Although meningioma is typically a benign tumor, in rare instances, it metastasizes. The current case example exhibits moderately increased metabolism despite findings of high-grade malignancy on biopsy.

Congenital pulmonary artery (PA) stenosis is a rare congenital heart defect. In most cases there is an antecedent history of maternal rubel1a.r Acquired PA stenosis results from compression and narrowing of 21 major PAS by an extrinsic process. Acquired PA stenosis is most often the result of a benign or malignant thoracic

Management strategies for suspected temporal arteritis range from bilateral temporal artery biopsy to empiric corticosteroid therapy. A decision analysis of the clinical situation was constructed, and a sensitivity analysis for varying prevalences of temporal arteritis was used to calculate costs for different management strategies. Conclusions suggested by the analysis include the following: (1) due to the high cost of blindness, suspicion of disease must be low (less than 1.4%) not to biopsy; (2) at high suspicion of disease (greater than 30%), empiric steroids are the cheapest management; (3) when diagnostic procedures are indicated, bilateral biopsy is the cheapest initial diagnostic procedure; and (4) if unilateral biopsy is negative, a second biopsy is always cost effective.

Many persons, including physicians, regard a "normal" bowel habit as being at least one bowel movement per day. In truth, the spectrum of normal covers anywhere from three movements per day to three or even less per week. This article outlines aspects of the history that will be most helpful in determining if constipation is indeed present. It also provides very useful information on the mechanisms of laxative action.
