Parasitic stool testing in newly arrived refugees in Calgary, Alta.

OBJECTIVE: To determine the prevalence of intestinal parasites and rates of stool testing compliance, as well as associated patient characteristics, among newly arrived refugees at the Mosaic Refugee Health Clinic in Calgary, Alta. DESIGN: Retrospective chart review. SETTING: Primary care clinic for refugee patients. PARTICIPANTS: A total of 1390 new refugee patients at the clinic from May 1, 2011, to June 30, 2013. MAIN OUTCOME MEASURES: Stool ova and parasite test completion and proportion of positive test results. RESULTS: Of 1390 patients, 74.1% (95% CI 71.7% to 76.4%) completed at least 1 stool ova and parasite test. Among those completing tests, 29.7% (95% CI 26.9% to 32.6%) had at least 1 positive result. Patients aged 6 to 18 years were more likely to have positive test results (38.5%, 95% CI 32.2% to 45.0%) than patients aged 19 to 39 were, as were those last residing in Asia (36.4%, 95% CI 30.4% to 42.8%) or sub-Saharan Africa (30.9%, 95% CI 26.8% to 35.1%), compared with those arriving from the Middle East. Giardia lamblia, Blastocystis hominis, Dientamoeba fragilis, and Entamoeba histolytica or Entamoeba dispar were the most prevalent parasites. If B hominis and D fragilis are excluded because of their lower potential to cause harm, the overall prevalence was 16.3%. CONCLUSION: Given the high compliance of patients submitting stool ova and parasite tests and a high prevalence of positive test results in some refugee groups, targeted screening should be considered in newly arrived refugees at greater risk of intestinal parasites.

The sexuality and social performance of androgen-deprived (castrated) men throughout history: implications for modern day cancer patients.

Androgen-deprivation therapy (ADT) via either surgical or chemical castration is the standard treatment for advanced prostate cancer (PCa). In North America, it is estimated that more than 40,000 men start ADT each year. The side effects of this treatment are extensive and include gynecomastia, erectile dysfunction, and reduced libido. These changes strongly challenge patients' self-identity and sexuality. The historical term for a man who has been castrated is 'eunuch', now a pejorative term implying overall social and sexual impotence. In this paper, we review key historical features of eunuch social performance and sexuality from a variety of cultures in order to assess the validity of contemporary stereotypes of the androgen-deprived male. Data were taken from secondary sources on the history of Byzantium, Roman Antiquity, Early Islamic societies, the Ottoman Empire, Chinese Dynasties, and the Italian Castrati period. This cross-cultural survey shows that castrated men consistently held powerful social positions that yielded great political influence. Many eunuchs were recognized for their loyalty, managerial style, wisdom, and pedagogical skills. Furthermore, rather than being consistently asexual and celibate, they were often sexually active. In certain cultures, they were objects of sexual desire for males, or females, or both. Collectively, the historical accounts suggest that, given the right cultural setting and individual motivation, androgen deprivation may actually enhance rather than hinder both social and sexual performance. We conclude that eunuch history contradicts the presumption that androgen deprivation necessarily leads to social and sexual impotence. The capabilities and accomplishments of eunuchs in the past gives patients on ADT grounds for viewing themselves in a positive light, where they are neither socially impotent nor sexually chaste.
