[Skin lesions in a 1,000 newborns. A case and control study]

Area of Science:

• Neonatal Dermatology
• Pediatric Skin Conditions
• Public Health

Background:

• Cutaneous alterations are frequent in newborns, yet specific data for Mexican neonates are lacking.
• Previous studies have not reliably characterized the types and prevalence of neonatal skin diseases in Mexico.

Purpose of the Study:

• To prospectively analyze the types and frequency of cutaneous lesions in Mexican newborns.
• To compare the incidence of skin conditions between well-baby and sick-baby nurseries.

Main Methods:

• A 6-month prospective study involving 1,000 neonates (790 well-baby, 220 sick-baby).
• Systematic analysis of cutaneous lesions present during the neonatal period.
• Statistical comparison using the Chi-squared (X2) method.

Main Results:

• 100% of neonates presented with 2-10 distinct cutaneous lesions.
• The majority of identified skin diseases were transient.
• Birthmarks and malformations were less frequent findings.
• No statistically significant difference in lesion prevalence was observed between well-baby and sick-baby groups (p > 0.1).

Conclusions:

• All neonates in the study population exhibited cutaneous lesions, predominantly transient ones.
• The study establishes a baseline for neonatal skin conditions in Mexican newborns.
• Findings suggest routine neonatal skin assessments are warranted, with most lesions resolving spontaneously.
