An amyloid protein that precipitates in the cerebral vessel walls of Dutch patients with hereditary cerebral hemorrhage with amyloidosis is similar to the amyloid protein in vessel walls and senile plaques in brains of patients with Alzheimer's disease, Down syndrome, and sporadic cerebral amyloid angiopathy. Cloning and sequencing of the two exons that(More)
Lewit and Sereghy (1975) have expressed some doubts about the existence of the dorsal plica mediana and its relation to the median translucency regularly seen on peridurographic pictures made in the PA projection. The present paper reports the demonstration of the dorsal plica mediana in fresh anatomical preparations under conditions lowering the intradural(More)
After the first description by Paget (1854) and later on by Mohr (1890) and Schultze (1892), more than 100 years have passed by before it was generally recognized that compression of the median nerve in the carpal tunnel could be related to the majority of cases with nocturnal acroparaesthesiae in the hand and fingers. A short survey is given on 914(More)
Clinical and neuropathological findings are reported in 63 patients with hereditary cerebral haemorrhage with amyloid angiopathy. Patients had mostly recurrent strokes, and at least 80% of these were haemorrhages. Almost a third of the patients died within a year of their first and only recorded haemorrhage, half of them within two weeks. This angiopathy(More)
The authors report a case of homozygous thalassemia in which a mass of hematopoietic tissue in the vertebral canal caused spastic paraparesis. Surgical removal of the tissue plus radiotherapy were successful. The pathological findings indicated direct extension of hematopoietic tissue from the adjacent bone marrow into the epidural space of the vertebral(More)
This article describes 136 patients with hereditary cerebral haemorrhages; all patients belonged to families (originally) resident in Katwijk (The Netherlands). Cases of hereditary cerebral haemorrhage have also been reported in NW-Iceland, and in the Dutch coastal village of Scheveningen. Katwijk is a Dutch fishing-village, located 20 miles north of(More)
A case of involvement of the spinal cord by schistosoma masoni is described. There was a granuloma in the conus medullaris stimulating an intramedullary tumor. Biopsy led to the correct diagnosis. After decompression of the spinal cord and the oral administration of Niridazole (Ambilhar) the patient recovered satisfactorily.
Cerebral amyloid angiopathy (CAA) refers to a group of hereditary (hereditary cerebral hemorrhage with amyloidosis, HCHWA and sporadic (SCAA) disorders characterized by amyloid fibril deposition restricted to the leptomeningeal and cortical vasculature leading to recurrent hemorrhagic and/or ischemic accidents. On clinical and biochemical grounds, two forms(More)
