One of the best-studied responses of cognitive evoked potentials is a so-called “P300”, the late positive wave complex that occurs about 300-500 ms after the stimulus. It is obtained when the subject’s attention is focused on a signal that is rare, especially if the signal has a motivational or emotional meaning. In the study of P300 potential, we followed the variations of potential amplitude and latency, so the objective was to examine whether there is a difference in Fz and Cz amplitudes of auditory induced cognitive evoked P300 potential depending on the performance of oddball tasks, both in male and female subjects. The study included 60 subjects (30 female respondents and 30 male respondents). P300 potential is induced by the auditory "oddball" paradigm with 80% of non-target and 20% of target stimuli that are presented to the patient through headphones. The target tones are high tones of 2000 Hz. The standard, 1000 Hz tones the respondent should ignore but when he hears the target tones the respondent should press the button on the special handle. The value of Fz and Cz amplitudes both in male and female subjects obtained in the classical "oddball" paradigm when the subject reacted to the signal by pressing the key with the dominant (right) arm were statistically significantly lower (p>0,05) than the values of Fz and Cz amplitudes obtained when the key was pressed by the non-dominant hand. Based on this experiment it can be concluded that both in male and female subjects the performance of oddball tasks does not affect the amplitude of P300 cognitive evoked potentials.

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.

Najčešći maligni tumori kože epidermoidnog porekla su bazocelularni (BCK) i skvamocelularni (SCK) karcinom. U 90 % slučajeva nastaju na fotoeksponiranim delovima tela i direktno su povezani sa oštećenjima kože nastalim dugotrajnim izlaganjem UV zracima, obično kod osoba starijeg životnog doba i svetle puti. Od njihovih posledica godišnje u svetu umre 65000 ljudi. Najvažnija karika u sprečavanju nastanka ovih tumora jeste prevencija, dok njihovo rano prepoznavanje omogućava adekvatniji hirurški tretman sa poštedom okolnog tkiva. Osnovni cilj ovog rada je ispitivanje histopatoloških i kliničko-morfoloških karakteristika BCK i SCK kože glave. Analizom je obuhvaćeno 439 karcinoma (297 (67,7%) BCK, 126 (28,7 %) SCK i 16 (3,6%) BCK+SCK), među kojima je preko 60% dijagnostikovano kod muškaraca, najčešće u sedmoj i osmoj deceniji života, sa najvećom učestalošću BCK na nosu, odnosno na koži gornje polovine kože lica i SCK na usnama, odnosno na koži donje polovine kože lica. Svi karcinomi kože glave bili su češći na desnoj strani. Klinički i morfološki, najveći broj BCK manifestovao se ulceroznim oblikom prosečne veličine 1,2cm i mešanim histološkim tipom, a SCK vegetantnim oblikom prosečne veličine 1,55cm i histološki gradusom I. Najveći broj BCK i SCK bio je odstranjen u celini, za razliku od kombinacije ova dva tumora u kojima je u većini slučajeva bila neophodna i naknadna hirurška intervencija.

During the armed conflict in Kosovo and Metohija, and after it, were killed more than 5 000 people, and according to the International Red Cross Committee in March 2001, 3,338 people were still missing. Until the conclusion of this study, the number of missing persons in Kosovo and Metohia for which the trail is about 1700. This list includes people from all ethnic communities. The primary objective of the forensic investigation is to determine the identity of the missing persons and after that their remains returne to the families, in accordance with Geneva protocols. Experts post-mortem examination after the exhumation determine the cause and manner of death, which indicates a violation of human rights and war crimes.Conclusion. We are facing with reasonable fear that with the passage of time, less interest will be devoted to this issue and the activities on finding and identifying missing persons will completely stop.

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).

The mos Tooth whitening is a procedure that removes stains and various discolorations of tooth surface. Discoloration of teeth may be endogenous and exogenous nature. The aim of this study was to investigate the impact of bleaching combined with daily use of drinks that cause tooth discoloration. Evaluated the changes in surface structure of enamel, and changes in hardness after bleaching. Were 20 extracted teeth. The teeth are marked with longitudinal lines halves (medial vestibular and distal surfaces). Tretitana mesial half of the 16% carbamide peroxide, a distal was left as control. NDT device HL400DL, duroskopskom method of enamel hardness was measured before treatment, after treatment and after remineralization. Olympus inverted microscope GX41 enamel structures were observed in the treated and control half of the tooth. After bleaching there is a difference compared to the untreated surface, that surface is bleached a few shades lighter, but after the use of coffee and soft drinks teeth back to the original dark color. Enamel microhardness after the treatment is somewhat small but not significant. With a magnification of 2000x and see the structural changes in enamel. Tooth whitening, but that the remineralization and the abstinence from prebojenih beverages and tobacco.

Preterm premature rupture of membranes (PPROM) is in obstetrics with incidence of 0,4% of , with risk for chorioamnionitis 35%, risk for premature deli very 19%, and sepsis risk of 1%. Primary risk for fetus is pulmonal hypoplasia due to oligohydramnios in 29%, RDS in 66 % of such pregnancies, sepsis in 19%, and contrac ture of extremities in 3%. Fetal death is more than 30% of cases. Patient came to regular pregnancy check up in 22th week of gestation. US exami nation revealed decreased fluid volume AFI 50, with regular morphology and fetal dynamic. She was admitted to hospital. She was given cortico-steroids and antibiotics. In further course of pregnancy amniocentesis was performed in 32th week of preg nancy to rule out the infection and to check pulmonal maturity. In absence of infection and lung maturity pregnancy was continued until 36th week of gestation when Cesarean Section was. Baby went well and is now healthy child in the age of three. Some studies suggested that delivery can be significantly prolonged. In our case we menaged to gain 14 weeks,from 22th to 36th gestational week. Firstly gynaecologyst nightmare to ask the woman is she accept therapy. The aim is to deliver a healthy child without neurological and other consequen ces and mother with preserved reproductive function. Controversy still exists when is the appropriate time to finish pregnancy with prolonged PPROM.

Transposition veins, in some cases when there is no adequate superficial veins, preferred is model of the vascular access. This approach may be acceptable version vascular access where is not possible to create other shapes. But basilic vein transposition is time consuming and technically challenging procedure with significant perioperative morbidity. Complication rate for basilic vein transposition remains high at 47-71%. We report a patient who underwent transposition basilic vein, and its anastomosis with radial artery, in which developed the digital hypoperfusion ischemic syndrome.

Postoje brojni faktori koji mogu da utiču na kraniofacijalnu morfologiju, prvenstveno genetski faktori i faktori spoljne sredine. Cilj ove studije je da se na onovu podataka dobijenih pregledom školske dece dobije približniji opis kraniofacijalne morfologije na ovoj teritoriji. Istraživanjem je bilo obuhvaćeno 330 dece starosti od 8 do 11 godina. Za ovu studiju koristili smo standardne antropometrijske metode za merenje širine i visine lica, širine i dužine lobanje i izračunavanje indeksa lobanje i lica. Dobijeni rezultati su statistički obrađeni a Z skorom izračunat indeks kraniofacijalne varijabilnosti (CVI). On na numerički način opisuje varijabilnost kraniofacijalne morfologije i postojanje slučajeva izvan opsega ovog indeksa. Prema prosečnim vrednostima indeksa lica dečaci i devojčice u gotovo svim ispitivanim godištima pripadaju kategoriji mezoprozopa (47.4%). Analize indeksa lobanje kod dečaka i devojčica govori da su najcesce zastupljeni brahiokefali (52.2%), zatim mezokefali (43.5%) i dolihokefali (4.3%).
