiparetic post-stroke subjects that were randomly allocated into two groups based on the treatment protocol. The non-paretic UL was immobilized for a period of 23 hours per day, five days a week. Participants were evaluated at Baseline, 1st, 2nd, 3rd and 4th weeks, and three months after randomization. For the evaluation we used: The Stroke Impact Scale (SIS), Berg Balance Scale (BBS) and Fugl-Meyer Motor Assessment (FM). Gait was analyzed by the 10-meter walk test (T10) and Timed Up & Go test (TUG). Results: Both groups revealed a better health status (SIS), better balance, better use of lower limb (BBS and FM) and greater speed in gait (T10 and TUG), during the weeks of treatment and months of follow-up, compared to the baseline. Conclusion: The results show mFUT and mCIMT are effective in the rehabilitation of balance and gait. Trial Registration ACTRN12611000411943.
