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: Radiological diagnostics is the dominant diagnostic discipline in medicine. The level of technical equipment of radiological departments directly affects many aspects of importance for the diagnosis of a large number of pathological conditions and, therefore, the progress in the treatment of patients. Aim: The research analyzes the existing situation in radiological cabinets on the territory of AP Kosovo and Metohija. Particularly important elements will be analyzed for the functioning of the radiology service. An analysis of the obtained results gives recommendations in order to improve radiological diagnostics. Metods: A survey was conducted to obtain relevant data. A questionnaire consisting of segments containing basic elements for determining patients' accessibility criteria, equipping the cabinet with equipment and employing professional staff was designed. This formulated questionnaire was sent to radiological departments in health institutions on the territory of AP of Kosovo and Metohija, which are part of the Ministry of Health of the Republic of Serbia. Results: The highest percentage of radiological equipment is represented in KBC Kos. Mitrovica and KBC Pristina-Gračanica, a total of 54%. The percentage of medical staff is at KBC Kos Mitrovica radiologist 50%, work technician 36%. This is followed by KBC Prishtina-Gračanica with 25% radiologists and 27% of radiological therapists. Conclusion: The basics of radiological diagnosis are conventional x-ray techniques. Tertiary health care does not adequately possess radiological high-tech modes of computerized tomography and magnetic resonance. Staff training is required in order to re-establish existing knowledge and skills development that are followed by the continuous professional development of technology applied in radiological practice.

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.

Introduction: Solar or artificial UVA radiation play a major role in photoaging of the skin. Objective: The aim of our study was to determine the presence of morphological changes in the dermis of mouse skin exposed to UVA radiation, with or without the usage of photoprotective cream. Methods: This experiment involved the exposure of female BALBc mice, to solarium UVA lamps. The animals were divided into 2 experimental and 2 control groups. Before the radiation exposure, the hair on the backs of the experimental animals and one kontrol group was removed by shaving 3 times a week, and a half an hour before the exposure a broad spectrum photoprotective cream (UVA filter and SPF 50) was applied on half of the experimental animals. The animals were exposed to radiation 5 times a week, 2 hours a day (the dosage of 156 J/ cm2), for 16 weeks, up to a total radiation of 12500 J/cm2. Results: The presence of impaired collagen fibril network was the most pronounced in the experimental group of animals exposed to radiation without the usage of photoprotective cream (p<0.001). The presence of normal collagen fibril network was observed in the both control groups (p<0.001). The presence of incipient solar elastosis was observed in the experimental group of animals exposed to radiation without the usage of photoprotective cream. Conclusions: The results showed that the usage of a photoprotective cream provided an efficient protection against the effects of UVA radiation and dermal photoaging.

Introduction: Age-related cataract (senile cataract) is one of the leading causes of preventable blindness in the world. Objective: To determine whether other ocular comorbidities (glaucoma, age related macular degeneration, diabetic retinopathy) affect visual function and quality of life in cataract and pseudophakic patients, and, if possible, to determine which disease has a significant effect. Methods: In this study 202 patients were examinated, regarding of the status of cataract on the second, following eye; the patients were divided into two groups: cataract and pseudophakia. Results: Patients with myopia and capsular glaucoma had significant improvement in average visual acuity (0.87 vs. 0.65) after surgery compared to preoperative results (0.38vs.0.24) (p<0.01). Also, patients with age related macular degeneration and non-proliferative diabetic retinopathy with an average preoperative visual acuity (0.05 vs. 0.05) after surgery have a significant improvement in average visual acuity (0.2 vs.0.2) (p<0.01). Patients with primary open-angle glaucoma have significant improvement in average postoperative visual acuity (0.28) compared to the preoperative results (0.05) (p<0.01), while patients with primary angle closure glaucoma had improvement in postoperative average visual acuity (0.1) compared to the preoperative results (0.05) (p<0.1). Conclusion: Significant improvements in postoperative average visual acuity compared to preoperative results reduce difficulties in vision-related activities thus providing higher quality of life.

Introduction: Hepatitis B virus is primarily hepatotropic, causing chronic hepatitis B in 5-10% of patients. Chronic hepatitis B (CHB) infection is a dynamic process, which may have five phases: immunotolerant, immunoactive, latency phase, reactive and HBsAg negative phase. Aim: Analyze clinical and biochemical parameters in relation to morphological condition of the liver. Material and Methods: The study enrolled 35 patients diagnosed with CHB, 24 males and 11 females, aged between 12 and 62 years, in the period 2015-2016. The diagnosis was based on serological, biochemical results, and liver biopsy. In patients in an ELISA assay demonstrated the presence of HBsAg in serum. Results: The study shows that middle-aged male patients are more prone to chronic hepatitis B infection. Most patients have one or two symptoms.Fatigue and right subcostal pain are most commonly present in the groups with fibrosis in second- and third-degree,and hepatomegaly in the group with fibrosis in first-degree. Splenomegaly is present only in groups with fibrosis in third and fourth degree. Elevated average aminotransaminase levels reflected the degree of fibrosis. Significant statistical difference in aminitransaminase levels was confirmed between the group of patients with third- and forth-degree and patients without fibrosis. Conclusion: The increase in ALT levels reflect the degree of fibrosis and cirrhosis of the occurrence. ALT levels may be a predictor of the process of the fibrogenesis, as well as to indicate the degree of fibrosis in HHB infection. Due to frequent discrepancies between clinical manifestations and results of laboratory tests, liver biopsy has been considered “gold standard” for establishing the diagnosis, staging chronic hepatitis B, making therapeutic decisions, monitoring the course of the disease, and assessing prognosis.

Introduction. The incidence of both non-melanoma (NMSC) has been increasing over the past decades worldwide. The objective of the paper was to determine incidence trend of NMSC in the Serbian population on the territory of Kosovo and Metohija in the period 2004-2013. Method. Descriptive epidemiological study was done. Data about incidence for NMSC were obtained from the record. Data about population originated from International Red Cross and UMNIK. Crude incidence rates were calculated per 100 000 inhabitans. Trend lines were estimated using linear regression. Results. During a 10-year period a total number of new NMSC cases was 304 (173(56,9%) in men and 131(43,1%) in women). Аverage crude annual incidence rate was 29,08/100 000. A significantly increasing incidence trend for NMSC in men (y=0,617x+24,29, R2=0,500) was determined. Conclusion. Our findings showed significantly increasing incidence trend of NMSC. Presented findings support the important role of primary prevention and early detection of NMSC in the earliest age. Screening of skin cancers may improve treatment and prognosis by earlier diagnosis.
