Does mechanisms of acid reflux and how refluxed Acid extend proximally in patients with non-erosive reflux disease?
TLESRs are the sole motor events underlying acid reflux episodes in patients with NERD. Acid extends proximally more readily in patients with NERD than in HS and those with mild RE.
We conclude that, in patients with advanced non-small-cell lung cancer, significant change in the pulmonary clearance of 99mTc-DTPA aerosol could not be demonstrated after radiation therapy. In such patients, clearance of the aerosol does not predict the development of radiation pneumonitis.
