Introduction. Pathology of the inferior turbinates (IT) was found in 76.1% of patients with difficulty in nasal breathing. If nasal breathing cannot be restored with conservative measures, surgical intervention becomes the method of choice.Materials and methods. Under local infiltration anesthesia, the IT is fractured and retracted medially (medialization). In the anterior section of the HHP, a vertical incision 0.5 cm long to the bone is made, through which the mucosa is peeled off from the bone base of the concha with a raspator-suction and a small tunnel from 2 to 3 cm long is created. shell surfaces and a small area of the mucosa of the lateral surface of the IT and the lateral wall of the nasal cavity. After insertion into the created tunnel of the required size of the "spreader-implant" plate, treated with a thin layer of LTK glue, the shell is slightly pressed with a self-inflating latex-foam rubber swab introduced into the IT for 10–15 minutes. At the end of the operation, after removing the tampon, the edges of the incision are processed with LTK glue.Results. The results of the study demonstrate the effectiveness of the developed method for the rapid restoration of nasal breathing after rhinosurgical interventions. We use this technique in the overwhelming majority of cases of fibrous and bone forms of IT hypertrophy. In cases of the cavernous form, we perform a submucous conchotomy with a shaver, which makes it possible to very accurately remove exactly that part of the concha that violates the patency of the nasal cavity. In all cases, we consider it compulsory to carry out the IT lateroposition according to our method, which significantly improves the result of the operation. The surface of the shell remains completely covered with mucosa and as a result of matching the edges of the incision, the wound surface is absent. At the same time, after the operation, the shell remains full anatomically and functionally, i.e. consists of the bone skeleton and the corresponding volume of soft tissues.Conclusion. The question of how to predict in the long-term postoperative period the normal size of the modeled IT, apparently, is currently not answered even by highly qualified rhinosurgeons. In this regard, there remains a need to search for new technologies for treating patients with chronic hypertrophic rhinitis.

Topicality: The result of surgical treatment depends largely on the chosen method of management of the postoperative period, the main purpose of which is to reduce the effects of surgical trauma. Despite the wide variety of drugs for local and systemic use, the question of pharmacotherapy of the operated sinus remains open to this day. The main properties that a modern drug should possess are safety and high clinical efficacy. Aim: to study the clinical efficacy of topical application of a complex preparation based on a saline solution containing sodium hyaluronate and dexpanthenol in patients with chronic sinusitis after functional endoscopic sinus surgery (FESS). Materials and Methods: Clinical and laboratory studies were conducted on 47 patients with chronic rhinosinusitis who underwent surgery using the FESS technique. Patients were divided into 2 groups according to the principle of the postoperative period. Patients of research group (n=21), except for traditional therapy, was used locally NASOMER (a preparation based on a water-salt solution containing sodium hyaluronate and dexpanthenol); to the control group (n=26) patients entered, in the postoperative period received traditional therapy. Traditional therapy included a toilet of the nasal cavity, the use of short-course topical decongestants, irrigation of the nasal cavity with water-salt solutions. Criteria of clinical effectiveness: data of endoscopy of the nasal cavity, rhinomanometry, activity of the mucociliary transport system. The effectiveness of functional research methods in the postoperative period was determined on the 7th and 14th day of treatment. Results: On the 3rd day of the study, an increase in the swelling of the nasal cavity was observed in patients of both clinical groups, correlated with difficulty in nasal breathing. On the 7th day, a decrease in edema was observed in patients of both groups, but in the experimental group, the index of nasal breathing, according to rhinomanometry, was significantly (p<0.05) different from the control group, and was respectively 1.54±0.14 and 2.04±0.19 kPa/l*s. On the 14th day of the study, no significant difference was observed between these indicators. When studying the activity of the ciliated epithelium of the mucous membrane of the nasal cavity, it was proved that patients of the experimental group on day 7 after surgery showed a statistically significant difference in this indicator compared to the control group (17.8±1.0 and 22.7±2.1 min. respectively). Conclusions: The use of NASOMER after surgical intervention in patients with chronic rhinosinusitis contributes to more effective treatment compared with traditional therapy, as evidenced by the rapid recovery of the main functional parameters according to active posterior rhinomanometry and mucociliary clearance. Based on the results of the studies performed, the use of NASOMER for pharmacotherapy in the postoperative period is recommended for patients who have undergone rhinosurgical interventions with the aim of reducing the period of postoperative rehabilitation as an effective anti-inflammatory and wound-healing agent.

Minimal Invasiveness

Relevance: Modern endonasal surgery allows to remove polyps from all affected paranasal sinuses, following the principles of minimal invasiveness. Minimal traumatic of surgical intervention gives the best results, accompanied by less progression of the disease. Minimal invasiveness of surgical intervention and its obligatory combination with postoperative medical treatment are common practice in many countries. One of the drugs that actively effect the restoration of the mucous membrane of the nasal cavity and paranasal sinuses in the early postoperative period is Nazomer, which includes sodium hyaluronate and dexpanthenol in saline solution. The purpose of the study is to investigate the effectiveness of the drug Nazomer in patients with polyposis rhinosinusitis after endoscopic polyposynosotomy. Results and discussion: The main group consisted of 30 patients with polyposis rhinosinusitis, who were prescribed Nasomer in addition to standard treatment in the postoperative period. The control group included 30 patients who underwent standard treatment in the postoperative period. As criteria for clinical efficacy, data from endoscopic examination of the nasal cavity and indicators of anterior rhinomatometry, measured by the «Optimus» device, were selected. In the main group, the index of nasal breathing according to rhinomatometry was better than the results of patients in the control group on the 3rd and 5th day of the postoperative period by 26% and 24%, respectively. Conclusion: The use of the drug Nazomer in the postoperative period in patients with polyposis rhinosinusitis contributes to more active restoration of respiratory function of the nasal cavity compared with the control group, according to rhinomatometry, up to 26%. Based on the results obtained, the drug Nazomer is an effective anti-inflammatory and regenerative agent in the postoperative period in patients with polyposis rhinosinusitis.

The article describes the possible impact of modern technological changes (disruptive technologies, digitalization, and automation) on regional development in Russia based on the patterns of geography of innovations and previous trends. The rates of non-resource growth over the past twenty years have been higher in those regions where inventive activity, intensity of R&D expenditures, share of researchers and employees with higher education were higher, but the same relationship cannot be traced with the intensity of the use of advanced production technologies (automation) and the availability of the Internet. During the declared pandemic in Russia in 2020, patent activity in the vast majority of regions decreased, the processes of production automation slowed down, but digitalization accelerated in terms of internet access and the development of online commerce. The creation of disruptive technologies is still concentrated in large cities and super-regions due to agglomeration effects, knowledge spillovers and concentration of human capital. But the effects of their introduction and distribution can be differentiated. In the leading regions with high proportion of creative professionals and entrepreneurs, development may accelerate, in old industrial regions, automation will increase the risks of temporary unemployment and inequality. For the least developed territories, the lack of digitalization potential and lack of highly qualified personnel may further worsen the situation.

The Impact

In the recent years, the world economy has undergone an enormous transformation. It can be noted that it is not only based on industry, but also on knowledge. Achieving a competitive advantage by regions is further focused on investing in fixed assets, but, what is also important, in human capital. At present, a factor that is increasingly important in achieving competitiveness is the ability to use intangible resources. Expenditures on education and research, investing in people, their knowledge and skills are an essential precondition of raising competitiveness. In the case of a highly qualified staff, it allows the efficient introduction of new technologies and the creation of new directions for its development. The competitiveness of the regions is influenced, inter alia, by human talents, knowledge, entrepreneurship, initiative and own resources to improve living conditions. Human capital is thus a key determinant of the competitiveness of regions in Poland. Therefore, the priority of this article is to analyze the impact of selected components of human capital on the competitiveness of regions in Poland in the years 2007-2014. The article is both theoretical and empirical. The first part reviews the literature closely related to the topic of the work. The second part includes a statistical analysis and a construction of a panel model estimated by the method of least squares. GRETL program was used for calculations. Imię autora*:

Category: Hindfoot, Trauma Introduction/Purpose: The axial alignment of the calcaneus has paramount importance in the management of these fractures. The Harris view has long stood as the recommended radiograph to assess axial alignment. However, given the obliquity at which the radiograph is obtained, it doesn´t represent a true axial view and is subject to inaccuracies secondary to rotational malpositioning of the foot and mismeasurement of angulation. Multiple reports have described the axial alignment as a surgical outcome, but usually this assessment of the residual deformity have no described method. The objectives of this study are to evaluate the capacity of Harris view to assess axial alignment in a cadaveric model and to describe the use of a true AP view of the calcaneus that we have named Captain´s view. Methods: Five below knee amputated fresh-frozen cadaveric specimens were used in the study. For each specimen, the soft tissues over the lateral side were removed to access to the lateral wall. A small wedge of the cuboid was removed to visualize the center of the calcaneocuboid articular surface. LCA-guide and a cannulated drill were used to create a tunnel in the axis of the calcaneus. An oblique osteotomy was performed in order to simulate a non-comminuted fracture. Varus deformity was created by inserting solid radiolucent wedges into the osteotomy to create models of 10, 20, and 30 degrees of varus angulation. Harris and Captain views were obtained for each specimen with 0 (control), 10, 20, and 30 degrees of varus malalignment. Measurements of the deformity were made digitally on each fluoroscopic image. Results: The average degrees of varus in Harris views were 10,9 (5,5-16); 11,5 (8,2-13,6); and 18,3 (13,3-23,6) for 10,20 and 30 degrees of deformity respectively. The average degrees of varus in Captain´s view were 13,0 (7,3-20,9); 18,4 (11,7-23,5); and 28,2 (24,4-31,1) for 10,20 and 30 degrees of deformity respectively. The average degrees of error for varus deformity in Harris views were 4,1 (41%); 8,4 (42%) and 11,6 (39%) for 10,20 and 30 degrees of deformity respectively. The average degrees of error for varus deformity in Captain´s views were 4,8 (48%); 3,6 (18%) and 2,8 (8%) for 10,20 and 30 degrees of deformity respectively. Conclusion: The results of this study show a high rate of mismeasurement for both radiographic views. Despite the average angles have a clear correlation with the severity of varus, the wide range of error observed between specimens make this assessment unreliable and inaccurate. We observed an improvement of accuracy of captain´s view for more severe deformities, but not with Harris views which maintain a 40% mismeasurement in all the settings. Therefore, intraoperative Harris views should not be used in isolation to evaluate axial alignment and Captain´s view provides an additional perspective that can be useful to rule out severe deformities.
