Clinical, metabolic, and endocrine parameters in response to metformin and lifestyle intervention in women with polycystic ovary syndrome: a randomized, double-blind, and placebo control trial.

The aim of this study was to evaluate the effects of metformin in addition to diet and exercise on endocrine and metabolic disturbances in women with polycystic ovary syndrome (PCOS) in a prospective, double-blind, randomized, placebo (PBO) control trial. Thirty women with insulin resistance and PCOS received lifestyle modification and 1500 mg of metformin or placebo for 4 months. Before and after treatment, body mass index, waist/hip ratio, blood pressure, hirsutism, and menstrual patterns were evaluated.

[Thyroid carcinoma. A descriptive retrospective study].

Unlabelled: The thyroid carcinoma (TC) is not very frequent among all cancers. Its course is slow and is high potentially curable. Our aim was to analyse the characteristics in patients with TC.

Hospital discharge of patients with thyroid carcinoma treated with 131I.

Unlabelled: A dose limit-based criterion was proposed to authorize hospital discharge of thyroid carcinoma patients treated with 131I. Evaluation of accumulated doses to determine the effective half-life, the expected accumulated dose at 1 m, and the hospitalization time was performed to ensure that the dose limit was satisfied for each patient. Situations involving different dose limits and occupancy factors were analyzed.
