Abstract
PURPOSE To investigate the occupational and environmental factors in the etiology of infantile hypertrophic pyloric stenosis (IHPS). METHODS Protocol was drafted according to the PRISMA guidelines and registered on PROSPERO (CRD42020152460). A search for a combination of terms related to IHPS, fetus and neonates, and environmental exposure was performed for studies published between 2000 and 2020 in the EMBASE, Pubmed, and MEDLINE databases. RESULTS Overall, 2203 abstracts were identified and 829 were screened. The full text of the selected articles (N = 98) was assessed for eligibility. Fifteen studies were included in quantitative synthesis. IHPS risk was significantly lower in black and Hispanic mothers than in white mothers [OR 0.47 (95% CI 0.44-0.51, p < 0.001), OR 0.85 (95% CI 0.77-0.94, p = 0.002), respectively]. Lower maternal education level and maternal smoking were risk factor for IHPS. We further observed a non-significant association between maternal folic acid usage and IHPS risk. Data were insufficient to evaluate occupational exposure. CONCLUSION This review provides an understanding of the role of environmental exposures in IHPS etiology. Lower maternal educational level, maternal smoking, and white ethnicity are associated with a significantly increased risk of IHPS, while folic acid use seems non-significantly associated with IHPS risk. LEVEL OF EVIDENCE III.

Abstract
The etiology of pediatric abdominal disorders is poorly understood, and the relationship with maternal mental health is understudied. We sought to determine the association between maternal psychiatric disorders and abdominal conditions in childhood. We performed a retrospective cohort study of 1,080,518 newborns in Quebec, Canada, between 2006 and 2020. We identified maternal mental disorders before or during pregnancy and computed the incidence of abdominal disorders in offspring before 1 year of age. Outcomes included Hirschsprung disease; hypertrophic pyloric stenosis; and esophageal, intestinal, and biliary atresia. We calculated adjusted risk ratios (RR) with 95% confidence intervals (CI) for the association of maternal mental disorders with these pediatric abdominal disorders. Among 51,371 children exposed to maternal mental disorders, 200 children had an abdominal condition, for a rate of 38.9 cases per 10,000 children (95% CI 33.6-44.3) compared with 27.7 per 10,000 for children who were unexposed to maternal mental disorders (95% CI 26.7-28.7). Compared with no mental disorder, maternal mental disorders were associated with hypertrophic pyloric stenosis (RR 1.39, 95% CI 1.16-1.68). Associations were stronger for severe mental disorders and were more marked for depression and stress and anxiety disorders. Maternal mental disorders are associated with the risk of hypertrophic pyloric stenosis in offspring. The origin of hypertrophic pyloric stenosis may relate to maternal mental disorders that were present during pregnancy.

Protocol: A systematic review and meta-analysis of the role of fetal and infantile environmental exposure in etiopathogenesis of infantile hypertrophic pyloric stenosis. PLoS One 2021; 16:e0247003. [PMID: 33592043 PMCID: PMC7886114 DOI: 10.1371/journal.pone.0247003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Accepted: 01/27/2021] [Indexed: 01/10/2023] Open
Abstract
Infantile hypertrophic pyloric stenosis (IHPS) is one of the hallmark pediatric surgical diseases. However, its etiology remains incompletely understood. By systematically reviewing the literature, we aim to clarify the effect of the effect of occupational and environmental factors and role of nitric oxide (NO) metabolism in the etiopathogenesis of IHPS. The systematic review is drafted with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement (PRISMA) and the Meta-analysis of Observational Studies in Epidemiology (MOOSE). Systematic literature search will be performed for the period 2000 (Jan) to 2020 (Dec) in the databases: MEDLINE, EMBASE, PubMed. The systematic search will cover the literature in English and Turkish language and will be limited to studies on human subjects. Four investigators will independently search the databases (MEDLINE, EMBASE, PubMed) according to the defined search strategy. The full-text of the selected articles will be screened independently by four reviewers, against the inclusion criteria. Descriptive data will be extracted from each study regarding: study details, methods, participants, outcomes and calculations of association for potential further statistical analysis. If meta-analysis could not be undertaken, systematic approach to analyzing the findings of included multiple studies will be described. Heterogeneity will be assessed by quantifying the inconsistency across studies using I2 statistic. Statistical analysis will be performed using Comprehensive Meta-Analysis Version 3.0 software. The p values lower than 0.05 will be considered statistically significant for all analyses.

Prevalence and descriptive epidemiology of infantile hypertrophic pyloric stenosis in the United States: A multistate, population-based retrospective study, 1999-2010. Birth Defects Res 2018; 111:159-169.

Abstract
BACKGROUND Antecedents for infantile hypertrophic pyloric stenosis (IHPS) vary across studies; therefore, we conducted a multistate, population-based retrospective study of the prevalence and descriptive epidemiology of IHPS in the United States (US). METHODS Data for IHPS cases (n = 29,554) delivered from 1999-2010 and enumerated from 11 US population-based birth defect surveillance programs, along with data for live births (n = 14,707,418) delivered within the same birth period and jurisdictions, were analyzed using Poisson regression to estimate IHPS prevalence per 10,000 live births. Additional data on deliveries from 1999-2005 from seven of these programs were analyzed using multivariable logistic regression to estimate adjusted prevalence ratios (aPR)s and 95% confidence intervals (CI)s for selected infant and parental characteristics. RESULTS Overall, IHPS prevalence from 1999-2010 was 20.09 (95% CI = 19.87, 20.32) per 10,000 live births, with statistically significant increases from 2003-2006 and decreases from 2007-2010. Compared to their respective referents, aPRs were higher in magnitude for males, preterm births, and multiple births, but lower for birth weights <2,500 g. The aPRs for all cases increased with decreasing parental age, maternal education, and maternal parity, but decreased for parental race/ethnicity other than non-Hispanic White. Estimates restricted to isolated cases or stratified by infant sex were similar to those for all cases. CONCLUSIONS This study covers one of the largest samples and longest temporal period examined for IHPS in the US. Similar to findings reported in Europe, estimates suggest that IHPS prevalence has decreased recently in the US. Additional analyses supported associations with several infant and parental characteristics.

Abstract
BACKGROUND Infantile hypertrophic pyloric stenosis (IHPS) is the most common surgical cause of nonbilious vomiting in infancy. The etiology of IHPS is not completely understood. Hence, we performed a meta-analysis to investigate the association between perinatal factors and IHPS onset. METHODS The MEDLINE, EMBASE, PubMed and Cochrane Library databases were searched for studies published in English before December 2016. The combined odd ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects models. RESULTS Fifteen studies were included. Several perinatal factors, including first-born (OR 1.19, 95% CI: 1.07-1.33), cesarean section delivery (OR 1.63, 95% CI: 1.53-1.73), preterm birth (OR 1.37, 95% CI: 1.12-1.67), and bottle-feed (OR 2.46, 95% CI: 1.76-3.43), were significantly associated with the IHPS onset. Among these, bottle-feed was the most significantly risk factor for IHPS onset. Although few studies have evaluated the relationship between perinatal factors and IHPS, they have major limitations including retrospective collection of data on perinatal events and testing of multiple hypotheses without appropriate statistical corrections. CONCLUSIONS First-born, cesarean section delivery, preterm birth, and bottle-feed are associated with the development of IHPS. Well-designed future studies are needed to help understand the etiology of IHPS. TYPE OF STUDY Systematic reviews and meta-analyses. LEVEL OF EVIDENCE Level III.
