Smoking and bone mineral density: comprehensive analyses of the third National Health and Nutrition Examination Survey (NHANES III).

Unlabelled: Some questions remain on the relationship between smoking and bone health. Detailed analyses of the relationship between smoking and BMD are presented, essentially ruling out non-linear associations as an explanation for inconsistent results in the literature.

Introduction: To provide comprehensive multiple regression and dose-response analyses of the association between smoking behavior variables and bone health as assessed by radiologically determined bone mineral density in NHANES III.

Pre-operative intracranial meningioma embolization.

Pre-operative embolization is a routinely utilized therapeutic adjunct to the resection of hypervascular lesions of the head and neck. In particular, pre-operative cerebral angiography and tumor embolization has become standard practice at many centers in the management of select intracranial meningiomas. However, controversy remains regarding its specific indications and clinical utility.

Training in endovascular surgical neuroradiology.

Background: During the past few years, the field of endovascular surgical neuroradiology has been expanding. Neurosurgeons, radiologists, and neurologists are currently being trained. We analyzed data from a national survey of endovascular training programs to assess the current training status and future projections.

Radiation exposure of the anesthesiologist in the neurointerventional suite.

Background: Scatter radiation during interventional radiology procedures can produce cataracts in participating medical personnel. Standard safety equipment for the radiologist includes eye protection. The typical configuration of fluoroscopy equipment directs radiation scatter away from the radiologist and toward the anesthesiologist.

Update on the natural history of intracranial atherosclerotic disease: A critical review.

Intracranial atherosclerotic disease (ICAD) contributes to a significant number of ischemic strokes. There is debate in the recent literature concerning the impact of the location of stenosis in ICAD on outcome. Some reports have suggested that disease processes and outcomes vary by vessel location, potentially altering the natural history and indications for intervention.
