Hypercalciuria is a common and important finding in postmenopausal women with osteoporosis.

Objective And Design: The prevalence and the effects of hypercalciuria on bone in patients with primary osteoporosis are poorly defined. We therefore retrospectively analyzed the data of 241 otherwise healthy women. They were 45-88 years of age and had been referred for their first visit to our Unit for Metabolic Bone Diseases over a 2-year period because of primary osteoporosis (bone density T-score < -2.

Hyperparathyroidism: cause or consequence of recurrent calcium nephrolithiasis?

Primary hyperparathyroidism (PHP) might be characterized by either prevailing bone or renal stone patterns with different metabolic features. To explore the possibility of different hormonal patterns we studied 129 patients with PHP: 95 stone formers (SF) and 34 nonstone formers (NSF). Females prevailed over males in both groups.

Longitudinal study on osteodystrophy in primary biliary cirrhosis (PBC) and a pilot study on calcitonin treatment.

The aims of this study were to evaluate bone metabolism in primary biliary cirrhosis (PBC) and the effect of ADFR (activate, depress, free, repeat) therapy with vitamin D, calcium and calcitonin in preventing bone resorption. Sixty-nine female subjects entered the study: 38 PBC (AMA + ve) patients, 11 AMA-negative chronic liver disease patients and 20 age-matched healthy controls. Bone metabolism was evaluated by biochemical parameters and dual-photon absorptiometry of the lumbar spine at time 0, 6 and 18 months.

Efficacy of captopril in hypertensive diabetic patients.

Twenty hypertensive diabetic patients (10 with type I and 10 with type II) were treated with captopril, 50 mg twice a day, for three months. The drug was effective as monotherapy in 16 patients. An additional nine months of follow-up was obtained in 12 of these patients (four with type I and eight with type II) who did not need the addition of diuretics to achieve normal blood pressure.

Exogenous calcitonin protects against renal bone disease in rats with early renal failure.

Chronic renal failure was induced in four groups of male Sprague-Dawley rats by unilateral nephrectomy followed by removal of the outer poles and cautery of the remnant kidney. The four groups of animals received isocaloric diets with normal (groups 1 and 4) or low (groups 2 and 3) phosphate contents and variable amounts of calcium. In addition, rats in group 4 were given salmon calcitonin.
