The Impact of COVID-19 Vaccine Controversy on Parents' Perceptions of Routine Vaccinations.

Background The COVID-19 pandemic has significantly influenced public perceptions and behaviors related to vaccination. Understanding parental attitudes, knowledge gaps, and vaccination practices post-pandemic is crucial for informing effective public health strategies. This study aimed to investigate parental attitudes, knowledge, and practices toward routine childhood vaccination in the post-COVID-19 era, emphasizing shifts in perspectives and implications for vaccination strategies. Methodology A cross-sectional survey was conducted among 498 parents to assess their attitudes, knowledge, and practices regarding vaccination. Data were analyzed using descriptive statistics, chi-square tests, and t-tests where applicable, with p-values <0.05 considered statistically significant. Results The study revealed diverse parental attitudes toward vaccination post-COVID-19. While a majority (72.9%) maintained positive attitudes toward vaccination schedules and benefits, concerns regarding vaccine safety and efficacy were noted. Knowledge gaps persisted, with 16.5% strongly agreeing that children's vaccinations are weak and have no impact on disease prevention. Despite high adherence to vaccination schedules (68.9%), motivations behind vaccine administration were questioned, as 48.2% strongly disagreed that vaccination was solely for regulatory purposes. Conclusions Post-COVID-19, parental attitudes toward vaccination have evolved, reflecting increased concerns about safety and efficacy. Addressing knowledge gaps, combating misinformation, and enhancing trust in vaccination programs are imperative. Tailored communication strategies, education campaigns, and policy interventions are essential to promote vaccination acceptance and safeguard public health resilience in the post-pandemic era.

Analysis of antibiotic regimens and outcomes in spinal brucellosis: insights from a retrospective cohort study in Makkah, Saudi Arabia.

Background: Brucellosis is a zoonotic disease that is widely spread across the globe, with the number of cases increasing annually. Spinal brucellosis is known to affect about half of patients with brucellosis. Nevertheless, data on the optimal antibiotic regimens for spinal brucellosis are limited. Therefore, this study aims to compare antibiotic treatment regimens for spinal brucellosis at our center in Makkah, Saudi Arabia. Methods: This is a retrospective cohort study of an 11-year period from 2010 to 2021 conducted at a single center in Makkah, Saudi Arabia. All patients with spinal brucellosis were included. Patients were excluded if the duration of the received antibiotic regimen or follow-up was poorly documented. Data analysis was conducted using RStudio (R version 4.1.1). Categorical variables of each regimen used by the patients were presented as frequencies and percentages, while numerical variables were summarized using the median and interquartile range (IQR). Results: A total of 35 patients were included; the median (IQR) age of the patients was 58.0 (48.0 to 63.0) years. The most frequently reported symptoms upon admission included low back pain (83.3%). The most frequently administered regimen was the combination of streptomycin + doxycycline + rifampicin (SDR) (20 patients, 55.6%), followed by the combination of streptomycin + rifampicin + trimethoprim/sulfamethoxazole (SRT) (eight patients, 22.2%). Overall, out of the total 35 patients who received first-line treatment, only six patients experienced therapy failure. Out of the total six patients who experienced first-line treatment failure with SDR (five patients, 83%) and SDT (one patient, 17%), surgery was indicated for three patients. Surgical intervention was deemed necessary in 12 patients (34%). Three patients chose not to undergo surgical intervention but still showed complete improvement upon completing the treatment duration. One patient experienced a postoperative complication, resulting in paraplegia. Conclusions: In this study, we found that among 35 patients, treatment failure was observed only in six patients who received triple therapy. In addition, surgical intervention was indicated in 12 patients; however, three patients refused surgery and improved ultimately after changing or extending the duration of the antibiotic regimen.

Exploring plant-derived small molecules as inhibitors of Marburg virus RNA binding protein activity.

The search for antiviral medications is greatly influenced by the hunt for potent inhibitors of viral proteins. To find possible inhibitors of the RNA binding activity of the Marburg virus VP35 protein, we used a thorough in silico drug discovery approach in this investigation. A comprehensive virtual screening process, followed by a detailed MMGBSA analysis, led to the discovery of four potential inhibitory compounds viz. Kudzuisoflavone A, Miquelianin, Rutin, and Protopseudohypericin. They were identified from an extensive library of phytomolecules derived from three medicinal plants: Adiantum capillus-veneris, Hypericum perforatum, and Pueraria montana. In molecular dynamics (MD) simulations, all these compounds showed steady binding to the target protein and favourable interactions. Notably, the free binding energies of all the selected compounds were better than the myricetin, a well-known blocker of the VP35 protein of the Ebola virus. Overall, this investigation offers insightful information about the molecular interactions and binding dynamics of the identified inhibitors' binding to the VP35 protein of the Marburg virus. The findings highlight the potential of three particular medicinal plants as sources of key chemicals for the creation of brand-new Marburg virus antiviral drugs. More experimental validation and optimization of the identified inhibitors are necessary in order to transform these findings into effective medicines for treating Marburg virus infections.Communicated by Ramaswamy H.

Schistosomiasis Involving the Central Nervous System: Case Report of a Rare Complication.

Introduction: Schistosomiasis is a parasitic infection caused by schistosome invasion of blood circulation. Neuroschistosomiasis is a severe cerebral complication that accounts for less than 2.3% of reported cases. Patients present with progressive encephalitis, seizures, or both. Management includes antiparasitic medications, steroids, and surgical intervention. Case Presentation. We report a case of a 44-year-old female who presented to the ER with a history of transient loss of consciousness (LOC) and seizure. Radiological investigations revealed a right frontal brain lesion. Histopathological results confirmed the diagnosis of schistosomiasis. Conclusion: Schistosomiasis is a parasitic infection commonly diagnosed in patients who live in tropical areas. Early diagnosis with radiological and histopathological evaluation is required to identify patients at risk of developing severe neurological complications.

Facially Driven Digital Workflow for Maxillary and Mandibular Milled Implant- Retained Overdentures Using Two Different Unsplinted Attachment Systems: Case Report.

Unsplinted attachment systems for implant overdentures offer various benefits for edentulous patients, including cost-effectiveness, enhanced cleansability, and less need for manual dexterity. This article describes a facially driven digital workflow for fabricating a maxillary implant overdenture retained by conometric-style attachments (Atlantis® Conus) with a palateless design opposing an implant overdenture retained by standard attachments (LOCATOR®). This procedure provides a predictable and accurate technique to digitally scan the master casts with wax rims for articulation and to guide the digital teeth design set-up for a predictable esthetic outcome. The removable prosthesis workflow involves virtual teeth set-up, a 3D-printed trial denture, a milled definitive prosthesis, and intraoral pick-up for both unsplinted attachment systems. The clinical and laboratory steps are described.

The Use of Pain Severity and Its Impact as a Predictor for MRI Findings: A Cross-Sectional Study in Ta'if, Saudi Arabia.

Background Low back pain (LBP) is common and considerably impacts daily lives across all age groups. MRI is not frequently used as a first-line investigation for patients presenting with LBP, except in the presence of red-flag symptoms. This study aimed to use pain severity and its impact as a predictor for MRI findings to help physicians decide whether a patient needs an MRI. Methods This cross-sectional study was conducted at the outpatient clinic of the neurosurgery department. The questionnaire included demographic data of the patients, red-flag symptoms, and the Dallas Pain Questionnaire (DPQ). The primary physician then determines whether the patient should have an MRI appointment. Results The study included 100 patients with LBP, of which 71 had chronic LBP (CLBP). Out of these 71, an MRI was requested for 62, but only 26 had findings related to LBP. Regarding the impact of CLBP on daily activities as measured by the DPQ, there was a significant association between those whose CLBP affected their daily activities and the decision to request an MRI. However, no significant statistical association was found between the three other parameters of the DPQ and the primary physician's decision to request an MRI. Conclusion Concerning the use of the DPQ questionnaire to predict MRI findings in patients with CLBP, the study indicates that significant pain impact on the DPQ does not necessarily correlate with MRI findings related to LBP. This suggests that the DPQ evaluation tool has no advantage over a physician's clinical judgment.

Patient Satisfaction in Dental Healthcare Settings at Saudi Ministry of Health: A Descriptive Study.

Background: Patient satisfaction is crucial for assessing healthcare quality and identifying strengths and weaknesses in healthcare organizations. In Saudi Arabia, the Ministry of Health (MOH) implemented the Patient Experience Measurement Program to enhance patient experience and healthcare quality. This study aimed to identify specific aspects of patient satisfaction with dental visits in Saudi Arabia to improve dental care quality and inform dental services development. Methods: The study used a standardized self-administered questionnaire (Health Links/Press Ganey) and analyzed surveys from patients who visited MOH-specialized dental clinics in Saudi Arabia during the first half of 2022. The dental section comprised 20 questions across five domains, with patients rating their experience on a 5-point Likert scale. Statistical analysis was performed using IBM SPSS Statistics 25. Results: A total of 964 patients were surveyed. The overall patient satisfaction with dental settings was 3.61 out of 5.0 (72.2%). The highest satisfaction score was for personal issues with the dental clinic domain (3.93/5; 78.6%), while the least satisfaction score was for access to the dental clinic domain (3.29/5; 65.8%). Among all items, the cleanliness of the facility showed the highest satisfaction score (4.11/5; 82.2%). The least satisfaction was for the ease of contacting the dental clinic (2.71/5; 54.2%). Conclusion: The study found high levels of satisfaction among Saudi patients with dental services provided through MOH facilities across various component domains. This highlights the crucial role of dentists in ensuring high-quality dental care and serves as an indication of the overall healthcare quality in MOH facilities.

Awareness of Carpal Tunnel Syndrome Among Adults in the Western Region of Saudi Arabia: A Cross-Sectional Study.

Introduction Carpal tunnel syndrome (CTS) is a peripheral neuropathy that happens when the median nerve is compressed by the transverse carpal ligament within the carpal tunnel. Public awareness is crucial for early detection and intervention; therefore, this study aims to assess the awareness of CTS among the adult population in the western region of Saudi Arabia. Methods The study design was a cross-sectional study where 1400 participants (although 1199 answers were included) from the western region were randomly asked to fill in an online questionnaire that was delivered to them via social media applications. Results The study sample was predominantly females (57.1%), and 88.7% were Saudi, mostly students and professionals (53% and 25.2% respectively); predominant chronic illness among study participants was diabetes mellitus (7%), and only 2% of the sample (27 participants) were diagnosed with CTS. Participants showed more level of awareness regarding the causes and features of CTS, 630 participants (52.5%) had a good awareness of the causes, and 652 (54.4%) had a good awareness of the features. Meanwhile, participants showed a poorer level of awareness regarding treatment, effects, and prevention; percentages of poor awareness were 56% (672) for treatment, 51.9% (622) for effects, and 52.8% (633) for prevention. Conclusion The study shows that the adult population in the western region of Saudi Arabia had insufficient awareness of CTS, especially regarding treatment, effects, and prevention. Therefore, more campaigns should be made to enhance population awareness of CTS, and the study also suggests a link between CTS and chronic diseases.

An Evaluation of the Effect of Social Media Platforms on the General Population's Decision-Making About Cosmetic Procedures in Makkah City, Saudi Arabia.

Background and objective Aesthetic procedures are one of the most commonly performed medical procedures. Surgical and non-surgical cosmetic treatments that are routinely performed include breast augmentations, rhinoplasty, botulinum toxin, and fillers. Several factors contribute to the increase in the popularity of these procedures, including body image dissatisfaction, the opinion of peers, and surgeon-related factors such as the surgeon's reputation, board certification, or years of experience. In addition, recent evidence suggests that active and passive usage of highly visual social media that focus on appearance-centric content have been positively associated with the acceptance of, and desire for, cosmetic procedures. In this study, we aimed to investigate the influence of social media on individuals' decision-making in terms of cosmetic procedures. Method The setting for this population-based cross-sectional study was public places in Makkah City, Saudi Arabia, and it was conducted from September to November 2021. Our study included adults above the age of 18 years. The exclusion criteria were as follows: non-Arabic speakers and individuals with congenital anomalies or dysmorphic dermatological diseases. The final sample consisted of 364 participants. All analyses were carried out using IBM SPSS Statistics version 28 (IBM Corp., Armonk, NY). Continuous and categorical variables were compared using ANOVA and Pearson's Chi-squared test. Result A total of 364 participants were included in the study, and 80% of them used their phones on a daily basis for >4 hours per week. The mean age of the participants was 27.4 ± 8.3 years, and they had a mean BMI of 25.0 ± 6.4 kg/m2; 60% of the participants were female. Participants with a history of cosmetic procedures or a desire to undergo cosmetic procedures reported a similar pattern of daily phone use. There was no significant association between the reported history of cosmetic procedures and the daily duration of selected social media platform use. Conclusion We found no significant correlation between the hours spent on social media and the participants' history or desire for cosmetic procedures. Only 54 subjects compared themselves to social media celebrities. These findings could be attributed to the fact that the Makkah population is conservative in their religious attitudes and traditions, which makes them less susceptible to social media influences.

Dermatological Lesions of Cholesterol Embolisation Syndrome and Kaposi Sarcoma Mimic Primary Systemic Vasculitis: Case report study.

Primary systemic vasculitis can present with a wide spectrum of manifestations ranging from systemic non-specific features such as fever, malaise, arthralgia and myalgia to specific organ damage. We describe two cases of cholesterol embolisation syndrome and Kaposi sarcoma mimicking primary systemic vasculitis, both of which were characterised by features such as livedo reticularis, blue toe syndrome, a brown purpuric skin rash and positive perinuclear anti-neutrophil cytoplasmic antibodies associated with Kaposi sarcoma. Establishing the right diagnosis was challenging and thus this report aimed to highlight the possible ways to distinguish them from primary systemic vasculitis.

Prevalence of Dental Anomalies and Its Role in Sex Estimation among Children of Jazan Region, Saudi Arabia.

BACKGROUND: This study aimed to ascertain the prevalence of dental anomalies and their ability to estimate sex status. MATERIAL AND METHODS: This cross-sectional radiographic study was based on the evaluation of dental anomalies of Saudi children aged between 5 and 17 years. A total of 1940 orthopantomograms (OPG) were screened, of which 1442 were included. All the OPGs were digitally evaluated with ImageJ software. The demographic variables and dental anomaly findings were subjected to descriptive and comparative statistical analysis. Discriminant function analysis was conducted for sex estimation. p value < 0.05 was considered as significant. RESULTS: The mean age of the children in this study was 11.35 ± 0.28 years. At least one dental anomaly was detected in 161 children (11.17%), including 71 males and 90 females. Only 13 children (8.07%) presented with more than one anomaly. The most common dental anomaly detected was root dilaceration (47.83%) followed by hypodontia (31.68%). The least common dental anomaly was infraocclusion (1.86%). The sex prediction accuracy using discriminant function analysis was 62.9% (p < 0.01). CONCLUSION: The prevalence of dental anomalies was 11.17% with root dilaceration and hypodontia being the most common. The role of dental anomalies in sex estimation was found to be ineffective.

Digital Smile Design and Fabrication of CAD/CAM Restorations in a Complex Esthetic Case.

Analog design protocols through the use of wax-ups are highly variable, technique sensitive, and operator dependent. Current digital smile design and treatment planning tools facilitate simplified processes based on the patient's face as well as specific esthetic and functional needs of the individual patient. The initial smile design achieved with an advanced and novel smile design software enables a straightforward treatment plan and execution, even in complex esthetic situations where various restorations are needed. This case report describes the clinical and laboratory steps to address the esthetic and functional requirements of a patient with complex restorative needs using a complete digital workflow.

Rhino-Orbital-Cerebral Mucormycosis: A Rare Complication of Uncontrolled Diabetes.

Introduction: Fungal infection of the central nervous system has become more common over the past two decades. It is frequently diagnosed in patients with underlying pathological conditions. We herein report a case of rhino-orbital-cerebral mucormycosis by outlining the clinical presentation, radiological images, histopathological findings, management plan, and its clinical outcome. Case Description. A 47-year-old man, known to have type 2 diabetes mellitus, presented with severe headache involving the left side of the face, numbness along the left V2 trigeminal nerve, ptosis and dryness of the left eye, short-term memory loss, and right hand numbness. He had a social history of being a bee farmer for which he was exposed to bee stings several times in the past. Neuroradiological imaging showed a left temporal ring-enhancing lesion, suggestive of abscess. The patient underwent craniotomy and resection of the lesion. The histopathological evaluation was suggestive of cerebral mucormycosis, fungal sinusitis, and invasive skull base mucormycosis. Conclusion: Rhino-orbital-cerebral mucormycosis is a fulminant fungal infection commonly diagnosed in patients with uncontrolled diabetes. Early diagnosis with radiological and histopathological evaluation is required to identify patients at risk of rhino-orbital-cerebral mucormycosis.

Structural Changes in Primary Teeth of Diabetic Children: Composition and Ultrastructure Analysis.

Diabetes affects the developing enamel by altering the mineralization process, which can have a detrimental effect on oral health. The objectives of this study were to examine the ultrastructure and composition of surface enamel in primary teeth of diabetic children and its clinical implications. Hundred extracted primary teeth from diabetic children (Test group: n = 50) and healthy children (Control group: n = 50), between 6 and 12 years of age, were subjected to scanning electron microscopy to qualitatively examine the enamel surface. Energy dispersive X-ray (EDX) analysis was performed to investigate the mass percentage of calcium (Ca) and phosphorous (P) in the surface enamel. Ultrastructural aberrations of surface enamel were observed in the test group teeth. Additionally, prism perforations were seen at the junction of rod and inter-rod enamel and the prisms were loosely packed. An even aprismatic layer of surface enamel was evident in the control group teeth. There was a statistically significant difference (p < 0.05) of Ca and P mass percentage between the test and control group teeth. The mean mass percentage rates of Ca and P were 33.75% and 16.76%, respectively. A poor surface characteristic and elemental composition of the enamel surface of primary teeth is observed in diabetic children. Therefore, appropriate caries preventive measures are mandatory to maintain the structural integrity of the tooth in these patients.

Effect of Application of Repeated Downhill Walking Bouts on Ankle Isokinetic Parameters in Children with Obesity.

BACKGROUND: Obesity among children became of high concern. Obesity can affect many health aspects including muscular strength. Downhill walking is a useful intervention to enhance muscular strength, especially in older adults. OBJECTIVE: The current study's purpose was to investigate the effect of repeated bouts of downhill walking on ankle isokinetic parameters in children with obesity. METHODS: 32 obese male children aged from 8 to 12 years engaged in the study. The children were divided into two groups: the level walking group (LWG) (n = 16) and the downhill walking group (DWG) (n = 16). Participants in both groups walked 20 minutes on the treadmill, two sessions per week for 6 weeks, with a speed of 5 km/h, and the treadmill slope used for the DWG was set at -20%. Isokinetic dynamometry (Cybex 6000) was used to analyze the normalized eccentric and concentric torque of both ankle dorsiflexors and plantar flexors of the dominant leg in all participants. RESULTS: The normalized peak torques for eccentric plantar flexion, concentric plantar flexion, eccentric dorsiflexion, and concentric dorsiflexion significantly increased by 38.66%, 23.87%, 38.58%, and 15.51%, respectively, after repeated bouts of downhill walking. Level walking resulted in nonsignificant improvement in the muscular torques. CONCLUSION: Downhill walking is a beneficial intervention in improving ankle muscular torques of obese children.

The Role of the Lateral Pterygoid Muscle in Articular Disc Displacement: A Cross-sectional Magnetic Resonance Imaging Study.

OBJECTIVE: The objective of the study is to determine the role of Lateral Pterygoid Muscle LPM in the articular disc displacement ADD, which is considered controversial due to the variations in the pattern of insertion of the Superior Lateral Pterygoid Muscle SPLM. BACKGROUND: It is well understood that the superior head of the lateral pterygoid muscle has only a single insertion pattern among individuals, in which the muscle is attached to the articular disc and capsule. However, recent findings in many studies have shown a noticeable variation in the insertion pattern of the upper LPM. METHODS: MRI examinations were collected at King Faisal Specialist Hospital & Research Centre, Riyadh, Saudi Arabia. Scans of 61 patients (41 females, 20 males; mean age 33 years old) with symptoms of temporomandibular dysfunction were reviewed retrospectively. The direction of their articular disc displacement was evaluated through sagittal and coronal views in both open and closed mouth positions. RESULTS: There was no statistical significance found between the LPM attachment types and TMJ disc position. The chi-square test also showed no significant difference between the type of LPM attachment and the condylar location. Forty-five percent of the articular discs were located between the articular eminence and the glenoid fossa. The majority of the disc displacement was in the anterior direction. CONCLUSION: There was no statistically significant association found between the type of LPM attachments and the direction of disc displacement.

Molecular determinants of etoposide resistance in HL60 cells.

Chemotherapy resistance is the main reason for treatment failure in acute myeloid leukemia (AML) and the major cause of its mortality. Etoposide is a DNA topoisomerase-II inhibitor that is used either as a single agent or in combination with cytarabine, azacytidine, vinca alkaloids, and anthracyclines for the treatment of relapsed /refractory AML. In this study, we sought to determine and understand the mechanism of etoposide resistance in AML using the HL60 cell line.HL60 cells were treated with incremental doses of etoposide and resistant colonies were isolated by culturing the resistant cells in semi-solid culture media. Three clones were selected for etoposide resistance namely, HL60-EtopR H1A, HL60-EtopR H1B, and HL60-EtopR H1C which demonstrated 4.78, 2.39, and 4.42-fold higher resistance to etoposide compared with the parental cells. To determine molecular differences between the etoposide-resistant HL60-EtopR cells and the parental cells, microarray-based gene expression profiling was performed. We found up regulation of members of the src tyrosine kinase family genes in the etoposide resistant cells. Further studies are required to evaluate the role of Src inhibitors in targeting etoposide resistant cells.

Study of Lateral Wall Thickness of the Maxillary Sinus in Left and Right Sides for Female and Male: A Cross Sectional Retrospective Study Using Cone Beam Computed Tomography.

BACKGROUND: Dental implants are considered the first option to replace missing teeth. Alveolar bone resorption gradually progresses following tooth extraction leading to loss of vertical bone dimension for implant placement. The lateral window approach is the most commonly used procedure to treat vertical bone loss. OBJECTIVE: The aim of the present study is to evaluate the Lateral Wall Thickness (LWT) of the maxillary sinus and determine the influence of gender and side on maxillary LWT. METHODS: This study involved a cross sectional retrospective study. Cone- beam computed tomography data were collected from 99 patients with a total of 198 maxillary sinuses that met the inclusion criteria. The patient age ranged between 18 to 35 years. On the selected sagittal section, the points of measurement are determined by a perpendicular line at 5 mm from the lowest point of the sinus floor. Measurements were taken at four different areas; first premolar (P1), second premolar (P2), first molar (M1), and second molar (M2). Descriptive statistics were used to calculate mean lateral wall thickness for each tooth, and student's t-test was used to test the effect of gender and side on maxillary LWT. RESULTS: The greatest mean LWT was observed around the left first maxillary molar (2.43±0.82), while the lowest mean LWT was observed around the right second maxillary premolar (1.62±0.61). There was no significant difference in the LWT around any tooth (M1 p=0.56, M2 p=0.92, P1 p=0.14, P2 p=0.19). CONCLUSION: There was no significant difference in both males and females of the lateral wall thickness in the left and right side of maxillary sinus.

Idiopathic thoracolumbar spinal epidural arachnoid cysts: A case report and systematic review.

Background: Idiopathic spinal epidural arachnoid cysts (SEACs) are rare and may cause myelopathy and cord compression. They typically arise from a congenital defect in the dura that communicates with the intrathecal subarachnoid space. Although the ideal treatment of SEACs is direct dural repair and cyst excision, there is as yet no clear standard of care for the management of these lesions. Methods: A 47-year-old female presented with myelopathy attributed to an magnetic resonance imaging-documented posterior epidural T12-L2 cyst (i.e., 1.1 × 6 × 3.3 cm) lesion. The patient underwent a direct dural repair of the fistulous communication between the subarachnoid space and the cyst, along with cyst drainage/ excision through a right-sided laminotomy. Postoperatively, the patient was asymptomatic. We additionally reviewed the literature regarding the management of SEACs. Results: Our review yielded 14 articles involving 18 patients with predominantly thoracolumbar (57%) SEACs that were either communicating (61%) or not communicating (39%) with the subarachnoid space. They averaged 35.5 years of age and exhibited a male preponderance (66%). Symptoms typically included pain (78%), followed by weakness/myelopathy (42%). Surgery frequently included bilateral laminectomies (57%) followed by unilateral laminectomies (50%) that typically resulted in symptom resolution. Conclusion: SEACs are rare typically thoracolumbar lesions that may cause myelopathy which resolves following direct dural closure/subarachnoid fistulous occlusion.

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.
