The belief in the inability of neurogenesis, that is the inability to create new neurons after embryonic and early postnatal development of the central nervous system, was rejected in the mid-nineties, when the existence of neurogenesis in restricted areas of CNS adult mammals, including humans, was discovered.Transplantation of stem cells or their derivatives into respective tissues or organs is considered as one of the most promising remedies for many incurable diseases.In this review, we summarized current knowledge and present and future perspectives andchallenges regarding stem cells treatment for Parkinson's and Alzheimer's disease, as the most common age-related neurodegenerative diseases.

Disturbances of thyroid function are often accompanied by cognitive and affective disorders. Assessment of cognitive status in the patients with subclinical hypothyroidism represents a possibility for early diagnostics of cognitive impairment and timely introduction of necessary pharmacotherapy treatment. The aim of this study was to quantify whether there are P3 event related potential (ERP) deviations as electrophysiological markers of cognitive activity in patients with subclinical hypothyroidism. P300 potentials were examined in thirty patients with subclinical hypothyroidism and in 30 healthy subjects of the control group. P300 was recorded using the classic auditory oddball paradigm, with 20% of target and 80% of non-target stimuli. The results analysis showed a significantly longer latency P300 and reduced amplitude P300 in subjects with subclinical hypothyroidism compared to euthyroid subjects. There is also a statistically significant negative correlation between the results of a mini mental state examination and the P300 latency at Fz electrode (r= -0.47, p <0.01) and Cz electrode (r= -0.43, p =0.017). P300 ERP is important in the evaluation of patients with subclinical hypothyroidism, due to the sensitivity in the detection cognitive disorders.

Due to the extension of life expectancy, the number of elderly people increases, and thus the number of disease and injuries of the locomotor system, especially the hip joint. One of the persistent trend is an increasing trend in the number of patients with coxarthrosis and implanted total hip endoprosthesis. One of the postoperative complications that occurred after implantation a total hip endoprosthesis is heterotopic ossification (HO). HO is the most common complication that occurs after the implantation a total hip endoprosthesis with recorded cases in the range of 9-90%. HO are insufficiently understood phenomenon, which is characterized by the formation of bone in periarticular tissues. We prospectively followed patients who implanted total hip endoprostheses in the department of orthopedics ZC in Kos. Mitrovica in 2008. and 2009. year. We examined the influence of physical agents on the prevention of HO near the hip joint. In these patients the treatment was carried out kinesiotherapeutic at the Center for Rehabilitation Health Center Kosovska Mitrovica, as well as pulse therapy low frequency magnetic field frequency of 30 Hz, 30 minutes, 8 mT intensity and 15 minutes interferential current, 0-100 Hz frequency. All patients were on the rehabilitation of one month (20 days). Based on this research we confirmed the assumption that the use of low frequency pulsed magnetic fields, interference currents and kinesitherapy prevents HO in patients after implantation of total endoprosthesis of the hip joint.

Oral health is an integral part of the general health of humans and significantly affect the quality of life. Dental caries is today the most widespread disease of our civilization, which if untreated leads to tooth loss. It is significant to note that studies show the possibility of successful prevention of diseases of the oral cavity. Traditionally, there has always been lower economic and educational level of the population in rural areas, and also a lower availability of dental services. Possible reasons for this include the lack of pediatric dental offices in schools in rural areas, the greater the distance of the dentist, the lack of properly organized school dental care, lack of knowledge about the importance of oral health by their parents as role models and unfavorable socio-economic status. The aim of this study was to examine the level of awareness and habits of children and parents toward oral hygiene and bad habits in the Serbian enclaves in Kosovo and Metohija and to compare them with children who live in urban areas in Kosovska Mitrovica. The study included 160 elementary school students in the area of Kosovska Mitrovica (urban area) and the Serbian enclaves on Kosovo and Metohia (rural area) which included elementary school students from Sirinić District, the Kosovo Morava, the central Kosovo, villages of Suvo Grlo and Banja in municipality Istok. By examining the frequency of tooth brushing we found that 32 (40%) of children in enclaves brush their teeth once a day, 40 (50%) two times a day, and only 8 (5%) of them maintain hygiene teeth 3 times a day. Boys who wash their teeth three times a day were 12.5% and 37.5% of girls. The children from the enclave more often come to the dentist when they have an appointment (33:8), while children from Kosovska Mitrovica more often come to the quarterly control (21:4). An interesting fact is that 15.33% of children from urban areas cited as a source of oral health information from the Internet and Android application for mobile phone or tablet. The difficult security situation, limited freedom of movement, the poorly developed dental services, poor health education and promotion of oral health of the population of Serbian enclaves, the reason for the weaker informing children and parents about preventive dental measures. It is necessary to mobilize all sectors of society on joint actions aimed at the promotion of oral health.

Diabetes mellitus is one of the most common non-communicable chronic diseases, which is the combined action of genetic factors, environmental factors and lifestyle. Specific conditions occur in the oral cavity in the course of diabetes that cause changes in all oral tissues with different symptoms and signs. Increased salivary glucose level is followed by increased accumulation of dental plaque and decreased resistance to noxious agents. The most common oral manifestations in diabetic patients include higher prevalence of periodontal desease, burning mouth syndrome, disruption in salivary flow, opportunistic infections, higher prevalence of denture stomatitis, oral lichen planus, fissured tongue, angular cheilitis etc. Dental interventions in patients with well-controlled diabetes are not different from those applied to nondiabetic patients. Regular monitoring of these patients is required because of the complications that can occur.

Modern aspects of social development brings new concerns that contribute to obesity, as a direct result of the overall abundance. Almost that there is declarative consistent view that obesity, according to its frequency, a global epidemic of the new millennium and that is because of the effect on the overall health of the necessary complementary multidisciplinary approach, because its prevention can prevent and significantly reduce the mortality rate. Technological development, automation in the food production, reduced participation of manual labor and a sedentary lifestyle, obesity causes an increase not only in highly industrialized, but in the less developed countries. Obesity is a direct temptations of modern civilization and a major challenge for a community where food is plentiful. This fact increases the responsibility of each individual and placed before him the obligation to recognize the causes of obesity, so that, by changing their behavior, could reduce the burden involved with obesity.

The most important adipocytokines affecting the formation and the regression of atheromas plaque in the coronary blood vessels are adiponectin and resistin. The essence of this test is to determine the correlation of the leading biochemical parameters of atherosclerosis, adiponectin and resistin and determine their interdependence with other biochemical parameters in patients with diabetes mellitus and coronary heart disease. Our study group consisted of 140 patients and 40 control group (healthy), 50 with diabetes mellitus and 50 with coronary heart disease (myocardial infarction and angina pectoris). We find that the average value of adiponectin in the group with type 2 diabetes mellitus were significantly lower than in the control group (4.38 to 6.74, p = 0.001, p <0.05). In the same study group average value of resistin was significantly higher than in the control group (15.8 to 7.88, p <0.001). The average value of adiponectin and resistin in patients with myocardial infarction and angina pectoris are no different from the value obtained in diabetes mellitus (4.94 to 4.38 and p = 0.397, p> 0.05). In the same study group average value of resistin was significantly higher than in the control group (15.73 to 7.88, p = 0.001, p <0.01) and not different than in the group with diabetes mellitus. Values Pearsonovg correlation coefficient shows that the biggest falls inversely proportional dependence of adiponectin with a simultaneous increase in resistin is expressed in patients with myocardial infarction, which is expressed very good correlation coefficient (-0.36). In all the groups, shows that there is a negative correlation between resistin and adiponectin, with increasing values of resistin values of adiponectin are reduced.

Collagen is a major constituent of the gingival extracellular matrix, which crucially affects the histoarchitecture of the gingival tissue. Collagen type I dominates the gingival tissue, while type II, III and IV are present to a lesser extent. Changes in distribution and density occur in the inflamed gingiva. The aim of the study was to examine the organization and density of the collagen in healthy and inflamed gingiva. The material for the study consisted of the gingival biopsies performed in 96 patients aged from 13 to 70 years. The gingival specimens were classified into 4 groups: healthy gingiva, gingivitis, moderate periodontal disease and severe periodontal disease. The samples of the gingival tissues were stained by the method of Van Gieson’s Stain, while the VD of the collagen was measured bz the use of multipurpose testing system M42. In healthy gingival collagen are thick and receptive to color. In gingivitis collagen is mostly preserved structure, but reduced volume; in the periodontitis collagen bundles are reduced, short, thin, disorganized, often fragmented and less susceptibility to color. In healthy gingiva collagen fibers occupy 58.6 ± 5.1% of the volume of lamina propria; in gingivitis significantly lower (44.2 ± 6.2%); in moderate periodontitis 32.7 ± 8.5% and in the progressed periodontitis only 28.7 ± 9.7%. Based on our results, we concluded that in periodontal disease occurs collagenolysis. Quantitative evaluation of gingival collagen volume density may reflect the clinical severity of periodontal disease.

Patient fear from dental intervention is the most common cause of permanent disposal of the visits to the dentist by the patient , and there arise some magic circle in which symptoms of disease becomes more intensive , which proportionally increase the already present fear and further delay the visits to the dentist . The ultimate outcome is compromised oral health with early loss of teeth and chewing function , speech , etc. The aim of work is to determine the frequency of fear from dental intervention , occurrence of pain during certain phases of tooth extraction , its intensity , and justified fear of the patient from the most common oral surgery . The study includes 96 patients , aged 16-45 years , of whom 55 were male and 41 were female . For the assessment of fear of dental intervention was used Korah modified anxiety scale consisted of four questions ,in which every question has an answer and they are scored on a five point Likert scale . To determine the prevalence of pain in various stages of extraction there was used interview about the pain made up of three questions , and the sample consisted of patients divided by Kore scale into high and very high anxiety person. People who have positively responded to the questionnaire, the pain was further determined with visual analogue scale. For statistical analysis we used hi square test at a significance of level p<0,05. Modified Kore scale in a group of very highly anxious individuals were classified as 8 (7.68%), highly anxious individuals 15 (14.4%), moderately anxious individuals 31 (29.76%)and in the group of people without anxiety 42 patients (40, 32%).From a total of 23 patients identified as high and very high anxiety , only three (14%) felt the pain during the observation and characterized as a mild by using visual analogue scale as mild. By using Hi-square test (p<0,05) there were significant differences in responses( x²=12,6>5,92) . Five patients (22,74%) felt the pain during anesthesia where was found statistically significant differences in responses (X ²=7.34> 5.91) . Two patients (8.7%) registered the pain during tooth extraction and all the pain was characterized as mild to moderate. There was no statistically significant difference using the Hi square in the responses (x²=15,69>5,91 za p<0,05). The frequency of dental anxiety in our sample was very high in comparison with similar studies in the west of Europe, and the possible cause among other things, can be considered as a lower level of education of the population on which we must work. The emergence of real pain in high and very high anxiety patients during tooth extraction is very small, which indicate the unjustified fear of this type of intervention .

Leukoaraiosis is a change in brain white matter with characteristic manifestation in MR and CT head scans. Common leukoaraiosis risk factors include aging and arterial hypertension. A quarter of symptomatic ischemic infarcts belongs to small blood vessel disease group and could be presented as lacunar infarcts. These two crucial pathophysiological mechanisms are in the root of cognitive dysfunction related to small blood vessel disease. 60 lacunar infarct patients were examined and parameters for groups with and without leukoaraiosis were determined. It was found that leukoaraiosis incidence was highest in the group of women older than 70. Neurological assessment was scored on NIH-NINDS scale, functional status was scored with Barthelo index, and cognitive status was determined using Mini Mental State Examination (MMSE) and Alzheimer Disease Assessment Scale Late (ADAS-L). Correlation analysis of these parameters on significance level of *p<0.05, **p<0.01, suggests decrease in neurological status and cognitive performance.
