Pyrazinamide (PZA) is one of the most important drugs for the treatment of Mycobacterium tuberculosis infection. However, the increasing frequency of PZA-resistant strains limits its effectiveness. In Korea, most PZA-resistant strains also exhibit both isoniazid and rifampin resistance making it essential to identify these resistant strains accurately and rapidly for effective treatment of mycobacterial infection. In this study, the characteristics and frequency of mutations of the pncA gene enc

(18)F-FDG uptake calculated by the Tmax/Lmean using PET predicted tumor progression and survival in patients with BCLC intermediate-stage HCC treated by TACE.

Mucolipidosis II (ML II) or inclusion cell disease (I-cell disease) is a rarely occurring autosomal recessive lysosomal enzyme-targeting disease. This disease is usually found to occur in individuals aged between 6 and 12 months, with a clinical phenotype resembling that of Hurler syndrome and radiological findings resembling those of dysostosis multiplex. However, we encountered a rare case of an infant with ML II who presented with prenatal skeletal dysplasia and typical clinical features of s

Purpose: To evaluate the efficacy, safety, predictability and subjective symptoms of the implantable contact lens to treat moderate to high myopia. Methods: A Staar Collamer posterior chamber phakic IOL was implanted in 83 eyes of 44 patients with spherical equivalent -10.10D (-3.87-19.37D). Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction, adverse events, subjective quality of vision and satisfaction were evaluated. Mean follow-up was 4.9 months (39 months). Res

The artificial blockade of the portosystemic shunt evidently leads to an increase in HVPG. Liver function was improved over the 6-month follow-up period. Portal pressure after PARTO was a significant risk factor for EV deterioration. Portal pressure measurement is helpful for predicting the patient's clinical outcome.

The Flexivue Microlens refractive corneal inlay was effective for improving near visual acuity at 6 months follow-up But proportion of spectacle independency and patient satisfaction were lower in this Korean population than in previous reports. Further study with a longer follow-up period is needed.

Background The incidence of penicillin-resistant streptococcus pneumoniae(PRSP) accounts for almost 70% of all pneumococcal pneumonia cases in Korea. It is still unclear as to whether the efficacy of penicillin or equally active beta-lactam agents is compromised in PRSP pneumonia. This study investigated the prevalence of PRSP in community-acquired pneumonia and its clinical course. Methods A total of 42 patients with community-acquired pneumococcal pneumonia were evaluated from July 1999 to May

Background Recent technological developments have introduced a new method to identifying M. tuberculosis complex DNA in clinical samples directly. The direct amplification test (DAT) is approved for identifying M. tuberculosis complex in respiratory specimens that are smear-positive for acid-fast bacilli (AFB). When there is a discrepancy between the AFB smear and DAT, no information on their clinical utility is currently available. In this study, the diagnostic reliability of DAT was investigat

Purpose To evaluate clinical outcomes of transarterial embolization of bilateral uterine arteries (UAE) in patients with acquired uterine vascular malformation (UVM). Materials and Methods This retrospective study was performed on the medical records of all 19 patients who underwent transarterial embolization of bilateral UAE for the treatment of symptomatic UVMs from January 2003 to June 2011. Embolization was performed via the unilateral femoral artery approach with a catheter and angiographic

Purpose: To evaluate the effects of ICL implantation on angle structures, intraocular pressure (IOP) and pupil diameter. Methods: A Staar implantable contact lens (ICL) was implanted in 81 eyes of 43 patients with spherical equivalent over -6D. Gonioscopy was done 1 day after laser iridotomy and 6 months after ICL implantation and postoperative changes in gonioscopic findings were evaluated. Also IOP and pupil diameter were examined. Results: There were occlusion or narrowing of the LI opening s

Although HT for HCC tends to increase intermediate-dose spillage, the treatment results were favorable with that reported in other published studies.

Background: The aim of this study is to evaluate the usefulness of quantitative culture of bronchoalveolar lavage (BAL) fluid for the diagnosis of bacterial pneumonia and identification of causative agents. Methods: Study group consisted of 30 epiaodes in 28 patients, enrolled from January 1995 through June 1996. Inclusion criteria were 1) presence of respiratory symptoms such as cough, sputum or dyspnea 2) increased peripheral blood leukocyte count (≥11,000/mm³) 3) Fever (≥38.3oC) 4) purulent s

Background Many studies have shown that pulmonary function differs widely among race, age and geographical residency. By virtue of the improvement of nutrition and environment, the elderly population in Korea is markedly increasing and so are the ages of patients complaining respiratory symptoms. However, we do not have our own data on the pulmonary functional reserve of elderly persons in Korea. We evaluate the deterioration of pulmonary functional reserve and standardize the predictive values
