Erika Kiss, Lídia Balogh, Péter Reismann
Classical galactosemia is an inherited disorder of the carbohydrate metabolism, most often caused by the deficient activity of the enzyme galactose-1-phosphate-uridyltransferase. Classical galactosemia presents in the neonatal period with life threatening illness after galactose is introduced in the diet. Symptoms and signs include poor feeding, vomiting, and diarrhea, weight loss, jaundice, hypotension, cataracts, hepatosplenomegaly, hepatocellular insufficiency, and encephalopathy. Since 1975 the testing for galactosemia is part of the neonatal screening program in Hungary...

BACKGROUND: Bronchopulmonary dysplasia remains a major problem in neonatal intensive care units. Persistent inflammation in the lungs is the most likely underlying pathogenesis. Corticosteroids have been used to prevent or treat bronchopulmonary dysplasia because of their potent anti-inflammatory effects. OBJECTIVES: To examine the relative benefits and adverse effects of systemic postnatal corticosteroids commenced within the first seven days of life for preterm infants at risk of developing bronchopulmonary dysplasia...

Hypotension or low blood pressure (BP) is a common problem in preterm neonates and has been associated with adverse short and long-term outcomes. Deciding when and whether to treat hypotension relies on an understanding of the relations between blood pressure and brain function. This study aims to investigate the interaction between BP and multichannel EEG in preterm infants less than 32 weeks gestational age. The mutual information is chosen to model interaction. This measure is independent of absolute values of BP and electroencephalography (EEG) power and quantifies the level of coupling between the short-term dynamics in both signals...

Sudden Infant Death Syndrome (SIDS) is associated with serotonin (5-HT) neuron abnormalities. There is evidence of autonomic dysfunction during sleep in infants eventually succumbing to SIDS, as well as cardiovascular collapse prior to death. Neonatal rodents deficient in central 5-HT display hypotension and bradycardia. We hypothesized that central 5-HT reduces cardiac vagal tone and increases sympathetic vascular tone and, given the firing pattern of 5-HT neurons, that these effects are greater in quiet sleep (QS) than in active sleep (AS)...

Magnesium (Mg) is an essential mineral in the body, impacting the synthesis of biomacromolecules, bone matrix development, energy production, as well as heart, nerve, and muscle function. Although the importance of Mg is evident, reference values for serum Mg (sMg) in pediatric patients (more specifically, in neonates) are not well established. This systematic literature review and meta-analysis (using 47 eligible studies) aims to quantify normal and tolerable ranges of sMg concentrations during the neonatal period and to highlight the factors influencing Mg levels and the importance of regulating sMg levels during pregnancy and birth...

BACKGROUND: Maternal inhalation of 35-40% oxygen concentration has no significant effect on foetal partial pressure of oxygen, and 60-100% produced maternal and foetal hyperoxia with increased free radical activity. The benefit of 50% maternal oxygen inhalation on foetal oxygenation, oxidant stress and total antioxidant status (TAS) during Caesarean section (CS) has not been simultaneously evaluated. METHODS: In this prospective, randomized, controlled trial 120 ASA physical status I-II, term pregnant women were recruited to elective CS (n = 60) and emergency CS (n = 60) and received either 50% oxygen or air inhalation following subarachnoid block (SAB)...

BACKGROUND: Despite the optimization of neonatal assistance, severe retinopathy of prematurity (ROP, stage III-IV) remains a common condition among preterm infants. Laser photocoagulation usually requires general anesthesia and intubation, but extubation can be difficult and these infants often affected by chronic lung disease. We retrospectively evaluated the clinical charts of 13 neonates that were sedated with propofol in association with fentanyl for the laser treatment of ROP. This protocol was introduced in our unit to avoid intubation and minimize side effects of anesthesia and ventilation...

BACKGROUND: Spinal anesthesia for cesarean delivery is associated with a high incidence of hypotension. Phenylephrine results in higher umbilical artery pH than ephedrine when used to prevent or treat hypotension in healthy women. We hypothesized that phenylephrine compared to ephedrine would result in higher umbilical artery pH in women with preeclampsia undergoing cesarean delivery with spinal anesthesia. METHODS: This study was a randomized double-blind clinical trial...

BACKGROUND: Studies in healthy patients undergoing elective caesarean delivery show that, compared with phenylephrine, ephedrine used to treat spinal hypotension is associated with increased fetal acidosis. This has not been investigated prospectively in women with severe preeclampsia. METHODS: Patients with preeclampsia requiring caesarean delivery for a non-reassuring fetal heart tracing were randomised to receive either bolus ephedrine (7.5-15mg) or phenylephrine (50-100µg), to treat spinal hypotension...

AIM: Piglets models have often been used to study the effects of dopamine infusion on hypotension in neonates. However, piglets need higher doses of dopamine than neonates to increase blood pressure. We investigated whether this difference was due to interspecific difference in dopamine pharmacokinetics. METHODS: Arterial blood samples were drawn from six neonates admitted to the neonatal intensive care unit of Copenhagen University Hospital and 20 newborn piglets during continuous dopamine infusion...

BACKGROUND: About 25% of hypotensive ELBW infants are refractory to intravascular volume expansion and inotropic drugs (VI) and require hydrocortisone (HC). Such neonates suffer from complications of prolonged hypotension and extended therapy with VI. ELBW infants with refractory hypotension (RH) are clinically and biochemically indistinguishable from those who respond to VI. OBJECTIVE: Early identification and differentiation of ELBW infants susceptible to steroid dependent hypotension from those who respond to inotropic medications...
