RESUMO
Background: Pesticides are widely used to increase crop yields and vector control. However, both acute and chronic exposure have health consequences. There is paucity of information about the global occurrence of pesticide poisonings. Aim: To characterize the reports of pesticide exposures received by a University Poison Information Center. Material and Methods: All pesticide exposures reported in Chile between 2006 and 2013 were analyzed. A data-collection sheet provided by the International Programme on Chemical Safety of the World Health Organization, was used to collect information. Results: In the study period, 13,181 reports were analyzed. The main age groups exposed were preschoolers and adults. Sixty one percent of exposures occurred accidentally and 24.8% were suicide attempts. Exposures to acetylcholinesterase inhibitors was reported in 29.3% of cases, to superwarfarin rodenticides in 28.5% and to pyrethroids in 24.0%. An increased risk of suicide attempts with pesticides was observed among women, when compared with men (odds ratio: 1.5; 95% confidence intervals: 1.4-1.6; p < 0.001). The risk was higher among teenage girls. Conclusions: The amount of cases under acetyl cholinesterase inhibitor exposure, the most toxic pesticides currently in use should be highlighted. Workers should be educated and all cases should be reported to take actions aiming at reducing these events.

Background: Exposure to Biological Agents during work is an emergent type of occupational risk. Aim: To characterize occupational biological risk exposure among Chilean workers which have been registered by the Toxicology Information Center, between January 2006 and December 2009. Material and Methods: All incoming calls reporting exposure to biological agents during the studied period were analyzed. The information obtained from the caller was registered using the Communication Record Instrument of the WHO International Programme on Chemical Safety (IPCS INTOX). Results: In the studied period, 77 calls were received. The mean age of exposed patients was 35 ± 15 years and 57% of them were females. The most common involved agents were vaccines for veterinary use (42%) followed by Loxosceles laeta bites in 16%. The main routes of exposure were injections, cuts and needle stick injuries in 39% and stings and bites in 38%. The highest exposure rates were observed in Southern Chile due to self-inoculation of veterinary vaccines used in the salmon industry (22.7/100.000 actual workers). Fifty-eight percent of calls were from health care workers, and 51% of them were from health care facilities. Sixty percent of exposures occurred during summer and spring. There was a fourfold higher risk of calls involving women exposed to bites or stings (odds ratio (OR) 4.5 (CI95 1.5-13.9, p < 0.01). Men had a fourfold higher risk of being exposed to vaccines or medications for veterinary use (OR 4.2, CI95 1.4-12.6 p < 0.01). Conclusions: Most calls involving an exposure to a biological agent were caused by self-inoculation of veterinary medications.

In the last decades there has been an important decrease in infant mobidity and mortality, but these achievements are not equally distributed across thewhole population. Children are one of the most susceptible groups due to their unique vulnerabilities to environmental factors. Unhealthy environments, indoor pollution, poor drainage, inadequate waste disposal, and many others, are significant environmental risk factors to children. Currently, Chile is experiencing an advanced demographical transition, asituation that requires a precise approach to guarantee that the population has an adequate health status. It is important to take care of children, since their present health status will condition their health as adults. Pediatric Environmental Health Specialty Units are structures specialized in pediatric conditions related to the environment, formed by aninterdisciplinary and highly specialized team. These centers provide assistance, information and treatment, promote research, educate health care providers or the public, and report problems to authorities. Health authorities should emphasize the importance of having a safe environment for children and encourage efforts to reduce exposure to environmental hazards promoting healthy behaviors, education and awareness at all levels of society.

Background: Loxoscelism is caused by the bite of spider Loxosceles laeta. It can cause a cutaneous or systemic syndrome. Aim: To determine the epidemiol¢gica! and clinical features of patients bitten by the Chilean recluse spider (Loxosceles laeta). Material and Methods: All communications received at a telephonic orientation center for intoxications during 2005 were analyzed, selecting those who involved patients with symptoms that suggested loxoscelism (i.e., pain, burning sensation, blue area, hematuria, fever or myalgia). These were derived to the emergency room for confirmation of the diagnosis. Forty-eight hours after the initial communication, patients were contacted by phone to find out about the definitive diagnosis. The variables analyzed were: gender, age, geographical location, time since exposure, part of the body involved, clinical signs and definitive diagnosis. Results: Of 2,831 telephonic consultations with suspected loxoscelism, the diagnosis was confirmed in 287. All of these patients had cutaneous loxoscelism and only 7.3 percent of them developed visceral loxoscelism. Fifty six percent of patients with loxoscelism presented two or more clinical signs. The most common were a blue area, pain and a burning sensation, in 69 percent, 58 percent and 38 percent of patients, respectively. Fifty-one percent of patients developed signs within the first 12 hours. All patients with visceral syndrome presented with hemoglobinuria. No cases of loxoscelism were registered in areas located southern than the Xth region of Chile. There were no fatalities attributed to loxoscelism. Conclusions: Most cases of loxoscelism of this series were cutaneous. The population must be educated about the clinical signs of spider bite to seek early and adequate medical treatment.
