Prevalence of primary headache disorders in Fayoum Governorate, Egypt

The relationship between myofascial trigger points sensitivity, cervical postural abnormality, and clinical tension-type headache parameters

BACKGROUND

Myofascial Trigger Points (MTrPs) play a significant role in the pathogenesis of Tension Type Headache (TTH). Abnormal cranio-cervical posture has been linked to various types of headaches. However, the correlation between MTrPs sensitivity, cervical postural alignment, and clinical measures of headache has not been extensively studied in patients with TTH.

OBJECTIVES

To investigate the relationship between MTrPs sensitivity in cervical and pericranial muscles, cervical postural abnormality, and clinical headache parameters in patients with TTH. Furthermore, to investigate the effect of sex on the examined variables and their association with headache type (episodic vs chronic TTH).

METHODS

A total of 72 patients with TTH of both sexes were enrolled in this study. Headache frequency and disability as clinical measures of headache, pressure pain threshold (PPT) of bilateral upper trapezius (UT) and suboccipital (SUB) muscles, cervical lordosis angle (CA), and anterior head translation (AHT) were measured.

RESULTS

Pericranial MTrPs sensitivity did not demonstrate any correlation with clinical headache parameters or cervical postural abnormality. However, there was a significant correlation between the frequency of headaches and the level of disability (r = 0.32, P < 0.05). In addition, episodic TTH was more prevalent in females who exhibited greater AHT and MTrPs sensitivity of both bilateral UT and right SUB muscles than males.

CONCLUSIONS

There was no correlation found between the frequency of headaches and the level of disability with measures of cervical posture alignment or MTrPs sensitivity in individuals with TTH.. Based on findings, Clinicians should consider sex differences when assessing patients with TTH.

Clinical characteristics and diagnostic delay in cluster headache in Egypt

BACKGROUND

Early diagnosis of CH is a cornerstone and it is important to detect causes leading to diagnostic delay. Limited published data exist regarding CH in Egypt, and with no data showing characteristics of CH or causes of diagnostic delay .

AIM

To investigate clinical characteristics, for CH and detect causes of diagnostic delay in Egypt.

METHODOLOGY

A cross-sectional study was conducted including all patients (age: 18-60 years) with primary headache disorders in Egypt with CH patients consecutively recruited over 1 year. Demographic and clinical characteristics as well as rate of diagnostic delay were collected.

RESULTS

This registry included 1187 patients with primary headaches over a year. CH accounted for 1.9% . The majority of CH patients were males (82%), and a mean age of 37.9 ± 10 years. The mean age of disease onset was 25 ± 8 years. Sixty-five percent had episodic CH, while 34.8% had chronic CH. Most of the patients (95.7%) had strictly unilateral pain (right side 52.2%, left side 43.5%). Autonomic features were rhinorrhea (91%), ptosis (87%), and lacrimation (78%). Migrainous features were found in 26% of patients. Bout duration of CH lasted on an average of 1-4 months. Time interval of diagnostic delay ranged from 0.5 to 29 years, with a mean diagnostic delay of 9.8 ± 7.9 years.

CONCLUSION

This study showed that CHs present 1.9% of primary headache disorders in Egypt, with males more affected than females. the incidence of smoking was higher among CH patients. Marked diagnostic delay was found which necessitate an action toward raising awareness.

The Prevalence and Clinical Phenotypes of Cluster Headache in Relation with Latitude

PURPOSE OF REVIEW

Previous studies have indicated a possible link between the prevalence of cluster headache (CH) and sunlight exposure. However, this theory has yet to be tested systemically. In this article, we aim to examine how latitude affects the prevalence and phenotypes of CH.

RECENT FINDINGS

To our knowledge, there is by far no article describing the effect of latitude on disease phenotype; thus, we performed a literature review. We noted positive effects of latitude on 1-year prevalence, the proportion of chronic CH, and the proportion of miosis and/or ptosis. Latitude may affect the phenotypic presentations of cluster headache, probably partially mediated via temperature and sunlight variations. Still, other factors, such as environmental exposure to smoking and the genetic difference between the Eastern and Western populations, may participate in the pathogenesis and clinical manifestations of CH.

The correlation between the frequent intake of dietary migraine triggers and increased clinical features of migraine (analytical cross-sectional study from Egypt)

Despite the high prevalence of primary headaches, the role of food in modifying clinical characteristics among migraine patients is often overlooked. The aim is to detect the correlation between adopting unhealthy dietary habits and migraine severity and identify foods that have a greater chance of triggering specific subtypes of migraine. The present study was a cross-sectional analytical study that was conducted at Kasralainy Hospital, Cairo University, headache clinic at Alexandria University Hospital, and Al-Azhar University Hospitals from January to June 2020. We included 124 patients fulfilling the ICHD-3 criteria for migraine. A full clinical profile for migraine headaches was reported using a headache sheet applied to the Al-Azhar University headache unit. A nutritionist obtained data collected about dietary habits using many reliable scales and questionnaires such as food frequently sheets questionnaire. Logistic regression and Pearson correlation coefficients have been used to identify foods that are more likely to be associated with increased clinical features of migraine. Our participants reported that the fried meat, fried chicken, processed meats, fava beans, falafel, aged cheese "Pottery salted cheese" and "Rummy cheese", salted-full fatty cheese "Damietta cheese", citrus fruits, tea, coffee, soft drinks, nuts, pickles, chocolate, canned foods, sauces, ice cream, smoked herring, in addition to the stored food in the refrigerator for many days were significantly associated with the diagnosis of chronic migraine CM compared to episodic migraine (EM). Margarine, pickles, and smoked herring were significantly associated with the diagnosis of migraine with aura (MA) compared to migraine without aura (MO). Adopting unhealthy eating habits was a more prevalent dietary consumption pattern among people with chronic migraines compared to those with episodic migraine.

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.

Frequency and risk factors for headache disability: A population-based cross-sectional study in Egypt

BACKGROUND

A headache is a very common condition that can have a significant impact on one's quality of life. It is one of the leading causes of years lived with disability worldwide. The objective of the study was to determine the prevalence of primary headache disability, its characteristics, risk factors and its impact on daily life.

MATERIALS AND METHODS

A cross-sectional study was conducted in Fayoum governorate. The sample size was 1909 participants. A multistage random sample technique was used to select adults aged above 18 years. A self-structured questionnaire solicited information on sociodemographic characteristics, headache characteristics, and the headache disability index. SPSS v 22.0 was used for data analysis.

RESULTS

Headaches caused complete disability in 19.5% of the study group, and 76.8% developed severe disability. Participants who reported that they had a headache more than once a week were; 44.5% had moderate pain and 40.2% had more intense pain. About 55% complained of attacks rather than continuous headache and were more likely to have a degree of complete disability, (P = 0.001). A statistically significant association was found between living in urban areas, working in professional occupations, complaining of severe headache in the form of an attack and seeking medical advice, with high scores of headache disability.

CONCLUSION

Headache is a condition that affects the entire population in a way that causes high levels of disability. Good management is necessary for the reduction of the adverse effects of headaches on the health of the population. This should focus on raising public awareness by means of education and on the provision of basic healthcare.

Migraine Management in Community Pharmacies: Knowledge, Attitude and Practice Patterns of Pharmacists in Saudi Arabia

In Saudi Arabia, community pharmacies offer healthcare services for different conditions. However, clarity of the competence of pharmacists in managing migraines is lacking. This study aimed to explore the current knowledge, attitude, and practice patterns of community pharmacists concerning migraine management in the northwestern part of Saudi Arabia. A cross-sectional study was carried out between June and September 2022 among 215 Saudi community pharmacists. Data analysis was performed by descriptive and inferential statistics using SPSS version 27. Most community pharmacists (87.9%) feel that migraine management is essential to their practice, and 83.3% suggest between one and five over-the-counter (OTC) migraine products daily. Among the study pharmacists, 83.7% feel migraine patients should try OTC before prescription medications. Only 9.3% of the community pharmacists do not believe that migraine is a neurological disorder. The medications most prescribed for migraine were triptans, representing 52.1% of prescriptions. There were significant differences between the gender of the pharmacists and their knowledge, attitude, and practice overall score (p-value = 0.04). Male pharmacists exhibited higher knowledge, attitude, and practice scores than female pharmacists. Although many community pharmacists acknowledge their expertise and involvement in managing migraines, there is a requirement for further education and training to enhance their capacity to offer complete care to migraine patients. Pharmacists should also consider non-pharmacological interventions and complementary therapies when treating migraine symptoms.

Perception of the general population towards migraine in Jeddah, Saudi Arabia

Background

Migraine is a chronic episodic neurological disorder characterized by a myriad of neurological symptoms including multi-phase attacks of headache, photophobia, phonophobia, and dizziness. To the best of our knowledge, there are no studies conducted about the public perception and attitudes towards migraine in Saudi Arabia. This study aims to determine the public perception and attitudes towards migraine in Jeddah, Saudi Arabia. This cross-sectional study was conducted during the period between September 2019 and January 2020 in various public places including malls in Jeddah, Saudi Arabia. The study utilized a 40-item self-administered survey questionnaire divided into two sections: demographic data of the participants and perception of participants towards migraine, which consisted of three parts—knowledge towards migraine, attitudes towards migraine, and the expected behavior of migraine patients.

Results

The total number of participants was 385. Three hundred and thirty-nine of the participants (88.1%) heard about migraine before. Relatives and friends are the main source of information for 213 participants (55.3%). In gender predominance, 137 (35.6%) believed that migraine affects both genders equally. Complications of migraine headache are not known for 240 participants (62.3%). The existence of medications or methods for treating migraine is not known for 195 (50.6%). The quality of life for patients with migraine is negatively affected according to 275 (70.9%). One hundred sixty-six participants (43.1%) believe that depression and anxiety are more common in migraineurs. Two hundred forty-four (63.4%) considered migraine to cause a huge psychological and social impact. Two hundred fifteen (55.8%) do not have the knowledge to deal with migraineurs.

Conclusion

The present study demonstrated a lack of knowledge in certain aspects of migraine in Jeddah, Saudi Arabia. This study will serve as a basis for developing a health educational program aiming to increase public awareness about migraine. It will also improve the understanding of society regarding migraine, which will subsequently improve the way they interact with migraineurs and understand their difficulties. In addition, finding a trusted source for information about different kinds of medical conditions including migraine is crucial in educating the community and providing them with the most recent and correct information.

Severe acute respiratory syndrome coronavirus 2 infection altered the factors associated with headache: evidence from a multicenter community-based case-control study

INTRODUCTION

Headache is one of the significant global public health concerns. Furthermore, it is a standard feature of patients with acute and postacute COVID-19.

OBJECTIVES

This study aimed to estimate and compare the prevalence of headaches among postacute COVID and non-COVID individuals and identify and contrast the risk factors between both groups.

METHODS

This was a multicenter case-control study. Individuals who had recovered from acute SARS-CoV-2 infection were considered "case", and those who never tested positive for COVID-19 were considered "control." Headaches were measured using the musculoskeletal subscale of the subjective health complaints scale. Multiple logistic regression analysis was used to identify the predictors of headaches.

RESULTS

A total of 878 individuals (439 cases) aged 38.30 ± 12.77 years (mean ± standard deviation) participated in this study. The prevalence of headaches was 26.2% among COVID-19 survivors; however, only 10.7% of unaffected participants reported headaches at the same time. Regression analyses suggested that the recovery duration from acute COVID-19 ≤ 90 days (adjusted odds ratio [AOR] = 2.03, CI = 1.13-3.65) was the only predictor of headache among postacute COVID-19 survivors. However, the female gender (AOR = 3.09, 95% CI = 1.51-6.32), members of a joint family (AOR = 1.99, 95% CI = 1.02-3.90), and city dwellers (AOR = 2.43, 95% CI = 0.94-6.25) were the predictor of headache among non-COVID participants.

CONCLUSION

This study found a higher prevalence of headaches among COVID-19 survivors. In addition, predictors of headache among cases and controls were unmatched, indicating heterogenous impact of COVID-19 on human health. The health care providers should be informed of the study's results when discussing better practices to mitigate the burden of headaches.

Primary headache disorders in epileptic adults

Background

Epilepsy and primary headache disorders are two relatively common neurological disorders and their relationship is still a matter of debate. We aimed to estimate the prevalence and clinical features of primary headache disorders in patients with epilepsy.

Methods

62 subjects aged ≥ 18 years were recruited from the hospital’s neurology outpatient clinic in the period from January to April 2018. The subjects were further divided into two equal groups, epileptics and non-epileptics. They underwent a semi-structured interview including the ILAE 2017 epilepsy classification and the ICHD III-beta criteria for headache. Patients' demographic data and clinical characteristics of epilepsy and headache and temporal relationships between them were assessed. Patients who experienced headaches were grouped based on the type of headaches and on whether their headaches occurred in the pre-ictal, post-ictal or inter-ictal period.

Results

Primary headache disorders were more common in epileptic group (61.3%) than the non-epileptic group (32.2%) (p = 0.021). The tension-type headache was the most common (45.2%) followed by migraine-type headache (12.9%) in the epileptic group. Post-ictal headache was the most common type (29%). Inter-ictal headaches were significantly related to "focal to bilateral tonic–clonic" seizures (p = 0.046). The prevalence of headache among patients on polytherapy (69.2%) was higher than that of patients on monotherapy (52.9%).

Conclusions

In this study, headache was more common in epileptic patients. TTH was the most represented type of headache in patients with epilepsy. Headache occurred in patients with epilepsy most frequently during the post-ictal period.

Characteristics of headache disorders, according to ICHD-III in an outpatient headache clinic in Sohag Governorate, Egypt

Background

Headache disorders are rated among the ten most disabling conditions around the world. The primary headache disorders are more common that of secondary headache. The third edition of the International Classification of Headache Disorders (ICHD-III) is considered as a helpful tool for classification and diagnosis of different headache disorders.

Methods

This is a cross-sectional study that included 500 patients who attended to the headache clinic, between May 2018 and April 2019. Arabic version of headache questionnaire was used to characterize headache, according to ICHD-III.

Results

Primary headache disorders were found in 89% (most of them is episodic in nature 76.2%), secondary headache disorders in about 10%, and painful cranial neuropathy was present in 0.8%. Primary headache associated with sexual activity was present in 1% of the total number of headache patients, and episodic cluster headache was found in 0.8%. Medication overuse headache (MOH) was the most frequent secondary headache with 2.8% of the total number of headache patients, and when overlaps with chronic migraine or chronic tension type of headache (TTH), the percent was 12.8% and 8.8% respectively. Male to female ratio was 1:3, 3:5, and 1:1 in primary headache, secondary headache, and painful cranial neuropathy respectively. Simple analgesia was the most common abortive therapy (44.8%) while the antidepressants were the most common preventive treatment (17%).

Conclusion

This study estimates the frequency and characterizes different headache disorders, according to ICHD-III in an outpatient headache clinic at Sohag Governorate, Egypt.

Diffusion tensor magnetic resonance imaging: is it valuable in the detection of brain microstructural changes in patients having migraine without aura?

Purpose

The aim of this study is to assess the diagnostic value of diffusion tensor magnetic resonance imaging (MRI) in the detection of brain microstructural changes in patients having migraine without aura.

Material and methods

Our prospective study included 33 patients having migraine without aura and 15 volunteers with matched age and sex, who underwent brain MRI with diffusion tensor imaging (DTI). The fractional anisotropy (FA) and mean diffusivity (MD) of selected grey and white matter regions on both sides were measured and correlated with the neurological clinical examination.

Results

Significant differences were detected in MD values in the thalamus, globus pallidus, and hippocampus head on the right side of patients versus controls. Also, significant differences of the FA values were detected in the thalamus, globus pallidus, and hippocampus head on the right side of patients versus controls. Regarding the FA values of the same regions on the left side, a significant difference in the FA value was detected only in the hippocampus head. There was a statistically significant difference in the FA values on both sides of the white matter of the frontal lobes, posterior limbs of the internal capsules, and cerebellar hemispheres in patients compared to controls. There was a statistically significant difference in MD values in the white matter of both frontal lobes, posterior limb of the right internal capsule, and both cerebellar hemispheres in patients compared to controls.

Conclusions

DTI can detect microstructural changes of the grey and white matter in patients having migraine without aura that could not be detected by conventional MRI.

Dilemma of migraine diagnosis and management among non-neurologists

Background

Migraine is a common and debilitating disorder however there is a wide gap in its diagnosis and management. Many migraine patients present to non-neurologists, so it is of utmost importance that non neurologists become well oriented with the diagnostic criteria and different lines of management. The aim of the study was to assess the knowledge and attitude of non-neurologists towards migraine.

Results

About 45% of physicians in our study refer migraine patients to non-neurologists, only 20.96% are aware of both classic and novel treatments, 43% had poor knowledge of migraine symptoms and management, 32.34% recommended using medical tailored programs to increase the awareness of non-neurologists regarding migraine.

Conclusions

There is a wide gap of knowledge concerning migraine among non-neurologists.

Complementary and alternative therapies for tension-type headache: A protocol for systematic review and network meta-analysis

BACKGROUND

Tension-type headache (TTH) is the most common form of primary headache with high prevalence, which affects the quantity of life seriously. The pharmacological treatment of TTH is not the most effective. Meanwhile, complementary therapies and alternative therapies play an essential role in the treatment of TTH, and there is an absence of comparison between various interventions. Therefore, we propose the network meta-analysis protocol to compare the efficacy and safety of various complementary therapies and alternative therapies for TTH.

METHODS

From the beginning to February 2021, we will search the database to collect randomized controlled trials of complementary and alternative therapies for TTH. Two researchers will be responsible for screening retrieve documents, extracting data. The risk of bias will be assessed based on the Cochrane bias risk tool. We will use STATA16.0 and WinBUGS1.4.3 for paired meta-analysis and Bayesian network meta-analysis. The quality of evidence will be assessed using the grading of recommendations assessment development and evaluation.

RESULTS

This study will compare and rank the efficacy and safety of various complementary and alternative treatments for TTH.

CONCLUSIONS

This study will provide more extensive evidence for the complementary and alternative therapies of TTH. We expect to assist clinicians and patients in choosing the optimum treatment.

The Epidemiology of Migraine Headache in Arab Countries: A Systematic Review

Background

Recurring migraine disorders are a common medical problem, standing among the top causes of disability and sufferings. This study aimed to evaluate epidemiological evidence to report updated estimates on prevalence, risk factors, and associated comorbidities of migraine headache in the Arab countries. Design and Setting. A systematic review was conducted at the College of Public Health and Health Informatics, Riyadh, Saudi Arabia.

Methods

A systematic search in electronic databases, such as PubMed and Embase, as well as manual searches with cross-referencing was performed from 1990 up to 2019. Overall, 23 included papers were rated independently by two reviewers. Studies were eligible for inclusion only if they investigated migraine headache epidemiology in any Arab country and were published in English.

Results

Migraine prevalence among the general population ranged between 2.6% and 32%. The estimated prevalence of migraine headache among medical university students ranged between 12.2% and 27.9% and between 7.1% and 13.7% in schoolchildren (6 to 18 years). Females were found more likely to have migraine than males. The duration of migraine attacks became shorter with increasing age, while chronic (daily) migraine showed increasing prevalence with age. The most commonly reported comorbidities with migraine included anxiety, hypertension, irritable bowel syndrome, and depression. Most common headache-triggering factors included stress, fatigue, sleep disturbances, prolonged exposure to excessive sunlight or heat, and hunger.

Conclusion

The prevalence and risk factors of migraine headache in Arab countries are comparable to reports from western countries. Longitudinal studies are still needed to investigate the prognosis and predictors of chronicity in the arab countries.

Cluster Headache in Kuwait: A Hospital-Based Study

Background: Cluster headache (CH) is a relatively uncommon primary headache disorder. Few studies in our region described CH. We aimed to study demographics, clinical characteristics and treatment modalities of CH patients referred to Headache Clinic in Kuwait. Materials and Methods: This cross-sectional study included all CH patients who are referred to headache clinic. The diagnosis of CH based on the CH diagnostic criteria of the Headache Classification Committee of the IHS, 3rd edition (beta version) (ICHD-3-beta). The demographics, clinical characteristics and treatment modalities of CH patients were recorded. Results: Forty six patients were diagnosed with CH which constituted 1.7% of all headache patients and 0.1% of all visits to Neurology clinic. Male:Female ratio was 15.3:1. Mean age was 40.1 ± 10.7 years and mean age at onset was 29 years (20-49). Family history was positive in 6.5%. Smoking was seen in 63.0% of patients while 6.5 % reported alcohol intake. CH was episodic in 84.4% and chronic in 15.2%. Seasonal predilection was seen in all patients; the most frequent season was Autumn 47.8%. The mean duration of the cluster bouts was 6 weeks (2-12 weeks). The mean duration of the attack was 60 min (15-180 min). Number of attacks per day ranged from 2 to 10 attacks with a mean of 5 attacks/day. The median of attack severity by Visual Analog Scale (VAS) was 8.5 (7-10). The time taken to diagnose the patients ranged from <1 year to 12 years with a mean of 4 years. Chronic CH have a statically significant relation with smoking (P = 0.036), older age (P = 0.027), and longer time taken to diagnosis (P = 0.026) compared to episodic CH. Conclusion: Our results reported that there is higher proportion of males compared to females and less positive family history. Smoking was a significant risk factor for chronicity in addition to advanced age, higher age at disease onset and a longer time taken till diagnosis.

Increased risk of sleep apnoea among primary headache disorders: a nationwide population-based longitudinal study

Background

Primary headache disorders (PHDs) are associated with sleep problems. It is suggested that headache and sleep disorder share anatomical and physiological characteristics. We hypothesised that patients with PHDs were exposed to a great risk for developing sleep apnoea (SA).

Methods

In this retrospective longitudinal study, the data obtained from the Longitudinal Health Insurance Database in Taiwan were analysed. The study included 1346 patients with PHDs who were initially diagnosed and 5348 patients who were randomly selected and age/sex matched with the study group as controls. PHDs, SA, comorbidities and other confounding factors were defined based on International Classification of Diseases, Ninth Revision, Clinical Modification. Cox proportional hazards regressions were employed to examine adjusted HRs after adjusting with confounding factors.

Results

Our data revealed that patients with PHDs had a higher risk (HR 2.17, 95% CI 1.259 to 3.739, p<0.05) to develop SA compared with matched cohorts, whereas patients with migraine exhibited a high risk (HR 2.553, 95% CI 1.460 to 4.395, p<0.01). The results showed that patients with PHDs aged 18–44 exhibited highest risk of developing SA. In addition, males with PHDs exhibited an HR 3.159 (95% CI 1.479 to 6.749, p<0.01) for developing SA, respectively. The impact of PHDs on SA risk was progressively increased by various follow-up time intervals.

Conclusion

Our results suggest that PHDs are linked to an increased risk for SA with sex-dependent and time-dependent characteristics.

Is there a misuse of computed tomography in the diagnostic workup of headache? A retrospective record-based study in secondary health-care facility in Saudi Arabia

Introduction

Headache disorders are one of the most prevalent global public-health problems that require placing high demand on health-care Services. Since it is one of the most frequent complaints in clinical practice worldwide, it causes a considerable burden in terms of the social cost. The study aimed to give a guide for the decision on the utilization of computed tomography (CT) in the diagnostic workup and identify if patients require neurological imaging (CT) for proper diagnosis or not.

Materials and Methods

The study was carried out in the Radiology Department in King Khalid Hospital, Al Kharj, Saudi Arabia from October 15, 2016, to February 15, 2017. A retrospective record-based study conducted using the documented CT reports in the files of patients whom were referred to the radiology department complaining of any type of a headache.

Results

The data included 210 patients 51% were males and 49% were females. The patients were distributed into age groups; the mean age was 38.46 standard deviation ± 13.56. Among Saudi population, the etiology of headache was varying; the most prevalent type of headache was tension headache 25.71% of the total headache patients followed by cluster 25.24% and the migraine with the lowest proportionality. The majority of the patients' headache pain was mild 60%. Moreover, the CT reports for most of the patients were normal. Spearman Correlation test was used to see if there is a significance in using the CT for any patient who comes with symptoms including headache, and the results have shown that there is no association and clinical significance in using the CT for patients with headache without suspecting other clinical condition (P = 0.177).

Conclusion

Headache disorders must be on the public-health agenda. Tension, migraine, and cluster-type headaches represent the majority of primary headaches. Statistically no significance or need to obtain CT if there are no life-threatening conditions expected or trauma presented.

Prevalence of Primary Headache Disorders in Kuwait

Background: Only an insignificant quantum of data exists on the prevalence of primary headaches among those living in Kuwait. We aimed to determine the prevalence of primary headaches among the Kuwaiti population. Methods: This community-based study included Kuwaiti population aged 18-65 years. Using systematic random sampling, data was collected by the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation questionnaire. Responses to the diagnostic questions were transformed into diagnoses algorithmically to confirm the diagnosis of primary headache. Results: A total of 15,523 patients were identified of whom 9,527 (61%) were diagnosed with primary headache disorder; a female predominance of 62.2% was observed. The mean age was 34.84 ± 10.19. Tension-type headache (TTH) was the most prevalent at 29% followed by episodic migraine (23.11%), chronic migraine (5.4%), and medication overuse headache (2.4%). Primary headache prevalence declined steadily from 71% in those aged 18-30 years to 23% in those over 50 (p < 0. 037). The female:male ratio was 1.7:1. Frequency and severity of primary headache were correlated significantly with lost work days (r = 0.611, p < 0.001 and r = 0.102, p = 0.001, respectively). Conclusions. In Kuwait, primary headache disorder is more frequent in young adults and females. TTH followed by episodic migraine were the more prevalent types of headache. Higher frequency and severe headaches were associated with increasing social and work-related burden.

Development and validation of an Arabic-language headache questionnaire for population-based surveys

Background

The reported prevalence of headache disorders in Arab regions varies considerably between countries. This may be due to a lack of standardized survey instruments that capture the prevalence.

Purpose of the study

Our goal was to construct and validate a structured headache questionnaire for Arabic-speaking headache patients to be used as an epidemiological survey instrument.

Methods

We developed a culturally adapted interviewer-administered questionnaire in Arabic language comprising two sets of questions. The first set included personal and sociodemographic data together with a screening question regarding the presence of headaches over the last year. The second set was designed to define the type and pattern of headaches according to the International Classification of Headache Disorders criteria (for subjects with “yes” answers on the screening question). Validation process took place in two phases through probability random sampling selected from 1,221 headache subjects collected in an epidemiological survey 3 (n=70) and 6 months (n=232) later. A detailed assessment of patients’ headaches was performed by neurologists (blinded from the questionnaire diagnosis) who clinically assessed the patients’ headache.

Results

The validity of the questionnaire was tested in 232 subjects with a mean age of 41.2±10.9 years, 72.8% of whom were females. The mean time to complete the questionnaire was 8.4±1.7 minutes. The intraclass correlation coefficient was 0.903 (95% confidence interval: 0.875–0.925), the Cronbach κ coefficient was 0.775 (95% confidence interval: 0.682–0.837), and the percentage of agreement was 84.5%.

Conclusion

Our results support the use of this comprehensive questionnaire as a valid tool for headache assessment among Arabic-speaking patients.

Psychiatric Comorbidities and Environmental Triggers in Patients with Chronic Daily Headache: A Lifestyle Study

Objective: Patients with chronic daily headache (CDH) suffer from several significant psychiatric comorbidities and have unhealthy lifestyle. We aimed at studying psychiatric comorbidities, environmental triggers, lifestyle factors, and intensity of CDH in patients referred by the department of neurology from 2011 to 2014. Method: Through medical and psychiatric interviews and using 0 to 10 visual analogue scale (VAS), we assessed patients with CDH, using a checklist, to elicit psychiatric comorbidities, intensity of CDH, environmental factors, and lifestyle derangement. Results: We interviewed 413 (age 16-80 years, mean 40 +/- 14.0) out of 548 patients; 312 (75.5%) were married, and 282 (68.1%) were female. Environmental triggers (374, 90.6%) were the most common cause of CDH, while 214 (51.8%) had no compliance to recommended nutrition. Exercise avoidance (201, 48.7%) was the less prevalent lifestyle factor. Of the patients, 372 (90.1%) were stressed and 162 (39.2%) had obsessive-compulsive disorder (OCD), which were the most and less prevalent psychiatric comorbidities, respectively. Intensity of pain was moderate to severe (mean score = 7.1+/- 1.9), while females reported higher VAS scores (p<0.02). Patients with previous history of psychotherapy reported higher score of VAS (p<0.001). Those patients living with a person suffering from head pain reported more VAS score (p<0.003). Conclusion: Notable psychiatric comorbidities were found in patients with CDH, many of which are modifiable such as environmental triggers and unhealthy lifestyle. In heavily populated cities, these factors may double the burden of the CDH by precipitating new or exacerbating previous psychiatric comorbidities. We, thus, suggest conducting more studies on this subject.

Repetitive transcranial magnetic stimulation versus botulinum toxin injection in chronic migraine prophylaxis: a pilot randomized trial

BACKGROUND

Chronic migraine is a prevalent disabling disease, with major health-related burden and poor quality of life. Long-term use of preventive medications carries risk of side effects.

OBJECTIVES

The aim of this study was to compare repetitive transcranial magnetic stimulation (rTMS) to botulinum toxin-A (BTX-A) injection as preventive therapies for chronic migraine.

METHODS

A pilot, randomized study was conducted on a small-scale sample of 29 Egyptian patients with chronic migraine, recruited from Kasr Al-Aini teaching hospital outpatient clinic and diagnosed according to ICHD-III (beta version). Patients were randomly assigned into two groups; 15 patients received BTX-A injection following the Phase III Research Evaluating Migraine Prophylaxis Therapy injection paradigm and 14 patients were subjected to 12 rTMS sessions delivered at high frequency (10 Hz) over the left motor cortex (MC, M1). All the patients were requested to have their 1-month headache calendar, and they were subjected to a baseline 25-item (beta version) Henry Ford Hospital Headache Disability Inventory (HDI), Headache Impact Test (HIT-6), and visual analogue scale assessment of headache intensity. The primary efficacy measures were headache frequency and severity; secondary measures were 25-item HDI, HIT-6, and number of acute medications. Follow-up visits were scheduled at weeks 4, 6, 8, 10, and 12 after baseline visit.

RESULTS

A reduction in all outcome measures was achieved in both the groups. However, this improvement was more sustained in the BTX-A group, and both the therapies were well tolerated.

CONCLUSION

BTX-A injection and rTMS have favorable efficacy and safety profiles in chronic migraineurs. rTMS is of comparable efficacy to BTX-A injection in chronic migraine therapy, but with less sustained effect.
