Some renal parameters have been studied in newborns with respiratory distress syndrome (RDS). During the first 24 h, the serum creatinine level of the severe cases of RDS are significantly increased, decreasing gradually with improvement of the RDS and reaching normal values within 10 days. Blood urea nitrogen remained unchanged. In the milder cases of RDS, the serum creatinine also showed a slighter increase, which became normal within 4 days after birth. During the acute phase of RDS, there is a reversible impairment in the renal function, which correlates with the degree of hypoxia, hypercapnia and acidosis determined by the primary disease.

The authors are reporting a typical case of congenital varicella syndrome following maternal varicella during the 17th week of pregnancy. At birth, the newborn showed necrotic bullae on the skin that healed later with characteristic scars. Other typical anomalies, i.e. hypoplastic limbs with muscular atrophy and clubfoot, intrauterine atrophy, dysphagia and anisocoria were also found. In view of the risk of serious malformations following intrauterine varicella infection attempts should be made to prevent varicella zoster virus infection during pregnancy.
