Down syndrome is the most, well known autosomal trisomy and e large number of abnormal skin features have been reported to occur in patients with Down syndromir. including syringoma. Syringomas occur with increased frequency in patients with Down syringoma, usually limited to the region around the eyes. but few cases of eruptive syringoma with Down syndrome have been reported. We reported the case of familial eruptive syringoma in a 13 years old patient with Down syndrome.

Skin necrosis is a rare complication of heparin administration that is usually localized to injection sites. We report a case of skin necrosis that was caused by minidose intraarterial infusion of porcine heparin which had been used in a touch to prevent coagulation in percutaneous intraarterial cannula. The skin necrosis appeared 35 days after starting heparin use.

Livedo vasculitis clinically shows purpuric papules and recurrent ulcers in the lower extremities, mainly on the ankles, leaving characteristic scars called atrophie blanche after the healing of the ulcers. Its characteristic histopathologic features and clinical evolution indicate that the common pathologic event is occlusion of vessels in the middle and deep dermis. In Korean literature, seven cases of this disease have been reported but the response of the treatment was not, satisfactory. We report three cases of livedo vasculitis cleared by combined ther by of acetylsalicylic acid, dipyridamole and nifedipine, which has not been reported in Korean literatur.

Hydroa Vacciniforme is a rare, chronic, photosensitivity disorder witli onset in childhood that is characterized by recurrent, discrete vesiculation, necrosis and vacciniform scarring limited to sun exposed skin. We report a case of hydroa vacciniforme associated with ocular inwlvment in which vesicles could be induced only with single MED exposure to UVA.

The indirect technique for making cast restoration requires that dies be as accurate and durable as possible. Currently, stone is the most commonly used material for die. However, it has some problems such as the weakness in its strength and low abrasion resistance. Recently, epoxy resin die systems have become available. The purpose of this study was to examine two commercially available resin die systems and evaluate some characteristics for their clinical performance. This study evaluated the dimensional accuracy of epoxy resins and their wettability with impression materials. In this study, the first experiment was about dimensional accuracy of different die materials. The master model was made of stainless steel. 10 models were made of two epoxy resins (Die-epoxy, Tri-epoxy) and a die stone (Fujirock) each. Occlusal diameter (Dimension I), occluso-gingival height (Dimension II), and interabutment distance (Dimension III) wee measured in each model. Next, the contact angles of die materials with impression materials were observed. The blocks were made of polyether, hydrophilic additional silicone, polysulfide impression materials. By dropping the same amount (0.05ml) of Tri-epoxy, Die-epoxy, and die stone on the blocks, 10 samples of each die material were made. After setting of materials, the contact angles were measured. The results of this study were as follows. 1. The expansion of stone die and the shrinkage of resin dies in occlusal diameter were observed, and stone and Tri-epoxy were expanded and Die-epoxy was shrinked in occluso-gin-gival height. There was little change among materials in interabutment distance (p>0.05). 2. In comparison with the mater model, Tri-epoxy had the least variation in measurement of the three die systems examined. Did-epoxy was next, and die stone showed the greatest variation. 3. The compatibility of die stone for polyether, hydrophilic additional silicone, polysulfide decreased in order, wherease epoxy materials had the decreased compatibility for polyether and polysulfide, hydrophilic additional silicone in order. It was not statistically different between polyether and polysulifide (p>0.05). 4. The contact angles of Tri-epoxy, Die-epoxy, die stone were getting bigger in order.

The purpose of this study was to evaluate and compare the fit of denture bases processed by injection pressing technic using laser scanner of reverse engineering technic. The auther duplicated 20 maxillary edentulous models and 20 mandibular edentulous models, which were scanned on HYSCAN 45C 3D SCANNER(Hymarc Co., Canada). The scanned data was stored in the personal computer using SURFACER (Imageware Co., U.S.A.) software program. After 40 dentures were cured by PERform Inkovac system. SR-Ivocap system, Palajet system, and Sulfon system, they were stored in water at room temperature for 24 hours. The dentures were scanned on HYSCAN 45C 3D SCANNER(Hymarc Co. Canada). The scanned data were stored in the personal computer using SURFACER (Imageware Co., U.S.A) software program. By overlapping two images using the same program, the fit between two surfaces was scaled by positive and negative errors. The obtained results were as follows : 1. In the upper denture, most of the positive errors occurred on the lingual side of anterior alveolar ridge and the negative errors were on the flange of denture bases. 2. In the lower denture, most of the positive errors occurred on the inner side of lingual flange and the negative errors were on the border of anterior labial flange areas. 3. There were no statistical differences among the positive errors of the four types of inject-ion denture curing methods and also no statistical differences between negative errors except only in negative maximum errors. 4. In PRERform system and SR-Ivocap system, they have the tendency of inaccurate fit lower denture bases comparing to that of upper denture bases. 5. The negative error scales were greater than the positive error scales in all types of inject-ion denture curing methods.

BACKGROUND: The high level of susceptibility of patients with liver cirrhosis (LC) to septicemic infection is thought to be due to decreased reticuloendothelial function and irnpairment of several components of cell mediated and humoral immunity. It is well known that LC may cause many characteristic skin changes including jaundice, spider angioma, palmar erythema, xanthelasrna and nail changes such as clubbing and white nails. OBJECTIVE AND METHODS: During a 7 month period frorn April to October 1995, 100 patients who had been diagnosed as having LC were evaluated for the duration of their LC, the associated diseases they had apart from LC and various skin manifestations. Also, we performed the tuberculin test in 20 patients with LC and evaluated the correlation of the tuberculin test with severity of LC divided into 3 groups according to the Childs classification. RESULTS: The results are summarized as follows ; 1. The most frequent duration of LC was under 5 years (74%). 2. The most common associated disease of patients with LC was upper GI bleeding including esophageal varix (24 cases). Also, diabetes mellitus (13 cases) and hepatic coma (11 cases) were observed. 3. Jaundice (82 cases) was the most frequent skin rnanifestation of patients with LC. In addition, vascular changes (81 cases) and various nail changes (69 cases) were observed. Onychomychosis was the most common nail change of patients with LC. 4. 60% of the patients who were given the tuberculin test showed anergy, and the frequency of anergy increased in proport on to the severity of LC. However, it was not significant statistically (p> 0.05 ). CONCLUSIONS: Some of the skin manifestations help in the diagnosis of LC. Also, increased frequency of tuberculin test anergy in proportion to the severity of LC is thought to be related to decreased cell mediated immunity, although statistically it is not significant.

A 38-year-old male patient visited our clinic complaining of three skin lesions on the scalp. There were yellowish to brownish, waxy, non-tender, walnut-sized nodules. Hematoxylin and eosin staining revealed amorphous pinkish material deposits in the dermis. The Congo red stain and Dylon stain under polarizing microscopy showed yellow-green birefringence and the immunoglobulin-lambda light chain stain showed a positive reaction. An electron microscopic examination revealed filaments with uniform diameter(6 to 10nm) that were straight and neither branched nor anastomosed. Based on the clinical, histopathological, immunohistochemical and electron microscopical findings, the skin lesions were diagnosed as nodular amyloidosis.
