Balloon dilatation of congenital stenotic lesion of the pulmonic valve has been used. Repeated balloon dilatation of restenosed lesion after previous balloon dilatation for the pulmonic stenosis is needed in some case. We treated a case of pulmonic restenosis with using three balloon catheters in a boy. The most critical problems related the valvuloplasty are severe systemic hypotension and bradycardia due to stasis of blood flow. The use of three balloon catheters instead of single or double balloons for the pulmonic stenosis could be a alternative interventional method to preserve the preexistent forward blood flow during inflation and to minimize vascular injury in children with large valve annulus.

OBJECTIVE: The aim of this study was to develop a culturally sensitive instrument that addressed how individuals express and experience depression to detect this disorder in Koreans. We also assessed the validity, reliability, and diagnostic utility of this scale (Lee and Rhee Depression Scale; LRDS). METHODS: The sample consisted of 3,697 normal adults selected from 12 administrative districts (Do) and 448 Korean patients diagnosed with depression using the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I). Reliability was calculated using Cronbach's alpha. Construct validity, discriminant validity, and concurrent validity were also measured. Receiver-operator-characteristic (ROC) analysis was employed to evaluate diagnostic efficiency. RESULTS: The LRDS was found to be a reliable instrument (Cronbach's alpha=0.95) consisting of six factors: negative thinking about the future, negative thinking about the self, worry and agitation, depressed mood, somatization, and loss of volition. Comparison of LRDS scores discriminated the group of patients with depression from the normal individuals in the control group. The measure showed good concurrent validity in that scores were significantly and strongly correlated with scores on established scales such as the Beck Depression Inventory (BDI), the Hamilton Depression Rating Scale (HAM-D), and the D scale of the Minnesota Multiphasic Personality Inventory-second edition (MMPI-2). Diagnostic efficiency was 77.7%, and the cut-off scores were 65 for males and 70 for females. CONCLUSION: To our knowledge, this is the first study to develop a depression-screening scale on the basis of Korean patients' complaints about the disorder. As a culturally sensitive tool, the LRDS will be useful in clinical and research settings in Korea.

Primary spontaneous cervical spondylolysis is a rare anomaly, and is often diagnosed as a traumatic lesion such as a fracture or a locked facet; alternatively, it may be overlooked. A literature review revealed one report that addresses the usefulness of three-dimensional reconstruction computed tomography (CT) imaging in the diagnosis of cervical spondylolysis. We have experienced two cases of subaxial cervical spondylolysis. One patient was transferred to our institute due to trauma, and the other patient was referred from a local hospital without trauma history. In this second patient symptoms occurred spontaneously and showed insidious progression. Both cases typically involved the right side of the C6 vertebra. The author utilized three-dimensional (3-D) reconstruction computed tomography (CT) for diagnosis and evaluation. Among those issued in Korea, this is the first report of primary subaxial cervical spondylolysis evaluated using 3-D CT.

OBJECTIVE: Persistent trigeminal artery variant (PTAV) is an anastomosis between the internal carotid artery (ICA) and the cerebellar artery without any interposing basilar artery segment. We discuss its probable embryological origin and emphasize clinical implications. METHODS: Retrospectively 1250 conventional cerebral angiograms and 2947 cranial magnetic resonance angiographies (MRAs) were evaluated for the patients with PTAV. RESULTS: Five patients (four men and one woman, 23 to 76 years of age, median age 65 years) had a PTAV. Three patients who underwent MRA had a PTAV (3/2947=0.1%). Four of the patients who underwent cerebral angiography had a PTAV (4/1250=0.32%). Two of 143 patients who underwent both conventional angiography and cranial MRA showed PTAV. The PTAV was an incidental finding in all five patients. The PTAV originated from the cavernous segment of the left ICA in four patients and from the cavernous segment of the right ICA in one patient. The terminal branch of the PTAV was the anterior inferior cerebellar artery (AICA) and superior cerebellar artery (SCA) in two patients and the AICA only in the other three patients. CONCLUSION: Neurosurgeons should be aware of possible presence of PTAV. Manipulation of this vessel during a surgical approach to the parasellar region and percutaneous gasserian ganglion procedure may result in hemorrhage or ischemia.

PURPOSE: The purpose of this study was to compare the perception of learning outcomes between faculty and students in medical schools. METHODS: A total of 1,766 medical students and 436 faculty members participated in the survey. They responded to the perception of four learning outcomes: medical knowledge and problem solving, clinical skills, medical ethics, and clinical communication. The participants responded to the education and achievement levels of the learning outcomes. RESULTS: In all four learning outcomes, the student's perception of education level differed by educational system, and the students in mixed systems had the highest scores. Students differed significantly in achievement level of medical ethics between genders, wherein male students perceived their achievement level to be higher than females. Students perceived their achievement level to be lower than the education level. The students' clinical skills were the highest in the education and achievement levels. The faculty perceived the education level to be higher than the student's achievement level. In particular, the faculty's perception of education level of medical knowledge and problem solving was the highest, whereas the students' achievement level of it was lower. The faculty assessed the education level to be higher than students. The students showed higher perception of achievement level than faculty. CONCLUSION: There were perceptual differences in learning outcomes between students and faculty. The results of this study are expected to be used to design outcome-based learning methods.

The facial flatness was studied by the metric method which involves six measurements of breadth and projection of the midfacial skeleton, the calculation of three indices from the measurements. The indices of the modern Korean adult crania, Korea & Chosun Dynasty crania, the Iron Age Korean crania, and the late Neolithic Korean crania were investigated. The indices were compared to those of other published data on the Korean crania and those of neighboring asian races as well. All indices for facial flatness of Korea & Chosun Dynasty were similar to modern Korean. However, zygomaxillary index was different between modern and late Neolithic crania. The difference of zygomaxillary index was prominent in males than females. The difference of facial flatness between modern and ancient seems to be mainly due to zygomatic breadth. The frontal indices of modern Korean and Korea & Chosun Dynasty crania were relatively low and the simotic indices were relatively high among neighboring asian races. The zygomaxillary index is intermediate. Clustering analysis represented that the flatnesses of the modern Korean crania and Korea & Chosun Dynasty crania were closely related to those of the northern Chinese, modern Japanese, however, somewhat different from that of ancient Korean, Mongol, Siberian etc.

Carbamazepine-induced liver injury is less common, but the consequences of the side effects can be very serious leading to death or a need for liver transplantation. We report a case of a 60-year-old female transverse myelitis patient with fulminant hepatic failure and Stevens-Johnson syndrome induced by carbamazepine who successfully underwent deceased donor liver transplantation. The patient, a 60-year-old female, was admitted to our service due to acute liver insufficiency and a drowsy mental state attributable to carbamazepine. She had been treated with carbamazepine to control transverse myelitis. Fifty days after the use of carbamazepine, she developed jaundice, erythematous papules and bullae, and decreased consciousness. The diagnosis of Stevens-Johnson syndrome was considered. She underwent deceased donor liver transplantation. She was discharged with normal graft functions 5 months after transplantation. Thus, liver transplantation can be a feasible therapy for patients with carbamazepine-induced hepatic failure associated with Stevens-Johnson syndrome.

BACKGROUND AND OBJECTIVES: Atrial fibrillation (AF) has long been recognized as a random phenomenon. Recent studies, however, suggest that activation sequence during atrial fibrillation is not entirely disorganized and organized activations as the transitional rhythm exists in the process of conversion from atrial fibrillation to atrial flutter. The purpose of this study is to characterize the process and significance of transitional rhythm during conversion of atrial fibrillation to atrial flutter. MATERIALS AND METHODS: In 9 patients with paroxysmal atrial fibrillation, 13 episodes that atrial fibrillation spontaneously converted to atrial flutter during electrophysiological study were analyzed. To map the right atrium (RA), 10 bipolar Halo catheter was positioned in the lateral free wall of the RA and multielectrode catheters were positioned in the coronary sinus, high RA, and His bundle area, respectively. Calculation of cycle length (CL) was performed with digital caliper during atrial fibrillation and atrial flutter. Direction of activation sequences was compared between transitional rhythm and following atrial flutter. RESULTS: During conversion of atrial fibrillation to atrial flutter, characteristic findings were observed as follows. 1) There was a gradual increase in atrial fibrillation cycle length before transitional rhythm. 2) A pause appeared in atrial fibrillation immediately prior to transitional rhythm, and between transitional rhythm and following atrial flutter. 3) Direction of activation sequences of the transitional rhythm to atrial flutter was concordant in 9 episodes and discordant in 4 episodes. 4) Spontaneous termination of atrial flutter (n=3) was also preceded by organized rhythm showing different sequence of activations from those of atrial flutter. CONCLUSION: A stereotypical pattern of activation sequence exists in the process of conversion of atrial fibrillation to atrial flutter. The occurrence of transitional rhythm influences the activation sequence of atrial flutter. Spontaneous termination of atrial flutter also preceded by transiently changing pattern of activation.

BACKGROUND AND PURPOSE: Left ventricular hypertrophy (LVH) is a well known cardiovascular risk factor, independent of hypertension, even in the absence of epicardial coronary artery disease. Possible mechanisms have been proposed, including increased LV mass, reduced coronary flow reserve (CFR) and diastolic filling abnormalities. However, the relations among LV hypertrophy, diastolic function, hypertension and coronary flow reserve (CFR) in patients with chest pain and normal coronary angiograms have not been well defined. SUBJECTS AND METHOD: Twenty-six patients with chest pain and normal coronary angiograms were included. LV mass, isovolumic relaxation time (IVRT), deceleration time (DT) and E/A ratio were assessed by 2-D echo-cardiography. Coronary blood flow velocity before and after intracoronary adenosine were measured using intracoronary Doppler wire (FIoWire). CFR was defined as ratio of peak flow velocity after adenosine to baseline flow velocity. Subjects were devided into 4 groups according to presence of LVH and hypertension and the parameters were compared among groups. RESULTS: FR was lower (p<0.01) in the groups with either hypertension or LVH or both than in the groups without them. The decrement in CFR was not linearly related to the degree of LVH (r=0.31, p=0.135). Although there were modest increment in IVRT and DT and decrement in E/A ratio in the groups with hypertension or LVH or both, there was no statistical significance. CONCLUSION: These findings suggest that the underlying mechanism of impaired CFR in patients with LVH or hypertension may be the consequence of primary coronary microvascular lesion rather than the process of left ventricular hypertrophy.
