“…To our knowledge, no previous literature reported a diverse collection of neonatal and infantile fistula. Most of the reported literatures concentrated upon a single type of them [13][14][15]. GIT and urinary fistulas are the most common fistulas enrolled in this series.…”

Background: Neonatal and infantile fistulas are diverse and include many types. Conventional contrast images are used to delineate the fistulous tracts. The aim of this study is to illustrate the conventional radiological spectrum of neonatal and infantile fistula with surgical correlation. Methods: Neonates and infants with suspected fistulas were included in this study. The patients may be presented by cutaneous fistula with discharge, profuse oral secretion and cyanosis on feeding, or imperforate anus. After full clinical data were taken, plain X-ray, contrast imaging, and abdominal sonography were done to the patients. Treatment was tailored according to the case. Results: Our study included 34 patients (25 boys and 9 girls): one case of branchial fistula; 2 cases with thyroglossal fistula; 10 cases of tracheo-esophageal, esophago-cutaneous, and esophago-pleural fistulas; 3 cases with vitello-intestinal fistula; one case with urachal fistula; 12 cases with recto-urinary, recto-vaginal, and recto-perineal fistula; 4 cases with peri-anal fistulas; and finally one case with iatrogenic urethra-cutaneous fistula. Radiological findings were well correlated with the surgical data. Conclusion: Many types of neonatal and infantile fistulas were shown in this series including tracheoesophageal, recto-urinary, and other neonatal fistulas. Radiological and surgical data were well matched.

The paper presents in its initial part historical notes to the development of digital signal and image processing methods. The following case studies are devoted to their application in biomedicine and they include the use of computational intelligence in EEG and EMG signal processing, image segmentation and registration in orthodontia, the human-machine interaction and the three-dimensional modelling using MS Kinect in diagnostics and treatment of human motion disorders and neurological diseases. Associated comments include remarks and references to the development of modern computational tools, biosensors, wireless communication and data fusion used in assistive technologies and robotic systems. Mathematical tools common to all these applications form the next part of the paper that includes notes to spectral analysis, functional transforms, digital filtering, image enhancement, classification of multi-dimensional signal components and optimization using neural networks. Final remarks emphasize the interdisciplinary significance of the digital signal processing forming the integrating basis of many diverse research areas.Index Termshistory of digital signal and image processing, computational intelligence, digital signal processing methods, computer aided biomedical diagnostics and treatment, Microsoft Kinect three-dimensional modelling

“…These regions of interest were then used to estimate the dental arch parameters. The coordinates of evaluated tops of each tooth were used [34] for parabolic approximation of the dental arch by a function f (x) = c 1 x 2 + c 2 x + c 3 (4) for x in a range of minimum and maximum values on the horizontal axes. The coefficients of this function formed further measures associated with each dental arch.…”

Augmented reality has a wide range of applications in many areas that can extend the study of real objects into the digital world, including stomatology. Real dental objects that were previously examined using their plaster casts are often replaced by their digital models or three-dimensional (3D) prints in the cyber-physical world. This paper reviews a selection of digital methods that have been applied in dentistry, including the use of intra-oral scanning technology for data acquisition and evaluation of fundamental features of dental arches. The methodology includes the use of digital filters and morphological operations for spatial objects analysis, their registration, and evaluation of changes during the treatment of specific disorders. The results include 3D models of selected dental arch objects, which allow a comparison of their shape and position during repeated observations. The proposed methods present digital alternatives to the use of plaster casts for semiautomatic evaluation of dental arch measures. This paper describes some of the advantages of 3D digital technology replacing real world elements and plaster cast dental models in many areas of classical stomatology.
