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.

A prominent crista terminalis is a normal anatomic variant which consist of thick muscular bridge within the right atrium. However, it could be often misdiagnosed with an abnormal mass on the transthoracic echocardiography. The case report presented here, describe the findings of transthoracic echocardiography that suggested a right atrial mass in patients with pulmonary embolism. However, subsequent transesophageal echocardiography and cardiac computed tomography/magnetic resonance imaging differentiated a true right atrial mass from a prominent crista terminalis.

PURPOSE: Laparoscopy-assisted distal gastrectomy (LADG) is gaining wider acceptance for the treatment of early gastric cancer. However, firm evidence supporting the long-term outcome after LADG for gastric cancer is unknown. This study compared long-term quality of life after LADG versus an open distal gastrectomy (ODG) for early gastric cancer. METHODS: This study included 29 patients who underwent LADG and 57 patients who underwent ODG for the treatment of stage I gastric cancer. Quality of life was evaluated based on the Korean version of EORTC QLQ-C30 (version 3.0) and EORTC QLQ-STO22 one year after surgery. All patients underwent a Billroth II gastrectomy for stage I gastric cancer between January 2003 and December 2004. RESULTS: A total of 86 (58%) out of 154 patients responded to the questionnaire. Demographic features showed no difference between the two groups of patients for age, sex, depth of invasion, lymph node metastasis except for tumor size and the number of retrieved lymph nodes. The mean score for global health status was not statistically different (LADG, 60.3+/-20.4 vs ODG, 57+/-20.6; P=0.413). The total score of 21 items related to stomach cancer (EORTC QLQ-STO22) also was not statistically different (LADG, 68.9+/-64.9 vs ODG, 94.5+/-97.3; P=0.340). CONCLUSION: Based on the results of the Korean version of EORTC QLQ-C 30 (version 3.0) and EORTC QLQ-STO22, LADG does not seem to have any long-term benefit over ODG on 'quality of life'.

BACKGROUND: Arterial pressure is the most commonly utilized guideline for the management of critically ill patients. However, the site of arterial pressure monitoring can impact the observed pressure. In patients undergoing cardiac surgery, peripheral arterial pressure can underestimate central aortic pressure and vasodilators magnify this phenomenon. There was also a large discrepancy between radial and femoral artery pressure in endotoxemic patients treated with vasopressors or hypothermic patients. We evaluated the effect of the continuous infusion of norepinephrine, the most commonly used vasopressor, on pressure and blood flow in both the brachial and femoral artery in dogs in normal condition. METHODS: Both the brachial and femoral arteries were cannulated for pressure monitoring and the other side arteries were exposed for the measurement of blood flow in 10 dogs. Two doses of norepinephrine (NE), 0.05 microgram/kg/min and 0.1 microgram/kg/min, were infused for 10 minutes each in sequence. Hemodynamic variables and blood flow were measured before the infusion of NE, and immediately after the infusion of the two doses of NE. RESULTS: NE increased both brachial and femoral arterial pressures with no difference between the two pressures. NE decreased blood flow in both brachial and femoral arteries even though cardiac output was maintained constantly which means NE caused the redistribution of blood flow. CONCLUSIONS: Unlike endotoxemic shock conditions or hypothermic vasoconstriction, NE didn't show different effects on pressure monitoring sites regardless of their diameter in normal condition. NE increased blood pressure and decreased blood flow in the same degree in both the brachial and femoral artery.

PURPOSE: Tumor necrosis factor-alpha(TNF-alpha) is a pro-inflammatory cytokine that has been implicated in the pathogenesis of cardiovascular disease. Serum levels of TNF-alpha are elevated in many human cardiac related pathogenic conditions, including heart failure. It is well known that TNF-alpha inhibits myocardial contractility and induces apoptosis of adult rat cardiomyocytes via stimulation of TNF receptor 1. But pathophysiologically relevant low levels of TNF-alpha can not induce apoptosis of neonatal cardiomyocytes. So, we evaluated the effects of different concentrations of TNF-alpha in cultured rat neonatal cardiomyocytes : apoptosis or necrosis. METHODS: Neonatal ventricular myocytes were isolated from 3-day-old rats by stepwise collagenase dissociation, and the cells were cultured for 3 days. After that, cardiomyocytes were treated with low(25 ng/mL) and high(250 ng/mL) concentration of TNF-alpha for 48 hours. Apoptosis was determined by terminal deoxynucleotidyl transfer-mediated end labelling(TUNEL) staining, and cell viability was evaluated by lactate dehydrogenase(LDH) measurements using cell culture supernatants. RESULTS: Low dose TNF-alpha did not induce apoptosis compared with controls(10.5 +/- 3.5% : 10.4 +/- 4.3%). And high dose TNF-alpha also did not induce significant apoptosis(10.2 +/- 3.6% : 10.4 +/- 4.3%). There was no detectable morphological changes of cardiomyocytes after low and high concentration of TNF-alpha treatment. LDH levels after TNF-alpha treatment was not significant compared with control(control : low : high, 3.2 +/- 0.1% : 3.1 +/- 0.2% : 3.3 +/- 0.3%). CONCLUSIONS: Our results suggest that high concentration of TNF-alpha alone can not induce apoptosis and significant cytotoxicity in neonatal rat cardiomyocytes.

Nevus sebaceus is a congenital cutaneous hamartoma which has a potential to develop both benign and malignant neoplasm in late life. The most common benign tumor developed within the nevus is syringocystadenoma papilliferum and the most common malignant tumor basal cell epithelioma. Although two different tumors often develop simultaneously on the lesion, it is rare to see more than two different tumors developing on the lesion of nevus sebaceus. In Korean literatures only three such cases were reported. We report an additional case of nevus sebaceus developing three different tumors, syringocystadenoma papilliferum, sebaceous epithelioma, and basal cell carcinoma, in a 67-year-old female patient.

PURPOSE: We report a case of a male with bilateral tonic pupils associated with syphilis, that partially improved after syphilis treatment. CASE SUMMARY: A 27-year-old male presented with a 2-month history of near vision impairment. The right and left pupils were 5.5 mm and 6.5 mm in diameter, respectively, in the dark and 5.3 mm and 6.1 mm, respectively, in the light. Both pupils demonstrated light-near dissociation, slow constriction and redilation when looking at near, and constriction after instillation of 0.0625% pilocarpine. Serological tests were positive for syphilis, while cerebrospinal fluid testing was negative. Two months after treatment with intramuscular injection of benzathine penicillin G, his near vision subjectively improved and the right and left pupils were 5.9 mm and 6.4 mm, respectively, in the dark and 4.8 mm and 5.3 mm, respectively, in the light. The size of both pupils decreased and the pupillary light responses partially improved in both eyes. CONCLUSIONS: Patients with bilateral tonic pupils should have serological tests for syphilis. Recovery of tonic pupils can be expected after early treatment with effective antibiotics.

BACKGROUND/AIMS: Laterally spreading tumors (LST) were growthed along the colonic wall. These tumors were high malignant potential compared to colon polyp. We analyzed clinicopathological characteristics of these tumors. METHODS: From June 1996 to June 2001, twenty nine patients were diagnosed by colonoscopy. These lesions were classificated macroscopic (granular type and nongranular type) and microscopic findings. RESULTS: 20 male and 9 female were enrolled (mean age, 68.1). Among the LST, 41.4% were 20~30 mm in diameter, and 7% were larger than 30 mm. According to macroscopic findings granular types were 72.4% (21/29) and nongranular types were 27.6% (8/29). In macroscopic findings, tubular types were 48.4% (14/29), malignant changes were 31.3% (9/29). Tumor size was only significant factor in malignant potential of LST (p=0.004). Endoscopic mucosal resection was performed in 72.4% (21/29), operation in 8 (27.6%). Rate of submucosal invasion in LST was 3.4% (1/29, sm1). Recurrent rate of endoscopic treatment group was 9.5% (2/21). CONCLUSIONS: Most of LST were good indication for endoscopic treatment, but larger tumor size and irregular surface of tumor were suspected to be submucosal invasion. Therefore these lesions were performed other procedures as endoscopic ultrasound or computerized tomography for invasion depth.

PURPOSE: Many patients complain of pain due to fracture in the emergency department (ED). However, pain management in these patients has not been performed well. The objective of this study is to describe analgesic utilization and assess factors associated with analgesic use in patients with isolated long-bone fractures during the ED visit. METHODS: We retrospectively reviewed electronic medical records of patients presenting to two EDs with an isolated long bone fracture from January to December 2012. A total of 358 patients were enrolled, and sex, age, arrival route, mechanism of injury, fracture type, fracture location, drug used for pain control, arrival time, physician in charge primary care, and disposition were analyzed. RESULTS: Analgesics were administered to 50% of patients between 20~60 years, whereas 11.3% of patients under 20 years old and 38.7% above 60 years old (p<0.01) received analgesics. Better pain control was achieved in females, young adults, patients cared for by emergency medicine residents, and visits made by emergency medical service or at dawn. CONCLUSION: The pain control rate of children is lower than that of adults in patients with an isolated long bone fracture. Active strategies for pain management are necessary by triage physicians from this time forward.
