Résumé

Se ha medido la dosis en la superficie de entrada de ojos, tiroides y gónadas en pacientes sometidos a estudio de radiografía de tele de tórax mediante dosimetría termoluminiscente. Se usaron 5 dosímetros en cada una de las exploraciones; encontrándose los siguientes rangos de dosis: 20 mGy a 350 mGy. En el caso de los pacientes pediátricos se propone incluir la información de las dosis recibidas en su cartilla de vacunación con el fin de hacer un seguimiento de los posibles efectos nocivos en su salud.


Doses have been measured at the entrance surface of eyes, thyroid and gonads in patients undergoing chest x-ray studies, using thermo-luminiscent dosimetry. Five dosimeters were used in each investigation, and doses ranged from 20 mGy to 350 mGy. In the case of pediatric patients, it is proposed that dose information from diagnostic examinations is included in the vaccination chart in order to correlate with findings at follow-up.

Résumé

Neutropenia exists when the neutrophil counts is less than 1000/mm3 in infants between 2 weeks and 1 year of age and less than 1500/mm3 beyond 1 year of age (1). Severe infections occur when the absolute neutrophil count is below 500/mm3 with perirectal abscesses, pneumonia, and sepsis being common. Granulocyte Colony-Stimulating Factor (G-CSF) produces a sustained neutrophil recovery in patients with severe neutropenia, reduces the incidence and severity of infection, and improves the quality of life. Various cytopenias, including neutropenia, thrombocytopenia and pancytopenia, have been reported in association with inborn errors of branched aminoacid metabolism such as methylmalonic, propionic and isovaleric acidemia. We report an infant with methylmalonic acidemia who presented severe neutropenia
