Controlled Clinical TrialEffect of long-term orlistat treatment on serum levels of advanced glycation end-products in women with polycystic ovary syndrome.
BACKGROUND Women with polycystic ovary syndrome (PCOS) exhibit elevated serum advanced glycation end-products (AGE) compared with healthy subjects. Short-term administration of orlistat has been shown to reduce the postmeal increase in serum AGE levels in women with PCOS and in controls. ⋯ Our data suggest that orlistat has a beneficial effect in reducing elevated AGE levels and improving the hormonal and metabolic profile in women with PCOS after 6 months of treatment, independently of BMI changes.

Combined clinical, thyroid ultrasound and cytological features help to predict thyroid malignancy in follicular and Hupsilonrthle cell thyroid lesions: results from a series of 505 consecutive patients.
The cytological patterns of follicular and Hupsilonrthle cell nodules are included among the indeterminate results of fine-needle aspiration cytology, because distinction between benign and malignant lesion can only be made on histological criteria. The diagnostic value of atypia at cytology, clinical parameters and echographic patterns were examined to establish the risk of malignancy in 505 patients with follicular and Hupsilonrthle cell thyroid nodules at cytology. ⋯ Twenty-five per cent of patients with a cytological result of follicular and Hupsilonrthle cell thyroid lesion had a final diagnosis of malignancy. Only atypia at cytology and spot microcalcifications at thyroid ultrasound were significantly associated with malignancy. Other clinical parameters and thyroid ultrasound patterns can be used to set up a clinical score useful for predicting the individual risk of malignancy before surgery.
