Lower Motor Neuron Facial Palsy Following COVID-19 Infection and COVID-19 AZD1222 Vaxzervria (AstraZeneca) Vaccine Administration: Two Case Reports.

Bell's palsy is a lower motor neuron lesion rarely associated with COVID-19 infection or vaccinations. We documented two cases of Bell's palsy in this report, one after contracting COVID-19 infection and the other after administration of AZD1222 Vaxzervria (AstraZeneca) Vaccine. After excluding all possible causes of Bell's palsy in both cases, we determined that COVID-19 infection and the AZD1222 Vaxzervria (AstraZeneca) vaccine were the causes. Thus, we believe COVID-19 and the AZD1222 Vaxzervria (AstraZeneca) vaccine should be considered as causes of Bell's palsy.

Etiological associations of cerebral venous sinus thrombosis among adult sudanese patients: a multicenter cross-sectional study.

Cerebral venous sinus thrombosis (CVST) is a common condition that, if not detected and treated promptly, carries a high risk of morbidity and mortality. CVST's most common aetiological associations are post-partum, pregnancy, and oral contraceptive pills. The purpose of this study was to look into the aetiology of CVST in Sudanese patients in neurological centres in Khartoum state. Methodology: This was a cross-sectional hospital bases study conducted on CVST patients at four neurological centres in Khartoum state in the period from March to October 2020. Patients were studied for the aetiological association of CVST using a standardized questionnaire including medical history, clinical examination, investigation, and treatment. Results: The study included about 60 patients, 50 of whom were female (83.3%) and 10 of whom were male (16.7%). In terms of clinical presentation, almost all patients had headache, followed by visual disturbances in 49 (81.7%), seizures in 46 (76%), disturbed consciousness in 12 (20%), and weakness in 12 (20%). The most common sign was abnormal speech, which was found in eight patients (13.3%), memory disturbances in eight patients (13.3%), evidence of CN VI lesion in three (5%), papilledema in 49 (81.7%), and hemiparesis in 46 (76.7%), while abnormal sensory signs were found in only one patient. The most common aetiological association were pregnancy in 15 (25%), oral contraceptive pills in 11(18.3%), and being in the post-partum period in 23(38.3%). All of the patients' magnetic resonant imaging/magnetic resonant venography results were abnormal. Six patients had extensive sinus involvement, 35 had superior sagittal sinus involvement, and 19 had transverse sinus involvement. After treatment, 45 patients (75%) fully recovered, 11 (18.3%) partially recovered, and 4 (6.7%) died. Conclusion: Post-partum, pregnancy, and oral contraceptive pills were the most common aetiological associations of CVST compared with other populations.

Neurological manifestations of mycetoma: a cross-sectional community-based study.

Mycetoma is a chronic specific granulomatous progressive and disfiguring subcutaneous inflammatory disease. It is caused by true fungi (Eumycetoma) or by higher bacteria (actinomycetoma). Mycetoma mainly affects the lower limbs, followed by the upper limbs, back, and rarely the head and neck. Mycetoma is mainly transmitted through trauma with infected sharp objects. Herein, we want to determine the neurological manifestations of mycetoma in Sudanese patients. Methodology: A descriptive cross-sectional community-based study included 160 patients with mycetoma seen in the White Nile state. A team of doctors collected data using standardized questionnaires that included clinical history, neurological examination, investigations including laboratory, neurophysiological studies, and imaging. Results: Almost 160 patients were included in the study; 90% of them were male. Two patients presented with entrapment neuropathy, one presented with proximal neuropathy, one had peripheral neuropathy, one had dorsal spine involvement and presented with spastic paraplegia with sensory level, one had cervical cord compression, and one patient had repeated attacks of convulsion. Conclusion: Although it is rare, clinicians should highly suspect neurological involvement in mycetoma patients.

Prevalence and risk factors of functional seizures among adult Sudanese patients with epilepsy, a cross-sectional clinic-based study.

Background: Epilepsy can be associated with functional seizures. Our main aim is to assess functional seizures' prevalence and risk factors among adult Sudanese patients with epilepsy. Methods: This cross-sectional clinic-based study was conducted from January to February 2021 at Daoud Charity Clinic in Omdurman city, Sudan. Ninety-nine adult Sudanese patients with epilepsy were included. Data were collected using a validated interview-based semi-structured questionnaire. A senior consultant neurologist and a consultant psychiatrist diagnosed the functional seizures based on full clinical history and investigations. The diagnosis was performed according to International League against epilepsy (ILAE) classification. Results: This study included 99 patients with epilepsy, 57% were females, 79% reside in Khartoum state, and 32% reached secondary school. The main types of epilepsy were generalized tonic-clonic (68%), followed by focal seizures with impaired awareness (11%). The majority of the patients have been diagnosed with epilepsy for over three years (65%). Comorbid epilepsy and functional seizures were found in 29% of the patients, with a significantly higher prevalence in patients with social problems and depression (p = 0.005 and p < 0.01, respectively). Patients with depression had a 14 times higher risk of functional seizures than those without depression, 95% CI [3.8, 52.3]. Conclusion: A remarkably high prevalence of functional seizures was found among adult patients with epilepsy. Patients suffering from social problems and/or depression and poor economic status had a higher tendency to develop functional seizures, especially after two to three years of treatment and above.

AstraZeneca COVID-19 vaccine: A possible risk factor for ischemic stroke and cerebral venous sagittal sinus thrombosis: A case series.

One of the most prevalent neurological impairments is cerebrovascular accident (CVA). Ischemic stroke and CVST have been linked to the AstraZeneca COVID-19 vaccine. Three Sudanese patients developed these diseases after receiving the AstraZeneca COVID-19 vaccine, indicating a relationship between the AstraZeneca COVID-19 vaccine and these conditions.

COVID-19 and cognitive impairment: A cross-sectional clinic-based study.

BACKGROUND: Patients with dementia are more prone to acquire COVID-19 infection. Patients with COVID-19 showed a tendency to develop cognitive impairment. OBJECTIVES: We aimed to study the clinical manifestations of COVID-19 infection among adult Sudanese demented patients and the prevalence of cognitive impairment among adult Sudanese nondemented patients. METHODOLOGY: This is a descriptive cross-sectional study that took place in Sudan, Khartoum state in the period (September to December 2021) in a private neurology/psychiatry clinic. A total of 135 adult Sudanese patients were included in this study and were divided into two groups. The first group consists of 100 patients with a known history of dementia that got infected recently with COVID-19, while the second group consists of 35 patients who developed some sort of cognitive impairment after recovering from COVID-19 infection. Regarding the second group, cognitive functions were assessed by senior consultant neurologist and senior consultant psychiatrist using a well validated neuropsychological measure. RESULTS: Out of 100 patients in the first group, females were 60 and males were 40. Age distribution is between 63 and 98. The common presenting symptoms of COVID-19 among this group were cough and fever (90 patients), diarrhea and vomiting (5 patients), breathlessness (4 patients), coughing of blood (5 patients), convulsions (1 patient), paraplegia (1 patient), and hemiplegia (1 patient). Regarding the second group, age distribution varied from 30 to 80 years. Cognitive functions impairment was noticed as follows: memory recall (22%), memory recognition (23%), memory encoding (24%), processing speed (16%), executive functioning (19%), phonemic fluency (17%), and category fluency (17%). CONCLUSION: Patients with dementia are more susceptible to develop COVID-19 infection. Patients with COVID-19 Infection are at risk of developing some sort of cognitive impairment after recovery.
