INTRODUCTION Appendicitis is one of the most common diseases that require urgent surgical intervention. Due to its position, the inflamed appendix can cause many complications in abdominal cavity. Most of these complications are based on the anatomical position of the appendix. According to world literature over 65% of the anatomical positions of appendix is retrocaecal position, followed paracaecal and then the other positions of the appendix in different percentages. GOAL The main goal of this research is to shown that anatomical retrocaecal position of the appendix can lead to prolonged hospitalization and more often occurrence of appendicitis complications. MATERIAL AND METHODS The research is based on patients who had appendectomy during 2009 at the Cantonal Hospital Zenica and General Hospital Tesanj. The study included approximately 400 respondents and the method of research was of retrospective, descriptive and analytical type. RESULTS AND DISCUSSION According to the results of this research we can conclude that in our country is not devoted enough attention to the anatomic position of the appendix and that we are not using enough diagnostic methods such as ultrasound and CT in determining the anatomic position to help determine the course of the disease. CONCLUSIONS Retrocaecal appendix position according to the obtained data from this study did not cause many complications in classical appendectomy but this can be attributed to insufficient observation of the anatomical position of the appendix.
UNLABELLED Anatomical variations of veins often play a crucial role in formation of thrombotic changes in superficial and deep veins of lower extremities. THE AIM of this study was to determine the frequency of the dominant type of the lower extremity superficial veins, and to determine the eventual influence of such variations to the formation of superficial and deep vein thrombosis (DVT). MATERIAL AND METHODS The sample used in this study consisted of 180 patients subjected to ascedent contrast phlebography of lower extremities. The total sample was divided into following groups: patients with and without variations of the lower extremity superficial veins. RESULTS AND DISCUSSION Dominant type of the superficial veins (without variation) consisted of 97 patients (53.89%), while the rest of 83 patients showed some kind of anatomical variation (46.11%). The most frequent variation was the duplicated form ofv. saphena magna in 53.85%, while this procentage in women was 57.89%. Most frequent variations of duplicated v. saphena magna were: simple duplicated form, closed loop form, branching form and combined form. Topographical variation of saphenopopliteal junction besides fossa poplitea in the group of men showed procentage of 53.85%, while in the group of women that value accounted 63.16%. CONCLUSION The percentage of varicose veins was more frequent in men and women without variations, but deep vein DVT showed higher frequency in patients with anatomical variations of superficial veins of lower extremities.
Introduction: Pulmonary thromboembolism (PTE) is the most serious manifestation of thromboembolic disease. Objective: To determine the most common risk and etiologic factors of pulmonary tromboembolism in patients treated in Intensive care unit of Clinic for Pulmonary Diseases and TB “Podhrastovi” in three-year- period from 2008. to 2010. Material and methods: We retrospectively analysed patients with PTE treated in Intensive care unit of Clinic for Pulmonary Diseases and TB “Podhrastovi” in three-year period from 2008. to 2010. PTE was diagnosed by high resolute computed tomography, in most of them ventilatory /perfusion scintigraphy (V/P SPECT) was made, with proper laboratory analyses (D-dimmer, platelets , fibrinogen, and if it was needed protein C, S and AT III factor were examined). In all of them echosonography of abdomen and pelvis was done, also the examination by angiologist, and in patients with indications echosonography of the heart and Color Doppler of leg veins was made. We analysed risk and etiologic factors for PTE in each patient. Results: In 222 treated patients with PTE risk factors were found in 124 or 55.86% patients, etiologic factors were found in 31 or 13.96%, and both risk and etiologic factors in one patient were found in 18 or 8.11% patients. Conclusion: PTE is very serious disease that very often has fatal prognosis, and can develop with previously entirely healthy people, and as soon as we become suspicious of its presence we have to made appropriate diagnostic procedures and include appropriate therapy. We can after look for risk and etiologic factors and try to influence them.
It is always a problem to choose one or more indicators or to construct a model that reflects the achieved operating result. Companies all over the world have developed numerous models assessing excellence from various aspects in order to estimate the achieved operating result or overall business excellence. Applying most of the models requires data and estimation that are not available to investors. BEX model is primarily designed to assess business excellence enterprises in the capital market in Croatia. It is also possible to apply this model to all the other similar markets. This paper will be focused more on the possibility of applying the mentioned model in the capital market of Bosnia and Herzegovina, that is, to the most successful companies listed on the Sarajevo Stock Exchange but being a part of SASX - 10 index, and those listed on the Banja Luka Stock Exchange entering BIRS index.
The technical analysis of a hybrid wind-photovoltaic energy system with hydrogen gas storage was studied. The market for the distributed power generation based on renewable energy is increasing, particularly for the standalone mini-grid applications. The main design components of PV/Wind hybrid system are the PV panels, the wind turbine and an alkaline electrolyzer with tank. The technical analysis is based on the transient system simulation program TRNSYS 16. The study is realized using the meteorological data for a Typical Metrological Year (TMY) for region of Novi Sad, Belgrade cities and Kopaonik national park in Serbia. The purpose of the study is to design a realistic energy system that maximizes the use of renewable energy and minimizes the use of fossil fuels. The reduction in the CO2 emissions is also analyzed in the paper.
The raw clay “Klokoti” from middle Bosnia was beneficiated by method of wet separation which results in removing fraction over 20 μm. The raw clay was characterized by chemical composition, grain size distribution and characteristic temperatures on heating microscope. The beneficiated clay was characterized by chemical composition and characteristic temperatures. The phase composition of raw and beneficiated clay was observed by RDA while the microstructure was monitored on scanning electron microscope (SEM). The sintering process was performed at 1100oC, 1250oC, 1320oC and 1400oC with two hours holding time at the highest temperature. The obtained results indicate a big content of coarse quartz in raw clay and gradually increase of crystalline mullite content with increasing temperature of sintering. Beneficiated clay at higher temperature of sintering produces larger glassy phase content, which is result of larger fluxing content in its composition. It is also observed that from beneficiated clay by sintering at 1250°C crystallize the most mullite along with minimum porosity and the lowest glassy phase content.
