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.

We present herein 3 cases of early secondary syphilis with simultaneous primary syphilitic lesions. These cases developed primary syphilitic lesions four to six weeks after sexual contact and lasted six to ten weeks thereafter until the secondary syphilitic lesions appeared. All three patients showed a strong positive for the STS. Spirochetes were seen under dark field examination of the primary syphilitic lesions, Histopathologically, numerous plasma cells around capillaries and endothelial hyperplasia were seen in the dermis.

We have examined the regenerative capabilities of the human scalp hair follicle after grafting the lower half of the follicle. Twenty-eight of 32 intact whole-hair follicles isolated from the human scalp regenerated hairs when grafted onto the forehead of the same person. Seven of the 15 lower-half follicles regenerated complete hair follicles 8 months after grafting showed that the lower-half follicle implant reconstituted the complete hair follicle. The sebaceous gland was not regenerated, but there was an outgrowth in the sebaceous gland regPark ion. Some grafts formed epithelial cysts. Two years after grafting, the histological examination of the regenerated follicle from the lower-half implant showed that the sebaceous gland was completely regenerated. While an intact follicle shows prominent naked shaft outgPark Park Parkrowth, the sheath grows concomitantly with the shaft in lower-half follicles in culture. If grafted lower-half follicles were located too deep, the regrown sheath could not reach the epidermal layer. In this situation, the formation of an epidermal cyst was likely.

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.

Transvaginal bladder neck suspension by Raz is an acceptable procedure for the treatment of stress urinary incontinence with high cure rate, operative simplicity, short hospitalization and little morbidity. Recently we experienced 8 cases of stress urinary incontinence treated with Raz's procedure and 2 cases with coexisting cystocele were treated with 4-corner operation. All cases have been assessed prior to and following operation and the results were satisfactory. Herein, we report 10 cases of stress urinary incontinence treated by Raz's procedure and 4-corner operation with review of literatures.

Allergic contact dermatitis that is attributable to contact with environmental sensitizers boine by a second individual, especially in marital or sexual relationships, has been described as connubial contact dermatitis. Severely pruritic multiple erythematous plaques, vesicles and bullae in a 35-year-old woman occurred on the face, posterior area of the neck, breasts, buttock, and both upper arms. No direct contact to allergens was obtained. However her husband had eaten some cooked sprouts from a lacquer tree for lunch at a restaurant the day before her eruption, then he caressed her that night. A patch test with extracts of lacquer tree in ethanol(2%), crushed extracts of lacquer tree (as is), and urushiol(0.002% pet.) on the patients back showed strong positive reactions.
