Based on the high rates of burn injuries in patients with epilepsy, it is crucial to evaluate the epidemiological factors, etiology, types of burns, and outcome of these certain individuals and to enhance knowledge about the possible risks of epilepsy-related burns by preventive actions and programs. Our retrospective study was carried out from September 2013 to February 2017 in Amir-al Momenin Hospital, a tertiary referral burns and plastic surgery healthcare center. Because of the fact that a number of patients with burns had experienced their trauma at the time of convulsion or in postconvulsion phase, it is necessary to evaluate the outcome, burn patterns, etiology of injury, and related epidemiological factors in order to develop a greater understanding of possible risks of epilepsy-related burns by preventive actions and programs. In our study, 2715 patients who referred to burn centers and hospitalized with a mean age of 26.838 (standard deviation (SD) = 21.186) were enrolled, in which 29 patients were involved in burn accidents due to epilepsy and seizure, resulting in a 1.1% epilepsy incidence in these individuals. In patients with seizure disorder, there was a mean rate of 5.8 (SD = 1.923) cases per year. Eighteen (62.1%) were male, and 11 (37.9%) were female. There were no cases of seizure-induced burn injury in pediatrics (< 15 years) in our study. Among the patients with seizure-induced burns, 11 (out of 1101; 37.9%) were from rural areas, while 18 (out of 1570; 62.1%) were from urban locations. The occurrence of accidents due to seizure was also categorized based on the season, with the highest occurrence during winter (12 out of 683; 41.4%) and lowest during spring (3 out of 659; 10.3%). The mechanism of burn in patients with seizures was also documented, in which 12 (41.4%) were due to liquid, 12 (41.4%) due to fire, 1 (3.4%) due to explosion, and 1 (3.4%) due to other objects. Out of patients with seizure-induced burns, 21 (72.4%) were discharged, 2 released with their own will, 1 was transferred, and 5 (17.2%) died in the course of hospitalization. This study demonstrates that burn injuries by epilepsy are a public health concern in low- and middle-income countries. Therefore, we suggest the execution of a strong national epilepsy preventive actions and programs, as well as proper education for both medical practitioners and patients of the possible dangers as part of an injury control program. • 1.1% of burn incidents were due to epilepsy and seizure. • Among the epilepsy-induced burn injuries, a mortality of 17.2% was observed. • Children are at a lower risk of developing epilepsy-induced burn injuries. • Preventive programs are required to reduce burn injuries in patients with epilepsy.

Groundwater aquifers are considered the second most abundant water supply for drinking water all over the world. In Iran, ground waters are commonly employed for drinking water, irrigation, and industrial purposes. Heavy metals (HMs) pose human concerns about the groundwater contamination; these pollutants are recognized to be capable of bio-accumulation, long persistence in the natural environment, and toxic effects. In the present research, the content of HMs: Chromium (Cr), Cadmium (Cd), and Lead (Pb) were detected in 89 water samples collected in 2018 by underground water supplies (active wells) of Saravan city. Hazard Quotient (HQ) and Monte Carlo Simulation approach with 10,000 repetitions were applied to discover the human non-carcinogenic impacts of HMs in four groups of ages (adults, teenagers, children, and infants) of consumers. The concentrations of Cr, Pb, and Cd were in the range of 0.49–20, 0.1 to 58.34, and 0.11–12.8 μg/L, respectively. The mean HQ calculated due to exposure to Pb (0.0018–0.0023), Cr (0.0112–0.0186), and Cd (0.0370–0.0615) were lower than one. The findings of sensitivity analysis revealed that HMs concentration had the most contribution effect on human non-carcinogenic risk analysis in four different exposed populations. This study could assist researchers to perform more comprehensive studies with more samples. Therefore, further research is required for decision-makers to plan proper measurements properly. • HRA procedure was conducted to evaluate the health effects of different population exposed to three HMs. • Pb HQ for population groups were in the order of infant > children > teenager > adult. • The most influential parameters in the risk of non-carcinogenicity were in the order ofconcentration > ingestion rate > body weight.

This paper considers exposure to the concentration of fluoride in drinking water resources of Showt city in West Azerbaijan Province in, Iran, and its related potential health risk assessment issues to the resident populations. For this purpose, 88 drinking water samples were analyzed in 2016 by using the spectrophotometric method. Non-carcinogenic health risks due to F exposure through consumption of drinking water were assessed using the US EPA method. In addition, the associated zoning maps of the obtained results were presented using a geographic information system (GIS). The results indicated that fluoride concentration in drinking water ranged from 0.0 to 5.5 mg L−1 of the study area. Based on this research, 36.36% of the samples had a fluoride level higher than the permissible level, 13.63% had less than the permissible limit, and 50% of the samples had a level within the optimum limit of 0.5–1.5 mg L−1. The Hazard Quotient index (HQ) for children, teenager and adults had health hazards (HQ > 1) in 54.55%, 31.82%, and 22.73% of samples, respectively. Groundwater resources having a risk of more than one were located in the villages of Khilajajam, Kolos, and Shorboulagh. So, in these study areas, there are potential risks of dental and skeletal fluorosis. • Fluorosis is a considerable health problem worldwide. • High concentrations fluoride above 3 mg l−1 may cause dental and skeletal fluorosis. • HQ indicated health risk assessment in relation to F- concentration for children and adults were significant. • The fluoride contamination must be reduced in this study area to decrease endemic fluorosis.
