Background: Radial probe endobronchial ultrasound (R-EBUS), is effective for tissue diagnosis of lung lesions. We evaluated the diagnostic performance of R-EBUS both a guide-sheath and fluoroscopy and identified factors associated with accurate diagnosis. The feasibility of molecular and genetic testing, using specimens obtained by R-EBUS, was also investigated. Methods: The study retrospectively reviewed 211 patients undergoing R-EBUS without a guide-sheath and fluoroscopy, June 2016-May 2017. After excluding 27 patients of which the target lesion was not reached, 184 were finally included. Multivariate logistic regression was used, to identify factors associated with accurate diagnosis. Results: Among 184 patients, R-EBUS-guided biopsy diagnosed malignancy in 109 patients (59%). The remaining 75 patients (41%) with non-malignant results underwent additional work-ups, and 34 were diagnosed with malignancy. Based on final diagnosis, diagnostic accuracy was 80% (136/170), and sensitivity and specificity for malignancy were 76% (109/143) and 100% (27/27), respectively. In multivariate analysis, peripheral location (adjusted odds ratio [aOR], 3.925; 95% confidence interval [CI], 1.203-12.811; p=0.023), and central position of the probe (aOR, 2.435; 95% CI, 1.424-7.013; p=0.035), were associated with accurate diagnosis of malignancy. Molecular and genetic analyses were successful, in all but one case, with inadequate specimens. Conclusion: R-EBUS-guided biopsy without equipment, is effective for tissue diagnosis. Peripheral location and central position of the radial probe, were crucial for accurate diagnosis. Performance of molecular and genetic testing, using samples obtained by R-EBUS, was satisfactory.

Research purpose : Review of the systematized medical theory of Huangdi within the first series of conversations including questions and answers between Leigong and Huangdi. Conclusions : 1. "Huang-di-Nei-Jing" records the 5 theories of Huangdi's system of thinking (黃帝學派). Among these, the contents of the questions and answers with Leigong led to the establishment of the first of Huangdi's treatises. 2. In the questions and answers exchanged between Leigong and Huangdi, the Suwen (素問) Chapter deals with the areas of Yinyang, Zangfu, Cause and Mechanism of diseases, as well as medical ethics. Moreover, the "Lingshu (靈樞)" Chapter discusses distribution of meridian system, routes of circulation of energies, symptoms, acupuncture therapy and diagnosis, etc. 3. Characteristics of the medicine of Leigong and Huangdi can be summarized as follows: Firstly, 12 meridian systems of the "Jingmai (經脈)" section describes the meridian system that ceaselessly circulates in the shape of loops with the inner and outer aspects linked with each other. Secondly, regarding the methods of diagnosis, the "Yinyangleilun (陰陽類論)" section describes the method of diagnosis through palpation of pulse. In addition, the "Wuse (五色)" section describes visual diagnosis that uses five colors. The Wuhang combination of spleen, liver, kidney of "Shicongronglun (示從容論)" section also includes the Wuhang theory of "Jinwenshangshu (今文尙書)". The "Wuse" section discusses areas of the face and five colors, while the "Yinyangleilun" discusses the 'Yinyancixiongmaifa (陰陽雌雄脈法)', the "Jingmai" discusses the 'Yinyancunkoumaifa (人迎寸口脈法)', and the "Zhengsishilun" and "Fangchengshuailun" discuss 'chifuzhenfa (尺膚診法)'. Thirdly, Huangdi's school of thinking did not neglect bencao (本草) and tangye (湯液), which are discussed in the "Jiejingweilun" and "Shicongronglun" sections.

There are two reasons that the remote medical is newly embossed. One is the development of the info-communications technology that is possible to the remote diagnosis. Another is changing the thinking about the new medical services for the offerers and consumers. Therefore, we suggest the mobile-environmental remote diagnosis system. The system could apply more efficient connection with the very fast developing diagnosis and medical treatment.

Hemolytic anemia and thrombocytopenia are rare clinical manifestations of acute glomerulonephritis. Initially, in all such cases, a diagnosis of hemolytic uremic syndrome, thrombotic thrombocytopenic purpura, systemic lupus erythematosus, and amyloidosis should be ruled out. The presence of hemolytic anemia and thrombocytopenia is rare, but possible, in a case of acute poststreptococcal glomerulonephritis, and may result in delayed diagnosis or misdiagnosis. Correct and timely diagnosis would ensure adequate treatment in such patients. We report of a 22-month-old boy with acute glomerulonephritis coexistent with hemolytic anemia and idiopathic thrombocytopenia.

The Center for Imaging Human Structures (CIH) was established in December 2002 to develop new diagnostic imaging techniques and to make them available to the greater community of biomedical and clinical researchers at Sungkyunkwan University. CIH has been involved in 5 specific activities to provide solutions for early diagnosis and improved treatment of human diseases. The five area goals include: 1) development of a digital mammography system with computer aided diagnosis (CAD); 2) development of digital radiological imaging techniques; 3) development of unified medical solutions using 3D image fusion; 4) development of multi-purpose digital endoscopy; and, 5) evaluation of new imaging systems for clinical application

Recently, the digital healthcare technologies including non-invasive diagnostics based on Internet of Things (IOT) are getting attention. Human exhaled breath contains a variety of volatile organic compounds (VOCs), which can provide information of malfunctions of the body and presence of a specific disease. Detection of VOCs in exhaled breath using gas sensors are easy to use, safe, and cost-effective. However, accurate diagnosis of diseases is challenging because changes in concentration of VOCs are extremely small and lots of body factors directly or indirectly influence to the conditions. To overcome the limitations, highly selective nanosensors and artificial intelligent electronic nose (E-nose) systems have been mainly researched in recent decades. This review provides brief reviews of the recent studies for diabetes and lung cancer diagnosis using nanosensors and E-nose systems.

In Korean medicine, tongue diagnosis is one of the important diagnostic methods for diagnosing abnormalities in the body. Representative features that are used in the tongue diagnosis include color, shape, texture, cracks, and tooth marks. When diagnosing a patient through these features, the diagnosis criteria may be different for each oriental medical doctor, and even the same person may have different diagnosis results depending on time and work environment. In order to overcome this problem, recent studies to automate and standardize tongue diagnosis using machine learning are continuing and the basic process of such a machine learning-based tongue diagnosis system is tongue segmentation. In this paper, image data is augmented based on the main tongue features, and backbones of various famous deep learning architecture models are used for automatic tongue segmentation. The experimental results show that the proposed augmentation technique improves the accuracy of tongue segmentation, and that automatic tongue segmentation can be performed with a high accuracy of 99.12%.
