[Influence of neonatal and maternal factors on the prevalence of vernix caseosa]. / Influencia de los factores neonatales y maternos en la prevalencia de vérnix caseosa.

At birth, vernix caseosa can cover the whole body surface or accumulate only on the back and in the skin folds. Interest in its composition and function and its possible applications in adults has increased in recent years. The objective of this study was to determine the prevalence of vernix caseosa in newborn infants in the health care area of Ferrol, Spain, and to assess its relationship with neonatal and maternal factors. We performed a prospective study of 1000 newborns seen within the first 3 days of life in our hospital. Vernix caseosa was observed in 42.9% of cases. The clinical profile associated with the presence of vernix caseosa was the following: healthy newborn girl with a high birth weight, born at term by normal vaginal delivery to a multiparous mother who had received medication and dietary supplements during pregnancy. The absence of vernix caseosa was associated with the presence of physiological scaling of the newborn and erythema toxicum neonatorum.

Estudio prospectivo de la hiperpigmentación del área genital en recién nacidos españoles: frecuencia y factores predisponentes / Prospective study of hyperpigmentation of the genital area in Spanish newborns: frequency and predisposing factors

Realizamos un estudio prospectivo de 1.000 recién nacidos vistos en las primeras 72 horas de vida en el Área Sanitaria de Ferrol (noroeste de España)con el objetivo de conocer la prevalencia de la hiperpigmentación del área genital y ver como influyen, en su aparición, los factores neonatales y maternos, el momento de exploración y la modalidad de parto. La frecuencia de la hiperpigmentación genital fue del 15,3%. Encontramos una prevalencia superior en los neonatos no caucásicos (p = 0,000) de sexo masculino (p = 0,000), con mancha mongólica (p = 0,000), nacidos por vía vaginal (p =0,030) y con madre menor de 30 años (p = 0,006) y con al menos 2 gestaciones previas (p = 0,015) (AU)

We performed a prospective study of 1,000 neonates investigated in the first 72 hours of life in the Health Area of Ferrol (northwest of Spain), in order to assess the prevalence of hyperpigmentation of the genital area, the influence of different maternal and neonatal parameters, day of neonatalexploration and type of delivery. Overall frequency of hyperpigmentation was 15.3%. We found a higher prevalence of this dermatosis in non-Caucasian infants (p = 0.000) of male sex (p = 0.000), with Mongolian spot (p = 0.000), vaginal delivery (p = 0.030), maternal age below 30 years (p =0.006) and at least two previous pregnancies (p = 0.015) (AU)

Influencia de los factores neonatales y maternos en la prevalencia de vérnix caseosa / Influence of Neonatal and Maternal Factors on the Prevalence of Vernix Caseosa

Al nacimiento la vérnix caseosa puede cubrir toda la superficie corporal o acumularse sólo en la espalda y los pliegues. En los últimos años ha aumentado el interés por su composición, funciones y aplicaciones en la edad adulta. Nuestro objetivo fue conocer la prevalencia de la vérnix caseosa en los recién nacidos del Área Sanitaria de Ferrol, y ver cómo repercutían los parámetros neonatales y maternos en su desarrollo. Realizamos un estudio prospectivo de 1.000 recién nacidos vistos en los primeros tres días de vida en nuestro hospital. Encontramos vérnix caseosa en el 49,2% de los neonatos. El perfil clínico de presencia de vérnix caseosa sería: recién nacido de sexo femenino, sano, a término, con peso elevado producto de una gestante no primigesta, con ingesta de fármacos y suplementos dietéticos durante el embarazo sometida a un parto eutócico. Existe relación entre ausencia de vérnix caseosa y la presencia de descamación fisiológica y de eritema tóxico neonatal (AU)
