Statistical Mediators of the Association Between Mindfulness and Sexual Experiences in Men with Impaired Sexual Function.

Mindfulness-based therapy has shown promise as a treatment for female sexual dysfunction and has the potential to be an efficacious treatment for male sexual dysfunction. However, there has been little empirical evidence regarding the mechanisms through which mindfulness may improve sexual experiences, especially for men. Recent theoretical reviews have suggested potential mediators that may explain the beneficial effects of mindfulness on symptoms of male sexual dysfunction, including reduced avoidance of sex, reduced distraction during sex, and/or reduced activation of negative sexual schemas. We attempted an initial statistical test of these factors as potential mediators of the association between trait mindfulness and multiple sexual outcomes (sexual function, sexual satisfaction, and sexual distress) using a cross-sectional correlational design. A total of 163 men with self-reported current impairments in one or more aspects of sexual function completed self-report scales using a secure online survey. Bivariate correlations indicated that mindfulness was significantly associated with sexual satisfaction, sexual distress, and premature ejaculation, but not other aspects of sexual function. Sexual avoidance statistically mediated the link between mindfulness and sexual satisfaction, both distraction and activation of negative schemas statistically mediated the link between mindfulness and premature ejaculation, and all three factors statistically mediated the link between mindfulness and sexual distress. These results generally supported previous theoretical work and have implications for future treatment outcome research.

Synchronous colonic adenocarcinoma and pelvic schwannoma.

Pelvic schwannomas are rare; it is even more rare for a pelvic schwannoma to occur concurrently with a colon cancer. The authors report the case of a 62-year-old woman with a cecal mass that was surgically removed and the histopathologic diagnosis was adenocarcinoma of the colon. Meanwhile, aretroperitonealpelvic nodalmasswas detected as questionable metastasis of the primary tumor. A subsequent computed tomography-guided fine-needle biopsy was carried out to establish the tumor stage. Surprisingly, the fine-needle biopsy revealed a benign schwannoma. This unusual case posed a dilemma in postoperative staging of the colon cancer.

Early surgical intervention for fulminant pseudomembranous colitis.

The objective of this study of a retrospective case series was to determine factors associated with survival after surgical intervention in pseudomembranous colitis (PMC). The study was conducted at a tertiary care medical center and comprised 36 patients who underwent colectomy for fulminant PMC from 1995 to 2006. Patients including 21 females ranged from 40 to 89 years of age (mean, 70 years). Comorbidities included diabetes (39%), cardiovascular disease (77%), chronic obstructive pulmonary disease (47%), and intake of immunosuppressive medications (45%). Seventy-two per cent received antibiotics in the previous 2 months. Only patients with a confirmation of PMC on pathology specimens were included in the study. All patients underwent colectomy. Patients were stratified into two groups: survivors and nonsurvivors. Various clinical factors/ parameters used in the management of patients with PMC were studied in these two groups. Survival was correlated with mean white blood cell count (23,000 survivors versus 40,000 nonsurvivors, P < 0.01); multisystem organ failure (16 per cent survivors versus 47 per cent nonsurvivors, P < 0.05); and preoperative pressors (16 per cent survivors versus 47 per cent nonsurvivors, P < 0.05). Overall mortality for the study period was 47 per cent. Mortality rate analysis revealed a lower rate for the more recent years (32 per cent for 2000 to 2006 versus 65 per cent for 1995 to 1999, P < 0.05). In the more recent years, the time elapsing before colectomy was also lower (1.4 days versus 2.5 days, nonsignificant), and patients had less preoperative hemodynamic instability (70 per cent versus 31 per cent, P < 0.03). In one institution, survival after surgery for PMC was found to be associated with a mean white blood cell count (< 37,000), nondependence on preoperative vasopressors, and surgical intervention before the onset of hemodynamic instability.
