A clinical and virological study of 4 cases of acute laryngotracheobronchitis is presented with a brief discussion.
Clinically acute laryngotracheobronchitis is a progressive disease with downward spread of the infection in the respiratory tract.
Rising antibody titres to influenza viruses were observed in all three patients examined, suggesting strongly an etiological association between these viruses and acute laryngotracheobronchitis.
A characteristic feature is the production of a tenacious exudate and crustig from subglottic tissues to the bronchi. This is diagnostic. Tracheotomy is often required for a relief of dyspnea, being preferable to intubation.
