Dementia pugilistica (DP) or chronic traumatic encephalopathy (CTE) is a neurodegenerative disease or dementia that may affect amateur or professional boxers as well as athletes in other sports who suffer concussions. The condition is thought to affect around 15% to 20% of professional boxers and caused by repeated concussive or subconcussive blows. CTE was in the past referred to as dementia pugilistica, which reflected the prevailing notion that this condition was restricted to boxers. Recent research, however, has demonstrated neuropathological evidence of CTE in retired American football players, a professional wrestler, a professional hockey player and a soccer player, as well as in nonathletes. It is probable that many individuals are susceptible to CTE, including those who experience falls, motor vehicle accidents, assaults, epileptic seizures, or military combat, and that repeated mild closed head trauma of diverse origin is capable of instigating the neurodegenerative cascade leading to CTE. We report a 62-year old man suspicious of dementia pugilistica with clinical features of frontotemporal dementia and parkinsonism.

This article describes a systematic roadmap master plan for advanced industrial safety and health policy in Korea, with an emphasis on. Since Korean industries had first emergence of industrial safety and health policy in 1953, enormous efforts have been made on upgrading the relevant laws in order to reflect real situation of industrial work environment in accordance with rapid changes of Korean and global business over three decades. Nevertheless, current policy has major defects; too much techniques-based articles, diverged contents in less organization, combined enforcement and punishments and finally enforcing regulations full of commands and control. These deficiencies have make it difficult to accommodate changes of social, industrial and employment environment in customized fashion. The approach to the solution must be generic at the level of paradigm-shift rather than local modifications and enhancement. The basic idea is to establish a new system integrated with a risk assessment scheme, which encourages employers to apply to their work environment under comprehensive responsibility. The risk assessment scheme is designed to enable to inspect employers' compliances afterwards. A project comprises four yearly phases based on applying zones; initially designating and operating a specified risk zone, gradually expanding the special zones during a period of 3 years (2010-2012) and the final zone expanded to entire nation. In each phase, the intermediate version of the system is updated through a process of precise and unbiased validation in terms of its operability, feasibility and sustainability with building relevant infrastructures as needed.

PURPOSE: This study was conducted to analyze the factors associated with intoxicated patient's disposition in the pediatric emergency department. METHODS: We retrospectively evaluated pediatric intoxicated patients visiting the pediatric emergency department of a hospital between January 1, 2011 and December 31, 2013. Specifically, we analyzed the association between hospitalization recommended rate and the following variables: patient age group, symptoms, intentional poisoning, decontamination and toxic level of substance. RESULTS: We collected data from 345 patients. A high incidence was noted in the 1-4 years of age group and 10-15 years of age group. Unintentional poisoning occurred in 306 patients (88.7%). A total of 115 patients (33.3%) had symptoms when visiting. Forty three patients (12.5%) ingested cleaning substances, which was the most common agent. Potentially-toxic level was the most common level of the substance. The hospitalization recommended rate associated with visits in 2011 was 2.5 times greater than in 2012 and 2013, decontamination was 2.0 times greater than no decontamination, and poisoning with potentially-toxic substances was 2.6 times greater than poisoning with other toxic substances. Additionally, the hospitalization recommended rate associated with symptomatic patients was 2.4 times greater than that of asymptomatic patients and intentional poisoning was 2.4 times greater than unintentional poisoning. CONCLUSION: Patients with decontamination, ingestion of potentially-toxic substances, symptoms and intentional poisoning had increased hospitalization rates. In addition, the hospitalization rate for patients who visited in 2011 was greater than that of patients who visited in 2012 or 2013.

Creutzfeldt-Jakob disease (CJD) is a degenerative neurological disorder that is incurable and invariably fatal. It is characterized by rapidly progressive dementia presenting with memory loss, personality changes and hallucinations. The symptoms of CJD are caused by progressive death of neurons in the central nervous system, which is associated with build-up of the abnormal prion proteins forming amyloids. In human, CJD can be acquired genetically through a mutation of the gene encoding for the prion protein (PRNP). This occurs in only 5-10% of all CJD cases. We report a 64-year old woman with CJD carrying a V180I mutation that features late onset, rapid progression, no periodic sharp wave complexes on electroencephalography, and cortical signal change and edema in bilateral frontotemporoparietal lobes and basal ganglia on MRI.

BACKGROUND: Several studies have shown that the presence of cerebrovascular lesions may play an important role for determining the severity of the clinical symptoms of dementia. But no study to date has explored the clinical effect of cerebrovascular disease in Parkinson's disease with dementia (PDD), although cerebrovascular disease is common causes of dementia in elderly population. Therefore we conducted this study to evaluate the relationship between silent cerebrovascular lesions and cognitive decline in PDD. METHODS: Only 27 patients with PDD were chosen; 17 patients had PDD with silent cerebral ischemic lesions (PDDI) and 10 patients had PDD without silent cerebral ischemic lesions (pure PDD). These subjects received the global cognitive function testing and were all evaluated with detailed neuropsychological tests including attention, memory, language, and also the visuospatial and frontal function. RESULTS: There were no significant differences between pure PDD and PDDI group on general cognitive functions tests. Regard to mean time duration of suffering from Parkinson motor symptoms and motor function scale, pure PDD group showed more long duration than PDDI group but there was no significant difference between two groups. Furthermore, there were not any significant differences between the two groups on detailed neuropsychological tests. CONCLUSIONS: We concluded that silent cerebrovascular lesions do not contribute to neuropsychological severity of PDD, although vascular disease is a common cause of cognitive impairment in the elderly. Thus the results of the present study suggest that factors other than cerebrovascular disease contribute to severity of PDD.
