Introduction: Pancreatic injuries are not common after blunt and penetrating trauma, but can be challenging to diagnose and manage. Case report: Twenty-three year old man, injured during a fall from a motorcycle two days earlier, was admitted to Department of Surgery, University Clinical Centre Tuzla because of suspicion of pancreatic trauma. Immediately after hospitalization, patient underwent laboratory and radiological tests that revealed the existence of pancreatic trauma, so we opted for urgent surgical treatment. Surgery and early postoperative course were normal and the patient was discharged on the ninth postoperative day. Conclusion: Proper diagnosis and well-selected surgical treatment significantly increases the chances for recovery of these patients.

Although laparoscopic cholecystectomy has become a gold standard in treatment of symptomatic cholelithiasis, it is associated with higher risk of intraoperative lesions and primarily lesions of biliary ducts. In small percentage of cases biliary fistulas occur, most commonly after leakage from cystic duct stump or accessory bile ducts – Luschka’s duct. We report of a patient who had episodes of abdominal pain following routine laparoscopic cholecystectomy for acute calculous gallbladder. Results of conducted diagnostics verify the presence of biliary fistula caused by obstruction of bile pathways by stagnant pus and microcalculi of common bile duct, with development of biloma presumably caused by pressure injection of contrast material during ERCP procedure. Endoscopic sphincterectomy via ERCP enabled healing of formed biliary fistula, whilst continuous percutaneous ultrasound guided drainage of biloma was method of choice in later treatment of our patient. It is important to note that diagnostic evaluation of biliary fistula is very challenging and that timely nonsurgical treatment is of great benefit for patient.

Introduction: Acute kidney injury is characterized by a rapid loss of renal excretory function with the increase of nitrogen compounds in the blood and with different outcome. Objective: Since descriptions of the risk factors and sequelae of acute kidney injury (AKI) remain relatively limited, the objective of this study was to determine etiology and clinical characteristics of AKI, as well as risk factors for adverse outcome of renal function and death in AKI patients. Methods: We retrospectively studied a cohort of 84 adult AKI patients admitted to Nephrology Clinic in University Clinical Centre Sarajevo during period 2012-2014. Demographic, laboratory and clinical parameters were retrieved. The in-hospital and 6 months mortality were recorded. Renal function outcome was defined 3 months following discharge. Results: Majority of patients were older (median age 73.5 years) with great severity of AKI (Stage III in 78.5% of cases) and high burden of comorbidities (mean Charlson comorbidity index, CCI score 6.4±3.05). The most common causes of AKI were acute interstitial nephritis (16.7%), heart failure (15.5%), gastroenterocolitis (13.1%), and sepsis (12%). Renal function recovery was recorded in 48.8% of patients, with prevalence of 10.7% of intrahospital mortality and 37.3% of 6 months mortality. Risk factors for poor outcome of renal function and mortality in AKI patients were increasing age and higher CCI score, while protective factor was higher diuresis. Sepsis proved to be risk factor for death.

Aim: The aim of the research was to compare the relationship between inflammatory biomarkers and procoagulants with kidney function assessed by using cystatin C, serum creatinine, and eGFR and determine the sensitivity of cystatin C, serum creatinine and eGFR to total cardiovascular morbidity in patients with CKD stages 1-4. Methods: The research included 120 patients older than 18 years with CKD stages 1-4 monitored over a period of 24 months. Results: Serum cystatin C correlates with fibrinogen (p<0.01), serum albumin (p<0.01), D-dimer (p<0.05), antithrombin III (p<0.01) strongly in relation to the evaluation of kidney function based on serum creatinine and eGFR. By following cystatin C, creatinine and eGFR with comparison of ROC to total cardiovascular morbidity, the highest sensitivity in relation to the presence of cardiovascular morbidity shows cystatin C, then eGFR and the lowest, creatinine, with a significant difference between cystatin C and serum creatinine (p<0.05). Conclusion: Serum cystatin C is more strongly correlated with some biomarkers (fibrinogen, serum albumin, D-dimer, antithrombin III), while simultaneously showing a stronger sensitivity in relation to total cardiovascular morbidity compared with the assessment of kidney function based on serum creatinine and eGFR.

Introduction: Accommodative Convergence/Accommodation (AC/A) ratio is constant at one and the same person in the course of life, i.e. the same ratio accommodative convergence monitor any change in accommodation measured in diopters. Such a perfect relationship is possible if there are no refractive anomalies in both eyes and oculomotor imbalance of eye muscles. Material and methods: We are examined 50 patients with close brain injury, and patients which had problems with near vision, accommodation and convergency were reducted, with loss motor fussion, and preserved stereoscopis vision, and showed us, that disturbances are clear motor and folowed with incapable of patient to hold of superposition view to watching object. Results: The difference in average proximity distance vision and reading time with no fatigue after 6 months a statistically significant, the value of t-test, t = 1873 for p <0.01, r = 0. 718. The value of convergent fusion 6 months after treatment in 30% of the patients was from 0 to16 Pd, S. D. = 18. 6, and χ2 = 7. 22. In 18% of the patients was from 0 to 10 Pd, S. D = 17. 61, and χ2 = 5. 41, at 20% of patients 0 to 22 Pd, SD = 14. 18, χ2 = 6. 84, in 16% of patients 0 to 4 Pd, SD = 16. 41, χ2 t-test = 5. 13 and the remaining 16% of patients the value of convergent fusion is about 1 PD, S. D = 15. 01, χ2 t = 5. 18. All patients showed significant improvement in near vision compared to the value of convergent fusion before treatment where χ2 t-test = 9.41, after 6 months of treatment, there is considerable significance p < 0 01, t–test 0. 914, correlation coefficient r = 0. 881. Conclusion: Disturbances of AC / A ratio should be evaluated only with regard to all symptoms and is only possible by proper rating interference in reading.

Introduction: Traumatic injuries of the eye are the most common cause of loss of visual function. In our study we performed Ocula Trauma Score (OTS). We compared with the values of visual acuity of injury and thus get an accurate model for determining the prognostic value of the final visual acuity before treatment of the patient. This model is a reliable test for both the ophthalmologist and the patient. Aim of study: The aim of this study was to show the socioepidemiological and demographic profile, as well as the most common mechanism in ophthalmic injuries, so to determine the final visual acuity and assessment and evaluation of sensitivity and specificity of ocular trauma score (OTS), and most importantly to determine the prognostic value final visual acuity after eye injuries. Material and Method: We conducted a clinical-epidemiological, retrospective-prospective study at the Department of Ophthalmology, Clinical Centre University in Sarajevo in the period 2009-2011. A sample of 124 patients with diagnosed closed of eye injuries were recruited. We applied Classifying Closed Globe Injury, performed Calculating the OTS and convert of total raw points into % chance of vision outcomes. Results: Comparison of age groups by gender shows that there is no statistically significant (x2 = 5.155; p = 0.2718). Of the total number of closed eye injuries (N = 124) at the admission from groups D and E with the worst vision were 29 patients (23.38%), in group C had low visual acuity of 20 (16.12%), in group B the mean visual acuity 33 (26.61%), and in group A well-preserved visual acuity 42 (33.87%) patients. On the demission patients with well-preserved visual function was 84 (67.74%), with a medium of visual function 10 (80.64%), while the poorer visual function was 4 (3.225%) and 7 (5.645%) patients had a sense of light and projections and 1 (0.8%) patient had lost visual acuity-amaurosis. 18 (14:51%) patients did not take their eyesight due to a fresh post-operative recovery. Conclusion: Data on each patient are based on the possibility of such characteristics of the mechanism of injuries presentation of vision at the beginning of disease, injury and zones relative afferent pupillary defect possibility assumptions what will be with the vision postoperatively.

Goal: This study aimed to investigate the differences in values of K1 and K2 readings, the central corneal thickness (PAH) before the collagen crosslinking procedure (CXL) and 3, 6, 12 months later. Methods: 64 eyes were evaluated in retrospective cross sectional study. The corneal biomechanical parameters were taken with WaveLight Allegro Oculyzer produced by Alcon before the CXL, 3,6, 12 months after the procedure. The curvature of K1 reading and K2 reading were taken and the central corneal thickness were considered due to the time after CXL. Results: The value of K1 reading before the treatment was 48.8 diopters (D) (46.65-50.50) and was statistically significant lower comparing to the value of K1 3 months after the collagen CXL procedure 46.30 D (43.57-49.45) (p=0.0006), K1 reading one year post collagen CXL procedure was 47.20 D (44.35-50.07) (p=0.002). The value of K2 reading before the collagen CXL procedure was 52.65 D (47.55-54.72), 3 months after the procedure was 51.4 (45.05-54.0), 6 months later 48.55 D (47.20-50.62), 12 months later 51.30 D (47.22-54.77). There is statistically significant lower value of K2 reading 6 months after the treatment comparing to the values 3 months postoperatively (p=0.014). However there is significantly lower values of K2 reading 12 months postoperatively comparing to preoperative period (p=0.006). The value of central corneal thickness preoperative was 431.0 microns (398.0-446.25), 3 months after collagen CXL procedure was 373.50 microns (363.25-430.75), 6 months later 435.0 microns (360.0-464.75), 12 months after the CXL procedure was 429.50 microns (357.75-496.25). There is statistically significant lower values of central corneal thickness 3 months after collagen CXL treatment comparing to the central corneal thickness preoperative (p<0.005). There is statistically significant lower values of pachymetry 12 months after the CXL procedure comparing to the values 6 months later (p=0.036) and those preoperativelly (p=0.032). There is no statistically significant difference in the values of central corneal thickness in the period from 3 and 6 months postoperatively. Conclusion: After riboflavin-UVA CXL in eyes with keratokonus there was significant decrease in central corneal thickness 3 and 6 months after the procedure and the thickness is almost the same 12 months. However, K2 (Kmax) reading is significantly changed 3 and 6 months later and is followed by changing of K1 reading.

BACKGROUND/AIM In prostate tumors, angiogenesis, measured as microvessel density, is associated with tumor stage and Gleason score. The aim of this study was determine neovascularization of prostatic adenocarcinomas in core biopsies and corresponding prostatectomies. METHODS The study population included 61 patients who underwent radical prostatectomy (RP) for localized prostate carcinoma patients and did not receive chemohormonal, or radiation therapy before surgery. Tumor blocks were immunostained using the endothelial-specific antibody CD31 and subsequently evaluated at x 400 magnification in both biopsies and corresponding prostatectomies. RESULTS When comparing microvessel density in core biopsies and corresponding prostatectomies, no statistically significant difference was found (p > 0.1). A statistically significant positive correlation was found when determining correlation between microvessel density (as linear and categorical variable, i.e., with the cut-off value of 48) that was associated with the Gleason score (p < 0.05) and tumor stage (p < 0.0001). There was no correlation between microvessel density and preoperative values of serum prostate-specific antigen (PSA) (p > 0.1). CONCLUSION Microvessel density can be reliably applied to needle prostate biopsy specimens. Quantification of the microvascular density in biopsies is an accurate pre-operative predictor of tumor stage, discriminating between organ-confined and organ-extending neoplasms.
