Synovial cysts are uncommon lesions that may occur within the spinal canal. Most commonly synovial cysts arise from degenerative apophyseal joints, in particular at the L4-5 level, and are associated with spondylolisthesis. We present one case of lumbar synovial cyst located both intraspinally and extraspinally and originated from the defect of the pars interarticularis. The content of the synovial cyst was infected. The patient progressively developed low back pain and fever. The lesion was diag nosed by computed tomography and a magnetic resonance imaging. The synovial cyst was presented a huge lobulacted intraspinal and extraspinal mass and connected with the L4-5 facet joint on the right side. The dural sac was displaced by the intraspinal mass. Relieve of symptoms was achieved with decompressive laminectomy and removal of the mass. The content of the synovial cyst was infected with Staphylococcus aureus confirmed by the synovial fluid culture. The reasons for our report are to describe the previously unreported appearance of this lesion that was huge lobulated intraspinal and extraspinal mass with infected fluid content originated from the defect of the pars interarticularis.

Pathological study was performed on the 135 cases (137 lesion) of early gastric cancer (EGC) diagnosed during the period from 1970 to 1988. The gastrectomy specimens were obtained from Pusan National University Hospital and Pusan Paik Hospital. The statistical analysis was applied on the point of pathological and epidemiological aspects. The results obtained were summarized as follows: 1) The proportion of patients with EGC of all gastric cancer diagnosed in Pusan area during the period of 1970 to 1974 was 1.3%, those during 1975 to 1979 was 1.7%, those during 1980 to 1984 was 7.8%, and those during 1985 to 1988 was 20.0% respectively. 2) The model age group was 6th decade in both sexes. The average age of patients with EGC was 50. 1-year-old in men and 47. 9-year-old in women respectively. The sex ratio (M/F) was 2 : 1 but it was lower for young people than for old people. 3) The proportion of sites involved by the EGC in the stomach was as follows : the antrum 61%, the body 39%, and the cardia and fundus 0.01%. The intestinal type cancer more frequently involved the lower portion than the upper portion of the stomach. 4) Regarding the distribution of the gross types of EGC, the elevated group (Type I, IIa) accounted for 14%, the flat type (Type IIb) accounted for 4%, and the depressed group (Type IIc, III) accounted for 82%. There was no correlation between the gross type and the depth of the lesion. The elevated group was more frequent in intestinal type than in diffuse type. 5) The size distribution of the EGC was as follows : 46% of the lesions were smaller than 2.0 cm in diameter, 47% were between 2.1 to 5.0 cm, and 7% were larger than 5.1 cm. There was no correlation between the size of the lesion and the gross type. 6) The intestinal type of EGC was 77 lesions (56.2%) and the diffuse type 60 lesions (43.8%). The ratio of both types (I/D) was 1.3 : 1, and it was lower for younger people than for old people. 7) Ten of 135 cases (7%) had lymph node metastases. The metastatic rate of EGC confined to submucosa was much higher than that of EGC confined to mucosa only, but the metastatic rate was not related with the size of the lesion.

Bilateral jumped facets dislocation in upper thoracic spine is rare injury because the thoracic spine is relatively immobile structure. We experienced a case of T2-3 dislocation without fracture and successfully reduced the dislocation after partial resection of the superior articular process of the third thoracic spine and performed fixation and fusion from T1 to T4 with pedicle screw system.

Purpose: The purpose of this study was to evaluate the mortality of patients over eighty years old with femoral neck fractures that have been treated with bipolar endoprostheses. Materials and Methods: We retrospectively studied 37 patients out of a total of 83, who suffered from hip fractures and were treated with surgery from 2000 through December 2004. We attempted to distinguish the differences between the 8 patients who died (Group A) and the 29 patients who lived (Group B). The variables that we analyzed, were: age, sex, operative time, the time period from admission to surgery, the time period from admission to discharge, the ASA score, and any medical comorbidities. Results: In Group A, 2 patients died within 1 month, 2 died between 1 and 6 months, 1 died between 6 and 12 months, and 3 died after 1 year. There were statistical differences between Group A and Group B with respect to two variables: the time period from admission to, and medical comorbidities. Conclusion: There were significant correlations with an increase in the mortality rate among patients with lung disease, female patients in general, and delays in surgery. Therefore, particular care should be paid to patients with these variables.

A case of primary gastric carcinoma with patterns resembling those of hepatocellular carcinoma(HCC) is reproted. This patient who represented high serum alpha-fetoprotein(AFP) underwent a subtotal gastrectomy for stomach cancer and lobectomy of liver metastasis. The hepatoid component of the tumor was characterized by solid nests of large polygonal cells arranged in cords and trabeculae, with central nuclei, prominent nucleoli, and abundant eosinophilic cytoplasm; single-nuclear giant cells were frequently noted. These tumor cells of stomach stained positive immunohistochemically for AFP, ACT(alpha-1-antitrypsin), AACT(alpha-1-antichy-motrypsin). Thus, this hepatoid gastric adenocarcinoma tumor cells demonstrated both morphologic and immunohistochemical features of partial differentiation to the HCC. Careful histologic examination in conjunction with the immunohistochemical demonstration of AFP can provide a useful contribution to the diagnosis of this rare histological type of gastric carcinoma And the presence of metastatic hepatoid adenocarcinoma from the stomach should be considered in a patient with hepatic tumor mimicking HCC. Because of frequent venous and lymphatic invasion, as well as liver metastasis, prognosis appears to be poor. The authors reviewed 45 cases of hepatoid adenocarcinoma of stomach reported in the literature, also.

Slipped capital femoral epiphysis is a rare disease in Korea, but the incidence has being increased according to the changes of body contour and life style. Now we have more concern about slipped capital femoral epiphysis, especially the factors which contribute to the final result of treatment. Many factors such as severity of slip, stability of slipped epiphysis, whether closed reduction was done or not, whether severe complication like avascular necrosis or chondrolysis has occurred or not have effect on the result. We analyzed 20 cases of slipped capital femoral epiphysis, which occurred in 16 adolescence in view of which factors contributed to the final satisfactory result. In our study, the difference in the duration of symptoms, instability of slipped epiphysis, patients age, association with obesity or acute trauma and the number of pins had much effect on the final results and whether the reduction was done or not, the kinds of pins and association with endocrinopathy made a little difference. But further studies are necessary because the number of cases is not sufficient and the length of follow up period is not long.
