[THE FETAL MIDDLE CEREBRAL ARTERY PEAK SYSTOLIC VELOCITY AS A PEDICTOR OF FETAL ANEMIA IN RH-ALLOIMMUNIZED PREGNANCY].

Unlabelled: Rh-isoimmunization is a pathological condition in which the fetal red blood cells of a Rh (+) fetus are destroyed by the isoantibodies of a Rh (-) woman sensitized in a previous event. Despite of the wide spread implementation of anti D-gammaglobolin prophylaxis this is still the most common cause for fetal anemia. Recently, sonographic measurement of the fetal middle cerebral artery peak systolic velocity (MCA-PSV) has been shown to be an accurate non-invasive test to predict low fetal hemoglobin levels.

[BRONCHOPULMONARY DYSPLASIA IN VERY LOW BIRTH WEIGHT INFANTS--THE OLD NEW PROBLEM].

Background: The advances in perinatal intensive care have increased the survival rate of extremely low birthweight (ELBW) and gestational age infants. Among them the risk of developing bronchopulmonary dysplasia (BPD) remains high.

Aim: To evaluate the frequency of BPD by birthweight and gestational age, to identify the main postnatal risk factors and the associated comorbidities.

[Perforated neonatal appendicitis in a preterm newborn].

Unlabelled: Abstract: Appendicitis is common in paediatric surgical praxis, but extremely rare in newborn infants.

Case Report: We report a premature male newborn from a twin pregnancy with gestational age of 31(+4) weeks, birth-weight 1580g, who underwent a laparotomy because of perforation. The baby was admitted to NICU after birth with transitory respiratory failure and early onset neonatal sepsis.

[Pulmonary hypertension of the newborn--recent advances in the management and treatment].

Pulmonary hypertension of the newborn is a clinical syndrome with diverse etiology in which the transition from fetal circulation with high pulmonary vascular resistance to postnatal circulation with low pulmonary vascular resistance failed. The persistence of high pulmonary vascular pressure leads to right-left shunts and marked cyanosis. Despite of the advances in neonatology, the treatment of some forms of PPHN is often difficult and mortality rate remains high.

[Neonatal bacteremia--frequency, spectrum of organisms and correlation between clinical symptoms and laboratory data for early onset sepsis].

Unlabelled: Improved obstetrical management and evidence-based peripartum antimicrobial therapy in the last decades reduce the frequency of early-onset neonatal sepsis (EONS) and improve the outcome. The spectrum of the microrganisms is different according to regions, countries and periods of time. Appropriate diagnosis and treatment improve the outcome.
