We describe the clinical and pathologic observation of a 50-year-old man with superficial disseminated porokeratosis who developed a squamous cell carcinoma on the dorsum of his right thumb and Bowens disease on his right upper arm. The tumors were surrounded by lesions of superficial disseminated porokeratosis and were thought to develop from the dysplastic epidermal cells located under the comoid lamellae.

Acquired tufted angioma is a benign, slowly progressive angioma with a characteristic histologic pattern, that was first described by Wilson Jones in 1979. We present herein a case of this rare disease developed in a 43 year old healthy woman. Routine biopsy specimens and an immunoenzymatic staining of factor 7IE showed compatible findings with those cases reported previously. The lesions were surgically excised, and during the two months of follow up, there was no sign of recurrence.

Dentocutaneous fistula of the face neck is an infrequent manifestation of chronic dental infection. A periapical dental abscess may be initiated by disease, trauma, or thermal or chemical injury and develops into an extensive necrosis of surrounding tissue. Diagnostic errors can result in multiple excision, biopsies, and ineffective long-term antibiotic therapy. Awarness that periapical dental abscess is the most common etilolgic factor of cutaneous sinus tracts involves the face & neck will facilitate their early diagnosis and prevent needless treatment or anxiety for the patient. From 1994 to 1998, we have performed 6 cases of dentocutaneous fistula. Among of them, three were men and the others were women, age ranged from 18 to 66-year-old, and morbidity period was from 3 weeks to 3 years, the follow-up period ranged from 5 to 18 months (mean period 11 months). In conclusion, an understanding of the pathogenesis of cutaneous fistulae arising from dental infections will lead to proper early diagnosis and treatment without unnecessary surgery.

Five cases of childhood candidal vulvovaginitis, each having clinical features of vulva erythema, pnuritus, and vaginal discharge, were examined. Circumst. antially, t.he suspected sources of infection and the attributatble factors for the candiclal nfection in these patients were mother of the children who had known candidal vulvovaginitis, and chronic diarrhea of the children. Regarding the treatment of these patients, 3 were given oral ketocanazole and 2 were treated with intravaginal clotrimazole preparations for more than 1 week with successful result. Concern for better hygiene in the anogenital area seems to be important in the prevention of childhood candidal vulvovaginitis.

Dyschromatosis universalis hereditaria is a rare pigmentary disorder initially described in the Japanese literature. The pattern of inheritance is believed to be autosomal dominant, but many sporadic cases have been reported. We encountered a family in which dyschromatosis universalis hereditaria occurred in seventeen members of three generations. In the two members whom we observed, typical skin lesions were distributed all over the body except palrns and soles. By pedigree analysis, we found an autosomal dominant pattern of inheritance. The differential diagnosis of the other reticulate pigmentary disorders is discussed with a review of dyschromatosis reported in the Korean literature.

STATEMENT OF PROBLEM: A tenderness of the dentin after tapering of teeth for dental prosthesis is a common phenomenon. In practice, the alternative desensitizer may be used for minor pain after tapering of teeth. PURPOSE: In this study, the desensitizers were used to investigate the affect decreasing of shear bond strength according to the use of various cement, such as resin, Glass Ionomer, and phosphate cement. MATERIAL AND METHOD: Three different desensitizers were used on this study. Compositions of two dentin desensitizers were HEMA(hydroxyethylmethacrylate) and glutaraldehyde. The other one is oxalic acid. Three dentin desensitizers applied on 12 degrees taper teeth. Then, Ni-Cr crowns were bonded with Resin cement, Zinc Phosphate (ZPC) cement and Glass Ionomer (GIC) cement. 120 human premolar teeth were used for specimens. The specimens were divided into four group as the reference and the empirical each with thirty specimens, then further divided into 12 group according to type of desensitizers and cement types. The shear bond strength were measured by Instron multi task instrument. RESULTS: According to the result, the measured shear bond strength in order from the weakest to the strongest in general was ZPC, Resin, and GIC. And it is found that the application of desensitizers on dentin surface does not affect the shear bond strength. CONCLUSION: Dentin desensitizers that alleviate or prevent a dentin tenderness, usually contains HEMA and glutaraldehyde compounds. Such desensitizers are widely used in clinical studies. By applying the dentin desensitizer on the exposed dentin surface, the dentin capillary are blocked and periodontal membrane and cementum can not be drawn in pulp cavity. Since HEMA and glutaraldehyde may cause harm to the pulp cavity, an alternative desensitizer was developed.

PURPOSE: To evaluate the usefulness of locking compression plate (LCP) and volar plating through anterior approach for distal radius fracture. MATERIALS AND METHODS: We retrospectively analysed that 15 distal radius fracture, which would not be reduced by closed reduction or too comminuated to maintain reduction or articular surface inconguency, were treated by open reduction through anterior approach and volar plating using LCP. The results were evaluated by preoperative and postoperative radiographs. Functional results were analysed using the Modified Mayo Wrist Scoring System. RESULTS: All cases achieved anatomical articular surface reduction postoperatively. In terms of radiologic analysis, mean radial length (9.0 mm vs. 11.8 mm), radial inclination (14.7degrees vs. 20.9degrees ), volar tilt (-6.3degrees vs. 8.3degrees ) and articular step-off (1.4 mm vs. 0.3 mm) were improved. The average Modified Wrist Score was 89. Nonunion or malunion was not occurred. CONCLUSION: Open reduction through anterior approach and volar plating using LCP is a useful method that provides excellent results with few complications in the treatment of fracture of the distal radius.
