BACKGROUND The purpose of this study was to evaluate the differences in clinical characteristics and treatment outcomes between older and younger tuberculosis (TB) patients in Korea. METHODS We retrospectively analyzed the medical records of 271 younger (20-64 years old at diagnosis) and 199 older (≥65 years) TB patients who had been newly diagnosed and(More)
SETTING Breast tuberculosis (TB) is rare even in endemic areas. Its presentation is variable and non-specific, and its diagnosis is therefore usually delayed. DESIGN We recruited breast TB cases between 1998 and June 2009 at Kaohsiung Medical Center in southern Taiwan. We retrospectively reviewed the clinical features, diagnosis and management of breast(More)
BACKGROUND AND OBJECTIVE Invariant natural killer T (iNKT) cells may play an important role in regulating the innate and acquired immune systems in chronic obstructive pulmonary disease (COPD). However, there is little information regarding the potential role of iNKT cells in the pathogenesis of COPD. To investigate whether iNKT cells have an important role(More)
This investigation experimentally demonstrates the dynamic characteristics of quantum dot vertical-cavity surface-emitting lasers (QD VCSEL) without and with light injection. The QD VCSEL is fully doped structure on GaAs substrate and operates in the 1.3 mum optical communication wavelength. The eye diagram, frequency response, and intermodulation(More)
Cell-cell adhesion is essential for many immunological functions and is believed to be important in the regulation of hematopoiesis. Adhesive interactions between human endothelial cells and megakaryocytes were characterized in vitro using the CMK megakaryocytic cell line as well as marrow megakaryocytes. Although there was no adhesion between unactivated(More)
BACKGROUND This study evaluates the bacterial pathogens of Ventilator-associated pneumonia (VAP) in a tertiary referral hospital. METHODS A total of 109 bacterial pathogens from 91 adult patients with VAP, who were admitted to the medical intensive care unit from January 2008 to December 2009, were examined. Clinical characteristics, bacterial pathogens,(More)
The role of the peroxisome proliferator-activated receptor alpha (PPARalpha) in regulating hepatitis B virus (HBV) transcription and replication in vivo was investigated in an HBV transgenic mouse model. Treatment of HBV transgenic mice with the peroxisome proliferators Wy-14,643 and clofibric acid resulted in a less than twofold increase in HBV(More)
Pulmonary hypertension is a frequent complication of chronic obstructive pulmonary disease (COPD) and associated with a worse survival and increased risk of hospitalization for exacerbation of COPD. However, little information exists regarding the potential role of systemic inflammation in pulmonary hypertension of COPD. The purpose of the present study was(More)
BACKGROUND/AIMS The frequency of nontuberculous mycobacteria pulmonary disease in HIV-negative patients is increasing; the most common pathogen in Korea is the Mycobacterium avium complex (MAC). However, few studies have evaluated the treatment outcome of MAC pulmonary disease in Korea. METHODS The efficacy of a clarithromycin-containing regimen for MAC(More)
Sinus histiocytosis with massive lymphadenopathy (SHML) is a rare disorder characterized by a nonneoplastic proliferation of distinctive histiocyte cells within lymph node sinuses and lymphatics in extranodal sites. SHML occurs worldwide and is primarily a disease of childhood and early adulthood. A 26-yr-old man presented with painless palpable lymph node(More)
