Complete resection versus functional preservation in resection of cystic vestibular schwannoma in a 56-year-old female: case report and literature review.

Surgery for vestibular schwannoma presents unique challenges to the surgeon, given that the primary objectives are achieving complete resection while preserving both facial nerve and hearing function. Consequently, a comprehensive preoperative and perioperative assessment of the tumor is essential to determine its extent, particularly in cases involving dumbbell-shaped lesions. This case report describes our experience in managing a patient with a dumbbell-shaped vestibular schwannoma, where we achieved near-total resection while successfully preserving the patient's facial nerve and hearing function. The early postoperative evaluation revealed no morbidity, and the patient experienced a significant improvement in their symptoms.

Coffee and tea consumption and the risk of glioma: a systematic review and dose-response meta-analysis.

In this systematic review and dose-response meta-analysis, we aimed to assess whether coffee and tea consumption is related to the risk of glioma. We performed a systematic literature search using PubMed, Embase, Scopus and the EuropePMC from the inception of database up until 1 October 2020. Exposures in the present study were coffee and tea consumption, the main outcome was the incidence of glioma. The present study compares the association between the exposure of coffee and tea with the incidence of glioma, and the results are reported in relative risks (RR). There are 12 unique studies comprising of 1 960 731 participants with 2987 glioma cases. Higher coffee consumption was associated with a statistically non-significant trend towards lower risk of glioma (RR 0·77 (95 % CI 0·55, 1·03), P= 0·11; I2:75·27 %). Meta-regression showed that the association between coffee and glioma was reduced by smoking (P= 0·029). Higher tea consumption was associated with a lower risk of glioma (RR 0·84 (95 % CI 0·71, 0·98), P= 0·030; I2:16·42 %). Sensitivity analysis by removal of case-control studies showed that higher coffee consumption (RR 0·85 (95 % CI 0·72, 1·00), P= 0·046; I2:0 %) and higher tea consumption (RR 0·81 (95 % CI 0·70, 0·93), P= 0·004; I2:0 %, Pnon-linearity = 0·140) were associated with lower risk of glioma. Dose-response meta-analysis showed that every one cup of coffee per day decreases the risk of glioma by 3 % (RR 0·97 (95 % CI 0·94, 0·99), P= 0·016, Pnon-linearity = 0·054) and every one cup of tea per day decreases the risk of glioma by 3 % (RR 0·97 (95 % CI 0·94, 1·00), P= 0·048). This meta-analysis showed apparent association between coffee and tea intake and risk of glioma.

Transcranial approach as surgical treatment for giant pituitary adenoma during COVID 19 pandemic - What can we learn?: A case report.

INTRODUCTION: In the COVID 19 pandemic, pituitary surgery is one of challenging surgical treatment, especially the involving transsphenoid approach. It was reported that the aerosolisation and mucosal involvement increase the risk of viral transmission during operation. Therefore, transcranial is a safer surgical approach during COVID-19 pandemic. This study aimed to reported transcranial approach to treat giant pituitary adenoma with aggressive visual disturbance which require urgent surgical management. CASE PRESENTATION: We reported a 21-year old male, who required urgent surgery because of progressive visual disturbance due to giant pituitary adenoma. On brain MRI with contrast, it was revealed an extraaxial tumor extending anteriorly over plannum sphenoidal with the greatest diameter was 5.34 cm. Transcranial approach was chosen to resect the tumor. Near total removal of the tumor was achieved without damaging vital neurovascular structure. The visual acuity was improved and no significant postoperative complication. Pathology examination revealed pituitary adenoma. CONCLUSION: Transcranial surgery for pituitary adenoma is still an armamentarium in neurosurgical practice, especially in the COVID 19 pandemic to provide safer surgical approach.

Traumatic Subacute Spinal Subdural Hematoma Concomitant with Symptomatic Cranial Subdural Hematoma: Possible Mechanism.

BACKGROUND: Spinal subdural hematoma (SDH) concomitant with cranial SDH is extremely rare. Although some theories have been proposed, the pathophysiology underlying this condition remains unclear. We present a case of traumatic subacute spinal SDH followed by symptomatic subacute cranial SDH. CASE DESCRIPTION: A 56-year-old woman was admitted with severe back pain 2 weeks after sustaining a minor head injury. The pain was worse with walking or standing and was relieved a little bit by sitting. There was no clinical evidence of back injury. There was no neurologic deficit. Magnetic resonance imaging of the spine showed subacute spinal SDH from T12 to S1. Owing to progressive worsening of back pain, bilateral laminectomy of L1-S1 and drainage of subacute spinal SDH were performed. The pain was completely relieved after surgery. On postoperative day 4, the patient was noted to be unconscious with Glasgow Coma Scale score of 10 (E2V3M5). Computed tomography scan of the head showed subacute bilateral cranial SDH. Burr hole drainage was performed. The patient experienced a complete recovery. CONCLUSIONS: This case suggests the possibility that spinal SDH can develop as a result of cranial SDH migration to the most dependent spinal subdural space. The physician should be aware of the possibility of symptomatic cranial SDH developing following spinal SDH evacuation.

S100B Serum Level as a Mortality Predictor for Traumatic Brain Injury: A Meta-Analysis.

BACKGROUND: The pathogenesis of inflammatory neuronal cell damage will continue after traumatic brain injury in which contributed to subsequent mortality. Serum S100B levels were shown to be an early predictor of mortality due to traumatic brain injury. AIM: This Meta-Analysis will analyse the mean and diagnostic strength of serum S100B levels between survived and died subjects with head injuries based on the various follow-up times of nine studies. METHODS: We conducted a meta-anelysis in accordance with PRISMA guidelines and adhering to Cochrane Handbook for Systematic Review of Interventions. Literature search was conducted on March 16, 2018 from Medline and Scopus in the past 10 years, using various keywords related to S100, brain injury, and outcome. Duplicate journals were sorted out via EndNote. Included articles were as follows: original data from the group, clinical trials, case series, patients undergoing serum S100B levels with both short- and long-term follow-up mortality. Data were collected for mortality, serum S100B levels, and its diagnostic strength. All data were analyzed using Review Manager 5.3 (Cochrane, Denmark). RESULTS: The results of the meta-analysis showed a significant difference in S100B levels between survived and died subjects with head injuries on overall follow-up timeline (0.91, 95.9% CI 0.7-1.12, I2 = 98%, p < 0.001), during treatment (1.43, 95% CI 0.97 to 1.89, I2 = 98%, p < 0.001), or 6 months (0.19; 95%CI 0.1-0.29, I2 = 76%, p < 0.001) with an average threshold value that varies according to the study method used. The mean diagnostic strength was also promising to predict early mortality (sensitivity of 77.18% and 92.33%, specificity of 78.35% and 50.6%, respectively). CONCLUSION: S100B serum levels in the future will be potential biomarkers, and it is expected that there will be standardised guidelines for their application.

Modified Revised Trauma-Marshall score as a proposed tool in predicting the outcome of moderate and severe traumatic brain injury.

BACKGROUND: Traumatic brain injury (TBI) is a common healthcare problem related to disability. An easy-to-use trauma scoring system informs physicians about the severity of trauma and helps to decide the course of management. The purpose of this study is to use the combination of both physiological and anatomical assessment tools that predict the outcome and develop a new modified prognostic scoring system in TBIs. PATIENTS AND METHODS: A total of 181 subjects admitted to the emergency department (ED) of Sanglah General Hospital were documented for both Marshall CT scan classification score (MCTC) and Revised Trauma Score (RTS) upon admission. Glasgow Outcome Scale (GOS) was then documented at six months after brain injury. A new Modified Revised Trauma-Marshall score (m-RTS) was developed using statistical analytic methods. RESULTS: The total sample enrolled for this study was 181 patients. The mean RTS upon admission was 10.2±1.2. Of the 181 subjects, 110 (60.8%) were found to have favorable GOS (GOS score >3). Best Youden's index results were obtained with any of the RTS of ≤10 with area under receiver operating characteristic (ROC) curve of 0.2542 and with risk ratio of 2.9 (95% CI=1.98-4.28; P=0.001); and Marshall score ≤2 with area under ROC curve of 0.2249 with risk ratio of 3.9 (95% CI=2.52-5.89; P=0.001). The RTS-Marshall combination has higher sensitivity with risk ratio of 4.5 (CI 95%=2.55-8.0; P=0.001) for screening tools of unfavorable outcome. The Pearson's correlation between RTS and Marshall classification is 0.464 (P<0.001). CONCLUSION: Combination of physiological and anatomical score improves the prognostic of outcome in moderate and severe TBI patients, formulated in this accurate, simple, applicable and reliable m-RTS prognostic score model.

Management of unusual dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease) in a developing country: Case report and review of the literature.

Dysplastic cerebellar gangliocytoma or Lhermitte-Duclos disease (LDD) especially in children are extremely rare. In this report we add one further case to this rare entity. A three year old boy with a history of cerebellar and brain stem compression signs was presented in unconscious condition. Computerized tomography (CT) scan revealed a well defined lesion mixed with area of calcification in the right cerebellum and severe obstructive hydrocephalus. Ventricular shunting was performed followed by gross total tumor removal three days after shunting. In the follow up period, the patient showed almost total resolution of all neurological deficits. MRI has been an imaging tool to preoperatively diagnose this disease; otherwise it would be uncertain preoperative diagnosis. However, in this report we would like to emphasize that not all uncertain diagnosis of LDD leads to palliative treatment. Well demarcated lesion may account for the safe surgical resection of this disease.

Final results of MRC CRASH, a randomised placebo-controlled trial of intravenous corticosteroid in adults with head injury-outcomes at 6 months.

MRC CRASH is a randomised controlled trial (ISRCTN74459797) of the effect of corticosteroids on death and disability after head injury. We randomly allocated 10,008 adults with head injury and a Glasgow Coma Scale score of 14 or less, within 8 h of injury, to a 48-h infusion of corticosteroid (methylprednisolone) or placebo. Data at 6 months were obtained for 9673 (96.7%) patients. The risk of death was higher in the corticosteroid group than in the placebo group (1248 [25.7%] vs 1075 [22.3%] deaths; relative risk 1.15, 95% CI 1.07-1.24; p=0.0001), as was the risk of death or severe disability (1828 [38.1%] vs 1728 [36.3%] dead or severely disabled; 1.05, 0.99-1.10; p=0.079). There was no evidence that the effect of corticosteroids differed by injury severity or time since injury. These results lend support to our earlier conclusion that corticosteroids should not be used routinely in the treatment of head injury.
