Tophaceous gout in a young man with Gitelman syndrome: a case report with an overview.

Gitelman syndrome represents the clinical manifestations of inactivation of the Slc12a3 genes encoding the thiazide-sensitive sodium chloride cotransporter and the Trpm6-Mg genes encoding the magnesium transporters in the distal convoluted tubule. In fact, the biochemical findings resemble those with thiazide diuretics such as hypokalemia, hypomagnesaemia, hypocalciuria, metabolic alkalosis, and low normal blood pressure. He is usually associated with calcium pyrophosphate deposition.

Percutaneous biopsy of osteoid osteomas prior to percutaneous treatment using two different biopsy needles.

Biopsy is usually performed as the first step in percutaneous treatment of osteoid osteomas prior to laser photocoagulation. At our institution, 117 patients with a presumed diagnosis of osteoid osteoma had a trephine biopsy before a percutaneous laser photocoagulation. Biopsies were made using two different types of needles.

[CT evaluation of locoregional spread of carcinoma of the gallbladder].

Objective: This study aims to assess the diagnostic capability of CT to preoperatively detect evidence of locoregional spread of gallbladder cancer.

Patients And Methods: Two radiologists independently performed retrospective review of CT scans on 20 patients who had undergone surgical resection for carcinoma of the gallbladder. Local spread was categorized by the TNM system and the results were correlated with surgical and pathologic findings.
