A prospective cohort study on the effectiveness of 3500 IU versus 5000 IU bemiparin in the prophylaxis of postoperative thrombotic events in obese patients undergoing orthopedic surgery.

Background: Postoperative thromboses are among the most feared complications in orthopedic surgery as they may cause life-threatening conditions in otherwise highly successful procedures such as total joint replacement. Body weight is an important risk factor for thromboses and is used in algorithms to determine dosages in prophylaxis. However, weight patterns among orthopedic populations have changed considerably since the introduction of these algorithms, essentially shifting towards obesity.

Long-term experience with Chiari's osteotomy.

Unlabelled: Fifty-six years after the introduction of Chiari's pelvic osteotomy, we report the long-term function scores and radiographic grade of osteoarthritis in 66 patients with 80 pelvic osteotomies with a minimum followup time of 27 years (average, 32 years; range, 27-48 years). These 66 patients were those who could be contacted and who returned for a followup visit from among 450 patients operated between 1961 and 1981. Thirty-two hips (40%) in 28 patients had undergone a total joint arthroplasty after an average 26 years (range, 13-41 years).

Feasibility of life-supporting first-aid (LSFA) training as a mandatory subject in primary schools.

Background: Life-supporting first-aid (LFSA) training in primary schools might prove a useful means of increasing cardiac arrest survival rates. We thus studied the feasibility of introducing first-aid training to 6-7-year old primary school children.

Methods And Results: During 1 week medical students and emergency physicians provided LSFA training to 47 first- and second-year pupils, including semi-automatic defibrillation.
