ABSTRACT
UNLABELLED: We describe complementary and alternative medicine use (CAM) in 360 patients attending osteoporosis clinics. Of these patients, 57% were CAM users. Predictors of CAM use included lower mental quality of life, younger age and higher education. Less than half of CAM use was disclosed to physicians, despite potential adverse interactions. INTRODUCTION: The prevalence of complementary and alternative medicine (CAM) use in osteoporosis clinics is not known. The objective of this study was to describe the pattern of CAM use in this population. METHODS: We performed a cross-sectional study of 360 patients attending academic osteoporosis clinics in Toronto, Canada in 2001. Subjects completed a self-administered questionnaire on CAM use. Health-related quality of life (HQL) was measured with the Short-Form 36v2. Comparative statistics and logistic regression were performed to identify sociodemographic, HQL and clinical correlates of CAM use. RESULTS: More than 80% of participants were women, Caucasian and had at least a high school education. Of subjects, 57% used CAM in the previous year. Only 44% of CAM use was disclosed to a medical doctor. CAM users and non-users did not differ in clinical characteristics such as bone mineral density, level of comorbidity and fracture history. In univariate analysis, CAM users were less satisfied with conventional medicine. However, when we explored patient satisfaction, comorbidities and sociodemographic as predictors for CAM use, the multivariable analyses showed that lower mental HQL, younger age, and post-secondary education were the only significant predictors. We identified 35 cases in which the utilization of CAM supplements could possibly exacerbate existing medical conditions. CONCLUSION: Patients attending osteoporosis clinics frequently use CAM. Conceptually, the predictors of use identified in this study may fit into a socio-behavioral model that helps explain why people turn to CAM. Physicians may need to elicit a history of CAM use more vigilantly so as to better screen for possible adverse clinical interactions.

The authors report a case of an endogenous Nocardia asteroides subretinal abscess in an immunosuppressed cardiac transplant recipient. On clinical grounds, the metastatic subretinal abscess was initially thought to be a fungal, atypical bacterial, or viral lesion. Transvitreal fine-needle aspiration biopsy of the lesion yielded a sufficient specimen for immediate preliminary identification of the microorganism and permitted prompt initiation of an appropriate antibiotic regimen. The definitive diagnosis was based on culture of the organism from the needle aspirate.

The authors observed clinical regression of an apparent primary choroidal melanoma in a 66-year old man over an eight-year interval. This regression was documented photographically and ultrasonographically. The authors discuss the possible mechanisms responsible for this clinical course.

Cells bearing immunoglobulin (Ig) can be enumerated by current methods, but cells secreting Ig (with unknown antibody specificity) can not. By using a reverse plaque-forming cell assay, we counted the Ig-secreting cells in the blood of nonimmunized individuals. Isolated human lymphocytes were plated in gels together with erythrocytes coated with purified antibody to human Ig. After treatment with anti-Ig antibody and complement, the Ig-secreting cells formed hemolytic plaques. In 10 normal individuals, 1.2 +/- 0.4% of the plated mononuclear cells formed plaques; in an individual tested on 7 different days during 3 months, 1.1 +/- 0.2% of the cells formed plaques. From the number of mononuclear cells in the blood, we calculated 22 +/- 8 Ig-secreting cells per mm3 of blood. Enumerating Ig-secreting cells is a new direct assay for a B cell function and need not correlate with quantitating serum Ig. Thus, this assay should be useful for studying Ig-secretion in normal and altered states.
