PURPOSE: To compare the effects of alendronate and raloxifene on lumbar bone mineral density (BMD), bone turnover, and lipid metabolism in elderly women with osteoporosis. Subjects and Methods: One hundred twenty-two postmenopausal women with osteoporosis (mean age: 69.4 years) were randomly divided into 2 groups of 61 patients: the alendronate group and the raloxifene group. BMD of the lumbar spine, urinary level of cross-linked N-terminal telopeptides of type I collagen (NTX), and serum levels of alkaline phosphatase (ALP), total cholesterol (TC), high and low density lipoprotein cholesterols (LDL-C and HDL-C, respectively), and triglycerides (TG) were measured during the 12-month-treatment period. RESULTS: The trial in 50 patients in the alendronate group and 52 patients in the raloxifene group could be completed. Both alendronate and raloxifene increased lumbar BMD (+8.0% and +2.4% at 12 months, respectively), followed by reductions of urinary NTX level and serum ALP level; however, the effects of alendronate were more pronounced than those of raloxifene. Only raloxifene reduced the serum levels of TC and LDL-C (-3.9% and -7.7% at 12 months, respectively), without any significant effect on the serum HDL-C and TG levels. CONCLUSION: The present study confirmed the efficacy of alendronate greater than raloxifene in increasing lumbar BMD through its effect on marked reduction of the bone turnover more than by raloxifene, and some beneficial effects of raloxifene on lipid metabolism in elderly women with osteoporosis.

PURPOSE: The comparative effects of alendronate and alfacalcidol on bone mineral density (BMD) and bone turnover have already been established in postmenopausal women with osteoporosis. An open-labeled prospective study was conducted to compare the treatment effects of alendronate and alfacalcidol on hip BMD and bone turnover in Japanese men with osteoporosis or osteopenia with clinical risk factors for fractures. MATERIALS AND METHODS: One hundred twelve men with osteoporosis or osteopenia with clinical risk factors for fractures (mean age: 71.4 years) were randomly divided into two groups of 56 patients each: the alendronate (5 mg daily) and alfacalcidol (1 microgram daily) groups. The BMD of the total hip, urinary level of cross-linked N-terminal telopeptides of type I collagen (NTX), and serum levels of bone-specific alkaline phosphatase (BSAP) were measured during the 12-month-treatment period. RESULTS: Forty-five patients in the alendronate group and 42 patients in the alfacalcidol group completed the trial. Alendronate increased BMD (+2.3% at 12 months) following reductions in the urinary level of NTX (-46.4% at 3 months) and serum level of BSAP (-34.1% at 12 months), while alfacalcidol sustained BMD (-1.9% at 12 months) as well as the urinary level of NTX (+13.2% at 3 months) and serum level of BSAP (+1.8% at 12 months). CONCLUSION: The present study confirmed that alendronate has better efficacy than alfacalcidol (active control) in increasing hip BMD and reducing bone turnover in Japanese men with osteoporosis or osteopenia with clinical risk factors for fractures.

Objectives: Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) is a risk factor for surgical site infections (SSIs). However, few studies have evaluated the rate of nasal carriage of MRSA and its effect on SSIs in patients undergoing general thoracic surgery. We investigated the importance of preoperative screening for nasal carriage of MRSA in patients undergoing general thoracic surgery.Patients and Methods: We retrospectively analyzed 238 patients with thoracic diseases who underwent thoracic surgery. We reviewed the rates of nasal carriage of MRSA and SSIs.Results: Results of MRSA screening were positive in 11 of 238 patients (4.6%), and 9 of these 11 patients received nasal mupirocin. SSIs occurred in 4 patients (1.8%). All 4 patients developed pneumonia; however, MRSA pneumonia occurred in only 1 of these 4 patients. No patient developed wound infection, empyema, and/or mediastinitis. SSIs did not occur in any of the 11 patients with positive results on MRSA screening.Conclusions: The rates of nasal carriage of MRSA and SSIs were low in this case series. Surveillance is important to determine the prevalence of MRSA carriage and infection in hospitals, particularly in the intensive care unit. However, routine preoperative screening for nasal carriage of MRSA is not recommended in patients undergoing general thoracic surgery.
