A baby girl, born prematurely and with Down's syndrome, is hospitalized at the age of 51 days for a megaloblastic anemia. The anemia was caused by a selective malabsorption of vitamin B12 (Imerslund's syndrome), even in presence of intrinsic factor. The pathogenesis of different causes of vitamin B12 deficiency is discussed and the favourable development of this case after four years of treatment is shown.

Glycolytic activity was measured in red cells from epileptic patients treated with anticonvulsant drugs. These results are compared with measurements of red cell glycolytic activity from megaloblastic anaemia patients and normal controls. The differences obtained between epileptic patients and controls, as well as the differences between anaemia, epileptic patients and controls is discussed.

A patient with hepatocellular carcinoma, megaloblastic anaemia and increased concentration of serum cobalamin is described. Plasma TC I was increased to 10,000 times the normal concentration, thus explaining the increased concentration of serum cobalamin and a false Schilling test. The increase in plasma TC I in concurrence with undetectable amounts of plasma TC II was a likely explanation for the anaemia. The electron microscopic picture of the hepatocellular carcinoma was in accordance with TC I being produced by the tumour cells.

Anemia is the most commonly haematologic disorder observed in Crohn's disease. Secondary megaloblastic anemia related to a nutritional deficiency of vitamin B 12 and/or folic acid is a rare condition as well as auto-immune haemolytic anemia. Iron lack microcytic hypochromic anemia is far more frequent. It is probably due to several causes as microscopic or macroscopic haemorrhages, inflammatory syndrome, disturbance of iron absorption. Hyperleucocytis, hypereosinophilia, hypoprothrombinemia related to the inflammatory syndrome and/or lesions of the bowels are frequently observed in such patients. Anyhow, heamatologic disorders seem markedly correlated with the activity of the disease and should be useful in the follow up patients with Crohn's disease.

In two separate trials, 140 cases of Pregnancy Anaemia were investigated in the University Teaching Hospital, Lusaka. The distribution of anaemia was as follows: Iron deficiency 118 (84.2%); dual deficiency 15 (19.7%); haemolytic five (35%); and megaloblastic 2 (1.4%). Anaemia with megaloblastic change was more common in the second study.

Using a method involving elution of hemoglobin bands from cellulose acetate strips following electrophoresis of hemolysates, hemoglobin A2 (Ab A2) was quantitated in bloods from 300 healthy individuals and 904 patients. The percentage of Hb A2 was elevated in beta-thalassemia heterozygotes and some patients who had megaloblastic anemia. In the latter, the highest Hb A2 levels were observed in patients with the most severe anemia. Low Hb A2 percentages were found in iron-deficiency anemia, hereditary persistance of fetal hemoglobin, and Hb H disease. In iron-deficiency anemia, the lowest levels of Hb A2 were observed in association with the most severe anemia. Iron and folate deficiency each suppressed Hb A2 levels in beta-thalassemia heterozygotes; however, vitamin B12 deficiency did not alter the percentage of Hb A2 in thalassemia. Malignant tumors, renal and hepatic insufficiency, chronic infections and inflammation, hemolytic disease, lead poisoning, aplastic anemia, leukemia, myelofibrosis, and hypothyroidism did not change Hb A2 levels. The pathogenesis of altered Hb A2 levels and their clinical significance in various diseases are discussed.

Exfoliative cytology smears from the buccal mucosa of patients with sickle-cell anemia, selected controls, and patients with other diagnosed anemias were studied for nuclear aberrations. A filar micrometer eyepiece was used to count the number of nuclei larger than 14 microns in mean diameter in a 500 cell count on each slide. Use of the Scheffe method of paired comparisons, disclosed that the number of cells larger than 14 microns in mean diameter, was significantly smaller in the control subjects, patients with microcytic anemia, and subjects with sickle-cell anemia than in the patients with megaloblastic anemia. Serum folate-deficient subjects had significantly more nuclei, per 500 cells, larger than 14 microns than control subjects or subjects on folate therapy. An explanation for the enlarged nuclei in smears from sickle-cell anemia patients is given. The possible use of this counting procedure to evaluate tissue folate status is suggested.

A retrospective survey of 700 marrow examinations in Papua New Guinea in a 2 1/2 year period has been carried out. Over half of the total came from the Port Moresby General Hospital. Anaemia and splenomegaly were the commonest indications. A disturbing proportion of the specimens were unsatisfactory for interpretation. Hypercellular marrows with erythroid hyperplasia were very common. Iron stores were absent or nearly absent in almost half of the evaluable specimens; this proportion rose to over 95% amongst pregnant or post-partum women with anaemia. Other relatively frequent findings included: a combination of features consistent with hypersplenism; mild degrees of eosinophilia and/or plasmacytosis; and mild degrees of megaloblastic changes. Haematological malignancies were found in over 10% of evaluable specimens. Of 611 assessable marrows from Melanesians, only 11 (1.8%) were entirely normal, but another 151 (24.7%) contained only minor abnormalities.

A 9 1/2-year-old boy who had been treated with pyrimethamine and sulphadimidine presented with generalised lymphadenopathy, fever, and an unusual sun-tanning. He was found to have mild anaemia, severe leucopenia and thrombocytopenia. The bone marrow was megaloblastic. Lymph node biopsy was initially interpreted as showing malignant lymphoma. No treatment for neoplasia was given and he was well 4 1/2 years later. We consider that the seemingly malignant changes were due to pyrimethamine.
