BRONCHIAL CROUP (Fibrinous Bronchitis)
This incoördination is relatively rare in small children, except in diphtheria, when it appears as a contamination into the bronchi from the larynx and trachea. It may be acute or chronic and affects all ages from infancy to puberty. The characteristics are severe dyspnea and the coughing up of fibrinous casts from the large bronchi after which there is a marked improvement. As the exudate collects again the symptoms reappear. In the chronic form there is dyspnea and expectoration of fibrinous casts.
