| bronchiolitis | <chest medicine, paediatrics> This refers to inflammation of the bronchioles, usually secondary to viral infection (RSV). (13 Nov 1997) |
|---|---|
| bronchiolitis fibrosa obliterans | Obstruction of bronchioles and alveolar ducts by fibrous granulation tissue induced by mucosal ulceration; the condition may follow inhalation of irritant gases (see silo-filler's lung) or may complicate pneumonia (see BOOP); associated with obstructive findings (see unilateral hyperlucent lung, Swyer-James syndrome). Synonym: bronchiolitis obliterans. (05 Mar 2000) |
| bronchiolitis obliterans | Inflammation of the bronchioles with obstruction by fibrous granulation tissue or bronchial exudate. It may follow inhalation of irritating gases or foreign bodies and it complicates pneumonia. (12 Dec 1998) |
| bronchiolitis obliterans organizing pneumonia | A disease formerly considered a form of interstitial pneumonia. Its aetiology is obscure but it may be associated with toxic fumes, infection, and connective tissue disease. Clinical symptoms include cough, dyspnea and influenza-like symptoms with the development of the usual interstitial pneumonia in many cases. Obstructive symptoms are limited to smokers. There are patchy polypoid masses of intra-alveolar granulation tissue in small airway lumina and alveolar ducts. "organizing" refers to unresolved pneumonia (in which the alveolar exudate persists and eventually undergoes fibrosis) in which fibrous tissue forms in the alveoli. (12 Dec 1998) |
| bronchiolitis obliterans with organizing pneumonia | Bronchiolitis fibrosa obliterans complicated by pneumonia with organization. Acronym: BOOP (05 Mar 2000) |
| bronchiolitis, viral | An acute inflammatory disease of the upper respiratory tract, caused by paramyxoviruses, occurring primarily in infants and young children; the viruses most commonly implicated are parainfluenza type 3 and respiratory syncytial virus. (12 Dec 1998) |
| constrictive bronchiolitis | Obliteration of bronchioles by scarring following bronchiolitis obliterans. Compare: proliferative bronchiolitis. (05 Mar 2000) |
| proliferative bronchiolitis | Bronchiolitis with obliteration of bronchiolar lumen and alveoli by epithelial proliferation, which may follow influenza and giant-cell pneumonia. (05 Mar 2000) |
| exudative bronchiolitis | Inflammation of the bronchioles, with fibrinous exudation. (05 Mar 2000) |
| cerebral sclerosis, diffuse | Diffuse progressive degeneration of the white matter of the brain, accompanied by mental deterioration, severe motor disturbances, and early death. (12 Dec 1998) |
| goiter, diffuse toxic | Graves' disease, the most common cause of hyperthroidism, too much thyroid hormone. (12 Dec 1998) |
| chronic diffuse sclerosing osteomyelitis | A proliferative reaction of bone to a low-grade infection of the jaws; most often seen in middle-aged or older black women as extensive, often bilateral radio-opacities of the mandible and maxilla. (05 Mar 2000) |
| hyperostosis, diffuse idiopathic skeletal | A disease of elderly men characterised by large osteophytes that bridge vertebrae and ossification of ligaments and tendon insertions. (12 Dec 1998) |
| diffuse | Not definitely limited or localised, widely distributed. Origin: L. Dis = apart, fundere = to pour (18 Nov 1997) |
| diffuse abdominal calcification | <radiology> Ovarian cystadenocarcinoma (psammomatous Calcium), pseudomyxoma peritonei, pseudomucinous cystadenoma of ovary, mucocele of appendix, undifferentiated abdominal malignancy, TB peritonitis, oil granulomata, meconium peritonitis (12 Dec 1998) |
