OBJECTIVE To identify patient-related and device-specific predictors of challenging and failed inferior vena cava (IVC) filter retrievals. METHODS Retrospective single center review of consecutive retrievable IVC filters placed between 2004 and 2009. Retrieval was defined as challenging when it was unsuccessful owing to reported technical failure or when(More)
BACKGROUND Mediastinitis remains a life-threatening disease that is difficult to manage and has a poor prognosis. This is especially true of descending necrotizing mediastinitis, which before the 1990s era had a mortality of approximately 40% despite the use of antibiotics, surgical techniques, and intensive care monitoring. Several authors have recommended(More)
BACKGROUND Preoperative localization with lipiodol for identifying small or deeply seated pulmonary nodules is simple and useful for thoracoscopic surgery. Although several studies about performance and complication rates of lipiodol localization have been reported, there has been no report about the performance and complication rates of lipiodol(More)
Pyrazinamide has played a critical role in shortening therapy against drug-sensitive, drug-resistant, active, and latent tuberculosis (TB). Despite widespread recognition of its therapeutic importance, the sterilizing properties of this 60-year-old drug remain an enigma given its rather poor activity in vitro. Here we revisit longstanding paradigms and(More)
BACKGROUND Thoracoscopic wedge resection is generally accepted as a standard surgical procedure for primary spontaneous pneumothorax. Because of the relatively high recurrence rate after surgery, additional procedures such as mechanical pleurodesis or visceral pleural coverage are usually applied to minimize recurrence, although mechanical pleurodesis has(More)
Finding new treatment-shortening antibiotics to improve cure rates and curb the alarming emergence of drug resistance is the major objective of tuberculosis (TB) drug development. Using a matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging suite in a biosafety containment facility, we show that the key sterilizing drugs rifampicin(More)
BACKGROUND Early diagnosis and appropriate treatment are important for a good outcome in Boerhaave's syndrome. The results of recent studies suggest that primary esophageal repair should be performed for perforations, and some authors suggest that there are benefits from thoracoscopic surgery in cases that are diagnosed early. METHODS From December 2004(More)
BACKGROUND Interferon-γ release assays (IGRAs) have been incorporated into several national guidelines for latent TB infection (LTBI) diagnosis. However, their optimal application is still controversial and evolving. The aim of this study is to evaluate the performance of confirmatory IGRAs in addition to tuberculin skin tests (TSTs) in high school students(More)
OBJECTIVE To evaluate the clinical efficacy of pulmonary resection and postoperative use of a first-line drug regimen for patients with well-localized, cavitary pulmonary multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB). METHODS This was a prospective case study set in the National Masan Tuberculosis Hospital(More)
BACKGROUND The standard operative treatment of primary spontaneous pneumothorax (PSP) is thoracoscopic wedge resection, but necessity of pleurodesis still remains controversial. Nevertheless, pleural procedure after wedge resection such as pleurodesis has been performed in some patients who need an extremely low recurrence rate. MATERIALS AND METHODS From(More)
