BACKGROUND: Although the clinical features of infants with congenital tuberculosis (TB) are well established, the features of infants exposed to TB in utero including those who are non-infected, are not well reported. TB-exposed infants are at risk of developing TB post-delivery, and chemoprophylaxis, usually isoniazid, is therefore recommended. Isoniazid/rifampicin combined is an alternative, but little is known about its effectiveness. OBJECTIVE: To determine the clinical features of infants exposed to TB in utero and the proportion who develop TB infection and disease despite chemoprophylaxis with a 3-month course of isoniazid/rifampicin...

INTRODUCTION: Cough is a key symptom of tuberculosis (TB) as well as the main cause of transmission. However, a recent literature review found that cough frequency (number of coughs per hour) in patients with TB has only been studied once, in 1969. The main aim of this study is to describe cough frequency patterns before and after the start of TB treatment and to determine baseline factors that affect cough frequency in these patients. Secondarily, we will evaluate the correlation between cough frequency and TB microbiological resolution...

There have been concerns about an association of fluoroquinolone (FQ) use prior to tuberculosis (TB) diagnosis with adverse outcomes. However, FQ use might prevent clinical deterioration in missed TB patients, especially in those who are immunocompromised, until they receive definitive anti-TB treatment. All adult immunocompromised patients with smear-negative and culture-positive TB at a tertiary care hospital in Korea over a 2-year period were included in this study. Long-term FQ (≥7 days) use was defined as exposure to FQ for at least 7 days prior to TB diagnosis...

Pulmonary paragonimiasis is a food-borne zoonosis with a wide variety of radiologic findings, which sometimes can be confused with tuberculosis and carcinoma. Therefore, differential diagnosis is always warranted. A 43-year-old male farmer, with productive cough, blood-tinged sputum and chest pain, as well as patchy consolidation and pleural effusions in chest computer tomography, was misdiagnosed of community-acquired pneumonia and tuberculosis. Complete blood cell count, sputum smear and culture, chest computer tomography, thoracoscopy, and biopsy...

South Africa has one of the highest incidences of tuberculosis (TB) worldwide due to the ongoing human immunodeficiency virus (HIV) epidemic. There are, however, no reports on peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients due to Mycobacterium tuberculosis in South Africa. The aim of this study is to discuss our experience of tuberculous peritonitis in CAPD patients from a rural endemic area of South Africa. This is a retrospective descriptive study of CAPD patients diagnosed with mycobacterium peritonitis infection from January 2008 to August 2014 at the Limpopo Kidney and Dialysis Centre (LKDC) in South Africa...

BACKGROUND: Control of the global burden of tuberculosis is obstructed due to lack of simple, rapid and cost effective diagnostic techniques that can be used in resource poor-settings. To facilitate the early diagnosis of TB directly from clinical specimens, we have standardized and validated the use of nested multiplex PCR, targeting gene fragments IS6110, MTP40 and 32kD α-antigen encoding genes specific for Mycobacterium tuberculosis complex and non-tubercular mycobacteria (NTM), in comparison to smear microscopy, solid culture and single step multiplex PCR...

INTRODUCTION: Smear-negative pulmonary TB (SNPT) represents 30-60% of all pulmonary TB cases. The mortality of these patients can reach 25% in populations with high prevalence of HIV infection, and 10-20% of TB transmission at the population level are attributable to SNPT cases. METHODS: We conducted a retrospective study to evaluate epidemiological, clinical, and radiological characteristics of patients with SNPT and to compare these with patients who were diagnosed as having smear-positive pulmonary TB (SPPT)...

BACKGROUND: Tuberculosis (TB) is a mycobacterial infection mainly affecting the lungs. Early and correct diagnosis of sputum smear negative patients by chest radiography (CXR) is challenging since it depends on reader's ability to detect abnormal findings and to interpret it correctly. OBJECTIVES: To evaluate the validity and reliability of CXR the diagnosis of TB among smear negative pulmonary tuberculosis (PTB). METHODS: An institutional based cross-sectional study was conducted at seven selected health facilities from October 2011 to September 2012 on 159 adults aged 18 years and above who were newly diagnosed smear negative for PTB patients diagnosed using Chest X-ray (CXR)...

BACKGROUND: Tuberculosis (TB) in children is neglected, mainly due to lack of sensitive diagnostic tools. Recently Xpert MTB/RIF assay has revolutionized the diagnostic field, but its usefulness in pediatric TB has not been reported from India and no report is available on its use on long term archived samples. METHODS: We recruited 130 pediatric patients with probable intrathoracic tuberculosis and their gastric aspirate (GA) and induced sputum (IS) samples on 2 consecutive days were collected between January 2009 and December 2012...

Tuberculous infection of the tracheobronchial tree, termed as endobronchial tuberculosis (EBTB), is more common in young adults and females. This clinical entity is poorly understood and the diagnosis is frequently delayed as sputum smears are often negative for acid fast bacilli and the chest radiograph can be normal, resulting in diagnostic confusion. Bronchoscopy continues to play a key role in its diagnosis. Though atelectasis is not uncommon in these patients, EBTB presenting as a middle lobe syndrome (MLS) has rarely been documented...

BACKGROUND: Xpert MTB/RIF has been shown to have a superior sensitivity to microscopy for acid fast bacilli (AFB) in sputum and has been recommended as a standard first line investigation for pulmonary tuberculosis (PTB). Bronchoscopy is a valuable tool in diagnosing PTB in sputum negative patients. There is limited data on the utility of Xpert MTB/RIF performed on bronchial lavage specimens. Our aim was to evaluate the diagnostic efficiency of Xpert MTB/RIF performed on bronchial washings in sputum scarce/negative patients with suspected PTB...
