Background: The clinical features of pediatric cyclic vomiting syndrome (CVS) often evolve over time. Many patients develop a constellation of chronic symptoms that suggest autonomic nervous system (ANS) dysfunction during adolescence. We aimed to determine the proportion of children with CVS who develop chronic rather than episodic symptoms consistent with ANS dysfunction. Methods: Retrospective chart review of children ages 0–18 years followed in an outpatient tertiary care CVS center. Patients completed standardized questionnaires at intake and follow-up visits, documenting clinical symptom pattern. Continuous variables are summarized as median [interquartile range (IQR)]. A Mann-Whitney test was used for group comparisons. Results: One hundred subjects were included. A total of 40% developed symptoms of ANS dysfunction (ANS+); 20% were confirmed by comprehensive ANS testing, 11% by orthostatic vital sign abnormalities, and 9% by clinical symptoms. The median (IQR) age at onset of chronic symptoms was 14 (10.02, 15) years. The presence of another disorder of gut-brain interaction (P = 0.018) and a greater number of comorbidities (P = 0.031) were more common in the ANS+ group. ANS+ subjects missed more school days (P= 0.047) and were seen less frequently in the emergency department (P = 0.023). Conclusions: Many children with CVS (40%) develop symptoms consistent with clinical dysautonomia in adolescence. These patients experience more comorbid conditions and a greater impact on school attendance, possibly representing a worsened quality of life as their disease course transitions to daily symptoms. When symptoms of CVS change over time, therapeutic interventions may need to be adjusted and targeted accordingly.
The coronavirus disease-2019 (COVID-19) pandemic has disrupted inpatient pediatric services across the United States, creating opportunities for innovation. A recent Webinar organized by the Telehealth for Pediatric GI Care Now working group and sponsored by the North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition provided insights into how inpatient pediatric gastroenterology services were affected and how physicians adapted during the crisis. These findings suggest the use of telehealth technologies may augment family communication and facilitate multidisciplinary care in the future. We anticipate that these innovative applications of telehealth will comprise a part of a toolkit for gastroenterologists to be used during this public health emergency and beyond.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
