Topical Pharyngeal Anesthesia in Sedated Pediatric Patients Undergoing Esophagogastroduodenoscopy.

OBJECTIVES: Pediatric patients undergoing esophagogastroduodenoscopy (EGD) commonly receive procedural sedation for comfort and to facilitate the procedure. EGD with procedural sedation carries the risk of several airway incidents and/or adverse events (AIAE). Topical pharyngeal anesthetics (TPAs) can blunt the airway reflexes and decrease the incidence of laryngospasm but has not been well studied with EGD under procedural sedation. We aimed to study the effect of adding a TPA to propofol-based sedation on the rate of AIAE. METHODS: This is a single-center, retrospective, observational cohort study. We compare AIAE rates (coughing, gagging, apnea, airway obstruction, and laryngospasm) in children who received TPA as part of their propofol-based procedural sedation for EGD with those who did not receive TPA. RESULTS: In 2021, 73 patients received TPA as part of the procedural sedation for EGD and 123 did not. The overall rate of AIAE was high with 75 (38%) patients experiencing 1 or more AIAE. Patients who received benzocaine spray experienced more AIAE than the control group [adjusted odds ratio (aOR) = 1.16; 95% confidence interval (CI): 1.01-1.34; P = 0.037]. Coughing, gagging, apnea with desaturation rates, and laryngospasm were similar in both groups (coughing aOR = 1.01; 95% CI: 0.91-1.13; P = 0.814; gagging aOR = 1.01; 95% CI: 0.91-1.13; P = 0.814; apnea aOR = 0.99; 95% CI: 0.95-1.04; P = 0.688; laryngospasm OR = 1.01; 95% CI: 0.95-1.07; P = 0.71). The rate of airway obstruction requiring jaw thrust was higher in the benzocaine group but did not reach statistical significance (aOR = 1.11; 95% CI: 0.97-1.26; P = 0.133). CONCLUSION: The use of topical pharyngeal benzocaine in children undergoing EGD with propofol-based sedation is associated with a higher overall AIAE rate. Most of the AIAE were mild incidents and only 7 patients experienced true adverse events.

Helicobacter pylori infection in a 3-week-old.

Helicobacter pylori infection is a well recognised childhood condition. A 3-week-old infant presented with clinical symptoms and endoscopic and histological findings consistent with H. pylori infection. He is the youngest infant with this infection to be reported in the literature.

Helicobacter pylori and infantile hypertrophic pyloric stenosis: is there a possible relationship?

BACKGROUND: Recently, it has been suggested that Helicobacter pylori might be a cause of some cases of infantile hypertrophic pyloric stenosis (IHPS) in infancy on the basis of its epidemiologic and clinical features. We performed this study to evaluate the possible relationship between IHPS and H. pylori. DESIGN: In consecutive infants with IHPS, we performed upper gastrointestinal endoscopy with biopsy before pyloromyotomy. The endoscopic appearance of the pylorus was noted to validate endoscopic features of IHPS. RESULTS: Sixteen infants, 15 male, 14 white, mean age 42 days, range 21 to 104 days, were studied. The index case had chronic active gastritis on biopsy with organisms suspicious for H. pylori. Four others had chronic active gastritis, six more had focal or mild chronic gastritis, five were normal, and none had H. pylori on histology or immune histochemical staining in selected cases. All patients had negative rapid urease test. Most common endoscopic findings of IHPS were thickened prominent asymmetric pyloric folds and pin-hole pylorus that could not be intubated by the pediatric endoscope. CONCLUSION: H. pylori was not specifically identified in our patients with IHPS. The presence of H. pylori-like organisms in the gastric mucosa in our index case and finding of chronic active gastritis in several others may indicate the possibility of an acquired infectious etiology for IHPS.

Epidemiologic and clinical characteristics of children with newly diagnosed inflammatory bowel disease in Wisconsin: a statewide population-based study.

OBJECTIVE: To define epidemiologic and clinical characteristics of newly diagnosed pediatric inflammatory bowel disease (IBD) in a large population-based model. STUDY DESIGN: All pediatric gastroenterologists providing care for Wisconsin children voluntarily identified all new cases of IBD during a 2-year period. Demographic and clinical data were sent to a central registry prospectively for analysis. RESULTS: The incidence of IBD in Wisconsin children was 7.05 per 100,000, whereas the incidence for Crohn's disease was 4.56, more than twice the rate of ulcerative colitis (2.14). An equal IBD incidence occurred among all ethnic groups, and children from sparsely and densely populated counties were equally affected. The majority (89%) of new IBD diagnoses were nonfamilial. CONCLUSIONS: This study provides novel, prospective, and comprehensive information on pediatric IBD incidence within the United States. The surprisingly high incidence of pediatric IBD, the predominance of Crohn's disease over ulcerative colitis, the low frequency of patients with a family history, the equal distribution of IBD among all racial and ethnic groups, and the lack of a modulatory effect of urbanization on IBD incidence collectively suggest that the clinical spectrum of IBD is still evolving and point to environmental factors contributing to the pathogenesis.
