AIMS To study the role of maternal employment status as indicator of socioeconomic status in the origin of isolated orofacial clefts (OFC) and in the use of periconceptional folic acid/multivitamin supplementation. METHODS 1,975 cases with OFC (1,374 cases with cleft lip +/- palate and 601 cases with posterior cleft palate), 38,151 population controls without any defects and 20,868 patient co...

AIM The aim of this study was to compare hospital admissions from infancy to adulthood, between children born with orofacial clefts (OFC) and those without OFC. METHODS The method used was a cohort study using record-linked administrative datasets. Participants included all children liveborn in Western Australia (WA) between 1980 and 2010 diagnosed with OFC, who were frequency matched by year...

BACKGROUND Clefts of the lip and palate are the most common significant congenital birth anomaly of the orofacial region. The condition may vary from a minor easily correctable cleft to a significant functional and cosmetic incapacitation. This is the first epidemiological study of orofacial clefts in the Negev region in Israel. OBJECTIVES To establish the frequency of cleft lip and palate in...

BACKGROUND Non-syndromic cleft lip with or without cleft palate (CL/P) or cleft palate only (CPO) are orofacial clefts with multifactorial etiology. These include environmental factors and heterogeneous genetic background. Therefore, studies on different and homogenous populations can be useful in detecting related factors. The aim of the present study was to evaluate the risk factors in patien...

Previous work suggested that cleft lip with or without cleft palate (CL/P) is genetically distinct from isolated cleft secondary palate (CP). Mutations in the Bmp target gene Msx1 in families with both forms of orofacial clefting has implicated Bmp signaling in both pathways. To dissect the function of Bmp signaling in orofacial clefting, we conditionally inactivated the type 1 Bmp receptor Bmp...

BACKGROUND Maternal use of corticosteroids during early pregnancy has been inconsistently associated with orofacial clefts in the offspring. A previous report from the National Birth Defect Prevention Study (NBDPS), using data from 1997 to 2002, found an association with cleft lip and palate (odds ratio, 1.7; 95% confidence interval [CI], 1.1-2.6), but not cleft palate only (odds ratio, 0.5, 95...

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...

Much remains to be understood about the differential contributions from primary and secondary sensory cortices to sensory-guided decision making. To address this issue we simultaneously recorded activity from neuronal ensembles in primary [gustatory cortex GC)] and secondary gustatory [orbitofrontal cortex (OFC)] cortices while rats made a taste-guided decision between two response alternatives...

Van der Woude syndrome (VWS) is usually underreported and frequently not diagnosed. The phenomenon that cleft lip and palate are regularly combined in the same pedigree makes it unique. A meticulous examination of a patient with lip pits may reveal a hidden form of a cleft, for example, submucous. This paper presents a case of VWS in a ten-year-old boy with characteristic orofacial features. Sp...

We numerically study the dynamics of a discrete spring-block model introduced by Olami, Feder, and Christensen (OFC) to mimic earthquakes and investigate to what extent this simple model is able to reproduce the observed spatiotemporal clustering of seismicity. Following a recently proposed method to characterize such clustering by networks of recurrent events [J. Davidsen, P. Grassberger, and ...
