Recognizing tracheobronchomalacia

Abstract: Tracheobronchomalacia is a form of expiratory central airway collapse characterized by softening of the airway wall cartilaginous structures. Symptoms often mimic asthma and chronic obstructive pulmonary disease. Pulmonary function test results may suggest a diagnosis, but findings are neither sensitive nor specific. Bronchoscopy and novel dynamic radiographic studies contribute to the diagnosis and help differentiate true malacia from other forms of expiratory central airway collapse. Treatment options include medication; noninvasive ventilatory support; interventional bronchoscopy with airway stent insertion; and open surgical procedures, such as tracheostomy, tracheal resection, and tracheoplasty.

After anunrevealing noninvasive evaluation,a high-grade B-cellintravascular lymphoma wasdiagnosed by bronchoscopywith transbronchial biopsy.Treatment with a modifiedCHOP regimen resulted in resolutionof the patient’s hypoxemiaand exercise limitation.Although intravascular pulmonarylymphoma rarely presentswith pulmonary symptoms,it should be consideredin the differential diagnosis ofpatients presenting with hypoxemiaand normal chest radiographicfindings.

Defects such as persistentthyroglossal duct and pyriform sinus fistula are associatedwith the development of AST. Ultrasonography, bariumswallow testing, CT, and fine-needle aspiration are usedfor diagnosis. Treatment includes the administration ofparenteral antibiotics, drainage, and excision.

Economic Burden Associated With Parkinson Disease

The objective of this study was to estimate the annual cost burden of Parkinson disease (PD) in the United States. Resource use and cost profiles were developed using all-payer statewide hospital discharge data from 6 states; emergency department visit, long-term–care, and national survey data; fee schedules; and published study findings. (Average direct and indirect costs per patient were calculated in 2007 US dollars.) The annual cost per patient was $21,626 (direct cost: $12,491). When applied to the US PD population (N = 500,000), the annual average cost was approximately $10.78 billion (direct costs, $6.22 billion; indirect costs, $4.56 billion). PD has substantial economic consequences for patients and their families, insurers, and society. (Drug Benefit Trends. 2009;21:179-190)
