AbstractThis systematic review aims to determine the diagnostic accuracy of fetal MRI for detecting cleft palate in fetuses at risk for orofacial clefts. Pubmed, Embase, and CINAHL were searched systematically. A diagnostic study was included if it performed MRI (index test) and postnatal examination (reference test) in fetuses at risk for orofacial clefts. Methodological quality was assessed using the QUADAS-2. A meta-analysis was performed with a random-effects model, calculating the pooled sensitivity, specificity, and area under the curve. The search resulted in eight studies (334 fetuses) to be included: four prospective and four retrospective studies. The applicability concern was low. There was, however, a risk of selection and information bias. All studies showed that MRI well predicted the chance of cleft palate. The sensitivity results were homogeneous, but heterogeneity was assumed regarding the specificity estimate (Cochrane’s Q test: p = 0.00). The pooled sensitivity was 0.97 (95% CI 0.93–0.99); the pooled specificity was 0.94 (0.89–0.97). The area under the curve was 0.98 (95% CI 0.98–0.99).Conclusion: This meta-analysis shows that MRI has an excellent sensitivity and good to excellent specificity for diagnosing cleft palate in fetuses at risk for orofacial clefts. Future research should assess applicability for clinical care.What is Known:• Using ultrasound for prenatal detection of cleft palate leads to misdiagnosis frequently.• MRI could potentially improve the prenatal detection rate of cleft palate.What is New:• Eight studies describe the diagnostic accuracy of MRI for detecting cleft palate.• Combined results show excellent sensitivity and good to excellent specificity.

The goal of our study was investigation of prenatal diagnostics of pathology and distribution of associated anomalies in the group of children - patients of clinic with congenital maxillofacial anomalies. Basing on oral poll of mothers given birth to children with the pathology during the period 2012-2014 in Krasnodarskii krai (358 cases), the efficiency of prenatal detection of congenital clefts of lip and palate (diagnosis Q36, Q35 and Q37 by MKB-10) by ultrasonic investigation was studied. Prenatal 2D ultrasonic investigation is performed three times during pregnancy on 12, 18-24 and 32-34 weeks of pregnancy. Cleft lip or palate were detected on the second and third ultrasonic investigation: cleft palate (Q35) was revealed only in 5,6% cases of children born with cleft palate, and cleft palate (Q36 and Q37) - in 33,8% cases. Importance of prenatal ultrasonic diagnostics of pathology is not only predetermined by the necessity of mental conditioning of parents for the most urgent and proper rehabilitation of ill children, but, also, by the fact that patients with clefts of lip or palate frequently have associated pathology of other organs and chromosomal anomaly. For proper prenatal detection of cleft palate 3D ultrasonic investigation is necessary. We also studied the presence of associated pathology distribution for the cases of isolated clefts of lip or palate. Higher efficiency of cleft lip and palate detection in prenatal period by ultrasonic diagnostics would support more successful rehabilitation by well-timed mental conditioning and informing of parents about stages of rehabilitation in the process of child growing. Ethical aspects of probable abortion because of detected pathology during ultrasonic investigation.

Objective. To evaluate the three-dimensional ultrasound paper cleft lip and palate deformities in applications in prenatal diagnosis. Methods. 25 cases of cleft lip and palate fetus, 20–32 weeks of gestational age, with the maternal age of 22–44 years, were examined by prenatal ultrasound in our hospital; conventional two-dimensional ultrasound examination was performed after a cleft lip, and the application of three-dimensional ultrasound imaging surface and a transparent imaging showed the alveolar process and the palate of the fetus. Also, the results of two-dimensional ultrasound and postnatal (or after induction) results were compared. Results. Of the 25 cases, there were 6 cases of postpartum induction or simply unilateral cleft lip, 17 cases of unilateral cleft palate, and two cases of bilateral cleft lip palate. There was no significant ( P > 0.05 ) difference of two- and three-dimensional ultrasound detection rate of pure cleft lip; two-dimensional ultrasound cleft palate detection rate was 36.8% (7/19), and three-dimensional ultrasound cleft palate detection rate was 89.5% (17/19). The two methods showed a statistically significant ( P < 0.05 ) difference in the detection rate of cleft palate. Conclusion. Three-dimensional ultrasound can significantly improve the diagnostic accuracy of prenatal cleft palate.

I should like to give you a very condensed progress report on some spectrophotometric measurements of objective-prism spectra made in collaboration with H. Leicher at Bonn. The procedure used is almost completely automatic. The measurements are made with the help of a semi-automatic fully digitized registering microphotometer constructed by Hög-Hamburg. The reductions are carried out with the aid of a number of interconnected programmes written for the computer IBM 7090, beginning with the output of the photometer in the form of punched cards and ending with the printing-out of the final two-dimensional classifications.

Definition Of

1. The definition of “normal” stars in spectral classification changes with time; at the time of the publication of theYerkes Spectral Atlasthe term “normal” was applied to stars whose spectra could be fitted smoothly into a two-dimensional array. Thus, at that time, weak-lined spectra (RR Lyrae and HD 140283) would have been considered peculiar. At the present time we would tend to classify such spectra as “normal”—in a more complicated classification scheme which would have a parameter varying with metallic-line intensity within a specific spectral subdivision.

“Dynamical mixing”, i.e. relaxation of a stellar phase space distribution through interaction with the mean gravitational field, is numerically investigated for a one-dimensional self-gravitating stellar gas. Qualitative results are presented in the form of a motion picture of the flow of phase points (representing homogeneous slabs of stars) in two-dimensional phase space.

AbstractIn this paper we present complete two-dimensional measurements of the observed brightness of the 9th November 1990Hαflare, using a PDS microdensitometer scanner and image processing software MIDAS. The resulting isophotal contour maps, were used to describe morphological-cum-temporal behaviour of the flare and also the kernels of the flare. Correlation of theHαflare with SXR and MW radiations were also studied.
