PURPOSE The purpose of the study was to determine whether earlier clinical intervention by a medical emergency team (MET) can improve patient outcomes in an Asian country. METHODS A nonrandomized study was performed during two 6-month periods before and after the introduction of a MET. RESULTS The rates of cardiac arrests and "potentially preventable"(More)
BACKGROUND Adenoid cystic carcinoma (ACC) of the airway is a slowly growing tumor and airway narrowing is one of the main causes of death. The purposes of this study were to investigate treatment outcomes, prognostic factors, and the indications and outcomes of bronchoscopic interventions in patients with ACC of the airway. METHODS We retrospectively(More)
BACKGROUND Incidental thyroid nodules (ITNs) are defined as newly encountered nodules identified on imaging performed for an unrelated purpose. In practice, ITNs are often detected on chest computed tomography (CT). We investigated the prevalence and clinical significance of ITNs detected on low-dose chest CT (LDCT) for lung cancer screening. METHODS We(More)
Although blood cultures (BCs) are an important component of diagnostic practice for antibiotic management in patients with pneumonia, several studies have questioned whether they should be performed. The objective of this study was to evaluate the predictive factors of bacteremia and the role of BCs in patients with community-onset pneumonia(More)
BACKGROUND The increasing number of outpatients with multidrug-resistant (MDR) pathogens has led to a new category of pneumonia, termed healthcare-associated pneumonia (HCAP). We determined the differences in etiology and outcomes between patients with HCAP and those with community-acquired pneumonia (CAP) to clarify the risk factors for HCAP mortality. (More)
INTRODUCTION The development of synchronous multiple primary non-small cell lung cancer (NSCLC) is not rare. Nevertheless, the diagnosis, treatment and outcome are controversial. The purposes of this study were to assess the treatment outcomes for patients with synchronous multiple primary NSCLC and to analyze the factors related to this outcome. METHODS(More)
Although diffuse alveolar hemorrhage complicating warfarin therapy is rare, it generally has a worsening clinical course and can be a life threatening condition. A 56-year-old male who had undergone a pulmonary lobectomy for lung cancer 2 years before had received warfarin for about 5 months due to pulmonary vein thrombosis. The patient presented with(More)
Hemobilia is a hemorrhage into the biliary tract that may follow surgical trauma, liver biopsy, aneurysms, extra- or intra-hepatic tumors of the biliary tract, gallstones, and inflammatory lesion of liver, especially helminthic or pyogenic. Sometimes, it is associated with primary liver cancer. An 84 year-old woman was admitted because of continuous right(More)
BACKGROUND Mycobacterial identification in active pulmonary tuberculosis (APTB) is confirmative, even though successful rates using self-expectorated sputum are limited. Sputum specimens collected by hypertonic saline nebulization showed higher bacteriologic diagnostic sensitivities over those of self-expectoration, mostly studied in smear-negative or(More)
BACKGROUND Pyrazinamide (PZA) is an effective antitubercular drug that becomes toxic to Mycobacterium tuberculosis when converted to pyrazinoic acid by pyrazinamidase (PZase), encoded by mycobacterial pncA. A strong association was noted between the loss of PZase activity and PZA resistance. The causative organisms in extrapulmonary tuberculosis are rarely(More)
