Kartagener's syndrome--a reappraisal.

Congenital lack of dynein arms in cilia has recently been associated with Kartagener's syndrome. Ultrastructural findings from six patients with chronic stagnant secretion in the respiratory tract are briefly reported. Only one of the patients had the complete syndrome. The term Immotile-cilia syndrome has been coined, and it is suggested that Kartagener's syndrome should be included in this entity.
