Specific haplotypes of the CALPAIN-5 gene are associated with polycystic ovary syndrome.

Background: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. The aim of the present study was to investigate the role of CALPAIN-5 (CAPN5) gene in PCOS susceptibility.

Methods: We analysed four intronic polymorphisms of the CAPN5 gene in 148 well-characterized women with PCOS and 606 unrelated controls.

In vivo visualization of pituitary dopaminergic receptors by iodine-123 methoxybenzamide (IBZM) correlates with sensitivity to dopamine agonists in two patients with macroprolactinomas.

We performed in two patients with macroprolactinoma, pituitary scintigraphy with 123 iodine-methoxybenzamide (IBZM), a dopaminergic antagonist that specifically binds to the D2 dopaminergic receptors. In a 34-yr-old woman with basal PRL levels of about 2000 ng/mL, 7.5 mg/day of Bromocriptine (Br) for a month neither reduced PRL levels nor affected tumor size; in this patient single photon emission tomography SPECT failed to show any pituitary accumulation of the tracer.

Scintigraphic oesophageal clearance in diabetics: clinical usefulness.

The whole digestive tract is one of the sites most involved in diabetic autonomic neuropathy. The aim of this work was to validate the clinical usefulness of oesophageal scintigraphy in the early detection of this complication of diabetes. Eighty-one diabetic patients without oesophageal symptoms were studied by solid meal scintigraphic test (SMST) and 35 out of them also by liquid meal scintigraphic test (LMST).
