Short- and long-term outcome and predictors in an international cohort of patients with neuro-COVID-19.

BACKGROUND AND PURPOSE: Despite the increasing number of reports on the spectrum of neurological manifestations of COVID-19 (neuro-COVID), few studies have assessed short- and long-term outcome of the disease. METHODS: This is a cohort study enrolling adult patients with neuro-COVID seen in neurological consultation. Data were collected prospectively or retrospectively in the European Academy of Neurology NEuro-covid ReGistrY ((ENERGY). The outcome at discharge was measured using the modified Rankin Scale and defined as 'stable/improved' if the modified Rankin Scale score was equal to or lower than the pre-morbid score, 'worse' if the score was higher than the pre-morbid score. Status at 6 months was also recorded. Demographic and clinical variables were assessed as predictors of outcome at discharge and 6 months. RESULTS: From July 2020 to March 2021, 971 patients from 19 countries were included. 810 (83.4%) were hospitalized. 432 (53.3%) were discharged with worse functional status. Older age, stupor/coma, stroke and intensive care unit (ICU) admission were predictors of worse outcome at discharge. 132 (16.3%) died in hospital. Older age, cancer, cardiovascular complications, refractory shock, stupor/coma and ICU admission were associated with death. 262 were followed for 6 months. Acute stroke or ataxia, ICU admission and degree of functional impairment at discharge were predictors of worse outcome. 65/221 hospitalized patients (29.4%) and 10/32 non-hospitalized patients (24.4%) experienced persisting neurological symptoms/signs. 10/262 patients (3.8%) developed new neurological complaints during the 6 months of follow-up. CONCLUSIONS: Neuro-COVID is a severe disease associated with worse functional status at discharge, particularly in older subjects and those with comorbidities and acute complications of infection.

Evaluating pituitary adenomas using national research databases: systematic review of the quality of reporting based on the STROBE scale.

The use of national research databases has become more prevalent for studying various neurosurgical diseases. Despite the advantages of using large databases to glean clinical insight, variation remains in the methodology and reporting among studies. Using STROBE and RECORD guidelines, we evaluated the quality of reporting of the database literature investigating surgical management of benign pituitary adenomas. In this systematic review of the PubMed/MEDLINE database, we identified studies employing large national research databases of patients who underwent surgery for benign pituitary adenoma. We evaluated each of these studies using the STROBE-RECORD reporting guideline criteria to assess their quality. A total of 42 studies from 2003 to 2020 were identified for inclusion. The two raters demonstrated a κ = 0.228 with 84% overall agreement. Commonly underreported criteria included bias (discussed in 56% of studies), main result reporting (70%), subgroup analysis (69%), generalizability (68%), and funding (57%). These factors, in addition to the data sources/measurement criteria, also had the largest discrepancies between reviewers. About 20% of administrative database reviews did not accurately address bias or control for confounding variables. We found frequent underreporting of crucial information and criteria that can be challenging to identify may limit large database studies of pituitary adenomas. Improved reporting of certain criteria is critical to optimize reader understanding of large database studies. This would allow better dissemination and implementation of study findings, especially as the use of these research tools increases.

Clinical, sinonasal, and long-term smell and taste outcomes in mildly symptomatic COVID-19 patients.

INTRODUCTION: Coronavirus 2019 disease (COVID-19) has variable clinical, sinonasal, and smell/taste outcomes. METHODS: Observational study was conducted at a tertiary hospital in Amman, Jordan. Demographic data, clinical presentation and smoking status were collected. Sinonasal symptoms, using Sino-Nasal Outcome Test (SNOT-22) Questionnaire, were evaluated. Smell/taste dysfunction was followed for three months. RESULTS: Ninety-Seven patients had satisfactory responses. Eighty-six patients were symptomatic (41 at presentation, and 45 during admission). Among those patients, 59.3% had cough, 52.3% sore throat and 48.8% fever. The most common initial symptom was sore throat. Shortness of breath and smell/taste dysfunction were significantly higher in females. Surprisingly, shortness of breath was more common in non-smokers. Smell/taste dysfunction affected 25.6% of patients, but was the first symptom in only one patient. Fourteen of 22 symptoms in SNOT-22 had significant increase. The overall average of symptoms scores increased from 0.472 to 1.034, with smell/taste dysfunction to have the most increment. The latter symptom recovered completely in 81% and dysgeusia developed in 9.5% at three months, and it recovered completely in all patients at six months. CONCLUSION: Although COVID-19 may produce severe lower airways disease, it has modest effect on nose and paranasal sinuses. Moreover, smell/taste dysfunction is a prominent symptom, but it usually recovers dramatically.

Fruit and vegetable consumption and cardiovascular diseases among Jordanians: a case-control study.

OBJECTIVES: Fruit and vegetable intake has been reported as one of the significant protective factors against the development of cardiovascular diseases (CVD). This study aimed to assess the possible preventive effect of fruit and vegetable consumption on developing CVD. METHODS: A total of 398 participants (205 cases and 193 controls) referred for elective coronary angiography with clinical suspicion of coronary artery disease to Prince Hamza Hospital in Amman were enrolled in this case-control study. Dietary data were collected separately from each patient using interview-based food frequency questionnaire. RESULTS: The findings of the present study revealed that a total consumption of 3 servings of vegetable per day decreased significantly the risk of CVD to about 54% (OR = 0.46, 95% CI: 0.22-0.97, p = 0.033). Consumption of banana was found to reduce the risk of CVD to about 44% and 62% when consuming 1-2 and 3-6 servings/week, respectively, with p-value for trend 0.004. For the vegetables, the consumption of grape leaves and stuffed vegetables in general was significantly associated with lower risk of CVD. Increasing cauliflower consumption of 1-2 servings per week decreased CVD risk to about 37% (OR = 0.63, 95% CI: 0.38-0.98). Consuming up to 3-6 servings per week of mixed vegetables (OR = 0.10, 95% CI: 0.01-0.83) and onion (OR = 0.42, 95% CI: 0.22-0.80) revealed an inverse association with CVD development. CONCLUSIONS: Adding to the present evidence, consumption of some fruits and vegetables could be considered as preventive factor against developing CVD. However, the association of consuming vegetables with preventing CVD was higher than the fruit consumption.

Effect of patient age on glioblastoma perioperative treatment costs: a value driven outcome database analysis.

INTRODUCTION: Identification of groups of patients or interventions with higher associated treatment costs may be beneficial in efforts to decrease the overall financial burden of glioblastoma (GBM) treatment. The authors' objective was to evaluate perioperative surgical treatment cost differences between elderly and nonelderly patients with GBM using the Value Driven Outcome (VDO) database. METHODS: The authors obtained data from a retrospective cohort of GBM patients treated surgically (resection or biopsy) at their institution from August 2011 to February 2018. Data were compiled using medical records and the VDO database. RESULTS: A total of 181 patients with GBM were included. Patients were grouped into age < 70 years at time of surgery (nonelderly; n = 121) and ≥ 70 years (elderly; n = 60). Costs were approximately 38% higher in the elderly group on average (each patient was mean 0.68% of total cohort cost vs. 0.49%, p = 0.044). Higher age significantly, but weakly, correlated with higher treatment cost on linear regression analysis (p = 0.007; R2 = 0.04). Length of stay was significantly associated with increased cost on linear regression (p < 0.001, R2 = 0.84) and was significantly longer in the elderly group (8.7 ± 11.3 vs. 5.2 ± 4.3 days, p = 0.025). The cost breakdown by facility, pharmacy, supply/implants, imaging, and laboratory costs was not significantly different between age groups. Elderly patients with any postoperative complication had 2.1 times greater total costs than those without complication (p = 0.094), 2.9 times greater total costs than nonelderly patients with complication (p = 0.013), and 2.3 times greater total costs than nonelderly patients without complication (p = 0.022). CONCLUSIONS: GBM surgical treatment costs are higher in older patients, particularly those who experience postoperative complications.

Clinical potential of meningioma genomic insights: a practical review for neurosurgeons.

Meningiomas are among the most common intracranial pathological conditions, accounting for 36% of intracranial lesions treated by neurosurgeons. Although the majority of these lesions are benign, the classical categorization of tumors by histological type or World Health Organization (WHO) grade has not fully captured the potential for meningioma progression and recurrence. Many targeted treatments have failed to generate a long-lasting effect on these tumors. Recently, several seminal studies evaluating the genomics of intracranial meningiomas have rapidly changed the understanding of the disease. The importance of NF2 (neurofibromin 2), TRAF7 (tumor necrosis factor [TNF] receptor-associated factor 7), KLF4 (Kruppel-like factor 4), AKT1, SMO (smoothened), PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha), and POLR2 (RNA polymerase II subunit A) demonstrates that there are at least 6 distinct mutational classes of meningiomas. In addition, 6 methylation classes of meningioma have been appreciated, enabling improved prediction of prognosis compared with traditional WHO grades. Genomic studies have shed light on the nature of recurrent meningioma, distinct intracranial locations and mutational patterns, and a potential embryonic cancer stem cell-like origin. However, despite these exciting findings, the clinical relevance of these findings remains elusive. The authors review the key findings from recent genomic studies in meningiomas, specifically focusing on how these findings relate to clinical insights for the practicing neurosurgeon.

Risk factors for coronary artery disease in patients undergoing elective coronary angiography in Jordan.

BACKGROUND: Unhealthy lifestyle factors such as smoking, obesity, inactivity and type 2 diabetes are endemic in the Middle East. The public health consequences might be detrimental; however, local studies on risk factors for coronary artery disease (CAD) are scarce. METHODS: Patients referred for coronary angiography at a tertiary hospital in Amman, Jordan, between January and December 2015, were included in this study. Risk factors for CAD were assessed in a multivariate logistic regression model, and presented as odds ratio (OR) with 95% confidence interval (CI). RESULTS: Among 557 participants, 356 (63.9%) had CAD and 201 (36.1%) had a normal cardiogram. The majority (n = 395, 70.9%) were male, and median age was 55 years (interquartile range 47-64). Two-hundred-and-fifteen (38.6%) individuals reported previous diabetes, and 287 (51.5%) were current or previous smokers. In multivariate analysis, male gender (OR 3.7, 95% CI 2.3-6.0), age (45-54 years: OR 4.8, 95% CI 2.7-8.5; 55-64 years: OR 6.0, 95% CI 3.2-11.4; ≥65 years: OR 15.7, 95% CI 7.8-31.3), previous diabetes (OR 2.6, 95% CI 1.7-4.1) and current/previous smoking (OR 2.1, 95% CI 1.3-3.4) were significant predictors of CAD. CONCLUSIONS: Age, gender, diabetes and smoking were strong and significant risk factors for CAD in Jordan. Public health interventions to reduce the prevalence of smoking and diabetes are urgently needed.

Nano-Enriched and Autonomous Sensing Framework for Dissolved Oxygen.

This paper investigates a nano-enhanced wireless sensing framework for dissolved oxygen (DO). The system integrates a nanosensor that employs cerium oxide (ceria) nanoparticles to monitor the concentration of DO in aqueous media via optical fluorescence quenching. We propose a comprehensive sensing framework with the nanosensor equipped with a digital interface where the sensor output is digitized and dispatched wirelessly to a trustworthy data collection and analysis framework for consolidation and information extraction. The proposed system collects and processes the sensor readings to provide clear indications about the current or the anticipated dissolved oxygen levels in the aqueous media.

The LWDS-10J: reliability and validity of the Lebanon Waterpipe Dependence Scale among university students in Jordan.

INTRODUCTION: While the Lebanon Waterpipe Dependence Scale (LWDS-11) has shown promise in assessing dependence on waterpipe tobacco smoking (WTS) in Lebanon among adult users, it would be valuable to identify WTS addiction earlier and to explore reliability and validity of these items in other populations. METHODS: In 2010-2012, we conducted a multiyear survey of 5,853 students from 4 Jordanian universities. We measured WTS, sociodemographic data, and the LWDS-11 items. We conducted exploratory factor analysis with half of the sample and confirmed the resulting model using confirmatory factor analysis with the other half. We examined construct validity with regression models assessing associations between the modified scale and 5 constructs conceptually expected to be associated with dependence. RESULTS: WTS rates were 35% in the past 30 days and 56% ever. Principal-components analysis of LWDS items in the first half of the sample yielded 10 items representing 3 factors labeled physical dependence, relaxation/pleasure, and social aspects. Cronbach's α was .77 for the total scale and was .75, .70, and .67 for each individual subscale. Confirmatory factor analysis in a structural equation modeling framework confirmed good fit (root mean squared error of approximation = 0.068, and comparative fit index = 0.937). Dependence according to the resulting scale (LWDS-10J) was strongly associated with each of the 5 expected constructs, whether the dependent variable was treated as categorical or continuous. CONCLUSIONS: The LWDS-11 items exhibited a different factor structure in our sample. However, the modified scale (LWDS-10J) showed promising reliability and construct validity in this population.

Ossifying fibroma of the ethmoid and sphenoid sinuses: A report of a rare case and literature review.

Background: Fibro-osseous lesions include a variety of bone lesions with different clinical and histopathological features. Case Description: We report a case of cemento-ossifying lesion involving the left ethmoid and sphenoid sinus in a 17-year-old male patient. Computed tomography showed an expansile hyperdense lesion with sclerosed peripheral mantle epicentered on the left ethmoid and sphenoid sinus and extending into the left nasal cavity. Magnetic resonance imaging was done for preoperative planning. Transnasal endoscopic resection was performed and histopathological examination confirmed the diagnosis of ossifying fibroma (OF). Conclusion: Involvement of the ethmoid sinus with OF is a rare condition; therefore, we examined the literature for similar cases to highlight the possible clinical presentation and management. Endoscopic management is a safe, effective approach with a low rate of complications.

Venous sinus stenting for idiopathic intracranial hypertension: An updated Meta-analysis.

BACKGROUND: Idiopathic intracranial hypertension (IIH) is characterized by elevated intracranial pressure and primarily affects obese women of reproductive age. Venous sinus stenting (VSS) is a surgical procedure used to treat IIH, but its safety and efficacy are still controversial. METHODS: A systematic review and meta-analysis were conducted following PRISMA guidelines. Multiple databases were searched for studies evaluating the safety and efficacy of VSS in IIH patients and meta-analysis was performed to pool the data. RESULTS: A total of 36 studies involving 1066 patients who underwent VSS were included. After VSS, a significant reduction in trans-stenotic gradient pressure was observed. Patients also showed significantly lower cerebrospinal fluid (CSF) opening pressure. Clinical outcomes demonstrated improvement in tinnitus (95%), papilledema (89%), visual disturbances (88%), and headache (79%). However, 13.7% of patients experienced treatment failure or complications. The treatment failure rate was 8.35%, characterized by worsening symptoms and recurrence of IIH. The complications rate was 5.35%, including subdural hemorrhage, urinary tract infection, stent thrombus formation, and others. CONCLUSION: VSS appears to be a safe and effective treatment option for IIH patients who are unresponsive to medical therapy or have significant visual symptoms. However, long-term outcomes and safety of the procedure require further investigation.

Subtemporal Approach for the Treatment of Ruptured and Unruptured Distal Basilar Artery Aneurysms: Is There a Contemporary Use?

BACKGROUND AND OBJECTIVES: Distal basilar artery aneurysms (DBAs) are high-risk lesions for which endovascular treatment is preferred because of their deep location, yet indications for open clipping nonetheless remain. The subtemporal approach allows for early proximal control and direct visualization of critical posterior perforating arteries, especially for posterior-projecting aneurysms. Our objective was to describe our clinical experience with the subtemporal approach for clipping DBAs in the evolving endovascular era. METHODS: This was a retrospective, single-institution case series of patients with DBAs treated with microsurgery over a 21-year period (2002-2023). Demographic, clinical, and surgical data were collected for analysis. RESULTS: Twenty-seven patients underwent clipping of 11 ruptured and 16 unruptured DBAs with a subtemporal approach (24 female; mean age 53 years). Ten patients had expanded craniotomies for treatment of additional aneurysms. The aneurysm occlusion rate was 100%. Good neurological outcomes as defined by the modified Rankin Scale score ≤2 and Glasgow Outcome Scale score ≥4 were achieved in 21/27 patients (78%). Two patients died before hospital discharge, one from vasospasm-induced strokes and another from an intraoperative myocardial infarction. CONCLUSION: These results demonstrate that microsurgical clip ligation of DBAs using the subtemporal approach remains a viable option for complex lesions not amenable to endovascular management.

The role of surgical management for prolactin-secreting tumors in the era of dopaminergic agonists: An international multicenter report.

OBJECTIVE: First-line prolactin-secreting tumor (PST) management typically involves treatment with dopamine agonists and the role of surgery remains to be further explored. We examined the international experience of 12 neurosurgical centers to assess the patient characteristics, safety profile, and effectiveness of surgery for PST management. METHODS: Patients surgically treated for PST from January 2017 through December 2020 were evaluated for surgical characteristics, outcomes, and safety. RESULTS: Among 272 patients identified (65.1% female), the mean age was 38.0 ± 14.3 years. Overall, 54.4% of PST were macroadenomas. Minor complications were seen in 39.3% of patients and major complications were in 4.4%. The most common major complications were epistaxis and worsened vision. Most minor complications involved electrolyte/sodium dysregulation. At 3-6 months, local control on imaging was achieved in 94.8% of cases and residual/recurrent tumor was seen in 19.3%. Reoperations were required for 2.9% of cases. On multivariate analysis, previous surgery was significantly predictive of intraoperative complications (6.14 OR, p < 0.01) and major complications (14.12 OR, p < 0.01). Previous pharmacotherapy (0.27 OR, p = 0.02) and cavernous sinus invasion (0.19 OR, p = 0.03) were significantly protective against early endocrinological cure. Knosp classification was highly predictive of residual tumor or PST recurrence on 6-month follow-up imaging (4.60 OR, p < 0.01). There was noted institutional variation in clinical factors and outcomes. CONCLUSION: Our results evaluate a modern, multicenter, global series of PST. These data can serve as a benchmark to compare with DA therapy and other surgical series. Further study and longer term outcomes could provide insight into how patients benefit from surgical treatment.

Exposure of pregnant women to waterpipe and cigarette smoke.

INTRODUCTION: Throughout the Eastern Mediterranean region, tobacco is used primarily in 2 forms: cigarette smoking and waterpipe smoking. Despite the fact that tobacco use is considered as a global public health threat, waterpipe smoking is reported to be growing in popularity, particularly among women. The objectives of this study are to determine the prevalence and patterns of cigarette, waterpipe, and passive smoking among pregnant women in Jordan, and to assess their perception of harmful effects of cigarette and waterpipe smoking. METHODS: A total of 500 pregnant women were randomly recruited from maternity clinics in North and Middle of Jordan and surveyed regarding exposure to waterpipe tobacco and cigarette smoking. RESULTS: The results showed that 7.9% of women were current cigarette smokers and 8.7% were current waterpipe smokers. About 82.4% of all women reported that they are exposed to cigarette smoke and 32.8% reported that they are exposed to waterpipe smoke. The most common place where women are exposed to cigarette and waterpipe smoke was their house (50.4% and 48.7%, respectively) followed by public places (31.4% and 21.4%, respectively). In addition, the husband was the main source for exposure to cigarette and waterpipe smoke (48.5% and 42.7%, respectively). Approximately, 74% of women believed that cigarette smoking is addictive, whereas only 55.1% reported that waterpipe smoking leads to addiction. CONCLUSIONS: Exposure of pregnant women to tobacco smoke is a public health problem in Jordan that requires immediate action.

CO exposure and puff topography are associated with Lebanese waterpipe dependence scale score.

INTRODUCTION: Waterpipe tobacco smoking involves self-administration of the dependence-producing drug nicotine. Few studies have examined if dependence in waterpipe smokers influences toxicant exposure and smoking behavior. METHOD: Current waterpipe tobacco smokers were categorized based on Lebanese Waterpipe Dependence Scale-11 (LWDS-11) score (LWDS-11: LOW < 7; N = 59; HIGH > 13; N = 59). Participants abstained from smoking for 12 hr and then completed a single 30-min waterpipe tobacco smoking episode. Expired-air carbon monoxide (CO) was measured before and 5 min after smoking and puff topography was measured during smoking. RESULTS: Total mean smoking time was 30.9 min (SD = 3.5) and did not differ significantly by LWDS-11 score. CO boost was greater for participants in the HIGH versus LOW groups (62.3 vs. 43.6 ppm, p < .01). Similarly, those in the HIGH versus LOW group took more puffs (198.6 vs. 157.1 puffs, p < .01), longer duration puffs (2.7 vs. 2.3 s, p < .05), puffs with lower flow rate (10.3 vs. 12.6 L/min, p < .01), and less time between puffs (8.0 vs. 12.4 s, p < .001). CONCLUSION: The puff topography of waterpipe tobacco smokers can be predicted by LWDS-11 score, with those scoring higher taking longer duration and lower velocity puffs at a higher frequency. These behavioral differences may underlie the 40% greater CO exposure observed for those with higher LWDS-11 scores. To the extent that waterpipe dependence is associated with more smoke inhalation, more dependent smokers will be exposed to greater amounts of toxic smoke constituents.

Expression of Anaplastic Lymphoma Kinase (ALK) in glioma and possible clinical correlations. A retrospective institutional study.

BACKGROUND: Glioblastoma is considered the most aggressive primary brain tumor. Recurrence after treatment is a significant problem with a failed response to optimal treatment. The recurrence of GBM is linked to different cellular and molecular pathways. Nationwide, in Egypt, astrocytic tumors are the most commonly diagnosed CNS tumor. Anaplastic Lymphoma Kinase (ALK CD246) is an enzymatic protein (RTK) belonging to the insulin receptors superfamily. METHODS: This is a retrospective study including sixty cases of astrocytic tumors (males = 40, mean age = 31.5), (females = 20, mean age = 37.77) obtained through collecting archived paraffin blocks of astrocytic tumor from the Pathology Department, Cairo University Faculty of Medicine during the period from January 2015 till January 2019. All cases were evaluated for ALK expression trying to find any clinical correlations with the clinical data. RESULTS: Correlations were made using a scatterplot matrix correlogram. There was a significant correlation between tumor recurrence and ALK expression (r = 0.8, P < 0.01), and incidence of postoperative seizures (r = 0.8, P < 0.05), and between mean age and score tumor (r = 0.8, P < 0.05). CONCLUSION: Expression of ALK was found to be abundant among high-grade gliomas and tumor recurrence rate was higher in ALK-positive patients. Further studies are needed to evaluate the potential use of ALK as a prognostic marker in cases of GBM.

Neurosurgical intervention in an unusual case of extensive acute disseminated encephalomyelitis - A case report and literature review.

Background: The clinical presentations of demyelinating diseases are variable and can range from mild symptoms to fulminant presentations. Acute disseminated encephalomyelitis is one of those diseases which usually follow an infection or vaccination. Case Description: We report a case of extensive acute demyelinating encephalomyelitis (ADEM) with massive brain swelling. A 45-year-old female presented to the emergency room with status epilepticus. Patient has no history of any associated medical problems. Glasgow coma scale (GCS) was 15/15. CT brain was normal. Lumbar puncture was done and cerebrospinal fluid showed pleocytosis and increased protein content. About 2 days after admission, the conscious level rapidly deteriorated and GCS was 3/15, with the right pupil fully dilated and unreactive to light. Computed tomography and magnetic resonance imaging brain were done. We performed an urgent decompressive craniectomy as a life-saving procedure. Histopathological examination was suggestive of ADEM. Conclusion: Few cases of ADEM with brain swelling were reported, but there is no solid consensus about the appropriate management of these cases. Decompressive hemicraniectomy is a possible choice, but further research is needed to evaluate the proper timing, and indication of surgery.

Spontaneous acute subdural hematoma as a complication of preeclampsia. A case report and literature review.

Background: Acute subdural hematoma (ASDH) is a common form of intracranial bleeding that may be fatal. Trauma is a major cause, while a subset of cases may occur spontaneously. The authors of this article present a case of spontaneous ASDH in the context of preeclampsia and review similar cases in the literature to identify the prognosis. Case Description: A healthy 27-year-old woman presented in her first pregnancy which was complicated with pregnancy-induced hypertension and was sent to a provincial local maternity hospital at 37 weeks of gestation. On day 4 postpartum, the patient complained of severe headache, vomiting and blurred vision. Fundus examination showed papilledema and magnetic resonance imaging showed right acute frontoparietal subdural hematoma. The hematoma was surgically evacuated with decompressive craniotomy. Postoperatively, the patient's symptoms improved. Conclusion: Spontaneous ASDH is a rare event in the context of preeclampsia; however, it should be considered as one of its possible complications. Research should be directed to emphasize on the possibility of spontaneous ASDH as a cause of neurological deterioration in those cases. A proper diagnosis and early intervention for these cases are crucial for both the mother and the fetus.

Tension pneumocephalus as a complication of surgical evacuation of chronic subdural hematoma: case report and literature review.

The management of symptomatic chronic subdural hematoma (CSDH) is surgical evacuation and prognosis in most cases is good. Tension pneumocephalus is the presence of air under pressure in the intracranial cavity. A case of tension pneumocephalus developing as a complication of burr hole evacuation of CSDH is illustrated. In this case, tension pneumocephalus was managed by reopening the wound and saline irrigation with a subdural drain placement. Considering this case report and after a careful review of the literature, the physiopathology, diagnosis, and treatment of this complication are highlighted in the article.

Traumatic Optic Neuropathy: Update on Management.

Traumatic optic neuropathy is one of the causes of visual loss caused by blunt or penetrating head trauma and is classified as both direct and indirect. Clinical history and examination findings usually allow for the diagnosis of traumatic optic neuropathy. There is still controversy surrounding the management of traumatic optic neuropathy; some physicians advocate observation alone, while others recommend steroid therapy, surgery, or both. In this entry, we tried to highlight traumatic optic neuropathy's main pathophysiologic mechanisms with the most available updated treatment. Recent research suggests future therapies that may be helpful in traumatic optic neuropathy cases.
