Implementation of an Intravenous Fluid Titration Algorithm to Treat Pediatric Diabetic Ketoacidosis.

Diabetic ketoacidosis (DKA) is a common cause of admission to the pediatric intensive care unit and many centers utilize the "two-bag system" to treat DKA. We developed an intravenous fluid (IVF) titration algorithm to standardize adjustments of the two bags. A retrospective cohort study was performed comparing 155 patients treated before and 175 patients treated after implementation of the IVF titration algorithm.

Decreased reverse T3 levels in neonates with central hypothyroidism.

Concern arises when a sick infant is found to have a low serum T4, normal thyroid hormone binding, and a nonelevated thyroid-stimulating hormone. Hypothyroxinemia in this situation can result from either euthyroid sick syndrome or central hypothyroidism. To help distinguish between these diagnostic possibilities, we have measured reverse T3 and other thyroid function chemistries in six neonates who have central hypothyroidism in association with hypopituitarism.

Adrenal responsiveness in very-low-birth-weight infants treated with dexamethasone.

This study was designed to investigate the effect of steroid administration in ill premature neonates. Twenty high-risk very-low-birth-weight (VLBW) infants [birth weight (BW) < or = 1,300 g] with a mean BW 948 +/- 220 g, gestational age (GA) 27 +/- 1.7 weeks underwent 1-hour ACTH (Cortrosyn) stimulation tests and determination of 17-hydroxyprogesterone (17OHP)/dehydroepiandrosterone sulfate (DHEAS) at 23.

Defective pancreatic alpha and beta cell secretion in thyrotoxicosis.

Pancreatic alpha and beta cell hormone secretion was studied in 11 patients with thyrotoxicosis before and in 7 patients after thyroid function was normalized with either prophylthiouracil or methimazole and propranolol (R). All had IV arginine and IV glucose infusions. Forty control subjects had IV arginine; 21 had IV glucose tests.
