| rhinitis, atrophic | A chronic form of rhinitis marked by wasting of the mucous membrane and the glands. It is usually associated with crusting and foul-smelling discharges. (12 Dec 1998) |
|---|---|
| chronic atrophic polychondritis | A degenerative disease of cartilage producing a bizarre form of arthritis, with collapse of the ears, the cartilaginous portion of the nose, and the tracheobronchial tree; death may occur from chronic infection or suffocation because of loss of stability in the tracheobronchial tree of autosomal origin. Synonym: chronic atrophic polychondritis, generalised chondromalacia, Meyenburg's disease, Meyenburg-Altherr-Uehlinger syndrome, relapsing perichondritis, systemic chondromalacia, von Meyenburg's disease. (05 Mar 2000) |
| chronic atrophic thyroiditis | Replacement of the thyroid gland by fibrous tissue, the commonest cause of myxoedema in older persons. (05 Mar 2000) |
| chronic atrophic vulvitis | An inflammation of atrophic vulvar skin, usually with severe pruritus. (05 Mar 2000) |
| alveolar duct emphysema | Emphysema in which the primary involvement is in the alveolar ducts and respiratory bronchioles, as opposed to panacinar emphysema. (05 Mar 2000) |
| bullous emphysema | Emphysema in which the enlarged airspaces are one to several cm in diameter, often visible on chest radiographs. Thin-walled air sacs under tension compress pulmonary tissue, either single or multiple. Sometimes amenable to surgical resection with improvement in pulmonary function. (05 Mar 2000) |
| gangrenous emphysema | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| panacinar emphysema | Emphysema affecting all parts of the lobules, in part, or usually the whole, of the lungs, and usually associated with a1-antiprotease deficiency emphysema. Synonym: diffuse emphysema, generalised emphysema, panacinar emphysema. (05 Mar 2000) |
| panlobular emphysema | Emphysema affecting all parts of the lobules, in part, or usually the whole, of the lungs, and usually associated with a1-antiprotease deficiency emphysema. Synonym: diffuse emphysema, generalised emphysema, panacinar emphysema. (05 Mar 2000) |
| generalised emphysema | Emphysema affecting all parts of the lobules, in part, or usually the whole, of the lungs, and usually associated with a1-antiprotease deficiency emphysema. Synonym: diffuse emphysema, generalised emphysema, panacinar emphysema. (05 Mar 2000) |
| paraseptal emphysema | Emphysema involving the periphery of the pulmonary lobules. (05 Mar 2000) |
| mediastinal emphysema | Presence of air in the mediastinal tissues due to leakage of air from the tracheobronchial tree, usually as a result of trauma. (12 Dec 1998) |
| centri-acinar emphysema | Emphysema affecting the lobules around their central bronchioles, causally related to bronchiolitis, and seen in coal-miner's pneumoconiosis. Synonym: centri-acinar emphysema. (05 Mar 2000) |
| centrilobular emphysema | Emphysema affecting the lobules around their central bronchioles, causally related to bronchiolitis, and seen in coal-miner's pneumoconiosis. Synonym: centri-acinar emphysema. (05 Mar 2000) |
| compensating emphysema | Compensatory emphysema, increase in the air capacity of a portion of the lung when another portion is consolidated, shrunken, or unable to perform its respiratory function; the alveoli are distended, but there is no destruction of alveolar walls, and hence, no true emphysema, as this term is now defined.
