The neurenteric cyst with associated anomalies is the result of an ectoentodermal communication that exists during embryogenesis. The variety of lesions include intraspinal cysts, congenital vertebral deformities, thoracic cyst, malformations of the digestive tract, and occasionally, dysrhaphias of the sinodermal or myelomeningocele type. A case of intraspinal neurenteric cyst in a 3-year-old boy is presented. He presented with cyclic abdominal pain, fever and constipation of 30 days' duration. These symptoms progressed rapidly into gait disturbance and left hemiplegia. A single epithelial cyst, located ventral to the spinal cord in the lower thoracic region, traversed the cleft of spina bifida of thoracic vertebrae and connected to retromediastinal cyst. The inner cyst wall was lined with pseudostratified ciliated epithelia and a few squamous cells. The cyst wall contained well-developed muscle coat, myenteric plexuses, and scattered seromucinous glands.

Hepatoid adenocarcinoma of the stomach has been designated to a primary gastric adenocarcinoma with minimum criteria of elevated serum alpha-fetoprotein and its histological resemblance to neoplastic liver cells. Of the 1,500 consecutive cases of surgically resected gastric carcinomas during a period of 4 years, we retrieved 14 cases of adenocarcinoma which met the histologic features of hepatoid growth and compared them histologically with 400 consecutive cases of non-hepatoid gastric adenocarcinomas. The patient's age ragned from 32 to 80 years(non-hepatoid group: 25 to 81 years) and their male to female ratio was 3.7 : 1(non-hepatoid group: 1.8 : 1). Grossly, five case were Borrmann type II and another five cases type III. All three cases of early gastric carcinomas were the submucosal type IIc. The remaining one was an advanced gastric carcinoma mimicking early gastric carcinoma. Microscopically, the hepatoid portions varied in growing patterns and arranged in either compact, trabecular or pseudoglandular pattern and gave an immunoreactivity to alpha-fetoprotein and alpha-1-antichymotrypsin. Regardless of the tumor stage, the hepatoid areas were located in the deeper portion of the tumor mass and grew in an expanding/nodular pattern. The associated adenocarcinomatous areas were mostly papillotubular, moderately to well differentiated, and frequently revealed clear PAS-negative cytoplasm reminiscent of the differentiated embryonal carcinoma. Tumor emboli and nodal metastasis were the frequent associations. We assume that the hepatoid adenocarcinoma may develop from gastric'adenocarcinoma through embryonal carcinomatous growth.

It has been well known that liver cirrhosis, regardless of its etiology, is an important predisposing factor in hepatocarcinogenesis. However, the type of cirrhosis in hepatocellular carcinoma(HCC)-bearing liver varies not only by geographic areas but also with the cirteria applied for morphological classification of cirrhosis. To elucidate the relationship between the nodule size of HCC-bearing cirrhotic liver and clinicopathologic features, we measured cirrhotic nodule areas of 49 surgically resected HCC cases using image analyzer. The morphological type of cirrhosis was predominantly macronodular(49%), and followed by mixed(37%) and micronodular(14%). Seventy percent of the cases showed seropositivity for HBsAg. The average area of cirrhotic nodules was significantly larger in HBsAg-positive cases(mean: 6.14 mm2) than that of HBsAg-negative cases(mean: 2.5 mm2)(p<0.05), and their size was bigger in cases with grossly expansile pattern of HCC than those cases with infiltrative ones(p<0.05). Based on the above findings, we assume that seropositivity of HBsAg may influence on the regenerative activity of cirrhotic nodules and also subsequent increase of risk for further development of HCC. The presence of cirrhohsis and nodule size seem to be the important contributing factors to determine the growing patterns of HCC.

Twenty intraocular lenses removed after periods of use ranging from 2 months to 17 years were examined by scanning electron microscopy(SEM). The lenses were retrieved from three sites, anterior chamber, iris-fixed and posterior chamber. The reasons for removal and type of lens were compared to the pathological findings and length of wear. Scanning electron microscopy showed pigment containing epithelial cells, fibroblasts and macrophages on all three categories of lens. The pathological response was not site specific. The presence of these cells on the lens surface strongly suggests a foreign body reaction by the host to the intraocular lens regardless of the duration of implantation or type of intraocular lens.

Treatment modalities of gastric variceal bleeding are endoscopic injection sclerotherapy, endoscopic variceal ligation, combined above two method, operation, TIPS, and percutaneous transhepatic embolization. Recently, Histoacryl was introduced as a new sclerosant of acute variceal bleeding failed by others. So, we studied 18 cases of acute gastric variceal bleeding uncontrolled by EIS using Ethanolamine oleate. Intravariceal injection of Histoacryl is considered as a safe and effective method for hemostasis of intractable acute gastric variceal bleeding uncontrolled by other sclerosants. But, it is important that endoscopist should be in harmony with assistant at injection of Histoacryl. And its shooting speed should be fast because of clogging within the catheter. It is necessary to do long term study for evaluation of eradication effect in acute gastric variceal bleeding.

Thirty years ago a major arterial laceration was devasting injury, threatening survival of the limb in almost every case. Increased awareness of vascular injuries and of feasibility of immediate and more advanced arterial repair techmique reduced the amputation rate. The authors reviewed 163 patients of vascular injuries in extremities, who were admitted to Severence Hospital of the Yonsei University College of Medicine from January, 1979 to December, 1986. The results were follows : 1. Among the 163 patients, 146 patients were male patients. 2. Most of the victims were in their twenties. 3. The most common cause in the upper extremity was glass injury. The most common cause in the lower extremity was being struck by moving vehicles. 4. More complications in vascular injuries were associated with severe soft tissue crushing and comminuted fracture of the bone. 5. More favorable results can be gained through the use of microvascular techniques than through conventional techniques in vascular reconstruction.

Equinus deformity of ankle, adduction and flexion deformity of hip and flexion contracture of knee are most common deformities in spastic cerebral palsy. There were many surgical treatment methods according to its causes. Authors has analysed 115 patients(224 operation) who had been operated with three procedure (Modified Egger's op, Proximal hamstring elongation, Distal hamstring elongation) and compared the results of these procedure at Sam Yook Rehabilitation Center from Jan. 1980 to Dec. 1987. The following results are obtained: 1. The results of Modified Egger's operation were unsatisfied because of complicaLion and little angle correction ability of flexion contracture of knee joint. 2. Even though there was no differences in angle correction ability of flexion contracture of knee joint between two procedures, the results of proximal hamstring elongation were superior to them of distal elongtion because early walking ability is more easily improved.
