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.
