Reversible Kallmann syndrome (KS) is a rare variant of hypogonadotropic hypogonadism (HH) reported in men, in which gonadotropin, testosterone (T) and fertility recover spontaneously following treatment with gonadotropins or T. In a few cases mutations of FGFR1 and KAL1 genes have been found. In this report we describe a subject with a KS carrying a new homozygous mutation of PROK-R2 gene and displaying an apparent reversal of his reproductive condition. The proband, born from...

Background: Adrenal masses can be detected by ultrasound with high sensitivity and specificity. However, a differentiation between benign and malignant adrenal masses is presently not possible. Contrast-enhanced ultrasound has been studied intensively with excellent results for the characterization of liver lesions.The aim of the present study was to evaluate the value of contrast-enhanced ultrasound for the characterization of adrenal mass in a proof of...

Subject: Adrenal tumours (AT) are often detected incidentally and represent a variety of differential diagnoses with variable therapeutic consequences. We have recently developed [123I]Iodometomidate ([123I]IMTO), that specifically binds to adrenal CYP11B enzymes as a SPECT tracer for adrenal scintigraphy. This radiotracer is now evaluated in patients with adrenal tumours in an ongoing clinical trial. The study was approved by the ethical committee and pa...

The aim of this study is to evaluate endothelial function in patients with primary hyperparathyroidism (pHT) during the preoperative hypercalcemic and postoperative normocalcemic periods and to determine whether intron 4a/b polymorphism of eNOS gene influences endothelial function. Forty-one patients with pHT (28 women, 12 men; age: 48.4±11.6 years, serum calcium: 11.4±1.0 mg/dl, parathyroid hormone: 373.3±394.5 pg/ml) who fulfilled the criteria for parathyroid ...

Background: Cabergoline, a dopamine receptor-2 agonist, used to treat prolactinomas was associated with increased risk of cardiac valve disease.Objective: To evaluate prevalence of cardiac valve regurgitation in patients with prolactinomas treated with cabergoline.Design: Open, case–control, prospective.Patients: Fifty patients (44 women, 6 men) and 50 sex- and age-matched control subjects.<p class="...

Background: PPARγ-agonist treatment may decrease bone mineral density (BMD) in postmenopausal women. The hypothesis that premenopausal women are relatively protected from mineral loss during PPARγ-agonist treatment has not been evaluated in clinical studies.Aim: To investigate the effect of pioglitazone on BMD and bone turnover markers in patients with polycystic ovary syndrome (PCOS).Methods: Thirty premenopausal PCOS pa...
