RESUMO
Introduction: Intravenous (IV) lidocaine has been used as a transitional treatment in headache and facial pain conditions, typically as an inpatient infusion over several days, which is costly and may increase the risk of adverse effects. Here we report on our experience using a single one-hour IV lidocaine infusion in an outpatient day-case setting for the management of refractory primary headache disorders with facial pain and trigeminal neuralgia. Methods: This is a retrospective, single-center analysis on patients with medically refractory headache with facial pain and trigeminal neuralgia who were treated with IV lidocaine between March 2018 and July 2022. Lidocaine 5 mg.kg-1 in 60 mL saline was administered over 1 h, followed by an observation period of 30 min. Patients were considered responders if they reported reduction in pain intensity and/or headache frequency of 50% or greater. Duration of response was defined as short-term (< 2 weeks), medium-term (2-4 weeks) and long-term (> 4 weeks). Results: Forty infusions were administered to 15 patients with trigeminal autonomic cephalalgias (n = 9), chronic migraine (n = 3) and trigeminal neuralgia (n = 3). Twelve patients were considered responders (80%), eight of whom were complete responders (100% pain freedom). The average duration of the treatment effect for each participant was 9.5 weeks (range 1-22 weeks). Six out of 15 patients reported mild and self-limiting side effects (40%). Conclusion: A single infusion of IV lidocaine might be an effective and safe transitional treatment in refractory headache conditions with facial pain and trigeminal neuralgia. The sustained effect of repeated treatment cycles in some patients may suggest a role as long-term preventive therapy in some patients.
RESUMO
INTRODUCTION: Although migraine prevalence decreases with aging, some older patients still suffer from chronic migraine (CM). This study aimed to investigate the outcome of OnabotulinumtoxinA (OBT-A) as preventative therapy in elderly CM patients. METHODS: This is a post hoc analysis of real-life prospectively collected data at 16 European headache centers on CM patients treated with OBT-A over the first three treatment cycles (i.e., Cy1-3). We defined: OLD patients aged ≥ 65 years and nonOLD those < 65-year-old. The primary endpoint was the changes in monthly headache days (MHDs) from baseline to Cy 1-3 in OLD compared with nonOLD participants. The secondary endpoints were the responder rate (RR) ≥ 50%, conversion to episodic migraine (EM) and the changes in days with acute medication use (DAMs). RESULTS: In a cohort of 2831 CM patients, 235 were OLD (8.3%, 73.2% females, 69.6 years SD 4.7). MHDs decreased from baseline (24.8 SD 6.2) to Cy-1 (17.5 SD 9.1, p < 0.000001), from Cy-1 to Cy-2 (14.8 SD 9.2, p < 0.0001), and from Cy-2 to Cy-3 (11.9 SD 7.9, p = 0.001). DAMs progressively reduced from baseline (19.2 SD 9.8) to Cy-1 (11.9 SD 8.8, p < 0.00001), to Cy-2 (10.9 SD 8.6, p = 0.012), to Cy-3 (9.6 SD 7.4, p = 0.049). The 50%RR increased from 30.7% (Cy-1) to 34.5% (Cy-2), to 38.7% (Cy-3). The above outcome measures did not differ in OLD compared with nonOLD patients. CONCLUSION: In a population of elderly CM patients with a long history of migraine OBT-A provided a significant benefit, over the first three treatment cycles, as good as in non-old patients.

BACKGROUND: Initial evidence have shown the short-term efficacy of sTMS in the acute and preventive treatment of migraine. It is unknown whether this treatment approach in the long-term is effective and well tolerated in difficult-to-treat migraine. METHODS: This is a prospective, single centre, open-label, real-world analysis conducted in difficult-to-treat patients with high-frequency episodic migraine (HFEM) and chronic migraine (CM) with and without medication overuse headache (MOH), who were exposed to sTMS therapy. Patients responding to a three-month sTMS treatment, continued the treatment and were assessed again at month 12. The cut-off outcome for treatment continuation was reduction in the monthly moderate to severe headache days (MHD) of at least 30% (headache frequency responders) and/or a ≥ 4-point reduction in headache disability using the Headache Impact test-6 (HIT-6) (headache disability responders). RESULTS: One hundred fifty-three patients were included in the analysis (F:M = 126:27, median age 43, IQR 32.3-56.8). At month 3, 93 out of 153 patients (60%) were responders to treatment. Compared to baseline, the median reduction in monthly headache days (MHD) for all patients at month 3 was 5.0 days, from 18.0 (IQR: 12.0-26.0) to 13.0 days (IQR: 5.75-24.0) (P = 0.002, r = - 0.29) and the median reduction in monthly migraine days (MMD) was 4.0 days, from 13.0 (IQR: 8.75-22.0) to 9.0 (IQR: 4.0-15.25) (P = 0.002, r = - 0.29). Sixty-nine out of 153 patients (45%) reported a sustained response to sTMS treatment at month 12. The percentage of patients with MOH was reduced from 52% (N = 79/153) at baseline to 19% (N = 29/153) at month 3, to 8% (N = 7/87) at month 12. There was an overall median 4-point reduction in HIT-6 score, from 66 (IQR: 64-69) at baseline to 62 at month 3 (IQR: 56-65) (P < 0.001, r = - 0.51). A total of 35 mild/moderate adverse events were reported by 23 patients (15%). One patient stopped sTMS treatment due to scalp sensitivity. CONCLUSIONS: This open label analysis suggests that sTMS may be an effective, well-tolerated treatment option for the long-term prevention of difficult-to-treat CM and HFEM.

BACKGROUND AND PURPOSE: The management options for chronic cluster headache (CCH) are limited and a significant proportion of patients become refractory to pharmacological treatments. Pulsed radiofrequency (PRF) of the sphenopalatine ganglion (SPG) may present an efficacious, minimally invasive treatment modality for patients with refractory CCH. We describe the clinical outcomes of 14 patients with refractory CCH treated with PRF of the SPG. METHODS: Patients with medically refractory CCH who underwent percutaneous SPG-PRF treatment between January 2016 and April 2019 were included in this report. Patients obtaining at least 30% reduction in weekly cluster attacks for at least 3 months were defined as responders. Treatment-related side effects were collected. RESULTS: A total of 14 patients were included in this report (nine males). At a median follow-up of 6.5 (range 6-13) months post-procedure, eight patients (57.1%) were defined as responders to the treatment. Six patients were non-responders and reported either a reduction in frequency and severity of attacks for <3 months (2/6), no improvement (2/6) or temporary worsening of symptoms (1/6). The majority of patients (63.6%, n = 7/11) treated with >45 V were responders compared with responders treated with 45 V (33.3%, n = 1/3). Five patients (35.7%) experienced post-procedural side effects. CONCLUSION: This case series suggests that PRF targeting the SPG might offer a safe, minimally invasive and effective treatment for medically refractory CCH. Given the small number of cases and the short follow-up, larger and more robust studies will be needed to confirm our findings.

This study assessed the impact of collaborative working with a headache neurologist on diagnoses of patients attending orofacial pain (OFP) clinic. Patient diagnostic data was collected from adult patients attending an Orofacial Pain Service from January 2013 to January 2017. A liaison headache neurologist was appointed late 2015; OFP clinics were co-run with the neurologist specialist thereafter. Overall, 639 patients attended the service; 315 in 2013-2015 and 324 in 2016-2017. Compared to 2013-2015, there were increased rates of diagnoses related to neurovascular (27.5% vs. 19.0%; P=.012) and musculoskeletal pain (36.9% vs. 26.0%; P=.003) in the 2016-2017 cohort and decreased rates of neuropathic (55.6% vs. 70.2%; P<.001) and atypical/idiopathic pain (1.3% vs. 5.4%; P=.003) diagnoses. There was a trend towards an increased rate of comorbid diagnoses (26.3% vs. 20.3%; P=.077), especially those relating to headache conditions. The findings suggest that introduction of a specialist headache neurologist into the OFP clinic widened its remit of assessment, increasing recognition of (co-morbid) neurovascular-related pain and decreasing atypical/idiopathic pain diagnoses in patients with complex OFP. The increase rate of musculoskeletal pain diagnosis in the later cohort is likely attributable to service expansion and normalisation of diagnostics reportedly seen in other OFP services. Statement of clinical relevance: Orofacial pain is a complex diagnosis, it requires a multidisciplinary approach that includes neurological input.

BACKGROUND AND PURPOSE: The National Institute for Health and Care Excellence (NICE) in the UK recommends the use of OnabotulinumtoxinA (BoNTA, Botox® ) in the management of chronic migraine (CM) following specific guidelines within the National Health Service. In view of the lack of data on the efficacy of this therapy following implementation of these guidelines in clinical practice and on the evaluation of guidance compliance, we aimed to evaluate the effectiveness and safety of BoNTA in patients with CM following the NICE guidelines. METHODS: This was a prospective real-life audit study. RESULTS: After two treatments, 127 of 200 patients (63.5%) obtained at least a 30% reduction in headache days. Those who continued the treatment up to 3 years reported a stable beneficial effect compared with baseline. Amongst responders, 68 patients (53.5%) were reclassified as episodic migraineurs. A total of 57 of these patients (83.8%) converted to an episodic migraine pattern at 6-month follow-up. The majority of those whose migraine became episodic after BoNTA extended the treatment intervals beyond 3 months (range 4-8 months) before noticing any worsening of headache. We observed no significant differences in the efficacy measures in patients treated with 155 U BoNTA compared with those treated with >155 U BoNTA. CONCLUSIONS: When administered according to the NICE guidance, BoNTA produced a clinically meaningful effect in the long-term management of CM with and without medication overuse headache. Treatment discontinuation when CM becomes episodic may be useful in clinical practice to identify those who may benefit from extended treatment intervals. Our clinical experience indicates a lack of additional benefit from using the 'follow-the-pain' paradigm.

BACKGROUND AND PURPOSE: Greater occipital nerve blockade (GONB) has been shown to be effective in episodic cluster headache. However, its use in chronic cluster headache (CCH) is less certain. The study aims to prospectively assess the efficacy and consistency of response to GONB in a large series of CCH patients. METHODS: CCH patients who had a unilateral GONB and were referred to the National Hospital for Neurology and Neurosurgery were studied prospectively. Headache characteristics were collected using headache diaries. Responders were considered to be patients with a complete or partial response lasting at least 7 days. In a subgroup of responders the outcomes of serial GONB performed at 3-monthly intervals were also analysed. RESULTS: Eighty-three CCH patients were studied. After the first GONB, a positive response was observed in 47 (57%) patients: 35 (42%) were rendered pain free, 12 (15%) had a partial benefit and one patient obtained <50% improvement. The duration of a positive response lasted a median of 21 days (range 7-504 days). There was a transient worsening of condition in 6% of patients. The overall rate and average duration of response remained consistent after the second [n = 37; 31 responders (84%); median duration 21 days], third [n = 28; 20 responders (71%); median duration 25 days] and fourth [n = 14; 10 responders (71%); median duration 23 days] injections. CONCLUSION: GONB seems to be an efficacious treatment with reproducible effects in CCH patients. Performed three monthly, GONB may have a useful role in the management of CCH.

Data in the literature on cluster headache (CH) indicate a mean age at onset of about 29-30 years; recently, however, cases have been reported with onset in old age. A review of age at onset in all CH patients (n = 693) followed at the University of Parma Headache Centre between 1976 and 2011 shows that 73 (10.5 %) patients began to suffer from CH after age 50. In these 73 patient, the gender (M:F) ratio was 1.4:1, while in the 620 patients with CH onset before age 50, it was 2.5:1. In the patients with CH onset after and before age 50, respectively, the distribution by CH subtype shows that the episodic-to-chronic ratio was 7.6:1 and 7.9:1 in men and 1.5:1 and 7.8:1 in women. In episodic CH men with onset after 50 the average duration of active periods was 60 versus 39 days for those with onset before 50. In women, the duration was 80 and 42 days, respectively. In conclusion, our case review suggests that CH onset after age 50 is not rare, especially in women. Additionally, late onset represents a negative prognostic factor because, particularly in women, CH will more likely be a chronic form and even in episodic forms active periods will last longer.

Primary headache prevalence in the adult Italian general population has been little studied so far. This is an observational, cross-sectional, population-based study conducted in a subject sample that was representative of the city of Parma's general population >or=age 18. The lifetime prevalence of headache was 69.1%, i.e. 75.8% in women and 60.6% in men; the past-year prevalence of headache was 42.8%, i.e. 52.0% in women and 31.1% in men. Most people suffer from one headache subtype. Headache past-year prevalence decreases with age, both in men and in women. After 60, the likelihood of suffering from headache is low. In more than 80% of cases, headache starts before age 40 and, therefore, it is not very likely for people to develop headache at an advanced age (>50 years). This is the first population-based study conducted in Italy on a sample aged >or=18 since the publication of the IHS diagnostic criteria in 1988.

Headache is a disorder that has a very negative personal and social impact. This is an observational, cross-sectional, population-based study conducted in a subject sample (n = 904) that was representative of the town of Parma's general population aged 18 and over. The aim of this study, which is a part of a larger project, was to assess the frequency of headache and the disease perception of subjects with headache during the past year (n = 387). The average number of headache days in the past year was 34.9 days and it was comparable in men and in women: 49.9% of subjects had 1-12 days of headache in the past year, 34.9% had 1-52 days, 11.9% had 53-180 days, and 3.4% had more than 180 days. Only three subjects had headache every day during the past year. Only one-third of the subjects with headache in the past year considered themselves headache sufferers. The analysis by gender showed differences between men and women: although the average number of headache days in the past year was comparable in the male and female populations, women considered their headache a disease more often than men did. In addition, the percentage of men who considered their headache a disease did not increase with the increase in the number of headache days in the past year. More in-depth studies on this important aspect are needed.

Migraine without aura is typically considered a female condition. The purpose of this study was to determine if there have been any changes in the female-to-male ratio of the disease over time. We included in the study all patients with migraine without aura (n = 3457) referred to the Parma University Headache Centre between 1976 and 1995. They were divided into subgroups with respect to gender and year-range of onset of migraine (before 1960, in the 1960s, in the 1970s, in the 1980s, and between 1990 and 1995). Gender ratio ranged from 3.6:1 (in patients with onset before 1960) to 2.8:1 (in patients with onset in the 1980s), with no statistically significant changes during the observation period.

Chronic migraine appeared for the first time in the second edition of the International Classification of Headache Disorders (ICHD-II) in 2004, listed among the complications of migraine. Unfortunately, the diagnostic criteria of ICHD-II for this headache form tend to equate it with a migraine with a high frequency of attacks, rather than with an unfavourable evolution of migraine with loss of symptom-free intervals between attacks. On the other hand, the latter occurrence has increasingly been described in the last few years with the term "transformed migraine". Therefore, it seems advisable to carry out a revision of the ICHD-II in order to: (a) subdivide migraine at the three-digit level into infrequent episodic, frequent episodic and chronic migraine; and (b) introduce transformed migraine among the complications of migraine.

General population studies suggest a non-casual association (comorbidity) between migraine, major depression and anxiety disorders (panic attack disorder, obsessive-compulsive disorder, generalised anxiety disorder). The risk of developing affective and anxiety disorders is not increased uniformly in the different migraine subtypes, but it is more elevated in migraine with aura patients. The relationship between migraine and depression is "bi-directional" (i. e., migraineurs have a more than three-fold risk of developing depression compared with non-migraine patients, while depression patients that have never suffered from migraine before have a more than three-fold risk of developing migraine compared with nondepressed patients) and specific (i. e., the presence of migraine or severe non-migraine headache increases a patient's risk of developing depression or panic attack disorder, whereas the presence of depression or panic attack disorder is associated with a greater risk of developing migraine, but not severe non-migraine headache). Comorbidity with psychiatric disorders has also been described for chronic tension-type headache and for chronic daily headache, although these findings are based only on clinical population data.
