Torn discoid lateral meniscus has been numerously reported in diagnosis and treatment. But discoid meniscus in children of which clinical pictures were thought to be different from adults was rarely known. We experienced 2 cases of discoid meniscus tear in children whose ages were below 4 years old and report with references.

Association of the hepatoid and choriocarcinomatous components in adenocarcinoma of the stomach is extremely unusual and raises a possibility of new approach understand the histogenesis of gastric hepatoid adenocarcinoma. This paper describes a Borrmann type III adenocarcinoma of the stomach with both choriocarcinomatous and hepatoid components in composite tumor pattern in a 50-year-old man. Tubular arrangement of differentiated embryonalcarcinoma was encountered in choricarcinomatous and hepatoid areas, which showed strong immunoreactivity to beta-HCG and AFP, respectively. The findings suggest that gastric adenocarcinoma may have a potential of differentiation toward embryonal carcinoma. from which both choriocarcinoma and hepatoid variant of gastric adenocarcinoma may develop by retrodifferentiation.

The duodenal lipoma is infrequent and few reports deseribed its endoscopic features, We recently encountered one case of duodenal lipoma which was large polypoid one in the descending portion of the duodenum. The patient had been suffred from epigastric dull pain and bloating sensatio for 5 months. We did endoscopic polypectomy of the lipoma successfully.

Childhood chronic abdominal pain usually doesn't have an organic etiology. It may cause social impairment and emotional distress in children as well as their families. In view of cognitive and behavioral aspect, passive coping style, maladaptive social modeling, and reinforced secondary gain could contribute to the development and maintenance of pediatric somatization. Integrative etiological model includes biological factors due to the enteric sensitization process, psychosocial factors which encompass family influences, psychodevelomental vulnerability, and life event-related stress. These factors interact with each other and manifest as various psychosomatic symptoms. In the treatment of childhood chronic abdominal pain, multimodal treatment program, which includes cognitive behavioral therapeutic methods, emotional support, family education, selective serotonin reuptake inhibitor, and so on, is known to be most effective.

Vascular ingrowth is essential for the survial of the graft tissue. The purposes of this study were to evaluate any changes in signal intensity of cqropreserved meniscal allograft with time in the magnetic resonance images(MRI) and to demonstrate the viability of the grafts. Eight patients underwent meniscal transplantation with cryopreserved allcgrafts using the bone block technique. MRIs of the knee were taken at 3 days, 3 weeks, 6 weeks, 3 month, 6 months. And I year after the implantation. A second-look arthroscopy and a small meniscal biopsy(sized 2mm x 2mm1 at the peripheral and central part of the meniscus were conducted at 3 months and 1 year. Three days after the operation, the signal intensity of the implanted meniscus revealed a homogenrous low signaJ intensity that could not be differentiated from that of' a contralateral normal meniscus. At 3 weeks, a high signal intensity appeared at the periphery of the meniscus. This signal, which did not communicate into the joint space, fuither intensified at 6 weeks. The high signal intensity of the meniscus, though still higher than that of the normal meniscus, decrexsed slightly at 3 months and continued to decrease progressively even a year after the implantation. The second-look arthroscopy revealed that the grafts were viable and that there was no tearing or shrinking of the meniscus. Cellular proliferation was also found at the central edge oi' the meniscus at 3 months. This cellular pattern differentiated from that of a nonmal meniscus in that the d stribution of cells was not in an even, but in a clonal pattem. The cellularity after a year, however, was sirnilar to that of normal meniscus except some area with deficiency of cells. It can be concluded that increased signal intensity of' the implanted meniscus with time indicates hypervascularity caused by vascular ingrowth, similar to the high signal intensity ot>tained from normal meniscus in young children. Increasecl signal intensity in the chronological postoperative MRls demonstrates the viability of the implanted cryopreserved meniscal allograft.

Fractures involving both tibial plataeus result form high energy trauma such as a traffic accidents or falls, and it is frequently accompanied by soft tissue injuries. Thus it is very difficult to treat these fractures satisfactorily and severe complications can be caused. The purpose of study is to analyze the clinical results, complication and factors influencing the results after open reduction and internal fixation of tibial bicondylar fractures. Twenty cases(19 patients) of tibial bicondylar fractures which had been treated by open reduction and internal fixation from January 1989 to December 1994 were analyzed after 1 to 5 years follow-up. The results were as follows. 1. By AO classification, the most common type was C3(13 cases). 2. According to Blokker's criteria, 5 cases was unsatisfactory and all of these cases were C3. 3. Unsatisfactory results were 3 cases of reduction loss(angular deformity), one case of deep infection and one case of unresolved peroneal nerve palsy. 4. Tibial tubercle osteotomy, bone graft and medial buttress plate were important for anatomical reduction and maintenance.

OBJECTIVE: The purpose of this study was to evaluate of course of delivery & perinatal outcomes for postterm pregnancy compared with fullterm pregnancy. METHODS: This study included 360 cases of postterm pregnancy out of 16,992 cases delivered at Department of Obstetrics and Gynecology from January 1, 1993 to December 31, 1997. 16,143 cases of full term deliveries of 38 to 42 gestational weeks conducted in same period were used as the control group. Postterm pregnancy was defined as a pregnancy that it exceeds 295 days calculated from first day of the last menstrual period. RESULTS: The incidence of postterm pregnancy was 2.13% with the highest incidence occurring in the 26 ~30 years age group. This study group was significantly different from the control group in the incidence of fetal distress (10.28% vs. 2.20%), large fetus (10.83% vs. 6.95%), perinatal death (1.67% vs. 0.27%). CONCLUSIONS: Adverse perinatal outcomes were increased markedly as the gestational weeks to be prolonged. Therefore, careful prenatal care, accurate determination of delivery date is very important.
