Cutaneous lesions and disorders in healthy neonates and their relationships with maternal-neonatal factors: a cross-sectional study.

BACKGROUND: Cutaneous lesions are very common in neonates. Although a number of studies have reported on their incidence, very little is known about the factors that influence them. We set out to investigate a large population of neonates with the aims of achieving an overall picture of neonatal skin manifestations, and examining their relationships with various maternal, neonatal and perinatal factors. METHODS: This study was conducted on neonates born at the Department of Obstetrics and Gynaecology at the University of Szeged between June 2013 and July 2015. A total of 4658 consecutive infants underwent a whole-body skin examination within the first 72 hours of extrauterine life. The official neonatal medical charts were used to collect data on the history of the participating neonates and on maternal factors. RESULTS: 74.35% of the neonates exhibited at least one skin manifestation. The major diagnosis groups were transient, benign cutaneous lesions; vascular lesions; traumatic, iatrogenic, congenital or acquired disorders with skin injuries; pigmented lesions; and developmental abnormalities or benign skin tumours. The relationships between the skin findings and six neonatal or maternal factors were examined: gender, gestational age and birth weight of the neonates; maternal age and the number of previous pregnancies of the mothers, and mode and circumstances of the delivery. CONCLUSIONS: We found several significant correlations between the examined maternal/neonatal factors and the occurrence of birthmarks and neonatal skin disorders. Of course, further studies are required to confirm and better understand these associations.

INTRODUCTION: At present there are no exact epidemiologic data on the prevalence of neonatal skin disorders and birth marks in Hungary. AIM: The aim of the authors was to investigate the prevalence of skin disorders in mature healthy neonates after birth. METHOD: The survey was carried out in the Neonatal Care Unit at the Department of Obstetrics and Gynaecology at the University of Szeged between April, 2012 and May, 2013. RESULTS: A total of 2289 newborn infants underwent whole-body screening skin examinations. At least one skin manifestation was found in 63% of the neonates. The major groups of skin disorders were transient benign cutaneous lesions, vascular lesions, pigmented lesions, traumatic, iatrogenic, congenital or acquired disorders with skin injuries, developmental abnormalities and benign skin tumours. The most frequent transient cutaneous lesions were erythema toxicum neonatorum, sebaceous hyperplasia and desquamation. The most common vascular lesions were naevus simplex, haemangioma and haemangioma precursor lesion, while the most frequently observed pigmented lesions were congenital melanocytic naevi and Mongolian spot. CONCLUSIONS: In the vast majority of cases, special treatment was not necessary, but 5.27% of the neonates required local dermatologic therapy, and in 9.2% of neonates follow up was recommended.
