Preoperative cleansing of the patient's skin with chlorhexidine-alcohol is superior to cleansing with povidone-iodine for preventing surgical-site infection after clean-contaminated surgery. (ClinicalTrials.gov number, NCT00290290.)

Most individuals desire from physicians all information concerning possible adverse effects of prescribed medication and do not favor physician discretion in these decisions.

Although most recent illicit drug users smoke, some are able to quit. Better understanding of concurrent cigarette and illicit drug use may provide impetus for policy change and shed light on underlying mechanisms of addiction. Clinicians, policy makers and user advocates should address tobacco use in drug treatment and in harm reduction interventions.

OBJECTIVE:To develop a meta-analysis to determine the effectiveness of rehabilitation in patients with chronic obstructive pulmonary disease (COPD).DATA SOURCES: MEDLINE, CINHAL, and Cochrane Library searches for trials of rehabilitation for COPD patients. Abstracts presented at national meetings and the reference lists of pertinent articles were reviewed.STUDY SELECTION: Studies were included if: trials were randomized; patients were symptomatic with forced expiratory volume in one second (FEV1) <70% or FEV1 divided by forced vital capacity (FEV1/FVC) <70% predicted; rehabilitation group received at least 4 weeks of rehabilitation; control group received no rehabilitation; and outcome measures included exercise capacity or shortness of breath. We identified 69 trials, of which 20 trials were included in the final analysis.DATA EXTRACTION: Effect of rehabilitation was calculated as the standardized effect size (ES) using random effects estimation techniques. RESULTS:The rehabilitation groups of 20 trials (979 patients) did significantly better than control groups on walking test (ES = 0.71; 95% confidence interval [95% CI], 0.43 to 0.99). The rehabilitation groups of 12 trials (723 patients) that used the Chronic Respiratory Disease Questionnaire had less shortness of breath than did the control groups (ES = 0.62; 95% CI, 0.35 to 0.89). Trials that used respiratory muscle training only showed no significant difference between rehabilitation and control groups, whereas trials that used at least lowerextremity training showed that rehabilitation groups did significantly better than control groups on walking test and shortness of breath. Trials that included severe COPD patients showed that rehabilitation groups did significantly better than control groups only when the rehabilitation programs were 6 months or longer. Trials that included mild/moderate COPD patients showed that rehabilitation groups did significantly better than control groups with both short-and long-term rehabilitation programs.CONCLUSION: COPD patients who receive rehabilitation have a better exercise capacity and they experience less shortness of breath than patients who do not receive rehabilitation. COPD patients may benefit from rehabilitation programs that include at least lower-extremity training. Patients with mild/ moderate COPD benefit from short-and long-term rehabilitation, whereas patients with severe COPD may benefit from rehabilitation programs of at least 6 months.KEY WORDS: rehabilitation; obstructive lung disease; shortness of breath; exercise; review.

This study compared the efficacy and tolerability of vigabatrin 3/day as add-on therapy with that of placebo in patients with focal epilepsy whose complex partial seizures were difficult to control with established antiepilepsy drug therapy. We enrolled 203 patients; 182 (90 placebo; 92 vigabatrin) received drug therapy under double-blind conditions. We increased the daily dosage to 2.5 g/day during a 4-week titration segment and maintained it at 3 g/day during the 12-week maintenance segment. By analyses we found a statistically significant lower frequency of seizures (complex seizures plus partial seizures secondarily generalized) at the end of the study for patients receiving vigabatrin than for those receiving placebo. The median monthly frequency was reduced by three seizures per 28 days in the placebo group (baseline, 8.3; end of study, 7.5) (p = 0.0002). Therapeutic success (a 50% reduction from baseline in mean monthly seizure frequency) was attained in 40 of the vigabatrin patients (43%) compared with 17 of those treated with placebo (19%) (p < 0.001). Vigabatrin significantly increased the mean number of seizure-free days per 28 days (2.2 days) compared with placebo (0.5 days) (p = 0.0024). Mean trough serum vigabatrin concentration during therapy was 8.6 +/- 7.7 micrograms/ml. The oral clearance of vigabatrin was determined to be 7.8 L/hr, and the elimination half-life was 8.4 hours. No clinically important changes in MRI, evoked potential, or other laboratory tests were noted during vigabatrin treatment. The results of this study indicate that 3 g/day vigabatrin is more effective than placebo as add-on therapy. Vigabatrin was well tolerated, compliance was high with twice-daily administration, and therapy did not result in clinically relevant drug interactions.

The majority of Kansans live near a mammography facility. Although there is a large variation in county-level mammography rates across Kansas, this disparity is not well explained by proximity to mammography facilities.

The IEVI reduced CR-BSIs and reactive depression and increased problem solving with professionals. IEVI use also can result in fewer hospitalizations and improved quality of life. Long-term improvement did not occur for reactive depression and problem-solving outcomes because patients used these less often.
