RESUMO
BACKGROUND: Occipital nerve stimulation (ONS) is a treatment with evidence in refractory chronic cluster headache (CCH). However, the variable response rate and cost make it necessary to investigate predictors of response. METHODS: This is a cross-sectional study conducted through the review of medical records of CCH patients from six hospitals in Madrid. Epidemiological and clinical variables were compared between patients with ONS failure and the rest. ONS failure was defined as the need for device withdrawal or switch off because of lack of response or adverse events. RESULTS: From a series of 88 CCH, 26 (29.6%) underwent ONS surgery, of whom 13/26 (50.0%) failed because lack of response. ONS failure group had an earlier headache onset (mean ± SD) of 27.7 ± 6.9 vs. 36.7 ± 11.8 years, p = 0.026) and a higher smoking rate (100% vs. 42.9%, p = 0.006). Stational fluctuations (58.3% vs. 7.7%, p = 0.007) and nocturnal exacerbations (91.7% vs. 53.9%, p = 0.035) were more frequent in the ONS failure group as well. There was no difference between groups in diagnostic delay, years of evolution prior to surgery, mental illness, comorbidity with other headache disorders or chronic pain conditions or prior response to occipital nerves anesthetic blocks. CONCLUSIONS: Some clinical features such as an early debut, smoking and seasonal or circadian fluctuations could be related to failure of ONS in refractory CCH.

BACKGROUND AND PURPOSE: Anti-calcitonin gene-related peptide (CGRP) therapies are recent preventive therapies approved for both episodic and chronic migraine. One of the measures of effectiveness is the withdrawal of other preventive treatments. The objective of this study is to quantify the impact of anti-CGRP drugs in concomitant preventive treatment in patients with migraine. METHODS: This was an observational, retrospective, multicenter cohort study with patients from nine national headache units. Patients with migraine undergoing treatment for at least 6 months with anti-CGRP antibodies, who were initially associated with some preventive treatment (oral and/or onabotulinumtoxinA) were included. Demographic and clinical variables were collected, as well as variables related to headache. Differences according to withdrawal or nonwithdrawal were evaluated. RESULTS: A total of 408 patients were included, 86.52% women, 48.79 (SD = 1.46) years old. Preventive treatment was withdrawn in 43.87% (179/408), 20.83% partially and 23.04% totally. In 27.45% (112/408), it was maintained exclusively due to comorbidity and in 28.6% (117/408) due to partial efficacy. The most frequent time of withdrawal was between 3 and 5 months after the start of treatment. The baseline characteristics associated with nonwithdrawal were comorbidities: insomnia, hypertension and obesity, chronic migraine, and medication overuse. In the multivariate analysis, the absence of high blood pressure, a greater number of preventive treatments at the start, and a lower number of migraine days/month after anti-CGRP treatment were independently associated with withdrawal of the treatment (p < 0.05). CONCLUSIONS: Anti-CGRP antibodies allow the withdrawal of associated preventive treatment in a significant percentage of patients, which supports its effectiveness in real-life conditions.

OBJECTIVE: To evaluate clinical characteristics, effectiveness, and tolerability of preventive anti- calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) in the elderly. Anti-CGRP mAbs have demonstrated efficacy and safety in patients with migraine although there is limited information regarding the elderly. DESIGN: We performed a multicenter case-control study of cases (patients over 65 years old) and controls (sex-matched patients under 55 years old) with migraine receiving anti-CGRP mAbs. METHODS: We included the demographic characteristics, effectiveness-reduction in the number of monthly headache days (MHD) and monthly migraine days (MMD), 30%, 50%, and 75% responder rates-and treatment emergent adverse events (TEAEs). The primary endpoint was the 50% response rate regarding MHD at weeks 20-24; exploratory 50% response predictors in the elderly were evaluated. RESULTS: In total, 228 patients were included: 114 cases , 114 controls-. Among cases 84.2% (96/114) were women, 79.8% (91/114) CM; mean age of cases 70.1 years old (range: 66-86); mean age of controls was 42.9 years old(range: 38-49). Cases had a higher percentage of vascular risk factors (P < .05),older age of onset (P < .001) and more reported prior preventive treatments (P < .001). Regarding effectiveness in cases, 50% response rate was achieved by 57.5% (42/73) at 20-24 weeks, with lower reduction in the MHD at 8-12 weeks (5 [7.2], 8 [9.1]; P = .001) and a higher reduction in MMD at 20-24 weeks (10.7 [9.1], 9.2 [7.7]; P = .04) compared to the control group. The percentage of TEAEs was similar in the 2 groups. Diagnosis of episodic migraine (EM) (P = .03) and lower number of MHD at baseline (P = .001) were associated with a 50% response in the elderly in univariate analysis. CONCLUSIONS: Our study provides real world evidence of effectiveness and safety of anti-CGRP mAbs for migraine in patients without upper age-limit and possible predictors of anti-CGRP response in the elderly.

INTRODUCTION: Chronic cluster headache (CCH) is a relatively rare primary headache disorder whose management is often challenging. The prevalence of refractory CCH (rCCH) is unknown. Our aim is to describe the frequency of rCCH within a population of CCH, define the clinical profile of the refractory patients and the treatments they underwent. METHODS: We conducted a cross-sectional study through a review of the medical records of CCH patients in six hospitals in Madrid, Spain. Data on epidemiological, clinical presentation, treatment and disease activity at the moment were collected. The European Headache Federation diagnostic criteria were used for rCCH definition. High disease activity was defined as having at least 3 severe attacks per week that impact quality of life despite treatment. Non-rCCH and rCCH groups were compared. RESULTS: 88 CCH patients were analyzed, 68.2% (60/88) met rCCH criteria at some point in their evolution. A longer diagnostic delay (4.6 ± 7.1 vs. 3.2 ± 3.7 years, p = 0.017) was observed in rCCH. All rCCH patients tried therapies without established evidence from randomized clinical trials. OnabotulinumtoxinA and galcanezumab were initiated in 77.3% (68/88) and 5.7% (5/88), but discontinued in 52.9% (36/68) and 60.0% (3/5), respectively. Occipital nerve stimulation (ONS) was implanted in 29.6% (26/88), with 50.0% (13/26) still active. Other treatment options are described and discussed. Despite treatment, 60.2% (53/88) still have high disease activity. CONCLUSION: CCH is a disorder with poor prognosis, meeting refractoriness criteria in more than half. OnabotulinumtoxinA and ONS could be the effective in refractory patients.
RESUMO
BACKGROUND: Clinical presentation is the key to the diagnosis of patients with migraine and tension-type headache, but features may overlap when both become chronic. Psychophysical parameters may distinguish both conditions. We aimed to compare psychophysical aspects of patients with chronic migraine, chronic tension-type headache and headache-free controls, and to determine whether these can predict headache frequency. METHODS: An examiner blinded to the diagnosis assessed 100 participants (chronic migraine (n = 38), chronic tension-type headache (n = 31) and controls (n = 31)). Assessed variables included painful area, pressure pain thresholds, temporal summation, cervical range of motion, neck posture, headache and neck impact, quality of life, and kinesiophobia. Comparison between groups was performed with one-way ANOVA and multiple linear regression was used to assess the headache frequency predictors. RESULTS: We found differences of both headache groups compared to controls (p < 0.01), but not between headache groups. Neck disability was a significant predictor of headache frequency for chronic tension-type headache (adjusted R2 = 0.14; ß = 0.43; p = 0.03) and chronic migraine (adjusted R2 = 0.18; ß = 0.51; p < 0.01). CONCLUSIONS: Chronic tension-type headache and chronic migraine showed similar psychophysical results, but were significantly worse when compared to controls. The psychophysical examination did not discriminate between headache types. The variable best explaining headache frequency for both headache types was neck disability.

BACKGROUND: Headache is a frequent symptoms of coronavirus disease 2019 (COVID-19). Its long-term evolution remains unknown. We aim to evaluate the long-term duration of headache in patients that presented headache during the acute phase of COVID-19. METHODS: This is a post-hoc multicenter ambisective study including patients from six different third-level hospitals between 1 March and 27 April 2020. Patients completed 9 months of neurological follow-up. RESULTS: We included 905 patients. Their median age was 51 (IQR 45-65), 66.5% were female, and 52.7% had a prior history of primary headache. The median duration of headache was 14 (6-39) days; however, the headache persisted after 3 months in 19.0% (95% CI: 16.5-21.8%) and after 9 months in 16.0% (95% confidence interval: 13.7-18.7%). Headache intensity during the acute phase was associated with a more prolonged duration of headache (Hazard ratio 0.655; 95% confidence interval: 0.582-0.737). CONCLUSION: The median duration of headache was 2 weeks, but in approximately a fifth of patients it became persistent and followed a chronic daily pattern.

BACKGROUND: To study the effect of greater occipital nerve (GON) block on migraine-associated photophobia levels. Photophobia is one of the most bothersome symptoms reported by migraine patients. Studies investigating the impact of migraine treatment on this symptom are scarce. METHODS: This is an observational prospective case-control study. Patients with migraine and photophobia attending a Headache Clinic were recruited. Cases were defined as patients in whom GON block was performed, following usual clinical practice guidelines. All patients were evaluated with the Hospital Anxiety and Depression Scale, the Migraine Specific Quality of Life Questionnaire, the Utah Photophobia Symptom Impact Scale (UPSIS-12), and the Korean Photophobia Questionnaire (KUMC-8); both in the first visit (V1) and one week after (V2). RESULTS: Forty-one patients were recruited, 28 (68.3%) cases and 13 (31.7%) controls. At V1, there were no significant differences in the median [p25-p75] score of UPSIS-12 in cases vs controls (32.0 [21.0-34.0] vs 30.5 [22.0-37.0], P = 0.497) or KUMC-8 (6.5 [5.5-7.0] vs 7.0 [6.0-8.0], P = 0.463). At V2, cases experimented a significant improvement in UPSIS-12 of -5.5 [-8.8 to -1.3] and in KUMC-8 of -0.5 [-2.0 to 0], whereas there were no significant changes in the control group. Migraine with aura patients presented higher UPSIS-12 score at V1 (33.5 [24.5-37.0] vs 26.0 [16.0-35.0]) and lesser improvement at V2 after GON block compared with migraine without aura patients (-4.0 [-6.0 to -1.0] vs -8.0 [-17.0 to -2.0]), although statistical significance was not achieved ( P = 0.643 and P = 0.122, respectively). There was no significant variation in the remaining scales. CONCLUSIONS: Greater occipital nerve block improves migraine-associated photophobia, measured with UPSIS-12 and KUMC-8. Patients without aura may exhibit a greater improvement. Physicians could consider GON block for management of photophobia in migraine patients.

Migraine continues second among the world's causes of disability. Diagnosis is based on the history and clinical examination and imaging is usually not necessary. Migraine can be subdivided depending on whether there is an aura or not and based on the frequency of the headaches. The number of headache days determines whether the patient has episodic migraine or chronic migraine. Treating migraines can be done to treatment the migraine itself and to prevent its appearance. In this review we approach the migraine from a practical point of view with updated information.

OBJECTIVE: To compare the presence of allodynia, pain catastrophizing, and the impact of headaches on patients with cluster headache (CH) and healthy individuals. Our second aim was to analyze the relationship between catastrophism, psychological comorbidities, and the impact in CH. METHODS: We designed this cross-sectional study to compare various factors among 47 patients diagnosed with CH and 40 healthy controls, and then focus on catastrophism, anxiety, depression, and impact in the CH group. RESULTS: There were statistically significant differences between CH and the asymptomatic group in Allodynia Symptom Checklist (ASC) (p < 0.001), Pain Catastrophizing Scale (p < 0.001), and HIT-6 (p < 0.001) scores. We found a correlation among ASC, PCS, anxiety-depression, EuroQoL, and HIT-6 for the CH group. In this group, we observed a strong positive correlation between PCS and anxiety (rho = 0.69; p < 0.001), PCS and depression (rho = 0.62; p < 0.001) and depression and EuroQoL (rho = - 0.68; p < 0.001). The regression model showed that the combination of anxiety and HIT-6 was a significant predictor of PCS (adjusted R2 = 0.52). DISCUSSION: Our findings reveal significant differences regarding allodynia, pain catastrophism, and impact in CH group compared with controls. We found a significant relationship between psychological comorbidity, pain catastrophism, and quality of life in CH patients. Anxiety and HIT-6 were a predictor (adjusted R2 = 52%) of pain catastrophism. Screening for these comorbidities should be implemented through a multidisciplinary approach.

BACKGROUND: The presence of abrupt anisocoria in clinical examination usually leads to the performance of urgent neuroimaging studies to exclude intracranial hemorrhage, although unilateral mydriasis might be the result of other benign etiologies. CASE REPORT: In this work, we report an illustrative case of a patient presenting with sudden-onset anisocoria while receiving ipratropium bromide nebulization in the emergency department to treat acute asthma. No other abnormalities were found on neurological examination and the computed tomography scan was normal. As a muscarinic antagonist, ipratropium bromide can produce mydriasis if accidentally instilled on one eye, thus leading to the suspicion of pharmacologic mydriasis. The pupils became isocoric after the discontinuation of the drug. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: A careful neurological examination and the history of treatment with mydriatic drugs might avoid unnecessary tests and radiation exposure.

OBJECTIVE: To describe the semiology of pain and its associated features in patients with coronavirus disease 2019 (COVID-19) and headache presenting to the emergency department who do not require urgent services. BACKGROUND: Headache is one of the most frequent neurological symptoms reported in case series, epidemiological studies, and meta-analyses of COVID-19, with a prevalence ranging from 8 to 71.1%. Studies addressing the semiology of these headaches are lacking. METHODS: We conducted a cross-sectional study in the emergency department of a tertiary hospital. Patients classified according to the Manchester Triage System as standard and non-urgent and those fulfilling the criteria for probable or confirmed COVID-19 according to World Health Organization guidelines who presented with headache were included. A standardized questionnaire was used for data collection. RESULTS: Of the 145 confirmed and probable COVID-19 patients, 99 (68.3%) reported headache. A total of 54/99 (54.5%) were classified with probable COVID-19 and 45/99 (45.5%) with confirmed COVID-19. The mean age (44.7 ± 11.8 vs 40.4 ± 10.7, P = .061), sex distribution (35/54 [64.8%] vs 28/45 [62.2%] female, P = .768), and headache comorbidity (19/54 [35.2%] vs 17/45 [37.8%], P = .789) were similar between the probable and confirmed COVID-19 groups, along with other medical comorbidities and laboratory data. Patients with confirmed COVID-19 showed a higher incidence of anosmia (21/54 [38.9%] vs 28/45 [62.2%], P = .021) and pneumonia (10/54 [18.5%] vs 18/45 [40%], P = .018), headache at onset (32/54 [59.3%] vs 39/45 [86.7%], P = .002), and hospital admission (0/54 [0%] vs 2/45 [11.1%], P = .017). In most cases, the headache appeared simultaneously with other COVID-19 symptoms (57/99, 57.6%). It was bilateral (86/99, 86.9%), frontal or holocranial (34/99, 34.3% each) in location and intense (60/99, 60.6%, reported a visual analog scale [VAS] score ≥7). A total of 39/99 (39.4%) identified triggers, most commonly fever. The most frequent aggravating factors were physical activity (45/99, 45.5%) and coughing (43/99, 43.4%). Patients showed a propensity toward prostration (41/99, 41.4%), photophobia (29/99, 29.3%), and phonophobia (27/99, 27.3%). Partial (53/99, 53.5%) or total (26/99, 26.3%) responses to first-step analgesics were reported. A total of 25/99 (25.3%) patients had a prior history of migraine, presenting with headache different from the usual in 23/25 (92.0%) patients. Individuals with migraine were more likely to have earlier (headache at onset of the respiratory symptoms in 24/25 [96.0%] vs 57/74 [77.0%], P = .023 [95% CI: 0.067, 0.313]), longer (>24 hours of pain in 20/25 [80%] vs 25/74 [33.8%], P < .001 [95% CI: 0.272, 0.652]), and more intense (VAS score ≥5 in 25/25 [100%] vs 63/74 [85.1%], P = .043 [95% CI: 0.057, 0.213]) headaches than patients without migraine. CONCLUSIONS: Headache is a very prevalent COVID-19 symptom among patients presenting to the emergency room, most frequently presenting as holocranial or bifrontal moderate to severe, and pressing quality headache. Individuals with migraine tend to present with earlier, longer, and more intense headaches.

OBJECTIVE: To investigate central sensitization (CS) in cluster headache (CH) and to evaluate its relationship with disease characteristics and psychological comorbidities. DESIGN: Cross-sectional study. SETTINGS: Whether CS occurs in CH, as it does in other primary headaches, is a subject of debate. Few studies have evaluated the presence of CS and its relationship with psychological comorbidities in patients with CH. SUBJECTS: Twenty patients with episodic or chronic CH and 16 healthy controls were recruited. METHODS: The variables evaluated included frequency, intensity and duration of headache attacks, pressure pain thresholds (PPTs) and wind-up (WU) ratios of pain bilaterally measured over trigeminal and extratrigeminal areas, and results of questionnaires regarding anxiety and depression (Hospital Anxiety and Depression Scale [HADS], Beck Depression Inventory [BDI], State-Trait Anxiety Inventory [STAI]), quality of life (Short Form-36 [SF-36]), headache impact (Headache Impact Test [HIT-6]), and allodynia (Allodynia Symptom Checklist [ASC]). RESULTS: PPT levels were significantly lower in the CH group compared with the healthy participants (all tested points, P < 0.001). No differences were found in WU ratios between groups. However, differences in HADS (P < 0.01), BDI (P < 0.01), STAI (P < 0.01), SF-36 (P < 0.01), HIT-6 (P < 0.001), and ASC (P < 0.01) were observed between groups. The healthy group showed a moderate negative correlation between SF-36 and BDI (rho = -0.59, P = 0.03). Likewise, the CH group showed a moderate negative correlation between frequency and BDI (rho = -0.52, P = 0.03), a strong positive correlation between duration and HADS (rho = 0.86, P < 0.01), and a moderate negative correlation between intensity and PPT over symptomatic V1 (rho = -0.66, P < 0.01) and over asymptomatic V1 (rho = -0.65, P < 0.01). The CH group also showed a moderate negative correlation between SF-36 and anxiety and depression variables. CONCLUSIONS: Our findings show that patients with CH have lower PPT levels at cranial and extracranial points, suggesting, as in other primary headaches, the presence of CS. We have also found a high prevalence of psychiatric comorbidities that correlate with the length and frequency of attacks. These findings highlight the importance of a multidisciplinary approach to the treatment of patients with CH.

Our objective was to evaluate the effect of anticoagulation on cardioembolic stroke (CS) severity, outcomes, and response to intravenous thrombolysis (IVT). Observational study of CS patients admitted to a Stroke Center (2010-2013). The sample was classified into three groups based on pre-stroke oral anticoagulants (OAC) treatment (all acenocumarol) and the international normalized ratio (INR) on admission: (1) non-anticoagulated or anticoagulated patients with INR <1.5, (2) anticoagulated with INR 1.5-1.9 and (3) anticoagulated with INR ≥2. We compared demographic data, vascular risk factors, symptomatic intracranial hemorrhage, severity on admission (NIHSS) and 3 month outcomes (mRS). Overall 475 patients were included, 47.2 % male, mean age 75.5 (SD 10.7) years old, 31.8 % were on OAC. 76 % belonged to the INR <1.5 group, 13.3 % to the INR 1.5-1.9 and 10.5 % to the INR >2. 35 %of patients received IVT. Multivariate analyses showed that an INR ≥2 on admission was a factor associated with a higher probability of mild stroke (NIHSS <10) (OR 2.026, 95 % CI 1.006-4.082). Previous OAC in general (OR 2.109, 95 % CI 1.173-3.789) as well as INR 1.5-1.9 (OR 3.676, 95 % CI 1.510-8.946) were associated with favorable outcomes (mRS ≤2). OAC was not related to stroke outcomes in the subgroup of IVT patients. Therapeutic OAC levels are associated with lesser CS severity, and prior OAC treatment with favorable outcomes. In this study, OAC are not related with response to IVT.

INTRODUCTION: Acute confusional migraine (ACM) is a rare disorder characteristic of pediatric patients. Our objective was to describe the clinical characteristics of patients diagnosed with ACM who visited our pediatric emergency department (PED). METHODS: This study was a retrospective review of children who presented to our PED between January 2012 and December 2022 with a discharge diagnosis of ACM. RESULTS: During the study period, 23 patients were enrolled: 11 males (47.8%) and 12 females (52.2%); median age was 10.8 years (IQR: 8.3-13.6). Eight patients reported a history of headache. The median length of stay of PED was 4.7 h. Onset was abrupt (less than 12 h) in 100% of cases. Changes in the level and content of consciousness occurred in 47.8% and 91.3% of patients, respectively; confusion (73.9%) was the most common neurological manifestation. Eighteen patients had urgent brain CT scans, none showing pathological findings. Four patients required benzodiazepines to control their psychomotor agitation. Nine patients were hospitalized, including one in the intensive care unit. Two patients underwent MRI and one patient underwent EEG during hospitalization, with normal results. DISCUSSION: ACM is a rare condition in pediatric neurology characterized by acute onset of confusion or altered mental status before, during, or after migraine headache. Clinical features overlap with other neurological disorders, making diagnosis challenging. To improve the diagnosis, treatment, and research of AMC, it is essential to include it in the International Classification of Headache Disorders and establish standardized diagnostic criteria.
RESUMO
The objectives were 1) to synthesize quantitative sensory testing results in cluster headache (CH) patients and to identify somatosensory differences from healthy subjects (HS), and 2) between symptomatic and asymptomatic sides in CH patients. Two independent reviewers conducted a literature search in MEDLINE, EMBASE, Web of Science, and CINAHL databases. Studies with observational designs were included. Methodological quality and risk of bias were assessed with the Newcastle Ottawa Scale. The selected studies underwent qualitative and quantitative analyses. The qualitative analysis showed inconsistent findings among multiple studies. Meta-analysis showed lower pressure pain thresholds (PPTs) on the symptomatic side of CH patients than HS in V2 (standardized mean difference [SMD] -1.01 [95% confidence interval (CI) -1.79, -.23], P = .01, I2 = 73%, n = 114), V3 (SMD -1 [95% CI -1.54, .45], P < .01, I2 = 82%, n = 354), and cervical region (SMD -1.25 [95% CI -2.07, -.44], P < .01, I2 = 84%, n = 194). Furthermore, lower PPTs than those detected in HS were found on the asymptomatic side in V3 (SMD -.77 [95% CI -1.27, -.27], P < .01, I2 = 79%, n = 354) and in the cervical region (SMD -1.13 [95% CI -1.97, -.3], P < .01, I2 = 85%, n = 194). However, no differences were found in V1 or the extratrigeminal points between these groups. No significant changes were found between symptomatic and asymptomatic sides in trigeminal and extratrigeminal regions. Mechanical hyperalgesia in the trigemino-cervical region of patients with CH could suggest the presence of central pain mechanisms. These results are of clinical relevance because their presence could be associated with a poorer prognosis, chronification, and treatment response. PERSPECTIVE: This study provides consistent findings on the somatosensory profile characterizing patients with CH. Clinicians should assess PPTs and other quantitative sensory testing variables in the trigeminal and extratrigeminal (cervical) regions.

BACKGROUND: Preventive treatment for refractory chronic cluster headache (rCCH) is challenging and many therapies have been tried. OBJECTIVE: To study what could be considered the therapy of choice in rCCH through a systematic review and meta-analysis. METHODS: This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The protocol was registered in PROSPERO (ID CRD42021290983). A systematic search was performed in MEDLINE, Embase, Cochrane, clinicaltrials.gov, and the WHO's-International-Clinical-Trials-Registry-Platform. Studies on the preventive treatment for rCCH as defined by the European Headache Federation consensus statement were included. A meta-analysis of the pooled response rate was conducted for the different therapies. RESULTS: Of 336 results, 45 were eligible for inclusion. Most articles studied the effect of neuromodulation as a preventive treatment for rCCH. The most studied neuromodulation technique was occipital nerve stimulation (ONS), with a pooled response rate in the meta-analysis of 57.3% (95% CI 0.481-0.665). Deep brain stimulation (DBS) was the second most studied treatment with a pooled response rate of 77.0% (95% CI 0.594-0.957). DBS results were more heterogeneous than ONS, which could be related to the different stimulation targets in DBS studies, and reported more serious adverse events than in ONS studies. The remaining therapies (anti-CGRP pathway drugs, warfarin, ketamine-magnesium infusions, serial occipital nerve blocks, clomiphene, onabotulinum toxin A, ketogenic diet, sphenopalatine ganglion radiofrequency or stimulation, vagus nerve stimulation, percutaneous bioelectric current stimulation, upper cervical cord stimulation, and vidian neurectomy) present weaker results or have less quality of evidence. CONCLUSIONS: The results of this systematic review and meta-analysis suggest that ONS could be the first therapeutic strategy for patients with rCCH based on the current evidence.

ABSTRACT: The emergence of triptans represented a breakthrough in the treatment of migraine, but in clinical practice, patients describe symptoms that resemble those of a hangover after taking them. We propose the use of the Hangover Symptoms Scale (HSS) to evaluate this syndrome in patients that take triptans, which may help identify patients at higher risk of presenting these adverse effects that may interfere with therapeutic compliance.A cross-sectional observational pilot study with prospective data collection through a clinical-demographic questionnaire and the HSS was carried out on patients with migraine treated in headache units in 3 tertiary hospitals in Madrid.Sixty-six patients were included in the study. The median HSS was 4 and all symptoms were present in at least 15% of the patients, with difficulty to concentrate being the most frequent (57.6%). No significant differences were found between the presence of a higher HSS score and the sociodemographic characteristics of the patient or his migraine. The presence of aura was associated with a higher percentage of trembling (P = 0.029) and fatigue (nonvisual, polymodal auras; P = 0.017).According to our study, triptans are responsible for a set of symptoms overlapping with those that occur during a hangover. Therefore, we propose that the HSS could be a useful tool for the evaluation and quantification of these effects in patients receiving triptans. In addition, we found that clinical features could be more frequently associated with the appearance of these adverse effects that, however, are not related to any particular patient profile.

Introduction: Chronic pain inflicts damage in multiple spheres of patient's life and remains a challenge for health care providers. Real-world evidence derived from outcome registries represents a key aspect of the ongoing systematic assessment and future development of neurostimulation devices. Research question: The objective of the present study was to assess the long-term effectiveness of neurostimulation as a treatment for spinal chronic pain. Material and methods: The patients analyzed in the present study represent a singlecenter cohort of 52 individuals. Primary outcome measures included numeric pain rating scale, Beck depression index II and Oswestry disability index variation from baseline to 36-month visits. Secondary outcomes included its evaluation at 6-month, 12-month and 24-month visits. Results: A significant improvement in targeted pain, depression and disability values were observed at 36-month follow-up (P â< â0.001, P â= â0.009 and P â< â0.001 respectively). Those results were consistent in the leg and back pain subgroup but not in the neck, chest and arm pain subgroup. The decrease in pain, depression and disability values happened progressively through time, with the exception of the 12-month visit, where a mild stagnation was observed. Discussion and conclusion: Our results suggest that spinal cord stimulation is an effective long-term treatment for spinal chronic pain in real-world conditions when applied to a variety of patients and conditions usually seen in routine practice. Nevertheless, some fluctuations may occur during treatment so prolonged follow-up periods should be considered before rendering an unsuccessful therapy diagnosis.
RESUMO
We analyzed the inter- and intra-examiner reliability of Werium inertial sensors and the cervical range of motion (CROM) instrument for the measurement of active CROM (AcROM) in patients with primary headache. Another objective is to analyze the validity of the inertial sensors (Werium). The literature has reported symptomatology features in patients diagnosed with primary headache similar to that of patients with cervicogenic headache. The International Classification of Headache (ICHD-III) established the presence of reduced AcROM as a diagnostic criterion for cervicogenic headache. Several instruments are used for this measurement, with limitations in their applicability in daily clinical practice. A prospective longitudinal repeated measures study was conducted to assess the intra- and inter-rater reliability and validity of Werium inertial sensors in 20 adults with chronic primary headache. For the inter-rater analysis, the intraclass correlation coefficient (ICC) values were above 0.75 for all movements, indicating a good level of reliability. For the intra-rater results, the ICC values obtained by the Werium inertial sensors for all cervical movements were good for rater A (ICC >0.80) and rater B (ICC >0.84). For the validity, the ICCs obtained by the Werium inertial sensors compared with the CROM instrument for all cervical movements were moderate for both raters (ICC > 0.70, respectively). Values obtained in the standard error of measurement, minimum detectable change at 90% and limits of agreement also indicated good agreement. Werium inertial sensors have shown good to excellent reliability results, both intra- and inter-examiner (ICC > 0.75). Likewise, when the sensors were compared with another validated instrument (CROM device) they obtained high reliability results (ICC > 0.70). These results plus its relatively low price and ease of use allow us to recommend it in daily clinical practice to measure AcROM in patients with chronic primary headache.
RESUMO
Occipital nerve stimulation (ONS) is a surgical treatment proposed for drug-resistant chronic cluster headache (drCCH). Long-term series assessing its efficacy are scarce. We designed a retrospective observational study with consecutive sampling, evaluating the follow-up of 17 drCCH patients who underwent ONS. Our main endpoint was the reduction the rate of attacks per week. We also evaluated the pain intensity through the Visual Analogue Scale (VAS), patient overall perceived improvement and decrease in oral medication intake. After a median follow-up of 6.0 years (4.5-9.0), patients decreased from a median of 30 weekly attacks to 22.5 (5.6-37.5, p = 0.012), 7.5 at 1 year (p = 0.006) and 15.0 at the end of follow-up (p = 0.041). The VAS decreased from a median of 10.0 to 8.0 (p = 0.011) at three months, to 7.0 (p = 0.008) at twelve months and 7.0 (p = 0.003) at the end of the follow-up. A total of 23.5% had an overall perceived improvement of ≥70% at 3 months, 41.2% at 1 year and 27.8% at the end of follow-up. Reducing prophylactic oral medication was possible in 76.5% and it was stopped in 17.7%. Triptan use decreased in all the responder patients and 17.7% stopped its intake. A total of 41.2% presented mild adverse events. In conclusion, our long-term experience suggests that ONS could be an interesting option for drCCH-selected patients, as it is a beneficial and minimally invasive procedure with no serious adverse events.
