Nail disease in neonatal abstinence syndrome.

Neonatal abstinence syndrome (NAS) incidence continues to rise in the United States due to increasing opioid use disorder in pregnancy. While cutaneous excoriations have been noted in NAS, there is a paucity of literature regarding abnormal nail findings in NAS. A retrospective, observational case series was conducted of twelve patients with NAS and abnormal nail findings who were admitted to the neonatal intensive care unit between January 1, 2018, and May 1, 2020. Twelve neonates (10 male, 2 female, mean gestational age at birth 38.1 weeks) with NAS diagnosis and abnormal nail findings were identified between January 1, 2018, and May 1, 2020. NAS was diagnosed by elevated Modified Finnegan Neonatal Abstinence Syndrome Tool (M-FNAST) scores. All patients required pharmacologic treatment for NAS with seven (58.3%) requiring phenobarbital in addition to first-line morphine. Common nail findings included periungual erythema, yellow crusting, desquamation of the proximal and/or distal lateral nail folds and sheared distal nail edges. Two patients (16.7%) required antibiotic treatment for paronychia. Peak M-FNAST scores were positively correlated with number of abnormal nail findings (r = .58, P = .047). Twelve neonates with severe NAS demonstrated similar nail abnormalities, likely secondary to NAS agitation and motor hyperactivity. Nail exams, therefore, are important in the setting of suspected or confirmed NAS to limit continued nail trauma and infection. Our findings also introduce an association between NAS severity and abnormal nail findings, which will require larger studies for further confirmation. © 2021 Wiley Periodicals LLC.
