[Diagnostic usefulness of radioisotope study of nasal mucociliary transport in patients with recurrent respiratory infections].

Mucociliary transport system is thee most primitive and essential airway defense mechanisms. Primary ciliary dyskinesia syndrome (PCDS), an inherited recessive autosomal disease, produces an absence of mucociliary transport, therefore chronic upper and lower airways infections since birth. The study of nasal mucociliary transport by Seroalbumin-Tc99m method is very useful in the diagnosis of this syndrome. According to our experience, mucociliary stasis in a patient with chronic respiratory airways infections is a typical condition of PCDS. Normal nasal mucociliary transport velocity discards the PCDS.
