This paper describes multiple intraluminal impedance (MII) in 50 children with typical and atypical gastroesophageal reflux (GER) symptoms and discusses the possible clinical significance of objective numeric data provided by MII computed analysis. Patients underwent 24-hr pH/MII monitoring. Reflux parameters were analyzed with relation to age and reported symptoms. Nonacidic MII events occurred as frequently as acidic ones. A Pathologic Bolus Exposure Index associated with a normal pH Reflux Index was detected in 26% of our series. Significant correlations were found regarding acid and bolus clearing times and their ratio. We conclude that the low rate of symptom occurrence in the pediatric population represents a limit on MII evaluation. Our study confirmed that nonacid GER is at least as frequent as acid GER. As MII provides interesting objective data that could be used in clinical practice, we suggest further research to define normal ranges in the pediatric population.
AS remain frequent complications of esophageal surgery, especially in specific subgroups of patients. SI at 1 month after surgery could already predict the severity of the stricture and the need for subsequent endoscopic esophageal dilatations.
Objective: To report on our experience in the prenatal treatment of severe congenital diaphragmatic hernia (CDH) by fetoscopic endoluminal tracheal occlusion (FETO). Methods: Between 2012 and 2014, FETO was performed at our center in 21 cases of CDH considered to be severe based on sonographic measurement of observed/expected lung-to-head ratio (O/E LHR) and side of the defect. We reported pre- and postoperative ultrasound findings, procedure-related complications, pregnancy outcome and survival at 1-3 years of age. Results: The median gestational age (GA) at balloon insertion was 28.1 weeks (range 26.0-31.1) and the median GA at delivery 34.7 weeks (range 31.6-39.0); delivery before 32 and 34 weeks occurred in 2 (9.5%) and 7 (33.3%) cases, respectively. Postnatal survival at 1-3 years of age in the 17 cases with isolated unilateral CDH was 47.1%. The percentage difference between pre-balloon removal O/E LHR and pre-FETO O/E LHR was significantly higher in survivors compared to neonates who died (40.8 vs. 21.2%, respectively; p < 0.05). Conclusions: In this study, FETO was associated with an infant survival of 47% in cases with isolated unilateral severe CDH. The post-FETO increase in O/E LHR was higher in fetuses that survived compared to those who died.
Background: Extracorporeal membrane oxygenation (ECMO) is a complex life-saving support for acute cardio-respiratory failure, unresponsive to medical treatment. Emergency events on ECMO are rare but require immediate and proficient management. Multidisciplinary ECMO team members need to acquire and maintain over time cognitive, technical and behavioral skills, to safely face life-threatening clinical scenarios.Methods: A multistep educational program was delivered in a 4-year period to 32 ECMO team members, based on guidelines from the Extracorporeal Life Support Organization. A first traditional module was provided through didactic lectures, hands-on water drills, and laboratory animal training. The second phase consisted of a multi-edition high-fidelity simulation-based training on a modified neonatal mannequin (SimNewB®). In each session, participants were called to face, in small groups, ten critical scenarios, followed by debriefing time. Trainees underwent a pre-test for baseline competency assessment. Once completed the full training program, a post-test was administered. Pre- and post-test scores were compared. Trainees rated the educational program through survey questionnaires.Results: 28 trainees (87.5%) completed the full educational program. ECMO staff skills improved from a median pre-test score of 7.5/18 (IQR = 6–11) to 14/18 (IQR = 14–16) at post-test (P < 0.001, Wilcoxon rank test). All trainees highly rated the educational program and its impact on their practice. They reported high-fidelity simulations to be beneficial to novice learners as it increased self-confidence in ECMO-emergencies (according to 100% of surveyed), theoretical knowledge (61.5%) and team-work/communicative skills (58%).Conclusions: The multistep ECMO team training increased staff' knowledge, technical skills, teamwork, and self-confidence, allowing the successful development of a neonatal respiratory ECMO program. Conventional training was perceived as relevant in the early phase of the program development, while the active learning emerged to be more beneficial to master ECMO knowledge, specific skills, and team performance.
Carbon dioxide insufflation does not impair cardiovascular function, if intraabdominal pressure is maintained lower than 10 mmHg nor does it interfere with gas exchanges. Pneumoperitoneum slightly reduces ventilatory function, mainly in respiratory patients with various degrees of underlying bronchopulmonary impairments, but this effect is easily correctable. Thus, laparoscopic fundoplication is feasible and safe in both respiratory and gastroenterological patients, although surgery is easier and faster if periesophagitis is less evident.
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.
