Targeting Lower Serum Trough Concentrations: A New Gentamicin Dosing Strategy for Suspected Neonatal Early-Onset Sepsis.

Objective: Neonatal gentamicin dosing algorithms are not designed to achieve serum trough concentrations ≤1 mcg/mL. The purpose of our study was to evaluate a new gentamicin algorithm based on serum creatinine (SCr) and gestational age (GA) designed to achieve serum gentamicin trough concentrations ≤1 mcg/mL.

Methods: A retrospective cohort study was conducted in a level IIIB neonatal intensive care unit.

Empirical gentamicin dosing based on serum creatinine levels in premature and term neonates.

Purpose: Empirical gentamicin dosing based on serum creatinine (SCr) levels in premature and term neonates was evaluated.

Methods: This single-center, retrospective cohort study was conducted in a standalone children's hospital with a level IIIB, 44-bed neonatal intensive care unit (NICU). Data were abstracted and collected for all neonates admitted to the NICU from March 5, 2012, through March 5, 2014.

Adrenal Hemorrhage in Neonates: Unusual Presentation.

Adrenal hemorrhage (AH) is a relatively uncommon condition in newborns. It may be asymptomatic or may present with flank abdominal mass, anemia, jaundice, or rarely as scrotal bruising or hematoma. We report two cases of AH in neonates; the first presented with scrotal hematoma and the second with adrenal mass associated with hypertension and oliguria, primarily secondary to coincidental renal vein thrombosis.

Neonatal eosinophilic gastroenteritis: possible in utero sensitization to cow's milk protein.

Rectal bleeding in neonates is an alarming sign that suggests a possible serious underlying condition, such as infection or bleeding disorder that would necessitate hospitalization and prompt intervention. We report a case of eosinophilic gastroenteritis caused by cow's milk protein allergy in a one-day- old infant, who presented with frankly bloody stools associated with massive gastrointestinal and peripheral blood eosinophilia prior to initiation of enteral feedings. The patient's outcome was favorable, with complete spontaneous recovery in one week, after a period of bowel rest, parenteral nutrition, and use of amino acid formula.

Neonatal cardiac tamponade and pleural effusion resolved with chest tube placement.

Pericardial effusion and cardiac tamponade secondary to umbilical venous catheterization are rare complications but potentially fatal. This article reports a case of cardiac tamponade and right pleural effusion secondary to transudation of hyperosmolar fluid from an appropriately placed umbilical venous catheter. The infant survived as a result of early diagnosis by echocardiography and urgent chest tube placement that drained both pleural and pericardial effusions.
