Migratory erythema is the most common manifestation of the first (early) phase of Lyme borreliosis. It is defined as the spreding rash or redness at the site of the tick bite. Although the occurrence of migratory erythema indicates the presence of local infection with pathogenic strains of bacteria from Borrelia burgdorferi sensu lato complex, the exact mechanism by which spirochetes conductspreading in human skin has not been elucidated. This paper will review the literature, initially related to tick-pathogen-host interaction, after which the most common theories of the development of specific morphology of migratory erythema will be presented, as well as differential diagnostic problems that may arise from infection with other pathogens or the development of various allergic and autoimmune conditions.

Introduction The testing of stressors and the impact of stress on health and work ability of electricians working in workplaces with a special health risk is very important.

OBJECTIVE is to examine the impact of occupational stress on the ability of electricians to work.

METHODS The research was designed as a cross sectional study and covered 108 respondents, classified into two groups: electricians (52) and control group (56) made up of administrative workers. The survey included the following: Questionnaire on basic sociodemographic indicators of respondents, IRS Questionnaire, Work Ability Index (WAI) Questionnaire, General Health Questionnsire (GHQ), Copenhagen Burnout Inventory (CBI) and Occupational Stress Assessment Questionnaire. Data analysis was performed with SPSS.

RESULTS The frequency of different categories of WAI score is uniform between the tested groups (p = 0.155). Work ability is poor in 11.5%, moderate in 25%, good in 26.90% and excellent in 36.5% of electricians. The frequency of different categories of WAI score is aligned between the tested groups (p = 0.155). By analyzing all components of IRS score, it was found that there is a statistically significant difference in the components between the electricians and the  control group: requirements (p <0.001) and work role (p <0.001); GHQ is higher in electricians, but no statistically significant difference was found (p = 0.082); CBI is statistically significantly higher in electricians (p <0.001) and WAI score is statistically significantly higher in electricians (p = 0.039). In the overall population, the 10 strongest stressors were ranked and statistically significant difference in all stressors (p <0.001) between the electrician and the control group was shown. The values of the stressors are equal in relation to WAI score categories. In the electricians, the strongest stressors are: night work (4.60), hazards (4.58), shift work (4.54), working overtime (4.46), time limit for individual tasks (4.44), fear of injuries (4.42), pressure of time limits for execution of tasks (4.23), work overload (4.22), inadequate work space (4.18) and daily unforeseen situations (4.10). Average value of all stressors among electricians is 2.87 ± 1.10 (Min 1.10, Max 4.60). In the tested population, 14 different stressors have higher values than the average value of all stressors. In the control group, the average value of all stressors is 1.84 ± 0.33 (Min. 1.17, Max 2.69). Correlation analysis has shown that there is a correlation of age with shift work (r = 0.130, p = 0.013) and working overtime (r = -0.220, p <0.001). URS is statistically significantly related to the time limit for individual tasks (r = 0.149, p = 0.005) and pressure of time limits for execution of tasks (r = 0.125, p = 0.017). ERS is statistically significantly related to night work (r = 0.169, p = 0.001), shift work (r = 0.160, p = 0.002), time limit for execution of tasks (r = 0.203, p <0.001) pressure of time limits for execution of tasks (r = 0.194, p <0.001), work overload (r = 0.128, p = 0.017) and inadequate work space (r = 0.122, p = 0.022). The subjective assessment of work ability in relation to physical (p = 0.010) and psychological requirements (p <0.001) is statistically significantly lower in electricians compared to control group. DISCUSSION By analyzing all components of IRS score, it is found that there is a statistically significant difference between the electricians and the control group in the requirements and the working role components. In the overall population, the top 10 stressors were ranked and it was shown that there was a statistically significant difference in all stressors between the electricians and the control group. The average value of all stressors in the electricians is high and a large number (14) of different stressors have higher values than the average value of all the stressors. The subjective assessment of work ability in relation to physical and mental requirements is statistically significantly worse in electricians than in control group. More than half of electricians went on sick leave (mostly short leaves) during the previous year.

CONCLUSION Occupational stress significantly affects work ability of electricians. Values of WAI score are statistically significantly higher in electricians, and values of stressors are equal in relation to WAI score categories. Correlation analysis has shown there is a correlation between age, URS and ERS with individual stressors. 

Introduction: Hernia is a defect of the continuity of the normal musculoaponeurotic and fascicular abdominal wall, which allows the release of any tissue, except those that normally pass through the apertures on the abdominal wall. Aim: The aim of the paper is to show the frequency of pathological changes in the inguinal region, their timely diagnosis and treatment, in order to avoid the severe consequences of their complications. Material and methods: For this study two-year material of the Surgical Clinical Hospital Clinical Hospital Priština in Gracanica was used, where we analyzed 102 patients who were operated in this center due to pathological changes in the inguinal region. Results: Male males are represented by 91 (89.22%), and female sex with 11 (10.78%) cases. Hernia was recorded in 86 (84.31%) and testicular retention in 16 (15.69%) patients. Femoral hernia in children is extremely rare and occurs in about 0.2% of all hernias of childhood. The femoral hernias on the left with faded and gangrenous left adnex were found in a baby only three months old, where adnectomy was done. Primary hernias was 84 (97.63%) of the patients, while we recorded recurrent hernias in two (2.33%) patients. With one child, we did a recurrent retention of testicles, which was done for a year in another institution. Postoperative complications were reported in one (0.98%) patients, where there was an infection of the wound. Conclusion: In modern surgical practice, it tends to diagnose the hernia at an early stage of development, which facilitates intervention and provides a better postoperative outcome. Incarceration represents a serious complication of all hernias, so timely and accurate diagnosis is needed to take adequate surgical intervention.

Infections caused by viruses hepatitis B and C are one of the most severe problem in contemporary medicine. These viruses show high affinity to hepatocytes. The fundamental pathogenetic mechanisam which is responsible for hepatocyte damage, depends either on cytocidal effect of virus or immunological response of the infected host. The most common way of virus transmission nowdays is parenteralno, due to intravenous drug abuse, while earlier the blood transfusion was a more often the pathway of infection. Patients on chronical hemodialysis are at increased risk of HCV infection. The aim of our study was to determine the most common risk factors and pathways of HBV and HCV infection, as well as to assess the significance of the serological markers of hepatitis B and hepatitis C viruses in risk groups of patients. The study was conducted at Institute for blood transfusion at Health Center of Kosovska Mitrovica, in the period from January 2000 until December 2015. ELISA test was performed for the confirmation of presence of hepatitis B and hepatitis C viruses in the blood. The results showed that the number of respondents increased significantly during the research period. Voluntary blood donors were significantly more represented than respondents who were referred by a physician. Average age of all seropositive? examinees in the study was 47,1 ± 18,1 years (range from 8 – 79 years). HBV seropositivity was significantly more present compared to HCV seropositivity. The highest incidence of HBV and HCV infection was recorded in the working age population, between 40 and 50 years of age. Analyzing the data of the way of infection transmission, most patients reported an unknown pathway of infection (39%). The second most common way of infection transmission was hemodialysis (28.4%), while the intravenous drug abuse was noted in 13,4% of patients. We can conclude that the implementation of regular screening and timely prevention, as well as the education program of the population can be helpful in reducing the number of patients with HBV and HCV infection

Introduction: Clinical features of the ischemic neurovascular syndromes is constant and dependable from vascular territory of the affected blood vessel. Best examples are sensory and motor hemisyndromes and vision disturbances. Aim: To define motor, sensory and visual disturbances’ in patients with ischemic stroke in the border zone of the middle cerebral artery. Material and methods: Border zone ischemic stroke diagnosis was based on clinical and neurological examination and confirmed with brain computerized tomography. Estimation of the symptoms was obtained by history, and degree of functional (neurological) deficit was estimated based on NIH-NINDS scale. Results: In total 30 patients were included in the study, 12 (40%) were females 47-79 years of age (±62.3 years) and 18 (60%) males 43-79 years of age (± 58.7 years). Neurological features were clearly different based on the side of the infarct. In the group with (ACA+ACM) + (ACM+ACM) infarct localization hemiparesis is significantly more frequent. In the group with ACM+ACP infarct localization homonymous hemianopia is significantly more frequent. Initial symptom of the reversible loss of consciousness in duration of several minutes was observed in 14 (46.6%) patients. Focal seizures (clonic seizures of the face, arm and leg) were detected in 4 (13.3%) patients (all with infarcts in the anterior border zone ACA-ACM). Headache was rare manifestation seen in 5 (16.6%) patients with 4 having posterior border zone infarcts. Conclusion: Supratentorial border zone infarcts have high specificity in clinical manifestations. The implicates therapeutical approaches which are prone to specific procedures.

Introduction: The intracranial part of the optic nerve is perfused by the upper hypophyseal and ophthalmic arteries. Standard anatomical textbooks have not dealt with the vasculature of this clinicaly important part of the central nervous system. Objective: To study morphological characteristics of perioptical arterial vascularization of the intracranial part of optic nerve. Material and methods: The study was conducted on 18 whole brains of both sexes (11 male and 7 female), from the age of 51-78 years, with no signs of changes in the structures of the central nervous system. The vasculature of the optic nerves was microdissected and examined under the stereoscopic microscope after injecting their arteries with a 10% mixture of India ink and gelatin, and fixation in a 5% solution of formalin. Results: Intracranial segment of the optic nerve was richly supplied, from both, the ventral and the dorsal side, strictly with penetrating branches which come from the pial arterial network originating from the internal carotid artery and the superior hypophyseal artery for the ventral nervous surface, and from the anterior cerebral artery for the dorsal nervous surface. Conclusion: In accordance with the objective, and based on the obtained results, we confirmed that intracranial segment of the optic nerve has a rich and very delicate vascular network.

Introduction: During the course and development of diverse cardiological diseases different central nervous system complications may develop. These are most frequently related to the nature of the cardiovascular entity itself. Aim: To evaluate the association between atherogenesis factors and border zones strokes within the cerebral medial artery vascularization territories. Methods: In total 30 patients were enrolled in the study. Stroke diagnosis was based according to clinical and neurological examination and brain CT findings. The study analyzed risk factors correspondingly to World Health Organization criteria. Results: In majority of patients (18; 60%) arterial hypertension was diagnosed. Additionally, following condition and risk factors were identified: cardiological diseases (17; 23.3%), cigarette smoking (13, 43.3%), hypercholeterolaemia (9; 30%) and diabetes (7; 23.3%). In the group with cardiological diseases most frequent was myocardial infarction (9; 56.2%), AV block II and III (5, 29.4%), atrial fibrillation with slow ventricular response (3; 17.6%). Conclusion: Results of the study point to conclusion that myocardial infarction, AV block II and III, atrial fibrillation with slow ventricular response, iatrogenic hypertension and traditional risk factors for atherogenesis significantly influences presentation of the border zone strokes within the cerebral medial artery vascularization territories.

Newly synthetized derivative of bile acid, sodium salt of 3α, 7α-dihydroxy-12-oxo 5β cholanic acid (monoketocholanate) expressed a good characteristic as intranasal transport enhancer of xenobiotics.The aim of our sudy was to explore if it has an influence on bile metabolism and to measure its concentration in blood and bile after intravenous and intranasal administration. The experiment was performed in vivo on adult male Wistar rats. The determination of monoketocholanate (MKCh) in rats blood and bile, was carried out by high-performance liquid chromatography (HPLC), on an HP ODS2 column, using methanol/acetonitrile/acetate buffer as mobile phase. Absorbances were measured at 210 nm.Blood samples were taken from the prepared right axillary artery in 0, 1, 5, 10, 20, 30, 60, 90, 120 and 180 minutes from the beginning of the experiment. Bile was collected in a half an hour intervals,during the three hour period. The results showed that MKCh changed the amount of excreted bile depending on the way of application. Intranasal application increased the bile volume and the MKCh concentration, both in blood and bile compared to the intravenous application (p<0.05). Distributionm of MKCh through animal organism depends on the way of application of the substance, which probably determines its caracterisation as the transport promotor of applied xenobiotics. HPLC has proved as aa relatively simple, fast and effective method for the determination of synthetic bile acid,MKCh in these biological materials.

Introduction. Radius fracture at typical site - fractura radii loco typico, is one of the most common fractures (more than 10% of all fractures). It is frequent in the fall on the palm of the hand. It happens at all ages. Objective. To examine the efficacy of electromagnetotherapy in the treatment of patients with radius fracture at typical site in order to reduce pain, swelling and increased mobility of injured tissue and reduce the possibility of complications. Material and methods. The study includes 100 patients with radius fracture at the typical site of which 55 women and 45 men, aged 20 to 70 years. The study included patients undergoing bone trauma treated conservatively by plaster immobilization, immediately after orthopedic treatment patients were treated with lowfrequency pulsed electrical magnetic fields produced by the machine MAGNEMED MT - 91 results. Pain in the wrist after physiotherapy treatment static isometric contractions and after the application of electromagnetic therapy was significantly more intense in the control group. Swelling in the wrist were significantly reduced in patients treated with electromagnetic fields. In all patients, after 20 applied electromagnetic field therapy achieved a significant increase in flexor and extensor muscle strength. Electromagnetotherapy is important in the prevention of complex regional pain syndrome.

Introduction: The presence of malignant altered axillary lymph nodes, and their timely detection is crucial for staging and prognosis of breast cancer. Echotomographic examinations are widely used technique, and represents one of the first tests of diagnostic modalities. Classic B mode, Doppler sonography, and MicroPure testing technique, allow a comprehensive assessment of the detailed morphology and internal structure of the nodes (number, location, size, shape, borders, echogenicity, edema of the surrounding soft-tissue, the presence of microcalcifications), and determination of their nature. Objective:The aim is to determine the role of echotomographic review the morphology, determining the nature and setting guidelines for diagnostic testing algorithm for malignant altered axillary lymph nodes. Materials and methods: This cross-sectional study included 212 echotomographic tested axillary lymph nodes in the Department of Radiological Diagnostics KBC "Dr Dragisa Mišović-Dedinje" in Belgrade, in the period from February 2016.do March 2017. All patients were examined in the supine position with arms in abduction, and external rotation. The following parameters: shape, size, and homogeneity of the echo-structure, edge, an auxiliary structures such as intranodal necrosis, edema and peripheral vascularization, as well as the presence of microcalcifications, using classical B mode, Doppler sonography and MicroPure technique. For all examinations we used Toshiba device, Aplio XG, 10MHz linear transducer. Results: Of a total of 212 tested nodule, histopathology was also verified 44 malignantly changed (21%), 4 of which the primary (9%) in a patient with Hodgkin's lymphoma, and secondary 40 (91%) in patients with breast cancer. Other nodes 168 (79%) were normal-reactive. The best performance in the echotomographic examinations are the criteria of: the shape (longitudinal cross-ratio <2) with a sensitivity of 86.9%, presence of microcalcifications with sensitivity of 83,7%, hilus (not clearly defined, and hypoechogenic) with sensitivity of 81.8%, the size (transverse diameter greater than 8mm), with a sensitivity of 79.2%, as well as echogenicity (hypo to anechogenic) with sensitivity of 73.1%. Conclusion: Echotomographic review is a useful imaging modality in evaluating the morphology and nature of axillary lymph nodes, but none echotomographic criterion in itself is not enough reliable in evaluating malignancy. Meticulousness when reviewing and examining all the criteria and modalities (B mode, Doppler, MicroPure) remain imperative in the diagnostic algorithm of tests axillary lymph nodes.
