Despite decades of research many aspects of the biology of Mycobacterium tuberculosis remain unclear and this is reflected in the antiquated tools available to treat and prevent tuberculosis and consequently this disease remains a serious public health problem. Important discoveries linking M. tuberculosis's metabolism and pathogenesis have renewed interest in this area of research. Previous ex...

Members of the Mycobacterium tuberculosis complex (MTC) cause tuberculosis (TB) in both animals and humans. In this article, three animal-adapted MTC strains that are endemic to the southern African subregion - that is, Mycobacterium suricattae, Mycobacterium mungi, and the dassie bacillus - are reviewed with a focus on clinical and pathological presentations, geographic distribution, genotypin...

A prospective study of false-positive cultures of Mycobacterium tuberculosis that resulted from laboratory cross-contamination was conducted at three laboratories in California. Laboratory cross-contamination accounted for 2% of the positive cultures. Cross-contamination should be a concern when an isolate matches the genotype of another sample processed during the same period.

We have explored the added value of interferon-γ (IFNγ)-inducible protein 10 as a read-out of Mycobacterium tuberculosis-specific immunity in young Indian children, where the sensitivity of the IFNγ release assays for tuberculosis is poor. Reduced frequency of indeterminate results and an increased sensitivity for tuberculosis suggest a potential for fewer missed cases with a combined IFNγ/indu...

Here, we present the case of a 51-year-old man with limited-stage small cell lung cancer (LS-SCLC) who received concurrent chemoradiotherapy and photodynamic therapy (PDT). The patient was diagnosed as having LS-SCLC with an endobronchial mass in the left main bronchus. Following concurrent chemoradiotherapy, a mass remaining in the left lingular division was treated with PDT. Clinical and hist...

BACKGROUND Bedside diagnosis of patent ductus arteriosus (PDA) continues to be important, especially when echocardiography is not readily available. OBJECTIVE The aim of our study was to evaluate whether measurement of left main bronchus displacement portrayed on a chest X-ray as a widened carina angle (CA) may support the presumptive diagnosis of PDA. METHODS Displacement of the left bronc...

Background, methods and results We report herein the cases of two patients with bronchial carcinomas in the left main bronchus who were successfully treated by left sleeve pneumonectomy performed through a sternotomy incision for the first time in Bulgaria. Adequate oxygenation during tracheobronchial anastomoses was achieved by cardiopulmonary bypass in both patients. Tracheobronchial anastomo...

Video-assisted thoracoscopic surgery (VATS) is an approach to resection of bronchogenic cysts (BC) which is effective and viable. There may be complications as a result of pericystic adhesions to neighboring structures during dissection. This report describes an unusual case of an operative complication, the rupture of the main left bronchus. The initial VATS approach was converted into a right...

Introduction. We herein report our experience with new fully covered self-expanding metallic stents in the setting of inoperable recurrent benign tracheobronchial stenosis. Methods. Between May 2010 and July 2014, 21 Micro-Tech® FC-SEMS (Nanjing Co., Republic of Korea) were placed in our hospital in 16 patients for inoperable, recurrent (after dilatation), and symptomatic benign airway stenosis...
