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.

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.

Prediktori pobolјšanja kvaliteta života nakon hirurške revskularizacije miokarda su još uvek nepotpuno poznati. Cilj rada je bio da ispita prediktore poboljšanja kvaliteta života šest meseci nakon hirurške revaskularizacije miokarda. Ispitivali smo 208 uzastopnih pacijenata koji su podvrgnuti hirurškoj revaskularizaciji miokarda. Za ispitivanje kvaliteta života korišćen je upitnik Nottingham Health Profile Questionnaire prvi deo. Upitnik se sastoji od 38 pitanja koji su podeljeni u 6 odeljaka: fizička pokretljivost, socijalna izolacija, emocionalne reakcije, energija, bol i san. Upitnik je podeljen svim pacijentima pre i šest meseci nakon operacije. Prosečna starost ispitivanih pacijenata je bila 58,8 ± 8,2 godine, 82% su bili muškarci. Poređenje pre i postoperativnih skorova je pokazalo da se poboljšanje nalazi kod 53,76% bolesnika, pogoršanje kod 12,46%, normalan KŽ pre i posle operacije kod 26,70%, dok je KŽ nakon operacije bez promene kod 7,08% bolesnika. Nezavisni prediktori poboljšanja kod pacijenata nakon operacije su bili: odsustvo prethodnog infarkta miokarda u odeljku fizička pokretljivost (p=0,03; OR=0,59; CI 0,40-0,92), viša CCS klasa angine u odeljcima fizička pokretljivost (p=0,006; OR=2,34; CI 1,46-3,32), energija (p=0,02; OR=1,70; CI 1,29-2,64) i bol (p<0,001; OR=4,64; CI 2,27-7,31), muški pol u odeljku bol (p=0,03; OR=0,45; CI 0,26-0,62) i mlađe starosno doba u odeljku bol (p=0,01; OR=0,69; CI 0,41-0,85). Prediktori poboljšanja kvaliteta života šest meseci nakon hirurške revaskularizacije miokarda su viša CCS klasa angine, odsustvo prethodnog infarkta miokarda, muški pol i mlađe starosno doba.

Suštinu biološkog lečenja caries profunda čini proces 'ozdravljenja' koji se zasniva na stimulaciji dentinogenetske funkcije pulpe, što omogućava stvaranje mineralizovanog tkiva. U eksperimentalnom istraživanju postavljen je cilj da se skening elektronskom mikroskopijom i polarizacionom mikroskopijom: Analiziraju promene na celularnim i ekstracelularnim komponentama zubne pulpe posle direktnog i indirektnog prekrivanja alkalnim cementom (Dycal), Utvrdi izgled dentinske površine posle direktnog i indirektnog prekrivanja pulpe i Formira predlog za kliničku primenu preparata Dycal ukoliko obezbeđuje dobru i efikasnu dentinogenezu. Ispitivanje je izvršeno na eksperimentalnim životinjama (domaća svinja). Za ovo istraživanje korišćen je alkalni cement Dycal. Na zubima eksperimentalne grupe uradjene su preparacije V klase sa vestibularne strane. Na jedanaest zuba je uradjeno indirektno, a na jedanaest zuba direktno prekrivanje pulpe. Nakon završene preparacije dentin je direktno prekriven alkalnim cementom Dycal. Preko Dycal-a je postavljena podloga cink fosfatnog cementa i materijal za definitivno zatvaranje kaviteta (amalgam). Na zubima gde je urađena perforacija komore pulpe Dycal je ubacivan direktno u komoru pulpe, a preko toga je postavljena podloga cink fosfatnog cementa i kavitet je definitivno zatvaran amalgamom. Adekvatno pripremljeni zubi i pulpa posmatrani su SEM i polarizacionim mikroskopom. Rezultati: Posmatranjem i analizom dobijenih rezultata, na polarizacionom i skening elektronskom mikroskopu u poređenju sa kontrolnom grupom, dobijeni su rezultati koji mogu imati značajnu kliničku implikaciju u biološkom lečenju pulpe. Dycal direktno apliciran u komoru pulpe: uočava se granica između novostvorenog reparativnog dentina u normalnu dentinsku strukturu, sreću se degradirane smežurane ćelije, zapažaju se jezgra kalcifikacije, mladi krvni sudovi i ćelije (fibrociti, histiociti i fibroblasti). Indirektno aplikovan Dycal: uočava se normalna dentinska struktura , jasno su vidljivi dentinski kanalići, a sreće se i atubulusna dentinska struktura, vidi se slika dentinske strukture koja prožima acelularno pulpno tkivo, hipercelularnost na granici stvaranja novog dentina i brojni krvni sudovi. Prisustvo amorfnog kalcifikata dentinske strukture govori o početnom stvaranju barijere od čvrstog tkiva što je cilj eksperimenta. Dobijeni rezultati eksperimentalnim istraživanjem sugerišu Dycal kao dobar materijal za direktno i indirektno prekrivanje pulpe.

Telemedicina je kao sistem pružanja zdravstvene zaštite, definisana od Svetske zdravstvene organizacije (SZO) kao praktična zdravstvena zaštita koja koristi interaktivnu zvučnu, vizuelnu komunikaciju i razmenu podataka.

Introduction: antibiotic prophylaxis in surgical patients is defined as the use of antibiotics to prevented infection of the operating field. Applies in cases where the infection is not clinically manifested. The aim of this paper is to demonstrate the importance of the prophylactic use of antibiotics in the prevention of postoperative infection for patient's inguinal hernia. Materials and methods: The making of the material used Surgical Clinic KBC Pristina in Gracanica, which is part of the "preventive use of antibiotics in surgical patients, through follow-up prospective study of 200 patients. The first group (study group-Group I) consisted of 100 patients with inguinal hernia, in which we apply the prophylactic use of antibiotics. Study group was divided into two subgroups: (Group IA), 50 patients with inguinal hernia in which the solution methods with installation of mesh. (Group IB), 50 patients with inguinal hernia where the tension applied in the treatment methods of treatment. In the second group of patients (control group-Group II) with the same number of patients in the postoperative tre- atment are therapeutic dose used antibiotics. Research results: In our study, the prophylactic purposes, we used compound II generation cephalosporine cefuroxime (Nilacef), which are given in intravenous bolus, the induction of anesthesia, in a dose of 1.5 grams. In 100 patients examined groups, we used prophylactic cefuroxime 100 ampoules (Nilacefa) of 1.5 grams, whi- le the treatment of 100 patients in the control group used for therapeutic purpose 894 ampoules of different antibiotics. Pos- toperative wound infection in patients with prophylactic application of antibiotics are not recorded, while we were in the gro- up where the applied dose of antibiotics therapeutics wound infection noted in two (2%) patients. The average number of days of treatment the study group, the postoperative period was 2.81 days, while patients with a therapeutic dose of antibiotics the average number of days was 5.28. Cost of treatment cefuroksim 50 patients, the prophylactic use amounted to 32,460RSD, while the cost of antibiotics applied in the postoperative treatment of the control group, in which we applied the therapeutic dose antibiotic treatment, was 253,961.52 RSD, which is 7.8 times more expensive. Conclusion: The prophylac- tic application of antibiotics reduced the non-critical use of antibiotics, the incidence of infection of the operating field, mor- bidity and mortality due to postoperative infection, the frequency of resistance to antibiotics, antibiotics to minimize the ef- fect of Bacterian normal flora of the patient, changes in the defense system of the patient, and thus the cost of hospital treat- ment of surgical patients.

There are different stick types and shapes, different root canal preparation techniques, as well as different materials for stick cementing and making annexes around posts. The use of fiber-reinforced resin posts to restore endodontically treated teeth has gained popularity due to its mechanical and esthetic characteristics as well as properties of modern adhesive systems. The aim of this article was to show a clinical technique to reconstruct endodontically treated teeth with great loss of tooth structure using direct fiber-reinforced post systems and direct composite restorations. After the preparation of the root canal and cementation of a FRR post, particular attention was paid to the incremental and curing techniques adopted to reconstruct coronal part of the tooth. It is possible to place of fiber-reinforced resin posts. 

Materials wich use like base,and those used for direct and indirect capping should be, except certain physicalchemical and biological performance have and antibacterial effect, to act after the application on residual microorganisms. The aim of this study is that in vitro display antimicrobial activity of some selected resources that are used to protect the dentin below the permanent restoration, and some of this as medication in treating deep surface carious lesions and to directly cover any caries, either artificially open pulp. Antimicrobial activity was tested against microorganisms. On agar plates into the grooves 4 mm in diameter was inserted freshly prepared paste or base. After inserting the material into the surface of bloî od agar, was performed by incubation under aerobic conditions for 24 h in a thermostat at 37 C. Negative effect on the microorganisms, tested materials, it was estimated by the size of growth inhibition zone.

Background: In hernia inguinal regions that are usually on the front wall of the belly may appear epigastric, umbilical and postoperative (incision-ventrale) hernia. Incision (postoperative-ventral) hernia is the kind of hernia that occurs in the area before surgical incision made through the entire thickness of the abdominal wall. Purpose: The aim of this paper is to indicate the frequency incision, epigastric and umbilical hernia, and the validity of some methods used in surgical treatment. Materials and methods: The making of the material used Surgical Clinic KBC Pristina in Gracanica. This prospective study we included 107 (3.43%) patients with hernia abdominal front wall, which were operated in the Surgical Clinic from 2003- 2009th year. Results and discussion: the anterior abdominal wall hernia, are recorded in 48 (44.86%) male patients and in 59 (55.14%) female patients. Age is of great influence on the frequency of anterior abdominal wall hernia, because we have the largest number of hernia 45 (43.14%) recorded in patients older than 61 years. Free hernia we found in 68 (63.55%) and hernia incarcerate of 39 (36.45%) patients. Incision (postoperative) we found a hernia in 44 (41.12%), umbilical in 36 (33.65%) and epigastric of 27 (25.23%) patients. Postoperative hernia is most often occurring after longitudinal laparotomia. We have them registered in 19 (43.18%) patients with infraumbilical, in 10 (22.72%) with supraumbilical, in five (11.36%) with subcostal, with four (9.09%) with transrectal, at two (4.55%) with pararectal laparotomia, in two (4,55%) patients after lumbotomia made with two (4,55%) after Phanensthil incision. The treatment of the anterior abdominal wall hernia in 72 (67.21%) patients, we used prolen net, while in 35 (32.79%) patients made plastic abdominal wall. Drainage was used in 62 (57.94%) operated patients. In 78 (72.90%) patients applied the prophylactic dose of antibiotics, while in 29 (27.10%) patients applied therapeutic dose. The length of treatment of patients who applied prophylactic dose of antibiotics was 2.48 days and length of treatment of patients with therapeutic dose applied was 4.82 days. Prospective studies of patients in the postoperative complications are recorded in four (3.74%) patients. We had wound infection in two (1.87%) and recidive hernia in two (1.87%) patients. Conclusion: This surgical method, when it comes to herniotomia, a direct comparison with the number of postoperative recurrence. Implantation of mesh has found its place and it is a revelation in the resolution of abdominal wall hernia.

Vital extirpation is microsurgical intervention.Wellknowing of internal morpfology of pulp cavity and with patience, carefull and precise work is possible to extirpate, dilatate and fil in both distal and mesial root of down molars,even if in mesial root exists two canal (buccal and lingual) what is the ruosh aften finding. Vital extirpation is very frequenthy used method in the treatment of multi-root teeth.It is more requested intervention tlak usnal once,but patients mane less visits at the dentist and the results one good enongh. So, one session method isacceptable as from medical point of view but endodontic too.
