The effect of antiresorptive therapy with nasal calcitonin (CT) in recently diagnosed hyperthyroid patients on conventional medical therapy as well as the evolution of bone metabolism were assessed. Forty-five patients with recent-onset hyperthyroidism (<12 weeks) were sex and menopause stratified and randomly allocated to treatment with carbimazole(More)
In this study the location of the lower oesophageal sphincter measured by manometry and the location of the squamous columnar junction measured by endoscopy were determined in 109 healthy controls and 778 patients with different degrees of endoscopic oesophagitis. No significant differences in the prevalence and severity of the heartburn and regurgitation(More)
Swine exposed to cold air have elevated serum values of total triiodothyronine (TT3) and free T3 (FT3). To characterize the mechanism of these increases, we measured in vivo kinetic parameters after a bolus intravenous injection of 125I-labeled T3 by use of both multicompartmental (MC) and noncompartmental (NC) methods and in vitro hepatic type I(More)
BACKGROUND/AIMS This prospective study evaluates the peristaltic activity of the thoracic esophagus in a group of patients with gastroesophageal reflux disease grouping them according to the endoscopic findings. MATERIALS AND METHODS The peristaltic activity and the manometric features of the lower esophageal sphincter were prospectively evaluated in 109(More)
Although the negative effect of systemic steroids on bone is well documented, there is not clear evidence about possible adverse effects of inhaled steroids on bone metabolism and fractures. A cross-sectional study was performed on 105 women suffering from bronchial asthma treated with inhaled steroids and 133 controls. Bone mineral density (BMD) was(More)
The subepithelial lesions of the gastrointestinal tract are related to mesenchymal tumors and 80% of them are GIST (gastrointestinal stromal tumors). However, there are also other tumors, such as: leiomyomas, schwannomas, lipomas, glomus tumors, carcinoid tumors, aberrant pancreas and polyps or inflammatory tumors. Diagnosis of submucosal tumors is often(More)
