Anatrophic nephrolithotomy (ANL) in the selected cases represents the method of choice in the treatment of staghorn calculi. We evaluated postoperative outcome of patients subjected to standard ANL that received 10 mg of Verapamil immediately before declamping renal artery, due to prevention of reperfusion injury. From 2002 to 2005, 18 nephrolithotomies were performed on 15 patients, in the Urology Clinic, University of Sarajevo Clinics Centre. Preoperative evaluation included intravenous urography and radionuclide renal scans which had been repeated 6 months after the operations. 10 males and 5 females were operated with mean age of 45 years. Urography and renal scans showed severe calyceal distortion and infundibular stenosis in 83% cases, complicated with ureteropelvic junction obstruction in 55% cases. Chronic kidney failure was present in 60% patients. Mean operative time was 150 minutes, with mean cold ischemia time of 61 minutes and mean blood loss of 300ml. There were five minor postoperative complications. Residual small calculi were found in 3 patients. Kidney function was stabilized in the patients suffering from chronic kidney failure, which was proved by radio nuclide imaging. ANL improved by using calcium channel blockers as a protective factor for reperfusion injury proved to be a good treatment choice with a low level of complications and noticeable stabilization and improvement of kidneys function.

The aim of this study was to investigate expression of cyclin D1, bcl-2, p53, Ki-67 and HER-2 proteins in 14 cases of non-small cell lung cancer and to establish their correlation to classical clinico-pathological findings, and alleged prognostic value to estimate biological potential of tumor. Retrospective pilot study of the surgically treated non-small cell lung cancer biopsy specimen, paraffin embedded, used immunohistochemical method to demonstrate expression of cyclin D1, bcl-2, p53, Ki-67 and HER-2. Protein quantification was performed by the semi-quantitative method. Achieved results were correlated with classical clinico-pathological parameters, like tumor size, histological type, differentiation level, presence of vascular invasion and metastasis in regional lymph nodes. Out of 14 cases of non-small cell lung cancer, squamous cell carcinoma was found in 7 patients, giant cell carcinoma in 3, adenocarcinoma in 2, and 1 case of pleomorphic and mucoepidermoid carcinoma. Expression of cyclin D1 was not found, while expression of HER-2 and bcl-2 protein was established in one cases each. p53 expression was noted in 8 cases (57,1%). Statistically positive significant correlation (p<0,05) was found among: presence of lymphovascular invasion to tumor tissue and appearance of nodal metastasis; proliferation Ki-67 index and level of tumor differentiation, i.e. size of tumor. Other investigated parameters showed no significant statistically dependence. p53 expression was not correlated to any of the investigated parameters what might imply the possibility that there is an independent pathway of this protein expression. Negative expression of bcl-2 protein points out to possibility that it is not included into process of tumor apoptosis, as well as that proteins cyclin D1 and HER-2 are not included into processes of the tumor genesis. Since the proliferative activity of the tumor, measured by the expression of Ki-67, is correlated to the gradus and size of the tumor mass, Ki-67 protein can be of a prognostic value to determine biological potential of non-small cell lung cancer.

Retrospective study was conducted in surgical intensive care unit (ICU) in Clinical Hospital Center Zagreb in 2005. The aim of study was to create guidelines for empirical antibiotic therapy of sepsis in ICU for unknown causative agent based on antimicrobial susceptibility of causative bacteria. Thirty-two patients with severe sepsis were included in study and from medical records their clinical and microbiological data were analyzed. Antimicrobial susceptibility of the strains isolated from the blood-culture was tested by disk diffusion method according to CLSI (Clinical Laboratory Standard Institution). We used APACHE II score to predict the severity of illness. Mann-Whitney test and chi2 test were used to test statistical significance difference between results. Acinetobacter baumannii and Pseudomonas aeruginosa were the predominant causative agent. Acinetobacter baumannii was displaying excellent susceptibility to ampicillin+sulbactam and carbapenems, whereas Pseudomonas aeruginosa was showed good susceptibility on ceftazidim and carbapenems. Methicillin-resistant Staphylococcus aureus (MRSA), third predominant causative agent exhibiting good susceptibility to vancomycin and linezolide. The recommended therapy is empirical antibiotic therapy and should cover all important pathogens.

Lung cancer is responsible for 40% mortalities from malignant diseases in man and exhibits an extremely infiltrating way of growing. It does not respect the lobes' or the organs' borders and spreads by blood system, lymph system and per continuitatem. According to its biological characteristics and response to treatments it may be divided in to small cell lung cancer (SCLC) and non small cell lung cancer (NSCLC), which also includes other histological types. Lung cancer treatment includes surgical treatment, chemotherapy, radiotherapy, the combination of the former three as well as symptomatic treatment. In this study, we analyzed 125 patients with lung cancer, that were hospitalized at the Clinic for Thoracic Surgery in KCU Sarajevo. The difference according to gender is statistically significant because we had 111 (88,8%) male patients in comparison with 14 (11,2%) female patients. The average age of male patients was 60,3 years while female patients were 61,9 years old on average. Thus, the difference in average age is not statistically significant. In diagnostic procedures: chest radiography was the most significant in peripheral lesions (60, 8%). CT of the thoracic organs has a statistical significance because the tumor changes were confirmed in 123 patients (98,4%). In bronchoscopy, we had 120 patients (96,0%). The number of patients with preformed lobectomy (63) is statistically significantly greater in the observed group (125) then the number of patients with other operative procedures preformed. From the postoperative complications we had exitus letalis 2 (1,6%), wound infection 19 (15,2%), and 104 without complications (83,2%). The results of testing the significance of differences according to the cancer types in non small cell lung cancer were planocellular, adenocarcinoma, and macrocellular. Comparing the preoperative staging and operative findings through stages we obtained to the following results: in stage ST0 the deviation was 16,7%, STIA the deviation was 40,1%, STIB the deviation was 16,1%, STIIA the deviation was 11,1%, STIIB the deviation was 12,5%, STIIIA the deviation was 33,33%, STIIIB the deviation was 33, 3%. From the overall number of patients, who were in preoperatively graded stage STIA, operative findings confirmed STIA, which makes the most important statistically significant difference. In 36 patients or 28,8% the status was changed in operative finding. In 89 patients preoperative status or 72,2% remained unchanged following the operation.

The incidence of cardiovascular diseases (CVD) in women, although lower than in men, increases dramatically after the menopause. Diabetes mellitus is a more powerful predictor of CHD risk and prognosis in women than in men. The aim of this study was to promote diet and physical activity (PA) regimen in order to decrease coronary risk in next years in postmenopausal women with impaired glucose tolerance. Methodological approach of this research is to compare data gathered trough prospective and retrospective analysis of anamnestic data, clinical research, diagnostic tests and biochemical parameters of 100 examinees, regarding the glycoregulation, lipid status, body mass indexes, incidence of hypertension, uric acid and fibrinogen level. The SCORE (Systematic Coronary Risk Evaluation) assessment system is derived from a large dataset of prospective European studies and predicts any kind of fatal CVD events over a ten-year period. It was documented that the then year risk of fatal CVD exerted a shift toward the lower percent value in postmenopausal women after proposed diet/PA regimen. In pre-menopausal women the estimated ten year risk of fatal CVD by SCORE was shifted toward the level below 1%. The risk of 15% and above was not documented after diet/physical activity regimen. The prevalence of the atherogenic lipid markers at the beginning and the end of the assay decreased for all investigated lipid parameters in the group of pre-menopausal women what was more than in postmenopausal ones. Presented data indicate that dietary regimen and physical activity are crucial factors in CVD prevention throughout menopause and beyond. Behavioral changes aimed at decreasing food intake and increasing energy expenditure, should be implemented in pre-menopausal period of life.

The aim of this study was to analyze the Transit time flow measurement (TTFM) experience in the first 1000 CABG operations. First 1000 patients had coronary artery bypass grafting (CABG) performed in Cardiovascular Clinic, University Clinical Centre Tuzla, Bosnia and Herzegovina, between September, 1998 and September, 2003. CABG without use of cardiopulmonary bypass (CPB)-(OPCAB) was used as the preferential surgical method both because this method is reported to have equal or better results than CABG with use of CPB (ONCAB), and because of the significant cost savings realized. TTFM was routinely used in all grafts as a quality assurance measure. Criteria for a poor functioning graft were: low mean flow (MF), pulsatility index (PI) above 5 and a poor diastolic flow pattern. When no reversible cause of poor TTFM results were identified the graft was revised. A total of 1394 grafts in OPCAB group and 1478 in ONCAB group were performed. A total of 38 grafts (2,72%) in 37 patients (7,07%) were revised in OPCAB group, and 26 grafts (1,75%) in 26 patients (5,45%) in ONCAB group. 1 patient in OPCAB group needed 2 graft revisions. Graft revisions were more common in OPCAB, but with no significant difference (p=0,1035). The most frequently revised graft was LAD graft in both groups. Although the percentage of grafts revised are relatively low, it is still very important to record TTFM. More than 5% of patients in both groups needed graft revision. Although TTFM does not guarantee that grafts will stay open for a prolonged period of time we certainly believe that grafts that are occluded at the time of surgery will continue to stay occluded. TTFM is especially critical in OPCAB surgery where the technical challenge of grafting is higher then in ONCAB.

The aim of this research was to determine the incidence, risk factors and perinatal outcome of the macrosomic infants (birth weight > or = 4000 g). The retrospective research was performed using a case-control study conducted at Mostar Clinical Hospital. Total of 379 women gave singleton term births to macrosomic newborn in the period from January 1st, 2004 to December 31st, 2005 (observed group). Another 379 singleton normal birthweight term newborns (birth weight < 4000 g, but not small for gestational age), of the same maternal parity and age, who were delivered in the same period, formed the control group. The incidence of macrosomic births was 13, 1%. In the study group, significantly higher number of cases of postdatism (> 42 weeks of gestation) (P<0,001), maternal obesity (prepregnancy BMI> 26 kg/m2) (P<0,001), gestational diabetes mellitus (P=0,033), hypertension (P=0,025) and male infant (P<0,001) were observed. Cesarean delivery (P<0,001), intrapartal complications (cephalopelvic disproportion P<0.001, perineal trauma P=0,042) and newborn birth trauma (clavicular fracture P=0,038, brachial palsy P=0,021) occurred significantly more often in the macrosomic group. There was only one fetal death in the macrosomic group. In the control group there were no cases of perinatal deaths. To conclude, it is important to emphasize the significance of proper diagnosis of fetal macrosomia and management of macrosomic birth, since we have seen a growing number of macrosomic births during the last decades, and have faced a problem of increased risks of adverse perinatal outcome.

The aim of our study was to establish the extent of influence of different psychotropic drugs to brain Beta-endorphins in experimental animals. The study was performed on albino Wistar rats (weight 250 g), treated with different psychoactive drugs. RIA technique was employed for quantification of brain beta-endorphins. Brain beta-endorphins were higher in experiment group treated with trazodone (929 pg/g +/- 44,43; X+/-SD), and dibenzepine (906,63 pg/g +/- 74,06), yet with lower brain content in rats treated with diazepam (841,55 pg/g +/- 68,47), compared to brain beta-endorphins content of control group treated with saline solution (0,95% NaCl) (873,5 pg/g +/- 44,89). Significant differences were obtained comparing brain beta-endorphins of trazodone vs. diazepam treated animals, with diazepam group having lower values (p<0,02). This study showed differences in changes of rat brain beta-endorphins contents when different psychoactive drugs are used. Therefore, we consider that beta-endorphins could be used for evaluation of effects of psychoactive drugs, as a useful parameter in therapy with these psycho-pharmaceuticals.
