The ankle--brachial index and the diabetic foot: a troublesome marriage.

Background: The ankle--brachial index (ABI) is a simple, noninvasive, widely used test that detects peripheral arterial disease (PAD). In patients with diabetes, the ABI is notoriously unreliable and this is usually attributed to medial calcinosis, which stiffens the arteries and renders them poorly compressible. However, the distribution of atherosclerotic lesions in those with diabetes is different as well: lesions predominantly reside in below-the-knee (BTK) arteries.

Outpatient gastroplasty for morbid obesity: our first hundred cases.

Background: Laparoscopic adjustable gastric banding (LAGB) is a safe and effective treatment for morbid obesity. The aim of the present study was to identify factors actually contributing to the feasibility or to the failure of performing this procedure in an outpatient setting.

Methods: In this prospective study, 100 ambulatory LAGB procedures were compared with 100 procedures performed in patients with an overnight stay.

A case of thyroid hormone resistance: Prospective follow-up during pregnancy and obstetric outcome.

We describe the case of a patient with resistance to thyroid hormone (R243W substitution) and her obstetric outcome. The patient gave birth to a healthy girl, unaffected by the R243W mutation. Two years later, following an uneventful pregnancy, a baby boy was born at term; he presented the same thyroid hormone receptor mutation as his mother.
