Complications of anti-reflux surgery in gastro-esophageal reflux disease with special reference to dysphagia
All patients who underwent revision laparoscopic surgery from January 202 to July 2008 in the UCT Private Academic /Groote Scruur Hospital complex for intractable dysphagia and who did not respond to consevative treatment were reviewed. Patients with peri-oesophagel fibrosis as the dominant cause …

Exploring Gastro-oesophageal Reflux in Infants and Children
Background: Gastro-oesophageal reflux in babies, young children and teenagers is a frequent cause of symptoms, parental concern and paediatric referrals. Sequelae can include failure to thrive, haematemesis, and recurrent aspiration. Current conservative management includes reassurance, feeding …

Chiropractic management of heartburn, dyspepsia and reflux in chronically symptomatic adults
… exists regarding heartburn, dyspepsia or reflux (HDR). Objectives. This investigation aimed to build on a pilot study showing positive effects from chiropractic management of HDR. A review of the neuroanatomical and physiological rationale for chiropractic management is followed by …

Vesicoureteral Reflux and Urinary Tract Infection in Children with Congenital Hydronephrosis
We checked voiding cystourethrography (VCUG) in patients with congenital hydronephrosis (CHN) and followed up the occurrence of urinary tract infection(UTI) in these patients. And we tried to figure out the relationship between CHN and VUR and UTI. We performed a retrospective study in 122 CHN …

The design and construction of a liquid-liquid solvent extractor with reflux
… and part of the extract is recycled as reflux. A spiral-packed column for use in extractive distillation was designed and constructed. The extraction assembly consists of a single helicoid flight with a pitch of two, wound around and welded to a standard two-inch pipe, and machined to a …

Reasonability of gastro-oesophageal reflux study requests (contrast swallows and milk scans) for the detection of gastro-oesophageal reflux disease at Red Cross War Memorial Children's Hospital - a retrospective analysis
… that are often attributed to gastro-oesophageal reflux disease (GORD). The difficulty lies in distinguishing between physiological gastro-oesophageal reflux (GOR) and GORD and none of the tests available can, alone, give conclusive evidence for the latter. Clinicians are often at a loss which …

Hirschsprung´s Disease & Gastroesophageal Reflux. Aspects on Two Gastrointestinal Motility Disorders in Childhood
… Hirschsprung´s Disease (HD) and gastroesophageal reflux disease (GERD) in five different studies. HD is a congenital disease characterized by an abscence of ganglion cells in myenteric and submucous ganglia, most commonly in the distal part of the large bowel. In Paper I, we have studied the CART …

Biomechanical and morphological characterization of common iliac vein remodeling: Effects of venous reflux and hypertension
… in venous pressure due to retrograde flow (reflux) and obstruction of venous flow by intrinsic and extrinsic means are the two possible mechanisms for venous hypertension. Reflux is the prevailing theory in the etiology of venous insufficiency. The objective of this thesis is to quantify the …

Detection of Pepsin in the Sputum/Saliva for Diagnosing Atypical Manifestations of Gastroesophageal Reflux Disease
BACKGROUND/AIMS: Atypical manifestations of GERD are difficult to diagnose.We aimed to determine whether measurement of pepsin in the sputum/saliva could be useful for diagnosing atypical GERD manifestations. METHODS: Patients with clinically suspected atypical GERD symptoms provided sputum/saliva …

Factors influencing on esophageal baseline impedance levels in patients with suspected symptoms of gastroesophageal reflux disease
… significantly lower in patients with pathologic reflux, compared with the GERD-unrelated group. No significant difference in the baseline impedance levels was observed between patients with positive symptom index alone and the GERD-unrelated group. Conclusions: The time from the meal period or …

The effects of acidified pepsin on porcine vocal fold tissue: Developing a porcine model of laryngopharyngeal reflux disease
… study a common voice disorder, laryngopharyngeal reflux. <em>Ex vivo</em> pig tissue was challenged with acidified pepsin in different electrolyte environments to test the innate defense mechanisms of the vocal fold epithelium. From there, an <em>in vivo</em> pig model was designed to mimic the …

Investigation of liquid sodium alginates as mucoadhesive bandages coating the oesophageal mucosa and protecting it from gastric reflux
Gastro-oesophageal Reflux Disease (GORD), is generally caused by excess gastric reflux back to the oesophagus where damage to the mucosa results in injury. GORD is a very common disease in western countries, more than a quarter of western people are suffering from this disease and there is a trend …

Combining froth flotation and reflux classification to mitigate ARD generating potential of the Waterberg and Witbank coal ultrafines via sulfide removal
… on coal fines using the recently invented reflux classifier. The reflux classifier is claimed to be capable of separating particles down to 38 ìm in size; however, no work has been done using the reflux classifier to separate pyrite from coal. This dissertation investigates the …

Erosão dental em pacientes portadores de refluxo gastresofágico
Gastroesophagic reflux disease is a set of organic manifestations caused by gastric reflux to the esophagus. The association between Gastroesophagic reflux disease and dental erosion demonstrates the result of acid reflux. Dental erosion is defined as the irreversible loss of dental structure …
