Postprandial hypoglycemia is a common complication of bariatric surgery. It is usually caused by late dumping syndrome, but a few other causes have already been described, including insulinoma and noninsulinoma pancreatogenous hypoglycemic syndrome (NIPHS). Considering that NIPHS is a recently described syndrome and is also very rare, therapeutic approaches are still not consensual. We report the case of a 26-year-old woman who was submitted to bariatric surgery and presented episodic postprandial hypoglycemic episodes after 16 months. Fasting C-peptide, insulin, and glucose were normal. Because of the possibility of NIPHS, clinical treatment was initiated with verapamil and acarbose, leading to a significant reduction of hypoglycemic episodes and also their severity. Surgery is the most common approach to NIPHS. However, in cases of mild or moderate symptoms, it is important to consider the possibility of pharmacological treatment. This approach may result, at least for some time, in an amelioration of symptoms without the need of an aggressive procedure.

Adolescent obesity is becoming a health problem in both developed and developing countries. Antiobesity drug therapy is not currently indicated for the treatment of adolescent obesity and remains investigational at this time. The aim of this study was to determine the efficacy and safety of sibutramine in obese adolescents. A randomized, double-blind, placebo-controlled trial, enrolling 60 adolescents, aged 14-17 yr, for 6 months was conducted. In the first month, all patients received placebo and a hypocaloric diet plus exercise orientation. For the next 6 months, participants received either sibutramine or placebo. Patients assigned to sibutramine group lost an average of 10.3 +/- 6.6 kg, and patients in placebo group lost 2.4 +/- 2.5 kg (P < 0.001). The mean body mass index reduction was significantly greater in the sibutramine group (3.6 +/- 2.5 kg/m(2)) than in the placebo group (0.9 +/- 0.9 kg/m(2); P < 0.001). No participant withdrew because of adverse events, and no difference in blood pressure or heart rate was noted between groups. There were no changes in echocardiographic parameters. In conclusion, sibutramine plus diet and exercise induced significantly more weight loss in obese adolescents.

BackgroundComorbid depression in diabetes has been suggested as one of the possible causes of an inadequate glycemic control. The purpose of this study was to investigate the association between major depression and the glycemic control of type 2 diabetes mellitus (T2DM).MethodsSeventy T2DM patients were evaluated. They underwent a psychiatric examination using the following instruments: Structured Clinical Interview for DSM-IV and Beck Depression Inventory. The diabetes status was assessed in the short-term (glycemia, glycated hemoglobin) clinical control.ResultsThe presence of current depression was observed in 18.6% (13/70). In addition, type 2 diabetes patients who displayed depression evidenced higher levels of glycated hemoglobin (8.6 ± 2.0 vs. 7.5 ± 1.8; p = 0.05) when compared to those who did not exhibit a mood disorder.ConclusionsIn our sample, the presence of depression seems to impact on the short-term control of T2DM. The authors discuss the clinical utility of these findings in the usual treatment of diabetes.
