1.Fall Risk Factors and Characteristics of an Acute Hospital Setting across Clinical Departments.
Journal of Korean Academy of Fundamental Nursing 2014;21(3):264-274
PURPOSE: This study was done to determine inpatient fall rates in an acute hospital setting and to explore risk factors and characteristics across clinical departments. METHODS: The medical records and standardized fall reports of 416 patients admitted between January 1 and December 31, 2012 were reviewed. Descriptive statistics and statistical tests were used, including: t-test, chi2-test, ANOVA. RESULTS: The total fall rate per 1,000 inpatient days was 0.49. Fall rate, fall risk factors and characteristics such as age, type of fallers and mean MFS (Morse Fall Scale) differed significantly among clinical departments. CONCLUSIONS: The analysis results show that the fall rates, fall risk factors and characteristics of acute hospital inpatient falls varied significantly across clinical departments. The findings of this study suggest that hospitals should consider differences in fall related characteristics across clinical departments when implementation fall prevention strategies and interventions.

The Korean Journal of Laboratory Medicine 2005;25(4):241-246
BACKGROUND: The vanA gene cluster of vancomycin-resistant enterococci (VRE) is carried as a part of Tn1546-like elements. In this study we characterized the structure of Tn1546-like elements in Enterococcus. faecium isolated from patients in Korea. The isolates were also typed by pulsed-field gel electrophoresis (PFGE). METHODS: During 2000, 21 clinical isolates of vanA-containing E. faecium were collected from ten university hospitals in Korea. E. faecium BM4147 was used as a control. PFGE was performed on a CHEF-DR III apparatus. For structural analysis of Tn1546, the overlapping PCR amplification of internal regions of Tn1546 was performed. The purified PCR products were directly sequenced by using ABI Prism 3100 DNA SEQUENCER. RESULTS: All isolates were divided into 3 types according to the distribution of insertion sequences (IS elements) integrated Tn1546 elements. Type I and II were characterized by an IS1542 insertion in the orf2-vanR intergenic region and an IS1216V insertion in the vanX-vanY intergenic region. Type III represented two copies of IS1216V at the orf1 and in the vanX-vanY intergenic region as well as IS1542 in the orf2-vanR intergenic region. No isolates were identical to the prototype, which was identical to the predicted pattern for the published sequence of Tn1546. The PFGE results revealed that all strains except A13, C1, A2 and A9 were genetically unrelated. CONCLUSIONS: The distribution of IS in Tn1546-like elements of the Korean isolates is similar to that of the European VREs. Considering the results of PFGF and Tn1546 typing, the horizontal transfer of vanA resistance gene may be occurring among genetically diverse strains of E. faecium in Korea.

BACKGROUND: Vancomycin-resistant Enterococci (VRE) infections are caused by Enterococcus faecium in about 90% of the cases but can also be caused by Enterococcus faecalis. Thus, this study investigates factors that cause a low isolation rate of vancomycin-resistant E. faecalis (VREfs). To this end, the authors study the clinical traits, resistant gene structure, genomic classification, and molecular characteristics of the virulent factor. METHODS: From January 2001 through September 2011, 17 vanA-containing E. faecalis isolates were collected from hospitalized patients at Ajou University Hospital in Korea. Identification, antimicrobial susceptibility testing, and PCR of van and esp genes were performed. Pulsed-field gel electrophoresis (PFGE) was used for strain typing. PCR and sequencing of the internal regions of Tn1546 were performed for structural analysis of the van gene. RESULTS: Of 4,235 VRE infections, 3,918 (92.5%) were caused by E. faecium, and 95 (2.2%) were caused by E. faecalis. In 67% of VREfs infections, there was a preceding occurrence of E. faecium infection. All isolates were of genotype vanA. Our isolates were divided into three types according to the distribution of IS elements integrated into Tn1546 (types I to IIb). The PFGE results showed no clonal relatedness among isolates. CONCLUSION: Our study found that VREfs infections affect patients who have experienced vancomycin-resistant E. faecium. (VREfm) infection or undergo invasive procedures. The VREfs seems to involve the horizontal transfer of Tn1546 transposon from VREfm.

BACKGROUND: Nosocomial infections caused by vancomycin-resistant enterococci (VRE) are increasing problem in Korea. Until now, no nationwide study has been performed. The aim of the present study was to monitor the antimicrobial resistance of vancomycin-resistant Enterococcus faecium (VREF). METHODS: Two hundred and two E. faecium isolated in 10 teaching hospital were studied. To detect VRE, the brain heart infusion agar containing 6 /mL vancomycin was used as the screening agar. The MIC was determined using agar dilution test. The vancomycin resistance genes (vanA, vanB & vanD) and genes (aac(6 ') Ie-aph(2 ") Ia & ant(6 ') Ia encoding the aminoglycoside-modifying enzymes were detected by multiplex PCR using specific primers. RESULTS: Thirty-nine VREF were detected from 202 isolates. All had vancomycin MICs > or =256 /mL and harboured vanA gene. No isolates revealed positive results for the vanB or vanD gene. However, the MIC range for teicoplanin was 2 to > or =256 /mL. All isolates with gentamicin MIC > or = 500 /mL gave positive results for the aac(6 ') Ie aph(2 ") Ia genes and with streptomycin > or =2000 /mL gave positive results for the ant(6 ') Ia gene. CONCLUSIONS: All VREF harboured vanA gene. According to MIC tests, 7 isolates(18%) showed intermediate or susceptible to teicoplanin. Therefore we need a study concerning the clinical meaning. The VREF in Korea contain at least one of genes encoding the aminoglycoside-modifying enzymes. This means there are only limited numbers of antibiotics to choose.

Visible fungal colonization on peritoneal dialysis catheter is a rare complication and it was not reported yet in Korea. We here report a case of Alternaria spp. colonization on peritoneal dialysis catheter without peritonitis. A 58-year-old man on continuous ambulatory peritoneal dialysis for 2 years, noticed 3-4 mm sized two black-brown immobile fungal colonization plaque on peritoneal catheter lumen (15 cm distal from catheter exit site). The dialysate effluent was clear and culture for fungus and bacteria was negative. Peritoneal catheter was removed and culture from the plaque revealed saprophytic fungus, Alternaria species. The catheter removal alone was sufficient for the treatment. He is on hemodialysis thereafter.

Anemia is a common cause of referrals to gastroenterologists. Only a small number of anemia cases result from vascular abnormalities. Visceral artery aneurysms and pseudoaneurysms are rare forms of vascular disease that have significant potential for rupture, resulting in potentially life-threatening hemorrhaging. We present the case of a 70-year-old female patient with a pseudoaneurysm of the superior mesenteric artery complicated with rupture, who had no abdominal pain and only anemia.

Non-steroidal anti-inflammatory drugs (NSAIDs) are well known to be associated with serious upper gastrointestinal complications, such as peptic ulcer, bleeding, perforation, and obstruction. Recently, attention has been mainly focused on the small bowel injuries caused by NSAIDs, and new endoscopic techniques such as capsule endoscopy and double balloon endoscopy can help in detecting such injuries. This article reviewed the epidemiology, pathogenesis, clinical manifestations, diagnosis, and treatment of small bowel injuries caused by NSAIDs. Small bowel injures by NSAIDs might occur with a similar frequency and extent as those observed in the upper gastrointestinal tract. The pathogenesis of NSAID-induced enteropathy is complex and not clearly understood. The various lesions observed in the small bowel, including petechiae, reddened folds, loss of villi, erosions, and ulcers can be detected by capsule endoscopy. A drug that could prevent or treat NSAID-induced enteropathy has not yet been developed. Therefore, further investigations should be performed to elucidate the pathogenesis of such enteropathy and develop suitable preventive and treatment strategies.

Osteomas in the head and neck regions are benign bone neplasms usually found in the frontoethmoid area. Osteomas are usually produce symptoms secondary to pressure on adjacent structures. Although commonly discovered in the external auditory canal of the temporal bone, few cases have been reported in the mastoid or squamous portion of the temporal bone. When located in the mastoid and squamous parts of the temporal bone osteomas can cause cosmetic deformity such as external mass or an auricular protrusion. Other neoplasms of the mastoid region such as osteosarcoma and osteoblastic metastasis should be considered for the differential diagnosis. The authors experienced a case of osteoma that originated from mastoid of temporal bone. We report this rare case and its successful management with a review of the literatures.

In July 2010, we identified an outbreak of vancomycin-resistant enterococci (VRE) in our 26-bed neonatal intensive care unit. We performed an epidemiological investigation after clinical cultures of 2 neonates were positive for VRE. Identification, susceptibility testing, and molecular characterization were performed. Cultures of 3 surveillance stool samples of inpatients and 5 environmental samples were positive for VRE. All isolates were identified as Enterococcus faecium containing the vanA gene. Two distinct clones were identified by performing pulsed-field gel electrophoresis. The 2 clones exhibited different pulsotypes, but they represented identical Tn1546 types. Two sequence types, ST18 and ST192, were identified among all of the isolates with multilocus sequence typing. Our investigation determined that the outbreak in the neonatal intensive care unit was caused by 2 genetically different clones. The outbreak may have occurred through clonal spread and horizontal transfer of the van gene.

BACKGROUND/AIMS: Guanine nucleotide binding protein (G-protein) beta polypeptide 3 (GNB3) C825T polymorphism alters intracellular signal transduction, which may lead to motor or sensory abnormalities of the gastrointestinal tract. The aim of the present study was to evaluate the association of the GNB3 C825T polymorphism with susceptibility to overlap syndrome of functional dyspepsia (FD) and irritable bowel syndrome (IBS) in a Korean population. METHODS: One hundred sixty-seven patients with FD alone, 60 patients with IBS alone, 85 patients with the overlap of FD and IBS, and 434 asymptomatic healthy subjects participated in the study. Genotyping for GNB3 C825T polymorphism was performed using their blood samples. RESULTS: No association of GNB3 genotypes in patients with FD alone, IBS alone or overlap phenotype, when compared to genotypes in controls, was detected. The frequency of CT and TT genotypes relative to the CC genotype for the phenotypes of FD alone, IBS alone and the coexistence of FD and IBS did not significantly differ. Comparison of the TT genotype with the CC/CT genotype showed no significant association for each phenotype group. CONCLUSIONS: There is no apparent association of the GNB3 C825T polymorphism with the susceptibility to FD, IBS or the overlap of FD and IBS. Larger-scale studies and further investigation on other candidate genes are required.
