In order to evaluate the sensitivity and specificity of magnetic resonance angiography (MRA) in spontaneous subarachnoid haemorrhage, 14 patients with recent haemorrhage verified by CT or lumbar puncture were investigated with both selective intra-arterial digital subtraction angiography (IA-DSA) and MRA by two independent teams, each having the same(More)
A detailed introduction to published analogue circuit design techniques using Si and Si/SiGe FET devices for very low power applications is presented in this review. The topics discussed include subthreshold operation in FET devices, micro-current-mirrors and cascode techniques, voltage level-shifting and class-AB operation, the bulk-drive approach, the(More)
Localisation of spinal cord lesions by MRI was correlated with neurological symptoms and signs in 16 patients with clinical and laboratory evidence of multiple sclerosis. There was good correspondence between spinal cord lesions and motor tract signs. On the other hand, superficial or deep sensory disturbances correlated with spinal cord lesions in only(More)
8 thalassaemic patients with complications due to pressure by heterotopic marrow on the spinal cord, the vertebral column, or the airways were given radiotherapy. Small doses of radiotherapy (10 to 26 Gy) relieved symptoms in all of them. 3 of the patients were followed-up radiographically. In 2 the mass of heterotopic marrow regressed completely and in the(More)
Two cases of extramedullary hemopoiesis in the lower spinal column are reported. One of them was due to thalassemia major and the other to thalassemia intermedia. CT and MRI studies showed paraspinal and presacral masses respectively which caused nerve root compression. It is concluded that the differential diagnosis of low back pain and radicular or(More)
INTRODUCTION Duodenal stump disruption remains one of the most dreadful postgastrectomy complications, posing an overwhelming therapeutic challenge. PRESENTATION OF CASE The present report describes the extremely rare occurrence of a delayed duodenal stump disruption following total gastrectomy with Roux-en-Y esophagojejunostomy for cancer, because of(More)
INTRODUCTION Biliary inflammatory pseudotumors (IPTs) represent an exceptional benign cause of obstructive jaundice. These lesions are often mistaken for cholangiocarcinomas and are treated with major resections, because their final diagnosis can be achieved only after formal pathological examination of the resected specimen. Consequently, biliary IPTs are(More)
