Background/Aims: This study aimed to determine changes in endoscopist-driven sedation practices 5 years after the first nationwide survey in 2014 by the Korean Society of Gastrointestinal Endoscopy (KSGE). Methods: A 59-item survey covering current practices was electronically mailed to all members of the KSGE in 2019. Results: In total, 955 (12.8%) out of 7,486 questionnaires were returned. A total of 738 (77.7%) out of 955 respondents attended dedicated sedation education programs. The American Society of Anesthesiologists class was recorded by 464 (51.2%) out of 907 respondents. The recording rate was higher in respondents who completed sedation education (p=0.014) and worked in general or tertiary hospitals (p<0.001). Compared to that reported in the previous survey, the reported use of propofol was higher in 2019. The respondents had higher satisfaction scores for propofol-based sedation compared with midazolam monotherapy (p<0.001). The rates of oxygen supplementation (p<0.001) and oxygen saturation level monitoring (p<0.001) during sedative endoscopy were higher in 2019 than in the previous survey. A total of 876 (98.4%) out of 890 respondents reported a separate recovery bay, and 615 (70.5%) out of 872 respondents reported that personnel were assigned solely to the recovery bay. Conclusions Endoscopist-driven sedation and monitoring practices in 2019 were significantly different than those in 2014. The respondents favored propofol-based sedation and utilized oxygen supplementation and monitoring of O2 saturation more frequently in 2019 than in 2014.

Meralgia paresthetica (MP) is a painful mononeuropathy of the lateral femoral cutaneouse nerve (LFCN) characterized by localized symptoms of numbness, tingling, pain and paresthesia along the anterolateral thigh area. L4 and L5 radiculopathy is set of symptoms that include sharp, burning or shooting pain, which is usually localized to anterolateral leg area and along the dermatomal distribution. When symptoms of MP and lumbar disc disease occur together it is not easy to diagnose MP. We report a case of synchronous post-traumatic MP and radiculopathy due to intervertebral disc herniation at L3–4 and 4–5. A 59-year-old male patient was admitted to the emergency room with symptoms of low back pain with left severe L4, L5 radiculopathy. This patient also complained of numbness and paresthesia in the left anterolateral thigh. After detailed history taking and lateral femoral cutaneouse nerve block, he was diagnosed with MP.

Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths in South Korea. To decrease its mortality rate, its early detection is very important. Screening for HCC detection has been accepted as the management modality for patients with chronic liver disease. Reported herein is a case involving the marked rapid growth of HCC detected at an advanced stage in a screening test with a 3 months interval. A 49-year-old male patient with chronic hepatitis B was admitted to the hospital due to a liver mass detected on CT scan. The patient underwent a first CT scan 3 months earlier, and no tumor was detected. Follow-up CT scan was performed and showed a 9.1 cm HCC with portal vein thrombosis. Percutaneous liver biopsy was performed, and the diagnosis of hepatocellular carcinoma was confirmed. In the pertinent guidelines, the recommended screening interval for HCC is 6-12 months, but the screening interval and additional diagnostic methods should be considered due to the variation in the HCC growth rate according to the patient's clinical characteristics.

BACKGROUND/AIMS: Early intestinal mucosal damage plays an important role in severe acute pancreatitis (AP). Previous studies have shown that intestinal permeability (IP), serum endotoxin and cytokines contribute to the early intestinal barrier dysfunction in AP. This study explored the predictive capacity of IP, endotoxemia and cytokines as prognostic indicators in AP patients. METHODS: Eighty-seven AP patients were included in the study. The patients were classified into three groups according to the Balthazar computed tomography severity index (CTSI). We compared the biochemical parameters, including IP, serum endotoxin level and cytokine level among the three groups. The associations of IP with serum endotoxin, cytokines, CTSI, and other widely used biochemical parameters and scoring systems were also examined. RESULTS: IP, serum endotoxin, interleukin (IL-6) and tumor necrosis factor (TNF)-alpha had a positive correlation with the CTSI of AP. Endotoxin, IL-6, TNF-alpha, CTSI, the Ranson/APACHE II score, the duration of hospital stay, complications and death significantly affect IP in the AP patients. CONCLUSIONS: We believe that IP with subsidiary measurements of serum endotoxin, IL-6 and TNF-alpha may be reliable markers for predicting the prognosis of AP. Further studies that can restore and preserve gut barrier function in AP patients are warranted.

BACKGROUND/AIMS: Nonselective beta-blockers (NSBBs), such as propranolol, reportedly exert a pleiotropic effect in liver cirrhosis. A previous report suggested that survival was higher in patients receiving adjusted doses of NSBBs than in ligation patients. This study investigated whether low-dose NSBB medication has beneficial effects in patients with liver cirrhosis, especially in terms of overall survival. METHODS: We retrospectively studied 273 cirrhotic patients (199 males; age 53.6+/-10.2 years, mean+/-SD) who visited our institution between March 2003 and December 2007; follow-up data were collected until June 2011. Among them, 138 patients were given a low-dose NSBB (BB group: propranolol, 20-60 mg/day), and the remaining 135 patients were not given an NSBB (NBB group). Both groups were stratified randomly according to Child-Turcotte-Pugh (CTP) classification and age. RESULTS: The causes of liver cirrhosis were alcohol (n=109, 39.9%), hepatitis B virus (n=125, 45.8%), hepatitis C virus (n=20, 7.3%), and cryptogenic (n=19, 7.0%). The CTP classes were distributed as follows: A, n=116, 42.5%; B, n=126, 46.2%; and C, n=31, 11.4%. Neither the overall survival (P=0.133) nor the hepatocellular carcinoma (HCC)-free survival (P=0.910) differed significantly between the BB and NBB groups [probability of overall survival at 4 years: 75.1% (95% CI=67.7-82.5%) and 81.2% (95% CI=74.4-88.0%), respectively; P=0.236]. In addition, the delta CTP score did not differ significantly between the two groups. CONCLUSIONS: Use of low-dose NSBB medication in patients with liver cirrhosis is not indicated in terms of overall and HCC-free survival.

BACKGROUND/AIMS: The benefits and risks of concomitant immunomodulators with infliximab maintenance therapy in patients with luminal Crohn's disease (CD) have not been adequately evaluated. We studied the influence of immunomodulator discontinuation in patients in remission with infliximab therapy through a restrospective case-control study. METHODS: Medical records of 37 patients with luminal CD who received infliximab at four medical centers were retrospectively analyzed. We compared clinical and follow-up data of patients who were treated with infliximab alone with that of patients with combination therapy. RESULTS: Among 37 patients, 31 (83.7%) were treated with infliximab plus azathioprine and six (16.2%) were treated with infliximab alone. Of the 31 patients receiving combination maintenance therapy, 26 (83.9%) were in complete remission after 12 months, as compared with five of six patients (83.3%) receiving infliximab alone. No significant difference was observed in remission rate between two groups (P=0.735). In total, 16.1% of patients in combination therapy and 16.7% in infliximab alone group reported side effects (P=1.000), but serious adverse events such as reactivation of tuberculosis were noted in only one patient in combination therapy group. CONCLUSIONS: Concomitant immunomodulators did not improve efficacy in patients with luminal CD who received scheduled infliximab maintenance.

BACKGROUND: Microalbuminuria (MA) is independent predictor of cardiovascular disease and it cause mortality regardless of the presence of diabetes (DM) and hypertension (HTN). However, few published studies on this topic have been reported in Korea. Therefore, we investigated the MA prevalence and relationship between MA, insulin resistance and cardiovascular risk factor. METHODS: A total of 5,915 (3,053 men and 2,852 women) health screen examinees were enrolled in this study. We measured the anthropometric and biochemical parameters of the atherogenic indexes. RESULTS: The MA prevalence was 7.7% in all participants. The prevalence of MA in the men and women was 9.5% and 5.7%, respectively. Elevated levels of serum fasting glucose, serum fasting insulin, HOMA index, total cholesterols, LDL cholesterol, TG, Body Mass Index (BMI) and the systolic and diastolic blood pressure were significantly associated with MA. The results of multiple logistic regression analysis about MA showed that frequent drinking, low BMI, newly diagnosed DM and elevated levels of HOMA index and blood pressure were significantly associated with MA prevalence. Also, excluding newly diagnosed diabetic and hypertensive subjects, the MA prevalence was 5.7% (6.9% in men, 4.7% in women) and in multiple logistic regression analysis, the MA prevalence significantly increased in the individuals with pre-HTN rather than in the normotensives. CONCLUSIONS: The MA prevalence was 7.7% in all subjects. Except the newly diagnosed diabetic and hypertensive subjects, it was 5.7%. The MA prevalence was significantly increased in the individuals with pre-HTN rather than in the normotensives and MA was related with insulin resistance.

BACKGROUND AND OBJECTIVES: Recent studies have demonstrated that lipoprotein (a) [Lp(a)] plays an important role in atherothrombogenesis and to be associated with an increased risk for cardiovascular disease. SUBJECTS AND METHODS: We evaluated the distribution of Lp (a) and its association with cardiovascular risk factors, by conducting a cross sectional survey of 14,516 apparently healthy Koreans. The study group consisted of 8,007 men and 6,509 women, aged 20 years and over. RESULTS: The mean, medium and 75th percentile Lp (a) levels were 20.1, 13.2 and 23.8 mg/dL, respectively. The distribution of Lp (a) was highly skewed toward a lower level. The Lp (a) level was positively associated with age (p<0.001) and low density lipoprotein (LDL)(p<0.001). The body mass index (BMI)(p=0.006), log (triglyceride)(p<0.001) and alcohol consumption more than 3 times per week (p<0.047) were inversely related to the Lp (a) level. However, no relationship was seen with smoking, gender, exercise, homeostatic model assessment-insulin resistance (HOMA-IR) and high sensitivity C reactive protein (hsCRP). CONCLUSION: The Lp (a) level was positively associated with age and low density lipoprotein (LDL). The body mass index (BMI) and log (triglyceride) were inversely related to the Lp (a) level. However, the association between Lp (a) and cardiovascular disease in the general Korean population should be confirmed via large scale prospective cohort studies.

BACKGROUND: Iron is essential for life, but iron overload state cause potentially fatal health risk. There is growing evidence that only mildly increased amounts of hepatic iron can be damaging, particulary if combined with other hepatotoxic factors such as alcoholic or chronic viral hepatits B,C. The aim of this study was to assess the serum iron status of patients with various forms of hepatitis and cirrhosis of liver and to determine the correlation between the degree of hepatocyte damage (expressed as ALT activity) and status of serum iron parameters. METHODS: Our research involved 107 patients (69 male ranging in age from 27-67 and 38 female ranging in age from 32-62) diagnosed with chronic viral hepatitis B or type C, alcoholic hepatitis or cirrhosis of the liver. Serum iron parameters such as serum iron, ferritin, TIBC, and aminotransferase measured as necroinflammatory activity in Chronic hepatitis. RESULTS: There was no difference s-iron level between chronic hepatitis and cirrhosis but, significantly higher in alcoholic hepatitis and cirrhosis than viral hepatitis and cirrhosis respectively. s-Ferritin level was significantly higher in cirrhosis than hepatits group, and more higher in alcoholic hepatitis and cirrhosis than viral hepatitis and cirrhosis respectively. In chronic hepatitis groups, there are significant correlation between ALT and s-ferritin level regardness of etiology. CONCLUSION: Serum iron overload state was prominent in alcoholic hepatitis and cirrhosis than viral hepatitis and cirrhosis. High serum ferritin level can predict hepatocyte damage in chronic hepatitis.

Four Years Reports of "Journal of Korean Neuropsychiatric Association" during 2001 to 2005 were evaluated by 18 Editorial Board of Korean Neuropsychiatric Association. We investigated the articles to specific fields and rejection rate etc. by different section chiefs. Although several problems concerning review time duration and rejection guideline issues indicated but generally all reviewer processes proved relatively clear and concise criteria. Through these objective and systematic evaluation processes, "Journal of Korean Neuropsychiatric Association" will develop a good journal.
