Congenital problems of mucociliary clearance: primary ciliary dyskinesia

Pulmonary radioaerosol mucociliary clearance in primary ciliary dyskinesia.

Primary ciliary dyskinesia (PCD) is a genetic condition affecting one in 10 000–40 000 people from birth [1]; cilia fail to beat, and the airway clearance of mucus and debris is severely impaired. If untreated, this results in progressive lung infection leading to bronchiectasis and ultimately respiratory failure. Additionally, delayed diagnosis has implications for genetic counselling, appropr...

Clinical value of measurement of pulmonary radioaerosol mucociliary clearance in the work up of primary ciliary dyskinesia

BACKGROUND We aimed to evaluate and define the general clinical applicability and impact of pulmonary radioaerosol mucociliary clearance (PRMC) on the work up of patients suspected of having primary ciliary dyskinesia (PCD). In addition, we wanted to evaluate the accuracy of the reference values used in the PRMC test. METHODS Measurement of PRMC after inhalation of (99m)Tc-albumin colloid aer...

Primary ciliary dyskinesia.

Primary ciliary dyskinesia (PCD) is a rare genetic condition that affects the ciliary function of the respiratory tract, sperm tail, cilia of the embryonic node, and fallopian tube. The condition is characterized by impaired ciliary action, leading to recurrent lower-respiratory-tract infections, bronchiectasis, rhino-sinusitis, otitis media, impaired fertility in women, and infertility in men....

Primary Ciliary Dyskinesia

Primary ciliary dyskinesia (PCD) is caused by ultrastructural ciliary defects that lead to abnormal ciliary beating and, subsequently, mucociliary dysfunction. PCD presents clinically with bronchiectasis, sinusitis, and, in up to 50% of cases, situs inversus. The ultrastructural defects of cilia are diverse but include in many cases outer and/or inner dynein arms. Recent advances have shown tha...
