ABSTRACT
Hematological parameters and free eythrocyte protoporphyrin (FEP) on a capillary blood sample were measured in 175 apparently healthy children ranging from 6 months to six years of age. Thirty eight children had hematological parameters descended and/or FEP elevated were asked to return for blood counts, FEP, serum ferritin, serum iron, total iron binding, capacity, transferrin saturation and ALA-D activity, on a venous blood sample. Only 34 children returned. Twenty seven, 15.4%, had iron stores descended or iron deficiency, 18 of them with anemia. FEP had significant correlation coefficients with hematologic parameters (p less than 0.001), serum iron and transferrin saturation (p less than 0.01). On iron deficiency anemia detection, the FEP had a sensibility and specificity of 0.94 and 0.75 respectively.

Se comunica el caso de una enferma de 19 anos con telangiectasia hemorragica hereditaria acompanada de fistula arteriovenosa pulmonar macroscopica unica del lobulo superior derecho, con suplemento arterial proveniente de la circulacion pulmonar y drenaje anormal de las venas del lobulo medio en la vena pulmonar inferior.Se identificaron cinco pacientes conseguineos con epistaxis (dos fallecidos a consecuencia de ellas); los tres vivos tenian telangiectasias en piel y mucosas y ninguno fistula arteriovenosa pulmonar. Los estudios para identificar sindrome de coagulacion intravascular y enfermedad de Von Willebrand acompanantes fueron negativos.La reseccion del lobulo superior derecho fue seguida por desaparicion de las manifestaciones clinicas y normalizacion de las pruebas de la funcion pulmonar
