The hospital charts of 274 infants under 6 months of age with culture-proved respiratory syncytial virus infections were reviewed. Fifty-six infants (20.4%) demonstrated apnea in association with RSV infection. Predisposing factors significantly correlated with apnea included premature birth and young chronologic age at the time of virus infection. The(More)
We retrospectively reviewed the manifestations of influenza A2 in 83 hospitalized young children. Our purpose was to define the spectrum of clinical illness in this age group. Findings included fever (91%), vomiting or diarrhea (49%), pharyngitis (34%), pneumonitis (29%), otitis media (24%), conjunctivitis (13%), croup (13%), and bronchiolitis (6%).(More)
Forty-one children less than 6 months of age from whom respiratory syncytial virus (RSV) was isolated were divided into groups of varying severity of illness. No relationship was demonstrated between severity of illness and the complement fixation titer to RSV in cord sera, acute sera, or convalescent sera. An increase in IgM level of greater or equal to 15(More)
The potential impact of using a rapid diagnostic test (Strep A OIA) on detection and treatment of group A beta-hemolytic streptococcal (GABHS) pharyngitis in a large-volume pediatric and adolescent clinic was examined. Of 519 swabs processed for both culture and the OIA test, 114 were culture-positive for GABHS compared with 133 positive by the OIA test,(More)
In case-control studies of three epidemics of neonatal necrotizing enterocolitis (NEC) in three different high-risk nurseries in three states, no particular risk factor was associated with affected infants or their mothers. Epidemic cases had higher birth weights and Apgar scores and fewer perinatal difficulties than those previously reported for sporadic(More)
Six infants with disseminated HSV had no mucocutaneous lesions at any time during the course of the illness. These infants presented with lethargy, poor feeding, apnea, acidosis, and hepatomegaly. The diagnosis of HSV was made by culturing the infant's oropharynx and blood, and the maternal cervix. Eight infants with HSV encephalitis had no skin, eye, or(More)
