Byssinosis

Byssinoses


Presentation

  • Bronchial obstruction was present in one case. MEF25-75 values were significantly reduced and bronchial hyperreactivity was present in both subjects.[ncbi.nlm.nih.gov]
Swelling
  • This is swelling (inflammation) of the large airways of the lungs. Call your provider if you have symptoms of byssinosis.[nlm.nih.gov]
  • Swelling of the bronchioles due to inflammation (bronchiolitis) causes narrowing of the airways. This limits the flow of air through the respiratory passages and lung function diminishes.[healthhype.com]
  • This is swelling (inflammation) of the large airways of the lungs. When to Contact a Medical Professional Call your provider if you have symptoms of byssinosis.[mountsinai.org]
Asymptomatic
  • Twenty-four (9%) had byssinosis, 178 were asymptomatic and the remaining 74 had other respiratory symptoms.[ncbi.nlm.nih.gov]
  • ..Varming H. 1994 24 Byssinosis and tuberculosis among textile mill workers in Bahar Dar, Ethiopia. ( 7941012 ) Seboxa T....Abebe Y. 1994 25 Occupational-type exposure tests and bronchoalveolar lavage analyses in two patients with byssinosis and two asymptomatic[malacards.org]
Rigor
  • URAC's accreditation program is an independent audit to verify that A.D.A.M. follows rigorous standards of quality and accountability. A.D.A.M. is among the first to achieve this important distinction for online health information and services.[umms.org]
Camping
  • Textile workers were called to a camp conducted over 3 nights and 3 days. We asked them to answer a questionnaire and tested their lung function using a Wright's ventilometer.[ncbi.nlm.nih.gov]
Cough
  • Thus, the decrease was larger in carding workers and in workers with byssinosis plus cough than in those with byssinosis or bronchitis.[ncbi.nlm.nih.gov]
  • Symptoms may include any of the following: Chest tightness Cough Wheezing Shortness of breath Symptoms are worse at the beginning of the work week and improve later in the week.[nlm.nih.gov]
  • There is breathlessness, chest tightness and cough becoming progressively worse as exposure continues.[medical-dictionary.thefreedictionary.com]
Dyspnea
  • Symptoms are chest tightness and dyspnea that worsen on the first day of the work week and subside as the week progresses. Diagnosis is based on history and pulmonary function test findings.[merck.com]
  • Even more important was the prevalence of chronic obstructive airways disease (COAD) (13.8%) and a combination of nonspecific respiratory symptoms (10.0%), characterized by chest tightness and dyspnea, but not related to any specific day of the week such[ncbi.nlm.nih.gov]
Chronic Cough
  • Unlike bronchial asthma, chronic cough and chronic bronchitis were significantly higher (p 0.01) in cotton dust exposed subjects compared with controls.[ncbi.nlm.nih.gov]
  • Byssinosis • Due to inhalation of cotton fiber dust over long periods of time • Symptoms are: – Chronic cough – Progressive dyspnea – Ending in chronic bronchitis and – Emphysema • Incidence 7 – 8% in surveys done in Mumbai, Ahmedabad and Delhi References[ihatepsm.com]
  • Later, symptoms may extend to other workdays, and finally there is severe and continuous dyspnea, chronic cough and permanent ventilatory insufficiency. Total disability and death may follow.[nejm.org]
  • Chronic cough and chronic bronchitis were relatively uncommon, which may be explained by the youth and moderate smoking habits of the workers and by the low level of atmospheric pollution.[link.springer.com]
Sputum Production
  • ‘The questionnaire was based on his byssinosis study and emphasized work-related symptoms such as chest tightness, cough, sputum production, breathlessness, day of occurrence, duration, and relationship with work.’[oxforddictionaries.com]
  • In conjunction with the above symptoms, cough with sputum production may also manifest, which can lead to a misdiagnosis of chronic obstructive pulmonary disease (COPD) or bronchitis. Evaluation There are no known diagnostic tests for byssinosis.[statpearls.com]

Suggestibility
  • It was suggested that a survey be carried out to ascertain the importance of byssinosis in the textile workers of Hong Kong and tha byssinosis should there be added to the list of notifiable occupational diseases.[ncbi.nlm.nih.gov]
Morning Headache
  • There were no significant differences in sleep related symptoms between the exposed and controls, though the 23 subjects with byssinosis tended to report more snoring (48%), early morning headache (48%), and sleep improvement over the working week (44%[ncbi.nlm.nih.gov]

Workup

Pulmonary Infiltrate
  • Fewer pulmonary infiltrates were seen in radiographs of workers with byssinosis than in those of workers with bronchitis.[ncbi.nlm.nih.gov]

Treatment

  • Treatment of byssinosis includes avoidance or reduction of exposure and use of asthma drugs. Click here for Patient Education NOTE: This is the Professional Version.[merck.com]
  • Bronchodilators are helpful for the treatment of byssinosis as it improves the symptoms. In extreme cases, steroids are also prescribed. Nebulizer treatments are also recommended in long term case scenario.[epainassist.com]
  • Tests that may be ordered include: Chest x-ray CT scan chest Lung function tests The most important treatment is to stop being exposed to the dust.[nlm.nih.gov]
  • Tests that may be ordered include: Chest x-ray CT scan chest Lung function tests Treatment The most important treatment is to stop being exposed to the dust.[umms.org]

Prognosis

  • Expectations (prognosis) Symptoms usually improve after stopping exposure to the dust. Continued exposure can lead to reduced lung function. In the U.S., worker’s compensation may be available to people with byssinosis.[coordinatedhealth.com]
  • Prognosis of Byssinosis or Brown Lung Disease or Monday Fever Most of the people suffering from this disease recover fully after completely eliminating the exposure to dust; however, people with long term and chronic exposure to cotton dust can have an[epainassist.com]
  • Prognosis Smoking, impaired lung function, and a history of respiratory allergy increase a textile worker's risk of developing byssinosis. Prolonged exposure makes patients wheeze more often and can cause chronic bronchitis.[encyclopedia.com]
  • Outlook (Prognosis) Symptoms usually improve after stopping exposure to the dust. Continued exposure can lead to reduced lung function. In the U.S., worker's compensation may be available to people with byssinosis.[healthmedicinet.com]

Etiology

  • Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.[icd10coded.com]
  • Abstract Most studies designed to determine the etiologic agent in byssinosis have relied on in vitro test for normal volunteers to assess the effects of components isolated from cotton plants, cotton factory dust, or their associated organisms.[ncbi.nlm.nih.gov]

Epidemiology

  • Abstract After a report in 1980 of the first three diagnosed locally cases and a preliminary epidemiological investigation that found little evidence of the disease, a survey was aimed at determining the prevalence of byssinosis in Hong Kong.[ncbi.nlm.nih.gov]

Pathophysiology

  • BYSSINOSIS PATHOPHYSIOLOGY The pathogenesis of farmer’s lung depends on the intensity, frequency, and duration of exposure and on host response to the causative antigen.[medifitbiologicals.com]
  • Despite modernization and introducing better working environments, byssinosis still is common in many parts of Pakistan, India, Indonesia, Ethiopia, Turkey, and Sudan. [6] , [7] Pathophysiology Not only is cotton dust implicated in the pathogenesis but[statpearls.com]
  • Available from: Byssinosis is one of the occupational diseases occurring commonly in cotton mill workers due to chronic exposure to cotton dust. [1] The pathophysiological changes in these patients are similar to chronic obstructive pulmonary disease[aeronline.org]
  • Farming is currently ranked as one of the top 3 most hazardous occupations, along with construction and mining. [4, 5] Pathophysiology The pathogenesis of farmer's lung depends on the intensity, frequency, and duration of exposure and on host response[emedicine.medscape.com]

Prevention

  • Thus, the bactericidal treating of raw cotton showed high efficiency as a potential method of byssinosis prevention.[ncbi.nlm.nih.gov]
  • Methods of prevention in the United States have reduced the number of cases. Byssinosis is still common in developing countries. Smoking increases risk of developing this disease.[nlm.nih.gov]
  • Prevention Eliminating exposure to textile dust is the surest way to prevent byssinosis. Using exhaust hoods, improving ventilation, and employing wetting procedures are very successful methods of controlling dust levels to prevent byssinosis.[encyclopedia.com]
