Readmission for neonatal hyperbilirubinemia in an area with a high prevalence of glucose-6-phosphate dehydrogenase deficiency: A hospital-based retrospective study.

Background: Hyperbilirubinemia is one of the most common causes of neonatal readmission to hospital.

Aims: To assess risk factors for hyperbilirubinemia among neonates readmitted for this condition and the ratio of the mean corpuscular hemoglobin concentration (MCHC) to the mean corpuscular volume (MCV).

Methods: We retrospectively studied the clinical and laboratory findings, management and possible risk factors for hyperbilirubinemia in 301 neonates born at ≥35 weeks gestation and readmitted to hospital owing to hyperbilirubinemia over five years.

The syndrome dysmorphic facies, renal agenesis, ambiguous genitalia, microcephaly, polydactyly and lissencephaly (DREAM-PL): Report of two additional patients.

We have recently described a newly recognized syndromic form of congenital microcephaly as part of a large cohort of apparently novel dysmorphic syndromes. The reported Saudi Arabian patients have severe primary microcephaly, ambiguous male genitalia, dysmorphic facies, polydactyly, and renal agenesis. The same homozygous CTU2 mutation was identified in all patients.

The effect of dobutamine on platelet aggregatory function in newborn piglets with hypoxia and reoxygenation.

Dobutamine, a beta-adrenoceptor agonist that is often used to treat myocardial dysfunction in asphyxiated neonates, may act on the adrenoceptors of platelets resulting in activation. Little information is available on the effect and mechanistic pathway of dobutamine on the platelet aggregatory function in neonatal asphyxia. Newborn piglets were acutely instrumented and exposed to hypoxia for 2 h and reoxygenation for 4 h.

Systemic and regional hemodynamic effects of high-dose epinephrine infusion in hypoxic piglets resuscitated with 100% oxygen.

Shock and poor regional perfusion are common in asphyxiated neonates. We compared the systemic and regional hemodynamic effects of high-dose epinephrine (E) with those of dopamine combined with low-dose epinephrine (DE) infusions in a neonatal model of hypoxia-reoxygenation. Neonatal piglets (1-3 days, 1.

The hemodynamic effects of dobutamine during reoxygenation after hypoxia: a dose-response study in newborn pigs.

Asphyxiated neonates usually have myocardial stunning and hypotension and require inotropic support. A randomized controlled study was designed to examine the dose-response effect of dobutamine (5-20 microg x kg(-1) x min(-1)) on systemic and regional circulations and oxygen metabolism in a neonatal swine model of hypoxia/reoxygenation. Thirty-eight anesthetized newborn piglets were acutely instrumented for continuous monitoring of heart rate, systemic and pulmonary arterial pressures, and pulmonary (surrogate for cardiac index), right common carotid, and superior mesenteric and left renal arterial flows.
