PURPOSE: This study analyzed the prognostic factors affecting admission in acute alcohol-intoxicated traumatic brain injury (TBI) patients visiting the emergency room. METHODS: A multicenter, retrospective observational study was conducted on 821 acute alcohol-intoxicated adult trauma patients, who visited 10 university hospital emergency centers from April to November 2016. The primary outcome was hospital admission. The secondary outcome was in-hospital mortality. RESULTS: One hundred sixty-eight patients diagnosed with acute alcohol-intoxicated TBI were analyzed. The increase in blood alcohol concentration was associated significantly with a mild decrease in admission (adjusted odds ratio, 0.993; 95% confidence interval, 0.989 to 0.998; p=0.01). Moderate to severe TBI patients showed a significant increase in admission compared to mild TBI patients (adjusted odds ratio, 12.449; 95% confidence interval, 3.316 to 46.743; p < 0.001). CONCLUSION: This study showed that the admission was inversely correlated with the blood alcohol concentration and is correlated directly with the increase in the severity in TBI. Therefore, emergency physicians may be required to identify the severity of TBI rapidly and accurately in acute alcohol-intoxicated trauma patients visiting the emergency room.

Hyperlipidemia, which is closely associated with a fatty diet and aging, is commonly observed in the western and aged society. Therefore, a novel therapeutic approach for this disease is critical, and an immunological view has been suggested as a novel strategy, because hyperlipidemia is closely associated with inflammation and immune dysfunction. In this study, the effects of an aqueous extract of Rubus occidentalis (RO) in obese mice were investigated using immunological indexes. The mice were fed a high-fat diet (HFD) to induce hyperlipidemia, which was confirmed by biochemical analysis and examination of the mouse physiology. Two different doses of RO and rosuvastatin, a cholesterol synthesis inhibitor used as a control, were orally administered. Disturbances in immune cellularity as well as lymphocyte proliferation and cytokine production were significantly normalized by oral administration of RO, which also decreased the elevated serum tumor necrosis factor (TNF)-α level and total cholesterol. The specific immune-related actions of RO comprised considerable improvement in cytotoxic T cell killing functions and regulation of antibody production to within the normal range. The immunological evidence confirms the significant cholesterol-lowering effect of RO, suggesting its potential as a novel therapeutic agent for hyperlipidemia and associated immune decline.

OBJECTIVE: The aim of this study was to examine and compare the gastrointestinal (GI) risk factors and treatment patterns of rheumatoid arthritis (RA) and osteoarthritis (OA) patients in Korea. METHODS: This was a cross-sectional, observational study on RA and OA patients taking non-steroidal anti-inflammatory drugs (NSAIDs) for at least 1 month. A total of 1,896 patients (981 RA patients, 915 OA patients) were recruited from 20 university hospitals. Data were collected through medical records and patient surveys. GI risk factors included age, prolonged (over 3 months) or high-dose use of NSAIDs, alcohol drinking, smoking, use of aspirin, anticoagulants or glucocorticoids, comorbidities, and history of Helicobacter pylori infection or other GI complications. Treatment patterns were classified according to groups using, selective cyclooxygenase (COX)-2 inhibitors+/-gastro-protective agents, non-selective COX-2 inhibitors+proton pump inhibitor, or non-selective COX-2 inhibitors+/-other gastro-protective agents. RESULTS: GI risk factors were highly present in both RA and OA patients. The proportion of prolonged use of NSAIDs, smoking, and glucocorticoid use were higher in RA patients (p<0.001). The proportion of comorbidities and use of aspirin were higher in OA patients (p<0.001). The remaining GI risk factors were present in similar proportions in both groups. Use of selective COX-2 inhibitors or gastro-protective agents was higher in RA patients. CONCLUSION: Prolonged use of NSAIDs and concomitant glucocorticoid use were higher in RA patients, while comorbidities and concomitant aspirin use were predominant in OA patients. These results will provide insights for use in development of future guidelines for proper selection of NSAIDs and effective prevention of GI complications in arthritis patients.

BACKGROUND/OBJECTIVES: This is the first study to identify common genetic factors associated with the basal metabolic rate (BMR) and body mass index (BMI) in obese Korean women including overweight. This will be a basic study for future research of obese gene-BMR interaction. SUBJECTS/METHODS: The experimental design was 2 by 2 with variables of BMR and BMI. A genome-wide association study (GWAS) of single nucleotide polymorphisms (SNPs) was conducted in the overweight and obesity (BMI > 23 kg/m2) compared to the normality, and in women with low BMR (< 1426.3 kcal/day) compared to high BMR. A total of 140 SNPs reached formal genome-wide statistical significance in this study (P < 1 x 10(-4)). Surveys to estimate energy intake using 24-h recall method for three days and questionnaires for family history, a medical examination, and physical activities were conducted. RESULTS: We found that two NRG3 gene SNPs in the 10q23.1 chromosomal region were highly associated with BMR (rs10786764; P = 8.0 x 10(-7), rs1040675; 2.3 x 10(-6)) and BMI (rs10786764; P = 2.5 x 10(-5), rs10786764; 6.57 x 10(-5)). The other genes related to BMI (HSD52, TMA16, MARCH1, NRG1, NRXN3, and STK4) yielded P <10 x 10-4. Five new loci associated with BMR and BMI, including NRG3, OR8U8, BCL2L2-PABPN1, PABPN1, and SLC22A17 were identified in obese Korean women (P < 1 x 10(-4)). In the questionnaire investigation, significant differences were found in the number of starvation periods per week, family history of stomach cancer, coffee intake, and trial of weight control in each group. CONCLUSION: We discovered several common BMR- and BMI-related genes using GWAS. Although most of these newly established loci were not previously associated with obesity, they may provide new insights into body weight regulation. Our findings of five common genes associated with BMR and BMI in Koreans will serve as a reference for replication and validation of future studies on the metabolic rate.

The incidence rate of cervical cancer in Korea is still higher than in other developed countries, notwithstanding the national mass-screening program. Furthermore, a new method has been introduced in cervical cancer screening. Therefore, the committee for cervical cancer screening in Korea updated the recommendation statement established in 2002. The new version of the guideline was developed by the committee using evidence-based methods. The committee reviewed the evidence for the benefits and harms of the Papanicolaou test, liquid-based cytology, and human papillomavirus (HPV) testing, and reached conclusions after deliberation. The committee recommends screening for cervical cancer with cytology (Papanicolaou test or liquid-based cytology) every three years in women older than 20 years of age (recommendation A). The cervical cytology combined with HPV test is optionally recommended after taking into consideration individual risk or preference (recommendation C). The current evidence for primary HPV screening is insufficient to assess the benefits and harms of cervical cancer screening (recommendation I). Cervical cancer screening can be terminated at the age of 74 years if more than three consecutive negative cytology reports have been confirmed within 10 years (recommendation D).

BACKGROUND: In this report, we present the annual data of the intensive care unit (ICU) module of the Korean Nosocomial Infections Surveillance System (KONIS) from July 2008 through June 2009. METHODS: We performed a prospective surveillance of nosocomial urinary tract infections (UTI), bloodstream infections (BSI), and pneumonia (PNEU) at 101 ICUs in 57 hospitals using KONIS. Nosocomial infection (NI) rates were calculated as the numbers of infections per 1,000 patient-days or device-days. RESULTS: We identified 3,287 NIs during the study period: 1,787 UTIs (1,772 cases were urinary catheter-associated), 917 BSIs (797 were central line-associated), and 583 PNEUs (335 were ventilator-associated). The rate of urinary catheter-associated UTIs was 4.80 cases per 1,000 device-days (95% confidence interval, 4.58-5.03) and urinary catheter utilization ratio was 0.85 (0.849-0.851). Although the urinary catheter utilization ratios were lower in the hospitals with 400-699 beds than in the hospitals with 700-899 beds and more than 900 beds, the rates of urinary catheter-associated UTIs were higher in hospitals with 400-699 beds than in the larger ones. The rate of central line-associated BSIs was 3.27 (3.05-3.51) and the utilization ratio was 0.56 (0.559-0.561). The rate of ventilator-associated PNEUs was 1.86 (1.67-2.07) and the utilization ratio was 0.41 (0.409-0.411). The rate of ventilator-associated PNEUs was lower in July 2008-June 2009 than in July 2007-June 2008 and July 2006-December 2006. CONCLUSION: It appears that the KONIS influences the reduction in the rate of device-associated infections, especially ventilator-associated PNEU; therefore, ongoing targeted surveillance and infection control strategies are needed to control device-associated infections.

BACKGROUND: The purpose of this study was to examine the reproducibility of both the diagnosis of endometrial hyperplasia (EH) or adenocarcinoma, and the histologic grading (HG) of endometrioid adenocarcinoma (EC). METHODS: Ninety-three cases of EH or adenocarcinomas were reviewed independently by 21 pathologists of the Gynecologic Pathology Study Group. A consensus diagnosis was defined as agreement among more than two thirds of the 21 pathologists. RESULTS: There was no agreement on the diagnosis in 13 cases (14.0%). According to the consensus review, six of the 11 EH cases (54.5%) were diagnosed as EH, 48 of the 57 EC cases (84.2%) were EC, and 5 of the 6 serous carcinomas (SC) (83.3%) were SC. There was no consensus for the 6 atypical EH (AEH) cases. On the HG of EC, there was no agreement in 2 cases (3.5%). According to the consensus review, 30 of the 33 G1 cases (90.9%) were G1, 11 of the 18 G2 cases (61.1%) were G2, and 4 of the 4 G3 cases (100.0%) were G3. CONCLUSIONS: The consensus study showed high agreement for both EC and SC, but there was no consensus for AEH. The reproducibility for the HG of G2 was poor. We suggest that simplification of the classification of EH and a two-tiered grading system for EC will be necessary.

BACKGROUND: Cefoxitin, a cephamycin-type antibiotic, is known to be superior to oxacillin in predicting the presence of mecA gene because it serves as a very potent inducer of mecA regulatory system. We used a cefoxitin disk diffusion methods for detection of methicillin-resistant Staphylococcus aureus (MRSA), and compared it with the conventional methods. METHODS: For 50 MRSA and 50 methicillin susceptible S. aureus confirmed by mecA and femA gene PCR, oxacillin, cefoxitin, and moxalactam disk diffusion methods, oxacillin and cefoxitin E-tests, Vitek 2 and Microscan Walkaway antibiotics susceptibility tests, and PBP2a latex agglutination test were performed. The sensitivity and specificity of each method were evaluated. RESULTS: The sensitivities of oxacillin disk diffusion method and E-test were 96%. The sensitivities of cefoxitin and moxalactam disk diffusion method, cefoxitin E-test, Vitek 2, Microscan Walkaway, PBP2a latex agglutination test were 100%. The specificities were 100% for all the methods used. CONCLUSIONS: It may be considered that both the cefoxitin- and moxalactam disk diffusion methods are effective and excellent screening methods for the detection of MRSA in clinical laboratory routinely.

Four cases of primary transitional cell carcinoma (TCC) arising in the ovary (3 cases) and the parovarium (1 case) were collected for clinicopathologic analysis. The mean age was 46.2 years (range, 39-57 years). Two patients complained abdominal discomfort and vaginal discharge, respectively. Other 2 cases were incidentally found from routine check. Grossly, the tumors were solid and cystic (2 cases), solid (1 case) and surface papillary growth on capsule (1 case). Microscopically, the tumor showed almostly same to the histologic features of TCC of urinary bladder. Three cases were pure TCC, and one was mixed TCC and serous carcinoma. FIGO stage were 1 IIa, 2 IIc, and 1 IIIc. Treatment was surgery with adjuvant chemotherapy. Two patients are alive with no evidence of disease, and two have lung or brain metastasis.
