Clostridium perfringens is an anaerobe responsible for a wide range of diseases in animals and humans. Symptoms associated with C. perfringens food poisoning are caused by enterotoxin expressed only during sporulation of C. perfringens. It has been known that only 6% of global C. perfringens isolates carry the enterotoxin gene. We found 2 strains of enterotoxigenic C. perfringens out of 33 strains isolated from various sources in Korea using PCR. It was also found that these two strains were both type A that were strongly associated with food poisoning by checking the presence of four major lethal toxins (a-, B-, e-, l-toxin) using PCR. These results suggest that foodborne illness caused by C. perfringens may be common in Korea and that public education is necessary to prevent contamination of foods by this organism.

A Statistical observations were done on 587 pediatric patients who were diagnosed as having congenital heart disease by cardiac catheterization angiography and operation at Dong San Hospital Keimyung University, during the period of January 1982 to june 1987. The results were as follows 1) Out of 587 patients, 317 cases were male and 276 cases were female. There were female preponderance in atrial septal defect and patent ductus arteriosus, whille in male tetralogy of Fallot, pulmonary stenosis, and ventricular septal defect. 2) The incidence of congenital heart disease were as folliws;ventricular septal defect 35.7% tetralogy of Fallot 17.5%, patient ductus arteriousus 13.9%, arterial septal defect 7.5% and pulmonary stenosis 2.9%. 3) Most of the patients were visited hospital for the first time between the age of 2 and 10 years. 4) Assosiated anomalies of major congenital heart disease were as follows:the most commonly associated anomaly in ventricular septal defect were pulmonary stenosis and patent ductus arteriosus. Pulmonary stenosis was frequently associated with atrial septal defect. Right sided aortic arch and pentalogy were assosiated with tetralogy of Fallot. The mitral regurgitation was associated with patent ductus arteriosus mostly. 5) The overall surgical mortality was 6.8%. The mortality was high in tetralogy of Fallot(16.1%), transposition of great vessels(28.5%).

Ecthyma Gangrenosum is a rapidly progressing skin infection charact,erized by edema, hemorragic bullae and necrosis. Ecthyma Gangrenosum occurs almost exclusively in severely imrnunocompromised patients during the course of pseudomanas aeruginosa septisemia. A 5 month-old boy was transferred to our department because of multiple well defined central necrotic black-colored large erythematous bullae. In the bacterial cultures of skin, stool and liver aspiration fluid, Pseudomonas aeruginosa was grown. In the abdominal ultrasonogram and computed tomogram, the multiple liver abscess, hepatomegaly and ascites were shown on both hepatic lobes. Herein we report a case of ecthyma gangrenosum associated with liver abscess.

BACKGROUND: The diagnostic significance of ECG ergonovine test and the incidence of vasospastic angina in patients with chest pain are still uncertain. METHODS: From May 1998 to June 1999, 133 consecutive patients with chest pain were admitted for diagnostic coronary angiography. ECG ergonovine provocation tests were performed in 64 patients who have a clinical history suggesting vasospatic angina, including 27 of 28 patients with vasospastic angina documented electrocardiographically, or who's coronary angiographic findings could not be explained by their clinical history. Ergonovine was administered intravenously in incremental dose of 0.05, 0.1, 0.2, 0.3, 0.4 mg up to total cumulative dosage of 1.0mg during coronary angiography(41 cases), in the exercise laboratory(21 cases) or both(2 cases). RESULTS: Of 133 patients with chest pain, vasospastic angina was documented in 32(24%), unstable angina in 52(34%), stable angina in 10(8%), and others in 39(29%). Angiography demonstrated coronary spasm in 4 additional patients as well as 22 patients with vasospastic angina documented electrocardiographically, but ergonovine tests in the exercise laboratory showed positive response in 5 of 6 patients with vasospastic angina documented. Among the 25 patients with coronary spasm proved angiographically during ergonovine test, ECG findings at the time of coronary spasm were ST segment elevation in 21(84%), depression in 1(4%) and no change in 3(12%) patients, who had branch vessel spasm, 3 vessel spasm or incomplete spasm on coronary angiogram. Of the 31 patients with vasospastic angina who underwent ergonovine tests, positive response occurred in 24(77%) after a cumulative dose of < or = 0.4mg and in additional 3(10%) after the higher dose of >0.4mg. However the other 4(13%) had no ECG changes even after the higher dose(>0.4mg) of ergonovine. CONCLUSION: This results suggest that vasospastic angina appear to be a common cause of chest pain, and ECG ergonovine test with high dose can improve diagnostic sensitivity but cannot detect some patients with vasospastic angina.

BACKGROUND: Type VII collagen is a relatively low abundance extracellular matrix protein among the collagenous molecules. Among the minor collagens. type VII collagen has been demon strated by a immunolocalization studies to be component of anchoring fibrils and structures extending perpendicularly from the lamina densa to the upperpapillary dermis. OBJECTIVE: The purpose of his study is to determine the expression of the type VII collagengene in a group of scleroderma patients as compared to normal skin. METHODS: We have examined the levels of type VII collagen mRNA using quantitative reverse transcription PCR and in sit gybridization in scleroderma skin fibroblasts. Immunofluorescent staining with anti-type VII collan antibody was performed in vitro and in vivo to evaluate the expression of type VII collagen at protein level. RESULTS: 1. the ratio of type VII collagen/GAPDH RT-PCR product were 63.3+/-15.3 in scleroderma and 21.7+7.6 in normal fibroblasts by RT-PCR. 2. The expression of type VII collagen mRNA was considerably lower than type I in scleroderma. A few positive signals by in situ hybridization with type VII collagen cDNA were shown in the dermis. 3. The staining was markedly enhanced in scleroderma fibroblasts and tissues compaired with normal subjects in imunofluorescent staining with anti-Type VII collagn antibody. CONCLUSION: RT-PCR and immunofluorescent staining with antibodies to type VII collagen shows enhanced gene expression in scleroderma skin fibroblasts These data suggest that type VII collagen may be the main soruce of the sclerotic change of skin in scleroderma.

BACKGROUND: Dermatologic emergency patients who visit the emergency room increase in number every year. But there is no report about the statistical analysis of such visits. OBJECTIVES & METHODS: We reviewed 326 new dermatologic emergency patients who uisited the emergency room of Dongsan Medical Center in Taegu from 1986 to 1995 to study the age, sex, monthly and yearly distributior, arrival time, length of visit, prevalence of common dermatoses, admission rate and death rate. RESULTS: The results are summarized as follows: 1. Of 326 patients, there were 151 males and 175 females. The sex ratio of male to female was 1: 1.15. The number of patients increased with each year. 2. In age distribution, there were 23(7%) under 10;46(14%) between 11-20,55(17%) between 21-30;49(15% ) between 31-40;33(10%) between 41 50; 62(19% ) between 51-60 years,39(12% ) between 61-70 and 19(6%) between 71-80 years. 3. In monthly and arrival time distribution, the peak month incidence occurred in August(24 %), and the lowest incidence in December(1%). The peak incidence of arrival time occurred PM 6-12 hours and the lowest incidence AM 0-6 hour. 4. In the distribution about length nf visit, 73% of patients stayed more than 10 hours, 23% 5-10 hours and 4% less than 5 hours. 5. Of the most common derrnatoses, acute urticaria was seen in 124 cases(38%), and herpes zoster. in 94 cases (29%). In age distribution, acute urticaria was most preualent between the age of 0-30 and herpes zoster between 50-70. 6. The admission rate was 43%(140 cases). The death rate was 1.2%(3 cases). CONCLUSION: Our study of e nergency patients revealed that dermatologic emergency patients who visited the emergency room had increased in number every year and the distribution of patients is quite different from that of outpatients.

PURPOSE: The purpose of this study was to compare stress distributions of implant-supported crown placed in fibula bone model with those in intact mandible model using three-dimensional finite element analysis. MATERIALS AND METHODS: Two three-dimensional finite element models were created to analyze biomechanical behaviors of implant-supported crowns placed in intact mandible and fibula model. The finite element models were generated from patient's computed tomography data. The model for grafted fibula was composed of fibula block, dental implant system, and implant-supported crown. In the mandible model, same components with identical geometries with the fibula model were used except that the mandible replaced the fibula. Vertical and oblique loadings were applied on the crowns. The highest von Mises stresses were investigated and stress distributions of the two models were analyzed. RESULTS: Overall stress distributions in the two models were similar. The highest von Mises stress values were higher in the mandible model than in the fibula model. In the individual prosthodontic components there was no prominent difference between models. The stress concentrations occurred in cortical bones in both models and the effect of bicortical anchorage could be found in the fibula model. CONCLUSION: Using finite element analysis it was shown that the implant-supported crown placed in free fibula graft might function successfully in terms of biomechanical behavior.
