BACKGROUND The importance of weakly acidic and weakly alkaline reflux in gastro-oesophageal reflux disease (GERD) is gaining recognition. AIM To quantify the proportions of reflux episodes that are acidic (pH <4), weakly acidic (pH 4-7) and weakly alkaline (pH >7) in adult patients with GERD, and to evaluate their correlation with symptoms. METHODS Studies were identified by systematic PubM...

A radiotelemetry system has been used to monitor gastro-oesophageal reflux over a prolonged period in 27 asymptomatic control subjects and in 15 patients with reflux symptoms. In control subjects, the frequency of reflux episodes (pH < 5) ranged from 0.1 - 0.7 per hour of recording (median 0.36) by day, and from 0 - 1.0 per hour (median 0.12) by night. The duration of reflux (pH < 5) per hour o...

BACKGROUND People with proven gastroesophageal reflux disease may also experience symptoms such as voice loss, chronic cough, globus, and sore throat. These laryngopharyngeal reflux symptoms have been reported to respond to prolonged proton pump inhibitor therapy, but the Hill approach to resolving these specific individual symptoms has not been widely reported in surgical literature. METHODS...

Myxoid valvular heart dystrophies are a frequent cause of valvular diseases. They affect approximately 3% of the population and are the most common cause of isolated mitral regurgitations that require surgical repair.1,2 These valvular diseases are a heterogeneous group of disorders and include isolated nonsyndromic valvular diseases, such as idiopathic mitral valve prolapse and the X-linked my...

Valvular regurgitation represents an important cause of cardiovascular morbidity and mortality. Echocardiography has become the primary non-invasive imaging method for the evaluation of valvular regurgitation. The echocardiographic assessment of valvular regurgitation should integrate quantification of the regurgitation, assessment of the valve anatomy, and function as well as the consequences ...

AIMS Lambl's excrescences (valvular strands) have been associated with an increased embolic risk. In previous studies, valvular strands have mostly been detected by transoesophageal echo (TEE). The current high-resolution echo systems allow better detection of valvular strands often even by transthoracic echocardiography (TTE). We attempted to determine the incidence of valvular strands during ...

IS GASTROESOPHAGEAL REFLUX DISEASE INFLUENCED BY DUODENOGASTRIC REFLUX ? (Abstract): BACKGROUND: It is well known that the gastroesophageal reflux is a frequent disease in medical practice. A lot of factors are involved in its pathogenesis. The aim of our study was to find out if the duodenogastric reflux is one of these factors. We also looked for the pathological conditions associated with du...

We studied eight patients with gastro-oesophageal reflux disease to compare the frequency and mechanism of reflux in the upright and supine positions. Simultaneous oesophageal manometry and pH studies were performed on two separate days in each subject in the fasting and postprandial periods. The frequency of reflux tended to be higher in the upright position. The most prevalent mechanism of re...

G ASTROESOPHAGEAL reflux disease (GORD) is the most common oesophageal disease. Besides the typical presentation of heartburn and acid regurgitation, GORD can cause atypical symptoms. An estimated 20–60% of patients with GORD have head and neck symptoms without heartburn 1 and at least 10% of patients who attend a general ear, nose and throat clinic will have symptoms or signs related to reflux...
