Epidemiological profile of methanol poisoning, el hajeb, Morocco

Abstract

Background: Methanol poisoning is of particular importance in low and middle-income countries. We reported on a methanol poisoning incident that occurred 22 May 2017, in El Hajeb (Morocco). Aims: This study aimed to describe the extent of the intoxication, determine its source and implement the necessary preventative measures. Methods: We conducted a cross-sectional survey. A standardized questionnaire including socio-economic data, clinical symptoms and time of use was administered face-to-face to cases of methanol poisoning. Biological samples were taken for toxicological analysis. Data were entered and analyzed on Epi Info version 7. Results: Twenty-six cases of methanol poisoning were surveyed with a mean age of 39.7 (SD 11.1) years and a male/female sex ratio of 5.5. All intoxicated cases were of low socioeconomic status. The mean latency period between use and symp-tom onset was 1.5 (SD 1) days. Reported symptoms were mildly altered consciousness in 14 cases (53.8%), abdominal pain in 10 cases (38.5%), headache in 9 cases (34.6%), vomiting in 8 cases (30.8%) and coma in 7 cases (27.1%). Mortality was 65% and 4 cases developed blindness. Laboratory results confirmed the presence of methanol in the blood with values greater than 0.6 g/L. The dose of methanol in the associated bottle was 217 g/L. Conclusion: Public awareness of the dangers of methanol intoxication is important. Health professionals need to be aware of the clinical signs and what to do in the event of methanol poisoning.
