[Evaluation of bone health in transgender people. Position of the Argentine Osteoporosis Society].

The Argentine Osteoporosis Society convened renowned specialists in the care of transgender people to prepare the first local position on the evaluation of bone health in this population. Law 26.743 on "Gender Identity" recognize all identities and guarantees free care throughout the health system.

[High frequency of thyroid abnormalities in polycystic ovary syndrome].

The prevalence of thyroid abnormalities (TA) has not been sufficiently assessed in polycystic ovary syndrome (PCOS). Our aim was to evaluate this relationship. In this prospective study 194 women were included.

[Critical evaluation of the oral glucose tolerance test for the diagnosis of insulin resistance in patients with polycystic ovary syndrome].

Oral glucose tolerance test (OGTT) is the most commonly used method to evaluate insulin resistance (IR) in the clinical practice. Our objective was to evaluate the diagnostic utility of fasting tests compared with OGTT tests in women with PCO, and the ability of fasting tests to detect postprandial hyperglycemia. One hundred fourteen women with PCO and 29 normal women were evaluated by a 2 hours OGTT.

[Incomplete Carney's Triad and arterial hypertension in a young woman].

The case of young woman with arterial hypertension diagnosed two years before, is here presented; she had a ferropenic anemia caused by digestive loss of blood. Multiple gastric tumors and pararenal non functioning paraganglioma were found. No chondromas were detected.

[Leptin in patients with polycystic ovary syndrome. Direct correlation with insulin resistance].

Up to now it is unclear whether there is a relationship between insulin resistance and circulating leptin levels (LEP) in women with polycystic ovary syndrome (PCOS). To assess the role of LEP in PCOS and to clarify the relationship between plasma LEP levels and insulin resistance (IR) in PCOS patients, we studied 49 women with PCOS and 14 normal premenopausal women. All subjects were evaluated by a 2 hours, 75 g, oral glucose tolerance test.

Insulin sensitivity in young women with vasovagal syncope.

Background: Insulin, in addition to its known metabolic effects, has sympatho-excitatory and vasodilatory actions on muscular blood vessels. The goal of this study was to evaluate insulin sensitivity in young women with vasovagal syncope and positive tilt test results (HUT+) and to compare it with that in patients with negative tilt test results (HUT-) and in control subjects without a history of syncope.

Methods: Different indices of insulin sensitivity were obtained by an oral glucose tolerance test (OGTT) in 13 young women with syncope and HUT+ (age 26.
