OBJECTIVES: This study aimed to investigate the psychosocial characteristics of functional gastrointestinal disorder (FGID) in patients with psychiatric disorders. METHODS: This study was conducted with 144 outpatients visiting the psychiatric clinic at a university hospital. FGIDs were screened according to the Rome III questionnaire-Korean version. Demographic factors were investigated, and psychosocial factors were evaluated using the Hospital Anxiety Depression Scale, Patient Health Questionnaire-15, Childhood Trauma Questionnaire-Korean, and State-Trait Anger Expression Inventory. Chi-squared test and student's t-test were used as statistical analysis methods. RESULTS: There were differences in education level between two groups divided according to FGID status (χ²=10.139, p=0.017). Comparing the psychiatric disorder by FGID group, irritable bowel syndrome (IBS) group showed significant differences (χ²=11.408, p=0.022). According to FGID status, IBS group showed significant differences for anxiety (t=−3.106, p=0.002), depressive symptom (t=−2.105, p=0.037), somatic symptom (t=−3.565, p < 0.001), trait anger (t=−3.683, p < 0.001), anger-in (t=−2.463, p=0.015), and anger-out (t=− 2.355, p=0.020). Functional dyspepsia group showed significant differences for anxiety (t=−4.893, p < 0.001), depressive symptom (t=−3.459, p < 0.001), somatic symptom (t=−7.906, p < 0.001), trait-anger (t=−4.148, p < 0.001), state-anger (t=−2.181, p=0.031), anger-in (t=−2.684, p=0.008), and anger-out (t=−3.005, p=0.003). Nonerosive reflux disease group showed significant differences for anxiety (t=−4.286, p < 0.001), depressive symptom (t=−3.402, p < 0.001), somatic symptom (t=−7.162, p < 0.001), trait anger (t=−2.994, p=0.003), state anger (t=−2.259, p=0.025), anger-in (t=−2.772, p=0.006), and anger-out (t=−2.958, p=0.004). CONCLUSIONS: Patients with psychiatric disorders had a high prevalence of FGID, and various psychosocial factors contributed to such differences. Therefore, the psychiatric approach can offer better understandings and treatments to patients with FGID.

OBJECTIVES: The purpose of this study was to investigate the characteristics of psychosocial factors related to functional dyspepsia(FD) and their effects on quality of life(QOL) in firefighters. METHODS: This study examined data collected from 1,217 firefighters. We measured psychological symptoms by Patient Health Questionnaire-9(PHQ-9), Generalized Anxiety Disorder questionnaire(GAD-7), Korean Occupational Stress Scale(KOSS), Ways of Coping checklist(WCCL), Rosenberg's Self-Esteem Scale(RSES) and World Health Organization Quality of Life Scale abbreviated version(WHOQOL-BREF). Chi-square test, independent t-test, Pearson's correlation test, logistic regression analysis, and hierarchical regression analysis were used as statistical analysis methods. RESULTS: For the group with FD, the male participants showed significantly higher frequency(p=0.006) compared to the female participants. The group with FD had higher scores for depressive symptoms(p<.001), anxiety (p<.001), and occupational stress(p<.001), and did lower scores for self-esteem(p=.008), quality of life(p<.001) than those without FD. The FD risk was higher in the following KOSS subcategories: job demand(OR 1.94, 95% CI : 1.29-2.93), lack of reward(OR 2.47, 95% CI : 1.61-3.81), and occupational climate(OR 1.51, 95% CI : 1.01-2.24). In the hierarchical regression analysis, QOL was best predicted by depressive symptoms, self-esteem, and occupational stress. Three predictive variables above accounts for 42.0% variance explained of total variance. CONCLUSIONS: The psychosocial factors showed significant effects on FD, and predictive variables for QOL were identified based on regression analysis. The results suggest that the psychiatric approach should be accompanied with medical approach in future FD assessment.

Sodium picosulfate/magnesium citrate (Picolight Powder), which is used as a bowel preparation for the colon and the rectum, can cause a severe electrolyte imbalance like hyponatremia. When hyponatremia gets severe or occurs rapidly, it can lead to death due to associated complications. We have experienced a case of hyponatremia associated with seizure and loss of consciousness in a 76-year-old woman, who took sodium picosulfate/magnesium citrate as a bowel preparation for colonoscopy. She was taking thiazide and synthroid for the treatment of hypertension and hypothyroidism, respectively, and she had other underlying medical conditions such as a history of seizure and dementia. Following the diagnosis of hyponatremia, we used an intravenous injection of 3% NaCl to normalize the sodium level in her serum, and her associated symptoms soon disappeared.

The pneumonia severity index (PSI) and CURB-65 are widely used tools for the prediction of community-acquired pneumonia (CAP). This study was conducted to evaluate validation of severity scoring system including the PSI and CURB-65 scores of Korean CAP patients. In the prospective CAP cohort (participated in by 14 hospitals in Korea from January 2009 to September 2011), 883 patients aged over 18 yr were studied. The 30-day mortalities of all patients were calculated with their PSI index classes and CURB scores. The overall mortality rate was 4.5% (40/883). The mortality rates per CURB-65 score were as follows: score 0, 2.3% (6/260); score 1, 4.0% (12/300); score 2, 6.0% (13/216); score 3, 5.7% (5/88); score 4, 23.5% (4/17); and score 5, 0% (0/2). Mortality rate with PSI risk class were as follows: I, 2.3% (4/174); II, 2.7% (5/182); III, 2.3% (5/213); IV, 4.5% (11/245); and V, 21.7% (15/69). The subgroup mortality rate of Korean CAP patients varies based on the severity scores and CURB-65 is more valid for the lower scores, and PSI, for the higher scores. Thus, these variations must be considered when using PSI and CURB-65 for CAP in Korean patients.

OBJECTIVE: To determine which mode of ultrasonography (US), among the conventional, spatial compound, and tissue-harmonic methods, exhibits the best performance for the detection of Implanon(R) with respect to generation of posterior acoustic shadowing (PAS). MATERIALS AND METHODS: A total of 21 patients, referred for localization of impalpable Implanon(R), underwent US, using the three modes with default settings (i.e., wide focal zone). Representative transverse images of the rods, according to each mode for all patients, were obtained. The resulting 63 images were reviewed by four observers. The observers provided a confidence score for the presence of PAS, using a five-point scale ranging from 1 (definitely absent) to 5 (definitely present), with scores of 4 or 5 for PAS being considered as detection. The average scores of PAS, obtained from the three different modes for each observer, were compared using one-way repeated measure ANOVA. The detection rates were compared using a weighted least square method. RESULTS: Statistically, the tissue harmonic mode was significantly superior to the other two modes, when comparing the average scores of PAS for all observers (p < 0.00-1). The detection rate was also highest for the tissue harmonic mode (p < 0.001). CONCLUSION: Tissue harmonic mode in uS appears to be the most suitable in detecting subdermal contraceptive implant rods.

BACKGROUND: Various staging systems for thyroid cancer that focus on cancer specific death have been suggested, but this approach had a limitation due to the relatively long clinical course and very low rate of cancer death. This study was performed to evaluate the staging systems and to determine the most predictive staging system for predicting recurrence. METHODS: The patients who underwent first total or near total thyroidectomy due to papillary thyroid cancer (PTC) at Asan Medical Center between January 1995 and December 2001 were the subjects of this study. The commonly used 8 staging systems were applied to these subjects. Disease free survival (DFS) and the relative importance of each staging system were determined by the Kaplan-Meier method, the Cox-proportional hazards model and the proportion of variation in the survival time explained (PVE). RESULTS: A total of 952 patients (M = 117, F = 835) were enrolled and their mean age was 45 years. During a median of 10 years of follow-up, 146 (15.3%) of 952 patients had recurred tumor. The independent prognostic factors were male gender, tumor size, extrathyroidal invasion and cervical lymph node metastasis. Risk stratification according to the American thyroid association (ATA) guideline was the most predictive staging system for recurrence of PTC (PVE 88.6%). The staging systems from EORTC (PVE 79.5%), and MACIS (PVE 68.4%) had significant values for predicting recurrence of PTC. The stage of NTCTCS could not predict recurrence (PVE 4.5%, P = 0.11). CONCLUSION: Risk stratification according to the ATA was most predictive staging system for predicting recurrence of PTC. The MACIS and EORTC staging systems have good value for predicting recurrence of PTC.

PURPOSE: Uncontrolled bleeding is a leading cause of death in multiple-injury patients. It is very difficult to control hemorrhage due to microvascular injury in soft tissue by surgery or vascular intervention. Thus, hemostatic agents such as recombinant activated coagulation factor VII (rFVIIa) have become popular with regard to reducing transfusion volumes and correcting the hemorrhage-associated coagulopathy. METHODS: From March 2007 to January 2010 we used rFVIIa in 15 multiple-injury patients. Transfused packed red blood cell (pRBC) volume was compared before and 6 h after administration of rFVIIa. Complete blood count, prothrombin time and activated partial thromboplastin time were also checked. RESULTS: Mortality rate correlated strongly with initial severity of coagulopathy. Transfused pRBC volumes per hour were reduced significantly after rFVIIa (p=0.01), and coagulopathy was also significantly corrected. Thromboembolic events such as acute myocardial infarction and cerebrovascular attack, a fatal complication of rFVIIa, did not occur. CONCLUSION: The administration of rFVIIa can correct hemorrhage associated coagulopathy and reduce pRBCs transfusion volume. A quick decision regarding the administration of rFVIIa is needed for a more favorable outcome in multiple-injury patients with hemorrhagic shock.

PURPOSE: We performed this study to determine how the emergency trauma team affects the treatment of patients with multiple severe trauma and to discuss the effect and the direction of the emergency trauma team's management. METHODS: We performed a retrospective analysis of 518 patients who visited our emergency department with severe trauma from August 2006 to July 2008. We divided the severe trauma patients into 2 groups : patients before and after trauma team management (Group 1 and Group 2). Then, we compared demographic characteristics, mechanisms of injury, and treatment outcomes (lengths of stay in the ED, admission ratio, and in-hospital mortality) between the 2 groups. In the same way, patients with multiple severe trauma were divided into 2 groups, that are patients before and after trauma team management (Group 3 and Group 4) and analyzed. RESULTS: There was no significant difference, except mean age, between groups 1 and 2. In group 4 patients, compared to group 3 patients, the lengths of stay in the ED were lower (p value < 0.001), and the admission ratio were higher (p value = 0.017), but there was no significant difference in the in-hospital mortality between the groups 3 and 4. CONCLUSION: When patients with multiple severe trauma visit the ED, the emergency trauma team's management can decrease the lengths of stay in the ED and increase the admission ratio, but does not produce a decrease in the in-hospital mortality rate. Further investigations of emergency trauma team management are needed to improve treatment outcomes for patients with multiple severe trauma.

PURPOSE: The mortality and the amputation rates due to vascular trauma remain high despite advanced vascular surgical techniques and supportive management. The clinical features of patients with vascular trauma have not been well studied in the Korean population. The aim of this study was to analyze the clinical characteristics of patients with vascular trauma and to develop a database and guidelines for improving the outcomes of treatment. METHODS: The medical records of 37 patients with traumatic vascular injuries who had visited in an emergency center between January 2002 and December 2006 were retrospectively reviewed and statistically analyzed. RESULTS: The mean age was 37.8 years, and the male-to-female ratio was 5.2 : 1. The mechanism of vascular trauma was penetrating in 18 patients and blunt in 19 patients. Upper extremities were most frequently injured (39.4%). The treatment methods were primary repair in 21 patients, exploratory laparotomies in 7, radiological interventions in 3, resections and graft interpositions of the pseudoaneurysm in 3, observations in 3 and a bypass graft in 1. Four out of the 37 patients died, and three of these who died had injuried abdominal vessels. Twenty-five of the patients recovered completely, four expired, seven had neuropathy in the course of treatement, one had his limb amputated, and one experienced wound necrosis. CONCLUSION: Peripheral vessel injuries are commonly accompanied by nerve, muscle, or tendon injuries. Patients without associated fractures or compartment syndrome had good prognosis. Although the time intervals from hospital arrival to definite treatment were the shortest among patients with blunt abdominal vascular injuries, three expired. Therefore, we offer a 'critical pathway' to improve the outcomes of patients with blunt abdominal vascular injury.
