Swallows, Wet Versus Dry

Response of the esophageal body to wet and dry swallows in Chagas' disease.

BACKGROUND Wet swallows cause a greater esophageal contraction amplitude and duration than dry swallows. In Chagas' disease there is a reduction in amplitude of esophageal contraction but we do not know if the difference between wet and dry swallows is seen in the disease. AIM To compare the esophageal contractions after wet and dry swallows in patients with Chagas' disease. METHODS We meas...

Esophageal Contractions After Wet and Dry Swallows in Patients With Esophagitis, Chagas' Disease and Idiopathic Achalasia

BACKGROUND In normal subjects the distal esophageal response to dry swallows differs from that of wet swallows. Our aim in this investigation was to compare the esophageal contractions of the proximal and distal esophageal body to wet and dry swallows. METHODS We studied the esophageal contractions of eight patients with idiopathic achalasia, 37 patients with Chagas' disease, 28 patients with...

Are Dry Mergers Dry, Moist, or Wet?

We present a spectral analysis of a sample of red-sequence galaxies identified by van Dokkum (2005) as dry merger remnants and ongoing dry mergers. Kinematics, stellar population absorption features, and ionisation from emission lines, are derived. We find that approximately half of the sample showing strong tidal features have younger stellar populations than a control sample at a given veloci...

Inhaled antibiotics: dry or wet?

Dry powder inhalers (DPIs) delivering antibiotics for the suppressive treatment of Pseudomonas aeruginosa in cystic fibrosis patients were developed recently and are now increasingly replacing time-consuming nebuliser therapy. Noninferiority studies have shown that the efficacy of inhaled tobramycin delivered by DPI was similar to that of wet nebulisation. However, there are many differences be...
