The Optimal Parathyroid Hormone Cut-Off Threshold for Early and Safe Management of Hypocalcemia After Total Thyroidectomy.

Objective: To define optimal intact parathyroid hormone (iPTH) cut-off threshold predictive of hypocalcemia after total thyroidectomy for safe and effective postoperative management.

Methods: This prospective single center study was done in 2 phases. In phase I, predictors of symptomatic hypocalcemia were analyzed and the receiver operating characteristic curve was used to define the optimal iPTH cut-off threshold predictive of hypocalcemia.

Factors influencing dyslipidemia in statin-treated patients in Lebanon and Jordan: results of the Dyslipidemia International Study.

Background: Cardiovascular disease is the leading cause of death and disability worldwide. Therefore, as part of the Dyslipidemia International Study (DYSIS), we have analyzed the prevalence of lipid abnormalities and risk factors for dyslipidemia in statin-treated patients in Lebanon and Jordan.

Methods: This cross-sectional, multicenter study enrolled 617 patients at 13 hospitals in Lebanon and Jordan.

Sleepwalking associated with hyperthyroidism.

Objective: To report several cases of hyperthyroidism in patients presenting with the unusual symptom of sleepwalking and to discuss the possible pathophysiologic basis for this novel association.

Methods: After encountering and reporting the first case of new-onset somnambulism in a patient presenting with thyrotoxicosis at our institution, we routinely inquired about the sleep history of patients with thyrotoxicosis, questioning both the patients and family members when applicable. Those patients who actually had sleepwalking episodes coinciding with the onset of thyrotoxicosis underwent close follow-up, and the relationship between the sleepwalking and the results of thyroid function tests was analyzed.
