Intermaxillary fixation as co-adjuvant treatment for morbid obesity

Background: the effective long-term treatments for morbid obesity is bariatric surgery. However, the associated surgical and anesthetic risks led the authors to evaluate intermaxillary fixation, a less aggressive procedure, as a preoperative treatment in selected patients with morid obesity.Methods: 22 patients (5 male, 17 female, ages 16-53 years, with BMI 44.9 +/- 5.4 kg/m(2)) underwent intermaxillary fixation. The procedure consisted of fitting brackets on the front face of the teeth and posterior application of elastic bands to impede mouth opening.Results: At the end of 6 weeks, weight loss was 7.4 +/- 2.6% there was general improvement in lipid profile, glycemia, and blood pressure. There was no recorded discomfort, pain, or any other difficulty during this treatment.Conclusion: Intermaxillary fixation can be used as a pre-surgical solution for weight reduction in preparation for bariatric surgery, improving co-morbid aspects such as blood pressure, glycemia, and lipid profile.

Menstrual irregularity: a possible clinical marker of metabolic dysfunction in women with class III obesity

Purpose. To evaluate whether menstrual irregularity in morbidly obese women is indicative of metabolic dysfunction.Patients and Methods. Fifty-seven women with morbid obesity were evaluated. They were divided into two groups: one comprising women without menstrual dysfunctions or hirsutism (Group 1), and another obese women showing menstrual dysfunction with or without hirsutism (Group 2). The following were evaluated: age, colour, childbirth, marital status, profession, socio-economic level, education, age at menarche, body weight, height, body mass index, presence of hirsutism (Ferriman Gallwey Index), abdominal circumference, hip circumference, waist-to-hip ratio, menstrual cycle, blood pressure, presence of acanthosis nigricans, insulin resistance (IR), fasting glycaemia, total cholesterol, HDL-C, LDL-C, triglycerides, thyroid-stimulating hormone, free T4, luteinising hormone (LH), follicle-stimulating hormone, prolactin, total testosterone, dehydroepiandrosterone sulfate, insulin and the Homeostasis Model Assessment (HOMA test).Results. Clinical and epidemiological aspects did not present statistical differences. Clinical and laboratory parameters did not show statistically significant alterations; however, HOMA test values for Group 2 were significantly higher than those for Group 1.Conclusions. The presence of IR in class III obese women can cause menstrual dysfunctions such as amenorrhoea or oligomenorrhoea even in the absence of hyperandrogenism, suggesting that IR plays an important role in the ovarian mechanisms involved in the menstrual cycle control.

Decrease in circulating glucose, insulin and leptin levels and improvement in insulin resistance at 1 and 3 months after gastric bypass

Background: Hyperglycemia, insulin resistance and hyperleptinemia are some of the consequences of obesity. Gastric bypass for morbid obesity provides gastric restriction with decreased energy absorption. To confirm and extend previous reports in the literature, We evaluated the plasma glucose, serum insulin and leptin and insulin resistance of patients preoperatively and 1 and 3 months after Roux-en-Y gastric bypass (RYGBP).Methods: We determined body mass index (BMI), plasma glucose (glucose-oxidase method), serum leptin (immunoassay) and insulin (chemiluminescent immunometric assay), and insulin resistance index (IRI) by Homeostasis Model Assessment (HOMA) of 20 patients with morbid obesity both preoperatively and 1 and 3 months after RYGBP.Results: Patients showed a mean decrease in weight of 8 kg/month. Glycemia was above reference levels in 65% of the preoperative patients but dropped significantly 1 month postoperatively, serum insulin and leptin levels and the HOMA index also decreasing significantly in the same period. The percentage of patients with preoperative elevated serum insulin and leptin relative to reference levels decreased significantly following RYGBP. We also observed a weak but significant correlation between BMI and glucose, BMI and insulin, and leptin and insulin.Conclusions: the beneficial effects of bariatric surgery are already noticeable 1 month postoperatively, the reduction in insulin levels being more important for leptin reduction than decreased BMI. Leptin appeared to be subject to multifactorial control and showed a larger reduction than body weight.

Evolução e classificação do peso corporal em relação aos resultados da cirurgia bariátrica: derivação gástrica em Y de Roux

OBJETIVO: Avaliar a evolução e a classificação do peso corporal em relação aos resultados da cirurgia bariátrica em mulheres submetidas ao procedimento cirúrgico há mais de dois anos. SUJEITOS E MÉTODO: Foram avaliadas 141 mulheres submetidas à derivação gástrica em Y de Roux (DGYR) com anel de contenção. As participantes foram divididas de acordo com o tempo de pós-operatório e conforme o percentual da perda do excesso de peso (%PEP): < 50; 50 ┤ 75; e, > 75. RESULTADOS: As mulheres do grupo com %PEP < 50 (15,6%) se mantiveram obesas, enquanto aquelas que apresentaram %PEP > 75 (36,2%) situaram-se entre a eutrofia e préobesidade e tiveram menor índice de recuperação tardia de peso em relação aos demais grupos. CONCLUSÃO: A evolução de peso após dois ou mais anos da cirurgia mostrou sua esperada redução com variados graus de resposta, apontando a necessidade de monitoramento, investigação e intervenção para obtenção dos resultados esperados.
