“…While a linear correlation between SIDS and IHPS rates does indeed exist, we have demonstrated that the decline in IHPS preceded the fall in SIDS in Scotland. Furthermore, the lack of marked seasonal variation in the Scottish IHPS incidences confirms the findings of Sule and colleagues,15 and is in marked contrast to the seasonal variation seen in SIDS deaths 13 14…”

“…The rate of IHPS in the USA ranges from 1.7 to 2.4 per 1000 LB [2, 3] and in the UK from 1.4 to 4.4 per 1000 LB [4, 5]. Infantile hypertrophic pyloric stenosis occurs predominantly in boys compared with girls (4.2 : 1), and in Whites compared with Blacks (2.8 : 1) and compared with Asians (5 : 1) [3, 6].…”

IntroductionAbdominal ultrasonography has replaced barium studies in establishing the diagnosis in difficult cases of infantile hypertrophic pyloric stenosis (IHPS). The aim of this retrospective study was to establish sonographic criteria of qualification for surgical treatment in children with IHPS.Material and methodsHundred and fifteen infants (98 boys and 17 girls) with suspected IHPS were treated between 2000 and 2009. Pyloric muscle thickness, pyloric diameter and pyloric length were measured in US scans in all patients. Results were compared with US results of 19 infants with negative diagnosis and 29 children of the reference group.ResultsDiagnosis of IHPS was confirmed by US examination in 96 children (83.5%). There were 86 boys in the group with male prevalence 8.6 : 1. The remaining 19 infants (16.5%) had a negative ultrasound. The mean PL (20.89 vs. 12.73), PMT (5.41 vs. 2.24), and PD (14.1 vs. 7.42) differed significantly between patients with and without pyloric stenosis (p < 0.0001). The mean PL (12.34), PMT (2.2), and PD (7.48) in the reference group did not differ statistically from values obtained in patients with negative IHPS diagnosis and were significantly lower than in children from the IHPS group (p < 0.0001). US imaging had a sensitivity of 98%, specificity of 100%, with a positive and negative predictive value of 100% and 90% respectively.ConclusionsThis study confirmed that ultrasonography is the first choice of diagnostic method in an infant with suspected hypertrophic pyloric stenosis. In cases with an uncertain clinical diagnosis of IHPS the examination can be easily repeated.

“…A previous review has suggested an increased predisposition for IHPS in populations living in temperate regions of North America and Western Europe compared to those in tropical countries (Spicer, 1982). Reported prevalence estimates (per 10,000 live births) for IHPS range from 17 to 50 in the United States (US) (Applegate & Druschel, 1995;Markel, Proctor, Ying, & Winchester, 2015;Schechter, Torfs, & Bateson, 1997;St Louis et al, 2017) and Western Europe (de Laffolie, Turial, Heckmann, Zimmer, & Schier, 2012;Hedback, Abrahamsson, Husberg, Granholm, & Oden, 2001;O'Donoghue et al, 1993;Pedersen et al, 2008;Sommerfield et al, 2008;Sule, Stone, & Gilmour, 2001). Some populations in Western Europe have reported declines in IHPS prevalence across different birth periods from the 1980s through the 2000s, although others have not (de Laffolie et al, 2012;O'Donoghue et al, 1993;Pedersen et al, 2008;Sommerfield et al, 2008).…”

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.
