Background: Polycystic ovary syndrome (PCOS) is an endocrine metabolic dysfunction closely associated with insulin resistance and obesity, which predisposes to pregnancy complications., Aim: To report a prospective clinical experience in PCOS patients who became pregnant after diet, exercise and metformin treatment intervention, and were followed up during the whole pregnancy., Patients and Methods: Seventy pregnant PCOS (PPCOS) women and forty normal pregnant (NP) women of similar age and with singleton pregnancies were included in the study. During gestational ages 10-16 and 22-28 weeks, a 2h, 75 g oral glucose tolerance test (OGTT) was performed with measurement of glucose and insulin in each sample., Results: No differences were found in duration of gestation, weight gain during pregnancy, or systolic and diastolic blood pressure between PPCOS and NP women. There were significant differences in body mass index (BMI) at the initiation and in the third trimester of pregnancy between both groups. The incidence of gestational diabetes was significantly higher (p <0.01) in the PCOS group (35.2%) compared to the control group (5.0%). The prevalence of small for gestational age (SGA) infants tended to be higher (p =0.09) in the PCOS group. During pregnancy, 2h glucose and insulin were significantly higher in PPCOS than in NP women., Conclusions: PCOS mothers showed a higher prevalence of gestational diabetes and SGA newborns, which cannot be attributed to the weight gain during pregnancy, and seems to be more related to the BMI at the initiation of pregnancy, and to the PCOS condition of the mother.

Polycystic ovary syndrome (PCOS) is a very common disorder that occurs up to 10% of premenopausal women. Although PCOS is known to be associated with a higher reproductive morbility and increased risk of hormone dependent-cancer, its diagnosis is particularly important because PCOS is strongly linked to insulin resistance. This involves a major risk of early metabolic and cardiovascular complications. On the other hand, the prevalence of metabolic disorders associated with insulin resistance is higher in family members of patients with PCOS than in those of normal women, which suggests that the treatment of this syndrome should be preventive rather than symptomatic. For that reason, PCOS might be considered a signal of a family disorder, a route to diabetes and a public health problem.

Risk of perforation is a major impediment to the use of polyvinyl bougies in palliative dilation of cancerous strictures of the esophagus. We encountered 23 patients with complex malignant strictures in whom initial dilation with Savary-Gilliard bougies was thwarted because attempts to pass a conventional Eder-Puestow guide wire were unsuccessful. As a recourse, we probed these strictures with a very flexible guide wire of the type used to implant prostheses in the biliary tract. The purpose was to establish a passage through which a standard guide wire could then be inserted. The procedure was successful in all but 4 of the 23 patients. We conclude that in such cases the preliminary use of the very flexible guide, even though time-consuming, improves the chance of effective dilation with minimal added risk.
