Purpose: We report two brothers having dissociated vertical deviation with microtia and familial history of the condition. Methods: The subjects of this report are a 7-year-old patient with bilateral dissociated vertical deviation, exotropia, bilateral inferior oblique muscle overaction, and microtia, and his brother, a 6-year-old with bilateral dissociated vertical deviation, right dissociated horizontal deviation and microtia. Results: The first patient underwent asymmetric bilateral lateral rectus muscle recession and bilateral inferior oblique muscle myotomy, while the second patient had asymmetric bilateral lateral rectus muscle recession. In the first patient, the exotropia was corrected, but the bilateral dissociated vertical deviation and left dissociated horizontal deviation remained. The right dissociated horizontal deviation improved in the second patient. Their father, two aunts and paternal grandmother also had strabismus and microtia. Conclusions: Physicians must investigate familial history in examining the strabismus patient with microtia. Additionally, genetic investigation is in need in more subjects of this study.

Purpose: This study investigated the surgical results and nasal findings of an endoscopic dacryocystorhinostomy according to differences in nasal mucosal and lacrimal bone opening size. Methods: This investigation included 40 eyes of 35 patients who had undergone endoscopic dacryocystorhinostomy by nasolacrimal duct obstruction between February 2003 and December 2004. Comparisons of nasal mucosal opening with lacrimal bone opening were performed using of digital images recorded during the operations. Opening size was defined as the definite to average length of the long and short axes of each opening. Success rates were evaluated by postoperative subjective symptoms and syringing findings. Postoperative nasal cavity findings were obtained by endonasal evaluation. The results were verified by the Pearson chi-square test. Results: The success rate was higher in the group with a nasal mucosal opening size at least twice as wide as their lacrimal bone opening size (84.62%) compared to the group with a nasal mucosal opening sizes less than twice as wide as their lacrimal bone opening size (78.57%), but the difference was not significant (p=0.78). Granulation tissues were observed at a significantly lower rate in the group with nasal mucosal opening sizes at least twice as wide as their lacrimal bone opening size. Conclusions: Large resection of nasal mucosa in endoscopic dacryocystorhinostomy can improve the result by decreasing the granulation formation.

Purpose: This study investigated the differences of muscle width and distance from limbus to muscle insertion site according to age and sex, and the correlation with ocular axial length and strabismus degree. Methods: The study subjects were 100 eyes of 50 horizontal strabismus patients undergoing rectus muscles recession. Ocular axial lengths were measured at preoperation, while muscle width and distance from limbus to muscle insertion site were measured during operation. Preoperative and postoperative comparison items were retrospectively investigated with the medical records. Correlations of muscle width, distance from limbus to muscle insertion site and the comparison items were verified by ANOVA test. Results: Muscle width was 10.05±0.86 mm in medial rectus muscle and 9.38±1.03 mm in lateral rectus muscle. Distance from limbus to muscle insertion site was 5.21±0.85 mm in medial rectus muscle and 6.37±1.01 mm in lateral rectus muscle. Muscle width and distance from limbus to muscle insertion site had no correlations with ocular axial length and strabismus degree, but ocular axial length was significantly longer in the older group compared to the younger group and in the male group compared to the female group. Conclusions: It is presumed that muscle width and distance from limbus to muscle insertion site have no relationship with age, sex and strabismus degree.

Erythema nodosum has been known to be frequently associated with some kind of drug, infections with streptococci, mycobacteria, lymphogranuloma venerum and certain unknown pathogenic processes such as sarcoidosis, iilcerative colitis and regional enteritis. However, the association of erythema nodosum with leukemia has rarely been reported. Erythema nodosum with leukemia has been divided into leukemia cutis with specific infiltration of atypical leukemic cells and leukemid with non specific infiltration of normal infilammatory cells. We report herein a case of the very rare but typical erythema nodesum showing nonspecific infiltrative panniculitis as an initial manifestation of chronic myelocytic leukemia.

Dermatofibrosarcoma protuberans(DFSP) is a rare, distinctive cutaneous tumor, which consists of spindle shaped ceils arranged in densely packed interlacing bundles with the storiform or cartwheel pattern. Histologically, it resembles deep growing dermatofibroma, nodular fasciitis, neurofibroma and neural sheath tumors. DFSP is one of t.he connective tissue tumors which is difficult. to diagnose histologically as well as clinically. Recently, the immunochemical staining with a monoclonal antibody to CD34 is reported to give assistance in the clear differential diagnosis of DFSP from other fibrous or neural tumors. Herein, three cases of DFSP were stained by immunohistochemical staining with S-100 protein, vimentin, factor VIII and anti-CD34 antibody in order to assess the use of anti-CD34 in the differential diagnosis of DFSP.

본 논문에서는 크게 2단계에 걸쳐 다양한 형태의 얼굴을 가진 2차원 애니메이션 상의 캐릭터 얼굴구성요소를 추출하고 표정을 분석한다. 첫 번째 단계에서는, 기존의 얼굴인식 및 표정인식 분야에서 이용되었던 동적메쉬모델을 간소화하여 캐릭터 얼굴에 적용하기 위한 최적의 표준 메쉬모델을 제작하고, 이 모델을 사용하여 얼굴구성요소의 위치 및 형태정보를 추출한다. 두 번째 단계에서는, 앞 단계에서 추출된 3가지 얼굴구성요소(눈썹, 눈, 입)를 사용하여 FACS(Facial Action Coding System)에 정의된 AU(Action Units) 44개 중 12개의 AU를 사용하여 캐릭터의 5까지 기본적인 얼굴 표정에 대해 분석 및 정의한다. 본 논문에서 정의한 AU로 기본적인 5가지 얼굴표정에 대해 표정분석 정확도를 측정하였고, 서로 다른 캐릭터에 실험함으로써 제안된 AU정의의 타당성을 제시한다.

Background: With progressive improvement in the fraction of long-term surviviors, chronic GVHD has emerged as a increasingly frequent complication of allogenic bone marrow transplantation. Except for a few case reports, there has been no clinical study of chronic cutaneous GVHD in Korea so far. Objective : In the present study we planned to investigate the clinical characteristics of chronic cutaneous GVHD and to compare the clinical manifestation and incidence of chronic cutaneous GVHD in Korea with previous reports in U.S.A. and Europe. Methods : On the basis of the patients' charts and the records of bone marrow transplantation, we investigated the incidence of chronic cutaneous GVHD in Korean leukemia patients and studied the clinical manifestations of chronic cutaneous GVHD ocurring in 16 patients whose diagnosis was confirmed by histopathologic findings of skin biopsy. We also analysed whether total body irrdiation before bone marrow transplantation, GVHD prophylaxis and presence of preceding acute GVHD affected chronic cutaneous GVHD. Results : 1. The incidence in chronic cutaneous GVHD in Korea was lower than that in Caucasian countries. 2. The onset was milder than that in Caucasians. 3. The clinical manifestation was earlier than that in Caucasians. 4. The relationship between the GVHD prophylaxis and incidence chronic cutaneous GVHD was not significant. 5. The incidence of chronic cutaneous GVHD in the presence of preceding acute GVHD was higher than in cases with no preceding acute GVHD. Conclusion: We speculate that the low incidence of chronic cutaneous GVHD and clinical characteristics differing from the reports in the U.S.A. and Europe might be unassociated with irradiation, GVHD prophylaxis or the presence of preceding acute GVHD but maybe related to differences in genetic background.
