Purpose: To report the clinical course with optical coherence tomography findings following intravitreal bevacizumab injection in patients with posterior placoid chorioretinitis due to latent syphilis. Case summary: A 43-year-old woman presented with visual dimness in the right eye 3 days in duration. Fundus examination showed yellow, placoid lesions in the right eye and there was no cell reaction in the anterior chamber and vitreous. An intravitreal bevacizumab injection was given and systemic work-up performed. After 1 week, the macular lesion disappeared. However, photoreceptor disarrangement was present on spectral-domain optical coherence tomography image. On serologic test, the Venereal Disease Research Laboratory test, and fluorescent treponemal antigen absorption test were positive. She was referred to a division of infectious diseases and confirmed as latent syphilis. The patient received intramuscular penicillin 3 times weekly. Visual acuity and outer retinal abnormality further improved and there was no recurrence during the 6-month follow-up. Conclusions: Intravitreal bevacizumab injection added to antibiotic treatment may be considered for treating patients with posterior placoid chorioretinitis. Further studies are necessary to evaluate precise disease mechanisms and treatment.

한세훈(Se Hun Han),황호식(Ho Sik Hwang),신민철(Min Chul Shin),한경은(Kyung Eun Han) 대한안과학회 2015 대한안과학회지 Vol.56 No.5
목적: Galilei™ (Ziemer, Port, Switzerland)와 Pentacam?? (Oculus, Wetzlar, Germany), Lenstar?? (Haag-Streit, Koeniz, Switzerland)로 측정한 중심각막두께와 전방깊이의 측정치를 비교하고, 일치도를 분석하고자 한다. 대상과 방법: 정상 성인 25명의 47안을 대상으로 세 기기를 이용하여 측정한 중심각막두께와 전방깊이를 비교하였다. 결과: Galilei™, Pentacam??, Lenstar?潁? 이용하여 측정한 중심각막두께는 각각 552.6 ± 29.41 μm, 543.9 ± 30.50 μm, 537.5 ±30.26 μm였고, 측정치 간에 높은 상관관계를 보였으나(r>0.9, p<0.001), 통계적으로 유의한 차이를 보였다(p<0.001). 전방깊이는 Galilei™가 3.23 ± 0.360 mm, Pentacam?瑛? 3.22 ± 0.403 mm, Lenstar?怜? 3.19 ± 0.367 mm였고, 측정치 간에 높은 상관관계를 보였으나(r>0.9, p<0.001), 통계적으로 유의한 차이를 보였다(p=0.034). 95% 일치도 범위는 Galilei™와 Pentacam??, Pentacam?怜? Lenstar??, Lenstar?玲? Galilei™ 사이에서 중심각막두께는 31.95 μm, 44.76 μm, 46.57 μm, 전방깊이는 0.46 mm, 0.32 mm, 0.28 mm였다. 결론: 세 기기로 측정한 중심각막두께 및 전방깊이는 상관성이 높으나, 측정값에 차이를 보이고 일치도가 낮아 서로 대치하여 사용할 수 없을 것으로 생각한다. <대한안과학회지 2015;56(5):694-701> Purpose: To compare measurements of central corneal thickness (CCT) and anterior chamber depth (ACD) obtained using Galilei™, Pentacam?? (Oculus, Wetzlar, Germany) and Lenstar?? (Haag-Streit, Koeniz, Switzerland) and analyze the measure-ment agreements. Methods: CCT and ACD were measured using Galilei™, Pentacam?? and Lenstar?? in 47 eyes of 25 healthy subjects. The meas-urements were compared among the 3 devices. Results: The average CCT measurements using Galilei™, Pentacam?? and Lenstar?? were 552.6 ± 29.41 μm, 543.9 ± 30.50 μm and 537.5 ± 30.26 μm, respectively. The measurements significantly correlated with each other (r > 0.9, p < 0.001), but were stat-istically significantly different (p < 0.001). The average ACD measurements using Galilei™, Pentacam?? and Lenstar?? were 3.23 ± 0.360 mm, 3.22 ± 0.403 mm and 3.19 ± 0.367 mm, respectively. The measurements significantly correlated with each other (r > 0.9, p < 0.001), but were statistically significantly different (p = 0.034). The CCT 95% limits of agreement (LoA) between Galilei™ and Pentacam??, Pentacam?? and Lenstar?? and Lenstar?? and Galilei™ were 31.95 μm, 44.76 μm and 46.57 μm, respectively and 95% ACD LoA were 0.46 mm, 0.32 mm and 0.28 mm, respectively. Conclusions: CCT and ACD measured using the 3 devices were highly correlated with each other but the measurements were statistically different. Therefore, the measurements were not interchangeable and these differences should be considered in clin-ical use. J Korean Ophthalmol Soc 2015;56(5):694-701

본 연구에서는 2021년 3월 4일 19:07경 울산 온산사거리 인근 하천에서 발생한 원유이송배관 파공으로 인한 원유 유출사고 관련 시료 감식 사례를 통해 원유(Crude Oil) 특성을 알아보고자 한다. 연구방법은 GC-FID 및 GC-MS를 활용한 유럽표준분석기법(CEN methodology)를 적용하여 원유 유출사고 시료 총 2점과 아라비안라이트(Arabian Light) 원유 샘플을 감식·분석하였다. GC-FID에 의한 포화탄화수소 비교 결과, 연구 대상 시료 모두 포화탄화수소 <sub>8<sub> ~ <sub>36</sub>가 검출되었고, 해상유출유와 비교시료의 포화탄화수소 피크 패턴 및 UCM(Unresolved Complex Mixture)의 형태, 풍화도 그래프(GC-PW-Plot), 판별지수 비교하여 모두 유사기준 이내임을 확인하였다. (그림-1) GC-MS에 의한 Biomarker 및 다환방향족탄화수소류(PAHs) 비교 결과, 물질 별 크로마토그램이 일치하며, 풍화도 그래프(MS-PW-plot), 판별지수(Diagnostic Ratios)도 유사기준 이내임을 확인하였고, C1-phenanthrenes(m/z 192)에서 MA(Methyl Antracene) 미검출 등 원유의 전형적인 특징과 황(Sulfur) 관련 PAHs인 C1-Dibenzothiophenes (m/z 198), C2-Dibenzothiphenes(m/z 212) 등이 높게 검출되어 고유황 원유임을 확인하였다. (그림-2) 최근 발생한 원유 유출사고 관련 시료를 유럽표준분석기법을 통해 감식·분석하여 원유의 특성 파악하고, 기존 보유중인 원유 샘플과도 비교하였다. 이는 앞으로 발생할 수 있는 원유유출사고에 대한 데이터베이스 축적 및 활용을 기대해본다. In this research, We want to find out the characteristics of crude oil through the sample identification related to the oil spill caused by the oil transfer pipe hole occurred in a river near Onsan Intersection in Ulsan on March 4, 2021 at 19:07. The methodology was applied with CEN methodology using GC-FID and GC-MS to identify two samples taken during the oil spill and Arabian Light samples. A comparison results of saturated hydrocarbons by GC-FID, All samples in the study are detected with saturated hydrocarbon <sub>8<sub> ~ <sub>36</sub>, and a comparison of the peak patterns of saturated hydrocarbon, UCM(Unresolved Complex Mixture), GC-PW-plot and Diagnostic Ratios on the Spill oil and comparison samples confirmed that they are all within similar criteria. (picture-1) A comparison results of Biomarker and PAHs by GC-MS, the chromatograms of each compounds are matched in the visual comparison, MS-PW-plot and Diagnostic also confirmed that they are all within similar criteria. Also, We identify typical characteristics of Crude Oil that MA(Methyl Antracene) is not detected in C1-phenanthrenes(m/z 192), and PAHs that related to Sulfur such as C1-Dibenzothiophenes(m/z 198) and C2-Dibenzothiphenes(m/z 212) are detected high. So it is means that they are high sulfur crude oil. (picture-2) We identify the characteristics of crude oil that spilled recently using CEN methodology and compare with existing crude oil. This is expected to accumulate and utilize databases for future spill crude oil.
