We assessed the accuracy of clinical evaluation, arthrography and arthroscopy in the diagnosis of meniscal lesions in ninty knees in which arthrotomy was performed for disabling symptoms after evaluation by these three methods. At surgery, ninty-two menisci were removed, of which seventy-two were abnormal and twenty were normal. In these ninty-two menisci, correct diagnostic rate was made clinically 78%, arthrographically 70% and arthroscopically 86%. Arthrographic diagnosis was least accurate for lesions of the lateral meniscus and arthroscopic diagnosis was least accurate for lesions of the posterior horn of the medial meniscus and peripheral lesions. Based on this study, it was concluded that both the arthrography and arthroscopy are valuable technique for diagnosis of meniscal lesions.

Background and Objectives:
Brugada syndrome (BrS) is an inherited arrhythmia syndrome that presents as sudden cardiac death (SCD) without structural heart disease. One of the mechanisms of SCD has been suggested to be related to the uneven dispersion of transient outward potassium current (Ito ) channels between the epicardium and endocardium, thus inducing ventricular tachyarrhythmia. Artemisinin is widely used as an antimalarial drug. Its antiarrhythmic effect, which includes suppression of Ito channels, has been previously reported. We investigated the effect of artemisinin on the suppression of electrocardiographic manifestations in a canine experimental model of BrS.
Methods:
Transmural pseudo-electrocardiograms and epicardial/endocardial transmembrane action potentials (APs) were recorded from coronary-perfused canine right ventricular wedge preparations (n=8). To mimic the BrS phenotypes, acetylcholine (3 μM), calcium channel blocker verapamil (1 μM), and Ito agonist NS5806 (6–10 μM) were used.Artemisinin (100–150 μM) was then perfused to ameliorate the ventricular tachyarrhythmia in the BrS models.
Results:
The provocation agents induced prominent J waves in all the models on the pseudoelectrocardiograms. The epicardial AP dome was attenuated. Ventricular tachyarrhythmia was induced in six out of 8 preparations. Artemisinin suppressed ventricular tachyarrhythmia in all 6 of these preparations and recovered the AP dome of the right ventricular epicardium in all preparations (n=8). J wave areas and epicardial notch indexes were also significantly decreased after artemisinin perfusion.
Conclusions
Our findings suggest that artemisinin has an antiarrhythmic effect on wedge preparation models of BrS. It might work by inhibition of potassium channels including Ito channels, subsequently suppressing ventricular tachycardia/ventricular fibrillation.

PURPOSE: Addressing a patient's chief complaint is the first and key element of treating patients. This study determined the effectiveness of emergency medical technician and residents of an emergency department in addressing a patient's chief complaints. If emergency and hospital personnel misunderstand the chief symptoms of patients it could result in erroneous transport and treatment, thus losing precious time in finding the proper treatment. METHODS: A retrospective chart review study was performed in 1137 patients (at least 18 years of age), who visited one university hospital, for a period of 3 months. Patients who were did not undergo trauma, addiction, and cardiac arrest were included. RESULTS: A total of 150 cases (13.2%) did not match the chief symptoms reported by 119 emergency medical personnel and emergency medicine residents. Systemic symptoms, nervous system symptoms, and psychiatric symptoms were the main categories inconsistently assessed. The rank and certification of emergency medical technicians did not make a difference, but older patients (59 years of age or older) were statistically different. The assessment fo chief symptoms by an emergency medical resident tended to be more accurate than assessment of emergency medical technicians in the final diagnosis. CONCLUSION: Systemic symptoms, nervous symptoms, and psychiatric symptoms, were chief complaines easily misreported for older patients. This likely reflects a difficulty in the evaluation of obscure symptoms in older patients. It will require specific additional training programs to improve the response to these chief complaints.

Background:
The World Health Organization (WHO) proposed a global action plan for dementia and aimed to have 75% of their member states formulating National Dementia Plans (NDPs) by 2025. The Organization for Economic Cooperation and Development (OECD) proposed the ten key objectives of dementia policy in 2015. Among previous studies on NDPs, few studies have investigated measures for proper implementation of NDPs. This study aimed to compare the implementation basis and specific action plans of NDPs between the G7 countries and South Korea.
Methods:
We investigated the measures for proper implementation of the NDPs of G7 countries and South Korea. To compare the specific policy approaches, the seven action areas of the WHO action plan and the ten key objectives of dementia policy proposed by the OECD were integrated into 11 targets (prevention, diagnosis, awareness, caregiver support, appropriate environments, long-term care, health service, end-of-life care, care coordination, research and technology, information systems).
Results:
Although most NDPs included specific action plans of the 11 targets, caregiver support, safe environments, healthcare services, and end-of-life care were lacking in some NDPs. For implementation, some countries reinforced the policy priority of their NDPs by timely updates, evaluation, legislations, or head-of-state leadership. However, only three countries had a legislative basis, and three countries included outcome measures in their latest NDP.
Conclusion
Effective measures for feasible implementation are needed. The WHO should promote not only the establishment of NDPs, but also their proper implementation.

Scrub typhus is a zoonosis transmitted by a chigger of trombiculid mite and manifested with fever, skin rash, myalgia, and hepatitis etc. The renal involvement of the disease is prese-ted with transient microscopic hematuria and/or proteinuria. However acute renal failure or meningoencephalitis is very rare. We report a case of scrub typhus manifested with acute renal failure, meningoencephalitis, and hepatitis. The patient was treated with doxycycline and continuous arteriovenous hemofiltration (CAVH) and recovered successfully.

Isthmiophora hortensis (Digenea: Echinostomatidae) is a dominant echinostome in animal reservoir hosts and humans in the Republic of Korea (Korea). We intended to investigate the infection status with this echinostome species in the several species of wild animals and describe the morphological characteristics in the faunistic view point. A total of 175 animal carcasses belonging to 3 families, i.e., Canidae, Felidae and Mustelidae, were collected from the southern regions of Korea from March 2010 to July 2017. Isthmiophora spp. worms were recovered from the small intestines of each animal under a stereomicroscope after washing of intestinal contents. Isthmiophora hortensis was recovered from 4 species of wild carnivores, i.e., Nyctereutes procyonoides (3/107: 2.8%), Mustela sibirica (11/31: 35.5%), Meles lucurus (2/3: 33.3%) and Martes flavigula (1/2: 50%). The other 3 carnivores comprising stray dogs, cat and leopard cat were negative for I. hortensis infection (0/2, 0/10 and 0/12, respectively). Specimens obtained from the Lutra lutra (6/8: 75%) were identified as a distinct species, I. inermis, by morphological comparison. Isthmiophora inermis has thinner body, elongate testes and different anterior limits of vitelline fields. Detailed morphological descriptions and comparisons with the morphological characteristics are provided. Conclusively, it was confirmed for the first time that 3 species of mustelid mammals, i.e., M. sibirica, M. lucurus, and M. flavigula, are to be the new definitive hosts of I. hortensis in Korea. Additionally, I. inermis is to be newly added in the Korean echinostome fauna.

PURPOSE: Today's clinical nurses deal with complex problems that need accurate evidence for practice and decision making. In this study the effectiveness of an EBP education program was examined. METHODS: A pre-posttest design was used for this study and participants were 46 nurses working at a tertiary hospital located in Suwon, Korea. Date collection was done before and after the education program, from July 27 to October 2, 2015. Data were analyzed using paired t-test and ANCOVA with SPSS 21.0. RESULTS: There were significant differences in scores before and after the EBP education program for EBP readiness: belief (t=-5.65, p<.001), implementation(t=-2.89, p=.006), competence (t=-4.21, p<.001), and for evidence-based decision making (t=-16.25, p<.001) by the nurses. CONCLUSION: The findings indicate that the EBP education program has positive effects on EBP belief, implementation, competence and evidence-based decision making. In the future, it is necessary to reinforce the content of the program in the clinical workplace and to provide continuous education for clinical nurses.
