BACKGROUND: Early detection and treatment of cytomegalovirus (CMV) infection is very important because CMN infection is a major cause of morbidity and mortality after organ transplantation. CMV antigenemia assay has been reported to be very sensitive and specific for detection of CMV infection among many laboratory methods. However, there is no single method correlated well with the infection state up to now. We compared the results of SHARP Signal System Assay (Digene, USA) using PCR and hybridization with those of CMV antigenemia assay (Clonab CMV-kit; Biotest AG, Germany) to evaluate their clinical usefulness. METHODS: We performed SHARP Signal Assay on whole blood samples of 125 from 56 transplanted patients submitted for CMV antigenemia at Samsung Medical Center. We compared the results with those of CMV antigenemia and evaluated the correlation with CMV disease state. RESULTS: Fifty six patients were classified as three groups; 43 patients with no evidence of CMV infection, four patients with CMV infection and 9 patients with CMV disease. Twenty four cases (19.2%) showed discrepant results between the two methods. Of the 22 cases showing positive only by SHARP Signal Assay, two cases were proved to be CMV disease, 12 cases were on antiviral treatment and remaining cases had no evidence of infection. Two cases showing positive only by CMV antigenemia were confirmed to be CMV disease. For CMV disease, the sensitivity of SHARP Signal Assay and CMV antigenemia were 85.7% and 90.5%, respectively and the specificity of them were 73.1% and 93.3%, respectively. CONCLUSIONS: CMV antigenemia is thought to be useful for early diagnosis and follow-up of antiviral treatment as a quantitative and highly specific method, and SHARP Signal Assay can be used as a complementary method because it correlates well with disease state.

Seventeen patients with classical rheumatoid arthritis have been treated with gold sodium thiomalate(G.S.T) injection and followed up for 1.7 years on average. The results obtained are as follows: 1. Clinical improvement was obtained in 12(70.3%) out of 17 cases, but only in 5 cases(29.3%) marked and persisting improvement was obtained. Such improvement was first noticed when the total dose of the gold sodium thiomalate reached 500mg or more, and also noticed about 10 weeks after initiation of G.S.T therapy. 2. Changes in laboratory parameters such as hemoglobin, hematocrit, eosinophilia, titers of rheumatoid factor and C-reactive protein, and proteinuria began to appear at the time of the clinical improvement. 3. Adverse reaction consisted mostly of mucocutaneous lesions. The main causes of drop-out during therapy also are severe skin rashes and pruritus. Most of the adverse reactions appeared when the total dose of G.S.T. administered reached over 500mg. In two severe cases skin rashes terminated the gold therapy. Our findings suggest, because of high incidence of adverse reaction during G.S.T therapy, repeated careful clinical and laboratory examination of the patient are mandatory especially when the total dose of G.S.T is reached 500mg. In spite of the well documented reports of the maintenance gold therapy for rheumatoid arthritis it is felt that the maintenance gold therapy should be studied further before it can be safely used as a routine in daily rheumatology practice because of its toxicity.

BACKGROUND: Coagulase negative staphylococcus (CNS) spp. is a major pathogenic organism of nosocomial and community-acquired urianry tract infections, and causes infrctions in the immunocompromised host, and in particular, bloodstream infetions in patent with indwelling devices. High prevalance of methicillin resistance has been noticed in CNS which also have been recongnized as an important multidrug resistant pathogen. The optimal phenotypic method for detecting methicillin resistance still remains controversial, and new guidelines for detecting methicillin resistance of CNS was proposed by NCCLS in January 1999. We evaluated the relationship between mecA gene by PCR method and antimicrobial susceptibility tests according to the new NCCLS guidelines. METHODS: A total of 82 CNS isolates were examined for MICs and penicillin MICs by disk diffusion and agar dilution method according to NCCLS guidelines, and detections, and detection of mecA gene by PCR. RESULT: In disk diffusion method, 66 strains (80.5%) and 63 strains (76.8%) showed resistance to penicillin and oxacillin, respectively, and in agar dilution method, 71 strains(86.6%) and 53 strains (64.6%), respectively. In PCR method, mecA genes were detected in 49 strains(59.8%). Comparing with mecA gene detection by PCR method, the sensitivity of disk diffusion and agar dilution method was 95.8% and 89.8%, repectively. However, the sensitivity of disk diffusion and agar dilution method was 65.3% and 75.5%, respectively using previous NCCLS criteria. CONCLUSION: The new criteria of NCCLS detects the methicillin resistance induced by mecA gene more sensitively than previous one.

PURPOSE: This study was conducted to analyze industrial workers' stresses from physical symptoms, PWI, JCQ and tasks in classification of Sasang constitutions. METHOD: Data were collected from industrial workers in J Province from May 2003 to June 2003. Questionnaires were distributed and collected on the day of their physical examination. Collected data were analysed through chi2-test. RESULT: Health-related characteristics showed that most of smokers and drinkers were Taeumins and this result was statistically significant. Physical symptoms related to constitutions indicated that GI and neurologic symptoms are significantly more frequent in Soeumin. The percentage of subjects with moderate risk was high in order of Soyangin, Taeumin and Soeumin while the percentage of subjects with high risk was high in order of Soeumin, Taeumin and Soyangin. CONCLUSION: Through this study, Lee Jae Ma's theory was be confirmed compatible with disease characteristics. However, research with more various subjects and variables needs to be made.

Paroxymal nocturnal hemoglobinuria is a kind of intravascular hemolytic anemia due to acquired corpscular defects, and is not rare in this country. The corpscular defect is originated from hematopoietic stem cells, and white blood cells and platelets are also involved. Consequently, the major complications which might affect mortality and morbidity include thrombotic phenomena, especially hepatic and cerebral venous thrombosis. This is a case report of cerebral venous thrombosis with hemiparesis, seizure and change of consciousness in paroxysmal nocturnal hemoglobinuria accompanied by intravascular hemolysis. The diagnosis is confirmed by CT brain scan and cerebral angiography and the patient is effectively treated with antiplatelets, anticonvulsants and steroids.

Anthracycline drugs are chemotherapeutic agents highly effective against a wide range of neoplasms. However, its administration may be complicated by cardiotoxic reactions. There is a continuum of increasing risk with increasing total dose of drug rather than an absolute cutoff point for total dose drug of that should not be exceeded under any circumstances. At the present time it appears that a potentially important clinical application of Doppler echocardiography would be the noninvasive evaluation of global ventricular function. To assess the value of serial Doppler echocardiography in detecting early signs of anthracycline cardiotoxicity in children, we studied 50 patients (35 male and 15 female children, age range 1.6 to 20 years) admitted to the Department of Pediatrics in the Kyungpook National University Hospital for treatment of neoplasia between July 20, 1988 and April 20, 1991 prospectively. Eight three Doppler echocardiograms were performed prior to and at intervals after receiving varying doses of anthracycline and aortic velocity, acceleration time (AT), ejection time (ET), ratio at AT to ET (AT/ET), acceleration and velocity time integral, and mitral velocity of E and A waves and velocity time integral were measured. Pretreatment parameters were not differ from those of normal age matched control children. The aortic AT/ET showed significant increase with increase in anthracycline dosage, being a mean (+/-SD) of 0.30+/-0.07 in the pretreatment group, 0.33 (+/-0.09) after 100 mg/M2 (p<0.001) but the mitral E/A peak velocity ratio showed significant decrease, being a mean (+/-SD) of 1.47 (+/-0.26) in the pretreatment group and 1.36 (+/-0.09) after 400mg/M2(p<0.05). We could not reliably ascertain the relationship between Doppler echocardiographic changes and development of anthracycline cardiomyopathy but these preliminary data show that Doppler echocardiography may detect incremental changes in left ventricular function in anthracycline cardiomyopathy. It is hoped that further study at higher dose levels in large populations for a sufficient follow up time will identify those patients with a risk of developing cardiomyopathy and then manage them appropriately.
