With Phenotypic Signs of Connective Tissue Dysplasia: Cross-Sectional Clinical Study

Background. The dental health is an integral part of a person's well-being. Students of higher educational institutions comprise a health risk group, since they experience extensive physiological changes and personal socialization. The impact of connective tissue dysplasia on dental health is a relevant research task.Objective. To analyze the correlation between dental pathology and phenotypic signs of connective tissue dysplasia in first-year students.Methods. A cross-sectional clinical study of the dental health and phenotypic signs of connective tissue dysplasia was conducted as part of routine dental examination of 263 first-year students of KubSMU, aged 18–23. All participants were divided into 2 groups: group 1 – participants with 0-2 signs of connective tissue dysplasia (n = 108); group 2 – participants with 3 or more signs of dysplasia (n = 155). Statistical analysis of the results was carried out using Microsoft Excel 2010 and Statistica 6.0.Results. Unsatisfactory and poor oral hygiene levels in the group of participants with connective tissue dysplasia outnumber these levels in the control group by 30% and 22%, with very poor level in the second group 2.3 times higher (p ≤ 0.05). The incidence of noncarious tooth pathology in individuals with dysplasia is 26% higher than in the control group. The caries intensity index in group 2 is almost 20% bigger than in the control group. As expected, the group of participants with no signs of dysplasia revealed better periodontal health, namely 51.85% versus 45.81% (p ≤ 0.05). In terms of mucosal pathology, a statistical significant difference between groups 1 and 2 was noted for traumatic injuries (16.35% and 19.35%, respectively). Dentofacial abnormalities were observed more often in individuals with 3 or more phenotypic signs of connective tissue dysplasia.Conclusion. Higher morbidity rate of caries and noncarious pathology in the group of first-year students with 3 or more phenotypic signs of connective tissue dysplasia, compared to the group with 0–2 phenotypic manifestations of dysplasia, indicated the need to create a database of the dentofacial profiles of students, develop an algorithm for regular medical check-up of students, as well as provide differentiated preventive and therapeutic measures for students with dysplasia

Towards land cover map updating with ground-level panoramic photos

International audienceGeographic landscapes in all over the world may be subject to rapid changes induced, for instance, by urban, forest and agricultural evolutions. Monitoring such kind of changes is usually achieved through remote sensing. However, obtaining regular and up-to-date aerial or satellite images is found to be a high costly process, thus preventing regular updating of land cover maps. Alternatively, in this paper, we propose a low-cost solution based on the use of ground-level geo-located landscape panoramic photos providing high spatial resolution information of the scene. Such photos can be acquired from various sources: digital cameras, smartphone, or even web repositories. Furthermore, since the acquisition is performed at the ground level, the users immediate surroundings, as sensed by a devices camera, can provide information at a very high level of precision, enabling to update the land cover type of the geographic area. In the described herein method, we propose to use inverse perspective mapping (inverse warping) to transform the geo-tagged ground-level 360 • photo onto a top-down view as if it had been acquired from a nadiral aerial view. Once re-projected, the warped photo is compared to a previously acquired remotely sensed image using standard techniques such as correlation. Wide differences in orientation, resolution and geographical extent between the top-down view and the aerial image are addressed through specific processing steps (e.g., registration). Experiments on publicly available datasets made of both ground-level photos and aerial images show promising results for updating land cover maps with mobile technologies. The proposed approach contributes to the crowdsourcing efforts in geo-information processing and mapping, providing hints on the evolution of a landscape

Hypercalcemic crisis. Clinical case

Administration of calcium and vitamin D preparations always requires competent selection of doses, and combinations of drugs from a doctor as well as careful clinical and laboratory monitoring of the patient. Physician should always be aware of the danger of overdose, which can lead to very adverse consequences. An appearance of the first symptoms of overdose requires constant laboratory control and urgent measures to address this condition. One should also remember about other causes of hypercalcemia, which can help in the differential diagnosis. Clinical case presented by us is an example of how the lack of knowledge about the combined treatment of patients with postsurgical hypoparathyroidism can lead to some serious consequences such as hypercalcemic crisis

НОВЫЕ ТЕХНОЛОГИИ В ЛЕЧЕНИИ И РЕАБИЛИТАЦИИ ЗАБОЛЕВАНИЙ И ТРАВМ НЕРВНОЙ СИСТЕМЫ

Transcranial magnetic stimulation is a non-invasive technique allowing to directly stimulate the neurons of the cerebral cortex. The physiological mechanism underlying the therapeutic efficacy of transcranial magnetic stimulation is the phenomenon of long-term potentiation or long-term depression. The article presents the indications, contraindications and recommended protocols of the transcranial magnetic stimulation in certain diseases and consequences of injuries of the nervous system.Транскраниальная магнитная стимуляция - неинвазивная методика, позволяющая напрямую стимулировать нейроны коры головного мозга. Физиологический механизм, лежащий в основе терапевтической эффективности транскраниальной магнитной стимуляции, заключается в формировании феномена долговременной потенциации или долговременной депрессии. В статье рассматриваются показания, противопоказания и рекомендуемые протоколы применения транскраниальной магнитной стимуляции при отдельных заболеваниях и последствиях травм нервной системы
