1.A Study of Patch Test with Cosmetic Related Antigens in Patients with Contact Dermatitis.
Korean Journal of Dermatology 1984;22(2):187-190
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.

Thin-layer (uni-dimensional and bi-dimensional) chrornatography studies were performed on 60 brownish stockings from 12 companies in Korea to search for Disperse Yellow 3 and Disperse Orange 3, which are known as common sensitizers in textiles. The results were as follows : 1) Mixture of various-colored dyes were being used to reveal the brownish hue in the stockings. 2) TLC demonstrated the presence of Disperse Yellow 3 in 53 stocking. 3) TLC demonstrated the presence of Disperse Orange 3 in 3 stockings, Although lack or more sophisticsted tests such as spectroseopic, infra red or nuclear spectra identification. These results suggest a strong clue to the presence of Disperse Yellow 3 and Disperse Orange 3 in the commercial stocking now being used in Korea.

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.

Korean Journal of Dermatology 1984;22(4):427-430
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.

Alopecia areata is a relatively common disorded but the exact psthogenesis is still unknown and there is no satisfactory treatment. Recently contact immunotherapy has been studied with dinitrochlorogenzene(DNCB) which is known to have in vitro mutagenecity limiting its clinieal application. In contrast, diphencyprone (DPCP) is a potent contact sensitizing agent which is not known to be mutagenic. We treated 40 patients with alopecia areata who were refraetory to standard treatment.DPCP was dissolved in acetone in concentrations of 0.0001 2%. After sensitization, DPCP was topically applied to the right side of the scalp with left side sewing as control. After obvious hair growt,h, DPCP was applied on both sides of the scalp. A positive respanse was defined as growth of terminal hairs on the scalp. The response rate was estimated by determing the percentage of hair covered areas com- pared to the total area of the scalp. The results were as follows. 1) Of 20 patients who were followed over 3months, 9 patients(45% ) showed positive response, and 6 patients(30%) showed almost complete regrowth of terminal hairs (above 90% of scalp area). 2) The response time varied from 4 weeks to 33 weeks, with average duration of 10.6 weeks. 3) Nine out of forty patients developed side effects such as severe contact eczema, cervical lymph node swelling and vitiligo. Three out of 40 patients had to discontinue therapy due to side effects. 4) Patients with mild alopecia areata ganerslly showed a higher response rate(50%) than those with alopecis totalis(33%) and alopecia universalis(43%), but the differences were not statistically signifieant(p>0.05). 5) No correlation was found between reaponse rates and clinical factors such as age, sex and duration ot the disease. In conclusion, treatment with DPCP was thought to be effective in patients with alopecis areata who were refractory to standard treatment. Further long-term studies may be neees- sary to find out clinical course of the disease after trestment, and long-term safety of this treatment.

Demacre', a new topical steroid cream containing 0.025% beclomethasone dipropionate, was used in several kinds of dermatoses. Total 35 patients including ll cases of contact dermatitis, 5 of atopic dermatitis, 3 of hand eczema, 3 of seborrheic dermatitis, 2 of neurodermatitis, 2 of nummular eczema, 2 of autosensitization dermatitis, 1 of chronic eczema, 3 of psoriasis, 1 of insect bite, 1 of miliaria rubra, and 1 of intertrigo were treated by Demacre'. Among these patients, we observed excellent effects in 4 patients (11%), good effects in 22 patients (63%), and fair effects in 3 patients (9%). Namely, among these 35 patients, 26 patients (74%) revealed excellent to good therapeutic effects on their skin conditions with Demacre'. No untoward side effects were noted in all subjects treated with Demacre.

Korean Journal of Dermatology 1984;22(5):492-495
Formalin is a 37 5pg aqueous solution of formaldehyde gas and formaldehyde may be present in products as an active ingredient, preservative or contaminant. This contamination may be from the container, the package material or in situ formation by degradation of the formaldehyde releasers. The free formaldehyde content was determined in the 50 kinds of Korean shampoos by quantitative analysis recently described, the lutidine method, which is simple, rapid and used for colored products which cannot be analysed by the chrornotropic acid method. Formaldehyde has been found in 46 out of the 0 samples, i.e., 90g., and the concentration ranged from 0. 1 to 78. 6 pg/ml(0. 1 78. 6 ppm).

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.

BACKGROUND: Long-term oral itraconazole and terbinafine are widely used in the treatment of onychomycosis. Accelerated nail growth in patients with itraconazole has been described in several reports. However, there has been no report regarding the effect of antifungal agents on cultured nail matrix cells(NMCs). OBJECTIVE: We applied several antifungal agents on cultured human NMCs and epidermal kera- tinocytes(EKs) to compare the cytotoxicity of several antifungal agents and also to verify possible stimulating effects of itraconazole and 6-hydroxyitraconazole on nail growth. METHODS: To evaluate the effect of antifungal agents, the 3-(4,5-dimethylthiazo1-2-yl) 2,5-diphenyl- tetrazolium bromide(MTT) test, tritiated thymidine incorporation test, and lactic dehydrogenase(LDH) leakage test were used. RESULTS: Dose dependent decreases in cell viability and DNA synthesis, and dose dependent increases in LDH liberation were observed in cultured human NMCs and EKs after exposure to several antifungal agents. The dose-response reaction patterns for NMCs and EKs to antifungal agents were similar. The cytotoxicity potency of several antifungal agents measured by each method were slightly different. Itraconazole and 6-hydroxyitraconazole did not show stimulating effects on cell proliferation in in vitro monolayer cell culture systems. CONCLUSION: These observations suggest that itraconazole appeared less cytotoxic but showed no stimulating effects on nail matrix cell proliferation in vitro. Cultured human EKs as well as NMCs may be useful in evaluating the effects of agents which are involved in nails.
