    Improving glioma resection with 2D-intraoperative ultrasound: Observational results and systematic literature correlation

    by Octavian Mihai Sirbu, Alin Vasile Chirtes, Lucian George Eftimie, Andreea Plesa, Marian Mitrica, Mircea Radu Gorgan

    Background: Maximizing tumor resection is a key prognostic factor in glioma surgery. Intraoperative cerebral ultrasonography (IOUS) offers real-time, cost-effective guidance that can enhance the extent of resection (EOR) and gross total resection (GTR) rates, but data remain heterogeneous. Methods: We conducted a retrospective analysis of a prospective observational database including patients with gliomas undergoing surgery with or without IOUS guidance in one tertiary neurosurgical center. Inclusion criteria were preoperative magnetic resonance imaging-suspected gliomas, intended GTR, and available early postoperative imaging. Outcomes were compared using propensity score matching. In addition, a systematic literature review covering 2018–2024 was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: A total of 38 patients were included after matching, with 19 patients in each group. IOUS use significantly improved the mean EOR (85.0% vs. 66.2%, P = 0.028) and GTR rate (47.4% vs. 10.5%, P = 0.029). Benefits were more pronounced in tumors larger than 10 cm 3 . A learning curve effect was observed, with increasing resection rates over time. The literature review identified nine relevant studies, with GTR rates ranging from 42% to 91%, and recent studies showing improved outcomes with advanced IOUS techniques. These findings should be interpreted cautiously given the small sample size and single-center design. Conclusion: IOUS significantly enhances resection outcomes in glioma surgery and demonstrates a progressive benefit with surgeon experience. Given its versatility, low cost, and growing integration with technologies such as contrast-enhanced ultrasound and artificial intelligence, IOUS remains a fundamental tool in modern neurooncology. Future multicenter prospective studies are needed to standardize its use and assess long-term patient outcomes.

    Multidisciplinary Management of an Atypical Gigantic Sciatic Nerve Schwannoma: Case Presentation and Systematic Review

    by Octavian-Mihai Sirbu, Mihai-Stelian Moreanu, Mark-Edward Pogarasteanu, Andreea Plesa, Mihaela Iordache, Teofil Mures, Anca Maria Sirbu, Marius Moga, Marian Mitrica

    Background: Sciatic nerve schwannomas are rare benign tumors that can develop along the nerve’s course, from the pelvis to the thigh. Giant schwannomas, defined as those exceeding 5 cm, are particularly rare and may alter the tumor’s anatomical relationship with the nerve, impacting surgical strategy. Methods: A PRISMA 2020-compliant systematic review was conducted using the terms (“sciatic” AND “schwannoma”) for publications from 2000 to October 2024. Of 166 identified articles, we excluded those lacking giant schwannoma cases or involving syndromic associations. We also report a novel case from our center. Results: Our patient, a 35-year-old woman, presented with tingling and discomfort while sitting, localized to the left thigh, without radicular pain or motor deficits. MRI revealed a 14 × 7 cm mass. This is, to our knowledge, the first reported case of a giant solitary sciatic schwannoma of these dimensions located exclusively in the thigh, resected via intracapsular dissection with nerve monitoring, that was fully documented and reported. The review yielded 22 relevant articles, most involving pelvic or pelvic–thigh junction locations, with low recurrence rates. Conclusions: Giant sciatic schwannomas may be asymptomatic and slow-growing. This case is notable for tumor’s location, large size, and successful nerve-sparing surgical outcome.

    Immunogenetics of Multiple Sclerosis in Romanian Patients: Preliminary Data

    by Alexandra Elena Constantinescu, Ion Mărunțelu, Andreea Pleșa, Carmen Adella Sîrbu, Florentina Cristina Pleșa, Andreia Ioana Constantinescu, Ileana Constantinescu

    Multiple sclerosis (MS) is a chronic autoimmune disease characterized by the immune system attacking the central nervous system, leading to demyelination and neurodegeneration. This work investigates the relationship between specific human leukocyte antigen (HLA) polymorphisms and MS, aiming to reveal the immunogenetic background of this disease for more individualized management approaches. This study employed a case–control design, analyzing HLA allele frequencies in 179 MS patients and 200 control subjects using next-generation sequencing, The key findings indicate significant associations between several HLA Class I and II alleles and MS, including HLA-B*35:03:01:03, HLA-C*04:01:01:14, HLA-DRB1*15:01:01:26, and HLA-DQA1*05:05:01:02. These findings emphasize the critical role of HLA molecules in MS Romanian patients.

    by Florentina Cristina Pleșa, Elena Andreea Arsene, Andreea Pleșa, Săndica Bucurică, Daniela Anghel, Carmen Adella Sîrbu, Monica Marilena Țânțu, Alexandru Andrei Badea, Octavian Vasiliu, Alice Elena Munteanu

    Background and Objectives: This study aims to identify cardiovascular risk factors among 91 patients with multiple sclerosis in Bucharest, Romania, using data from medical records and a self-administered questionnaire. Materials and Methods: The research focuses on smoking status, body mass index, blood sugar, cholesterol, triglycerides, blood pressure, and renal function. The average age of the patients was 42.90 ± 10.60 years, and 74.73% were female. The average BMI was 23.89 kg/m2 ± 4.74 kg/m2 (lower than in the general population), with 41.76% of patients having a BMI outside normal limits. The majority were former smokers (35.87%), followed by non-smokers (28.26%), and the fewest were smokers of more than 20 cigarettes/day (7.61%). The average total cholesterol was 198.48 ± 38.56 mg/dL, triglycerides were 114.22 mg/dL ± 76.2281 mg/dL, and blood glucose was 97.54 ± 36.58 mg/dL. While 25.27% of the patients had fasting blood glucose > 126 mg/dL, only five patients were diagnosed with DM. The average blood pressure was 137.5165 ± 19.5047 mmHg, with only 11 patients diagnosed with HTA. Results: The study found an average cardiovascular risk of 6.6133% ± 7.1412%, with higher values among males, rural patients, those with secondary-progressive MS, and those with a disease progression >10 years (after age adjustment). Conclusions: The study underscores the importance of identifying and combating cardiovascular risk factors in patients with multiple sclerosis.

    The Hidden Heart: Exploring Cardiac Damage Post-Stroke: A Narrative Review

    by Marian Mitrică, Lorenzo Lorusso, Alexandru-Andrei Badea, Carmen-Adella Sîrbu, Andreea Pleșa, Ana-Maria Alexandra Stănescu, Florentina Cristina Pleșa, Octavian Mihai Sîrbu, Alice Elena Munteanu

    Stroke–heart syndrome (SHS), a critical yet underrecognized condition, encompasses a range of cardiac complications that arise following an ischemic stroke. This narrative review explores the pathophysiology, clinical manifestations, and implications of SHS, focusing on the complex interplay between the brain and the heart. Acute ischemic stroke (AIS) triggers autonomic dysfunction, leading to a surge in catecholamines and subsequent myocardial injury. Our review highlights the five cardinal manifestations of SHS: elevated cardiac troponin (cTn) levels, acute myocardial infarction, left ventricular dysfunction, arrhythmias, and sudden cardiac death. Despite the significant impact of these complications on patient outcomes, there is a notable absence of specific guidelines for their management. Through a comprehensive literature search, we synthesized findings from recent studies to elucidate the mechanisms underlying SHS and identified gaps in the current understanding. Our findings underscore the importance of early detection and multidisciplinary management of cardiac complications post-stroke. Future research should focus on establishing evidence-based protocols to improve clinical outcomes for stroke patients with SHS. Addressing this unmet need will enhance the care of stroke survivors and reduce mortality rates associated with cardiac complications.

    by Andreea Pleșa, Florina Anca Antochi, Mioara Laura Macovei, Alexandra-Georgiana Vîrlan, Ruxandra Georgescu, David-Ionuț Beuran, Săndica Nicoleta Bucurica, Carmen Adella Sîrbu, Any Axelerad, Florentina Cristina Pleșa

    Background/Objectives: This study investigated the frequency and timing of optic neuritis (ON) episodes in relation to the onset of multiple sclerosis (MS) and examined the occurrence of Uhthoff’s phenomenon and Lhermitte’s sign to understand their roles in early diagnosis and disease progression. Methods: A longitudinal study was conducted with 127 MS patients. Clinical data, including ophthalmological examinations for ON, were collected and questionnaires assessed the presence of Uhthoff’s phenomenon and Lhermitte’s sign. Results: Results showed that 37% of patients experienced demyelinating retrobulbar ON, with 25.53% having ON as the initial symptom of MS. Residual visual acuity impairment (below 20/40) and dyschromatopsia were reported by 25.53% and 17.02% of patients, respectively. Uhthoff’s phenomenon and Lhermitte’s sign were present in 26.77% and 36.22% of patients, respectively. The findings underscore the importance of early ophthalmological assessments in diagnosing MS, as ON can be an initial indicator of the disease. Conclusions: The study highlights the need for precise diagnostic tools and personalized therapeutic strategies focused on specific biomarkers and pathways involved in neuroinflammation and demyelination. Early diagnosis through vigilant ophthalmologic evaluation can lead to interventions that significantly alter disease progression, improving patient outcomes and quality of life.

    Headache and Other Pain Syndromes in Multiple Sclerosis: A Narrative Review

    by Carmen Adella Sîrbu, Andreea Ruxandra Rotaru, Florina Anca Antochi, Andreea Plesa, Aida Mihaela Manole, Adina Maria Roceanu

    Multiple sclerosis is a chronic and progressive neurological disease, with an important socio-economic burden. Over time, an increased incidence of headaches like migraines and tension headaches has been observed among these patients. Headaches have not been considered as multiple sclerosis-related symptoms, even representing a red flag for multiple sclerosis diagnosis. It is uncertain whether the headache–multiple sclerosis association could be explained by the presence of common triggers or a common physiopathological mechanism (involvement of tertiary B-cell follicles). An important differential diagnosis is between multiple sclerosis attacks and migraines with aura, which can also be associated with neurological deficits. Another important aspect is the occurrence or exacerbation of the cephalalgic syndrome after the initiation of therapy for multiple sclerosis (DMTs), or the improvement of headache after the initiation of certain DMT drugs. In addition to headaches, individuals diagnosed with multiple sclerosis often report experiencing diverse pain syndromes, contributing to an additional decline in their overall quality of life. These syndromes are frequently neglected, the focus being on slowing down the progression of neurological deficits. This review aims to evaluate the characteristics of multiple-sclerosis-related headaches (frequency, possible correlation with attacks, and disease-modifying therapies) and the key distinctions in imaging characteristics between demyelinating lesions in multiple sclerosis and those observed in cases of primary headaches.
