Prevalence of infantile hypertrophic pyloric stenosis in Texas, 1999–2002

Abstract

This study confirmed previous findings that female infants and Black infants have a lower rate of IHPS. Large decreases in rates of IHPS were observed among foreign-born Hispanics and foreign-born Asians, but not among their US-born counterparts. These findings may be explained by differences in the frequency of behavioral risk factors for IHPS or differences in the frequency of ascertainment of mild cases of IHPS by ethnicity or nativity.

Descriptive epidemiology of nonsyndromic omphalocele in Texas, 1999–2004

“…The apparent association between nonsyndromic omphalocele and U.S. birthplace among Hispanics that was observed in this study is consistent with previous findings that foreign born Hispanic women in the U.S. are less likely to have offspring with congenital malformations than are native U.S. born Hispanics [Carmichael et al, 2004;Zhu et al, 2006;Vu et al, 2008;Wang et al, 2008]. However, these previous studies did not include omphalocele.…”

Epidemiology of nonsyndromic conotruncal heart defects in Texas, 1999–2004

“…Several studies have previously reported that Hispanic women born outside of the United States are less likely to have offspring with specific types of congenital malformations (e.g., central nervous system defects, omphalocele) than U.S.-born Hispanic women (Carmichael et al, 2004;Zhu et al, 2006;Wang et al, 2008;Agopian et al, 2009). However, in this study, there was no evidence that the risk of TA, d-TGA, or TOF differed for the offspring of U.S.À and non-U.S.Àborn Hispanic mothers.…”

Decline in Infantile Hypertrophic Pyloric Stenosis in Germany in 2000–2008

“…5,6 A white male preponderance (4-5:1) and increased risk in patients' families are well documented. [7][8][9] Young maternal age also appears to be a risk factor, 10 according to recent epidemiologic data from the European surveillance of congenital anomalies (EUROCAT). 11 Currently, the etiology of IHPS is unclear.…”
