[Ivory Coast physician's knowledge and attitudes about smoking in patients with tuberculosis]. / Connaissances et attitudes des médecins ivoiriens vis-à-vis du tabagisme chez les patients atteints de tuberculose.

INTRODUCTION: Smoking promotes, among other health problems, the development of tuberculosis and the discovery of a case of tuberculosis can therefore be an opportunity for tobacco control interventions. METHODS: We conducted a prospective study evaluating the knowledge of 37 Ivorian physicians (32 men and 5 women with 5 active smokers) on the relationship between smoking and tuberculosis and their attitudes to smoking tuberculous patients between February and August 2012 using an anonymous self-administered questionnaire. RESULTS: The response rate to the questionnaire was 88.1%. Among them, 70.3% of Ivorian physicians knew that smoking increased the incidence of tuberculosis, 75.7% said that forms of tuberculosis were more severe in smokers and about 27% thought that the cure rate of tuberculosis was lower in smokers. No significant difference was observed according to respondents' smoking status, or gender. Patients' smoking status was always assessed by 64.9% of physicians and by 78.4% in patients with tuberculosis, again not differing by physicians' smoking status or gender. The risks of smoking were always explained to patients with active pulmonary tuberculosis by 43.2% and benefits of stopping smoking ware always described in 35.1%. An intervention for smoking cessation was systematically offered to smokers having tuberculosis by 59.4% of physicians and 8.1% offered medication for smoking cessation. CONCLUSION: These results strongly support the need to reinforce physician behaviors to address smoking in patients with tuberculosis in Ivory Coast.

Effectiveness of 3-in-1 continuous femoral block of differing concentrations compared to patient controlled intravenous morphine for post total knee arthroplasty analgesia and knee rehabilitation.

We assessed the effectiveness of the 3-in-1 continuous femoral block as a form of postoperative pain relief for unilateral total knee arthroplasty (TKA). Sixty patients undergoing elective unilateral TKA under subarachnoid block were randomized into three groups. Postoperative analgesia was provided with a continuous 3-in-1 femoral nerve catheter with 0.15% ropivacaine in group A, a continuous 3-in-1 femoral nerve catheter with 0.2% ropivacaine in group B, or patient controlled intravenous morphine in group C (control group). Groups A and B received patient controlled intravenous morphine pumps for rescue analgesia. Patients in each group were followed for 72 hours postoperatively. Five patients were excluded after randomization. In the remaining 55 patients there was no statistical difference in pain score between the groups. Total morphine use was highest in group C (P < 0.05). No appreciable difference could be found with sensorimotor blockade, morphine usage and satisfaction scores when comparing groups A and B. Femoral catheter dislodgement rate was 7.9%. There was no statistical difference between the groups when comparing the day of first ambulation and the time to discharge from the hospital. Satisfaction scores were higher in group A (P = 0.028) and group B (P = 0.002) compared to group C. We conclude that a continuous 3-in-1 femoral nerve block with ropivacaine 0.15% or 0.2% for elective unilateral TKA has an opioid-sparing effect.

Serum micronutrients and cervical dysplasia in Southwestern American Indian women.

We carried out a clinic-based case-control study to assess serum micronutrients as risk factors for cervical dysplasia among Southwestern American Indian women, a group with high rates of cervical preinvasive lesions. Cases were American Indian women with biopsy-proven cervical intraepithelial neoplasia (CIN I or CIN II/III). Controls were from the same Indian Health Service clinics with normal cervical epithelium. We interviewed women about histories of sexually transmitted diseases, sexual behavior, diet, hygienic practices, cigarette smoking, and reproductive factors. Laboratory assays included serum for retinol (vitamin A), ascorbic acid (vitamin C), alpha-tocopherol (vitamin E), and red blood cell folate levels, DNA for human papillomavirus (HPV) typing, and tests for other sexually transmitted diseases. The strongest risks for cervical dysplasia were associated with cervical HPV infection [odds ratio (OR) = 3.2, 95% confidence interval (CI) = 2.2-4.6 and OR = 7.9, 95% CI = 4.8-13.1 for CIN I and CIN II/III, respectively]. With adjustments made for HPV infection and other relevant confounders, subjects in the lowest serum retinol quartile were at increased risk of CIN I compared with women in the highest quartile (OR = 2.3, 95% CI = 1.3-4.1). The data suggest that low serum alpha-tocopherol was associated with CIN I/III, although the adjusted OR was not statistically significant (OR = 2.0, 95% CI = 0.9-4.8). Low serum ascorbic acid and red blood cell folate were not associated with cervical dysplasia.
