We report the case of a one-day-old newborn infant, female, birth weight 1900 g, gestational age 36 weeks presenting with necrotizing fasciitis caused by E. coli and Morganella morganii. The newborn was allowed to fall into the toilet bowl during a domestic delivery. The initial lesion was observed at 24 hours of life on the left leg at the site of the venipuncture for the administration of hypertonic glucose solution. Despite early treatment, a rapid progression occurred resulting in a fatal outcome. We call attention to the risk presented by this serious complication in newborns with a contaminated delivery, and highlight the site of the lesion and causal agents. Necrotizing fasciitis occurs predominantly in adult patients. The initiating site is usually a local trauma or a surgical wound. In children, the disease is not common; however, frequently the clinical course is fatal 1 . The mortality rate among pediatric patients ranges from 10% to 60% 2 . During the neonatal period, the occurrence of necrotizing fasciitis is rare and is generally associated with other infections, such as omphalitis and mammary infection 3 . Mortality is high, reaching over 70%, even with precocious diagnosis and treatment 4 . These aspects of the disease's behavior demonstrate the importance of bearing in mind the predisposing factors and rigorous vigilance needed to treat the at-risk newborn. This case report describes our experience with a newborn with necrotizing fasciitis that followed a massive contamination during the delivery. CASE REPORTThe patient was a one-day-old girl, with a birth weight of 1900 g and a gestational age 36 weeks. The mother was 29 years old, and this was her second gestation without prenatal care. The birth took place at home, and the newborn was allowed to fall into the toilet bowl during delivery; the umbilical cord was severed with domestic scissors. Shortly after birth, the newborn was taken to the hospital where she received her first medical care and intravenous penicillin and amikacin therapy. At 90 minutes of life, she presented with hypoglycemia, necessitating intravenous infusion of 10% glucose. At 24 hours of life, hyperemia and edema of the left leg were observed at the site of the venipuncture and infiltration of intravenous solution. The clinical course was marked by a rapid deterioration of the lesion's appearance and extension. The infant was transferred to the Neonatal Intensive Care Unit (NICU) of the Children's Institute because of her worsening clinical course. On admission, she was in a poor general state, groaning, with decreased peripheral perfusion, an axillary temperature of 36°C, tachycardia (160 beats/min), tachypnea (88 breaths/min), abdominal distention, her
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
