OBJECTIVES: Research on workplace violence has been conducted, but rarely has been organized systematically. In this study, we summarize the definition and classification of workplace violence studies and review the literature on workplace violence. METHODS: Using academic search engines PubMed, Google Scholar and DBpia, we found 856 papers including “workplace violence” and “adverse social behavior” AND workplace in the title published until December 2018, and 208 papers were selected. The selected papers were classified by continent and country, year of publication, occupation, classification criteria of workplace violence, and research topic. RESULTS: By country, the number of articles in the United States was the most with 40 (19.2%), followed by China 27 (13%), Korea 16 (7.7%), and Taiwan and Australia 15 (7.2%). By job category, healthcare workers accounted for the largest portion with 162 (79.0%) of the total, and 80 of them were conducted on nurses. Other occupations included civil servants, manufacturing workers, toll collectors and wageworkers. Among the classification methods of workplace violence, 147 (67.4%) articles were classified as type and there was a difference in the type of violence defined for each article. In the research topic, 114 (44.2%) articles analyzed the effects of workplace violence, and 105 (40.7%) articles describe the prevalence and characteristics of workplace violence, and 23 (8.9%) articles analyzing the causes of violence. CONCLUSION: The research topic is biased toward the field of healthcare, so it is necessary to expand to include various occupations or other specified occupations. It is also necessary to prepare appropriate measures against workplace violence.

A 30-year-old man was admitted to our hospital because of fatigue, palpitation and severe weakness of both legs. The admission laboratory findings revealed thyrotoxicosis, and 131I thyroid scintigraphic imaging revealed a low radioactive iodine uptake. He was treated for painless thyroiditis for about 4 months. However, thyrotoxic state had continued and radioactive iodine uptake was markedly increased in the follow up scan. Painless thyroiditis often relapses, but rarely develops into Graves' disease. This is a rare case in which painless thyroiditis was followed by Graves' disease.

BACKGROUND: Small proportions of all the elderly stroke patients receive recombinant tissue plasminogen activator (r-tPA) therapy, although old age is not a proven contraindication to intravenous thrombolytic therapy for acute ischemic stroke. The purpose of this study was to identify reasons for exclusion from r-tPA therapy and factors associated with the decision of r-tPA use in elderly patients with acute ischemic stroke. METHODS: From the acute stroke registries of 22 domestic university hospitals taking the r-tPA therapy from January 2007 to May 2010, we extracted data of all acute ischemic stroke patients who were aged 80 or over and arrived within onset 3 hours. For all patients, we assessed the eligibility of r-tPA therapy using National Institute of Neurological Disorders and Stroke (NINDS) r-tPA trial criteria. For eligible patients, we compared all clinical variables between patients who were treated with r-tPA and those who were not, and analyzed potential factors related to the decision of r-tPA use. RESULTS: A total of 494 patients were included in this study. 255 patients (51.6%) were excluded by NINDS r-tPA trial criteria and the major reasons for exclusion were minor neurological deficit (53.7%) and clinical improvement (17.3%). Among 239 patients who were eligible for r-tPA, 162 (32.8%) patients received r-tPA and 77 (15.6%) did not. Multivariable analysis showed that younger age, shorter time-delay from onset to admission, non-smoker, no history of prior stroke, good pre-stroke functional status and severe initial neurological deficit were independently associated with the decision of r-tPA use in the elderly stroke patients predictors for r-tPA treatment. CONCLUSION: In very elderly patients, mild neurological deficit on arrival and rapid clinical improvement in neurological symptoms were the main reasons for exclusion from thrombolytic therapy.
