To analyze the causes of failure in conventional treatment to refractory gastroesophageal reflux diseases (GERD) patients, 16 refractory GERD patients (group R) and 16 cases of GERD primarily diagnosed (group P) were studied. Endoscopy, pathologic examination and 14C urea breath test were conducted in every patient. 24 h ambulatory pH and bilirubin monitoring were performed with Digitrapper MK III and Synetics Bilitec 2000. It was found that esophagitis in group R was more severe than in group P. The rate of Helicobacter pylori infection in group R was significantly lower than in group P. Fraction time pH below 4.00 was not longer while the bile reflux represented by fraction time abs above 0.14 was greater for patients in the group R as compared with those in the group P. The mixed refluxes and pure bile refluxes between the two groups had significant difference. The reflux episodes in the group R mainly occurred during nights. These results indicated that severe esophagitis, especially Barrett's esophagus with complications makes it difficult to control GERD. Severe duodenogastroesophageal refluxes (DGER) are often accompanied by refractory GERD. Mixed refluxes aggravate the esophageal injuries. Pure bile refluxes and nocturnal refluxes may cause failure of administration of proton pump inhibitors (PPI) in the morning. Helicobacter pylori infection and acid refluxes may not be the direct cause of refractoriness. Individual refractory GERD patient without abnormal results on pH or bile reflux recently should be diagnosed again.

Gastroesophageal reflux (GER) and cow's milk allergy (CMA) are common disorders in infants. In recent years, more and more research has investigated the relationship between these two diseases. Some studies reported that about half of the cases of GER in infants younger than 1 year may be an association with CMA. Therefore, overall understanding the role of CMA on the pathogenesis of GER has a great importance on improving clinical level of diagnosis and therapy. This review article tried to elaborate advances in research on the relationship between CMA and GER in infants, including epidemiology, pathogenesis, clinical manifestations, diagnosis and treatment.

Dental erosion is characterized by progressively destroyed teeth, which has no relation to bacteria but to chemicals. Some internal factors, such as gastroesophageal reflux induced by bulimia, anorexia, gastrointestinal diseases, or drugs, and external factors, such as diet, drugs, and occupational acid exposure, are considered promotive factors for this disease. This article presents a patient suffering from severe dental erosion in the whole dentition, especially in the maxillary teeth, due to gastroesophageal reflux induced by glucocorticoid therapy for optic neuritis. This article discusses the mechanism between optic neuritis glucocorticoid therapy and dental erosion.

Chronic cough is one of the most common reasons for referral to a respiratory physician. Although fatal complications are rare, it may cause considerable distress in the patient's daily life. Western and local data shows that in patients with a normal chest radiograph, the most common causes are postnasal drip syndrome, postinfectious cough, gastro-oesophageal reflux disease and cough variant asthma. Less common causes are the use of angiotensin-converting enzyme inhibitors, smoker's cough and nonasthmatic eosinophilic bronchitis. A detailed history-taking and physical examination will provide a diagnosis in most patients, even at the primary care level. Some cases may need further investigations or specialist referral for diagnosis.

Adenoid hypertrophy is a disease that mostly occurs among children of 3-5 years old. It is caused by repeated inflammation and infection of nasopharynx and its adjoin parts, or the adenoid itself, which will finally leads to pathological hyperplasia of adenoid. With so much information we have acquired about this disease, its specific mechanism remains unknown. In recent years, some researches have indicated that adenoid hypertrophy may have something to do with extra-gastroesophageal reflux, in which pepsin plays a very important role, and pepsin will do a series of pathological damages to the upper airway as it reaches the upper respiratory tract. Based on relative domestic and foreign literature, this paper attempts to make a review about the relationship between gastroesophageal reflux and adenoid hypertrophy.

The relationship between Helicobacter pylori (H. pylori) infection and gastro-esophageal reflux disease (GERD) is complex. Since some studies have suggested that H. pylori eradication may result in an increased incidence of GERD in duodenal ulcer patients, there have been debates about the protective function of H. pylori infection on GERD. H. pylori-associated antral gastritis can induce increased gastric acid output via increasing gastrin secretion. Changes in gastric acid secretion depend on the distribution (e.g. antral, corpus or pangastritis) or severity of gastritis, not on H. pylori infection itself. Patients with H. pylori infection are at risk of developing gastric mucosal atrophy, and a cohort study suggested that long-term proton pump inhibitor therapy for GERD may accelerate this process. Therefore, it has been recommended that H. pylori should be treated in GERD patients in whom a long-term antisecretory therapy is planned. The previous hypothesis that 'H. pylori infection protects from the development of GERD' is thought to be an erroneous concept recently.

The manifestations of pediatric gastroesohageal reflux (GER) are varied and complex. Extra-oesophageal symptoms, including GER-related respiratory diseases, ear, nose and throat diseases, oral diseases and neuropsychiatric symptoms, are thought to be major manifestations of pediatric GER, but the causal relationship between GER and these extra-oesophageal symptoms is still unclear. Therefore, we describe the progress of research on the relationship between GER and asthma, chronic cough, laryngitis, pharyngitis, laryngeal papilloma, sinusitis, otitis media, dental erosion, apparent life-threatening event, and the crying baby syndrome in this review. It provides new strategies for the diagnosis and treatment of GER-related diseases in children.

Esophageal atresia without tracheoesophageal fistula accounts for 7-11% of all types of esophageal atresia and is very difficult to treat. In our hospital from 1990 to 2005, we operated upon 40 patients with esophageal atresia, and 6 had pure atresia. The preoperative characteristics, operative findings and post operative course of the six patients with pure atresia were analysed. Immediate gastrostomy was performed in all 6 patients. One patient had simultaneous cervical esophagostomy. Esophageal reconstruction procedures were transhiatal gastric pull up in 3 patients, esophagocologastrostomy utilizing left colon in 1, and transthoracic esophagoseophagostomy with esophageal bougination in 2. Postoperative complications were pneumonia, anastomosis leakage, and gastroesophageal reflux symptom. Conservative management was effective in all patients. A larger series of cases would be required to demonstrate the most effective treatment for this particular anomalous condition.

OBJECTIVETo study the relationship between obstructive sleep apnea and nocturnal gastroesophageal reflux (GER).

METHODSSeventy-six patients with obstructive sleep apnea hypopnea syndrome (OSAHS) underwent polysomnography (PSG) and nocturnal distal esophageal pH monitoring, to assess the prevalence of GER in OSAHS patients. Among these patients, thirty-two OSAHS patients with GER disease had been operated on. Surgical treatment included uvulopalatopharyngoplasty (UPPP), inferior turbinate reduction, nasal septoplasty et al. After 6 months of surgical treatment, the PSG and pH probe testing were rechecked. The pre and post operative apnea-hypopnea index (AHI), micro-arousal index (MAI), lowest artery oxygen saturation (LSaO2), acidified index of distal esophagus (pHI) and percentage of acid contact time of esophagus were compared. The correlation analysis was also employed.

RESULTSThe AHI of 76 OSAHS patients was (38.6 +/- 29.5)/h (average +/- s), GER was present in 48 patients (63.2 %). The pre and post operative AHI, MAI, LSaO2, pHI and percentage of ACT in 32 OSAHS patients associated with GER were (51.2 +/- 23.1)/h and (17.3 +/- 10.3)/h, (38.3 +/- 21.4 )/h and (14.5 +/- 10.0)/h, 0.698 +/- 0.107 and 0.858 +/- 0.076, (12.5 +/- 6.6)/h and (6.3 +/- 4.2)/h, (10.3 +/- 5.2)% and (4.5 +/- 2.9)%. The differences were statistically significant by matching t test (t were 10.95, 7.82, 15.97, 6.12, 7.62 respectively, P < 0.001). There were positive relationships between the reductions of AHI, MAI and the reductions of pHI (r were 0.775, 0.764, P < 0.001). The improved levels of AHI and MAI were correlated with the reduction of the percentage of ACT (r were 0.607, 0.730, P < 0.001).

CONCLUSIONSGER is prevalent in OSAHS patients. Surgical treatment of OSAHS has significant reduction in AHI, MAI as well as marked improvement in the GER, which suggests that nocturnal gastroesophageal reflux is correlated with the disorder of sleep respiration and the sleep disturbances.
