Primary spinal cord glioblastoma: A rare cause of paraplegia.

Background: Primary spinal glioblastomas are extremely rare neoplasms and account for only 0.2% of glioblastoma cases. Due to the rare incidence of spinal cord glioblastoma in the literature, its natural history/ outcome remains undetermined. The present article describes the clinical presentation, radiological/pathological characteristics, and outcome of the primary spinal cord glioblastoma. Case Description: Two young patients initially presented with paresis that rapidly progressed to paraplegia. Nondermatomal sensory deficits were also noted, mainly affecting the lower limbs. Neuroradiological imaging revealed an extensive intramedullary spinal cord lesion, with no evidence of concurrent intracranial space-occupying lesions. Thoracic laminectomy, followed by tumor debulking and/or biopsy, was performed. The histomorphology was suggestive of glioblastoma, the World Health Organization grade 4 (Isocitrate Dehydrogenase-wild type). They were discharged in stable condition and were started on chemoradiotherapy, with clinicoradiological follow-up. One patient passed away after 9 months of initial presentation. The other patient was alive at 6-month follow-up. Conclusion: Primary spinal glioblastoma is a rare and challenging tumor. Patients commonly present with a progressive paresis, resulting in paraplegia, regardless of the surgical resection extent, and received adjuvant chemotherapy. Therefore, primary spinal cord glioblastoma should be considered in patients reporting a rapid lower limb weakness with neuroradiological evidence of extensive, exophytic intramedullary lesion of the spine. A biopsy-proven histopathological diagnosis is of indisputable importance to establish the final diagnosis and plan treatment options.

Neurological Symptoms and Complications of COVID-19 Among Patients in a Tertiary Hospital in Saudi Arabia.

Objectives In this study, we aimed to determine the frequency of neurological signs, symptoms, and complications in coronavirus disease 2019 (COVID-19) patients. We also sought to explore the general characteristics of stroke patients in particular. Methods A retrospective cohort study was conducted among COVID-19 patients who were hospitalized between April-September 2020 at the Al-Noor Specialist Hospital in Makkah city, Saudi Arabia. The study included patients who were aged ≥18 years and presented with or were reported to have any neurological manifestations and/or complications secondary to COVID-19 infection. Results A total of 79 patients were included. The mean age of the cohort was 63.6 years, with a significant male predominance (67.1%). The most commonly reported neurological signs and symptoms were altered level of consciousness (45.9%), dizziness (11.5%), and focal neurological deficit (10.4%). Acute ischemic stroke was seen in 18 patients. Most of them were males (66.7%). Most strokes were in the right middle cerebral artery territory (MCA) (50.0%). Diabetic patients were four times more at risk to develop stroke [odds ratio (OR)=3.76; 95% confidence interval (CI): 1.1-29.9]. Patients with respiratory failure were 21 times more likely to have a stroke (OR=21.3; 95% CI: 2.2-54.6). Patients with acute respiratory distress syndrome recorded a three-fold increased risk for developing stroke (OR=2.96; 95% CI: 1.25-37.3). Critically ill patients had double the risk of stroke (OR=1.8; 95% CI: 1.1-6.9). Other neurological complications were hemorrhagic stroke (3.3%), subacute/chronic infarction (23.3%), meningitis (10%), and brain mass lesion (3.3%). Conclusions Neurological symptoms and complications are not uncommon among COVID-19 patients. Most of these patients had poor outcomes. Acute ischemic stroke was the most common finding on neuroimaging.

Persistent Parosmia Caused By COVID-19 Infection: An Emerging Symptom.

Objectives Coronavirus disease 2019 (COVID-19) is associated with several known signs and symptoms, including olfactory disturbances leading to anosmia and parosmia. This study aimed to evaluate the clinical features of the emerging symptoms of post-COVID-19 parosmia and to report the outcome of commonly used intervention methods. Methods The study's sample included post-COVID-19 patients who complained of parosmia, presented to otorhinolaryngology clinics at private tertiary care hospitals from December 2020 to April 2021. Patients' data were collected from the hospital system and through direct phone interviews. The Modified Arabic 20-Items Sino-Nasal Outcome Test (MA-SNOT-20) was used to measure the severity of rhinosinusitis symptoms. Results Twenty-one patients were included in the study, and their ages mainly ranged between 20 and 39 years (76.2%), predominantly females 19 (90.5%). Post the COVID-19 illness course, nearly half of the patients (9; 42.9%) reported full recovery of olfaction and taste senses. Nine cases (42.9%) received treatment with intranasal and oral steroids, of which only three cases (14.3%) noticed improvement. The remaining 12 cases (57.1%) did not receive any treatment, two of which improved (9.5%). The maximum MA-SNOT score was 37 while the minimum was 3, and eight patients (38.1%) scores were between one and 10 points. Conclusion Olfactory and taste dysfunctions are common symptoms of COVID-19. The emerging symptom of parosmia is worth reporting in the literature to increase the awareness of this particular symptom in this pandemic era. Many management strategies have been introduced that might be effective. However, further studies are needed to establish evidence-based management protocols.

Subacute Herpes Simplex Type 1 Encephalitis: Case Report With Literature Review.

INTRODUCTION: The typical herpes simplex viral encephalitis (HSVE) course is an acute illness, less commonly it may present as a chronic course, mainly in children, and rarely may it be subacute. Subacute HSVE is rarely described in the literature being reported 4 times only. CASE REPORT: We here report 2 cases of subacute HSV1 encephalitis diagnosed based on cerebrospinal fluid polymerase chain reaction and magnetic resonance imaging findings and review the literature trying to find any specific clinical, laboratory, radiologic diagnostic or prognostic criteria regarding this subacute form of HSVE. CONCLUSION: There is subacute form of HSVE and should be suspected with any subacute febrile illness with nonspecific cognitive impairment even in the absence of focal neurological symptoms and in cases with rapidly progressive dementia. This form has similar radiologic finding and good response to acyclovir but carry even better prognosis than that the acute HSVE.

Clostridium difficile infection in an academic medical center in Saudi Arabia: prevalence and risk factors.

BACKGROUND: Clostridium difficile infection is one of the most common causes of diarrhea in healthcare facilities. More studies are needed to identify patients at high risk of C difficile infection in our community. OBJECTIVES: Estimate the prevalence of C difficile infection among adult patients and evaluate the risk factors associated with infection. DESIGN: Retrospective record review. SETTING: Tertiary academic medical center in Jeddah. PATIENTS AND METHODS: Eligible patients were adults (≥18 years old) with confirmed C difficile diagnosis between January 2013 and May 2018. MAIN OUTCOME MEASURES: Prevalence rate and types of risk factors. SAMPLE SIZE: Of 1886 records, 129 patients had positive lab results and met the inclusion criteria. RESULTS: The prevalence of C difficile infection in our center over five years was 6.8%. The mean (SD) age was 56 (18) years, and infection was more prevalent in men (53.5%) than in women (46.5%). The most common risk factors were use of proton-pump inhibitors (PPI) and broad-spectrum antibiotics. The overlapping exposure of both PPIs and broad-spectrum antibiotics was 56.6%. There was no statistically significant difference between the type of PPI (P=.254) or antibiotic (P=.789) and the onset of C difficile infection. CONCLUSION: The overall C difficile infection prevalence in our population was low compared to Western countries. The majority of the patients who developed C difficile infection were using PPIs and/or antibiotics. No differences were observed in the type of antibiotic or PPI and the onset of C difficile infection development. Appropriate prescribing protocols for PPIs and antibiotics in acute settings are needed. LIMITATIONS: Single center and retrospective design. CONFLICT OF INTEREST: None.

Level of awareness and attitudes toward epilepsy in Qassim, Saudi Arabia: A cross-sectional study.

OBJECTIVES: Reports of poor knowledge about epilepsy in different cities of Saudi Arabia have emphasized the need for a similar study of this issue in the Qassim region. Therefore, we aimed to determine the level of awareness and attitudes toward epilepsy in the population of Qassim, Saudi Arabia. METHOD: A cross-sectional study was conducted in the Qassim region. A valid pretested questionnaire was distributed among Qassim residents in public places, such as malls, mosques, and parks. The sample size consisted of 3800 people from multiple cities in the Qassim region. The study was approved by the Qassim committee in Qassim University, and verbal consent was obtained from participants. RESULTS: Data were obtained from 2253 males (59.3%) and 1544 females (40.6%). A large number of respondents were between 15 and 30 years (59.7%). The data showed that 85.5% of people had heard about epilepsy or read about it and 33% knew a patient with epilepsy while 42.7% had seen or witnessed someone having a seizure. It was also found that 73.2% of parents would allow their child to play with patients with epilepsy, 35.7% would allow their son or daughter to marry a patient with epilepsy, and 74.9% think that patients with epilepsy can be employed in jobs, like other people. CONCLUSION: Insufficient knowledge about epilepsy, which is a very common disorder, has a great and negative impact on people with epilepsy, their families and communities, and the healthcare systems. In our study, we found that good knowledge was associated with being a young adult, male, unmarried, and being a university student.
