To examine the performance of weight-based formulae for estimating the levothyroxine dosage requirement in athyreotic patients and to determine whether formula performance is affected by age, sex, or menstrual status. ⋯ When actual body weight was used to calculate levothyroxine dosage requirement, premenopausal women appeared to have a greater requirement than either menopausal women or men. When ideal weight was used, the requirement of all women was greater than that of men. Perhaps with formulae using actual weight, this apparent sex difference is masked by the greater weight, older age, or altered hormonal milieu of menopausal women.

Safety and efficacy of an insulin infusion protocol designed for the non-intensive care setting.
To determine whether glycemic control can be safely achieved with use of a simplified insulin infusion protocol in hospitalized patients who are not in the intensive care unit (ICU). ⋯ Use of a simple intravenous insulin protocol can safely and effectively control the blood glucose level in patients in a non-ICU setting.

To describe a case of recurrent takotsubo cardiomyopathy in a patient with pheochromocytoma. ⋯ In patients presenting with takotsubo cardiomyopathy, a precipitating factor, such as emotional or physical stress, can often be identified. In some patients (such as our current case), however, pheochromocytoma may be the underlying disease and should be considered.

To determine the implications of the presence of hyperglycemia after a cardiac surgical procedure in patients with no history of diabetes mellitus (DM). ⋯ Hyperglycemia after a cardiac surgical procedure implies a high risk of persistent glucose dysregulation. Preoperative FPG levels correlated better with 2-hour OGTT results than did the 6-week postoperative FPG values, but both were insensitive markers for diagnosing type 2 DM in these patients. In our cohort, hemoglobin A1c was not predictive of abnormalities of glucose metabolism. Our data support the need for performing a postoperative OGTT in patients with no known history of DM but the presence of hyperglycemia after a cardiac operation.
