Artificial intelligence (AI) refers to the use of machines to mimic intelligent human behavior. It involves interactions with humans in clinical settings, and augmented intelligence is considered as a cognitive extension of AI. The importance of AI in healthcare and medicine has been emphasized in recent studies. Machine learning models, such as genetic algorithms, artificial neural networks (ANNs), and fuzzy logic, can learn and examine data to execute various functions. Among them, ANN is the most popular model for diagnosis based on image data. AI is rapidly becoming an adjunct to healthcare professionals and is expected to be human-independent in the near future. The introduction of AI to the diagnosis and treatment of oral diseases worldwide remains in the preliminary stage. AI-based or assisted diagnosis and decision-making will increase the accuracy of the diagnosis and render treatment more precise and personalized. Therefore, dental professionals must actively initiate and lead the development of AI, even if they are unfamiliar with it.

We examined clinical and reseach data about abdominal palpation conducted in japanese oriental medicine from the early stages of its medical history to the latest research, so as to introduce it into korean oriental medicine. That is to say, we studied clinical significance and suitable oriental medicine prescription about following : sweat and moistness of abdominal skin ; temperature of abdominal skin ; palpation and visible peristaltic movement ; meteorism ; tonus of the whole rectus abdominis muscle ; local tonus of parts rectus abdominis muscle ; palpitation of abdominal aorta ; resistance tender on pressure in epigastric region, subcostal region, umbilical region, lower abdomen, para-umbilical region, cecal region, sigmoid region and inguinal region ; sound of fluctuating liquid in the epigastric region. The result was that abdominal palpation was an immediately applicable method of clinical diagnosis in oriental medicine, and is being proven by western medicine methodology today. Therefore we suggest that korean oriental medicine would advance greatly if abdominal palpation were applied.

Clozapine is an atypical antipsychotic agent that is more effective than the typical neuroleptics in the treatment of refractory schizophrenia. Recently, there has been an increased recognition of the association of clozapine with myocarditis and cardiomyopathy. Commonly used diagnostic tests have limited sensitivity in diagnosing this potentially life-threatening complication. Here we report a case of 36-year-old male patient who developed fever, tachycardia, and dyspnea after introduction of clozapine. By clinical evaluation and laboratory test we diagnosed the patient with myocarditis and treated him successfully. To our knowledge this is the first case report of clozapine-induced myocarditis in Korea.

Angiogenesis, the formation of new capillaries from existing vessels, increases oxygenation and nutrient supply to ischemic tissue and allows tumor growth and metastasis. As such, angiogenesis targeting provides a novel approach for cancer treatment with easier drug delivery and less drug resistance. Therapeutic anti-angiogenesis has shown impressive effects in animal tumor models and are now entering clinical trials. However, the successful clinical introduction of this new therapeutic approach requires diagnostic tools that can reliably measure angiogenesis in a noninvasive and repetitive manner. Molecular imaging is emerging as an exciting new discipline that deals with imaging of disease on a cellular or genetic level. Angiogenesis imaging is an important area for molecular imaging research, and the use of radiotracers offers a particularly promising technique for its development. While current perfusion and metabolism radiotracers can provide useful information related to tissue vascularity, recent endeavors are focused on the development of novel radioprobes that specifically and directly target angiogenic vessels. Presently available proges include RGD sequence containing peptides that target ${\alpha}_v\;{\beta}_3$ integrin, endothelial growth factors such as VEGF or FGF, metalloptoteinase inhibitors, and specific antiangiogenic drugs. It is now clear that nuclear medicine techniques have a remarkable potential for angiogenesis imaging, and efforts are currently continuing to develop new radioprobes with superior imaging properties. With future identification of novel targets, design of better probes, and improvements in instrumentation, radiotracer angiogenesis imaging promises to play an increasingly important role in the diagnostic evaluation and treatment of cancer and other angiogenesis related diseases.

Introduction This study reports case series of Soyangin patients with coldness in hands and feet using Sasang constitutional medicine approach. This study suggests a value of using constitutional medicine indicators as both prognostic and diagnostic tools. Methods Among patients who visited an outpatient clinic, 7 patients were selected based on the criteria. These selected patients were exclusively treated with herbal medicine and monitored every 2 to 4 weeks retrospectively. Results The average treatment period was 8 weeks. Patients with a favorable pattern showed the improvement within 8 weeks, while those with an unfavorable pattern required more time. Discussion This study confirms the significance of Sasang constitutional medicine approach in Soyangin exterior cold syndrome with coldness in hands and feet. It also validates the current coldness in hands and feet as meaningful diagnostic indicator of Soyangin exterior cold syndrome. Furthermore, it highlights the value of original symptoms as prognostic tools.

Human Papillomavirus (HPV) infection is the most common sexually transmitted infection and is associated with the development of cervical cancer. The purpose of this report is to provide the literature evidences on selecting the HPV vaccine for national immunization program (NIP) in Korea. To complete these tasks, we reviewed domestic and foreign literature on the current status of HPV infection, efficacy and effectiveness of HPV vaccine, safety of vaccine and cost effectiveness analysis of vaccination business. Given that the median age of first sexual intercourse is continuing to fall, this may have serious implications for HPV infection and cervical cancer incidence at the age of 20s. The World Health Organization recommends that the HPV vaccination should be included in the NIP being implemented in each country. Both the bivalent and quadrivalent vaccines have a 90% or greater preventive efficacy on cervical intraepithelial lesion 2-3 and cervical cancer by the HPV 16 or HPV 18. In the future, if HPV vaccination rate as part of NIP increases, it is expected that the incidence of HPV infection, genital warts, and cervical precancerous lesions will be decreased in the vaccination age group. Therefore, in order to increase the HPV vaccination rate at this point in Korea, social consensus and efforts such as the introduction and promotion of HPV vaccine to the NIP according to appropriate cost-effectiveness analysis are required.

Coagulation involves the regulated sequence of proteolytic activation of a series of proteins to achieve appropriate and timely hemostasis in an injured vessel. In the non-pathological state, the inciting event involves exposure of circulating factor VIIa to extravascularly expressed tissue factor, which brings into motion the series of steps which results in cell based model of coagulation. In the new concepts of coagulation system, initiation, amplification and propagation steps are involved to converse of fibrinogen to fibrin. The precisely synchronized cascade of events is counter-balanced by a system of anticoagulant mechanisms. Developmental hemostasis refers to the age-related changes in the coagulation system that are most marked during neonate and childhood. An understanding of these changes in crucial to the accurate diagnosis of hemostatic abnormalities in neonate and children. This review aims to elucidate the main events within the coagulation cascade as it is currently understood to operate in vivo, and also a short review of the anticoagulants as they relate to this model. Also this paper describes the common pitfalls observed in the clinical data related to the coagulation system in neonate to children.

Introduction: The aim of this study is to report on the effectiveness of Korean medicine to improve symptoms of chemotherapy-induced peripheral neuropathy (CIPN). Some patients are treated with medication, but medications may have no effect in some patients. Korean medicine treatments have been used in such patients, but few reports exist. Case Presentation: A 58-year-old female patient with CIPN reported symptoms of bilateral limb pain and tingling sensations as well as cold sensations in bilateral lower legs and hands, fatigue, and bilateral limb weakness. To reduce the patient's symptoms, we provided Korean medical treatment, including herbal medicine (Uchashinki-hwan), acupuncture, and moxibation. To evaluate the results of this treatment, we used a numeric rating scale (NRS), the manual muscle test (MMT), the National Cancer Institute Common Toxicity Criteria for Adverse Events (CTCAE), and the European Organization for Research and Treatment of Cancer quality-of-life questionnaire about CIPN (EORTC-QLQ-CIPN20). After 49 days of treatment, the NRS scores decreased for bilateral limb pain and tingling, for bilateral lower leg and hand cold sensation, and for fatigue. The MMT results for the upper and lower extremities were improved. CTCAE Grade and EORTC QLQ-CIPN20 score were also decreased. Conclusion: According to these results, Korean medicine treatment may be considered an effective treatment for CIPN. Prospective studies are needed in the future to confirm and expand these findings.

In this study, we examine Cho Heon-yeong's medical theory in obstetrics and gynecology by looking at the contents and prescriptions of 『Buinbyeongchiryobeob (婦人病治療法)』. This book is a clinical text on obstetrics and gynecology written in the 1940's. This book consists of an Introduction, Jeungchi (證治), Yangjinhanchi (洋診漢治), Cheobangnonhae (處方論解) and refers to 『Donguibogam(東醫寶鑑)』, 『Keongakjeonseo (景岳全書)』, 『Junguihaksajeon (中醫學辭典)』, 『Jejungsinpyeon (濟衆新編)』, 『Uihakipmun (醫學入門)』 and 『UijongKeumkam (醫宗金鑑)』. Cho Heon-yeong's theory in this book has the following characteristics. First, his medical eclecticism is centered on Korean Medicine, with incidental use of Western medicine. Second, he regarded weakness (虛證) as a vital factor in obstetrics and gynecology. Third, he added "mental state" to the list of basic physiological characteristics of women. Fourth, he presented a new diagnostic standard based on a spectrum of fire (火) and cold (冷). There are 363 prescriptions in this book, and 171 of them are from 『Donguibogam (東醫寶鑑)』. The books frequently used prescriptions are all designed to supplement (補藥). There are 48 prescriptions that original to Cho Heon-yeong. Additionally, this book contains eopsaeng (攝生) and pretended stimulation therapies and exercise methods.

Traditional mediation analysis, which relies on linear regression models, has faced criticism due to its limited suitability for cases involving different types of variables and complex covariates, such as interactions. This can result in unclear definitions of direct and indirect effects. As an alternative, causal mediation analysis using the counterfactual framework has been introduced to provide clearer definitions of direct and indirect effects while allowing for more flexible modeling methods. However, the conceptual understanding of this approach based on the counterfactual framework remains challenging for applied researchers. To address this issue, the present article was written to highlight and illustrate the definitions of causal estimands, including controlled direct effect, natural direct effect, and natural indirect effect, based on the key concept of nested counterfactuals. Furthermore, we recommend using 2 R packages, 'medflex' and 'mediation', to perform causal mediation analysis and provide public health examples. The article also offers caveats and guidelines for accurate interpretation of the results.
