PURPOSE: The purpose of this descriptive, cross-sectional study was to identify the factors affecting health-related quality of life by examining the relationships among posttraumatic stress, health-related work limitations, and family support in firefighters. METHODS: The data were collected from 390 firefighters working in four fire stations located in the G district using self-report questionnaires. The collected data were analyzed using descriptive statistics, t-test, one-way ANOVA along with the Scheffé test, and multiple regression. RESULTS: As per the results of multiple regression analysis, the factors affecting health-related quality of life in firefighters were posttraumatic stress, health-related work limitations, and family support. This model explained 31% of the variance in health-related quality of life (F=30.03, p<.001). CONCLUSION: Considering the findings of this study, there is a need to reduce posttraumatic stress and health-related work limitations and develop family support toward firefighters.

Without significant coronary artery stenosis, ischemic electrocardiographic change including ST segment elevation, segmental wall motion abnormality and elevated serum cardiac-specific markers (creatine kinase-MB, Troponin-T) may develop after central nervous system injuries such as subarachnoid, intracranial or subdural hemorrhage. Misdiagnosing these patients as acute myocardial infarction may result in catastrophic outcomes. By reporting a case of a 55-year old female with subarachnoid hemorrhage mimicking acute ST elevation myocardial infarction, we hope to underline that careful attention of neurologic abnormality is critical in making better prognosis.

Many advances, including the development of antibiotics, the advent of diagnostic techniques and the use of nonsurgical drainage have decreased the mortality rate of pyogenic liver abscess. But, early prompt diagnosis and proper treatment is mandatory in gas-forming pyogenic liver abscess because it may run a fulminating course to death. Gas-forming pyogenic liver abscess mostly occurred to old diabetics. Symptoms of duration are shorter and the prognosis is poorer in the gas-forming than in the non-gas-forming liver abscess. We report three cases of gas-forming pyogenic liver abscess which occurred in old diabetic patients. They were successfully managed by parenteral antibiotics and early percutaneous drainage under sonographic guidance. Early and adequate drainage of pus by pigtail catheter may play a crucial role on the treatment of gas-forming liver abscess.

OBJECTIVES: We conducted this study to investigate the relationship between sleep duration and body mass index (BMI), in Korean children. METHODS: We performed a cross-sectional analysis of data collected on 3,639 boys and girls (aged 7-12) in Daegu, Korea. The data included each child's age, sex, weight, height, extracurricular activities, bedtime, wake-up time, sleep latency, total sleep duration, parents' occupations, and parents' educational levels. The relationship between sleep duration and each variable was examined via analysis of variance (ANOVA). RESULTS: The analysis showed an association between short sleep duration and high BMI. Boys showed a graded inverse relationship between sleep duration and BMI. However, there was no significant corresponding result for girls. In the total sample, hours of computer use, time when the computer was turned off, time when the television was turned off, mother's bedtime, and hours of extracurricular activity were associated with longer sleep duration. No association was found between sleep duration and hours of watching television, child's wake-up time, or educational level of the parents. CONCLUSION: The results of this study show an inverse relationship between a child's sleep duration and BMI;thus, children with shorter sleep duration tend to have higher BMIs.

BACKGROUND/AIMS: Common bile duct (CBD) stones can be removed by endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (EST) in most cases. In addition, surgery or stenting as well as percutaneous transhepatic cholangioscopy (PTCS) with lithotripsy can be used to remove CBD stones also. In this study we evaluated the efficacy of percutaneous removal of CBD stones which could not be removed by per-oral endoscopic method. METHODS: From Jan. 1998 to Sep. 2001, ERCP were tried to remove CBD stones in 395 patients. We reviewed causes of treatment failure through the peroral method and PTCS-results by the medical records and cholangiograms in 15 patients. RESULTS: We successfully removed stones with PTCS in all 15 patients. The reasons for percutaneous approach were previous operation history in 8 (53.3%) and old age in 10 (66.7%). Mean number and size of stone were 4.4 and 17.4 x 13.1 mm, respectively. Complete fragmentation and removal of stones were achieved in a single session in 40%. Mean time to complete removal was 19 days. In 1 patient, bile peritonitis was developed but cured by conservative management alone. CONCLUSIONS: PTCS with or without lithoptripsy is an effective and safe method for the treatment of CBD stones which can not be removed by peroral endoscopic approach.

The migratory thrombophlebitis and thromboembolic disorders of the venous and arterial systems in the setting of malignancy are termed Trousseau's syndrome. The overall incidence of clinical thromboembolic events in patients with cancer has been reported to vary between 1~11%. Pancreatic carcinoma has been associated with the greatest risk of thromboembolic events. Other tumor type also prone to an increased risk of thromboembolic events, including lung, prostate, stomach, acute leukemia and colon cancer. Hypercoagulability associated cancer may result from activation of coagulation, injury to the endothelium, or alteration of blood flow. Unlike other coagulopathies, Trousseau's syndrome may manifest with thromboses in unusal areas, including the upper extremities, face and visceral organs. Neck vein thrombosis associated with distant cancers have been rarely reported. Jugular vein thrombosis associated with gastrc cancer is very rare. We report one case of gastic adenocarcinoma presented as internal jugular vein thrombosis.

Biliary-enteric fistula is a rare disease, and the common causes of biliary-enteric fistula are gallstone, peptic ulcer, malignancy and trauma. It is known that the most common type of biliary-enteric fistula is the cholecysto-duodenal fistula, yet the combination of choledocho-duodeno-colonic fistula is a rare finding. A 78-year-old woman was admitted because she had suffered with right upper quadrant pain, a febrile sense and chills for 2 days. We confirmed the choledocho-duodeno-colonic fistula by performing gastroduodenoscopy, abdominal CT and an upper GI series. So, we report here on an usual case of choledocho-duodeno-colonic fistula, along with a review of the relevant literatures.

OBJECTIVE: The primary aim of this study was to investigate the acute impact of methylphenidate (MPH) on sleep parameters in attention-deficit/hyperactivity disorder (ADHD) children. The second aim was to investigate the different effects of intermediate- and longacting MPH on sleep parameters. The third aim was to test the different effects of dose and age on sleep parameters. METHODS: Ninety-three ADHD children were enrolled and randomized to two different MPH preparations. Baseline and daily sleep diaries were evaluated for four weeks after taking medication. Weekday and weekend bedtimes, wake-up times, sleep latencies and total sleep times were compared by weeks. RESULTS: After taking MPH, there was a significant delay in bedtimes and a significant reduction of total sleep time (TST) both on weekdays and at weekends. There was also a significant delay in wake-up time on weekdays. However, the difference was applied to younger age group children only. There was no difference in changes of TST between metadate-CD and OROS-MPH. There also was no difference in changes of TST with different doses of MPH. CONCLUSION: MPH had negative impacts on sleep among young ADHD children, but different preparations and doses did not affect the result.

OBJECTIVES: The aim of this study was to evaluate the associations of frailty with perceived neighborhood walkability and environmental pollution among community-dwelling older adults in rural areas. METHODS: The participants were 808 community-dwelling men and women aged 65 years and older in 2 rural towns. Comprehensive information, including demographics, socioeconomic status, grip strength, polypharmacy, perceived neighborhood environment (specifically, walkability and environmental pollution), and frailty, was collected from participants using face-to-face interviews conducted between June and August 2018. Perceived neighborhood walkability was measured using 20 items that were selected and revised from the Neighborhood Environment Walkability Scale, the Neighborhood Walkability Checklist from the National Heart Foundation of Australia, and the Physical Activity Neighborhood Environment Survey. The Kaigo-Yobo Checklist was used to assess participants’ frailty. RESULTS: The overall prevalence of frailty in this community-dwelling population was 35.5%. Sex, age, cohabitation status, educational attainment, employment status, grip strength, and polypharmacy were significantly associated with frailty. In the logistic regression analysis, frailty was associated with low perceived neighborhood walkability (adjusted odds ratio [aOR], 0.881; 95% confidence interval [CI], 0.833 to 0.932; p<0.001) and severe perceived neighborhood environmental pollution (aOR, 1.052; 95% CI, 1.017 to 1.087; p=0.003) after adjusting for sex, age, cohabitation status, educational attainment, employment status, monthly income, grip strength, and polypharmacy. CONCLUSIONS More studies are warranted to establish causal relationships between walkability and environmental pollution and frailty.
