[EX Q]: Abstract: Tuberculous aortitis is a rare entity and its association with necrosis and perforation is even more unusual. Our pulmonary medicine service originally evaluated an elderly woman with a right pleural effusion and upper lobe infiltrate thought to be tuberculosis. An abdominal CT scan performed at that time showed extensive periaortic adenopathy. Isoniazid and rifampin were started, but both were stopped by the patient after less than 6 months of therapy. The patient later had night sweats, a left pleural effusion, and a tender abdominal mass thought to be a symptomatic aneurysm. At operation, the aorta was necrotic and had an inflammatory mass and perforation on the left side. Infrarenal aortic ligation and resection were performed to control infection. A previously placed axillofemoral graft obviated the need for concomitant revascularization. The patient was treated postoperatively with isoniazid and rifampin until hyperbilirubinemia developed, which necessitated alternate therapy with ethambutol and streptomycin. The patient died one month after operation of a presumed pulmonary embolus.

[EX Q]: Abstract: Previous research on visuospatial function in Parkinson's disease is reviewed. The present experiment was designed to test two fundamental aspects of spatial ability, namely right-left discrimination and the manipulation of those concepts in different spatial perspectives. Measures of accuracy and reaction time were taken. The performance of patients with Parkinson's disease did not differ from that of normal subjects in the spatial components of the task. Neither a review of the literature, nor the results of the present study, give support to the idea of a generalized visuospatial deficit in Parkinson's disease.

[EX Q]: Abstract: During a 5-year period, 15 cases of primary gastrointestinal lymphoma, corresponding to 14% of the non-Hodgkin's lymphomas, were diagnosed in a population of 200,000. Most patients had a short duration of symptoms--less than 3 months--and a clinical picture dominated by abdominal pain. All patients were laparotomized and six patients presented with an acute abdomen and were subjected to emergency operations. In seven cases, gastrointestinal malignancy was not suspected preoperatively. The patients were treated with a combination of surgery, cytostatic therapy, and/or radiotherapy. Cases with localized disease had a favorable prognosis, seven of nine patients being alive 31 to 70 months after diagnosis. A statistically significant difference in median survival was also noted between patients with lymphomas of low-grade and high-grade malignancy (70+ vs. 10.5 months).
