11. Cervicogenic headache and occipital neuralgia.

INTRODUCTION: Cervicogenic headache (CEH) and occipital neuralgia (ON) are headaches originating in the occiput and that radiate to the vertex. Because of the intimate relationship between structures based in the occiput and those in the upper cervical region, there is significant overlap between the presentation of CEH and ON. Diagnosis starts with a headache history to assess for diagnostic criteria formulated by the International Headache Society. Physical examination evaluates range of motion of the neck and the presence of tender areas or pressure points. METHODS: The literature for the diagnosis and treatment of CEH and ON was searched from 2015 through August 2022, retrieved, and summarized. RESULTS: Conservative treatment includes pain education and self-care, analgesic medication, physical therapy (such as reducing secondary muscle tension and improving posture), the use of TENS (transcutaneous electrical nerve stimulation), or a combination of the aforementioned treatments. Injection at various anatomical locations with local anesthetic with or without corticosteroids can provide pain relief for a short period. Deep cervical plexus block can result in improved pain for less than 6 months. In both CEH and ON, an occipital nerve block can provide important diagnostic information and improve pain in some patients, with PRF providing greater long-term pain control. Radiofrequency ablation of the cervical facet joints can result in improvement for over 1 year. Occipital nerve stimulation (ONS) should be considered for the treatment of refractory ON. CONCLUSION: The treatment of CEH preferentially consists of radiofrequency treatment of the facet joints, while for ON, pulsed radiofrequency of the occipital nerves is indicated. For refractory cases, ONS may be considered.

Eicosapentaenoic acid versus placebo as adjunctive therapy in chronic migraine: A randomized controlled trial.

OBJECTIVE: This study was conducted to assess the efficacy of daily 2000 mg eicosapentaenoic acid (EPA) supplementation in individuals with chronic migraine. BACKGROUND: Chronic migraine is characterized by a minimum of 15 headache days/month, necessitating a focus on preventive treatment strategies. EPA, a polyunsaturated fatty acid recognized for its anti-inflammatory properties, is examined for its potential effectiveness in chronic migraine management. METHODS: A randomized, blinded, placebo-controlled trial of eligible participants with a confirmed diagnosis of chronic migraine were enrolled. The intervention group received 1000 mg of EPA twice daily for 8 weeks, while the control group received two placebo softgels. Symptoms were recorded at 4 and 8 weeks. The primary outcome was assessed using the Headache Impact Test-6 to evaluate changes in patients. Secondary outcomes encompassed migraine headache days, headache severity measured via a visual analog scale, and the number of consumed painkillers. Descriptive analyses were reported in mean (± standard deviation [SD]). RESULTS: A total of 60 patients were included in the study and finally, 56 patients completed the study according to the protocol, including 47 (84%) females. The data comparison at baseline did not show any significant difference between the two groups except in the number of patients using valproic acid as prophylaxis (21 patients in the EPA group, and 13 in the placebo group; p = 0.037). The results showed after 8 weeks, a mean (SD) difference of Headache Impact Test-6 in the EPA and placebo groups was -6.96 (3.34) and -4.43 (5.24), respectively (p = 0.084). Regarding migraine headache days, participants reported a mean (SD) -9.76 (4.15) and -4.60 (4.87) decline in days with headache, respectively (p < 0.001). The number of attacks per month after 8 weeks was 3.0 (95% confidence interval [CI] 2.0-4.0) and 4.0 (95% CI 3.0-6.0), respectively (p < 0.001). Regarding severity, there was no significant difference between the two groups (mean [SD] difference: -0.76 [1.13] and -0.73 [1.04], respectively; p = 0.906). In terms of adverse events, two patients in the EPA group reported intolerable nausea and vomiting, and one patient in the placebo group reported dizziness. CONCLUSIONS: This study's findings support the potential of a daily 2000 mg EPA as a prophylactic pharmacotherapy in chronic migraine management, specifically in mitigating migraine attacks, migraine headache days, and overall quality of life.

Spontaneous intracranial hypotension mimicking iatrogenic spinal cerebrospinal fluid leaks.

OBJECTIVE: To raise awareness that patients with persistent post-dural puncture headache should be considered for evaluation of spontaneous cerebrospinal fluid (CSF) leak. BACKGROUND: Spontaneous intracranial hypotension (SIH) due to a spinal CSF leak may occur following more-or-less trivial traumatic events. We report our experience with spontaneous spinal CSF leaks that occur following percutaneous or open spine procedures, a potential source of diagnostic confusion. METHODS: In a retrospective cohort study, using a prospectively maintained database of patients with SIH, we identified all new patients evaluated between January 1, 2022, and June 30, 2023, who were referred for evaluation of an iatrogenic spinal CSF leak but were found to have a spontaneous spinal CSF leak. RESULTS: Nine (4%) of the 248 patients with SIH were originally referred for evaluation of an iatrogenic spinal CSF leak. The spinal procedures included epidural steroid injections, laminectomies, epidural anesthesia, and lumbar puncture. Brain magnetic resonance imaging (MRI) showed changes in intracranial hypotension in seven of the nine patients (78%). The spontaneous CSF leak was found to be at least five levels removed from the spinal procedure in all patients. CONCLUSIONS: A spontaneous spinal CSF leak should be suspected in patients with recalcitrant orthostatic headaches following a spinal procedure, even if symptoms of the leak occur within hours of the spinal procedure and especially if brain MRI is abnormal.

Consensus guidelines for the management of pineal region tumours for low- and middle-income countries.

Pineal region tumours are rare and mainly arise at a younger age. They can be categorized into various types: germ cell tumours (GCT), pineal parenchymal tumours (PPT), meningiomas, gliomas, pineoblastoma, pineal parenchymal tumours of intermediate differentiation, papillary tumours of the pineal region, and SMARCB1- mutant desmoplastic myxoid tumour. Within GCT, germinomas are the most prevalent, comprising the majority of tumours in this region, while nongerminomatous GCTs are also present. In rare instances, metastases from other sites may manifest. These tumours often lead to obstructive hydrocephalus and commonly exhibit symptoms related to mass effect, including headache, nausea, vomiting, and impaired gait stability. Different subtypes of pineal region tumours exhibit distinct radiological characteristics, thus imaging remains the primary diagnostic tool. Histologic diagnosis necessitates biopsy, unless in cases of germ cell tumours, particularly germinomas, which can be identified through elevated levels of tumour markers like alpha-fetoprotein (AFP) and human chorionic gonadotropin (HCG) in both cerebrospinal fluid (CSF) and serum. While benign tumours might be effectively treated with radical resection alone, malignant tumours demand additional chemotherapy and radiotherapy following surgical removal.

The burden of headache disorders in the adult population of Mongolia: estimates, and a health-care needs assessment, from a cross-sectional population-based study.

BACKGROUND: Having previously shown headache disorders to be prevalent in Mongolia, here we elaborate on headache as a public-health concern in this country, reporting symptom burden and headache-attributed impaired participation at individual and societal levels, and conducting a health-care needs assessment. METHODS: The study followed the standardized methodology developed by the Global Campaign against Headache, generating a representative general-population sample through multi-level randomized cluster sampling. Participants aged 18-65 years were interviewed at unannounced household visits by interviewers administering the HARDSHIP questionnaire. Symptom burden was established through questions on frequency, duration and intensity of headache, with proportion of time in ictal state calculated from frequency and duration. Individual impaired participation was established through the HALT questionnaire, enquiring into lost time from paid and household work and from leisure activities. Symptom burden and impaired participation yesterday were also assessed in those reporting headache yesterday. Population-level estimates were derived by factoring in prevalence. RESULTS: The total sample included 2,043 participants. Those reporting any headache in the last year (n = 1,351) spent, on average, 9.7% of all their time with headache, losing 1.3 workdays and 2.4 household days/3 months. These losses were considerably higher among those with probable medication-overuse headache (37.5%, 3.5 workdays, 6.7 household days) or other headache on ≥ 15 days/month (H15+) (21.9%, 2.4 workdays, 5.1 household days). At population-level (including those with and without headache), 6.2-7.4% of all time was spent with headache, 3.1% with H15+; 0.8 workdays and 1.4 household days/person/3 months were lost to headache, 0.3 workdays and 0.6 household days to migraine (the biggest contributor of all headache types). Our needs assessment estimated that one third (33.2%) of the adult population of Mongolia have headache (mostly migraine or H15+) likely to benefit from health care. CONCLUSION: This first population-based study on headache burden in Mongolia shows high levels of individual and societal burden, with H15 + the cause of greater burden at population level than migraine and TTH combined. Migraine, however, has the biggest impact on the nation's productivity. From a purely economic perspective, Mongolia, with limited health resources, would probably be best served by focusing on mitigating migraine-attributed burden.

The association between dietary antioxidant quality score and intensity and frequency of migraine headaches among women: a cross-sectional study.

BACKGROUND: Migraine is an episodic disorder and a frequent form of headache. An impaired balance between free radical production and an impaired antioxidant defense system leading to oxidative damage may play a major role in migraine etiology. We sought to investigate whether dietary antioxidant quality score (DAQS) is associated with migraine intensity and frequency among women suffering from migraine. METHODS: This cross-sectional study was conducted on 265 women. The data related to anthropometric measures and dietary intake were collected. DAQS score was calculated based on FFQ (food frequency questionnaire) vs. the reference daily intake (RDI) quantity. To measure migraine intensity, the migraine disability assessment questionnaire (MIDAS) and visual analog scale (VAS) were used. The frequency of headaches was defined as the days the participants had headaches in the last month and a 30-day headache diary was used. RESULTS: The results of the study demonstrated that VAS, MIDAS, and frequency of headaches were reduced significantly from the low DAQS (poor quality of antioxidants) to high DAQS (high quality of antioxidants) after adjusting covariates. Also, multinomial regression showed there was an inverse association between higher DAQS and the frequency of headaches. In the adjusted model, subjects with the higher DAQS were 69% less likely to have moderate migraine disability, compared with those with the lower DAQS. Linear regression showed, there was an inverse association between vitamin C intake and the grades of pain severity.َAlso in a crude model, a negative association was found between vitamin E and the frequency of headaches. CONCLUSION: In conclusion, Participants with higher DAQS had lower migraine intensity and headache frequency. In addition, the consumption of vitamin C may potentially associate with decreasing the severity of headaches. Dietary antioxidants should be monitored closely in individuals suffering from migraine.

Oral and dental health status in patients with chronic headache.

INTRODUCTION: Headache is an illness with high prevalence and adverse effects on quality of life. As oral or dental problems such as pain can trigger or aggravate it, we aimed to investigate and compare oral and dental health status in patients affected with chronic headaches and healthy individuals. METHODS: The present case-control study included 60 patients with chronic headaches (case) and 60 healthy individuals (control) in Rasht, Iran. The demographic characteristics and clinical examinations, including decayed/missing/filled teeth (DMF-T) and community periodontal index of treatment needs (CPITN) indices, as well as bruxism, frequency of tooth brushing and flossing, and maxillary and mandibular tooth wear were recorded in a checklist. Data analysis was performed using the IBM SPSS version 28 at a significance level of 0.05. RESULTS: The case group consisted of 25 men (41.7%) and 35 women (58.3%) with an average age of 32.55 ± 6.62 years, while the control group had 27 men (45%) and 33 women (55%) with an average age of 30.95 ± 6.33 years. The study groups were not significantly different in bruxism, frequency of tooth brushing and flossing, DMFT, CPTIN, and maxillary and mandibular tooth wear. CONCLUSION: It seems that chronic headaches do not significantly affect the oral and dental health of the sufferers. Moreover, it appears that these patients are well aware of the role of oral and dental hygiene in triggering or aggravating the episodes of headaches.

Evaluating the Frequency of Osmophobia in Tension-Type Headache: A Comparative Study on Migraine.

Introduction Osmophobia is hypersensitivity to certain odors. Although osmophobia is a symptom related to migraine, it is also reported in tension-type headache (TTH). Osmophobia is recommended for inclusion in the migraine diagnostic criteria because it increases sensitivity and shows absolute specificity. However, there is no evidence of the association between TTH and osmophobia. This study aimed to evaluate the prevalence and clinical characteristics of osmophobia in a cohort of migraine and TTH patients. Methods For the current analysis, patients who met the inclusion criteria among patients diagnosed with migraine and TTH according to the International Classification of Headache Disorders III criteria in the neurology outpatient clinics of Ankara City Hospital and Akyazi State Hospital were selected retrospectively. A total of 214 patients (129 with migraine and 85 with TTH) were included in the study. Patients' characteristics, visual analog scale (VAS) pain scores, and Migraine Disability Assessment Scale (MIDAS) scores were recorded. Osmophobia characteristics in migraine and TTH patients were compared along with clinical parameters between the groups and within the groups. Results Osmophobia was found in 68% of migraine patients. The most common type of smell that migraine patients experienced was the scent of perfume. A total of 31.3% of the patients with TTH had osmophobia. While the most irritating odorant in migraine patients was perfume (32%), in TTH patients, it was the smell of food (10.5%). There were no significant differences between osmophobia, and age, education level, disease duration, pain frequency, attack duration, or VAS score in both migraine patients and TTH patients. There was also no significant difference between migraine patients with (2.42) and without (2.33) osmophobia in terms of the MIDAS score. Discussion Our study indicates that osmophobia observed in migraine is valuable in differential diagnosis. However, it can be significantly identified in TTH patients. It should be used together with other supporting criteria in differential diagnosis. It would also be useful to question the characteristics of osmophobia in more detail in the anamnesis.

Treatment of migraine with aura with osteopathic manipulative treatment: a case report with renewed perspectives.

Migraines make up a significant number of office visits every year, yet their pathophysiology and etiology remain largely elusive. This case report presents a 33-year-old patient who originally presented to the emergency department (ED) as a stroke alert and was later determined to have migraine with aura. The patient experienced an acute onset of headache, dizziness, and new-onset expressive aphasia. Before administration of a migraine cocktail, osteopathic manipulative treatment (OMT) was performed and was able to fully resolve all of her symptoms. In an effort to explain the outcomes in this case, a review of the current literature was performed, which provides an interesting perspective on the interplay of the musculoskeletal system and neuroanatomy. The literature establishes that somatic dysfunctions in the cervical vertebrae and trapezius may play a role in migraines and provide rationale for the use of OMT.

Effectiveness and safety of monthly versus quarterly fremanezumab for migraine prevention: An Italian, multicenter, real-life study.

BACKGROUND AND PURPOSE: Fremanezumab, a monoclonal antibody targeting the calcitonin gene-related peptide for migraine prevention, is available in monthly (225 mg) and quarterly (675 mg) doses. Previous studies showed efficacy and safety for both regimens, but a real-life comparison is lacking. This study aimed to compare the effectiveness and safety of monthly and quarterly fremanezumab in a real-life setting. METHODS: This Italian, prospective, multicenter study enrolled 95 migraine patients. During a 3-month treatment period, patients received either monthly or quarterly fremanezumab (49 monthly, 46 quarterly). A 6-month treatment period involved 79 patients (43 monthly, 36 quarterly). Monthly headache (MHD) and migraine days (MMD), number of days (AMD) and pills (AMP) of acute medication intake, and Headache Impact Test (HIT-6), Migraine Disability Assessment (MIDAS) test, and Numeric Rating Scale (NRS) scores were recorded at baseline and after 3 and 6 months of treatment. Adverse events (AEs), responder rates, and medication overuse were also investigated. RESULTS: Both monthly and quarterly treatments led to significant reductions in MMD, MHD, AMP, AMD, HIT-6, MIDAS, and NRS scores after 3 and 6 months. The monthly regimen exhibited a slightly greater reduction in MMD and MHD after the first quarter, with no significant difference observed after 6 months. The most common AE was transient injection-site reaction, without between-group differences. Responder rates and resolution of medication overuse did not significantly differ between the groups. CONCLUSIONS: Both monthly and quarterly regimens were effective and safe, with a tendency for an advantage of the monthly regimen only in the first quarter of treatment.

Sex and age-related patterns in pediatric primary headaches: observations from an outpatient headache clinic.

Background: Age reportedly affects headache prevalence differently in boys and girls. However, little empirical data exists regarding pediatric headache prevalence and headache-related burden in children and adolescents according to age and sex. In the present study, we considered age and sex while evaluating the distribution, characteristics, and impairment of primary headache disorders at a pediatric headache center in Germany. Methods: Medical records of children and adolescents attending the headache clinic of the Interdisciplinary Pain Center of the Carl Gustav Carus University Hospital in Dresden during the period 2015-2022 were retrospectively grouped and analyzed depending on age (< or ≥14 years) and sex. Results: The study population consisted of 652 children and adolescents, aged between 3 and 18 years. Almost two-thirds of the patients (≈60%) were females, and almost two-thirds of these females (58%) were ≥14 years of age. Generally, the most prevalent headache diagnoses as defined by the International Classification of Headache Disorders 3rd edition were episodic migraine without aura and the combination of tension-type headache and episodic migraine with or without aura i.e., mixed-type headache (each ≈27%). In the younger group (<14 years), the mixed-type headache was the most prevalent in girls (28.6%), whereas, for boys, episodic migraine without aura was the most prevalent headache diagnosis (47.4%). In the older group (≥14 years), the mixed-type headache continued to be the most prevalent for girls (30%), and it became the most prevalent for boys (26.3%). Before the age of 14, about 16% of children were severely affected by their headaches. After the age of 14, this proportion increased to roughly one-third (33%) of adolescents, driven mainly by teenage girls (26%) who were severely affected by their headaches. Furthermore, the prevalence of comorbidities was significantly higher among girls (67%), particularly in the adolescent group (74%). Conclusions: Our data shows that headache disorders in a specialized pediatric clinic impose a significant burden, especially among teenage girls indicating high therapy needs. Enhancing awareness of early diagnosis and preventive care is crucial to mitigate the development of chronic headaches, and mitigate their adverse effects on life quality and educational capability.

The impact of fear of attacks on pain-related disability in cluster headache: Insights from the fear avoidance model.

OBJECTIVE: This study utilized the theoretical framework of the "fear avoidance model" (FAM) and investigated the role of fear of attack in pain-related disability. To this end, a measurement specific to cluster headache (CH) was used to investigate whether fear of attacks, alongside attack frequency, is a significant predictor of pain-related disability in CH. BACKGROUND: Cluster headache substantially impacts daily functioning, yet empirical research exploring specific contributing factors is limited. METHODS: A cross-sectional online survey was undertaken in patients with CH, gathering sociodemographic, clinical data, and responses on the Cluster Headache Scale and the Depression, Anxiety and Stress Scale. RESULTS: Analysis of data from 640 patients (chronic CH: 287/640 [44.8%]; female: 264/640 [41.3%]; male: 373/640 [58.3%]; gender diverse: three of 640 [0.5%]; age range: 18-86 years; mean [standard deviation] Cluster Headache Scales subscale disability score: 36.9 [9.8]; out of 869 respondents) revealed that both attack frequency and fear of attacks significantly predicted pain-related disability (p < 0.001, percentage of variance explained: R2 = 0.24). More variance was explained by fear of attacks (R2 = 0.22) than by attack frequency (R2 = 0.02). This relationship remained significant even when controlling for depression and anxiety, which were also identified as independent predictors of pain-related disability (p < 0.001, R2 = 0.44). CONCLUSION: This study emphasizes the relevance of psychological factors in CH-related disability. Fear of attacks was found to be an independent predictor, while attack frequency was of minor relevance. Empirical investigation of the FAM in CH could improve the understanding of the mechanisms underlying disability and contribute to the development of CH-specific interventions.

Assessing the effects of spontaneous intracranial hypotension on quality of life, work ability and disability.

BACKGROUND: Spontaneous intracranial hypotension (SIH), characterized by headaches due to cerebrospinal fluid leaks or low pressure, is a challenging condition to diagnose and treat and affects the quality of life. METHODS: An 8­week online survey was conducted to assess the impact of SIH on symptoms, sociodemographics and quality of life. The cohort was comprised of patients who had a self-reported diagnosis of SIH and were divided into two groups: those with radiological evidence of SIH and those with clinical suspicion but no radiological evidence. Mental health and disability were evaluated using the Depression, Anxiety and Stress Scale-21 (DASS-21) and the Henry Ford Hospital Headache Disability Inventory (HDI). RESULTS: A total of 86 participants were included in the study, 59 with radiological evidence and 27 without. Most participants were female (84.9%) with a mean age of 44.8 years. Orthostatic headache was more common in participants without radiological evidence (74.1% vs. 42.4%). The severity in those with radiological evidence was 27.1% mild, 27.1% moderate, 30.5% severe and 15.3% extremely severe, while those without had 7.4% mild, 18.5% moderate, 63.0% severe and 11.1% extremely severe headaches. Mental health assessment using the DASS-21 scale showed that 77.9% of all participants reported signs of depression, 96.5% reported anxiety and 89.5% reported stress. The HDI showed 2.3% total disability, 40.7% severe, 19.8% moderate and 37.2% mild. The impact on employment was significant: 15.1% were able to work full-time, 48.8% part-time, 30.2% were unable to work and 5.8% retired early due to SIH. CONCLUSION: The study demonstrates the broad impact of SIH affecting physical health, mental well-being, and socioeconomic status, and calls for multifaceted and robust management approaches to address its complex effects on patients.

Epidural blood patching in an anticoagulated patient with intracranial hypotension.

A middle-aged man had classical clinical and radiographical features of spontaneous intracranial hypotension, refractory to conservative management. His medical history included antiphospholipid syndrome, autoimmune thrombocytopenia and recurrent thrombotic events. To reduce his risk from epidural blood patching, we stopped his anticoagulation, but he developed thrombosis. Despite therapeutic challenges, we performed a fluoroscopically guided epidural blood patch successfully at multiple levels, with significant symptom and radiological improvement maintained at 9 months. We review the place of epidural blood patching in people with spontaneous intracranial hypotension who either take anticoagulants or have coexisting blood disorders.

Migraine and brain structure in the elderly: The Rotterdam Study.

BACKGROUND: Recent studies suggested that persons with migraine might be at higher risk of structural brain changes, including cerebral small vessel disease and atrophy. However, findings in the literature are inconsistent, with variations observed in the direction, magnitude, and population characteristics of reported effects, and large-scale population-based evidence remains scarce. Hence, we investigated the association of migraine with structural brain changes in a middle-aged and elderly population. METHODS: Within the population-based Rotterdam Study, lifetime history of migraine was assessed using a validated questionnaire between 2006 and 2011. Magnetic resonance imaging of the brain was performed in 4920 participants (median age 61.7 [IQR 45.5, 97.5] years, 55.4% female) to assess imaging markers of cerebral small vessel disease and brain atrophy. We used linear and logistic regression models to examine the cross-sectional association of migraine with brain volumes (total grey and white matter volumes in mL) and cerebral small vessel disease markers (white matter hyperintensity volume in mL, presence of lacunes and cerebral microbleeds). Adjustments were made for age, sex, intracranial volume and cardiovascular variables. Analyses were also stratified by sex and presence of aura. RESULTS: The lifetime prevalence of migraine was 15.3% (752/4920). In multivariable adjusted regression models, we found no statistically significant differences between participants with and without migraine in terms of total brain volume (mean difference [MD]: 2.21 mL, 95% confidence interval [CI]: -0.38 ; 4.81), grey matter volume (MD: 0.38 mL, 95% CI: -1.98 ; 2.74), white matter volume (MD: 2.19 mL, 95% CI: -0.56 ; 4.93), log white matter hyperintensity volume (MD: -0.04 mL, 95% CI: -0.10 ; 0.02), presence of lacunes (odds ratio [OR]: 0.82, 95% CI: 0.58-1.15), and presence of cerebral microbleeds (OR: 0.95, 95% CI: 0.76-1.18). CONCLUSION: In this study, we found that middle-aged and elderly participants with migraine were not more likely to have structural brain changes on magnetic resonance imaging.

Comparison of two methods of greater occipital nerve block in patients with chronic migraine: ultrasound-guided and landmark-based techniques.

BACKGROUND: Migraine is a primary headache defined as moderate-to-severe pain lasting 4 to 72 h, ranking 2nd among the disabling conditions for both genders regardless of the age and the greater occipital nerve (GON) block has been reported as an efficient treatment method for migraine. The present study aims to evaluate and compare the efficiency of the two methods of GON block, i.e., the ultrasound (US)-guided technique and the landmark-based technique. METHOD: Having a prospective and randomized design, the study assigned the patients with chronic migraine into two groups after which a neurologist performed landmark-based GON block in the first group while an algologist performed US-guided GON block in the second group. During the 3-month follow-up period, the number of days with pain, the duration of pain, the number of analgesic drugs taken in a month, and Visual Analogue Scale (VAS) scores were compared with the values ​​before treatment and at the 1st week, 1st month, and 3rd month after treatment. RESULTS: US-guided GON block group included 34 patients while there were 32 patients in the landmark-based GON block group. US-guided GON block group showed significantly reduced VAS scores and frequency of attacks compared to the landmark-based GON block group at Month 1 after the procedure. After a 3-month follow-up period of the two groups, the frequency of attacks, analgesic intake and the duration of attacks were lower in both groups compared to the baseline. At 3-month follow-up, the mean of VAS scores decreased from 9,47 ± 2,69 to 4,67 ± 1,9 in US-guided GON block group and from 9,46 ± 0,98 to 7 ± 2,5 in the landmark-based GON block group. CONCLUSION: It was determined that both US-guided and landmark-based GON block were efficient techniques in patients with chronic migraine. US-guided GON block technique resulted in lower VAS scores, shorter durations of pain, lower frequencies of attack, and lower intake of analgesics compared to the landmark-based GON block technique.

The effect of physical therapy integrated with pharmacotherapy on tension-type headache and migraine in children and adolescents.

BACKGROUND: Tension-type headache (TTH) and migraine are prevalent neurological conditions in children and adolescents that significantly impact activity of daily living (ADL) and quality of life (QOL). Although physical therapy targeting cervical myofascial trigger points (MTrPs) on TTH and migraine has been extensively studied in adults, the efficacy in pediatric patients remains unexplored. The aim of this study is to reveal the effect of physical therapy integrated with pharmacotherapy on TTH and migraine in children and adolescents. METHODS: We conducted a prospective, observational cohort study recruiting consecutive patients aged 6 to 18 years with TTH and migraine with cervical MTrPs. They were classified into 4 types of headaches: frequent episodic TTH (FRTTH), chronic TTH (CTTH), episodic migraine (EM) and chronic migraine (CM). The once-weekly 40-minutes physical therapy session integrated with pharmacotherapy (integrated physical therapy) was continued until the treatment goals (headache days per week less than 2 days, headache impact test-6 (HIT-6) score to below of 50, and the ability to attend school daily) was achieved. Multifaceted assessments including headache frequency (headache days per week), headache intensity using the Visual Analogue Scale (VAS), pain catastrophizing score (PCS), hospital anxiety and depression scale (HADS) score, HIT-6 scores, and EuroQol 5 dimensions 5-level questionnaire (EQ-5D-5 L) scores, were conducted to evaluate the treatment effects. RESULTS: 161 patients were enrolled in this study. 106 patients (65.8%) were diagnosed with TTH: 70 (66.8%) with FETHH, 36 (34.0%) with CTTH, and 55 patients (34.2%) were diagnosed with migraine: 43 patients (78.2%) with EM, 12 patients (21.8%) with CM. We observed significant improvements in headache frequency, headache intensity, PCS, HADS score, HIT-6 scores, and EQ-5D-5 L scores before and after the treatment in all 4 types of headaches. The average number of sessions required to achieve the treatment goals was 4 times (weeks) for patients with FETTH and EM, 5.5 for those with CTTH, and 7.5 for those with chronic migraine. CONCLUSION: The integrated physical therapy on pediatric TTH and migraine patients with the cervical MTrPs was significantly effective in reducing headache symptoms and improving ADL and QOL.

Thunderclap headache as a first manifestation of acute disseminated encephalomyelitis: case report and literature review.

BACKGROUND: Acute Disseminated Encephalomyelitis (ADEM) is an acute demyelinating disorder of the central nervous system, characterize by multiple white matter hyperintensities on T2 MRI. Patients usually present with subacute progressive encephalopathy and polyfocal neurological deficits. Possible treatments are corticosteroids, immunoglobulins and plasma exchange. Full clinical recovery is seen in more than half of the cases. CASE: We describe a case of a 62-year-old patient presenting with thunderclap headache as the first symptom, two weeks after an upper respiratory tract infection. The clinical course was complicated by progressive coma and intracranial hypertension mandating external ventricular drainage and sedation. Initial treatment with methylprednisolone was unsuccessful but clinical resolution and radiological regression was achieved after plasma exchanges and cyclophosphamide. CONCLUSION: To our knowledge, this is the first reported case of ADEM presenting with thunderclap headache. Intracranial hypertension with the need for invasive neuromonitoring and pressure management is also a very rare complication of ADEM. In this report, we describe the findings of the literature review concerning ADEM, thunderclap headache and intracranial hypertension.
