The usefulness of the ascorbate dilution method in demonstrating intracardiac shunts and valvular incompetence is known. The ascorbate technique can also be applied to the determination of the transit time of regional vascular beds such as the coronary and the renal systems. Furthermore, the determination of central circulation times may be helpful in the diagnosis of caval obstruction. The met...
During the second hour after giving 100 ,ug of orally administered prostaglandin 15 (R) 15-methyl-E, methyl ester in the pregnant patient at term a noticeable reduction in basal gastric acid secretion took place. At this dose no excessive uterine stimulation was observed. Prostaglandin 15 (R) 15-methyl-E, methyl ester could prove of value in the preoperative preparation of the pregnant patient ...
background: non-cardiac chest pain (nccp) presents as a frequent diagnostic challenge, with patients tending to use a disproportionate level of health care resources. gastroesophageal reflux disease (gerd) is the most frequent cause of nccp. thus the typical symptoms of reflux like heartburn and regurgitation, when present as predominant symptoms are quite specific for diagnosing gerd patients ...
BACKGROUND There have been very few reports assessing the relationship between various upper gastrointestinal (GI) symptoms or evaluating each individual upper GI symptom separately. METHODS Based on the answers to Frequency Scale for the Symptoms of GERD from a large-scale population of healthy adults in Japan, a hierarchical cluster analysis was performed to categorize the typical 12 upper ...
Prolonged abnormal vomiting causes metabolic alkalosis. Many seabirds are known to feed their chicks by regurgitation. We hypothesized that metabolic alkalosis occurs in seabirds even under natural conditions during the breeding season. Adélie penguins Pygoscelis adeliae feed their chicks by regurgitating food for 50-60 d until the chicks fledge. In this study, the concentrations of Cl(-), HCO(...
OBJECTIVE Thickening of formula feedings is part of the therapeutic approach for gastroesophageal reflux (GER) in infants. However, its mechanism of action, especially regarding the occurrence of nonacid (pH >4) GER, has not yet been clearly described. The aim of this randomized, placebo-controlled crossover study was to examine the influence of formula thickened with carob (St. John's bread) b...
INTRODUCTION elderly patients appear to have a more aggressive form of gastro-oesophageal reflux disease than younger patients. Reduced pain perception with age is a possible underlying mechanism. AIMS to compare the extent of oesophageal mucosal injury, acid exposure, symptom severity and perception thresholds for acid infusion in older (aged 60 or older) and younger patients with gastro-oes...
Introduction: Ineffective esophageal motility (IEM) is an disorder (EMD) and the most prevalent abnormality routinely observed in manometry. Objectives: In this study, we investigated clinical characteristics of IEM patients effects proton pump inhibitors (PPI) surgical treatments on their conditions. Patients Methods: This cross-sectional study was conducted Isfahan 2019-2020 40 diagnosed with...
background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...
background: this study was undertaken to compare the outcome in patients with moderate to severe ischemic mitral regurgitation (imr) undergoing coronary artery bypass grafting (cabg) with either mitral valve repair or mitral valve replacement. methods: between march 2002 and february 2005, 49 consecutive patients (mean age: 62.84±8.42 years; mean euroscore: 10.03±3.12) with coronary artery dise...
