Use of Stationary Ultrasound Device In Subcutaneous Abdominal Fat Tissue: Analysis of Clinical Effects.

Background: High-intensity stationary therapeutic ultrasound (HITU) technology is gaining popularity as an attractive modality for treating different conditions, but little is known about its application in aesthetics. Objective: To analyze the effects of stationary unfocused ultrasound (HITU technology) in treating localized fat in women's abdominal region. Methods: The sample consisted of 43 women with localized abdominal adiposity, assessed pre and post-treatment by assessment protocols, adversity analysis questionnaires, ultrasound exams, and serum level exams. The volunteers were randomly divided into three subgroups: G-1, who used the device off, G-2 received therapy with the device once a week for two months (Parameters: Pulsed - 100Hz - 50% - 4.0 W/cm2 - 20 minutes) and the G-3 who used the device on twice a week for a month (Parameters: Pulsed - 100Hz - 50% - 3.2W/cm2 - 30 minutes). All groups received eight sessions in total. Results: There was a significant reduction for G-3 in the plicometry of the lower right region (p=0.01) in the comparison between the final and initial moments. In the comparison among the three research groups, there was a significant reduction in plicometry in the lower right (p=0.03) and left (p=0.02) regions in G3. Via ultrasound, a reduction in the fat layers average was observed in all groups. In G-3, there were significant differences in the left infraumbilical region (p=0.02) and right (p=0.04). In the group comparison, the right infraumbilical region showed significant differences (p=0.04) for the G-3. No differences were found for weight, BMI, body fat percentage and supra, infra and umbilical perimetry (p>0.05). The adverse reactions reported were: Mild hyperaemia (75%) and sensation of shock (21%), there were also reports of improvement in fluid retention in 93.7 percent of the volunteers, and most were satisfied with the result. Conclusion: Both treatment protocols for the reduction of localized adiposity were effective compared to the placebo group, with a significant reduction in the use of ultrasound and plicometry in the concentration of fat in the lower abdominal region.

Effects of Ultracavitation and Radiofrequency on Abdominal Adiposity.

Background: The mechanism of fat reduction from radiofrequency occurs via the thermal stimulation of adipocyte metabolism, causing a lipase-mediated triglyceride enzyme degradation, apoptosis, and adipocyte rupture. Ultracavitation promotes fat reduction using adipose cell destruction through mechanical stimulus. The literature on the combination of these two physical agents, named ultrafrequency, is still scarce and requires consistent analysis of the effects of this therapy combination. Objective: The objective of this study was to investigate the effects of radiofrequency associated with ultracavitation in the treatment of abdominal subcutaneous tissue of women. Methods: This was a prospective, randomized clinical trial in which 45 participants were divided into three distinct groups: the control group (no treatment); ultracavitation group; and ultracavitation and radiofrequency (UCV+RF) group, each with 15 volunteers. The following variables were evaluated: weight, perimetry, plicometry, ultrasonography, treatment reactions, and patient satisfaction. Results: The participants in the UCV+RF group presented a more significant decrease in adipose tissue, which was verified through all the evaluation methods. Conclusion: Based on our results, the simultaneous application of ultracavitation and radiofrequency generated a reduction in localized adiposity superior to the isolated use of ultracavitation.

Analysis of immediate use of sunscreen after microneedling.

INTRODUCTION: Microneedling promotes skin microlesions that lead to an inflammatory process, increasing cell proliferation, cell metabolism, and synthesis of collagen and elastin, therefore restoring skin integrity. OBJECTIVE: This study aims to investigate the differences between the physical and the physical-chemical sunscreen application after microneedling, assessed through histological analysis. METHOD: This was a two-phase study. The first phase investigated the physical and physical-chemical sunscreen penetration mixed with India ink through histological analysis. The sunscreens were applied after the microleakage in vivo on the skin of a volunteer who underwent abdominoplasty 24 hours after the procedure. Histological analyses were carried out using optical and electron microscopy. The second phase analysed the skin reactions with the use of physical sunscreen after different microneedling treatments. The sample consisted of 30 volunteers distributed into three groups: G1 received the "Roller" microneedling, G2 received pen micropuncture treatment, and G3 received the fractional radiofrequency treatment. RESULTS: The histological analyses of the first phase indicated that the physical-chemical protection sunscreen penetrated more deeply, and pigment was found among the collagen fibres and the dermal fibroblast cytoplasm in comparison to the physical protection sunscreen, which had the pigment confined exclusively in the superficial epidermis layer. The second phase results demonstrated that the use of the physical protection sunscreen after the different microneedling techniques showed no adverse reactions such as itching, pain or soreness, and the hyperaemia. CONCLUSION: The proposed intervention showed that the use of physical protection sunscreen after different microneedling procedures is safe.

Situação microbiológica dos transdutores piezoelétricos ultra-sônicos terapêuticos nos serviços de fisioterapia da Baixada Fluminense, Rio de Janeiro, Brasil / Microbiological situation of piezoeletric transducers therapeutical ultra sound at physiotherapy's service of Baixada Fluminense, Rio de Janeiro, Brasil

A terapia ultra-sônica caracteriza-se por ondas sonoras de alfa freqüência. O ultrasom subdivide-se em duas partes, o transdutor piezoelétrico e a corrente elétrica, sendo o último responsável por realizar a conversão de energia bruta em corrente elétrica alternada constante, que é transpassada pelo transdutor ao paciente. A técnica de aplicação do estímulo ultra-sônico expõe o transdutor em contato com o tecido afetado a ser tratado. Este fato identifica o equipamento e sua técnica de aplicações como possíveis veiculadores de bioagentes patogênicos. Os transdutores piezoelétricos ultrassônicos, de tamanho e marcas diversificadas, utilizados em pacientes foram submetidos à fricção circular com suabe embebido em soluções salina na área efetiva de radiação. No tempo de duas horas após a coleta foram semeados em meio de cultura de Brewer e Sabouraud. O crescimento obtido foi repicado para meios Agar-sangue, Agar-hipertônico-manitol e meio seletivo para gêneros Pseudomonas e Staphylococcus. A identificação foi feita por caracteres culturais e provas bioquímicas – Sistema BioMerieux Vitek. O crescimento fúngico foi identificado por caracteres morfológicos, culturais, provas bioquímicas e sorológicas, quando necessárias. Os resultados apontaram 65% de positividade nas amostras avaliadas com presença de agentes fúngicos e bacetrianos. A maior freqüência coube aos elementos fúngicos (40%) seguido de bacterianos (25%). Sugere-se necessidade de prevenção de transmissão de bioagentes por contato e melhora na qualidade do atendimento em fisioterapia.

Ocorrência de bioagentes patogênicos nos eletrodos utilizados na Estimulação Nervosa Elétrica Transcutânea nos serviços de fisioterapia da Baixada Fluminense RJ / Occurrence of pathogenic bioagents on electrodes used in Transcutaneous Nerve Stimulation in physical therapy services in Baixada Fluminense RJ

A Estimulação Nervosa Elétrica Transcutânea (TENS) é uma corrente de baixa intensidade, onde o contato entre o eletrodo e a pele são mecanismos indispensáveis da técnica terapêutica. Os eletrodos são constituídos de borracha siliconizada, acoplados à superfície cutânea com o uso de um gel eletricamente condutivo. Esses eletrodos de tamanho e marcas diversificadas, utilizados em pacientes, foram submetidos à fricção longitudinal com o auxílio de um suabe, em um tempo máximo de duas horas e foram semeados em meio de cultura Brewer e Sabouraud. O crescimento obtido foi repicado para meios de cultura Agar-sangue, Agar-hipertônicomanitol e meio seletivo para Pseudomonas e Staphylococcus. As colônias foram identifi cadas por caracteres culturais e provas bioquímicas de identifi cação, através de sistema BioMerieux Vitek. O crescimento fúngico foi identificado por caracteres morfológicos, culturais, provas bioquímicas e morfológicas quando necessárias. Os resultados demonstraram 59,5 % de positividade nas amostras avaliadas para a presença de agentes fúngicos e bacterianos. Sugere-se uma necessidade de prevenção da transmissão de bioagentes por contato, e melhoria na qualidade do atendimento em fisioterapia.
