Healthcare resource utilization and associated costs among patients with migraine in Finland: A retrospective register-based study.

Migraine is a common chronic brain disorder, characterized by recurring and often disabling attacks of severe headache, with additional symptoms such as photophobia, phonophobia and nausea. Migraine affects especially the working age population. The objective of this retrospective observational register-based study was to analyze the use of healthcare services and associated costs in Finnish migraine patients. Study was based on aggregate data from January 1st, 2020, to December 31st, 2021, from the Finnish Institute for Health and Welfare's national registries. Patients were grouped into nine patient groups according to medication prescriptions and diagnoses. Healthcare resource utilization in specialty, primary, and occupational healthcare was assessed and analyzed separately for all-cause and migraine related healthcare contacts from a one-year period. The total number of patients was 175 711, and most (45%) of the patients belonged to a group that had used only one triptan. Migraine related total healthcare resource utilization was greater for patients that had used two or more triptans compared to those that had used only one. The patients with three or more preventive medications had the highest total migraine related healthcare resource utilization of the studied patient cohorts. Of the total annual healthcare costs 11.5% (50.6 million €) was associated to be migraine related costs. Total per patient per year healthcare costs were highest with patients that had used three or more preventive medications (5 626 €) and lowest in those with only one triptan (2 257 €). Our findings are in line with the recent European Headache Federation consensus statement regarding the unmet need in patients who have had inadequate response to two or more triptans. When assessing the patient access and cost-effectiveness of novel treatments for the treatment of migraine within different healthcare systems, a holistic analysis of the current disease burden along with potential gains for patients and healthcare service providers are essential information in guiding decision-making.

A multicenter, randomized, double-blind, placebo-controlled, crossover trial to evaluate the efficacy and safety of zolmitriptan nasal spray for the acute treatment of migraine in patients aged 6 to 11 years, with an open-label extension.

OBJECTIVE: To evaluate the efficacy and safety of zolmitriptan nasal spray (ZNS) in the acute treatment of migraine headache in patients aged 6 to 11 years. BACKGROUND: Triptans have demonstrated efficacy in adults, but pediatric studies of these agents have largely failed and there are few triptan options for these patients. Because lack of response to 1 triptan does not necessarily preclude response to an alternate triptan, additional triptan options for pediatric patients are desirable. METHODS: This Phase 3, randomized, double-blind, placebo-controlled, multicenter crossover trial with an open-label extension enrolled patients aged 6 to 11 years with a diagnosis of migraine for ≥6 months and ≥16 headache-free days/month (N = 373). After a run-in period to eliminate placebo responders, 186 patients were randomized within their body weight stratum to ZNS followed by matching placebo, or placebo followed by matching ZNS. Patients <50 kg who were randomly allocated to ZNS were randomized to 5:1 to ZNS 2.5 or 1.0 mg; those ≥50 kg were randomized 5:1 to ZNS 5.0 or 2.5 mg. Patients had 6 weeks to treat 1 moderate to severe migraine headache and then crossed over to the alternate arm, during which they had 6 weeks to treat a second migraine attack. Patients could participate in a subsequent 6-month outpatient open-label extension. The primary efficacy endpoint was pain-free status at 2 h in patients treated with the high dose from each stratum. RESULTS: The trial was terminated early due to slow enrollment. Three hundred patients (mean age, 9 years) entered the placebo run-in period and 186 entered the double-blind period. Pain-free status at 2 h postdose was achieved by 45/133 (33.8%) and 30/128 (23.4%) of patients who received high-dose ZNS and placebo, respectively (p = 0.0777; odds ratio [OR] 1.51; 95% confidence interval [CI] 0.96, 2.38). Several secondary endpoints achieved statistical significance. There were few treatment-related adverse events and none led to discontinuation. ZNS retained efficacy and demonstrated a consistent safety profile throughout the 6-month open-label extension. CONCLUSION: The effect of high-dose ZNS on the primary endpoint of pain-free status at 2 h did not achieve statistical significance. ZNS was safe and well tolerated in this pediatric population.

2022 Taiwan Guidelines for Acute Treatment of Migraine.

The Taiwan Headache Society published its guidelines for acute migraine treatment in 2017. Since then, emerging drugs and treatment options have developed rapidly. The migraine-specific drugs gepants and ditans and several noninvasive neuromodulation devices have been approved for use in Europe and the United States. Although not all emerging drugs and treatment options have been approved for use in Taiwan, keeping pace with international trends and updating treatment guidelines are imperative. Therefore, the Treatment Guideline Subcommittee of the Taiwan Headache Society reviewed the quality of recent trials, evaluated the corresponding grade of evidence, and appraised the reported clinical efficacy to reach a new consensus. To ensure that the updated Taiwan guidelines are appropriate and feasible, the subcommittee also referred to the guidelines from the United States, Europe, Canada, and other countries concerning the main roles, recommendation levels, clinical efficacy, and adverse reactions of drugs for the acute migraine treatment. Several types of drugs are currently available for acute migraine treatment in Taiwan. These drugs can be categorized into migraine-specific and migraine-non-specific. Among them, migraine-specific triptans (oral or nasal spray formulations) and migraine-nonspecific acetaminophen and NSAIDs (diclofenac, ibuprofen, naproxen) are highly recommended because they are supported by strong evidence and demonstrate high efficacy. Prochlorperazine injection has been upgraded to a highly recommended level because of the rich clinical experience for this treatment. Ergotamine/caffeine remains a second-line drug because of its lower specificity and efficacy compared with triptans. High-dose aspirin was downgraded to rescue treatment because of potential gastrointestinal side effects. Although evidence supports the combination of oral tramadol and acetaminophen, this combination should be used as a rescue treatment due to concerns about dependence. Evidence supporting the use of intravenous tramadol or morphine is insufficient; therefore, their use is not recommended. As for non-pharmacological approaches, there are only limited controlled data. The choice of treatment for acute migraine attacks should follow the concept of "stratified care." For mild to moderate migraine attacks, oral NSAIDs are the first choice, with combination analgesics, intravenous/intramuscular NSAIDs as alternatives. For moderate to severe attacks, oral or nasal spray triptans and ergotamine/caffeine compounds are recommended and should be administered in the early stage of migraine attacks. Antiemetics can be used as supplements to alleviate nausea and vomiting. Other emerging migraine-specific drugs, such as gepants or ditans, may also have a role in the future. Notably, a combination of a triptan and a NSAID yielded a better efficacy compared with either therapy alone. Parenteral steroids and fluid supply are the first-line treatment for status migrainosus. Acetaminophen is suitable for mild to moderate migraine attacks and remains the first choice for children and pregnant women. To prevent medication overuse headache, the use of acute treatment should be limited to a maximum of 2 days per week. Key words: acute migraine treatment, evidence-based medicine, treatment guidelines, triptans, ergotamine, neuromodulation.

Acute Treatments for Episodic Migraine in Adults: A Systematic Review and Meta-analysis.

Importance: Migraine is common and can be associated with significant morbidity, and several treatment options exist for acute therapy. Objective: To evaluate the benefits and harms associated with acute treatments for episodic migraine in adults. Data Sources: Multiple databases from database inception to February 24, 2021. Study Selection: Randomized clinical trials and systematic reviews that assessed effectiveness or harms of acute therapy for migraine attacks. Data Extraction and Synthesis: Independent reviewers selected studies and extracted data. Meta-analysis was performed with the DerSimonian-Laird random-effects model with Hartung-Knapp-Sidik-Jonkman variance correction or by using a fixed-effect model based on the Mantel-Haenszel method if the number of studies was small. Main Outcomes and Measures: The main outcomes included pain freedom, pain relief, sustained pain freedom, sustained pain relief, and adverse events. The strength of evidence (SOE) was graded with the Agency for Healthcare Research and Quality Methods Guide for Effectiveness and Comparative Effectiveness Reviews. Findings: Evidence on triptans and nonsteroidal anti-inflammatory drugs was summarized from 15 systematic reviews. For other interventions, 115 randomized clinical trials with 28 803 patients were included. Compared with placebo, triptans and nonsteroidal anti-inflammatory drugs used individually were significantly associated with reduced pain at 2 hours and 1 day (moderate to high SOE) and increased risk of mild and transient adverse events. Compared with placebo, calcitonin gene-related peptide receptor antagonists (low to high SOE), lasmiditan (5-HT1F receptor agonist; high SOE), dihydroergotamine (moderate to high SOE), ergotamine plus caffeine (moderate SOE), acetaminophen (moderate SOE), antiemetics (low SOE), butorphanol (low SOE), and tramadol in combination with acetaminophen (low SOE) were significantly associated with pain reduction and increase in mild adverse events. The findings for opioids were based on low or insufficient SOE. Several nonpharmacologic treatments were significantly associated with improved pain, including remote electrical neuromodulation (moderate SOE), transcranial magnetic stimulation (low SOE), external trigeminal nerve stimulation (low SOE), and noninvasive vagus nerve stimulation (moderate SOE). No significant difference in adverse events was found between nonpharmacologic treatments and sham. Conclusions and Relevance: There are several acute treatments for migraine, with varying strength of supporting evidence. Use of triptans, nonsteroidal anti-inflammatory drugs, acetaminophen, dihydroergotamine, calcitonin gene-related peptide antagonists, lasmiditan, and some nonpharmacologic treatments was associated with improved pain and function. The evidence for many other interventions, including opioids, was limited.

Melatonin- and Ferulic Acid-Based HDAC6 Selective Inhibitors Exhibit Pronounced Immunomodulatory Effects In Vitro and Neuroprotective Effects in a Pharmacological Alzheimer's Disease Mouse Model.

The structures of melatonin and ferulic acid were merged into tertiary amide-based histone deacetylase 6 (HDAC6) inhibitors to develop multi-target-directed inhibitors for neurodegenerative diseases to incorporate antioxidant effects without losing affinity and selectivity at HDAC6. Structure-activity relationships led to compound 10b as a hybrid molecule showing pronounced and selective inhibition of HDAC6 (IC50 = 30.7 nM, > 25-fold selectivity over other subtypes). This compound shows comparable DPPH radical scavenging ability to ferulic acid, comparable ORAC value to melatonin and comparable Cu2+ chelating ability to EDTA. It also lacks neurotoxicity on HT-22 cells, exhibits a pronounced immunomodulatory effect, and is active in vivo showing significantly higher efficacy in an AD mouse model to prevent both Aß25-35-induced spatial working and long-term memory dysfunction at lower dose (0.3 mg/kg) compared to positive control HDAC6 inhibitor ACY1215 and an equimolar mixture of the three entities ACY1215, melatonin and ferulic acid, suggesting potentially disease-modifying properties.

Cluster headache: state of the art of pharmacological treatments and therapeutic perspectives.

Cluster headache (CH) is the most common form of trigeminal autonomic cephalalgia. Current treatments have several limitations, and new drugs are required. This article first briefly reviews present acute and preventive treatments in CH, their mechanism of action and limitations, then describes the state of the art in recent clinical drug trials since 2015, and ends with a critique of trials in the CH field. Research is limited by lack of knowledge of pathophysiology and lack of animal models. In the past 5 years, no brand-new treatment has emerged, but promising drugs, such as CGRP(R) antibodies, are under study. According to the literature and guidelines, clinicians and researchers should be aware of many limitations in study protocols: concomitant medication, patient sample size, patients' protocol compliance, and study designs that tend to restrict patient recruitment.

Migraine treatment and healthcare costs: retrospective analysis of the China Health Insurance Research Association (CHIRA) database.

BACKGROUND: Adult migraine remains underdiagnosed and undertreated, despite significant negative effects on physical and emotional functioning. Information on prescribing patterns and treatment costs of migraine in China is limited. METHODS: This retrospective analysis of the China Health Insurance Research Association (CHIRA) medical insurance claims database in 2016 to 2017 evaluated treatment patterns, direct medical costs, and healthcare resource utilization among adults with migraine in mainland China. RESULTS: Of 108,375 patients with headache-related outpatient visits, 10,652 were adults with migraine (mean age 51.4 years, 55.4% female). Common comorbidities were major depressive disorder (4.1%), insomnia (3.8%), and anxiety (2.3%). Migraine patients were prescribed acute medication (26.4%), preventive medication (15.0%), and Chinese patent and herbal medicines (24.5% and 11.7%, respectively). Of patients prescribed acute medication, 68.8% received non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs), 7.1% received opioids, while only 3.3% received triptans. Mean annual outpatient costs per patient were 46.5 United States dollars (USD), with mean (standard deviation) 1.8 (2.0) outpatient visits per year. Medication costs for traditional Chinese medicine (22.4 USD per patient) were higher than for Western medicine (13.5 USD). CONCLUSION: Among migraine patients in China, NSAIDs were commonly prescribed as acute medication, while utilization of migraine-specific triptans and preventive medications was low.

[Modern migraine therapy-interdisciplinary long-term care]. / Moderne Migränetherapie ­ fachübergreifende Versorgung im Langzeitverlauf.

Migraine has a very high lifetime prevalence with a severe illness-related burden. As a result, extensive long-term and regular treatment is required, which cannot be covered solely by neurologists. This is particularly the case for the long-term monitoring of migraine, which often takes place over several decades. The diagnosis is made using the diagnostic criteria of the International Headache Society (ICHD-3) based on the clinical phenotype. Owing to often complex neurological symptoms, a detailed weighing up of the differential diagnoses is required, which calls for specialist neurological expertise. The same is true for follow-up appointments of more complex therapy issues. Acute therapy with antiemetics, analgesics, and triptans can, so long as it is effective and is administered not longer than 10 days per month, be carried out by the general practitioner or specialist in internal medicine. This is also true for medical prophylactic treatment with dietary supplements, antihypertensive drugs, and tricyclic antidepressants. If this therapy is unsuccessful, prophylactic substances must be used that require more specialized knowledge, which is also reflected in the formal prescription requirements. Neurologists and pain therapists should then be involved in the treatment. This is particularly true for the use of Onabotulinumtoxin A and monoclonal CGRP-(receptor)-antibodies.

Migraine: navigating the hormonal minefield.

Migraine affects 959 million people worldwide,1 with the highest prevalence being in women of childbearing age. The interplay between female hormones and migraine can be a challenging area to navigate since issues relating to pregnancy, contraception and the menopause are often out of the neurology comfort zone. This review aims to help the neurologist to manage women with migraine, from menarche to menopause.

Consensus of the Hellenic Headache Society on the diagnosis and treatment of migraine.

More than 0.6 million people suffer from disabling migraines in Greece causing a dramatic work loss, but only a small proportion of migraineurs attend headache centres, most of them being treated by non-experts. On behalf of the Hellenic Headache Society, we report here a consensus on the diagnosis and treatment of adult migraine that is based on the recent guidelines of the European Headache Federation, on the principles of Good Clinical Practice and on the Greek regulatory affairs. The purposes are three-fold: (1) to increase awareness for migraine in Greece; (2) to support Greek practitioners who are treating migraineurs; and (3) to help Greek migraineurs to get the most appropriate treatment. For mild migraine, symptomatic treatment with high dose simple analgesics is suggested, while for moderate to severe migraines triptans or non-steroidal anti-inflammatory drugs, or both, should be administered following an individually tailored therapeutic strategy. A rescue acute treatment option should always be advised. For episodic migraine prevention, metoprolol (50-200 mg/d), propranolol (40-240 mg/d), flunarizine (5-10 mg/d), valproate (500-1800 mg/d), topiramate (25-100 mg/d) and candesartan (16-32 mg/d) are the drugs of first choice. For chronic migraine prevention topiramate (100-200 mg/d), valproate (500-1800 mg/d), flunarizine (5-10 mg/d) and venlafaxine (150 mg/d) may be used, but the evidence is very limited. Botulinum toxin type A and monoclonal antibodies targeting the CGRP pathway (anti-CGRP mAbs) are recommended for patients suffering from chronic migraine (with or without medication overuse) who failed or did not tolerate two previous treatments. Anti-CGRP mAbs are also suggested for patients suffering from high frequency episodic migraine (≥8 migraine days per month and less than 14) who failed or did not tolerate two previous treatments.

Management of Childhood Migraine by Headache Specialist vs Non-Headache Specialists.

OBJECTIVE: This study aims to compare the management practices of a headache specialist with non-headache specialists in the treatment of children with migraine. The use of appropriate rescue medications and prophylactic agents, application of neuroimaging, and short-term outcomes are compared in children treated by the two groups of physicians. METHODS: A retrospective cohort study was conducted by utilizing the electronic medical records of children 3-18 years of age with migraine, who were evaluated at a tertiary care children's hospital from 2016 to 2018. RESULTS: Of the 849 patients who met the study criteria, 469 children were classified as having chronic migraine or high-frequency episodic migraine and were followed-up on at least 1 occasion by the neurologists. Imaging was obtained in 66.5% of all children with migraine. The headache specialist used 5-HT agonists ("triptans") for migraine management in 56.7% (76/135) of cases compared to non-headache specialists who prescribed them in 28.7% (96/334) of cases (P < .001). Of the children with chronic migraine, the headache specialist evaluated 135 patients while the non-headache specialists treated 334 children. Non-headache specialists prescribed prophylaxis in the form of natural supplements more frequently (63.8% of cases) compared to the headache specialist (38.5% of children) (P < .001). Moreover, prophylaxis with prescription drugs was utilized more often by headache specialist (66.7%) than non-headache specialists (37.4%) (P < .001). CONCLUSIONS: Imaging appears to be commonly recommended by both headache specialists and non-headache specialists in children with migraine. The headache specialist was more likely to use triptans as rescue medications for pediatric migraine. Outcomes in the short-term were not statistically different whether children were being managed by the headache specialist or the non-headache specialists.

The role of oxygen in cluster headache.

High-flow oxygen inhalation is one of the most effective acute treatments for cluster headache. The therapy was first described for the treatment of cluster headache in 1952 by Horton, and has exhibited some advantages and efficacy compared to other acute medicines. The mechanism is not very clear, but some evidence has demonstrated its relationship to the trigeminovascular system and neuroinflammation. High-flow oxygen inhalation via a non-rebreather mask during cluster headache attacks has been widely recommended. Patients with frequent attacks and/or intolerance to drugs may prefer the oxygen treatment.

Patterns of medicinal cannabis use, strain analysis, and substitution effect among patients with migraine, headache, arthritis, and chronic pain in a medicinal cannabis cohort.

BACKGROUND: Medicinal cannabis registries typically report pain as the most common reason for use. It would be clinically useful to identify patterns of cannabis treatment in migraine and headache, as compared to arthritis and chronic pain, and to analyze preferred cannabis strains, biochemical profiles, and prescription medication substitutions with cannabis. METHODS: Via electronic survey in medicinal cannabis patients with headache, arthritis, and chronic pain, demographics and patterns of cannabis use including methods, frequency, quantity, preferred strains, cannabinoid and terpene profiles, and prescription substitutions were recorded. Cannabis use for migraine among headache patients was assessed via the ID Migraine™ questionnaire, a validated screen used to predict the probability of migraine. RESULTS: Of 2032 patients, 21 illnesses were treated with cannabis. Pain syndromes accounted for 42.4% (n = 861) overall; chronic pain 29.4% (n = 598;), arthritis 9.3% (n = 188), and headache 3.7% (n = 75;). Across all 21 illnesses, headache was a symptom treated with cannabis in 24.9% (n = 505). These patients were given the ID Migraine™ questionnaire, with 68% (n = 343) giving 3 "Yes" responses, 20% (n = 102) giving 2 "Yes" responses (97% and 93% probability of migraine, respectively). Therefore, 88% (n = 445) of headache patients were treating probable migraine with cannabis. Hybrid strains were most preferred across all pain subtypes, with "OG Shark" the most preferred strain in the ID Migraine™ and headache groups. Many pain patients substituted prescription medications with cannabis (41.2-59.5%), most commonly opiates/opioids (40.5-72.8%). Prescription substitution in headache patients included opiates/opioids (43.4%), anti-depressant/anti-anxiety (39%), NSAIDs (21%), triptans (8.1%), anti-convulsants (7.7%), muscle relaxers (7%), ergots (0.4%). CONCLUSIONS: Chronic pain was the most common reason for cannabis use, consistent with most registries. The majority of headache patients treating with cannabis were positive for migraine. Hybrid strains were preferred in ID Migraine™, headache, and most pain groups, with "OG Shark", a high THC (Δ9-tetrahydrocannabinol)/THCA (tetrahydrocannabinolic acid), low CBD (cannabidiol)/CBDA (cannabidiolic acid), strain with predominant terpenes ß-caryophyllene and ß-myrcene, most preferred in the headache and ID Migraine™ groups. This could reflect the potent analgesic, anti-inflammatory, and anti-emetic properties of THC, with anti-inflammatory and analgesic properties of ß-caryophyllene and ß-myrcene. Opiates/opioids were most commonly substituted with cannabis. Prospective studies are needed, but results may provide early insight into optimizing crossbred cannabis strains, synergistic biochemical profiles, dosing, and patterns of use in the treatment of headache, migraine, and chronic pain syndromes.

[Therapy of migranes]. / Therapie der Migräne.

In migraine attack treatment analgesics such as nonsteroidal anti-inflammatory drugs and triptans can be utilized. The efficacy of acute attack treatment is relevant to prevent migraine chronification. For prophylactic treatment ß­blockers, tricyclic antidepressants, flunarizine, antiepileptics and onabotulinumtoxin A are available. There is evidence that some other substances (e. g. sartans) are also efficacious in this regard. Furthermore, nondrug approaches are essential in migraine therapy. Early education and prophylactic treatment of patients at risk may prevent from medication overuse headache. Noninvasive neuromodulatory approaches as supraorbital or vagal nerve stimulation are emerging methods for prophylactic treatment. Ongoing clinical trials investigate an oral calcitonin gene-related peptide (CGRP) antagonist for acute treatment and several prophylactic monoclonal CGRP or CGRP receptor-antibodies regarding safety, side effects and efficacy as new therapeutic options.

Prescription Patterns and the Cost of Migraine Treatments in German General and Neurological Practices.

OBJECTIVES: The aim of this study was to analyze prescription patterns and the cost of migraine treatments in general practices (GPs) and neurological practices (NPs) in Germany. METHODS: This study included 43,149 patients treated in GPs and 13,674 patients treated in NPs who were diagnosed with migraine in 2015. Ten different families of migraine therapy were included in the analysis: triptans, analgesics, anti-emetics, beta-blockers, antivertigo products, gastroprokinetics, anti-epileptics, calcium channel blockers, tricyclic antidepressants, and other medications (all other classes used in the treatment of migraine including homeopathic medications). The share of migraine therapies and their costs were estimated for GPs and NPs. RESULTS: The mean age was 44.4 years in GPs and 44.1 years in NPs. Triptans and analgesics were the 2 most commonly prescribed families of drugs in all patients and in the 9 specific subgroups. Interestingly, triptans were more commonly prescribed in NPs than in GPs (30.9% to 55.0% vs. 30.0% to 44.7%), whereas analgesics were less frequently given in NPs than in GPs (11.5% to 17.2% vs. 35.3% to 42.4%). Finally, the share of patients who received no therapy was higher in NPs than in GPs (33.9% to 58.4% vs. 27.5% to 37.9%). The annual cost per patient was €66.04 in GPs and €94.71 in NPs. Finally, the annual cost per patient increased with age and was higher in women and in individuals with private health insurance coverage than in men and individuals with public health insurance coverage. CONCLUSION: Triptans and analgesics were the 2 most commonly prescribed drugs for the treatment of migraine. Furthermore, approximately 30% to 40% of patients did not receive any therapy. Finally, the annual cost per patient was higher in NPs than in GPs.

Treatment of intractable chronic cluster headache by occipital nerve stimulation: a cohort of 51 patients.

BACKGROUND AND PURPOSE: Chronic cluster headache is a rare, highly disabling primary headache condition. When medically intractable, occipital nerve stimulation can offer effective treatment. Open-label series have provided data on small cohorts only. METHODS: We analyzed 51 subjects to evaluate the long-term outcomes of highly intractable chronic cluster headache with occipital nerve stimulation. Patients with intractable chronic cluster headache were implanted with occipital nerve stimulators during the period 2007-2014. The primary endpoint was improvement in daily attack frequency. Secondary endpoints included attack severity, attack duration, quality-of-life measures, headache disability scores and adverse events. RESULTS: We studied 51 patients [35 males; mean age at implant 47.78 (range 31-70) years; mean follow-up 39.17 (range 2-81) months]. Nineteen patients had other chronic headache types in addition in chronic cluster headache. At final follow-up, there was a 46.1% improvement in attack frequency (P < 0001) across all patients, 49.5% (P < 0.001) in those with cluster headache alone and 40.3% (P = 0.036) in those with multiple phenotypes. There were no significant differences in response in those with or without multiple headache types. The overall response rate (defined as at least a 50% improvement in attack frequency) was 52.9%. Significant reductions were also seen in attack duration and severity. Improvements were noted in headache disability scores and quality-of-life measures. Triptan use of responders dropped by 62.56%, resulting in significant cost savings. Adverse event rates were highly favorable. CONCLUSION: Occipital nerve stimulation appears to be a safe and efficacious treatment for highly intractable chronic cluster headache even after a mean follow-up of over 3 years.

Trigeminal Autonomic Cephalalgias in Children and Adolescents: Cluster Headache and Related Conditions.

Cluster headache is a primary headache disorder that can occur in children and adolescents, and is a member of the broader diagnostic group of trigeminal autonomic cephalalgias. It is characterized by repeated attacks typically lasting between 15 and 180 minutes of severe unilateral side-locked headache with cranial autonomic features. Acute treatment of the cluster attack can include the use of triptans or high-flow oxygen. Preventive measures typically start with the use of verapamil. The other trigeminal autonomic cephalalgias, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), and short-lasting unilateral neuralgiform headache with cranial autonomic features (SUNAA), have also been reported in children, and should be considered when the clinical presentation is at all unusual.

Positive effects of the progestin desogestrel 75 µg on migraine frequency and use of acute medication are sustained over a treatment period of 180 days.

BACKGROUND: Premenopausal migraines frequently are associated with fluctuations of estrogen levels. Both, migraine and combined hormonal contraceptives (CHC) increase the risk of vascular events. Therefore progestagen-only contraceptives (POC) are a safer alternative. A previous short-term study demonstrated a positive impact of the oral POC desogestrel on migraine frequency. To study the effect of the POC desogestrel 75 µg on migraine frequency, intensity, use of acute medication and quality of life in a clinical setting over the period of 180 days. METHODS: Patients' charts were screened for women with migraine, who had decided to use desogestrel for contraception. Charts were included, if routinely conducted headache diaries were complete for 90 days before treatment (baseline) and over a treatment period of 180 days. We also report about starters who stopped treatment early, because of adverse events. Baseline data (day 1-90 before treatment) were compared with first and second treatment period (treatment days 1-90 and days 91-180). Quality of life was evaluated using MIDAS questionnaires. RESULTS: Days with migraine (5.8 vs 3.6), with any kind of headache (9.4 vs 6.6), headache intensity (15.7 vs 10.7), days with severe headache (5.4 vs 2.4) and use of triptans (12.3 vs7.8) were significantly reduced after 180 days. MIDAS score and grade improved significantly. CONCLUSION: Contraception with desogestrel 75 µg resulted in a significantly improved quality of life and a reduction of migraine days over the observation period of 180 days. A clinically meaningful 30% reduction in pain was observed in 25/42 (60%) participants. For counselling reasons it is of importance, that the major reduction in migraine frequency occured during the initial 90 days, however further improvement occurs with longer duration of use. Prospective studies are needed to confirm these results.
