Multiple chemical sensitivity. Medical search. Definitions

An acquired disorder characterized by recurrent symptoms, referable to multiple organ systems, occurring in response to demonstrable exposure to many chemically unrelated compounds at doses below those established in the general population to cause harmful effects. (Cullen MR. The worker with multiple chemical sensitivities: an overview. Occup Med 1987;2(4):655-61)

A polysymptomatic condition believed by clinical ecologists to result from immune dysregulation induced by common foods, allergens, and chemicals, resulting in various physical and mental disorders. The medical community has remained largely skeptical of the existence of this "disease", given the plethora of symptoms attributed to environmental illness, the lack of reproducible laboratory abnormalities, and the use of unproven therapies to treat the condition. (From Segen, Dictionary of Modern Medicine, 1992)

Medical specialty concerned with environmental factors that may impinge upon human disease, and development of methods for the detection, prevention, and control of environmentally related disease.

A group of symptoms that are two- to three-fold more common in those who work in large, energy-efficient buildings, associated with an increased frequency of headaches, lethargy, and dry skin. Clinical manifestations include hypersensitivity pneumonitis (ALVEOLITIS, EXTRINSIC ALLERGIC); allergic rhinitis (RHINITIS, ALLERGIC, PERENNIAL); ASTHMA; infections, skin eruptions, and mucous membrane irritation syndromes. Current usage tends to be less restrictive with regard to the type of building and delineation of complaints. (From Segen, Dictionary of Modern Medicine, 1992)

The science of controlling or modifying those conditions, influences, or forces surrounding man which relate to promoting, establishing, and maintaining health.

A group of disorders characterized by physical symptoms that are affected by emotional factors and involve a single organ system, usually under AUTONOMIC NERVOUS SYSTEM control. (American Psychiatric Glossary, 1988)

Unexplained symptoms reported by veterans of the Persian Gulf War with Iraq in 1991. The symptoms reported include fatigue, skin rash, muscle and joint pain, headaches, loss of memory, shortness of breath, gastrointestinal and respiratory symptoms, and extreme sensitivity to commonly occurring chemicals. (Nature 1994 May 5;369(6475):8)

A widely used industrial solvent.

A state in which the environs of hospitals, laboratories, domestic and animal housing, work places, spacecraft, and other surroundings are under technological control with regard to air conditioning, heating, lighting, humidity, ventilation, and other ambient features. The concept includes control of atmospheric composition. (From Jane's Aerospace Dictionary, 3d ed)

Prevalence of people reporting sensitivities to chemicals in a population-based survey. (1/104)

To describe the prevalence and correlates of reports about sensitivities to chemicals, questions about chemical sensitivities were added to the 1995 California Behavior Risk Factor Survey (BRFS). The survey was administered by telephone to 4,046 subjects. Of all respondents, 253 (6.3%) reported doctor-diagnosed "environmental illness" or "multiple chemical sensitivity" (MCS) and 643 (15.9%) reported being "allergic or unusually sensitive to everyday chemicals." Sensitivity to more than one type of chemical was described by 11.9% of the total sample population. Logistic regression models were constructed. Hispanic ethnicity was associated with physician-diagnosed MCS (adjusted odds ratio (OR) = 1.82, 95% confidence interval (CI) 1.21-2.73). Female gender was associated with individual self-reports of sensitivity (adjusted OR = 1.63, 95% CI 1.23-2.17). Marital status, employment, education, geographic location, and income were not predictive of reported chemical sensitivities or reported doctor diagnosis. Surprising numbers of people believed they were sensitive to chemicals and made sick by common chemical exposures. The homogeneity of responses across race-ethnicity, geography, education, and marital status is compatible with a physiologic response or with widespread societal apprehensions in regard to chemical exposure.

A review of multiple chemical sensitivity. (2/104)

OBJECTIVE: To review critically the scientific literature on multiple chemical sensitivity (MCS). Definitions of MCS vary but, for this review, a broad definition of MCS was adopted as symptoms in more than one organ system elicited by various unrelated chemicals at very low levels of exposure. METHODS: A systematic literature search identified several hundred references from which key papers were selected. Two questions are considered, does MCS exist and what causes MCS. RESULTS AND CONCLUSIONS: Despite extensive literature on the existence of MCS, there is no unequivocal epidemiological evidence; quantitative exposure data are singularly lacking; and qualitative exposure data are, at best, patchy. There is also some evidence to suggest that MCS is sometimes used as an indiscriminate diagnosis for undiagnosed disorders. Despite this, the collated evidence suggests that MCS does exist although its prevalence generally seems to be exaggerated. Many causal mechanisms have been proposed, some suggesting a physical origin--such as MCS reflecting an immunological overload (total body load)--others favouring a psychological basis--such as MCS symptoms being evoked as part of a conditioned response to previous trauma. The available evidence seems most strongly to support a physical mechanism involving sensitisation of part of the midbrain known as the limbic system. However, it is increasingly being recognised that the psychological milieu of a person can considerably influence physical illness, either through generating a predisposition to disease or in the subsequent prognosis. Work is needed to establish the prevalence of MCS and to confirm or refute selected causal mechanisms. (+info)

Acquisition and extinction of somatic symptoms in response to odours: a Pavlovian paradigm relevant to multiple chemical sensitivity. (3/104)

OBJECTIVES: Multiple chemical sensitivity is a poorly understood syndrome in which various symptoms are triggered by chemically unrelated, but often odorous substances, at doses below those known to be harmful. This study focuses on the process of pavlovian acquisition and extinction of somatic symptoms triggered by odours. METHODS: Diluted ammonia and butyric acid were odorous conditioned stimuli (CS). The unconditioned stimulus (US) was 7.4% CO2 enriched air. One odour (CS+) was presented together with the US for 2 minutes (CS+ trial), and the other odour (CS-) was presented with air (CS-trial). Three CS+ and three CS-exposures were run in a semi-randomised order; this as the acquisition (conditioning) phase. To test the effect of the conditioning, each subject then had one CS+ only--that is, CS+ without CO2--and one CS- test exposure. Next, half the subjects (n = 32) received five additional CS+ only exposures (extinction group), while the other half received five exposures to breathing air (wait group). Finally, all subjects got one CS+ only test exposure to test the effect of the extinction. Ventilatory responses were measured during and somatic symptoms after each exposure. RESULTS: More symptoms were reported upon exposure to CS+ only than to CS-odours, regardless of the odour type. Altered respiratory rate was only found when ammonia was CS+. Five extinction trials were sufficient to reduce the level of acquired symptoms. CONCLUSION: Subjects can acquire somatic symptoms and altered respiratory behaviour in response to harmless, but odorous chemical substances, if these odours have been associated with a physiological challenge that originally had caused these symptoms. The conditioned symptoms can subsequently be reduced in an extinction procedure. The study further supports the plausibility of a pavlovian conditioning hypothesis to explain the pathogenesis of MCS.

A 37-year-old mechanic with multiple chemical sensitivities. (4/104)

A 37-year-old heating, ventilation, and air-conditioning mechanic developed respiratory, musculoskeletal, and central nervous system symptoms associated with a variety of odorous environmental chemicals. Organic disease was not evident, but the patient was distressed by these symptoms and was at risk for becoming disabled by them. His symptoms fit broadly into the condition recognized as multiple chemical sensitivity. Multiple chemical sensitivity is a diagnostic term for a group of symptoms without demonstrated organic basis. The symptoms are characteristic of dysfunction in multiple organ systems, they increase and decrease according to exposure to low levels of chemical agents in the patient's environment, and they sometimes occur after a distinct environmental change or insult such as an industrial accident or remodeling. Although traditional medical organizations have not agreed on a definition for this syndrome, it is being increasingly recognized and makes up an increasing percentage of the caseload at occupational and environmental medicine clinics. Although there is often dispute about whether the symptoms have a functional or organic basis, an informed approach to evaluation, diagnosis, and management and a careful assessment of impairment, disability, and work relatedness are necessary. Careful exclusion of organic causes is critical, and this should be followed by a judicious approach to coping with symptoms. (+info)

Model development and research vision for the future of multiple chemical sensitivity. (5/104)

Multiple chemical sensitivity (MCS) is characterized by heightened self-reported sensitivity to extremely low concentrations of chemicals. It has numerous symptoms in common with the sick building syndrome, the Gulf War syndrome, and chronic fatigue. Despite much research, reproducible objective findings are lacking for MCS, as is a sound model to explain it. This paper proposes a 2-step model combining the needed epidemiologic terminology with that of psychophysiological activation and sensitization. It is suggested that different environmental stressors act as initiators. After initiation, the limbic system and other parts of the brain become sensitized and hyperreactive to environmental triggers. Odor acts as one important trigger. Future research should use more biological assessments in combination with environmental and psychosocial data and involve patient groups with similar symptoms, although diagnosed as suffering from different entities. The similarities and differences of patients with such entities need to be understood before the entities themselves can be understood, diagnosed, treated, and prevented. (+info)

Psychological test performance during experimental challenge to toluene and n-butyl acetate in cases of solvent-induced toxic encephalopathy. (6/104)

OBJECTIVES: This study determined whether performance in neurobehavioral tests deteriorates during subjectively annoying chemical challenge below known neurotoxic thresholds among persons with toxic encephalopathy with subjective hypersensitivity to chemicals. METHODS: Subjects with symptoms and previous neuropsychological test results compatible with toxic encephalopathy (TE) of either type 2A (N=12) or 2B (N=12) and unexposed referents (N=12) were challenged in an exposure chamber. In a counterbalanced design, the subjects were exposed on 2 occasions to increasing air concentrations of n-butyl acetate and toluene at levels well below the thresholds for neurotoxic effects. Attention and motor speed tests were given (i) in room air outside the chamber before the challenge, (ii) in room air inside the chamber before the exposure, (iii) at 12 ppm (44 or 56 mg/m3), and (iv) at 48 ppm (at 180 or 228 mg/m3). RESULTS: For both substances the TE groups showed a slight increase (deterioration) in the simple reaction-time task during chemical exposure, but not in the complex reaction-time task or in the digit symbol test of the Wechsler Adult Intelligence Scale. Contrary to reference subjects, the TE subjects did not show any improvement or learning effect in the digit symbol test over the chamber phases. n-Butyl acetate tended to affect cognitive functioning more obviously than toluene did. Suggestion or expectancy effects were not observed in any group in the clean-air baseline conditions. CONCLUSIONS: The results do not support the notion that men with subjective hypersensitivity to chemicals would be more affected than healthy men regarding cognitive functioning during annoying solvent exposure below thresholds for acute neurotoxic effects.

Reproducibility of the University of Toronto self-administered questionnaire used to assess environmental sensitivity. (7/104)

Environmental sensitivity patients report symptoms provoked by low-level exposure to a wide range of substances. Features of published case definitions include nature of onset, chronicity, symptom provocation by multiple substances, symptom provocation by an escalating number of exposures, involvement of multiple body systems including the nervous system, provocation by unrelated substances, and addictive behaviors. This study assessed the reproducibility of a Canadian self-administered questionnaire, the University of Toronto Health Survey, designed to determine the prevalence of the features described in these case definitions. A total of 191 eligible respondents aged 16-70 years who attended several types of medical practices in 1994 were invited to complete a second questionnaire 5-7 months after the first; 134 (70.2%) complied. Total agreement on whether patients satisfied each of seven case definitions ranged from 80% to 90%. After adjustment for chance, major agreement was observed for three of the seven case definitions (kappa = 0.69, 0.68, and 0.78). The survey achieved good reproducibility regarding self-report of symptoms described in published case definitions of environmental sensitivity. (+info)

A 4-year-old girl with manifestations of multiple chemical sensitivities. (8/104)

Multiple chemical sensitivities (MCS) syndrome, also known as idiopathic environmental intolerance, is a controversial diagnosis that encompasses a wide range of waxing and waning, subjective symptoms referable to more than one body system and provoked by exposure to low levels of chemicals, foods, or other agents in the environment. Although MCS has been studied extensively, a unifying mechanism explaining the illness remains obscure, and clinicians are divided as to whether such a medical entity exists separately from psychosomatic syndromes. MCS is an adult diagnosis; there is little reference to pediatric cases in the scientific literature. In this case from the Pediatric Environmental Health Subspecialty Unit at Boston's Children's Hospital, I present the case of a preschool child who had suffered from milk allergy and poor weight gain as an infant, and then later developed asthma, allergic symptoms, sinusitis, headaches, fatigue, and rashes precipitated by an expanding variety of chemicals, foods, and allergens. I review definitions, mechanisms, diagnostic strategies, and management, and discuss some uniquely pediatric features of MCS as illustrated by this case. (+info)

Multiple Chemical Sensitivity (MCS), also known as Idiosyncratic Intolerance, is a chronic condition characterized by symptoms that the affected person attributes to low-level exposure to chemicals in the environment. These reactions are not part of a recognized allergic response and are often delayed in onset.

The American Academy of Allergy, Asthma & Immunology (AAAAI) defines MCS as: "A heightened sensitivity to chemicals that most people tolerate well... Symptoms can include headache, fatigue, difficulty concentrating, confusion, joint pain, and digestive disturbances."

However, it's important to note that the medical community has not reached a consensus on the definition, cause, or diagnosis of MCS. Some healthcare providers question its validity as a distinct medical entity due to lack of consistent scientific evidence supporting the relationship between exposure levels and symptoms.

Environmental Illness (EI) is a condition in which individuals report experiencing various symptoms that they believe are caused or worsened by exposure to specific environmental factors. These factors can include chemicals, allergens, pollutants, or other substances present in the air, water, or food. The symptoms of EI can vary widely and may include headaches, fatigue, difficulty concentrating, respiratory problems, skin irritations, and gastrointestinal issues.

It's important to note that while some people may be more sensitive than others to environmental factors, the term "Environmental Illness" is not recognized as a formal medical diagnosis by major medical organizations such as the American Medical Association or the World Health Organization. Instead, the symptoms of EI are often attributed to other conditions, such as allergies, asthma, or chemical sensitivities.

In some cases, individuals with EI may be diagnosed with a related condition called Multiple Chemical Sensitivity (MCS), which is characterized by heightened sensitivity to chemicals and other environmental factors. However, MCS is also not recognized as a formal medical diagnosis by many major medical organizations.

Overall, while some people may experience symptoms that they believe are caused by exposure to environmental factors, it's important to consult with a healthcare provider for an accurate diagnosis and treatment plan.

Environmental medicine is a branch of medicine that focuses on the study of how various environmental factors, including physical, chemical, and biological agents, can impact human health. It involves understanding and addressing the causes and effects of environmental exposures on individual health and disease. This may include assessing and managing exposure to pollutants, allergens, infectious agents, and other environmental stressors in order to prevent or treat related health issues. Additionally, environmental medicine also considers how individual susceptibility, such as genetic factors or pre-existing health conditions, can influence the impact of environmental exposures on health.

Sick Building Syndrome (SBS) is not a universally accepted medical diagnosis, but it is a term used by the World Health Organization (WHO) to describe situations where building occupants experience acute health and comfort effects that seem to be linked to time spent in a building, without any specific illness or cause being identified.

The symptoms of SBS may include:

* Eye, nose, or throat irritation
* Headaches
* Dry cough
* Dry or itchy skin
* Dizziness and nausea
* Fatigue
* Difficulty concentrating
* Sensory irritability

These symptoms usually disappear after leaving the building. The causes of SBS are not well understood, but they are often attributed to inadequate ventilation, chemical contaminants from indoor or outdoor sources, biological contaminants such as mold or bacteria, and physical factors such as lighting, noise, or extremes of temperature or humidity.

It is important to note that the symptoms of SBS can also be caused by other factors, so it is essential to consult with a healthcare professional if you experience any of these symptoms. A thorough investigation of the building and its environment may also be necessary to identify potential causes and solutions.

Environmental health is a branch of public health that focuses on the study of how environmental factors, including physical, chemical, and biological factors, impact human health and disease. It involves the assessment, control, and prevention of environmental hazards in order to protect and promote human health and well-being.

Environmental health encompasses a wide range of issues, such as air and water quality, food safety, waste management, housing conditions, occupational health and safety, radiation protection, and climate change. It also involves the promotion of healthy behaviors and the development of policies and regulations to protect public health from environmental hazards.

The goal of environmental health is to create safe and healthy environments that support human health and well-being, prevent disease and injury, and promote sustainable communities. This requires a multidisciplinary approach that involves collaboration between various stakeholders, including policymakers, researchers, healthcare providers, community organizations, and the public.

Psychophysiologic Disorders, also known as psychosomatic disorders, refer to a category of mental health conditions where psychological stress and emotional factors play a significant role in causing physical symptoms. These disorders are characterized by the presence of bodily complaints for which no physiological explanation can be found, or where the severity of the symptoms is far greater than what would be expected from any underlying medical condition.

Examples of psychophysiologic disorders include:

* Conversion disorder: where physical symptoms such as blindness, paralysis, or difficulty swallowing occur in the absence of a clear medical explanation.
* Irritable bowel syndrome (IBS): where abdominal pain, bloating, and changes in bowel habits are thought to be caused or worsened by stress and emotional factors.
* Psychogenic nonepileptic seizures (PNES): where episodes that resemble epileptic seizures occur without any electrical activity in the brain.
* Chronic pain syndromes: where pain persists for months or years beyond the expected healing time, often accompanied by depression and anxiety.

The diagnosis of psychophysiologic disorders typically involves a thorough medical evaluation to rule out other potential causes of the symptoms. Treatment usually includes a combination of psychotherapy, such as cognitive-behavioral therapy (CBT), relaxation techniques, stress management, and sometimes medication for co-occurring mental health conditions.

I'm sorry for any confusion, but "Persian Gulf Syndrome" is not a widely recognized or officially defined medical condition. The term has been used informally to describe various nonspecific symptoms such as fatigue, cognitive problems, and muscle pain reported by some military personnel who served in the Persian Gulf region. However, these symptoms are common and can be caused by many different factors, so it's not clear that they are related to service in the Persian Gulf.

The Department of Veterans Affairs (VA) recognizes "Persian Gulf War Veterans' Illnesses" as a category of unexplained illnesses that some veterans of the 1990-1991 Gulf War experience. This includes conditions such as chronic fatigue syndrome, fibromyalgia, and functional gastrointestinal disorders, among others. But it's important to note that these are recognized diseases with specific diagnostic criteria, not a single syndrome.

If you or someone else is experiencing persistent health issues that may be related to military service, it's recommended to consult with a healthcare provider. They can provide a thorough evaluation and help determine if the symptoms are related to service or some other cause.

Toluene is not a medical condition or disease, but it is a chemical compound that is widely used in various industrial and commercial applications. Medically, toluene can be relevant as a substance of abuse due to its intoxicating effects when inhaled or sniffed. It is a colorless liquid with a distinctive sweet aroma, and it is a common solvent found in many products such as paint thinners, adhesives, and rubber cement.

In the context of medical toxicology, toluene exposure can lead to various health issues, including neurological damage, cognitive impairment, memory loss, nausea, vomiting, and hearing and vision problems. Chronic exposure to toluene can also cause significant harm to the developing fetus during pregnancy, leading to developmental delays, behavioral problems, and physical abnormalities.

"Controlled Environment" is a term used to describe a setting in which environmental conditions are monitored, regulated, and maintained within certain specific parameters. These conditions may include factors such as temperature, humidity, light exposure, air quality, and cleanliness. The purpose of a controlled environment is to ensure that the conditions are optimal for a particular activity or process, and to minimize the potential for variability or contamination that could affect outcomes or results.

In medical and healthcare settings, controlled environments are used in a variety of contexts, such as:

* Research laboratories: To ensure consistent and reproducible experimental conditions for scientific studies.
* Pharmaceutical manufacturing: To maintain strict quality control standards during the production of drugs and other medical products.
* Sterile fields: In operating rooms or cleanrooms, to minimize the risk of infection or contamination during surgical procedures or sensitive medical operations.
* Medical storage: For storing temperature-sensitive medications, vaccines, or specimens at specific temperatures to maintain their stability and efficacy.

Overall, controlled environments play a critical role in maintaining safety, quality, and consistency in medical and healthcare settings.

Multiple chemical sensitivity (MCS), also known as idiopathic environmental intolerances (IEI), is an unrecognized and controversial diagnosis characterized by chronic symptoms attributed to exposure to low levels of commonly used chemicals. (wikipedia.org)
Although these symptoms can be debilitating, MCS is not recognized as an organic, chemical-caused illness by the World Health Organization, American Medical Association, nor any of several other professional medical organizations. (wikipedia.org)
the existence and severity of symptoms is seemingly related to the perception that a chemical stimulus is present. (wikipedia.org)
There is a general agreement among most MCS researchers that the cause is not specifically related to sensitivity to chemicals, but this does not preclude the possibility that symptoms are caused by other known or unknown factors. (wikipedia.org)
Multiple chemical sensitivity can include a wide range of symptoms, which some people link to their environment. (webmd.com)
Others say that the symptoms stem from an extreme sensitivity to certain smells. (webmd.com)
Or they may link their symptoms to contact with low levels of chemicals at work, such as if their office has poor ventilation. (webmd.com)
Some learn from experience that certain foods or chemicals seem to make their symptoms worse. (webmd.com)
MCS differs from the common scientific understanding of illness because the condition is always manifested by multiple non-specific symptoms from different organs at the same time and because these symptoms may occur after exposure to chemicals at very low concentrations. (ohsrep.org.au)
People with MCS suffer from migraines, muscle pain, rashes, nausea, fatigue, and other debilitating symptoms they believe to be caused by low-level exposure to chemicals such as laundry detergent, perfume, and car exhaust. (slate.com)

When human illness results from an unintentional or intentional release of a toxin (chemicals produced by metabolism in an organism [e.g., ricin]) or a toxicant (natural or synthetic chemicals not metabolically produced by an organism [e.g., nerve agents]) into the environment, uniform reporting is necessary to direct appropriate resources, assess the extent of morbidity and mortality, track poisoned persons, and monitor response to intervention. (cdc.gov)
In this report, CDC presents case definitions to facilitate uniform reporting among local, state, and federal public health agencies of illness resulting from a chemical release. (cdc.gov)
When illness results from an intentional or unintentional chemical release (either known or suspected on the basis of a credible threat) into the environment, uniform reporting is paramount to direct appropriate resources, assess the extent of morbidity and mortality, track poisoned persons, and monitor response to intervention.
