Fractures of the lateral process of the talus (LPT) are considered rare, accounting for less than 1% of all ankle injuries in the general population. These fractures are nearly 15 times more likely to occur in snowboarders. Recently, the number of population who started enjoying cable-wakeboard is increasing and this sport may cause fracture of the LPT by axial loading occur on the LPT while boarding or trick. We report on a case of involving LPT fracture during cable-wakeboard trick with successful screw osteosynthesis.

Kimura's disease is a chronic inflammatory soft tissue disorder with peripheral eosinophila and high serum IgE. It might be associated with nephrotic syndrome. We report a 6-year-old boy with Kimura's disease and the concurrent steroid dependant minimal change nephrotic syndrome. With levamisole treatment fot 24 months, tumor progression and relapse of the associated nephrotic syndrome were not observed.

Ketosis-prone diabetes includes heterogeneous disease groups characterized by provoked or unprovoked ketoacidosis (ketosis), with a typical phenotype of autoimmune type 1 diabetes. As the incidence of obesity and type 2 diabetes is universally increasing, the rate of type 2 diabetes in diabetic ketoacidosis in children and adolescents is exptected to increase rapidly. The clinical presentation of atypical ketoacidosis with type 2 diabetes has been reported mostly in adults. We recently experienced a case of a 10-year-old obese girl with new-onset type 2 diabetes who initially presented with severe diabetic ketoacidosis, and introduce it with literature reviews.

5.Medical Augmented Reality and Virtual Reality
Journal of the Korean Radiological Society 2019;80(2):226-238
Augmented reality (AR) or virtual reality is used in many fields, including medicine, education, manufacturing, and entertainment. With technical advances in optics, computer systems, and surgical instruments, AR applications to medicine are being vigorously researched. In particular, as surgeries using laparoscopy, endoscopy, or catheterized intervention have increased, AR plays an important role in many medical applications. AR is defined as a technique to combine the real world and virtual objects, which are digital content artificially generated by a computer. As another aspect of AR is the registration between the real world and virtual objects, it aims at an accurate estimation of the three-dimensional (3D) position and orientation of virtual objects related to the real world. Essentially, AR can allow users to see 3D virtual objects superimposed upon the real world. With the help of AR, a surgeon can view invisible organs during the surgery and improve the accuracy and safety of treatment procedures. After a brief description of the technical issues of medical AR, its applications will be introduced in this article.

Hanyang Medical Reviews 2016;36(4):242-247
Augmented reality is popular in various fields, and the importance of this technology has been increasing. Its medical application has also been widely studied. Particularly, augmented reality can be a more promising technique of a surgery which requires great precision. This paper introduces an overview of augmented reality and reviews the recent applications in medicine. After describing the basic concepts, brief characteristics of the three components that comprise augmented reality are provided. Various applications implemented in the authors' laboratory are reviewed.

PURPOSE: The degree of radiation-induced lung fibrosis (RILF) can be measured quantitatively by fibrosis volume (VF) on chest computed tomography (CT) scan. The purpose of this study was to investigate the interobserver and intraobserver variability in CT-based measurement of VF. MATERIALS AND METHODS: We selected 10 non-small cell lung cancer patients developed with RILF after postoperative radiation therapy (PORT) and delineated VF on the follow-up chest CT scanned at more than 6 months after radiotherapy. Three radiation oncologists independently delineated VF to investigate the interobserver variability. Three times of delineation of VF was performed by two radiation oncologists for the analysis of intraobserver variability. We analysed the concordance index (CI) and inter/intraclass correlation coefficient (ICC). RESULTS: The median CI was 0.61 (range, 0.44 to 0.68) for interobserver variability and the median CIs for intraobserver variability were 0.69 (range, 0.65 to 0.79) and 0.61(range, 0.55 to 0.65) by two observers. The ICC for interobserver variability was 0.974 (p < 0.001) and ICCs for intraobserver variability were 0.996 (p < 0.001) and 0.991 (p < 0.001), respectively. CONCLUSION: CT-based measurement of VF with patients who received PORT was a highly consistent and reproducible quantitative method between and within observers.

9.Network Analysis in Systems Epidemiology

Journal of Preventive Medicine and Public Health 2021;54(4):259-564
Traditional epidemiological studies have identified a number of risk factors for various diseases using regression-based methods that examine the association between an exposure and an outcome (i.e., one-to-one correspondences). One of the major limitations of this approach is the “black-box” aspect of the analysis, in the sense that this approach cannot fully explain complex relationships such as biological pathways. With high-throughput data in current epidemiology, comprehensive analyses are needed. The network approach can help to integrate multi-omics data, visualize their interactions or relationships, and make inferences in the context of biological mechanisms. This review aims to introduce network analysis for systems epidemiology, its procedures, and how to interpret its findings.
