Introduction. The protective ileostomy is a procedure that is now increasingly used after the creation of low colorectal anastomosis, and after resection of rectal cancer. The protective ileostomy is a procedure that, to a lesser extent, affects the prevention of anastomotic colorectal dehiscence, but it has a much greater signifi cance in reducing the severity of complications occurring after colorectal anastomosis dehiscence. However, the creation itself, as well as the closure of loop ileostomy are accompanied with certain complications. Aim of the study. The aim of this study was to determine the frequency and severity of complications of ileostomy and justifi cation for its creation, within the test sample of 42 patients. Patients and Methods. The study was designed as a retrospective-prospective study. 42 patients. with created protective ileostomy that occurred after low colorectal anastomosis, were included in the study. The average age was 64.38 years with a standard deviation of 9.63 years. The youngest patient was 36 years old and the oldest patient was 77 years old. The representation of patients by gender was 29 (69%) male patients and 13 (31%) female patients. During the study, functions and complications associated with the created loop ileostomy, as well as the need for surgical treatment and the period until the sinking of ileostomy were monitored in patients. Results. Out of the total number of observed patient complications of ileostomy occurred in 8 of them (19%), and in 34 (81%) patients there were no complications. Out of the total number of complications, only in cases of 2 (4.8%) patients , there was the need for surgical treatment. In 1(2.4%) patient, ileostomy remained permanently. Conclusion. This study showed that the loop ileostomy after the creation of low colorectal anastomosis is accompanied with fewer complications. The resulting complications are successfully disposed by conservative treatment, and only rarely require surgical re-intervention.

Background: The current standard treatment of chronic hepatitis C in Bosnia and Herzegovina consists of pegylated interferon alpha in combination with ribavirin. Interferon therapy has many psychiatric side effects, with depressive symptomatology being most prominent. The aim of the study was to establish the frequency and severity of depression in patients with chronic hepatitis C during two months of the aforementioned therapy. Subjects and Methods: The overall sample consisted of 46 subjects, divided into three subgroups, aged 18 to 65. The study population consisted of subjects treated for chronic hepatitis C (n = 15), subjects infected but not treated for chronic hepatitis C (n = 15), and healthy controls (n = 16). The assessment and level of depression were based on the Structural clinical interview (SCID), Montgomery-Asberg Depression Rating Scale and Zung Self-Rating Depression Scale. The assessments were conducted before interferon therapy (on the day 0), after 4 and 8 weeks of therapy. Results: Regarding its frequency, MADRS scoring showed that the number of depressed subjects receiving therapy increased after 8 weeks (46.7%). There was statistical significance between the subgroups after 4 and 8 weeks. Likewise, the ZUNG scale showed that the number of depressed subjects receiving therapy increased after 8 weeks (73.3%). There was statistical significance between the subgroups on the day 0, after 4 and 8 weeks. Conclusions: Depression was significantly more frequent in chronic hepatitis C subjects treated with interferon alpha in combination with ribavirin than in subjects in the group without therapy. Mild depression was most prevalent.

This paper presents a framework for determining the price of power and energy at each node in distribution network as well as the price of energy losses in their elements. The proposed framework is based on the concept of the radial structure network and gives one approach to solving the pricing problem that is based on purchase price of power and energy at the network supply point. In this way it is possible to determine the economic value of energy losses whether in the network as a whole or in particular voltage levels. The model has been successfully tested and results from test studies are reported.

Background: The risk of wound infection after elective inguinal hernia repair depends on several factors. One of the most important factors is the preoperative skin preparation. The use of antisepsis is performed to reduce the risk of surgical site infections (SSIs) and to remove causing organisms. This work compares two different agent forms for preoperative skin preparation to prevent SSIs. Objectives: The objective of the study is comparing the effects of two different agents used for preoperative skin preparation and prevention of SSIs. Material and methods: 100 adult patients were divided and randomized into two groups, each containing 50 patients. Both groups included patients that are scheduled for elective Lichtenstein inguinal hernia repair. The first group includes patients whose skin preparations were done with povidone iodine (PI) only. The second group included patients that are treated with two antiseptics; Alkosol (96% ethanol, isopropanol-30g and ortophenilphenol-0.1g) and povidone iodide. Alkosol is applied before the induction of anesthesia. The povidone iodide is applied after Alkosol has evaporated. The presence of bacterial growth in the wound was determined 24 and 48 hours after operation. Swabs were used to take samples, which were then cultivated to check for bacterial growth. The presence of infection was also determined by the following criteria: pain or tenderness, induration, erythema, local warmth of the wound etc. Results: The surgeon or clinician declared that after 24 hours the wound was infected in 20 patients in the control group and in 22 patients after 48 hours. In the Alkosol (96% ethanol, isopropanol-30g and ortophenilphenol-0.1g) and povidone iodide group infection was declared in only 3 patients after 24 hours. Discussion: Compared to the use of providone only, the use of Alkosol (96% ethanol, isopropanol-30g and ortophenilphenol-0.1g) and povidone iodide has many advantages and was associated with lower rates of SSIs following clean surgery. A larger trial is warranted in order to add definitive and more conclusive data to the current evidence base.

<p style="text-align: justify;">In this paper, the possibility of proportioning self-compacting concrete with high volume calcareous fly ash (W) for precast elements has been investigated. So far, numerous mix design methods for self-compacting concrete have been developed, so as the most appropriate method in this investigation, the UCL method was chosen. In the first phase, the preliminary tests were conducted on the mortar mixtures using mini slump cone and mini V-funnel, and thereafter the optimal mixture composition was defined. In the second phase, self-compacting concrete mixture was prepared and tested. In the end, based<br />on the defined recipe, the precast elements were made and their properties were tested. On the basis of the examinations, it was found that it is possible to obtain high quality self-compacting concrete by using the relatively simple procedure according to the UCL method.</p>
