Summary
Newborn filiform periungual hyperkeratosis (NFPH) affects nearly half of neonates, presenting as hard, nail fold elements. Early detection is crucial to prevent infections like acute paronychia.
Area of Science:
- Neonatal dermatology
- Dermatological conditions in newborns
Background:
- Newborn filiform periungual hyperkeratosis (NFPH) is a condition with unknown incidence and prevalence in neonates.
- Early diagnosis and treatment are vital to prevent complications such as acute paronychia.
Purpose of the Study:
- To describe the characteristics of NFPH in neonates.
- To determine the prevalence of NFPH in a neonatal population.
Main Methods:
- Prospective observational study.
- Inclusion of 100 neonates born in a referral hospital in Buenos Aires.
- Clinical examination for NFPH assessment.
Main Results:
- NFPH was found in 46% of the 100 neonates studied.
- The condition presented as hard, filiform elements, predominantly in bilateral lateral nail folds.
- Prevalence was higher on the right hand, with erosions noted due to easy detachment; two cases of secondary acute paronychia were treated successfully.
Conclusions:
- Clinical examination is important for screening NFPH in neonates.
- NFPH is a local factor predisposing neonatal patients to infection.
- Prompt identification and management can prevent complications.
