We here report the case of an 18-year-old man with a giant yolk sac tumor that is resected under percutaneous cardiopulmonary support (PCPS). Because this patient had severe dyspea when he lay in a supine position, we resected the tumor. We used PCPS during the operation for the induction and maintenance of ventilation because his trachea and left main bronchus were collapsed by the tumor. Also...

Primary endobronchial schwannomas are extremely rare tumors that originate from Schwann cells. We report a case of primary endobronchial schwannoma. A 44-year-old woman, without respiratory symptoms, was presented with a nodule in the left main bronchus on her chest computed tomography scan. The nodule was removed by a rigid bronchoscopy with argon plasma coagulation. Biopsy confirmed the diagn...

Cutaneous complications caused by a pacemaker or defibrillator are widely documented, but the development of a bronchocutaneous fistula has never been described before. We report the case of a 79-year-old man who was admitted to our hospital because of a seemingly superficial cutaneous infection, externalized defibrillator leads, and hemoptysis. Bronchoscopical investigation proved the existenc...

We report a case of posttuberculosis (TB) tracheobronchial stenoses presented with progressive exertional dyspnea during the course of anti-TB treatment. An 83-year-old Japanese man was admitted for progressive dyspnea; chest X-ray and CT showed stenosis of distal trachea and left main bronchus. Pulmonary function test revealed reduction of FEV1. Balloon dilatation without stent insertion was t...

The main aim of this work is the study of different pulseshapes for selective small fiber diameter activation in order to minimize charge injection when using the anodal block technique.

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.
