We have submitted and published the above paper in Infection and Chemotherapy in 2003. Another paper with a condensed but almost same content as the above paper was submitted to and published in an English journal (Acute Hemorrhagic Conjunctivitis Caused by Coxsackievirus A24 Variant, South Korea, 2002. Emerg Infect Dis 2003). Our original intent was to introduce the study to all readers because the two journals seemed to cover different spectrum of readers. However, we did not follow the necessary steps for secondary publication. So we are asking the permission of the Editor to retract the above paper. We hereby regret to have to retract the paper.

Nontuberculous mycobacteria are ubiquitous organisms that are frequently present in the water, soil and animal reservoirs. Nontuberculous mycobacterial infections of the musculoskeletal system are rare and usually associated with predisposing factors, such as prior joint disease, trauma, use of intraarticular or oral corticosteroids, or an immunocompromised state. A sixty five-year-old patient with rheumatoid arthritis was hospitalized due to swelling on the left wrist. M. intracellulare was cultured from the aspirated joint fluid. The patient was successfully treated with clarithromycin, ethambutol, and rifampin. We report this case with review, emphasizing high suspicion for nontuberculous mycobacterial infection in patients with predisposing risk factors.

Spontaneous bacterial peritonitis is the common infectious disease in liver cirrhosis patients with a fever. Brucellosis is a rare cause of bacterial peritonitis. A case indigenous to a citizen of Jeju, he ate a raw veal of cow four times in last 2 months prior to admission. The gram-negative bacilli were isolated from blood and peritoneal fluid cultures. He was confirmed brucellosis by serologic work- ups. This isolate was confirmed as Brucella abortus by using PCR amplification of 16S ribosomal RNA (rRNA) and omp2. This is the first case of bruellosis that was diagnosed spontaneous bacterial peritonitis in liver cirrhosis patient among native korean citizens. Successful treatment was obtained by using a regimen of doxycycline and gentamicin. Brucella should be suspected as a cause of spontaneous bacterial peritonitis in cirrhotic patients with no response to standard spontaneous bacterial peritonitis treatments.

Infectious diseases imported from other countries have increased as more and more Koreans are going abroad for various purposes. Tsutsugamushi disease from other endemic area such as Southeast Asia is important, because it can occur in any season and eschar may be absent. We report a case of imported tsutsugamushi disease acquired in the Philippines. A patient presented with fever, headache, and maculopapular skin rash. However, eschar was absent. Polymerase chain reaction (PCR) for 56-kDa gene of Orientia tsutsugamushi using buffy coat was positive. Serum indirect immunofluorescent antibody assay was initially negative but became positive with a titer of 1:320 at follow-up. Sequencing analysis revealed the strain to be 100% identical to the TW73R strain identified in Taiwan. After the patient received doxycycline, body temperature normalized in 12 hours. Tsutsugamushi disease is one of the differential diagnoses that should be included for patients with fever who have recently returned from Southeast Asian countries. PCR for O. tsutsugamushi using patient's buffy coat was useful for early diagnosis.

Serratia marcescens causes various diseases. Skin ulcer is one of S. marcescens related diseases, but it is rare clinical syndrome. We experienced a case of skin ulcer caused by S. marcescens in a woman with alcohol induced cirrhosis. After exposure to fresh water while trimming the codfish, she developed deep ulcer on her right hand and bacteremia by S. marcescens. S. marcescens should be considered as a specific etiology of skin infection presenting after fresh water exposure.

Stevens-Johnson syndrome is an acute mucocutaneous syndrome that is related to drugs and infections. Mycoplasma pneumoniae infection is known as one of the causes of Stevens-Johnson syndrome in children and young adults. In Korea, Mycoplasma pneumoniae infection is rarely reported as a cause of Stevens-Johnson syndrome in adults. We report a case of Stevens-Johnson syndrome associated with Mycoplasma pneumoniae pneumonia in an adult patient. A 34-years old woman was admitted to our hospital and was diagnosed with mycoplasma pneumonia. At the time of admission, she had hemorrhagic crusts on her lips. On the 2nd day of admission, target lesions also developed on her skin. We diagnosed her disease as Stevens-Johnson syndrome associated with Mycoplasma pneumoniae pneumonia. She completely recovered from pneumonia and Stevens-Johnson syndrome after treatment with antibiotics and conservative management.

Disseminated tuberculosis occurs through lymphohematogenous dissemination of Mycobacterium tuberculosis bacilli. The exact incidence of disseminated tuberculosis is still unknown and its diagnosis presents a challenge since the symptoms are not specific of the disease. Brain tuberculoma is one of the complications of tuberculosis. The literary review of brain tuberculoma shows that it mainly occurs in the cerebrum and cerebellum, whereas involvement of the brainstem is rare. Recently, we have experienced a case of 46-year-old man with fever of 2 months duration who was diagnosed with disseminated tuberculosis with miliary central nervous system (CNS) tuberculomas; brain tuberculomas were found even in the brainstem and the spinal cord. Pulmonary, intestinal, renal, and choroidal involvements were also noted.

BACKGROUND: To evaluate whether Staphylococcus aureus is actually the leading cause of infective endocarditis in Korea, investigation on updated clinical pictures, treatments, and prognosis was performed. This study also aims to describe differences in clinical characteristics of infective endocarditis in patients undergoing maintenance hemodialysis. MATERIALS AND METHODS: Fifty five patients who were diagnosed with infective endocarditis, using modified Duke criteria, at 4 Soon Chun Hyang University Hospitals (located in Seoul, Bucheon, Cheonan, and Gumi) from January of 2000 to June of 2007 were enrolled. Patients were separated into two groups; those on hemodialysis and those who were not on hemodialysis (control group). Medical records and laboratory results of each patient were reviewed retrospectively. RESULTS: The positive rate of blood culture was 72.7%. Staphylococcus aureus was isolated in 38.2% of the patients, making it the most common causative organism of infective endocarditis. It was also the most common organism in both hemodialysis group and non-hemodialysis group. Six patients (10.9%) died while admitted to the hospital and the in-hospital death rate for hemodialysis group was significantly higher. CONCLUSION: In most parts of the world, S. aureus is increasingly becoming the principal causative organism of infective endocarditis. To our knowledge, this is the first study that shows S. aureus to be the most common causative organism of infective endocarditis in Korea, and that Korea is not except from this global epidemiology.

BACKGROUND: Occasionally, combinations of antibiotics are used for the treatment of scrub typhus. However, the effectiveness of such combined therapies has rarely been evaluated. To date, no experimental studies have been performed; only 1 clinical study has assessed the efficacy of combined doxycycline and rifampin therapy. To elucidate the efficacies of other antibiotic combinations, we performed an experiment to evaluate the in vitro efficacy of antibiotic combinations against Orientia tsutsugamushi. MATERIALS AND METHODS: O. tsutsugamushi strain Boryong was inoculated into the ECV304 cell line. The infected cells were cultured in antibiotic-containing media for 3-5 days and stained with FS15, a monoclonal antibody reacting against the linear epitope on the 56-kDa major outer membrane protein of O. tsutsugamushi. Thereafter, antimicrobial susceptibility was measured by flow cytometry and expressed as a growth index (total mass of Orientia). The growth indices of doxycycline (0.1 microg/mL), azithromycin (0.1 microg/mL), rifampin (0.0125 microg/mL), cefotaxime (2 and 20 microg/mL), and their various combinations (doxycycline+cefotaxime, doxycycline+rifampin, azithromycin+cefotaxime, and rifampin+cefotaxime) were measured. The above mentioned antibiotic concentrations, except for that of cefotaxime, represent the minimal inhibitory concentrations of each antibiotic. RESULTS: The growth indices of doxycycline (4.67% and 0.52%), rifampin (2.35% and 0.26%), and azithromycin (7.54%) were within the range of full suppression of O. tsutsugamushi; in contrast, cefotaxime (87.60%) was in effective. The growth indices of doxycycline+rifampin were 0.10% and 0.10%, which were similar to those obtained with doxycycline or rifampin alone. The growth indices of doxycycline+cefotaxime were 3.99% and 3.65% in low-dose cefotaxime (2 microg/mL), and 3.69% and 4.40% in high-dose cefotaxime (20 microg/mL). The growth indices of rifampin+cefotaxime (2.19% and 2.19% at 2 microg/mL; 1.84% and 2.04% at 20 microg/mL cefotaxime) were similar to those obtained with rifampin alone (2.35% and 0.26%). Azithromycin+cefotaxime (11.06-14.63%) showed higher growth indices than azithromycin alone; this suggests that this combination may be antagonistic. Conclusions: The anti-Orientia efficacies of doxycycline+rifampin, doxycycline+cefotaxime, and rifampin+cefotaxime were not antagonistic. The efficacy of the azithromycin+cefotaxime combination needs to be confirmed by more sensitive methods to exclude the possibility of antagonistic interactions between the antibiotics.

BACKGROUND: The aim of the present study was to assess the contribution of a QuantiFERON-TB Gold In-Tube test (QFT-IT) in differentiating active tuberculosis (TB) from latent tuberculosis infection (LTBI) by quantifying interferon-gamma levels. MATERIALS AND METHODS: We retrospectively reviewed clinical records of 314 patients older than 15 years who had performed QFT-IT between July 2006 and August 2007 at a tertiary care teaching hospital. RESULTS: Subjects with active TB (n=81, culture confirmed active TB in 40 subjects) and LTBI (n=76) were included. Mean+/-SD IFN-gamma levels were 4.96+/-3.98 IU/mL (range -0.08-10) for all subjects with active TB, 4.54+/-4.05 IU/mL (range -0.08-10) for culture confirmed active TB, and 4.11+/-3.57 IU/mL (range 0.35-10) for subjects with LTBI. The quantitative results of QFT-IT on IFN-gamma levels between all the subjects with active TB and those with LTBI were not statistically significant (P=0.16). The result was similar when compared between those with culture confirmed active TB and those with LTBI, showing little statistical significance (P=0.554). CONCLUSION: The production of IFN-gamma measured by QFT-IT showed no correlation between its level and the activity of Mycobacterium tuberculosis infection. These results suggest that measuring IFN-gamma using QFT-IT might not be useful for distinguishing active TB from LTBI.
