Long-wave infrared radiation reflected by compression stockings in the treatment of cellulite: a clinical double-blind, randomized and controlled study.

BACKGROUND: Cellulite refers to changes in skin relief on the thighs and buttocks of women, with a prevalence of 80-90%, causing dissatisfaction and search for treatment. Etiopathogenesis is multifactorial, as follows: herniation of the hypodermis towards the dermis, facilitated by perpendicular fibrous septa, changes in the dermal extracellular matrix, decreased adiponectin, genetic polymorphism, microcirculation alterations and inflammatory process. There are numerous therapeutic approaches, with little evidence of effectiveness. The long-wave infrared (LWIR) radiation interacts with water, improves microcirculation and stimulates metabolic processes. To date, the use of tissues with potential reflection of LWIR radiation has not been systematically investigated as adjuvant treatment for cellulite. OBJECTIVE: To investigate the efficacy and safety of the treatment of cellulite through the use of compression stockings made with thread reflecting LWIR radiation. PATIENTS AND METHODS: Clinical study of therapeutic intervention, controlled and double-blind, including 30 women, aging from 25 to 40 years, with cellulite of grades II and III on the thighs and buttocks who used compression stockings, "pantyhose" model, made with reflector thread of LWIR radiation, on only one randomized side. Women under other treatments for cellulite and with venous and/or blood insufficiencies were excluded. Evaluation of efficacy by clinical parameters, photographs, Dermatology Life Quality Index (DLQI), cutometry and high frequency ultrasonography and security by observation of adverse events and venous EcoDoppler recordings. RESULTS: DLQI scores showed significant reduction; the two-dimensional high-frequency ultrasonography showed an insignificant increase in dermal echogenicity as well as other efficacy parameters demonstrated no or slight improvement, with no differences between the sides exposed or not to LWIR; and there were no severe adverse events. CONCLUSION: Compression stockings, with or without thread reflector of LWIR, showed slight effects in the appearance of cellulite, but the treatment determined a positive impact on women quality of life.

Fatores preditores do alcance das metas de um programa de intervenção em nipo-brasileiros / Predictors of goal achievement in an intervention program among Japanese-Brazilians

Identificar fatores da linha de base preditores do alcance das metas do programa de intervenção no estilo de vida após 12 meses em população de nipo-brasileiros, empregando-se modelos de regressão logística ajustados. Em 2005, 321 participantes eram portadores de excesso de peso e houve maior chance [OR (IC95 por cento)] de alcance da meta de perda de peso após 12 meses entre mulheres [2,45 (1,33; 4,13)], indivíduos de maior idade [1,03 (1,00; 1,06)] e menor chance entre portadores de morbidades no início do estudo [0,33 (0,14; 0,77)]. Dos 261 indivíduos sedentários, o alcance da meta de atividades físicas foi inversamente relacionado ao exercício de atividades profissionais [0,40 (0,17; 0,95)]. Não se verificou fatores da linha de base associados ao alcance das metas do consumo de legumes, verduras e frutas e gorduras saturadas da dieta após 12 meses. Indivíduos de maior idade, mulheres, não portadores de morbidades e sem exercício de atividades profissionais na linha de base apresentaram maior chance de alcance das metas após 12 meses de intervenção no estilo de vida.

The aim of this study was to identify baseline factors associated with achieving goals after a 12-month lifestyle intervention program in a Japanese-Brazilian population, using adjusted logistic regression models. In 2005, 321 participants were overweight. The odds [OR (IC95 percent)] of reaching the goals after 12 months of intervention were directly related to female gender [2.35 (1.34, 4.13)] and older age [1.03 (1.00, 1.06)] and inversely related to baseline morbidity [0.33 (0.14, 0.77)]. Of the 261 sedentary individuals, achieving the goal for physical activity was inversely related to working [0.44 (0.17, 0.95)]. No baseline predictors were found for reaching the goal of fruit and vegetable consumption or saturated fat intake after 12 months. At baseline, women, older individuals, and individuals without diseases or not working showed increased odds of achieving the goals after 12 months of the lifestyle intervention.

Complicaçöes do cateterismo arterial retrógrado percutâneo / Complications of percutaneous retrograde arterial catheterism

A introduçäo do cateterismo vascular pela técnica de Seldinger veio trazer um enorme avanço ao universo de exames complementares utilizados para diagnóstico na medicina. Entretanto, sendo uma técnica invasiva, esse procedimento poderia causar complicaçöes. Com o objetivo de analisar as complicaçöes envolvidas com a utilizaçäo dessa técnica, estudamos 707 pacientes submetidos a 772 cateterismos arteriais retrógrados percutâneos para diagnóstico. Verificamos a ocorrência de 74 complicaçöes (9,6) sendo 16 consideradas graves (2,1) e 58 leves(7,5). O tratamento operatório foi instituido em 15 complicaçöes vasculares graves (1,9) e medicamentoso e/ou observaçäo clínica nas complicaçöes restantes. Näo ocorreram óbitos nessa amostra
