Isolated supraclinoid occlusive disease of the internal carotid artery.

Isolated supraclinoid occlusive disease of the internal carotid artery is a rare cause of cerebral ischemia. The authors of the only review of this subject concluded that it is caused predominantly by factors other than atherosclerosis. We examined 6 patients with isolated supraclinoid occlusive lesions. Five of them had one or more risk factors for atherosclerosis. Thus, the isolated stenosis of that part of the internal carotid artery does not seem to represent a particular pathologic entity.

Nephrotoxicity induced by cancer chemotherapy with special emphasis on cisplatin toxicity.

Renal failure in cancer patients is a common problem in oncology; this complication is frequently multifactorial in origin. Several antineoplastic agents are potentially nephrotoxic; previous renal impairment as well as combinations with other nephrotoxic drugs may increase the risk of nephrotoxicity during administration of chemotherapy. Methotrexate-related renal damage most frequently occurs with high-dose therapy and can be avoided by forced alkaline diuresis and administration of folinic acid. Renal dysfunction secondary to semustine (CH3-CCNU) is clearly related to cumulative doses in excess to 1,200 mg/m2; the onset may be delayed and renal failure progress despite drug discontinuation. Streptozotocin is also nephrotoxic and may cause proteinuria and renal tubular acidosis; progressive renal failure can be predicted by a close monitoring of proteinuria and prevented by drug discontinuance. Mitomycin-associated renal failure frequently presents with signs of microangiopathic hemolytic anemia; renal failure is usually delayed but occasionally, it may be rapidly progressive despite drug discontinuance. Cisplatin nephrotoxicity is clearly dose-related and used to be considered dose limiting. Renal insufficiency can be prevented by hydration and forced diuresis; in addition, hyperhydration with mannitol-induced saline diuresis may allow administration of high doses and thus circumvent the dose-limiting effect of cisplatin-induced renal toxicity. Cisplatin-induced renal magnesium wasting occurs frequently and should be supplemented. Other approaches to reduce cisplatin nephrotoxicity are currently under investigation and are discussed.

[Progressive multifocal leukoencephalopathy in hemophilia A. Is there a relation to AIDS?].

Progressive multifocal leukencephalopathy (PML) due to Papovavirus is usually combined with a cellular immunodeficiency as a consequence either of a neoproliferative disease or of medical treatment. In the first description of a case of PML in combination with substituted hemophilia A with no known cellular immunodeficiency, possible pathogenetic relations to factor VIII substitution as well as to AIDS, caused by HTLV-III virus, are discussed.

HbSC hemoglobinopathy suspected by chest x-ray and red blood cell morphology.

Thorax scan was performed for elucidation of a pulmonary problem in a Nigerian immigrant. The aspect of the vertebrae suggested sickle cell disease, of course without specification of the genotype. Routine hematological tests seemed compatible with an HbSC disease, showing typical laboratory features, namely a significant proportion of hyperchromic RBC, corresponding to secondary, non hereditary spherocytosis, presence of numerous target cells and occasional HbC crystals on Pappenheim stained blood films. The diagnosis of HbSC disease was confirmed by HPLC, iso-electric focusing and citrate agar electrophoresis of hemoglobin and by reverse phase HPLC of globin-chains. This case illustrates the importance of screening for hemoglobin anomalies as it is performed in a multiethnic country such as the Grand Duchy of Luxembourg
