Oral and Maxillofacial SurgerySurvey of congenital anomalies associated with cleft lip and/or palate in 701,181 Japanese people☆
Section snippets
Method
Each delivery facility in the Tokai area informed us annually of its number of births, from which we conducted a survey of babies born with CL/CLP. This survey recorded the month of birth, sex, birth weight, and associated congenital anomalies of every baby with CL/CLP. The survey period was 12 years and covered 701,181 births, which accounted for 53.7% of the 1,305,030 births in this area. The main subjects of this survey were 1063 newborns with CL/CLP. Some birth weight records or details
Results
Table I provides an incidence order of the congenital anomalies.
Discussion
Although cases of congenital anomalies associated with CL/CLP have been reported by many hospitals, the data differ among hospitals. For example, many cases were from general hospitals that have neonatal intensive care units, whereas few patients with associated anomalies are introduced to the dental hospitals attached to universities like ours. Therefore, we investigated associated congenital anomalies in Japan by surveying child-delivery facilities. Although this method is effective for

Functional involvement of caleosin/peroxygenase PdPXG4 in the accumulation of date palm leaf lipid droplets after exposure to dioxins
2021, Environmental PollutionCitation Excerpt :The toxicity of dioxins in animals involves a well characterized pathway, the Aryl Hydrocarbon Receptor (AHR), a ligand-dependent transcription factor that mediates a range of biological and toxicological responses (Poland et al., 1978). Nowadays, it is well recognized that TCDD causes wasting syndrome, thymic atrophy and cleft palate in rats, mice and hamsters, respectively, (Bastomsky, 1977; Huuskonen et al., 1994; Yamada et al., 2006; Kransler et al., 2007), with similar birth defects in humans accidentally exposed to dioxins also reported (Natsume et al., 2001; Parker et al., 2010). TCDD is also well known as a potent suppressor of immune responses in laboratory animals, causing serious defects in animal resistance to infectious disease (McConkey et al., 1988).
Is an isolated cleft lip an isolated anomaly?
2011, Journal of Plastic, Reconstructive and Aesthetic SurgeryCitation Excerpt :Accompanying congenital defects were present in 10% of our total subject group. The last outcome parallels figures in other studies.19–21 Some anomalies were trivial and, often, patients (scoliosis, pectus, congenital nevus, etc.) needed no intervention.
