PEDROZO, María Esther et al. Cases of acute pesticide poisoning in Colonia Puerto Pirapó, Itapúa, Paraguay, February, 2014. Biomédica [online]. 2017, vol.37, n.2, pp.158-163. ISSN 0120-4157.  https://doi.org/10.7705/biomedica.v37i3.3264.

In Paraguay, pesticides are the causative agent in 13.7% of poisonings, especially organophosphorus compounds. Such poisoning produces the inhibition of acetylcholinesterase generating three possible clinical conditions: acute poisoning, intermediate syndrome or late neurotoxicity.

We present 15 cases of acute poisoning, ten women and five men from a rural community between 5 and 67 years of age, whose symptoms began after using water contaminated by pesticides from the community network. The most common symptoms were nausea and vomiting, followed by abdominal pain, headache, fever, itching, red eyes and sweating. Five patients underwent blood tests for blood count, renal and liver function and serum cholinesterase, with results within the reference values; just one patient had high liver enzymes.

In two samples from the community water supply network the active compound detected was profenophos. It is essential to train primary health care personnel to identify cases of acute pesticide poisoning in a timely manner to provide appropriate treatment, especially in rural areas. Additionally, it is necessary that responsible institutions monitor compliance with environmental regulations in these areas to avoid such incidents.
