Introduction: Soot usually occurs as a result of incomplete combustion of fuels containing carbon (fossil fuels - wood, coal). Air pollution is one of the most serious environmental threats to the urban population, which has harmful effects on human health, regardless of age. Objective to determine the extent to which the development of concentrations of soot in the air affects the air quality in the area tested. Methods: In the period from 2007. to 2011. the soot immission was followed at two sites: in Kosovska Mitrovica and Zvecan. The concentration of soot is determined by the reflectometric method. The statistical hypotheses were tested on statistical significance level of 0.05. Results: Overall, for both measuring points, there was a statistically significant change in value of the concentration of soot in the air (F = 6.779; p = 0.009). There was a significant increase in the concentration of soot in the air during the investigated years, with the highest values in 2010. and 2011. The average value of soot concentration for the period from 2007 to 2009 was 17.7 ± 21.3 mg / m while in the period from 2010. to 2011. it was 36.7 ± 45.2 µg/m , which represents a statistically significant difference (U = 910082.5; p<0.001). The amount of average concentrations of soot in the heating 3 3 season was 32.8 ± 44.2 µg/m while out of the heating season it was 16.8 ± 15.6 µg/m which is a statistically significant difference (U = 1030936; p <0.001). The distribution of average concentrations of soot in the air represented by month 3 showed the highest value in January at both measuring locations, in Kosovska Mitrovica 86.8 µg/m , and in Zvecan 34 3 µg/m . The total number of soot over the limit value in the period surveyed was in Kosovska Mitrovica 256 days, and in Zvecan 90 days.

Often the only available way of checking the adequacy of HD reaching dry weight after completion of dialysis treatment or monitoring arterial blood pressure. The goal of this paper is to show whether echocardiographic index measuring inspiratory collapse VCI can further assist in assessing the state of hydration of patients on HD. Method: In a study that we conducted on the UDK in Belgrade Centre for HD at 20 toro children on HD (before and after HD) and 20 healthy children, the control group. The M mode echocardiography we measured the diameter of the inferior vena cava (VCI) and calculated the index VCI inspiratory collapse. Also, accompanied by the correlation of these parameters with the dimensions of the left atrium, left ventricular in diastolic and body weight. Results: Children were before HD was significantly higher static diameter VCI and LA diameter compared to the control group (p <0.05). Index is collapsed before the HD was be substantially lower than in the control group (p <0.05). After HD LA diameter was still significantly higher than in the control group (p <0.05). while the other parameters were not statistically be substantially different. Index collapsing VCI differed significantly before and after HD (p <0.05), examining the correlation between VCI and diameter dimensions of the left ventricle during diastole (LVD) found a statistically significant positive correlation between these two parameters in all three groups of measurements (p <0.01). A statistically significant positive linear correlation was found between the VCI diameter and diameter of the left atrium (LA) in all three of measurements (p <0.01). A statistically significant positive linear correlation was found between the diameter of VCI and body weight in children after HD and control groups (p <0.01). CONCLUSION: Index collapsing and VCI in combination with other parameters can further improve the monitoring of the state of hydration and improve the quality of life of patients on hemodialysis.

Parodontopathy is a complex disease of periodontal tissues. The patological changes that occure here are destructive and lead to gradual or progressive periodontium disease and its anatomical and functional desintegration. The aim of the research was to use the PCR method (Polimerase Chain Reaction) to identify the presence and spreading of the oral pathogen Actinobacillus actinomycetemcomitans in subgingival plaque in patients suffering from the agressive parodontopathy and then compare it to qualitative-quantitaive structure of dental plaque in patients suffering from chronic parodontopathy. The study included 70 patients, average age of 45. The identification of microorganisms in subgingival plaque was determined by PCR method. In order to comfirm the diagnosis and determine the extent of destruction of periodontal tissue the standar epidemiological criteria were used: plaque index (Silness-Lӧe), gingival index (Lӧe-Silness), SBI index (Mühleman-Son) and DPP. Extremely high statictical significance of presence of A. actinomycetemcomitans was obtained in patients with agressive parodontopathy. The presence of A. actinomycetemcomitans and P. gingivalis showed the difference in distribution in patients with chronic as well as in patients with agressive pardontopathy. In our sample A.a was detected in a high percentage of younger patients with the diagnosis of agressive parodontopathy. Higher rate of A. actinomycetemcomitans in subgingival plaque has a direct impact on the course of parodontopathy. Its detection may be a useful marker for identifying the icreased risk for developing agressive parodontopathy in patients of younger population.

Introduction: Vitamin D Deficiency (VDD) is defined as the level of 25(OH)D in the serum < 30 ng/ml. According to the contemporary research, even the slight vitamin D deficiency can adversely affect our body in many ways. Numerous studies indicate that vitamin D deficiency is very common in children. The study aimed to research the frequency of vitamin D deficiency in infants and toddlers, the connection between VDD and iron deficiency anemia (IDA), as well as the correlation between 25-hydroxycholecalciferol (25(OH)D) and haemoglobin (Hb) in the examinees. Method: The study includes 150 children, 73 (49%) newborns and 77 (51%) infants. Vitamin D status was determined through the amount of 25(OH)D in blood, using the electrochemiluminescence. Results: Vitamin D Deficiency was found in 58% of infants and toddlers (severe vitamin D deficiency was found in 16% of examinees, vitamin D deficiency was found in 23% of examinees, while vitamin D insufficiency was found in 19% of examinees). Vitamin D deficiency (VDD) and anaemia were found in 80% of examined infants and toddlers. VDD was found in 49% of newborns that were not anaemic. We have observed the substantial difference between the examinees suffering from both anaemia and VDD and the examinees suffering from VDD only. Conclusion: The highest level on anaemia was found in the children with severe vitamin D deficiency, while in the examined infants and toddlers, there was a connection between the level of 25(OH)D and Hb in the serum.

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.

Fear of falling (FOF) is a significant health problem that can be present in the elderly, both in those that had experienced falling and in those that hadn`t. The aim of the study was to establish correlation of FOF with the following characteristics of the participants: sex, age, education, marital status and the number of falls in the previous year. Performed from October to December 2014, the research included 100 participants from general population older than 65 and covered by health visiting service of Dom Zdravlja Nis. The questionnaire for assessment of FOF - Falls Efficacy Scale (FES) and the epidemiological questionnaire were used in all participants. We established that there is statistically significant difference of FES values (hi-kvadrat=7.668, p<0.05) between different age groups. It was found that median value of FES questionnaire is statistically significantly higher in participants living as singles in relation to those living in a community (U=828.0, p<0.05). There is satistically significant medium correlation between FES values and the number of falls in the previous year (r=0.661, p<0.01). This research established that FOF is associated with age and the number of falls in the previous year, that implies the need for prevention of FOF, especially in elder people and in people that experienced one or more falls. Implementation of prevention is also important in people living alone because FOF is excessive in their case.

Karcinom grlića materice je ozbiljan javno zdravstveni problem kako u svetu tako i kod nas. Kontrola karcinoma grlića materice pored prevencije podrazumeva ranu dijagnostiku i lečenje, ali i preciznu registraciju i praćenje obolelih žena. Da bi bila obezbeđena dobra kontrola bolesti, svi ovi delovi sistema moraju funkcionisati paralelno. Cilj rada je sagledavanje osnovnih deskriptivno-epidemioloških karakteristika obolelih i umrlih žena od raka grlića materice u svetu, Evropi i Srbiji. Poseban osvrt i detaljan epidemiološki prikaz usmeren je na područje centralne Srbije za period od 1999. do 2011. godine. U radu je primenjen deskriptivno-epidemiološki metod. Kao izvor podataka korišćeni su podaci Globocan-a (softver za procenu opterećenja bolesti populacije, pokrenut od strane WHO), kao i podaci Registra za rak centralne Srbije za analizirani period. U svetu, broj novoobolelih slučajeva za 2012. g. je 527624 (standardizovana stopa incidencije je 14,0 na 100000 žena). U pogledu mortaliteta, za dotičnu godinu broj umrlih žena je 265653 (standardizovana stopa mortaliteta je 6,8 na 100000 žena). Od karcinoma grlića materice na svaka 2 minuta u svetu umre jedna žena (720 dnevno). U Evropi, ukupan broj novoobolelih žena za 2012. g. je 58348 (11,44 na 100000 žena). Ukupan broj umrlih žena je 24378 (3,75 na 100000 žena). U Srbiji, ukupan broj novoobolelih žena za 2012. g. je 1501 (23,8 na 100000 žena). Ukupan broj umrlih žena je 609 (7,7 na 100000 žena). Pozicija Srbije u Svetu u pogledu obolevanja je 62 (od 182. zemlje), dok je 84. u pogledu mortaliteta, što nas svrstava u gornju polovinu liste svih zemalja u svetu. Prema podacima Registara za rak za centralnu Srbiju, prosečna standardizovana stopa incidencije od 23,9/100000 žena i mortaliteta od 7,2/100000 za period 1999-2011. godine ukazuju na nepovoljnu epidemiološku situaciju ovog malignoma u centralnoj Srbiji. Mada se analizom pomenutog vremenskog intervala registruje blagi pad trenda obolevanja u centralnoj Srbiji (y=27,13-0,47x; p>0,05, otprilike jedan slučaj karcinoma grlića materice na 100000 žena manje za sledeće dve godine). Naprotiv, za isti analizirani period, beleži se porast umiranja (y=7,16+0,01x; p>0,05).
