Abstract
BACKGROUND The incidence of gastroesophageal reflux disease (GERD) has been shown to be elevated in individuals with epilepsy. Traditional observational studies have led to a limited understanding of the effects of GERD and BE on epilepsy due to the interference of reverse causation and potential confounders. METHODS We conducted a bidirectional two-sample Mendelian randomization (MR) analysis to determine whether GERD and BE can increase the risk of epilepsy. Genome-wide association study data on epilepsy and its subgroups were obtained from the International League Against Epilepsy consortium for primary analysis using three MR approaches and the FinnGen consortium for replication and meta-analysis. We calculated causal estimates between the two esophageal diseases and epilepsy using the inverse-variance weighted method. Sensitivity analysis was conducted to detect heterogeneity and pleiotropy. RESULTS We found a potential effect of genetically predicted GERD on the risk of epilepsy (odds ratio [OR] = 1.078; 95% confidence interval [CI], 1.014-1.146, p = .016). Specifically, GERD showed an effect on the risk of generalized epilepsy (OR = 1.163; 95% CI, 1.048-1.290, p = .004) but not focal epilepsy (OR = 1.059, 95% CI, 0.992-1.131, p = .084). Notably, BE did not show a significant causal relationship with the risks of generalized and focal epilepsy. CONCLUSIONS Under MR assumptions, our findings suggest a potential risk-increasing effect of GERD on epilepsy, especially generalized epilepsy. Considering the exploratory nature of our study, the association between GERD and epilepsy needs to be confirmed by future prospective studies.

Clinical characteristics of children with severe neurologic impairment: A scoping review. J Hosp Med 2023; 18:65-77. [PMID: 36484088 PMCID: PMC9829450 DOI: 10.1002/jhm.13019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 10/21/2022] [Accepted: 11/16/2022] [Indexed: 12/13/2022]
Abstract
OBJECTIVE The aim of this study is to extrapolate the clinical features of children with severe neurologic impairment (SNI) based on the functional characteristics and comorbidities described in published studies. METHODS Four databases were searched. We included studies that describe clinical features of a group of children with SNI (≥20 subjects <19 years of age with >1 neurologic diagnosis and severe functional limitation) using data from caregivers, medical charts, or prospective collection. Studies that were not written in English were excluded. We extracted data about functional characteristics, comorbidities, and study topics. RESULTS We included 102 studies, spanning 5 continents over 43 years, using 41 distinct terms for SNI. The terms SNI and neurologic impairment (NI) were used in 59 studies (58%). Most studies (n = 81, 79%) described ≥3 types of functional characteristics, such as technology assistance and motor impairment. Studies noted 59 comorbidities and surgeries across 10 categories. The most common comorbidities were related to feeding, nutrition, and the gastrointestinal system, which were described in 79 studies (77%). Most comorbidities (76%) were noted in <10 studies. Studies investigated seven clinical topics, with "Gastrointestinal reflux and feeding tubes" as the most common research focus (n = 57, 56%). The next most common topic, "Aspiration and respiratory issues," included 13 studies (13%). Most studies (n = 54, 53%) were retrospective cohorts or case series; there were no clinical trials. CONCLUSIONS Despite the breadth of described comorbidities, studies focused on a narrow set of clinical topics. Further research is required to understand the prevalence, clinical impact, and interaction of the multiple comorbidities that are common in children with SNI.

Esophageal pH-impedance monitoring in children: position paper on indications, methodology and interpretation by the SIGENP working group. Dig Liver Dis 2019; 51:1522-1536.

Abstract
Multichannel intraluminal impedance pH (MII-pH) monitoring currently represents the gold standard diagnostic technique for the detection of gastro-esophageal reflux (GER), since it allows to quantify and characterize all reflux events and their possible relation with symptoms. Over the last ten years, thanks to its strengths and along with the publication of several clinical studies, its worldwide use has gradually increased, particularly in infants and children. Nevertheless, factors such as the limited pediatric reference values and limited therapeutic options still weaken its current clinical impact. Through an up-to-date review of the available scientific evidence, our aim was to produce a position paper on behalf of the working group on neurogastroenterology and acid-related disorders of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) on MII-pH monitoring technique, indications and interpretation in pediatric age, in order to standardise its use and to help clinicians in the diagnostic approach to children with GER symptoms.

Abstract
UNLABELLED Patterns of childhood gastroesophageal reflux (GER) have been studied extensively; however, the mechanisms underlying its occurrence in neurologically impaired children (NIC) are poorly understood. Concurrent esophageal manometry and pH monitoring was conducted in 10 un-operated children (7 male; mean age: 59.5 months) with sequelae birth asphyxia and esophagitis. Reflux episodes were scored when esophageal pH decreased to <4 for at least 5 s. When the rate of decrease of lower esophageal sphincter (LES) pressure was >1 mmHg/s, the decrease of LES pressure was defined as LES relaxation. The time relationship of the pharyngeal manometric swallowing signal to LES relaxation onset was then evaluated in order to distinguish between LES relaxations associated with swallowing (type II or III, associated with one or more swallows, respectively) and those that occurred independently of swallowing (type I). RESULTS Esophageal manometry and pH monitoring were conducted for a mean duration of 91.5 min. Basal LES pressure averaged (+/-SD) 9.2+/-4.8 mmHg; in 4 of 10 patients (40%) the LES pressure was largely undetectable, varying between 0 and 2 mmHg. Mean LES pressure was inversely correlated with age (r=0.7, P=0.02). The total number of reflux episodes/h averaged 32.1+/-12.1 LES pressure reached 0 mmHg in 98% of reflux episodes. Type I LES relaxations were present in 3.15+/-1.1 reflux episodes/h, whereas type II LES relaxation occurred in 2.3+/-2.4 episodes/h. Acid reflux episodes appeared during absent basal LES tone periods, without phasic LES relaxations, in 74%. CONCLUSIONS Absent basal LES tone is the main mechanism of GER in a subgroup of NIC, especially in older children. Transient LES relaxation, the most common known event associated with acid reflux in neurologically normal children, seems to precede a minority of reflux events in NIC.

Abstract
BACKGROUND Although generalist physician faculty typically lack the skills needed to conduct research, few medical schools offer on-site faculty development programs that teach research skills. DESCRIPTION To address this dilemma, our medical school introduced a part-time Primary Care Research Fellowship offering full-day classes once a week over 10 months. EVALUATION We asked the 22 general internists, general pediatricians, and family physicians who participated in the program to rate their experience, and we measured their research productivity during the 3 years before and 3 years after completing the program, using a group of matched controls for comparison. Participants rated the program highly and increased their aggregate research productivity from 1 publication before completing the program to 6 publications afterward, although this increase did not reach statistical significance (p = .09). Controls exhibited substantially higher baseline productivity than fellows (10 publications vs. 1 publication, p = .03), but controls' productivity changed little between the first and second measurement periods (10 and 7 publications, respectively). CONCLUSION Our mid-career research training program enabled primary care academic faculty to gain confidence in their ability to conduct a scientific study with minimal disruption to their teaching and clinical activities.

Abstract
In neurologically impaired patients (NIP), surgical management of gastroesophageal reflux disease (GERD) has become a widespread standard. Several follow-up studies have shown a high incidence of complications and recurrent reflux. As one of the possible causes epilepsy is mentioned repeatedly in the literature. The aim of this study was to determine the effective impact of epilepsy on the postoperative outcome by comparing results of our patients suffering from epilepsy to those without this disorder. From 1984 to 1999, a total of 45 NIP underwent antireflux surgery, including 20 patients suffering from epilepsy (EP) and 25 patients without this disorder (nEP). The existence of epileptic disorders, incidence of epileptic seizures and administration of anticonvulsatory drugs as well as results of diagnostic procedures, postoperative complications and incidence and time of recurrence of pathologic GER were recorded and analysed retrospectively. Preoperatively all patients had pathologic results in 24 h pH-monitoring. Median RI was 15.75 (EP, range 5.2-28.6) and 17.55 (nEP; range 7.2-26.5). 12-months-postoperative 24 h pH-monitoring showed a median RI of 3.8 (EP; range 1.3-25.6) versus a median RI of 3.3 (nEP; range 0.7-26.3). During the long-term follow-up evaluation of 3.9 years, 17 EP suffered from persistent epileptic seizures despite medical treatment. 19 patients (42%) developed recurrent reflux. This included seven EP (35%) and 12 nEP (48%). The necessity of reoperation was higher in nEP (n = 5, 20%) than in EP (n = 1, 5%). This analysis did not show a significant correlation between recurrence of pathologic GER after fundoplication and the incidence of epileptic seizures. We consider our findings to strongly question the widespread opinion considering this correlation. We conclude, that cerebral seizures alone do not alter the operative outcome of antireflux surgery in NIP.
