Intracanalicular arachnoid cyst mimicking acoustic neuroma: CT and MRI.

A patient with a surgically proven intracanalicular arachnoid cyst was studied using computed tomography, magnetic resonance imaging, and air CT cisternography. The lesion had a similar radiographic appearance to acoustic neuroma and therefore, although rare, must be considered in the differential diagnosis of intracanalicular mass lesions. We report a case in which examination was performed, in evaluating the lesion, utilizing high-resolution air CT cisternography and magnetic resonance imaging (MRI).     

Sex differences in pattern of drinking.

Drinking patterns of male and female Long-Evans rats were compared during a 15-day drinking period. All animals were tested for preference for alcohol for 24 h during which food, water, and beer containing 5% ethanol were freely available. Animals drinking 50 ml or more of beer were chosen for the experiments. On days 1-5, animals were offered food, water, and beer containing 5% ethanol (v/v). On days 6-15, the concentration of ethanol in the beer was doubled to 10% (v/v). Preference ratios (beer/total fluid) were higher for females than males, and females consumed more grams of alcohol per unit of body weight. When alcohol concentration was doubled, females increased alcohol intake (g/kg), while males tended to titrate alcohol intake to levels consumed at 5% concentration. Female patterns of drinking differed from male patterns of drinking.     

Changes in marital and sexual functioning in long-term survivors and their spouses: Testicular cancer versus hodgkin's disease

This study compares the effects of the cancer experience on various aspects of marital and sexual functioning (e.g., communication, emotional support, body image, sexual satisfaction and frequency) for two groups of long-term cancer survivors (testicular cancer and Hodgkin's disease) and their spouses. Comparisons between the two patient groups showed significantly more survivors of Hodgkin's disease than testicular cancer reporting the emergence of special issues and changes in the marital relationship. No differences emerged between the spouse groups on sexual functioning variables; however, spouses of survivors of Hodgkin's disease were more likely than spouses of survivors of testicular cancer to report the development of special issues and communication difficulties. A substantial proportion of both survivor groups disclosed negative changes in body image and sexual frequency. Majorities of both survivors and spouses acknowledged that the illness had drawn them closer together. When representative marital/sexual functioning variables were used to predict Family Environment Scale (FES) scores for survivors and for spouses, changes in the spouse's importance, influence of the illness on the relationship, and changes in sexual frequency emerged as significant predictors. The clinical significance of long-term changes in marital and sexual functioning for the couple and the need for therapeutic interventions are discussed.     

Renal transplant obstruction by B cell lymphoproliferative disorder: case report and review of the literature

We report a case of renal transplant ureteral obstruction caused by a cyclosporine-associated B cell lymphoproliferative disorder. The interaction of cyclosporine with Epstein-Barr virus infections and the predisposition towards B cell lymphoproliferative disorders are reviewed. The characterization of these tumors by deoxyribonucleic acid hybridization studies and a review of the clinical experience treating these disorders also are presented.
