Lung ultrasound in the follow-up of primary ciliary dyskinesia.

Primary ciliary dyskinesia (PCD) is an airways ciliary defect, making them unable to beat normally. Hence, there is an increase in the incidence of respiratory recurrent infections leading to multiple atelectasis from different lung lobes during the first months of life repeat chest X-ray (CXR) controls with increase of radiation exposure in this younger population. We report the lung ultrasound follow-up of two newborn diagnosed with PCD. The illness in these cases was suspected during the first days of life due to worsening of respiratory distress on previous healthy newborns. Both patients cases show the ability of bedside lung ultrasound (LUS) to confirm clinical suspicion of atelectasis or pneumonia. Using LUS for the diagnosis and follow-up may help in avoiding routine CXR, thus reducing the huge amount of ionizing radiation in these patients.
