Objective: To investigate the association between pregnancy planning and orofacial clefts in the United Kingdom. Design: Case–control study. Setting: Scotland and the Manchester and Merseyside regions of England. Participants: One hundred and ninety-one children born with nonsyndromic orofacial cleft, 1997 to 2000, and 247 controls. Main outcome measure: Cleft lip with and without cleft palate, and cleft palate. Results: There was an inverse association between planning for pregnancy and orofacial cleft in the offspring (odds ratio [OR] = 0.51, 95% confidence interval [CI] = 0.33–0.79). An unplanned pregnancy together with smoking in the first trimester of pregnancy resulted in almost treble the risk of a child with an orofacial cleft when compared with those who planned their pregnancy and did not smoke (OR = 2.92, CI = 1.50–5.65). Conclusions: Planned pregnancies were associated with a lower risk of orofacial clefts. Isolation of the elements of pregnancy planning implicated in these results is difficult. Current preconception advice needs to reach a wider audience; however, for maximum impact, efforts are needed to reduce the numbers of unplanned pregnancies.

Abstract Background A growing body of studies have investigated the association between air pollution exposure during early pregnancy and the risk of orofacial clefts, but these studies put more emphasis on particulate matter and reported inconsistent results, while research on the independent effects of gaseous air pollutants on orofacial clefts has been quite inadequate, especially in China. Methods A case–control study was conducted in Changsha, China from 2015 to 2018. A total of 446 cases and 4460 controls were included in the study. Daily concentrations of CO, NO2, SO2, O3, PM2.5 and PM10 during the first trimester of pregnancy were assigned to each subject using the nearest monitoring station method. Multivariate logistic regression models were applied to evaluate the associations of monthly average exposure to gaseous air pollutants with orofacial clefts and its subtypes before and after adjusting for particulate matter. Variance inflation factors (VIFs) were used to determine if the effects of gaseous air pollutants could be independent of particulate matter. Results Increase in CO, NO2 and SO2 significantly increased the risk of cleft lip with or without cleft palate (CL/P) in all months during the first trimester of pregnancy, with aORs ranging from 1.39 to 1.48, from 1.35 to 1.61 and from 1.22 to 1.35, respectively. The risk of cleft palate only (CPO) increased with increasing NO2 exposure levels in the first trimester of pregnancy, with aORs ranging from 1.60 to 1.66. These effects sustained and even exacerbated after adjusting for particulate matter. No significant effect of O3 was observed. Conclusions Our study suggested that maternal exposure to CO, NO2, and SO2 during the first trimester of pregnancy might contribute to the development of orofacial clefts, and the associations were potentially independent of particulate matter.

Introduction: Cleft lip and/or palate is a congenitally persistent space affecting orofacial region. It is generally divided into cleft lip (CL), cleft palate (CP) and cleft lip with cleft palate (CLP). The objective of the study was to evaluate distribution of patterns of orofacial clefts according to sex and laterality; predisposing factors and other congenital anomalies associated with cleft lip and/or palate. Materials & Method: A cross-sectional descriptive type of study was carried out using in 268 patients having cleft lip and/or palate. Types of clefts, predominance of sex and laterality, familial history, associated anomalies and drug and disease history of mother were recorded. Result: The results revealed 23.51% CL, 54.85% CLP and 21.64% CP. There were 58.21% males and 41.79% females. Positive family history of cleft was present in 28.0% and associated anomalies were observed in 3.7% of the cleft subjects. Mothers of 6.0% of the total patients were exposed to teratogenic agents during first trimester of pregnancy. Conclusion: It was concluded that among the three types of cleft (CL, CP and CLP), CLP is the most common type. The males are affected more with cleft lip and/or palate than the females. Clefts also have risks of associated congenital anomalies. Exposure to teratogenic agents in first trimester of pregnancy is also associated with orofacial cleft.

The Difference

ABSTRACT The fractional determination of 17-ketosteroids in the daily urine was performed in nine cases of hyperemesis gravidarum and in four control cases, in the first trimester of pregnancy both before and after corticotrophin administration. The excretion of total 17-KS is similar in the two groups. Only in the hyperemesis group does the excretion of total 17-KS increase significantly after corticotrophin administration. The fractional determination reveals no difference between the two groups of patients with regard to the values of the fractions U (unidentified 17-KS), A (androsterone) and Rest (11-oxygenated 17-KS). The excretion of dehydroepiandrosterone is significantly higher in the hyperemesis group than in the control group. The excretion of androstanolone seems to be lower in the hyperemesis group than in the control group, but the difference is not statistically significant. The differences in the correlation between dehydroepiandrosterone and androstanolone in the two groups is significant. The high excretion of dehydroepiandrosterone and low excretion of androstanolone in cases of hyperemesis gravidarum is a sign of adrenal dysfunction.
