Randomized Controlled Trial
Self-expandable esophageal stent loaded with 125I seeds: initial experience in patients with advanced esophageal cancer.
To prospectively compare the response to treatment with a self-expandable esophageal stent loaded with iodine 125 ((125)I) seeds for intraluminal brachytherapy versus the response to treatment with a conventional self-expandable covered stent in patients with advanced esophageal cancer. ⋯ In patients with advanced esophageal cancer, treatment with an esophageal stent loaded with (125)I seeds, compared with that with a conventional covered stent, has potential benefit in that it allows a slightly longer relief of dysphagia and extended survival.

Comparative Study
Is propofol a safe alternative to pentobarbital for sedation during pediatric diagnostic CT?
To prospectively compare the incidence of adverse respiratory events, the need for airway interventions, and the recovery time after propofol sedation with similar data from a retrospective review of data obtained in patients who underwent pentobarbital sedation. ⋯ Propofol is associated with a significantly greater incidence of adverse respiratory events than is pentobarbital.

Comparative Study
Complex abdominal and pelvic abscesses: efficacy of adjunctive tissue-type plasminogen activator for drainage.
To retrospectively evaluate the effectiveness and safety of tissue-type plasminogen activator (tPA) for drainage of abdominal and pelvic abscesses refractory to simple catheter drainage. ⋯ Intracavitary tPA is safe and effective for draining complex fluid collections, with most patients avoiding surgery.
