Effects of therapeutic ultrasound and paraffin with or without vacuum massage on biomechanical properties of grafted skin after burn: a randomized controlled trial

SUMMARY OBJECTIVE: This study aimed to compare the effects of therapeutic ultrasound and paraffin with or without vacuum massage on the biomechanical properties of grafted skin after a burn. METHODS: A total of 44 patients with deep second- and third-degree burns, with a mean age of 35.89 (±11.53) years, who visited the Hospital Burn Unity, were included in the study. The therapeutic interventions were randomly defined by drawing lots, with a crossover design (crossover), and a minimum interval of 7 days (washout) between interventions. Skin biomechanical parameters such as distensibility (R0) and viscoelasticity (R6) were noninvasively evaluated by Cutometer before and after 0, 10, 20, and 30 min of intervention with therapeutic ultrasound and paraffin alone, as well as associated with negative pressure therapy of the skin (vacuum therapy). In this study, all groups showed increased distensibility (R0) in the period immediately after the application of the resources and a progressive reduction in the effects in the consecutive tests. Participants with skin grafts showed a decrease in viscoelasticity (R6) in all groups, except therapeutic paraffin and therapeutic ultrasound and vacuum massage. CONCLUSION: The biomechanical properties of grafted skin after a burn are altered after therapeutic intervention with ultrasound alone or associated with vacuum massage, such as intervention with paraffin associated with vacuum massage, for both parameters evaluated, skin distensibility (R0) and skin viscoelasticity (R6). However, the same did not occur for the intervention with isolated paraffin. There was no significant difference between the interventions therapeutic ultrasound and therapeutic paraffin.

Adaptaçäo do aparelho de amplificaçäo sonora individual em perda auditiva unilateral: o ponto de vista do usuário / Adaptation of the individual hearing aid in the unilateral auditive loss: the usuary point of view auditive

Sä inúmeras as vantagens de audiçäo binaural, uma vez que proporciona melhor localizaçäo da fonte sonora, somaçäo binaural, eliminaçäo do efeito sombra da cabeça e, principalmente, melhora do reconhecimento de fala no ruído. Com base nesses fatos, ressaltamos a importância da adaptaçäo do aparelho de amplificaçäo sonora individual (AASI) nas deficiências auditivas unilaterais. Esse estudo teve como objetivo avaliar o desempenho do AASI nas diferentes situaçöes de vida diária, assim como, as possíveis queixas e satisfaçäo com a utilizaçäo do mesmo. Para issp, foi aplicado um questionário de auto-avaliaçäo em portadores de deficiência audutiva unilateral, de grau leve à profundo, usuários de AASI com tempo de adaptaçäo de seis meses a dois anos, atendidos no Centro de Distúrbios da Audiçäo, Linguagem e Visäo (CEDALVI), do Hospital de Reabilitaçäo de Anomalias Cranofaciais (HRACF-USP), em Bauru-SP. A maioria dos pacientes apontou o AASI como muito útil nas situaçöes diárias de comunicaçäo e encontravam-se satisfeitos com o uso do mesmo.
