We report herein a case of polymorphic pemphigoid in a 65-year-old woman, who had one-year history of generlized polymorphic eruption with intensely pruritic excoriated vesicobiullous lesions and residual pigmentation. Face and oral mucosa were spared. The skin biopsy specimen showed a subepidermal blister containing many eosinophils. Linear deposition of 1gG and C3 along the basement membrane was noticed on direct irnmunofluorescerice. Polyclonal garnmopathy with a tendency of beta-gamma bridging and increased IgG, IgA and kappachain, was frund on serum protein electrophoresis and immunoelectrophoresis. Skin lesions were well coritrolled by a combined therapy of prednisolone(20 mg/d), dapsone(100 mg/d) and cyclophosphamide(100 mg/d) for 4 months. Direct immunofluorescence performed 11 rnonths after the cnmpletion of the therapy was negative.

Indirect composite resin are used as an popular effective esthetic material in prosthetic dentistry, often with metallic substructure that provides support for restorations. Recently, new indirect composite resins as a substitute of ceramic have been developed. These resins provide good esthetics, with a wide range of hue and chroma. And the flexural strength of those is in the range of 120-150MPa, which is higher than that of feldspathic ceramic, and similar tot hat of Dicor. Although it has many merits, one of the major clinical problems of composite resins is the bond failure between metal and resin due to insufficient interfacial bond strength. The purpose of this study was to evaluate shear bond strength of the reinforced indirect composite resin to dental alloys. Three different composite resin systems(Artglass . Sculpture , Targis ) as test groups and ceramic(VMK 68 ) as control group were bonded to Ni-Cr-Be alloy(Rexillium III ) and gold alloy(Dave 4). All specimens were stored at 37degrees C distilled water for 24 hours and the half of specimens were thermocycled 2000 times at temperature from 5degrees C to 60degrees C. The shear bond strengths of reinforced indirect composite resins to dental alloys were measured by using the universal testing machine, and modes of debonding were observed by stereoscope and scanning electron microscope. The results were as follows : 1. The shear bond strengths of reinforced indirect composit resins to dental alloys were approximately half those of ceramic to dental alloys(P<0.01). 2. There was no significant difference between the shear bond strength of several reinforced indirect composite resins to metal. 3. Alloy type did not affect on the shear bond strengths of resin to metal, but the shear bond strengths of ceramic to gold alloys were higher than those of ceramic to Ni-Cr alloys(P<0.05). 4. The shear bond strenghts of Artglass and Targis to gold alloys were significantly decreased after thermocycling treatment(P<0.01). 5. Sculpture showed cohesive, adhesive, and mixed failure modes, but Artglass and Targis showed adhesive or mixed failures. And ceramic showed cohesive and mixed failures.

PURPOSE: Knee IVIR images were repeatedly obtained after intravenous administration of gadopentetate dimeglumine to evaluate the arthrographic effect and to determine the optimal scan timing and technique. MATERIALS AND METHODS: Sagittal Tl-weighted (650/15) sequences were repeated before and after intravenous gadolinium enhancement in 26 patients who were divided into exercise (14/26) and nonexercise (12/26) groups. Fourteen patients in exercise group were allowed to move the affected knee joint actively for 10 minutes immediately after the first post-enhancement scan and before repeating scans. The signal intensities in central and peripheral portions of the joint were measured and compared between these two groups. RESULTS: In all cases, enhancement of joint fluid began at peripheral portion and progressed toward central portion. The diffusion rate in exercise group was far faster than that in nonexercise group and homogeneous arthrographic image was revealed within 10 minutes after completion of joint movement. The arthrographic effect continued and the rate of signal decrease was quite slow. CONCLUSION: MR arthrographic image of knee joint can be obtained within 10 minutes after completion of a few minute exercise following intravenous injection of gadopentetate dimeglumine. Intravenous MR arthrography is expected to become an useful method as a convenient alternative to direct MR arthrography.

OBJECTIVE: The purpose of this study was to identify the clinicopathologic characteristics, treatments and overall 5-year survival and to analyze the prognostic factors affecting the survival in patient with ovarian tumors. METHODS: We reviewed retrospectively the outcome of 116 patients with ovarian cancer and 64 patients with borderline malignant ovarian tumor, who had been treated at Department of Obstetrics and Gynecology, Korea University Anam Hospital from Jan. 1991 to Dec. 2001. Univariate and multivariate analysis for survival were conducted to test the prognostic significance of several clinicopathologic factors. RESULTS: The mean age of the patients with borderline malignant ovarian tumor was 39.9 years old, and nulliparity was most common (42.2%). Mucinous tumor was the most common histologic subtype (68.8%). The FIGO stage distribution of borderline malignancy were 89.1%, 1.6%, 9.3% for stage I, II, and III, respectively. The overall 5-year survival rate of patients with borderline malignancy was 98.4%. The mean age of the patients with ovarian cancer was 50.1 years old. The incidence of ovarian cancer according to histologic type were 74.1%, 12.9%, 11.2%, 0.9%, 0.9%, in epithelial ovarian cancer, Sex-cord stromal tumor, malignant germ cell tumor, metastatic carcinoma of the ovary, and small cell carcinoma, respectively. The FIGO stage distribution of ovarian cancer were 40.5%, 12.1%, 42.2%, 5.2% for stage I, II, III, and IV, respectively. The overall 5-year survival rate of patients with ovarian cancer was 60.9%. In multivariate analysis, FIGO stage was identified as a significant independent prognostic factor in this study. CONCLUSION: In this study, patients with borderline malignancy of the ovary have good prognosis and the overall 5-year survival rate was 98.4%. Otherwise, the overall survival rate of patients with ovarian cancer was 60.9% and the stage was most important prognostic factor.

Uterine sarcomas are relatively rare tumors of mesodermal origin that constitute 2-6% of uterine malignancies. Uterine sarcomas include endometrial stromal sarcoma (ESS), leiomyosarcoma (LMS), malignant mixed m llerian tumor (MMMT) of both homologous and heterologous type, pure heterologous sarcomas, blood vessel sarcomas, and lymphoma. Endometrial stromal tumors are divided into three types: 1) endometrial stromal nodule, 2) low-grade stromal sarcoma or endolymphatic stromal myosis, and 3) endometrial stromal sarcoma. The low grade endometrial stromal sarcoma is very rare. It shows occasional local recurrence, which might arise from endometrial stroma, from adenomyosis, and rarely from endometriosis. We have experienced a case of low grade endometrial stromal sarcoma of the uterus in a 54-year-old woman, which is presented with a review of literatures.

Authors investigated the effect of the timing of vitrectomy for endophthalmitis on the final visual acuity, by retrospectively reviewing the clinical records of patients who have undergone pars plana vitrectomy for the treatment of endophthalmitis from Feb. 1990. Twenty one cases(21 eyes) were included who were followed up for 6 months or longer after surgery and intravitreal injection of antibiotics. 14 cases were male. The age ranged from 28 to 81 years, with mean age of 40.5 years. Ten cases arose from intraocular surgeries, with 7 cases of early-onset and 3 cases of late-onset, the other 10 cases were related to ocular trauma and the remaining one case was associated with a filtering bleb. Intravitreal injections, subconjunctival injections and topical eye instillation of antibiotics were preformed as an initial treatments on cases whose retina were invisible due to severe inflammatory media opacities. Those cases who did not respond to initial treatments were divide into two groups: one which underwent early vitrectomy within 2 days, and the other which underwent late vitrectomy after 2 days. Ten out of 12 cases among early vitrectomy group and 3 out of 9 cases among late vitrectomy group obtained final vision of 0.1 or better. The cases which underwent early vitrectomy showed good visual prognosis with statistical significance(P<0.05). Therefore, authors suggest that management of endophthalmitis with initial severe inflammatory reactions should include early diagnosis, and early vitrectomy with intravitreal infection of antibiotics for recovery of maximal visual acuity.
