Although rare, hepatic artery aneurysms are associated with a high morbidity and mortality, necessitating a prompt diagnosis. A significant proportion of hepatic artery aneurysms are pseudoaneurysms, and the major risk factors of which have already been identified in previous literatures. Presentation can be variable, but diagnosis almost relies entirely on computed tomography and digital subtraction angiography. The endovascular approach has progressively become the preferred option due to its better performance when compared to the traditional surgical approach. However, formulation of an endovascular treatment plan for these lesions remains difficult as multiple factors should be considered to identify the best endovascular treatment modality. Five cases of pseudoaneurysm due to recent Whipple operation, hepatobiliary infections, and underlying malignancy are presented in this article to illustrate the effectiveness and complexity of endovascular treatment in this disease entity.

The COVID-19 pandemic resulted in 5 consecutive Movement Control Orders (MCOs) in Malaysia in an attempt to flatten the epidemiological curve, with a reduction of cases. This study aims to use statistical analysis to assess whether the decisive public health interventions in the MCO were efficacious. Three statistical tests were employed: Mann-Kendall trend analysis; one way between groups ANOVA; and Pearson correlation test. Results demonstrated significant differences between the second block, MCO 3-5, compared to MCO 1-2. Johor and Selangor states experienced significant increase in early MCO, whereas Sarawak and Selangor states experienced significant decrease by MCO 3-5. The northern border states of Kedah, Perlis and Kelantan, had caseloads stabilised to zero by MCO 4/MCO 5. This study demonstrates that the MCO was effective within the target of twice the two-week incubation period of COVID-19, with cases from community transmission and importation through the air and southern land borders. Selangor and Sarawak had higher cases in early MCO due to situational factors. In conclusion, MCO has been efficacious, with different states attaining different levels of case reduction due to individualised reasons.

PURPOSE: The treatment strategy for elderly patients older than 80 years with diffuse large B-cell lymphoma (DLBCL) has not been established because of poor treatment tolerability and lack of data. MATERIALS AND METHODS: This multicenter retrospective study was conducted to investigate clinical characteristics, treatment patterns and outcomes of patients older than 80 years who were diagnosed with DLBCL at 19 institutions in Korea between 2005 and 2016. RESULTS: A total of 194 patients were identified (median age, 83.3 years). Of these, 114 patients had an age-adjusted International Prognostic Index (aaIPI) score of 2-3 and 48 had a Charlson index score of 4 or more. R-CHOP was given in 124 cases, R-CVP in 13 cases, other chemotherapy in 17 cases, radiation alone in nine cases, and surgery alone in two cases. Twenty-nine patients did not undergo any treatment. The median number of chemotherapy cycles was three. Only 37 patients completed the planned treatment cycles. The overall response rate from 105 evaluable patients was 90.5% (complete response, 41.9%). Twentynine patients died due to treatment-related toxicities (TRT). Thirteen patients died due to TRT after the first cycle. Median overall survival was 14.0 months. The main causes of death were disease progression (30.8%) and TRT (27.1%). In multivariate analysis, overall survival was affected by aaIPI, hypoalbuminemia, elevated creatinine, and treatment. CONCLUSION: Age itself should not be a contraindication to treatment. However, since elderly patients show higher rates of TRT due to infection, careful monitoring and dose modification of chemotherapeutic agents is needed.

PURPOSE: A flow diverter (FD) is an effective treatment option for intracranial aneurysms. The Flow Re-direction Endoluminal Device (FRED) is a relatively new flow diverter with a unique dual-layer design. We report our experience and short-term results with the FRED. MATERIALS AND METHODS: We did a retrospective review of all consecutive cases in which the FRED was used to treat intracranial aneurysms at a single institution from March 2014 till December 2015. Clinical parameters, aneurysm characteristics, technical results and short-term outcomes were reviewed. RESULTS: Eleven intracranial aneurysms were treated with the FRED in 11 patients. The technical device deployment success rate was 100%. Immediate reduction in intra-aneurysmal flow after deployment was noted in 10 cases. The aneurysm occlusion rate at 6 months was 75%. There was 1 complication of in-stent thrombosis immediately after deployment. There was no side branch occlusion, delayed aneurysm rupture, stroke, or intraparenchymal haemorrhage. There was no neurological deficit, morbidity, or mortality. CONCLUSION: The FRED is a new FD. It has shown to be safe and effective in our series. The unique dual-layer design of the device renders it to have technical advantages over other FDs. The 6-month aneurysm occlusion rate and complication profile of FRED are similar to other FDs.

Facioscapulohumeral muscular dystrophy (FSHD) presents a muscular weakness in the face, shoulder girdle, and legs. In addition, bilateral, progressive, high-frequency sensorineural hearing loss (SNHL) can be expressed. A 3-year-old boy visited with bilateral facial paralysis and bilateral hearing loss. Audiological evaluations revealed bilateral, progressive, sloping SNHL and bilateral hearing aids was used for more than 3 years. Cochlear implantation was carried out on left side when he was 6 years old and on right side when he was 7 years old. Seven months after cochlear implantation on left side, his shoulder muscle weakness was found and the genetic analysis showed decreased D4Z4 repeat size in 4qA allele confirming a diagnosis of FSHD. After auditory rehabilitation using electroacoustic stimulation, his hearing and speech perception were much improved. This case suggests that cochlear implantation can be beneficial in patients with SNHL associated with FSHD.

This study assessed the ability of the Sequential Organ Failure Assessment (SOFA) and Acute Physiology, Chronic Health Evaluation (APACHE) II scoring systems, as well as the Simplified Acute Physiology Score (SAPS) II method to predict group mortality in intensive care unit (ICU) patients who were poisoned with organophosphate. The medical records of 149 organophosphate poisoned patients admitted to the ICU from September 2006 to December 2012 were retrospectively examined. The SOFA, APACHE II, and SAPS II were calculated based on initial laboratory data in the Emergency Department, and during the first 24 hr of ICU admission. The probability of death was calculated for each patient based on the SOFA score, APACHE II score, and SAPS II equations. The ability to predict group mortality by the SOFA score, APACHE II score, and SAPS II method was assessed using two by two decision matrices and receiver operating characteristic (ROC) curve analysis. A total of 131 patients (mean age, 61 yr) were enrolled. The sensitivities, specificities, and accuracies were 86.2%, 82.4%, and 83.2% for the SOFA score, respectively; 65.5%, 68.6%, and 67.9% for the APACHE II scoring system, respectively; and 86.2%, 77.5%, and 79.4% for the SAPS II, respectively. The areas under the curve in the ROC curve analysis for the SOFA score, APACHE II scoring system, and SAPS II were 0.896, 0.716, and 0.852, respectively. In conclusion, the SOFA, APACHE II, and SAPS II have different capability to discriminate and estimate early in-hospital mortality of organophosphate poisoned patients. The SOFA score is more useful in predicting mortality, and easier and simpler than the APACHE II and SAPS II.

BACKGROUND/AIMS: Helicobacter pylori infection is a recognized cause of chronic gastritis, peptic ulcer and gastric adenocarcinoma. However, both positive and negative associations with colorectal neoplasia have been reported. The aim of this study was to determine whether H. pylori infection is associated with an increased risk of colonic neoplasia in a Korean population. METHODS: We examined 1,590 subjects (1,297 men and 293 women) who underwent colonoscopy and serologic testing for IgG antibodies against H. pylori at the Health promotion Center in Kangbuk Samsung Hospital and at Samsung Medical Center. We compared the prevalence of colonic neoplasia in the seropositive subjects with that of the seronegative subjects. RESULTS: The overall prevalence of H. pylori in our study population was 56.2%. There were no significant differences of the baseline characteristics between the two groups. There was no statistically significant difference in the prevalence of colonic neoplasia between the seropositive group and the seronegative group (p=0.090). CONCLUSIONS: These findings suggest that there is no significant association between H. pylori infection and colonic neoplasia.

BACKGOUND: The present study was undertaken to determine the effect of remifentanil on the bispectral index (BIS) during intubation under TIVA (total intravenous anesthesia) using propofol. METHODS: In this prospective, randomized, double-blind study, 80 healthy patients aged 18~60 years undergoing elective surgery were investigated. Anesthesia was induced using propofol (target effect-site concentration 4microgram/ml). After the loss of consciousness, rocuronium (0.9 mg/kg) and remifentanil was infused. The patients in the R group were infused with remifentanil using a target effect-site concentration of 4 ng/ml, and patients in the P group were infused with saline. The BIS value, mean arterial pressure (MAP) and heart rate (HR) were measured before induction, before remifentanil infusion and before and after tracheal intubation. RESULTS: The BIS value remained constant after intubation in the two groups. The MAP and HR increased significantly after intubation in the two groups, but the degree of increase of MAP and HR was less in group R than in group P significantly. CONCLUSIONS: We suggest that the BIS value is not affected by the administration of remifentanil during intubation under TIVA using propofol.

BACKGROUND/AIMS: It has been reported that the risk of gastric polyp is increased in various colonic polyposis syndromes or in series of patients with sporadic colonic polyps. However, there are only a few large case controlled studies of colon cancer incidence in gastric cancer patients who underwent colonoscopy. The aims of this study were to determine the incidence of colorectal neoplasm and to evaluate the necessity of colonoscopic surveillance in patients with gastric cancer. METHODS: We performed colonoscopy in 105 patients with gastric cancer who agreed to undergo colonoscopy before or after 6 months from gastric resection between January 2002 and December 2004 in Kangbuk Samsung hospital. As a control group, 269 consecutive, age and sex matched patients without gastric neoplasm on gastroscopy who underwent colonoscopy within 6 months for the evaluation of various gastrointestinal symptoms during the year 2004 were included. Endoscopic reports and pathological results were reviewed retrospectively. RESULTS: In the patient group, adenomatous polyps were diagnosed in 24/105 patients (22.9%) and colorectal adenocarcinoma in 10/105 patients (9.5%). In the control group, adenomatous polyps were diagnosed in 78/269 patients (29.0%) and colorectal adenocarcinoma in 2/269 patients (0.7%). The incidence of colorectal adenocarcinoma between the patient group and control group showed significant differences (odds ratio 11.04, p=0.003). CONCLUSIONS: The risk of colorectal adenocarcinoma increases significantly in patients with gastric cancer. We suggest that the patients with gastric cancer might carry a high risk for colorectal cancer whom require surveillance colonoscopy.

BACKGROUND/AIMS: Bamboo joint-like (BJL) appearance is an endoscopic finding characterized by swollen longitudinal folds transversed by erosive fissures or linear furrows on the lesser curvature side of gastric body and cardia. It has been reported to be associated with Crohn's disease (CD). This study was aimed to evaluate the incidence of BJL appearance in Korean patients with CD. METHODS: From January to December in 2005, we performed esophagogastroduodenoscopy (EGD) in patients diagnosed as CD and ulcerative colitis (UC) in our hospital. Non-inflammatory bowel disease (IBD) subjects with upper gastrointestinal symptoms who underwent EGD were consecutively enrolled during the same period. One endoscopist performed all the endoscopic examinations to avoid inter-observer variation. A dye-spraying technique with 0.4% indigocarmine was used to allow the detection of subtle changes during the endoscopic examination. RESULTS: A total of 21 patients with CD (mean age+/-SD, 40+/-15 yr; M/F, 13/8), 28 patients with UC (42+/-15 yr; 21/7), and 685 non-IBD subjects (49+/-14 yr; 354/331) were enrolled. EGD findings in CD patients were gastric erosions (11/21), chronic superficial gastritis (5/21), chronic atrophic gastritis (1/21), duodenal erosions or ulcers (2/21), and normal (2/21). Incidence of BJL appearance was significantly higher in patients with CD (47.6%, 10/21) than others (UC, 3.6%, 1/28; non-IBD, 0.1%, 1/685) (p<0.0001). Among patients with CD, incidence of BJL appearance was not significantly different according to the sex, status of H. pylori infection, Vienna classification for phenotype, medications or EGD findings. CONCLUSIONS: BJL appearance on the gastric body and cardia can be a diagnostic clue to CD.
