RESUMEN
A nursery outbreak of varicella is reported. Serum from 200 parturient women and 131 of their offspring were studied for antibody to varicella-zoster (V-Z) virus to analyze their immunity to varicella. Antibody titers were measured by the sensitive fluorescent antibody to membrane antigen (FAMA) technique. It was found that approximately 5% to 16% of women of child-bearing age in New York City are susceptible to varicella. Women from Puerto Rico or other subtropical and tropical areas are more likely to be susceptible (16%) than others (5%). Infants born to mothers with detectable V-Z FAMA titers almost always had detectable V-Z antibody at birth. In serial serum specimens obtained from 67 initially seropositive babies during the first year of life, it was found that by 6 months of age most infants were no longer passively protected against varicella. These observations may explain why varicella is not uncommonly observed in young babies.

A tension pneumothorax requires immediate relief. Emergency evacuation of pneumothorax using a spring-loaded needle to prevent lung perforation is described. A case example is also presented. Over 3 years, this technique proved to be safe and easy to perform.

A 37 month review of the effects of glucocorticoids and uncompromised labor with atraumatic delivery on the incidence of respiratory distress syndrome (RDS) is presented. The incidence of RDS in the control and study population is not significantly different; however, the incidence of RDS in the control and study groups is markedly lower than the published figures for the same age and weight range. The low incidence of RDS in the control population is attributed to the avoidance of intrapartum hypoxia and stress during an uncompromised labor and atraumatic delivery.
