BACKGROUND: It is well known that Methicillin-resistant Staphylococcus aureus (MRSA) is hardly controllable organism among pathogens of nosocomial infection. The MRSA infection control measures have been initiated at a brand new tertiary care teaching hospital which was opened in June, 1994. However, the control measures did bring out little effect. In 1997, reenforcement of all control measures were practiced in intensive care units. The measures brought out a significant improvement in reducing the incidence of MRSA infection, subsequently the same control measures were implemented through-out the entire inpatient area. METHODS: The following control measures have been reenforced since March 1997: first, application of thorough surveillance of confirmed MRSA infected patients: second, providing cohort care: third, enforcing handwashing practices after patient contact; fourth, establishing infected patients isolation zone: fifth, tagging infected patient's bed and medical record, providing disinfectant spray for washing hands, identifying and treating carriers among patient contact staffs, separate disposal of contaminated wastes, and finally repeating education of nursing staff and family members of the patients. Each month the number of incidence in MRSA nosocomial infection were followed and the leu supervisors were notified the outcome. RESULTS: The incidence of MRSA infection started to decline soon after the initiation of the control measures, from 132% in March 1997 to 5.8% in July 1997. In 1998, the infection rate maintained close to 2-3%. There had been 467 MRSA infected cases (5.7%) out of 8,253 discharges during the study period; among them 319 cases were infected once; 40 cases twice; 15 cases three times: four cases four times and 1 case seven times. The order of preference of organs infected are lungs (56.3%), wounds(11.8%), blood (7.9%), and urinary tract (1.9%). The highest incidence of this infection was found in Medicine (34.8%) and Neurosurgery (22.8%) CONCLUSION: The implementation and reenforcement of infection control measures are key to successful control of nosocomial infection, in particular, hand washing of patient contact staffs and eradication of carriers could be the most effective measures.

OBJECTIVE: The objective of this study was to compare perinatal outcomes of pregnancy-induced hypertensive and normotensive women experiencing abruptio placentae, Our hypothesis is that pregnancy-induced hypertensive women have a less favorable perinatal outcome than do normotensive women. METHODS: Women with the diagnosis of abruptio placentae delivered between August 1, 1989 and December 1, 1996, composed the study group (n=92) in this case-control study. The women with abruptio placentae were divided according to their hypertensive (n=37) or normotensive (n=55) status. Maternal and neonatal medical records were reviewed and abstracted for demographic variables, antepartum complications, delivery route, abruptio placentae grade, neonatal gender, birth weight, Apgar score and perinatal mortality. We compared these perinatal outcome variables between the pregnancy-induced hypertensive and normotensive pregnant women. RESULTS: The incidence of abruptio placentae was 0.35%. The two groups of woman wne similar with regard to age and parity. Abruptio placentae grades 2 occurred more often in hypertensive women (P=0.0053). Pregnancy-inducedhypertensive women were similar to normotensive women with regard to antenatal complications. The mean gestational age of delivery, delivery route, neonatal weight and sex were similar between two groups of women. Neonates from pregnancy-induced hypertensive women were no more likely to have low 1 and 5-minute Apgar score or to die than those from normotensive women. Statistical analysis was performed with two-tailed independent t-test and Kruskal-Wallis analysis. CONCLUSION: Although pregnancy-induced hypertensive women experiencing abruptio placentae are more likely to have grade 2 abruptio placentae with fetal distress, the overall perinatal outcome was not significantly different from that of normotensive women experiencing abruptio placentae.

Cancer of the stomach is responsible for approximately 650,000 deaths globally each year and is probably second only to lung cancer worldwide as an overall cause of cancer-related mortality. Similar to the situation with most adenocarcinomas of the gastointestinal tract, carcinomas of the stomach can spread by local extension to adjacent normal structures and can develop lymphatic, peritoneal, and distant metastases. The tumor cells, can also permeate diffusely into the lymphatic plexus of the bowel, more often at the level of the upper duodenum hut sometimes down into the distal ileum and the large bowel. We report a case of lymphatic metastasis of gastric adenocarcinoma to the ampulla of Vater with review of the literature.

OBJECTIVES: This study sought to investigate the relationship between age, sex and alterations in levels of % carbohydrate-deficient transferrin (%CDT) and gamma-glutamyl transferase (GGT) in patients admitted with alcohol dependence. METHODS: The study retrospectively enrolled 187 patients who were diagnosed with alcohol dependence according to the Diagnostic and Statistical Manual of Mental Disorders-Fourth edition (DSM-IV) and were admitted into a closed ward in Hallym University Hangang Sacred Heart Hospital from 2009 to 2012 and Hallym University Kangnam Sacred Heart Hospital from 2012 to 2017. Demographic factors (age, sex) and biochemical markers [%CDT, GGT, mean corpuscular volume (MCV), aspartate transferase (AST), alanine transferase (ALT)] were collected by reviewing medical records. Alterations in the levels of %CDT and GGT in different groups for each demographic factor were compared after correcting for confounding variables (age, initial %CDT, GGT, MCV, AST, ALT). RESULTS: Decreased %CDT and GGT were observed during the period of abstinence after admission. The normalization period for %CDT increased with age, while the normalization period for GGT was longer in female patients. CONCLUSIONS: These results suggest that alcohol-dependent patients that vary in age have different alterations in %CDT, while different sexes have different alterations in GGT. Age and sex can be potential indicators of treatment response after abstinence in patients with alcohol dependence. Further studies are needed to evaluate the relationship between these factors with regards to physiological and hematological changes in alcohol dependence.

Background/Aims:
A new medical fiber-guided diode laser system (FDLS) is expected to offer high-precision cutting with simultaneous hemostasis. Thus, this study aimed to evaluate the feasibility of using the 1,940-nm FDLS to perform endoscopic submucosal dissection (ESD) in the gastrointestinal tract of an animal model.
Methods:
In this prospective animal pilot study, gastric and colorectal ESD using the FDLS was performed in ex vivo and in vivo porcine models. The completeness of en bloc resection, the procedure time, intraprocedural bleeding, histological injuries to the muscularis propria (MP) layer, and perforation were assessed.
Results:
The en bloc resection and perforation rates in the ex vivo study were 100% (10/10) and 10% (1/10), respectively; those in the in vivo study were 100% (4/4) and 0% for gastric ESD and 100% (4/4) and 25% (1/4) for rectal ESD, respectively. Deep MP layer injuries tended to occur more frequently in the rectal than in the gastric ESD cases, and no intraprocedural bleeding occurred in either group.
Conclusions
The 1,940-nm FDLS was capable of yielding high en bloc resection rates without intraprocedural bleeding during gastric and colorectal ESD in animal models.

BACKGROUND: Enterococcal infections have become extremely difficult to manage because of an increase in antibiotic resistance among enterococci. In Europe, the use of avoparcin in animals was reported to be the cause of vancomycin-resistant enterococci (VRE) transmission to humans. In this study, we performed antimicrobial susceptibility testing and pulsed-field gel electrophoresis (PFGE) to characterize the genetic relatedness of VRE of human and chicken. METHODS: Ninety strains of VRE were isolated from clinical specimens in three University hospitals located in Seoul and Kyungi province in 2001-2002. Thirty isolates of VRE were collected from four chicken farms located in areas remotely distanced from each other. The isolates were identified to the species level by conventional biochemical tests and commercial kits. Antimicrobial susceptibilities were tested by the NCCLS disk diffusion and agar dilution methods. For a molecular epidemiologic analysis, PFGE was performed. RESULTS: Among the 90 clinical isolates were 73 vancomycin-resistant Enterococcus faecium (VREFM) and 17 vancomycin-resistant E. faecalis (VREFA). The resistant rates of VREFA to ampicillin, levofloxacin and tetracycline were 0%, 100%, and 100%, respectively, and for VREFM, 100%, 96%, and 26%, respectively. However, the resistant rates of VREFM isolated from chicken were 19% to ampicillin, 0% to levofloxacin, and 100% to tetracycline. The PFGE patterns of genomic DNA of the clinical isolates were very diverse, suggesting a polyclonal spread of VRE, although some isolates had an identical PFGE pattern, indicating a mini-outbreak due to a clonal spread. The PFGE patterns of genomic DNA of the chicken isolates were very different from those of the human isolates. CONCLUSIONS: VRE isolates from human and chicken showed very different antimicrobial susceptibilities and PFGE patterns. These results suggest that VRE isolated from human and chicken are not closely related genetically.
