Asthma: A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).Anti-Asthmatic Agents: Drugs that are used to treat asthma.Asthma, Exercise-Induced: Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it).Administration, Inhalation: The administration of drugs by the respiratory route. It includes insufflation into the respiratory tract.Peak Expiratory Flow Rate: Measurement of the maximum rate of airflow attained during a FORCED VITAL CAPACITY determination. Common abbreviations are PEFR and PFR.Asthma, Occupational: Asthma attacks caused, triggered, or exacerbated by OCCUPATIONAL EXPOSURE.Forced Expiratory Volume: Measure of the maximum amount of air that can be expelled in a given number of seconds during a FORCED VITAL CAPACITY determination . It is usually given as FEV followed by a subscript indicating the number of seconds over which the measurement is made, although it is sometimes given as a percentage of forced vital capacity.Bronchial Hyperreactivity: Tendency of the smooth muscle of the tracheobronchial tree to contract more intensely in response to a given stimulus than it does in the response seen in normal individuals. This condition is present in virtually all symptomatic patients with asthma. The most prominent manifestation of this smooth muscle contraction is a decrease in airway caliber that can be readily measured in the pulmonary function laboratory.Bronchodilator Agents: Agents that cause an increase in the expansion of a bronchus or bronchial tubes.Respiratory Sounds: Noises, normal and abnormal, heard on auscultation over any part of the RESPIRATORY TRACT.Allergens: Antigen-type substances that produce immediate hypersensitivity (HYPERSENSITIVITY, IMMEDIATE).Adrenal Cortex HormonesHypersensitivity: Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.Hypersensitivity, Immediate: Hypersensitivity reactions which occur within minutes of exposure to challenging antigen due to the release of histamine which follows the antigen-antibody reaction and causes smooth muscle contraction and increased vascular permeability.Respiratory Function Tests: Measurement of the various processes involved in the act of respiration: inspiration, expiration, oxygen and carbon dioxide exchange, lung volume and compliance, etc.Rhinitis: Inflammation of the NASAL MUCOSA, the mucous membrane lining the NASAL CAVITIES.Albuterol: A short-acting beta-2 adrenergic agonist that is primarily used as a bronchodilator agent to treat ASTHMA.

In the case of two treatments, A and B, half the subjects are randomly allocated to receive these in the order A, B and half to receive them in the order B, A. A criticism of this design is that effects of the first treatment may carry over into the period when the second is given. (Last, A Dictionary of Epidemiology, 2d ed)
Direct costs of occupational asthma due to sensitization in Quebec (1988 to 2002): revisited. (1/37)BACKGROUND: In a previous study, the authors assessed direct costs for occupational asthma (OA) in a random sample of eight to 10 accepted claims per year for OA between 1988 and 2002. Compensation for loss of income (CLI) was found to be significantly higher for men and for OA caused by low-molecular-weight agents. OBJECTIVES AND METHODS: To identify sociodemographic factors that modulate CLI, the dossier of each claimant in the previous study was re-examined. RESULTS: Higher CLI costs were directly related to the duration of CLI (over which loss of income was reimbursed) (r=0.65). Costs of CLI were higher in patients 30 years of age or older at diagnosis, married subjects and individuals who were offered early retirement or were enrolled in an active interventional rehabilitation program. Higher CLI costs in men, but not in women, were associated with the following sociodemographic factors: older age, different rehabilitation program (early retirement and active program versus no specific program) and married status. Older age was found to be significant in the multivariate analysis performed for men. The cost of CLI was higher in workers with OA caused by low-molecular-weight agents. Although proportionally fewer men and younger workers were affected with OA caused by low-molecular-weight agents, the longer duration of CLI for this category of agent could explain the higher costs. CONCLUSION: Higher costs for CLI were associated in men (but not women) with older age, married status and type of rehabilitation program (early retirement and active rehabilitation). Higher costs of CLI for OA caused by low-molecular-weight agents were associated with a longer duration of CLI per se, and not with sociodemographic factors. (+info)
Barriers to the recognition and reporting of occupational asthma by Canadian pulmonologists. (2/37)BACKGROUND: Occupational asthma is a common, but probably under-recognized problem. OBJECTIVE: To identify the factors that suggest work-related asthma when a pulmonologist encounters an adult patient with new-onset asthma, and to identify the barriers to recognizing and reporting such cases. METHODS: A postal questionnaire was sent to all pulmonologists in Canada. The questionnaire asked participants to respond to several questions about recognizing, diagnosing and reporting occupational asthma. Answers were scored using visual analogue scales. RESULTS: A total of 201 eligible responses were received from 458 pulmonologists. Pulmonologists identified that the most important factor in initially considering the role of work in occupational asthma was having seen others affected at the same workplace, or exposed to the same agent. Important perceived barriers to considering a diagnosis of occupational asthma were physicians' low awareness, lack of knowledge and time. The most important barriers to reporting cases were the pulmonologists' perceived patient concerns regarding job security and income. Quebec pulmonologists generally perceived barriers to recognizing and reporting occupational asthma to be less important, and believed that the use of specific inhalation challenge was more important in considering a diagnosis. CONCLUSIONS: Pulmonologists most readily recognized occupational asthma caused by a substance or process that they previously encountered as a possible cause of asthma. Time constraints and knowledge may hamper their ability to recognize occupational asthma. Concerns regarding the effect of the diagnosis on the patient's job and income may discourage reporting.

Background: The links between asthma and rhinitis are nowadays referred to as the united airways disease (UAD). Current evidence shows that the UAD model seems to be applicable to occupational rhinitis (OR) and occupational asthma (OA). Objective: We aimed to objectively assess, in the context of specific inhalation challenge (SIC) testing, the concomitance of bronchial and nasal reaction in the investigation of OR and OA Methods: Forty-three subjects with a history of work-related asthma symptoms underwent SIC for confirmation of OA and investigation of OR. Subjects underwent assessment of changes in bronchial calibre by spirometry and assessment of nasal patency and airway inflammation by acoustic rhinometry and nasal lavage. Results: A positive nasal challenge was observed in 25 SIC whereas a positive bronchial challenge was observed in 17 SIC. A concomitant positive nasal and bronchial challenge was observed in 13 instances. This association was significant (risk ratio= 1.7; 95% CI=1.0 to ...
Work-related asthma (WRA) includes work-exacerbated asthma (preexisting or concurrent asthma worsened by factors related to the workplace environment) and occupational asthma (new onset asthma attributed to the workplace environment) (1,2). WRA is a preventable occupational lung disease associated with serious adverse health and socioeconomic outcomes (1,2). Among workers with similar occupational
Sensitizer-induced occupational asthma immunologic form of asthma which occurs due to inhalation of specific substances (i.e., high-molecular-weight proteins from plants and animal origins, or low-molecular-weight agents that include chemicals, metals and wood dusts) and occurs after a latency period of several weeks to years.. Irritant-induced (occupational) asthma is a non-immunologic form of asthma that results from a single or multiple high dose exposure to irritant products. It is usually develops early after exposure; however can also develop insidiously over a few months after a massive exposure to a complex mixture of alkaline dust and combustion products, as shown in the World Trade Center disaster. Unlike those with sensitizer-induced occupational asthma, subjects with irritant-induced occupational asthma do not develop work-related asthma symptoms after re-exposure to low concentrations of the irritant that initiated the symptoms. Reactive airways dysfunction syndrome (RADS) is ...
According to the California Work-Related Asthma Prevention Program, part of the Occupational Health Branch of California Department of Public Health, cleaning products used in workplaces can cause or trigger work-related asthma. To prevent harsh affects of cleaning products, employers should make sure the safest products and practices are used in the workplace. The program has found that nearly 10 percent of all work-related asthma cases were caused by exposure to cleaning products. Most of these cases had new asthma that started only after they began work - the exposures caused their asthma. About one in five people (almost 20 percent) used cleaning products directly, such as janitors. The other 80 percent of workers attributed their asthma symptoms to cleaning products used nearby. Many workplaces, like schools, hospitals, and restaurants are places where everyone, including children, can be affected by cleaning products. How can asthma from cleaning products be prevented? ...

Occupational asthma (OA) is steadily emerging as the principal cause of respiratory disease due to the workplace environment. One of the key means to ascertain diagnosis of OA is specific inhalation challenge (SIC) with occupational agents. This review: 1) describes the methodology of SIC, with a special emphasis on procedures aimed at increasing the safety and validity of these tests; and 2) outlines the roles of SIC in the diagnosis of OA in clinical and medicolegal assessment, epidemiological studies, surveillance programmes and the investigation of the pathophysiological mechanisms of asthma and OA. We discuss areas of future development, including the development of apparatus which allows exposure of subjects to low and stable concentrations of the occupational agent and the assessment of preventive procedures.. ...
Work-related asthma includes work aggravation of preexisting asthma and new-onset asthma induced by occupational exposure.. To identify cases of asthma related to the occupational exposure, assess the severity and control of asthma at work and appreciate the consequences on employment, we conducted a cross-sectional study involving all active asthmatic patients who had consulted the pulmonology department of the University Hospital of Sfax in Tunisia for a period of four months.. We collected the records of 104 patients. The group of elementary occupations was 69.2%. Workers in the textile and food industry represented 16.3% and 15.4% respectively. Symptoms appear in the first ten years of occupational exposure in 39.4% of cases. The asthma was 31.7% partially controlled and uncontrolled in 7.7% of cases. The professional investigation had concluded that the occupational origin of asthma represented 44.2% of patients and the worsening by the professional environment 28.8% of cases. The ...

Mounting evidence suggests that diisocyanates are able to bind airway epithelial cell proteins, resulting in airway inflammation with cytokine and chemokine production and cellular recruitment . The toxicity of diisocyanates toward airway epithelial tissues has also been reported, and MDI and HDI prepolymers were shown to induce airway epithelial barrier dysfunction that was partly associated with altered glutamine levels [30, 31]. The effect of TDI on the expression of lung cytokine P450 enzymes has also been documented . We attempted to culture human bronchial epithelial cells, Beas-2B, with TDI-HSA conjugates to identify the source of the IL-8 detected in the sputum of TDI-induced asthma patients . The production of IL-8 and regulated upon activation in normal T cell expressed, and secreted (RANTES) was significantly increased in a dose-dependent manner after exposure to a peripheral mononuclear cell culture supernatant derived from a TDI-induced asthma patient, and this effect ...
Immediate hypersensitivity reactions ranging from mild urticaria to life threatening anaphylaxis after exposure to natural rubber latex have been reported frequently in health care workers while occupational asthma due to latex exposure is less well studied. The results of specific challenge tests and immunological tests in four health care workers with work related respiratory and skin disorders induced by the use of latex gloves are described. Occupational asthma was confirmed in three subjects by specific challenge tests. All had a positive skin test reaction to the latex extract; specific IgE antibodies were detected in only one subject. The fourth subject had a negative specific inhalation and skin test reaction to the latex extract. Peak expiratory flow monitoring at work and away from work showed a pattern consistent with work related asthma. These findings confirm that latex is a cause of occupational asthma in health care workers.. ...

BACKGROUND:. Respiratory diseases are strongly related with exposure in the workplace. A considerable proportion of adult onset asthma is associated with these exposures. The importance of occupational risk factors for asthma has been underestimated, particularly among women. The occupational asthma study (ECRHS-OA) forms part of a wider international multicentre survey on respiratory health (European Community Respiratory Health Survey-ECRHS). The first phase of the ECRHS was conducted in 1991/92 and examined risk factors for asthma and atopy in subjects aged 20-44 years. The study updated (ECRHS-II), following-up approximately 17,000 young adults from 12 countries (Australia, Belgium, France, Germany, Iceland, Italy, Norway, Spain, Sweden, Switzerland, UK and USA).. The study provided valid and precise estimates on the importance of specific occupations, industries and exposures in relation to asthma incidence and prevalence, similar estimates for other respiratory symptoms and diseases and ...

With the reduction in the disease burden from the pneumoconioses in recent years, especially in developed countries, occupational asthma has emerged as the occupational lung disease of greatest importance. It is usually the most common respiratory condition reported in occupational disease surveillance programmes and makes a substantial contribution to the burden of asthma in the community, with an estimated population attributable risk of 15% and estimated annual cost to the USA of $US1.6 billion.1 Therefore, the introduction of prevention strategies to reduce the impact of occupational asthma, should be strongly supported.. The editorial by Snashall in this issue2 describes the latest proposal by the Health and Safety Commission (HSC) to reduce the incidence of occupational asthma in the United Kingdom.3 This article acknowledges the limited success of past HSC prevention programmes. The proposed Strategy has five components corresponding to the key programmes in Securing health together, the ...
Occupational asthma is an occupational lung disease and a type of asthma. Like other types of asthma, it is characterized by airway inflammation, reversible airways obstruction, and bronchospasm, but it is caused by something in the workplace environment. Symptoms include shortness of breath, tightness of the chest, nasal irritation, coughing and wheezing. The first person to use it in reference to a medical condition was Hippocrates, and he believed that tailors, anglers and metalworkers were more likely to be affected by the disease. Although much research has been done since, the inflammatory component of asthma was recognized only in the 1960s. Hypersensitivity pneumonitis is a related condition, with many occupational examples (e.g. flock workers lung, farmers lung, and indium lung). However, although overlapping in many cases, hypersensitivity pneumonitis may be distinguished from occupational asthma in that it isnt restricted to only occupational exposure, and involves type III ...
Sensitization: plastics (TDI and MDI), car paints (HDI and IPDI), polyurethanes (TDI), casting/melts and glues (MDI). Exposure; purely via the airways, may induce cutaneous sensitisation even in the absence of any contact with the skin. Isocyanate induced asthma (particularly TDI) is characterized by lymphocyte activation and secretion of pro-inflammatory cytokines. After exposure has ceased, a "remodelling" of the airways persists. The realisation of the problems associated with TDI, MDI and HDI, etc has led the industries to use oligomers with high molecular weights (BIC) with the aims of reducing the risks of sensitization. The norms for tolerable levels of these monomers are not sufficient to prevent work-related asthma. No norms have been fixed for polyisocyanates or polymer precursors. The response to TDI is regulated by the MHC class II loci DQA1 and DQB1. Fire retardants contain polyurethanes. A Swedish study performed in 2001 demonstrated that above 300°C these polyurethanes degrade ...

The present case of fatal asthma attack was due to acute exacerbation of work-related asthma that developed in a plastic injection process worker with a history of asthma in remission. The deceased patient led a normal life without manifestations of asthma symptoms or any treatments. However, he began to exhibit typical late-stage asthma symptoms 4 years after working with injection process simulation. Unaware of the occupational cause of those symptoms, he continued to work and finally succumbed to an asthma attack.. Occupational asthma is classified as sensitizer- or irritant-induced asthma depending on the presence or absence of sensitization and a latency period. Sensitizer-induced asthma occurs as a result of immunologic sensitization and is preceded by a latency period after exposure to asthma-triggering substances in the workplace . The latency period between exposure to the causative substances and manifestations of symptoms may range from several weeks to years depending on the phase ...

Occupational asthma from nickel sensitivity was confirmed in a male worker (SB) by allergy skin tests and inhalational challenge. In an ammonium sulphate coprecipitation test 63Ni was selectively precipitated from SB plasma indicating antibody with nickel related specificity. Preincubation of 63Ni with human serum albumin (HSA) increased the specificity of the coprecipitation test. Blocking experiments with nickel and copper(II) salts effectively inhibited the binding of 63Ni to antibody of SB plasma but did not affect control tests or that for antibodies to an unrelated antigen, ampicillin. Co2+ slightly inhibited the binding of 63Ni, while Zn2+ and Mn2+ failed to inhibit. This deactivation pattern corresponds to the known sequence of binding of these metals to the primary copper binding site of HSA. It is concluded that the antigenic determinant depends on the combination of Ni2+ with HSA at this specific copper/nickel plasma transport site.. ...
The INTEROCC project is a large-scale multinational brain tumour case-control study, conducted in seven countries (Table 2) included in INTERPHONE. The objective of INTEROCC is to address outstanding questions concerning occupational agents in the disease. Estimates of chemical and ELF exposures were determined for INTEROCC participants, and a number of manuscripts are currently submitted or in preparation that focus on risk of brain tumours in relation to such exposures. However, while the occupational part of the INTERPHONE questionnaire included source based questions to identify subjects with likely substantial exposures to EMF, this work has not yet been exploited and exposure assessment in INTEROCC to date has been based solely on job titles (i.e. linking job titles to estimates of chemical and ELF exposure based on updates of existing JEMs), with the possibility of exposure misclassification since subjects with the same job title may actually have vastly different exposure ...

MicroRNAs are small non-coding RNAs that regulate gene expression at the post-transcriptional level. While they have been implicated in various diseases, the profile changes in allergen inhalation challenge are not clarified in human. We aimed to evaluate changes in the microRNA profiles in the peripheral blood of asthmatic subjects undergoing allergen inhalation challenge. Seven mild asthmatic subjects participated in the allergen inhalation challenge. In addition, four healthy control subjects (HCs) were recruited. MicroRNA profiles in peripheral blood samples (pre-challenge and 2 hours post-challenge) were measured by the NanoString nCounter assay to determine changes in miRNA levels as these asthmatic subjects underwent an allergen inhalation challenge. One common miRNA, miR-192, was significantly expressed in both comparisons; HCs vs. pre-challenge and pre- vs. post-challenge, showing that miR-192 was significantly under-expressed in asthmatics compared to HCs and decreased in post-challenge at an

A-amylase is a starch-cleaving enzyme which is used as a flour additive in the baking industry. It is product of Aspergillus oryzae. Flour for bread making must also contain an optimum level of a-amylases. a-amylases are enzymes responsible for the conversion of starch to maltose which is further broken down to form glucose - the sugar required for effective fermentaion of the yeast. If the concentration of a-amylases is too low, too little maltose will be formed and the bread will not rise sufficiently. Too much a-amylase and bread can end up as â€˜stickyâ€™ as a result of substances called dextrins forming .. Inhalation of dust from different enzymes can be the cause of occupational asthma in exposed workers. Enzymes from different sources are being increasingly used in food. Few cases of food allergy to alpha-amylase induced by eating bread have been reported. Those cases were reported in bakery-related patients and in a pharmaceutical-industry worker ..

The three main components of wood, namely, cellulose, hemicellulose, and lignin, can be used in various areas. However, since lignin covalently crosslinks with wood polysaccharides creating networks that is an obstacle for extraction, direct extraction of different wood components in high yield is not an easy matter. One potential approach to overcome such obstacles is to treat the wood with specific enzymes that degrade the networks by specific catalysis. However, the structure of wood is so compact that the penetration of the wood fibers by large enzyme molecules is hindered. Thus, the pretreatment of wood prior to the application of enzymes is necessary, for "opening" the structure.. One pretreatment method that was performed in this thesis is based on kraft pulping, which is a well-established and industrialized technique. For untreated wood, the wood fibers cannot be attacked by the enzymes. A relatively mild pretreatment was sufficient for wood polysaccharides hydrolyzed by a culture ...

Atopy is a frequent host characteristic that is a pre-requisite for susceptibility to asthma. Sensitization and exposure to allergens as a cause of asthma is well supported by epidemiological studies, in particular those addressing occupational asthma. The immunobiology of allergic inflammation has been explored using murine models that have provided valuable insights into the basis for the inflammatory process. The identification of two CD4 T cell subsets producing different profiles of cytokines advanced the field of T cell biology. CD4 cells (Th2) producing preferentially interleukin (IL)-4 and IL-5 are important for immunoglobulin synthesis and eosinophil differentiation, survival and activation, respectively. IL-13 has additional properties such as promoting mucous cell differentiation, fibroblast and smooth muscle activation.6 Allergic inflammation is triggered in an environment which promotes CD4 Th2 differentiation, based on the influence of such factors as IL-4 itself, thymic stromal ...

Ryo, U.Y.; Kang, B.; Townley, R.G., 1976: Cromolyn therapy in patients with bronchial asthma. Effect on inhalation challenge with allergen, histamine, and methacholine
1. Inhalation (breathing): Formaldehyde is highly irritating to the upper airways. The concentration of formaldehyde that is immediately dangerous to life and health is 100 ppm. Concentrations above 50 ppm can cause severe pulmonary reactions within minutes. These include pulmonary edema, pneumonia, and bronchial irritation which can result in death. Concentrations above 5 ppm readily cause lower airway irritation characterized by cough, chest tightness and wheezing. There is some controversy regarding whether formaldehyde gas is a pulmonary sensitizer which can cause occupational asthma in a previously normal individual. Formaldehyde can produce symptoms of bronchial asthma in humans. The mechanism may be either sensitization of the individual by exposure to formaldehyde or direct irritation by formaldehyde in persons with pre-existing asthma. Upper airway irritation is the most common respiratory effect reported by workers and can occur over a wide range of concentrations, most frequently ...
Irritants and sensitizers that can induce an allergic response following contact with the skin. Quats are also known to cause occupational asthma in cleaning workers and preliminary evidence indicates they may cause adverse genetic and reproductive effects. Chemicals in this class are persistent in the environment and toxic to aquatic organisms. Like triclosan, quats are anti-microbial agents and there is concern that their widespread use in household disinfectants and cosmetics is contributing to antibiotic resistant bacteria, thus limiting treatment options for microbial infections. The Canadian Medical Association has called for a ban on antibacterial consumer products ...

An improved understanding of indoor air chemistry would significantly benefit human health. It is estimated that at least 15% of new-onset asthma cases can be attributed to workplace exposures. The 2011 American Thoracic Society report on work exacerbated asthma identified 1) better exposure assessment methods to identify and characterize the complex exposures in workplaces and 2) investigating pathophysiological mechanisms such as neurogenic inflammation and epithelial response to oxidant stress as two of the major research gaps for addressing work exacerbated asthma reduction. Unfortunately even though indoor air is identified as a significant link between occupational lung disease and its prevention/reduction, it has been poorly understood or characterized. Research in gas-phase and surface-phase chemistries, improved field and analytical sampling methods and mechanism-based toxicology may all be used to improve indoor air quality ...
The aim of this study was to evaluate the cumulative effect of traffic related pollutants on subjects which mainly included traffic police. This evaluation is important to cater to the statistic that occupational asthma is the most common form of lung disease in the world which places the population with high exposure at great risk. We qualify the effect of exposure to pollutants like carbon monoxide, particulate diesel and other gaseous pollutant which can cause interminable harm that demonstrate as migraine, hazy vision, trouble in focus and confusion. They may also be carcinogenic with higher rates of malignancy. The predominance of respiratory complications among the policemen in highly polluted areas is higher than their counterparts. A careful assessment of history and quantification of severity markers and peak expiratory flow rate helps us identify patients who may require intensive immediate care or even hospitalization. The main objective of this work is to analyze the present health ...
Stage models are becoming increasingly popular in explaining change from current behavior to more environmentally friendly alternatives. We review empirical applications of a recently introduced model, the stage model of self-regulated behavioral change (SSBC). In the SSBC, change toward pro-environmental behavior takes place in four, qualitatively different stages (predecisional, preactional, actional, and postactional) which are each influenced by constructs taken from theories previously established to describe and predict pro-environmental behavior. We performed a systematic literature search to retrieve peer-reviewed SSBC-based studies. The review includes 10 studies published between 2013 and 2018, six of which employed a cross-sectional, three an interventional and one a correlational longitudinal design. The cross-sectional and longitudinal studies generally support the model, although there are some irregularities that warrant further investigation. The interventional studies found stage

The ICLIO Policy Summit discussion by these diverse stakeholders revealed a 360-degree perspective on the current landscape for the translation of immunotherapy from bench to bedside. Top-level themes from the Summit are highlighted below:. Biomarkers. All stakeholders concur that there is a pressing need to identify biomarkers for immuno-oncology agents in order to address the issue of identifying those patients mostly likely to benefit from being treated with an I-O agent and to help mitigate cost.. Education. New agents are emerging with new mechanisms of action, and combinations and sequencing of immuno-therapy agents are on the horizon. Understanding of side effects, late effects, and long-term effects, and the nuances of immunotherapy delivery for patients in the community continues to evolve. On-going education is imperative, not just for the multidisciplinary oncology team but also for other providers who care for these patients (e.g., primary care, endocrinologists, pulmonologists, ...

- However, although overlapping in many cases, hypersensitivity pneumonitis may be distinguished from occupational asthma in that it isn't restricted to only occupational exposure, and involves type III hypersensitivity and type IV hypersensitivity rather than the type I hypersensitivity of asthma. (wikipedia.org)
- Avoiding exposure to the substance that is causing your asthma is the best treatment. (medlineplus.gov)
- If you are exposed to any of these substances at high concentrations, you may begin wheezing and experiencing other asthma symptoms immediately after exposure. (aaaai.org)
- Workers who already have asthma or some other respiratory disorder may also experience an increase in their symptoms during exposure to these irritants. (aaaai.org)
- This type of asthma generally develops only after months or years of exposure to a work-related substance. (aaaai.org)
- Another problem with misdiagnosis of OA is continued exposure to the asthma triggers causing permanent changes and damage to your lungs. (bellaonline.com)
- In this instance, preexisting asthma is aggravated by a workplace exposure. (clevelandclinicmeded.com)
- It is therefore not surprising that patients with atopic asthma or patients with a family history of atopy are at increased risk for developing OA from exposure to HMW agents. (clevelandclinicmeded.com)
- Occupational asthma can result from exposure to a substance you're sensitive to - causing an allergic or immunological response - or to an irritating toxic substance. (drugs.com)
- If it's not correctly diagnosed and you are not protected or able to avoid exposure, occupational asthma can cause permanent lung damage, disability or death. (drugs.com)
- Start as soon as you're exposed to an asthma-inducing substance at work or only after a period of regular exposure to the substance. (drugs.com)
- The intensity of your exposure increases your risk of developing occupational asthma. (drugs.com)
- Occupational asthma refers to new onset asthma or the recurrence of previously quiescent asthma directly caused by exposure to an agent at workplace. (wikipedia.org)
- Unlike those with sensitizer-induced occupational asthma, subjects with irritant-induced occupational asthma do not develop work-related asthma symptoms after re-exposure to low concentrations of the irritant that initiated the symptoms. (wikipedia.org)
- Symptoms may develop over many years as in sensitizer induced asthma or may occur after a single exposure to a high-concentration agent as in case of RADS. (wikipedia.org)
- Most such cases of asthma occur as a result of exposure to common agents such as flour, grain, wood dust, laboratory animals and chemicals such as solder fumes, glues, latex, glutaraldehyde and isocyanates. (personneltoday.com)
- Once a person has been sensitized to one of these materials, even exposure to extremely low quantities will exacerbate the asthma. (cmaj.ca)
- The less common form of occupational asthma, accounting for about 7% of cases, is irritant-induced occupational asthma, which occurs after accidental exposure to very high inhaled concentrations of a workplace irritant. (cmaj.ca)
- Irritant-induced occupational asthma should be suspected if the symptoms first began within 24 hours after accidental exposure to a high inhaled concentration of a workplace irritant, whereas sensitizer-induced occupational asthma should be suspected if the symptoms begin during a period when the patient is working, are worse at work or in the evenings after work, and diminish during weekends or holidays.
