We report s case of angiokeratoma of the vulva occuring in a 36-year-old woman. Numerous grayish dark purple papulovesicular lesions, ranging from 0.2 to 2.0mm in size, were observed on the right labium majus. All lesions were excised under local snesthesia after the diagnosis of angio keratoma was made histopathologically. No new lesions appeared during the follow-up period of one year.

Blood utilization review has recently been used to minimize inappropriate transfusion, reduce post transfusion infections and improve the quality of transfusion practices. Ajou University Hospital is a 906 bed tertiary care teaching institution. Since March, 1995, the concurrent review of blood transfusion requests using institutional blood transfusion criteria has been initiated. To evaluate the effectiveness of the transfusion review, the units of blood components transfused per patient(total number of units of blood components transfused/total number of patients discharged) and inappropriate transfusion ratio of blood components(total number of units of blood components inappropriately transfused/total number of units of blood components transfused) were compared during the concurrent review for 9 months and pre-concurrent review for 9 months, respectively. The possible savings of blood components realized by the review were also extrapolated. The results were as follows : 1. The unit transfused per patient for pre-review and during review were 0.675 (9,080/ 13,422) and 0.654(12,123/18,546) for packed RBC(PRBC); 0.417 (5,602/ 13,422) and 0.296 (5,444/18,546) for fresh frozen plasma(FFP); 0.372(5,007/13,422) and 0.424(7,868/18,546) for platelet con-centrates(PC), respectively. 2. The inappropriate transfusion ratio of blood components for pre-review and during review were 0.039 and 0.009 for PRBC; 0.321 and 0.064 for FFP; 0.143 and 0.008 for PC, respectively. These differences were statistically significant(p=0.000). 3. The PRBC and FFP anticipated to have been saved by this review was 519 units and 2,992 units annually, respectively. 4. However, 2,621 units of PC were used additionaly during this review due to increased number of oncology patients and better hemostatic therapy practiced during the same period. In conclusion, the concurrent review of transfusion requests was very effective tool to educate residents in clinical departments the transfusion medicine and improve utilization of blood and its components.

Dislocation of peroneal tendons are caused by forceful domifiexion of the foot accompanied by a powerful contraction of the peroneal muscles. This mechanism of injury tears the superior pemneal retinaculum and allows the tendons to snap anteriorly. It is an important, although infrequent, cause of disability of the ankle. The acute injury can be treated by immobilization in a plaster cast, but when there is chronic recurring dislocation, surgical reconstruction is necessary. Authors experienced two cases of dislocation of pemneal tendons which were treated by use of Sarmiento's and Platzgummer's(modified) operative procedures with good results.

During the previous several decades the osseointegrated implants have been considered as the most ideal therapy for the fully edentulous or partially edentulous patients. Although the research on the biocompatibility of osseointegration, the oral tactile function, and the histo-neurologic study had been performed, the change of the oral tactile sensibility and maximal occlusal force according to the postinsertion time of implant prostheses has not been studied. The purpose of this study was to compare the oral tactile sensibility and maximal occlusal force of implant prostheses to natural teeth according to the specific postinsertion time intervals. The fifty seven patients treated with Br adegreenemark implants during the recent seven years were involved in this study. The oral tactile sensibility and maximal occlusal force were measured according to the postinsertion time (o6 months, o12 months, o18 months o24 months, and o25 months) 1.The passive tactile threshold of implants was higher than 6-7 times when comparing to natural teeth(P<0.05). 2.The absolute pressure threshold in horizontal and vertical direction for the passive tactile sensibility had decreased significantly in the post insertion time 13-18 months group and had increased significantly in the post insetion time over 25 months group (P<0.05). 3.50% limit thickness and 100% absolute thickness for the active tactile sensibility had decreased significantly in the postinsertion time 7-12 months group (AT50 : P<0.005, AT100: P<0.05) 4.The maximal occlusal force of the implants prostheses had decreased when comparing with natural teeth in the postinsertion time 1-6 months group(P<0.05) and after that there was no significant difference between the implant prostheses and natural teeth(P<0.05). 5.Maximal occlusal force according to the postinsertion time had increased significantly in the 13-18 months group (P<0.05),after that there was no significant difference. 6.There was positive correlation between age and oral tactile sensibility tested in horizontal and vertical direction (PH:r=0.39, PV:r=0.41) and there was no correlation between age and maximal occlusal force, age and active tactile sensibility 7.According to the results or the questionnaire, 76.6% of the patients were satisfied with the function and 96.7% of the patients were satisfied with the sensibility. In conclusion oral tactile sensibility and maximal occlusal force of implants have changed with the postinsertion time. Oral tactile function of implants was lower than that of the natural teeth, but for the maximal occlusal force there was no difference between implants and natural teeth.

We experienced a case of primary hepatic actinomycosis which was initially diagnosed by means of fine needle aspiration. The patient was a 31-year-old emaciated man with a 2-month history of 10 kg weight loss, right upper quadrant pain and flank pain. The liver was palpable and tender on physical examination. Computerized tomography scan of the liver showed two ill-defined hypodense masses in gallbladder fossa and inferior pole of right lobe. Hepatocellular carcinoma was clinically suspected. A CT-guided fine needle aspiration was performed. Microscopically, smears showed numerous radiating clusters of filamentous bacteria with many neutrophils and monocytes in necrotic background. The symptoms were improved by incision and drainage and massive administration of penicillin.

We report two cases of hyperkeratosis of the nipple and areola which occurred in 22-year-old woman and 13-year-old girl. The former was suffered from mild pruritic, verrucous thickening and brownish discoloration of both nipples and areolae for 5 years. The latter had asymptomatic, verrucous thickening and dark brownish hyper- pigmentation of the right nipple and areola for 3 years. Both showed mild to marked hyperkeratosis and papillomatosis with increased pigmentation in the basal cell layer histopathologically. In both cases, the lesions were not responsive to the topical medications including steroids and keratolytic agents. Therefore we recommended surgical excision because the patients are greatly disturbed by the appearance of the lesions.

The purpose of this study was to compare surface roughness and bone formation around two types of threaded commercially pure titanium implants manufactured by two different companies. The test implants were manufactured by Sumin synthesis dental materials Co. (Avana, Busan, Korea), while the controls were manufactured by Nobel Biocare (MK II, Goteborg, Sweden). To compare bone formation adjacent to newly product with Branemark MK II implant, surface roughness was measured by Accurate 1500M and histomorphometric analysis was done. The results were as follows : 1. Measurement of surface roughness showed that Avana implant had a slightly more irregular surface compared with Branemark implant. 2. In the light microscopic studies, no infiltration of inflammatory cells nor the giant cells wee observed on both groups. 3. In th light and fluorescent microscopic studies, the amount of osseointegration and the extent and the timing of bone formation were similar. 4. There were no statistically difference between two groups in the average bone to implant contacts. Branemark implant ; 67%(SC 23%), Avana implant ; 70%(SD 16%). Comparing with Branemark implant, Avana implant made of CP grade II titanium showed similar good bone healing, formation and osseointegration.

Purpose: To evaluate the clinical outcomes of a non-diffractive extended-depth-of-focus (EDoF) intraocular lens in eyes by epiretinal membrane (ERM) stage. Methods: Clinical records of 289 eyes with AcrySof® IQ Vivity TM (Alcon Laboratories) implantation were reviewed. Eyes were grouped according to ERM stage as no ERM (n = 228), stage 1 (n = 29), stage 2 (n = 20), and stage 3 (n = 12) ERM. Corrected and uncorrected distant visual acuity (CDVA and UDVA, respectively), uncorrected intermediate and near visual acuity (UIVA and UNVA), contrast sensitivity detected by the area under the log contrast sensitivity function (AULCSF), Strehl ratio, area ratio, and intraocular aberration were compared. Results: There was no difference in UDVA, UIVA, UNVA, or CDVA between groups (p = 0.639, p = 0.871, p = 0.963, and p = 0.051, respectively). There was no significant difference in Strehl ratio (p = 0.208), area ratio at 4 mm (p = 0.434), area ratio at 5 mm (p = 0.511), or ocular aberrations (p = 0.311 for total aberration). The AULCSF showed significant differences during both day (1.48 ± 0.21, 1.41 ± 0.18, 1.33 ± 0.17, and 1.31 ± 0.19 for no ERM, stage 1, stage 2, and stage 3 ERM, respectively; p = 0.036) and night (1.21 ± 0.21, 1.22 ± 0.12, 1.02 ± 0.20, and 1.08 ± 0.10 for no ERM, stage 1, stage 2, and stage 3 ERM; p = 0.027). Conclusions Eyes with stage 3 ERM without outer retinal involvement may benefit from EDoF technology when there is no metamorphopsia and when accompanied by timely membrane removal.
