UNLABELLED Congenital heart malformations represent a public health problem, holding a significant percentage of the total of heart diseases. Beside the elevated frequency of the malformations, we also notice their occurrence in newborn babies with low birth weight, increasing, thus, the risk of complications and late therapeutic approach. The goal of the study was to highlight the general and ...
The use of sequential segmental analysis for describing congenital heart malformations was the method of assessment used in a prospective necropsy study covering Jutland, a well defined geographical and demographic area of Denmark. The study group was 1,154 children of whom 261 (22.6%) had a congenital heart malformation. The most common malformations were ductus arteriosus and ventricular sept...
BACKGROUND Prior investigations have not identified a major locus for vertebral malformations, providing evidence that there is genetic heterogeneity for this condition. WNT3A has recently been identified as a negative regulator of Notch signaling and somitogenesis. Mice with mutations in Wnt3a develop caudal vertebral malformations. Because congenital vertebral malformations represent a sporad...
OBJECTIVES To examine whether infertile couples (with a time to pregnancy of > 12 months), who conceive naturally or after treatment, give birth to children with an increased prevalence of congenital malformations. DESIGN Longitudinal study. SETTING Danish national birth cohort. PARTICIPANTS Three groups of liveborn children and their mothers: 50,897 singletons and 1366 twins born of fert...
(Abstracted from J Pediatr 2022;244:148–153) Congenital heart defects are the most common cause of infant death linked to congenital malformations (CHDs). This group disorders therefore remains a for concern, despite improvements in medical and surgical management that have resulted higher survival rates.
BACKGROUND Orofacial clefts are usually isolated cases but can be associated with other congenital malformations that are either recognised or unrecognised syndromes. The reported prevalence and pattern of such associated malformations, however, vary among studies. OBJECTIVES To assess the frequencies and aetiologies of congenital malformations and associated medical conditions in children wi...
Background: Obstructive gastrointestinal (GI) malformations are one of the most important congenital problems and have different clinical manifestations, which depend on the severity and location. Although, complete obstructive lesions cause classic intestinal obstructive symptoms in infants, incomplete obstruction might be asymptomatic until adulthood and sometimes cause unusual symptoms, whic...
Ductal plate malformations are a heterogenous group of congenital fibrocystic liver diseases resulting from insult to the ductal plate at various stages of embryogenesis. As a result various biliary malformations, cysts, hamartomas and congenital hepatic fibrosis may be seen. We present a radiological pictorial of ductal plate malformations, accurate diagnosis of which is important for clinical...
