Comorbid conditions in Egyptian patients with migraine.

BACKGROUND: Identifying migraine comorbidities may guide prognosis and treatment options. This study aimed to assess the frequency of comorbid conditions among adults with migraine living in Greater Cairo. METHODS: In this cross-sectional study, Egyptian migraine sufferers aged ≥ 18 years living in Greater Cairo were consecutively recruited (April 2019 - April 2021). Following The International Classification of Headache Disorders-third edition, diagnosis of migraine was confirmed, and the type of migraine was defined as whether episodic or chronic, with or without aura, with childhood/adolescence or adulthood onset. Specialist physicians from the research team assessed comorbid conditions among the respondents. RESULTS: The mean age of respondents (n = 1064) was 35 ± 7. Irritable bowel syndrome represented the most common comorbidity in our patients (45.5%), followed by vitamin D deficiency (41.8%). The frequency of epilepsy, stroke, multiple sclerosis, and systemic lupus erythematosus was significantly higher in patients with chronic than episodic type (χ2 = 4.514, P = 0.034), (χ2 = 12.302, P = 0.001), (χ2 = 12.302, P = 0.001), (χ2 = 4.806, P 0.028), respectively. Females with menstrual migraines had a significantly higher frequency of generalized anxiety disorder, panic attacks, and restless leg syndrome than those with non-menstrual migraines (χ2 = 7.636, P 0.006), (χ2 = 9.245, P = 0.002), and (χ2 = 11.997, P = 0.001), respectively. The frequency of diabetes was significantly higher in patients with migraine with aura than in those without aura (χ2 = 4.248, P value 0.039). CONCLUSION: This study provides a better understanding of the comorbidities in Egyptian patients with migraine and will provide new avenues for developing individualized therapy for migraine patients.

Cost-effectiveness of HARNESS-MRI protocol in focal drug-resistant epilepsy in a limited-resources country: An Egyptian study.

OBJECTIVES: The international league against epilepsy (ILAE) recommended the harmonized neuroimaging of epilepsy structural sequences (HARNESS-MRI) to improve the detection of epileptogenic lesions in patients with focal drug-resistant epilepsy (DRE). The application of this protocol is still limited in low-resource countries, mainly due to apparent high costs. We aimed to evaluate the cost-effectiveness of the HARNESS-MRI protocol in Egypt and highlighted our experience. METHODS: Patients diagnosed with focal DRE at Cairo University epilepsy clinic underwent both conventional MRI (c-MRI) and HARNESS-MRI. Electro-clinical data were collected and analyzed. After the radiologists' initial diagnosis, a multidisciplinary team re-evaluated the MRI. Lesion detection rate and cost for detecting an extra lesion by HARNESS-MRI protocol were calculated. RESULTS: The study included 230 patients with focal DRE (146, 62% males and 91, 38% females), with a mean age of 20.5 years. Epileptogenic lesions detected by c-MRI and HARNESS-MRI before and after the board meeting were 40, 106, and 131 lesions, respectively (P < 0.001). Sixty-nine percent of the lesions detected by HARNESS-MRI were missed on c-MRI; most commonly were mesial temporal sclerosis (MTS) and Malformations of cortical development (MCDs). Thirty-seven MTS and 32 MCDs were detected with HARNESS-MRI, compared to only 6 and 3, respectively, detected on c-MRI (P < 0.001). HARNESS-MR protocol is more cost-effective than c-MRI in detecting MRI lesions; it can save about 42$ for detecting an extra lesion in MRI. CONCLUSION: The HARNESS-MRI protocol was cost-effective and highly recommended even in limited-resource countries for patients with focal DRE.

Resective epilepsy surgery in a limited-resource settings: A cohort from a multi-disciplinary epilepsy team in a developing country.

Background: Multidisciplinary pre-surgical evaluation is vital for epilepsy surgery decision and outcomes. Resective epilepsy surgery with assisted monitoring is currently a standard treatment for focal drug resistant epilepsy (DRE). In resource-limited countries, lack of epilepsy surgery center is a huge challenge. We presented and illustrated how to create a multidisciplinary protocol with resource-limited settings in a developing country and epilepsy surgery outcome using brain mapping and monitoring techniques for ensuring satisfactory resection. Methods: We created multicentric incomplete but complementary units covering all epilepsy-related sub-specialties and covering a wide geographical area in our country. Then, we conducted a prospective and multicentric study with low resource settings on patients with focal DRE, who underwent resective epilepsy surgery and were followed up for at least 12 months and were evaluated for postoperative seizure outcome and complications if present. Preoperative comprehensive clinical, neurophysiological, neuropsychological, and radiological evaluations were performed by multidisciplinary epilepsy team. Intraoperative brain mapping including awake craniotomy and direct stimulation techniques, neurophysiological monitoring, and electrocorticography was carried out during surgical resection. Results: The study included 47 patients (18 females and 29 males) with mean age 20.4 ± 10.02 years. Twenty-two (46.8%) patients were temporal epilepsy while 25 (53.2%) were extra-temporal epilepsy. The epilepsy surgery outcome at the last follow up was Engel Class I (seizure free) in 35 (74.5%), Class II (almost seizure free) in 8 (17%), Class III (worthwhile improvement) in 3 (6.4%), and Class IV (no worthwhile improvement) in 1 patient (2.1%). Conclusion: With low resource settings and lack of single fully equipped epilepsy center, favorable outcomes after resective surgery in patients with focal DRE could be achieved using careful presurgical multidisciplinary selection, especially with using intraoperative brain mapping and electrocorticography techniques.

Non-convulsive status epilepticus in Sotos syndrome: rare first presentation in a rare syndrome.

INTRODUCTION: Prior to illustration of the causative genetic mutation responsible for Sotos syndrome, diagnosis was based on clinical criteria. They include characteristic facial gestalt, developmental delay, and evidence of overgrowth, in addition to other minor features as cardiac &genitourinary congenital malformation, seizures, scoliosis, among other features. Non-convulsive status epilepticus (NCSE) was not previously reported among Sotos patients. CASE SUMMARY: An eleven-years old boy, with developmental delay, characteristic facial & skeletal features presented to the emergency department with a two-hour episode of lapse of consciousness. Electroencephalogram (EEG) showed fluctuating generalized spike-wave/poly-spike wave discharge <2.5 Hertz (Hz), lasting throughout the duration of recording. Intravenous (IV) levetiracetam was associated with clinical & EEG improvement & accordingly the patient was diagnosed as NCSE. The mother reported history of polyhydramnios, febrile seizure & developmental delay. Through clinical & radiological assessment revealed generalized hypotonia, low intelligence quotient (IQ), congenital ureteric stricture & pulmonary hypertension, prominent retro-cerebellar cistern, in addition to scoliosis & facial features suggestive of Sotos Syndrome. Six months after presentation, the patient remained seizure free on levetiracetam monotherapy. CONCLUSION: NCSE could occur in Sotos syndrome. In our case, the first reported case of NCSE in Sotos syndrome, the characteristic facial & skeletal findings initiated further work up with fulfillment of the criteria required for the clinical diagnosis of Sotos syndrome.

Neurological Manifestations in a Cohort of Egyptian Patients with COVID-19: A Prospective, Multicenter, Observational Study.

BACKGROUND: The COVID-19 pandemic has reached over 276 million people globally with 5.3 million deaths as of 22nd December 2021. COVID-19-associated acute and long-term neurological manifestations are well recognized. The exact profile and the timing of neurological events in relation to the onset of infection are worth exploring. The aim of the current body of work was to determine the frequency, pattern, and temporal profile of neurological manifestations in a cohort of Egyptian patients with confirmed COVID-19 infection. METHODS: This was a prospective study conducted on 582 hospitalized COVID-19 patients within the first two weeks of the diagnosis of COVID-19 to detect any specific or non-specific neurological events. RESULTS: The patients' mean (SD) age was 46.74 (17.26) years, and 340 (58.42%) patients were females. The most commonly encountered COVID-19 symptoms were fever (90.72%), cough (82.99%), and fatigue (76.98%). Neurological events (NE) detected in 283 patients (48.63%) and were significantly associated with a severe COVID-19 at the onset (OR: 3.13; 95% CI: 2.18-4.51; p < 0.0001) and with a higher mortality (OR: 2.56; 95% CI: 1.48-5.46; p = 0.019). The most frequently reported NEs were headaches (n = 167) and myalgias (n = 126). Neurological syndromes included stroke (n = 14), encephalitis (n = 12), encephalopathy (n = 11), transverse myelitis (n = 6) and Guillain-Barré syndrome (n = 4). CONCLUSIONS: Neurological involvement is common (48.63%) in COVID-19 patients within the first two weeks of the illness. This includes neurological symptoms such as anosmia, headaches, as well as a constellation of neurological syndromes such as stroke, encephalitis, transverse myelitis, and Guillain-Barré syndrome. Severity of acute COVID-19 illness and older age are the main risk factors.

Changes in migraine characteristics over 30 days of Ramadan fasting: A prospective study.

OBJECTIVE: To study Ramadan's effect on migraine from the start to the end of the month and the tolerability of patients with migraine to fasting. BACKGROUND: Fasting is a well-known trigger for migraine. Whether this effect on migraine is the same throughout the whole month, or whether it varies from the first to the last days of the month, has not been studied yet. METHODS: A prospective cohort observational study was carried out on persons with migraine who fasted from 24 April to 23 May during Ramadan 2020. Each patient was asked to fill out their headache diary starting from Shaaban (the month before Ramadan) to the end of Ramadan. The Ramadan diary was divided by 10 days each, by which the patient was asked to accurately describe their migraine attacks in terms of frequency, duration, and intensity by using the Visual Analog Scale. Migraine attacks during the first day of fasting were assessed separately. RESULTS: A total of 292 known persons with migraine from Egypt completed the study. Their median age was 33 years; 72/292 (24.7%) were male, and 220/292 (75.3%) were female. About 126/236 (53.4%) of the patients had migraine attacks on Ramadan's first day, most of them during fasting. The frequency of migraine attacks was significantly increased in Ramadan (median 4, interquartile range [IQR] 2-7) compared with Shaaban (median 3, IQR 1-6), p = 0.009. The number of attacks was significantly reduced in both the second (median 1, IQR 0-2.25) and the third 10 days of Ramadan (median 1, IQR 1-3) compared with the first 10 days (median 3, IQR 1-5) (p < 0.001 for each). CONCLUSION: Ramadan's potential exacerbating effect on the frequency of migraine attacks should be discussed with patients with migraine. This effect appears to be limited to the first 10 days of Ramadan and then subsides with successive days of fasting.

Characteristics and outcome in an Egyptian Cohort with status epilepticus.

OBJECTIVES: Status epilepticus (SE) is an important cause of mortality worldwide. Information regarding associations of mortality outcome in Egypt is limited. The main objective of this study was to describe the clinical characteristics and factors associated with mortality of patients with SE admitted to Cairo University Hospitals. METHODS: A prospective observational hospital-based study was conducted from January 2017 to June 2018. Patients with SE aged ≥12 years old were followed with documentation of outcome on discharge as survival versus death. RESULTS: The study cohort included 144 SE patients. The majority of episodes (96.5%) were with prominent motor features, while nonconvulsive SE occurred in 3.5%. There was a clear semiology evolution in 22.9% of episodes, 56.3% had unchanging semiology (e.g., just convulsive or just nonconvulsive) and the semiology evolution could not be discerned in 20.8%. In relation to treatment, the majority of cases were responsive (46.5%), whereas 43.1% were refractory and only 10.4% were super-refractory SE. Apart from seven patients who were referred to other hospitals, 99 patients survived whereas 38 (26.4%) died. After regression analysis, only absence of a history of epilepsy, semiology evolution and mechanical ventilator use were associated with mortality increasing its odds by 3.7, 5, 111 times, respectively. CONCLUSION: Absence of a history of epilepsy, SE semiology evolution, and mechanical ventilator use was found to be associated with mortality outcome among Egyptian patients with SE.

Management Strategies of Patients with Neuromyelitis Optica Spectrum Disorder During the COVID-19 Pandemic Era.

The ongoing coronavirus (COVID-19) pandemic is a global health emergency of international concern and has affected management plans of many autoimmune disorders. Immunosuppressive and immunomodulatory therapies are pivotal in the management of neuromyelitis optica spectrum disorder (NMOSD), potentially placing patients at an increased risk of contracting infections such as COVID-19. The optimal management strategy of NMOSD during the COVID-19 era remains unclear. Here, however, we examined the evidence of NMOSD disease-modifying therapies (DMTs) use during the present period and highlighted different scenarios including treatment of relapses as well as initiation and maintenance of DMTs in order to optimize care of NMOSD patients in the COVID-19 era.

The EEG diagnosis of NCSE: Concordance between clinical practice and Salzburg Criteria for NCSE.

PURPOSE: To evaluate the concordance between the EEG diagnosis of non-convulsive status epilepticus (NCSE) made by the treating physician and the application of the Salzburg Consensus Criteria (SCC) on consecutive urgent EEG requested for acute alteration of consciousness not otherwise explained. METHODS: Retrospective evaluation of all urgent EEGs acquired between January 1st and March 31st 2018 in adolescents and adult patients (≥14 years old). The 'reference' was the neurologist who first evaluated the patient and reported the corresponding EEG diagnosis. All were blind to the SCC. All included EEG were evaluated and classified by three neurologists trained in the application of SCC blind to the clinical diagnosis. RESULTS: 181 consecutive EEGs entered the study. The treating clinician diagnosed a NCSE in 17 cases (9%). According to the SCC, 12 EEGs were classified as Definite NCSE (7%), 71 (39 %) as Possible NCSE, and 98 (54 %) as no NCSE. A perfect concordance was found for the Definite- and No-NCSE categories, while only 5 patients with a Possible-NCSE were diagnosed by the treating clinician as having NCSE. It is relevant to note that aamong the 66 patients with a Possible NCSE not diagnosed as SE by the treating clinician, only two presented an evolution toward a definite SE. CONCLUSION: SCC have optimal performances for the 'Definite NCSE', and to exclude the presence of a NCSE. Conversely, the Possible NCSE category is still a a grey land of debate that could potentially include many different conditions.

External validation of STESS and EMSE as outcome prediction scores in an Egyptian cohort with status epilepticus.

PURPOSE: There is a lack of data concerning the performance of the outcome prediction scores in patients with status epilepticus (SE) in developing countries. The aim of this study was to compare the predictive performances of the status epilepticus severity score (STESS) and the epidemiology-based mortality score in status epilepticus (EMSE) and adaptation of such scoring system to be compatible with the nature of society. METHOD: This is a prospective study, conducted in Egypt from the period of January 2017 to June 2018. The main outcome measure was survival versus death, on hospital discharge. The cutoff point with the best sensitivity and specificity to predict mortality was determined through a receiver operating characteristic (ROC) curve. RESULTS: Among the 144 patients with SE with a mean age of 39.3 ±â€¯19.5 years recruited into the study, 38 patients (26.3%) died in the hospital with the survival of 99 patients while 7 patients (4.9%) were referred to other centers with an unknown outcome. Although EMSE had a bit larger area under the curve (AUC) (0.846) than STESS-3 (AUC 0.824), STESS-3 had the best performance as in-hospital death prediction score as it has a higher negative predictive value (94.6%) than that of EMSE (90.9%) in order not to miss high-risk patients. CONCLUSION: In the Egyptian population, STESS and EMSE are useful tools in predicting mortality outcome of SE. The STESS performed significantly better than EMSEE combinations as a mortality prediction score.
