Door-to-door survey of major neurological disorders (project) in Al Quseir City, Red Sea Governorate, Egypt.

A door-to-door survey, including every household, was conducted for all inhabitants of Al Quseir City (33,283), Red Sea Governorate, Egypt by three specialists of neurology as well as nine senior staff members of neurology and 15 female social workers to assess the epidemiology of major neurological disorders. Over six phases, from July 1, 2009 to January 31, 2012, screening of all eligible people in the population was carried out, by which case ascertainment of all major neurological disorders included in the study was done according to the accepted definitions and diagnostic criteria of the World Health Organization. The order of frequency of prevalence of the studied neurological disorders was dementia (3.83% for those aged > 60 years), migraine (2.8% for those aged > 8 years), stroke (6.2/1000 for those aged > 20 years), epilepsy (5.5/1000), Parkinson’s disease (452.1/100,000 for those aged > 40 years), cerebral palsy (3.6/1000 among children < 18 years), spinal cord disorders (63/100,000) dystonia (39.11/100,000), cerebellar ataxia (30.01/100,000), trigeminal neuralgia (28/100,000 for those aged > 37 years), chorea (21.03/100,000), athetosis (15/100,000), and multiple sclerosis (13.74/100,000). The incidence rates of stroke, epilepsy, and Bell’s palsy were 181/100,000, 48/100,000, and 98.9/100,000 per year, respectively.

Trace element, oxidant, and antioxidant enzyme values in blood of children with refractory epilepsy

Purpose: The aim of this study is to evaluate the serum levels of some trace elements, oxidants, and antioxidants in children with intractable epilepsy compared to healthy children. Patients and Methods: In a case–control study, 40 children (24 males and 16 females) suffering from refractory generalized epileptic seizures were compared with 40 sex- and age-matched healthy children serve as a control group. Serum selenium (Se), zinc (Zn), copper (Cu), and plasma malondialdehyde (MDA) as well as erythrocyte glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) values were measured in the patients and controls. Results: Plasma MDA values of the patient group were significantly ( p < 0.001) higher than those in control. Serum Zn, Se, and erythrocyte GSH-Px values of the patient group are significantly ( p < 0.001) lower than those in control, although there is no statistical difference in Cu and SOD values. Conclusion: Plasma MDA, erythrocyte GSH-Px, and trace elements Zn and Se may play an important role in the pathogenesis of intractable epilepsy in children.

Cerebral palsy in Al-Quseir City, Egypt: prevalence, subtypes, and risk factors

Cerebral palsy (CP) is the most frequent cause of motor handicap. The present door-to-door survey was conducted in Al-Quseir City, Egypt, to investigate the epidemiology of CP. All inhabitants were screened by three neurologists. Medical and neurological examinations were performed for all residents and suspected cases of CP were confirmed by meticulous neurological assessment, brain magnetic resonance imaging, electroencephalography, and testing with the Stanford-Binet Intelligence Scale. Forty-six of 12,788 children aged ≤18 years were found to have CP, yielding a childhood prevalence of 3.6 (95% confidence interval 1.48–2.59) per 1,000 live births. Five adults (aged 19–40 years) among 13,056 inhabitants had CP, giving an adult prevalence of 0.4 (95% confidence interval 0.04–0.72) per 1,000. The risk factors for CP identified in this study were premature birth, low birth weight, neonatal jaundice, neonatal seizures, and recurrent abortion in mothers of children with CP.

Epidemiology of uncontrolled epilepsy in the Al-Kharga District, New Valley, Egypt.

BACKGROUND Despite advances in treating epilepsy, uncontrolled epilepsy continues to be a major clinical problem. Therefore, this work aimed to study the epidemiology of uncontrolled epilepsy in Al-Kharga District, New Valley. METHODS This study was carried out in 3 stages via door-to-door screening of the total population (62,583 persons). All suspected cases of epilepsy were subjected to case ascertainment, conventional ElectroEncephaloGraphy (EEG), and the Stanford-Binet Intelligence Scale. Patients who had been receiving suitable anti-epileptic drugs (AEDs) over the previous 6 months and were having active seizures were considered uncontrolled, according to Ohtsuka et al.(23) The patients underwent serum AED level estimation, video EEG monitoring, and brain MRIs. Fifty age- and gender-matched patients with controlled epilepsy were chosen for statistical analysis and compared with true intractable patients. RESULTS A total of 437 patients with epilepsy were identified, 30.7% of whom (n=134/437) were uncontrolled, with a prevalence of 2.1/1000. A total of 52.2% of uncontrolled patients (n=70/134) were inappropriately treated, while 47.8% (n=64/134) were compliant with appropriate treatments. Video monitoring EEG of compliant uncontrolled patients demonstrated that 78.1% patients (n=50/64) had definite epilepsy, while 21.9% (n=14/64) had psychogenic non-epileptic seizures (PNES). A logistic regression analysis revealed that status epilepticus, focal seizures, and mixed seizure types were risk factors for intractability.

Epidemiology of epilepsy in New Valley Governorate, Al Kharga District, Egypt

UNLABELLED Epilepsy is one of the serious neurological disorders which results in profound morbidity and mortality. Although epilepsy has no geographical boundaries, understanding cultural, social, and economic backgrounds is a very important step for interpretation of its epidemiological characteristics. This work aims to study the epidemiological profile of epilepsy in New Valley Governorate and to estimate its magnitude of treatment gap. It was conducted in a door to door survey, including all inhabitants (62,583 subjects), by 3 neurologists to detect any suspected case of focal or generalized epilepsy. All suspected cases were subjected to detailed history, clinical examination, EEG, neuroimaging studies, and estimation of serum drug level if needed. The study revealed that life time prevalence of epilepsy in Al Kharga district is 6.76/1000, with highest peak during early child hood, while that of active epilepsy is 4.99/1000 population. The annual incidence rate is 43.14/100,000, and age specific incidence rate has a U-shaped pattern with two peaks of incidence at early infancy and elderly. Localization-related epilepsy is the most frequently encountered type (53.7%). However the treatment gap of epilepsy in New Valley is similar to that in developing countries (61.5%). CONCLUSION Prevalence and Incidence Rate of epilepsy in New Valley are similar to that in industrialized countries.

Prevalence of Parkinson’s disease and other types of Parkinsonism in Al Kharga district, Egypt

Parkinson’s disease (PD) is a common neurodegenerative disorder in older people. The prevalence of PD varies among ethnic and geographic groups around the world. In this study, we aimed to estimate the prevalence of PD and other types of Parkinsonism in persons aged ≥40 years in the Al Kharga district of Egypt. The study was conducted on the total population of Al Kharga district (62,583 persons) between 2005 and 2009 and involved three neurology specialists and 15 female social workers undertaking a door-to-door survey. Suspected cases of Parkinsonism were subjected to meticulous clinical and neurological examination by three neurology staff members from Assiut University hospital who carried out their examinations separately. Of the total population surveyed, 15,482 persons were aged ≥40 years and 49 of these were identified as having Parkinsonism (prevalence: 316.50 per 100,000 people [95% confidence interval {CI} 240.21–404.98]). Of the 49, 33 fulfilled the diagnostic criteria for PD, giving a prevalence rate of 213.15/100,000 (95% CI 150.51–285.80) while 14 fulfilled those for vascular Parkinsonism, with a prevalence rate of 90.43/100,000 (95% CI 49.60–137.78). Postencephalitic and unspecified Parkinsonism each had a prevalence rate of 6.46/100,000. The prevalence of Parkinsonism was found to increase steadily with age, and the prevalence of all types of Parkinsonism was statistically higher in rural compared with urban communities, with no significant difference between men and women.

Prevalence of trigeminal neuralgia in Al-Quseir city (Red sea Governorate), Egypt

BACKGROUND Trigeminal neuralgia or tic douloureux is sometimes described as the most excruciating pain known to humanity. OBJECTIVES To estimate the prevalence of trigeminal neuralgia among the population of Al-Quseir city. METHODS This study forms a part of door to door survey of major neurological disorders in Al-Quseir city, Red sea governorate, Egypt. The total population (33,285 persons) were screened through door to door (every door) by three specialists of Neurology and fifteen female social workers. Then, positive cases were subjected to clinical and neurological examination by other three staff members of neurology. Cases were identified as suffering from trigeminal neuralgia according to the diagnostic criteria of the International headache society (IHS). RESULTS We identified 4 female patients out of 13,541 persons (aged 30 years and more) suffering from trigeminal neuralgia with age specific prevalence rate of 29.5/100,000. Co-morbid depression and hypertension were observed among the affected persons.

Role of short-term out patient video electroencephalography in diagnosis of paroxysmal disorders.

BACKGROUND To distinguish epileptic seizures from non-epileptic paroxysmal events, we often use video electroencephalography (EEG) recording. Long-term video electroencephalography recording for inpatients is of good value, but, it necessitates much resources (financial and manpower). There is some evidence suggesting that short-term video EEG (STVEEG) is useful, but its role in practice has yet to be evaluated. OBJECTIVE To assess the usefulness of STVEEG in the diagnosis of different paroxysmal disorders and classifying epilepsy if present. METHODS Thirty sex patients had STVEEG recordings (for 2h) during a 15 months period. RESULTS A diagnostic event was recorded in 21 of 36 (58.3%) within the first 2h of monitoring: PNES (n=11), epilepsy (n=5), and other paroxysmal disorders e.g. syncope, hemifacial spasm, movement disorder (n=5). CONCLUSIONS STVEEG is a useful diagnostic technique in diagnosis of different paroxysmal disorders and it can be used as a successful screening test for saving other resources like prolonged inpatient video EEG recording.

Epidemiology of nonfatal stroke and transient ischemic attack in Al-Kharga District, New Valley, Egypt.

Background Stroke is a medical emergency. Nonfatal stroke may cause permanent neurologic damage, complications, and disability. The aim of this study was to determine the epidemiology of nonfatal stroke in Al-Kharga District, New Valley, Egypt. Methods The total population (62,583) was screened via a door-to-door study by three neurology specialists and 15 female social workers for demographic data collection. All subjects with probable stroke were subjected to a full clinical examination, neuroimaging (computed tomography and/or magnetic resonance imaging of the brain), and laboratory investigations including blood sugar, lipid profile, serum uric acid, a complete blood count, blood urea, and serum creatinine. Stroke severity and outcome were assessed using the Scandinavian Stroke Scale and Barthel Index. Carotid Doppler, echocardiography, and thyroid function tests were done in selected cases. Results During the study period (June 1, 2005 to May 31, 2008), 351 subjects were diagnosed as having suffered a cerebrovascular stroke at some point during their lives, yielding a total lifetime prevalence of 5.6 per 1,000 population. Of these, 156 subjects were identified as having suffered a stroke during the year from January 1 to December 31, 2007, with an incidence rate of 2.5 per 1,000. Both prevalence and incidence rates were higher in urban (5.8 per 1,000 and 2.6 per 1,000, respectively) than rural communities (5.2 per 1,000 and 2.3 per 1,000), and were higher in males (6.1 per 1,000 and 2.7 per 1,000, respectively) than in females (5.1 per 1,000 and 2.3 per 1,000). Thrombotic stroke had the highest prevalence and incidence rates (4.2 per 1,000 and 1.7 per 1,000, respectively), whereas subarachnoid hemorrhage had the lowest prevalence and incidence rates (0.03 per 1,000 and 0.02 per 1,000). Conclusion The prevalence of cerebrovascular accident in Al-Kharga lies in the lower range of that in developing countries, and is similar to that in industrialized countries.
