ABSTRACT
Abstract Purpose To collect data capable of pointing out the effects of the ultracavitation treatment on the liver of rabbits after adipose tissue application, by means of histological analyses of the liver and hematological and biochemical exams. Methods This is an experimental study with 12 albino rabbits as sample, which were divided into 3 groups and submitted to a hypercaloric diet for one month. Subsequently, subjects underwent UCV treatment: 3 minutes, 30 W, continuous mode at 100%, every 2 ERAS = 441.02 J/cm2, intensity of 10w/cm2. They were then euthanized and underwent biopsy after 24 hours. Results After 48 hours from the ultracavitation treatment, the animals' livers presented greater amount of fat infiltration if compared to the amount presented 96 hours after the treatment. However, laboratory tests showed no alterations. Values were maintained within normal parameters of cholesterol, triglycerides, liver enzymes, hemoglobin and hematocrit levels. Conclusions This study has identified that infiltrates may appear on livers after the treatment, despite high hematological and biochemical tests results. The fat infiltrates reduction 96 h after treatment suggests lower risks to animal health, if the period between applications is respected.

Introdução: O tratamento de pacientes portadores da síndrome da imunodeficiência adquirida deve ser integral e se basear no controle da doença e das complicações relacionadas ao uso de medicações antirretrovirais, como a lipodistrofia. Esse estudo tem como objetivo avaliar as principais queixas, os aspectos epidemiológicos e os procedimentos cirúrgicos realizados para corrigir a lipodistrofia em pacientes em uso crônico de antirretrovirais. Método: Estudo retrospectivo, no qual foram coletados dados dos prontuários de 27 pacientes submetidos a 36 procedimentos cirúrgicos relacionados à correção de lipodistrofia no período de março de 2010 a junho de 2014 no serviço de Cirurgia Plástica do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto. Resultados: A idade média dos pacientes foi 47,2 anos, 22,2% homens e 77,8% mulheres. O tempo médio de uso da terapia antirretroviral (TARV) foi de 12,1 anos. As queixas mais encontradas foram: giba dorsal (44,4%), lipodistrofia abdominal (44,4%) e lipoatrofia glútea (37,04%). Na maioria dos pacientes (70,4%), foi realizada uma cirurgia. Quanto às cirurgias, a lipoaspiração de giba foi realizada em 48,1% dos pacientes, seguida da lipoaspiração de abdome, dorso ou flancos (44,4%) e gluteoplastia (22,2%). Entre todos os 36 procedimentos realizados, apenas dois apresentaram complicações. O tempo médio de seguimento pós-operatório foi de 11,2 meses. Do total, 70,4% dos pacientes mostraram-se satisfeitos após os procedimentos. Conclusões: O sucesso do tratamento cirúrgico da lipodistrofia causada pelo uso da TARV baseia-se na seleção pré-operatória adequada e em seguimento constante e prolongado. A melhoria da autoestima facilita a adesão ao tratamento com antirretrovirais.
Introduction: Treatment of patients with acquired immunodeficiency syndrome should be complete and based on controlling the disease and the complications related to the use of antiretroviral medications, such as lipodystrophy. This study aimed to evaluate the main complaints, epidemiological aspects, and surgical procedures performed for lipodystrophy correction among patients receiving long-term antiretroviral therapy. Method: In this retrospective study, data were collected from the medical records of 27 patients who underwent 36 surgical procedures associated with lipodystrophy correction, from March 2010 to June 2014, at the Plastic Surgery Service of the Hospital das Clínicas, Faculty of Medicine of Ribeirão Preto. Results: The average age of the patients was 47.2 years; 22.2% were men and 77.8% were women. The average duration of antiretroviral therapy (HAAR ) was 12.1 years. The most frequent complaints were dorsal hump (44.4%), abdominal lipodystrophy (44.4%), and gluteal lipoatrophy (37.04%). The majority of patients (70.4%) had undergone surgery . The most common type of surgery performed was hump liposuction (carried out in 48.1% of the patients), followed by abdominal, back, or flank liposuction (44.4%) and gluteoplasty (22.2%). Among all 36 procedures performed, only 2 resulted in complications. The average postoperative follow-up period was 11.2 months. In total, 70.4% of patients were satisfied with the results of their procedure. Conclusions: The success of surgical treatment of HAARinduced lipodystrophy is based on proper preoperative selection as well as constant and prolonged follow-up. Improved selfesteem facilitates the adherence to antiretroviral drug treatment.

BACKGROUND: The gynoidlypodystrophy, known as cellulitis or cellulite, refers to a condition that gives the skin an undulating and uneven appearance, affecting 80-90% of women after puberty. OBJECTIVES: to investigate the efficacy and safety of manual lymphatic drainage for cellulite management. METHODS: this was an open, prospective, intervention study including 20 women aged from 20 to 40 years. Fourteen sessions of manual lymphatic drainage were performed once a week on lower limbs and buttocks. RESULTS: Fifteen women completed the study. A significant improvement on quality of life was observed (p=0.018). A significant reduction (p=0.023), estimated at 0.3±0.8 cm, in hip circumference was found, but no difference was found in thighs circumference (p>0.05). A significant reduction elastic recuperation of skin on buttocks, which means skin elasticity worsening, was observed. All measures obtained by ultrasound images showed no changes (p>0.05). CONCLUSION: manual lymphatic drainage was safe but not effective as an isolated approach for cellulite management. Further randomized, controlled or comparative studies about manual lymphatic drainage for cellulite control, as unique or combined therapeutic modality, are necessary. .

INTRODUCTION: Kobberling-Dunnigan syndrome is characterized by a series of alterations in metabolism and body fat distribution. Body dysmorphism and the Cushingoid appearance may have negative social and psychological impacts on the patient, including difficulty with social adaptation. In such cases, liposuction is used with the aim of improving body contour, with consequent improvements in self-esteem. The results are long lasting when body weight is maintained. CASE REPORT: Liposuction of the back, abdomen, and cervical regions in a woman with Kobberling-Dunnigan syndrome led to significant improvement in her body shape, and the results were maintained nine months postoperatively.
INTRODUÇÃO: A síndrome de Kobberling-Dunnigan caracteriza-se por um conjunto de alterações metabólicas e de distribuição da gordura corporal. O dismorfismo corporal e o aspecto cushingoide trazem repercussões psicológicas e sociais, com dificuldade de ajuste social. Nesses casos, a lipoaspiração é empregada com o objetivo de melhorar o contorno corporal e, consecutivamente, as alterações de autoestima. Os resultados apresentam-se duradouros quando há manutenção do peso. RELATO DO CASO: Paciente do sexo feminino, portadora de síndrome de Kobberling-Dunnigan, submetida a lipoaspiração de dorso, abdome e região cervical, com melhora significativa do contorno corporal e manutenção dos resultados nove meses após a operação.

A Síndrome de Madelung é um tipo raro de lipodistrofia descrita pela primeira vez em 1888 por Otto Madelung. Deste entäo, apenas 200 casos foram relatados na literatura. A condiçäo, de etiologia ainda desconhecida, caracteriza-se por uma deposiçäo de tecido adiposo simetricamente em: pescoço, ombros, regiöes supraclaviculares, suboccipital, tronco e regiäo proxima dos membros superiores, determinando um desfiguramento progressivo do doente. Embora usualmente assintomática, a doença pode causar complicaçöes severas, tais como: compressäo traqueal, laríngea ou mediastinal. O diagnóstico diferencial deve incluir outras lesöes do tecido celular cutâneo, a saber: lipomas, angiolipomas, neurofibromas, sarcomas, bem como outras lipomatoses. A excisäo cirúrgica é o único método efetivo de tratamento, sendo a operaçäo em geral trabalhosa devido à natureza hipervascularizada e fibrosa do tecido lipomatoso. Relata-se um caso de Síndrome de Madelung que está sendo acompanhado pelo serviço de Cirurgia Geral do HC-UFPR. O paciente, alvo de olhares curiosos pelo seu aspecto, vem sendo submetido a dermolipectomias e lipoaspiraçöes periódicas

El actual estudio trata sobre la forma de presentación y evolución de los pacientes con lipodistrofia congénita generalizada o el Síndrome de Seip-Berardinelli. Se caracteriza por la ausencia de tejido graso subcutáneo, cirrosis hepática, desarrollo de diabetes resistente a la insulina, hiperlipemia, y crecimiento corporal rápido con edad ósea avanzada en la infancia, coexistiendo alteraciones cutáneas, desarrollo muscular exagerado y compromiso de otros órganos. Se presentan 3 casos de esta patología diagnosticados entre 9 y 19 meses de edad. Las 3 pacientes presentaban varias características en común: aparentaban una edad mayor a la cronlógica, cara triangular, abundante cabello, lesiones hiperpigmentadas a predominio de pliegues, marcada disminución de tejido celular subcutáneo, prominencia muscular y hepatomegalia. Otros hallazgos clínicos sólo se demostraron en una u otra de las pacientes. La evaluación de laboratorio muestra alteración precoz de lípidos a predominio de triglicéridos, conservando la glicemia y la curva de tolerancia a la glucosa dentro de límites normales. Edad ósea avanzada en 1 de los 3 casos. Analizando los datos de las pacientes y de la literatura respecto a la fisiopatología y posibles efectos beneficiosos de los neurolépticos, se sugiere existencia de alguna anomalía a nivel del hipotálamo y/o hipófisis responsable de la presentacióm del cuadro clínico.

Se presenta el caso de un niño de 13 meses de edad con antecedentes de sepsis urinaria, anorexia severa y pérdida de peso desde los 4 meses de edad. Al examen físico se observa una facie simiesca con pérdida del panículo adiposo, hipertricosis generalizada, relieve muscular visible, ausencia del tejido celular subcutáneo, prominencia de la red venosa en miembros superiores e inferiores, manos y pies grandes, así como hipertrofia del pene. Se comprueba implantación baja de las orejas. Con estos elementos clínicos se sospecha que padezca de una lipodistrofia congénita generalizada, se le realiza biopsia muscular y se encuentra ausencia total de tejido adiposo, lo cual ayuda a confirmar el diagnóstico. Se detectan, también, alteraciones de los niveles lipídicos en sangre, no así en la glicemia. Se presenta este caso como una entidad de base genética, que se trasmite con carácter autosómico recesivo, pero de causa no totalmente esclarecida todavía. Se discuten algunos posibles mecanismos etiológicos así como terapéuticos. Consideramos que se debe profundizar más en estos aspectos para evitar complicaciones habituales, como la diabetes mellitus y los trastornos hepáticos
