Consensus Guideline on the Management of Epilepsy in Egypt: A National Delphi Consensus Study.

OBJECTIVE: In epilepsy, early diagnosis, accurate determination of epilepsy type, proper selection of antiseizure medication, and monitoring are all essential. However, despite recent therapeutic advances and conceptual reconsiderations in the classification and management of epilepsy, serious gaps are still encountered in day-to-day practice in Egypt as well as several other resource-limited countries. Premature mortality, poor quality of life, socio-economic burden, cognitive problems, poor treatment outcomes, and comorbidities are major challenges that require urgent actions to be implemented at all levels. In recognition of this, a group of Egyptian epilepsy experts met through a series of consecutive meetings to specify the main concepts concerning the diagnosis and management of epilepsy, with the ultimate goal of establishing a nationwide Egyptian consensus. METHODS: The consensus was developed through a modified Delphi methodology. A thorough review of the most recent relevant literature and international guidelines was performed to evaluate their applicability to the Egyptian situation. Afterward, several remote and live rounds were scheduled to reach a final agreement for all listed statements. RESULTS: Of 278 statements reviewed in the first round, 256 achieved ≥80% agreement. Live discussion and refinement of the 22 statements that did not reach consensus during the first round took place, followed by final live voting then consensus was achieved for all remaining statements. SIGNIFICANCE: With the implementation of these unified recommendations, we believe this will bring about substantial improvements in both the quality of care and treatment outcomes for persons with epilepsy in Egypt. PLAIN LANGUAGE SUMMARY: This work represents the efforts of a group of medical experts to reach an agreement on the best medical practice related to people with epilepsy based on previously published recommendations while taking into consideration applicable options in resource-limited countries. The publication of this document is expected to minimize many malpractice issues and pave the way for better healthcare services on both individual and governmental levels.

Reliability, validity, and responsiveness of the Arabic version of HIT-6 questionnaire in patients with migraine indicated for preventive therapy: A multi-center study.

BACKGROUND: The Headache Impact Test (HIT-6) is an important patient-reported outcome measure (PROM) in migraine prevention trials. OBJECTIVES: This study aimed to (i) assess the reliability and validity of the Arabic version of HIT-6 in Arabic-speaking patients experiencing migraine, and (ii) evaluate the responsiveness of HIT-6 following migraine preventive therapy. METHODS: In this prospective study, patients with migraine (n = 145) were requested to fill out a headache diary, the Arabic version of HIT-6, and Migraine Disability Assessment Scale (MIDAS) at two time points (baseline and 3 months after initiation of prophylactic treatment). Some respondents (n = 73) were requested to fill out HIT-6 again 1 week from the baseline for test-retest reliability. The intensity of migraine headache attacks was evaluated using the Visual Analogue Scale (VAS). An anchor-based method was used to establish the minimal important change (MIC) value and responsiveness of HIT-6. RESULTS: The total scores of HIT-6 were significantly correlated to a fair degree with MIDAS (r = 0.41), as well as VAS (r = 0.53), and monthly migraine days (r = 0.38) at the baseline while at the follow-up (after 3 months), the correlations were of moderate degree with MIDAS scores (r = 0.62) and monthly migraine days (r = 0.60; convergent validity). Reliability estimates of the Arabic HIT-6 were excellent (Cronbach's α = 0.91 at baseline and 0.89 at follow-up). The average measure interclass correlation coefficient (ICC) value for the test-retest reliability was 0.96 (95% confidence interval = 0.94-0.98, p < 0.001). The HIT-6 total score is sensitive to change, being significantly reduced after prophylactic treatment compared to before (effect size = 1.5, standardized response mean = 1.3). A reduction from baseline of 4.5 on HIT-6 showed the highest responsiveness to predict improvement with an area under the curve equal to 0.66, sensitivity of 80%, specificity of 45%, and significance at 0.021. Changes in the HIT-6 total score were positively correlated with changes in monthly migraine days (r = 0.40) and VAS scores (r = 0.69) but not with changes in the score of MIDAS (r = 0.07). CONCLUSION: The Arabic version of HIT-6 is valid, reliable, and sensitive to detect clinical changes following migraine prophylactic treatment with a MIC of 4.5 points.

Predictive value of S100B and brain derived neurotrophic factor for radiofrequency treatment of lumbar disc prolapse.

BACKGROUND: This work aimed to analyze serum S100B levels and brain-derived neurotrophic factor (BDNF) in patients with lumbar disc prolapse to test their predictive values concerning the therapeutic efficacy of pulsed radiofrequency. METHODS: This prospective interventional study was carried out on 50 patients candidates for radiofrequency for treating symptomatic lumbar disc prolapse. Pain severity and functional disability were assessed using the Numeric Rating Scale (NRS) and Functional rating index (FRI) before as well as two weeks, 1, 3, and 6 months after the radiofrequency. Quantitative assessment of serum S100B level and BDNF was done for all the included patients one day before radiofrequency. RESULTS: The scores of NRS and FRI were significantly improved at two weeks, 1, 3, and 6 months following radiofrequency (P-value < 0.001 in all comparisons). Statistically significant positive correlations were found between duration of pain, NRS, and S100B serum level before radiofrequency, and both NRS (P-value = 0.001, 0.035, < 0.001 respectively) and FRI (P-value = < 0.001, 0.009, 0.001 respectively) 6 months following radiofrequency. Whereas there were statistically significant negative correlations between BDNF serum level before radiofrequency and both NRS and FRI 6 months following radiofrequency (P-value = 0.022, 0.041 respectively). NRS and S100B serum levels before radiofrequency were found to be independent predictors of NRS 6 months following radiofrequency (P-value = 0.040. <0.001, respectively). CONCLUSION: Serum level of S100B is a promising biomarker that can predict functional outcomes after pulsed radiofrequency in patients with lumbar disc prolapse.

Public misconceptions and attitudes towards persons diagnosed with epilepsy in the Kingdom of Bahrain: A cross-sectional study.

BACKGROUND: Despite significant advancements in the understanding and treatment of epilepsy, the quality of life for persons diagnosed with Epilepsy (PdwE) can still be negatively impacted due to prevalent misconceptions and societal attitudes. This study aimed to investigate the knowledge, misconceptions, and attitudes towards epilepsy in Bahrain. METHODS: This cross-sectional study involved 1079 participants aged ≥ 18 years living in Bahrain. Data collection occurred between June and December 2023 through an online questionnaire. The questionnaire consisted of four sections: sociodemographic characteristics, sources of information, knowledge about epilepsy, and attitudes toward PdwE. RESULTS: Most participants (1063 out of 1179) were familiar with epilepsy, with social media being the main source of information (56.7%). While 75.6% correctly recognized epilepsy as a nervous system disorder. About 30% of participants believed that body shaking and falling to the ground were the only types of seizures. In terms of attitudes, 47.9% believed that PdwE could achieve high levels of education, but 40% thought they might face job loss due to their condition. Additionally, 27.5% disagreed with the idea of marrying someone with epilepsy or allowing a family member to do so. Being female, young, highly educated, and having a family member with epilepsy were associated with significantly more positive attitudes compared to other groups. CONCLUSION: The studied sample of the Bahraini public demonstrated a satisfactory level of knowledge about epilepsy. However, they still held certain misconceptions that could impact their attitudes towards PdwE. Community awareness campaigns can address this knowledge gap and reduce epilepsy stigma.

Impact of Ramadan fasting on vision and headache-related quality of life in women with idiopathic intracranial hypertension: A prospective observational study.

BACKGROUND: Ramadan fasting is an obligatory religious practice for Muslims. However, research data on the effect of Ramadan on idiopathic intracranial hypertension (IIH) symptoms are lacking. This study aimed to study the effect of Ramadan fasting on the severity of headache and visual symptoms and related quality-of-life activities. METHODS: This prospective cohort study targeted females diagnosed with IIH (n = 102) who were eligible to fast for Ramadan in 2023. The patients were recruited from the Neurology Clinic in Beni-Suef University Hospital, Egypt. Body mass index (BMI), monthly headache days and intensity of headache attacks, six-item Headache Impact Test (HIT-6), and the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) scores during Ramadan were compared to those during the (non-fasting) month of Shaaban, the preceding month to Ramadan. RESULTS: There was a significant increase in the BMI of patients with IIH in Ramadan compared to the (non-fasting) month of Shaaban, at a median (interquartile range [IQR]) of 30.5 (26.6-35.8) kg/m2 and 30.1 (26.6-35.2) kg/m2, respectively (p = 0.002). The median (IQR) value of monthly headache days was significantly increased during Ramadan in comparison to the (non-fasting) month of Shaaban, at 20 (11.5-30) vs. 15 (10-25) (p < 0.001). There was a statistically significant worsening in the visual analog scale (VAS) scores (median [IQR] 7 [5-8] vs. 6.5 [5-8]), HIT-6 scores (median [IQR] 61 [58-67] vs. 59 [53-61.5]), and NEI-VFQ-25 total scores (median [IQR] 1312.5 [1238.8-1435] vs 1290 [1165-1417.5]) during Ramadan in comparison to the (non-fasting) month of Shaaban (p < 0.001 for all comparisons). The change in BMI in Ramadan was positively correlated with the change in monthly headache days (r = 0.24, p = 0.014), VAS (r = 0.20, p = 0.043), HIT-6 (r = 0.25, p = 0.010) and NEI-VFQ-25 scores (r = 0.24, p = 0.016). CONCLUSION: Ramadan fasting had an aggravating effect on headache, visual symptoms, and related quality-of-life activities, which might be attributed to weight gain during this month. Whether proper nutritional management to prevent weight gain during Ramadan may help mitigate this worsening effect is a mission of future studies.

Cognitive function and quantitative electroencephalogram analysis in subjects recovered from COVID-19 infection.

BACKGROUND & OBJECTIVES: Objective assessment of post-COVID-19 cognitive dysfunction is highly warranted. This study aimed to evaluate the cognitive dysfunction of COVID-19 survivors with cognitive complaints, both clinically and neurophysiologically, using Quantitative Electroencephalogram (QEEG). METHODS: This case-control study was conducted on 50 recovered subjects from COVID-19 infection with cognitive complaints and 50 age, sex, and educational-matched healthy controls. Both groups were subjected to the following neurocognitive tests: Paired associate learning Test (PALT) and Paced Auditory Serial Addition Test (PASAT). The neurophysiological assessment was also done for both groups using QEEG. RESULTS: COVID-19 survivors had significantly lower PALT scores than controls (P < 0.001). QEEG analysis found significantly higher levels of Theta / Beta ratio in both central and parietal areas in patients than in the controls (P < 0.001 for each). The interhemispheric coherence for the frontal, central, and parietal regions was also significantly lower in patients than in the control group regarding alpha and beta bands. There were statistically significant lower scores of PALT and PASAT among cases with severe COVID-19 infection (P = 0.011, 0.005, respectively) and those who needed oxygen support (P = 0.04, 0.01, respectively). On the other hand, a statistically significantly lower mean of frontal alpha inter-hemispheric coherence among patients with severe COVID-19 infection (P = 0.01) and those needing mechanical ventilation support (P = 0.04). CONCLUSION: Episodic memory deficit is evident in COVID-19 survivors with subjective cognitive complaints accompanied by lower inter-hemispheric coherence in frontal regions. These clinical and neurophysiological changes are associated with hypoxia and COVID-19 severity.

Validity and reliability of Arabic version of pediatric migraine disability assessment scale (Child Self-Report versus Parent Proxy-Report): a multi-center study.

BACKGROUND: Pediatric Migraine Disability Assessment (PedMIDAS) is one of the most frequently used questionnaires to assess disability from migraine in pediatric patients. This work aimed to evaluate the validity and test-retest reliability of the Arabic version of the child self-report versus the parent proxy report PedMIDAS. We also aimed to test the agreement between children's and parents' reports of the scale. METHODS: PedMIDAS was subjected to translation and back-translation, then applied to 112 pediatric patients fulfilling the migraine diagnostic criteria. This cross-sectional study was conducted on two visits, one week apart. At visit 1, the following data were obtained from the included pediatric patients: disease duration, migraine type, current treatment regimen, monthly migraine days (MMD) during the last month preceding the enrollment, and migraine intensity using the visual analogue scale. Then, each child and his parent were independently asked to fill out PedMIDAS and Child Self-Report of the Pediatric Quality of Life Inventory™ 4.0 (PedsQL™) to test the convergent validity of PedMIDAS. At visit 2, each child was requested to complete PedMIDAS again, and so was the parent to evaluate test-retest reliability. RESULTS: Cronbach's alpha was estimated to be 0.94 for each instrument. For the child-self report PedMIDAS, the average measure intraclass correlation coefficient (ICC) value was 0.992 (95%CI = 0.989-0.995), while it was estimated to be 0.990 for the parent-proxy report with 95%CI = 0.985-0.993, indicating excellent test-retest reliability for both instruments. The child-self report and the parent-proxy report PedMIDAS scores were significantly correlated with MMD, VAS, and all domains of the corresponding PedsQL, supporting convergent validity for both instruments. Agreement between parent and child on disability grading categories of PedMIDAS was substantial (κ = 0.644). CONCLUSION: The Arabic version of PedMIDAS was a valid and reliable instrument to assess disability from migraine in Arabic-speaking pediatric patients with migraine. Parent reports can be valuable as a complement to child reports for a comprehensive assessment of migraine.

Substance use disorder in young adults with stroke: clinical characteristics and outcome.

OBJECTIVE: Stroke incidence among young adults has risen in the last decade. This research attempts to determine the effect of substance use disorder (SUD) on the clinical characteristics of stroke, mortality, outcome after IV thrombolysis, and functional dependency after 1 month among young adults. METHODS: Through a retrospective study, data were extracted from the electronic medical records of stroke in young adults admitted to intensive care units in Kasr Al-Ainy Hospital (February 2018-January 2021). The National Institute of Health Stroke Scale (NIHSS) and the Modified Rankin Scale were documented at the onset and after 1 month. RESULTS: The study included 225 young adults with stroke (median age of 40, IQR: 34-44). Only 93 young adults (41%) met the criteria of SUD. Anabolic steroid use disorder was significantly associated with cerebral venous thrombosis (P-value = 0.02), while heroin use disorder was significantly associated with a hemorrhagic stroke (P-value = 0.01). Patients with tramadol, cannabis, and cocaine use disorders had significantly more frequent strokes in the posterior than the anterior circulation. Patients with heroin use disorders had significantly higher mortality than those without heroin use disorders (P-value = 0.01). The risk of poor outcomes was doubled by alcohol or heroin use disorder, while it was tripled by cocaine use disorder (P-value = 0.01 for each). CONCLUSION: Forty-one percent of young adults diagnosed with a stroke had SUD, with a relatively higher posterior circulation involvement. Increased mortality was associated with heroin use disorder more than other substances. Poor stroke outcome was associated with alcohol, heroin, and cocaine use disorders.

Effect of Radiofrequency on Dorsal Root Ganglion Versus Transforaminal Steroids Injection on Tumor Necrosis Factor-Alpha Level in Lumbar Radicular Pain.

BACKGROUND: The mechanism of pain control with pulsed radiofrequency (PRF) is unclear. OBJECTIVES: We aimed to compare the efficacy of combined PRF on dorsal root ganglion (DRG) with transforaminal epidural steroid injection (TFESI) vs TFESI-alone on pain improvement and serum tumor necrosis factor-alpha (TNF-a) level in lumbar disc-related radicular pain. STUDY DESIGN: Prospective, randomized, controlled trial. SETTING: Neurology and Pain Management clinics. METHODS: A total of 80 patients with lumbar disc prolapse were divided into 2 groups: combined PRF on DRG with TFESI group and TFESI-alone group. The Numeric Rating Scale (NRS-11), Oswestry Disability Index (ODI), and Functional Rating Index (FRI) before intervention and at 2 weeks, 1 month, and 3 months after the intervention were observed. Serum TNF-a level was assessed pre- and post-intervention at 3 months. RESULTS: The scores of NRS-11, ODI, and FRI showed a significant improvement at 2 weeks, 1 month, and 3 months following intervention in both combined PRF & TFESI group and TFESI-alone group (P < 0.001 in all comparisons), with no significant difference between the 2 groups. Serum TNF-a levels showed a statistically significant reduction, 3 months following intervention in the combined PRF & TFESI group (P < 0.001), but not in the TFESI-alone group (P = 0.297) (P between groups < 0.001). LIMITATIONS: The main limitation of this study is that TNF-a level was not assessed earlier to see how long the steroids might reduce TNF-a. On the other hand, further study with extended follow-up periods is needed to confirm the long-term lowering effect of TNF-a provided by PRF. CONCLUSIONS: Combined PRF on DRG with TFESI showed similar outcomes to TFESI-alone in relieving pain in patients with lumbar disc prolapse. However, PRF on DRG caused a significant decrease in TNF-a serum levels at 3 months.

Knowledge, awareness, and attitudes towards epilepsy among elementary schoolteachers in the Kingdom of Bahrain.

BACKGROUND: Teachers' awareness of epilepsy and attitudes toward students with epilepsy (SWE) largely affect their health, behavior, and academic performance. This study aimed to assess elementary schoolteachers' background knowledge and attitudes toward epilepsy in the Kingdom of Bahrain. METHODS: A 23-item online questionnaire was distributed to elementary school teachers in all public schools in Bahrain between September 2022 and February 2023. The questionnaire included three sets of questions about teachers'1) demographics and teaching experience, 2) knowledge and experience with epilepsy, and 3) attitude towards SWE. RESULTS: Three hundred and sixty-seven teachers responded to the questionnaire. Only 82 participants (22.3%) thought they had enough information about epilepsy. Approximately 25% had previously taught SWE. Even though 9.3% have witnessed a seizure before, only 2.2% received seizure first aid training courses. Most respondents (68.7%) knew that epilepsy is caused by abnormal brain electrical activity and is not contagious (95.1%). Regarding seizure types, 76.6% were aware of uncontrollable jerky movements, while staring spells were recognized by 45%. Most first-aid responses were inappropriate, as 59.7% would open the patient's mouth. Only 39.5% agreed on patient transfer to the hospital if the seizure lasted ≥5 min. Epilepsy was thought to cause mental retardation by 32.4%. Also, the belief that SWE were more prone to bullying was reported by 57.2%. CONCLUSION: The knowledge and attitudes of schoolteachers in Bahrain towards epilepsy are relatively good but with remaining improvement potential. They do not fully grasp all seizure types nor adequate first-aid measures promoting future epilepsy educational programs.

Patterns and predictors of sexual dysfunction in women with epilepsy.

OBJECTIVES: Available data about sexual-related problems among Egyptian women with epilepsy (WWE) are scarce. Hence, this work aimed to study the pattern and predictors of sexual dysfunction in a sample of Egyptian WWE. METHODS: In this cross-sectional study, sexually active WWE and age and years of marriage-matched healthy controls were included. The Female Sexual Function Index questionnaire (FSFI) was used to assess sexual function in both groups. RESULTS: In the patient group (n = 142), the median age was 33 (28-39), whereas the median age of the control group (n = 142) was 33.5 (28-36). Women with epilepsy had significantly lower desire, arousal, pain, and FSFI-total scores than the control group (P = 0.001, 0.001, 0.023, 0.008, respectively). There was a significant difference between the FSFI-total score of women on polytherapy and those on monotherapy (P = 0.042), as well as between those on enzyme-inducing ASMs and those on ASMs that did not affect P450 (P = 0.032). Seizure frequency in the last three months was negatively correlated with scores of desire, arousal, lubrication, orgasm, and satisfaction (P 0.047, 0.02, 0.009, 0.013, 0.046, respectively). By multiple backward linear regression models, age, and seizure frequency were the significant predictors of the FSFI-total score (B -0.219, -0.33, respectively). CONCLUSION: The pattern of sexual dysfunction among Egyptian WWE is characterized by reduced sexual desire, arousal deficits, and sexual-related pain. Seizure frequency, epilepsy duration, enzyme-inducing medications, and multiple anti-seizure medications (ASMs) may adversely affect WWE's sexual health. The only factor that could predict higher sexual dysfunction in WWE was higher seizure frequency.

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.

Migraine in bipolar disorder and schizophrenia: The hidden pain.

OBJECTIVE: This study examined the prevalence of comorbid migraine in patients with bipolar disorder and those with schizophrenia and also examined the association between migraine comorbidity and disease characteristics in both disorders. METHODS: In this cross-sectional study, 150 patients with bipolar disorder and 150 with schizophrenia were evaluated for migraine diagnosis using the International Classification of Headache Disorders (3rd ed). Patients were selected from psychiatry outpatient clinics at Kasr Al Ainy hospitals, Cairo University.  The Young Mania Rating Scale (YMRS) and the Hamilton Depression Rating Scale (HDRS) were administered to the bipolar group, whereas the Positive and Negative Syndrome Scale (PANSS) was administered to the schizophrenia group. Both groups were evaluated by the Clinical Global Impressions (CGI) scale. RESULTS: The diagnosis of migraine was made in 34 (22.7%) of the bipolar group and 24 (16.0%) of the schizophrenia group. Patients with schizophrenia showed a significantly higher frequency and intensity of migraine attacks on the Migraine Disability Assessment scale than did the bipolar group (p < 0.001). In the bipolar group, there was no significant difference between patients with and without migraine on the YMRS, HDRS, and CGI. Among patients with schizophrenia, the duration of the migraine attacks was positively correlated with CGI scores (r = 0.40, p = 0.02). CONCLUSION: Migraine was found to be a significant comorbidity in patients with bipolar disorder and schizophrenia. However, the intensity and frequency of migraine attacks were higher in the schizophrenia than in the bipolar group.

Neurophysiological visual assessment in patients with idiopathic intracranial hypertension: visual evoked potential and multifocal field electroretinography.

BACKGROUND: Determining the cause of visual deterioration in idiopathic intracranial hypertension (IIH) patients is of clinical necessity. This study aimed to study the effect of chronic increased ICP on the retina and optic nerve through objective electrophysiological measures in chronic IIH patients. METHODS: Thirty patients with chronic IIH and thirty age and sex-matched healthy controls were included in this study. Papilledema grade and CSF pressure were evaluated in the patients' group. Both groups were submitted to visual evoked potentials (VEP) and multifocal electroretinogram (mfERG). RESULT: The mean value of P100 latencies of the right and left on two check sizes, 1 deg and 15m in chronic IIH patients, was significantly delayed than controls (P-value < 0.001 for each). Chronic IIH patients showed a significantly lower amplitude of the right and left R1, R2, R3, R4 & R5 compared to controls (P-value < 0.001, < 0.001) (P-value < 0.001, < 0.001) (P-value < 0.001, < 0.001) (P-value < 0.001, = 0.001) (P-value = 0.002, < 0.001), respectively. Also, patients showed a significantly delayed peak time of the right and left R1 and R2 compared to controls (P-value < 0.001, < 0.001) (P-value = 0.001, = 0.009), respectively. There was a significant positive correlation between each of CSF pressure and papilledema grade with right and left PVEP latencies. In contrast, there was no statistically significant correlation between either CSF pressure or papilledema grade and PVEP amplitudes in both eyes. CONCLUSION: In chronic IIH patients, both optic nerve dysfunction and central retinal changes were identified, supported by VEP and the mfERG findings.

Comparative effect of deliberate hypotensive anesthesia using nitroglycerine vs. phentolamine on event related potentials and cognitive functions in patients undergoing septoplasty: a randomized controlled trial.

BACKGROUND: Postoperative cognitive dysfunction is a noteworthy complication of deliberate hypotensive anesthesia. The aim of this work was to compare the effect of deliberate hypotensive anesthesia using nitroglycerine versus phentolamine on event-related potentials and cognitive function in patients undergoing septoplasty surgery. METHODS: This prospective randomized controlled trial was conducted on 80 patients indicated for septoplasty under general anesthesia; 40 patients received intra-operative Nitroglycerine and 40 patients received intra-operative Phentolamine. Cognitive assessment (using Paired Associate Learning test (PALT) and Benton Visual Retention test (BVRT)) and P300 recording were done for all included patients pre-operatively and one week postoperatively. RESULTS: The scores of PALT and Benton BVRT significantly declined one week following surgery in both Nitroglycerine and Phentolamine groups. There was no statistically significant difference between Nitroglycerine and Phentolamine groups in the postoperative decline in either PALT or BVRT (P-value = 0.342, 0.662 respectively). The values of P300 latency showed a significant delay one week following surgery in both Nitroglycerine and Phentolamine groups (P-value ≤ 0.001, 0.001), but in Nitroglycerine group, the delay is significantly higher than in Phentolamine group (P-value = 0.003). The values of P300 amplitude significantly decreased one week following surgery in both Nitroglycerine and Phentolamine groups (P-value ≤ 0.001, 0.001), but there was no statistically significant difference between Nitroglycerine and Phentolamine groups (P-value = 0.099). CONCLUSION: Phentolamine is preferred over nitroglycerin in deliberate hypotensive anesthesia because it has less harmful effect on cognitive function than nitroglycerin.

Prevalence, characteristics, and factors associated with caffeine-withdrawal headache during the first day of Ramadan.

BACKGROUND: Data regarding prevalence, characteristics, and factors associated with caffeine-withdrawal headache are lacking. This work aimed to study the prevalence of caffeine-withdrawal headache among caffeine consumers during Ramadan's first day and describe its characteristics and associated factors. METHODS: This analytical cross-sectional study targeted 755 caffeine consumers eligible to fast on the first day of Ramadan. Two methodological approaches were followed: an online open survey and a face-to-face interview. Using an adjusted form of food frequency questionnaire, eligible participants were requested to report their intake of caffeine-containing products during the last week of Shaaban month, the month preceding Ramadan. RESULTS: The prevalence of caffeine-withdrawal headache on the first day of Ramadan was 419 (55.5%), with 95% confidence interval (CI; 51.9-59.0%). The headache in the majority of the participants was throbbing in character (249/419, 59.4%), diffuse (146/419, 34.8%), and moderate in intensity (227/419, 54.2%). Participants who developed caffeine-withdrawal headache had significantly higher body mass index (27.2 ± 5.1 vs. 26.3 ± 5 [mean ± standard deviation], p-value = 0.012), daily caffeine intake, mg (316 [185.2-537.8] vs. 144.4 [60.0-312.4] [median interquartile range (IQR)], p-value < 0.001), and caffeine intake mg/kg body weight (4.7 [2.6-7.2] vs. 1.9 [0.8-4.4] [median (IQR)], p-value < 0.001) than participants who did not develop it. Mild, moderate, and severe caffeine use disorder were found to have adjusted associations with developing caffeine-withdrawal headache. They increased the odds of headache by 5.3 (95% CI = 3.40-8.3), 10.2 (95% CI = 5.9-17.5), and 15.5 (95% CI = 9.0-26.8) times, respectively. The optimal cut-off value of daily caffeine intake/Kg body weight was determined at 1.97 mg/kg with an area under the curve of 0.722 and sensitivity and specificity of 85.1% and 50.2%, respectively. CONCLUSION: Daily caffeine intake/kg body weight and caffeine use disorder are significantly associated with a caffeine-withdrawal headache.

Seizure control during pregnancy and postpartum period in women with epilepsy: an Egyptian prospective study.

BACKGROUND: Proper seizure control during pregnancy and postpartum is essential to optimize the outcome of women with epilepsy (WWE). The current work aimed to address factors related to seizure occurrence during pregnancy and postpartum. METHODS: One hundred twenty-five WWE, compliant with their anti-seizure medications (ASMs) regimen, were prospectively evaluated for seizure control and ASMs changes all through the pregnancy up to 4 weeks postpartum. RESULTS: Most of the patients, 73 (58.4%), completed their pregnancy without seizures, while 52 (41.6%) had seizures. Only one case developed one episode of convulsive status epilepticus in the third trimester. Due to breakthrough seizures, the ASM dose was increased from the first to the third trimester in 19.2% of pregnancies, while another ASM was added in 8 pregnancies. Uncontrolled seizures during the six months before pregnancy were associated with a four-fold increase in the risk of seizures during pregnancy (95% CI 2.476-6.695). The latter nearly doubled the risk of seizures during the postpartum period (RR 1.978) (95% CI 1.44 -2.717). Furthermore, genetic etiology would increase the risk of seizures during the postpartum period by 2.7 times more than the unknown etiology (RR 2.778, 95%CI 1.156-6.679). CONCLUSION: Women with epilepsy should be counselled that proper seizure control six months before pregnancy is necessary to pass their pregnancy and the postpartum period without seizures.

Neuropsychiatric post-acute sequelae of COVID-19: prevalence, severity, and impact of vaccination.

The potential long-term neuropsychiatric effects of COVID-19 are of global concern. This study aimed to determine the prevalence and predictors of neuropsychiatric post-acute sequelae of COVID-19 among Egyptian COVID-19 survivors and to study the impact of full vaccination before COVID-19 infection on the occurrence and severity of these manifestations. Three months after getting COVID-19 infection, 1638 COVID-19 survivors were screened by phone for possible neuropsychiatric sequelae. Subjects suspected to suffer from these sequelae were invited to a face-to-face interview for objective evaluation. They were requested to rate the severity of their symptoms using visual analogue scales (VAS). The mean age of participants was 38.28 ± 13 years. Only 18.6% were fully vaccinated before COVID-19 infection. Neuropsychiatric post-acute sequelae of COVID-19 were documented in 598 (36.5%) subjects, fatigue was the most frequent one (24.6%), followed by insomnia (16.4%), depression (15.3%), and anxiety (14.4%). Moderate and severe COVID-19 infection and non-vaccination increased the odds of developing post-COVID-19 neuropsychiatric manifestations by 2 times (OR 1.95, 95% CI = 1.415-2.683), 3.86 times (OR 3.86, 95% CI = 2.358-6.329), and 1.67 times (OR 1.67, 95% CI = 1.253-2.216), respectively. Fully vaccinated subjects before COVID-19 infection (n = 304) had significantly lesser severity of post-COVID-19 fatigue, ageusia/hypogeusia, dizziness, tinnitus, and insomnia (P value = 0.001, 0.008, < 0.001, 0.025, and 0.005, respectively) than non-vaccinated subjects. This report declared neuropsychiatric sequelae in 36.5% of Egyptian COVID-19 survivors, fatigue being the most prevalent. The effectiveness of COVID-19 vaccines in reducing the severity of some post-COVID-19 neuropsychiatric manifestations may improve general vaccine acceptance.
