Esophageal Squamous Papilloma in the Pediatric Population.

Esophageal squamous papillomas (ESP) are rare benign tumors of the esophagus, which occur mostly in the adult population. Few cases have been reported in children and due to the low incidence, the pathogenesis of ESP is not entirely understood and the management is not standardized. It is thought that mucosal irritation from underlying inflammation, perhaps from GERD, trauma or human papilloma viruses can play a role in the formation of ESP. This report describes 4 cases of pediatric ESP from a single center and discusses the management of these lesions, including the use of antacids and the human papilloma viruses vaccine as treatment modalities. Given the limited data on ESP in the pediatric population, this report aims to describe the management of this condition in 1 center.

Constipation, renovascular hypertension, and posterior reversible encephalopathy syndrome (PRES).

UNLABELLED: Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological entity characterized by variable associations of headaches, encephalopathy, seizures, vomiting, visual disturbance, and focal neurological signs. Neuroimaging shows cerebral edema of different patterns, classically involving the parieto-occipital white matter. PRES has been associated with several conditions predominantly hypertension, eclampsia, and immunosuppressive therapy. However, constipation has not been previously described in association with the development of PRES. In this report, we describe an 11-year-old child with history of severe functional constipation who developed PRES, as a consequence of renovascular hypertension from severe fecal impaction. Both hypertension and neurologic dysfunction resolved after resolution of fecal impaction. CONCLUSION: Severe functional constipation is a previously unrecognized cause of severe acute hypertension, resulting in life-threatening neurologic dysfunction. We highlight this unrecognized complication of severe functional constipation with fecal impaction that is potentially preventable if managed appropriately.

Acute upper GI bleed in a 4-year-old boy: a case of atypical Burkitts lymphoma in a 4-year-old.

Lymphomas have been seen in the pediatric population; more frequently in patients with H. Pylori, Celiac disease, and/or patients with congenital or acquired immune deficiencies. We report a case of a 4-year old male with an acute gastric-intestinal bleed accompanied by a rare lymphoma.

The prevalence of non-alcoholic fatty liver disease and metabolic syndrome in obese children.

BACKGROUND AND AIM: In the context of present epidemic of childhood obesity, we aimed to find the prevalence of nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome (MS) in a cohort of obese children. METHODOLOGY: Retrospective chart analysis of 700 obese children was done for their anthropometric and biochemical investigations. RESULTS: Some 15.4% (9.8% girls, 22% boys) subjects had NAFLD (ALT > 40 IU/L) after excluding other identifiable causes of liver dysfunction. Age, weight, TG, fasting serum insulin and HOMA-IR levels were higher in children with NAFLD. Twenty-eight percent children had MS. Children with NAFLD had an odds ratio of 2.65 for having MS (boys 4.6, girls 1.7). The prevalence of MS increased with age 5-9 years (21%), 10-16 years (30%), 17-20 years (35%). CONCLUSION: Given high prevalence of NAFLD and MS in obese children, childhood obesity should be seriously considered as a disease and not just a cosmetic issue.

Polymorphisms in the IBD5 locus are associated with Crohn disease in pediatric Ashkenazi Jewish patients.

OBJECTIVES: To analyze the IBD5 locus in a homogenous cohort of Ashkenazi Jewish (AJ) children with Crohn disease (CD). PATIENTS AND METHODS: A total of 83 AJ children with CD and 73 AJ healthy controls were studied. Genotyping for single nucleotide polymorphisms (SNPs) including OCTN1 (SLC22A4; 1672C-->T), OCTN2 (SLC22A5; 207G-->C), IGR2096, IGR2198, and IGR2230 genes was performed using the TaqMan system. NOD2/CARD15 variants also were typed using established methods. RESULTS: All IBD5 SNPs tested were in linkage disequilibrium (D'>0.8), and showed significant association with CD in our cohort of AJ children. The IGR2096 SNP, which is not located within the same linkage disequilibrium block as the OCTN1 and 2 SNPs, showed an even stronger association with CD (P = 0.017; odds ratio = 1.7). Patients with CD who had the OCTN1 susceptibility allele were more likely to carry 1 of the 3 NOD2/CARD15 SNPs tested (P = 0.01; odds ratio = 4.8). CONCLUSIONS: We have demonstrated a significant association between the IBD5 locus and CD in a homogenous cohort of pediatric AJ patients. Due to the tight linkage disequilibrium in the region, it is not possible to identify the causative IBD5 variant. Future functional studies will ultimately reveal the causative gene variant at this locus.

Safety and symptom improvement with esomeprazole in adolescents with gastroesophageal reflux disease.

OBJECTIVES: The primary objective was to assess the safety of esomeprazole 20 or 40 mg once daily in adolescents with clinically diagnosed gastroesophageal reflux disease (GERD). A secondary aim was to assess changes in GERD symptoms after esomeprazole therapy. PATIENTS AND METHODS: In this multicenter, randomized, double-blind study, adolescents ages 12 to 17 years inclusive received esomeprazole 20 or 40 mg once daily for 8 weeks. Adverse events and changes in clinical parameters (eg, physical examination, laboratory measurements) were evaluated to assess safety. Patients or their parents or guardians scored symptom severity daily, and investigators scored overall GERD symptom severity every 2 weeks using a 4-point scale. RESULTS: In the 148 adolescents with safety data, treatment-related and non-treatment-related adverse events were reported by 75% and 78% of patients in the esomeprazole 20- and 40-mg groups, respectively. Twenty-two patients (14.9%) experienced adverse events that were considered related to treatment; the most common were headache (8%, 12/148), abdominal pain (3%, 4/148), nausea (2%, 3/148), and diarrhea (2%, 3/148). No serious adverse events or clinically important findings in other safety assessments were observed. At baseline, 68% (100/147) had heartburn, 63% (93/147) had epigastric pain, 57% (84/147) had acid regurgitation, and 15% (22/147) had vomiting symptoms. Symptom scores decreased significantly in both the esomeprazole 20-mg and 40-mg groups by the final study week (P < 0.0001). Investigators rated 63.1% (94/149) of the patients as having moderate or severe symptoms at baseline; at the final visit, this percentage decreased significantly to 9.3% (13/140; P < .0001). CONCLUSIONS: In adolescent patients with GERD, esomeprazole 20 or 40 mg daily for 8 weeks was well tolerated, and GERD-related symptoms were significantly reduced from baseline values in both groups.
