The aim of the study is to summarize the current state of knowlege in the diagnosis and monitoring of patients with alveolar echinococcosis (AE), using serological tests and imaging techniques, and to present the most recent therapeutic guidelines based on a literature review. The paper discusses the challenges in diagnosing and treating AE encountered in clinical practice in Poland, based on the analysis of medical records of 86 patients with AE, who were hospitalized in the University Centre for Maritime and Tropical Medicine (UCMTM) between 2000 and 2018. In Poland, AE is usually diagnosed at the advanced stage, when optimal, radical surgery is not an option. Diagnosis of AE is often preceded by invasive diagnostic methods, such as biopsy or exploratory laparotomy, which may result in the infection spreading. Pharmacological treatment is associated with potential adverse effects and is a significant financial burden for the patient due to the lack of reimbursement. There is a need to raise the awareness of AE among physicians performing imaging studies and to facilitate access to modern techniques enabling the assessment of the parasitic process.

SUMMARY OBJECTIVES To review the literature and the diagnosis of conventional histopathological routine and immunohistochemistry of the cases diagnosed with Solid Pseudopapillary Neoplasm of the Pancreas (SPNP). METHODS The review of the literature was done using the Pubmed and solid Google-Scholar databases, through the historical, clinical aspects and diagnostic methods of SPNP. The review of SPNP cases diagnosed in the University Hospital Clementino Fraga Filho was carried out from 1977 to 2018. RESULTS Intratumoral phenotypic heterogeneity of SPNP was evidenced in the cases studied, taking into account macroscopic, microscopic, and immunohistochemical patterns. CONCLUSIONS The results show the importance of the examination of several fragments obtained from different regions of the neoplasia since not all of them present the same molecular alterations.

This paper will review the current state of understanding of interface structure and highlight some of the future needs and problems which must be overcome. The study of this subject can be separated into three different topics: 1) the fundamental electron microscopy aspects, 2) material-specific features of the study and 3) the characteristics of the particular interfaces. The two topics which are relevant to most studies are the choice of imaging techniques and sample preparation. The techniques used to study interfaces in the TEM include high-resolution imaging, conventional diffraction-contrast imaging, and phase-contrast imaging (Fresnel fringe images, diffuse scattering). The material studied affects not only the characteristics of the interfaces (through changes in bonding, etc.) but also the method used for sample preparation which may in turn have a significant affect on the resulting image. Finally, the actual nature and geometry of the interface must be considered. For example, it has become increasingly clear that the plane of the interface is particularly important whenever at least one of the adjoining grains is crystalline.A particularly productive approach to the study of interfaces is to combine different imaging techniques as illustrated in the study of grain boundaries in alumina. In this case, the conventional imaging approach showed that most grain boundaries in ion-thinned samples are grooved at the grain boundary although the extent of this grooving clearly depends on the crystallography of the surface. The use of diffuse scattering (from amorphous regions) gives invaluable information here since it can be used to confirm directly that surface grooving does occur and that the grooves can fill with amorphous material during sample preparation (see Fig. 1). Extensive use of image simulation has shown that, although information concerning the interface can be obtained from Fresnel-fringe images, the introduction of artifacts through sample preparation cannot be lightly ignored. The Fresnel-fringe simulation has been carried out using a commercial multislice program (TEMPAS) which was intended for simulation of high-resolution images.

The work aims to provoke critical educational reflections on the current state of the scientific-pedagogical conception of inclusive education in the university context. In this sense, we are aware of the existence of an extremely positive conceptual evolution in recent times. It is necessary to articulate new discourses and teaching practices that project and illuminate the idea that inclusive education as a permanent process of change in education and for which the development of psychological activities outlined in resilience can play an important role. The Ecuadorian higher education system has experienced, for a few years, changes of great pedagogical interest. In this framework, a whole process of generating educational policies and inclusive education is shown, taking as a framework the professors and managers of the Technical University of Manabí (UTM) (Ecuador), to contribute to the greater inclusive development of the said university. The main challenges for university institutions regarding fostering the resilience of the academic process are presented.

Abstract The archaeological site of the Domus Romana in Rabat, Malta was excavated almost 100 years ago yielding artefacts from the various phases of the site. The Melite Civitas Romana project was designed to investigate the domus, which may have been the home of a Roman Senator, and its many phases of use. Pending planned archaeological excavations designed to investigate the various phases of the site, a team from the Institute for Digital Exploration from the University of South Florida carried out a digitization campaign in the summer of 2019 using terrestrial laser scanning and aerial digital photogrammetry to document the current state of the site to provide a baseline of documentation and plan the coming excavations. In parallel, structured light scanning and photogrammetry were used to digitize 128 artefacts in the museum of the Domus Romana to aid in off-site research and create a virtual museum platform for global dissemination.

Abstract Species of the genus Echinococcus (Cestoda; Taeniidae) are minute tapeworms of carnivores. Their larvae are known as hydatids (metacestode), which proliferate asexually in various mammals. Like the majority of cestodes, Echinococcus spp. require two different host species to complete their life cycle. Definitive hosts harbouring the adult cestodes in the small intestine are exclusively carnivores of the Canidae and Felidae families. A wide range of mammal species including humans is susceptible to infection by the metacestode of Echinococcus spp., which develops in their viscera. The disease, caused by species of the genus Echinococcus, is called echinococcosis, and it is one of the most dangerous zoonoses in the world. The traditional species Echinococcus granulosus and Echinococcus multilocularis are agents of significant diseases due to the high number of cases and the wide geographical species range. The taxonomy of the genus is controversial; in the current state of ongoing complex revisions, the agent of cystic echinococcosis E. granulosus sensu lato is divided into five species (E. granulosus sensu stricto, E. felidis, E. equinus, E. ortleppi, E. canadensis), in addition to the agents of alveolar echinococcosis (E. multilocularis, E. shiquicus) and polycystic/unicystic echinococcosis (E. vogeli, E. oligarthrus). Here we provide an overview of the current situation, which continues to develop.

Background. Additive technologies are increasingly making their way from university laboratories and high-tech industries into routine clinical practice and even into our everyday lives. Any enthusiast, having a PC and a 3D printer at his or her disposal, can create any physical object — from children’s toys to works of art. The presence on the market of a wide range of software pro-ducts, equipment, and consumables along with the data from mo-dern diagnostic methods, a high level of training and cooperation between doctors and engineers provide practical medicine with unprecedented opportunities. We are finally able to fully customize our treatment and diagnostic procedures: to perform precise preoperative planning; to draw up a detailed plan of the operation; to rehearse the intervention on full-scale anatomical prototypes using a standard tool; to conduct the surgery as quickly and atraumatically as possible; to minimize risks; to ensure the optimal functional result and to manufacture and install customized implants in the most difficult cases. The purpose was to draw the attention of our distinguished colleagues to the aspects of application of additive technologies in modern orthopaedic practice, to introduce them into the history and current state of medical prototyping, as well as to share technological nuances with them. Materials and methods. While writing this article, we incorporated the data of recent publications in specialized domestic and foreign periodicals, several monographs, materials from thematic conferences, the results of informal conversations with colleagues in the operating rooms, at the computer and production site, as well as our own experience (over 200 cases of prototyping). Conclusions. The availability of equipment, software, and consumables allows for the introduction of additive technology into the everyday practice of nearly every modern orthopaedic and trauma clinic.

The object of this paper is one of the most ancient palaces of Naples, Palazzo Penne, a fourteenth-century residential building located on a small high ground which originally was in the outer fringe of the built up area in a privileged position enabling to enjoy the landscape and gulf beauty. This building, which today is in the heart of the historical center, was the subject of an extensive analysis and documentary research, as well as of metric laser scanner survey carried out by the group researchers working at the Interdepartmental Centre of Research Urban Eco of the University of Naples Federico II. <br><br> Starting from <i>scan to bim</i> systems the creation of a parametric model of the current state of the building is completed, by bringing the point cloud elements back to objects to which historical and construction data can be associated. <br><br> Moreover starting from acquired data, the 3D model shows the reconstructive hypothesis of the original structure and the virtual reconstruction of the building based on traces found on-site and on the comparison with coeval creations allowing to properly hypothesize the design of point features.
