[EX Q]: Rush immunotherapy (RIT) presents an attractive alternative to standard immunotherapy. However, RIT carries a much greater risk of acute allergic reactions, including anaphylaxis.', 'We hypothesized that omalizumab, a humanized monoclonal anti-IgE antibody, would be effective in enhancing both safety and efficacy of RIT.', 'Adult patients with ragweed allergic rhinitis were enrolled in a 3-center, 4-arm, double-blind, parallel-group, placebo-controlled trial. Patients received either 9 weeks of omalizumab (0.016 mg/kg/IgE [IU/mL]/mo) or placebo, followed by 1-day rush (maximal dose 1.2-4.0 mug Amb a 1) or placebo immunotherapy, then 12 weeks of omalizumab or placebo plus immunotherapy.', 'Of the 159 patients enrolled, 123 completed all treatments. Ragweed-specific IgG levels increased >11-fold in immunotherapy patients, and free IgE levels declined >10-fold in omalizumab patients. Patients receiving omalizumab plus immunotherapy had fewer adverse events than those receiving immunotherapy alone. Post hoc analysis of groups receiving immunotherapy demonstrated that addition of omalizumab resulted in a 5-fold decrease in risk of anaphylaxis caused by RIT (odds ratio, 0.17; P = .026). On an intent-to-treat basis, patients receiving both omalizumab and immunotherapy showed a significant improvement in severity scores during the ragweed season compared with those receiving immunotherapy alone (0.69 vs 0.86; P = .044).

[EX Q]: Epinephrine is a component of all resuscitation algorithms. Vasopressin is a pulmonary vasodilator and systemic vasopressor. We investigated the effect of epinephrine vs. vasopressin on survival and hemodynamics after neonatal porcine cardiac arrest (CA).', 'A 4-min asphyxial CA was induced, after which cardiopulmonary resuscitation (CPR) was commenced. Animals were randomized to low- (LDE: 0.01 mg/kg) or high-dose epinephrine (HDE: 0.03 mg/kg), low- (LDV: 0.2 U/kg) or high-dose vasopressin (HDV: 0.4 U/kg), or control (saline). Clinical and echocardiography indexes were monitored.', 'Sixty-nine animals were randomized. Survival was greater in HDV (n = 8 (89%); P < 0.05 ANOVA) vs. control (n = 7 (43%)) and LDE (n = 5 (36%)) but not vs. HDE (n = 7 (64%)) or LDV (n = 6 (75%)). Animals resuscitated with LDE required more shocks (2.5 (interquartile range: 2-6); P < 0.05) and higher doses of energy (15 J (interquartile range: 10-20); P < 0.05). Left ventricular output was comparable between groups, but a greater increase in superior vena caval flow was seen after HDV (P < 0.001 vs. control, LDE, and HDE). Plasma troponin was greatest in the HDE group (P < 0.05 vs. control and HDV).

[EX Q]: The objective was to evaluate whether endobronchial ultrasonography (EBUS) or endoscopic ultrasonography (EUS) staging techniques of the mediastinum for lung cancer can change the treatment plan compared with the "gold standard" of surgical staging.', 'Patients were retrospectively identified from a prospectively collected database. Endoscopic staging was compared with the "gold standard" cervical mediastinoscopy (CM). In cases where mediastinoscopy was not performed, EBUS/EUS was compared with "ideal" CM, a virtual procedure, which was assumed to have 100% rates of sensitivity and specificity.', 'EBUS was performed in 324 patients (99%), EUS in 295 patients (90%), and CM in 101 patients (31%); 226 patients (69%) were assumed to have undergone a virtual ideal CM and a virtual surgical mediastinal staging; 108 positive biopsies (33.0%) with endosonography had sampling of targets that were out of the scope of CM. Distant metastatic disease was diagnosed by EBUS/EUS in 7 patients (2.1%); 22 patients (6.7%) had positive targets outside the reach of the CM or virtual CM. If the 14 patients who had positive stations 5, 6, 10, and 11 are excluded (accessible with anterior mediastinotomy or extended cervical mediastinoscopy), there were 6 patients (1.8%) in whom endosonography upstaged the patient over ideal surgical mediastinal staging. In 20 patients (6.1%), ultrasound-guided biopsy made the diagnoses, which changed the treatment plan over CM and ideal CM.
