Abstract
Chronic headaches are a major source of morbidity in the pediatric population, affecting physical function, school attendance, social capacity, mood, and sleep. In adults, repetitive sphenopalatine ganglion (SPG) blockade has been studied as a preventive treatment for chronic migraines. This case series aims to evaluate the SPG block for the preventive treatment of chronic daily headache (CDH) in adolescents. We prospectively evaluated 17 adolescents (14 females, 14 ± 1 year) with CDH not responding to cognitive behavioral therapy (CBT), physiotherapy, and standard medications. Each patient received 10 SPG blocks (two blocks/week) using the Tx360® device. At the end of treatment, 10 patients (59%) reported a Patient's Global Impression of Change (PGIC) score ≥ 67%, and 3 months after the end of treatment, nine patients (53%) sustained a PGIC ≥ 67%. There was also a statistically significant reduction in the depression subscale of the Revised Children's Anxiety and Depression Scale (RCADS) at the end of treatment and 3 months post-treatment compared with baseline. The procedure was well tolerated with no adverse effects. In our study, the use of repeat SPG blockade was associated with sustained benefits on the PGIC and the depression subscale of the RCADS when used as preventive headache treatment in adolescents with refractory CDH.

Abstract
Background Medication overuse headache (MOH) is one of the highly disabling headache disorder and affects about 1% of the population of the world. It is associated with the development of headache for 15 days or more, with consumption of acute symptomatic medications for 10-15 days (depending on the class of drug, like, simple analgesics, triptans, and opioids) in a month, used for relief of headache for three or more months, in a known patient of primary headache disorder. Objective The aim of this study was to review the topic of MOH and present the details of this disorder with an emphasis on recent updates in the field of pathophysiology and treatment. Material and Methods Literature search was performed in the PubMed/MEDLINE and Cochrane database with appropriate keywords and relevant full-text articles were reviewed for writing this article. Results Over the years, the concept of MOH has evolved, although the exact pathophysiology is still being explored. In a susceptible individual interplay of genetics, change in pain pathways, changes in areas of the brain associated with the perception of pain, and changes in the neurotransmitters have been implicated. It has to be differentiated from other secondary chronic daily headache disorders, by a careful history, targeted examination, details of intake of medications. Treatment predominantly involves patient education, removal of the offending agent, and initiation of prophylactic medications for primary headache disorder in the outpatient or inpatient services. Conclusions MOH is a secondary headache disorder, which should be considered in any chronic headache patient. There are various pathophysiological mechanisms attributed to its development. Management includes educating the patients about the disorder, detoxification, and prophylactic therapy.

Abstract
Chronic pain syndromes present a subversion of both functional and structural nociceptive networks. We used transcranial magnetic stimulation (TMS) to evaluate changes in cortical excitability and plasticity in patients with chronic migraine (CM) treated with botulinum neurotoxin type A (BoNT/A). We enrolled 11 patients with episodic migraine (EM) and 11 affected by CM. Baseline characteristics for both groups were recorded using single- and paired-pulse TMS protocols. The same TMS protocol was repeated in CM patients after four cycles of BoNT/A completed in one year. At baseline, compared with EM patients, patients with CM had a lower threshold in both hemispheres (right hemisphere: 46% ± 7.8 vs. 52% ± 4.28, p = 0.03; left hemisphere: 52% ± 4.28 vs. 53.54% ± 6.58, p = 0.02). In EM, paired-pulse stimulation elicited a physiologically shaped response, whereas in CM, physiological intracortical inhibition (ICI) between 1 and 3 ms intervals was absent at baseline. On the contrary, increasing intracortical facilitation (ICF) was observed for all interstimulus intervals (ISIs). In CM, cortical excitability was partially reduced after BoNT/A treatment, along with a significant decrease observed in MIDAS score (from 20.7 to 9.8; p = 0.008). The lower motor threshold in CM reflects a higher cortical hyperexcitability. The lack of physiological ICI in CM could indicate sensitisation of the trigeminovascular system. Although reduced, this type of response is still observable after treatment, despite a marked clinical improvement. Our study suggests a long-term alteration of cortical plasticity due to chronic pain.

Abstract
Introduction. Our aim was to investigate the clinical features of primary new daily persistent headache (NDPH) in a cohort of paediatric patients. Methods. We reviewed the data of patients with persistent daily headache, attending the Headache Centre of Bambino Gesù Children from the January 2009. The ICHD-III criteria were used for diagnosis. Statistical analysis was conducted to study possible correlations between NDPH and population features (age and sex), NDPH and headache qualitative features, and NDPH and response to pharmacological therapies. Results. We included 46 subjects with NDPH. The features of pain more closely resembled those of migraine than to those of tension-type headache (62 vs. 38%). The NDPH patients showed nausea and vomiting less frequently than migraine ones (28.6 vs. 48.2%, p < 0.01). A total of 75% of NDPH patients experienced an onset of the symptoms in the winter months (November to February) (p < 0.01). NDPH was less common in very young children under 10 years of age. Almost 58% of NDPH patients received pharmacological therapy and the most used drug was amitriptyline. A reduction of attacks by at least 50% in a month was detected in 30.6% of patients. Conclusions. NDPH can be very disabling and correlates with seasonal factors. Although long term pharmacological therapy is recommended, considering the long duration that this headache can have, there are no data supporting the treatment choice.

Abstract
The hanger reflex is a phenomenon characterized by the involuntary rotation of the head when a wire hanger is worn around the head such that a force is applied to the frontal temporal area by the longer side of the hanger. The application of a shearing force on the skin is thought to be the cause of this phenomenon. Attempts have been made to treat cervical dystonia using equipment designed to induce the hanger reflex. This reflex may have implications in the treatment of headaches, cervical pain, and adhesive capsulitis. The hanger reflex is seen not only in the head region but is also in other parts of the body. Thus, it could be used in the treatment of systemic dystonias. The hanger reflex may help develop inexpensive and non-invasive treatment for dystonia or other neurological diseases and is expected to be the focus of research in the future.

Abstract
OBJECTIVES To evaluate the cost, accessibility and patient satisfaction implications of two clinical pathways used in the management of chronic headache. INTERVENTION Management of chronic headache following referral from Primary Care that differed in the first appointment, either a Neurology appointment or an MRI brain scan. DESIGN AND SETTING A pragmatic, non-randomised, prospective, single-centre study at a Central Hospital in London. PARTICIPANTS Adult patients with chronic headache referred from primary to secondary care. PRIMARY AND SECONDARY OUTCOME MEASURES Participants' use of healthcare services and costs were estimated using primary and secondary care databases and questionnaires quarterly up to 12 months postrecruitment. Cost analyses were compared using generalised linear models. Secondary outcomes assessed: access to care, patient satisfaction, headache burden and self-perceived quality of life using headache-specific (Migraine Disability Assessment Scale and Headache Impact Test) and a generic questionnaire (5-level EQ-5D). RESULTS Mean (SD) cost up to 6 months postrecruitment per participant was £578 (£420) for the Neurology group (n=128) and £245 (£172) for the MRI group (n=95), leading to an estimated mean cost difference of £333 (95% CI £253 to £413, p<0.001). The mean cost difference at 12 months increased to £518 (95% CI £401 to £637, p<0.001). When adjusted for baseline and follow-up imbalances between groups, this remained statistically significant. The utilisation of brain MRI improved access to care compared with the Neurology group (p<0.001). Participants in the Neurology group reported higher levels of satisfaction associated with the pathway and led to greater change in care management. CONCLUSION Direct referral to brain MRI from Primary Care led to cost-savings and quicker access to care but lower satisfaction levels when compared with referral to Neurology services. Further research into the use of brain MRI for a subset of patient population more likely to be reassured by a negative brain scan should be considered. TRIAL REGISTRATION NUMBER NCT02753933.

Abstract
BACKGROUND Post dural puncture headache (PDPH) is a known complication which may occur in the setting of patients undergoing lumbar punctures (LP) for diagnostic or therapeutic purposes. The gold standard for treating a PDPH is an epidural blood patch (EBP). There have been few publications evaluating the long-term outcomes of PDPH treated with EBP. The aim of this pilot study was to examine the incidence of chronic headaches in dural puncture patients who received EBP versus those who did not. METHODS A retrospective case control study was performed at a single large center institution. Forty-nine patients who had intentional dural puncture were identified on chart review and completed a survey questionnaire via phone interview: twenty-six of these patients required a subsequent EBP, while twenty-three did not. The primary outcomes were the development and prevalence of chronic headaches after the procedures. There was no statistically significant difference in the prevalence of current headaches between the EBP group and Non-EBP group (54% vs. 52% p = 0.91). There were no significant differences in the rates of severity and descriptive qualities of headache between the EBP and non-EBP groups. There was higher incidence of tinnitus in the PDPH patients. SUMMARY This pilot study demonstrates that patients who received an EBP for treatment of a PDPH following LP are no more likely to experience chronic headaches compared to patients who do not receive an EBP. However, both the EBP group and Non-EBP group had high incidence of chronic headaches which may be related to dural puncture or a baseline trait of this cohort given the recall bias. There is a suggestion that tinnitus could be a long-term residual symptom of PDPH treated with EBP.

Abstract
INTRODUCTION Chronic headaches are poorly diagnosed and managed and can be exacerbated by medication overuse. There is insufficient evidence on the non-pharmacological approaches to helping people living with chronic headaches. METHODS AND ANALYSIS Chronic Headache Education and Self-management Study is a pragmatic randomised controlled trial to test the effectiveness and cost-effectiveness of a self-management education support programme on top of usual care for patients with chronic headaches against a control of usual care and relaxation. The intervention is a 2-day group course based on education, personal reflection and a cognitive behavioural approach, plus a nurse-led one-to-one consultation and follow-up over 8 weeks. We aim to recruit 689 participants (356 to the intervention arm and 333 to the control) from primary care and self-referral in London and the Midlands. The trial is powered to show a difference of 2.0 points on the Headache Impact Test, a patient-reported outcome measure at 12 months post randomisation. Secondary outcomes include health related quality of life, self-efficacy, social activation and engagement, anxiety and depression and healthcare utilisation. Outcomes are being measured at 4, 8 and 12 months. Cost-effectiveness will be expressed in terms of incremental cost per quality-adjusted life year gained. ETHICS AND DISSEMINATION This trial will provide data on effectiveness and cost-effectiveness of a self-management support programme for chronic headaches. The results will inform commissioning of services and clinical practice. North West - Greater Manchester East Research Ethics Committee have approved the trial. The current protocol version is 3.6 date 7 March 2019. TRIAL REGISTRATION NUMBER ISRCTN79708100.

Abstract
OBJECTIVES The primary outcome of this study was to assess the efficacy and safety of preventive treatment with amitriptyline on headache frequency and severity after mild traumatic brain injury (mTBI). BACKGROUND Despite the fact that headache is the most common and persistent physical symptom after TBI, there has been little research on the longitudinal course or pharmacologic treatment of this disorder. Of those who have headache after injury, about 60% continue to complain of headache at 3 months post injury, with higher levels of disability than those without headache. There have been no prospective, randomized, controlled trials of a pharmacologic agent for headache after TBI. Additionally, a brain-injured population may be more susceptible to side effects of medication. DESIGN This is a single-center phase II trial of amitriptyline to prevent persistent headache after an mTBI. Medication dose was gradually increased from 10 to 50 mg daily. RESULTS Fifty participants were enrolled and 33 who completed the 90-day assessment were included in the final analysis. In order to detect a possible cognitive impact of the study drug, 24 participants were randomly assigned to start amitriptyline immediately after study enrollment and 26 were assigned to start 30 days after enrollment. Forty-nine percent (18/37) of those assigned to take medication took none throughout the study period, with less compliance in younger participants with mean ages of 32.7 in those who did not take any medication, 33.4 who were less than 80% compliant, and 42.3 who were compliant (P = .013). Compliance in keeping a daily headache diary was low, with 29/50 participants (58%) meeting daily entry completion, and only 10 participants maintaining 100% diary completion. No differences were found between those who started medication immediately vs at day 30 in headache frequency or severity. CONCLUSIONS While headache is the most common symptom following mTBI, current evidence does not support a specific treatment. No differences were noted in headache frequency compared to our prior study. However, the current sample had significantly lower headache severity (15% vs 36% with pain rating of 6 or above, P = .015) compared to our prior study. Our current study was not able to determine whether there is any benefit for the use of amitriptyline as a headache preventive because of difficulty with study recruitment and compliance. The challenges with recruitment and retention in the mTBI population were instructive, and future research in this area will need to identify strategies to improve recruitment, diary compliance, and medication adherence in this population.

Abstract
Background: Transverse sinus stenosis is a common brain MRI finding in chronic migraine (CM) and chronic tension-type headache (CTTH) patients in clinical practice; however, its clinical and diagnostic role is unclear. The aim of the study is to determine the frequency of transverse sinus stenosis in these headache patients resistant to preventive treatments and to verify whether this is a useful finding for identifying patients with intracranial hypertension. Methods: This is an observational study. Patients with refractory CM and CTTH underwent a 3T-magnetic resonance venography (MRV) before cerebrospinal fluid (CSF) opening pressure measurement. Transverse sinus stenosis was determined using the combined conduit score. Patients with opening pressure >200 repeated MRV study 1 month after CSF withdrawal to evaluate changes in neuroimaging findings. Results: We analyzed MRV studies of 40 patients (32 F, 8 M; mean age, 49.4 ± 10.8; mean body mass index, 26.7 ± 6.4; 39 CM and 1 CTTH with concomitant episodic migraine). Nineteen cases (47.5%) had evidence of transverse sinus stenosis: bilateral in seven patients (17.5%) and unilateral in 12 cases (30%). No statistically significant differences in transverse sinus stenosis distribution were found between patients with opening pressure <200 mmH2O and those with opening pressure >200 mmH2O. On Spearman bivariate test, there was no correlation between opening pressure and combined conduit score. No changes in neuroimaging findings were found 1 month after CSF withdrawal. Conclusion: Transverse sinus stenosis is a frequent radiological finding (47.5%) in CM and CTTH patients refractory to preventive treatments. However, this finding is not suggestive of intracranial hypertension. Whether transverse sinus stenosis may be a possible risk factor for chronic headache or a comorbidity needs to be evaluated in larger epidemiological studies.

Abstract
Background: Chronic headache is one of the most common pain conditions, often leading to symptomatic drug overuse. The aim of this study was to provide data on symptomatic drug consumption in an Italian outpatient population and to describe how the clinical picture of headache may change after headache experts take charge of the care of affected individuals. Methods: A total of 199 adults complaining of chronic headache were recruited through 32 pharmacies in the Pavia health district. Participants underwent four evaluations: a baseline assessment (T0) and three follow-up evaluations performed by a neurologist at 3, 6, and 12 months (T3, T6, and T12, respectively). On each occasion, they underwent a complete neurological assessment and received therapeutic adjustments to achieve better management of their headache. Results: On the basis of a preliminary telephone interview, the prevalence rates of chronic headache and medication overuse headache (MOH) were 16 and 12%, respectively. At 12 months of follow-up, we observed a significant decrease in the frequency of attacks (T0: 9 ± 9/month vs. T12: 2 ± 2/month; p < 0.001), in the number of days/month with headache (T0: 11 ± 9 vs. T12: 4 ± 4; p < 0.001) and in single attack duration (T0: 34 ± 30 h vs. T12: 10 ± 19 h; p < 0.001). Careful headache management resulted in a significant decrease in analgesic consumption (T0: 12 ± 16 vs. T12: 4 ± 6 doses/month; p = 0.014) and a significant increase in quality of life, measured using the Migraine Disability Assessment Scale (MIDAS) and Headache Under-Response to Treatment (HURT) scales (p < 0.001). Conclusions: Headache management by a specialist is more effective than self-treatment, resulting in an overall benefit for headache patients.

Abstract
Introduction: Chronic headaches are not a rare condition in children and adolescents with negative effects on their quality of life. Our aims were to investigate the clinical features of chronic headache and usefulness of the International Classification of Headache Disorders 3rd edition (ICHD 3) criteria for the diagnosis in a cohort of pediatric patients. Methods: We retrospectively reviewed the charts of patients attending the Headache Center of Bambino Gesù Children and Insubria University Hospital during the 2010–2016 time interval. Statistical analysis was conducted to study possible correlations between: (a) chronic primary headache (CPH) and demographic data (age and sex), (b) CPH and headache qualitative features, (c) CPH and risk of medication overuse headache (MOH), and (d) CPH and response to prophylactic therapies. Moreover, we compared the diagnosis obtained by ICHD 3 vs. ICHD 2 criteria Results: We included 377 patients with CPH (66.4% females, 33.6% males, under 18 years of age). CPH was less frequent under 6 years of age (0.8%; p < 0.05) and there was no correlation between age/sex and different CPH types. The risk to develop MOH was higher after 15 years of age (p < 0.05). When we compared the diagnosis obtained by ICHD 2 and ICHD 3 criteria we found a significant difference for the undefined diagnosis (2.6% vs. 7.9%; p < 0.05), while the diagnosis of probable chronic migraine was only possible by using the ICHD2 criteria (11.9% of patients; p < 0.05). The main criterion which was not satisfied for a definitive diagnosis was the duration of the attacks less than 2 h (70% of patients younger than 6 years; p < 0.005). Amitriptyline and topiramate were the most effective drugs (p < 0.05), although no significant difference was found between them (p > 0.05). Conclusion: The ICHD 3 criteria show limitations when applied to children under 6 years of age. The risk of developing MOH increases with age. Although our “real word” study shows that amitriptyline and topiramate are the most effective drugs regardless of the CPH type, the lack of placebo-controlled data and the limited follow-up results did not allow us to conclude about the drug efficacy.

Abstract
Objective: To identify the pressure-related features of isolated cerebrospinal fluid hypertension (ICH) in order to differentiate headache sufferers with ICH from those with primary headache disorder. Methods: In this prospective study, patients with refractory chronic headaches and suspected of having cerebrospinal fluid-pressure elevation without papilledema or sixth nerve palsy, together with controls, underwent 1-h lumbar cerebrospinal fluid pressure monitoring via a spinal puncture needle. Results: We recruited 148 consecutive headache patients and 16 controls. Lumbar cerebrospinal fluid pressure monitoring showed high pressure and abnormal pressure pulsations in 93 (63 %) patients with headache: 37 of these patients with the most abnormal pressure parameters (opening pressure above 250 mm H2O, mean pressure 301 mm H2O, mean peak pressure 398 mm H2O, and severe abnormal pressure pulsations) had the most severe headaches and associated symptoms (nocturnal headache, postural headache, transient visual obscuration); 56 patients with the less abnormal pressure parameters (opening pressure between 200 and 250 mm H2O, mean pressure 228 mm H2O, mean peak pressure 316 mm H2O, and abnormal pressure pulsations) had less severe headaches and associated symptoms. Conclusions: Nocturnal and postural headache, and abnormal pressure pulsations are the more common pressure-related features of ICH in patients with chronic headache. Abnormal pressure pulsations may be considered a marker of ICH in chronic headache.

Abstract
OBJECTIVES To investigate associations between different types of headaches and shift work. DESIGN, PARTICIPANTS AND OUTCOME MEASURES Nurses with different work schedules (day work, two-shift rotation, night work, three-shift rotation) participated in a cohort study with annual surveys that started in 2008/2009. In 2014 (wave 6), a comprehensive headache instrument was included in the survey, in which 1585 nurses participated. Headaches were assessed according to the International Classification of Headache Disorders IIIb. Frequent headache (≥1 day per month), migraine, tension-type headache, chronic headache (headache >14 days per month) and medication-overuse headache (chronic headache + acute headache medication ≥10 days last month) comprised the dependent variables. Adjusted (for sex, age, percentage of full-time equivalent, marital status, children living at home) logistic regression analyses were conducted with work schedule, number of night shifts worked last year, number of quick returns (<11 hours in-between shifts) last year, shift work disorder and insomnia disorder as predictors. RESULTS Frequent headache, migraine and chronic headache were associated with shift work disorder (OR 2.04, 95% CI 1.62 to 2.59; 1.60, 1.21 to 2.12; 2.45, 1.25 to 4.80, respectively) and insomnia disorder (OR 1.79, 95% CI 1.43 to 2.23; 1.55, 1.18 to 2.02; 3.03, 1.54 to 5.95, respectively), but not with work schedule, number of night shifts or number of quick returns. Tension-type headache was only associated with >20 night shifts last year (OR 1.41, 95% CI 1.07 to 1.86). Medication-overuse headache was only associated with insomnia disorder (OR 7.62, 95% CI 2.48 to 23.41). CONCLUSIONS We did not find any association between different types of headaches and work schedule. However, tension-type headache was associated with high number of night shifts. Nurses with sleep disorders (insomnia disorder and shift work disorder) reported higher prevalence of frequent headaches, migraine, chronic headache and medication-overuse headache (only insomnia) compared with nurses not having insomnia disorder and shift work disorder, respectively.

Abstract
Irritable bowel syndrome (IBS) is one of the most debilitating and common gastrointestinal disorders; nevertheless, its pathophysiology is still unclear. It affects 11% of the world's population, and is characterized by alternating periods of pain and/or motility disorders with periods of remission and without any evidence of any structural and functional organic variation. It has been recently proposed that an altered contractile ability of the diaphragm muscle might adversely influence intestinal motility. The text reviews the diaphragm's functions, anatomy, and neurological links in correlation with the presence of chronic symptoms associated to IBS, like chronic low back pain, chronic pelvic pain, chronic headache, and temporomandibular joint dysfunction, vagus nerve inflammation, and depression and anxiety. The interplay between an individual's breath dynamic and intestinal behaviour is still an unaddressed point in the physiopathology of IBS, and the paucity of scientific studies should recommend further research to better understand the importance of breathing in this syndrome.

Abstract
Background: To determine the prevalence of Idiopathic intracranial hypertension without papilledema (IIHWOP) testing revised diagnostic criteria by Friedman in refractory chronic headache (CH) patients. Methods: This is a prospective observational study. Each patient underwent ophthalmologic evaluation and Optical Coherence Tomography; brain magnetic resonance venography (MRV) and a lumbar puncture (LP) with opening pressure (OP) measurement. CSF withdrawal was performed in patients with CSF OP > 200 mmH20. IIHWOP was defined according Friedman's diagnostic criteria. Effect of CSF withdrawal was evaluated clinically in a 6-month follow-up and with a MRV study at 1 month. Results: Forty-five consecutive patients were enrolled. Five were excluded due to protocol violations. Analyses were conducted in 40 patients (32 F, 8 M; mean age 49.4 ± 10.8). None had papilledema. Nine patients (22.5%) had OP greater than 200 mmH2O, two of them above 250 mmH2O. Two (5%) had neuroimaging findings suggestive of elevated intracranial pressure. One of them (2.5%) met the newly proposed diagnostic criteria by Friedman for IIHWOP. After CSF withdrawal seven (77.8%) of the nine patients improved. No changes in neuroimaging findings were found. Conclusions: We found a low prevalence (2.5%) of IIHWOP in refractory CH patients according to current diagnostic criteria. In agreement with Friedman's criteria, our results confirm that a diagnosis of IIHWOP should be based on CSF OP and the combination of neuroradiological findings. However, where to set the CSF OP upper limit in IIHWOP needs further field testing. Although IIHWOP is a rare clinical condition, it should be considered and treated in refractory CH patients.

Abstract
OBJECTIVES People with migraine and tension-type headache (TTH) have psychiatric comorbidities. We aimed to test differences in mental health constructs by type and frequency of primary headache and associated pain sensitivity. MATERIALS AND METHODS Data on headache features, neuroticism (Eysenck Personality Questionnaire) and depression (Major Depression Inventory) were obtained from 547 individuals classified into chronic (≥15) or episodic (<15 headache days/month) and into pure migraine (n=43), pure tension type headache (TTH, n=97), migraine and TTH (n=83) and no headache diagnosis (controls, n=324) groups. A pericranial total tenderness score (TTS) and pressure pain thresholds (PPTs) were measured. Differences in mental health constructs were examined by headache frequency and type using generalized linear mixed models adjusting for sociodemographic covariates. RESULTS Depression scores were highest among people with chronic headache, lower in those with episodic headache, and lowest in controls. The chronic and episodic headache groups had higher neuroticism scores than controls. Mental health construct scores were highest for the migraine and TTH group and lowest in the control group. TTS and cephalic PPTs were correlated with neuroticism and depression and were higher in the chronic headache group compared to the no headache group even when adjusted for neuroticism and depression. CONCLUSIONS Neuroticism and depression scores are associated with headache frequency (chronic vs episodic) and are highest for migraine and TTH followed by pure TTH then migraine. Mental health constructs were correlated with but did not influence differences in TTS and PPTs between headache groups.

Abstract
OBJECTIVES To investigate predictors for successful treatment outcome after a brief intervention (BI) for medication-overuse headache (MOH). MATERIALS AND METHODS This study evaluated predictors of successful withdrawal among patients initially participating in a pragmatic cluster-randomized controlled trial with single crossover in Norwegian general practice (the BIMOH study). BI (early or after crossover) was compared to business as usual (BAU) for the treatment of MOH. Patients were followed up 3 months after the BI. RESULTS In total, 46 patients had the chance to receive the BI (24 early and 22 after crossover) and were included in the predictor analyses. The mean reduction in headache and medication days/month from baseline for the BI was 6.9 (95% CI: 4.8-9.1) and 10.9 (8.1-13.6). The mean percentage reduction in headache and medication days was 30.5% (21.4-39.7) and 50.4% (39.5-61.3). Only five patients started prophylactic medication. Neither age, gender, co-occurrence of migraine, main type of overused drug at baseline nor Severity of Dependence Scale score at baseline predicted successful withdrawal in the prespecified analyses. Headache days/month and medication use at baseline were significant predictors in exploratory analyses with more headache and medication days predicting worse outcome. CONCLUSIONS Brief intervention for MOH is a simple and effective intervention in primary care. As the only identified predictors were frequency of headache and medication use, we conclude that treatment for all MOH patients should be attempted in primary care before referral. A raised awareness of MOH is important, as the condition is highly preventable and treatable. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT01314768.

Abstract
BACKGROUND Posttraumatic headache (PTH) occurs in up to 82% of patients with traumatic brain injury (TBI). Posttraumatic stress disorder (PTSD) occurs in 39% of those with PTH. This study evaluates whether PTSD affects PTH disability. METHODS Eighty-six patients with TBI were prospectively evaluated in a secondary care trauma center. Headache disability was assessed using the Headache Impact Test version 6 and signs indicative of PTSD using the PTSD Check List Civilian version. RESULTS Increased PTSD-type symptoms were significantly associated with increased headache disability (p<0.001), as were employment status and loss of consciousness (p=0.049 and 0.016, respectively). Age was negatively correlated with headache disability (Spearman's correlation rho=0.361, p=0.001). CONCLUSION Increased severity of PTSD-type symptoms is significantly associated with increased headache disability in patients with chronic PTH. Managing PTSD symptoms in patients with chronic PTH may facilitate headache management.

Abstract
RATIONALE Idiopathic hypertrophic pachymeningitis (IHP) is a rare condition, characterized by a chronic fibrosing inflammatory process usually involving either the intracranial or spinal dura mater, but rarely both. Here, we report a rare case of IHP affecting both the intracranial and spinal dura mater. We also discussed the diagnosis, management, and outcome of IHP. PATIENT CONCERNS We reviewed the case of a 60-year-old woman presenting with chronic headache, multiple cranial nerve palsies and gait disturbance. Magnetic resonance imaging (MRI) of her head revealed thickened and contrast-enhanced dura in the craniocervical region as well as obstructive hydrocephalus and cerebellar tonsillar herniation. The patient had a suboccipital craniectomy and posterior decompression through C1 plus a total laminectomy. The dura was partially resected to the extent of the bony decompression, and a duroplasty was performed. DIAGNOSES Microscopic examination of the surgically resected sample showed chronic inflammatory changes, lymphoplasmacytic cell infiltration, fibrous tissue hyperplasia, and hyaline degeneration. Blood tests to evaluate the secondary causes of hypertrophic pachymeningitis (HP) were unremarkable. INTERVENTIONS Steroid was used to treat suspected IHP. OUTCOMES Postoperatively, the patient showed gradual improvement in her headache, glossolalia, and bucking. Prior to discharge, a follow-up MRI showed improvement of the dura mater thickening. LESSONS IHP is a chronic inflammatory disorder of the dura mater that usually causes neurological deficits. Clinical manifestations of IHP, MRI findings, and laboratory abnormalities are the essential components for making an accurate diagnosis. When the radiological or laboratory evaluation is uncertain, but neurological deficits are present, a prompt surgical approach should be considered. Postoperative steroid therapy and close observation for recurrence are necessary to ensure a good long-term outcome.

Abstract
OBJECTIVE To evaluate the efficacy of an intensive outpatient program designed to improve functioning and reduce psychological impairment in chronic headache patients. BACKGROUND Chronic headaches, occurring 15 or more days per month, for three or more months, may arise from multiple International Classification of Headache Disorders diagnoses: Chronic Migraine, Chronic Tension Type Headache, New Daily Persistent Headache, Chronic Post Traumatic Headaches, and Medication Overuse Headache. Several interdisciplinary programs that treat patients with chronic headaches have reported decreases in headache frequency. This study sought to evaluate the effect of a 3 week interdisciplinary treatment program for patients with chronic headache disorders on headache severity, functional status, and psychological impairment. METHODS Subjects were 379 patients admitted to an outpatient chronic headache treatment program. Assessments of headache severity, psychological status, and functional impairment were completed by 371 (97.8%) of these at the time of admission. At discharge, 340 subjects (89.7%) provided assessment data, and 152 (40.1%) provided data at 1-year follow-up. RESULTS Subjects' mean ratings on a 0-10 scale for their headache pain in the prior week declined, and these improvements were maintained at follow-up. (Estimated marginal means on a 0-10 scale for Average pain: admission 6.1, discharge 3.5, follow-up 3.3; for Least pain: admission 3.2; discharge 1.5; follow-up 1.3; for Worst pain: admission 8.2; discharge 6.4; follow-up 5.7), and similar results were found for current pain (admission 4.7; discharge 2.8; follow-up 2.4): Measures of functional impairment also improved following treatment, and these gains were maintained at 12 month follow up (Estimated marginal mean Headache Impact Test-6 score: admission 66.1, discharge 55.4, follow-up 51.9; Estimated marginal mean Pain Disability Index score: admission 36.2, discharge 14.1, follow-up 11.6). As measured by the Depression, Anxiety and Stress Scale, anxiety and reactivity to stress decreased following treatment, and remained improved at follow-up (Estimated marginal mean score for Anxiety: admission 8.7, discharge 5.2, follow-up 4.4; Estimated marginal mean score for stress: admission 14.9, discharge 7.2, follow-up 7.6). Depression decreased with treatment, but while 1-year follow-up depression scores remained significantly lower than at admission, they were also significantly higher than at discharge (Estimated marginal means: admission 13.3, discharge 4.1, follow-up 6.6). CONCLUSIONS The study supports the efficacy of the treatment model. Limitations of the study and suggestions for future research are also discussed.

Abstract
This study aims to characterize the psychological wellbeing of chronic headache (CH) patients, to identify cortical structural abnormalities and any associations of those abnormalities with resting state functional connectivity (rsFC), and to determine whether such rsFC abnormality is specific to CH patients. Compared with healthy controls (CONCH ), CH patients suffered from mild depression, sleep disturbances, and relatively poor quality of life. CH patients also exhibited widespread cortical thickness (CT) abnormalities in left premotor (BA6), right primary somatosensory (S1) and right prefrontal (BA10) cortices, as well as in regions of default mode and executive control networks. Using cortical regions with thickness abnormality as seeds, we found cortical region pairs showed strengthened rsFC in CH patients. Using the same seeds, rsFC analysis from chronic low back pain (CLBP) patients and their controls (CONCLBP ) identified abnormalities in non-overlapping cortical region pairs. Direct comparison of rsFC between CH and CLBP patients revealed significantly differences in thirteen cortical region pairs, including the four identified in CH and CONCH comparison. Across all three groups (CH, CLBP and CON), the rsFC between left multisensory association area (BA39) and left posterior cingulate cortex (BA23) differed significantly. Eight regions showed CT abnormality in CLBP patients, two of which overlapped with those of CH patients. Our observations support the notion that CH and CLBP pain are pathological conditions, under which the brain develops distinct widespread structural and functional abnormalities. CH and CLBP groups share some similar structural abnormalities, but rsFC abnormalities in several cortical region pairs appear to be pathology-specific.

Abstract
Medication-overuse headache (MOH) is a debilitating condition in which frequent and prolonged use of medication for the acute treatment of pain results in the worsening of the headache. The purpose of this paper is to review the most recent literature on MOH and discuss future avenues for research. MOH accounts for a substantial share of the global burden of disease. Prevalence is often reported as 1-2% but can be as high as 7% overall, with higher proportions among women and in those with a low socioeconomic position. Management consists of withdrawing pain medication, focusing on prophylactic and nonmedical treatments, and limiting acute symptomatic medication. Stress reduction and lifestyle interventions may support the change towards rational pain medication use. Support, follow up, and education are needed to help patients through the detoxification period. There is fertile ground for research in MOH epidemiology, pathophysiology, and neuroimaging. Randomized and long-term follow-up studies on MOH treatment protocols are needed. Further focused research could be of major importance for global health.

Abstract
BACKGROUND AND PURPOSE Medication-overuse headache (MOH) is common in the general population. Detoxification is the general treatment principle for MOH. The present paper is based on a study of a brief intervention (BI) for MOH in primary care. New data on headache disability and the Hospital Anxiety and Depression Scale (HADS) for MOH patients compared to population controls with and without chronic headache are presented and compared to previously published main outcome data. METHODS This was a double-blind pragmatic cluster randomized controlled trial carried out amongst 50 general practitioners in Norway. The BI was compared to business as usual (BAU) and population controls, and patients were followed up after 3 months. Primary outcomes were headache and medication days per month after 3 months. Headache disability and HADS were also measured as secondary outcomes. RESULTS Sixty MOH patients and 40 population controls were included. BI was significantly better than BAU after 3 months regarding primary outcomes. Non-intervention population controls did not change. The MOH patients had significantly higher headache disability and anxiety scores than the population controls. CONCLUSIONS Patients with MOH are a highly disabled group where anxiety and depression are important comorbidities. Detoxification of MOH by a BI in primary care is effective and has potential for saving resources for more treatment-resistant cases in neurologist care.
