Disease relevance of Esophageal pH Monitoring

• Omeprazole test and 24-hour esophageal pH monitoring in diagnosing GERD [1].
• We looked for the presence of GER and reflux injury in a series of 20 patients with lower esophageal ring and dysphagia, using a 24-hour esophageal pH monitoring and upper endoscopy with biopsy [2].
• Ambulatory esophageal pH recording in gastroesophageal reflux: relevance to the development of esophagitis [3].
• Induction of thiopental anesthesia without tracheal intubation in a patient with hiatal hernia: use of esophageal pH monitoring [4].
• METHODS: Patients with Barrett's esophagus of 2-6 cm in length were treated with omeprazole (40 mg b.i.d.). They underwent 24-h esophageal pH monitoring 5 cm above the upper margin of the lower esophageal sphincter determined by a water-perfused catheter [5].

High impact information on Esophageal pH Monitoring

• The effect of 120 mL (4 oz) of scotch whiskey (40% alcohol) on nocturnal gastroesophageal reflux was studied by ambulatory esophageal pH monitoring [6].
• They underwent esophageal pH monitoring and manometry, upper gastrointestinal endoscopy, pulmonary function tests, and methacholine and capsaicin challenges [7].
• CONCLUSIONS: Esophageal pH monitoring with Bravo capsule is a safe, reliable, and tolerable method in patients with GERD [8].
• All patients had esophageal manometric evaluation, and 24-h esophageal pH monitoring was performed to determine the extent of acid and bile (bilirubin) reflux [9].
• METHODS: LESP, 24-h ambulatory esophageal pH monitoring, and serum progesterone levels were determined in 19 healthy women known to have normal menstrual cycles [10].

Biological context of Esophageal pH Monitoring

• Chest radiograph, methacholine inhalation challenge, 24-h esophageal pH monitoring, bronchoscopy, and spirometry with bronchodilator each had a sensitivity and negative predictive value of 100% [11].
• In each subject, esophageal pH monitoring was performed, with the subject in the supine position, preprandially (1 h) and 3-h postprandially after oral administration of a placebo in the morning and oral administration of nifedipine (10 mg) in the afternoon on the same day [12].

Anatomical context of Esophageal pH Monitoring

• Dual-probe esophageal pH monitoring, esophageal and respiratory manometrics (20 subjects), and basal and stimulated gastric acid secretion (4 subjects) were measured after placebo and prednisone phases [13].
• METHODS: The frequency of gastroesophageal reflux and duration of acid pH in the esophagus were determined in six thriving infants using extended esophageal pH monitoring [14].
• Eighty-six patients affected by GER symptoms and 20 healthy volunteers underwent 24-hr home esophageal pH monitoring, x-rays, and endoscopy of the upper gastrointestinal tract to investigate reliability of outpatient recording [15].

Associations of Esophageal pH Monitoring with chemical compounds

• METHODS: Thirteen of 27 patients on 60 mg lansoprazole underwent ambulatory 24 h esophageal pH monitoring while on therapy [16].
• Thirty-seven infants and children with gastroesophageal reflux were studied with prolonged esophageal pH monitoring before and during treatment with bethanechol [17].
• Effect of cisapride on esophageal pH monitoring in children with reflux-associated bronchopulmonary disease [18].
• INTERVENTIONS: The patients who were found to have GER in ambulatory esophageal pH monitoring were randomized to receive either omeprazole, 40 mg qd, or placebo for 8 weeks [19].
• Twenty-four-hour esophageal pH monitoring was conducted before and on the seventh day of the administration of baclofen [20].

Gene context of Esophageal pH Monitoring

• Fifty-nine consecutive patients with chronic unexplained excessive throat phlegm, transparent in 33 patients (TTP) and yellow in 26 patients (YTP), underwent gastrointestinal endoscopy, 24-hr dual esophageal pH monitoring, and fiberoptic DGER monitoring [21].

Analytical, diagnostic and therapeutic context of Esophageal pH Monitoring

• Evaluation of reflux episodes during simultaneous esophageal pH monitoring and gastroesophageal reflux scintigraphy in children [22].
• In such patients, an extended diagnostic work-up was performed including esophageal pH monitoring and manometry, gastric and hepatobiliary scintigraphy, and lactose tolerance test [23].
• Eighteen children with gastroesophageal reflux disease (8 with reflux esophagitis and 10 without) and 10 children with normal 24-h esophageal pH monitoring as a comparative group underwent esophagogastroduodenoscopy with biopsies [24].
