RESUMEN
OBJECTIVE: Surgery plays a key role in the management of brain metastases. Stratifying surgical risk and individualizing treatment will help optimize outcomes because there is clinical equipoise between radiation and resection as treatment options for many patients. Here, the authors used a multicenter database to assess the prognostic utility of baseline frailty, calculated with the Risk Analysis Index (RAI), for prediction of mortality within 30 days after surgery for brain metastasis. METHODS: The authors pooled patients who had been surgically treated for brain metastasis from the American College of Surgeons National Surgical Quality Improvement Program database (2012-2020). The authors studied the relationship between preoperative calculated RAI score and 30-day mortality after surgery for brain metastasis by using linear-by-linear proportional trend tests and binary logistic regression. The authors calculated C-statistics (with 95% CIs) in receiver operating characteristic (ROC) curve analysis to assess discriminative accuracy. RESULTS: The authors identified 11,038 patients who underwent brain metastasis resection with a median (interquartile range) age of 62 (54-69) years. The authors categorized patients into four groups on the basis of RAI: robust (RAI 0-20), 8.1% of patients; normal (RAI 21-30), 9.2%; frail (RAI 31-40), 75%; and severely frail (RAI ≥ 41), 8.1%. The authors found a positive correlation between 30-day mortality and frailty. RAI demonstrated superior predictive discrimination for 30-day mortality as compared with the 5-factor modified frailty index (mFI-5) on ROC analysis (C-statistic 0.65, 95% CI 0.65-0.66). CONCLUSIONS: The RAI frailty score accurately estimates 30-day mortality after brain metastasis resection and can be calculated online with an open-access software tool: https://nsgyfrailtyoutcomeslab.shinyapps.io/BrainMetsResection/. Accordingly, RAI can be utilized to measure surgical risk, guide treatment options, and optimize outcomes for patients with brain metastases. RAI has superior discrimination for predicting 30-day mortality compared with mFI-5.

The management of base of skull (BS) chordomas is a neurosurgical conundrum owing to their close proximity to the critical neurovascular structures. Surgical resection is the gold standard treatment followed by adjuvant radiotherapy which includes photon therapy, proton beam therapy (PBT), gamma knife radiosurgery, etc. PBT has become an unparalleled therapeutic modality in the management of BS chordomas. The aim of this systematic review was to assess the outcomes in BS chordoma patients who received PBT as a primary or adjuvant therapy. PubMed and Cochrane databases were screened till May 2022. Following the PRISMA guidelines, studies were reviewed thoroughly, and the data of the included study was extracted. Statistical analysis was performed using the SAS 9.4 with P value < .05 considered as significant. Sixteen studies with 752 patients were included. The majority of the patients were adults (> 18 years) with a male:female ratio of 1.2. The most common clinical features were cranial nerve (3rd, 6th, or 12th) palsy and hearing impairment. Ninety-five percent of the patients underwent surgical resection before PBT. The mean PBT dose received was 74.02 cGe (cobalt gray equivalent). Eighty percent of the patients showed a positive response to the therapy defined in terms of tumor regression. Five-year local control (LC), overall survival (OS), and progression-free survival (PFS) were calculated as 76.6%, 79.6%, and 89%, respectively. Statistical analysis revealed none of the factors had any significant association with 5-year LC. PBT is a growing therapeutic technique that has revolutionized the treatment of BS chordomas.

OBJECTIVE: Electronic Health Record (EHR) system is now considered the backbone of effective storage and retrieval of patient records in a healthcare setup. This study is an attempt to assess the knowledge, attitude and practice of healthcare professionals in the use of Electronic Health Record system in patient care. METHODS: It was a comparative cross-sectional study, conducted among the clinicians working in King Khaled Hospital, Almajmaah, Saudi Arabia. The data was collected from 260 clinicians using systematic random sampling technique. A pre-validated questionnaire was used to gather the data. Nineteen items were graded based on the adaptability, usability and knowledge of the participants. The total duration of the study from conception to completion was 6 months. RESULTS: There were 146 (56.2%) Saudis and 114 (43.8%) non - Saudi participants. Knowledge of computer was slightly more among Saudis 134 (51.5%) than non - Saudis 104 (40.0%) (p>0.05). Saudis had an overall positive attitude toward using the EHR as compared to non-Saudis (p<0.001).Frequency of accessing computers daily was more among Non-Saudi practitioners 93 (35.8%) as compared to the Saudis 85 (32.7%) which was statistically significant (p<0.001). CONCLUSIONS: This study has attempted to correlate that clinician's adaptability with an electronic record system that requires prior expertise in the use of computers. It recommends further foray into researching barriers associated with slow uptake and positive attitudinal change among clinicians using the electronic health records system in healthcare facilities across Saudi Arabia.

Background: Missed diagnosis of evolving or coexisting idiopathic (IIH) and spontaneous intracranial hypotension (SIH) is often the reason for persistent or worsening symptoms after foramen magnum decompression for Chiari malformation (CM) I. We explore the role of artificial intelligence (AI)/convolutional neural networks (CNN) in Chiari I malformation in a combinatorial role for the first time in literature, exploring both upstream and downstream magnetic resonance findings as initial screening profilers in CM-1. We have also put together a review of all existing subtypes of CM and discuss the role of upright (gravity-aided) magnetic resonance imaging (MRI) in evaluating equivocal tonsillar descent on a lying-down MRI. We have formulated a workflow algorithm MaChiP 1.0 (Manjila Chiari Protocol 1.0) using upstream and downstream profilers, that cause de novo or worsening Chiari I malformation, which we plan to implement using AI. Materials and Methods: The PRISMA guidelines were used for "CM and machine learning and CNN" on PubMed database articles, and four articles specific to the topic were encountered. The radiologic criteria for IIH and SIH were applied from neurosurgical literature, and they were applied between primary and secondary (acquired) Chiari I malformations. An upstream etiology such as IIH or SIH and an isolated downstream etiology in the spine were characterized using the existing body of literature. We propose the utility of using four selected criteria for IIH and SIH each, over MRI T2 images of the brain and spine, predominantly sagittal sequences in upstream etiology in the brain and multiplanar MRI in spinal lesions. Results: Using MaChiP 1.0 (patent/ copyright pending) concepts, we have proposed the upstream and downstream profilers implicated in progressive Chiari I malformation. The upstream profilers included findings of brain sagging, slope of the third ventricular floor, pontomesencephalic angle, mamillopontine distance, lateral ventricular angle, internal cerebral vein-vein of Galen angle, and displacement of iter, clivus length, tonsillar descent, etc., suggestive of SIH. The IIH features noted in upstream pathologies were posterior flattening of globe of the eye, partial empty sella, optic nerve sheath distortion, and optic nerve tortuosity in MRI. The downstream etiologies involved spinal cerebrospinal fluid (CSF) leak from dural tear, meningeal diverticula, CSF-venous fistulae, etc. Conclusion: AI would help offer predictive analysis along the spectrum of upstream and downstream etiologies, ensuring safety and efficacy in treating secondary (acquired) Chiari I malformation, especially with coexisting IIH and SIH. The MaChiP 1.0 algorithm can help document worsening of a previously diagnosed CM-1 and find the exact etiology of a secondary CM-I. However, the role of posterior fossa morphometry and cine-flow MRI data for intracranial CSF flow dynamics, along with advanced spinal CSF studies using dynamic myelo-CT scanning in the formation of secondary CM-I is still being evaluated.
RESUMEN
This study aims to highlight the challenges that undergraduates face when traveling a significant distance from home to study. These challenges are psychological, financial, and nutritional. The study was descriptive and based on a survey conducted to investigate the challenges faced by university students while studying away from their hometown. A questionnaire was used to collect data from 214 undergraduates between February and April 2021. The collected data were analyzed using the computer program SPSS version 24. Pearson's Chi-square and Fisher's exact tests were applied to observe associations between qualitative variables. A total of 214 undergraduates participated in the study, with a median age of 22 years. The study found significant relationships between weight change and housing (P < 0.001), weight change and distance (P < 0.001), level of homesickness and housing (P < 0.001), level of homesickness and college distance (P < 0.001), and financial status with housing (P = 0.025). The study revealed that a significant number of undergraduate participants face psychological, financial, and nutritional challenges. These challenges include psychosocial issues, such as homesickness financial difficulties, such as money issues, and nutritional concerns, such as weight changes.
RESUMEN
BACKGROUND AND OBJECTIVES: The preferred osmotic agent used for brain relaxation during craniotomies remains unclear, either mannitol (MAN) or hypertonic saline (HTS). Hence, we sought to compare these solutions in this population. METHODS: MEDLINE, Embase, and Cochrane databases were systematically searched until August 02, 2023. Data were examined using the Mantel-Haenszel method and 95% CIs. Heterogeneity was assessed using I2 statistics. Meta-regression analysis was conducted to evaluate a possible link between Brain Relaxation Score and tumor volume. R, version 4.2.3, was used for statistical analysis. RESULTS: A total of 16 randomized controlled trials and 1031 patients were included, of whom 631 (61%) underwent surgery for supratentorial tumor resection. Compared with MAN, HTS achieved better rates of brain relaxation (80% vs 71%; odds ratio [OR] 1.68; 95% CI 1.22-2.33; P = .001; I2 = 0%), which was also demonstrated in the subgroup analysis of patients with supratentorial brain tumor (78% vs 65%; OR 2.02; 95% CI 1.36-2.99; P = .0005; I2 = 0%); a minor number of patients requiring a second dose of osmotic agent (14% vs 28%; OR 0.43; 95% CI 0.27-0.69; P = .0003; I2 = 0%); a lower fluid intake (mean difference -475.9341 mL; 95% CI -818.8952 to -132.9730; P = .007; I2 = 88%); and lower urine output (mean difference -462.0941 mL; 95% CI -585.3020 to -338.8862; P = <.001; I2 = 96%). Hospital length of stay and focal neurological deficits did not reach a statistically significant difference between groups. CONCLUSION: In this updated meta-analysis, consistent results suggest that HTS is associated with more beneficial outcomes than MAN in patients undergoing craniotomy.

Spinal epidural lipomatosis (SEL) is a rare condition characterized by an excessive accumulation of adipose tissue in the spinal canal that can have a compressive effect on intraspinal neuroanatomical structures, leading to clinical symptoms. Several different conservative and surgical treatment strategies have been proposed but the treatment and outcomes remain controversial. There is a lack of severity-based evidence documenting the success of decompressive laminectomy in SEL and there are only anecdotal reports of clinico-radiological success with weight loss from bariatric surgery. This article demonstrates the resolution of SEL in two patients with bariatric surgery with the help of pre and postoperative MR imaging. The authors also highlight the classic "types" of spinal epidural lipomatosis with a surgically relevant grading system and elucidate the existence of concurrent extraspinal lipomatosis (i.e. mediastinal and intra-abdominal lipomatosis), drawing parallels with the natural history of SEL. The controversial question remains whether a symptomatic SEL patient needs a multilevel laminectomy for spinal decompression or bariatric surgery that can indirectly help the spinal condition. We propose that bariatric intervention could be better frontline management in patients with multifocal/multisystem lipomatosis (i.e., combined spinal and extraspinal) and spinal decompression would be ideal for those SEL patients with coexisting bony and/or ligamentous spinal canal or foraminal stenosis. This manuscript serves as a comprehensive and contemporary update on the radiological profile and two plausible treatment paths and will look toward further verification by a randomized clinical trial.
RESUMEN
Purely intradural retro-odontoid synovial cysts are rarely reported in neurosurgical literature, particularly in the absence of associated bony erosions. We present the case of a 57-year-old Native American male with a retro-odontoid synovial cyst and a history of chronic refractory neck pain that was adequately decompressed via an endoscopic-assisted far-lateral approach using a C1-2 hemilaminectomy, obviating the vertebral artery (VA) transposition, bony instability, and the need for instrumented bony fusion. The patient presented to our clinic with several months of refractory nuchal and cervical spine pain and crepitation affecting his activities of daily living (ADL). MRI findings revealed an intradural cyst at the level of C2 behind the odontoid process impinging on the medulla and causing early VA displacement. Both stereotactic neuro-navigation and microsurgical visualization aided in the manipulation of the endoscope and attaining the caudocranial working trajectory. The patient remained neurologically non-lateralizing postoperatively, similar to his preoperative status. This article highlights a less invasive surgical exposure with an endoscope-assisted caudocranial trajectory obtained by a limited unilateral hemilaminectomy to achieve the desired outcome.
RESUMEN
BACKGROUND: Both microsurgical and endovascular techniques continued to be treatment options for basilar apex aneurysms (BAA). We conducted a systematic review to compare both treatment options in terms of both clinical and radiological outcomes. METHODS: The PRISMA method was used to identify related articles. Data collected from each article and the two treatment approaches were compared in terms of favorable clinical outcome and complete/near complete occlusion rate. Subgroup analysis was done based on the size and the rupture status of BAA. RESULTS: Fifty-nine (59) and 32 articles reported a measurable clinical and radiological outcome respectively. The weighted average favorable clinical outcome was significantly higher in the endovascular group (86.4% vs 79.6%, P<0.0001), while the weighted average complete/near complete occlusion rate was significantly higher in the surgical group (92.6% vs 83.8%, P<0.0001). In the subgroup analysis, the favorable clinical outcome remained significantly higher in the endovascular group for the ruptured, unruptured and giant/large BAA (P<0.001), but not in the small BAA subgroup (P=0.26). The occlusion rate remained significantly higher in the surgical group for all subgroups (P<0.001). CONCLUSION: Treatment of BAA remains in a trade-off between favorable clinical outcome and complete or near-complete occlusion depending on the treatment modality selected. Careful selection of cases and judicial discussion between open surgical and endovascular team is warranted for treatment optimization.

Intraoperative MR imaging has become one of the most important concepts in present day neurosurgery. The brain shift problem with navigation, the need for assessment of the degree of resection and the need for detection of early postoperative complications were the three most important motives that drove the development of this technology. The GE Signa System with the "double doughnut" design was the world's first intraoperative MRI. From 1995 to 2007 more than 1,000 neurosurgical cases were performed with the system. The system was used by several different specialties and in neurosurgery it was most useful for complete resection of low-grade gliomas, identification and resection of small or deep metastases or cavernomas, recurrent pituitary adenomas, cystic tumors, biopsies in critical areas and surgery in recurrent GBM cases. Main superiorities of the system were the ability to scan without patient movement to get image updates, the ability to do posterior fossa cases and other difficult patient positioning, the easiness of operation using intravenous sedation anesthesia and the flexibility of the system to be used as platform for new diagnostic and therapeutic modalities.

OBJECTIVES: Evaluating treatment outcomes of local corticosteroid injections for work-related lower back pain (LBP) as the current evidence for the American College of Occupational and Environmental Medicine guidelines is considered insufficient to recommend this practice. MATERIAL AND METHODS: The authors conducted a retrospective study involving the patients who were treated with peri-articular and lower lumbar corticosteroid injections for work-related LBP at their occupational medicine clinic. RESULTS: Sixty-four patients met the inclusion criteria. The average pain level was reduced from M±SD 5.1±2.0 to M±SD 3.1±2.3 after the corticosteroid injection (p < 0.0001). Thirty-five patients (55%) were discharged to regular duty; 23 (36%) were transferred to orthopedics due to persistent pain; and 6 (9%) were lost to follow-up. CONCLUSIONS: Corticosteroid injections for work-related LBP are effective in reducing pain and enhancing discharge to regular duty. Nonetheless, larger prospective trials are needed to validate these findings. Int J Occup Med Environ Health. 2021;34(1):111-20.

BACKGROUND: Aneurysmal subarachnoid hemorrhage (aSAH) is associated with disproportionally high mortality and long-term neurological sequelae. Management of patients with aSAH has changed markedly over the years, leading to improvements in outcome. OBJECTIVE: To describe trends in aSAH care and outcome in a high-volume single center 15-yr cohort. METHODS: All new admissions diagnosed with subarachnoid hemorrhage (SAH) to our tertiary neuro-intensive care unit between 2002 and 2016 were reviewed. Trend analysis was performed to assess temporal changes and a step-wise regression analysis was done to identify factors associated with outcomes. RESULTS: Out of 3970 admissions of patients with SAH, 2475 patients proved to have a ruptured intracranial aneurysm. Over the years of the study, patient acuity increased by Hunt & Hess (H&H) grade and related complications. Endovascular therapies became more prevalent over the years, and were correlated with better outcome. Functional outcome overall improved, yet the main effect was noted in the low- and intermediate-grade patients. Several parameters were associated with poor functional outcome, including long-term mechanical ventilation (odds ratio 11.99, CI 95% [7.15-20.63]), acute kidney injury (3.55 [1.64-8.24]), pneumonia (2.89 [1.89-4.42]), hydrocephalus (1.80 [1.24-2.63]) diabetes mellitus (1.71 [1.04-2.84]), seizures (1.69 [1.07-2.70], H&H (1.67 [1.45-1.94]), and age (1.06 [1.05-1.07]), while endovascular approach to treat the aneurysm, compared with clip-ligation, had a positive effect (0.35 [0.25-0.48]). CONCLUSION: This large, single referral center, retrospective analysis reveals important trends in the treatment of aSAH. It also demonstrates that despite improvement in functional outcome over the years, systemic complications remain a significant risk factor for poor prognosis. The historic H&H determination of outcome is less valid with today's improved care.

BACKGROUND: Uncommon diseases are usually not suspected at initial presentation, and the diagnosis might be challenging. Here we present a rare disease diagnosed in a work-related injury setting, highlighting the importance of further investigation by means of a more detail physical exam, imaging studies and involvement of other specialties. CASE PRESENTATION: A 21-year-old Hispanic male, who is a food service worker, presented following a work-related right elbow contusion with severe pain to his right elbow associated with swelling and purplish-red bruising/discoloration on its medial side and forearm. Physical exam demonstrated swelling, tenderness, and conspicuous dilated blood vessels across the right arm and forearm; additionally, multiple red-purplish scattered patches were found on the right arm, anterior and posterior right upper chest. His past medical history was significant for Capillary Hemangioma. He was initially treated conservatively and with work restriction; however, the pain in the forearm persisted. CT angiogram showed multiple interweaving vascular structures on the forearm, and further imaging by MR angiography depicted multiple vascular malformations in the right upper extremity and chest. Vascular surgery was consulted, and the diagnosis of Klippel-Trenaunay syndrome was made. CONCLUSIONS: Klippel-Trenaunay syndrome is a rare congenital disorder that could present in a wide-range of signs and symptoms. Thorough history taking and clinical examination is warranted in any work-related injuries. Further work up and referral to specialist should always be considered when diagnosis is unclear, or when initial symptoms do not resolve with treatment.
RESUMEN
BACKGROUND: Tarlov cyst disease is a collection of cerebrospinal fluid between the endoneurium and perineurium of spinal, usually sacral, nerve roots. These cysts can become symptomatic in 20% of patients, causing lower back pain, radiculopathy, bladder and bowel dysfunction necessitating medical or surgical intervention. Different surgical and non-surgical modalities have been described for the treatment of symptomatic Tarlov cysts. However, there has been no published study that examined types of surgical techniques side by side. Our study presents a preliminary experience in the surgical management of symptomatic Tarlov cysts using two surgical techniques: cyst fenestration and nerve root imbrication. METHODS: Retrospective chart review and analysis was done for all patients who underwent surgical intervention for symptomatic Tarlov cyst(s) in the period 2007-2013. Operative reports, preoperative and postoperative clinic visit reports were reviewed. The surgical techniques of cyst fenestration and nerve root imbrication were each described in terms of intraoperative parameters, hospital course and outcome. Modified MacNab criteria were used for evaluation of the final clinical outcome. RESULTS: Thirty-six surgical patients were identified. Three had repeat surgery (total of 39 operations). The median age was 51 years (range, 26-84 years). Eighty-six percent were females. The presenting symptoms were low back pain (94%), sensory radiculopathy (69%), bladder and bowel dysfunction (61%), sexual dysfunction (17%) and motor dysfunction (8%). Cyst fenestration was performed in 12 patients (31%) and nerve root imbrication was done in 27 (69%). All patients in the fenestration group but only 67% in the imbrication group had fibrin glue injection into the cyst or around the reconstructed nerve root. The overall surgery-related complication rate was 28%. The complication rate was 5/12 (42%) in the fenestration group and 6/27 (22%) in the imbrication group. At the time of the last clinic visit, improved clinical outcome was noted in 9/11 (82%) and 20/25 (80%) in the fenestration and the imbrication group, respectively. CONCLUSIONS: Cyst fenestration and nerve root imbrication are both surgical techniques to treat symptomatic Tarlov cyst(s), and both can result in clinical improvement.
RESUMEN
CONTEXT: An accelerated approach to popularize complementary and alternative medicine (CAM) in healthcare services has led to the need to assess medical students' knowledge of CAM. Furthermore, their attitude toward its efficacy and usage will determine its growing popularity in healthcare. Another key idea is to integrate CAM with conventional medical teaching to make it a part of the mainstream medical curriculum. The objectives were to assess the medical students' perceptions about integrating CAM with conventional medicine and to assess the attitude of prescribing different CAM modalities to patients presenting with a particular disease or health disorder. SETTINGS AND DESIGN: This is a descriptive, institutional based study conducted on undergraduate 3rd year medical students. MATERIALS AND METHODS: Data were collected by a structured and pretested questionnaire to be filled in by the participants in the presence of the investigator. Statistical data were entered in SPSS software, and descriptive analysis was conducted. RESULTS: Most of the students (74%) agreed that conventional and CAM therapy can be integrated to achieve a better health care outcome. Forty-eight percent of the participants were positive that knowledge of CAM is important since many patients still prefer this option, particularly for chronic illnesses. CONCLUSIONS: The students were receptive to the introduction of a new treatment method in their curriculum, which although unconventional, presents an alternative and traditional form of treatment even if it does not have major backing from the scientific community. The participants felt that more knowledge is required to make an informed opinion about its usefulness to the community as a whole.
RESUMEN
BACKGROUND: Evidently, complementary and alternative medicine (CAM) is a recognized medical practice that efficiently uses multiple treatment therapies and techniques in the prevention and management of a variety of human disorders. Many medical schools have integrated CAM curriculum in medical education system worldwide. Research in knowledge, attitude, and practice (KAP) of diverse health professionals exposed to CAM courses is important from many perspectives including improvement in KAP and teaching skills of faculty, together with capacity building and curriculum development. OBJECTIVE AND SETTING: This pre- and post-design cross-sectional study aimed to assess CAM-KAP of two intakes of medical students in Majmaah University, Saudi Arabia. METHODS: The second-year medical students of the first (year 2012-2013) and second (year 2013-2014) intake (n=26 and 39, respectively) were selected for this study. A reliable, 16-item self-administered questionnaire was distributed among all the students for answering before and after the 48-hour CAM course. The data were analyzed using appropriate statistical test of significance. RESULTS: Medical students' knowledge and attitude toward CAM significantly improved across some subitems of CAM questionnaire with a positive trend in the rest of its items including their views on CAM practices. CONCLUSION: CAM course tends to have a positive impact on KAP of medical students. The preliminary results of this study call for further research with a larger sample in academic settings across the nation.
