Impact of Coronavirus disease 2019 pandemic in children with functional abdominal pain disorders: Data from long-term follow-up.

Objective: We aimed to compare symptom frequency and severity in children with functional abdominal pain disorders (FAPDs) and to evaluate anxiety, quality of life (QoL) and global health during Coronavirus disease 2019 (COVID-19) related quarantine and after 17 months.

Methods: Children diagnosed with FAPDs between October 2019 and February 2020 at 5 different centers were enrolled and prospectively interviewed during the COVID-19 quarantine and 17 months later when schools, hospital services, and routine activities had re-opened to the public. The patients were asked to complete the Rome IV questionnaire, the Pediatric Quality of Life Inventory 4.

A significant increase in anthropometric indices during long-term follow-up of pediatric patients with celiac disease, with no endocrine disorders.

Celiac disease (CeD) is likely to be associated with growth impairment and poor weight gain. However, long-term growth patterns following diagnosis are poorly characterized. We evaluated long-term anthropometric changes in a large cohort of pediatric patients with CeD.

Gluten Immunogenic Peptides Are Not Correlated With Reported Adherence to Gluten-Free Diet in Children With Celiac Disease.

Objective: There is no gold standard to assess adherence to gluten-free diet (GFD) among patients with celiac disease (CeD). Gluten immunogenic peptides (GIPs) in urine and stool were suggested as novel markers for evaluating adherence to GFD. Our aim was to assess the presence of GIP in pediatric patients with CeD, and to compare the results with alternative methods for evaluating GFD adherence.

Long COVID-19 Liver Manifestation in Children.

Objectives: Severe acute respiratory syndrome coronavirus 2, the novel coronavirus responsible for coronavirus disease (COVID-19), has been a major cause of morbidity and mortality worldwide. Gastrointestinal and hepatic manifestations during acute disease have been reported extensively in the literature. Post-COVID-19 cholangiopathy has been increasingly reported in adults.

Diet and Pediatric Functional Gastrointestinal Disorders in Mediterranean Countries.

Background: The increased intake of FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyol) rich foods has been suggested as a possible trigger of functional gastrointestinal disorders (FGIDs). Despite the high FODMAP content, the Mediterranean diet (MD) appears to have beneficial effects on health. Our aim was to evaluate whether the prevalence of FGIDs in different Mediterranean countries may be influenced by FODMAP consumption and adherence to the MD.

Functional Gastrointestinal Disorders in Mediterranean Countries According to Rome IV Criteria.

Objectives: The aim of this study was to assess the prevalence of functional gastrointestinal disorders (FGIDs) in children of Mediterranean area using Rome IV criteria and to compare the prevalence of FGIDs using Rome IV and Rome III criteria.

Methods: This was a cross-sectional study enrolling children and adolescents living in Croatia, Greece, Israel, Italy, Macedonia, and Serbia. Subjects were examined in relation to the presence of FGIDs, using the Rome IV criteria.

Treatment adherence and behavior of pediatric liver transplant recipients during the COVID-19 pandemic.

Background: The COVID-19 pandemic has affected medical care worldwide. Thus, we aimed to assess the impact of the COVID-19 pandemic on pediatric LT recipients.

Methods: A cross-sectional study based on a structured internet or telephone survey was conducted among pediatric LT recipients.

Body composition correlates with laboratory parameters and disease severity in infants with biliary atresia.

Aim: Infants with biliary atresia (BA) generally have chronic malnutrition. However, the best anthropometric measure to assess malnutrition and its correlation with disease severity is unknown. We aimed to assess correlations of various anthropometric measurements, including air displacement plethysmography (ADP), with laboratory parameters and with the pediatric end-stage liver disease (PELD) score in infants with BA.

Overall Impact of Coronavirus Disease 2019 Outbreak in Children With Functional Abdominal Pain Disorders: Results From the First Pandemic Phase.

Objective: We aimed to assess how the first phase of coronavirus disease 2019 (COVID-19) pandemic influenced symptoms in children with functional abdominal pain disorders (FAPDs) and to characterize their quality of life (QoL), anxiety and global health.

Methods: This was a multicenter, observational, international study conducted between April and July 2020 at six different referral centers. Children diagnosed with FAPDs between October 2019 and February 2020 were enrolled and prospectively interviewed at 4 months of follow-up during the first pandemic phase (Quarantine group).

Age-Dependent Trends in the Celiac Disease: A Tertiary Center Experience.

Objectives: Celiac disease (CD) is a common intestinal autoimmune disorder with diverse presenting features. We aimed to determine age-dependent patterns in CD presentation, diagnosis and management at a large tertiary referral center.

Methods: A retrospective review of electronic medical records of pediatric patients diagnosed with CD between January 1999 and December 2018 at Schneider Children's Medical Center of Israel.

Clinical and Esophagogastroduodenoscopy Findings in Pediatric Patients With Severe Obesity Evaluated Before Bariatric Surgery.

Objectives: Severe obesity in the pediatric population has lifelong consequences. Bariatric surgery has been suggested for selected adolescents with severe obesity after careful evaluation. The indications for preoperative esophagogastroduodenoscopy (EGD) in this age group are not clear, despite its established usefulness in adults.

Adenosine kinase deficiency: Three new cases and diagnostic value of hypermethioninemia.

Adenosine kinase (ADK) deficiency is characterized by liver disease, dysmorphic features, epilepsy and developmental delay. This defect disrupts the adenosine/AMP futile cycle and interferes with the upstream methionine cycle. We report the clinical, histological and biochemical courses of three ADK children carrying two new mutations and presenting with neonatal cholestasis and neurological disorders.

Two decades of pediatric celiac disease in a tertiary referral center: What has changed?

Background: Celiac disease (CD) is common worldwide with increasing prevalence and changing presentation.

Aims: To evaluate changes in the presentation and management of CD over the last two decades.

Methods: Retrospective chart review of pediatric patients with CD between 01.

Prevalence of Functional Gastrointestinal Disorders in Children and Adolescents in the Mediterranean Region of Europe.

Background & Aims: Little is known about the prevalence of functional gastrointestinal disorders (FGIDs) in children from the Mediterranean area of Europe. We aimed to assess the prevalence of FGIDs in children and adolescents in this region.

Methods: We collected data on 13,750 children (4-18 years old) enrolled in the Mediterranean-European Area Project, a school-based health study performed in Croatia, Greece, Israel, Italy, Jordan, Lebanon, Macedonia, Serbia, and Spain.
