Multiple congenital anomalies (MCAs) are defined as two or more unrelated major structural malformations that cannot be explained by an underlying syndrome or sequence. The percentage and combination patterns of MCAs were analyzed using the European surveillance of congenital anomalies computer algorithms for nationwide data on congenital anomalies after assisted reproductive technology between 2004 and 2009 in Japan. There were a total of 177,548 pregnancies and 124,846 live births. About 7% (96/1,324) were MCAs. Although most maternal/neonatal outcomes between the isolated cases group and the MCAs group were similar, higher early neonatal death rate was observed in the MCAs group than in the isolated cases group (9.8% versus 3.7%, resp.). Regarding the major organ system subcategory in ICD-10, the rate of MCAs was around 30% in “congenital malformations of eye, ear, face, and neck,” “congenital malformations of the respiratory system,” and “congenital malformations of genital organs.” On the other hand, the rate of MCAs was less than 10% in “congenital malformations of the circulatory system.” The combination patterns of diseases were widely varied. Of them, two or three diseases of the circulatory system, the digestive system, and the musculoskeletal system tended to co-occur in the same individuals.

Introduction. The use of  sisted reproductive technologies has had sufficient experience to reduce the risks associated with the technologies themselves. But pediatricians remain concerned about the health of children born from induced pregnancies because of the influence of the parents’ initial health on perinatal outcomes. Congenital malformations remain socially significant, the risk of which may be higher for children from induced pregnancy.Objective: to evaluate the effect of initial parental health and the methods of assisted reproductive technology used on the formation of congenital malformations and minor anomalies in children from singleton induced pregnancies.Materials and Methods. A retrospective cohort study was conducted using data on live-born children from singleton induced pregnancy born at the Avicenna Medical Center (Novosibirsk) over the period from 2007 to 2017 (n = 409). The reproductive, somatic, and infectious history of the parents and the methods of assisted reproductive technology used were assessed. Parental fertility treatment up to childbirth was performed in the same center, which ensured complete continuity of follow-up. Differences between the groups of children from SIP with and without congenital anomalies were determined using Pearson’s chi-squared test.Results and discussion. We found that children with congenital malformations and minor anomalies were more often born as a result of subsequent pregnancies; thawed embryos transferred at the blastocyst stage were used in assisted reproductive technology programs (p < 0.05); exacerbations of herpes type 2 infection were diagnosed during the current pregnancy (p < 0.05). In the group of children with only CM, the parents had a longer history of infertility (8.3 ± 1.2) years; pregnancy was achieved by transferring fresh embryos at the blastocyst stage (in 68.2% of cases). In the group of children without congenital malformations and minor anomalies, the maternal infectious history was more severe: there were significantly more frequent cases of urogenital infections (p < 0.05) and exacerbations of herpes simplex virus type 1 during pregnancy (p < 0.05).Conclusion. A set of measures aimed at an earlier solution of the infertility problem is necessary for the primary prevention of congenital abnormalities associated with the age and duration of parental infertility.

Background and Objective. The first step in the search for the genetic basis of oral clefts should be the well-accepted classification and clinical data protocols, which are important in distinguishing separate phenotypic groups. The aim of this study was to compare the frequency of congenital malformations associated with oral clefts between the different groups of oral clefts. Material and Methods. The study population comprised 238 patients with oral clefts and one or more major congenital anomalies. All cases of oral clefts were subdivided into 2 groups: patients with the recognized conditions (n=97, 40.8%) and patients with the multiple congenital anomalies of unknown origin (n=141, 59.2%). The frequency of associated congenital anomalies was compared between the cleft palate (CP) and cleft lip and/or palate (CL/P) groups as well as between the cleft lip only (CL) and cleft lip with cleft palate (CLP) subgroups. Results. A total of 420 anomalies associated with oral clefts were diagnosed in 141 patients with multiple congenital anomalies (2.98 anomalies per proband) with the highest incidence being in the CP group (3.5 anomalies per proband). Comparison of the CP and CL/P groups showed that some of associated congenital anomalies such as atresia and stenosis of the small intestine and micrognathia occurred significantly more often in the CP than CL/P group (2.1% vs. 0% and 3.5% vs. 1.1%; P<0.05). Meanwhile, comparison of the CL and CLP subgroups revealed accessory auricle, other specified anomalies of the ear, congenital anomalies of the circulatory system, and certain congenital musculoskeletal deformities of the spine to be more common in the CL than CLP group (5.1% and 0.5%, 11.9% and 5.1%, 3.4% and 0%, 3.4% and 0%, respectively; P<0.05). Conclusions. The highest incidence of associated congenital anomalies was in the CP group followed by the CL, CL/P, and CLP groups. Generally, the anomalies of the musculoskeletal system, cardiovascular system, and face including eye, ear, and neck were most common. The careful analysis of associated anomalies and cases of oral cleft subgroups with multiple congenital anomalies is helpful in identifying the etiologic entities and underscores the need for thorough evaluation and competent distinction of various types of oral clefts.
