Epidemiología y factores predisponentes de los hallazgos dermatológicos en neonatos de Uruguay / Neonatal Dermatologic Findings in Uruguay: Epidemiology and Predisposing Factors

Introducción: La piel es fundamental en la transición de la vida intrauterina a la extrauterina. El recién nacido presenta cambios fisiológicos, siendo frecuente observar hallazgos cutáneos benignos y transitorios que varían según las características maternas, neonatales y de la gestación. Objetivos: Estimar la frecuencia de distintos hallazgos dermatológicos en neonatos en las primeras 72h de vida e identificar la existencia de diferencias de proporciones estadísticamente significativas con factores neonatales, maternos y de la gestación. Métodos Se realizó un estudio descriptivo, observacional de corte transversal entre abril-julio 2015 y julio-noviembre de 2017 en la maternidad del Centro Hospitalario Pereira Rossell. Se incluyeron neonatos de hasta 72h de vida, a los que se les practicó un examen dermatológico completo. Se presenta la proporción de cada uno de los hallazgos con el intervalo de confianza (IC) correspondiente. Se analiza la relación entre los hallazgos y determinados factores asociados. Resultado Se incluyeron 2811 neonatos. El 100% presentó al menos un hallazgo a nivel de la piel. La mediana fue de 8 lesiones por paciente (rango intercuartílico: 6-9/mínimo-máximo: 1-16). De los 46 hallazgos explorados clínicamente se encontraron 42. Las lesiones benignas y transitorias correspondieron al 99,9%. Entre ellas se observó: lanugo 98% (IC: 97,7-98,7), descamación fisiológica 79,7% (IC: 78,2-81,1) e hiperplasia sebácea 73,3% (IC: 71,6-74,9). El lanugo (p=0,001), la descamación fisiológica (p<0,001) y el eritema tóxico neonatal (p=0,001) se observaron con más frecuencia en los neonatos de término y postérmino. La hiperplasia sebácea (p=0,001) y la hiperpigmentación transitoria neonatal (p<0,001) se encontraron con mayor frecuencia en varones (AU)

Background: The skin is a fundamental organ in the transition from intrauterine to extrauterine life. The newborn infant experiences physiological changes and often presents benign, transient skin characteristics that vary according to maternal, gestational, and neonatal factors. Objectives: To estimate the frequency of various dermatologic findings during the first 72hours of life and to identify their association with maternal, gestational, or neonatal factors. Methods Descriptive, observational, cross-sectional study from April to July 2015 and July to November 2017 in the maternity ward of Centro Hospitalario Pereira Rossell. We examined the skin of neonates within 72hours of birth. Proportions and 95% CI were calculated for all findings. Associations between findings and factors were analyzed. Results A total of 2811 neonates were included. We observed at least one neonatal skin finding in all of the neonates and found a median (interquartile range) of 8 (6-9) findings (minimum–maximum, 1-16). We observed 42 of the 46 possible characteristics we looked for; 99.9% of the findings were benign and transient. Among the findings were lanugo (98%; 95% CI, 97.7%-98.7%), physiological scaling (79.7%; 95% CI: 78.2%-81.1%), and sebaceous hyperplasia (73.3%; 95% CI: 71.6%-74.9%). Lanugo (P=.001), physiological scaling (P<.001), and erythema toxicum (P=.001) were observed significantly more often in full- and late-term neonates. Sebaceous hyperplasia (P=.001) and transient hyperpigmentation (P<.001) were found more often in newborn males. Erythema toxicum was more common after vaginal births (P=.008). Transient hyperpigmentation (P<.001) and dermal melanocytosis (P<.001) were seen more often in neonates of African descent (AU)

Transient hyperpigmentation (P<.001) and dermal melanocytosis (P<.001) were seen more often in neonates of African descent. CONCLUSIONS: All neonates have skin characteristics that are part of their adaptation to extrauterine life. Most are benign and transient. Maternal age, type of delivery, and certain neonatal factors such as gestational age, birth weight, sex, and ethnicity are associated with specific findings.

[First SIBEN clinical consensus: diagnostic and therapeutic approach to patent ductus arteriosus in premature newborns]. / Primer consenso clínico de SIBEN: enfoque diagnóstico y terapéutico del ductus arterioso permeable en recién nacidos pretérmino.

OBJECTIVE: To report the process and results of the first neonatal clinical consensus of the Ibero-American region. DESIGN AND METHODS: Two recognized experts in the field (Clyman and Van Overmeire) and 45 neonatologists from 23 countries were invited for active participation and collaboration. We developed 46 questions of clinical-physiological relevance in all aspects of patent ductus arteriosus (PDA). Guidelines for consensus process, literature search and future preparation of educational material and authorship were developed, reviewed and agreed by all. Participants from different countries were distributed in groups, and assigned to interact and work together to answer 3-5 questions, reviewing all global literature and local factors. Answers and summaries were received, collated and reviewed by 2 coordinators and the 2 experts. Participants and experts met in Granada, Spain for 4.5 h (lectures by experts, presentations by groups, discussion, all literature available). RESULTS: 31 neonatologists from 16 countries agreed to participate. Presentations by each group and general discussion were used to develop a consensus regarding: general management, availability of drugs (indomethacin vs. ibuprofen), costs, indications for echo/surgery, etc. Many steps were learnt by all present in a collaborative forum. CONCLUSIONS: This first consensus group of Ibero-American neonatologists SIBEN led to active and collaborative participation of neonatologists of 16 countries, improved education of all participants and ended with consensus development on clinical approaches to PDA. Furthermore, it provides recommendations for clinical care reached by consensus. Additionally, it will serve as a useful foundation for future SIBEN Consensus on other topics and it could become valuable as a model to decrease disparity in care and improve outcomes in this and other regions.
