Summary: In this prospective study, we measured bone mineral density (BMD) in 1,041 cancer patients undergoing an oncological rehabilitation program in an inpatient rehabilitation clinic. There was an osteoporosis prevalence of approximately 16%, independent of sex, which is considerably higher than in the community-dwelling population. Introduction: There is evidence that cancer patients are at risk of an increased BMD-loss following the disease and its therapy. Nevertheless, there is only little data available about the prevalence of osteoporosis in German cancer patients. Therefore, we measured BMD in 1,041 oncological inpatients undergoing rehabilitation. Methods: From February 2006 to September 2009, BMD was measured in oncological patients with dual-energy x-ray absorptiometry (DXA; femur and spine). Statistical analysis for prevalence of osteoporosis was done in descriptive manner calculating means, standard deviation, frequencies, and 95% confidence intervals. To compare the prevalence of osteoporosis in different subgroups, χ tests were done with p < 0.05. To create a risk profile, odds ratios were calculated using uni- and multivariate logistic regression. Results: In 1,041 patients with a mean age of 57.1 years (11.0 years), DXA-measures were performed. Of them, 22% were male and 78% were female. The osteoporosis prevalence was about 16% (13.8, 18.2), independent of sex ( p = 0.9722) or cancer type ( p = 0.7174). As risk factors influencing the development of osteoporosis, age, weight, menopausal state, and hormone replacement therapy were identified in women and weight only in men. Conclusions: Compared to the general population, the rate of osteoporosis is distinctly elevated in German cancer patients independent of sex or cancer type. Hence, a general recommendation for a DXA screening in these patients appears to be justified. [ABSTRACT FROM AUTHOR]

This article presents a "protest" from several professors about the study of sociology in Germany. The authors write that the subject seems to have grown "tired." The authors write that there are fewer chances for advancement for younger sociologists. The authors also cite the increase in non-university sociological study, which has led, in their opinion, to an erosion of the study and teaching at the university level.

The article reports on the therapeutic complication of a 51-year-old man with star anise and celery-carrot-mugwort-spice syndrome after treating it with Oseltamivir phosphate in Germany. The therapeutic complications of the patient includes cough, angioederma and airway constriction. It also cites the intuitive hypersentivity reaction to Oseltamivir phosphate in patient having Chinese star anise sensitization.

This article describes a cohort study investigating incidence of testicular tumors in car manufacturing workers in Germany. A cluster of testicular tumors in one car manufacturing plant gave rise to a suspected occupational cause. Exposure to electromagnetic fields during resistance welding operations was considered a possible hazard. The cohort comprised 1,67,212 men employed between 1989 and 2000 in six different plants. Over the study period, 160 incident cases were identified through health insurance records. Internal comparisons between departments and plants were carried out using Cox regression. The internal comparison revealed increased risk ratios in the following work areas, where all other areas served as reference: maintenance, administration/office work, and machine assembly.
