Tuberculosis being a communicable disease or transferrable disease, it is easily passed down to other person who remains in contact to the infected person by the process of inhaling air droplets carrying that particular bacteria. Tuberculosis mainly affects the lungs, but it can also affect the other organs. When this bacteria encounters in the body, the immune cells checks and control pathogen. However this disease remains latent but can become active at any time after some years when the particular immune system is weakened. If this disease is not treated at that time, then this disease can also become life- threating illness.","PeriodicalId":74235,"journal":{"name":"Mycobacterial diseases : tuberculosis & leprosy","volume":"8 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2161-1068.1000263","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70585341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To add to the burden, drug resistant TB is on the rise and India is handling the dual burden of drug sensitive TB and resistant TB. Previously treated TB cases when compared to the newly diagnosed, have poor treatment success rates and nearly seven times higher incidence of multi drug resistant TB. Proper management of patients treated with Category-II anti-tuberculous treatment (ATT) can result in decrease in emergence of drug resistant bacilli and interruption of disease transmission. Very few studies have reported the treatment outcomes of re-treatment cases and the associated factors in the literature. Favourable outcome rates are highly variable among the failure, relapse and default subgroups. There are many challenges faced by the treating physicians in diagnosis, treatment and follow-up of the re-treatment cases. This review describes the outcomes of patients treated with Category-II ATT and the challenges in managing the previously treated cases successfully.

The aim of the study was to assess the effect of prognostic factors associated with time to recovery of adult TB patients who were under treatment follow-up of Mizan-Tepi University Teaching Hospital. Study Design: A retrospective cohort study. Methods: The data was obtained from medical records of TB patients registered during September 2011 to August 2016 and treated under the DOTS program. Kaplan-Meier and Cox proportional hazards model were applied. Backward selection procedure was used in variable selection. Results: In this study, 75% were recovered, 4.4% died, 9.7% defaulted, and 4.9% failure, while 6% transferred out rate. The median recovery time of the patients was 185 days (6 months and 5 days) but it varies depending on the covariates included in the study. TB Type (P<0.001), family size (P=0.035), Co-morbidity (P=0.045) and bodyweight (P=0.044) at baseline had a statistically significant. Conclusion: The effects of TB type, family size, co-morbidity and bodyweight at baseline had a statistically significant impact on time-to-recovery. The variables that are significant should be considered during the selection phase a treatment (combination of treatments) for TB.","PeriodicalId":74235,"journal":{"name":"Mycobacterial diseases : tuberculosis & leprosy","volume":"8 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70585036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: The aim of this study was to evaluate common clinical features amongst individuals with bronchoscopic biopsy proven EBTB during a 20 year period in Serbia. Design: An observational study of 212 patients with bronchoscopic biopsy proven EBTB between January 1993 and December 2012. Retrospective case note review was undertaken, including all clinical, microbiological and radiological evidence, at the University Hospital of Pulmonology, Belgrade. Results: All patients were caucasian and HIV-negative, with a male to female ratio of 1.28:1. Every patient had an abnormal chest X-ray. The most common endoscopic features were oedematous hypereamic (39.2%) and nonspecific bronchitis (35.8%). Microbiological culture rate was 64.6%. Sputum culture was positive in 55.2%, bronchial washing culture positive in 36.8%, and both in 27.4%. Conclusion: Most patients with EBTB have concurrent pulmonary lesions. Bronchoscopy is an essential diagnostic tool for EBTB. Early diagnosis and early onset of therapy is of crucial importance to prevent the development of bronchostenosis.","PeriodicalId":74235,"journal":{"name":"Mycobacterial diseases : tuberculosis & leprosy","volume":"11 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70585621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
