A D-Dimer for Patients with High Pre-Test Probability of PE?
We know that the d-dimer can be a helpful test for patients who have a low pre-test probability of pulmonary embolism. But can the test be pushed into use for higher risk patients? Will it still have useful negative predictive value or will we risk missing too many PEs?
Can a Nitro Slurry Fix a Food Bolus Impaction?
Esophageal food impaction (EFI) occurs at an estimated rate of 13 episodes per 100,000 people annually. Medical management is typically attempted before resorting to endoscopy to reduce procedural risks and resource use. Glucagon remains the most widely used medication. Other treatments include carbonated beverages, benzodiazepines, and, more recently, nitroglycerin. Despite glucagon being the most commonly used agent, its supporting data are limited to small studies or case reports. One older study showing over 60% efficacy lacked a comparator group and had multiple confounders. Another study suggested only minimal benefit and significant adverse effects—up to 50% vomiting—highlighting the need for better treatment options.
