The aim of the present study is to investigate the antioxidant properties of the lichen Cetraria aculeata. Antioxidant activity of the methanol and ethyl acetate extracts of lichen was tested by different methods including determination of total phenolics content, determination of total antioxidant capacity, DPPH free radical scavenging activity, inhibitory activity towards lipid peroxidation, ferrous ion chelating ability and hydroxyl radical scavenging activity. The extracts of the lichen C. aculeata showed significant antioxidant activity. The methanol extract showed higher values for total phenolics and total antioxidant capacity compared to the ethyl acetate extract, while the ethyl acetate extract demonstrated better results for DPPH radical scavenging, inhibitory activity towards lipid peroxidation, chelating ability and hydroxyl radical scavenging than the methanol extract. This is the first report of the antioxidant properties of Cetraria aculeata growing in Serbia. The results of antioxidant activity indicate the application of this lichen as source of natural antioxidants that could be used as a possible food supplement, in the pharmaceutical industry and in the treatment of various diseases.

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.

Tests have shown that adipose tissue is very important in the production of chemical substances that have a major impact on atherosclerosis. The basic fat cells adiposity is very active in bio secretion hormones and other substances. Adiposities secrete chemical substances such as leptin, resistin, adiponectin, and others who participate in metabolic processes. One of the most important adipocytokine affecting the formation and the regression of atheromas plaque in the coronary blood vessels are adiponectin and resistin. So our aim was to determine the value of the concentration of adiponectin and resistin on patient with myocardial heart attack and determine their correlation with the control group of healthy subjects. In this study were included 68 subjects, 40 with myocardial heart attacks and 28 control groups of normal healthy. In the group with myocardial 78.6% of respondents were male and 21.4% female. Tests have shown that the concentration of adiponectin in the group with myocardial heart attack was significantly lower than the control group (4.94 to 6.74, p=0.043, 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) (Student's t-test, p = 0.581, p> 0.05). All this indicates that in patients with myocardial heart attack there is a decline in the concentration of adiponectin, which has cardio protective effect. The increase in resistin in myocardial heart attack in directly related to the appearance of athermanous plaques in the coronary blood vessels and has a bad prognostic significance.

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.

Meniscus injuries occupy an important place among damages to the knee joint and are crucially important for athlets. Arthroscopy is a method of choice in both diagnostic as well as therapeutic treatment. After the intervention, it is necessary to start physical tretmeant as soon as possible. The study presents the treatment of 14 year old female patient, who started physical therapy five days after the removal of part of the lateral meniscus. Procedures involved electrical and kinesy therapy. Within the kinesy treatment static contractions were included, lymphatic drainage, and also passive exercises in order to increase range of motion. In the end, exercises against resistance were conducted to strengthen the musculature. After one month of therapy the treatment was completed, and patient was advised to continue strengthening the musculature at home. During the last examination the absence of swelling was noted, with painful sensitivity and limited motion in the knee. The MMT score for qvadriceps femoris was 4. The patient was advised to start with the lighter recreative activities. Arthroscopic meniscotomy is relatively rare intervention with adolescents, which was the motive for displaying this case. Applying early rehabilitation is fully exploited regenerative potential of this age and the optimal time for patients to return completely to usual activities.

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).

Introduction: The study of importance of left ventricular contractile reserve presence and changes plasma brain natriuretic peptide levels (BNP) during exercise in patinets with idiopathic dilated cardiomyopathy is very popular today, but these two parametres have rarely been interconnected. The study of response BNP during echocardiography stress tests in patients with idiopathic dilated cardiomyopathy with or without preserved left ventricular contractile reserve. We studied 55 consecutive patients with idiopathic dilated cardiomyopathy (mean age 54.98 ± 9.84, 49 (89.1%) male) treated in the outpatient clinic for heart failure at the Institute of Cardiovascular Diseases "Dedinje". All the patients underwent the echocardiography stress test. Contractile reserve was assessed by measuring of the changes of the left ventricle ejection fraction basally and in the first minute after the strongest stress. Level of BPN was measured at rest, in the first minute and after 20 minutes of maximal exercise stress. Following the kinetics of BNP level during stress testing, we find that in patients with preserved left ventricular contractile reserve BNP level is rising at maximum load achieved (Mediana (IQR) - 59 (22-113) vs. 91 (37-135) vs. 78 (30-159) ng/L, p<0.001), whereas in patients without preserved left ventricular contractile reserve BNP level does not change significantly (Mediana (IQR) – 89 (50-322) vs. 119.5 (61.3-321.8) vs. 136 (72- 281), p=0.102). The increase in BNP in the peak load compared to its value at rest was positively correlated with preserved contractile reserve (r=0.38, p=0.009), better WMSI at rest (r=-0.28, p=0.04), greater difference in the double product (r=0.40, p=0.002), as well as the work accomplished on the test (r = 0.47, p <0.001), and longer duration of the test (r = 0.43, p = 0.001). The increase in BNP during physical exercise in patients with idiopathic dilated cardiomyopathy suggests a preserved contractile reserve of the left ventricle.

Savremeni akcenti u tretmanu varikocele. Postići “minimalnu invazivnost” tretmana, odrediti broj trudnoća nakon operacije i ustanoviti vremenski period od operatvnog zahvata do začeća kod partnerki. Selektovana grupa muškaraca pomoću uroloških kriterijuma za infertilni par, tretiranih subingvinalnom ligaturom spermatične venepampiniformnog pleksusa. Tretirali smo 26 subfertilnih muškaraca kombinacijom subingvinalne ligature spermatične vene ili pampiniformnog pleksusa i medikalmentozne terapije.U desetogodišnjem periodu, registrovali smo 16 trudnoća (61,5%) partnerki naših pacijenata. Smatramo da je subingvinalna ligatura spermatične vene minimalno invazivan i isplativ početni tretman “infertilnih parova”.

Quality of life (QoL) is used in the natural and social sciences as a relatively new category which deserves more attention in research. Quality of life related to health is a term commonly used when QoL on health. An increasing number of research studies that are based on an examination of the QoL. This paper analyzes the concept of the QoL, the possibilities of measuring the QoL, a special emphasis is placed on measuring QoL in dermatovenereology. Given that the skin disease are of particular significance for the patient, the said indices are dermatologically quality of life, especially the quality of life of patients dermatological (DLQI).

Maligni tumori pljuvačnih žlezda su retka oboljenja i u najvećem broju se javljaju u velikim pljuvačnim žlezdama. Cilj istraživanja bio je da se analizira trend incidencije malignih tumora velikih pljuvačnih žlezda kod stanovništva grada Beograda. Podaci su dobijeni iz Registra za maligne tumore centralne Srbije. Analizirani su svi slučajevi malignih tumora velikih pljuvačnih žlezda registrovani u Beogradu od 01. januara 1999. godine do 31. decembra 2010. godine. Trend kretanja i godišnji procenat promene incidencije izračunat je regresionom analizom uz pomoć tačaka spajanja (engl. joinpoint regression analysis). U ispitivanom periodu Registru je prijavljeno je 283 pacijenta (168 muškaraca i 115 žena) sa malignim tumorima velikih pljuvačnih žlezda. Standardizovana stopa incidencije svih tumora u ispitivanom periodu, za oba pola, bila je 0,87/100,000 stanovnika, odnosno 1,13 za muškarace i 0,67 za žene. Standardizovana stopa incidence se uvećavala sa godišnjim procentom promene od 6,4% kod oba pola (p<0,001). Rezultati su pokazali konstantno povećanje trenda incidencije malignih tumora velikih pljuvačnih žlezda kod stanovništva grada Beogradu između 1999. i 2010. godine.
