RT Journal Article SR Electronic T1 Human Exposure Assessment and Relief From Neuropsychiatric Symptoms: Case Study of a Hairdresser JF The Journal of the American Board of Family Practice JO J Am Board Fam Med FD American Board of Family Medicine SP 136 OP 141 DO 10.3122/jabfm.17.2.136 VO 17 IS 2 A1 Stephen J. Genuis A1 Shelagh K. Genuis YR 2004 UL http://www.jabfm.org/content/17/2/136.abstract AB Human exposure assessment and the results of implementing ‘precautionary avoidance’ suggested a relationship between a hairdresser’s neuropsychiatric symptoms and occupational exposure to potentially hazardous chemicals. A variety of investigations in response to patient complaints of depression, emotional instability and various physical symptoms revealed no objective abnormality; the CH2OPD2 mnemonic (community, home, hobbies, occupation, personal habits, diet and drugs) recommended by the Ontario College of Family Physicians was used as a first-line screening tool to assess potential environmental exposure to toxins. After occupational leave of absence, the patient reported cessation of symptoms. Environmental causes for familiar medical problems are frequently undiagnosed; it is recommended that, where appropriate, a screening tool for evaluation of environmental exposure to toxics be incorporated into primary care assessment and management of patients.
