Sitio: Comisión Local de Análisis de Mortalidad Infantil. Grecia. Material y Métodos: Estudio de tipo correlacional retro-prospectivo y longitudinal de 35 casos de muertes infantiles del cantón de Grecia, analizadas al azar, utilizando los instrumentos y metodología avalados por la CONAMI. Estudio comparativo de la tasa de mortalidad infantil en los 27 cantones de Costa Rica con más de 1000 nacimientos vivos por año. Resultados: Se estudiaron 35 muertes infantiles, correspondientes al 57..37% de las 61 muertes infantiles del cantón de Grecia en el período 1996 - 2000 . El 63 % de los recién nacidos eran del sexo femenino y 37 % del sexo masculino. En el 28.85 % de los hogares habían necesidades básicas insatisfechas ( N.B.I ) y 64.70 % de las madres solo tenían educación primaria, la cual era incompleta en el 20.58 % . Se calificaron como evitables el 40 % de las muertes infantiles. Las muertes en el período neonatal sumaron el 63 % de las muertes infantiles. De las 35 muertes analizadas, el 48.57 % fueron causadas por Malformaciones Congénitas y Anomalías Cromosómicas (ROO-R 99) y 37 % por Ciertas Afecciones del Período Perinatal ( POO-P96 ) , estas últimas tradicionalmente las más frecuentes. En un análisis de los 27 cantones del país, homologados por tener más de 1000 nacidos vivos por año, se constató que el cantón de Grecia tiene la más baja tasa de mortalidad infantil en el quinquenio 1996 - 2000 , y la misma es menor del 10 por 1000 nacidos vivos, específica mente igual al 9. 09 por mil nacidos vivos. Conclusiones: Se resalta el cambio en la estructura causal de la mortalidad infantil del cantón de Grecia, al ascender al primer lugar de causa de mortalidad infantil las Malformaciones Congénitas y Anomalías Cromosómicas y al ser desplazadas a un segundo lugar las Afecciones Perinatales , estructura causal propia de los países desarrollados. Esto en concordancia con el alcance de una tasa de mortalidad infantil menor del 10 %</p></abstract>

EI TAC de cerebro muestra ensanchamiento del tallo cerebral con hipodensidad izquierda. La resonancia magnética muestra una tumoración compleja del tallo cerebral afectando principalmente la protuberancia y pedúnculo cerebral izquierdo, así como caudalmente la parte alta de la médula oblongada con porción quística que ejerce compresión sobre el cuarto ventrículo sin producir hidrocefalia.Se le iniciará tratamiento radioterapéutico paliativo</p></abstract>

Se le determina una alteración en la cabeza del fémur izquierdo. La biopsia reveló un osteosarcoma. Es tratada con 6 ciclos de quimioterapia. Cuatro meses después se le realiza una cirugía de Van ness, requiriendo posteriormente una epifisiodesis de fémur distal y tibia proximal izquierda. Un año después reingresa por una masa pélvica izquierda. Se le realiza una biopsia que muestra recidiva tumoral. La masa se extendía hacia labios mayores y a glúteo izquierdo posterior. En sala de operaciones se le realiza una hemipelvectomia extrapélvica más colgajo cutáneo. La paciente evoluciona satisfactoriamente por lo que se egresa</p></abstract>
