PURPOSE: Long-term results following bariatric surgery compared to conventional treatments has never been reported in morbidly obese Korean patients. This study aimed to evaluate the long-term efficacy of bariatric surgery in morbidly obese Korean patients compared to conventional medical treatments. METHODS: In this multicenter retrospective cohort study, we reviewed 137 obese subjects between January 2008 and February 2011 with a body mass index (BMI) > 30 kg/m2 who had more than 5 years of follow-up clinical data after bariatric surgery (surgery group, n = 49) or conventional treatment (conventional treatment group, n = 88). Anthropometric data and the status of comorbidities were compared between the 2 groups. RESULTS: The median follow-up period was 72.1 months (range 19.3–109.7 months). At the last follow-up, the surgery group showed a greater amount of total weight loss than the conventional treatment group (24.9% vs. 2.8%, P < 0.001). The prevalence of diabetes and hypertension significantly decreased in the surgery group, while the conventional treatment group showed a marked increase in these comorbidities. In the surgery group, Roux-en-Y gastric bypass and sleeve gastrectomy achieved comparable long-term weight loss (26.5% vs. 22.4%, respectively; P = 0.087). CONCLUSION: In the long-term, bariatric surgery achieved and maintained significantly greater weight reduction, as well as a decrease in obesity-related comorbidities, than did conventional medical therapy in morbidly obese Korean patients.

PURPOSE: Bariatric surgery is relatively new in Korea, and studies comparing different bariatric procedures in Koreans are lacking. This study aimed to compare the clinical outcomes of laparoscopic adjustable gastric banding (LAGB), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG) for treating morbidly obese Korean adults. MATERIALS AND METHODS: In this multicenter retrospective cohort study, we reviewed the medical records of 261 obese patients who underwent different bariatric procedures. Clinical outcomes were measured in terms of weight loss and resolution of comorbidities, such as diabetes, hypertension, and dyslipidemia. Safety profiles for the procedures were also evaluated. RESULTS: In terms of weight loss, the three procedures showed similar results at 18 months (weight loss in 52.1% for SG, 61.0% for LAGB, and 69.2% for RYGB). Remission of diabetes, hypertension, and dyslipidemia was more frequent in patients who underwent RYGB (65.9%, 63.6%, and 100% of patients, respectively). Safety profiles were similar among groups. Early complications occurred in 26 patients (9.9%) and late complications in 32 (12.3%). In the LAGB group, five bands (6.9%) were removed. Among all patients, one death (1/261=0.38%) occurred in the RYGB group due to aspiration pneumonia. CONCLUSION: The three bariatric procedures were comparable in regards to weight-loss outcomes; nevertheless, RYGB showed a higher rate of comorbidity resolution. Bariatric surgery is effective and relatively safe; however, due to complications, some bands had to be removed in the LAGB group and a relatively high rate of reoperations was observed in the RYGB group.

Levocetirizine is a second-generation nonsedative antihistaminic agent that has been demonstrated to be safe and effective for treating allergic disease. There was only one case report of levocetirizine-induced liver toxicity, but a liver biopsy was not performed. In this article, we present the first case of levocetirizine-induced liver injury with histologic findings. A 48-year-old man was hospitalized with jaundice and generalized pruritus that had developed after 2 months of therapy with levocetirizine for prurigo nodularis. Laboratory findings revealed acute hepatitis with cholestasis. A liver biopsy demonstrated portal inflammation and hepatitis with apoptotic hepatocytes. The patient fully recovered 3 weeks after withdrawing levocetirizine. Although levocetirizine is safe and effective, physicians should be aware of its potential hepatotoxicity.

BACKGROUND/AIMS: Nosocomial infections caused by multidrug-resistant (MDR) Acinetobacter baumannii have become public-health problem. However, few studies have evaluated the control of endemic MDR A. baumannii in Intensive Care Units (ICUs). Therefore, we investigated the effectiveness of antimicrobial stewardship and comprehensive intensified infection control measures for controlling endemic MDR A. baumannii in ICUs at a tertiary care center. METHODS: Carbapenem use was strictly restricted through antimicrobial stewardship. Environmental cleaning and disinfection was performed at least 3 times per day in addition to basic infection control measures. Isolation using plastic curtains and contact precautions were applied to patients who were colonized or infected with MDR A. baumannii. The outcome was measured as the incidence density rate of hospital-onset MDR A. baumannii among patients in the ICUs. RESULTS: The incidence density rate of hospital-onset MDR A. baumannii decreased from 22.82 cases per 1,000 patient-days to 2.68 cases per 1,000 patient-days after the interventions were implemented (odds ratio, 0.12; 95% confidence interval, 0.03 to 0.4; p < 0.001). The mean monthly use of carbapenems also decreased from 134.99 +/- 82.26 defined daily doses per 1,000 patient-days to 94.85 +/- 50.98 defined daily doses per 1,000 patient-days (p = 0.016). CONCLUSIONS: Concomitant implementation of strict antimicrobial stewardship and comprehensive infection control measures effectively controlled endemic MDR A. baumannii in our ICUs within 1 year.

Recently, the number of Korean travelers and workers to malaria-endemic regions has increased, and the number of patients with imported malaria cases has increased as well. In Korea, most cases of imported malaria infections are caused by Plasmodium falciparum and P. vivax. Only one report of imported P. malariae infection has been published thus far. Here, we describe a case of imported P. malariae infection that was confirmed by peripheral blood smear and nested PCR targeting the small subunit ribosomal RNA (SSU rRNA) gene. A 53-yr-old man, who had stayed in the Republic of Guinea in tropical West Africa for about 40 days, experienced fever and headache for 3 days before admission. The results of rapid malaria test using the SD Malaria Antigen/Antibody Kit (Standard Diagnostics, Korea) were negative, but Wright-Giemsa stained peripheral blood smear revealed Plasmodium. To identify the Plasmodium species and to examine if the patient had a mixed infection, we performed nested PCR targeting the SSU rRNA gene. P. malariae single infection was confirmed by nested PCR. Sequence analysis of the SSU rRNA gene of P. malariae showed that the isolated P. malariae was P. malariae type 2. Thus, our findings suggest that when cases of imported malaria infection are suspected, infection with P. malariae as well as P. falciparum and P. vivax should be considered. For the accurate diagnosis and treatment of imported malaria cases, we should confirm infection with Plasmodium species by PCR as well as peripheral blood smear and rapid malaria antigen test.

Smith-Lemli-Opitz syndrome (SLOS) is a rare autosomal recessive disorder caused by 7-dehydrocholesterol reductase deficiency. The characteristic clinical features are syndactyly of the second and third toes, facial dysmorphism, multiple malformations, and intellectual disability. Few cases of SLOS have been reported in Korea. We observed a male patient with SLOS who presented with typical facial features, undescended testes, microcephaly, bilateral syndactyly of the second and third toes, and cardiac defects, including patent ductus arteriosus and atrial septal defect. Mutation analysis of the DHCR7 gene identified compound heterozygous mutations of c.907G>A (p.Gly303Arg) and c.1055G>A (p.Arg352Gln). In a review of the literature, c.1054C>T (p.Arg352Trp) was the most common mutation reported in Far East Asian countries. This report describes the clinical features, biochemical data, molecular characteristics, and clinical outcome of a Korean patient with SLOS.

BACKGROUND/AIMS: During endoscopic retrograde cholangiopancreatography (ERCP), all efforts should be made to be aware of radiation hazards and to reduce radiation exposure. The aim of this study was to investigate the status of radiation protective equipment and the awareness of radiation exposure in health care providers performing ERCP in Korean hospitals. METHODS: A survey with a total of 42 questions was sent to each respondent via mail or e-mail between October 2010 and March 2011. The survey targeted nurses and radiation technicians who participated in ERCP in secondary or tertiary referral centers. RESULTS: A total of 78 providers from 38 hospitals responded to the surveys (response rate, 52%). The preparation and actual utilization rates of protective equipment were 55.3% and 61.9% for lead shields, 100% and 98.7% for lead aprons, 47.4% and 37.8% for lead glasses, 97.4% and 94.7% for thyroid shields, and 57.7% and 68.9% for radiation dosimeters, respectively. The common reason for not wearing protective equipment was that the equipment was bothersome, according to 45.7% of the respondents. CONCLUSIONS: More protective equipment, such as lead shields and lead glasses, should be provided to health care providers involved in ERCP. In particular, the actual utilization rate for lead glasses was very low.

PURPOSE: We investigated the change in serum total immunoglobulin E (IgE) and allergen-specific IgE according to allergic diseases and age. METHODS: Allergic markers of children under 18 years of age with allergic diseases for the last 5 years were collected from 12 hospitals nationwide. The total data was 9,710. Data about levels of serum total IgE and allergen-specific IgE to 15 common allergens were collected. RESULTS: In children with asthma, serum total IgE was higher in older age than in younger age until age 7 to 12 years, at which time the level was highest (paper radioimmunosorbent test, 526.7 IU/mL; UniCAP, 339.9 IU/mL). The level was lower in older age than that during younger age. This change was similar to that in children with allergic rhinitis and atopic dermatitis. The level was highest at ages 7 to 12 years in children with allergic rhinitis, and at age 10 to 12 years in children with atopic dermatitis. In children with both asthma and allergic rhinitis, as well as in children with all three diseases, the change in serum total IgE was similar to that of children with an isolated disease. The highest level in children with all three diseases was higher than that in children with an isolated disease. The analysis of allergen-specific IgE positivity showed that food allergens were dominant before the age of 2 years, and that aeroallergens such as house dust mites were dominant. CONCLUSION: Serum total IgE in Korean children with allergic diseases was higher in older age than in younger age until the ages of 7 to 12 years, and then the change in total IgE by age was the opposite.

The efficacy and safety of ertapenem, 1 g once daily, were compared with that of ceftriaxone, 2 g once daily, for the treatment of adults with acute pyelonephritis (APN) and complicated urinary tract infections (cUTIs) in a prospective, multicenter, double-blinded, randomized study. After > or = 3 days of parenteral study therapy, patients could be switched to an oral agent. Of 271 patients who were initially stratified by APN (n = 210) or other cUTIs (n = 61), 66 (48.9%) in the ertapenem group and 71 (52.2%) in the ceftriaxone group were microbiologically evaluable. The mean duration of parenteral and total therapy, respectively, was 5.6 and 13.8 days for ertapenem and 5.8 and 13.8 days for ceftriaxone. The most common pathogen was Escherichia coli. At the primary efficacy endpoint 5-9 days after treatment, 58 (87.9%) patients in the ertapenem group and 63 (88.7%) in the ceftriaxone had a favorable microbiological response. When compared by stratum and severity, the outcomes in the two groups were equivalent. The frequency and severity of drug-related adverse events were generally similar in both treatment groups. The results indicate that ertapenem is highly effective and safe for the treatment of APN and cUTIs.
