Preoperative ultrasonography parathyroid gland mapping can improve identification of normal parathyroid gland during thyroidectomy: A propensity score-matched case-control study.

Background: Accurate intraoperative identification of normal parathyroid glands (PTGs) is vital to avoid hypocalcemia post total thyroidectomy. Although ultrasonography (US) has been shown to identify normal PTGs, the significance of preoperative US PTG mapping in this context is not well studied. This study evaluated the impact of preoperative US PTG mapping on intraoperative identification of normal PTGs during total thyroidectomy.

Similarities and Differences Between Thyroid Imaging Reporting and Data Systems.

The purposes of this study were to identify the similarities and differences among the Korean Thyroid Imaging Reporting and Data System (TIRADS), American College of Radiology (ACR) TI-RADS, and European TIRADS and to compare the diagnostic performance of sonographic fine-needle aspiration (FNA) criteria for detecting malignant thyroid nodules. This study included 2274 consecutively evaluated thyroid nodules 1 cm or larger in 1836 patients with final diagnoses from January 2011 to December 2016. US features of the nodules were retrospectively reviewed and classified according to three published guidelines from international societies.

Effects of spironolactone and losartan on diabetic nephropathy in a type 2 diabetic rat model.

Background: While there is an evidence that the anti-inflammatory properties of spironolactone can attenuate proteinuria in type 2 diabetes, its effects on vascular endothelial growth factor (VEGF) expression in diabetic nephropathy have not been clearly defined. In this study, we examined the effects of spironolactone, losartan, and a combination of these two drugs on albuminuria, renal VEGF expression, and inflammatory and oxidative stress markers in a type 2 diabetic rat model.

Methods: Thirty-three Otsuka-Long-Evans-Tokushima-Fatty (OLETF) rats were divided into four groups and treated with different medication regimens from weeks 25 to 50; OLETF diabetic controls (n=5), spironolactone-treated (n=10), losartan-treated (n=9), and combination of spironolactone- and losartan-treated (n=9).

A case of autoimmune hypoglycemia complicated with diabetic ketoacidosis.

Autoimmune hypoglycemia is characterized by hyperinsulinemia, fasting hypoglycemia, and the presence of insulin auto- antibodies without previous exposure to exogenous insulin. We experienced a case of autoimmune hypoglycemia without diabetes mellitus or any evidence of insulinoma. The insulin auto-antibody and insulin receptor auto-antibody were present.
