Clinical Observation of 12 Farmers Who Believe Themselves to Have Suffered from Chronic Pesticide Intoxication

Abstract

Background/Aims We assessed twelve cases of suspected chronic pesticide intoxication, with medically unexplained physical symptoms. Methods Complete blood cell count (CBC), blood chemistry, routine urinalysis, chest X-ray, ECG, gastrofiberscopy, abdominal ultrasonography, neuroselective sensory nerve conduction threshold, and psychological assessment were performed on 12 farmers who believe themselves to have suffered from chronic pesticide intoxication. Results No specific abnormalities were observed on CBC, routine urinalysis, chest X-ray, ECG, gastroscopy, abdominal ultrasonography, or peripheral nerve conduction velocity test. They persistently manifested helplessness, depression, and anxiety. The results of both psychological assessment and general physical examination revealed the following clinical features: depression (8 cases), multiple chemical hypersensitivity syndrome (2 cases), alcoholism (1 case), and religious preoccupation (1 case). Conclusion In those living in the western rural area of South Korea, depression is a prominent ongoing presentation in pesticide-exposed farmers, in addition to unexplainable physical symptoms.
