Pure ovarian choriocarcinoma of germ cell origin is exceedingly rare neoplasm, and even the presence of choriocarcinomatous elements admixed with other neoplastic germ cell elements is rare. In the most cases, the tumor is admixed with other neoplastic germ cell elemeats, and their presence is diagnostic of noagsatational choriocarcinoma, except for the remote of the tumor being a geatational choriocarcinoma metasttic to an ovarian germ cell tumor. We have experienced a case of nongestational ovarian choriocarcinoma in 10 year dld woman. So we report this case with a brief review of its literatures.

As Kelsey stated “Four out of five individuals will have a significant complaint of back painat one time or another in their lives and impairment of the spine are the most frequent cause of time lost from work”., low back pain affects the quality of life for just about everyone, medical and economic impacts of low back pain are enormous. Nevertheless, neither the government not industry has been seriously involved in the study of the cause, prevention, and management of back pain. The purpose of this study was to review and analysis the clinical materials of low back painand draw differences, if any, between discogenic and stenotic low back pain. Three hundreds and fourty nine cases suffering from low back pain and/or sciatic pain, excluded fresh traumatic and inflammatory conditions of the spine, have been admitted and treated at Dept. of orthopaedic surgery, Eul-Ji General Hospital, Dae-Jeon from May, 1981 to April, 1984. They were consisted of H.N.P. (172 cases), Spinal stenosis (61 cases), Spondylolisthesis (42) cases), Degenerative joint Disease of the spine (48 cases), and Others (26 cases). Among them, two hundred and twenty six cases who were followed more than four months were mainly subjectecl to this study.

OBJECTIVE: The purpose of this study was to evaluate the efficacy and effect of various cryopreservation method on the survival and the cytoskeletal stability of metaphase II mouse oocyte. METHODS: Mouse ovulated oocytes were collected and cryopreserved by a modified slow-freezing method with 1.5 M 1,2-propanediol (PrOH)+0.1 M sucrose or by vitrification using cryo loop and EM grid with 40% ethylene glycol+0.6 M sucrose. Four hours after thawing, intact oocytes were fixed and stained with fluorescein isothiocyanate (FITC)-conjugated monoclonal anti-beta-tubulin antibody to visualize spindle and propidium iodide (PI) to visualize chromosome. Spindle morphology was classified as follows: normal (barrel-shaped), slightly and absolute abnormal (multipolar or absent). RESULTS: Survival rate of the frozen-thawed oocytes in vitrification group was significantly higher than that of slow-freezing group (62.7% vs. 24.4%, p<0.01). Vitrification with cryo loop showed significantly higher survival rate than that with EM grid (67.7% vs. 53.5%, p<0.05). On the other hand, proportion of normal spindle and chromosome configurations of the frozen-thawed oocytes between two vitrification group was not significantly different. CONCLUSION: For mouse ovulated oocytes, vitrification with cryo loop may be a preferable procedure compared to slow-freezing method. Further study should be needed to investigate developmental competency of frozen-thawed mouse oocytes.

PURPOSE: Our aim was to determine the patterns of recurrence after curative resection of gastric cancer and to analyze the factors related with recurrence. We hypothesized that aggressive surgical approach including extended lymphadenectomy performed during last several decades may alter the patterns of recurrence. MATERIALS AND METHODS: A retrospective analysis of 91 patients with recurrent gastric cancer after curative surgery at Department of Surgery, College of Medicine, The Catholic University of Korea, from 1989 to 1992. RESULTS: Average time to recurrence was 21.8+/-17.9 months and 64 cases(70.3%) were recurred in 24 months after surgery. The most common type of recurrence was peritoneal dissemination(46.2%), followed by distant lymph node metastasis(24.2%), hematogenous metastasis(19.8%), and local recurrence(7.7%). Borrmann type III and IV, serosal invasion, lymph node metastasis, lymphatic and perineural invasion were the factors associated with recurrence. In peritoneal dissemination, serosal invasion and poorly differentiated adenocarcinoma were high risk factors. Mean duration of life after recurrence was 5.4+/-5.2 months. Re-operation was performed in 12 cases(13.2%), and survival was longer in resection cases compared to non-resection cases(10.9 vs 3.8 months)(p=0.034). CONCLUSION: With the use of aggressive surgical approach, relative incidence of local recurrence has been lowered. On the other hand, peritoneal seeding was the most frequently encountered pattern of recurrence. Serosal invasion, Borrmann type III or IV and poorly differentiated adenocarcinoma were risk factors for peritoneal recurrence. Intensive follow-up examination is strongly suggested during the first 24 months after curative surgery for advanced gastric cancer because of high probability of recurrence in this period. Surgical resection for locally recurrent gastric cancer seems to prolong survival time.

PURPOSE: Struma ovarii is ovarian tumor composed solely or predominantly of thyroid tissue or tumor in which hyperthyroidism results from ovarian thyroid tissue, and usually occurs in tandem with cystic teratoma. Ovarian cystic teratoma is radiologically easily diagnosed due to calcification or fat, for example, but the preoperative diagnosis of struma ovarii is often difficult due to rare characteristic features of thyroid tissue. Our purpose was to determine whether there were specific findings of struma ovarii which distinguished it from other ovarian tumors, and this involved analysis of its radiologic findings. MATERIALS AND METHODS: Using ultrasonography, computed tomography, and magnetic resonance imaging, preoperative radiologic findings of pathologically-proven struma ovarii in eleven patients were retrospectively evaluated for site, margin, nature (cystic, solid, mixed), contrast enhancement, septa, mural nodule, calcification, fat, and metastasis. These findings were compared with pathologic findings. RESULTS: All eleven tumors were unilateral, ten had smooth tumor margins, seven were mixed cystic and solid tumors (more than 70% of solid components in one tumor), and nine had regular septa. Three of four cystic masses (one unilocular, one bilocular and two multilocular cysts) had mural nodules. Calcifications were found in two tumors, and fat in one. Malignant change or metastasis was not found in any tumor. In one patient with hyperthyroidism due to struma ovarii, symptoms and signs of this subsided after removal of the tumor on salpingo-oophorectomy. CONCLUSION: Most cases of struma ovarii occurred unilaterally within ovarian teratomas in premenopausal women, and were mixed cystic and solid masses with smooth margins that are commonly enhanced on contrast enhanced scans. In one patient, hyperthyroidism was caused by struma ovarii. There were, however, no specific radiologic findings that were sufficiently typical to suggest the correct preoperative diagnosis of struma ovarii.

Arthroscopic treatment of shoulder instability involves two techniques mainly, transglenoid suture technique and anterior anchoring system. However, anterior anchoring system has some disadvantages such as limited indication, high cost, technical difficulty and incapability to suture or reconstruct for all types of Bankart lesion. Disadvantages of transglenoid suture techniques are indirect suture tie, bump effect and possibility of the suprascapular nerve injury. The authors use modified transglenoid suture technique (Rhees method) for shoulder instability involving Bankart lesion, type II SLAP lesion and capsular laxity. The purpose of this study is to accurately describe the relationship between the major neurovascular structures and the pinning sites used in transglenoid suture technique (Rhees method). Placement of two or three arthroscopic Beath pinning sites was simulated in four fresh cadaveric shoulder specimens by placing Steinman pins into the glenoid rim under open field. The specimens were then dissected and the relationship of the pinning sites to the suprascapular nerve and suprascapular artery were recorded. In Bankart lesion repair, safe zone of pinning sites were 2 and 5 oclock in two portals in right shoulder, safe zone of pinning sites were 7 and 10 oclock in two portals in left shoulder. Safe direction of pinning was as possible as inferomedial side in scapula. In type II SLAP repair, safe zone of pinning sites were 2 oclock and just above 2 oclock of glenoid in right shoulder and 10 oclock and just above 10 oclock of glenoid in left shoulder. Safe direction of pinning was pararell to glenoid cavity and slightly superior in horizontal plane. From this study, these sites and directions appeared to be safe. Proper pinning depends on careful attention to the topographical anatomy about the shoulder.
