The Boussignac continuous positive airway pressure (CPAP) device effectively treats acute pulmonary edema, but data on airway pressure with the Boussignac CPAP system are sparse. ⋯ With CPAP, pressure changes are considered to be associated with increased work of breathing. The device's pneumatic performance is adequate during normal breathing with low air flow, but during forced breathing (high air flow) it did not maintain stable airway pressure, which could increase the work of breathing and cause respiratory fatigue. Thus, the Boussignac CPAP system might be less suitable for a patient breathing at a higher frequency.

Hydatid cyst is a disease caused by a parasitic tapeworm, Echinococcus granulosus, and most commonly involves liver and lung. Ruptured pulmonary hydatid cyst can present a diagnostic challenge, and radiograph can be inconclusive. Anaphylactic reaction is a rare complication of ruptured pulmonary hydatid cyst. ⋯ Immunoglobin-G enzyme-linked immunosorbent assay for Echinococcus was positive. The patient responded well to treatment with crystalloid infusion, supplemental oxygen, and albendazole, and then underwent surgery. Anaphylactic reaction due to rupture of a hydatid cyst is rare, but hydatid disease should be suspected in patients from areas where Echinococcus is endemic.

Comparative Study
Nebulized hypertonic saline via positive expiratory pressure versus via jet nebulizer in patients with severe cystic fibrosis.
Nebulized hypertonic saline is a highly effective therapy for patients with cystic fibrosis (CF), yet 10% of patients are intolerant of hypertonic saline administered via jet nebulizer. Positive expiratory pressure (PEP) nebulizers splint open the airways and offers a more controlled rate of nebulization. ⋯ Hypertonic saline via PEP nebulizer benefits CF patients who do not tolerate hypertonic saline via jet nebulizer.

We report the first successful use of venovenous extracorporeal membrane oxygenation (ECMO) for refractory respiratory failure in an infant with DiGeorge anomaly, following thymus transplantation. A 23-month-old female with complete immune-incompetent DiGeorge anomaly 65 days after allogenic thymus transplantation was treated in our pediatric intensive care unit for acute respiratory failure secondary to bacterial sepsis. ⋯ She was successfully managed with venovenous ECMO for 4 days, with complete resolution of her respiratory symptoms. This case demonstrates the complex decision making process regarding initiation of ECMO in patients with severe immunodeficiency.
