A rare case of aplastic anemia which was considered to be induced by allopurinol was reported. A 48-year-old female had suffered from urolithiasis and chronic renal insufficiency. She was administered allopurinol for hyperuricemia for 4 months, and subsequently developed severe pancytopenia and bone marrow suppression. After stopping of allopurinol administration, she was administered prednisolone but died of gastro-intestinal tract bleeding and sepsis on the 21th hospital day, without hematological recovery.

Over a period of nine years we observed 52 children with acute neurological symptoms which were caused by a cerebrovascular disease. Fourteen patients had congenital vascular malformations, most frequently AV-angiomas (9 patients). A Sturge-Weber-Syndrome and a venous angioma were found in two cases and one patient had an aneurysm of the middle cerebral artery. Thirty-eight patients had acquired cerebrovascular diseases such as ischaemic infarctions (22), intracranial haemorrhages without vascular malformations (14) and thromboses of the dural sinus (2). The cerebral infraction was a complication of a congenital heart disease in 8 children, two others suffered from chronic renal insufficiency and were on haemodialysis. Two children had a trauma of the internal carotid artery and in one patient a large haemorrhagic infarct was caused by hypernatremic dehydration. In 9 patients (6 females, 3 males) no obvious aetiology of the infarct could be found. However, in most of these cases a nonspecific febrile illness preceded the neurological manifestations. The thrombosis of the dural sinus occurred in a 6-week old previously healthy infant and in a 3-year old boy as a complication of a nephrotic syndrome. Intracranial haemorrhages (without cerebrovascular malformations) occurred in 14 patients, mainly as a complication of haematological diseases (acute lymphatic leukaemia, severe aplastic anaemia, haemophilia A, lupus erythematodes). Four children had spontaneous intracerebral haemorrhages without obvious causes. The prognosis for survival was good in children with infarcts, but persisting neurological deficits were more severe than in children with haemorrhages. At the acute stage the lethality was higher in children with intracranial haemorrhages.

Humoral regulation of erythropoiesis has been known for 100 years, while clinical utilization of recombinant human erythropoietin (rhEPO) only for two decades. It can be said that there is much experience in regard to indications, models and results of its clinical utilization. According to the standpoint of secretion of erythropoietin, anemias can be divided into those where secretion is increased and satisfactory, those where it is increased but not satisfactory and into those where it is not increased or it is even decreased. Anemias of the first group are not an indication for rhEPO utilization, the second group is relative and the third group absolute indication for its utilization. The best results are achieved with absolute indications and it is anemia in chronic renal insufficiency and nonphysiologic anemia of premature babies. Good results can be expected, but not predicted in relative indications, such as anemias in chronic infections, anemias in malignant diseases, myelodysplastic syndrome, aplastic anemia and other secondary anemias. Utilization of rhEPO is useful also in certain states without anemia, especially in transfusiology.
