Secondary airway malacia was defined as airway malacia secondary to esophageal atresia, VATER/VACTERL association (condition with vertebral anomalies, anal atresia, congenital heart disease, tracheoesophageal fistula or esophageal atresia, renourinary anomalies, or radial limb defects), vascular or other external compression of the airways, or specific syndromes. Treatment
Time
Minimally Invasive, usually in conjunction with Continuous Positive Airflow Pressure. Continuous Positive Airflow Pressure
A method of respiratory ventilation. Tracheotomy
Surgical procedures on the neck to open a direct airway through an incision in the trachea (the windpipe). Prosthesis
Insertion of a prosthesis to keep the bronchial tube open. Notes

In females, where plasma VLCFA measurement is not always conclusive (some female carriers will have normal VLCFA in plasma), molecular analysis is preferred, particularly in cases where the mutation in the family is known. Although the clinical phenotype is highly variable among affected males, the elevations of VLCFA are present in all males with an ABCD1 mutation.Because the characteristic elevations associated with ALD are present at birth, well before any symptoms are apparent, there have been methods developed in the interests of including it in newborn screening programs. One of the difficulties with ALD as a disease included in universal newborn screening is the difficulty in predicting the eventual phenotype that an individual will express. The accepted treatment for affected boys presenting with the cerebral childhood form of the disease is a bone marrow transplant, a procedure which carries significant risks. However, because most affected males will demonstrate adrenal insufficiency, early discovery and treatment of this symptom could potentially prevent complications and allow these patients to be monitored for other treatment in the future, depending on the progression of their disease.The Loes score is a rating of the severity of abnormalities in the brain found on MRI. It ranges from 0 to 34, based on a point system derived from the location and extent of disease and the presence of atrophy in the brain, either localized to specific points or generally throughout the brain. A Loes score of 0.5 or less is classified as normal, while a Loes score of 14 or greater is considered severe.
