Background : Hydrofluoric acid(HF) is one of the strong stirritating, corrosive and poisonous inorganic acid, The HF burns are occuring with ever-increa firifrequency due to the wide use of this acid in industrial fields, such as electronics and semicor tor industries. Objective : The purpie of this study is to quantiate theound depths produced by varying concentrations of HF aiud to suggest the treatment guideline. Methods : Uarious cinicentrations of HF(5%, 25%, 50%),were applied to two pairs of test sites on a guinea pig's back in a uniform fashion with cotton-tip applicators and then the histopathologic changes of guinea pig skin were observed. Results : 1, In the 5% HF applied group, intracellular edema vaobserved in the epidermis after 12 hours. After 3days, epidermal cell necrosis was observed. 2. In the 25% HF applied group, intraepidermal vesice was observed after 6hours. After 12hours, inflammatory cell infiltrations were observed in the apper dermis and then after 3days, dermal necrosis was oberved. 3. In the 50% HF applied group, epidermal cell necros After 6hours, liquefaction degeneration in the epidermis an was observed focally after 3hours. iflhmmatory cell infiltrations in the upper dermis were observed. After 2days, dermalar.ecrosis was observed and then after days, the reaction was at its peak and subcutaneous tissuc. necrosis was observed. Conclusion : This study showed that a higher concentrator HF exposure enhances The penetration of HF. For treatmi not alcohloic solution of a quarternary ammonium for avintralesional injection of calcium gluconate within 24 hours of HF and a longer period after we suggest wet dressing with an concentration of HF burn and high concentration of HF burn.

Hyperkeratosis of the nipple and areola is a rare skin disordr characterized clinically by thickening and discoloration of the skin of the areola and/or nipple and pathoiog cally by papillomaosis or acanthosis-nigricans like changes. We report a case of hyperkeratosis of the nipple and areola occuring in a woman with no underlying endocrinopathy and no other additional hyperkeratotic conditions. Ttie iresent case seems to be the nevoid form by the Levy-Franckel classification. Treatment with topical medications including steroids and keratolytic agents produced no improvement. Therefore we recommeneded surgical excision because the paient was greatly disturbed by the appearance of the lesions. Surgical excision and full thickness skin graft were performed sucessfully.

Background: Occupational dermatoses are increasing tendency in Korea. But there were only a few reports about occupational dermatoses in Korean dermatologic literatures. Object: For the effective preventive method and having interest in occupational dermatoses, we have done wide ranged basic study about the occupational dermatoses for 3 years in a semiconductor industry. Methods: The number of workers of the semiconductor industry was 10,500(male 5,000, female 5,500) and finally the number of analysed patients in this survey was 2,736. A dermatologist attended regularly at the clinic in a semiconductor industry once a week for the duration of 3 years from June 1992 to May 1995. Diagnosis was made by clinical findings and investigation about the working environment. Results: 1. The most common dermatoses are contact dermatitis(14.3%), acne(14.0%), seborrheic dermatitis(7.1%) and tinea pedis(6.9%). Urticaria, hand eczerna, abscess, onychomycosis, t.inea versicol or and chemical burn were also observed frequently. 2. Chemical burn(2.0%), contact dermatitis(1.4%) and acne(0.8%) were the most important occupation related dermatoses in this survey. Hydrofluoric acid(1.4%) was the main cause of chemical burn. The occupationa contact dermatitis and acne in this survey were mainly came from the mask, hood and dust preventing clothes which the workers must wear for 8 hours a day at working place. 3. The other dermatoses related to occupation were hand eczema, trauma, nummular eczema, atopic dermatitis, etc.. Conclusion: This study regardless of insufficient inspection equipment was done for a relatively long period in the semiconductor industry. In the future, many studies like this will be reported and the studies will give a model of management of occupational dermatoses in Korea. (Kor J Dermatol 1996;34(4): 622-628)

Background : Hydrofluoric acid burns are occuring with ever-increiisir g frequency due to the wide use of this acid in industrial fields, such as electronics and semiconductor i idustries. Objective : The purpose of thie study was to evaluate the clinical charateristics of hydrofluoric acid burn. This study will give basic information of hydrofluoric acid burn to the dermatologists who are not familiar with hydrofluoric acid. Method : Twenty-two patient who were diagnosed as having hydroiluiiric acid burns at koryo General Hospital(1986-1993) were irraluated clinical)y. Forteen were malc ar d eight were female, most of them were in their third decade. Results : The results are sumrnurised as follows 1. Latent periods were variabie from 30 min. to 3 days. Most patients recognized their chemical burn several hours after exposure. 2. Foot & sole (9 cases) and fingers (7 cases) were most frequently in olved. In 7 cases, nails were also involved. 3. Pain was the most. commori iuobjective symptom. 4. Skin lesions showed erytherna, erythematous swelling, erosion, bulla., necrosis, pigmentation and crust, formation, progressii ely. 5. Treatment Wet dressing with Hyami-solution and topical application of ai tibiotics or steroidointment were sufficient in mild case. In severe cases, intralesional injection of calcium glucoante was perfirmed. Debridement was also performed after the progn ssion of tissue damage stopped. Nails were extracted in cases involving nails. Conclusion : Hydrofluoric acid burn is characterized clinically by severc progessive tissue destruction and excruciating pain. Dermatologists need to be aware of the clinical features of hydroclucric acid burn and its proper treatment. (Kor J Dermatol 1993,;31(5):672-680)

Recently radiation and radioisotope are being used widely in many fields such as medicine and industry. But only a few papers were reported about the radio dermatitis due to industrial use of radiation. Authors experienced 4 cases of occupational radiodermatitis due to Ir-192 occur red during the radioisotope traspierce test. All 4 patients noticed painful swelling, erythema, and bullae on their fingers or palms 1-2 weeks after exposure. All laboratory tests to detect ystemic effects of radiation were normal. Three patients recovered after treatment with systemic and topical corticosteroid and emollient cream for 2-4 weeks. But one patient suffered from complication of fibrosis and recurrent cellulitis on his fingers. We discussed about the working situation of our patients and reviewed the literatures about the radiodermatitis.

The importance of garlic as a cause of hand eczema has been a matter of debate. Diallyldisulfide is considered as the main allergen in garlic. Twentv two antigens of the modified European standard series and diallyldisulfide of 5%, 2%, 1%, 0.5%, 0.1% in petrolatum were patch tested in 44 patients with hand eczema. Diallylclisi.!lfide was also tested in 13 women as a control. The results were summerized as follows. l. In patch testing with the European standard series, nickel sulfate (22.7%), cobalt chloride (18.2%), fragrance mix (13.6%), balsam of Peru (9.1%) and termerosal (6.8%) were the cornmon allergens which showed positive reactions. The overal positive rate was 59.1 % (26/44). 2.5% diallyldisulfide showed an irritant reaction in 6 (46.2%) out of 13 controls and in 16 (36.4% ) out of 44 patients. 2% diallyldisulfide showed an irritant reaction in 2/13 (15.4 %) in the control group and 6/44 (13.6%) in the patient group. All 13 controls and 44 patients were negative iin tests with diallyldisulfide of 1%, 0.5%, 0.1%. Our results indicate that patch testing with diallyldisulfide of 1% petrolatum is reommended in order to avoid an irritant reaction when contact allergy to garlic is suspetel. 3. Garlic is suspected as an irritant in provoking hand eczema. True contact allergy to garlic in hand eczema seems to be rare. (Kor J Dermatol 1992;30(2): 197-201)
