Background
Tuberculosis (TB) is an infectious bacterial disease; remains as one of the important public health problem affecting every part of the world. Substantial number of TB cases are reported from Sri Lanka every year irrespective of its strong preventive health system. The aim of this analysis is to describe the characteristics of TB patients and to assess the factors associated with sputum conversion. This analysis was based on the data from the District Chest Clinic of Kalutara district, Sri Lanka.Methods
Information of all newly diagnosed and registered patients in the District Chest Clinic, Kalutara in year 2013 were ascertained. Out of 687 newly reported TB patients, 669 records were included in final analysis.Results
Majority of patients were males (n = 451, 67.4%), in the age group of 36–60 years (n = 306, 45.7%) and underweight (n = 359, 61.7%). Substantial proportion of normal weight or overweight adult patients (92.1%) had sputum conversion at 2–3 months as compared to underweight adult patients (82.5%) (p = 0.034). Those who smoke tobacco is less likely to have sputum conversion at 2–3 months as compared to non-smokers (90.2% vs. 82.1%, p = 0.045).Conclusion
Provision of good nutrition, maintaining of appropriate body mass index (i.e., BMI), and abstinence from smoking and alcohol consumption are important for sputum conversion among smear-positive pulmonary TB patients. 相似文献3.

Active and passive immunization with Pseudomonas aeruginosa ribosomal vaccines and antisera in the burned rat model 总被引:1,自引:0,他引:1
Pseudomonas aeruginosa ribosomal vaccines were tested for their ability to protect rats subjected to a 20% total body surface burn against the lethal effects of infection with homologous organisms. When administered prior to burning, the vaccines provided 100% protection. When administered postburning, the vaccine from one strain also provided 100% protection when the time interval between vaccination and infection was 3 days. When this time interval was reduced to 1 or 2 days, approximately 50% protection was obtained with the same vaccine. The vaccine from a second strain tested provided about 50% protection with a 3-day time interval. In addition, passive immunization using antiserum to a ribosomal vaccine was also demonstrated to be effective in protecting burned and infected rats, especially when multiple doses of antiserum were used. In this case, 80% protection was obtained (with no protection observed using multiple doses of normal serum). Finally, a comparison of ribosomal and lipopolysaccharide vaccines and antisera was also performed. 相似文献

A case of Zollinger-Ellison syndrome in an elderly man who presented with dysphagia and subsequently developed esophageal stricture is described. This is an infrequent concomitant of the Zollinger-Ellison syndrome, especially as a presenting complaint. The literature on esophageal involvement in the Zollinger-Ellison syndrome is briefly reviewed. 相似文献

OBJECTIVE: This study was undertaken to determine whether obesity is a risk factor for failed trial of labor (TOL) in women with previous cesarean delivery (CD). STUDY DESIGN: We performed a review of singleton gestations 36 weeks or greater with previous CD who underwent TOL from January 1998 to June 2002, stratifying by body mass index (BMI, kg/m2): normal (BMI <25), overweight (BMI 25-29.9), obese (BMI 30-39.9), and morbidly obese (BMI >40). Rates for failed TOL were determined, and groups compared. RESULTS: For 725 patients, failed TOL rates were as follows: 14.1%, 20.4%, 27.7%, and 30.3% for normal, overweight, obese, and morbidly obese groups, respectively (P < .0001). Significant risk factors included: no previous vaginal delivery, labor induction, recurrent CD indication, and fetal macrosomia. However, obesity remained an independent risk factor for failed TOL in the obese and morbidly obese groups with odds ratio of 1.99 (95% CI 1.20-3.30) and 2.22 (1.11-4.44) for these groups (P = .03), respectively. CONCLUSION: Obesity is an independent risk factor for failed TOL in patients with previous CD. 相似文献
