The ovarian specimens obtained from the patients with 27 malignant germ cell tumors were analyzed in order to study DNA and form factor using flow cytometry and image analyzer. The malignant germ cell tumors consisted of six dysgerminomas, six endodermal sinus tumors, seven immature teratomas, three teratomas associated with squamous cell carcinoma, two embryonal carcinomas one mixed germ cell tumor and one malignant struma ovarii. Five normal ovaries used as control group. Various prognostic factors such as DNA ploidy, S-Phase and measurements of from were evaluated by flow cytometry and image analyzer. Mitotic index, histological grade, nuclear grade and tumor necrosis were assessed with microscope. These prognostic factors of DNA ploidy, S-phase, form factor histological were compared with tumor recurrence and clinical stage in this study. The results were as follows: 1. Sixteen(59%) out of 27 were aneuploidy and 11(41%) diploidy. All six dysgerminomas and six endodermal sinus tumors were aneuploidy, while six immature teratomas were diploidy. 2. S-phase fractions of malignant germ cell related significantly with those mitotic index(P=0.0201). S-phase fractions significantly increased in mitotic index gradeIII compared with grade I(P<0.01). There was no significant different between grade Iand II, and between gradeII and III. There was no difference between S-phase fractions and the remaining histological variables. 3. The incidence of aneuploidy was higher in the high s_ phase fractions(P=0.0041). However, there was no difference between S-phase fractions and tumor recurrence. 4. The incidence of aneuploidy significantly increased in clinical stage III and IV compared with stage I and II(P=0.0368). However, the difference between clinical stage histological variables was not significant. 5. The difference between form factor and histological variables, between from and tumor recurrence(P=0.3698), and between from factor and S-phase fractions(r=0.76) could not reach statistical significance. These results suggest that ploidy can give significant value for routine clinical prognostic prediction, whereas hitologic variables and form factor are poorly suitable for the prognostic evaluation.

Numerous studies on epidemiological aspects of contact dermatitis have been published in recent years since the introduction of a standardized method of patch test. We have performed the patch test on patients with contact dermatitis and on patients with other forms of dermatitis, A total of 153 patients were tested in this study between January 198l and August 1982. We have routinely attached 29 Hollister's standard batteries and 0. l% Tego, which is a commonly used antiseptic in our hospital, to the patients back. The tapes used were Leukotape and Finn chamber. Forty-eight hours after the tape had been attached, the patches were removed and read. The second reading was taken 24 or 48 hours after the patch had been removed. According to the results of this study, the most common allergens were cinnamic alcohol (11. 1%), ammoniated mercuric chloride (10. 5%), nickel sulfate (9. 2%), hydroxycitronellal(6. 5%), paraben mix(5. 9%), mercaptobenzothiazole(5. 9%) and thimerosal(5. 9%). In conclusion, cosmetics, metals, medicaments and rubber compounds were found to be the most common etiologic agents of contact dermatitis in this studyBackground and possible explanation of these rusults were discussed and a comparison was made between this report and others.

This study was undertaken to investigate the response of non-immunologic contact urticaria(NICU) test before and after ingestion of cyclo-oxygenase inhibitors such as naproxene, ibuprofen and mefenamic acid. Forty patients who showed positive reaction to 5% benzoic acid (BA) in petrolatum by 20 minutes closed patch test were chosen and divided into 3 groups. Group I was consisted of 13 patients who were taken naproxene 250mg bid, group II, 14 patients, taken ibuprofen 600mg bid, and group III, 13 patients, taken mefenamic acid 500mg bid. All the patients were tested with 5%, 2.5%, 1%, 0.5% and 0.1% BA in petrolatum using Finn chamber on Scanpor tape on the right arm before medication and next day on the left arm after medication of each day. Mefenamic acid did not show any significant differences before and after ingestion of drug. Naproxene reduced reaction about half of patients. Ibuprofen reduced reaction in almost all patients and blocked reaction completely in 9 of 13 patients. This results suggested that there was no correlation between blocking effect to BA induced contact urticaria and so called anti-inflammatory potencies of naproxene and ibuprofen, and that NICU by BA is partly mediated by prostaglandins(PG) or mediated by other mediators, which were potentiated by PG, except histamin.

Quaternium-15 (Dowicil 200) which is a water-soluble antimicrobial agent and a formaldehyde releaser is widely being used as a preservative in cosmetics and medicaments these days. However, there are scanty reports about it in the Korean literature. Recently, we have experienced two cases of Quaternium-15 contact dermatitis probably related with their cosmetics and topical medicament, respectively. We report our cases with the patch test results.

Favre-Racouchot syndrome(nodular elastosis with cysts and comedones) is a peculiar complication of solar elastosis in which comedones, follicular cysts, and nodules of altered elastic tissue occur mainly sround the orbits, on the cheeks, on snd around the nose, and oceasionally in other exposed areas, but sornetimes on the neck or behind the ears. We present a typical case of the Favre-Racouchot syndrome in a 66 year old man with maxillary cancer. The patient had numerous yellowish cysts and black topped comedones located on the forehead, around the orbits and the nose, on the neck, and also behind the ears of 5 years duration. The histopathology of the lesion showed dilated pilosebaceous openings and epitheliaI lined cysts filled with layered keratin in addition to pronounced solar elastosis.

Sebaceous carcinoma of the eyelids is rare and is usually seen in the elderly persons. The meibomian glands of the tarsus are the frequent sites of origin. The characteristic feature is a firm, painless nodule on the upper eyelid, We present a typical case of the sebaceous carcinoma in 60 year-old female. The patient had 1 * 1cm sized, hard, fixed, non-tender mass with bleeding on the right lateral canthus of 3~4 months duration. The histopathology of the lesion showed irregular sized lobules in the dermis with invasive growth to the surrounding stroma. Many fat containing sebaceous celles are seen in the center of the lobules.

Accessory auricle is a relatively rare congenital anomaly arised from the abnormaI development of the auricular tubercles or from the tissues surrounding the second, third and fourth branchial clefts. Clinically this anomaly is a small akin-colored tag or nodule, soft and globular or cartilaginous consistency on or near the tragus along a line drawn from the tragus to the angle of the mouth or along the anterior margin of the sternomastoid muscle. The lesion is usually solitary and located in the preauricular area but may be multiple and rarely bilateral. We present a typical caae of accessory auricles in 4-day-old female infant. The patient had two skin-colored firm nodules on the left preauricular area and well pedunculated one on the Ieft buccal area near the angle of the rnouth. Histopathologic find.ings showed numerous pilosebaceous units, abundant subcutaneous fat and cartilage tissue in the center of the lesion.

PURPOSE: This project was designed to study the effectiveness and safety of Dream lens(TM) (OK B+ series lenses, Contex, USA) in correcting myopia in a population of school children, under 13 years old. METHODS: Twenty-three school children aged 7 to 13 years followed over a 3-month period were fitted with lenses in the Vision Eye Center from September 2002 to March 2003. Slit lamp examination, uncorrected visual acuity, autorefraction and autokeratometry by Canon RK-5 and topography were measured at baseline and at 1week, 1 month, and 3 months after the lenses were worn. RESULTS: The mean baseline autorefraction was -2.54 +/- 1.00 diopters (range: -0.63~-4.00) and baseline uncorrected visual acuity over 0.5 was 11.1% and over 0.8 was 0%. Vision correction of over 0.8 was found in 80% of the cases in the first 1 week, 78% at 1 month, 91% at 3 months with the most rapid improvement occurring during the first 1 week. Superficial punctate keratitis occurred in 4 of 45 eyes, but there was no other pathologic problem. CONCLUSIONS: Dream lens is an effective and safe means of temporarily reducing myopia in a certain range of myopic patients; however, further studies are needed to determine the long-term effects on the eye health.
