PURPOSE: Conventional indomethacin therapy(0.2mg/kg every 12 hours for three doses) has been used for closure of PDA. The effect of prolonged low dose of indomethacin therapy(0.1mg/kg daily for six days)had been reported in foreign country but, nothing had been reported in our country. So we attempted this study to examine effects of these two methods. METHODS: Forty one infants with PDA of prematurity from January 1992 to July 1995 who were admitted in NICU of Il Sin Christian Hospital were included. 27 of these infants received conventional dose of indomethacin therapy and 14 received prolonged low dose of indomethacin therapy, and we examined with closure rate and complication etc. RESULTS: 1) Closure of PDA was observed in 15(55.6%) and relapse was 3(11.1%) in conventional dose therapy group. In prolonged low dose therapy group, closure was 8(57.1%) and relapse was none. 2) Intraventricular hemorrhage was observed in 20(74.1%), 6(42.9%) and gastrointestinal tract bleeding was 6(22.2%), 13(92.2%) in each group. There was statistically significant between the two groups(p<0.05). 3) The rise of serum BUN, creatinine was observed in 9(33.3%), 6(46.2%), bleeding tendency was 9(33.3%), 8(57.1%), necrotizing enterocolitis was 2(7.4%), 0 and retinopathy of prematurity was 8(29.6%), 3(21.4%) in each group.But there was not statistically significant correlation between the two groups. 4) The development of sepsis and broncopulmonary dysplasia was slightly more in prolonged low dose therapy group. 5) The reduction of urine output was observed in 11(40.7%), 2(14.3%) in each group but, absolute oliguria was not observed in both groups. CONCLUSIONS: Though the closure rate of PDA was similar in both groups, prolonged low dose indomethacin therapy can be recommanded with its effectiveness on preventing the relapse of PDA and the accurrence of necrotizing enterocolitis.

Although digital gangrene is an uncommon clinical feature, it may lead to serious complications, such as amputation. Therefore, it requires prompt evaluation and treatment. Digital gangrene is often seen in systemic sclerosis, but is rare in systemic lupus erythematosus (SLE). In SLE, digital gangrene results from vasculitis, vasospasm, and thromboembolism. Here, we report a 15-year-old male SLE patient who initially presented with digital gangrene, and present a review of the relevant literature.

Neck pain is a common musculoskeletal condition, which causes substantial medical cost. In Korea, prevalence of neck pain in community based population, especially in elderly subjects, has scarcely been reported. We evaluated the prevalence, the severity and the risk factors of neck pain in elderly Korean community residents. Data for neck pain were collected for 1,655 subjects from a rural farming community. The point, 6-months and cumulative lifetime prevalence of neck pain was obtained in addition to the measurement of the severity of neck pain. The mean age of the study subjects was 61 yr and 57% were females. The lifetime prevalence of neck pain was 20.8% with women having a higher prevalence. The prevalence did not increase with age, and the majority of individuals had low-intensity/low-disability pain. Subjects with neck pain had a significantly worse SF-12 score in all domains except for mental health. The prevalence of neck pain was significantly associated with female gender, obesity and smoking. This is the first large-scale Korean study estimating the prevalence of neck pain in elderly population. Although the majority of individuals had low-intensity/low-disability pain, subjects with neck pain had a significantly worse SF-12 score indicating that neck pain has significant health impact.

Epstein-Barr virus (EBV)-encoded small non-coding RNAs (EBERs) are abundantly expressed in various EBV-associated malignancies, and play critical roles in cell proliferation, tumorigenesis, and apoptosis resistance. However, the mechanism how EBERs regulate cell function awaits further clarification. In this study, we investigated the effect of EBERs on the expression of cellular microRNA (miRNA) and mRNA expression. To test the effect of EBERs while unaffected by other EBV genes, we used EBERs-deleted recombinant EBV infected Burkitt's lymphoma cell line (Akata(+)EBERs(-)) as well as EBV-infected (Akata(+)) and EBV uninfected (Akata(-)) cell lines. They all have the same genetic backgrounds. First, 15 different cellular miRNAs which have reverse complementary sequences to EBERs and have reported targets were selected by bioinformatics analysis. When RT-PCR was carried out for the 16 miRNAs using RNAs from Akata(+), Akata(-), and Akata(+)EBERs(-) cells, hsa-miR-7-5p was the only one showing down-regulated expression in Akata(+) than in Akata(-) and Akata(+)EBERs(-) cells. Bioinformatics and mRNA microarray analyses for Akata(+), Akata(-), and Akata(+)EBERs(-) cell lines were then carried out to predict putative targets of hsa-miR-7-5p. Among the 6 predicted targets of hsa-miR-7-5p, only low density lipoprotein receptor-related protein 6 (LRP6) was up-regulated in EBERs-expressing cells when tested by RT-PCR and Western blot. However, luciferase reporter assay showed that the 3'-UTR of LRP6 was not directly targeted by hsa-miR-7-5p. Our data suggest that both hsa-miR-7-5p and LRP6 are regulated by EBERs in Akata cells, and these genes may partly mediate the tumorigenic function of EBERs in Burkitt's lymphoma.

OBJECTIVES: To assess the relationship between ST segment elevation during exercise testing and coronary artery disease. METHODS: Treadmill exercise electrocardiography and coronary angiography were performed in 137 patients with angina with no Q waves. The J point elevation of > 0.03mV(0.3mm) measured from baseline, the elevation of ST segment at 80msec. from J point(ST80) measured larger in lead V1than in aV1, or both the elevation of ST segment at J point and at ST80 developed earlier than or concomitantly with ST depression were considered as abnormal responses. RESULTS: 1) There was no clinical significance of ST elevation in lead aV1. 2) Exercise-induced ST elevation in lead V1occurred in 29 of 137 patients with angina. 3) Abnormal St elevation in V1was detected in 26 of 86 patients with coronary artery disease, for a specificity of 98%. The patients with left anterior descending coronary artery or left main coronary artery stenosis were observed in 3 of 5(60%) patients with single-vessel disease, in 7 of 9(79%) with two-vessel disease, and in 9 of 10(90%) with three-vessel disease. 4) The standard ST depression yielded a specificity of 55% in the patients with isolated or predominant ST depression in inferior leads(II. III, and aVF) and of 81% in the patients with isolated or predominat ST depressin in precordial leads(p<0.001). 5) Abnormal exercise-induced ST elevation in V1was detected in 13 of 39(33%) patients with isolated or predominat ST depression in inferior leads and yielded a specificity of 94% for coronary artery disease. CONCLUSION: Abnormal ST segment elevation in V1may increase the specificity in isolated or predominat ST segment depression in inferior leads and may predict left anterior descending or left main coronary artery disease.

We describe a cutaneous abscess caused by Nocardia abscessus in a previously healthy woman. A 74-year-old woman presented with recurrent bullae on her left forearm that developed 1 week prior and was initially suspected to be a cutaneous infection with Mycobacteria or Tinea corporis. Histopathologically, the skin lesion formed an abscess. A smear revealed a few branched Gram-positive filamentous microorganisms that formed a creamy white colony on a blood agar plate after incubation for 3 days. The colony tested negative on acid-fast bacilli (AFB) staining, but was positive on modified AFB staining. The isolate was confirmed to be N. abscessus by 16S rRNA sequencing analysis. The isolate was susceptible to trimethoprim-sulfamethoxazole, amikacin, cefotaxime and erythromycin but resistant to penicillin. The patient was treated with clarithromycin but subsequently lost to follow-up. To the best of our knowledge, this is the first report of a human cutaneous infection with N. abscessus in Korea.

The Korean Journal of Internal Medicine 2021;36(1):214-222
Background/Aims:
To explore the associations between body composition and pain, disease activity, and disability in rheumatoid arthritis (RA).
Methods:
The study enrolled 335 patients with RA and underwent body composition measurement with an InBody analyzer. The associations of body mass index (BMI), body fat mass, and skeletal muscle mass with disease activity score in 28 joints (DAS28), an index derived to measure the subjective component of DAS28 (DAS28-P), a pain visual analogue scale (VAS), and disability measured with the health assessment questionnaire (HAQ) were explored. Obesity was defined as BMI ≥ 25 kg/m2
Results:
The median (interquartile range) disease duration was 6 years (3.5 to 9) and the mean DAS28 score was 3.6 ± 1.1. The mean BMI was 23.6 ± 3.6 kg/m2 and 109 patients (32.5%) were obese. Compared with non-obese patients, obese patients had a higher C-reactive protein (1.68 mg/dL vs. < 0.1 mg/dL, p = 0.013), higher pain VAS score (40 vs. 35, p = 0.031), and higher DAS28-erythrocyte sedimentation rate score (3.75 ± 1.18 vs. 3.46 ± 1.11, p = 0.031). In multivariate regression analysis, the DAS28 score in females was positively associated with the current steroid dose, body fat mass, and HAQ score, while the HAQ score in females was associated with older age, DAS28, lower skeletal muscle mass, and higher body fat/skeletal muscle ratio. In the multivariate regression analysis, the DAS28-P score in females was positively associated with body fat/skeletal muscle ratio and HAQ.
Conclusions
Body composition, such as the body fat mass and body fat/skeletal muscle ratio, is significantly associated with disease activity and disability in female RA patients.

Background/Aims:
We examined temporal trends in the rate of gout and seropositive rheumatoid arthritis (RA) hospital visits and healthcare costs in Korea.
Methods:
We conducted a serial cross-sectional analysis of Korean national healthcare claims. We calculated the annual increase in hospital visits (emergency department [ED] visits, outpatient visits, and hospitalizations) and total healthcare costs per visit.
Results:
From 2010 to 2017, the annual rates of ED visits, outpatient visits, and hospitalizations for gout increased from 6.28 to 21, from 638.38 to 1059.55, and from 12.37 to 15.6 per 100,000 persons, respectively. Before 2013, ED visits for gout were most common in patients over 70 years old, but they were most common in those aged between 30 and 49 years after 2013. The number of patients with ED visits, outpatient visits, and hospitalizations for RA from 2010 to 2017 increased from 1.25 to 1.87, from 219.04 to 307.49 and from 8.44 to 12.32 per 100,000 persons, respectively. However, there was no increase in the prevalence of ED visits for RA in any age group except for those older than 70 years. The cost per ED visit for gout significantly decreased from 496.3 to 273.6 US dollar during the study period. There was no significant change in the cost per ED visit for RA between 2010 and 2017.
Conclusions
There was a large increase in ED visits for gout during the study period. Further studies are needed to analyze the reason behind increased ED visits for gout and suggest ways on how to improve gout care.

BACKGROUND/AIMS: Biological agents (biologics) targeting proinflammatory signaling have emerged as an important treatment option in rheumatoid arthritis (RA). Despite the clinical effectiveness of biologics for patients with RA who do not respond to ‘traditional’ disease-modifying anti-rheumatic drugs (DMARDs), there are concerns regarding their cost and long-term safety. In this study, we aimed to compare the efficacy of various biologics and traditional DMARDs in RA patients refractory to methotrexate (MTX). METHODS: Four DMARDs (hydroxychloroquine, sulfasalazine, MTX, leflunomide) and five anti-tumor necrosis factor drugs (adalimumab, etanercept, golimumab, infliximab, and certolizumab) were selected. A systematic search of published studies was performed from inception through July 2013. Randomized trials of adults with MTX-refractory RA comparing two or more of the selected medications were included. Among 7,938 titles identified, in total, 16 head-to-head trials were selected. Two reviewers independently abstracted the study data and assessed methodological quality using the Cochrane Risk of Bias. Comparative efficacy was analyzed using a Bayesian mixed treatment comparison (MTC). RESULTS: In total, 9, 4, and 11 studies were included for the outcome measures of the Health Assessment Questionnaire (HAQ), Disease Activity Score 28-erythrocyte sedimentation rate (DAS28-ESR) < 2.6 (remission), and American College of Rheumatology (ACR) 70 response, respectively. The treatments with the highest efficacy for each outcome measure were certolizumab combined with MTX, golimumab combined with MTX, and certolizumab combined with MTX, respectively. CONCLUSIONS: Based on MTC analysis, using data from published randomized controlled trials, certolizumab and golimumab combined with MTX showed the highest efficacy in the three outcome measures (HAQ, DAS28-ESR < 2.6, and ACR 70 response) in MTX-refractory RA patients.
