BACKGROUND Strokes are an important cause of morbidity and mortality in young adults. However, in most cases the cause of the stroke remains unclear. Anderson-Fabry disease is an X-linked recessive lysosomal storage disease resulting from deficient alpha-galactosidase and causes an endothelial vasculopathy followed by cerebral ischaemia. To determine the(More)
Within Niemann-Pick diseases, type C has now been demonstrated to be a nosological entity totally distinct from types A and B, and is best characterized at present by unique abnormalities of intracellular translocation of exogenous cholesterol, which are briefly reviewed. Although the primary defect is still unknown in type C Niemann-Pick disease, this(More)
One postnatal and one prenatal case (same family) of a neurovisceral lipidosis compatible with a diagnosis of Niemann-Pick disease type C were studied. The postnatal case, aged 4 and 6/12 at death, was characterized morphologically (foamy cells in the bone marrow; storage histiocytes in rectal submucosa and extraneural viscera and ballooned neurons, the two(More)
The bone marrow cytological storage phenomena in generalized lysosomal lipid storage disorders (Gaucher disease, Niemann-Pick disease, GM1-gangliosidosis, cholesterol ester storage diseases) are reviewed. The value of bone marrow cytology as a pre-screening method in the diagnostic strategy for the different diseases depends on the disease type suspected(More)
Invasion of human mucosal cells by N. gonorrhoeae via the binding to heparansulfate proteoglycan receptors is considered a crucial event of the infection. Using different human epithelial cells and primary fibroblasts, we show here an activation of the phosphatidylcholine-specific phospholipase C (PC-PLC) and acidic sphingomyelinase (ASM) by N. gonorrhoeae,(More)
Through a survey of all departments of pediatrics, neurology and neuropathology in Germany, we calculated the incidence of all major forms of leukodystrophy. Only diagnoses based on specific biochemical tests in association with typical findings and/or neuroradiologically proven white matter involvement were accepted. In accordance with these strict(More)
Very low levels of arylsulfatase A (ASA) have been found in the leukocytes of healthy members of a metachromatic leukodystrophy (MLD) family. The cerebroside sulfate sulfatase (CSS) activities in the same individuals are about 10% of the control level. Arguments favoring a dominant mutation different from that of classical MLD are presented. This report(More)
Fabry's disease was diagnosed in an adult patient as a lipid storage-induced non-obstructive hypertrophic cardiomyopathy. Stable angina pectoris started 15 years before death, was followed by slowly progressive heart failure and repeated pulmonary thromboembolism with death at 63 years. Autopsy disclosed enormous cardiomegaly (1100 g), cardiac storage of(More)
Two male patients, aged 6 and 25, both with normal intelligence and absence of neurological abnormalities, exhibited dysostosis multiplex, dwarfism, odontoid anomalies, cloudy corneas, exessive excretion of keratan sulfate, and abnormal urinary oligosaccharides. Leukocytes and fibroblasts of both patients were deficient in acid beta-galactosidase (beta-gal)(More)
