Topical immunotherapy with diphenylcyclopropenone(DPCP) has been used for the treatment of alopecia areata. Due to the therapeutic principle of producing a contact eczema, itching, erythema and scaling are inevitable or even desired side effects. However, erythema multiforme-like reactions following topical DPCP treatment have been rarely reported with an estimated incidence of 1.2%. We present herein a case of Stevens-Johnson syndrome, the severe form of erythema multiforme as a side effect of topical DPCP. A 57-year old male patient visited us for the treatment of alopecia totalis. After sensitization with 0.2% DPCP in acetone, we applied DPCP on the scalp once a week for three weeks. Following the 3rd challenge of DPCP, iris-shaped lesions, erosions, vesicles, and bullae developed with fever. Also, he had vesicles and erosions in the oral cavity. The patient was treated with systemic antibiotics, steroids, and antihistamines. The cutaneous lesions were cleared with hyperpigmentation, and pronounced hair regrowth was observed.

We have experienced 4 cases which were clinically diagncsed as granuloma pyogenicum, but histologically as a malignant melanorna, an eccrine angiomatous hamartoma with granuloma pyogenicum, a subungual exostosis, and a lipoma, with granulation tissue. A granuloma pyogenicum may have clinical resemblances to various benign or malignant lesions. Therefore, any lesion that resembles a granuloma pyogenicum should have this clinical impression confirmed by histologic examination.

Chilblain lupus erythematosus(CLE) is a chronic unremitting from of LE seen predomin antly in women, The chilblain lesion occurs commonly on the digits, calves and heels. Chronic facial discoid LE usually appears before the chilblain form. A 23-year-old female had relatively well defined, erythematous discoid plaques on her both cheeks and scattered erythema multiforme-like ring lesions on her right hand and right wrist. There were also chilblain lesions showing multiple, purple colored macules on her knees, lower legs and periungual areas of fingers and toes. The skin lesions developed at November, 1982 and then the skin lesions remitted during the next summer. The skin lesions recurred at December, 1983.

Trichloroethylene is a very common chemical used principally as a solvent and a degreasing agent in industry, We have experienced a case of toxic erythema, toxic hepatitis, and subsequent exfoliative dermatitis possibly due to trichloroethylene in a 23-year-old male. He had dealed with a cleaning process with trichloroethylene in a factory of stainless steel materials. We report our case with the review of the toxicity of trichoroethylene.

OBJECTIVES: The purpose of this study was to find the protective effects of garlic on the halogenated hydrocarbon induced hepatotoxicities, and the possible protection mechanisms involved. METHODS: Male Sprague-Dawley rats received garlic (0.5 %) or regular diet, for 4 weeks. This was followed by a single dose of corn oil (the controls), carbon tetrachloride (400mg/kg body weight) and trichloroethylene (2,000mg/kg body weight) being administered to each diet group. Blood samples were collected 24 hours following the administration, and the serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities measured. The liver samples were studied for their cytochrome P450 and CYP2E1 contents, lipid peroxidation and histopathology. RESULTS: The results for the group receiving the 0.5 % garlic diet showed a slight decrease of CYP2E1 expression compared with the regular diet group. Carbon tetrachloride was significantly decreased the CYP2E1 contents in both the regular and garlic diet groups, but the trichloroethylene remained unchanged. Garlic did not decrease the lipid peroxidation of the liver in the control group, but attenuated the increase of lipid peroxidation caused by carbon tetrachloride. Garlic attenuated the increase of both the serum AST and ALT activities caused by carbon tetrachloride. The histopathological observations also showed that garlic attenuated centrilobular necrosis and vacuolar degenerative changes significantly in the carbon tetrachloride treated group. Conclusions : The results indicate that garlic attenuates the carbon tetrachloride-induced hepatotoxicity, through the prevention of the metabolic activation and lipid peroxidation.

Granuloma annulare is a common, benign, inflamatory, usually self-limited dermatosis. Disseminated perforating granuloma annulare is a rare variant of granuloma annulare. A 23-month-old female patient had asymptomatic, multiple umbilicated papules on the face, limbs including palms and soles, buttock and trunk for about 5 months. The new lesions have developed with mild fever or symptoms of upper respiratory infection. Histopathological examination revealed transepidermal elimination of mucinous degenerated collagen fibers and surrounding palisading lymphohistiocytic granuloma. After she was treated with prednisolone and antibiotics, the lesions slightly resolved, but thereafter, new lesions have developed frequently with mild fever. We herein reported a rare case of disseminated perforating granuloma annulare in the youngest patient yet reported.

Compared with orbital floor fracture, the frequency and significance of medial orbital wall fracture has been relatively ignored because of the lack of proper diagnosis and the difficulty of surgical approach. The surgical delay results to the troublesome complications like enophthalomos, extraocular muscle movement dysfunction. For the reason, it is necessary to measure the exact fracture part and bone defect size with CT scan, the ophthalmologic evaluation and the proper treatment for the indication. We operated on 17 medial orbital wall fracture patients with transnasal endoscopic approach, open reduction through minimal medial canthus incision(6-7 mm), or both methods according to the fracture type. We classified them into three types according to the degree of periosteal injury, the size of the bone defect and the degree of comminution with CT scanning and ophthalmologic evalution. In the case of Type 1, there is no herniation of orbital contents and periosteum is intact despite fracture. The patients of Type 1 can be treated by packing with Foley catheter, Merocel(R) sponge, etc. after bone reduction with transnasal endoscope. In the case of Type 2, which has the herniation of orbital contents and bone defect of approximately 1 cm or less in diameter with periosteum injury, after the bone defect site can be confirmed with an endoscope, the medial wall can be reconstructed by Titanium Mesh, silastic sheet or autogenous bone graft through minimal medial canthus incision. In the case of Type 3, the bone defect is over 1 cm in diameter accompanying comminuted fracture. The fractured medial wall of type 3 can be reconstructed with bone graft through coronal incision or open sky incision. Minor complications occurred in 7 patients but all patients were successfully treated without patient's complaints during the follow-up period of 6-18 months. In addition, the scar by minimal medial canthus incision is imperceptible. The indicaions make the fracture reduction easy and accurate. Especially, it is proper to pediatric patients and young female patients because it corresponds to minimal invasive Technique.

The pleckstrin homology (PH) domain is a protein module of approximately 100 amino acids, that has been found in signaling molecules, including serinelthreonine kinase, GTPase-activating protein, phospholipase, and some cytoskeletal proteins. Although the specific function of PH domain has not been defined yet, it is believed that this domain is involved in the regulation of signal transduction pathway. The expression plasmids of human PLCg PH domains were constructed to see the roles of them in IL-6 signal transduction. When these expression plasmids are transfected into B9 cells, only N-terminal of PH domain inhibited IL-6-induced B9 cell proliferation. These results suggest that N-terminal of PH domain is critical for IL-6 signal transduction in B9 cells. To search the binding proteins associated PH domains of PLCy1 in B9 cells, Glutathione S-trnaferase (GST) fusion proteins containg PH domains were expressed in E. coli. Then, IL-6-dependent B9 cells were treated with 10 unit/ml IL-6 and the cell lysates were immunoprecipited with GST-PH doman fusion proteins. In vitro kinase assay of immune complex demonstrated that p38 (38 KDa) protein was coprecipitated with NC fusion protein, but IL-6 had no additional effect on it. When S-methaionine labelled cell lysates were used for immunoprecipitation, the same result was observed, conforming the association of p38 with NC motive of PH domain.
