Rolleston, G. L., Maling, T. M. J., and Hodson, C. J. (1974). Archives of Disease in Childhood, 49, 531. Intrarenal reflux and the scarred kidney. The incidence and significance of intrarenal reflux (pyelotubular backflow) occurring during micturating cystourethrography has been studied in 386 examinations on patients with vesicoureteric reflux. This phenomenon has not been observed in patients...

Eighty children with bronchial asthma and ten control cases underwent radionuclide gastroesophagography for the detection of gastroesophageal reflux. Thirty nine per cent asthmatic children demonstrated esophageal reflux on scintiscanning. The ten control subjects had no reflux. The presence of reflux correlated strongly with the presence of nocturnal exacerbation of symptoms. Bronchodilator th...

Gastroesophageal reflux disease (GERD), or its variation known as laryngopharyngeal reflux (LPR), has been recognized as a potential cause of several laryngeal disorders. Patients with laryngeal cancer have lifestyle risk factors, especially tobacco and alcohol consumption, that play an etiological role in the development of their cancer but also places them at risk for reflux. The question the...

According to the 2006 Montreal globally acceptable definition and classification of gastroesophageal reflux disease (GERD), this condition develops when the reflux of gastric contents causes symptoms or complications (Vakil et al., 2006). Because reflux esophagitis is defined as occurring when reflux of gastric acid into the esophagus causes mucosal breaks, erosions and/or ulcers, this conditio...

Esophageal pH monitoring is considered the gold standard for the diagnosis of gastroesophageal reflux disease because of the normal ranges across the pediatric age range. However, this method can only detect acid reflux. Multichannel intraluminal impedance-pH (MII-pH) monitoring has recently been used for the detection of bolus reflux in infants and children. This method allows for the detectio...

Vesicoureteral reflux is a commonly encountered condition in pediatric urology. The treatment of vesicoureteral reflux is debated in all patients. Much controversy exists regarding the need to reimplant refluxing ureters at the time of bladder augmentation, particularly in those patients with neuropathic bladders. In patients with neuropathic bladders, reflux may be the result of elevated detru...

Simultaneous intraoesophageal pH and pressure monitoring were performed for 12 hours in 20 patients with abnormal acid gastrooesophageal reflux or oesophagitis and in 10 healthy volunteers to determine characteristic reflux patterns with time. Increased acid exposure was not the only factor that characterised patients with oesophagitis. Indeed an overlap existed between patients with and withou...

The influence of intermittent positive pressure ventilation on gastro-oesophageal reflux in preterm infants is not known. In many neonatal units, however, concern that ventilation may increase gastro-oesophageal reflux (and therefore aspiration) leads to avoidance of enteral feeding during ventilation. We have therefore performed a crossover study of gastrooesophageal reflux by monitoring lower...

a shortcut procedure as quick, easy-to use method for design and simulation of multicomponent batch distillation is used to predict the operating condition of recovering xylene from solvent in an existing batch distillation column in benzol refinery. the procedure can be used to investigate the effect of the operating parameters on the operation of column for three possible modes of batch disti...

BACKGROUND The role of gastropharyngeal reflux in patients with globus pharyngeus and hoarseness remains unclear. OBJECTIVE To evaluate patients with complaints of globus, hoarseness, or globus and hoarseness combined for the presence of gastropharyngeal and gastroesophageal reflux. DESIGN Prospective clinical cohort study of 3 groups of patients undergoing ambulatory 24-hour double-probe p...
