Use of 24 hours esophageal pHmetry for detection of gastroesophageal reflux in infants : what is the ideal score and the optimal threshold? A receive…
1997
BACKGROUND: The search for the ideal score and best cut-off value to interpret the data from 24-hour continuous pH-monitoring interests both gastroenterologists with adult patients and paediatric gastroenterologists. AIMS: To evaluate 24-hour continuous pH monitoring as a discriminatory test in the diagnosis of gastro-oesophageal reflux disease in a paediatric population, using various pH-metry scores and cut-off values. PATIENTS: One hundred and one patients presenting gastro-oesophageal reflux disease (endoscopic diagnosis of oesophagitis or coincidence between apnoea and reflux episodes observed during pH-metry), median age 10 months, were studied, together with a control group of 84 sub…
MIL-53(Al) under reflux in water: Formation of γ-AlO(OH) shell and H2BDC molecules intercalated into the pores
2014
Abstract It is shown that treatment of MIL-53(Al) (Al(OH)BDC·H2O, BDC = 1,4-benzene dicarboxylate) under reflux in water results in a progressive transformation of the solid into a new well crystallized phase. After reflux for 10 h or more the new phase is obtained in a pure form and its XRD pattern was indexed in a monoclinic system with the following cell parameters: a = 19.47 A, b = 8.98 A, c = 6.60 A, β = 107.7°. Characterization of the obtained solid by TGA, FT-IR, NMR, TEM and XRD has revealed that its composition is [0.8Al(OH)BDC·0.2H2BDC] + 0.2γ-AlO(OH). Formation of this material indicates that under reflux in water a partial hydrolysis of the MOF network occurs producing H2BDC mol…
Angiotensin II, type 2 receptor in the development of vesico-ureteric reflux
2001
Objective To investigate if mutation of the angiotensin II (Ang II) receptors AT2 is involved in primary vesico-ureteric reflux (VUR) in humans. Patients and methods Genetic polymorphisms in the AT1 and AT2 receptors was evaluated in 23 patients having the most common congenital urological abnormality, namely primary congenital VUR. The occurrence of the A1166C transition in the AT1 receptor gene and the A-1332G transition in the AT2 receptor gene were evaluated and compared with the incidence in normal controls with no urological abnormalities. Result The distribution of the AT1 receptor genotypes was no different between patients with VUR and healthy controls. Furthermore, 10 of 23 (44%) …
Oral health status among Iranian veterans exposed to sulfur mustard: A case-control study
2014
Background Sulfur mustard (SM) is a chemical warfare agent that has been repeatedly used since World War I. SM has chronic and deleterious effects on different body organs such as lungs, skin and eyes. Objectives To determine dental and oral health status of chemical victims of SM who were exposed to SM during the Iraqi-Iran war. Material and Methods In this case-control study, 100 male subjects exposed to SM were chosen as cases, and 100 non-exposed volunteers were chosen as controls. These groups were selected randomly according to their referral number, and were matched regarding age. Collection of information was performed using Oral Health Assessment Form designed by the World Health O…

Relationship between Helicobacter pylori infection and GERD
2018
Gastroesophageal reflux disease (GERD) is due to the chronic exposure of the esophageal mucosa to acid secretion from the stomach. Helicobacter pylori (H.p.) infection, is a risk factor for the development of peptic ulcer, atrophic gastritis and gastric cancer, and causes various effects on gastric function. The relationship between GERD and H.pylori infection is still subject of debate.Background and aim: In literature no clear causal relationship has been established between GERD and H. pylori infection, although some papers support the onset of esophagitis in patients in whom the infection has been cured. Aim of this work is to review the most recent literature data about the relationshi…
Helicobacter pyloriinfection and nonmalignant diseases
2017
A substantial decrease in Helicobacter pylori-associated peptic ulcer disease has been observed during the last decades. Drug-related ulcers as well as idiopathic ulcers are becoming predominant and are more refractory to treatment; however, H. pylori infection still plays an important role in ulcer bleeding and recurrence after therapy. The effect of H. pylori eradication upon functional dyspepsia symptoms has been reviewed in this article and generally confirms the results of previous meta-analyses. Additional evidence suggests a lack of impact upon the quality of life, in spite of improvement in symptoms. The association of H. pylori with gastroesophageal reflux disease and Barrett's eso…
Spanish multicentre study on morbidity and pathogenicity of tracheal bronchus in children.
2019
Tracheal bronchus (TRB) has been generally considered an anatomical variant of the tracheobronchial tree without a precise pathological effect. Its prevalence is estimated to be between 0.2% to 3% of all children undergoing bronchoscopy and scientific information has been limited to case reports or small case series. Our working hypothesis was that TRB could trigger by itself recurrent or persistent respiratory symptoms. The objective of this retrospective and multicentre study of children with a diagnosis of TRB, coming from the main paediatric pulmonology units of Spain, was to determine the anatomical and clinical characteristics, including comorbidities, of TRB in childhood and their im…
Recurrent respiratory infections caused by a double aortic arch: The diagnostic role of spirometry
2013
AbstractA young woman with a clinical history characterized by recurrent respiratory infections, occurring since early infancy, was referred to our hospital. When the patient was a young girl, she underwent sweat chloride test, serum analysis of immunoglobulins, and evaluation of blood lymphocyte subsets; all these diagnostic tests were normal, as well as chest X ray aside from pneumonia episodes. Skin prick tests were positive for several different allergens, and a diagnosis of allergic rhinitis was made. At the age of 11 years, she started to complain of gastroesophageal reflux disease (GERD) symptoms, and a gastroscopy detected a hiatal hernia with esophagitis. Despite pharmacologic trea…
