The essential features of treatment for chemical sensitivity are: 1) Encouraging the provision of clean air, food, water, and surroundings. 2) Identifying substances to which the patient is sensitive, with subsequent a) enhanced avoidance, or b) specific immunotherapy to reduce the patient's reactivity to those substances. 3) Assessing and enhancing the(More)
Although no one has all the answers to the mystery of chemical sensitivity, the reality of this condition, most recently called multiple chemical sensitivities, is not in doubt. Evidence is increasing of its possible physiologic mechanisms, which will be discussed later in this volume. From the evidence and from personal and professional experience, the(More)
The subset of patients reporting chemical sensitivity with neurocognitive complaints usually exhibits specific abnormalities of brain metabolism consistent with neurotoxicity, on imaging with single photon emission computed tomography (SPECT). These recurrent neurotoxic patterns are characterized by a mismatch in tracer uptake between early- and late-phase(More)
BACKGROUND The medical literature reports health hazards for law enforcement personnel from repeated exposure to methamphetamine and related chemical compounds. Most effects appear transitory, but some Utah police officers with employment-related methamphetamine exposures developed chronic symptoms, some leading to disability. This report is of an(More)
Chemical sensitivities display a recurrent pattern on scintigraphic examinations of the brain. The pattern can include mismatching between early and late imaging, multiple hot and cold foci distributed throughout the cortex without regard to lobar distribution (salt and pepper pattern), temporal asymmetries, and sometimes increased activity in the basal(More)
Fifty chemically sensitive patients with vascular, asthmatic and arthritic signs, ranging in age from 21 to 61, were exposed to double-blind challenges of ambient doses of inhaled toxic chemicals in a specially designed booth in an Environmental Control Unit (ECU). Primary signs and symptoms were recorded before and after challenge with five chemicals and(More)
By the nature of their work environment, physicians may be exposed to potentially toxic substances that can trigger chemical sensitivity. Nineteen physicians with chemical sensitivity were evaluated at the Environmental Health Center - Dallas regarding: type of specialty, history of chemical exposure, symptoms produced, food and water tolerance, immune(More)
Susceptibility to environmental incitants such as air, food and water components is becoming an increasingly recognized health problem. These sensitivities and reactions can induce a spectrum of symptoms affecting smooth muscle, mucous membranes and collagen in the respiratory, gastrointestinal, genitourinary and vascular systems. These reactions may be(More)
Mycotoxins have compromising effects on varied biological systems, even when ingested at levels which do not evoke manifestations of clinical mycotoxicoses. No data have been previously found as to the therapeutic and mitogenic effects of mycotoxins. This was the objective of the present work. Human peripheral T4 lymphocytes were obtained by venipuncture,(More)
