The clinical manifestations of the gastroesophageal reflux disease (GERD) are multiple and heterogeneous, differing according to age and individual susceptibility. The relationship between respiratory manifestations and the gastroesophageal reflux (GER) in children is a contro‐ versial topic on: proving or refuting either cause or effect, with special stress on the most important symptom – coug...

BACKGROUND Persistent gastro-oesophageal reflux disease (GERD), despite proton pump inhibitor (PPI) therapy, is a common problem. Combined pH/impedance monitoring (pH/MII) enables detection of reflux episodes. Aim To identify patients with objective episodes of persistent reflux and second, to evaluate the effect of modified therapy based on the results of pH/MII. METHODS In all, 143 patients...

BACKGROUND Gastroesophageal reflux (GER) is poorly characterized in anesthetized cats, but can cause aspiration pneumonia, esophagitis, and esophageal stricture formation. OBJECTIVE To determine whether pre-anesthetic orally administered omeprazole increases gastric and esophageal pH and increases serum gastrin concentrations in anesthetized cats, and to determine the prevalence of GER using ...

This research reviews and extends the impedance-based structural health monitoring technique in order to detect and identify structural damage on various complex structures. The basic principle behind this technique is to apply high frequency structural excitations (typically higher than 30 kHz) through the surface-bonded piezoelectric transducers, and measure the impedance of structures by mon...

Multichannel intraluminal impedance (MII) is a new technique for evaluation of bolus transport. We evaluated esophageal function using bolus transport time (BTT) and contraction wave velocity (CWV) of liquid, semisolid, and solid boluses. Ten healthy subjects underwent MII swallow evaluation with various boluses of sterile water (pH 5), applesauce, three different sized marshmallows, and iced a...

Patients with refractory to proton pump inhibitors (PPIs) gastroesophageal reflux disease (GERD) symptoms are approximately 40% and represent a very common problem in clinical practice. Many of these patients do not have GERD, but suffer from functional heartburn or hypersensitive esophagus. After thorough clinical evaluation and failure of escalation of PPI dose, diagnostic investigations incl...

Apparent central apnoea (absent breathing movements) detected by monitoring movement of the thoracic wall was compared with simultaneous detection by abdominal wall movement. Eighteen infants provided one or more 24 hour recording of heart rate (electrocardiography), thoracic respiration (transthoracic impedance), and abdominal wall movement (pressure sensitive capsule distortion). Detection of...
