목적: 가와사키병이 있는 소아에서 진단 및 결과 예측에 있어서 Bacille Calmette-Guerin (BCG) 접종 부위 반응의 임상적 중요성을 알아보고자 하였다. 방법: 2006년 1월부터 2017년 2월까지 가와사키병으로 서울아산병원에 입원한 1,058명의 환자를 대상으로 각 연령대에서 BCG 부위 반응의 발생 빈도를 조사하였다. 이 중 생후 18개월 미만인 416명의 환자를 BCG 부위 반응과 실험실 및 임상 소견들과의 연관성을 분석하기 위한 대상자들로 선정하였다. 분석은 완전형과 불완전형 발현 두 그룹으로 구분하여 수행되었다. 결과: 1,058명의 환자들을 관찰한 결과, BCG 부위 반응의 발생률은 생후 6-12개월(83%) 연령의 환자에게 가장 많았고, 12개월 후 연령이 증가함에 따라 감소했다(P<0.001). BCG 부위 반응은 생후 18개월 미만 환자의 70%이상에서 발생하였고, 경부 림프절 종대보다 빈발했다. 로지스틱 회귀분석결과, 결막염(P=0.781), 입술/구강의 변화 (P=0.963), 발진 (P=0.510), 경부 림프절 종대 (P=0.363), 사지 말단의 변화 (P=0.283) 및 관상 동맥류 (P=0.776)는 BCG 부위 반응과 관련이 없었다. 결론: BCG 부위 반응은 BCG 예방 접종을 받은 18개월 미만 소아에서 가와사키병의 주요 임상 소견과는 독립적으로 유용한 진단 도구가 될 수 있다는 것을 확인하였다. 관상동맥 합병증 결과는 완전 가와사키병 및 불완전 가와사키병 모두에서 BCG 부위 반응이 있거나 없는 그룹간에 차이가 없었다. Purpose: The purpose of this study was to investigate the clinical significance of Bacille Calmette-Guerin (BCG) site reaction in terms of diagnosis and outcome prediction in young children with Kawasaki disease (KD). Methods: The incidence of BCG site reaction in the respective age ranges was investigated in 1,058 patients who were admitted at Asan Medical Center between January 2006 and February 2017. The 416 patients under 18 months of age were enrolled as subjects for the analysis of the association between BCG site reaction and other laboratory and clinical findings. The analysis was performed separately in complete and incomplete KD groups. Results: The incidence rate of BCG site reaction was peaked at 6-12 months (83%) and decreased with increasing age after 12 months in 1,058 patients (P<0.001). The incidence rate was above 70% in KD aged less than 18 months and more frequent than those of cervical lymphadenopathy. The logistic regression analyses showed that the principal clinical findings including conjunctivitis (P=0.781), red lips/oral mucosa (P=0.963), rash (P=0.510), cervical lymphadenopathy (P=0.363), changes in extremities (P=0.283) and the coronary artery aneurysm (P=0.776) were not associated with the BCG site reaction. Conclusions: The BCG site reaction could be a useful diagnostic tool independent to principal clinical findings in KD developing in children aged <18 months, who underwent BCG vaccination. Outcome of KD patients was not different between groups with or without the BCG site reaction in both complete KD and incomplete KD.

Vibrio vulnificus cytolysin (VVC) forms a pore in the plasma membrane and induces cytolysis of various cells including erythrocytes, neutrophil and endothelial cells. The cytolytic activity of VVC is inhibited by exogenously added cholesterol, suggesting that membrane cholesterol might be required for VVC cytolytic activity. However, there is no direct evidence that membrane cholesterol is involved in VVC-induced cytolysis. Herein we demonstrate that membrane cholesterol is required for binding of VVC to the plasma membrane. Membrane cholesterol depletion with methyl-β-cyclodextrin inhibited VVC-induced K^(+) release, 2-deoxy glucose release and Ca^(2+) influx, which are indicators of VVC pore formation. The cholesterol depletion-induced blockage of VVC cytolysis was due to the inhibition of VVC binding to membrane. These findings suggest that interaction with cholesterol is required for activity of VVC.

Purpose: To evaluate the efficacy of focal verteporfin photodynamic therapy (PDT) in patients diagnosed with chronic central serous chorioretinopathy (CSC). Methods: This study enrolled 52 eyes of 52 patients with chronic CSC who had received verteporfin PDT. The laser spot size of 26 eyes covering only the localized hyperfluorescent area in indocyanine green angiography was classified as focal PDT. The PDT spot size of the other 26 eyes covered the total area of retinal pigment epithelial detachment including the leaking point and was defined as conventional PDT. The central subfield thickness and subfoveal choroidal thickness were measured using Heidelberg Spectralis optical coherence tomography before PDT and at months 1, 3, 6, and 12 after PDT. Results: The mean spot size of the PDT was 1,995 μm in the focal group and 2,995 μm in the conventional group. Central subfield thickness steadily decreased in both groups. The mean baseline subfoveal choroidal thickness for the two groups was 334.95 and 348.35 μm, respectively, with no significant difference (p = 0.602). Subfoveal choroidal thickness decreased significantly to 304.20 μm at 1 month, 284.85 μm at 3 months, 271.60 μm at 6 months, and 265.95 μm at 12 months in the focal group (p < 0.001, p < 0.001, p < 0.001, and p < 0.001, respectively, compared with baseline). In the conventional group, subfoveal choroidal thickness decreased significantly to 318.75, 300, 284, and 272 μm at 1, 3, 6, and 12 months, respectively (p < 0.001, p < 0.001, p < 0.001 and p < 0.001 compared with baseline). There were no significant differences between the two groups in subfoveal choroidal thickness based on PDT spot size at 1, 3, 6, and 12 months (p = 0.633, p = 0.625, p = 0.676, and p =0.755, respectively). Conclusions: Focal verteporfin PDT for CSC significantly decreased the subretinal fluid and sufoveal choroidal thickness to the same extent as conventional PDT.

PURPOSE. Fracture of the veneering material of zirconia restorations frequently occurs in clinical situations. The purpose of this in vitro study was to compare the fracture strengths of zirconia crowns veneered with various ceramic materials by various techniques. MATERIALS AND METHODS. A 1.2 mm, 360º chamfer preparation and occlusal reduction of 2 mm were performed on a first mandibular molar, and 45 model dies were fabricated in a titanium alloy by CAD/CAM system. Forty-five zirconia copings were fabricated and divided into three groups. In the first group (LT) zirconia copings were veneered with feldspathic porcelain by the layering technique. In the second group (HT) the glass ceramic was heat-pressed on the zirconia coping, and for the third group (ST) a CAD/CAM-fabricated high-strength anatomically shaped veneering cap was sintered onto the zirconia coping. All crowns were cemented onto their titanium dies with Rely XTM Unicem (3M ESPE) and loaded with a universal testing machine (Instron 5583) until failure. The mean fracture values were compared by an one-way ANOVA and a multiple comparison post-hoc test (alpha= 0.05). Scanning electron microscope was used to investigate the fractured interface. RESULTS. Mean fracture load and standard deviation was 4263.8+/-1110.8 N for Group LT, 5070.8+/-1016.4 for Group HT and 6242.0+/-1759.5 N for Group ST. The values of Group ST were significantly higher than those of the other groups. CONCLUSION. Zirconia crowns veneered with CAD/CAM generated glass ceramics by the sintering technique are superior to those veneered with feldspathic porcelain by the layering technique or veneered with glass ceramics by the heat-pressing technique in terms of fracture strength.
