Pleomorphic adenoma (PA) is a benign tumor which usually originates from major and minor salivary glands. This tumor arising outside submandibular gland (SMG) is extremely rare. To author's knowledge, only four cases have been reported so far in English literature. Its pathogenesis is still unclear, but it can be explained by embryologic theory of major salivary gland. A 68-year-old man with an incidental mass on left upper lateral neck visited to our clinic. The radiologic findings showed well-margined round mass outside left SMG. The excisional biopsy revealed a pleomorphic adenoma. We report the rare and unique case with a brief literature review.

Having an understanding of the properties of cytokines is essential for the immunologist, the researcher and the medical practitioner who need to understand immunologic diseases and immunological therapeutic approaches. Cytokines are redundant in their actions on target cells and promiscuous in their receptor reactions. (ED note: That is some cool use of English!) Moreover, many cells concomitantly produce several cytokines that have overlapping actions. Here this review provides conceptual framework to understand the intriguing aspects of the cytokine system.

Primary diffuse large B-cell lymphoma of the seminal vesicle is an extremely rare disorder, with only two cases reported in the English literature. Here, we present imaging findings of a case of primary diffuse large B-cell lymphoma of the seminal vesicle. On transrectal ultrasonography, the mass presented as a 3.0-cm-sized heterogeneous, hypoechoic lesion in the right seminal vesicle. Computed tomography (CT) revealed a mass with rim-like enhancement in the right seminal vesicle. On magnetic resonance imaging (MRI), the tumor showed iso-signal intensity on T1-weighted images and heterogeneously intermediate-high signal intensity on T2-weighted images. The tumor showed rim-like and progressive enhancement with non-enhancing portion on dynamic scanning. Diffusion restriction was observed in the mass. On fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) imaging, a high standardized uptake value (maxSUV, 23.5) by the tumor was noted exclusively in the right seminal vesicle.

Many studies have investigated the prevalence of neck pain (NP) and its risk factors in the general population. However, the prevalence of NP among athletes has not yet been systematically investigated. We aimed to systematically review the prevalence of NP in athletes. A comprehensive search was conducted in September 2015 using PubMed, Ovid SP Medline, ISI, and Google Scholar. We included studies in English that reported the prevalence of NP in an athletic population during a defined period of time. We assessed the risk of bias in studies due to various definitions of NP, response rates, and reliability of the study instruments. Two reviewers independently assessed the studies' quality and performed data extraction. Of 1,675 titles identified, eight articles were assessed for risk of bias, and six with low or moderate risk were included. NP was shown to be prevalent in athletes, with a 1-week prevalence ranging from 8% to 45%, a 1-year prevalence ranging from 38% to 73%, and a lifetime prevalence of about 48%. The prevalence of NP in athletes is high. More studies regarding the prevalence and risk factors of NP may be useful for planning educational programs and developing appropriate rehabilitation protocols and preventive guidelines. Researchers are encouraged to perform epidemiologic studies in athletes with a low risk of bias.

Objective: Clinical and Experimental Reproductive Medicine (CERM) converted its language to English only beginning with the first issue of 2011. From that point in time, one of the goals of the journal has been to become a truly international journal. This paper aims to identify the position of CERM in its scholarly journal network based on the journal's metrics. Methods: The journal's metrics, including citations, countries of author affiliation, and countries of citing authors, Hirsch index, and proportion of funded articles, were gathered from Web of Science and analyzed. Results: The two-year impact factor of 2013 was calculated at 0.971 excluding self-citation, which corresponds to a Journal Citation Reports ranking of 85.9% in the category of obstetrics and gynecology. In 2012, 2013, and 2014, the total citations were 17, 68, and 85, respectively. Authors from nine countries contributed to CERM. Researchers from 25 countries cited CERM in their articles. The Hirsch index was six. Out of 88 original articles, 35 studies received funds (39.8%). Conclusion: Based on the journal metrics, changing the journal language to English was found to be successful in promoting CERM to international journal status.

In the circumstances of overflowing numbers of medical journals, progress of their own medical journal is one of the primary concerns of many medical societies. Among the 46-year-history of Journal of Korean Neurosurgical Society (JKNS), it undertook a period of important transition and preparation to take off for journal with international reputation during the period from 2001 to 2006. The overall process of manuscript handling, peer review, and editorial work has undergone systematic improvement. Workshops for authors, reviewer and editors were held, which were very helpful to improve the quality of submitted manuscript, peer review and editorial processing. Articles on the history, current status of the JKNS, citations and the change of proportion of types of articles were published, which provided insight about present condition and direction for further progress. It was changed into English journal in 2005. These efforts resulted in registration of the journal Chemical Abstract Service in 2005 and Science Citation Index Expanded in 2008 and SCOPUS in 2009. Now JKNS has become international journal, with about half of the submitted manuscripts from abroad, with increasing impact factor. Along with the effort of Korean Neurosurgical Society (KNS) members and support of KNS, dedication of Professor Dong Gyu Kim for the progress of JKNS is worth remembering, who served as Editor-in-Chief of JKNS during this period.

Purpose: The aim was to verify if changing the Journal of Gastric Cancer (JGC) to only English (starting in December 2010) was successful based on bibliometrics. Materials and Methods: The following indicators were retrieved or calculated from the journal homepage and the Web of Science Core Collection on January 30, 2016: the number of citable articles per year; the number of original articles funded; the national origins of the editorial board members and authors; the total citations; the impact factors; the national origins of authors citing the journal; the source titles of articles citing the journal; and the Hirsch index. Results: From 2011 to 2015, the number of citable articles per year was 40, 41, 39, 39, and 40. The proportion of original articles funded was 39 out of 113 articles (34.5%). The editorial board members were from seven countries. The authors were from 11 countries. The total citations increased from 1 in 2011 to 245 in 2015. From 2013 to 2015, the impact factors (without self-citations) were 1.42, 1.36, and 1.60. In 2014, the value 1.60 corresponded to the ranking of 157 out of 210 oncology journals (74.8%); It was cited from 46 countries. Top-ranking countries of citing authors were China (171), Korea (158), and Japan (75). The number of source titles citing the journal was more than 100. The Hirsch index was 12. Conclusions: The English-only language policy, which started in December 2010, was successful in promoting the JGC to international levels from the perspective of bibliometric analysis.

Objective: This study conducted an empirical research on foreign patients who had visited the medical institutions of Daegu region in order to identify the effects of the factor satisfaction and experience satisfaction with medical services on their revisit intentions. Methods: This study reviewed the existing studies on medical services to foreign patients with a main focus on medical tourism, and conducted the empirical research through a survey on foreign patients from the Russian, Chinese and English-speaking regions based on the Daegu Medical Tourism Promotion Institute's DB of foreign patients. The empirical research conducted a multiple regression analysis on factor satisfaction and experience satisfaction regarding return visit intentions. Results: The multiple regression analysis results showed that both the factor satisfaction and the experience satisfaction with medical services of foreign patients had positive effects on their return visit intentions, especially, with a relatively greater effect from the factor satisfaction. Specifically, it was found that factor satisfaction elements of 'friendliness of employees', 'good communication', and 'expertise of medical workers'; and experience satisfaction elements of 'reliability of medical information', 'efforts to minimize incompatibility towards foreigners', 'convenient access to medical information' and the like enhanced the return visit intentions. Conclusion: We discovered that, in the context of medical tourism activities, it is important to enhance factor satisfaction and experience satisfaction with medical services in order to promote return visits of the foreign patients who we once attracted. Especially, there are implications that reliability of medical information and efforts to minimize incompatibility towards foreigners enhance return visits of foreign patients.

This paper describes a method of building Korean conversational speech data in the emergency medical domain and proposes an annotation method for the collected data in order to improve speech recognition performance. To suggest future research directions, baseline speech recognition experiments were conducted by using partial data that were collected and annotated. All voices were recorded at 16-bit resolution at 16 kHz sampling rate. A total of 166 conversations were collected, amounting to 8 hours and 35 minutes. Various information was manually transcribed such as orthography, pronunciation, dialect, noise, and medical information using Praat. Baseline speech recognition experiments were used to depict problems related to speech recognition in the emergency medical domain. The Korean conversational speech data presented in this paper are first-stage data in the emergency medical domain and are expected to be used as training data for developing conversational systems for emergency medical applications.

Background: To compare the effects of two adjuvant chemotherapy regimens, anthracycline-based and cyclophosphamide, methotrexate, fluorourical (CMF) on disease free survival for breast cancer patients in the Eastern Mediterranean region and Asia. Methods: In a systematic review with a multivariate mixed model meta-analysis, the reported survival proportion at multiple time points in different studies were combined. Our data sources were studies linking the two chemotherapy regimens on an adjuvant basis with disease free survival published in English and Persian in the Eastern Mediterranean region and Asia. All survival curves were generated with Graphdigitizer software. Results: 14 retrospective cohort studies were located from electronic databases. We analyzed data for 1,086 patients who received anthracycline-based treatment and 1,109 given CMF treatment. For determination of survival proportions and time we usesb the transformation Ln (-Ln(S)) and Ln (time) to make precise estimations and then fit the model. All analyses were carried out with STATA software. Conclusions: Our findings showed a significant efficacy of anthracycline-based adjuvant therapy regarding disease free survival of breast cancer. As a limitation in this meta-analysis we used studies with different types of anthracycline-based regimens.
