Long-term treatment outcomes of spinal intradural tumors: A 10-year cohort study in Zenica-Doboj Canton
No full textIntroduction: Despite the presence of various constraints, Bosnia and Herzegovina has managed to establish healthcare services in the field of spinal surgery. Limiting factors associated with resource scarcity and a shortage of neurosurgeons may pose challenges, but they are not insurmountable in the context of spinal tumor surgery. This study aims to provide a comprehensive 10-year analysis of intradural spinal tumors in resource-constrained healthcare settings and assess surgical outcomes in these challenging environments.
Methods: A retrospective study was conducted involving 39 patients with intradural spinal tumors in Zenica-Doboj Canton, Bosnia and Herzegovina, from 2011 to 2021. Patients underwent neurological examinations and spinal magnetic resonance imaging scans, followed by post-surgery assessments at 3 and 6 months using the McCormick scale.
Results: Among the 39 patients, tumor distribution was as follows: meningioma (15, 38.5%), ependymoma (3, 7.7%), schwannoma (11, 28.2%), neurenteric cyst (1, 2.6%), primary melanoma (2, 5.1%), lipoma (1, 2.6%), and metastasis (6, 15.4%) (p < 0.001). A majority of patients reported localized and radicular pain (37, 94.9%, p < 0.001) and paresthesia (33, 84.6%, p < 0.001). Motor weakness was noted in 20 (51.3%) patients, while sphincteric dysfunction was reported by 17 (43.6%) patients. The average symptom duration was 397.9 ± 380.9 days, ranging from 14 to 1460 days (p < 0.001). Pneumonia and liquorrhea were reported by 1 (2.6%) patient each. Regarding mortality, 1 (2.6%) patient passed away within a 6-month follow-up period (p < 0.001), and 2 (5.1%) patients were diagnosed with primary malignant melanoma. Significant improvements in McCormick scores were observed between postoperative and 3-month assessments (p < 0.001) and between 3-month and 6-month assessments (p = 0.024).
Conclusions: This study offers valuable insights into the management of intradural spinal tumors in resource-constrained healthcare settings. Timely diagnosis and surgical intervention are essential for achieving positive patient outcomes in these challenging environments
Endocarditis lenta-patient survived septic shock: a case report
No full textInfective endocarditis is defi ned as an infection of the endocardial surface of the heart. Its intracardiac effects include severe valvular insuffi ciency, which may lead to intractable congestive heart failure and myocardialabscesses. This disease still carries a poor prognosis and a high mortality.A severe case of infective endocarditis with its complications is presented. A man with aortic prosthetic valve due to earlier aortic stenosis and corrected aortal coarctation and implanted pacemaker presentedwith prolonged unexplained fever, malaise, sweating, weight loss (15 kg/4 months) and lumbar pain. He was treated with broad-spectrum antibiotics prior IE diagnosis was considered. Echocardiogram showedaortic vegetations and possible periaortal abscess formation. Nonspecifi c infl ammation parameters were high positive. Cultures were constantly negative. His condition had deteriorated suddenly, and he had presentedwith worsening of cutaneous vasculitis, subacute glomerulonephritis and subsequent acute respiratory distress syndrome and septic shock. This patient survived with residual bilateral necrosis of the feet andtoxic peroneal paresis. At the end transthoracic echocardiogram showed enlarged heart chambers, LV mild dilated and concentric hypertrophy with ejection fraction about 40%, degenerative postinfl ammatory mitralvalve changes, mild mitral regurgitation and tricuspid regurgitation, postinfl ammatory aortic root fi brosis and moderate aortic valve stenosis (AVPG max 50,9 mmHg, AVPG mean 24 mmHg) with no pericardial effusion. Initial suspicion of Q fever was defi nitely excluded by serological testing showing nonspecifi c IgM positivity,probably rheumatoid factor related
Gender-related epidemiological characteristics of cauda equina syndrome caused by disc herniation: a 10-year study in Zenica-Doboj Canton, Bosnia and Herzegovina
No full textIntroduction: The unrecognized cases of cauda equina syndrome (CES) and the lack of epidemiological data in Bosnia and Herzegovina about this neurosurgical emergency, including the Zenica-Doboj Canton, contribute to the lack of awareness among health-care professionals, potentially leading to delayed diagnosis and referral for surgical decompression. Aim of this study is to analyze gender-related epidemiological characteristics of CES in Zenica-Doboj Canton in 10 years period.
Methods: The study was conducted in the Zenica-Doboj Canton, and data were obtained from the time period between 2012 and 2022. The study included a total sample of 1709 patients diagnosed with disc herniation who underwent surgical decompression. In total, 48 patients developed CES.
Results: The analysis unveiled noteworthy gender disparities, with male predominance (79.2% vs. 20.8%, p < 0.001) and varying employment distributions (males: 23.7% unemployed, 63.2% employed, 13.1% retired; females: 40.0% unemployed, 20.0% employed, 40.0% retired, p < 0.001). The calculated OR for 2012-2022 was 2.969 (95% CI: 1.576-5.593), signifying a substantial gender-incidence relationship for CES. CES-I incidence ranged 0.80–1.60/100,000 and CES-R ranged 0.25-0.83/100,000. Highest CES incidence was 4.17/100,000 (2015); the lowest was in 2019 with no CES-R cases reported. Male incidence peaked at 2.64/100,000 (2018), and the lowest was 1.06/100,000 (2013, 2017). For females, the highest was 1.17/100,000 (2018, 2021), with no cases reported in certain years. The affected level demonstrated gender differences, with L4/L5 prevalence in males (47.4%) and L3/L4 in females (50%, p = 0.165).
Conclusion: This study revealed a higher incidence of CES in males compared to females in the Zenica-Doboj Canton. The heterogenicity of data regarding CES occurring due to the lumbar disc herniation is significant. This indicates a clear need for additional research and epidemiological studies that would highlight the population of patients that have a higher risk of CES onset
Clinical and radiologic features in patients with the WHO grade I and II meningiomas
No full textIntroduction: Meningiomas are the most common benign tumor of the central nervous system, accounting for 53.3% and 37.6% of all central nervous system tumors (1). The World Health Organization (WHO) Grade I meningiomas account for 80.5% of all meningiomas and are considered benign meningiomas; the WHO Grade II meningiomas account for 17.7% of all meningiomas and exhibit more aggressive behavior.
Methods: In the period 2015-2022, a retrospective single-center study at the clinic of neurosurgery at the Clinical Center University of Sarajevo was conducted, which included patients with a pathohistological finding of WHO Grade I or II meningioma. Depending on the pathohistological grade of the tumor, patients were divided into two groups: Grade I and Grade II patients. Patients were examined clinically and radiologically. Clinical data collected included in the study: Gender, age, number of symptoms before surgery, whether patients were symptomatic or asymptomatic, pre-operative Eastern Cooperative Oncology Group,and Karnopsky performance scale. Pre-operative contrast magnetic resonance imaging of the head measured tumor volume, temporal muscle thickness (TMT), sagittal midline shift, and surrounding cerebral edema.
Results: A total of 80 patients were enrolled in the study, 68 with WHO Grade I and 12 with WHO Grade II meningiomas. We found that patients with Grade I meningioma were younger and that the mean thickness of the temporal muscle was statistically thicker than in patients with Grade II. Increasing TMT was significantly and positively associated with Grade I tumors and negatively associated with Grade II tumors (p = 0.032).
Conclusion: This study demonstrates that TMT can serve as a radiologic pre-operative indicator of meningioma grade and provide valuable guidance to neurosurgeons in surgical planning. Further studies are needed to validate these results
Current Management of Mirror Distal Anterior Cerebral Artery Aneurysms in Association with Multiple Aneurysms: Case Report with Literature Review
No full textTime Course of Symptoms in Normal-Pressure Hydrocephalus: A Systematic Review
No full textBackground and Objectives: Idiopathic normal-pressure hydrocephalus (NPH) is a treatable, but diagnostically challenging condition in the elderly marked by gait disturbance, cognitive decline, and urinary incontinence. Ventriculoperitoneal (VP) shunting is effective, but the prognostic significance of symptom duration before surgery remains unclear. This systematic review evaluates symptom duration in NPH patients with postoperative outcomes. Methods: A systematic search of PubMed, Scopus, and Embase was conducted per PRISMA guidelines. Studies were included if they assessed clinical or radiological outcomes of VP shunting in adult NPH patients, reported symptom duration, and had a follow-up of at least one month. Clinical outcomes (MMSE, TUG, NPH score) were qualitatively analyzed due to study heterogeneity. Results: Twenty-four studies comprising 1169 patients were included (mean age: 72.45 years; mean symptom duration: 33.04 months). Most studies reported clinical improvement after VP shunting. However, few directly evaluated the effect of symptom duration, yielding inconsistent findings: some suggested better outcomes with shorter symptom duration, while others found no clear correlation. Larger studies often lacked conclusive data, and no randomized controlled trials were identified. Conclusions: VP shunting remains an effective intervention for NPH; however, evidence supporting the predictive value of preoperative symptom length is inconclusive. This review highlights the need for standardized diagnostic protocols and larger prospective studies to clarify this association and optimize surgical timing

Augmented Reality Integration in Skull Base Neurosurgery: A Systematic Review
No full textBackground and Objectives: To investigate the role of augmented reality (AR) in skull base (SB) neurosurgery. Materials and Methods: Utilizing PRISMA methodology, PubMed and Scopus databases were explored to extract data related to AR integration in SB surgery. Results: The majority of 19 included studies (42.1%) were conducted in the United States, with a focus on the last five years (77.8%). Categorization included phantom skull models (31.2%, n = 6), human cadavers (15.8%, n = 3), or human patients (52.6%, n = 10). Microscopic surgery was the predominant modality in 10 studies (52.6%). Of the 19 studies, surgical modality was specified in 18, with microscopic surgery being predominant (52.6%). Most studies used only CT as the data source (n = 9; 47.4%), and optical tracking was the prevalent tracking modality (n = 9; 47.3%). The Target Registration Error (TRE) spanned from 0.55 to 10.62 mm. Conclusion: Despite variations in Target Registration Error (TRE) values, the studies highlighted successful outcomes and minimal complications. Challenges, such as device practicality and data security, were acknowledged, but the application of low-cost AR devices suggests broader feasibility
Lower urinary tract symptoms (LUTS) as a clinical feature of lumbar spinal stenosis (LSS): a prospective study with lumbar spine morphometry analysis
No full textAim To investigate clinical and morphometric characteristics of patients with lower urinary tract symptoms (LUTS) due to lumbar spinal stenosis (LSS).Methods This study evaluated LSS patients using clinical assessments of motor, sensory, bladder, and bowel functions, and functional disability scores from the Oswestry Disability Index (ODI) and Swiss Spinal Stenosis Questionnaire (SSSQ). Morphometric analysis included MRI measurements of the anteroposterior diameter of the intervertebral disc and dural sac, and the modified Torg-Pavlov ratio (mTPR), with follow-up re-evaluations at 6 months.Results Of 159 patients, 49 (30.8%) had LUTS and 110 (69.2%) were in the control group. LUTS patients had a significantly higher prevalence of neurogenic claudication (100% vs. 47.3%; p<0.001), lower back pain (93.9% vs. 77.3%; p=0.011), and lower extremity pain (57.1% vs. 34.5%; p=0.008). The LUTS group also had higher ODI (54.0 vs. 50.0; p=0.019) and SSSQ score (44.0 vs. 34.0; p<0.001). Morphometric analysis showed significantly lower mTPR in LUTS patients (median 0.31 vs. 0.45; p<0.001), with an AUC of 0.704 (95%CI 0.627-0.774). mTPR≤0.31 predicted surgical revision within 6 months (OR:3.4, CI: 1.2-9.8), motor deficiency (OR:2.1, 95%CI: 1.4-5.2), and persistent LUTS post-surgery (OR:4.5, 95%CI: 1.1-18.9). mTPR≤0.34 was associated with worse follow-up outcome, including increased ODI (β:3.2; 95%CI: 1.1-5.3; p=0.004) and SSSQ score (β:4.8; 95%CI:2.1-7.5).Conclusion LUTS patients with LSS exhibit more severe symptoms and poorer outcome, with mTPR≤0.34 being a predictor of adverse clinical outcome and the need for surgical revision within 6 months
