The authors have updated a series of 166 prospectively followed unoperated symptomatic patients with arteriovenous malformations (AVM's) of the brain. Follow-up data were obtained for 160 (96%) of the original population, with a mean follow-up period of 23.7 years. The rate of major rebleeding was 4.0% per year, and the mortality rate was 1.0% per year. At(More)
U.S. stocks have been shown to earn higher returns during earnings announcement months than during non-announcement months. We document that this earnings announcement premium exists across the globe. Moreover, it is not isolated to a few countries. Of the 20 countries with enough data to conduct a within-country analysis, nine exhibit a significantly(More)
From June, 1982, through June, 1985, 113 patients were evacuated to Rambam Maimonides Medical Center with penetrating craniocerebral injuries sustained in ongoing military hostilities in Lebanon. Two factors distinguished this group of patients from those presenting in earlier conflicts: 1) this was the first large series in which computerized tomography(More)
OBJECTIVE To investigate the rate of testosterone recovery and changes in bone mineral density in patients found to be osteoporotic while receiving luteinizing hormone-releasing hormone (LHRH) analogues after changing to antiandrogen monotherapy in an attempt to reduce further demineralization. PATIENTS AND METHODS Fifteen patients receiving LHRH analogue(More)
This paper studies the capital market consequences of unique and unexpected mandatory disclosures of banks’ liquidity and the resulting changes in banks’ behavior. I employ a hand-collected sample of the disclosures of banks’ borrowing from the US Federal Reserve Discount Window (DW) during the financial crisis. I find that these disclosures contain(More)
Multiple myeloma is the malignant proliferation of plasma cells involving more than 10 percent of the bone marrow. The multiple myeloma cell produces monoclonal immunoglobulins that may be identified on serum or urine protein electrophoresis. Bone pain related to multiple lytic lesions is the most common clinical presentation. However, up to 30 percent of(More)
Large arteriovenous malformations of the jaws are relatively rare, potentially life-threatening lesions. When the lesion is not suspected, extraction of teeth can be fatal. The occurrence and treatment of arteriovenous vascular communications in the head and neck region have traditionally presented most perplexing problems. Traditional treatment has usually(More)
The major diagnostic features of Ellis van Creveld syndrome (EvC) includes disproportionate short stature, polydactyly, ectodermal anomalies, and structural heart defects. We describe three siblings with EvC of a non-consanguineous mating. The history of these siblings well illustrate the clinical manifestations and complications that children with EvC(More)
Although facilities at many civilian centers far exceed those historically available to military neurosurgeons in the field, the principles derived from combat injuries continue to apply. It is hoped that there may be differences in salvageability at the margin owing to the availability of more sophisticated imaging and critical care monitoring techniques,(More)
Perfusion of absolute ethyl alcohol into the middle cerebral artery of six rhesus monkeys was performed using the Pevsner miniballoon catheter system. The animals were sacrificed by thoracotomy and intracardiac perfusion of a mixed aldehyde solution for fixation. Preliminary angiography and electron microscopy suggest absolute ethyl alcohol is a good(More)
