Gluteoplasty using the Intramuscular (XYZ) Method

INTRODUCTION: The shape and size of the buttocks are essential to the notion of bodily beauty. This has resulted in a growing interest in gluteoplasty among both women and men. The aim of the present study was to present the author's experience with gluteoplasty using the intramuscular XYZ method. METHOD: Between 2010 and 2015, 29 patients aged 22 to 64 years (average, 43 years) underwent gluteoplasty; of these 26 were women (89.66%) and 3 were men (10.34%). Round or oval implants were used, with volumes of 240 to 420 ml (average, 330 ml), depending on the individual case. RESULTS: Good results were obtained in terms of volume increase and harmony of the gluteal region, with a high degree of patient satisfaction. CONCLUSIONS: The intramuscular XYZ method was safe, both for primary and secondary surgery, to treat cases of asymmetry and/or visible implants. Predetermining the XYZ reference points makes this procedure safe and reproducible

Increased osmotic sensitivity for antidiuretic response in chronic chagas' disease

O limiar de sensibilidade osmótíca para obtenção de resposta antídiurética foi avaliado em 31 pacientes com a forma crônica da moléstia de Chagas, através de infusão de salina hipertônica ou desidratação. Os resultados, quando comparados com os obtidos em 16 pacientes-controle, mostram uma sensibilidade osmótíca aumentada para os chagásicos, dados os menores valores do incremento na osmolaridade plasmática, suficiente para induzir uma queda significativa na depuração de água livre, sem alterações na depuração osmolar ou na excreção de creatínina. Também, o tempo necessário para atingir a antídiurese foi mais curto para os chagásicos do que para os controles. Os resultados sugerem a existência de um distúrbio na osmorregulação, nos pacientes chagásicos, caracterizado por uma sensibilidade osmótíca aumentada dos osmorreceptores para liberação da vasopressina. Estes dados interpretam-se como conseqüente à desnervação em áreas hipotalâmicas ou extra-hipotalâmicas, relacionadas com a secreção do hormônio antidiurético, na doença de Chagas.The osmotic threshold for attaining the antidiuretic response to hypertonic saline infusion and Progressive dehydration was studied in 31 patients with the chronic form of Chagas' disease and 16 control patients. The chagasic patients exhibited enhanced osmoticsensitivity to the antidiuretic response. This was demonstrated by lower values of the increments in plasma osmolarity sufficient to induce a significant fall in water clearance, without alterations in the osmolar clearance or creatinine excretion. The time needed to attain the antidiuretic response was shorterfor chagasics in relation to normal subjects. The results suggest the existence of a disturbance in the fine control of osmoregulation in the chagasic patients. They are interpreted to be a consequence of the denervation in hypothalamic or extrahypothalamic areas that regulate the secretion of vasopressin in chronic Chagas' disease

Quality of life and self-esteem in patients submitted to surgical treatment of skin carcinomas: long-term results

BACKGROUND:Cancer is a multifactorial disease and skin carcinomas are the most common type of cancer. Assessing quality of life and self-esteem outcomes in skin cancer patients is important because these are indicators of the results of the treatment, translating how patients face their lives and their personal relationships.OBJECTIVE:To assess the late impact of the surgical treatment of head and/or neck skin carcinomas on quality of life and self-esteem of the patients.METHODS:Fifty patients with head or neck skin carcinomas were enrolled. Their age ranged between 30 and 75 years, 27 were men and 23 were women. Patients were assessed with regard to quality of life and self-esteem, preoperatively and five years postoperatively. Validated instruments were used: the MOS 36-item Short-form Health Survey (SF-36) and the Rosenberg Self-esteem/EPM-UNIFESP Scale. The Wilcoxon signed-rank test was used for the statistical analysis.RESULTS:Twenty-two patients completed the five-year follow-up, 54.5% women and 45.5% men. Compared to the preoperative assessment, patients had an improvement in mental health (p=0.011) and in self-esteem (p=0.002). There was no statistical difference with regard to the other domains of the SF-36.CONCLUSION:Patients submitted to surgical treatment of skin carcinoma improved mental health and self-esteem in the late postsurgical testing.Universidade do Vale do SapucaíUniversidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

Dressing wear time after breast reconstruction: study protocol for a randomized controlled trial

Background: One of the major risk variables for surgical site infection is wound management. Understanding infection risk factors for breast operations is essential in order to develop infection-prevention strategies and improve surgical outcomes. the aim of this trial is to assess the influence of dressing wear time on surgical site infection rates and skin colonization. Patients' perception at self-assessment will also be analyzed.Methods/Design: This is a two-arm randomized controlled trial. Two hundred breast cancer patients undergoing immediate or delayed breast reconstruction will be prospectively enrolled. Patients will be randomly allocated to group I (dressing removed on postoperative day one) or group II (dressing removed on postoperative day six). Surgical site infections will be defined by standard criteria from the Centers for Disease Control and Prevention (CDC). Skin colonization will be assessed by culture of samples collected at predefined time points. Patients will score dressing wear time with regard to safety, comfort and convenience.Discussion: the evidence to support dressing standards for breast surgery wounds is empiric and scarce. CDC recommends protecting, with a sterile dressing for 24 to 48 hours postoperatively, a primarily closed incision, but there is no recommendation to cover this kind of incision beyond 48 hours, or on the appropriate time to shower or bathe with an uncovered incision. the results of the ongoing trial may support standard recommendations regarding dressing wear time after breast reconstruction.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de Minas Gerais (FAPEMIG)Universidade Federal de São Paulo, Dept Surg, Div Plast Surg, São Paulo, BrazilUniv Vale do Sapucai, Dept Surg, Div Plast Surg, Pouso Alegre, BrazilUniv Vale do Sapucai, Dept Microbiol, Pouso Alegre, BrazilUniv Vale do Sapucai, Sch Med, Pouso Alegre, BrazilUniv Vale do Sapucai, Dept Bioestat, Pouso Alegre, BrazilUniversidade Federal de São Paulo, Div Plast Surg, BR-04024002 São Paulo, BrazilUniversidade Federal de São Paulo, Dept Surg, Div Plast Surg, São Paulo, BrazilUniversidade Federal de São Paulo, Div Plast Surg, BR-04024002 São Paulo, BrazilCNPq: 480644/2011-0Web of Scienc

Mastectomia versus tratamento cirúrgico conservador: impacto na qualidade de vida de mulheres com câncer mamário

OBJECTIVES: to compare the impact of mastectomy and conservative surgery on the quality of life of patients with breast cancer. METHODS: an assessment was made of the quality of life of patients undergoing mastectomy or segmentary mastectomy, at the Pouso Alegre Clinical Hospital, in the Brazilian State of Minas Gerais, using SF-36. The patients were grouped by age (50 years) and years of schooling (8 years). The Mann-Whitney test was used to compare the groups with regard to the age and schooling domains of SF-36. RESULTS: a significant difference between the two groups was found in the domains of physical functioning (p=0.04) and pain (p=0.01): with the patients undergoing a mastectomy registering the worst scores. Young patients who had undergone a mastectomy displayed the worst quality of life in terms of physical functioning (p=0.03), pain (p=0.01) and social functioning (p=0.01); those undergoing conservative surgery aged over 50 years scored worst on role emotional (p=0.05). Patients undergoing a mastectomy with lower levels of schooling scored lower in physical functioning (p=0.01), role physical (p=0.05) and pain (p=0.05). Among those who had attended school for more than eight years, those having undergone a mastectomy scored less in the pain domain (p=0.04). CONCLUSIONS: patients who had undergone a mastectomy had worse results in the physical component of the evaluation of quality of life and this negative impact was more strongly felt among younger patients and those with lower levels of schooling.OBJETIVOS: comparar o impacto da mastectomia e da cirurgia conservadora na qualidade de vida de pacientes com câncer mamário. MÉTODOS: avaliou-se qualidade de vida de pacientes submetidas à mastectomia ou à mastectomia segmentar, no Hospital das Clínicas de Pouso Alegre, Minas Gerais, Brasil, utilizando-se o SF-36. As pacientes foram estratificadas quanto à idade (50 anos) e escolaridade (8 anos). Aplicou-se o teste de Mann-Whitney para comparar os grupos quanto aos domínios do SF-36, idade e escolaridade. RESULTADOS: observou-se diferença significante entre os grupos nos domínios capacidade funcional (p=0,04) e dor (p=0,01): as pacientes mastectomizadas com piores resultados. Pacientes mastectomizadas mais jovens apresentaram pior qualidade de vida em capacidade funcional (p=0,03), dor (p=0,01) e aspectos sociais (p=0,01); as submetidas à cirurgia conservadora, com mais de 50 anos, resultado pior em aspectos emocionais (p=0,05). Pacientes mastectomizadas com menor escolaridade apresentaram escores menores em capacidade funcional (p=0,01), aspectos físicos (p=0,05) e dor (p=0,05). Entre as que frequentaram a escola por mais de oito anos, as mastectomizadas pontuaram menos no domínio dor (p=0,04). CONCLUSÕES: pacientes mastectomizadas apresentaram piores resultados no componente físico da qualidade de vida, e este impacto negativo foi mais acentuado entre pacientes mais jovens e com menor escolaridade.Universidade do Vale do SapucaíUniversidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

Antibiotic prophylaxis in reduction mammaplasty: study protocol for a randomized controlled trial

Background: The role of antibiotics in surgical procedures where the risk of surgical site infection (SSI) is low remains uncertain. There is, to date, no evidence to justify the routine use of antibiotics in postoperative reduction mammaplasty. The aim of this study is to evaluate the effect of postoperative antibiotic treatment on the occurrence of SSI after breast reduction surgery. Methods: This is a double-blind randomized clinical trial with 124 breast hypertrophy patients allocated to two treatment groups: antibiotic (n = 62) and placebo (n = 62). All patients will undergo reduction mammoplasty, performed by the same surgical team. The surgeons will raise the nipple-areola complex by the superomedial pedicle technique. The patients will receive antibiotics intravenously during anesthetic induction and every 6 hours thereafter during their 24-hour hospital stay. During discharge from the hospital, each patient will receive a numbered package containing either cephalexin or placebo capsules and will be directed to take one capsule every 6 hours for 7 days. Neither the surgery team nor the patients will know the contents of the capsules. Patients will be monitored for the occurrence of SSI once weekly during the first 30 days following hospital discharge by a single surgeon who is blinded to their treatment group. SSI will be evaluated based on the definition adopted by the Centers for Disease Control and Prevention. Discussion: Due to the variety of risk factors for SSI and limited case studies, conclusions regarding the effect of antibiotics on the occurrence of SSIs following reduction mammaplasty are potentially biased. In recent studies, perioperative antibiotic prophylaxis was effective in preventing infection and is therefore recommended in clinical practice. However, antibiotic use in the postoperative period still remains controversial.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de Minas Gerais (FAPEMIG)Univ Fed Sao Paulo, Translat Surg Grad Program, Rua Napoleao Barros 725,4th Floor, BR-04024002 Sao Paulo, SP, BrazilUniv Vale Sapucai, Div Plast Surg, Ctr, Rua Comendador Jose Garcia 777, BR-37550000 Pouso Alegre, MG, BrazilTranslational Surgery Graduate Program, Universidade Federal de São Paulo (UNIFESP), Rua Napoleão de Barros, 725, 4th Floor, Vila Clementino, CEP: 04024-002 São Paulo, SP, BrazilCNPq: 444087/2014FAPEMIG: APQ-00995-15Web of Scienc

Abordagem oncoplástica no tratamento conservador do câncer mamário: análise de custos

PURPOSE: To analyze the direct costs of conservative surgical treatment of breast cancer, performed in a university hospital, to the Brazilian National Health Care Public System (SUS), checking the impact of the oncoplastic approach on these costs. METHODS: One hundred thirty eight breast cancer patients who had undergone conservative treatment with oncoplastic approach (n=36) or not (control group, n=102), in the period from 2005 to 2010, were enrolled. Sociodemographic and clinical data were recorded. The direct costs of the surgical procedure were obtained and analyzed. RESULTS: Groups did not differ in regard to age (p=0.963), and patients in oncoplastic group had a longer time of hospital stay (p=0.000). The median direct cost for the oncoplastic group was R$461.00 and for the control group was R$229.00 (p=0.000). CONCLUSION: The oncoplastic approach has generated higher direct costs in conservative surgical treatment of breast cancer to SUS.OBJETIVO: Analisar os custos diretos do tratamento cirúrgico conservador do câncer mamário, realizado pelo Sistema Único de Saúde (SUS) em um hospital universitário, verificando o impacto da abordagem oncoplástica sobre estes custos. MÉTODOS: Foram incluídas 138 pacientes submetidas ao tratamento conservador do câncer mamário pelo SUS, com abordagem oncoplástica (n=36) ou não (grupo controle, n=102), no período de 2005 a 2010. Foram registrados dados sócio-demográficos e da operação. Os custos diretos do procedimento cirúrgico foram obtidos e analisados. RESULTADOS: Não houve diferença entre os grupos quanto à idade (p=0.963), e o tempo de internação hospitalar foi maior no grupo oncoplástica (p=0,000). A mediana dos custos diretos do grupo oncoplástica foi de R$461,00 e do grupo controle foi de R$229,00 (p=0,000). CONCLUSÃO: A abordagem oncoplástica gerou custos diretos maiores para o tratamento cirúrgico conservador do câncer mamário pelo SUS.UNIVÁS Plastic Surgery DivisionUNIVÁS Mastology DivisionUNIVÁS Hospital das Clínicas Samuel Libânio Plastic Surgery DivisionUNIVÁS School of AdministrationUNIVÁS Bioestatistics DivisionUNIFESP Plastic Surgery DivisionUNIFESP Head of Plastic Surgery DivisionUNIFESP, Plastic Surgery DivisionUNIFESP, Head of Plastic Surgery DivisionSciEL
