Index of Suspicion in the Nursery

Abstract

A 2.94-kg male infant is born at 39 weeks to a 19-year-old G1P0 woman. The pregnancy was complicated by gestational diabetes. The woman had no significant past medical history, including sexually transmitted diseases, and no significant family history. Prenatal screening for group B Streptococcus, Chlamydia, gonorrhea, syphilis, and human immunodeficiency virus were negative. Delivery is complicated by prolonged rupture of membranes for 18 hours, maternal fever (temperature of 38.9°C), and failure to progress. The baby is delivered in good condition by cesarean section. Apgar scores are 8 at 1 minute and 9 at 5 minutes. Vital signs are within normal limits, and physical examination at birth shows no abnormal findings of note. The infant is admitted to the newborn nursery for observation. Blood culture is drawn and empiric antibiotics are started. Hematologic parameters are within normal limits and C-reactive protein measures 0.5 mg/dL. Antibiotics are continued for suspected chorioamnionitis. He is otherwise feeding well, euthermic, and looking well, and his blood culture remains negative. On postnatal day 7, the nurse notices two vesicular skin lesions: one on the right side of the forehead (Fig. 1) and the other on the vertex of the scalp (Fig. 2). Both comprise groups of clustered tiny vesicles that have minimal erythema at their bases. Vital signs and physical examination findings are within normal limits. The result of a simple test supports the diagnosis, and further laboratory investigations confirm the cause. Figure 1. Vesicular lesions on the right side of the forehead. Figure 2.

Early diagnosis and management are crucial …
