Normative data of hemoglobin concentration and free erythrocyte protoporphyrin in a private pediatric practice: a 1990 update.

Free erythrocyte protoporphyrin (FEP) and hemoglobin (Hgb) concentrations were tested in 790 children in a private pediatric office; results were compared to those obtained in 1984. Only 16 children (2%) had abnormal FEPs in 1990 compared to 76 children (9.6%) in the earlier study. The mean FEP in the normal group also decreased significantly in each age group studied. The hemoglobin concentrations were not significantly different in most of the age groups studied. Screening for iron deficiency in our pediatric practice by determining hemoglobin and FEP concentrations had a much lower yield in 1990 than in 1984.

Alternatives to total splenectomy: two case reports.

Postsplenectomy sepsis is a serious problem with high morbidity and high mortality. Surgical alternatives to total splenectomy are being sought. This paper describes two cases where, after splenectomy, some splenic tissue was either reimplanted or was left in situ and remains functional.

Congential dyserythropoietic anemia--type IV.

Congenital dyserythropoietic anemia is characterized by ineffective erythropoiesis and increased numbers of multinucleated red cell precursors in the marrow. This syndrome has been subclassified on the basis of morphologic differences in the red cell precursors. Type I is characterized by megaloblastoid erythropoiesis and macrocytosis; Type II, by normoblastic multinuclearity and normocytosis; and Type III, by frequent giant multinucleated erythroblasts and macrocytes. Type II is further distinguished from the other types by serologic and ultrastructural abnormalities. The patient presented in this report does not fit any of the above categories; her red cells are similar to Type II congenital dyserythropoietic anemia cells, but no characteristic ultrastructural or serologic abnormalities are present. It is suggested that this patient may represent an additional variant of congenital dyserythropoietic anemia, Type IV.
