Introdução: A terapia de ondas de choque piezoelétrica (TOC) é uma técnica não invasiva que visa a reduzir o tecido adiposo subcutâneo localizado. Objetivos: Investigar os efeitos da terapia ondas de choque piezoelétrica na redução da adiposidade subcutânea localizada. Métodos: Efetuou-se um estudo experimental, com 31 participantes, de 25 a 45 anos, do sexo feminino. Foram realizadas quatro sessões de tratamento, uma vez por semana com parâmetros da OC piezoelétrica. Procedeu-se à aplicação dinâmica na região infraumbilical; e estacionária, na supraumbilical, ambas no lado esquerdo. O lado direito não recebeu aplicação, tornando-se o lado controle. Resultados: Na aplicação da TOC piezoelétrica na forma estacionária, houve maior redução de tecido adiposo do que no modo dinâmico. Conclusão: Pode-se observar que a terapia por OC piezoelétrica promoveu uma redução da adiposidade localizada, com o modelo de equipamento escolhido e na dose proposta neste estudo, constatada nas análises de plicometria e ultrassonografia.

Introduction:The pressurized intradermotherapy is a needle-free technology whose function is the release of medicated or cosmetological actives in the skin and the subcutaneous tissue using mechanical force, gaspressure, and shockwaves, allowing the treatment of different aesthetic changes. Objective: To investigate the effects of intradermotherapy with a pressurized injection system in thetreatment of localised abdominal fat in women. Method: The sample consisted of 30 women with localized adiposity in the abdominal region, evaluated before and after treatment through evaluation protocols and ultrasound examinations. The volunteers were randomly distributed in to two subgroups: Pressurized intradermotherapy group (G01), to which were an adipolytic substance, a combination of different drugs, was applied, and the control group (CG), which received an injectable saline solution only. Both groups underwent four biweekly treatment sessions. Results: The fat layer analysis 60 days after the initial application showed a significant reduction of the measurements in the comparison between groups G01 and GC; the plicometry showed a significant difference on the right side (p = 0.04) and the left side (p = 0.04); in the supraumbilical (p = 0.001) and infra umbilical (p = 0.03) perimetries. Two months after the beginning of treatment, the ultrasound examination two showed a significant reduction on the sides: right (p = 0.03) and left (p = 0.03); however, no differences in weight were found (p>0.05). Conclusion:The treated group presented a significant fat layer reduction after the treatment with the pressurised intradermotherapy protocol, with better results after the fourth application.

Introduction: Cryofrequency is a novel therapy which was developed with the combination of cold (cryotherapy) and heat (radiofrequency) application, causing a thermal shock effect on skin tissue. The thermal shock is believed to alter local metabolism. Objective: To investigate the effect of cryofrequency on the skin tissue of a mini pig in an in vitro and in vivo experimental model. Methodology: A small swine of the S. domesticus species, a male mini-pig (30 kg weight) was elected for the in vivo procedure subject. The in vitro step was performed on the extracted abdominal part of another subject of the same species and breed. Then, after the application of cryofrequency in the monopolar and bipolar form in vivo, a histological analysis was performed.Results: A higher temperature variation was observed comparing the pilot study in vitro with respect to the experimental one in vivo. Microscopically, an increase of collagen fibers and blood supply and decreased adipose tissue was observed after cryofrequency application. Conclusion: With the bipolar cryofrequency, no reduction of adipose tissue was observed, but regarding the connective tissue, extensive areas of collagen deposition were observed, as well as a great amount of new-formed collagen fibers.
