PNEUMONOCONIOSIS DUE TO FLUE DUST

Pneumoconiosis due to graphite dust.

Lassar Dunner (1945a) recorded the clinical and radiological findings in five men who had been exposed to " pure graphite " dust. They had been exposed for 17, 18, 20, 20, and 34 years respectively, and no other dusts were known to have been implicated. Three of the men had cough, sputum, and dyspnoea; the other two had no complaints. Radiographs showed reticulation with nodulation, and the que...

Occupational asthma due to tea dust.

Three patients are described who had developed asthma after working as tea packers. In two cases the diagnosis was confirmed by serial monitoring of peak expiratory flow rates, bronchial responsiveness to histamine, and specific inhalation challenges in the laboratory. The third patient experienced isolated changes in bronchial responsiveness to histamine after periods of exposure at work and a...

First Reported Case of Reactive Airway Dysfunction Syndrome in a Laborer Due to Porcelain Tile Dust

Reactive airway dysfunction syndrome (RADS) is a type of non-immunologically mediated asthma-like disease. It usually occurs after a massive exposure to an irritating substance in the atmosphere in the form of smoke, fumes, gases, and vapor. Unlike bronchial asthma, there is no latency to the symptoms seen in RADS. A number of agents are known to cause RADS, but tile dust, as an etiological age...

Pneumonoconiosis with Special Reference to Silicosis, Anthracosis and Tuberculosis

Occupational asthma due to unheated polyvinylchloride resin dust.

Polyvinylchloride (PVC) resins are widely used in industry. Asthma due to the thermal degradation products of PVC are well documented. In this first case of occupational asthma due to unheated PVC resin dust the patient was exposed to PVC resin dust during the mixing of chemicals used for making plastic seals for bottle caps.
