Objective: To assess the relationship between bacterial enteritis and intussusception.Study Design: The Patient Administration Systems and Biostatistics Activity database from January 2002 to December 2005 was examined for clinic visits or hospital admission to a Department of Defense medical facility for children age 0-5 years. The study included the International Statistical Classification of Diseases and Related Health Problems diagnosis-related group (DRG) codes for infections with Yersinia enterocolitica, Escherichia coli, Shigella species, Salmonella species, and Campylobacter. Identified patients were then assessed for the intussusception DRG code for 0-180 days postinfection. The total number of children enrolled in military treatment facilities in the same age group (denominator) was obtained.Results: Bacterial enteritis significantly increased the relative risk of intussusception. An increased risk was found following infection with Salmonella, E coli, Shigella, and Campylobacter. The relative risk for intussusception following any bacterial enteritis was 40.6 (95% confidence interval = 28.6-57.5; P < .0001).Conclusions: Bacterial enteritis is a significant risk factor for the subsequent development of intussusception in children.

Objectives: There is a paucity of data describing the frequency and complications of body piercing injuries (BPI) in the United States., Methods: We conducted a cross-sectional study using the National Electronic Injury Surveillance System (NEISS) to identify emergency department (ED) visits for BPI from 2011-2020 and to estimate prevalence among US individuals ≤24 years of age. Additionally, estimates for infections, requirements for hospitalization/transfer, and exploring significant associations were investigated., Results: A total of 10,912 ED visits extrapolates to a national estimate of 338,972 BPIs in the United States. A majority of BPI involved females (85%), adolescents or young adults (55%), and ears (71%). Foreign bodies comprised 72.6% of BPI. Thirteen percent of ED piercing visits were associated with infection. Of these ED visits for BPI-associated infection, 3% required hospitalization/transfer. In the context of all piercing-associated injuries, injuries to the pubic region were 16.8 times more likely to require hospitalization compared to body piercing injuries of the ear. In the context of all piercing-associated infections, navel (lower trunk), nipple (upper trunk), and oral (mouth) locations were associated with increased odds of infection when compared to BPI infections of the ear., Conclusions: BPI is a common problem in children, adolescents, and youth. Age and body piercing location significantly impact rates of BPI, infection, and hospitalization/transfer. Further study should identify the total number of annual body piercings in the United States. This could generate targeted counseling and risk reduction interventions aimed at specific groups, especially older children who appear to be at increased risk., Competing Interests: Conflict of interest disclosures (includes financial disclosures): All authors have no conflicts of interest relevant to this article to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Functional constipation (FC) comprises 30% of pediatric gastroenterology clinic visits. FC results from withholding behaviors that can be worsened by poor toileting posture. The use of a defecation posture modification device (DPMD)-a potty stool-has demonstrated benefit in adults. The aim of this study was to assess the risks and benefits of incorporating a DPMD as an adjunct to the FC treatment plan for children. Toilet-trained children aged ≥4 years meeting the Rome IV criteria for FC were enrolled and offered a DPMD at no cost and were followed for 4 months. There were no injuries or treatment-related adverse events reported by the 43 subjects who completed the study. Notably, 98% (n = 42) of respondents would recommend the DPMD to assist other children with FC. DPMD users showed a 33% reduction in fecal incontinence compared with 60% non-users. The DPMD represents a safe adjunct to incorporate into the FC management plan of children., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

INTRODUCTION: Military aviation poses unique occupational risks, including exposures to intermittent hypoxia, high gravitational force, and toxic materials, in addition to circadian disruption, cosmic radiation, and ergonomic stressors also present in commercial flight. We sought to investigate whether a military aviation officer's career is associated with adverse maternal or fetal health outcomes. METHODS: We conducted a retrospective cohort study of female aviation and nonaviation officers in the Military Health System from October 2002 to December 2019. Exposure was identified as assignment of an aviation occupation code. Maternal and fetal health outcomes were identified by International Classification of Diseases codes from medical records. Regression analysis was used to estimate adjusted relative risks (aRR). RESULTS: Included in the study were 25,929 active-duty female officers, with 46,323 recorded pregnancies and 32,853 recorded deliveries; 2131 pregnancies were diagnosed in aviation officers. Pregnant aviation officers had a decreased risk of composite adverse pregnancy outcomes [aRR 0.82 (0.73-0.92)], including gestational diabetes [aRR 0.69 (0.57-0.85)] and gestational hypertension [aRR 0.84 (0.71-0.99)]. Pregnant aviation officers had a decreased risk of depression prior to delivery [aRR 0.43 (0.35-0.53)] and hyperemesis gravidarum [aRR 0.74 (0.57-0.96)], but an increased risk of placental complications [aRR 1.15 (1.02-1.30)] and fetal growth restriction [aRR 1.36 (1.16-1.60)]. DISCUSSION: Pregnant military aviation officers have an increased risk of placental complications and fetal growth restriction in spite of a lower risk of gestational diabetes and gestational hypertension. Further research is needed to determine how flight-related occupations impact pregnancy.

Introduction: Congenital syphilis (CS) case rates have increased significantly in the United States over the past 20 years, accelerating during the COVID-19 pandemic. Increasing rates may relate to access to care but have not been evaluated in a fully-insured population, such as the Military Health System., Materials and Methods: We performed a repeated monthly cross-sectional study of CS cases and total encounters (care rates) using the queried Military Health System database. We defined CS by International Classifications of Diseases 10th Revision Clinical Modification diagnosis codes in beneficiaries  ≤ 2 years old. We evaluated pre-COVID-19 (March 2018 to February 2020), pandemic year 1 (March 2020 to February 2021), and pandemic year 2 (March 2021 to February 2022) periods. We performed change-point and trend analyses and Poisson regression to evaluate differences by sponsor rank, TRICARE region, and pandemic period. The Uniformed Services University Institutional Review Board approved the study., Results: A total of 69 unique CS cases were identified with a median monthly care rate of 0.90/100,000 eligible beneficiaries. The CS care rate showed a 5.8% average monthly percent increase throughout the study period (P < .001) and a 20.8% average monthly percent increase in year 2 (P < .05). Compared to the pre-pandemic era, CS care rates increased in pandemic years 1 and 2 (adjusted rate ratio [aRR] 2.76 [95% CI: 1.95-3.92], 5.52 [95% CI: 4.05-7.53], respectively). Congenital syphilis care rates were lower in children of senior enlisted sponsors versus junior enlisted, aRR 0.24 (95% CI: 0.17-0.33), and higher in the West and North regions versus South, aRR 2.45 (95% CI: 1.71-3.53) and aRR 2.88 (95% CI: 2.01-4.12), respectively., Conclusions: Congenital syphilis care rates were substantially lower in this insured group than national rates but increased significantly during the COVID-19 pandemic. Higher care rates were seen in children of military members of lower rank. Regional trends differed from national data. These findings suggest that, even in a fully-insured population, income and regional differences impact CS, and the COVID-19 pandemic may have exacerbated differences in care delivery., (© The Association of Military Surgeons of the United States 2024.

Objective: Celiac disease (CD) is an immune-mediated enteropathy that is associated with pneumococcal infections in adults. The objective of this study is to evaluate the association between CD and pneumococcal infections in hospitalized pediatric patients in the United States (US)., Study Design: The triennial Healthcare Cost and Utilization Project Kids' Inpatient Database was used in a retrospective analysis of children hospitalized in the US from 1997 to 2019. Billing codes were used to define patients with CD who were admitted with Streptococcus pneumoniae speciated infections or an infection commonly caused by S. pneumoniae. A multivariable logistic regression model was used to quantify increased odds of various types of infections for patients with CD., Results: Among 55,080,914 pediatric hospital admissions, 15,412 were identified with CD, and 1,722,872 were admitted with the specified infections. CD was associated with both pneumococcus speciated infections (odd ratio [OR], 2.16, 95% confidence interval [CI], 1.38-3.38) and infections commonly caused by S. pneumoniae (OR, 1.78; 95% CI, 1.61-1.96): pneumonia (OR, 1.70; 95% CI, 1.53-1.89), sinusitis (OR, 2.41, 95% CI, 1.76-3.30), and bacteremia (OR, 2.12; 95% CI, 1.56-2.88). Patients with CD had a significantly longer length of stay (p < 0.001) and a greater cost of hospitalization (p < 0.001) with pneumococcus associated infections., Conclusions: CD is associated with an increased risk of both pneumococcus speciated and pneumococcus-associated infections requiring hospitalization. CD admissions are associated with longer hospital stays and higher costs without increased risk of death. Routine pneumococcal vaccinations are strongly recommended for pediatric patients with CD., (© 2024 European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Eosinophilic esophagitis (EoE) disease activity can be caused by treatment non-adherence. Medication possession ratio (MPR) is an established metric of medication adherence. A higher MPR correlates with better outcomes in several chronic diseases, but MPR has not been investigated with respect to EoE. A retrospective cohort study was performed using an established EoE registry for the years 2005 to 2020. Treatment periods were identified, MPRs were calculated, and medical records were assessed for histologic remission (<15 eos/hpf), dysphagia, food impaction, stricture occurrence, and esophageal dilation that corresponded to each treatment period. In total, 275 treatment periods were included for analysis. The MPR in the histologic remission treatment period group was 0.91 (IQR 0.63-1) vs. 0.63 (IQR 0.31-0.95) for the non-remission treatment period group ( p < 0.001). The optimal MPR cut-point for histologic remission was 0.7 (Sen 0.66, Spec 0.62, AUC 0.63). With MPRs ≥ 0.7, there were significantly increased odds of histologic remission (odds ratio 3.05, 95% confidence interval 1.79-5.30) and significantly decreased odds of dysphagia (OR 0.27, 95% CI 0.15-0.45), food impaction (OR 0.26, 95% CI 0.11-0.55), stricture occurrence (OR 0.52 95% CI 0.29-0.92), and esophageal dilation (OR 0.29, 95% CI 0.15-0.54). Assessing MPR before repeating an esophagogastroduodenoscopy may decrease unnecessary procedures in the clinical management of eosinophilic esophagitis.

Objective: This study examined the impact of the COVID-19 pandemic on healthcare engagement for anorexia nervosa (AN) and bulimia nervosa (BN) in a large, geographically diverse population., Method: This repeated monthly, cross-sectional study queried Military Health System records of individuals aged 10-21 before and during the pandemic (February 2019-January 2022). ICD-10 codes identified encounters for AN and BN. Monthly rates of care were modeled as the number of unique individuals with an ICD-10-identified eating disorder-related encounter per month divided by the enrolled population. Poisson regression analysis evaluated rates of care stratified by eating disorder, clinical setting, and sex., Results: In a population of 1.76 million adolescents and young adults, 1629 individuals with AN or BN received care during the pre-pandemic period; 3256 received care during the pandemic. The monthly rate of care for females with AN during the pandemic increased in inpatient settings (adjusted relative risk [aRR]: 1.31 [1.16-1.49]) and outpatient settings (aRR: 1.42 [1.37-1.47]); monthly care rates in males with AN increased in the outpatient setting (aRR: 1.46 [1.28-1.67]). Females with BN had increased engagement in outpatient settings (aRR: 1.09 [1.03-1.16]); BN care for males showed no significant monthly changes during the pandemic period in either healthcare setting., Discussion: With increased rates of AN and BN disorder-related care during the pandemic, screening for eating disorder symptomatology may allow for timely diagnosis and intervention in periods of heightened stress. Pandemic-related increases in healthcare engagement may strain limited resources, emphasizing a need to expand accessibility of clinical expertise., Public Significance: This study indicates that monthly rates of healthcare engagement during the COVID-19 pandemic for AN and BN varied based on clinical setting and sex in an adolescent and young adult population. The increased number of individuals seeking eating disorder-related care, especially outpatient care, attributed to heightened stressors necessitates accessible professionals with eating disorder clinical expertise., (Published 2023.

Background: IgE to the oligosaccharide galactose-alpha-1,3-galactose (alpha-gal) is an important cause of allergic reactions to mammalian meat. The "alpha-gal syndrome" is strongly associated with a preceding history of tick bites and in the United States is most commonly reported in parts of the southeast, but there has been limited investigation into national alpha-gal sensitization patterns and the relevance of other risk factors., Objective: To systematically investigate alpha-gal IgE prevalence, regional patterns, and risk factors., Methods: Alpha-gal IgE was measured by ImmunoCAP in biobanked serum samples collected from 3000 service members who presented for intake to 1 of 10 military bases in the central/eastern United States. Alpha-gal IgE sensitization (cutoff 0.1 international units/mL) was related to home of record at enlistment., Results: Of the cohort, 2456 (81.9%) subjects were male, median age was 19 years (interquartile range: 18-22 years), and alpha-gal IgE was detected in 179 (6.0%). Home of record spanned all 50 states, with a median of 36 recruits per state (range: 3-261). The highest prevalence rates were in Arkansas (39%), Oklahoma (35%), and Missouri (29%), with several other southeastern states >10%. Granular mapping revealed sensitization patterns that closely mimicked county-level Amblyomma americanum reports and Ehrlichia chaffeensis infections. Sensitization was associated with male sex, rural residence, and White race in univariate and multivariable models., Conclusions: In this systematic survey, the prevalence of alpha-gal IgE among incoming military personnel was 6.0%. There were significant regional differences, with an overall pattern consistent with the known range of the lone star tick (A. americanum) and highest frequency in an area including Arkansas, Oklahoma, and Missouri., (Copyright © 2023 American Academy of Allergy, Asthma & Immunology.

Introduction: The USA is experiencing an opioid epidemic. Active duty service members (ADSMs) are at risk for opioid use disorder (OUD). The Coronavirus disease 2019 (COVID-19) pandemic has disrupted health care and introduced additional stressors., Methods: The Military Healthcare System Data Repository was used to evaluate changes in diagnosis of OUD, medications for OUD (MOUD), opioid overdose (OD), and opioid rescue medication. ADSMs ages 18-45 years enrolled in the Military Healthcare System between February 2019 and April 2022 were included. Joinpoint Trend Analysis Software calculated the average monthly percent change over the study period, whereas Poisson regression compared outcomes over three COVID-19 periods: Pre-lockdown (pre-COVID-19 period 0) (February 2019-February 2020), early pandemic until ADSM vaccination initiation (COVID-19 period 1 [CP1]) (March 2020-November 2020), and late pandemic post-vaccination initiation (COVID-19 period 2 [CP2]) (December 2020-April 2022)., Results: A total of 1.86 million eligible ADSMs received care over the study period. Diagnoses of OUD decreased 1.4% monthly, MOUD decreased 0.6% monthly, diagnoses of opioid OD did not change, and opioid rescue medication increased 8.5% monthly.Diagnoses of OUD decreased in both COVID-19 time periods: CP1 and CP2: Rate ratio (RR) = 0.74 (95% CI, 0.68-0.79) and RR = 0.72 (95% CI, 0.67-0.76), respectively. MOUD decreased in both CP1 and CP2: RR = 0.77 (95% CI, 0.68-0.88) and RR = 0.86 (95% CI, 0.78-0.96), respectively. Adjusted rates for diagnoses of opioid OD did not vary in either COVID-19 time period. Opioid rescue medication prescriptions increased in CP1 and CP2: RR = 1.09 (95% CI, 1.02-1.15) and RR = 6.02 (95% CI, 5.77-6.28), respectively., Conclusions: Rates of OUD and MOUD decreased, whereas rates of opioid rescue medication increased during the study period. Opioid OD rates did not significantly change in this study. Changes in the DoD policy may be affecting rates with greater effect than COVID-19 pandemic effects., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2023.

Historically, respiratory syncytial virus (RSV) infection trends have been predictable. The COVID-19 pandemic and associated precautions impacted RSV disease patterns. RSV infection trends during the first year of the COVID-19 pandemic may have predicted the 2022 surge in pediatric RSV infections. A continued emphasis on increased viral testing will allow for early recognition and preparation for future public health crises., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 Wolters Kluwer Health, Inc.

Objective: To investigate why certain at-risk individuals develop celiac disease (CD), we examined the association of proton pump inhibitors (PPI), histamine-2 receptor antagonists (H2RAs), and antibiotic prescriptions in the first 6 months of life with an early childhood diagnosis of CD., Study Design: A retrospective cohort study was performed using the Military Healthcare System database. Children with a birth record from October 1, 2001, to September 30, 2013, were identified. Outpatient prescription records were queried for antibiotic, PPI, and H2RA prescriptions in the first 6 months of life. Cox proportional hazards regression was used to calculate the hazard ratio (HR) of developing CD based on medication exposure. International Classification of Diseases, Ninth Revision, Clinical Modification codes identified children with an outpatient visit for CD., Results: There were 968 524 children who met the inclusion criteria with 1704 cases of CD in this group. The median follow-up for the cohort was approximately 4.5 years. PPIs (HR, 2.23; 95% CI, 1.76-2.83), H2RAs (HR, 1.94; 95% CI, 1.67-2.26), and antibiotics (HR, 1.14; 95% CI, 1.02-1.28) were all associated with an increased hazard of CD., Conclusions: There is an increased risk of developing CD if antibiotics, PPIs and H2RAs are prescribed in the first 6 months of life. Our study highlights modifiable factors, such as medication stewardship, that may change the childhood risk of CD., (Published by Elsevier Inc.)

Objective: To implement and to evaluate the effectiveness of the Uniformed Services Constipation Action Plan (USCAP) in our gastroenterology clinic for children with functional constipation., Study Design: This implementation science study included toilet-trained subjects aged 4 years and older who met the Rome IV criteria for functional constipation. Children were block randomized to receive either the USCAP or control. All clinic functional constipation plans recommended subjects continue pharmacotherapy for 4 months. Endpoints measured were clinical outcomes (resolution of functional constipation and achievement of a Pediatric Bristol Stool Form Scale [PBSFS] score of 3 or 4), patient-related outcomes (health-related quality of life [HRQoL] total scale score), and health confidence outcomes (Health Confidence Score [HCS])., Results: Fifty-seven treatment group subjects (44%) received a USCAP (52% male; mean age, 10.9 [4.9] years) compared with 73 controls (56%; 48% male; mean age,10.9 [5.3] years). A PBSFS score of 3 or 4 was achieved by 77% of the treatment group compared with 59% of controls (P = .03). Subjects from the treatment group were more likely than the controls to endorse adherence to the 4-month course of pharmacotherapy (P < .001). Subjects who received a USCAP had greater improvements in HRQoL total scale score by the end of the project (P = .04)., Conclusions: The USCAP is a simple, inexpensive tool that has the potential to improve global outcomes for functional constipation in children and should be recommended as standard clinical practice., (Published by Elsevier Inc.)

The COVID-19 pandemic has drastically impacted administration of healthcare including well-child visits and routine vaccinations. The purpose of this study was to determine the impact of COVID-19 pandemic disruption on childhood health maintenance: well-child visits and scheduled vaccinations. We queried the TRICARE Management Activity's Military Health System (MHS) database for outpatient well-child visits and vaccinations for all children 0 to 23 months of age eligible for TRICARE healthcare. The median rate of well-child visits, during the COVID-19 period (March 2020-July 2021), was significantly declined for all demographic groups: all ages, parental military ranks, sex, and regions as compared to the pre-COVID-19 period (February 2019-February 2020). Similar to rates of well-child visits, the rate of vaccinations declined during the COVID-19 period as compared to the pre-COVID-19 period for all demographic groups, except children 12-23 months. Rates of well-child visits for military dependent children under 2 years of age were decreased during the 16 month COVID-19 period, with large increases seen in the first 2 months of the pandemic; the consequences of missed well-child visits and vaccination are unknown.

Objective: To examine the association between antibiotic and acid suppressant prescriptions in the first 2 years of life and subsequent treatment for childhood psychiatric disorders., Study Design: This was a retrospective cohort study of children born between October 2001 and September 2012 in the Military Health System enrolled in TRICARE past age 2 years and within 35 days of birth, with an initial hospital stay <7 days, and without psychotropic agents dispensed during the first 2 years of life. Exposure was defined as a filled prescription for an antibiotic or acid suppressant before age 2 years, and the outcome was defined as a filled prescription for a psychotropic agent after age 2 years., Results: For the 804 920 patients (51% males and 49% female) composing the study population, the mean age at first psychotropic prescription was 6.8 years. A total of 24 176 children (3%) were prescribed a proton pump inhibitor (PPI), 79 243 (10%) were prescribed a histamine-2 receptor antagonist (H2RA), and 607 348 (76%) were prescribed an antibiotic during the first 2 years of life. The adjusted hazard ratio (aHR) of a psychotropic prescription was significantly increased in children prescribed any H2RA (1.79; 95% CI, 1.63-1.96), PPI (1.47; 95% CI, 1.26-1.71), or antibiotic (1.71; 95% CI, 1.59-1.84). The aHR of psychotropic prescriptions increased commensurately with each additional antibiotic class added and with each additional class of medication (H2RA, PPI, or antibiotics) prescribed., Conclusions: Children prescribed antibiotic and acid suppressants in the first 2 years of life have a significant increase in future prescriptions for psychotropics, with a dose-related effect observed. This association represents a potential risk of early exposure to antibiotics and acid suppressants., (Published by Elsevier Inc.)

Background: Clostridioides difficile infection (CDI) has become a rising public health threat. Our study aims to characterize the epidemiology and measure the attributable cost, length of stay, and in-hospital mortality of healthcare facility-onset Clostridioides difficile infection (HO-CDI) among patients in the U.S. Military Health System (MHS)., Methods: We performed a case-control and cross-sectional inpatient study of HO-CDI using MHS database billing records. Cases included those who were at least 18 years of age admitted to a military treatment facility with a stool sample positive for C. difficile obtained >3 days after admission. Risk factors in the preceding year were identified. Patient case-mix adjusted outcomes including in-hospital mortality, length of stay, and hospitalization cost were evaluated by high-dimensional propensity score adjusted logistic regression., Results: Among 474,518 admissions within the MHS from 2008 to 2015, we identified 591 (0.12%) patients with HO-CDI and found a significant increase in the trend of HO-CDI over the 7-year study period (P < .001). Patients with HO-CDI had significantly higher hospitalization cost (attributable difference $66,044, P < .001), prolonged hospital stay (attributable difference 12.4 days, P < 0.001), and increased odds of in-hospital mortality (case-mix adjusted odds ratio 1.98; 95% CI, 1.43-2.74)., Conclusions: Healthcare facility-onset Clostridioides difficile infection is rising in patients within the MHS and is associated with increased length of stay, hospital costs, and in-hospital mortality. We identified a significantly increased burden of hospitalization among patients admitted with HO-CDI, highlighting the importance of infection control and antimicrobial stewardship initiatives aimed at decreasing the spread of this pathogen., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2021.

Objective: Toilet training is a major developmental milestone. Unsupervised periods combined with immature gross and fine motor skills may lead to toddler injuries during toilet training. Our aim was to investigate toilet-related injuries (TIs) in children., Methods: Data from the National Electronic Injury Surveillance System were used to evaluate emergency department encounters of children ages 0 to 6 years with TI from 2000 to 2019., Results: There were an estimated 142,606 children (95% confidence interval, 115,599-168,613) who presented to the emergency department for TI. Toilets were involved in 95% of injuries, and other potty chairs (PCs) involved 5% of injuries. Children had higher odds of sustaining head injury while using a toilet versus PC (adjusted odds ratio = 1.91; 95% CI, 1.06-3.45)., Conclusions: Toilet-related injuries present a high burden of risk to young children. Our data support that the safest vessel for use in toilet training is a PC/training seat as opposed to the toilet., (Copyright © 2021 Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a “work of the United States Government” for which copyright protection under Title 17 of the United States Code is not available.

Clostridioides difficile infection (CDI) in children is more often acquired in the community than in the hospital. Community-associated Clostridioides difficile infection (CA-CDI) cases seem to be rising, although this is confounded by the unclear role of C. difficile in children 1 and 3 years of age and overreliance on nucleic acid amplification tests for diagnosis. Exposure to antibiotics, acid suppression medications, health care settings, and close contacts with CDI are associated with CA-CDI in children. These infections are more common in children with chronic medical conditions, especially those involving the gastrointestinal tract and immune suppression. Most CA-CDI in children are mild and managed in the outpatient setting, but a small subset requires hospitalization and can be quite severe. Approximately 10% of children with CA-CDI experience a recurrence. Infection control guidance focuses on the hospital setting and future studies on the best methods for preventing community spread of C. difficile are needed., (© The Author(s) 2021.

Objective: To evaluate the relationship between parental injury and illness and disorders of gut-brain interaction (DGBI) in children., Study Design: A self-controlled case series using data from the Military Health System Data Repository compared International Classification of Diseases, Ninth Revision-identified DGBI-related outpatient visits and prescriptions in 442 651 children aged 3-16 years in the 2 years before and the 2 years after the injury and/or illness of their military parent. Negative binomial regression was used to compare visit rates for constipation, fecal incontinence, abdominal pain, irritable bowel syndrome, and a composite of these before and after parental injury and/or illness. Logistic regression, clustered by child, compared the odds of stooling agent and antispasmodic prescription before and after parental injury and/or illness., Results: In the 2 years following parental injury and/or illness, children had increased visits for DGBIs (adjusted incidence rate ratio [aIRR] 1.09; 95% CI 1.07-1.10), constipation (aIRR 1.07; 95% CI 1.04-1.10), abdominal pain (aIRR 1.09; 95% CI 1.07-1.12), and irritable bowel syndrome (aIRR 1.37; 95% CI 1.19-1.58). Following parental injury and/or illness, the odds of stooling agent prescription decreased (aOR 0.95; 95% CI 0.93-0.97) and the odds of antispasmodic prescription increased (aOR 1.26; 95% CI 1.18-1.36)., Conclusions: Parental injury and/or illness is associated with increased healthcare use for DGBIs. Parental health should be considered by clinicians when assessing DGBIs, counseling patients, and formulating treatment plans., (Published by Elsevier Inc.)

Objective: To assess the Uniformed Services Constipation Action Plan (USCAP) as an evidence-based, personalized, clinical action tool with pictograms to aid clinicians and families in the management of functional constipation., Study Design: The USCAP facilitates the management functional constipation by using a health literacy-informed approach to provide instructions for pharmacotherapies and lifestyle modifications. This study included part 1 (pictogram validation) and part 2 (assessment). For part 1, pictogram transparency, translucency, and recall were assessed by parent survey (transparency ≥85%, mean translucency score ≥5, recall ≥85% required for validation). For part 2, the USCAP was assessed by parents, clinical librarians, and clinicians. Parental perceptions (n = 65) were assessed using the Consumer Information Rating Form (17 questions) to gauge comprehensibility, design quality and usefulness. Readability was assessed by 5 formulas and a Readability Composite Score was calculated. Clinical librarians (n = 3) used the Patient Education Materials Assessment Tool to measure understandability (19 questions) and actionability (7 questions) (>80% rating was acceptable). Suitability was assessed by clinicians (n = 34) using Doak's Suitability Assessment of Materials (superior ≥70% rating)., Results: All 12 pictograms demonstrated appropriate transparency, translucency, and recall. Parental perceptions reflected appropriate comprehensibility, design quality, and usefulness. The Readability Composite Score was consistent with a fifth-grade level. Clinical librarians reported acceptable understandability and actionability. Clinicians reported superior suitability., Conclusions: The USCAP met all criteria for clinical implementation and future study of USCAP implementation for treating children with chronic functional constipation., (Published by Elsevier Inc.)

Introduction: Vancomycin-resistant enterococci (VRE) are classified by the Centers for Diseases Control and Prevention as a serious antibiotic resistance threat. Our study aims to characterize the epidemiology, associated conditions, and outcomes of VRE infections among hospitalized patients in the U.S. military health system (MHS)., Materials and Methods: We performed a retrospective cohort study of patients with VRE infection using the MHS database. Cases included all patients admitted to a military treatment facility for ≥2 days from October 2008 to September 2015 with a clinical culture growing Enterococcus faecalis, Enterococcus faecium, or Enterococcus species (unspecified), reported as resistant to vancomycin. Co-morbid conditions and procedures associated with VRE infection were identified by multivariable conditional logistic regression. Patient case-mix adjusted outcomes including in-hospital mortality, length of stay, and hospitalization cost were evaluated by high-dimensional propensity score adjustment., Results: During the seven-year study period and among 1,161,335 hospitalized patients within the MHS, we identified 577 (0.05%) patients with VRE infection. A majority of VRE infections were urinary tract infections (57.7%), followed by bloodstream (24.7%), other site/device-related (12.9%), respiratory (2.9%), and wound infections (1.8%). Risk factors for VRE infection included invasive gastrointestinal, pulmonary, and urologic procedures, indwelling devices, and exposure to 4th generation cephalosporins, but not to glycopeptides. Patients hospitalized with VRE infection had significantly higher hospitalization costs (attributable difference [AD] $135,534, P<0.001), prolonged hospital stays (AD 20.44 days, P<0.001, and higher in-hospital mortality (case-mix adjusted odds ratio 5.77; 95% confidence interval 4.59-7.25)., Conclusions: VRE infections carry a considerable burden for hospitalized patients given their impact on length of stay, hospitalization costs, and in-hospital mortality. Active surveillance and infection control efforts should target those identified as high-risk for VRE infection. Antimicrobial stewardship programs should focus on limiting exposure to 4th generation cephalosporins., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2021.

Objectives: Small rare-earth magnet (SREM) ingestions are a dangerous, potentially fatal health hazard in children. The U.S. Consumer Safety Commission removed these products from the market in 2012 until a federal court decision vacated this action in 2016. The present study aims to investigate whether the reintroduction of SREMs is associated with an increase in the national frequency of magnet ingestions in children., Patients and Methods: Data from the National Electronic Injury Surveillance System (NEISS) were used to evaluate suspected magnet ingestion (SMI) trends within patients (0-17 years) from 2009 to 2019. SMI cases were stratified (total, small/round, and multiple magnet ingestions) and trend analyses were performed for 2 periods: 2013-2016 (off-market) and 2017-2019 (on-market). National SMI estimates calculated using the NEISS-supplied weights and variance variables., Results: An estimated 23,756 children (59% males, 42% < 5 years old) presented with a SMI from 2009 to 2019 with an average annual case increase of 6.1% (P = 0.01). There was a significant increase in both small/round SMI encounters and multiple magnet ingestion encounters from 2009 to 2019 (P < 0.001 and P < 0.01, respectively). From 2017 to 2019, there was a greater proportion of small/round type SMIs to total SMIs estimated n = 541 (confidence interval [CI], 261-822) and a greater proportion of multiple magnet ingestions to total SMIs estimated n = 797 (CI, 442-1152) (both, P < 0.01). After 2017, there was a 5-fold increase in the escalation of care for multiple magnet ingestions (estimated n = 1094; CI 505-1686)., Conclusions: The significant increase in magnet ingestions by children from 2017 to 2019 indicates that regulatory actions are urgently needed to protect children and reverse these trends.

Background: The COVID-19 pandemic has drastically changed healthcare systems and training around the world. The Training Committee of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition sought to understand how COVID-19 has affected pediatric gastroenterology fellowship training., Methods: A 21 question survey was distributed to all 77 pediatric gastroenterology fellowship program directors (PDs) in the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition program director database via email on April 7. Responses collected through April 19, 2020 were analyzed using descriptive statistics., Results: Fifty-one of 77 (66%) PDs from the United States, Canada, and Mexico responded to the survey. Forty-six of 51 (90%) PDs reported that they were under a "stay-at-home" order for a median of 4 weeks at the time of the survey. Two of the 51 (4%) programs had fellows participating in outpatient telehealth before COVID-19 and 39 of 51 (76%) at the time of the survey. Fellows stopped participating in outpatient clinics in 22 of 51 (43%) programs and endoscopy in 26 of 51 (52%) programs. Changes to inpatient care included reduced fellow staffing, limiting who entered patient rooms, and rounding remotely. Fellows in 3 New York programs were deployed to adult medicine units. Didactics were moved to virtual conferences in 47 of 51 (94%) programs, and fellows used various online resources. Clinical research and, disproportionately, bench research were restricted., Conclusions: This report provides early information of the impact of COVID-19 on pediatric fellowship training. Rapid adoption of telehealth and reduced clinical and research experiences were important changes. Survey information may spur communication and innovation to help educators adapt.

Purpose of Review: The evidence supporting or contesting the prescription of proton pump inhibitors (PPIs) for children and updates on side effects are reviewed., Recent Findings: PPIs remain an important therapeutic option for esophagitis and gastritis. However, recent studies demonstrate no benefit when prescribing PPIs for chronic cough, infantile reflux, asthma, or functional gastrointestinal disorders. Recent studies suggest adverse effects on microbiome diversity and immune function, resulting in increased rates of gastrointestinal infections, bone fractures, and atopic disorders. PPIs influence a variety of cell types within the in the innate and adaptive immune systems. PPI prescriptions in children may be indicated for select conditions; however, multiple side effects and immune effects have been described. While most of these side effects are rare and mild, some studies suggest enduring adverse effects. Future studies to elucidate the mechanism behind some of these immune and infectious complications will be beneficial.

Background: We aimed to characterize the epidemiology, identify risk factors, and measure outcomes of carbapenem-resistant Enterobacteriaceae (CRE) infections among hospitalized patients., Methods: We performed a retrospective study of hospitalized patients with CRE infection using records from the US military health system database. Cases included patients admitted for ≥2 days from 2008-2015, with a clinical culture growing any Enterobacteriaceae reported as resistant to a carbapenem. Multivariable logistic regression was used to identify comorbid conditions and procedures associated with CRE infection, and a high-dimensional propensity score was used for a case-mix adjusted evaluation of CRE-associated in-hospital mortality, length of stay, and hospitalization costs., Results: From 1,162,686 hospitalized patients, we identified 143 with CRE infection over the 7-year study period. Conditions associated with CRE infection included manipulation of the gastrointestinal tract, musculoskeletal trauma, orthopedic procedures, septicemia, and both recent and remote exposure to broad-spectrum β-lactam antibiotics. Patients hospitalized with CRE infection had significantly higher hospitalization costs (attributable difference, $206,664; P < .001), longer hospital stays (attributable difference, 28.8 days; P < .001), and increased odds of in-hospital mortality (adjusted odds ratio, 3.34; 95% confidence interval, 1.82-6.12)., Conclusions: CRE are a significant threat to hospitalized patients. Our study quantifies the health care burden associated with CRE infection in the inpatient setting and highlights the importance of initiatives aimed at curbing the spread of these costly infections., (Published by Elsevier Inc.)

Objectives: There has long been an association between congenital heart disease (CHD) and general neurodevelopmental delays. However, the association between CHD and autism spectrum disorders (AuSDs) is less well understood. Using administrative data, we sought to determine the association between CHD and AuSD and identify specific CHD lesions with higher odds of developing AuSD., Methods: We performed a 1:3 case-control study of children enrolled in the US Military Health System from 2001 to 2013. Children with International Classification of Disease, Ninth Revision, Clinical Modification codes for AuSD were identified as cases and matched with controls on the basis of date of birth, sex, and enrollment time frame. Each child's records were reviewed for CHD lesions and associated procedures. Conditional logistic regression determined odds ratios (ORs) and 95% confidence intervals (CIs) for comparative associations., Results: There were 8760 cases with AuSD and 26 280 controls included in the study. After adjustment for genetic syndrome, maternal age, gestational diabetes, short gestation, newborn epilepsy, birth asphyxia, and low birth weight, there were increased odds of AuSD in patients with CHD (OR 1.32; 95% CI 1.10-1.59). Specific lesions with significant OR included atrial septal defects ( n = 82; OR 1.72; 95% CI 1.07-2.74) and ventricular septal defects ( n = 193; OR 1.65; 95% CI 1.21-2.25)., Conclusions: Children with CHD have increased odds of developing AuSD. Specific lesions associated with increased risk include atrial septal defects and ventricular septal defects. These findings will be useful for counseling parents of children with CHD., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

Identification and management of dyslipidemia in childhood can reduce future cardiovascular risk. We performed a retrospective cohort study of children ages 2 to 18 years during 2009 to 2013 to evaluate factors that affect screening and treatment of pediatric dyslipidemia related to 2011 National Heart, Lung, and Blood Institute (NHLBI) guidelines. Logistic regression analysis determined the impact of NHLBI-identified factors on odds of being screened, elevated low-density lipoprotein cholesterol (LDL-C), and receiving pharmacotherapy. A total of 1 736 032 children were included; 113 780 (6.6%) were screened for dyslipidemia. Screening in 9 to 11 year olds increased from 2009 to 2012. Of children screened, 18 801 (16.5%) had elevated LDL-C; 425 (2.3%) were treated pharmacologically. Parental dyslipidemia, diabetes mellitus, chronic kidney disease, Kawasaki disease, human immunodeficiency virus infection, nephrotic syndrome, liver, thyroid, and other endocrine disorders increased odds of screening. Older age, nephrotic syndrome, chronic kidney disease, diabetes mellitus, and hypertension increased odds of having elevated LDL-C and receiving treatment. Pediatric dyslipidemia screening rates remain low.

During the observance of Christmas, many families display decorations, which increases the risk of unfettered access and subsequent ingestion of small objects by children in the home. Our aim was to characterize the epidemiology of Christmas foreign body ingestion (CFBI) by children. National Electronic Injury Surveillance System data from 1997 to 2015 were obtained for children aged 0 to 17 years who presented to United States Emergency Departments matching "ingested" for "artificial Christmas trees"; "Christmas tree lights"; "Christmas tree stands or supports"; "Christmas decorations, nonelectric"; and "Christmas decorations, electric" (excluding tree lights). An estimated 22 224 children (95% confidence Interval = 18 107-26 340) presented to the emergency department for CFBI over the study period. Children aged 2 years and younger ingested Christmas objects most frequently ( P < .001). CFBI visits demonstrated a seasonal trend ( P < .001). Christmas decoration ingestions are a frequent reason for children to present to the ED, which require dedicated awareness for appropriate diagnosis and care.

Purpose: While gender dysphoria (GD) and autism spectrum disorder (ASD) are generally identified in isolation, research on individuals who are gender-referred or have autism suggests a possible overrepresentation of ASD in persons with GD and GD in persons with ASD. We investigated diagnosed GD in patients formally diagnosed with ASD and matched controls in the Military Health System., Methods: We performed a retrospective case-cohort study of GD diagnoses in children aged 2-18 years with and without ASD utilizing health care records from 2000 to 2013. Cases were formally diagnosed with ASD and matched to five controls by date of birth, gender marker, and enrollment time. Outpatient visits for GD were identified by relevant International Classification of Diseases, Ninth Revision codes. Logistic regression analysis determined odds ratios (ORs) and 95% confidence intervals (95% CIs) of GD diagnoses by ASD., Results: A total of 48,762 children with diagnosed ASD were identified, and each matched to five controls, for a total of 292,572 children. Cases and controls were each 80% assigned male at birth. The median end age of included children was 11.6 years. Of included children, 66 (0.02%) had diagnosed GD. Children with ASD were over four times as likely to be diagnosed with a condition indicating GD (OR 4.38 [95% CI 2.64-7.27], p < 0.001) compared with matched controls., Conclusion: This study corroborates previous research indicating an overrepresentation of GD in children with ASD. Further research is needed to understand the association and to demonstrate approaches to providing optimal care to these children.

Objective: Gut microbiota alterations are associated with obesity. Early exposure to medications, including acid suppressants and antibiotics, can alter gut biota and may increase the likelihood of developing obesity. We investigated the association of antibiotic, histamine-2 receptor antagonist (H2RA) and proton pump inhibitor (PPI) prescriptions during early childhood with a diagnosis of obesity., Design: We performed a cohort study of US Department of Defense TRICARE beneficiaries born from October 2006 to September 2013. Exposures were defined as having any dispensed prescription for antibiotic, H2RA or PPI medications in the first 2 years of life. A single event analysis of obesity was performed using Cox proportional hazards regression., Results: 333 353 children met inclusion criteria, with 241 502 (72.4%) children prescribed an antibiotic, 39 488 (11.8%) an H2RA and 11 089 (3.3%) a PPI. Antibiotic prescriptions were associated with obesity (HR 1.26; 95% CI 1.23 to 1.28). This association persisted regardless of antibiotic class and strengthened with each additional class of antibiotic prescribed. H2RA and PPI prescriptions were also associated with obesity, with a stronger association for each 30-day supply prescribed. The HR increased commensurately with exposure to each additional medication group prescribed., Conclusions: Antibiotics, acid suppressants and the combination of multiple medications in the first 2 years of life are associated with a diagnosis of childhood obesity. Microbiota-altering medications administered in early childhood may influence weight gain., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Objectives: Eosinophilic esophagitis (EoE) is an inflammatory, atopic disease of the esophagus without a clear etiology. Our objective was to identify exposures and conditions in early infancy associated with the development of EoE., Methods: A case-control study was performed using the Military Health System Database. Subjects diagnosed with EoE from October 2008 to September 2015 were matched 1:2 on age and sex. Early infant risk factors from the first 6 months of life were investigated., Results: A total of 1410 cases with EoE were matched to 2820 controls. The median (interquartile range) age at diagnosis of EoE was 4.2 years (2.1-7.2) and 68.7% were boys. Proton pump inhibitors (adjusted odds ratio [aOR], 2.73; 95% confidence interval [CI] 1.93-3.88), histamine-2 receptor antagonists (aOR, 1.64; 95% CI 1.27-2.13), and antibiotics (aOR, 1.31; 95% CI 1.10-1.56) were associated with EoE. Prematurity (aOR, 1.46; 95% CI 1.12-1.89) and early manifestations of atopic disease such as milk protein allergy (aOR, 2.37; 95% CI 1.26-4.44) and eczema (aOR, 1.97; 95% CI 1.64-2.36) were related to increased odds for EoE. Erythema toxicum in infancy was strongly associated with a diagnosis of EoE (aOR 3.52; 95% CI 1.03-12.04). Infants with feeding difficulty (aOR, 1.45; 95% CI 1.18-1.77) and gastroesophageal reflux disease (aOR, 1.79; 96% CI 1.43-2.26) were also at increased risk for EoE., Conclusions: Acid-blocking medications and antibiotics during infancy were associated with later diagnosis of EoE. Erythema toxicum neonatorum, an eosinophilic immune phenomenon, was strongly associated with EoE. Identifying early infant risk factors for EoE may help to risk stratify the need for endoscopy.

Background: We explored the association of 29 previously reported neonatal, perinatal, and prenatal conditions, and exposures with later diagnosis of autism spectrum disorder (ASD) in a large sample of children followed over multiple years., Methods: A retrospective case-cohort study was formed using the Military Health System database. Cases were identified by International Classification of Diseases, Ninth Revision codes for ASD between 2000 and 2013, and were matched 3:1 with controls on sex, date of birth, and enrollment time frame. Exposures included 29 conditions previously associated with ASD; 17 prenatal conditions and their pharmaceutical treatment, 5 perinatal conditions, and 6 neonatal conditions., Results: A total of 8,760 children diagnosed with ASD between the ages of 2 and 18 years were matched with 26,280 controls. ASD is associated with maternal mental illness, epilepsy, obesity, hypertension, diabetes, polycystic ovary syndrome, infection, asthma, assisted fertility, hyperemesis, younger maternal age, labor complications, low birth weight, infant infection, epilepsy, birth asphyxia, and newborn complications. The greatest increased risk was associated with infant epilepsy (odds ratio (OR) 7.57 (5.68-10.07)), maternal mental health (OR 1.80 (1.65-1.96)), and epilepsy (OR 1.60 (1.02-2.50)) medications., Conclusion: ASD is associated with a range of prenatal, perinatal, and neonatal factors, with the highest magnitude associations with maternal medication use and neonatal seizure.

Background: Hepatitis E virus (HEV) is a major cause of hepatitis in developing and industrialized countries worldwide. The modes of HEV transmission in industrialized countries, including the United States, remain largely unknown. This study is aimed at evaluating the association between HEV seropositivity and consumption of self-grown foods in the United States., Methods: Cross-sectional data was extracted from the 2009-2012 National Health and Nutrition Examination Survey (NHANES). Data from the dietary interview and the serum HEV IgG and IgM enzyme immunoassay test results were linked and examined. Univariate and multivariable logistic regression models were used to evaluate the significance and effect size of an association between self-grown food consumption and hepatitis E seropositivity., Results: The estimated HEV seroprevalence in the civilian, noninstitutionalized US population was 6.6% in 2009-2012, which corresponds to an estimated hepatitis E national seroprevalence of 17,196,457 people. Overall, 10.9% of participants who ingested self-grown foods had positive HEV antibodies versus 6.1% of participants who did not consume self-grown foods ( P < 0.001; odds ratio (OR) 1.87; 95% CI 1.41-2.48). In the age-stratified multivariable analysis, the correlation between ingesting self-grown foods and HEV seropositivity was significant for participants 40-59 years old, but not overall, or for those < 40 years or ≥60 years., Conclusions: Ingesting self-grown food, or simply the process of gardening/farming, may be a source of zoonotic HEV transmission.

Importance: Allergic diseases are prevalent in childhood. Early exposure to medications that can alter the microbiome, including acid-suppressive medications and antibiotics, may influence the likelihood of allergy., Objective: To determine whether there is an association between the use of acid-suppressive medications or antibiotics in the first 6 months of infancy and development of allergic diseases in early childhood., Design, Setting, and Participants: A retrospective cohort study was conducted in 792 130 children who were Department of Defense TRICARE beneficiaries with a birth medical record in the Military Health System database between October 1, 2001, and September 30, 2013, with continued enrollment from within 35 days of birth until at least age 1 year. Children who had an initial birth stay of greater than 7 days or were diagnosed with any of the outcome allergic conditions within the first 6 months of life were excluded from the study. Data analysis was performed from April 15, 2015, to January 4, 2018., Exposures: Exposures were defined as having any dispensed prescription for a histamine-2 receptor antagonist (H2RA), proton pump inhibitor (PPI), or antibiotic., Main Outcomes and Measures: The main outcome was allergic disease, defined as the presence of food allergy, anaphylaxis, asthma, atopic dermatitis, allergic rhinitis, allergic conjunctivitis, urticaria, contact dermatitis, medication allergy, or other allergy., Results: Of 792 130 children (395 215 [49.9%] girls) included for analysis, 60 209 (7.6%) were prescribed an H2RA, 13 687 (1.7%) were prescribed a PPI, and 131 708 (16.6%) were prescribed an antibiotic during the first 6 months of life. Data for each child were available for a median of 4.6 years. Adjusted hazard ratios (aHRs) in children prescribed H2RAs and PPIs, respectively, were 2.18 (95% CI, 2.04-2.33) and 2.59 (95% CI, 2.25-3.00) for food allergy, 1.70 (95% CI, 1.60-1.80) and 1.84 (95% CI, 1.56-2.17) for medication allergy, 1.51 (95% CI, 1.38-1.66) and 1.45 (95% CI, 1.22-1.73) for anaphylaxis, 1.50 (95% CI, 1.46-1.54) and 1.44 (95% CI, 1.36-1.52) for allergic rhinitis, and 1.25 (95% CI, 1.21-1.29) and 1.41 (95% CI, 1.31-1.52) for asthma. The aHRs after antibiotic prescription in the first 6 months of life were 2.09 (95% CI, 2.05-2.13) for asthma, 1.75 (95% CI, 1.72-1.78) for allergic rhinitis, 1.51 (95% CI, 1.38-1.66) for anaphylaxis, and 1.42 (95% CI, 1.34-1.50) for allergic conjunctivitis., Conclusions and Relevance: This study found associations between the use of acid-suppressive medications and antibiotics during the first 6 months of infancy and subsequent development of allergic disease. Acid-suppressive medications and antibiotics should be used during infancy only in situations of clear clinical benefit.

The Consumer Product Safety Risk Management System's injury and potential injury database records 13 cases of fidget spinner ingestion since 2016. In addition to a database query, we report 3 additional cases of fidget spinner ingestion to describe patient presentations and subsequent management strategies., (Published by Elsevier Inc.)

Autism spectrum disorders (ASD) and inflammatory bowel disease (IBD) both have multifactorial pathogenesis with an increasing number of studies demonstrating gut-brain associations. We aim to examine the association between ASD and IBD using strict classification criteria for IBD. We conducted a retrospective case-cohort study using records from the Military Health System database with IBD defined as having one encounter with an ICD-9-CM diagnostic code for IBD and at least one outpatient prescription dispensed for a medication to treat IBD. Children with ASD were more likely to meet criteria for Crohn's disease (CD) and Ulcerative colitis (UC) compared to controls. This higher prevalence of CD and UC in children with ASD compared to controls confirms the association of ASD with IBD.

Background and Objectives: Ingestion of rare earth magnets is a serious ongoing hazard for pediatric patients. Our study aims to investigate whether 2012 Consumer Product Safety Commission (CPSC) policy action, in coordination with efforts from consumer and physician advocacy groups, decreased the incidence of magnet ingestions in children in the United States since 2012., Methods: Data from the National Electronic Injury Surveillance System (NEISS) was used to evaluate trends in emergency department (ED) encounters with pediatric patients (<18 years) who presented with suspected magnet ingestions (SMI) from 2010 to 2015. National estimates of SMI were made using the NEISS-supplied weights and variance variables., Results: An estimated 14,586 children (59% male, 50% age <5 years) presented to the ED for SMI from 2010 to 2015. A significant upward trend in magnet-related ED visits preceded the CPSC action, with the peak ingestions of 3167 (95% confidence interval, 1612-4723) recorded in 2012. This was followed by a steady decrease in the rate of SMI to 1907 (95% confidence interval, 1062-2752) in 2015, an average annual decrease of 13.3%. Most importantly, post-federal action estimates demonstrated a downward trend in overall SMI ED visits (P = 0.03)., Conclusions: The frequency of magnet ingestions continued to rise from 2010 and then peak in 2012, followed by a decline in magnet ingestion ED visits during the post-federal action years. This down trend emphasizes the importance of advocacy on decreasing magnet ingestions in children. Further study will be required to determine the impact of the court decision to lift the magnet ban in 2016.

Background: Urolithiasis is rare in pediatric patients. All patients with inflammatory bowel disease (IBD) have an increased risk of urolithiasis, but this risk is poorly quantified in children. The objective of this study is to evaluate the association of IBD with urolithiasis, assess surgical outcomes, and analyze the financial burden for children hospitalized with urolithiasis and comorbid IBD., Methods: The triennial Healthcare Cost and Utilization Project Kids' Inpatient Database for years 1997 to 2012 was used to evaluate the association between urolithiasis and IBD in hospitalized, nonpregnant children ages 5 to 20 years old. Billing codes were used to define conditions. Logistic regression analysis quantified the association between IBD types and urolithiasis. Length of hospital stay, costs, procedures, and complications were compared between urolithiasis patients with and without IBD., Results: Among 8,828,522 hospital admissions, we identified 36,771 admissions with a primary diagnosis of urolithiasis. Of these cases, 230 were associated with Crohn's disease (odds ratios, 1.99; 95% confidence interval, 1.74-2.27) and 102 with ulcerative colitis (odds ratio, 1.63; 95% confidence interval, 1.34-1.99). Urolithiasis patients with ulcerative colitis, but not Crohn's disease, had significantly increased length of stay and costs. Patients with either IBD had a decreased number of urologic procedures., Conclusions: The diagnosis of urolithiasis in pediatric patients is associated with IBD, and those with ulcerative colitis have longer hospital stays and greater costs. Patients with IBD have fewer urologic procedures associated with their urolithiasis diagnosis.

Objective: To evaluate the incidence, trends, seasonality, and age at the time of hepatoportoenterostomy (Kasai procedure) for biliary atresia in the US., Study Design: The triennial Health Cost and Utilization Project-Kids' Inpatient Database for 1997-2012 was used to perform a retrospective analysis of biliary atresia in the US. Infants aged <1 year of age with a diagnosis of biliary atresia who underwent a Kasai procedure were included. Nationwide infant population data were used to calculate incidence and evaluate trends. Age at the time of the Kasai procedure and the seasonality of biliary atresia were evaluated as well., Results: The incidence of biliary atresia in the US was 4.47 per 100 000 and was higher in females (risk ratio [RR], 1.43; 95% CI, 1.27-1.62), Asian/Pacific Islanders (RR, 1.89; 95% CI, 1.44-2.47), and blacks (RR, 1.30; 95% CI, 1.06-1.58) compared with whites. The incidence of biliary atresia increased by an average of 7.9% per year from 1997 to 2012 (P <.001). The median age at the time of the Kasai procedure was 63 days, with no improvement over the study period (P = .64). There was no evidence of seasonality (P = .69)., Conclusion: The incidence of biliary atresia has increased over the past 15 years, with the median age at the time of the Kasai procedure now outside the optimal window. Implementation of systematic screening measures for biliary atresia in the US are needed., (Published by Elsevier Inc.)

Objective: To characterize the medication and other exposures associated with pediatric community-associated Clostridium difficile infections (CA-CDIs)., Study Design: We performed a case-control study using billing records from the US military health system database. CA-CDI cases included children 1-18 years of age with an outpatient International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic code for Clostridium difficile infection (CDI) from 2001 to 2013. Each case was matched to 3 controls without CDI by age and sex. Children hospitalized at any time before their CDI were excluded. Outpatient pharmacy records were used to identify medication exposures in the preceding 12 weeks. In addition, we evaluated recent outpatient healthcare exposure, exposure to a sibling younger than 1 year of age, or to a family member with CDI., Results: A total of 1331 children with CA-CDI were identified and 3993 controls were matched successfully. Recent exposure to fluoroquinolones, clindamycin (OR 73.00; 95% CI 13.85-384.68), third-generation cephalosporins (OR 16.32; 95% CI 9.11-29.26), proton pump inhibitors (OR 8.17; 95% CI 2.35-28.38), and to multiple classes of antibiotics, each was associated strongly the subsequent diagnosis of CA-CDI. Recent exposure to outpatient healthcare clinics (OR 1.35; 95% CI 1.31-1.39) or to a family member with CDI also was associated with CA-CDI., Conclusions: CA-CDI is associated with medications regularly prescribed in pediatric practice, along with exposure to outpatient healthcare clinics and family members with CDI. Our findings provide additional support for the judicious use of these medications and for efforts to limit spread of CDI in ambulatory healthcare settings and households., (Published by Elsevier Inc.)

Focal dermal hypoplasia (FDH) is a rare disorder of the mesodermal and ectodermal tissues. Here we present an eight-year-old female known to have FDH who presents with poor weight gain and dysphagia. She was diagnosed with multiple esophageal papillomas and eosinophilic esophagitis. She was successfully treated with argon plasma coagulation and ingested fluticasone propionate, which has not been described previously in a child., Competing Interests: Conflict-of-interest statement: The authors have no disclosures. This case report discusses use of the ERBE VIO APC system (ERBE USA Inc, Marietta, Georgia) and the proprietary PRECISE setting. The authors have no affiliation with ERBE.

Background: The diagnosis and management of eosinophilic esophagitis (EoE) often requires multiple endoscopies. Serum biomarkers can be elevated in EoE patients, but their clinical utility in diagnosis and assessing response to treatment is not well established., Goals: To evaluate serum biomarkers in EoE subjects compared with controls and assess longitudinally in response to treatment., Study: We conducted a prospective cohort study of children and adults undergoing esophagogastroduodenoscopy for suspected EoE. After completing an 8-week course of proton-pump inhibitor therapy, esophageal mucosal biopsies were obtained, as well as, serum analysis of absolute eosinophil count (AEC), eotaxin-3, eosinophil-derived neurotoxin (EDN), eosinophil cationic protein (ECP) and interleukin-5. Subjects with normal endoscopic and histologic findings constituted controls. Those meeting criteria for EoE underwent repeat esophagogastroduodenoscopy and biomarker measurements following treatment with topical steroids for 8 weeks., Results: Median levels of AEC (263.50 vs. 102 cu/mm, P<0.001), ECP (26.98 vs. 5.20 ng/mL, P<0.001) and EDN (31.70 vs. 14.18 ng/mL, P=0.004) were significantly elevated in EoE subjects compared with controls and correlated with esophageal eosinophilia. Levels of AEC (odds ratio, 1.79; 95% confidence interval, 1.28-2.64) and ECP (odds ratio, 1.61; 95% confidence interval, 1.23-2.36) were associated with a diagnosis of EoE. Among the 5 biomarkers evaluated, only AEC significantly predicted esophageal eosinophilia following topical steroid therapy in EoE subjects (P=0.006)., Conclusions: AEC, ECP, and EDN were higher in EoE subjects compared with controls and correlated with degree of esophageal eosinophilia. Furthermore, AEC predicted post-treatment eosinophilia, suggesting a potential role in monitoring EoE disease activity.

Objectives: To assess for an increased risk of obesity, type 2 diabetes mellitus, hypertension, hyperlipidemia, and nonalcoholic fatty liver disease/nonalcoholic steatohepatitis in children with autism spectrum disorders (ASD). Additionally, to determine the rates of prescribed treatment for obesity-related metabolic disorders and to determine whether treatment with psychotropic medications is associated with the development of obesity for children with ASD., Study Design: A retrospective 1:5 case-control study was performed by use of the Military Health System database from October 2000 to September 2013. For children with ASD and matched controls, International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes for obesity, type 2 diabetes mellitus, hypertension, hyperlipidemia, nonalcoholic fatty liver disease/nonalcoholic steatohepatitis, and prescriptions were obtained. Conditional logistic regression determined ORs and 95% CIs., Results: A total of 48 762 individuals with ASD and 243 810 matched controls were identified. Children with ASD had significantly greater odds of having obesity (OR 1.85; 95% CI 1.78-1.92), having obesity-related disorders, and being prescribed a medication when they had these diseases. In children with ASD, mood stabilizers, antipsychotics, antiepileptic drugs, and selective serotonin reuptake inhibitors were associated with obesity., Conclusions: Children with ASD have an increased risk of obesity and obesity-related metabolic disorders. They are more likely to be prescribed medications to treat these complications, suggesting they may have more severe disease. There is a significant association between the use of some psychotropic categories and a diagnosis of obesity, suggesting that obesity in children with ASD may be partially iatrogenic., (Published by Elsevier Inc.)

Objectives: Eosinophilic esophagitis (EoE) can present as food selectivity or feeding disorders in children. Children with autism spectrum disorders (ASDs) commonly demonstrate behavioral food selectivity in type and texture, which often leads to the diagnosis of feeding disorder. We sought to evaluate the association of ASD with EoE., Methods: A retrospective matched case-cohort study was performed using the Military Health System database from October 2008 to September 2013. We performed a 1:5 case-control match by age, sex, and enrollment timeframe. Feeding disorders, EoE, and atopic disorders were defined using diagnostic and procedure codes., Results: There were 45,286 children with ASD and 226,430 matched controls. EoE was more common in children with ASD (0.4%) compared with controls (0.1%). Feeding disorders were associated with EoE in both children with ASD and controls. Feeding disorders also had a higher odds ratio for EoE compared with other atopic conditions, among both children with ASD (7.17, 95% confidence interval [CI] 4.87-10.5) and controls (11.5, 95% CI 7.57-17.5). Compared with controls with a feeding disorder, children with ASD and a feeding disorder had no difference in the rate of diagnosed EoE (0.85, 0.95% CI 0.39-1.88)., Conclusions: Children with ASD are more likely to be diagnosed with EoE compared with controls; however, among children with feeding disorders, there is no difference in the odds of EoE. A diagnosis of feeding disorder was strongly associated with EoE. Feeding disorders in children with ASD should not be assumed to be solely behavioral and an esophagogastroduodenoscopy should be performed to evaluate for EoE.
