[Intermediary syndrome in acute malathion poisoning].
BACKGROUND
Acute poisoning by an organophosphorus insecticide is frequently observed in Morocco. We report a case of malathion poisoning complicated by an intermediate syndrome.


METHODS
A 42-year-old woman was hospitalized 3 hours after ingestion of 50 g of malathion. Intubation and ventilatory assistance was required due to failing consciousness and bronchial plugging. On day 4, a neurological syndrome suggestive of the intermediary syndrome with diaphragmatic palsy made it necessary to continue ventilatory assistance to day 20.


CONCLUSIONS
The intermediary syndrome occurs 24 to 96 hours after the acute cholinergic phase of organophosphorus poisoning. It consists of an exclusive neuromuscular involvement. The intermediate syndrome is confined to an abnormality of neuromuscular function in specific muscle groups: proximal limb muscles, neck flexors, motor cranial nerves and respiratory muscles, with difficult weaning from respiratory assistance. The intermediary syndrome is quite uncommon. The risk of respiratory failure emphasizes the need for close monitoring in an intensive care setting for at least 96 hours, depending on the intensity of the cholinergic syndrome.
