Granular Cell Myoblastoma is typically encountered in the skin, subcutaneous tissue nr oral cavity, but was rarely been found in the large intestine. In a series of 110, the two were in the cecum(18). Both patients, 36-and 43-year-old women, underwent radial excision of the lesion because of the clinical impresaion of the malignancy. The other Three patients with granular cell myoblastoma of the cecum, all asymptomatic and found incidentally, have been reported. From the available data, one was a man(22) and two were women (26,27). They were 17 (27), 40(26) and 71(22) years of age. One lesion, in the cecum, was excised at laparotomy that was performed under the irnpression of acute appendicitis, and disclosed a small polypoid submucosal nodule in the cecum incidentally(27). Another lesion, in the cecum, was excised at laparotomy following the discovery of a small cecal defect on barium enema examination 9260. The other lesion, in the cecum, was found at autopsy(22), This paper reports a case of granular cell myoblastoma of the cecum, including its colonoscopic finding.

PURPOSE: The aim of this study was to evaluate the effect of dimensional stability of splinting material on the accuracy of master casts. MATERIALS AND METHODS: A stainless steel metal model with 6 implants embedded was used as a master model. Implant level impressions were made after square impression copings were splinted using 5 different techniques as follows. (1) Splinted with autopolymerizing resin and sectioned, reconnected to compensate polymerization shrinkage before the impression procedure. (2) Splinted with autopolymerizing resin just before impression procedure. (3) Primary impression made with impression plaster and secondary impression were made over with polyether impression material. (4) Splinted with impression plaster. (5) Splinted with VPS bite registration material. From master model, 5 impressions and 5 experimental casts, total 25 casts were made for each of 5 splinting methods. The distortion values of each splinting methods were measured using coordinate measuring machine, capable of recordings in the x-, y-, z-axes. A one-way analysis of variance (ANOVA) at a confidence level of 95% was used to evaluate the data and Tukey's studentized range test was used to determine significant differences between the groups. RESULTS: Group 1 showed best accuracy followed by Group 3 & 4. Group 2 and 5 showed relatively larger distortion value than other groups. No significant difference was found between group 3, 4, 5 in x-axis, group 2, 3, 4 in y-axis and group 1, 3, 4, 5 in z-axis (P<.0001). CONCLUSION: Both Splinting impression copings with autopolymerizing resin following compensation of polymerization shrinkage and splinting method with impression plaster can enhance the accuracy of master cast and impression plaster can be used simple and effective splinting material for implant impression procedure.

BACKGROUND: Seroincidence of hepatitis B virus (HBV) among Korean blood donors has not been reported. This study was conducted to calculate the seroincidence of HBV among blood donors and to estimate the risk of post-transfusion hepatitis B by donated blood in window period of infection. METHODS: HBV seroincidence was calculated among repeat-donors who had donated from Nov. 1994 through Dec. 1996. To calculate the person-years, the database of the Korean National Red Cross was used in which results for HBsAg enzyme immunoassay were filed up. The observed incidence was adjusted by interdonation interval of incident cases, who were defined as donors showing seroconversion. The risk of post-transfusion hepatitis B by donated bloods in window period of infection was estimated. RESULTS: HBV seroincidence was estimated to be 180.85/100,000 person-years. This was adjusted as 602.83/100,000 person-years by considering interdonation intervals. The risk of post-transfusion hepatitis B was estimated to be 974 units per one million of whole blood units due to be in window period of infection. CONCLUSION: The estimated seroincidence of HBV among Korean blood donors and thereby the risk of HBV transmission by donated bloods in window period of infection was about 50 to 60 times higher than those of Japan and United States of America.(Korean J Blood Transfusion 10(1): 1-4, 1999)

In this paper, two unusual cases of fetal giant lymphangiomas diagnosed before delivery is reported in 18 and 26-week pregnant woman. They were diagnosed by ultrasound. Although the cause of lymphangioma is not clearly established, they probably arise from a failure of the developing lymphatic tissue to establish normal connection with the draining lymphatics. These anomalies are most often cervical (about 70~80%) but occasionally present in the axilla (about 10%), thorax and abdomen. Lymphangioma arising at posterior nuchal region is called cystic hygroma. Lymphangioma may be divided histologically into three types ; simple, cavernous or cystic. Ultrasound examination is essential method in prenatal diagnosis of fetal lymphangioma. The differential diagnosis of these fetal lymphangioma should include meningomyelocele, benign cystic teratoma, nuchal edema, encephalocele, and subchorial placenta cyst. About 60 to 70% of lymphangioma is accompanied with chromosomal abnormalities, and most common type is Turner's symdrome (40~80%), but occasionally trisomy 21, 18, 13 and 47 XXY. But chromosomal studies of these cases showed normal findings. The 26-week fetus was IUFD at 29 gestational weeks and terminated by hysterotomy. Other 18-week fetus was terminated by vaginal delivery after intrauterine decompression.

This case was an acquired aplastic anemia patient who required a major operation for excision of a mediastinal mass. The authors previewed that the coagulation abnormalities would be developed due to major operation. Thus we decided to monitoring the coagulation function using the thromboelastography during the perioperative period and checked the complete blood count, concommitantly. The total blood volume lost during operation was 1800 ml, so we gave him a transfusion of 10 U's of platelet concentrate, 10 U's of pheretic platelet rich plasma and 5 U's of whole blood. The thromboelastography was a good guide that helped us to avoid excessive treatment of the coagulation abnormalities. We concluded that the thromboelastograhy was a reliable and effective monitoring system at the intraoperative coagulation management.
