Infected cephalohematoma of newborns: Experience in a medical center in Taiwan

Background : The objective of the present retrospective study was to clarify the clinical course, major pathogens, and other infections associated with infected cephalohematoma. Methods : From January 1978 to December 2003, records of all newborns were reviewed for evidence of an infected cephalohematoma, based either on local signs of infection or a diagnostic tap that yielded pus. Patients were divided into two groups: those seen in the early period (1978–1990) and in the late period (1991–2003). Results : Twenty‐eight newborns with infected cephalohematoma were identified, 14 each in the early and late periods. The mean age at onset was 17.8 ± 13.9 days. The most common local findings were erythema (79%), increasing size of the hematoma (68%), and a fluctuant mass (46%), while fever (64%), poor appetite (39%) and irritability (18%) were the common systemic signs. Common laboratory findings included leukocytosis (82%) and an elevated C‐reactive protein (61%). Escherichia coli was the most common pathogen (16 patients, 57%) and was isolated significantly more frequently in the late period (early period: 36%, late period: 79%, P
