OBJECTIVE: The purpose of this project was to suggest guidelines for management of Low grade Squamous Intraepithelial Lesion(LSIL) by evaluating natural course of LSIL of the uterine cervix. MATERIAL & METHODS: Among the women who visited Korea University Kuro Hospital from Jan. 1993 to Oct. 1998, One hundred fifty eight patients who were diagnosed as LSIL with colposcopy directed biopsy were followed up by colposcopy and/or cytology, HPV DNA test every 3 months. RESULT: In I58 patients who were diagnosed as LSIL, colposcopic examination confirmed progression to high grade intraepithelial lesion(HSIL) in 17(10.7%) patients, persistence of LSIL in 87(55%) patients, regression to normal in 54(34.2%) patients during the 3 year follow-up period. In prediction of LSIL subgroup, abnormal Pap test is 39%, 64%, 71% and abnormal HPV test is l6%, 29%, 65% in regression, persistent and progression group respectively. The shortest time of transition from minor lesion(LSIL) to high grade lesion was 12 months (the range, 12-51). CONCLUSION: Of the patients who were diagnosed as LSIL and monitored by colposcopy for 60 months, 34% had disease that regressed, 55% had persistent disease, and 11% had progressive disease. HPV DNA test(p=0.002) is more informative than pap test(p=0.567) in prediction of disease progression.

OBJECTIVES: Early diagnosis of intrauterine growth retardation is important to ensure optimal monitoring and delivery with the introduction of real-time and Doppler ultrasound systems, a noninvasive method of measuring human fetal blood flow has become available. The aim of this study is to compare blood flow velocity waveforms at the fetal descending aorta and umbilical artery in normal and in patients with pregnancy induced hypertension. METHODS: Using a combination of linear array real-time and pulsed Doppler ultrasound, blood flow velocity measurements were carried out at the fetal descending aorta and umbilical artery in 35 normal pregnancies and 18 cases of pregnancy induced hypertensive patients. RESULTS: The mean systolic/diastolic ratio of umbilical artery and aorta was significantly higher in PIH patients than in normal pregnancies(3.8 +/- 0.81 versus 2.97 +/- 0.52, p<0.05) and to predict perinatal morbidity, umbilical velocimetry is more sensitive than that of descending thoracic aorta. CONCLUSION: This study suggests that umbilical artery velocimetry could be used as a marker to predict adverse perinatal outcome.

To identify significant prognostic factors in patients undergoing simple hysterectomy in the presence of invasive cervical cancer, the records of 45 patients who had taken such a procedure between 1993 and 1997 were reviewed. Overall relapse-free survival and 5-year survival rates were 91.1 and 92.1%, respectively. Factors found to be significantly related to survival were the retrospectively determined stage(p=0.0000), the presence of residual disease(p=0.0001), and cell type(p=0.0000). By multivariate analysis, factor emerging as significantly detrimental to survival was the cell type. The presence of residual disease was a marginally significant factor(p=0.067). The expectations for survival of patients with residual tumor mass and/or with adenocarcinoma after simple hysterectomy appear to be markedly worse than those with others, so radical reoperation should be considered in those patients.

The author observed a case of retinitis punctata albescens who showed typical fundus findings with numerous, diffusely scattered whitish dots in the whole fundus, sparing the macular area. Under ordinary illumination, the peripheral visual field contracted concentrically from 20 to 50 degrees. There were also slight degree of reduction of central visual acuity, raised thresholds in dark adaptation and red-green color deficiencies.

OBJECTIVE: The purpose of this article is to report mixed germ cell tumor, which revealed changes compatible with early transformation of dysgerminoma to endodermal sinus tumor(EST) through histogenetic considerations and immunohistochemical stains. METHODS: Ovarian germ cell tumors were reviewed from files of Dept. Ob/Gyn. Seoul Paik Hospital fiom 1992.1 to 1996.12. Total of 5 cases include 4 pure dysgerminoma and 1 mixed germ cell tumars. All tissues were fixed in 10% neutral buffered formalin and embedded in paraffin and reviewed by two pathologists with immunohistochemical staining for cytokeratin, vimentin, AFP, PCNA, p53 & bc1-2. RESULTS: Grossly, the areas of transformation were located at the middle of the mixed tumor. The outer layer of the tumor mass was filled with typical pure dysgerminoma. They were characterised as the presence of microcysts and small glandular structures in hematoxylin-eosin(H-E) stains with positive stain for vimentin, except the tissue of the EST. The cells in the intermediate layer were characterised as the mixed form of dysgerminomatous and EST structures in H-E stains. AFP in the dysgerminomatous cells in intermediate layer and EST were stained, but not in outer layer. CONCLUSION: Dysgerminoma may possess the ability to transform to EST. There might be intermediate stage between dysgerminoma and EST, and Immunohistochemical staining for AFP, cytokeratin, vimentin, PCNA also can be used for prognosis of germ cell tumor.
