Abstract: A study was undertaken to determine the effect of gender on criteria for the quantitative analysis of exercise-redistribution 201Tl myocardial scintigraphy. The studies of 26 normal females and 23 normal males were subjected to bilinear interpolative background subtraction and horizontal profile analysis. Significant sexual differences were found in both regional uptake ratios and washout rates. These differences primarily reflected a proportionately decreased anterior and upper septal uptake in females, and faster washout in females. Faster myocardial 201Tl washout rates in females could not be clearly ascribed to either a physiological or artifactual explanation. It is concluded that since important differences exist between males and females in the detected pattern of 201Tl myocardial uptake and washout, sex-specific criteria may enhance the predictive accuracy of exercise-redistribution 201Tl myocardial scintigraphy.

Abstract: A prospective clinical trial was conducted to estimate the rise in serum glucose level after an intravenous bolus of 50 ml of 50% dextrose solution (D-50) in the emergency department setting. Fifty one subjects with altered levels of consciousness were studied. Of these, 23 patients were known diabetics, and 28 were not diabetic. The change in glucose level for the total study group ranged from a low of 37 mg/dl to a high of 370 mg/dl, with a mean of 166 +/- 77 mg/dl. The mean for the diabetic and non-diabetic groups were 177 +/- 80 mg/dl and 154 +/- 75 mg/dl. These results suggest that serum glucose levels cannot be quantitatively predicted after a single intravenous bolus of D-50.

Abstract: Head and neck cancer has rarely been reported to be a cause of meningeal carcinomatosis. These tumors are known more for their local invasiveness rather than distant metastasis. This would appear to preclude meningeal involvement, but close proximity to multiple cranial nerves may provide an access to the meninges. Six cases of head and neck cancer with meningeal invasion are presented. All six cases had malignant cells in their cerebrospinal fluid. Three cases had malignant cells recovered from a ventricular specimen after lumbar punctures were negative. The most common clinical finding on presentation was cranial nerve involvement. The optic nerve was involved most often with nerves VI and V the next most frequent. Headache was present in four patients and seizures occurred in two. No patient had meningismus. Our current treatment plan involves insertion of an Ommaya Reservoir and intraventricular methotrexate. Only patients whose primary head and neck tumor shows a response to systemic therapy undergo Ommaya placement. Meningeal carcinomatosis in head and neck cancer may be more prevalent than previously thought and the likely mechanism is via direct extension rather than hematogenous spread.
