Uvod. Infekcije urinarnog trakta (IUT) su poslije respiratornih, najcesce infekcije u djecjem uzrastu.Cilj rada je bio utvrditi ucestalost urinarnih infekcija, njihove etioloske i klinicke osobitosti kod djece u prvoj godini života, koja su hospitalizovana na Klinici za djecje bolesti tokom jednogodisnjeg perioda. Metode. Istraživanje je provedeno u periodu od 01.01.2010. do 31.12.2010. god. na Klinici za djecje bolesti Banja Luka. Analizirano je ukupno 126 pacijenata uzrasta 0–12 mjeseci kod kojih je verifikovana IUT. Svi pacijenti su podijeljeni u 4 starosne grupe (I: 0-28 dana života; II: 29 dana-3 mjeseca; III: 4-8 mjeseci; IV: 9-12 mjeseci). Ispitanici su podvrgnuti ispitivanjima koja su, zavisno od indikacija, obuhvatala laboratorijske i mikrobioloske testove, ultrazvuk abdomena i mikcionu cistouretrografiju. Rezultati. Djeca hospitalizovana zbog IUT u prvoj godini života ucestvuju u strukturi ukupnog hospitalnog morbiditeta sa 3,18%. Infekcije se cesce javljaju kod djecaka, sto je posebno izraženo u novorođenackom periodu, (79% djecaka prema 21% djevojcica). Infekciju po tipu akutnog pijelonefritisa imalo je 110 (87,3%) djece. Kod 50% dojencadi IUT se ispoljila u prva 3 mjeseca života, zatim od 4–8 mjeseca. Najcesci izolovan uropatogen je Escherichia coli (52,38%), oblik terapije parenteralni (96,03%), a ukupno trajanje terapije 8–10 dana. Na ultrazvucnom pregledu abdomena znake prosirenog pijelokanalnog sistema imalo je 31,75% djece. Od ucinjene 43 mikcione cistouretrografije vezikoureteralni refluks je nađen u 23,2% djece. Zakljucak. IUT su se najcesce javljale u prva 3 mjeseca života, po tipu akutnog pijelonefritisa sa nespecificnom simptomatologijom, cesce kod djecaka. Najcesci uropatogen je bila Escherichia coli, a nacin lijecenja parenteralni. Vezikoureteralni refluks je nađen kod 23,2% djece kod koje je ucinjena mikciona cistouretrografija.

We investigate global dynamics of the following systems of difference equations: {xn+1=b1xn2A1+yn2,yn+1=a2+c2yn2xn2,n=0,1,2,…, where the parameters b1, a2, A1, c2 are positive numbers and the initial condition y0 is an arbitrary nonnegative number and x0 is a positive number. We show that this system has rich dynamics which depends on the part of a parametric space. We find precisely the basins of attraction of all attractors including the points at ∞.

Introduction: Angiomyofibroblastoma is a tumor which is consists of two components: blood vessels and stromal cells, with always prominent vascular component. Angiomyofibroblastoma is benign tumor, but in literature is reported a case of recurrence and one case with sarcomatous transformation, which shoved that these tumors may rarely be associated with malignant component. Case report: A 78-year-old multiparous housewife was hospitalized at University Clinical Center because of painless, asymptomatic tumor of vaginal portion (posterior side). Tumor size was 7 millimeters in diameter. Internal genital organs did not present abnormalities. The patient underwent operative removal of the tumor and went to home at some day. At the histological examination the tumor presented as a angiomyofibroblastoma cervices uteri.

Objective: In our study we wanted to showed the safety, feasibility, efficacy and way how to solve the problems of endovascular repair for aortic dissection with insufficient proximal Landing Zone. Methods: The clinical data of all the patients with insufficient proximal Landing Zone (PLZ) for endovascular repair for aortic aneurism and dissection Stanford type B for the period from October 2013 to June 2014 was prospectively reviewed. According to the classification proposed by Mitchell et al, aortic Zone 0 was involved in 3 cases, Zone 1 in 1 case, Zone 2 in 9 cases and Zone 3 in 6 cases (19 patients in total). A hybrid surgical procedure of supraortic debranching and revascularization, with direct anastomosed truncus brachiocephalicus and left common carotid artery, were performed to obtain an adequate aortic PLZ. Revascularization of the left subclavian artery was carried out on the patient with dissection Stanford type B and short PLZ 2. Results: There was no significant difference of risk factors between Zone 0, Zone 1, and Zone 2 (Table 1.), but the length of the PLZ significantly differed between groups (p<0.01) and there is no significant difference in technical and clinical success rate among the groups. Conclusion: The procedure of extending insufficient PLZ for endovascular repair for aortic arch pathology is feasible and relatively safe. The TEVAR applicability in such aortic disorders could be extended.
