Broken wind is a syndrome characterised by chronic bronchitis and alveolar emphysema. Clinical signs include nasal catarrh, persistent coughing, dyspnoea and poor exercise tolerance. In racehorses, lung haemorrhages may result in epistaxis. Broken wind is a disease of domestication ascribed to pollution of the stable air with fungal spores from hay and straw. Treatment and prevention are based on the provision of fresh air and, if housing is unavoidable, the adoption of a permanent regime of dust-free stable management. If an early diagnosis is made and appropriate treatment instituted, the prognosis is considered to be reasonably good. The disease exemplifies the validity of the Royal Veterinary College motto Venienti occurrite morbo (treat the disease at its first appearance).

The harmful effect of cement dust upon living organisms consists in irritating, sensitizing and pneumoconiotic properties of its components. In animal studies it has been observed that cement dust induces atrophic and hypertrophic changes in nasal and pharyngeal mucosa and chronic exfoliative bronchitis. In the lungs of experimental animals slight tissue fibrosis and some emphysema foci were found. The examination of workers exposed to cement dust has shown that disorders of the upper respiratory airways they suffer from include most often chronic rhinitis, laryngitis and pharynx catarrh. Also, it has been noticed that chronic bronchitis in the exposed workers was 1.7 times more frequent compared to those non-exposed, and that asthma was diagnosed in some of the exposed workers. Chronic bronchitis was usually characterized by the symptoms of impaired, obstructive lung ventilation. Defects in lung ventilation were strictly related to the duration of mild cases of cement pneumoconiosis diagnosed in a small percentage of workers who were exposed for at least 10 years to high dust concentrations. Long-term contact of skin with cement results in inflammatory changes or, in some cases, in chemical burns. Etiological factors of inflammatory skin changes are allergenic elements (Cr, Nr, Co) and irritating agents found in cement.
