[EX Q]: Question: Is pseudomonas aeruginosa in CF and non-CF homes found predominantly in drains?
Answer: These findings implicate drains as important potential sources of P. aeruginosa infection. They suggest that maximizing P. aeruginosa control efforts for drains would reduce exposure with minimal extra burden to CF patients and families.
[EX A]: yes

[EX Q]: Question: Is planimetry of aortic valve area using multiplane transoesophageal echocardiography a reliable method for assessing severity of aortic stenosis?
Answer: Planimetry of aortic valve area by TOE is difficult and less accurate than the continuity equation for assessing the severity of aortic stenosis.
[EX A]: no

[EX Q]: Question: Is the combination of octreotide and midodrine superior to albumin in preventing recurrence of ascites after large-volume paracentesis?
Answer: The combination of midodrine and octreotide after LVP is not superior to albumin in delaying recurrence of ascites or preventing PCD in patients with cirrhosis. Outcomes appear to be worse in patients given octreotide and midodrine. ClinicalTrials.gov number, NCT00108355.
[EX A]:
no
