A 62-year-old woman without vascular risk factors presented with left-sided weakness and numbness.
Magnetic resonance imaging (MRI) brain depicted acute right hemispheric infarcts in the cortical and
subcortical white matter. Initial MR angiography (MRA) showed large thrombus at the right carotid
bifurcation. Valvular atrial fibrillation (vAF) with severe tricuspid regurgitation (TR) was found on
two-dimensional echocardiography. Serial follow-up computed tomography angiography (CTA) or
MRA at 3, 9, and 15 days after anticoagulation alone showed complete resolution of the thrombus
with no neurological deterioration. Our case suggests that prompt institution of anticoagulantion alone
may result in radiologic resolution of the thrombus with improvement in patient’s clinical status.

PURPOSE: The staging of bladder carcinoma is a major determinant of operative management. CT of bladder carcinoma has been widely used to diagnose external extension (pT3b and over), but tumors confined to the bladder wall (from pT1 to pT3a) are poorly delineated. The authors describe CT findings of the superficial bladder carcinoma (below T1, stage A) in thin section CT with air insufflation technique (air insufflation-CT) to facilitate early detection and to aid correct staging of the superficial bladder carcinoma. MATERIALS AND METHODS: The materials consisted of proved 24 cases (1'9 patients, single tumor: 16 patients, multiple tumors :3 patients) of stage A bladder carcinomas. Air insufflation-CT was performed by the infusion of approximately 200 mL of air into the bladder via a Foley catheter. After the routine pelvic CT, bladder tumors were re-scanned with 1.5 to 5 mm thickness and intervals. RESULTS: The superficial bladder carcinomas were detected as nodular(5 cases, 20.8%), papillary(15 cases, 62.5%), pyramidal(2 cases, 8.3%), and domed(2 cases, 8.3%) forms on air insufflation CT. These tumors were classified into three types according to the size of the tumoral neck:type I(pedundulated polypold tumor:4 cases, 16.6%), type II(polypid tumor with short neck :13 cases, 54.2%), and type Ill(sessile tumor :7 cases, 29. 2%). The mean size(tumoral width x height x base o, neck/stalk) of the tumors was 22 x 20 x 16mm. The average tumoral sizes according to each type of the superficial tumors were type 1:22 x 25 x 6mm, type 11:23 x 22 x 18mm, and type III :18 x 15 x 18mm. The mean width of the type I--II tumoral necks was 15mm. The mean length of the type I tumoral neck(pedicle) was 2.5mm. Papillary fronds of the tumors were seen in 10 cases(41.7%) of 24 superficial tumors. Outer margin of the involved bladder wall was smooth in all cases. CONCLUSION: Thin-sectin CT with air insufflation technique for bladder carcinoma was useful in tumoral demonstration, and characteristics of the superficial bladder carcinomas were small polypold tumors had a short neck mostly and smooth outer wall of the involved bladder wall.

OBJECTIVES: The purpose of this study was to compare psychological test profiles of psychiatric outpatients with high and low depression/suicide ideation and to identify predictor variables for depression/suicide ideation. METHODS: Component scores of the Personality Assessment Inventory (PAI) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2) were compared using t-tests. Discriminant analysis was conducted for predictor variables of depression/suicide ideation. RESULTS: Regarding PAI profiles, somatic complaints (SOM), anxiety (ANX), anxiety-related disorder (ARD), depression (DEP), paranoia (PAR), borderline features (BOR), antisocial features (ANT), mania (MAN) drug problems (DRG) scores were significantly elevated in high depression and high suicide ideation groups. Concerning MMPI-2 profiles, the scores of hypochondriasis (Hs), depression (D), hysteria (Hy), psychopathic deviate (Pd), paranoia (Pa), psychasthenia (Pt), schizophrenia (Sc), social introversion (Si) were significantly elevated in these same groups. The PAI and MMPI-2 profile shapes were remarkably similar between high depression and high suicide ideation groups. Therefore, in terms of psychological profile, depression and suicidal ideation seemed to reflect the same construct. However, in discriminant analysis, significant predictors for depression were found to be Pt and D Sc from MMPI-2, while those for suicide ideation were found to be Pa and Sc, suggest subtle differences. CONCLUSION: The superficial characteristics of depression and suicide ideation groups reflected by the psychological test profiles seemed similar, but the determining factors may differ. Thus, the psychological interventions for these two groups may have to follow different routes considering these subtle differences.

PURPOSE: Radiocontrast media are widely used in medical imaging to improve diagnostic accuracy. However, studies on the adverse reactions of radiocontrast media in children are limited. We aimed to describe the characteristics of adverse reactions to radiocontrast media among children who had a computed tomography scan or magnetic resonance imaging in a tertiary university hospital. METHODS: We retrospectively collected data on adverse reactions to radiocontrast media by the reporting system of a tertiary university hospital. We selected data from children under the age of 19 from July 2011 to December 2017 and analyzed their characteristics. We focused mainly on the characteristics of the index case which is defined by the first adverse event of each subject. RESULTS: During the period, a total of 88,050 radiocontrast media-enhanced imaging studies were performed and 184 cases of adverse reactions were reported. A total of 71 were identified as index cases. Forty-nine (69.0%) were male and the mean age was 12.7±3.2 years. The incidence of radiocontrast media-related adverse reactions was 0.09% and severe reactions were 0.002%. The most common clinical feature was skin manifestations (54.9%), followed by gastrointestinal symptoms (40.8%) and neuropsychiatric symptoms (7.4%). CONCLUSION: Adverse reactions to radiocontrast media rarely occur in children and the incidence of severe reactions is low. Most reactions are mild and are related to the skin and gastrointestinal system. This report would provide good evidence for establishing a management strategy in children scheduled for imaging studies using radiocontrast media.

OBJECTIVE: To evaluate the current status of managing adverse reactions to iodinated contrast media (ICM) for computed tomography in referral hospitals in South Korea compared with hospitals in other countries. MATERIALS AND METHODS: This survey investigation involved 59 Korean and 15 overseas hospitals using guideline-based questionnaires consisting of 24 items in 7 main categories related to managing adverse reactions to ICM. RESULTS: Informed written consent with risk factor evaluation was appropriately performed in most of the Korean hospitals. There was considerable variability in assessing renal function across the hospitals; serum creatinine level was used as a reference in 76.4% of Korean hospitals. The Korean hospitals preferred a more stringent approach to determining normal renal function (p = 0.01), withholding metformin (p = 0.01), and fasting before ICM exposure (p < 0.001) compared with overseas hospitals. All the Korean hospitals had an emergency protocol and in-hospital system for adverse reactions to ICM. The Korean (87.7%) and overseas hospitals (100%) were similarly equipped with epinephrine (p = 0.332), but only 38.6% of Korean hospitals were equipped with a bronchodilator (p = 0.004). For patients with a previous hypersensitivity reaction to ICM, 62.3% of Korean hospitals pre-medicated with anti-histamine and corticosteroid according to the severity of the previous reaction, and changed the culprit ICM in 52.8%, while skin test was performed in 17%. CONCLUSION: In general, Korean referral hospitals were well-prepared regarding informed consent, protocol, and an in-hospital system for managing adverse reactions to ICM. Nevertheless, there was considerable variability in details and management, thus requiring standardization by reflecting current guidelines.

Undifferentiated (embryonal) sarcoma of the liver is a rare and highly malignant hepatic neoplasm of a mesenchymal origin. This tumor almost exclusively affects pediatric patients, and the prognosis is poor. Although there has been controversy as to the most appropriate treatment, the previous studies have reported that long term survival is possible after complete surgical resection with or without perioperative chemotherapy. We report here on a case of undifferentiated (embryonal) sarcoma of the liver, which showed cystic formation, in a 37-year-old woman with no prior history of any hepatitis or liver cirrhosis. She was admitted with right abdominal pain. The physical examination findings were unremarkable except for tenderness in the right abdomen.

It is common to use semiclosed circle system for general anesthesia because of economy, easy controllability of humidity and temperature, less contamination of operating room with anesthetic gas etc, but in case of malfunction of unidirectional valve, inappropriate absorption of carbon dioxide,leakage or obstruction of circle system the patient may become fatal. During general anesthesia with newly purchased anesthesia machine(Ohmeda Modulus II plus) we experienced three cases of hypercarbia because of malfunction of expiratory valve which could not be easily found due to overlying PEEP valve.

BACKGROUND: Functional dyspepsia (FD) is a commonly encountered disturbance of gut function and has been shown to be associated with psychological disturbance such as depression and anxiety. Of particular importance to clinicians are the relationship between anger, alexithymia, and depression. In this study, we investigated anger, alexithymia, and depression in patients with functional dyspepsia. METHODS: Thirty patients who visited Wonkwang University Hospital from January 2001 to June 2001, were diagnosed with functional dyspepsia by a gastroenterologist and compared with 37 healthy control group. Medical investigation of FD including gastrofiberscopy, esophageal manometry, and ambulatory 24-hours intraesophageal reflux test were negative. All subjects were evaluated for depression, anxiety, anger and anger expression, and alexithymia. The measures included Beck Depression Inventory (BDI), Spielberger State-Trait Anxiety Inventory (STAI), Spielberger State-Trait Anger Expression Scale (STAXI), and Toronto Alexithymia Scale (TAS). RESULTS: The FD patients reported significantly more symptoms of depression, more difficulty describing feeling to others in TAS, less anger-in and anger-out expression in STAXI than the control subjects. Depressive symptoms in FD were positively correlated with state anxiety, trait anxiety, alexithymia, state anger, trait anger, and anger-in expression. In multiple regression model, state anger and trait anxiety together accounted for 69.1% of the depression in FD. CONCLUSION: The FD patients reported more depressive symptoms, and the depressive symptoms were related to anxiety, anger and anger-in, and alexithymia. These finding lend support that FD is a syndrome in which biopsychosocial process and affect dysregulation may play a role in features of FD.

PURPOSE: The purpose of this study was to evaluate the diagnostic accuracy of 3.0-T breast MRI for detecting additional breast cancer soon after the initial diagnosis of breast cancer. MATERIALS AND METHODS: From March to June 2009, 101 patients recently diagnosed breast cancer underwent breast MRI and surgery. Parameters analyzed on MRI were total extent of tumor, suspicious findings of multifocal, multicentric, or contralateral cancer. The diagnosis of MRI-detected cancer was confirmed by means of biopsy or surgical specimen evaluation after the localization. RESULTS: MRI showed 37 additional suspicious findings in 34 patients. Twenty nine findings were true-positive (29/37, 78.4%), including 16 cases of multifocality, 11 cases of multicentricity and 2 cases of contralateral cancer. Among these cancers, 13 (44.8%) were ductal carcinoma in situ (DCIS) and 16 (55.1%) were infiltrating cancer. Eight findings were false-positive (8/37, 21.6%) including 6 cases of benign disease and 2 cases of high-risk lesions. CONCLUSION: In women with recently diagnosed breast cancer, 3.0-T MR imaging showed additional suspicious findings in 33.7%. The sensitivity and specificity for detecting additional breast cancer was 100% and 89.3%, respectively.
