Supernumerary nipples and renal anomalies

Area of Science:

• Pediatrics
• Medical Genetics
• Human Biology

Background:

• Supernumerary nipples, also known as accessory nipples, are a relatively common congenital anomaly.
• Previous research suggests a potential association between supernumerary nipples and urogenital malformations.

Purpose of the Study:

• To investigate the prevalence of supernumerary nipples in different pediatric age groups.
• To determine if there is a statistically significant correlation between supernumerary nipples and renal malformations.

Main Methods:

• A total of 504 supernumerary nipples were identified in newborn infants, schoolchildren, and pediatric patients.
• Renal malformations were assessed using ultrasound in children with supernumerary nipples and in control groups.
• Control groups included acutely ill pediatric patients and newborn infants undergoing routine ultrasound screening.

Main Results:

• The prevalence of supernumerary nipples was 4.29% in newborn infants and 5.86% in schoolchildren.
• Renal anomaly prevalence was 3.74% in children with supernumerary nipples versus 3.17% in controls.
• In newborn infants, renal anomaly prevalence was 2.86% with supernumerary nipples versus 1.89% in controls.

Conclusions:

• The study found no significant difference in the prevalence of renal malformations between individuals with and without supernumerary nipples.
• The findings suggest that supernumerary nipples may not be a reliable indicator of underlying renal anomalies in pediatric populations.
