Clinico-pathological evaluation of ciliary dyskinesia: diagnostic role of electron microscopy.

From November 1995 to May 2002, the authors studied 59 children with suspected primary ciliary dyskinesia (PCD). Samples of ciliated respiratory epithelium were obtained by nasal brushing from 44 patients and by biopsy of bronchial mucosa from 15 patients. Thirty-four/Fifty-nine samples were suitable to obtain a qualitative-quantitative evaluation of ultrastructural ciliary abnormalities.
