  • Many recent studies have reported that the quality of input learning data was vital to the detection of regions of interest. However, due to a lack of research on the quality of learning data on lesion detetcting using gastroscopy, we aimed to quantify the impact of quality difference in endoscopic images to lesion detection models using Image Quality Assessment (IQA) algorithms. Through IQA methods such as BRISQUE (Blind/Referenceless Image Spatial Quality Evaluation), Laplacian Score, and PSNR (Peak Signal-To-Noise) algorithm on 430 sheets of high quality data (HQD) and 430 sheets of low quality data (PQD), we showed that there were significant differences between high and low quality images in lesion detecting through BRISQUE and Laplacian scores (p<0.05). The PSNR value showed 10.62±1.76 dB on average, illustrating the lower lesion detection performance of PQD than HQD. In addition, F1-Score of HQD showed higher detection performance at 77.42±3.36% while F1-Score of PQD showed 66.82±9.07%. Through this study, we hope to contribute to future gastroscopy lesion detection assistance systems that involve IQA algorithms by emphasizing the importance of using high quality data over lower quality data.

  • Objectives The purpose of this study is to analyze the characteristic of the 157 pediatric patients who visited a Korean medical hospital for bone age (BA) measurement and to compare the BA measurement using Tanner-Whitehouse 3-based analysis software and specialists in pediatric Korean medicine to determine the relationships. Methods The study included 157 pediatric patients who visited a Korean medicine hospital for BA measurements from June 2021 to June 2023. They were analyzed to determine the characteristics and agreement of BA measurements using Tanner-Whitehouse 3-based analysis software and specialists using classification by age, intraclass correlation coefficient (ICC), and Bland-Altman plots. Results In total, 61.8% of the study population were boys and 38.2%, girls, with an average age of 11.32 ± 1.87. The types of growth were various, and the average of bone maturity was 0.48 ± 1.13 as concluded by analysis software and 0.38 ± 1.15 as concluded by the specialists. The ICC of two methods were excellent: 0.995 (overall), 0.996 (boys) and 0.994 (girls). However, BA determined by analysis software tended to be higher than that determined by specialists when the patients were young. Conclusions This study showed that patients visited the hospital for BA measurement regardless of their height, and the agreement of BA between the two methods can be used as a reference. However, there was differences in the trends between age and sex, which should be interpreted with caution.

  • 목적: 2017년 지하수를 식수로 사용하고 있는 한 장기요양 정신병원(H병원)에서 A형간염 환자가 집단 발병하여 이에 대한 역학조사를 실시하고 조치 결과를 기술하고자 하였다. 방법: 노출기간 동안 H병원의 근로자 및 재원 환자 234명을 대상으로 사례군 조사 디자인으로 역학조사를 실시하였고, IgM, IgG 혈청검사 및 A형간염 바이러스(HAV)에 대한 PCR검사를 시행하였다. 또한 오염원으로 의심되는 지하수, 병원에서 제공되는 식품 및 인근 저수지의 물에서 HAV 검사를 실시하였고, 검출된 HAV는 유전형 검사를 진행하였다. 결과: H병원 환자 및 직원 234명 중 IgG 양성인 168명을 제외한 66명 중 19명이 최종적으로HAV 감염자로 확인되어 감수성자 중 발병률은 28.8%로 나타났다. 환자, 지하수, 식품(석박지) 및 저수지에서 동일 유전형의 HAV가 검출되어 지하수 오염에 의한 집단발병으로 결론 내렸으나, 최초 오염원은 확인하지 못하였다. 유행 종결 선언 이후 지하수에 대한 관리로 염소소독과 UV 조사를 하였음에도 불구하고 6개월 동안 지속적으로 HAV가 검출되어 새로운 관정을 개발하여 상황을 종결하였다. 결론: 본 연구에서 지하수를 식수로 사용하는 장기요양 정신병원에서 지하수 오염에 의한 19명의 HAV 집단발병을 조사하였다. HAV 항체가 없는 대상자 중에서 HAV의 높은 발병률을 확인하였다. 지하수 수질검사에서 바이러스 검사는 포함되어 있지 않기 때문에 지하수가 HAV에 오염시 HAV 집단발병 가능성이 높고 상당기간 지속적으로 검출되기 때문에 지하수에 대한 관리지침에 바이러스 검출을 위한 방안을 추가하고 관련 법을 정비할 필요가 있다.

  • Objectives : It has been shown that early intervention is crucial for favorable outcome in patients with schizophrenia. However, development of biomarkers for predicting prognosis of psychotic disorder still requires more research. In this study, we aimed to investigate whether baseline mismatch negativity (MMN) predict prognosis in patients with first episode psychosis (FEP). Methods : Twenty-four patients with FEP and matched healthy controls (HCs) were examined with MMN at baseline, and their clinical status were re-assessed after 1 year. Repeated-measures analysis of variance was performed to compare baseline MMN between the two groups. Multiple regression analysis was used to identify factors predicting prognosis in FEP patients during the follow-up period. Results : MMN amplitudes at baseline were significantly reduced in patients with FEP compared to healthy controls. In the multiple regression analysis, baseline MMN amplitude significantly predicted later improvement of performances on digit span and delayed recall of California Verbal Learning Test. However, baseline MMN did not predicted improvement of clinical symptoms. Conclusion : These results indicate that MMN may be a possible predictor of improvement in cognitive functioning in patients with FEP. Future study with larger sample and longer follow-up period would be needed to confirm the findings of the current study.

  • Objectives : The purpose of this study is to analyze the oriental medical treatments of burning mouth syndrome, understand the tendency of treatment, and apply it to clinical settings. Methods : We collected case reports, retrospective cohort studies and RCT studies related to oriental medical treatments of burning mouth syndrome using domestic and Chinese databases(CNKI, KISS, RISS, OASIS, KCI). Search terms include 'Burning Mouth Syndrome', 'BMS', 'Burning Tongue', '灼口综合征', and 'oriental medicine', 'oriental medical treatment', 'Korean medicine' and '中医'. A search was conducted by appropriately combining keywords. Results : A total of 27 papers were included in the analysis. Among them, 9 are case studies, 1 is a retrospective cohort study, 1 is a before and after study and 16 are RCT studies. Treatments for burning mouth syndrome included herbal medicine, acupuncture, electro-acupuncture, acupoint injection, auricular acupuncture treatment, external use herbal medicine and gargling. In all studies, symptoms of burning mouth syndrome were alleviated after oriental medical treatments. In 14 RCT studies comparing western medical treatments, the results of the treatment group that included oriental medical treatments were found to be more significant, except for one. Conclusions : As a result of the study, oriental medical treatments are effective in treating burning mouth syndrome. In the future, we hope that clinical research related to oriental medical treatments of burning mouth syndrome will be actively conducted so that evidence-based treatment can be implemented.
