BACKGROUND: Oncogenes and EGF-Receptor(EGFR) may be involved n different stages of the multistep carcinogenesis process. A specific pattern of karyotypic abnormalities in solid tumors can be detected by cytogenetic methods. OBJECTIVE: This study is intnded to observe the cytomolecular kiologic chracterization of c-myc, erb B and EGFR genes in squasnous cell carcinoma(SCC) of the skin and cervix. METHODS: We have eytogenet,ically examined the short-term culturs from SCC. The rearrangement, amplification or expressi.on of erb B, c-myc, and EGFR genes were studied by Southern blot, analysis of genomic DNA and by slot blot analysis of tota! RNA extracted from biopsies of normal skin and SCC tissues. EGFR expression was examined immunohistochemially using monoclonal antibodies and the localizat,ion of the c-myc oncogene mRNA by in situ hybridization. RESULTS: A remarkably structural aberration was del 6(q21-qter) counted 20 metaphases among 28 metaphases ana1yzed. In nunierical aberration, all chromosomes were lost or gained randomly. Amenploid including triploid and tetraploid were observed in 8 metaphases, 6 tumor cells contained marker chromosome. In Southern blot analysis, rearrangement and amglificaton of EGFR in primary squamous cell carcinoma of cervix uteri and skin respectively. In slot blot analysis, the levels of c-myc, erb B and EGFR mRNA increaaed respectively 3.5, 2.5 and 2.8 times in SCC when compared to normal tissues. In immunoperoxidase stain, EGFR was present, in SCC where keratinocytes with strong cyto-plasmic staining but no membr, line labelling, where as in normal skin the were primarily present in t,he membrane and cytoplasm of basal cells. In situ hybridization with c-myc cDNAs allowed detection of grains representative of biotin labelled cDNA-mRNA hybrids in the frozden section of SCC tissues. CONCLUSION: These results suggest that specific patterns of karyotypir abnormalites, rearrangement, or amplification of EGFR gene, and overexpression of oncogenes and EGFR gene may be associated with the carcinogenesis of SCC.

Development of acetabulum and epiphysis of the femoral head following reduction in seventy-four patients with ninty-one congenitally dislocated hips were assessed radiologically. Acetabular index, CE angle of Wiberg, neck-shaft angle of the femur and overgrowth of the pelvis and femur were measured according to the various treatment. To evaluate results, the method of treatment was divided into four groups; closed reduction, open reduction, open reduction combined with pelvic osteotomy and modified Klisic operation (open reduction, pelvic osteotomy, femoral osteotomy and so on). Each treatment was compared with three subgroups according to ages; first subgroup was belong to patients under one year of age, second from one year to three years, third over three years. This paper agrees to Harris (1976) and Lindstrom (1979) about improvement of acetabular index and CE angle of Wiberg that showed a rapid rate of repair in the first 6 months and thereafter slowly progressed to normal range of degree. Overgrowth of pelvis and femur was also noticed in cases of hips treated pelvic and/or femoral osteotomy, moreover even in cases of open reduction only. The goal of this preliminary investigation may be supposed to propose the idea which method of treatment to the first visiting patient will approach the most satisfactory final result.

Choriocarcinoma is a relatively rare malignancy of which characteristic is rapid metastasis to the other organs. It is related to the previous gestation or originated from the teratoma. Choriocarcinoma is mostly originated from the intrauterine chorionic villi, but it is rarely originated from the utreine cervix, fallopian tube, ovary, vagina and pelvic cavity. Primary choriocarcinoma of the fallopian tube is exceedingly rare and it is originated from ectopic tubal pregnancy, tubal migration from the intrauterine pregnancy or intratubal teratoma. 9 Symptoms and signs of the choriocarcinoma originated from the ectopic pregnancy are abdominal pain, vaginal bleeding, palpable adnexal mass, positive pregnancy test and amenorrhea. Thus it is difficult to distinguish choriocarcinoma from ectopic pregnancy on the basis of symptoms before the microscopic diagnosis presented.20 Effective treatment of choriocarcinoma is chemotherapy. Additional operation is possible. B-HCG is a useful measure for the follow up. We experienced a 36-year-old multigravida Korean woman who was diagnosed as the rupture of ectopic pregnancy after left salpingectomy in our hospital and then confirmed primary choriocarcinoma of the fallopian tube without metastasis on microscopic finding. Postoperative chemotherapy was performed with methotrexate. The follow up of disease is still on going at two month intervals and she has remained healthy, We report this case with review of literatures.

Two patients, bulging fetal membrane accompanied with cervical dilatation & effacement in the late second-trimester, were treated by modified Shirodkar method. Pregnancies were prolonged effectively and viable fetuses were delivered in both cases. Our cases may help make objective decision prior to attempting cerclage placement when cervix is markedly dilated and something should be done to save pregnancy.

In order to evaluate the accuracy of endoscopic findings in the diagnosis of gastric can the endoscopic findings of gastric lesion were compared with the macroscopic and pathologic findings of excised identical lesion. 105 operated gastric cancer paitients (advanced cancer 95 cases, early cancer 10 cases) who were diagnosed endoscopically at Pusan National University Hospital from January 1983 to August 1987 were studied. The results were as follows; 1) The accuracy of endoscopic findings were 94.7% in the advanced gastric cancer, and 45.5% in the early gastric cancer. 2) The accuracy of gross findings endoscopic and pathologic in advanced gastric cancer were 50.0% in Borrmann type I, 45.0% in Borrmann type II, 73.2% in Borrmann type III, and 66.7% in Borrmann tyye IV. 3) The accuracy of the endoscopy ia morphologic classification of advanced gastric cancer according to pathologic tumor location were 60.0% in C (upper 1/3), 43.9% in M(middle 1/3),76.3% in A (lower 1/3), 55.6% in the anterior wall, 50.0% in the posterior wall, 66.7% in the greater curavature, and 67.2% in the lesser curvature. 4) The accuracy of endoacopy in morphologic classification of gastric cancer to tumor size ware 54.5% in below 2 cm, 54.5% in from 2.1 cm to 4 cm, 65.4% in from 4.1 cm to 6.0 cm, 80% in from 6.1 cm to 8 cm, 75.0% in above 8.1 cm. 5) The accuracy of endoscopy in the morphologic classification according to the pathologic tumor stage in advanced gastric cancer were 55.6% in TNM stage I, 52.0% in TNM stage II, 65.4% in TNM stage III, and 73,7% in TNM stage IV.

Atlanto-axial instability is an important condition that may threaten the integrity of spinal cord, leading to tetraplegia or sudden death. Many of these require operative stability, and several different operations have been advocated. Among these methods, Brooks and Jenkins posterior fusion for eleven cases of atlanto-axial instability (fresh fracture of odontoid process in nine, nonunion of odentoid fracture in one, Cl-2 rotary subluxation in one) was performed in Baik Hospital from July 1978 to June 1987, and the following results were obtained. l. Accurate reduction and immediate rigid stability were obtained with Brooks and Jenkins posterior fusion, so early ambulation with simple external support was begun within 2 weeks after operation. 2. Radiological fusion of atlanto-axial instability were seen in average 12 weeks after operation. Therefore posterior atlanto-axial fusion by Brooks and Jenkins method is an excellent method for operative treatment of atlanto-axial instability.
