Lee Jema said in his book, Dongui Susebowon, that the prescriptions for Soum constitutional type were already developed by doctors during the Song Jin Yuan China around 10th-13th century. Those prescriptions were common techniques that were used throughout the East Asian region. Among them, Lee Jema specially selected some candidate formulas and modified them according to his constitutional theory. This study investigated how similar his modified prescriptions to original formulas through database[ancient formula database] analysis. 24 out of 24 Soum prescriptions selected meaningful ingredient herbs from the original formula. A 50% or higher concordance rate compared to the original formulas. There are only 9 treatment prescriptions that cannot be checked in the ancient formula database. A future task will be to reveal the practical meanings of the ingredients Lee Jema adjusted for the Soum constitutional type patients.

Objectives The purpose of this study was to evaluate the possibility of Korea Sasang Constitutional Diagnostic Questionnaire(KS-15) when was applied to the Vietnamese. Methods The subjects of this study were Vietnamese participants who visited National Hospital of Traditional Medicine in Hanoi in 2012-2013 among the data established at the Korean Medicine Data Center. Among them, 188 people were used to assess the reliability, and 116 people were used to assess the validity. The reliability test was conducted through test-retest analysis, and the validity test was conducted through cross analysis comparing to diagnosis by Sasang Constitutional experts. Results & Conclusions Three items of total 14 items, except for BMI, showed 0.4 or below in Kappa, 3 items were ranged in 0.4-0.6 and 8 items showed 0.6 or over, using 188 people. The concordance rate between the results of KS-15 and diagnosis of experts was 66.4% in 116 people (85.4% in Taeeumin, 47.4% in Soeumin, and 64.9% in Soyangin). The KS-15 could be usable for supporting to diagnose the Sasang constitution of the Vietnamese.

Object : Traditional Korean Medicine Diagnostic Support System(TKMDSS) is the diagnostic prescribing system based on ontology developed by Korea Institute of Oriental Medicine. We monitored and assessed its usefulness and searched for improvements. Methods : We collected 10 cases of stroke inpatients of Dongguk University Ilsan Oriental Hospital. They were diagnosed by primary care physician and another researcher who monitored using "TKMDSS" respectively. We compared the process and results of two diagnosis. Results : The diagnostic concordance rate between primary care physician and researcher were pretty high. Most of the problems were caused by expressions on symptoms inappropriate use of terminology. The severity of symptoms and vague symptoms which is hard to be diagnosed should be reflected and measured in this system. Conclusions : The problems were about terminology and definition. The terminology should be defined accurately and in-depth detail so that anyone can get the right information. If the problems were modified, "TKMMSS" could be utilized as supportive measures for oriental medicine doctors and students.

The results of rapid antimicrobial susceptibility test (AST) in blood cultures were obtained by inoculating the bacteria directly into the VITEK MS and the VITEK 2 systems without subculturing in the blood culture positive medium. The obtained results were compared with the results using a standard method to evaluate their reliability and accuracy. The direct AST results in blood culture positive specimens were 97.9% (1,936/1,978), consistent with the standard AST results. Gram-positive bacteria showed a concordance rate of 97.2% (1,051/1,081), a very major error rate of 0.5% (5/1,081), a major error rate of 0.1% (1/1,081), and a minor error rate of 2.2% (24/1,081). Staphylococcus epidermidis was the main cause of discordance, and gentamicin (N=9) and fusidic acid (N=8) showed high errors. The overall concordance rate and minor error among the Gram-negative bacteria were 98.6% (885/897) and 1.4% (12/897), respectively. Escherichia coli and Pseudomonas aeruginosa were the major causative bacteria of Gram-negative bacteria. Among them, amoxicillin/clavulanic acid (N=3) showed high error. Direct AST met the CLSI criteria and shortened the reporting time by 24 hours; however, we found that there was a need to perform an addition test via disk diffusion for antimicrobials with very large errors. These results suggest that the method of direct AST in blood culture positive medium may be very useful in efficiently treating patients.

The widespread occurrence of drug-resistant Mycobacterium tuberculosis places importance on the detection of TB (tuberculosis) drug susceptibility. Conventional drug susceptibility testing (DST) is a lengthy process. We developed a rapid enzymatic color-reaction-based biochip assay. The process included asymmetric multiplex PCR/templex PCR, biochip hybridization, and an enzymatic color reaction, with specific software for data operating. Templex PCR (tem-PCR) was applied to avoid interference between different primers in conventional multiplex-PCR. We applied this assay to 276 clinical specimens (including 27 sputum, 4 alveolar lavage fluid, 2 pleural effusion, and 243 culture isolate specimens; 40 of the 276 were non-tuberculosis mycobacteria specimens and 236 were M. tuberculosis specimens). The testing process took 4.5 h. A sensitivity of 50 copies per PCR was achieved, while the sensitivity was 500 copies per PCR when tem-PCR was used. Allele sequences could be detected in mixed samples at a proportion of 10%. Detection results showed a concordance rate of 97.46% (230/236) in rifampicin resistance detection (sensitivity 95.40%, specificity 98.66%) and 96.19% (227/236) in isoniazid (sensitivity 93.59%, specificity 97.47%) detection with those of DST assay. Concordance rates of testing results for sputum, alveolar lavage fluid, and pleural effusion specimens were 100%. The assay provides a potential choice for TB diagnosis and treatment.

Most of the researches on fog in South Korea have been done based on the naked-eye observation but the number of observation sites is just 22. Considering the localities of fog and various durations, it is essential to utilize more than 250 visibility meters that measure visibility every minute. In this study, the visibility characteristics of visibility meters were compared with that of the naked-eye observation using one year data, 2016, and radiation fog and advection fog cases were analyzed in detail. The concordance rate of the two data set was 0.96~0.97, but discordance rate was 0.19~0.47. In general, visibility meters observed fog more frequently than naked-eye. The correlation between two data sets is clearly dependent on the visibility and geographic locations (fog/thick fog (< 100 m) of inland: 0.86/0.61; fog/thick fog: 0.65/0.73 of island/coastal site). In both fog cases, the fog events observed by naked-eye were consistently detected by visibility meters, and visibility meters clearly well detected very short fog/thick fogs. Formation and dissipation time of fog for the fog cases were similar but fog duration by visibility meters was shorter because of exclusion of temporary dissipated time. In addition, the visibility meters showed a detailed distribution of fog events that occurred simultaneously over South Korea. It would be useful to analyze the spatial and temporal characteristics of, in particular, thick fog using visibility meters. However, more works are needed for the filtering criteria for analyzing fog using visibility meters alone.

Background The prenatal ultrasound detection of cleft lip with or without cleft palate (CL/P) and its continuous management in the prenatal, perinatal, and postnatal periods using a multidisciplinary team approach can be beneficial for parents and their infants. In this report, we share our experiences with the prenatal detection of CL/P and the multidisciplinary management of this malformation in our institution's Congenital Disease Center. Methods The multidisciplinary team of the Congenital Disease Center for mothers of children with CL/P is composed of obstetricians, plastic and reconstructive surgeons, pediatricians, and psychiatrists. A total of 11 fetuses were diagnosed with CL/P from March 2009 to December 2013, and their mothers were referred to the Congenital Disease Center of our hospital. When CL/P is suspected in the prenatal ultrasound screening examination, the pregnant woman is referred to our center for further evaluation. Results The abortion rate was 28% (3/11). The concordance rate of the sonographic and final diagnoses was 100%. Ten women (91%) reported that they were satisfied with the multidisciplinary management in our center. Conclusions Although a child with a birth defect is unlikely to be received well, the women whose fetuses were diagnosed with CL/P on prenatal ultrasound screening and who underwent multidisciplinary team management were more likely to decide to continue their pregnancy.

In April 2009, the H1N1 pandemic influenza virus emerged as a novel influenza virus. The aim of this study was to compare the performances of several molecular assays, including conventional reverse transcription polymerase chain reaction (RT-PCR), two real-time reverse transcription (rRT)-PCRs, and two multiplex RTPCRs. A total of 381 clinical specimens were collected from patients (223 men and 158 women), and both the Seeplex RV7 assay and rRT-PCR were ordered on different specimens within one week after collection. The concordance rate for the two methods was 87% (332/381), and the discrepancy rate was 13% (49/381). The positive rates for the molecular assays studied included 93.1% for the multiplex Seeplex RV7 assay, 93.1% for conventional reverse transcription (cRT)-PCR, 89.7% for the multiplex Seeplex Flu ACE Subtyping assay, 82.8% for protocol B rRT-PCR, and 58.6% for protocol A rRT-PCR. Our results showed that the multiplex Seeplex assays and the cRT-PCR yielded higher detection rates than rRT-PCRs for detecting the influenza A (H1N1) virus. Although the multiplex Seeplex assays had the advantage of simultaneous detection of several viruses, they were time-consuming and troublesome. Our results show that, although rRT-PCR had the advantage, the detection rates of the molecular assays varied depending upon the source of the influenza A (H1N1)v virus. Our findings also suggest that rRT-PCR sometimes detected virus in extremely low abundance and thus required validation of analytical performance and clinical correlation.

Background: Activating mutations of epidermal growth factor receptor (EGFR) could predict response to tyrosine kinase inhibitor (TKI) treatment in patients with non-small cell lung cancer (NSCLC). However, the detection of EGFR mutation is frequently challenging in clinical practice for the lack of tumor tissue. The aim of this study was to investigate the feasibility of performing EGFR mutation testing on various types of liquid-based cytology (LBC) samples. Materials and Methods: A total of 434 liquid-based cytology samples were collected from March 2010 and November 2013. Among them, 101 with diagnosis of lung adenocarcinoma had paired surgically resected specimens. The ADx Amplification Refractory Mutation System (ADx-ARMS) was used to determine EGFR mutation status both in LBC and resected samples. Results: All liquid-based cytology samples were adequate for EGFR mutation analysis. The mutation rate was 50.5% in the 434 NSCLC patients with LBC samples and the incidence rates of EGFR mutation were consistent among different specimens. We also detected EGFR positives in 52.5% (53/101) patients with paired histologic specimens. The concordance rate of EGFR mutation between LBC samples and paired histologic specimens was 92.1%. Conclusions: Our results suggest that liquid-based cytology samples are highly reliable for EGFR mutation testing in patients with NSCLC.
