This study explores the anatomical relationship between iliac blood vessels and the lower lumbar spine during supine and prone patient positions. The average height of participants was 174.02 cm ± 9.01, while the average weight was 80.38 kg ± 13.48. Body mass index (BMI) analyses showed differences (p = 0.002), with 34.7% classified as normal weight, 53.1% as overweight, and 12.2% as moderately obese. The study examined the distances between iliac arteries and veins in relation to intervertebral anterior and posterior disc contours. Patient positioning significantly affected these measurements at both L4/L5 and L5/S1 levels. The findings highlight the critical influence of body position on anatomical relationships in the context of lower lumbar spine surgery. The study underscores the importance of preoperative awareness of vascular anatomy to prevent iatrogenic lesions during spine surgery, contributing valuable insights for optimizing surgical approaches and minimizing complications in spine surgery, particularly microdiscectomy.

Aim: The primary aim of the study was to determine the incidence of testicular neoplasms in the Zenica-Doboj Canton (ZDC) region for the period from 2019 to 2021. Also, the study aimed to examine the age structure of the affected population, the frequency of testicular neoplasms in all the ZDC cities and municipalities, and the pathohistological characteristics of neoplasms. Material and methods: The study was conducted at the Oncology and Radiotherapy Department of the Zenica Cantonal Hospital. The study period refers to the time interval from January 2019 to December 2021. The study included 37 patients with a verified diagnosis of testicular neoplasm. Results: Arithmetic mean of patients’ age was 33.49 years, while the standard deviation was 12.59. Most respondents, accounting for 40.5%, were aged 26-35 years. The incidence of testicular neoplasms in the ZDC region was 4.2/100,000 per - sons in 2019, 3.08/100,000 persons in 2020, and 3.10/100,000 persons in 2021. Most diagnosed neoplasms (48.6%) were the myxoid type germ cell originating tumors. Conclusion: The incidence of testicular neoplasms in the ZDC was 4.2/100,000 persons in 2019, 3.08/100,000 persons in 2020, and 3.10/100,000 persons in 2021.

Aim To examine a correlation of demographic characteristics of patients, preoperative modality of conservative therapy and timing on the postoperative outcome of patients six months after the operation. Methods A retrospective, non-randomized, clinical study involved 48 patients of different age and gender with a verified diagnosis of cauda equina syndrome (CES). The inclusion criteria were patients with CES caused by discus hernia. Observed research variables were age, gender, affected vertebral level, conservative modalities of perioperative therapy (nonsteroidal anti-inflammatory drugs - NSAIDs and physiotherapy), duration of symptoms, and outcome parameters (motor and sensory function, sphincter function of the urinary bladder and bowel). Results A statistically significant negative correlation was found between age and postoperative outcome (p<0.05). The affected vertebral level was positively correlated with the motor and sensory outcome (p<0.05). A positive correlation between the use of NSAIDs and the outcome was found (R=0.570; p<0.001), as well as a negative correlation with perioperative physiotherapy (R=-0.201; p= 0.001). Postponement of surgery was negatively correlated with outcome variables (p<0.001). Conclusion The results of the study bring new conclusions that were not previously observed. Possible new characteristics associated with the outcome of cauda equina syndrome were determined.

Aim: To present a very rare case of empyema cavuma septi pellucidi. Case report: A 5-year-old male child was admitted to the Department of Infectious Diseases Cantonal Hospital Zenica because of fever (38.30C), headache and vomiting. The patient developed intracranial hypertension as a result of a compressive purulent collection formed due to meningitis between the lamine of the septum pelucidum with consequent intracranial hypertension. Conclusion: The decision regarding the modality of treatment was not easy. We considered that empyema evacuation using the transcallosalinterhemispheric approach allows the complete removal of purulent collection and the placement of drainage, which allows additional emptying of the empyema cavity and prevents empyema recurrence. Empyema evacuation with drainage and antibiotic therapy have shown beneficial results.

Abstract Glioblastoma, also known as glioblastoma multiforme, is an aggressive type of cancer that is made up of abnormal astrocytic cells, but also contain a mixture of different cell types (including blood vessels) and areas of necrosis. It is often seen in the brain and spinal cord, but glioblastomas are rarely found in the third ventricle. In this case, it was diagnosed in a 22-year-old male patient and we intended to draw attention to its atypical localization and surgical access to this third ventricle glioblastoma.

Background: EMVI is a direct invasion of a vein by a tumor. As a predictor of hematogenous metastasis, it is a poor prognostic factor in rectal cancer and can be accurately identified on MRI prior to surgical procedure. Objective: To evaluate the role of contrast-enhanced T1-weighted magnetic resonance imaging (CET1WI) in addition to high-resolution T2-weighted imaging (HRT2WI) in assessing extramural venous invasion (EMVI) of rectal cancer. Methods: In all 195 patients with rectal cancer, HRT2WI and CET1WI sequences were produced within pre-operative MRI for the purpose of assessing for the presence of EMVI (mrEMVI). CET1WI sequences were produced following administration of Gadolinium contrast medium. mrEMVI assessment results were classified into two groups. Group A consisted of mrEMVI assessment results obtained using HRT2WI sequences only. Group B consisted of mrEMVI assessment results obtained using a combination of HRT2WI + CET1WI sequences. Results obtained for each group (A and B) were correlated with a histopathological finding (pEMVI) as a reference standard. Results: Out of a total of 195 rectal cancer patients, mrEMVI was positive in 41 (21%) patients in group A, and in 45 (23%) patients in group B. Histopathological finding demonstrated pEMVI in 54 (27.7%) patients. A statistical analysis of group A (HRT2WI sequences) resulted in 75.9% sensitivity to mrEMVI and 96.4% specificity, Positive Predictive Value of 89.1% and Negative Predictive Value of 91.2% (95% confidence interval (CI), p< 0.05). Statistical analysis of group B (HRT2WI + CET1WI sequences) resulted in 83.3% sensitivity to mrEMVI and 98.5% specificity, Positive Predictive Value of 89.1% and Negative Predictive Value of 91.2% (CI 95%, p< 0.05). Conclusion: T1-weighted magnetic resonance imaging (CET1WI) in addition to high-resolution T2-weighted imaging (HRT2WI) increased evaluation of extramural venous invasion (EMVI) of rectal cancer.

The HERe2Cure project, which involved a group of breast cancer experts, members of multidisciplinary tumor boards (MTB) from health-care institutions in Bosnia and Herzegovina, was initiated with the aim of defining an optimal approach to the diagnosis and treatment of HER2 positive breast cancer. After individual multidisciplinary consensus meetings were held in all oncology centers in Bosnia and Herzegovina, a final consensus meeting was held to reconcile the final conclusions discussed in individual meetings. Guidelines were adopted by consensus, based on the presentations and suggestions of experts, which were first discussed in a panel discussion and then agreed electronically between all the authors mentioned. The conclusions of the panel discussion represent the consensus of experts in the field of breast cancer diagnosis and treatment in Bosnia and Herzegovina. The objectives of the guidelines include the standardization, harmonization, and optimization of the procedures for the diagnosis, treatment, and monitoring of patients with HER2-positive breast cancer, all of which should lead to an improvement in the quality of health care of mentioned patients. The initial treatment plan for patients with HER2-positive breast cancer must be made by a MTB comprised of at least: A medical oncologist, a pathologist, a radiologist, a surgeon, and a radiation oncologist/radiotherapist.

Aim To analyse potential clinical implications of the distance between large retroperitoneal vessels and lower segment of the lumbar spine in the supine and prone position. Methods Prospective, non-randomised study included 40 patients of different age and gender. For all patients magnetic resonance imaging of the lumbar spine was performed in supine and prone position. The level of aortal bifurcation, common iliac vein confluence, the distance from the anterior and posterior aspect of the annulus to the posterior wall of the large retroperitoneal vessels were analysed. Results The study included 40 patients, 22 (55%) males and 18 (45%) females. The level of aortal bifurcation was higher in prone compared to supine position (χ2 = 29.88571; p<0.05). In supine and prone positions, the common iliac veins confluence was most commonly at the level of the lower third of the L4 vertebra (p>0.05). There was a statistically significant difference between the distance from the left common iliac artery to the anterior contour of L4/L5 intervertebral disc (p<0.05). Conclusion Knowledge of the anatomic relationship between iliac vessels and structures of the lower segment of the lumbar spine is very important in the prevention of a potentially severe complication, such as artificial common iliac vessels rupture. Our study showed that the risk of lesions of the common left iliac artery was lesser in the prone position.

SUMMARY The aim of the study was to analyze correlation between morphological characteristics of intracranial meningiomas and Ki67 labeling index (Ki67 LI), and their influence on peritumoral brain edema (PTBE). There were 41 consecutive patients with intracranial meningiomas surgically treated at the Department of Neurosurgery, Zenica Cantonal Hospital, Zenica, Bosnia and Herzegovina, during the period from January 2010 to December 2015. We reviewed clinical data including patient age, gender, magnetic resonance imaging (MRI) characteristics of the tumor and peritumoral edema, tumor margins, intraoperative characteristics, histopathologic grade and Ki67 LI. In all cases, follow up MRI was obtained at about three months after resection and PTBE was analyzed. Our research showed the tumor volume, tumor margins, and intraoperative signs of arachnoidal and pial invasion to be associated with PTBE in intracranial meningiomas. Ki67 LI expression correlated with PTBE. This study showed the resolution of PTBE to depend on invasive behavior of meningioma and KI67 LI. PTBE, pial/cortical and arachnoidal invasion significantly influence the extent of surgical resection.

Aim To determine capabilities and potential of contrast enhanced magnetic resonance imaging (MRI) enterography in order to establish the diagnosis and to evaluate severity and activity of intestinal inflammation. Methods Fifty-five patients with suspicion for presence of Crohn's disease were evaluated. All patients underwent contrast enhanced MRI enterography and diffusion weighted imaging (DWI), and subsequently endoscopic examination or surgical treatment. Four parameters were analysed: thickening of the bowel wall, and presence of abscess, fistula and lymphadenopathy. Results Comparing results of DWI and contrast enhanced MRI enterography a significant difference between results given through diffusion and histopathological test was found, e.g. a significant difference between results obtained through diffusion and MRI enterography was found. MRI enterography sensitiveness for bowel wall thickening was 97.7% and specificity 70%, whilst DWI sensitivity for bowel wall thickening was 84% and specificity 100%. The diagnostics of abscess and fistula showed no significant difference between DWI and MRI, while in lymphadenopathy significant difference between contrast enhanced MRI enterography and DWI was found. Conclusion Contrast enhanced MRI enterography in combination with DWI allows for excellent evaluation of disease activity, but also problems or complications following it. The examination can be repeated, controlled, and it can contribute to monitoring of patients with this disease.
