PURPOSE: Recently, vancomycin-resistant enterococci (VRE) have become one of the major nosocomial pathogens in Korea. However, there have been few studies on the epidemiology of VRE colonization among neonates. In this study, we investigated the prevalence of VRE colonization, risk factors for VRE, and how to control the spread of VRE infection in the Neonatal Intensive Care Unit (NICU) of Pusan National University Hospital (PNUH). METHODS: We retrospectively reviewed medical records of 192 neonates who were admitted to the NICU of PNUH from March 2006 to March 2007. Surveillance cultures from rectal swabs for detecting VRE were obtained weekly during the study period. We analyzed the prevalence of VRE and various risk factors. RESULTS: The rate of VRE colonization among NICU patients was 25% (48/192). Thirty five of these VRE colonized patients were transferred to the NICU from other local hospitals. Compared with the non-VRE group, the risk factors associated with VRE colonization were lower birth weight, congenital heart disease, applied mechanical ventilation, use of a central venous catheter, chest tubing, a history of surgery, and use of antibiotics. CONCLUSION: VRE colonization among patients admitted to the NICU is rapidly increasing. Monitoring and managing premature neonates from the beginning of the birth process, avoiding many invasive procedures, avoiding antibiotics such as vancomycin and third generation cephalosporin are important for preventing the emergence and spread of VRE colonization in the NICU.

Introduction: In recent years, the internet has become an increasingly popular tool for people to obtain information due to the overwhelming availability of material. As internet access becomes more readily available, the newer generation of patients, medical students and doctors are starting to prefer the internet as a source of reference to acquire medical knowledge. The main objectives of this study were to determine the accuracy of using Google search in establishing a clinical diagnosis based on information provided from the New England Journal of Medicine (NEJM) and to determine the concordance rate of Google diagnosis with the actual diagnosis from NEJM. Method: The research design was a cross sectional study of 200 NEJM cases. The research team comprised of four 3rd year medical students and one senior supervisor. Google search engine was used to obtain a diagnosis. The time allocated for a Google search for each case was 20 minutes regardless of the number of websites used. The top two diagnoses were then compared to the actual diagnoses of the NEJM case and the accuracy of Google was then assessed. Results: The study achieved a congruence of 71.5%. This is considered acceptable and satisfactory as the cases presented in NEJM covered a wide variety of problems and encompassed rare diseases. Conclusion: From the final results obtained, it can be concluded that with the aid of Google, medical students in their 3rd year of their Bachelor of Medicine and Bachelor of Surgery programme are able to obtain a reasonable clinical diagnosis.

PURPOSE: To report the causes and patterns of death among infants admitted to our neonatal intensive care unit (NICU) over a 13-year period. In addition, we analyzed trends regarding the type of end-of-life care provided. METHODS: All of the neonates who died at the Soonchunhyang University Bucheon Hospital between January 1, 2002, and December 31, 2014, were identified. The causes and circumstances of death were extracted from individual medical records. Trends in mortality were compared between two time periods: 2002 to 2007 and 2008 to 2014. RESULTS: Of the 5,223 admissions to our NICU, 97 neonates died. The overall mortality rate was 1.9%. The most common cause of death was sepsis (15%). At a lower gestational age, infants died of extreme prematurity and complications of prematurity. Among term infants, the principal cause of death shifted to hypoxic ischemic encephalopathy and asphyxia. A total of 63 infants (64.9%) received maximal intensive care, and 34 infants (35%) had redirection of intensive care. During this period, the proportion of death after redirection of care increased from 30.6% to 39.6%. Infants decided to forgo life-sustaining care before death had significantly lower gestational ages and lower birth weights (30.5 vs. 27.1 weeks, P=0.005; 1,528 vs. 1,063 g, P=0.025). CONCLUSION: Infection remained an important cause of death for neonate, particularly for preterm infants. The proportion of infants who had redirectoin of care before death was increased, suggesting that quality-of-life should be considered an important factor in the decision-making process for the infant, parents, and medical staff.

Kimchi is a traditional Korean food prepared by fermenting vegetables, such as Chinese cabbage and radishes, which are seasoned with various ingredients, including red pepper powder, garlic, ginger, green onion, fermented seafood (Jeotgal), and salt. The various unique microorganisms and bioactive components in kimchi show antioxidant activity and have been associated with an enhanced immune response, as well as anti-cancer and anti-diabetic effects. Red pepper inhibits decay due to microorganisms and prevents food from spoiling. The vast amount of biological information generated by academic and industrial research groups is reflected in a rapidly growing body of scientific literature and expanding data resources. However, the genome, biological pathway, and related disease data are insufficient to explain the health benefits of kimchi because of the varied and heterogeneous data types. Therefore, we have constructed an appropriate semantic data model based on an integrated food knowledge database and analyzed the functional and biological processes associated with kimchi in silico. This complex semantic network of several entities and connections was generalized to answer complex questions, and we demonstrated how specific disease pathways are related to kimchi consumption.

Purpose: The objective of this study was to determine the optimal timing of inguinal herniorrhaphy in preterm infants to reduce the risks of preoperative incarceration and postoperative complications. Methods: Preterm infants with gestational age (GA) of <37 weeks who had ingui­nal herniorrhaphy before the age of 6 months were enrolled. Early repair was defined as undergoing herniorrhaphy before discharge from the neonatal intensive care unit (NICU), and late repair was defined as undergoing herniorrhaphy as an outpatient after discharge from the NICU. Results: The incidence rates of preoperative incarceration and recurrence were not significantly different between the two groups. Postoperative apnea and mechanical ventilation were more frequent in the early-repair group than in the late-repair group.Postoperative apnea was more frequent in the early-repair group after adjustments for GA and birth weight. However, no significant difference in postoperative mechanical ventilation was found between the two groups after adjustments for GA and birth weight. The incidence of postoperative apnea was associated with small weight at repair, early repair, general anesthesia, younger GA, small weight at birth, and bron chopul­monary dysplasia. Contralateral metachronous hernia was most frequent in infants with small weight at repair, early repair, very low birth weight (VLBW), male sex, and right-sided hernia. Conclusion Late repair was safe and did not increase the risk of incarceration or recurrence, but decreased the risks of postoperative apnea and metachronous hernia.Regional anesthesia could reduce the risk of postoperative apnea. Male infants born with VLBWs and right-sided hernia should be followed up carefully for metachronous hernia.

PURPOSE: Meconium-related ileus is common in preterm infants. Without proper management, it can cause necrotizing enterocolitis and perforation requiring emergent operation. This study was conducted to describe the efficacy and safety of ultrasound-guided Gastrografin enema at bedside for preterm infants with meconium-related ileus. METHODS: Between March 2013 and December 2014, this study enrolled preterm infants with birth weight < 1,500 g, who were diagnosed with meconium-related ileus requiring ultrasound-guided Gastrografin enema refractory to glycerin or warm saline enemas. Gastrografin was infused until it passed the ileocecal valve with ultrasound guidance at bedside. RESULTS: A total of 13 preterm infants were enrolled. Gestational age and birth weight were 28.6 weeks (range, 23.9–34.3 weeks) and 893 g (range, 610–1,440 g), respectively. Gastrografin enema was performed around postnatal day 8 (range, day 3–11). The success rate was 84.6% (11 of 13 cases). Three of these 11 infants received a second procedure, which was successful. Among 2 unsuccessful cases, one failed to pass meconium while the other required surgery due to perforation. The time required to pass meconium was 2.8±1.5 hours (range, 1–6 hours). The time until radiographic improvement was 2.8±3.4 days (range, 1–14 days) after the procedure. CONCLUSION: Ultrasound-guided Gastrografin enema at bedside as a first-line treatment to relieve meconium-related ileus was effective and safe for very low birth weight infants. We could avoid unnecessary emergent operation in preterm infants who have high postoperative morbidity and mortality. This could also avoid transporting small preterm infants to fluoroscopy suite.

PURPOSE: This study was performed to evaluate the current status of food allergy (FA) and to analyze the relationship between allergy to individual foods and other allergic diseases in elementary school children. METHODS: We performed a questionnaire survey for FA, asthma, allergic rhinitis, and atopic dermatitis using International Study of Asthma and Allergies in Childhood questionnaires. A total of 1,929 students in 3 elementary schools were enrolled. RESULTS: A total of 324 students (16.8%) had ever suffered from FA symptoms more than once. Only 64 out of 324 students (19.8%) were diagnosed with FA by doctors. The presence of soy allergy was associated with the increased risk of bronchial asthma (adjusted odds ratio [aOR], 5.90; 95% confidence interval [CI], 1.87 to 18.59). The presence of egg (aOR, 1.91; 95% CI, 1.04 to 3.52) and wheat allergy (aOR, 5.45; 95% CI, 1.94 to 15.36) were associated with the increased prevalence of allergic rhinitis. The allergic symptoms to fruits/tomato was associated with the increased risk of allergic rhinoconjunctivitis symptoms (aOR, 2.98; 95% CI, 1.18 to 7.47). The allergic symptoms to egg (aOR, 2.29; 95% CI, 1.22 to 4.29), wheat (aOR, 4.91; 95% CI, 1.86 to 12.95), and shrimp/crab (aOR, 2.48; 95% CI, 1.37 to 4.49) were associated with the presence of atopic dermatitis. CONCLUSION: The prevalence of FA of elementary school students in Bucheon-city was 16.8%. A significant positive association between the suspected foods and the other allergic diseases was found. Soy allergy was significantly correlated to having bronchial asthma and fruits/tomato allergy correlated with allergic rhinoconjunctivitis.

Local allergic rhinitis (LAR) is a localized nasal allergic response in the absence of systemic atopy. The aim of this study was to evaluate the prevalence and clinical characteristics of LAR in Korean rhinitis patients compared to allergic rhinitis (AR) and non-allergic rhinitis (NAR). A total of 304 rhinitis patients were enrolled from November 2014 to March 2016. A skin prick test, serum total and specific immunoglobulin E, and a nasal provocation test (NPT) with house dust mite (HDM) were performed on all patients. Subjects also documented changes in rhinitis symptoms before and after NPT. Seventy-four patients with nasal hyper-reactivity and 80 patients with subclinical allergy were excluded. AR was diagnosed in 69 (46.0%) patients, NAR in 75 (50.0%) patients, and LAR to HDM in 6 (4.0%) patients. The average medication score and disease duration of each group were 14.5 points and 77.6 months in AR, 12.1 point and 51.1 months in NAR, and 17.7 point and 106.0 months in LAR, respectively. There were no significant differences in the baseline nasal symptom score of the three groups. However, after NPT with HDM, the score of rhinitis, itching, and obstructive were 4.83±1.47 vs. 1.95±2.53, 3.00±2.10 vs. 1.45±2.06, and 5.50±1.38 vs. 2.57±2.84 in LAR and NAR, respectively (p<0.05). LAR patients had longer duration of disease and tended to be older and have higher medication score than other rhinitis patients.

In experimental sutureless muscle surgery with tissue adhesives, current materials have inadequate adhesive strength in the early postoperative period.We performed a modified muscle surgery using a stitch combined with Tisseel (Immuno AG, Vienna, Austria)in order to evaluate the adhesive strengh as a replacement for conventional suture techniques in muscle surgery. Thirty eyes of 15 rabbits were used.We recessed superior and inferior rectus muscles by three different methods, Tisseel only, a stitch with Tisseel, and a stitch only, in each group of 5 rabbits.Conjunctival incisions were closed with the remaining Tisseel in 7 rabbits, and with vicryl in 8 rabbits. Tensile strength of the scleral reattachment site was measured and conjunctival closure was examined by slit-lamp biomicroscopy, at intervals of 1 hour, 12 hours, 1 day, 3 days and 5 days. The strengths of a stitch with Tisseel at each interval were 83.25 +/-1 4 .0 6 gm, 137.50 +/-22.88 gm, 169.75 +/-23.95 gm, 151.50 +/-41.99 gm, and 265.50 +/- 25.01 gm, respectively.The strengths of Tisseel alone were 61.50 +/-2 0 .2 1 gm, 101.50 +/-11.00 gm, 113.25 +/-28.69 gm, 120.50 +/-18.36 gm, and 222.75 +/- 57.67 gm.They were 52.25 +/-24.85 gm, 89.50 +/-16.05 gm, 130.75 +/-21.98 gm, 1 5 3 .7 5 +/-30.35 gm, and 261.50 +/-60.47 gm at each interval in rabbits with a stitch alone. These results showed that the tensile strengths of a stitch with Tisseel were stronger than those of the other two methods up to 1 day after surgery.Even at postoperative 12 hours, the strength was more than 130 gm which was strong enough for scleral attachment.All of the conjunctival closures with Tisseel were well maintained without any complication up to 5 days, the same as vicryl sutures. In conclusion, this study revealed that muscle attachment to the sclera by a stitch with Tisseel was simpler and safer than classical sutures with reduced risk of sclera perforation.Its strong tensile strength at early postoperative days suggests that the method might be considered as an alternative method to classical reattachment using suture material and also that conjunctiva could be closed with Tisseel remnant.
