Gastric Emptying in Infants with Gastroesophageal Reflux: Ultrasound Evaluation before and after Cisapride Administration
1992
The present study aimed to evaluate gastric emptying in children with gastroesophageal reflux (GER) by means of real-time ultrasonography, on the basis of measurements of the cross-sectional area of the gastric antrum. Twelve children with GER were studied (seven males, five females; age range, 3-13 months) and compared with 12 normal control children (six males, six females; age range, 3-13 months). The diagnosis of GER was confirmed by 24-h esophageal pH-monitoring. The GER patients had a significantly greater antral area than the controls at 90, 105, and 120 min after eating a standard meal (cow's milk formula, 300 ml/m2 body surface area); in addition, final gastric emptying time was si…
Domperidone plus Magnesium Hydroxide and Aluminum Hydroxide: A Valid Therapy in Children with Gastroesophageal Reflux: A Double-Blind Randomized Stud…
1994
To evaluate the efficacy of different drug combinations in treating severe gastroesophageal reflux (GER), we studied 80 children with GER. The patients were randomly divided into four groups: group A was treated with domperidone plus magnesium hydroxide and aluminum hydroxide, group B with domperidone plus alginate, group C with domperidone alone, and group D received placebo. At the time of diagnosis and 8 weeks after treatment the patients were clinically evaluated and underwent 24-h continuous esophageal pH monitoring. After treatment a complete regression of symptoms was observed in 16 of 20 patients in group A, in 8 of 20 in group B (A versus B, p < 0.018), in 9 of 20 in group C (A ver…
Using multidimensional scaling in model choice for congenital oesophageal atresia: similarity analysis of human autopsy organ weights with those from…
2020
Swine models had been popular in paediatric oesophageal surgery in the past. Although being largely replaced by rodent models, swine experienced a revival with the establishment of minipig models. However, none of them has ever been investigated for similarity to humans. We conducted a pilot study to determine whether three-week old Pietrain piglets and three-month old Aachen Minipigs are suitable for experimental paediatric oesophageal atresia surgery. We tested the operation's feasibility, performed a necropsy, weighed organs, measured organ length and calculated relative weights and lengths, and measured laboratory parameters. We used multidimensional scaling to assess the similarity of…
Gastroesophageal reflux in patients treated for congenital diaphragmatic hernia: short- and long-term evaluation with multichannel intraluminal imped…
2013
The incidence of GER, related symptoms and complications in patients treated for congenital diaphragmatic hernia (CDH) are poorly defined. The aim was to evaluate incidence and development of GER in children treated for CDH in a short- and long-term follow-up period, identifying potential risk factors of morbidity. Thirty-six patients were evaluated with pH-MII at a median age of 6 months (T1) and re-evaluated with pH-MII and endoscopy at a median age of 5 years (T2). The incidence of reflux was 83 % in T1 and 61 % in T2; the incidence of symptoms was 62 % in T1 and 38 % in T2. In both groups the reflux was mainly non-acidic. Patch, intrathoracic stomach and esophageal dysmotility were risk…
Evaluation of esophageal motility and reflux in children treated for congenital diaphragmatic hernia with the use of combined multichannel intralumin…
2011
Abstract Background Gastroesophageal reflux (GER) is frequently observed in children treated for congenital diaphragmatic hernia (CDH) at birth, as well as esophageal dysmotility, that has been hypothesized to be caused by innervatory anomalies. The aim of this study is to evaluate GER and dysmotility in young patients with CDH using pH-multichannel intraluminal impedance. Methods Thirty children (17 boys and 13 girls) who underwent repair for CDH between 2002 and 2007 with a median age of 5.2 years (range, 3-10 years) were included in the study. All patients were operated on with a subcostal laparotomy incision and had a left-sided diaphragmatic defect. The defect repair required an artifi…
Supra-esophageal manifestations of gastroesophageal reflux, a different diagnostic approach and an indication for laparoscopic Nissen fundoplication:…
2004
24-hour oesophageal pH monitoring with a dual pH probe is considered to be the most sensitive test for diagnosing GORD-related otolaryngological manifestations. In this study we evaluate an initial diagnostic approach with digital videofluorography associated to the water siphon test and primary "ex juvantibus" therapy with proton pump inhibitors for patients with supra-oesophageal symptoms of GORD. The results of Nissen fundoplication surgical treatment are also assessed in some of these patients. Two hundred and thirty patients with suspected GORD-related supra-oesophageal symptoms were referred for videofluorography and the water siphon test. When hiatal hernia and/or reflux were found, …
Immunohistochemical/histochemical double staining method in the study of the columnar metaplasia of the oesophagus
2014
Intestinal metaplasia in Barrett’s oesophagus (BO) represents an important risk factor for oesophageal adenocarcinoma. Instead, few and controversial data are reported about the progression risk of columnar-lined oesophagus without intestinal metaplasia (CLO), posing an issue about its clinical management. The aim was to evaluate if some immunophenotypic changes were present in CLO independently of the presence of the goblet cells. We studied a series of oesophageal biopsies from patients with endoscopic finding of columnar metaplasia, by performing some immunohistochemical stainings (CK7, p53, AuroraA) combined with histochemistry (Alcian-blue and Alcian/PAS), with the aim of simultaneousl…
Ramucirumab and its use in gastric cancer treatment
2014
Abstract: The inhibition of the mechanisms of tumor neo-angiogenesis represents a milestone that in the last 10 years has seen the advent of numerous molecules to target action against the vascular endothelial growth factor (VEGF). More recently, new molecules have been developed that inhibit tumor spread by the blockade of specific VEGF receptors (VEGFRs), thereby preventing the binding of a ligand to its receptor and the cascade of proliferative events downstream. Ramucirumab is a fully humanized IgG1 monoclonal antibody that performs its action by blocking the isoform 2 of the VEGF receptor (VEGFR-2). Numerous preclinical and clinical studies have demonstrated its activity in several sol…
Effects of pneumatic dilation and myotomy on esophageal function and morphology in patients with achalasia.
2005
Only two treatment modalities–pneumatic dilation and Heller myotomy–promise long-term relief from dysphagia and regurgitation in patients with achalasia. The objective of this study was to determine whether both options differ in their effects on esophageal function, morphology, and improvement in symptoms. Eighty-nine patients diagnosed with achalasia between January 1980 and December 2002 at a single center were enrolled in this study. Sixty-four patients underwent pneumatic dilation and 25 Heller myotomy in combination with an anterior semifundoplication (Dor procedure). Clinical evaluation (Eckardt-Score), esophageal manometry, and barium swallow were performed before and within 6 mont…
An evaluation of the antireflux properties of sodium alginate by means of combined multichannel intraluminal impedance and pH-metry.
2005
Summary Background : Alginate-based preparations act as mechanical antireflux barrier, which can reduce both acid and non-acid reflux events and limit the proximal migration of oesophageal refluxate. Aim : To evaluate all the above features with a novel technique, multichannel electrical impedance and pH-metry. Methods : Ten reflux patients underwent stationary impedancemetry and pH-metry after eating a refluxogenic meal. They were studied 1 h in basal conditions and 1 h after taking 10 mL of Gaviscon Advance. In both sessions, measurements were obtained in right lateral and supine decubitus. Results : Alginate preparation was able to decrease significantly (P < 0.05) the number of acid ref…
