Hidranencefalia en un recién nacido por toxoplasmosis congénita / Hydroanencephalia in a newborn due to congenital toxoplasmosis

A case is described of a full-term newborn with hydroanencephalia due to congenital toxoplasmosis. Prenatal diagnosis had been made. The infection was supposedly acquired in the early stages of the pregnancy, the mother presented positive serology for active infection. The newborn presented elevated specific IgM. Fetal and newborn MRI was compatible with hydrancencephalia. The newborn presented macrocephalia, cataracts, abnormal archaic reflexes, hypotonia, thermoregulation abnormalities, and altered spinal fluid. Due to the severity and rarity of this clinical picture, and an absence of a national detection program, the possibility of offering mothers the possibility of detecting this illness is highlighted.

Se presenta el caso de un recién nacido de término con hidranencefalia por toxoplasmosis congénita con diagnóstico prenatal, el cual habría adquirido su infección en forma precoz durante el embarazo. Destaca madre con serología positiva para infección activa. Recién Nacido (RN) con IgM específica elevada. Resonancia Magnética fetal y del neonato compatible con hidranencefalia. RN con macrocefalia, catarata, reflejos arcaicos anormales, hipotonía, alteración del la termorregulación y LCR alterado. Frente a la gravedad y lo inusual del cuadro clínico y considerando la ausencia de un programa nacional de tamizaje se destaca la importancia de ofrecer a la madre embarazada la posibilidad de detección precoz y prevención de esta enfermedad frente a las severas complicaciones neurológicas de esta infección congénita.

Oxigenación con membrana extracorpórea en pacientes pediátricos: Comunicación de los 3 primeros casos tratados / Extracorporeal membrane oxygenation (ECMO): Consolidation of a neonatal-pediatric program in Chile and report of three cases

Extracorporeal membrane oxygenation (ECMO) improves survival in neonatal and pediatric patients with reversible severe respiratory or cardiac failure, in whom intensive treatment fails. Since 1999, a multidisciplinary team is trained to form the first neonatal-pediatric ECMO center in Chile, according to the norms of the Extracorporeal Life Support Organization (ELSO). During 2003 the first three patients were admitted to the program: a male newborn with pulmonary hypertension, a 38 days old female operated for a total anomalous pulmonary venous connection and a 3 months old male with a severe pneumonia caused by respiratory syncytial virus. They remained in ECMO for five, seven and nine days respectively and all survived to the procedure. No neurological complications were observed after one and a half year of follow up. This consolidates the first national neonatal-pediatric ECMO program, associated to ELSO. Up to date, twelve patients have been admitted to the program.
