Contact Dermatitis due to cosmetics is also common in Korea. as in other developed countries. However. detection of the causative antigens is in a difficult situation due to many reasons. We have routinely patch tested with Japanese cosmetic series patch test allergens, Types 17 and 18 in addition to Hollister standard battery and patients own cosmetics to 4Q cases of suspected cosmetic contact dermatitis who have visited our Environmental and Occupational Clinic during the past one year. The study result was as follows. Total 55% ositive reaction related to cosmetics was observed in 4p patch tested patients. 2 The most frequently observed antigens were hydroxycitronellal, benzyl saliylate and cinnamic alcohol.

The ability of nicotinic acid and its substitutes to increase cutaneous blood flow has been measured by laser Doppler flowmeter in 30 healthy human volunteers. We applied nicotinarnide, nicotinic acid ethyl ester, nicotinic acid methyl ester, hexyl nicozinate each in an acqeous solution at a concentration of 10 mM/liter for 10 minutes occlusion on the forearm. The change of blood flow was serially checked at 5 to 10 minutes intervals for one hour. The study results were as follows : l. The relative maximum cutaneous blood flow response was in following order nicotinic acid methyl ester(100%), nicotinic acid ethyl ester(98%), hexyl nicotinate (84%) and nicotinic acid(63%). However, there was no statistically significant difference(p>0.05) between each drug. There was statististically significant difference between nicotinamide and all other nicotinic acid substitutes(p<0.05). 2. The time required to reach maximum blood flow response was 6.7 minutes for hexyl nicotinste, 10 minutes for nicotinic acid ethyl ester, 12.5 minutes for nicotinic acid methyl ester and 20 minutes for nicotinic acid. However, there was statistically significant difference between hexyl nicotinate and nicotinic acid only(p<0.05). 3. Significant decrease of cutaneous blood flow was observed one hour after the removal of the patches in all drugs.

Recently, people living in a rapidly industrializing country such as Korea seems to have less opportunity to be exposed to Rhus and Ginkgo trees than before, which may cause a lower prevalence of sensitivity to such allergens than those reported in the past. To prove the prevalence of sensitivity in Koreans, we have tested 0. 002g and 0.0l%, Urushiols and 10% Ginkgo leaves produced by Torii company to 72 atients with or suggesting contact dermatitis. The results were as follows: 1) Twelve of 72 patients(13, 9%) showed positive reactions and two patients(2. 8 %) showed active sensitization to both 0. 002% and 0. 0l% Urushiols. Only one patient(]. 4%) reacted to 10g Ginkgo leaves, and she was also reacted to the Urushiols. 2) Age and sex distribution of the positive reactors were none under thirty, 2 in thirties, 3 in forties, 4 in fifties, one over sixty, and seven female patients outnumber three male patients. 3) Out of 5 patients having past history cf contact dermatitis to Rhus tree, only patients showed positive reactions. Out of 67 patients without past history of allergy to Rhus, 8(ll, 9%) showed positive reactions and 59(88. 1%) showed negative reactions.

Resorcin is widely being used in the fields of the therapeutics, cosmetics, industry, but allergic contact dermatitis is an infrequent adverse reaction. We have experienced a case of allergic contact dermatitis to resorcin. A 59-year-old male with Kaposi's sarcoma on the right foot developed linear erythematous vesicular eruption along the marking areas 4 days after application of Castellanis paint, used as a skin marking solution for radiation therapy. He showed patch test positive reaction to Castellani's paint as well as its individual components, resorcin and phenol.

Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu disease) is a familial disease that is characterized by delicate, ectatic vessels in the skin, mucous membrane and viscera. These patients have a generalized vascular derangement including pulmonary A-V fistula and angiomatosis. Episodes of hemorrhage in cornbination with a familial history and cutaneous telangiectasia are diagnostic. We preaented a typical case of hereditary hemorrhagic telangieetasia in a 3-year-old female who had. two episodes of hemoptysis and compatible telangiectatic skin lesion. Her pulmonary and hepatic angiornas were also proved by pulmonary and aortic angiography.

This study was undertaken to observe the difference of patch test and prick test positive reactions in three groups, 20 atopic dermatitis patients, 20 chronic urticaria patients, and 20 normal controls, Twenty commercial antigens (ToriiCo.) and twenty three frozen and boiled antigens of fishes and shellfishes were used as test materials. The results were as follows: 1. No positive reaction was observed in all sixty subjects in patch test. 2 In prick test, difference in reactivity was observed among atopic dermatitis (14. 7%), chronic urticaria (8.7%), and normal control(1. 5%) 3. There was significant difference in reactivity between Torii and frozen antigens in atopic dermatitis group, but no significance in chronic urticaria and control groups. 4. Boiling altered the reactivity in tested materials in all three groups of subjects singificantly. 5. Patients with past or family history of allergic diseases showed double fold higher reactivity tban patients without any history.

The pinch graft is one type of skin graft and is indicated in small, chronic stubborn wounds or ulcers where cosmetic results are not paramount. It is a common procedure for the rapid healing of leg ulcers in countries where these are very common, such as in western society. However, it is an unfamiliar procedure to dermatologists in Korea where leg ulcers are quite rare. We treated a case of leg ulcer in systemic sclerosis using pinch grafts with satisfactory results. The pinch graft may be a useful treatment method for skin ulcers in dermatologic surgery under adverse conditions.

Nickel is widely known as a common source of contact dermatitis and nickel sensitivity amounts to nearly 10 percent of allergic contact dermatitis patients. Common sources of nickel dermatitis are well known as necklaces, watches, rings, hooks, earrings and spectacle frames. Recently, we have seen five cases of nickel dermatitis the suspected sources of which were metal spectacle frames. The interim patch test result in our occupational and environmental clinic suggests that the metal spectacle frame is one of the most common sources of nickel dermatitis. Out of 84 medical students 27 wore metal spectacle frames. We have done a dimethylglyoxime spot test to the metal spectacle frames and got a positive result in 12 out of 27(44.4%). We conclude that metal spectacle frame seems to be one of the dominant causes of nickel dermatitis and it will be an increasing problem in our society.

This study was undertaken to elucidate extracutaneous hyperpigmentation of nevus of Ota by analyzing the 70 patients who visited Cryosurgery Clinic in Seoul National University Hospital between January 1984 and March 1985 This results were as follows: 1. The age of onset showed two peaks: the first one was at birth or soon after birth; 27 cases(38. 6%) and the second une was between 11 and 17 years; 37 cases (45. 7%). 2 Seventy cases were classified by Taninos method: 15.7% was type I a, 27. l% type I b, 28. 6% type Il, 20. O% type g and 8. 6% type IV 3.Fifty two out of 70 cases who were examined at the department of ophtha1rnology: pigrnentation of sclera was observed in 29 cases(55. 8%.), of conjunctiva in 18 cases(34.6%), of uveal tract in 14 cases(26. 9A), of fundus in 14 cases (26. 9%) and of optic papilla in 2 cases(3. 8%). 4 Fifty two out of 70 cases who were examined at the department of Otorhinolaryngology. pigmentation of tympanum was observed in ]0 cases(23, 8%,), of nasal mucosa in 6 cases(14. 3p,), of oral mucosa in 5 cases(11, 9%), of external auditory canal in 4 cases(9 5%) and of pharynx in 1 case(2.4%,)

54-year-old male patient with acute lymphocytic leukemia was consulted to our department. He had had a few painful erythematous necrotic plaques on the chest, which suggested initslly vasculitis or pyoderma. On histological examination, characterisitic histological findings of non-septated large hyphae were observed in the dermis and subcutaneoustissue, Although organism was not isolated on Sabouraud agar media containing cycloheximide, the diagnosis of cutaneous mucormycosis was made by the characteristic histological nattlre. He died after 2 weeks with amphotericin B intravenous injections so that additional fungus culture was not performed.
