most people infected with m .tuberculosis do not develop active disease. in healthy individuals, the lifetime risk of developing infection to disease is 5-10%. reactivation of tb often occurs in older children and adolescent and is more common in patients who acquire tb at age 7 years and older. pulmonary tuberculosis may manifest in several forms, including endobronchial tb with focal lymphade...
BACKGROUND Quick diagnosis of smear-negative pulmonary tuberculosis (TB) and extra-pulmonary TB are urgently needed in clinical diagnosis. Our research aims to investigate the usefulness of the interferon-γ release assay (IGRA) for the diagnosis of smear-negative pulmonary and extra-pulmonary TB. METHODS We performed TB antibody and TB-IGRA tests on 389 pulmonary TB patients (including 120 sm...
from january 1982 to april 1987 , 1500 cases of fiberoptic bronchoscopy (fob) were performed. among these cases, 37 were suspected of having pulmonary tuberculosis but their sputum examination was either negative or they were not able to expectorate. in all these cases pulmonary tb was confirmed either by bronchoalveolar lavage (bal) fluid examination or by biopsy. we conclude that fob is a val...
background : despite recent technologic improvements in identifying mycobacterium tuberculosis, we are still facing problems in rapid diagnosis of tuberculosis. the objective of this study is to determine the diagnostic value of a new rapid screening test (patho-tb™) for diagnosis of pulmonary tuberculosis. methods : between september 2006 to august 2007, 178 patients were enrolled in the study...
Background and purpose: TB is a serious infectious disease in kidney recipients causing high morbidity and mortality. The prevalence of this disease varies in different countries depending on socio-economic levels. The aim of this study was to investigate the occurrence of TB after kidney transplant in kidney transplant center of Shahid Beheshtei Hospital in city of Babol. Materials and method...
Introduction: Primary tuberculosis (TB) of the oropharynx and nasopharynx is an extremely rare form of extra-pulmonary TB in children. Primary tuberculosis occurs more likely secondary to pulmonary TB and is more common in immunocompromised patients. Case Report: We reported the case of a young male presented with the symptoms of non-specific chronic adenotonsillitis, ...
Background and purpose: Tuberculosis (TB) is created by Mycobacterium tuberculosis. Application of Geographical Information System (GIS) is of great benefit in understanding the geographical pattern of TB and strengthens its control programs. This study was performed in Guilan, Iran to determine the geographical pattern of TB in this province. Materials and methods: The present ecological stu...
Tuberculos Gumma is one of the various clinical manifestations of cutaneous TB that is characterized by non tender, undolent subcutaneous nodules which progressively involve the skin and take the appearance of an ulcer. In this article, we present two young patients, affected with tuberculos gumma. One of them, presented with multiple abcesses on the face and extremities, associated with pulmon...
Most cases of adult-onset tuberculosis (TB) result from reactivation of a pre-existing Mycobacterium tuberculosis infection. Mycobacterium tuberculosis usually invades the respiratory tract and most patients develop intrapulmonary TB; however, some patients develop concurrent pulmonary and extra-pulmonary TB. The purpose of the present study was to identify the demographic and clinical factors ...
BACKGROUND Mycobacterium tuberculosis infection is a leading cause of infectious death worldwide. Gene-expression microarray studies profiling the blood transcriptional response of tuberculosis (TB) patients have been undertaken in order to better understand the host immune response as well as to identify potential biomarkers of disease. To date most of these studies have focused on pulmonary T...
