| atypical pneumonia | <chest medicine> This refers to a type of pneumonia that does not follow the typical signs and symptoms of pneumonia. A number of different viral and bacterial agents have been identified which can cause this form of respiratory infection. Examples include Chlamydia pneumonia, psittacosis, Mycoplasma, influenza A or B, adenovirus and Legionella. Antibiotics will be necessary in all but the mildest cases. Symptoms generally improve in less than 2 weeks. (27 Sep 1997) |
|---|---|
| bacterial pneumonia | Infection of the lung with any of a large variety of bacteria, especially Streptococcus pneumoniae(pneumococcus). (05 Mar 2000) |
| bilious pneumonia | Pneumonia following aspiration of gastric contents containing bile. (05 Mar 2000) |
| bronchial pneumonia | <chest medicine> A name given to an inflammation of the lungs which usually begins in the terminal bronchioles. These become clogged with a mucopurulent exudate forming consolidated patches in adjacent lobules. The disease is frequently secondary in character, following infections of the upper respiratory tract, specific infectious fevers and debilitating diseases. In infants and debilitated persons of any age it may occur as a primary affection. Synonym: bronchial pneumonia, bronchoalveolitis, bronchopneumonitis, lobular pneumonia. (11 Jan 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) |
| gangrenous pneumonia | Gangrene of the lungs. (05 Mar 2000) |
| recurrent pneumonia in childhood | <radiology> IMMUNE PROBLEMS, immune deficiency, chronic granulomatous disease of childhood, alpha-1 antitrypsin deficiency, ASPIRATION, GE reflux, H-type TE fistula, disorder of swallowing, oesophageal obstruction, UNDERLYING LUNG DISEASE, sequestration, brochopulmonary dysplasia, cystic fibrosis, atopic asthma, bronchiolitis obliterans, sinusitis, bronchiectasis, ciliary dysmotility syndromes, pulmonary foreign body (12 Dec 1998) |
| giant cell pneumonia | A rare complication of measles, with the postmortem finding of multinucleated giant cells lining alveoli. Synonym: Hecht's pneumonia, interstitial giant cell pneumonia. (05 Mar 2000) |
| caseous pneumonia | A form of severe pulmonary tuberculosis in which tubercles are not prominent, but with a diffuse extensive cellular infiltration that undergoes caseation affecting large areas of lung. (05 Mar 2000) |
| viral pneumonia | <radiology> Common agents: RSV, parainfluenza, adenovirus, influenza (12 Dec 1998) |
| virus pneumonia of pigs | A worldwide chronic pneumonia usually involving only the anterior lobes; it seldom causes death but is responsible for much unthriftiness; it is caused by the bacterium Mycoplasma hyopneumoniae. Synonym: virus pneumonia of pigs. (05 Mar 2000) |
| central pneumonia | A form of pneumonia in which exudation is confined for a time to the central portion of a lobe or the hilar region. Synonym: core pneumonia. (05 Mar 2000) |
| chemical pneumonia | <chest medicine> Pneumonia caused by the inhalation of a toxic gas, such as phosgene or chlorine. (05 Jan 1998) |
| rheumatic pneumonia | Pneumonia rarely occurring in severe acute rheumatic fever, even when the disease was common; consolidation occurs, the lungs being of a rubbery consistency, with fibrin exudate and small haemorrhages, as well as oedema from left ventrical failure. (05 Mar 2000) |
