We present an unusual case of molluscum contagiosum occurring in epidermal cyst on back of a 5-year-old girl. Histology showed an intradermal cyst containing lamellated horny materials and typical molluscum cells. In Korean literature, 5 such cases were reported. We report an additional case of molluscum occurring in epidermal cyst.

PURPOSE: To compare the anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA) and refractive change after cataract surgery between 3-piece and 1-piece aspheric intraocular lens (IOL) implantation. METHODS: The present study consisted of 16 patients (25 eyes) having 3-piece aspheric Tecnis(R) ZA9003 IOL and 21 patients (30 eyes) having 1-piece aspheric Tecnis(R) ZCB00 IOL. The ACD, ACV, and ACA were measured using an anterior eye segment analysis system (Pentacam, Oculus, Wetzlar, Germany) preoperatively and postoperatively 1 week and 1 month. Refractive outcomes were evaluated using an autokeratometer. RESULTS: When comparing the 3-piece (Tecnis(R) ZA9003) and 1-piece (Tecnis(R) ZCB00) IOL with the same optic, ACD, ACV, and AVA increased significantly after cataract surgery. The 1-piece IOL showed deeper ACD than the 3-piece IOL at postoperative 1 week and 1 month. Postoperative refraction showed slight myopic shift compared with target diopter, but was stable in both groups. CONCLUSIONS: There was significant increase in ACD, ACV, and ACA after cataract surgery in both IOL-inserted groups. Results showed stable refraction after cataract surgery in both groups. Consideration of the A-constant will be needed because of myopic change with the 1-piece IOL.

Duodenal choriocarcinoma, either primary or metastatic, is very rare. Early diagnosis and prompt initiation of chemotherapy improve the prognosis of this neoplasm. We herein present, together with the referred literatures, a case of a 47-year-old female patient who visited to our hospital with upper intestinal bleeding. She was diagnosed as duodenal choriocarcinoma by operation. Brain metastasis was found soon after the operation and combination chemotherapy was done.

BACKGROUND/AIMS: The aim of the study was to investigate the risk factors for biliary pancreatitis according to severity. METHODS: This study retrospectively reviewed 58 patients who underwent endoscopic retrograde cholangiopancreatography for the management of acute biliary pancreatitis between November 2001 and June 2004. The severity of pancreatitis was classified as severe or mild pancreatitis according to the Glasgow scale. Multiple clinical and radiological factors were analyzed for a relationship with the severity of pancreatitis and coexisting biliary pathology. RESULTS: Ten patients (17%) had severe pancreatitis (the SP group) and the remaining 48 patients (83%) had mild pancreatitis (the MP group). The diameter of the common bile duct CBD) and cystic duct, and the number and the size of gallstones were not significantly different between the two groups of patients. The number of patients without a periampullary diverticulum in the SP group (90.0%) was significantly higher than in the MP group (39.6%). Most of the SP patients (90.0%) had CBD stones (<5 mm) or CBD sludge, but the prevalence of CBD stones (<5 mm) or CBD sludge was lower in the MP group (54.2%, p=0.04). The absence of a periampullary diverticulum was identified as a risk factor according to severity by the use of logistic regression analysis (odds ratio=25; p=0.01). CONCLUSIONS: The development of severe biliary pancreatitis was influenced by risk factors such as a CBD stone less than 5 mm or sludge and the absence of a periampullary diverticulum.

Malignant fibrous histiocytoma (MFH) is an uncommon soft-tissue sarcoma that occurs primarily in the extremities and rarely involves the retroperitoneum and abdomen. A 63-year-old man was admitted to the emergency room because of epigastric pain. Computed tomography revealed a large heterogeneous enhanced mass originating from the omentum with hemoperitoneum. The patient underwent laparoscopic omental mass excision and hematoma evacuation. Histological examination of the resected tumor revealed MFH. This case was therefore omental MFH presenting with hemoperitoneum.

PURPOSE: To estimate the long-term therapeutic efficacy and safety of adefovir dipivoxil in children and adolescents with chronic hepatitis B who have developed lamivudine resistance. METHODS: Sixteen patients (12 boys and 4 girls; ages 4.3~20.9 years; mean age 14.2 years) with chronic hepatitis B infection resistant to lamivudine therapy received adefovir (0.3 mg/kg/day, maximal dose 10 mg) orally for at least 9 months between March 2004 and April 2008. Each patient was followed up for a mean period of 27 months (range 9~49 months) until April 2008 at Kyungpook National University Hospital in Korea. Therapeutic responses to adefovir were evaluated at 12, 24, 36, and 48 months from the initiation of therapy using the Kaplan-Meier method. Response measurements included ALT normalization, HBV DNA negativization, 2 log(10) IU/mL decrement of HBeAg titer, HBeAg loss, and HBeAg/Ab seroconversion rate. RESULTS: Three (18.8%) of the 16 patients treated with adefovir showed HBeAg/Ab seroconversion. Kaplan-Meier estimates of cumulative ALT normalization were 12.5% (12 months), 43.8% (24 months), 63.5% (36 months), and 92.7% (48 months), respectively. Cumulative HBV DNA negativization was 6.7%, 30.0%, 45.6%, and 78.2% at 12, 24, 36, and 48 months, respectively. Cumulative 2 log(10) copies/mL decrement of HBeAg titer was 12.5%, 43.8%, 56.3%, and 86.9% at 12, 24, 36, and 48 months, respectively. Cumulative HBeAg loss and HBeAg/Ab seroconversion were 6.7% (12 months) and 22.2% (24 months), respectively. CONCLUSION: The long-term therapeutic efficacy of adefovir dipivoxil was favorable in children and adolescents with chronic hepatitis B who had developed lamivudine resistance. The long-term use of adefovir should be safe in children.

Negative pressure pulmonary edema is a recognized complication of airway obstruction, particularly after endotracheal extubation. The application of oxygen therapy and continuous positive airway pressure with the administration of diuretics under a rapid diagnosis usually clears pulmonary edema. We report a case of 61-year-old man who developed negative pressure pulmonary edema following extubation after an endoscopic submucosal dissection under general anesthesia.

PURPOSE: Schnyder crystalline corneal dystrophy (SCCD) is an autosomal dominant disease characterized by progressive central corneal opacification and premature development of peripheral arcus in the cornea. This disease results from a point mutation of UBIAD1 in chromosome 1p34-36. Until now, 15 different mutations of UBIAD1 gene on chromosome 1p34-36 have been reported for Schnyder crystalline corneal dystrophy. More point mutations are expected to be added to the list in the future. Schnyder crystalline corneal dystrophy is a rare disease, with only three reported cases in Korea, although there has been no report of a genetically confirmed case of the disease. CASE SUMMARY: We encountered six patients with an N102S mutation of UBIAD1, who are from a family of two generation with 12 family members. Genetic confirmation for Schnyder crystalline corneal dystrophy was performed on these patients. This was the first report of a genetic confirmation of Schnyder crystalline corneal dystrophy in Korea. We will discuss our cases along with a review of the related literature.

Background and Objectives: Previous observational studies presented a positive association between alcohol and atrial fibrillation (AF). However, previous studies using genetic polymorphisms on the causal relationship between alcohol consumption and AF have reported conflicting results. This study aimed to evaluate the causality between alcohol consumption and AF using the aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphism, which is the genetic variant with the most potent effect on drinking behavior. Methods: A total of 8,964 participants from the Dong-gu Study were included in the present study. The causal association between alcohol consumption and AF was evaluated through a Mendelian randomization (MR) analysis using the ALDH2 rs671 polymorphism as an instrumental variable. Results: No significant relationship between alcohol consumption and AF was found in the observational analysis. However, the genetic analysis using the ALDH2 polymorphism showed a significant association in men. In the MR analysis, genetically predicted daily alcohol consumption was positively related to AF. Conclusions MR analysis revealed a significant association between the amount of alcohol consumption and AF, which suggests that the association may be causal.
