Evaluation of gastric histology in children and adolescents with Helicobacter pylori gastritis using the Update Sydney System.

Context: Although Helicobacter pylori infection is prevalent in our country, there are few studies evaluating the associated histological abnormalities in children.

Objective: To evaluate the histological features of the gastric mucosa in children and adolescents with Helicobacter pylori gastritis.

Methods: One hundred and thirty two gastric biopsies from 22 symptomatic patients infected with H.

Validation of a monoclonal stool antigen test for diagnosing Helicobacter pylori infection in young children.

Background And Objective: The monoclonal stool antigen test for diagnosing Helicobacter pylori infection in children has been tested in developed countries, showing sensitivity and specificity higher than 90%. However, its accuracy in young children from developing countries is not well established. The aim of the study was to determine the accuracy of the monoclonal stool antigen test for diagnosing H pylori infection in children up to 7 years old.

Furazolidone-based triple therapy for H pylori gastritis in children.

Aim: To evaluate the furazolidone-based triple therapy in children with symptomatic H pylori gastritis.

Methods: A prospective and consecutive open trial was carried out. The study included 38 patients with upper digestive symptoms sufficiently severe to warrant endoscopic investigation.

Evaluation of a protocol for postmortem examination of stillbirths and neonatal deaths with congenital anomalies.

A study was conducted on 75 perinatal deaths with congenital anomalies through clinical, radiographic, cytogenetic, and autopsy evaluation, and the diagnoses of 72 patients (96%) were determined. In 11 patients with chromosomal anomalies, the cytogenetic study was sufficient to determine the diagnosis and the reproductive risk. In these cases, the value of the autopsy results resided above all in the description of the clinical variability.

[Clinical and histological features of duodenal ulcer in children and adolescents].

Objective: To evaluate clinical and histological features of duodenal ulcer in children and adolescents.

Methods: Forty-three children with duodenal ulcer were prospectively and consecutively evaluated in a 6-year period (7.2 patients per year).

[Reflux esophagitis in children: histological and morphometric study].

Background: Gastroesophageal reflux disease is a frequent cause of morbidity in childhood, including esophagitis and recurrent respiratory symptoms; however histological and morphometric studies in esophageal biopsies of children are scarce.

Aim: To study histological and morphometric findings in children with reflux esophagitis.

Patients And Methods: We studied 26 esophageal biopsies of children (mean age: 4.

[Bilateral occipital calcification, epilepsy and coeliac disease: case report].

We report a case of a six-year-old girl with frequent diarrhea episodes associated with ferroprive anemia from 6 months of age, normal neuromotor development and partial seizures initiated in her 3rd year which was controlled with carbamazepine. CT scan in her 5th year of age demonstrated gyral calcifications in the occipital and posterior parietal regions bilaterally. MRI has shown low signal areas in the axial T2 sequences corresponding to the gyral calcifications evident on the CT.

13 C-urea breath test with infrared spectroscopy for diagnosing helicobacter pylori infection in children and adolescents.

Background And Objective: Studies support the accuracy of 13C-urea breath test for diagnosing and confirming cure of Helicobacter pylori infection in children. Three methods are used to assess 13CO2 increment in expired air: mass spectrometry, infrared spectroscopy, and laser-assisted ratio analysis. In this study, the 13C-urea breath test performed with infrared spectroscopy in children and adolescents was evaluated.
