Answer to yesterday’s quiz; Which one of the following statements about actinomycosis is true? A. The causative organisms do not pass through tissue planes. B. It is caused by an aerobic organism. C. The causative organisms produce granules that are red. D. It may cause sinus formation if it is untreated. The answer is D. Aspiration of gastric contents tends to involve the dependent portions of the lung and can cause pulmonary infiltrates with effusions. Anaerobic infection due to aspiration of oropharyngeal contents is often a consideration. One infection that can account for a complex pleuropulmonary process with chestwall pain is actinomycosis. Actinomyces tend to produce granules that are bright yellow and localized in tissue, and the organisms can pass through tissue planes; when actinomycosis goes untreated, it can cause sinus formation and drainage at the skin surface. nej.md/1hgrIon
