Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

Background/Aim: The use of oral branched chain amino acid (BCAA) for enriched supplement in liver cirrhotic patients is increasing now. This study aimed to examine the effects of BCAA as well as factors associated with the effectiveness to in crease serum albumin concentration. Methods: We reviewed retrospectively medical records of cirrhotic patients who received oral BCAA from January 2004 to December 2012 at Keimyung University Dongsan Hospital . We analyzed the changes of serum albumin concentration after use of oral BCAA and several factors which affected to the effectiveness of oral BCAA. Results: Total 89 patients were included (64 men; mean age, 63.0 ± 8.7 years). Hepatitis B (57.3%), alcohol (15.7%), hepatitis C (14.6%), and others (12.4%) were the causes of liver cirrhosis. Patients with Child-Pugh class A, B, and C were 28.1, 42.7, and 29.2%. Patients were treated with daily oral BCAA (mean dose ± standard deviation, 8.76 ± 2.25 mg/day; median follow-up period, 95 days). 1. Increased albumin group after use of oral BCAA were 27 and non-increased groups were 62 patients. 2. Antiviral therapy was used in patients with hepatitis B (33.3%) during oral BCAA treatment. Antiviral therapy in patients with hepatitis B (80.0% vs. 55.6%; P=0.123) was not significant difference with albumin level after oral BCAA treatment. 3. According to univariate and multivariate analysis, Patients with CP class A or B (OR, 3.611 ; 95 % CI, 1.168-11.169; P=0.026), initial eunatremia (OR, 6.298 ; 95 % CI, 2.064-19.214 ; P=0.001) were increased albumin concentration after oral BCAA treatment. Conclusion: Oral BCAA in patients with liver cirrhosis is effective both as compensated and uncompensated. Oral BCAA effectively increased serum albumin in cirrhotic patients with CP A or B than C. So, early administration of oral BCAA in cirrhotic patients seemed to be needed for better life quality.

HCV, Acute, LT : Significance of Homeostasis Model Assessment-Insulin Resistance Level to Assess Insulin Resistance in Chronic Hepatitis C Patients

( Jae Hyuk Choi ),( Woo Jin Chung ),( Yu Jin Lee ),( Yu Jin Kang ),( Jung Min Lee ),( Eun Sung Choi ),( Sang Min Lee ),( Byoung Kuk Jang ),( Jae Seok Hwang ),( Eun Soo Kim ),( Kyung Sik Park ),( Kwang 대한간학회 2013 춘·추계 학술대회 (KASL) Vol.2013 No.1

Background/Aim: Homeostasis model assessment-insulin resistance (HOMA-IR) is commonly used for assessment of insulin resistance (IR) and IR is associated with chronic hepatitis C (CHC) virus infection. Recently, several study presented data about irrelevance between HOMA-IR and IR. This study aimed to examine the significance of HOMA-IR as representative of IR. Methods: We retrospectively reviewed data from CHC patients who receive standard of care (SOC) from September 2009 to March 2013 at Keimyung University Dongsan Hospital. We analyzed the changes of HOMA-IR score before treatment, at the time of end of treatment and at 6 months after treatment. Results: 53 patients were included (26 men; mean age, 51 ± 10.10 years) for this study. The prevalence of genotype 1a, 1b, 2a, 2b, and 3a were 1.9%, 35.8%, 54.7%, 3.8%, and 3.8%. Before treatment, initially high HOMA-IR group (>2) was 25 patients (47.2%). 1. There were no significant difference of ETR (83% vs. 92.9%, P=0.404) and SVR rate (87.5% vs. 96.0%, P=0.505) in initially high (>2) vs low (≤2) HOMA-IR groups. 2. There were no significant differences of ETR and SVR according to changes of HOMA-IR level between before and after treatment (high to high vs. high to low vs. low to high vs. low to low HOMA-IR; 23.4%, 21.3%, 6.4%, 48.9%, P=0.750 at ETR, and 13.2%, 23.7%, 7.9%, 55.3%, P=0.424 at SVR). 3. Initial HOMAIR levels had no significant differences between ETR group and non-ETR group (3.30 ± 6.29 and 2.99 ± 1.90; P=0.795), and between SVR group and non-SVR group (2.33 ± 2.90 and 3.34 ± 2.77; P=0.795). Conclusion: HOMA-IR levels were not inversely correlated or predicted of SVR after SOC for CHC patients. So, another assessing modalities such as hyperinsulinaemic euglycaemic clamp may be needed to assess IR in CHC patients.

Background/Aims: After endoscopic treatment of peptic ulcer bleeding, rebleeding occurs in 15 to 20 percent of patients. We investigated the factors predicting the failure of initial endoscopic treatment in patients with peptic ulcer bleeding and the usefulness of repeated endoscopic treatment in peptic ulcer patients with rebleeding after initial endoscopic treatment. Methods: Clinical data were retrospectively collected from 376 patients (311 males and 65 females, mean age 53.9 years) with peptic ulcer bleeding between June 1995 and May 1999. Results: Of 376 patients, rebleeding after initial endoscopic treatment occurred in 50 patients (13.3%). Eight patients who failed to initial endoscopic hemostasis underwent operation immediately. The presence of major stigmata on endoscopy (p=0.001) and shock at admission (p=0.001) were two significantly independent factors predictive of rebleeding after initial endoscopic treatment. Among the patients with rebleeding, repeated endoscopic treatment was successful in 26 patients (61.9%), but 16 patients (38.1%0 underwent salvage surgery due to the failure of hemostasis. Patients who did not respond to endoscopic retreatment were more likely to have ulcers ≥2 cm in diameter (p=0.027). Conclusions: Repeated endoscopic treatment can reduce the need for surgery. Ulcer size ≥2cm is an independent factor in predicting the failure of repeated endoscopic treatment in peptic ulcer patients with rebleeding. Therefore, surgery should be considered in the case.

Purpose: Enterovirus is the most common cause of aseptic meningitis, and there are many different serotypes of enteroviruses that cause diverse clinical symptoms. This study compared the clinical characteristics of childhood enteroviral meningitis in different age groups and viral serotypes. Methods: Patients younger than 18 years who were diagnosed with aseptic meningitis in the Pediatric Department of Chonnam National University Hospital from January 2008 to December 2014 were enrolled. We retrospectively reviewed their clinical records. Results: Enterovirus was tested in 66.6% of 655 patients with aseptic meningitis, with the testing being more frequent in younger patients (P<0.001). Enterovirus was present in 69.7% of patients, and able to be serotyped in 52.6%. Headache and irritability were more frequent in older children, whereas respiratory and neurologic symptoms were more common in infants and early childhood (P<0.05). Marked pleocytosis in the cerebrospinal fluid (CSF) was more frequent in neonates and infants, whereas marked increases in CSF proteins were more common in adolescents (P<0.05). The most common enterovirus was coxsackievirus B1 (CB1) in neonates and enterovirus 71 (EV71) in infancy and early childhood. Compared with the mean frequencies of symptoms in enteroviral meningitis, less frequent symptoms were fever in echoviruses (Es), headache or irritability in CBs and EV71, and vomiting in CBs. Neurologic symptoms were frequent in EV71 (P<0.05). Marked CSF pleocytosis was more frequent in CBs and Es (P<0.05). Conclusion: The clinical characteristics and laboratory findings of childhood enteroviral meningitis differ with age and viral serotype. In addition, the prevalent enteroviral serotypes differ with age.

본 연구에서는 폐플라스틱의 재활용 현황을 조사한 후 재활용을 저해하는 요인들을 분석하였다. 폐플라스틱의 재활용율 을 저해하는 요인들은 토지와 인력확보의 어려움 플라스틱의 종류별 재질표시 미흡 경제적 유인책인 예치금과 부담금의 요율의 부적합 등으로 나타났다 LCA 방법을 통한 폐플라스틱의 재활용성을 분석하기 위하여 PET 재질의 물질 재활용 공 정에 대한 LCA를 수행하였다. PEr를 처녀원료로만 제조하는 것보다 재생 PET원료를 함께 사용했을 때의 환경영횡t은 오 존층 파괴를 제외한 나머지 영향범주에서 (-)값으로 나타나 보다 환경친화적임이 밝혀졌다. 특히 지구온난화 영향의 범주 에서 환경삭감 효과(avoided impact)가 크게 나타났다. 폐플라스틱의 재자원화를 활성화 하려면 먼저 재활용품에 대한 분 리수거 제도가 확립되어야 하고 재활용 가능표시가 명확해야 하며 소비자들이 이를 쉽게 이해할 수 있어야 한다. 또한 생 산자 예치금 및 소비자 예치금의 요율이 합리적이어야 하며 재활용에 대한 인프리구축, 정보체계 확립, 공공교육을 통한 시민들의 협조가 필요하다. 1n the study, current status of waste plastic recycling was investigated. Some factors to obstruct recycling of waste plastic was analyzed. These factors include the difficulry of obtairúng location anfd man power, unclear marking of recyclable plastic and ineffìcient rate in producer and consumer deposit system. Life cycle assessment(LCA ) study was performed to investigate the environmental impact of waste plastic(PET) recycling. When the recycled raw plastic material is used together with the virgin raw plastic material, all the environmental impact showed (-) value except ozone depletion impact category. The environmental avoided impact was the greatest in the global warming impact category. For active promotion of recycling activiry, source separation system of waste plastic should be established fìrst of all. Also, marking system of the recycling waste plastic should be made more clear so that consumers can understand it easily. Other strategies include the determination of decent rate for producer and consumer deposit system, establishment of infrastructure and information system for waste plastic recycling and citizen’s cooperation through intensive public education.
