A Case of Retroperitoneal Teratoma / 대한비뇨기과학회지

Retroperitoneal teratoma is a rare tumor composed of tissues from all three germ cell layers - endoderm, mesoderm, ectoderm. It is generally known as a disease of baby or children and as 10% of retroperitoneal tumor. Recently, we experienced a case of retroperitoneal teratoma in adult.

A Study on the Intraocular Pressure of Koreans Part 1: The Intraocular Pressure(I.O.P.) of 405 Normal Koreans

The normal intraocular pressure which are known to us are the standards of ocular pressure obtained by testing foreigners. According to the reports, the scope of normal I.O.P. is 15-25 mmHg. However, in the case of our neighboring Japanese the scope of normal I.O.P. is 10-15 mmHg and its average is 18.11 mmHg by Schiotz's tonometer. In order to study the I.O.P. of Korean, the writers of this report have tested 405 normal persons(810 eyes) and herewith report the results obtained from the tests. Conclusion: 1. The I.O.P. of 405 normal Koreans is as follows. Reliability range: 12-19 mmHg, Average Value: 15.5 mmHg. 2. As for the diurnal variation, the minimum mean of 10.8 mmHg was found at 1.00 P.M. and the maximum mean of 16.5 mmHg was found at 7.00 A.M. the standard error in each was 0.28 and 0.50 respectively and its difference was 4.5. 3. No difference was found by age or sex.

Retinal hemorrhage in the newborn, a statistical study of 648 infants

here is a wide variation in the incidence of retinal hemorrhage in the new born. Koenigstein reports the occurence rate as 10% Sylvan as 27%, Haessler as 33% and Corburn as 46%. Thus the reported incidence of retinal hemorrhage in the newborn varies from 10 to about 40%. Also, there is no general agreement as to the cause of the retinal hemorrhage. Intensive studies of this condition in the newborn have been carried out in several countries. However, there have been no reports of such studies in the Korean newborn. Such a clinical investigation and research program was recently undertaken at the Ewha Woman's University Hospital. 648 infants were examined for the presence or absence of retinal hemorrhage within 24-48 hours of the time of birth. Delivery had been by the normal method, by forceps delivery by breech delivery or by cesarean section. In order to dilate the pupils, we instilled 1% Homatropine into each eye three times. This was done at three minute intervals about 20 minutes before the examination. The retina was examined directly with the infant in complete darkness. After the examination, 1% pilocarpine nitrate solution was instilled into the babys eyes. The results of our clinical research include the following findings: 1. 155 out of 648 newborns were found to have retinal hemorrhage, as incidence of 23.9%. 2. The incidence of hemorrhage was greater in the male(27.9% in male, 19.4% in female). 3. The incidence of hemorrhage in the infant of the primipara was 3.8% greater than that of the multipara. However, statistically speaking, the chi-square test showed no significant difference between the two groups. 4. Premature infants(weight less than 3 ilograms) and post- mature infants(weight more than 3.6 Kilograms) showed a greater incidence of retinal hemorrhage than that found in infants of normal weight(18 tables).
