Impact of inflammatory bowel disease on women's reproductive life: a questionnaire-based study.

Background: Inflammatory bowel diseases (IBDs) have a peak incidence between the second and fourth decades of life and can affect women's reproductive life.

Objectives: Our study aimed to assess the impact of IBD on the reproductive life of female patients with this condition.

Design: Cross-sectional study.

A novel T608R missense mutation in insulin receptor substrate-1 identified in a subject with type 2 diabetes impairs metabolic insulin signaling.

Naturally occurring mutations in insulin receptor substrate-1 (IRS-1) have previously been implicated in impaired insulin action. We now report a novel mutation in IRS-1 with substitution of Arg for Thr(608) that was identified in a patient with type 2 diabetes mellitus. We detected the T608R mutation in 1 of 136 chromosomes from diabetic patients and in 0 of 120 chromosomes from nondiabetic controls, suggesting that this is a rare IRS-1 variant.

Interaction between the G1057D variant of IRS-2 and overweight in the pathogenesis of type 2 diabetes.

The insulin receptor substrate-2 (IRS-2) is a major insulin signalling molecule. IRS-2 inactivation in mice induces a form of diabetes characterized by peripheral insulin resistance and reduced beta cell mass. We tested the hypothesis that a common non-conservative amino acid substitution of IRS-2 (G1057D) might interact with overweight in the pathogenesis of type 2 diabetes.

Does holiday hypoglycaemia exist?

Background: To determine whether an excessive, prolonged and, above all, unusual physical exertion could be associated with episodes of mild hypoglycaemia in non-insulin-dependent diabetes mellitus (NIDDM) patients treated with glibenclamide.

Experimental Design: 11 months of observation with retrospective analysis of patient personal diaries to determine the hypoglycaemic risk.

Setting: Diabetic Unit-Department of Medicine and Aging-Chieti University School of Medicine.
