Increased urinary levels of angiotensin-converting enzyme 2 and of Ang-(1-7) in fetuses with posterior urethral valve could represent a regulatory response to the intense inflammatory process triggered by posterior urethral valve.
This study shows that inflammatory molecules are already increased in fetuses with PUV at the mean gestational age of 22 weeks, suggesting a physiopathological role for inflammation just after the embryological formation of the urethral membrane.
Congenital syngnathia is a maxillomandibular fusion, and it can vary in severity from single mucosal bands (synechiae) to complete bony fusion (synostosis). Cases of combinations of bony or soft tissue adhesions between the mandible and maxilla with cleft of the lip or palate, aglossia, popliteal pterygium, and van der Woude syndrome have been reported. It is a very rare condition, with only one case report of prenatal diagnosis using two-dimensional ultrasound in the literature. We present the first case of prenatal diagnosis of congenital syngnathia by three-dimensional ultrasound and the postnatal pathology correlation.
Electronic poster abstractsimage: 3D volume to 2D dicom images using DICOMatic (TomoVision).Step 2. Pre-processing: Gaussian filter for reducing the noise of 2D cross-section.Step 3. Iterative Binary method: applied different thresholds for each image in consideration of the characteristics of each section (2D image) to separate only the region of the fetus.Step 4. Post-processing: morphologic operation applied for segmentation of the meaningful area of the fetus.Step 5. Modeling and visualization: smoothing after surface rendering. 3D model was provided in the form of a stl file after completing all processing. Results: We applied these algorithms for 3D ultrasound volume data of fetal face and fetal heart between 19 and 29 completed gestational weeks. We successfully created 3D printing of fetal face and fetal heart with commercial 3D printer. Conclusions: Preliminary experiments indicate good results in image segmentation from 3D ultrasound data and 3D printing of fetus. It can be used for numerical analysis and creation of a physical model by 3D Printer.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
