Byssinosis

Byssinosis is defined as reactive airway disease, is characterized by bronchoconstriction in cotton, flax and hemp workers. The pathogen is bacterial endotoxin in cotton dust. The symptoms is to tightness of chest and dyspnea, which deteriorates the first working day of the week and decreases with the progress of the week. Diagnosis is based on medical history and findings of pulmonary function testing. Treatment is avoidance of exposure and the application of anti-asthmatic drugs.

The symptoms is to tightness of chest and dyspnea, which deteriorates the first working day of the week and decreases with the progress of the week. Diagnosis is based on medical history and findings of pulmonary function testing. Treatment is avoidance of exposure and the application of anti-asthmatic drugs. Byssinosis etiology occurs almost exclusively in workers, which come into contact with unprocessed raw cotton, especially. When handling open bales during spinning or combing of cotton. The byssinosis can after acute, but usually occur with chronic exposure. Evidence suggests that the cause of bacterial endotoxin in cotton dust. The endotoxin leads to bronchoconstriction, chronic bronchitis and gradual decline in lung function, particularly in genetically susceptible people. Earlier it was believed that continuous exposure caused to cotton dust emphysema – a theory that has now been disproved. Symptoms and signs The symptoms are tightness of chest and dyspnea, which subside with repeated exposure. The symptoms developed the first working day after a weekend or holiday and disappears towards the end of the week or decreases. With years of repeated exposure, there is apparently a tendency that the thoracic tightness persists, partly on the half of the week out and occasionally persists until the end of the week or until the end of work. In this typical time course of the Byssinosis of asthma is different. Signs of acute exposure are tachypnea and wheezing. In patients with more chronic exposure dry rales may occur. Diagnosis The diagnosis is based on medical history and on lung function tests, which show a typical obstructive lung disease and a decrease in lung ventilation, esp. In measurements at the beginning and at the end of the first layer. Also common bronchial hyperresponsiveness to methacholine is observed. Monitoring, occupational medical examinations incl. Documentation of symptoms and spirometry at textile workers can help in early detection. Therapy Treatment is avoidance or reduction of exposure and to use anti-asthmatic drugs.
