From the more predictable response to seasonal influenza, which occurs each year, we have learned the importance of effective universal vaccines and therapeutic agents to protect high-risk groups. Heterologous vaccination with different types of vaccines to prevent COVID-19 is already recommended for various reasons: shortages of mass vaccine supply; critical adverse events, and potential superior efficacy as a booster dose. However, very few studies have examined the efficacy and safety of heterologous vaccination with mixed types. This review discusses the efficacy of vaccines currently approved in the Republic of Korea, including heterologous vaccination options.","PeriodicalId":84452,"journal":{"name":"Chungang uihak = The Korean central journal of medicine","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85788027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular mutations have been reported to contribute to the pathogenesis and prognosis of AML. Next-generation sequencing (NGS) has revolutionized the speed and cost of genomic sequencing and enables the parallel analysis of many genes for molecular risk stratification. The molecular mutations currently included in risk stratification at AML diagnosis are c-kit, FLT3-ITD, NPM1, CEBPA (biallelic), RUNX1, ASLX1, and TP53. The importance of screening for mutations has been further emphasized by introducing novel therapeutic targets for molecular mutations, such as FLT3-TKD, IDH1, and IDH2. Molecular mutations are also used to evaluate measurable residual disease during treatment and to select the intensity of the treatment during consolidation and follow-up. Pretreatment leukemic marrow and blood should be stored at a biobank to perform NGS analysis in cases of AML at diagnosis. Samples from various time points during and after treatment should be obtained and stored under appropriate conditions.","PeriodicalId":84452,"journal":{"name":"Chungang uihak = The Korean central journal of medicine","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81619675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prokinetics have conventionally been used to stimulate gastrointestinal propulsion and to treat symptoms correlated with motility problems, including gastroparesis and constipation. 5-Hydroxytryptamine receptor 4 (5-HT4) agonists, such as cisapride, very effectively increased human gastrointestinal tract motility. However, cisapride sometimes induced serious tachyarrhythmia; the drug was thus withdrawn from the market. Thereafter, many prokinetics have been developed to treat delayed gastrointestinal motility. However, some exhibit serious side-effects. Recently, a new, highly selective serotonin receptor agonist, prucalopride, has been introduced; there is as yet no evidence of serious cardiac side- effects. The drug has been approved by the Food and Drug Administration to treat chronic constipation. Thus, recently introduced, highly selective agents appear to show promise as treatments for gastrointestinal dysmotility; there seem to be no serious side-effects.","PeriodicalId":84452,"journal":{"name":"Chungang uihak = The Korean central journal of medicine","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87912399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adverse drug reactions (ADRs) to anti-tubercular drugs are common, and have a major impact on treatment maintenance and prognosis. It is important to understand the characteristics of ADRs and establish a suitable management plan. Methods: We retrospectively reviewed patients with ADRs during treatment with first-line antitubercular drugs such as isoniazid, rifampicin, ethambutol, and pyrazinamide from 2009 to 2018. Age, sex, and total treatment period, and the onset, severity, seriousness, and system organ class of ADRs, were analyzed to understand the characteristics of first-line anti-tubercular drug-related ADRs. Results: A total of 1,606 of 5,482 patients (29.3%) experienced ADRs after administration of first-line anti-tubercular drugs. The incidence of ADRs related to isoniazid, rifampicin, ethambutol, and pyrazinamide was 22.2%, 21.3%, 24.5%, and 29.6%, respectively. A total of 2,098 ADR reports were made (mean of 1.3 ± 0.6 per patient). The rates of mild, moderate, and severe ADRs were 32.4%, 61.1%, and 6.5%, respectively. There were 127 reports (6.1%) of serious ADRs. Skin and appendage disorders were most frequently reported (27.5%), followed by gastrointestinal disorders (17.5%), and liver and biliary system disorders (13.1%). The total treatment period was longer in patients who experienced ADRs (224.0 ± 3.1 days vs. 247.0 ± 4.7 days, p = 0.009). Conclusions: The incidence of ADRs to first-line anti-tuberculosis drugs was 29.3%, and 6.5% were severe ADRS. ADRs prolonged the overall treatment duration, indicating the importance of their detection and management.","PeriodicalId":84452,"journal":{"name":"Chungang uihak = The Korean central journal of medicine","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87606229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incidence of multiple myeloma (MM) in South Korea is rapidly increasing, and it is important to be aware of its initial clinical presentations and the most efficient laboratory algorithms for early detection. Serum protein electrophoresis (SPE) and urine protein electrophoresis (UPE) are the primary screening tests for patients with clinically suspected MM or amyloid light-chain amyloidosis; these tests are reimbursed in South Korea. We reviewed clinical studies that applied national and international guidelines to evaluate test panels for early detection of MGs, including MM. The serum free light chain (sFLC) with SPE panel is recommended for the initial work up for diagnosis of MGs. In the case of a normal SPE, sFLC should be measured subsequently, so as not to miss the presence of M-protein. Use of this screening panel avoids medical expenses related to delayed diagnosis. Guidelines and recommendations suggest that no single method (SPE, serum immunofixation electrophoresis, sFLC, or UPE) should be used to exclude a diagnosis of MM. We believe that a screening test panel comprising SPE plus sFLC will increase the rate of early and accurate diagnosis of MM and related disorders.","PeriodicalId":84452,"journal":{"name":"Chungang uihak = The Korean central journal of medicine","volume":"318 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79703717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, the current diagnosis and treatment policies for AF do not reflect its progression and complexity. In addition, the various factors related to AF diagnosis and treatment are not simple due to the diversification of tools, advances in treatment methods, and complex mechanism of AF. Therefore, there are many challenges to developing a simple AF classification system. To overcome these, there have been a number of attempts to systematically characterize AF according to treatment and prognosis rather than using a uniform classification. Further, as mentioned in the previous AF guidelines, further research is being conducted on an integrated patient–physician approach to AF. Such an approach would be the basis for consistent treatment based on the guidelines, and would help to improve patient outcomes. Further, for the integrated management of AF patients, some changes should be made to the current approach to develop a multidisciplinary approach, including changes to the behavior of team members, patients, their family members, and physicians. The Korean Heart Rhythm will introduce an integrated approach to the classification and structure of AF management, and provide guidelines for its application in clinical practice.","PeriodicalId":84452,"journal":{"name":"Chungang uihak = The Korean central journal of medicine","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89666953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it should be a priority to quickly detect tuberculosis mycobacterium and quickly exclude drug-resistant tuberculosis before treatment begins. To this end, recent guidelines recommend the general use of Mycobacterium tuberculosis (MTB) polymerase chain reaction (PCR) tests, Xpert MTB/RIF tests, and rapid sensitivity tests through line probe assay (LPA). In addition, if the results of the test are positive, it is important to establish an in-hospital reporting system so that rapid reporting can be made. The treatment principle for drug susceptible pulmonary tuberculosis is 2 months of initial intensive phase (isoniazid, rifampin, ethambutol, pyrazinamide) followed by 4 months of maintenance phase (isoniazid, rifampin). Despite global efforts to shorten the duration of the treatment, the treatment of drug susceptible pulmonary tuberculosis has not changed for more than 35 years, and problems such as increased side effects and reduced drug adherence are serious obstacles to tuberculosis management. Therefore, efforts have been steadily made to shorten the treatment period through the combination of new drugs worldwide, and after many failures, they are finally paying off. A recently published Study 31/A5349 study found that 4 months short-term regimen using rifapentine (RPT) and moxifloxacin (MFX) demonstrated non-inferiority in existing standard regimen, as the result, a revision of World Health Organization guidelines is scheduled that 4 months short-term regimen using RPT and MFX may be an alternative. However, it is unlikely that RPT/MFX 4 months short-term regimen will be applied immediately in Korea because the use of RPT is currently limited in Korea due to the high frequency of side effects.","PeriodicalId":84452,"journal":{"name":"Chungang uihak = The Korean central journal of medicine","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75267624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
