Hypertrophic Pyloric Stenosis (hypertrophic + pyloric_stenosis)

[source] Hypertrophic pyloric stenosis and pulmonary hypertension in a neonate.ACTA PAEDIATRICA, Issue 6 2009A common mechanism? Abstract Nitric oxide (NO) is an important mediator of biological functions. Absence or shortage of NO plays a role in the pathogenesis of both hypertrophic pyloric stenosis and persistent pulmonary hypertension. We present a neonate diagnosed with pulmonary hypertension after birth caused by meconiumaspiration syndrome eventually treated with extracorporal membrane oxygenation followed by hypertrophic pyloric stenosis for which a pyloromyotomy was performed. In conclusion, the association of pulmonary hypertension and pyloric stenosis has not been described before and may be explained by a lowered plasma concentration of arginine leading to deficient NO synthesis in the affected organ systems. [source] Cystic fibrosis and infantile hypertrophic pyloric stenosis: Is there an association?PEDIATRIC PULMONOLOGY, Issue 5 2002Khalid S. Kakish MD Abstract Cystic fibrosis (CF) is the most common lethal genetic disease among Caucasian populations. The generally accepted incidence of CF in the United States is 1 in 3,200 in the Caucasian population. Intestinal obstructions and atresias have been described among patients with CF. An association of CF with infantile hypertrophic pyloric stenosis (IHPS) has not been previously documented. A review in our clinic of 72 patients with CF revealed IHPS in two. The incidence of 2.7% is greater than the 0.3% incidence expected in the general population. This ninefold increase in IHPS in patients with CF suggests an association between the two and warrants further investigation. Pediatr Pulmonol. 2002; 33:404,405. © 2002 Wiley-Liss, Inc.

[source] A Quantitative Study of the Neural Changes Underlying Pyloric Stenosis in DogsANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 3 2002R. M. Abel Summary This study aimed to quantify the neural changes in congenital pyloric stenosis in dogs and to study the comparative anatomy between this condition in dogs and that in infantile hypertrophic pyloric stenosis. Eight specimens from the pylorus of dogs with pyloric stenosis and six control specimens were examined using conventional histology and immunohistochemistry for a range of neural antigens. The changes in the proportion of nerves immunoreactive for each antigen were quantified and analysed statistically. The morphology of the nerves in the diseased dogs was similar to that in controls. Only vasoactive intestinal peptide was reduced in expression in dogs (median proportion in control dogs 0.57, in diseased dogs 0.17; P = 0.065). This study demonstrates both morphological similarities and significant differences between closely related conditions in dogs, humans and other species. [source] Risks of selected congenital malformations among offspring of mixed race-ethnicityBIRTH DEFECTS RESEARCH, Issue 10 2004Juan Yang Abstract BACKGROUND Little is known about the occurrence of specific congenital malformations among offspring of mixed race-ethnicity. METHODS Using data from a population-based registry, we explored the occurrence of selected malformation phenotypes in offspring to parents who were of different race-ethnicity. Data were derived from the California Birth Defects Monitoring Program, a population-based active surveillance system for collecting information on infants and fetuses with congenital malformations using multiple source ascertainment. Approximately 2.6 million live births and stillbirths occurred during 1989,2000. Information on parental race-ethnicity (non-Hispanic white, Hispanic, black, and Asian) was obtained from birth certificates and fetal death files. Malformation phenotypes studied were spina bifida, anencephaly, cleft lip, cleft palate, tetralogy of Fallot, d-transposition of great arteries, hypospadias, small intestinal atresia, preaxial polydactyly, microtia, and hypertrophic pyloric stenosis. RESULTS A total of 11.2% of births were to parents of mixed race-ethnicity. Compared to births of parents who were both white, moderately increased risks (risk ratio , 1.7) of anencephaly, polydactyly, and microtia, and decreased risks (risk ratio , 0.6) of hypospadias and hypertrophic pyloric stenosis were observed among births of several mixed race-ethnicity groups. For anencephaly, polydactyly, and microtia, but not other phenotypes, the risks were different depending on whether maternal versus paternal race-ethnicity was considered. Risks observed between births of a nonwhite parent and a white parent and births of parents who were both nonwhite were similar for most malformation phenotypes. CONCLUSIONS Some malformation phenotypes appear to vary in their risk based on mixed racial-ethnic groupings. Birth Defects Research (Part A), 2004. © 2004 Wiley-Liss, Inc.
