Under what circumstances is outpatient therapy possible? Using low molecular weight heparins to treat venous thromboembolism key words: Deep venous thrombosis, Pulmonary embolism, Heparin, Anticoagulant therapy

abstract: Low molecular weight heparins (LMWHs) have proved to be as safe and effective as unfractionated heparin for the treatment of venous thromboembolism. They have the advantage of not requiring frequent measurement of activated partial thromboplastin time and subsequent dosage adjustments. Patients who have deep venous thrombosis can be treated with once- or twice-daily subcutaneous doses. Hospital admission is necessary for patients with risk factors for major bleeding complications, for those with symptomatic pulmonary embolism, or when noncompliance is likely. Symptomatic proximal deep venous thrombosis and asymptomatic pulmonary embolism may be managed on an outpatient basis if there are no contraindications. Although heparin-induced thrombocytopenia occurs less frequently with LMWHs than with unfractionated heparin, the platelet count must still be monitored during therapy.

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.

Acute Suppurative Thyroiditis in a Patient With Aplastic Anemia

Acute suppurative thyroiditis (AST) is a rare inflammatorycomplication in patients with hematological malignancy.Infection spreads to the thyroid from a distant site throughthe bloodstream or the lymphatics. 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. We describea patient with aplastic anemia and bacteremic AST.[Infect Med. 2008;25:339-342]

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)
