Workplace Accidents and Work-related Illnesses of Household Waste Collectors

BACKGROUND: Household waste collectors (HWCs) are exposed to hazardous conditions. This study investigates the patterns of workplace injuries and work-related illnesses of HWCs. METHODS: This study uses cases of workplace injuries and work-related illnesses of HWCs that occurred between 2010 and 2011. We analyzed 325 cases of injuries and 36 cases of illnesses according to the workers' age, length of employment, size of workplace, injured part of body, day and month of injury, type of accident, agency of accident, and collection process. RESULTS: There were significant differences in the effect of workers' length of employment, injured part of body, type of accident, agency of accident, and collection process. Results show that most injuries occur in workers in their 50s and older. This study also shows that 51.4% of injuries occur at businesses with 49 employees or fewer. Injuries to waste collectors happen most often when workers are electrocuted after slipping on the ground. The second most prevalent form of injury is falling, which usually happens when workers hang from the rear of the truck during transportation or otherwise slip and fall from the truck. Work-related illnesses amongst waste collectors are mostly musculoskeletal conditions due to damaging postures. CONCLUSION: These findings will be instructive in devising policies and guidelines for preventing workplace injuries and work-related illnesses of HWCs.

Comparisons of Traffic Collisions between Expressways and Rural Roads in Truck Drivers

BACKGROUND: Truck driving is known as one of the occupations with the highest accident rate. This study investigates the characteristics of traffic collisions according to road types (expressway and rural road). METHODS: Classifying 267 accidents into expressway and rural road, we analyzed them based on driver characteristics (age, working experience, size of employment), time characteristics (day of accident, time, weather), and accident characteristics (accident causes, accident locations, accident types, driving conditions). RESULTS: When we compared the accidents by road conditions, no differences were found between the driver characteristics. However, from the accident characteristics, the injured person distributions were different by the road conditions. In particular, driving while drowsy is shown to be highly related with the accident characteristics. CONCLUSION: This study can be used as a guideline and a base line to develop a plan of action to prevent traffic accidents. It can also help to prepare formal regulations about a truck driver's vehicle maintenance and driving attitude for a precaution on road accidents.

Lateralizing value of interictal epileptiform discharge in temporal lobe epilepsy

OBJECTIVE & BACKGROUND: There have been reports on the lateralizing value of temporal lobe interictal epileptiform discharge(IED), yet it is a matter of debate till now. We studied our patients focusing on the degree of lateralization by which accurate lateralization was possible and also on the significance of bisynchronous IED(BIED) in the lateralization of temporal lobe epilepsy. METHOD: Fifty two patients were included in the study who were diagnosed as having medial temporal lobe epilepsy through video-EEG monitoring and brain MRI. Twenty four hour sleep-deprived interictal scalp EEG was checked for all of them. After that, we counted the number of independent IED(IIED) and BIED originating from anterior temporal areas. Then we tried to find a reasonable degree of IED above which correct lateralization of epileptogenic area was possible by using brain MRI as a standard. We also tried to find a significance of BIED in the lateralization of temporal lobe epilepsy by comparing the result excluding patients with BIED to that includig patients with BIED. RESULT: Lateralization of IED was over 80% accurate if the cutoff point was set at 70% and patients with BIED were included, but nearly 100% accurate of the cutoff point was set at 80% and patients with BIED were excluded. CONCLUSION: Influence of BIED on the accuracy of lateralization by IED is significant, and if the lateralization of IED is over 80% in patients with no BIED, the chance of true lateralization is very high.
