Objective: Scientific findings regarding the prevalence of celiac disease (CD) in pediatric patients with type 1 diabetes (T1D) in the Arab world are scarce. We aimed to determine the prevalence of biopsy-proven celiac disease (BPCD) among pediatric patients with T1D from Jordan. We also assessed the possible predictors for developing CD in this cohort of patients and we compared T1D patients who developed BPCD with those who had positive CD serology but negative histology and/or fluctuating CD serology. Methods: Celiac serology and duodenal biopsy results from 2012 to 2017 were collected from patients with T1D. The outcome of positive celiac serology and the risk factors for CD in T1D patients were investigated. Results: A total of 538 children of which 278 boys (51.7%) were included in the study. The prevalence of positive serology and the diagnosis of BPCD in this cohort of T1D patients were 16.6 and 9.1% respectively. Eighty percent of those with BPCD were asymptomatic and 47% were diagnosed with CD at onset of T1D. Spontaneous normalization of celiac serology occurred in 23.6% of those with positive serology. Conclusion: CD is prevalent in T1D pediatric patients from Jordan (9.1%). It is often asymptomatic and the majority of cases were diagnosed at onset or within 5 years of T1D diagnosis. Spontaneous normalization of CD serology occurred in some patients with T1D. Hence, a watchful follow-up is recommended in such patients.

Background: Helicobacter pylori is spreading worldwide with a high prevalence rate in the developing countries. Our primary goal was to measure the histology-based prevalence of Helicobacter pylori infection in children and to quantify its impact on the gastric inflammation and anemia. Our secondary goal was to study possible predictors for the presence of Helicobacter pylori in this cohort. Methods: A retrospective chart review was performed for children who underwent Esophago-gastro-duodenoscopy at Jordan university hospital in Jordan from 2008 to 2016. Data collected included epidemiological data, indication for endoscopy, endoscopic findings, and laboratory data. The gastric biopsies were re-examined by a pathologist to check for the presence of Helicobacter pylori, the presence of gastritis, and to grade gastritis according to the updated Sydney criteria. Results: A total of 98 children (53 girls– 54%) underwent Esophago-gastro-duodenoscopy. The average age was 11.7 years ± 4.7 years. Of them, 53 patients (29 boys– 55%) had Helicobacter pylori identified in the gastric biopsy. The histology-based prevalence rate of Helicobacter pylori was 54%. The most common indication for endoscopy was abdominal pain (53%) followed by vomiting (18%). Nodular gastric mucosa was present in 43% of the Helicobacter pylori-positive group, and in only 11% of the Helicobacter pylori-negative group (P-value < 0.0.5). Moderate to severe chronic gastritis was seen in 59% of the biopsies of Helicobacter pylori-positive group, compared to 31% in the Helicobacter pylori-negative group (p value < 0.05). Presence of anemia was not different between the two groups (p value > 0.05). Presence of endoscopic nodularity, active gastritis by histology, and moderate to severe gastritis by histology were positive predicators for the presence of Helicobacter pylori. (p value < 0.05). Conclusion: Helicobacter pylori infection in this study cohort of Jordanian children is common, with a histology-based prevalence rate of 54%. Nodularity of the stomach is the most common positive endoscopic feature, and its presence predicts the presence of Helicobacter pylori. Moderate to severe active gastritis is associated with Helicobacter pylori. The presence of Helicobacter pylori does not affect anemia status in this cohort of Jordanian children.

Introduction: The objective of this work is to assess the performance of our staged diagnostic pathway in the evaluation of suspected appendicitis cases in children. The pathway consisted of clinical assessment by the emergency physician, performing initial ultrasound (US), consultation, and clinical reevaluation by the surgery team followed by a repeat focused US scan in inconclusive cases. Computed tomography (CT) was limited to cases where the repeat US remained inconclusive and the clinical reassessment indicated persistent concerns for appendicitis. Method: Retrospective review of the electronic medical records of 206 consecutive children who presented to our emergency department with acute abdominal pain and underwent US examination for suspected appendicitis. The imaging findings, management plan, and surgical outcome (in those who underwent surgery) were reviewed. The diagnostic performance of the initial US, repeat US, and the full imaging protocol were evaluated including the negative appendectomy rate (NAR) and the number of CT scans performed. Results: Of the 206 cases, 73 (35.4%) had appendicitis. Computed tomography was performed in 9 (4.3%) of 206 cases. The US/CT ratio was 23:1. Our approach showed a diagnostic accuracy of 95.6% (197/206), sensitivity of 97.3% (73/75), specificity of 93.7% (124/133), positive predictive value of 89.0% (73/82), and negative predictive value of 98.7% (82/95). The NAR was 2.7% (2/72). The accuracy of the protocol is higher than that of the initial US alone (61.2%; 126/206) and that of the repeat US (84.2%; 16/19). Conclusion: The strategy of repeating limited focused US followed by CT scan in cases that remain inconclusive has good diagnostic accuracy and reasonable NAR and decreases the number of CT scans.

Secondary neonatal iron overload occurs with intrauterine and post-natal blood transfusions. Treatment with intravenous Deferoxamine was reported only in four cases in the literature. Herein we report a case of a patient born at 36 weeks of gestation, who had rhesus hemolytic disease. He developed secondary iron overload, causing liver injury, after a total of six blood transfusions: four intrauterine and 2 post-natal transfusion therapies. Intravenous Deferoxamine treatment was started at the age of 45 days due to a ferritin level of 40,000 mg/L, progressive rise of liver enzymes, and worsening cholestasis. Treatment resulted in marked reduction in ferritin level (down to 829 mg/L at the age of 6 months), significant improvement in the liver enzymes, and resolution of cholestasis.
