Methods: Three hundred and sixty-nine students in art high school completed a battery of measures, including the Korean version of the KMPAI, State-Trait Anxiety Inventory (STAI), Liebowitz Social Anxiety Scale (LSAS), Center for Epidemiologic Studies-Depression Scale (CES-D), and Frost Multidimensional Perfectionism Scale-Korean version (FMPS-K). The construct validity of the Korean version of KMPAI was examined by performing explorative factor analysis. The reliability was assessed by the internal consistency using Cronbach’s alpha. Results: Explorative factor analysis for the construct validity showed that the Korean version of KMPAI was composed of seven factors (factor 1: Worry/dread and Negative cognitions; factor 2: Proximal somatic anxiety and Worry about performance; factor 3: Depression/hopelessness; factor 4: Parental empathy–Memory–Controllability; factor 5: Generational transmission of anxiety;factor 6: Trust; factor 7: Rumination), explaining 61% of the total variance. The T Concurrent validity with the other scales (STAI, LASA, CES-D, and FMPS-K) was statistically significant. The Cronbach’s alpha value for the internal consistency of the Korean version of KMPAI was excellent (r=0.961). Conclusion The Korean version of the KMPAI is a reliable and valid instrument for measuring music performance anxiety in Korea.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is an uncomfortable procedure that requires adequate sedation for its successful conduction. We investigated the efficacy and safety of the combined use of intravenous midazolam and propofol for sedation during ERCP. METHODS: A retrospective review of patient records from a single tertiary care hospital was performed. Ninety-four patients undergoing ERCP received one of the two medication regimens, which was administered by a nurse under the supervision of a gastroenterologist. Patients in the midazolam (M) group (n=44) received only intravenous midazolam, which was titrated to achieve deep sedation. Patients in the midazolam pulse propofol (MP) group (n=50) initially received an intravenous combination of midazolam and propofol, and then propofol was titrated to achieve deep sedation. RESULTS: The time to the initial sedation was shorter in the MP group than in the M group (1.13 minutes vs. 1.84 minutes, respectively; p<0.001). The recovery time was faster in the MP group than in the M group (p=0.031). There were no significant differences between the two groups with respect to frequency of adverse events, pain experienced by the patient, patient discomfort, degree of amnesia, and gag reflex. Patient cooperation, rated by the endoscopist as excellent, was greater in the MP group than in the M group (p=0.046). CONCLUSIONS: The combined use of intravenous midazolam and propofol for sedation during ERCP is more effective than midazolam alone. There is no difference in the safety of the procedure.

PURPOSE: This study aimed to evaluate the status of renal function and the presence of urinary abnormalities in early adult patients with Turner syndrome (TS). METHODS: Sixty-three girls with TS, who are attending pediatric endocrine clinics in Busan Paik Hosp., were studied. Urine and blood chemistry tests were performed in every visiting times. Renal ultrasonography was performed in all patients at the initial diagnosis, and intravenous pyelography, DMSA renal scan and renal CT were also performed, if necessary. RESULTS: Of the 63 patients, the karyotype showed 45,X in 32 (50.8%) , mosaicism in 22 (34.9%) and structural aberration in 9 (14.3%). The renal function at the latest visit was shown as normal in all patients. Nephrotic syndrome had developed in one patient. Hematuria was observed in seven patients. Renal anomalies were observed in 20 of the 63 TS (31.7%). Of the 32 TS patients with 45,X karyotype, 13 (40.6%) had renal anomalies, while these were found in 7 (22.6%) of 31 TS patients with mosaicism/structural aberration. But there was no significant statistical difference between two karyotype groups. CONCLUSION: Based on this study, most of the patients with TS do not have any significant problems related to renal function until early adulthood, regardless of renal malformation or hematuria.

Kasabach-Merritt phenomenon does not occur with common hemangioma, rather it is associated with the more aggressive Kaposiform hemangioendothelioma and rarely with other vascular neoplasm. We report the case of an adult who was diagnosed as Kaposiform hemangioendothelioma complicated by Kasabach-Memtt phenomenon. This is the first report in Korea of an adult with Kasabach-Merritt phenomenon who has osteolytic changes of femur, pelvic bone, and lumbar spine.

OBJECTIVES: The combination therapy with peginterferon and ribavirin has been used to treat chronic hepatitis C for several years in Korea but there is a few report about the results of the treatment. We evaluated safety and efficacy of the combination therapy with Peg-interferon and ribavirin and analyzed factors that may affect treatment. METHODS: Total 72 untreated chronic hepatitis C patients were administered pegylated interferon alfa-2a (180microg/week) or alfa-2b (1.5microg/kg/week) and ribavirin (800 mg/day in genotype 2, 1000-1200 mg/day in genotype 1). Duration of the treatment was 24 weeks in genotype 2 and 48 weeks in genotype 1. Response of the treatment was evaluated by rapid virologic response (RVR), early virologic response (EVR), end treatment virologic response (ETR), sustained virologic response (SVR) and adverse event. RESULTS: The RVR, EVR, ETR, SVR were 61.8%, 82.5%, 88.9% and 80.5% retrospectively. The SVR of genotype 1 was 63.4% and non-genotype 1 was 96.7%. Genotype (Odds ratio: 14.92) was an independent predictor of the SVR. Leukocytopenia, flu-like symptoms, itching, rash and anemia were common adverse events of the combination therapy and if then we reduced dose and there was one case of cessation. CONCLUSIONS: The combination therapy with Peg-interferon and ribavirin shows efficacy to the Korean patients with chronic hepatitis C as an initial treatment. Genotypes 2 and 3 were more likely to have a sustained virologic response.

Plasma cell granuloma is a tumor-like disease characterized by non-neoplastic polyclonal proliferation of plasma cells and other mononuclear cells. This disease occurs most frequently in the lung and upper respiratory tract, while the involvement of the central nervous system is very rare. A 44-year-old female patient presented with nausea and progressive visual disturbance. Brain magnetic resonance imaging (MRI) revealed the mass along the right tentorium with low signal intensity in the T2 weighted image (T2WI) and fluid-attenuated inversion recovery (FLAIR) sequence, and an isosignal intensity in T1 weighted image (T1WI), the latter of which was enhanced after administration of gadolinium-diethylenetriamine penta-acetic acid (Gd-DTPA). The thickest portion of the tentorium was partially excised via the combined suboccipital and infratentorial approach. The histopathological examination indicated a diagnosis of plasma cell granuloma. Postoperative steroid therapy was administered for remnant tumor control. Although a follow up MRI scan taken 20 months after the operation showed a slight decrease in tumor size, the lesion had extended to the falx and left frontal convexity along with parenchymal edema at 32 months after the operation and the clinical status was aggravated. The mass was removed from the left frontal convexity. Radiation therapy was given, together with steroid administration.

Aneurysmal bone cyst (ABC) is benign vascular lesion destructing the cortical bone by the expansion of the vascular channel in the diploic space that usually involve long bone and spine. Orbital ABC is rare and the clinical symptoms deteriorate rapidly after initial slow-progression period for a few months. A 12-year-old female patient visited ophthalmologist due to proptosis and upward gaze limitation of the right eye, and orbital mass was noted in the upper part of right eye on orbital MRI. Five months later, exophthalmos was worsened rapidly with other features of ophthalmoplegia. Orbital mass was enlarged on MRI with intracranial extension. Surgery was done through frontal craniotomy and intracranial portion of the tumor was removed. Destructed orbital roof and mass in the orbit was also removed, and surrounding bone which was suspected to have lesion was resected as much as possible. Histopathological diagnosis was aneurysmal bone cyst. Postoperative course was satisfactory and the patient's eye symptoms improved. Authors report a rare case of orbital ABC with review of the literature. Exact diagnosis by imaging studies is important and it is recommended to perform surgical resection before rapid-progressing period and to resect the mass completely to prevent recurrence.

Central neurocytoma is a rare, well-differentiated neuronal tumor and is usually located in the lateral or third ventricle of young adults. Its overall prognosis is excellent with a low proliferative index. The majority of previously reported malignant variants rarely did recurred after tumor removal and regarded as benign tumor despite of histopathological malignant feature. Nevertheless, we experienced a case of malignant variant of the central neurocytoma with high proliferative index(Ki-67 labeling index >30%), which showed recurrence immediately after surgery and died within 3 months POD. Here, we describe the case with a review of the literatures.

Erlotinib (Tarceva(R)) is a new anti-cancer agent which acts by inhibiting epidermal growth factor receptor (EGFR) signal transduction. It is currently used in the treatment of advanced stage non-small cell lung cancer and pancreatic cancer. We report a case of acneiform eruption and paronychia induced by erlotinib in a 69-year-old man. The patient visited our clinic with multiple erythematous papules and pustules on the face, periungual erythema and pus discharge, xerosis, fissures on the sole. He had taken erlotinib for the treatment of recurred lung cancer for 4 weeks. The skin lesions were partially improved with oral pyridoxine, corticosteroid and topical antibiotics.

PURPOSE: To report a case of anterior uveitis secondary to Listeria monocytogenes infection. CASE SUMMARY: A 57-year-old male presented to our clinic with ocular pain and decreased vision in the right eye for 2 days. The patient had a history of liver transplantation 2 years prior and used immunosuppressive agents. Listeria monocytogenes was identified in blood cultures 1 month before his visit. At presentation, best-corrected visual acuity (BCVA) of the right eye was counting fingers at 20 cm and the intraocular pressure (IOP) was 50 mmHg. Conjunctival hyperemia, corneal edema, keratic precipitates, and cells in the anterior chamber were observed in the right eye. The patient was diagnosed as anterior uveitis in the right eye. Conventional uveitis treatment was initiated but clinical features did not improve and black hypopyon appeared. The possibility of anterior uveitis caused by Listeria monocytogenes infection was considered. An anterior chamber tap and culture were conducted to identify pathogens. Anterior chamber antibiotic injections and systemic antibiotic injections were performed. One week after injection, the BCVA of the right eye improved to 0.4 and the IOP decreased to 14 mmHg. One month after injection, the BCVA of the right eye improved to 1.0 and the IOP decreased to 16 mmHg. No inflammation of the anterior chamber was observed. CONCLUSIONS: When nonspecific uveitis occurs in immunosuppressed patients, cultures and appropriate antibiotics should be considered because of the possibility of infection.
