https://www.selleckchem.com/products/az32.html A 78-year-old woman presented with an atypical femoral fracture of her right femur associated with a left thigh stress fracture following 9 years of bisphosphonate therapy. The fracture was managed with femoral nailing. However, she represented 3 years later with peri-prosthetic infection, worsening of the left-side stress fracture, and low bone turnover in a bone metabolic study, consistent with an ongoing bisphosphonate effect. This case highlights the increased rate of postoperative complications in atypical femoral fractures even years after surgery as well as the challenging management issues for contralateral fracture and the risk of missing bilateral fractures. We aimed to analyse the trends in ageism among health care providers and medical students in the Republic of Korea. We used the Fraboni Scale of Ageism (FSA), Relating to Older People Evaluation (ROPE) questionnaire, Anxiety about Aging Scale (AAS), and the Facts on Aging Quiz II to assess ageism in medical students (n=90), nurses (n=114), and physicians (n=83). We grouped health care providers based on the percentage of aged patients (over 65 years) that they treated. Compared to the other groups, physicians had more knowledge about aging and the highest and lowest total scores in the FSA and ROPE, respectively. The total FSA scores were negatively correlated with the percentage of aged patients treated. Regarding the ROPE score, negative and positive ageist behaviors were positively correlated with the percentage of aged patients. Ageism and ageist behavior among physicians differed from previous reports and those of the other groups mentioned in the present study. Although physicians had more knowledge of aging, they had expressed a high levels of ageism. However, they did not act ageistically. Health care providers who treat a large number of older patients had minimal ageism but more ageist behavior. These findings indicate that continued education of
