Systolic blood pressure reduction strategies in acute ischemic stroke patients following endovascular thrombectomy: a systematic review and meta-analysis.

BACKGROUND AND AIMS: There is no clear consensus on ideal systolic blood pressure (SBP) target post-endovascular thrombectomy (EVT) in patients with acute ischemic stroke. This study intends to investigate the relationship between reducing SBP and clinical outcomes and to determine the therapeutic efficacy of moderate and intensive SBP reduction post EVT. METHODS: A comprehensive search was conducted across five electronic databases to identify studies relevant to our analysis. Data from these studies were then analyzed using pooled relative risk (RR) along with their corresponding 95 % confidence intervals (CI) for our categorical outcomes. functional independence at 90 days post-EVT was defined as a modified Rankin score (mRS) 0-2. RESULTS: Our meta-analysis included eight studies with 2922 patients: 1376 patients were treated with intensive SBP reduction, 306 with moderate SBP reduction, and 1243 with standard SBP reduction. There was no difference in the risk of functional independence at 90 days post-EVT with both intensive-SBP reduction (target 120-140 mmHg, relative risk (RR) =1.05, 95 % CI 0.82, 1.34, p = 0.72) and moderate-SBP reduction (>160 mm Hg) (RR= 0.95, 95 % CI 0.69, 1.31, p = 0.76) compared with standard SBP reduction (>180 mm Hg). The risk of symptomatic intracranial hemorrhage (sICH) did not significantly differ between standard-SBP reduction and intensive-SBP reduction (RR = 0.93, 95 % CI 0.66, 1.31, p = 0.36) or moderate-SBP reduction (0.72 (95 % CI [0.28, 1.87], p = 0.50) groups, respectively. Intensive-SBP reduction significantly decreased the risk of hemicraniectomy. CONCLUSIONS: We did not identify any difference in functional independence at 90 days in acute ischemic stroke patients with either intensive-SBP reduction or moderate-SBP reduction compared with standard SBP reduction post-EVT.

Effect of preservation versus resection of turbinate on olfactory function in endoscopic trans-nasal trans-sphenoidal pituitary surgery: a systematic review and meta-analysis.

BACKGROUND: Utilizing endoscopes in surgery offers advantages and concerns, including potential nasal function impacts. Hyposmia following Transseptal Transsphenoidal hypophysectomy ranges from 0% to 2.2%. Debates persist about managing the M.T. in endoscopic sinus surgery due to its impact on nasal function. While preservation is recommended for sinonasal health, debates continue, as certain cases require resection. Our meta-analysis aims to compare turbinate resection and preservation effects on olfactory function. METHODS: We searched five electronic databases to collect all relevant studies. Records were screened for eligibility. Data were extracted from the included studies independently. Our continuous outcomes were pooled as standardized mean difference with 95% CI. Statistical analyses was done by RevMan. RESULTS: Our meta-analysis included four studies involving 235 patients (81 males). Evaluating changes in olfaction scores, two one-month studies (82 patients) revealed no significant difference between preservation and resection groups (Std.MD = 0.05[-0.39, 0.50], p = 0.81). For three-month assessments (146 patients), SNOT tests indicated no significant difference (Std.MD = 0.21, 95% CI[-0.11, 0.54], p = 0.20). Two studies used other tests on 70 patients at three months, yielding no significant difference (Std.MD = 0.13, 95% CI [-0.35, 0.62], p = 0.59). Two six-month studies (72 patients) similarly found no significant difference (Std.MD = 0.09, 95% CI [-0.39, 0.56], p = 0.72). CONCLUSION: Our meta-analysis involving 235 patients examined olfaction score changes over various time frames in trans-nasal trans-sphenoidal pituitary surgeries. No significant differences were observed between turbinate preservation and resection groups at one month, three months, or six months post-surgery.

Ventriculoperitoneal shunt entry points in patients undergoing shunt placement: A single-center study.

Background: The ventriculoperitoneal (VP) shunt redirects cerebrospinal fluid flow, with the selection of entry points crucial for optimal outcomes. Anatomical landmarks and specific entry points, such as Kocher's, Frazier's, Keen's, and Dandy's points, have been utilized for shunt catheter placement. This study investigates the impact of various entry points on outcomes, particularly the necessity for revision procedures, in patients undergoing VP shunt placement. Methods: In this retrospective cohort study, we analyzed data from patients in our center's database, collected from October 2017 to October 2022. Participants were classified based on ventriculoperitoneal shunt entry points. The study followed STROBE guidelines. Continuous variables were presented as means with standard deviations (SD) and categorical variables as frequencies and percentages. Linear Model ANOVA and Pearson's Chi-squared tests were used for comparisons. Data analysis was conducted using Jamovi software. Results: Our study included 94 patients who underwent shunt procedures. The patients were categorized into four treatment groups: Dandy point (10), Frazier point (21), Keen point (43), and Kocher point (20). Conclusion: Our study found no significant differences in age, FOHR, and indication for shunt placement among catheter entry point subgroups. However, gender distribution, catheter length, and catheter tip location significantly varied. The proportion of patients requiring revision surgery varied among the groups, with the highest rate in the Dandy point group and the lowest in the Keen group; however, the difference among the entry groups was insignificant.

Subcutaneous preservation versus cryopreservation of autologous bone grafts for cranioplasty: A systematic review and meta-analysis.

BACKGROUND: Cranioplasty corrects cranial bone defects using various bone substitutes or autologous bone flaps created during a previous craniectomy surgery. These autologous bone flaps can be preserved through subcutaneous preservation (SP) or cryopreservation (CP). AIM: We aim to compare outcomes and complications for both SP and CP techniques to enhance the current evidence about autologous bone flap preservation. METHODS: Five electronic databases were searched to collect all relevant studies. Records were screened for eligibility. Data were extracted from the included studies independently. We categorized surgical site infection (SSI) as either due to Traumatic brain injury (TBI) or not to reveal potential variations in SSI incidence. The double-arm meta-analysis utilized risk ratios (RR) and mean differences (MD) with corresponding confidence intervals (CI) to pool categorical and continuous outcomes, respectively. Proportions with their respective 95% CIs were pooled for single-arm meta-analyses to determine outcomes related to SP technique. RESULTS: Seventeen studies involving 1169 patients were analyzed. No significant difference in SSI rates was observed between SP and CP methods in patients with or without TBI. SP was linked to shorter hospital stays in two studies (194 patients). Single-arm analysis showed a 17% revision surgery rate across five studies (375 patients) and infection rates in 17 studies for SP. New bone formation occurred in 13.2% of patients, with 19.9% showing resorption. CONCLUSION: SP and CP methods showed similar SSI rates post-craniectomy in TBI and non-TBI patients. SP was associated with reduced hospitalization time, low infection rates, and a moderate need for revision surgery.

Ticagrelor Versus Clopidogrel in Endovascular Therapy for Cerebral Aneurysms: A Systematic Review and Meta-Analysis.

BACKGROUND: Antiplatelet therapy is pivotal in endovascular treatment for intracranial aneurysms. However, there is a lack of studies comparing ticagrelor to clopidogrel in patients with aneurysms undergoing endovascular therapy. Additionally, the existing literature lacks adequate sample size, significant subgrouping, and follow-up, making our study important to cover these gaps. METHODS: We searched 5 databases to collect all relevant studies. Categorical outcomes were pooled as relative risk (R.R.) with a 95% confidence interval (CI). In the single-arm meta-analysis, outcomes were pooled as proportions and their corresponding 95% CI. RESULTS: This comprehensive analysis of 18 studies involving 2,427 patients. For thromboembolic events, the pooled (R.R.) did not show significant differences, whether considering overall events. A similar pattern was observed for thromboembolic events stratified by aneurysmal rupture status, with no significant differences in overall events. Hemorrhagic events did not also exhibit significant differences in previously mentioned stratifications. Furthermore, there were no substantial differences in death and mRS (0-2) on discharge between Ticagrelor and Clopidogrel. Single-arm meta-analyses for Ticagrelor demonstrated low rates of thromboembolic events, hemorrhage, death, and favorable mRS scores, with associated confidence intervals (CIs). Main line of endovascular treatment did not significantly affect either thromboembolic or hemorrhagic outcomes with Ticagrelor and Clopidogrel. CONCLUSIONS: We found no significant differences in key outcomes like thromboembolic events, hemorrhagic events, mortality rates, and favorable mRS (0-2) upon discharge in the studied patients between Ticagrelor and Clopidogrel. Moreover, the single-arm meta-analysis for Ticagrelor revealed low rates of thromboembolic events, hemorrhage, mortality, and high rates of favorable mRS scores.

Efficacy and safety of argatroban in the management of acute ischemic stroke: A systematic literature review and meta-analysis.

BACKGROUND: Acute ischemic stroke (AIS) is a leading cause of death and disability. AIS is caused by an embolus or thrombus that restricts blood flow to the brain tissue. Despite intravenous thrombolysis and endovascular thrombectomy, a substantial number of patients do not achieve effective reperfusion. Argatroban, a direct thrombin inhibitor, can potentially improve neurological outcomes in AIS patients. However, there are conflicting results in the medical literature regarding the efficacy and safety of argatroban in this context. OBJECTIVE: This study aims to evaluate the efficacy and safety of argatroban as monotherapy or adjunct therapy for acute ischemic stroke. METHODS: Five major databases (PubMed, Embase, Scopus, Web of Science, and Cochrane Library) were searched for randomized controlled trials (RCTs) that compared the efficacy and safety of using argatroban alone or in combination with recombinant tissue plasminogen activator (r-TPA) in the management protocol of the AIS. We used Review Manager Software (RevMan 5.4.1) for data analysis. RESULTS: We included 1393 patients from eight RCTs (of them, 726 were treated with argatroban alone or combined with r-TPA, while 667 received the placebo, standard therapy (standard treatments based on current guidelines including antihypertensive, antiplatelet agents, and statins) or endovascular r-TPA). Neither argatroban vs control nor argatroban with r-TPA vs r-TPA showed significant difference regarding the activity in daily living; (SMD= 1.69, 95% CI [-0.23, 3.61]; p = 0.09), (SMD= 0.99, 95% CI [-0.88, 2.86]; p = 0.30), respectively. Also, there was no significant difference in the National Institutes of Health Stroke Scale (NIHSS) score at seven days, the number of patients achieving modified Rankin Scale (mRS) of 0-1 or 0-2 at 90 days (p > 0.05). Argatroban did not significantly increase the risk of adverse events or symptomatic intracranial hemorrhage (ICH), or major systemic bleeding compared to control or r-TPA (p > 0.05) CONCLUSIONS: Argatroban does not demonstrate superior efficacy compared to placebo or standard therapy in terms of ADL, NIHSS and mRS outcomes. Importantly, argatroban does not significantly increase the incidence of adverse events, including symptomatic ICH and systemic bleeding.

General Anesthesia Versus Conscious Sedation for Acute Ischemic Stroke Endovascular Therapy: A Meta Analysis of Randomized Controlled Trials.

BACKGROUND: Endovascular thrombectomy (E.V.T.) is the primary treatment for acute ischemic stroke (AIS). Nevertheless, the optimal choice of anesthetic modality during E.V.T. remains uncertain. This systematic review and meta-analysis aim to summarize existing literature from randomized controlled trials (RCTs) to guide the selection of the most appropriate anesthetic modality for AIS patients undergoing E.V.T. METHODS: By a thorough search strategy, RCTs comparing general anesthesia (G.A.) and conscious sedation (C.S.) in E.V.T. for AIS patients were identified. Eligible studies were independently screened, and relevant data were extracted. The analysis employed pooled risk ratio for dichotomous outcomes and the mean difference for continuous ones. RCTs quality was assessed using the Cochrane Risk of Bias assessment tool 1. RESULTS: In the functional independence outcome (mRS scores 0-2), the pooled analysis did not favor either G.A. or C.S. arms, with an RR of 1.10 [0.95, 1.27] (P = 0.19). Excellent (mRS 0-1) and poor (≥3) recovery outcomes did not significantly differ between G.A. and C.S. groups, with RR values of 1.03 [0.80, 1.33] (P = 0.82) and 0.93 [0.84, 1.03] (P = 0.16), respectively. Successful recanalization significantly favored G.A. over C.S. (RR 1.13 [1.07, 1.20], P > 0.001). CONCLUSIONS: G.A. had superior recanalization rates in AIS patients undergoing endovascular therapy, but functional outcomes, mortality, and NIHSS scores were similar. Secondary outcomes showed no significant differences, except for a higher risk of hypotension with G.A. More trials are required to determine the optimal anesthesia approach for thrombectomy in AIS patients.

Intravenous cangrelor use for neuroendovascular procedures: a two-center experience and updated systematic review.

Background: The optimal antiplatelet therapy regimen for certain neuroendovascular procedures remains unclear. This study investigates the safety and feasibility of intravenous dose-adjusted cangrelor in patients undergoing acute neuroendovascular interventions. Methods: We conducted a retrospective chart review of all consecutive patients on intravenous cangrelor for neuroendovascular procedures between September 1, 2020, and March 13, 2022. We also conducted an updated systematic review and meta-analysis using PubMed, Scopus, Web of Science, Embase and the Cochrane Library up to February 22, 2023. Results: In our cohort, a total of 76 patients were included [mean age (years): 57.2 ± 18.2, males: 39 (51.3), Black: 49 (64.5)]. Cangrelor was most used for embolization and intracranial stent placement (n = 24, 32%). Approximately 44% of our patients had a favorable outcome with a modified Rankin Scale (mRS) score of 0 to 2 at 90 days (n = 25/57); within 1 year, 8% of patients had recurrent or new strokes (n = 5/59), 6% had symptomatic intracranial hemorrhage [sICH] (4/64), 3% had major extracranial bleeding events (2/64), and 3% had a gastrointestinal bleed (2/64). In our meta-analysis, 11 studies with 298 patients were included. The pooled proportion of sICH and intraprocedural thromboembolic complication events were 0.07 [95% CI 0.04 to 1.13] and 0.08 [95% CI 0.05 to 0.15], respectively. Conclusion: Our study found that intravenous cangrelor appears to be safe and effective in neuroendovascular procedures, with low rates of bleeding and ischemic events. However, further research is needed to compare different dosing and titration protocols of cangrelor and other intravenous agents.

Safety and efficacy of tirofiban in the management of stroke: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: About 30 % of stroke patients have experienced unsuccessful reperfusion following endovascular therapy. Mechanical thrombectomy instruments may contribute to this by stimulating platelet aggregation. Tirofiban is a selective and rapidly activated antagonist of the platelets nonpeptide glycoprotein IIb/IIIa receptors that can reversibly suppress platelet aggregation. But, data from the medical literature are conflicting regarding its safety and efficacy for stroke patients. Hence, this study was designed to assess the safety and efficacy of tirofiban in stroke patients. METHODS: Five major databases (PubMed, Scopus, Web of Science, Embase, and Cochrane library) were searched till December 2022. The Cochrane tool was used for risk of bias assessment, and the RevMan 5.4 was utilized for data analysis. RESULTS: Seven RCTs with 2088 stroke patients were included. Tirofiban significantly increased the number of patients with mRS 0 score after 90 days than control; RR= 1.39, 95 %CI [1.15, 1.69]; p = 0.0006. Additionally, it reduced the NIHSS score after seven days; MD= -0.60, 95 %CI [-1.14, -0.06]; p = 0.03. However, tirofiban increased the incidence of intracranial haemorrhage (ICH); RR= 1.22, 95 %CI [1.03, 1.44]; p = 0.02. Other assessed outcomes showed insignificant results. CONCLUSIONS: Tirofiban was associated with a higher mRS 0 score after three months and a lower NIHSS score after seven days. However, it is associated with higher ICH. Multicentric trials are required to provide more convincing proof of its utility.

The clinical aspects of septo-optic dysplasia: A narrative review with illustrative case report.

INTRODUCTION AND IMPORTANCE: Septo-optic dysplasia (SOD) is a rare congenital disorder characterized by abnormal development of the optic nerve, pituitary gland, hypothalamus, and midline brain structures, with heterogeneous presentation among cases. CASE PRESENTATION: We report a seven-month-old male infant presented with persistent vomiting and delayed developmental milestones. He had dysmorphic facial features, bilateral esotropia, a head circumference of 50 cm, and scoliosis. His muscle tone was high (clasp-knife spasticity) and his deep tendon reflexes were brisk in the four limbs. Clinical evaluation and brain MRI confirmed the diagnosis of SOD, for which, he was subjected for multidisciplinary evaluation. Genetic testing revealed an autosomal dominant TUBB gene mutation. On follow-up, at the age of three years, he presented with recurrent focal motor and generalized seizures, which were controlled with levetiracetam. CLINICAL DISCUSSION: The ophthalmic manifestations of SOD include optic nerve hypoplasia, which can lead to visual impairments such as nystagmus, strabismus, and reduced visual acuity. Midline brain anomalies involve structures like the corpus callosum and septum pellucidum, and can result in cognitive and neurological deficits. Hypothalamic-pituitary axis abnormalities can cause endocrine dysfunction and growth abnormalities. The clinical heterogeneity of SOD is attributed to variable phenotypic penetration and genetic mutations. Environmental risk factors may also contribute to the development of the syndrome. CONCLUSION: SOD is a complex disorder with diverse clinical manifestations. Early diagnosis and multidisciplinary management are crucial for optimizing patient outcomes. Further research is needed to understand the underlying genetic and environmental factors involved in SOD and to develop targeted treatments.

Spinal Langerhans cell histiocytosis with cord compression and neurological deficits: A case report.

INTRODUCTION AND IMPORTANCE: Langerhans cell histiocytosis (LCH) is a rare idiopathic disease that uncommonly affect the spine in adults. CASE PRESENTATION: In this report, we presented a rare adult case of symptomatic spinal LCH with asymptomatic systemic involvement. She was a 46-year-old previously healthy lady who presented with subacute thoracic sensory level, urine retention, constipation, and pyramidal paraplegia. Her magnetic resonance imaging (MRI) of the spine revealed T6 compression fracture with an epidural mass compressing the cord. CLINICAL DISCUSSION: Sellar MRI showed pituitary gland enlargement with hyperintense signal in the posterior lobe. Positron emission tomography (PET)/computed tomography (CT) scan showed an increased uptake in the right parotid gland uptake and renal cortex, indicating systemic involvement. CONCLUSION: Surgical excision, decompression, and screw fixation were performed, and the patient improved. The prognosis is usually good in patients with solitary spinal LCH.

A rare case of pituicytoma-related hyperprolactinemia due to mass effect on infundibular stalk-Case report.

INTRODUCTION AND IMPORTANCE: Pituicytomas are extremely rare cancers of the sellar and suprasellar region that appear from the infundibulum or posterior pituitary. World Health Organization in 2007, described pituicytoma as a low-grade tumour (Grade I) in the taxonomy of CNS cancers. The tumour can frequently simulate a pituitary adenoma and is also linked with hormonal disorders. Distinguishing a pituitary adenoma from a pituicytoma can be challenging. We present a rare case report where an elderly female showed high levels of prolactin mainly due to mass effects along with diagnostic, imaging, and immunohistochemical characteristics of pituicytoma. CASE PRESENTATION: A 50-year-old female known case of hypothyroidism, complained of headache associated with dizziness and blurry vision. Her prolactin levels were high which led to the suspicion of pituitary involvement and underwent MRI. The imaging study revealed a well-defined, completely suprasellar, homogenously enhancing mass lesion arising from the left lateral aspect of the pituitary infundibulum. The initial differential diagnosis from the imaging included an ectopic pituitary gland, adenoma, pituicytoma, or hypothalamic glioma. She underwent a right supra-orbital craniotomy for debulking of the pituitary stalk lesion. The histopathological diagnosis was pituicytoma, WHO grade I. CLINICAL DISCUSSION: The clinical manifestations are mostly depended upon the tumour mass and position. They typically present due to mass effects leading to hormonal disorders. The imaging studies are the backbone of the clinical diagnosis along with the histopathological findings. Surgical resection is the preferred treatment for pituicytoma, with an exceptionally low recurrence rate (4.3 %) following complete removal. CONCLUSION: Pituicytomas are slow-growing, benign glial growths. It is challenging to diagnose before surgery as its clinical manifestations and imaging findings look like those of non-functional pituitary adenomas. The effective treatment for pituicytoma is gross total resection by the endoscopic method or transcranial technique.

Diffusion tensor imaging with tractography in surgical resection of brainstem cavernous malformations: a systematic review and meta-analysis.

Brainstem cavernous malformations are benign subset of cerebral cavernous malformations, which need a special intervention owing to being vital and complex. The diffusion tensor imaging technique, a well-recognized neuroimaging tool, can visualize the white matter tracts and their surroundings and provide promising surgical outcomes. This systematic review and meta-analysis evaluated the effect of preoperative diffusion tensor imaging in patients undergoing surgical resection of brainstem cavernous malformations. Five databases, including PubMed, Scopus, Web of Science, Cochrane Library, and Google Scholar, were searched using a comprehensive search strategy to find any article matching our inclusion criteria. We used Comprehensive Meta-Analysis (CMA) software to analyze the collected data, get the evidence, and report the results as event rate (ER), with their 95% confidence interval (CI). Twenty-eight studies involving 467 patients matched our criteria and 19 studies entered the analysis. Our analysis showed that, in patients undergoing surgical resection of brainstem cavernous malformations assisted by preoperative diffusion tensor imaging, 82.21% achieved total resection. About 12.4% of patients achieved partial resection, 65.65% improved, 8.07% worsened, 25.04% showed no change, 3.59% experienced postoperative re-bleeding, and 0.87% died. The utilization of preoperative diffusion tensor imaging significantly increased the proportion of improved patients and decreased the proportion of worsened patients. However, further controlled research is needed to draw a definite conclusion about the usefulness of its role.

Comparison of Burr-Hole Craniostomy versus Twist-Drill Craniostomy Operations for Patients with Chronic Subdural Hematoma: A Systematic Review and Network Meta-Analysis.

BACKGROUND: Chronic subdural hematoma (CSDH) represents one of the most common neurologic disorders in the elderly. However, the optimum surgical option remains questionable. This study aims to compare the safety and efficacy of single burr-hole craniostomy (sBHC), double burr-hole craniostomy (dBHC), and twist-drill craniostomy (TDC) in patients with CSDH. METHODS: We searched PubMed, Embase, Scopus, Cochrane, and Web of Science until October 2022 for prospective trials. Primary outcomes comprised recurrence and mortality. The analysis was performed using R software, and the results were reported as risk ratio (RR) and 95% confidence interval (CI). RESULTS: Data from 11 prospective clinical trials were included in this network meta-analysis. We found that dBHC significantly decreased recurrence and reoperation rates compared with TDC (RR = 0.55, CI, 0.33-0.90 and RR = 0.48, CI, 0.24-0.94, respectively). However, sBHC showed no difference compared with dBHC and TDC. There was no significant difference among dBHC, sBHC, and TDC regarding the hospitalization duration, complication rates, mortality, and cured rates. CONCLUSIONS: dBHC seems to be the best modality for CSDH compared with sBHC and TDC. It showed significantly less recurrence and reoperation rates compared with TDC. On the other hand, dBHC showed no significant difference with the other comparators regarding complication, mortality, and cure rates in addition to the hospitalization duration.

Spinal paraganglioma at the conus medullaris mimicking schwannoma: A case report.

BACKGROUND: Paragangliomas of the spine are extremely rare, and they should be considered in the differential diagnosis of spinal tumors due to its overlapping clinical and radiological features with many spinal tumors. CASE REPORT: In this article, we present a 30-year-old lady who presented with low back pain and radicular neuropathic pain at L1 dermatome which was intractable to medical surgery. Her magnetic resonance imaging (MRI) of the lumbosacral spine revealed a T1 isointense, T2 heterogeneously hyperintense intradural extramedullary lesion at the conus medullaris with strong homogenous enhancement on contrast administration. The lesion was surgically excised completely with L1 laminectomy, and the histopathological picture was suggestive of paraganglioma. The patient's complaints resolved fully postoperatively, and there was no evidence of recurrence on long-term follow-up. CONCLUSION: Due to the absence of pathognomonic clinical or radiological features of paragangliomas, they should be taken into consideration in the differential diagnosis of spinal tumors. They share similar clinical and radiological features of schwannomas, ependymomas, and hemangioblastomas. The diagnosis is usually made postoperatively based on histopathological examination.

Lateral cervical approach for ventrally located upper cervical meningioma: experience of 14 cases with a narrative comparison with other surgical techniques.

BACKGROUND: Upper cervical meningioma represents a large portion of intradural extramedullary tumors that occur in the cervical spinal canal. Most of them are located ventrally or ventrolateral to the spinal cord. Reaching lesions at this location surgically is technically challenging. OBJECTIVES: The ideal approach to ventrally located upper cervical lesions continues to be controversial. The aim of this study was to discuss the advantage of the lateral cervical approach and compare it with other surgical routes. METHODS: This retrospective study was conducted on all cases of ventrally located upper cervical meningiomas (C1-C3) who have been operated on using the lateral cervical approach in a tertiary neurosurgery unit between 2006 and 2020. Demographic, clinical, surgical, and follow-up data were collected from hospital records. RESULTS: During the study period, fourteen patients (Nine females and five males, aged 42-73 years) were recruited. The follow-up period was 2-16 years. The most frequent presenting symptoms were neck pain, occipital headache, motor deficits, and sensory disturbances. Total excision was achieved in all patients. All patients who had preoperative motor deficits improved significantly postoperatively, and those who presented with sensory disturbance had partial recovery. There was neither mortality nor permanent neurological morbidity. CONCLUSION: A lateral cervical approach is a safe approach for ventrally located upper cervical lesions. In our series, it offered enough exposure for a safe dissection and total or extensive subtotal removal of the tumors. Retraction or rotation of the neuroaxis was avoided, and the incidence of complications (injury of neural or vascular structures, instability, infection) was very low.

The "Talk and Die" phenomenon in traumatic brain injury: A meta-analysis.

INTRODUCTION: Risk factors for "Talk and Die" phenomenon following Traumatic Brain Injury (TBI) are poorly identified in literature, and studies attempting to identify those factors yielded conflicting results. AIM: To provide level 1 evidence on the significance of potential risk factors predictive of "Talk and Die" phenomenon following TBI. METHODOLOGY: A systematic review and meta-analysis were performed. A fixed effect model for age, admission Glasgow Coma Scale (GCS), Abbreviated Injury Scale (AIS), and Injury Severity Score (ISS) parameters were performed. RESULTS: Of 35,582 patients analyzed, 2397 patients experienced the "Talk and Die" phenomenon. Absence of intracranial hematoma (OR=0.137, CI: 0.276-0.991, =0.047), Older age (Hedge's g=0.153, CI: 0.104-0.202, p < 0.001), lower GCS score (Hedge's g=-0.111, CI: 0.062-0.160, p < 0.001), lucid interval duration of ≥ 24 h (OR=4.176, CI: 2.806-6.215, p = 0.000), higher AIS scores (Hedge's g was 0.138, CI: 0.089-0.188, p < 0.001), and lower ISS scores (Hedge's g=0.137, CI: 0.088-0.186, p < 0.001) were identified as risk factors for mortality. CONCLUSION: Considering our results and others, we conclude that absence or presence of intracranial hematomas, older age, lower GCS, lucid interval ≥ 24 h, High AIS, and low or high ISS predispose to a "Talk and Die" phenomenon following a Traumatic Brain Injury.
