Background:   There is no consensus among pediatric endocrinologists in using low-dose (LD) versus high-dose (HD) cosyntropin to test for secondary/tertiary adrenal insufficiency. This paper compares LD and HD cosyntropin stimulation testing in children for evaluation of hypothalamic-pituitary-adrenal axis (HPAA) and suggests a new peak cortisol cut-off value for LD stimulation testing to avoid false positivity.

Methods:   Data of 36 children receiving LD (1 µg) and HD (249 µg) cosyntropin consecutively during growth hormone (GH) stimulation testing were analyzed in two groups.

Background And Objectives: Although insulin pump therapy has been successful in adults, adolescents and school children, its use has been limited in young children. The purpose of this study was to evaluate the glycemic control, safety and efficacy of continuous subcutaneous insulin infusion via pump in young children (2-7 years old) with type 1 diabetes who were transitioned from twice-a-day insulin injection (neutral protamine Hagedorn/Lente + Humalog/Novalog) to insulin pump therapy. Hemoglobin A1c, BMI, average fasting blood glucose, episodes of severe hypoglycemia, episodes of diabetic ketoacidosis, episodes of lipohypertrophy, blood glucose variability, and number of sick day calls were compared before and after insulin pump therapy.
