PURPOSE: Radiation proctitis and radiation cystitis are frequent and problematic late complications in patients treated with radiation for the uterine cervix cancer. Authors tried to find out the better patient's position in high dose rate intracavitary radiation to reduce the radiation dose of bladder and rectum. MATERIALS AND METHODS: In 13 patients, Foley catheters were inserted to patients' bladder and rectum and were ballooned with radioopaque dye. After insertion of a tandem and two ovoids, semi-orthogonal anteroposterior and lateral films were taken in both lithotomy and supine position. The rectal point and bladder point were defined according to the criteria recommended in the ICRU Report 38 with modification. Using these films, all patients' bladder and rectal dose were calculated in both positions (the radiation dose of A point was set to 400 cGy). And also, the distance of bladder and rectum from uterine cervical os was calculated in both positions. RESULTS: The average radiation dose of rectum was 240.7 cGy in lithotomy position and 278.3 cGy in supine position, and the average radiation dose of bladder was 303.5 cGy in lithotomy position and 255.8 cGy in supine position. After the paired t-test, the radiation dose of rectum in lithotomy position was marginally significantly lower than that in supine position, while the radiation dose of bladder in lithotomy position was significantly higher than that in supine position. On the other hand, the average distance between rectum and cervical os was 35.2 mm in lithotomy position and 32.3 mm in supine position. and the average distance between bladder and cervical os was 30.4 mm in lithotomy position and 34.0 mm in supine posi-tion. After the paired t-test, the distance between rectum and cervical os in lithotomy position was significantly longer than that in supine position, while the distance between bladder and cervical os in lithotomy position was significantly shorter than that in supine position. CONCLUSION: The radiation dose of bladder can be reduced in supine position and the radiation dose of rectum can be reduced in lithotomy position, so we can choose appropriate position in each patient.

In view of ever rising water pollution problems of river in the vicinity of large urban communities, the author has made an investigation on the pollution of water sampled from Han River (Seoul area) and Nakdong River (Daegu city area) during the period from july to December, 1970. The water samples were taken twice a month during the study period of 6 months from 7 points (locations) along the main stream of Han River at Seoul city and 5 points of Nakdong River at Daegu city. The samples ware measured and analyzed in accordance with the recognized methods in the "Standard Methods or Examination of Water and waste" by American Public Health Association. The obtained results are as follows: I.Han River. 1.

B.O.D. in July and August (35.6 and 34.5 ppm.) were the highest and that in November and December (18.6 and 21.2 ppm.) were the lowest. 5. Suspended Solids (SS) were from 15.0 to 667.0 ppm. with the mean of 222.1 ppm "Suspended Solids" of the water samples at Yunchang-Dong and the 2nd Han River Bridge were found to be 378.1 ppm. and 283.9 ppm. respectively which were higher than at the Gwangzang Bridge (134.1ppm.) and at Walker Hill boating place (79.3ppm). 6. Coliform colonies counting of the water samples ranged from 0-2, 500x10/100ml. with the mean value of 205.6x10/100ml. The most contaminated water sample by coliform were from the point of the 2nd Han River Bridge with 640.8x10/100ml while the lowest ones were from Walker Hill boating place with 17.2x10/100ml. There was also a seasonal variation in coliform contamination that is the higher in summer and the lower in winter. II. Nakdong River. 1. The mean value of turbidity was 2.3 units with range of 0 to 9.0 units. The highest point was at Geumho River (7.2 units). and the lowest point was at Gangzung and Moonsan (0.45 and 0.41 units). 2. The mean value of pH was 7.5 (range of 7.1-8.5) and highest point was Geunho River with 8.5. 3. The mean value of D.O was 8.1ppm. (range of 3.4-11.2 ppm.). D.O. of the upper stream showed higher value than that of the down stream, and the winter season than the summer season. 4. B.O.D. ranged from 2.6 to 57.0 ppm. (mean; 20.4 ppm.). The water sample at Geumho River showed the highest value (41.5ppm) while at Moonsan and Gangzung showed the lowest (4.6 and 4.7 ppm.). 5. The mean value of suspended solids was 48.7 ppm. (range of 4.0-182.0 ppm.). The highest month was July (63.7 ppm.) and August (62.1 ppm.) and the lowest month was October (37.0 ppm.) and December (24.4 ppm.). 6. The mean value of the coliform colonies was 22.7x10/100ml. (range of 0-243x10/100ml.). The highest number of the colonies was found in the sample water at the Whawon recreation area (50.5x10/100ml.) followed by the Geumho River (33.9x10/100ml;), the Goryung Bridge (28.3x10/100ml.), Gangzung(0.7x10/100ml), and Moonsan (0.6x10/100ml.).

During the period from July 1st to the end of November 1970, a survey on air pollution and noise level was made in Seoul, Pusan and Taegu, the three largest cities in Korea. Each city was divided into 4-6 areas : the industrial area, the semi-industrial area, the commercial area, the residential area, the park area and the downtown area. Thirty eight sites were selected from each area. A. Method of Measurement : Dustfall was measured by the Deposit Gauge Method, sulfur oxides by PbO2 cylinder method, suspended particles by the Digital Dust Indicator, Sulfur dioxide (SO2) and Carbon Monoxide (CO) by the MSA & Kitakawa Detector and the noise levels by Rion Sound Survey meter. B. Results: 1. The mean value of dustfall in 3 cities was 30.42 ton/km2/month, ranging from 8.69 to 95.44. 2. The mean values of dustfall by city were 33.17 ton/km2/month in Seoul, 32.11 in Pusan and 25.97 in Taegu. 3. The mean values of dustfall showed a trend of decreasing order of semi-industrial area, downtown area, industrial area, commercial area, residential area, and park area. 4. The mean value of dustfall in Seoul by area were 52.32 ton/km2/month in downtown, 50.54 in semi-industrial area, 40.37 in industrial area, 24,19 in commercial area, 16.25 in park area and 15.39 in residential area in order of concentration. 5. The mean values of dustfall in Pusan by area were 48.27 ton/km2/month in semi-industrial area, 36.68 in industrial area 25.31 in commercial area, and 18.19 in residential area. 6. The mean values of dustfall in Taegu by area were 36.46 ton/km2/month in downtown area, 33.52 in industrial area, 20.37 in commercial area and 13.55 in residential area. 7. The mean values of sulfur oxides in 3 cities were 1.52mg SO3/day/100cm2 PbO2, ranging from 0.32 to 4.72. 8. The mean values of sulfur oxides by city were 1.89mg SO3/day/100cm2 PbO2, in Pusan, 1.64 in Seoul and 1.21 in Taegu. 9. The mean values of sulfur oxides by area in 3 cities were 2.16mg SO3/day/100cm2 PbO2 in industrial area, 1.69 in semi-industrial area, 1.50 in commercial area, 1.48 in downtown area, 1.32 in residential area and 0.94 in the park area, respectively. 10. The monthly mean values of sulfur oxides contents showed a steady increase from July reaching a park in November. 11. The mean values of suspended particles was 2.89mg/m3, ranging from 1.15 to 5.27. 12. The mean values of suspended particles by sity were 3.14mg/m3 in Seoul, 2.79 in Taegu and 2.25 in Pusan. 13. The mean values of noise level in 3 cities was 71.3 phon, ranging from 49 to 99 phon. 14. The mean values of noise level by city were 73 phon in Seoul, 72 in Pusan and 69 in Taegu in that order. 15. The mean values of noise level by area in 3 cities showed a decrease in the order of the downtown area, commercial area, industrial area and semi-industrial area, park area and residental area. 16. The mean values of noise level by area in 3 cities indicated that the highest level was detected in the downtown area in Seoul and Taegu and in the industrial area in Pusan. 17. The daily average concentration o sulfur dioxides (SO2) in 3 cities was 0.081 ppm, ranging from 0.004 to 0.196. 18. The daily average concentration of sulfur dioxides by city were 0.092 ppm in Seoul, 0.089 in Pusan and 0.062 in Taegu in that order. 19. the weekly average concentration of carbon monoxides (CO) was 27.59 ppm. 20. The daily average concentration of carbon monoxides by city were 33.37 ppm. in Seoul, 25.76 in Pusan and 23.65 in Taegu in that order. 21. The concentration of SO2 and CO reaches a peak from 6 p.m. to 8 p.m. 22. About 3 times probably the daily average concentration of CO could be detected in the downtown area probably due to heavy traffic emission in comparison with that in the industrial area. 23. As for daily variation of the concentration of SO2 and CO it was found that the concentration maintains relatively higher value during weekdays in the industrial area and on the first part of the week in the downtown area.

Pure fetal blood was obtained by cordocentesis or cardiocentesis guided by USG in 160 fetuses at 15 to 37 weeks' gestation. Only 1 case failed to obtain cytogenetic result. Cytogenetic analysis of fetal lymphocytes yielded results within 5 days. Chromosomal abnormalities were found in 21 of 159 fetuses(13.2%). Abnormal karyotypes were found in 19 of 118 fetuses(16.1%) with structural malformations~8.6%(7/81) affected by isolated malformations vs. 32.4%(12/37) affected by multiple malformations. There were 12 cases of bradycardia which was the most common nonfatal complication (7.4%). One fetal death was recorded. Pregnancy outcome is as follows: 17 cases of stillbirth, 38 cases of termination of pregnancy, 15 cases of neonatal death, 5 cases of infantile death, 55 cases of living babies, and 29 cases lost to follow-up. It is concluded that rapid karyotyping by cordocentesis is advisable as effective method in fetuses at high risk of a chromosomal aberration, especially in advanced gestations.

PURPOSE: To compare clinical, angiographic, and optical coherence tomographic characteristics between eyes with acute Vogt-Koyanagi-Harada (VKH) disease and eyes with acute bilateral central serous chorioretinopathy (CSC), and to demonstrate distinguishing features between the two diseases in confusing cases. METHODS: The medical records of 35 patients with VKH disease and 25 patients with bilateral CSC were retrospectively reviewed. Characteristics according to slit-lamp biomicroscopy, ophthalmoscopy, fundus photography, fluorescein angiography, indocyanine green angiography, and spectral-domain optical coherence tomography were compared between the two diseases. RESULTS: Five of 35 patients (10 of 70 eyes, 14.3%) with VKH disease were initially misdiagnosed as CSC patients, and six of 25 patients (12 of 50 eyes, 24%) with bilateral CSC were initially misdiagnosed as patients with VKH disease. Pigment epithelial detachment in CSC and optic disc hyperemia in VKH disease show the highest positive predictive values of 100% for each disease. CONCLUSIONS: Optic disc hyperemia in VKH disease and pigment epithelial detachment in bilateral CSC are the most specific clinical manifestations of each disease at initial patient presentation.

In patients with inflammatory bowel disease (IBD), cytomegalovirus (CMV) infections could aggravate the course of IBD but it is difficult to distinguish CMV infection from IBD exacerbation endoscopically. Usually, CMV tends to localize to the colon and other organic involvements were reported very rare in the IBD patients. Herein, we report a case that CMV gastric ulcer complicated with pyloric obstruction in a patient with ulcerative colitis during ganciclovir therapy, which was resolved by surgical gastrojejunostomy with review of literature.

PURPOSE: To report the first case of pigmented choroidal metastases without enucleation diagnosed with fine-needle aspiration biopsy. CASE SUMMARY: A 47-year-old male was referred to our clinic with a suspected diagnosis of choroidal melanoma in his left eye. Positron emission tomography-computer tomography used to evaluate systemic metastases revealed lung cancer. Pathology of the detected lung mass was primary lung neuroendocrine tumor. To differentiate choroidal metastasis and primary choroidal melanoma, we performed a fine-needle aspiration biopsy for choroidal tumors. The cytology showed results favoring metastatic atypical carcinoid and the patient was started on systemic chemotherapy. CONCLUSIONS: All pigmented choroidal tumors are not choroidal melanomas and choroidal metastases may be pigmented. The present case suggests that proper systemic evaluation and biopsy for suspected choroidal tumor could be helpful in diagnosis.

We report a case of ganglioneurocytoma manifesting as a complex partial seizure in a young adult male. MR images depicted a well-marginated cystic mass with a heterogeneous solid portion abutting the dura in the parietal lobe. The solid portion showed minimal heterogeneous enhancement, and pressure erosion of the overlying calvarium had occurred. Following gross total resection, the clinical outcome was satisfactory, with no further seizures, and during the five-year follow-up period, the tumor did not recur.
