BACKGROUND Primary ciliary dyskinesia (PCD) is a rare congenital disorder involving permanent ubiquitous structural and/or functional ciliary abnormalities. METHODS A single-center retrospective study included 56 cases of PCD (respiratory form) out of a cohort of 280 patients with suspected PCD. The main features of history-taking and clinical examination were analyzed, to formulate a pragmatic diagnostic procedure, easy to implement in clinical practice. RESULTS Chronic respiratory tract infectious symptoms are sensitive but non-specific for the diagnosis of PCD. Nasal brushing for phase-contrast microscopy study of ciliary morphology and activity proved to be a fast, easy, non-invasive, cost-effective and age-independent diagnostic method. In doubtful cases, depending on local availability, further tests are indicated: nasal nitric oxide level, electronic microscopy, genetic study and cell culture. CONCLUSIONS In suspected PCD, there being no gold standard method of screening and early diagnosis, nasal brushing with ciliary study is contributive, alongside numerous other complementary tests, on condition that the clinician is experienced and results are interpreted in the light of clinical examination and history-taking.

UI MeSH Term Description Entries
D007619 Kartagener Syndrome An autosomal recessive disorder characterized by a triad of DEXTROCARDIA; INFERTILITY; and SINUSITIS. The syndrome is caused by mutations of DYNEIN genes encoding motility proteins which are components of sperm tails, and CILIA in the respiratory and the reproductive tracts.

D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
