Do Inhaled Pesticides Cause Dystonic Reactions? Case Report from a Paediatric Emergency Room

Dystonia is a movement disorder in which intermittent muscle contractions cause twisting, repetitive-abnormal movements, or postures. It can be inherited or acquired. Intoxication also plays a role in aetiology. In this report, we describe two siblings who presented to the paediatric emergency room with acute dystonia after 5-10 minutes of pesticide exposure via inhalation. The clinical symptoms of the patients with suspected acute dystonia were controlled with biperiden. Pesticides containing permethrin, tetramethrin, and cypermethrin can cause acute dystonic reactions even with short-term exposure via inhalation.
