The Epstein-Barr virus(EBV) is known to play a causal role in oncogenesis and to be associated with endemic Burkitt's lymphomas, B cell lymphomas in immunocompromised patients, and nasopharyngeal carcinomas. More recently, EBV has also associated with Hodgkin's disease, B cell lymphomas in non-immunocompromised patients, and T-cell lymphomas. Twenty eight cases of a non-Hodgkin's lymphoma of gastrointestinal tract were investigated to determine both the immunophenotype by using immunohistochemical staining and the incidence of the EBV nuclear antigen by using the polymerase chain reaction. Twenty-four of the 28 cases(85.7%) were B-cell type, and 4 of the 28 cases(14.3%) are of T-cell type. The EBV nuclear antigen was detected in three of the 28 cases(10.7%), including two cases of B-cell lymphoma of the stomach and one case of T-cell lymphoma of the small bowel. The EBV nuclear antigen was more frequently found in malignant lymphomas arising in the intestine(1/4) than in stomach(2/16). EBV positivity (25%) in T-cell NHLs was rather higher than EBV positivity (8.3%) in B-cell NHLs. Further expanded evaluations on the role of EBV in the tumorigenesis of a gastrointestinal malignant lymphomas are necessary because the cases of gastrointestinal lymphomas examined were very limited.

BACKGROUND: The purpose of our study was to evaluate the functional and radiologic outcomes of additive augmentation sutures through rotator cuff for proximal humeral fractures stabilized locking plate in elderly patients. METHODS: We enrolled 74 patients over the age of 60 years who received internal fixation using locking plates for proximal humeral fractures. Of these, 50 patients had additive augmentation sutures through rotator cuff. The mean age at the time of surgery was 72.1 years (range, 60-89 years), and the mean follow-up period was 17.5 months (range, 12-62 months). The humeral neck-shaft angle and humeral head height were used as radiological markers to assess the effect of additive augmentation sutures through rotator cuff. We allocated the patients who received additive augmentation sutures into group A and those who did not into group B. RESULTS: At the final follow-up, the mean Korean Showlder Society score and Constant scores were 88.96 +/- 12.1 and 86.6 +/- 11.9, respectively, in group A and 86.21 +/- 11.8 and 85.3 +/- 11.7, respectively, in group B (p=0.368, 0.271). At the final follow-up, the mean loss in humeral neck-shaft angle from the time of immediate postoperative measurement was 1.6degrees in group A and 4.8degrees in group B, whereas the mean loss in humeral head height was 0.82 mm in group A and 0.52 mm in group B (p=0.029, 0.178). CONCLUSIONS: The surgical outcomes of internal fixation using locking plates for proximal humeral fractures were clinically and radiologically good in elderly patients over the age of 60 years without any observable complications. Further, the loss of humeral head shaft angle at the final follow-up from its initial postoperative measurement was significantly smaller in patients who received an additive augmentation suture than in those who did not. Thus, we conclude that augmentation sutures are a beneficial option for elderly patients that clinicians can consider at the time of surgical decision making.

Although the reconstruction with tumor prosthesis is a routine procedure for extremity sarcomas, this option has some technical limitation in children under 10 years old. Customized expandable tumor prosthesis is too expensive in most cases and arthrodesis of any kind is not functional. This report presents one case of osteosarcoma of distal femur in eight years old child which was reconstructed with adult type total elbow endoprosthesis as a reconstructive option, and includes brief review of the literature.

Osteochondroma, the most frequent benign bone tumor, is composed of trabecular bone covered with a hyaline cartilage cap. It is well known that multiple osteochondromatosis may undergo malignant change. Such sarcomatous change usually present with the form of chondrosarcoma, and transformation to other malignancy is extremely rare. This report describes one case of osteosarcoma arising in patients who had multiple osteochondromatosis, and includes brief review of the literatures.

PURPOSE: Patients with hematologic diseases such as chronic myeloid leukemia (CML) or chronic lymphoid leukemia (CLL) are known to have an increased chance of acquiring a secondary neoplasm. Stomach cancer is one of the most common malignant diseases in Korea, and we investigated whether the incidence of secondary stomach cancer in patients with a hematologic disease increases, in order to determine if a more intensive screening program for detecting secondary gastric cancer was required. We also investigated the safety of performing a gastrectomy in hematologic disease patients. MATERIALS AND METHODS: From 1992 to 2006, the medical records of 8376 patients diagnosed with one of the six common hematologic diseases were reviewed. RESULTS: Nine secondary stomach cancers were found among the 8376 patients during the 15-year observation period. No surgical-related complications occurred, and there was no recurrence of stomach cancer if detected early. CONCLUSION: It seems that a more intensive screening program for detecting secondary gastric cancer in hematologic disease patients is not required, and surgery is not risky in these patients.

Malignant melanoma is the most common metastatic tumor of the gastrointestinal tract and can present with fairly common constitutional symptoms. A 36-yr-old woman was found to have a secondary malignant melanoma in the terminal ileum with profuse aneurysmal dilatation, which is not the typical presentation of the malignant melanoma in the small intestine. Radiologic studies revealed a large tumor involving the distal ileum with aneurysmal dilatations having afferent and efferent loops, which needed to be differentiated from malignant lymphoma and other gastrointestinal tumors. Exploratory laparotomy was done, and we found a huge mass with plentiful aneurysmal dilatations; much the same of the findings from the previous studies. Segmental resection with the surrounding omentum was done followed by end-to-end anastomosis between both ends of the remaining ileum. She had been free from any evidence of the local or systemic recurrence for one year after the completion of eighteen months of the subcutaneous interferon treatment; postoperatively however, the occurrence of metastatic mass at the right axilla rendered us from complete resection due to severe penetration into the vital nerves and vessels in the axilla.

Patients with alloantibody should be transfused with specific antigen negative blood, and in the case of autoantibody, the least incompatible blood on crossmatching can be transfused. Yet any transfusion cases that possessed autoantibody with the apparent antigen specificity have been rarely reported. A 62 year-old-woman with chronic renal failure underwent tests showing that the direct antiglobulin test was positive (2+) for IgG, the autocontrol test was positive, and the Rh phenotype of her erythrocytes was typed as group CcDEe. One unit of the e-positive packed red cells (PRCs) was transfused before an antibody identification test identified this antibody as autoantibody with an apparent e antigen specificity, but the level of hemoglobin increased from 6.3 g/dL to 7.4 g/dL without a hemolytic reaction or other transfusion side-effects.

Since coronary arteriovenous fistula(CAVF) was first reported by Krause in 1865, more than 400 cases have been reported. It is relatively rare disease and originates more commonly in the right than in the left coronary artery. We report a case of CAVF between right coronary artery and right ventricular inflow tract with significant left to right shunt in a 34-year old female who was admitted for the cardiomegaly on routine chest X-Ray. It was detected by transthoracic and transesophageal echocardiography, and confirmed by cardiac catheterization and coronary angiography. The opening of the fistula draining into the right ventricle was obliterated with sutures. There was no significant shunt in postoperative cardiac catheterization and coronary angiography.

BACGROUND: Recently, transfusion by component blood products instead of whole blood has gradually increased. And also filtered and/or irradiated blood products for the prevention of GVHD and other transfusion reaction has been used. To probe trends of recent transfusion, we analysed the use of blood components from 1989 through 1996 in Chonnam University Hospital. METHODS: We reviewed blood bank records from 1989 through 1996 in Chonnam University Hospital. RESULTS: 1. Total numbers of transfused blood units from 1989 to 1996 were 369,326 and the rate of component transfusion increased from 24.5% (1989) to 99.6% (1996) in Chonnam University Hospital. 2. Total numbers of transfused whole bloods were 5,569 units (24.5%) in 1989, then declined to 327 units (0.5%) in 1996. 3. Transfusion of PRC increased from 9,325 units (41.1%) in 1989 to 24,368 units (35.8%) in 1996, and also FFP from 7,371 units (32.4%) in 1989 to 15,546 units (22.9%) in 1996. 4. Use of platelet concentrates increased 16.4-fold from 2,223 units (2.5%) in 1989 to 36,531 units (46.8%) in 1996. 5. In 1996, percentage of filtered and irradiated blood products was 32.3% from cellular blood products. 6. With the use of the advanced blood seperator, hemapheresis showed slight increase annually. CONCLUSION: This paper will provide the basis of blood supply in Chonnam University Hospital and blood center.
