BACKGROUND: This study was performed to evaluate the results of intervention activities on the management of steam sterilizers and sterile items in out-patient clinics and clinical laboratories. METHODS: A checklist was developed and used to monitor and evaluate the adequacy of sterilizers and sterilized items at out-patient clinics and clinical laboratories in a tertiary-care hospital. The checklist consisted of 7 items: condition of the material used for packaging sterile items, maintenance of shelf-life records, sterilizer cleanliness, maintenance of expiry date details of sterilized items, sterilization conditions, use of chemical indicators, and the results of biological indicators. Monitoring and additional intervention activities were carried out once every week for 53 weeks from August 2007 to July 2008. The study period was divided into 2 terms, early and late intervention; the duration of each term was 6 months, and we compared the ratio of adequacy of management of sterilizer and sterilized items between the 2 terms. RESULTS: There were a total of 795 observations from 15 departments in 1 year. Sterility of the materials used for packaging increased from 87.4% in the first 6-month term to 97.9% in the second 6-month term. Records for shelf-life increased from 89.6% to 98.5% in the same period, while the figures for maintaining expiry date details of sterilized items and for steam sterilizer cleanliness increased from 92.6% to 99.2%, and from 91.9% to 98.5 (P<0.05), respectively. CONCLUSION: Our intensive checklist-based intervention was effective in improving the management of steam sterilizers and sterile items in out-patient clinics and clinical laboratories.

PURPOSE: The purpose of this study was to investigate the effects of case-based learning (CBL) on learning motivation and learning satisfaction of nursing students in a human physiology course. METHODS: The development and application of CBL scenarios was conducted from February to June, 2013. Nursing students (n=142) who registered for a human physiology course were assigned into either a control or CLB group. The control group received traditional lectures for 14 weeks. The CBL group received the same 14-week lectures and an additional 5 CBL sessions. The learning motivation and satisfaction were measured by questionnaires at the beginning and the end of the semester. Seven students in the CBL group were randomly selected for a focus-group interview. Quantitative data were analyzed by chi2-test and t-test, and qualitative data were analyzed by content analysis. RESULTS: The learning motivation and learning satisfaction were not significantly different between the two groups. However, 59% of the CBL group answered with a positive impression on the CBL approach as it helped them to feel a sense of achievement, excitement, to form their identity as nursing students, and so on. CONCLUSION: These findings suggest that the CBL could be a challenging but useful learning method in a physiology course for nursing students. Further studies with guidance, such as instructors' questions and feedback design are needed to utilize CBL more effectively.

Colonoscopy is commonly used to screen for and diagnose colorectal disease, and adequate bowel preparation is crucial to its quality. As bowel preparation regimens vary, it is important that clinicians understand each and select the proper one for each patient.Accordingly, here we investigated recent studies and describe how to choose the optimal bowel preparation regimen. We detail composition, dosages, efficacy, contraindications, and precautions of commonly used regimens including 4 L polyethylene glycol (PEG), 2 L PEG+ascorbic acid, 1 L PEG+ascorbic acid, trisulfate (oral sulfate solution/ tablets), and sodium picosulfate/magnesium citrate. Here we describe that the most recently introduced 1 L PEG and oral sulfate tablets, which were developed to improve convenience and compliance, differ in composition and efficacy between South Korea and foreign countries. This review presents new evidence of and differences among products to increase clinician understanding.

To describe three cases of neovascular glaucoma (NVG) where iris or angle neovascularization regressed remarkably after subconjunctival bevacizumab injections used as the initial treatment before pan retinal photocoagulation (PRP) and/or filtering surgery. Three consecutive NVG patients whose intraocular pressure (IOP) was not controlled with maximal medication were offered an off-label subconjunctival injection of bevacizumab (2.5-3.75 mg/0.1-0.15 mL, Avastin). Bevacizumab was injected into the subconjunctival space close to the corneal limbus in two or three quadrants using a 26-gauge needle. Serial anterior segment photographs were taken before and after the injection. Following subconjunctival injection of bevacizumab, iris or angle neovascularization regressed rapidly within several days. Such regression was accompanied by lowering of IOP in all three cases. The patients underwent subsequent PRP and/or filtering surgery, and the IOP was further stabilized. Our cases demonstrate that subconjunctival bevacizumab injection can be potentially useful as an initial treatment in NVG patients before laser or surgical treatment.

Bortezomib (Velcade(R)) is proteasome inhibitor that is used as a first-line therapy for multiple myeloma. It can cause gastrointestinal, hematologic, and neuromuscular side effects, and a cutaneous reaction is one of its common adverse reactions. To date, several bortezomib-induced cutaneous adverse reactions have been reported, including folliculitis-like rash, pruriginous rash, purpuric rash, mouth swelling, stomatitis-mucositis, edema in the lower limbs, telogen effluvium, and vasculitis. In the Korean literature, only one case of vasculitis has been reported earlier. Two patients have presented with multiple plaques on the trunk at our clinic. The lesions developed several days after bortezomib chemotherapy, and disappeared spontaneously in about 1 week. Herein, we report bortezomib-induced drug eruption presenting as multiple plaques on the trunk with a review of the relevant literature.

Background: Fecal microbiota transplantation against gut colonization using a multidrugresistant organism is a technique used to treat infections through normalizing the gut microbiota via fecal microbiota transplantation in patients with confirmed colonization by carbapenem-resistant Enterobacteriaceae (CRE) or vancomycin-resistant enterococci (VRE) based on a fecal culture test within the past one week. In this study, we aimed to determinethe safety and effectiveness of this technique. Methods: The safety and effectiveness were assessed via a systematic review. A literature search was conducted using five Korean databases, such as KoreaMed, and international databases, including Ovid-MEDLINE, Ovid-EMBASE, and Cochrane Library. Results: Main results are described here. From the studies retrieved using the aforementioned search strategy, the remaining 581 studies were screened using the inclusion and exclusion criteria, resulting in the selection of nine studies for further consideration. In terms of safety, many studies reported deaths and adverse reactions associated with different causes. Fewer studies reported the rate of colonization; however, the effect of colony rate was inconsistent when compared to no treatment group. Additionally, none of the studies assessed the recurrence rate, a decrease in the prevalence of diseases related to infection by multidrugresistant bacteria, and the quality of life. Conclusion Fecal bacterial colonization for the decolonization of intestinal multidrugresistant bacteria was evaluated using a technique that requires further research as there is insufficient literature evidence to validate its safety and efficacy in treating infections through normalizing the intestinal flora of patients with confirmed colonization by CRE or VRE.

Purpose: This study was an quasi-experimental study to compare the effect of applying polyethylene wrap and aircap in maintaining body temperature of preterm infants. Methods: The participants were 51 preterm infants.Aircap was applied to the experimental group (n=23) and polyethylene wrap was applied to the control group (n=28) when the preterm infants admitted to neonatal intensive care unit. The data was collected at W hospital in J-province from June 2016 to May 2017. A total of 9 body temperature measurements were taken at 3 hours interval from 5 min to 24 hours after admission. Repeated measure ANOVA, independent t-test and x 2 test were conducted used with SPSS/WIN 24.0 Results: There were no significant difference in the homogeneity tests for general characteristics and dependent variables prior to the experiments (t=0.57, p=.566). There was a significant difference on body temperature of preterm infants over time (F=3.24, p=.020). There was no significant difference on body temperature between polyethylene wrap and aircap application groups (F=1.29, p=.261). The interaction between the group and the time was insignificant (F=1.51, p=.214). Conclusion The findings demonstrated that both methods of applying polyethylene wrap and aircap on the body in preterm infants had effect in maintaining body temperature.

The aim of this study is to investigate the status of the websites of plastic surgery clinics in Seoul, and to elucidate the factors that affect the page views. Directors of the clinics were asked by telephone as to whether their clinics have an website, and the rank of their sites were measured using the Navvy (ve r 2.75) program. The gene ral characteristics of each clinic and directors were surveyed using the list of members for the Korean association of clinical plastic surgeons. The characteristics of the websites were also surveyed and categorized into their accessibility, introduction, contents, interactions, and etc. The relationship between each variable, the possession of a homepage and the rank were analyzed by univariate analysis and the independent effects of these variables were examined by multiple logistic regression analysis. The results are as follows: 196 out of 252 clinics(77.8%) had a website and 77 of these sites were ranked below the 150,000th place. In multiple logistic regression analysis, younger directors had a higher likelihood of possessing a website, and the location of the clinic also significantly affected whether or not there was a website. The websites of the clinics located in Kangnam/Seocho-gu and run by more than 2 plastic surgeons had a higher tendency to rank be low the 150,000th place. However, the char acteristic s of the website did not aff ect the r ank distribution. Considering the above results, the characteristics of the clinics and surgeons may contribute greatly for the clinics to have a website and to have a high rank. In addition, the characteristics of the site may not be a major influencing fac tor.

PURPOSE: To evaluate the biological effects and cytotoxicity of gel-type artificial tears on human corneal keratocytes and conjunctival cells in vitro. METHODS: Human corneal keratocytes and conjunctival epithelial cells were exposed to Soothe(R) and Systane(R) at variable concentrations. Evaluations were conducted through an MTT-based calorimetric assay to measure the metabolic activity and through a lactate dehydrogenase (LDH) assay to assess cellular damage. Apoptotic response was examined using fluorescent microscopy and flow cytometric analysis, and cellular morphologic results were evaluated with a transmission electron microscope. RESULTS: The inhibitory effects of corneal keratocyte and conjunctival cell proliferations increased at higher concentrations and longer exposure times to Soothe(R) and Systane(R). The LDH titers increased after Soothe(R) exposure, but showed no significant difference after Systane(R) exposure. Soothe(R) and Systane(R) treatments both produced fluorescence, representing apoptotic cells. In flow cytometry, the maximal apoptotic response was observed for both types of artificial tears, although Systane(R) showed less edema, as well as reduced cytoplasmic and nuclear cell degeneration compared to those of Soothe(R). CONCLUSIONS: The apoptotic responses of Soothe(R) and Systane(R) are associated with inhibitory effects of human corneal keratocyte and conjunctival epithelial cell proliferations. To inhibit the cellular proliferation of human corneal keratocytes and conjunctival epithelial cells, Systane(R) may be less severe than Soothe(R) at higher concentrations and longer exposure times.
