We herein report a case of AIDS-related Kaposi's sarcoma (KS) in a 36-year-old male patient, who had a solitary nodular skin lesion on the left supraclavicular area. The histopathologic findings showed typical features of KS as spindle cell proliferation and vascular spaces lined with endothelial cells. The patient's serum was positive for antibodies to the human immunodeficiency virus (HIV) and he had opportunistic infection of Pneumocystis carinii pneumonia and pulmonary tuberculosis. The WBC count was 1,200/mm3 and CD4 count was 50/mm3 with decreased CD4/CD8 ratio to 0.06. He died due to an aggravated respiratory infection.

Purpose: this study was to evaluate the fitness of adjustable dental impression trays on the Koreans : the trays used in the previous study by Kim et al. as part of the dental adjustable tray development project were improved and modified. Material and method: The patterns of tray were made through CAD-CAM process, and a simple silicone-base molds were made from them. The trial products were reproduced by pouring polyurethane into these molds. 30 male students(Wonkwang University, Dental College) and 30 female students (Wonkwang Health Science College, Department of Dental Hygiene) were selected and Reversible hydrocolloid impression materials were used for this study. The fitness of the trays was evaluated by measuring the width and length of impression materials of each measurement sites. Results and conclusion: 1. In adapting the trays inside the mouth, a uniform width of impression material(3.6mm) was obtained in most sites due to the tooth stops and the inclined planes accommodating the width of the tray. 2. The thickness of impression material in the central part of the palate was a mean 9.8 mm, which turned out to be somewhat thick. 3. In the mandible, the thickness of the impression material in the lingual side inferior to the contact point of the 1st and 2nd molars was 2.7mm, and the thickness of the material in the lingual side of the rearmost margin was 2.5 mm. The thickness of the impression material of these areas was relatively thin.

Erythropoietic protoporphyria(EPP) is an inherited inborn error of porphyrin metabolism caused by decreased activity of the enzyme ferrochelatase. EPP is characterized clinically by photosensitivity to visible light commencing in childhood, and biochemically by elevated red cell free protoporphyrin levels. We report herein a case of EPP which occurred in a 44-year-old man and his family. He had suffered from immediate photosensitivity since he was 4 years old. He was presented with burning, erythema, scars and waxy thickening of the sun-exposed skin. Red cell free protoporphyrin level was elevated and urinary porphyrins were normal. Histopathologically, homogeneous eosinophilic materials that stained with PAS were deposited in perivascular area of upper dermis. He was managed with light restriction and sunscreen.

Cutaneous leishmaniasis is usually a self-limited infection of skin caused by the genus Leishmania, transmitted by a sandfly. This disease is endemic in tropical and subtropical zone, but recently several cases of cutaneous leishmaniasis were reported in Korean who had worked in Middle East. We report a case of cutaneous leishmaniasis in a 24-year-old male patient, who had travelled in Africa.

PURPOSE: The aim of this study was to evaluate the clinical value of Osstem(R) USII plus system implants. Clinical and radiographic data were analyzed for 88 implants placed and functionally loaded for a 12 month period at the Yonsei University Dental Hospital. MATERIALS AND METHOD: Based on the patient's medical records, clinical factors and their effects on implant marginal bone resorption, distribution and survival rate were analyzed. The marginal bone loss was evaluated at implant placement and during a 6 to 12 months functional loading period. The independent sample t-test was used to evaluate the interrelationship between the factors (alpha=0.05), and one way repeated measures ANOVA was used to compare the amount of marginal bone resorption. RESULTS: The cumulative survival rate for 88 implants was 100%. The marginal bone resorption from implant placement to prosthetic delivery was 0.24 mm and the average marginal bone resorption from prosthetic delivery to 12 months of functional loading was 0.19 mm. The total average bone resorption from implant placement to 12 months of functional loading was 0.43 mm. There were no statistically differences in the amount of marginal bone resorption when implants were placed in the maxilla or the mandible (P>.05), however, implants placed in the posterior areas showed significantly more marginal bone loss than those placed in the anterior areas (P<.05). CONCLUSION: Based on these results, the short term clinical success rate of RBM surface treated external connection domestic implants showed satisfactory results and the marginal bone loss was in accord with the success criteria of dental implants.

A clinical analysis of infective endocarditis was done in 34 patients who were admitted to National Medical Center from march. 1972 to June. 1984, and the results were as follows. 1) There was no difference in ratio between sexes. The prevalence was highest in the 3rd decade. 2) The important preexisting heart diseases were rheumatic heart disease(32.4%), congenital heart disease(17.6%) and undefined cardiac condition(20.6%) in order of frequency. 3) The common symptoms and signs on admission were fever(88.3%), cardiac murmur(79.4%), malaise(70.6%), dyspnea (64.7%), palpitation(55.9%) and hepatosplenomegaly(55.9%). 4) The positive blood culture was obtained in 15(47%) of the cases. Those who had not received antibiotics before admission showed higher rate of positive culture(72.7%) than in those who had received(33.3%). 5) The laboratary findings revealed anemia(73.5%), leukocytosis(35.3%), increased ESR(73.5%), microscopic hematuria(61.8%) and positive CRP(100.0%). 6) The EKG findings showed normal(11.8%), sinus tachycardia(32.4%), LV hypertrophy(29.4%), non-specific ST-T change(20.6%) and AV block(14.7%). 7) Vegetation was detected by echocardiography in 43% of cases and the most frequently involved valve was aortic(66.7%). 8) The combination of penicillin and aminoglycoside was effective in 86.4% of patients so treated.
