Reliability and Validity of the Korean Version of the General-Food Craving Questionnaire-Trait for Children

OBJECTIVE: The General-Food Craving Questionnaire-Trait (G-FCQ-T) is a validated, assessment scale for food craving. The aim of this study was to measure its reliability and validity for Korean children. METHODS: A total of 172 children (94 boys and 78 girls) were selected to fill out a set of questionnaires, including the G-FCQ-T, the Children's version of the Dutch Eating Behavior Questionnaire (DEBQ-C), and the Three-Factor Eating Questionnaire (TFEQ) in the Korean language. RESULTS: The internal consistency (Cronbach's alpha=0.933) and test-retest reliability (r=0.653) were satisfactory. The G-FCQ-T showed a significantly positive correlation with the DEBQ-C (r=0.560) and the TFEQ (r=0.397). The optimum cutoff score of the G-FCQ-T set by Receiver Operating Characteristics analysis was 51, with sensitivity and specificity of 0.833 and 0.825, respectively, for children. CONCLUSION: The G-FCQ-T showed good reliability and validity for assessing food craving for children and could become a practial instrument in clinical and research settings.

The Effect of Behavior Inhibition System on Smart-Phone Addiction : The Mediation Roll of Depression / 신경정신의학

OBJECTIVES: This study was conducted to examine the mediating effect of depression on the relationship between behavior inhibition system (BIS) and smart-phone addiction (SA) in Korea. METHODS: An online survey was conducted including 5003 adult participants. Except for people without a smartphone, participants consisted of 2573 men and 2281 women, including a 20s group, 1611, 30s group, 2133, and 40s group, 1110. For evaluation of psychiatric symptoms and personal characteristics, participants were asked to complete self-reports, including BIS scale, depression scale of SCL-90-R (Dep), and SA scale. RESULTS: The BIS predicted both variance of depression and SA (BIS→Dep : β=0.374, p<0.001 ; BIS→SA : β=0.268, p<0.001), and depression predicted SA (β=0.386, p<0.001). The result of hierarchial regression analysis showed that depression mediated the relationship between behavior inhibition system and SA. Thus the effects between behavior inhibition system and smartphone decreased (β=0.268→0.144). CONCLUSION: Depression mediates the influence of behavior inhibition system on SA. This result indicates that biological traits and negative emotions, such as depression, have an important influence on behavioral addiction.

Pulsed Wave and Color Doppler US Findings of Transjugular Intrahepatic Portosystemic Shunts (TIPS)

The transjugular intrahepatic portosystemic shunt (TIPS) is an effective and relatively safe and widely accepted treatment for complications arising from portal hypertension. Shunt or hepatic vein stenosis and shunt occlusion are common short- and medium-term complications arising from the procedure, though if detected early, these conditions may be treated before the recurrence of gastrointestinal bleeding or ascites. Doppler US is a relatively inexpensive, accurate, and noninvasive method for the evaluation of shunt status.

Doppler US Findings of Vascular Complication after Liver Transplantation

Vascular complications after liver transplantation may involve the hepatic artery, and hepatic and portal veins. Arterial complications are common and significant vascular complications include thrombosis or stenosis, as well as pseudoaneurysms. Venous complications include thrombisis or stenosis of the inferior vena cana, or hepatic or portal vein. Since recent evidence has shown that emergent revascularization leads to improved graft salvage and patient survival with a relatively low rate of late biliary complications, accurate and pronpt di-agnosis of hepatic arterial complications is important. Doppler US is a relatively inexpensive, accurate, and non-invasive method of diagnosing the vascular complications which may arise from liver transplantation.

Intrahepatic Cholesterol Stones: Report of Two Cases

Hepatolithiasis is rare in western countries, but is fairly common in East Asia, including Japan, China, and Taiwan. Calcium bilirubinate stones account for the majority of intrahepatic calculi, while intrahepatic cholesterol stones are very rare, the incidence being 0.37% of all gallstones. However, several investigators have recently reported an increased incidences of cholesterol gallstones in hepatolithiasis cases and have discussed the differing mechanisms for their formation in the intrahepatic biliary tree of patients with calcium bilirubinate stones and cholesterol stones. We report two cases of intrahepatic cholesterol stone, with emphasis on the radiologic findings, and review the literature.

Mass - Forming Chronic Pancreatitis: CT and ERCP Features

PURPOSE: To describe the CT and ERCP findings of mass-forming chronic pancreatitis. MATERIALS AND METHODS: CT and ERCP features were assessed in 13 patients suffering from mass-forming chronic pancreatitis. Diagnosis was on the basis of surgery (n=5), percutaneous needle biopsy (n=3), and clinical follow-up (n=5). Contrast-enhanced CT was available for all patients: five underwent dynamic study and ERCP was performed in 12. On CT and ERCP, both groups were evaluated with regard to the presence and degree of pancreatic ductal dilatation (greater or less than 50 % of total gland width), double duct sign, enhancement pattern, pancreatic parenchymal calcification (site and distribution pattern), mass identification, the direction of infiltration, pancreatic parenchymal atrophy, configuration at the site of obstruction in the pancreatic and common bile duct, lymphadenopathy, vascular encasement, and vascular engorgement or increased collateral vessels in the peripancreatic space. RESULTS: Seven of 13 patients had suffered chronic alcoholism. Serum CA19-9 levels were normal in all patients except one. Common CT and ERCP findings of mass-forming chronic pancreatitis included pancreatic duct dilatation (92.3%), double duct sign(69.2%), inhomogeneous enhancement of the mass (69.2%), and the presence of calcification (61.5%). Patterns of pancreatic duct dilation were irregular in five patients (38.4%) and smooth in three (23.1 %).In all patients, duct dilatation was less than 50 % of total gland width. Enhancement patterns of the pancreatic mass were inhomogeneous (69.2%), a nonenhancing low attenuation mass (15.3%), and homogeneous enhancement (15.3 %). Configuration at the site of obstruction in the pancreatic duct was abrupt termination in two patients (15.4 %) and smooth termination in two (15.4 %). The common bile duct teminated abruptly in three patients (23.1%), and in four (30.8 %) smooth narrowing was abserved. CONCLUSION: Common findings of mass-forming chronic pancreatitis were duct dilatation of less than 50 % of total gland width, double duct sign, inhomogeneous enhancement of the mass, and the presence of calcification. These were combined with observation of clinical findings such as chronic alcoholism and CA19-9 levels, which are useful indicators for differentiating mass-forming chronic pancreatitis from pancreatic cancer.

Zollinger-Ellison Syndrome: A Case Report

Zollinger-Ellison syndrome (ZES) involves hypergastinemia produced by a gastrin-secreting tumor. Not only can it cause an ulcer but may also behave as a malignant lesion, metastasizing to the liver or other organs. The development of potent antisecretory agents for controlling acid secretion as well as techniques for localizing these islet cell tumors, has led to greatly improved survival rates. We describe a case of Zollinger-Ellison syndrome, emphasising the radiologic findings, and including a review of the literature.

Radionuclide Cisternographic Findings in Patients with Spontaneous Intracranial Hypotension / 대한핵의학회잡지

PURPOSE: Radionuclide cisternography may be helpful in understanding pathophysiology of postural headache and low CSF pressure in patients with spontaneous intracranial hypotension. The purpose of this study was to characterize radionuclide cisternographic findings of spontaneous intracranial hypotension. MATERIALS AND METHODS: The study population consists of 15 patients with spontaneous intracranial hypotension. Diagnosis was based on their clinical symptoms and results of lumbar puncture. All patients underwent radionuclide cisternography following injection of 111 to 222 MBq of Tc-99m DTPA into the lumbar subarachnoid space. Sequential images were obtained between 1/2 hour and 24 hour after the injection of Tc-99m DTPA. Radioactivity of the bladder, soft tissue uptake, migration of radionuclide in the subarachnoid space, and extradural leakage of radionuclide were evaluated according to the scan time. RESULTS: Radionuclide cisternogram showed delayed migration of radionuclide into the cerebral convexity (14/15), increased soft tissue uptake (11/15), and early visualization of bladder activity at 30 min (6/10) and 2 hr (13/13). Cisternography also demonstrated leakage site of CSF in 4 cases and 2 of these were depicted at 30 min. Epidural blood patch was done in 11 patients and headache was improved in all cases. CONCLUSION: The characterstic findings of spontaneous intracranial hypotension were delayed migration of radionuclide and early visualization of the soft tissue and bladder activity. These scintigraphic findings suggest that CSF leakage rather than increased CSF absorption or decreased production may be the main pathophysiology of spontaneous intracranial hypotension. Early and multiple imaging including the bladder and soft tissue is required to observe the entire dynamics of radionuclide migration.

Imaging Findings of Tumor Involving Hard Palate

OBJECTIVE: The purpose of this study is to evalute characteristic CT and/or MR imaging findings of varioushard palatal tumors. SUBJECTS AND METHODS: Fifteen patients(M:12, F:3, mean age:54 years) with a hard palataltumor were included in this study. In all cases, diagnostic images were obtained(CT only : 10, MRI only: 2, CT andMRI:3), and in all patients the condition was pathologically proven. To determine tumor location and bony change,each imaging finding was retrospectively reviewed. RESULT: Among the 15 patients, tumor of a minor salivary glandwas most common(n=9), followed by squamous cell carcinoma(n=4). In nine cases, the tomor was located at thepalatal shelves, and in six, at the alveolar process-palatal angle. The pattern of bony change was destructive inseven cases, erosive in six, and infiltrative in two. In all cases, adenoid cystic carcinoma and meta statictumor, including squamous cell carcinoma, involved the palatal shelves and presented as destructive orinfiltrative bony change. pleomorphic adenoma and mucoepidermoid carcinoma arose at the alveolar process-palatalangle and posterolateral portion of the hard palate and in all cases presented as erosive bony change. CONCLUSION: The characteristic features of location and bony change are useful for the evaluation and differentiation ofhard palatal tumors.
