Nelson Syndrome: A Case Report and Literature Review.

Objective: Nelson syndrome (NS) is a rare clinical disorder that can occur after total bilateral adrenalectomy (TBA), performed as a treatment for Cushing disease. NS is defined as the accelerated growth of an adrenocorticotropic hormone-producing pituitary adenoma. Our objective is to describe a case of NS and discuss it based on existing knowledge of this syndrome.

Idioventricular rhythm and shock after a honeybee sting.

Objective: The objective of this study was to describe the case of a 19-year-old male presenting with bradycardia and hypotension after a honeybee sting making a review of the literature and pathophysiology of the cardiovascular and electrocardiogram (EKG) changes after a bee sting.

Methods: The patient's airway was inspected and secured. Electrocardiogram with an idioventricular rhythm at 41' bpm.

Fibroblast growth factor 21 is associated with increased serum total antioxidant capacity and oxidized lipoproteins in humans with different stages of chronic kidney disease.

Background And Aims: Oxidative stress (OS) induces the production of fibroblast growth factor 21 (FGF21). Previous data have revealed that FGF21 protects cells from OS injury and death, making it a potential therapeutic option for many diseases with increased OS. However, the association of this growth factor with OS markers in humans with chronic kidney disease (CKD) remains unknown.

Serum Uric Acid concentration is associated with insulin resistance and impaired insulin secretion in adults at risk for Type 2 Diabetes.

Aims: Insulin resistance (IR) predisposes to type 2 diabetes mellitus (T2DM). Although previous studies have associated serum uric acid concentration with IR in T2DM, its association with impaired insulin secretion and beta-cell dysfunction in subjects at risk for developing T2DM remains uncertain. Thus, we aimed to analyze the association of serum uric acid concentration with IR using surrogate insulin resistance/secretion and beta-cell function indices in subjects at risk for developing T2DM.
