Background. The long term management of miniplate fixation osteosynthesis remains debatable and controversial with few authors advocating routine removal of the miniplates after 3-6 months of placement, while others recommend retention of the miniplates unless their removal is clinically indicated. Objective. The aim was to study the incidence, indications, time gap, role of metallic composition and site of removal of miniplates in operated cases of maxillofacial region over a two-year period. Methods. Patients undergoing removal of miniplates over 2-year period were studied and evaluated regarding the number of miniplates removed, time gap present between fixation and removal of miniplates, indications for removal, metallic composition of miniplates removed, sites of removal and complications. Correlations between indications for miniplate removal based upon time gap, metallic composition, age group and number of miniplates present were determined using Chi-square test. Correlation between metallic composition of miniplate and time gap was also determined using Chi-square test. Results. The miniplates were removed in 20 patients (16 males and 4 females). Most common indication for removal was infection (45%). Forty-five percent of the patients underwent miniplate removal within 1 year of placement. Thirty-four miniplates and 118 screws were removed. The correlation between indications for miniplate removal and time gap was found to be statistically significant (P = 0.04). Conclusion. Most of the hardware removal is performed subsequent to complications associated with hardware and local factors play more important role than metallic composition. Routine asymptomatic miniplates do not require removal and is not recommended.

Aim– to elucidate the role of antiepileptic pharmacotherapy in pathomorphosis of focal epilepsy in adult patients.Materials and methods. We examined 91 patients with focal epilepsy (main group, G); among them, 37 (41%) men (M) and 54 (59%) women (W). At the time of the first visit, 82 (90%) of  them [33 (89%) M and 49 (91%) W] were under antiepileptic therapy. The age of patients ranged  from 18 to 78 years (average 37.5 years). The debut of epilepsy was observed at the ages from 4  to 71 years. The duration of the disease ranged from 1 to 52 years, with the average of 16.1 years. All patients were then followed up for 1 to 2.5 years. Clinical and neurological examinations were  conducted in all patients; laboratory and instrumental diagnostic tests were used if indicated. The  medical history of patients was analyzed from the onset of epilepsy; if needed, new therapies were  prescribed or the existing therapies were modified. The therapeutic efficacy was assessed  using the data from the daily-seizures diary. The differences between the groups were tested for  their significance using the Chi-square test or the exact Fisher test if there were less than five  observations in the group. Results.Only 47 (52%) patients of group G [21 (57%) M and 26 (48%) W] received an antiepileptic therapy from the debut of the disease; the therapy was then adjusted in 41 (45%)  cases [19 (51%) M and 22 (41%) W (р>0.05)]. Of the 82 patients receiving therapy at the time of  examination, 37 (45%) received the basic, 20 (24%) – the updated, and 24 (29%) – a  combination of the basic and updated AED; in about 2% of cases, a combination with the 1st  generation drugs was prescribed. Monotherapy was used in 45 (55%), and polytherapy – in 37  (45%) patients. Of the 19 patients taking KBZ as the starting monotherapy, 10 (52%) received the drug in the non-prolonged form, twice a day. Relapse after long-term remission (12 months or  more) in 80% of cases was associated with changes in the AED regimen. Side effects were  observed in 43 (52%) patients under the treatment [15 (45%) M and 28 (57%) W]. Among those,  who underwent MRI examination, structural epileptogenic changes were detected in 37 (54%)  patients [21 (72%) M and 16 (40%) W (p<0.05)]. Comorbidity and the associated co-therapy were detected in 88% M and 90% W who were >50 years old.Conclusion. Antiepileptic pharmacotherapy is a leading factor that induces evolutionary changes in the clinical and neurophysiological picture of epilepsy. With a timely and rational approach, the  use of AED allows for creating favorable development of pathomorphosis of the disease. Full  patients awareness of the AED therapeutic regimens and the associated risks may increases the  compliance, reduce the risk of decompensation and improve the prognosis of epilepsy.

Abstract Background: To explore the role of bevacizumab (BV) in High-grade Meningiomas (HGMs) undergoing surgical treatment.Methods: Review the clinical data of 139 patients with HGMs and divide them into BV group and non- BV group according to whether they receive BV treatment. Then we compared the progression-free survival (PFS) and overall survival (OS) of the two groups.Results: The Chi-square test showed significant differences between the BV group and the non-BV group in terms of 12-month PFS (PFS-12), 36-month PFS (PFS-36), median PFS (M-PFS), 12-month OS (OS-12), 36-month OS (OS-36), and median OS (M-OS). However, there was no statistical difference between the BV group and the non-BV group in terms of 6-month PFS (PFS-6), 60-month PFS (PFS-60), and 60-month OS (OS-60). The log-rank test indicated significant differences in PFS and OS between the BV group and the non-BV group.Conclusion: The role of BV in patients with HGMs is to relieve the symptoms of peritumoral brain edema (PTBE) and prolong PFS and OS. However, whether increasing the dose of BV after surgery can improve the long-term PFS and OS of patients with HGMs needs further research.

Abstract Background Human papillomavirus (HPV) type 16 accounts for a larger share of cervical cancer and has been a major health problem worldwide for decades. The progression of initial infection to cervical cancer has been linked to viral sequence properties; however, the role of HPV16 variants in the risk of cervical carcinogenesis, especially with longitudinal follow-up, is not fully understood in China. Methods We aimed to investigate the genetic variability of HPV16 E6 and E7 oncogenes in isolates from cervical exfoliated cells. Between December 2012 and December 2014, a total of 310 single HPV16-positive samples were selected from women living in the Taizhou area, China. Sequences of all E6 and E7 oncogenes were analysed by PCR-sequencing assay. Detailed sequence comparison, genetic heterogeneity analyses and maximum-likelihood phylogenetic tree construction were performed with BioEdit Sequence Alignment Editor and MEGA X software. Data for cytology tests and histological diagnoses were obtained from our Taizhou Area Study with longitudinal follow-up for at least 5 years. The relationship between HPV16 variants and cervical carcinogenesis risk was analysed by the chi-square test or Fisher’s exact test. Results In this study, we obtained 64 distinct variation patterns with the accession GenBank numbers MT681266-MT681329. Phylogenetic analysis revealed that 98.3% of HPV16 variants belong to lineage A, in which the A4 (Asian) sublineage was dominant (64.8%), followed by A2 (12.1%), A1 (11.4%), and A3 (10.0%). The A4 (Asian) sublineage had a higher risk of CIN2+ than the A1–3 (European) sublineages (OR = 2.69, 95% CI = 1.04–6.97, P < 0.05). Furthermore, nucleotide variation in HPV16 E6 T178G is associated with the development of cervical cancer. Conclusion These data could provide novel insights into the role of HPV16 variants in cervical carcinogenesis risk in China.

Although the issue of corporate culture has been taken over and addressed in the literature from various perspectives, there are very few researchers about the role of leadership and motivation in it, respectively very few researchers have addressed them as important components of the international company’s corporate culture. The present paper aims to point out that leadership and motivation can be perceived as important aspects of the international company’s corporate culture. The object of the investigation was an international company (situated in Italy) and its five subsidiaries (situated in Italy, Czech Republic, Germany, and Turkey). As the main research method, there was chosen the method of the questionnaire survey, which was attempted by all the company’s employees (totally 270 respondents). The questionnaire was divided into three separate, but logically related parts—leadership, motivation, and corporate culture, and submitted to two groups of respondents—the company’s management and its employees. In total 11 hypotheses were formulated and further evaluated by the methods of Pearson Chi-square Test, Fisher’s Exact Test, Cramer’s V coefficient, Kendall rank correlation coefficient, Eta coefficient, Spearman coefficient, Mann–Whitney U test and Wilcoxon W statistics, Kruskal–Wallis test, and Friedman’s test. The results of the research have proven that leadership and motivation are important parts of the corporate culture.

Abstract The author seeks an answer to the question whether a higher intensity of tourism movement is connected with a higher share of tourism in the economy in selected tropical island territories. With the use of the Spearman correlation coefficient, the existence of the average positive correlation between the intensity of tourism movement and the share of tourism in the economy has been determined. In the second part of paper, the author looks at the conditions which affect the role of tourism in the economy in proportion to the intensity of tourism movement. For this purpose, the Chi-square test and detailed case studies of chosen tropical islands are discussed.
