Prognostic variables predict clinical outcome after decompressive craniectomy: A single institute experience; A retrospective study.

Decompressive craniectomy (DC) is a well-established neurosurgical intervention in patients with high intracranial pressure who fail to respond to medical treatment. Data on predictive factors for functional outcomes in patients with DC who have malignant middle cerebral artery (MCA) infarction as opposed to intracranial hemorrhage (ICH) are scarce. Eighty-four patients who underwent DC treatment for ICH and malignant MCA infarction were examined. All patients underwent surgery in the Bahrain Salmaniya Medical Complex Neurosurgery Unit between January 2017 and June 2021. To determine whether any of these demonstrated a link to the functional outcome, radiographic factors were compared with clinical data. The postsurgical midline shift (MLS) (ICH group) showed the strongest correlation (ρ = 0.434; P = .006), as in the MCA infarction group as well (ρ = 0.46; P = .005). Further analyses using binary logistic regression with postsurgical basal cistern status and ∆ MLS, and it was observed to be statistically significant (odds ratios: 0.067, 95% CI: 0.007, 0.67; P = .021). The initial Glasgow coma scale, postsurgical MLS, basal cistern status, and ∆ are Measurable variables that can be used to predict outcomes in the groups with ICH and MCA infarction.

C2 versus C3 or C4 as the upper instrumented vertebra for long-segment cervical fusions: a systematic review and meta-analysis.

OBJECTIVE: Selecting C2 versus C3 or C4 (i.e., C3/C4) as the rostral anchoring level in long-segment cervical fusions is a common clinical conundrum. The data regarding proximal failure in long constructs of the cervical spine is scarce. The objective of this study was to systematically review the published literature and perform a meta-analysis of the incidence for proximal adjacent-segment disease (ASD) in the context of long cervical fusions and cervicothoracic fusions ending in C2 versus those ending in the subaxial spine (C3 or C4). METHODS: Using the PRISMA guidelines, the authors performed a search of the PubMed/MEDLINE, Embase/Ovid, and Cochrane Central databases to identify all full-text articles in the English-language literature with the following inclusion criteria: 1) studies including patients with the upper instrumented vertebra (UIV) at C2 versus C3/C4; 2) patients undergoing ≥ 3-level posterior cervical fusion; and 3) indication for surgery of degenerative disc disease, cervical spondylotic myelopathy, or cervical deformity. Studies that were not published in the English language, case reports, review articles, letters to the editor, and meeting abstracts were excluded. A meta-analysis was conducted using a fixed-effects model when I2 values were below 70%. Conversely, when I2 values were equal to or greater than 70%, a random-effects model was used. A funnel plot was used to assess the presence of publication bias. RESULTS: Seven studies consisting of 1215 patients were included in the meta-analysis. There were 403 (32.8%) patients in the C2 UIV group and 812 (67.2%) patients in the C3/C4 UIV group. When the 7 studies were analyzed, the overall rate of reoperation was comparable between the C2 (9.2%) and C3/C4 (9.4%) UIV groups (p = 0.93) but the rate of surgical ASD due to proximal pathology was 1.2% and 3%, respectively (OR 0.36, 95% CI 0.15-0.86; p = 0.02). When comparing between groups, no statistical difference was found regarding the rate of reoperation due to distal pathology or surgical infection. CONCLUSIONS: Long-segment cervical or cervicothoracic constructs that anchor into C2 may have similar complication rates but lower revision rates for proximal ASD than constructs that anchor into the subaxial spine.

Clinical Outcomes and Complication Profile of Spine Surgery in Septuagenarians and Octogenarians: Case Series.

OBJECTIVE: The aging global population presents an increasing challenge for spine surgeons. Advancements in spine surgery, including minimally invasive techniques, have broadened treatment options, potentially benefiting older patients. This study aims to explore the clinical outcomes of spine surgery in septuagenarians and octogenarians. METHODS: This retrospective analysis, conducted at a US tertiary center, included patients aged 70 and older who underwent elective spine surgery for degenerative conditions. Data included the Charlson Comorbidity Index (CCI), ASA classification, surgical procedures, intraoperative and postoperative complications, and reoperation rates. The objective of this study was to describe the outcomes of our cohort of older patients and discern whether differences existed between septuagenarians and octogenarians. RESULTS: Among the 120 patients meeting the inclusion criteria, there were no significant differences in preoperative factors between the age groups (P > 0.05). Notably, the septuagenarian group had a higher average number of fused levels (2.36 vs. 0.38, P = 0.001), while the octogenarian group underwent a higher proportion of minimally invasive procedures (P = 0.012), resulting in lower overall bleeding in the oldest group(P < 0.001). Mobility outcomes were more favorable in septuagenarians, whereas octogenarians tended to maintain or experience a decline in mobility(P = 0.012). A total of 6 (5%) intraoperative complications and 12 (10%) postoperative complications were documented, with no statistically significant differences observed between the groups. CONCLUSIONS: This case series demonstrates that septuagenarians and octogenarians can achieve favorable clinical outcomes with elective spine surgery. Spine surgeons should be well-versed in the clinical and surgical care of older adults, providing optimal management that considers their increased comorbidity burden and heightened fragility.

Is young adult idiopathic scoliosis a distinct clinical entity from adolescent idiopathic scoliosis? a Systematic Review and Meta-analysis comparing pre-operative characteristics and operative outcomes.

PURPOSE: This study aims to conduct a systematic review of the literature comparing pre-operative, intraoperative, and post-operative characteristics between adolescent idiopathic scoliosis (AIS) and young adult idiopathic scoliosis (YAdIS) patients. METHODS: Following PRISMA guidelines, we conducted a search of the PubMed/Medline, EMBASE, and Cochrane Central databases to identify full-text articles in the English-language literature. Our inclusion criteria were studies that compared preoperative, intraoperative, and postoperative characteristics between AIS and YAdIS patients. We performed a meta-analysis reporting mean difference (MD) for continuous variables and Odds ratios (ORs) to assess differences in postoperative complications. RESULTS: Seven studies consisting of 1562 patients were included in the meta-analysis. The AIS group exhibited less intraoperative bleeding and shorter surgical procedures, with a mean difference between groups of 122.3 ml (95% CI 46.2-198.4, p = 0.002) and 28.7 min (95% CI 6.5-50.8, p = 0.01), respectively. Although the preoperative Cobb angle did not differ between groups (p = 0.65), patients with AIS achieved superior postoperative deformity correction, with a mean difference of 7.3% between groups, MD - 7.3 (95% CI - 9.7, - 4.8, p < 0.00001), and lower postoperative Cobb angles of the major curve, MD 4.2 (95% CI 3.1, 5.3, p < 0.00001). YAdIS patients were fused, on average, 0.2 more vertebral levels than AIS patients, MD 0.2 (95% CI 0.01, 0.5, p = 0.04). AIS patients experienced a significantly shorter length of stay after the surgical procedure, with an MD of 0.8 days (95% CI 0.1, 1.6, p = 0.02). No significant difference was found between groups in terms of complications (p = 0.19). CONCLUSIONS: YAdIS should be regarded as a distinct surgical entity, characterized by increased bleeding, longer surgical duration, greater deformity correction challenges, and the need for fusion of additional vertebral levels compared to AIS. Surgeons should be mindful of these differences and discuss them with patients and their families, especially in cases where the correction of the AIS deformity is delayed and there is a high risk of progression after skeletal maturity. Further research is needed to explore alternative surgical techniques and enhance outcomes for YAdIS patients.

Anxiety and Depression in Pediatric-Onset Traumatic Spinal Cord Injury: A Systematic Review.

BACKGROUND: Traumatic spinal cord injury (TSCI) is a debilitating neurological condition with significant long-term consequences on the mental health and well-being of affected individuals. We aimed to investigate anxiety and depression in individuals with pediatric-onset TSCI. METHODS: PubMed, Scopus, and Web of Science databases were searched from inception to December 20th, 2022 following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, and studies were included according to the eligibility criteria. RESULTS: A total of 1013 articles were screened, and 18 studies with 4234 individuals were included in the final review. Of these, 1613 individuals (38.1%) had paraplegia, whereas 1658 (39.2%) had tetraplegia. A total of 1831 participants (43.2%) had complete TSCI, whereas 1024 (24.2%) had incomplete TSCI. The most common etiology of TSCI with 1545 people (36.5%) was motor vehicle accidents. The youngest mean age at the time of injury was 5.92 ± 4.92 years, whereas the oldest was 14.6 ± 2.8 years. Patient Health Questionnaire-9 was the most common psychological assessment used in 9 studies (50.0%). Various risk factors, including pain in 4 studies (22.2%), reduced sleep quality, reduced functional independence, illicit drug use, incomplete injury, hospitalization, reduced quality of life, and duration of injury in 2 (11.1%) studies, each, were associated with elevated anxiety and depression. CONCLUSIONS: Different biopsychosocial risk factors contribute to elevated rates of anxiety and depression among individuals with pediatric-onset TSCI. Individuals at risk of developing anxiety and depression should be identified, and targeted support should be provided. Future large-scale studies with long-term follow-up are required to validate and extend these findings.

Blister-like Cerebral Aneurysm after Endovascular Catheterization: A Case Report and Literature Review.

Endovascular procedures have become a mainstay in the treatment of neurovascular pathologies like arteriovenous malformations and aneurysms. Catheter-induced blister-like aneurysms (BBAs) have not been described so far in the neurosurgical literature. The authors report a rare case of a possible, catheter-induced (iatrogenic) BBA of the supra-ventral wall of the internal carotid artery (ICA) post-endovascular coiling for posterior communicating artery (PComA) aneurysm and bring the rapid progression of BBA and the grade prognosis. A 46-year-old female presented with convulsions. Imaging studies showed diffuse subarachnoid haemorrhage (SAH) and a right saccular PComA aneurysm. Endovascular coiling of the aneurysm was performed, and it was uneventful. The patient had a good outcome (modified Rankin Scale of 1) with no neurological deficits and was discharged home on day five. However, on day nine after the first ictus, she experienced a severe headache at home and was rushed to the emergency room where she collapsed. A cranial computed tomography scan showed intracerebral haemorrhage with intraventricular extension and SAH. A cerebral angiogram showed a BBA of the supra-ventral wall of the ICA. A BBA needs to be considered as a complication of an endovascular procedure that may result in rapid neurological deterioration post-coiling due to rupture. The report also illustrates the rapid and catastrophic presentation of BBA.

Supraorbital vs pterional keyhole for anterior circulation aneurysms: A systematic review and meta-analysis.

Background: The supraorbital approach is a modification of the traditional pterional approach, and it offers the benefits of a shorter skin incision and a smaller craniotomy than the pterional approach. The purpose of this systemic review study was to compare the two surgical approaches for raptured and unruptured anterior cerebral circulation aneurysms. Methods: We searched PubMed, EMBASE, Cochrane Library, SCOPUS, and MEDLINE, up to August 2021, for published studies on the supraorbital vs pterional keyhole approach for anterior cerebral circulation aneurysms, and reviewers performed a brief qualitative descriptive analysis of both approaches. Results: Fourteen eligible studies were included in this systemic review. Results indicated that the supraorbital approach for anterior cerebral circulation aneurysms had fewer ischemic events compared to pterional approach. However, no significant difference between both groups in terms of complications such as intraoperative aneurysm rupture, brain hematoma, and postoperative infections for ruptured aneurysms. Conclusion: The meta-analysis suggests that the supraorbital method for clipping anterior cerebral circulation aneurysms might be a viable alternative to the traditional pterional method as the supraorbital group had decreased ischemic events compared to the pterional group, however, the associated difficulties in utilizing this approach among ruptured aneurysms with cerebral oedema and midline shifts further needs to be understood.

Indications for Fusion With Intradural Spine Tumor Resection in Adults: A Systematic Review and Meta-analysis.

BACKGROUND: The evidence for instrumented fusion in the setting of degenerative, traumatic, or congenital deformity is well established. Data on fusion indications in intradural spinal tumors (IDST) are scarce and reduced to retrospective studies. The objective of this work is to systematically review the published literature since 2015 and analyze the change of practice patterns for stabilization and fusion after intradural tumor resection in adults. METHODS: A systematic literature review was performed via PubMed with the terms: "intradural spinal tumors", "intramedullary spinal tumors", and "intraspinal tumors". The analysis was limited to adult patients with IDST and studies with more than 10 patients. Data on the proportion of patients who underwent instrumentation and had postoperative deformity was pooled in a meta-analysis. RESULTS: A total of 1073 articles were identified and 47 papers were selected. All the studies were retrospective series and a total of 2473 patients were included. The follow-up ranged from 1 to 96 months, the pooled spinal fixation rate was 6% (95% CI 4.5%-7.6%), the pooled laminoplasty rate was 14.4% (95% CI 5.9%-23%), the pooled rate of postoperative deformity or malalignment in patients with a follow up of at least 6 months was 2.1% (95% CI 1.2%-3%) and just 7 patients were reoperated due to progressive deformity. CONCLUSIONS: Based on existing evidence, the rate of fusion during resection of intradural spinal tumors is low. Prophylactic fixation is often unnecessary and only indicated in unique cases that require extensive bony resection.

Biportal endoscopic surgery for lumbar spine herniated discs: a narrative review of its clinical application and outcomes.

Lumbar disk herniation (LDH) is a common condition affecting millions worldwide. The management of LDH has evolved over the years, with the development of newer surgical techniques that aim to provide better outcomes with minimal invasiveness. One promising emerging technique is biportal endoscopic spinal surgery (BESS), which utilizes specialized endoscopic equipment to treat LDH through two small incisions. This review aims to assess the effectiveness of BESS as a management option for LDH by analyzing the available literature on surgical outcomes and potential complications associated with the technique. Our review shows that BESS is associated with favorable postoperative results as judged by clinical scoring systems, such as visual analog scale, Oswestry disability index, and MacNab criteria. BESS has several advantages over traditional open surgery, including minimized blood loss, a shorter duration of hospitalization, and an expedited healing process. However, the technique has limitations, such as a steep learning curve and practical challenges for surgeons. Our review offers recommendations for the optimal use of BESS in clinical practice, and provides a foundation for future research and development in this field, aiming to improve patient outcomes and quality of life.

Intractable Trigeminal Neuralgia Secondary to Osteoma of the Clivus: A Case Report and Literature Review.

Skull base osteomas (SBOs) are benign tumors that are frequently detected on radiographic images by coincidence. They are known for being slow-growing tumors and rarely symptomatic. The therapeutic approach for SBOs can differ substantially. Depending on the symptoms, size, and location of the tumor, this can range from serial observation to vigorous surgical extirpation. Clival osteoma is extremely rare. We report a case of clival osteoma, causing intractable trigeminal neuralgia due to the pressure effect on the trigeminal nerve at Meckel's cave. We also provide a review of pertinent literature. A 37-year-old woman presented with intractable trigeminal neuralgia. Cranial magnetic resonance imaging (MRI) demonstrated a large, lobulated, extra-axial lesion involving the right cerebellopontine angle and epicentering the clivus. Pathologically, the specimen was proven to be osteoma. The patient reported complete symptom resolution over a 4-year follow-up period. To the best of the authors' knowledge, this is the first clinical case of intractable trigeminal neuralgia due to clival osteoma.

Immunoglobulin G4-Related Disease Masquerading an Epidural Spinal Cord Tumor.

Background Immunoglobulin G4-related disease (IgG4-RD) is a recently identified multisystemic fibroinflammatory condition of unclear etiology. IgG4-RD of the epidural tissue causing spinal cord compression is extremely rare. Case description Here, we present a 27-year-old male with epidural mass, causing spinal cord compression at the level of D5-D6. The mass proved pathologically to be epidural inflammatory pseudotumor (IPT) related to IgG4. Spinal decompression was done. The patient was started on steroid treatment and reported a complete resolution of his symptoms over a 3 years' follow-up period. Conclusion To the authors' knowledge, this is the first case of IgG4-related epidural IPT and spinal cord compression in Bahrain and the Middle East. IgG4-RD should always be considered as a part of the differential diagnosis of spinal tumors.

Assessing primary health care nurses' knowledge toward immunizations: A quantitative study.

Background: The current nursing workforce needs to be skilled, confident, and competent to address the rapid change in Primary Health Care services, to align with the National Vision of Qatar. This is emphasized in the Primary Health Care Strategy 2018-2023. This strategy outlines the need of having a skilled nursing workforce to administer and educate the public about the importance of immunizations. Primary Health Care nurses emanate from several nationalities and hence possess various level of knowledge and background related to immunization administration. Design and methods: To assess Primary Health Care nurses' knowledge before and after the delivered immunization education program in Qatar. The study was part of a Sequential mixed method research study that aimed to assess the Primary Health Care nurses' knowledge, attitude, and practice of nurses before and after the conducted training program. A self-administered survey, specifically developed for the research project was loaded in Qualtrics and sent to participants of the immunization education program before and after training. Participants were trained in two cohorts from October to December, 2018 in Qatar. For the purposes of this paper, data about the immunization knowledge was statistically analyzed using the SPSS Software version 25 and Microsoft Excel. Results: Specific areas were identified as knowledge gaps among the participants of the two cohorts. Moreover, the developed education program showed overall improvement in the participants' knowledge. Conclusions: The study results have demonstrated that the delivered immunization education program significantly increases the participants' knowledge about immunization in certain areas of the primary healthcare clinics they work, including vaccine safety, efficiency, and contraindications in the delivery of vaccines to the public.
