Congenital syphilis (CS) is a disease transmitted by Treponema pallidum to the fetus by transplacental circulation, usually from the 20th week of gestation. In 2019, Mexico reported 372 cases, on the other hand, infection by Congenital Cytomegalovirus (cCMV) is not considered mandatory notification. We report the first neonatal case of Coinfection by T. pallidum and CMV according to the medical literature in spanish and english. The clinical case is a premature newborn born in the Hospital de la Mujer in Mexico City, pregnancy 1, 21-year-mother without prenatal control, female product is obtained vaginally, weight 1570 g (

Objectives: To analyse the effect of zinc supplementation in growth and nutritional status of a homogeneous group of newborns with intra uterine growth retardation and asymmetric growth. The effect of changes of zinc status on growth and leptin serum concentrations was also analysed. Population and methods: A double blind, randomised clinical trial was designed in order to detect differences in growth between zinc and placebo groups during the first 6 months of life. 31 infants were included either to the zinc group (n = 14) (38.8 ± 1.4 weeks GA, 2,171 ± 253 g body weight) or the placebo group (n = 17) (38.9 ± 1.1 weeks GA, 2,249 ± 220 g body weight). The zinc group received a supplement of 3 mg elemental zinc per day (as zinc sulphate). Results: There were not significant differences between groups for anthropometric measurements through the study period. We found a significant effect of the study group, in hair zinc concentrations, but not in serum zinc concentrations; post-hoc comparisons for hair zinc revealed that there were significant differences between groups at 1, 2, and 6 months of age. Changes in serum and hair zinc concentrations from baseline to 6 months, showed significant correlations with changes in weight/age and length/age z-scores, in the supplement group. Changes in leptin serum concentrations during follow-up, showed significant correlations with changes in sum of 4 skinfolds and weight/age z-score, in the placebo group. Changes in hair zinc concentration through the study period showed significant correlations with changes in leptin serum concentrations from baseline to 6 months of follow-up. Conclusions: In a homogeneous group of intra uterine growth retardation infants with asymmetric growth, 3 mg/day zinc supplementation do not show significant improvements in weight and length growth. Changes in zinc status were related with changes in weight and length during the first 6 months of life. Changes in leptin serum concentrations were related with changes in the anthropometric indices of body fat accretion.Objetivos: Valorar el efecto de la suplementación con cinc en el crecimiento y estado nutricional de un grupo homogéneo de recién nacidos con retraso de crecimiento intra-uterino asimétrico. También se analizó el efecto de los cambios en el status del cinc en el crecimiento y las concentraciones séricas de leptina. Población y método: Se diseñó un ensayo clínico randomizado y doble ciego, con el fin de detectar diferencias en el crecimiento entre los grupos recibiendo cinc o placebo, durante los seis primeros meses de vida. 31 niños fueron incluidos en el grupo cinc (n = 14) (38,8 ± 1,4 semanas edad gestacional, 2.171 ± 253 g peso) o grupo placebo (n = 17) (38,9 ± 1.1 semanas edad gestacional, 2.249 ± 220 g peso). El grupo cinc recibió un suplemento de 3 mg de cinc elemental por día (en forma de sulfato de cinc). Resultados: No hubo diferencias significativas entre ambos grupos en cuanto a las medidas antropométricas a lo largo del período de estudio. Se observó un efecto significativo del grupo de estudio, en las concentraciones de cinc en el pelo, pero no en las concentraciones séricas de cinc; las comparaciones post-hoc para el cinc del pelo pusieron de manifiesto que había diferencias significativas entre los grupos, en los meses 1, 2 y 6 de edad. Los cambios en las concentraciones de cinc en el suero y en el pelo, desde el inicio del estudio hasta los 6 meses, mostraron correlaciones estadísticamente significativas con los cambios en peso/edad y longitud/edad (puntuación típica), en el grupo que recibió el suplemento de cinc. Los cambios en las concentraciones séricas de leptina durante el seguimiento, mostraron correlaciones estadísticamente significativas para la suma de 4 pliegues y para peso/edad (puntuación típica), en el grupo placebo. Los cambios en las concentraciones de cinc en el pelo mostraron correlaciones estadísticamente significativas con los cambios en las concentraciones séricas de leptina, desde el inicio del estudio hasta los 6 meses de seguimiento. Conclusiones: En un grupo homogéneo de niños con retraso de crecimiento intra-uterino asimétrico, el suplemento de cinc a una dosis de 3 mg/día, no origina mejora significativa en el crecimiento en peso y longitud. Los cambios en el status de cinc se relacionaron con los cambios en peso y longitud durante los 6 primeros meses de vida. Los cambios en las concentraciones séricas de leptina se relacionaron con los cambios en los índices antropométricos de acúmulo de grasa corporal.

Introduction: The characteristics of catch-up growth in very low birth weight infants (VLBW) have not been clearly established. The aim of this study was to analyse the height catch-up and some associated factors in a cohort of VLBW (birth weight<1,500g) from birth to age 14 years., Methods: We obtained retrospective data on weight and height at birth and ages one, 2, 3, 4, 6, 8, 10, 12 and 14 years in a cohort of 170 VLBW. We compared these anthropometric values with those documented in a control group., Results: Thirty-seven children (21.8%) were born with an extremely low birth weight and 32 (18.8%) extremely preterm. At 10 years of age, 7% of VLBW (1,000-1,500g) and 35% of extremely low birth weight (<1,500g) children had short stature (P=.001). Almost all VLBW children who had a normal height at ages 2, 4 and 10 years had exhibited adequate weight catch-up in previous evaluations. We found that extremely low birth weight and extremely preterm were independent predictors for inadequate height catch-up., Conclusion: The growth pattern of VLBW children has specific characteristics. The catch-up in weight seems to be an important factor for catch-up in height, and therefore a thorough nutritional follow-up is recommended in these children., (Copyright © 2019 Asociación Española de Pediatría.
