S-295 ST 분절의 상승이 없는 심근경색증 환자들의 임상결과
황재준,박창범 대한내과학회 2016 대한내과학회 추계학술대회 Vol.2016 No.1
배경: ST 분절 상승을 동반하지 않는 심근경색 환자(NSTEMI)의 심전도(ECG)는 다양하게 나타난다. 방법 : 2006년 부터 2013년 까지 본원에 입원하여 관상동맥조영술(coronary angiogram)을 시행받은 345명의 NSTEMI 환자의 인구통계학, 시술특성, 임상결과를 분석하였다. 결과 : 심전도상에서 ST 분절 하강군은 114 명, T-wave inversion 군은 90 명, 변화가 없는 군은 141 명이었다. ST 분절 하강 군은 변화가 없은 군에 비해 나이가 더 많았으며 비흡연자이고 신체질량지수(BMI)가 적게 나가는 여성, 공존질환이 더 많은 양상을 보였다. 또한 높은 Killip class, 낮은 좌심실 구혈률(left ventricular ejection fraction), 높은 벽운동지수(regional wall motion score index), 혈관조영술 상에서 혈관 근위부, 3개 혈관질환(3-vessel coronary artery disease) 발생 비율이 더 높았다. 반면 T-wave inversion 군은 변화가 없는 군과 비슷한 양상을 보였다. 임상결과에서는 심전도상에서 변화가 없었던 군에 비해 ST분절 하강군이 시술 후 30일, 12개월 사망율이 더 높았던 반면 T-wave inversion군은 비슷한 양상을 보였다. 결론: 심전도상에서 변화가 없었던 군에 비해 ST분절 하강군은 공존질환이 더 많았으며 원내 및 12개월 사망율이 더 높았으나 T-wave inversion 군은 비슷한 양상을 보임을 확인할 수 있었다.

In pulmonary arteriovenous fistula, there are abnormal communications between the pulmonary arteries and the pulmonary veins; the capillary networks that normally separate arteries from veins is absent. The only available treatment of this uncommon variety is an excision. We report a case of pulmonary arteriovenous fistula cured by segmentectomy with a review of literatures.
Epidemiology of Antiphospholipid Syndrome in Korea: a Nationwide Population-based Study
황재준,Seo-Hee Shin,김예지,오연목,Sang Do Lee,김이형,Cheon Woong Choi,Jae Seung Lee 대한의학회 2020 Journal of Korean medical science Vol.35 No.5
Background: Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by arterial and venous thrombosis or pregnancy morbidity in patients with persistent antiphospholipid antibodies. However, nationwide population-based epidemiology studies regarding APS are still unavailable. Methods: We analyzed claims data extracted from the Korean Health Insurance and Review Agency (HIRA) covering more than 52 million Koreans, between January 1, 2008, and December 31, 2017. Patients diagnosed with APS, as determined by the Korean Classification of Disease, 7th edition (D68.6), and a rare intractable disease program (V253), were identified in HIRA. Results: A total of 3,088 newly diagnosed incident cases of 1,215 men and 1,873 women were identified during 2009–2016. The mean age was 44.6 ± 16.6 (men, 47.4 ± 16.3; women, 42.8 ± 16.6) years. The incidence was 0.75 per 105 person-year (95% confidence interval, 0.73–0.78). The prevalence in 2016 was 6.19 per 105 people. For incident cases, women showed incidence peak at ages of 30–39 years and 70–79 years, whereas for men, it was highest at ages of 70–79 years only. Of all patients, 1,766 (57%, 810 men and 956 women) had primary APS, 1,322 (43%, 405 men and 917 women) had secondary APS, and 845 (27%, 216 men and 629 women) were associated with systemic lupus erythematosus (SLE). Conclusion: The incidence of APS differs according to age groups and gender. The incidence of primary APS was higher than that of secondary APS in both gender. Furthermore, as already reported, secondary APS is highly associated with SLE; however, we observed that rheumatoid arthritis is also highly related.

폐실질 내 과오종은 흔히 볼 수 있는 양성 폐종양이나, 기관지 내 과오종은 드문 종양 중 하나이다. 치료로는 기관지내시경을 이용한 제거나 기관절개 또는 정상적인 폐실질을 보존하기 위해 소매절제를 통한 종양의 제거가 보편적이다. 그러나 만성적인 기관지 폐쇄로 인해 폐실질이 파괴되어 보존이 어려운 경우에는 폐절제술이 필요할 수 있다. 저자는 기관지 내 과오종에 의해 좌상엽의 경화가 진행되어 좌상엽절제술이 필요했던 환자를 보고하는 바이다. 42세 여자가 3주일 전부터 발생한 기침과 좌측 흉통을 주소로 내원하였다. 기관지내시경 소견상 좌상엽기관지의 입구를 완전히 막고 있는 엽성 종괴가 관찰되었고, 생검을 시도하였으나 출혈로 실패하였다. 수술 소견상 만성적인 기관지 폐쇄에 의해 좌상엽의 경화가 심하여 좌상엽절제술을 시행하였다. 환자는 술 후 14일째 퇴원하였다.
An overview of deep learning in the field of dentistry
황재준,정연화,조봉혜,허민석 대한영상치의학회 2019 Imaging Science in Dentistry Vol.49 No.1
Purpose: Artificial intelligence (AI), represented by deep learning, can be used for real-life problems and is applied across all sectors of society including medical and dental field. The purpose of this study is to review articles about deep learning that were applied to the field of oral and maxillofacial radiology. Materials and Methods: A systematic review was performed using Pubmed, Scopus, and IEEE explore databases to identify articles using deep learning in English literature. The variables from 25 articles included network architecture, number of training data, evaluation result, pros and cons, study object and imaging modality. Results: Convolutional Neural network (CNN) was used as a main network component. The number of published paper and training datasets tended to increase, dealing with various field of dentistry. Conclusion: Dental public datasets need to be constructed and data standardization is necessary for clinical application of deep learning in dental field.

Background: Acute exacerbation of chronic obstructive pulmonary disease(AECOPD) patients with high uric acid (UA) level, have been reported to show a high mortality rate. However, there is no study of stable COPD patients regarding UA levels. Methods: 286 COPD patients from the Korean Obstructive Lung Disease (KOLD) cohort with baseline UA measurement was included. The optimal cutoff value of UA was determined from the ROC curve and COX analysis was used for mortality risk evaluation. Results: The optimal cutoff value was 6.2 mg/dL (AUC: 0.587, 0.507-0.666, P<0.001) and was divided into two groups (high UA group, n=110 vs low UA group, n=176). Baseline characteristics differed only in BMI (low UA, 22.3±3.0 vs. High UA 23.8±2.9, P<0.001). In the univariate Cox analysis of overall mortality, HR was significantly lower in the high UA group (HR 0.36, 95% CI=0.18-0.71, P=0.003) and Kaplan-Meier plots showed survival benefit (P<0.002). In multivariate Cox analysis, however, only age (HR 1.11, P<0.001), FEV1 (HR 0.97, P=0.022) and BMI (HR 0.81, P<0.001) were found to be significant. In multivariate Cox analysis, UA(HR 0.707, 95% CI=0.34-1.47, P=0.352) was statistically insignificant. However, as a predictive biomarker of mortality, stable COPD patients showed a tendency opposite to that of AECOPD patients. Conclusions: UA is a flexible biomarker that can be altered by various factors as well as the degree of inflammation and nutritional status of the patient. Further study is needed in consideration of the low baseline BMI in the low UA group.
