Ultrasound guided percutaneous ethanol injection in the treatment of cystic thyroid nodules.

Objective: The management of cystic lesions in the thyroid remains controversial. We examined the efficacy and safety of ultrasound guided percutaneous ethanol injection for the treatment of benign cystic thyroid nodules in euthyroid patients.

Study Design: (A) Preliminary randomized trial: 20 patients with predominantly cystic thyroid nodules were randomized in two groups and followed up for 1 month.

Bone loss in prednisone treated sarcoidosis: a two-year follow-up.

We followed up 35 sarcoid patients treated with prednisone for two years in order to evaluate bone mineral loss over time. Vertebral cancellous mineral content was detected by quantitative computed tomography and calibration phantom before beginning prednisone therapy and monitored two more times at yearly intervals. The percent mineral loss (ML%) averaged -13.
