BACKGROUND: Platelet aggregation and thrombus formation within the coronary artery are major factors in acute coronary syndrome. The platelet glycoproteinIIb/IIIa receptor is a pivotal mediator of platelet aggregation. Recently there have been reports that the genetic polymorphism of GPIIIa is an inherited risk factor for coronary artery thrombosis. This study investigated the relation between the Pl(A) polymorphism and coronary artery disease in Korean patients. METHODS: One hundred patients with acute myocardial infarction and unstable angina were enrolled. Coronary angiogram was performed in eighty-one cases. Genomic DNA from peripheral blood was amplified by polymerase chain reaction. Allele-specific restriction digestion was used to determine the Pl(A) genotype. RESULTS AND CONCLUSIONS: The prevalence of Pl(A2) genotype was zero percent in our study group. All patients had the Pl(A1/A1) genotype. These results suggest that Pl(A) genetic polymorphism of GPIIIa is not an inherited risk factor for coronary artery diseases in Koreans.

Three-dimensional solid model has not been widely used in surgical prediction of orthognathic surgery because freque from occlusal restorations or prosthesis limited the usefulness of simulated surgery involving occlusion. We prepared three-dimensional(3D) solid model from CT data and integrated the 3D solid model with dental cast using a face-bow transfer technique combined with skeletal reference measurement and confirmation with cephalometric radiographs. With this simple and easy method, it was possible to predict bony interference between the proximal and distal segment of the mandible so that we can prevent condylar displacement after sagittal split ramus osteotomy of the mandible with prominent asymmetry. The method error was within 2mm and it seemed to be useful in preoperative planning for maxillofacial surgery with maxillo-mandibular occlusal change

We report a case of myiasis on the left submandibular area after radiation therapy for squamous cell carcinoma. A 77-year-old man visited our hospital, 7 weeks after complicating a course of radiation therapy, had a 7cm diameter necrotic ulcer on the left submandible. The margin of the lesion were undermined by numerous interlinking passages containing 20 maggots. The maggots were removed by simple extraction and were identified as Calliphoridae Lucilia. The probable origin of the myiasis in this case was attributed to poor environmental condition and general weakness of the patient. Oppotunistic cutaneous myiasis can be prevented by protecting open wounds from flies, wound should not be left without a covering capable of excluding flies, especially in the summer month.

PURPOSE: It is important to have the epidemiologic data of rotavirus serotypes for the application of polyvalent rotavirus vaccines. Epidemiological studies of rotavirus serotypes in Korea have been reported only in limited areas with small number of cases. Authors tried to investigate the distribution of rotavirus G serotypes in ChungJu area with RT-PCR. METHOD: Stool specimens were collected from 202 children with acute diarrheal symptoms, who admitted to or visited Kon-Kuk University Hospital in ChungJu from June 1998 to May 1999. Samples were screened for rotavirus with EIA method (TestPack Rotavirus, Abbott Laboratories) and rotavirus G Serotypes were determined by RT-PCR. RESULTS: Rotavirus was positive in 46.6%. The incidence of G serotypes was as follows; G1 10%, G2 10%, G3 28%, G4 26%, and G9 20%. There were three cases of multiple serotypes; G1 with G9, G2 with G9, and G4 with G9. Serotype of G8 was not found. CONCLUSION: The proportion of G serotypes in ChungJu is much different from previous reports. Serotype of G9 was found which had not been reported in Korean children till now. Long term plans for the investigation of rotavirus serotypes must be needed in wide area.

Extrapelvic endometriosis is a fairly rare phenomenon. The majority of extrapelvic endometriosis involves scar tissue following obstetric or gynecologic procedures. Abdominal wall endometriosis secondary to cesarean section is a very rare condition, being reported in less than 0.5% of patients undergoing cesarean section. It has a distinct presentation and treatment. An abdominal mass with noncyclical symptoms is a common presentation. Imaging techniques are nonspecific and needle biopsy may confirm the diagnosis. Wide excision is the treatment of choice for abdominal wall endometriosis as well as for recurrent lesions. A patient with a history of cesarean section presented with a painful, enlarging mass. The pain was cyclic and aggravated just prior to menstruation. The patient was treated with surgical scar excision pathologically confirmed as endometriosis. We present this case with a brief review of literature.
