In order to try to improve the results of direct smear microscopy, we used the mucus-digesting quality of chitin in tuberculosis (TB) laboratories. For this purpose, a total of 430 sputum specimens were processed by the N-acetyl-L-cysteine concentration, sodium hypochlorite (NaOCl) liquefaction, chitin sedimentation, and direct microscopy methods. Then, the(More)

There is little information on atypical mycobacterium and human T lymphotropic virus Type I (HTLV-I) co-infection. We present the first case of pulmonary M. simiae infection in co-infection with HTLV-1, confirmed by ELISA antibody test and Western Blot. We discuss the clinical characteristics and laboratory tests of the patient and presumptive immunological(More)
IL-2-inducible T-cell kinase (ITK) deficiency is a rare inherited immunodeficiency disease characterized by homozygous mutations in the ITK gene and the inability to control Epstein-Barr virus (EBV) infection leading to EBV-associated lymphoproliferative disorders of B cell origin. Many aspects of its clinical presentation and immunologic phenotype are(More)
Nearly 18% of tuberculosis (TB) cases have only extrapulmonary manifestations. Breast tuberculosis is a rare type of extrapulmonary TB. This paper reports 4 cases of breast TB confirmed either pathologically or mycobacteriologically or both. These reports showed that TB should always be considered first in the differential diagnosis of granulomatous(More)
BACKGROUND Multidrug-resistant tuberculosis (MDR-TB) imposes a formidable burden on national health systems. There is still no consensus on the subject, with controversies regarding treatment protocols, treatment outcomes and the various treatment regimens. METHODS The present study describes Iran's second national cohort for treatment of MDR-TB. The(More)
The study assessed reasons for delay between patient's first symptoms of tuberculosis and initiation of therapy. Fifty newly diagnosed cases of pulmonary tuberculosis admitted to the NRITLD in Teheran were studied. Mean patient delay before consulting a physician was 12.5 +/- 10 days, significantly higher among men than women. Mean delay until the(More)
We describe the efficacy and outcome of standardised second-line anti-tuberculosis (TB) medications during pregnancy. Treatment outcomes of five pregnant women with documented multidrug-resistant TB (MDR-TB) referred to the National Research Institute of Tuberculosis and Lung Diseases from 2003 to 2009 were analysed in two categories, maternal and neonatal.(More)
SETTING Health care clinics and private practitioners in Tehran. OBJECTIVE To analyse rates of drug resistance and response to treatment in tuberculosis patients. DESIGN A prospective study of 257 patients undergoing treatment for whom data were collected on drug susceptibility testing and outcome as well as age, sex and history of treatment. RESULTS(More)
In the Eastern Mediterranean Region (EMRO), there are no accurate estimates of numbers of patients with multidrugresistant (MDR)/extensively drug-resistant (XDR) tuberculosis (TB). In 2006, we documented the existence and transmission of XDR-TB among patients with MDR-TB [1]. In a further study, we isolated more dangerous forms of bacilli, named totally(More)
