Computer vision syndrome among Saudi population: An evaluation of prevalence and risk factors.

INTRODUCTION: In the recent era of technological evolution, electronic devices have become an essential part of our lives, not merely in professional work settings, but also in daily leisure activities. Although these devices have simplified our lives, they are associated with a wide variety of health complaints. Thus, the so-called computer vision syndrome (CVS) has become a growing public health problem and has gained significant attention as it plays an important role in the quality of life of each individual, which in turn has put an increased burden on the health care system. Eye symptoms are among the most reported, yet extraocular symptoms were frequently described as adding an extra load. METHOD: An electronic survey was distributed randomly through social media platforms among the general population in Saudi Arabia, between the period from July to December 2017, irrespective of their sociodemographic factors, aiming to determine the prevalence of CVS and to verify the most common associated risk factors. RESULTS: In total, 690 participants were involved in our study, with a mean age of 33.8 years. Of these, 77.6% suffer from CVS, with eye-burning being the most common ocular symptoms (71%), as well as itching (67.5%), blurred vision (65%), tearing (62.3%), and other eye symptoms being reported. Neck/shoulder pain was found to be the most prevalent extra ocular symptom (85.2%); also back pain and headache are frequently expressed (78% and 70% respectively). A significant positive correlation was observed between CVS symptoms and time spent using the devices (P-value: 0.002). CONCLUSION: As technology advances, electronic devices have become a common tool that is used for different purposes on daily basis. We found in our study that the so-called computer vision syndrome is a growing public health problem. Thus, community education about the impact of such a lifestyle for proper handling of electronic devices must be addressed to avoid such health complaints.

The utility of decompressive craniectomy in severe traumatic brain injury in Saudi Arabia trauma centers.

Background: Decompressive craniectomy (DC) represents an effective method for intracranial pressure (ICP) reduction in cases of severe traumatic brain injury (TBI). However, little is known regarding the attitude of practicing neurosurgeons toward decompressive craniectomy (DC) in Saudi Arabia.Objective: We aimed to explore the perspective on DC among neurosurgeons in Saudi Arabia.Methods: An electronic survey was distributed via e-mail to members of the Saudi Association of Neurological Surgery (SANS).Results: A total of 52 neurosurgeons participated in this survey. The majority of these neurosurgeons practice in a governmental (95.2%), tertiary hospital (75.5%) with academic affiliations (77.6%). Most surgeons (71.4%) agreed that the DC approach for managing refractory ICP is supported by evidence-based medicine. The majority of the participants choose to perform DC on a unilateral basis (80%). Interestingly, DC followed by duraplasty was performed by only 71% of these surgeons, with 29% of the respondents not performing expansive duraplasty.Conclusion: In Saudi Arabia, the utility of DC in cases of TBI with refractory intracranial hypertension has not been clearly defined among practicing neurosurgeons. The development of appropriate, widely adopted TBI guidelines should thus be a priority in Saudi Arabia to reduce variability among TBI care practices. In addition, a national TBI registry should be established for documenting different practices and longitudinal outcomes.

Posterior fossa extra-axial variations of medulloblastoma: a pictorial review as a primer for radiologists.

Manifestations of an atypical variant of medulloblastoma of the posterior fossa in extra-axial locations have been reported, and key questions concerning its interpretation have been raised previously. This review illustrated the clinico-radiological and histopathological features of the posterior fossa extra-axial medulloblastoma and described possible management strategies. We thoroughly reviewed all atypical anatomical locations of medulloblastoma reported within the posterior fossa and extra-axial spaces. The main characteristics of diagnostic imaging and histopathological results, primarily the distinctive radiopathological characteristics, were summarized to distinguish between intra- and extra-axial medulloblastoma, or pathologies mimicking this tumor. Most cases of posterior fossa extra-axial medulloblastoma have been reported in the cerebellopontine angle, followed by the tentorial and lateral cerebellar locations. The dural tail sign, which is commonly observed in meningioma, is rarely seen in intra- or extra-axial medulloblastoma and might be associated with other benign or malignant lesions. In addition to magnetic resonance imaging, the proposed new imaging techniques, including advances in modern neuroimaging modalities, were discussed, as potentially efficient modalities for characterizing extra-axial medulloblastoma. Radionuclide imaging and magnetic resonance perfusion imaging are practical alternatives to limit the number of differential diagnoses. We believe that medulloblastoma cases are likely under-reported because of publication bias and frequent tumors in unusual locations. Addressing these issues would help establish a more accurate understanding of this entity.

The longitudinal impact of COVID-19 pandemic on neurosurgical practice.

OBJECTIVE: This observational cross-sectional multicenter study aimed to evaluate the longitudinal impact of the coronavirus disease 2019 (COVID-19) pandemic on neurosurgical practice. METHODS: We included 29 participating neurosurgeons in centers from all geographical regions in the Kingdom of Saudi Arabia. The study period, which was between March 5, 2020 and May 20, 2020, was divided into three equal periods to determine the longitudinal effect of COVID-19 measures on neurosurgical practice over time. RESULTS: During the 11-week study period, 474 neurosurgical interventions were performed. The median number of neurosurgical procedures per day was 5.5 (interquartile range [IQR]: 3.5-8). The number of cases declined from 72 in the first week and plateaued at the 30's range in subsequent weeks. The most and least number of performed procedures were oncology (129 [27.2 %]) and functional procedures (6 [1.3 %]), respectively. Emergency (Priority 1) cases were more frequent than non-urgent (Priority 4) cases (178 [37.6 %] vs. 74 [15.6 %], respectively). In our series, there were three positive COVID-19 cases. There was a significant among-period difference in the length of hospital stay, which dropped from a median stay of 7 days (IQR: 4-18) to 6 (IQR: 3-13) to 5 days (IQR: 2-8). There was no significant among-period difference with respect to institution type, complications, or mortality. CONCLUSION: Our study demonstrated that the COVID-19 pandemic decreased the number of procedures performed in neurosurgery practice. The load of emergency neurosurgery procedures did not change throughout the three periods, which reflects the need to designate ample resources to cover emergencies. Notably, with strict screening for COVID -19 infections, neurosurgical procedures could be safely performed during the early pandemic phase. We recommend to restart performing neurosurgical procedures once the pandemic gets stabilized to avoid possible post pandemic health-care system intolerable overload.

Neurosurgical Procedures and Safety During the COVID-19 Pandemic: A Case-Control Multicenter Study.

OBJECTIVE: Quantitative documentation of the effects of outbreaks, including the coronavirus disease 2019 (COVID-19) pandemic, is limited in neurosurgery. Our study aimed to evaluate the effects of the COVID-19 pandemic on neurosurgical practice and to determine whether surgical procedures are associated with increased morbidity and mortality. METHODS: A multicenter case-control study was conducted, involving patients who underwent neurosurgical intervention in the Kingdom of Saudi Arabia during 2 periods: pre-COVID-19 and during the COVID-19 pandemic. The surgical intervention data evaluated included diagnostic category, case priority, complications, length of hospital stay, and 30-day mortality. RESULTS: A total of 850 procedures were included, 36% during COVID-19. The median number of procedures per day was significantly lower during the COVID-19 period (5.5 cases) than during the pre-COVID-19 period (12 cases; P < 0.0001). Complications, length of hospital stay, and 30-day mortality did not differ during the pandemic. In a multivariate analysis comparing both periods, case priority levels 1 (immediate) (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.24-2.67), 1 (1-24 h) (OR, 1.63; 95% CI, 1.10-2.41), and 4 (OR, 0.28; 95% CI, 0.19-0.42) showed significant differences. CONCLUSIONS: During the early phase of the COVID-19 pandemic, the overall number of neurosurgical procedures declined, but the load of emergency procedures remained the same, thus highlighting the need to allocate sufficient resources for emergencies. More importantly, performing neurosurgical procedures during the pandemic in regions with limited effects of the outbreak on the health care system was safe. Our findings may aid in developing guidelines for acute and long-term care during pandemics in surgical subspecialties.

"Cable Suturing Technique" a Dural Obliteration Method for the Prevention of Cerebellar Herniation through a Large Occipital Meningocele.

The authors present a patient who had a large occipital meningocele, which was transformed into an encephalocele after primary closure due to a large skull defect. Thus, the technical importance of classifying patients with occipital meningocele with a large skull defect and a tight dural obliteration is crucial, not to leave a wide dead space with a potential risk of cerebellar herniation. Encephalocele and meningocele are embryological anomalies, which result in intracranial structures herniation due to inborn skull defect. Acquired encephalocele may develop through the same defect with normal cerebellar tissues; since the prognosis of occipital encephalocele may worsen as the size of herniation increases, the patient underwent a modified dural obliteration technique (Cable Suturing Technique) to adjust the size of the dura and to strengthen it to prevent the risk of future herniation followed by cranioplasty and the cerebellar herniation regressed significantly after the procedure.

Total Spondylectomy for Upper Thoracic Spine Giant Cell Tumor: A Case Report.

INTRODUCTION: Giant cell tumors (GCT) are benign lesions that are generally locally aggressive tumors with occasional malignant behavior. These tumors are most frequently encountered in long bones; however, they also occur rarely in the spine. GCT of the spine are rare pathological entities, and spinal involvement shows a sacral predilection, with only a few cases involving the supra-sacral segment (mobile spine). Only a few cases of thoracic spinal GCT are reported in the literature; these tumors are particularly uncommon in the thoracic segment. PRESENTATION OF CASE: A 29-year-old man presented with a complaint of neck pain over the previous six months that radiated to his left hand. GCT of the upper thoracic spine was diagnosed, which was surgically managed using a 2-stage approach involving total resection of the tumor followed by spondylectomy and multilevel spinal fixation. DISCUSSION: Accurate diagnosis of vertebral column lesions, and choosing an optimum management plan are crucial. In the majority of cases, En-bloc resection of GCTs is not feasible ought to the close contact of the lesion with the spinal cord. Larger studies are encouraged to ascertain the efficacy of variable management approaches, particularly compared with piecemeal resection techniques. CONCLUSION: Spinal GCT are a unique group of tumors with an uncommon and unexpected presentation. Although surgery is the mainstay of treatment for spinal GCT, the management of this tumor can be challenging. No clear management algorithm has been established, and the tumor displays an unpredictable course. Therefore, each case needs tailored treatment.

Endoscopic transnasal resection of optic pathway pilocytic astrocytoma.

PURPOSE: Optic pathway gliomas (OPGs) are low-grade neoplasms that primarily affect children. The management of OPGs remains controversial. Reports on the use of the endoscopic endonasal approach (EEA) in OPGs are extremely limited, and no such reports exist on its utility for pediatric OPGs. Here, we report our results and experience with OPGs treated with the EEA. METHODS: We retrospectively reviewed the medical records of OPG patients who were treated surgically via the EEA at our institutions from 2015 to 2017. Data on the demographics, clinical presentation, surgical complications, clinical outcomes, radiological imaging, and visual outcomes were recorded for each patient. RESULTS: Four cases were identified, with visual disturbances being the predominant complaint. The mean patient age was 15.5 years. Three cases showed normal preoperative hormonal profiles, but one patient had hypothyroidism. All tumors identified in this study were World Health Organization grade I pilocytic astrocytomas. Surgical complications included hypopituitarism in two patients, meningitis in two patients, cerebrospinal fluid leak in one patient, and transient diabetes insipidus in one patient. No patient experienced worsening neurological or visual symptoms postoperatively. CONCLUSIONS: Although our data are preliminary, the EEA provides a direct corridor to OPG with acceptable results in terms of tumor resection and visual outcomes. Hypothalamic-pituitary axis dysfunction remains a limitation of any treatment modality for OPGs and should be considered whenever possible. Definitive conclusions are pending as the learning curve of this approach is steep. Further work is needed to understand patient selection for such an approach.
