Further studies are needed to employthis method as a non-invasive, indirect screening test for the screening of congenitaladrenal hyperplasia in male infants.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Aim: To evaluate the scrotal melanin density in infants using spectrometry and todetermine the correlation between spectrometric evaluations, physical examinationsand blood 17-hydroxyprogesterone levels.Material and methods: A total of 40 infants were enrolled to the study, 22 of whomwere diagnosed by a physician as having scrotal hyperpigmentation and 18 with normal scrotal pigmentation, who were admitted for the evaluation of prolonged jaundice.Age, gestational week, birth weight and scrotal pigmentation noted by the physicianwere recorded.
📊
Key Findings & Data:A correlationbetween the spectral measurements and the blood 17-hydroxyprogesterone levelwas determined by comparing spectral value in the wavelength range of 620-800 nmand 17-hydroxyprogesterone levels.Results: No statistically significant difference was observed between the groups whowere categorized by the physician as having “hyperpigmented” or “normal” scrotalcolor in terms of the infant’s age, gestational week, birth weight, 17-hydroxyprogesterone level or spectrometric values.
💡
Conclusion & Impact:Further studies are needed to employthis method as a non-invasive, indirect screening test for the screening of congenitaladrenal hyperplasia in male infants.

Abstract

Aim: To evaluate the scrotal melanin density in infants using spectrometry and todetermine the correlation between spectrometric evaluations, physical examinationsand blood 17-hydroxyprogesterone levels.Material and methods: A total of 40 infants were enrolled to the study, 22 of whomwere diagnosed by a physician as having scrotal hyperpigmentation and 18 with normal scrotal pigmentation, who were admitted for the evaluation of prolonged jaundice.Age, gestational week, birth weight and scrotal pigmentation noted by the physicianwere recorded. Spectral data were acquired from scrotum and thigh. A correlationbetween the spectral measurements and the blood 17-hydroxyprogesterone levelwas determined by comparing spectral value in the wavelength range of 620-800 nmand 17-hydroxyprogesterone levels.Results: No statistically significant difference was observed between the groups whowere categorized by the physician as having “hyperpigmented” or “normal” scrotalcolor in terms of the infant’s age, gestational week, birth weight, 17-hydroxyprogesterone level or spectrometric values. We observed a strong correlation between17-hydroxyprogesterone levels and spectrometric values in all groups.Conclusion: This preliminary study is the first one in the literature which evaluatesscrotal pigmentation with an objective spectrometric method and determines its relationship with 17-hydroxyprogesterone levels. Further studies are needed to employthis method as a non-invasive, indirect screening test for the screening of congenitaladrenal hyperplasia in male infants.

Özet

Amaç: Spektrometre ile bebeklerin skrotal melanin dansitesini değerlendirmek ve spektrometrik değerlendirme ile fizik muayene ve kan 17-hidroksiprogesteron düzeyleri arasındaki ilişkiyi belirlemektir. Gereç ve Yöntemler: Çalışmaya skrotal hiperpigmentasyonu olduğu düşünülen 22 olgu ile uzamış sarılık nedeniyle başvuran normal skrotal pigmentasyona sahip 18 olgu olmak üzere toplam 40 bebek dahil edildi. Olguların yaşı, gestasyon haftası, doğum ağırlığı, anne yaşı, skrotum rengi kayıt altına alındı. Spektral veriler skrotumdan ve uyluktan elde edildi. Spektral ölçümler ve kan 17- hidroksiprogesteron seviyesi arasındaki korelasyon, 620-800 nm dalga boyu aralığındaki spektral değer ve 17- hidroksiprogesteron seviyelerinin karşılaştırılmasıyla incelendi. Bulgular: Skrotal hiperpigmentasyonu saptanan ve saptanmayan grup arasında anne-olgu yaşı, gestasyon haftası, doğum ağırlığı, 17-hidroksiprogesteron düzeyi ve spektrometri değeri arasında istatistiksel olarak anlamlı farklılık saptanmadı. Tüm gruplarda 17-hidroksiprogesteron düzeyleri ile spektrometrik değerler arasında güçlü bir korelasyon gözlemledik. Sonuç: Çalışmamız, literatürde spektrometre değerleriyle skrotal pigmentasyonun nesnel bir ölçüt hale getirildiği, 17-hidroksiprogesteron ile ilişkisinin incelendiği, gelecekte erkek bebeklerde konjenital adrenal hiperplazi taramasına dolaylı yoldan yardımcı olabilecek bir çalışmadır.
