Randomized Controlled Trial Clinical Trial
Bedtime dosing of glyburide and the treatment of type II diabetes mellitus.
Suppression of nocturnal hepatic glucose production is key in the treatment of noninsulin-dependent diabetes mellitus (NIDDM). In this article, the authors compare the effectiveness of dosing glyburide at bedtime versus in the morning on glycemic control in patients with NIDDM under suboptimal control. In a placebo-controlled, double-blind crossover trial, 32 patients with NIDDM with suboptimal control on chronic glyburide treatment fulfilling entry criteria were randomized to receive one of two regimens: (1) glyburide at bedtime and placebo in morning or (2) placebo at bedtime and glyburide in the morning. ⋯ At the end of 12 months, nighttime dosing resulted in better home glucose monitoring values, fasting blood sugar results, and Sustacal tolerance profiles, but the differences were not statistically significant. No hypoglycemia was observed in the monitored data collected. Bedtime dosing of glyburide resulted in measurable improvement in fasting blood sugar and carbohydrate tolerance curves, but not to a degree justifying general recommendation of this technique in patients with NIDDM with secondary failure to oral agents.

Case Reports
Case report: transverse colon volvulus in a patient with Clostridium difficile pseudomembranous colitis.
Sixty-eight cases of transverse colon volvulus have been reported in the literature. The authors report the first case of transverse colon volvulus in association with Clostridium difficile pseudomembranous colitis, with a review of the available literature. It is possible that the acute inflammation of the colonic mucosa, which occurred from the pseudomembranous colitis in this patient, contributed to the development of volvulus. Further studies are needed to explore the role of mucosal inflammation in the occurrence of volvulus.
