Use of Amikacin in a hospital for children: microbiological and clinical studies.

Trends in relative susceptibility of clinical isolates, mostly from newborns with nosocomial infections, to the aminoglycosides in use in a hospital for children are described and related to practical therapeutic aspects. Currently, amikacin is the most effective of the available antibiotics against many gram-negative bacterial species, and its administration appears to be as complicated as that of other aminoglycosides. With 5 mug/ml taken as the cut-off point for susceptibility in vitro, 90% of 211 clinical isolates (Pseudomonas aeruginosa, Escherichia coli, Klebsiella, Serratia, and other species) could be considered sensitive to amikacin; the respective figures for sensitivity to sisomicin, gentamicin, and tobramycin were 80.5%, 66%, and 70%. Cross-resistance of microorganisms to amikacin and gentamicin, sisomicin, or tobramycin has not been demonstrated. Treatment with amikacin was successful in 13 of 15 children (premature and normal newborns with primarily septicemia); death of two patients was attributable to the underlying disease. For neonatal infections we recommend 12 mg of amikacin/kg per day; determination of the minimal inhibitory concentration for the causative pathogen and monitoring of serum concentrations are desirable.

[Relationship between the O2-affinity of the blood and erythropoiesis during the early months of life].

In 107 infants aged 3 hours to 9 months, hemoglobin concentration, 2,3-DPG concentration and GOT activity in red cells, and reticulocyte count were determined in order to evaluate whether the previously observed decrease in red cell 2,3-DPG [1] during the first 30-40 days of life related to red cell ageing. A significant positive correlation of 2,3-DPG vs. GOT, an indicator of red cell age, is found. The decrease in 2,3-DPG over a period of 25-30 days is finally followed by a sharp rise in reticulocyte count, suggesting that an alteration in blood oxygen affinity might trigger the onset of erythropoiesis in normal infants in this age group.

[HbM Erlangen: alpha2beta263(e7) tyr. New mutation with haemolysis and NADH-methaemoglobin reductase deficiency (author's transl)].

Report on a further hemoglobin M variant, discovered in a boy with congenital cyanosis. Chemical analysis of hemoglobin structure revealed indentity with HbM Saskatoon (= beta63 His leads to Tyr). The abnormal hemoglobin is characterized by normal oxygen transport function. The observed slight constant hemolysis is thought to be due to increased instability of the abnormal hemoglobin molecule. In addition to the hemoglobin anomaly, the activity of NADH-methemoglobin reductase was reduced by approximately 40% of normal. None of the parents presented with an abnormal hemoglobin, indicating that the occurrence of hemoglobin M Erlangen is most likely the result of a new mutation.
