RESUMEN

BACKGROUND: Trigeminal neuralgia (TN) is a severe, disabling form of painful cranial neuropathy. Even though TN has a typical clinical picture, diagnosis it is often missed or delayed in clinical practice. In order to investigate the occurrence of diagnostic and therapeutic errors in TN, we studied 102 patients suffering from TN recruited through a multicentric survey. METHODS: We performed a Pubmed database search on errors and pittfalls in TN diagnosis and management. Then, patients with TN were consecutively enrolled in the period from February 2017 to October 2019, by several European Headache Centers participating in the study, following a call of the Headache and Pain Scientific Panels of the European Academy of Neurology (EAN). Diagnosis of Classical Trigeminal Neuralgia (CTN) was made according to the International Headache Society (IHS) criteria (Tölle et al., Pain Pract 6:153-160, 2006). All the patients were evaluated using telephone/frontal interviews conducted by headache/pain specialists using an ad hoc questionnaire. RESULTS: A number of 102 patients were recruited, mostly females (F:M ratio 2.64:1). Eighty-six percent of the patients consulted a physician at the time they experienced the first pain attacks. Specialists consulted before TN diagnosis were: primary care physicians (PCP) (43.1%), dentists (in 30.4%), otorhinolaryngologists (3.9%), neurosurgeons (3.9%), neurologists or headache specialists (14.7%), others (8%). The final diagnosis was made mainly by a neurologist or headache specialist (85.3%), and the mean interval between the disease onset and the diagnosis made by a specialist was 10.8 ± 21.2 months. The "diagnostic delay" was 7.2 ± 12.5 months, and misdiagnoses at first consultation were found in 42.1% of cases. Instrumental and laboratory investigations were carried out in 93.1% of the patients before the final diagnosis of TN. CONCLUSION: While TN has typical features and it is well defined by the available international diagnostic criteria, it is still frequently misdiagnosed and mistreated. There is a need to improve the neurological knowledge in order to promptly recognize the clinical picture of TN and properly adhere to the specific guidelines. This may result in a favorable outcome for patients, whose quality of life is usually severely impaired.

RESUMEN

BACKGROUND: The frequent use of medication to treat migraine attacks can lead to an increase in migraine frequency and is called medication-overuse headache (MOH). METHODS: Based on the available literature in this guideline, the first step in patient management is education and counselling. RESULTS: Patients with MOH should be managed by a multidisciplinary team of neurologists or pain specialists and behavioral psychologists. Patients in whom education is not effective should be withdrawn from overused drugs and should receive preventive treatment with drugs of proven efficacy. Patients with MOH in whom preventive treatment is not effective should undergo drug withdrawal. Drug intake can be abruptly terminated or restricted in patients overusing simple analgesics, ergots or triptan medication. In patients with long-lasting abuse of opioids, barbiturates or tranquilizers, slow tapering of these drugs is recommended. Withdrawal can be performed on an outpatient basis or in a daycare or inpatient setting.

RESUMEN

BACKGROUND: Headache disorders are both common and burdensome but, given the many people affected, provision of health care to all is challenging. Structured headache services based in primary care are the most efficient, equitable and cost-effective solution but place responsibility for managing most patients on health-care providers with limited training in headache care. The development of practical management aids for primary care is therefore a purpose of the Global Campaign against Headache. This manuscript presents an outcome measure, the Headache Under-Response to Treatment (HURT) questionnaire, describing its purpose, development, psychometric evaluation and assessment for clinical utility. The objective was a simple-to-use instrument that would both assess outcome and provide guidance to improving outcome, having utility across the range of headache disorders, across clinical settings and across countries and cultures. METHODS: After literature review, an expert consensus group drawn from all six world regions formulated HURT through item development and item reduction using item-response theory. Using the American Migraine Prevalence and Prevention Study's general-population respondent panel, two mailed surveys assessed the psychometric properties of HURT, comparing it with other instruments as external validators. Reliability was assessed in patients in two culturally-contrasting clinical settings: headache specialist centres in Europe (n = 159) and primary-care centres in Saudi Arabia (n = 40). Clinical utility was assessed in similar settings (Europe n = 201; Saudi Arabia n = 342). RESULTS: The final instrument, an 8-item self-administered questionnaire, addressed headache frequency, disability, medication use and effect, patients' perceptions of headache "control" and their understanding of their diagnoses. Psychometric evaluation revealed a two-factor model (headache frequency, disability and medication use; and medication efficacy and headache control), with scale properties apparently stable across disorders and correlating well and in the expected directions with external validators. The literature review found few instruments linking assessment to clinical advice or suggested actions: HURT appeared to fill this gap. In European specialist care, it showed utility as an outcome measure across headache disorders. In Saudi Arabian primary care, HURT (translated into Arabic) was reliable and responsive to clinical change. CONCLUSIONS: With demonstrated validity and clinical utility across disorders, cultures and settings, HURT is available for clinical and research purposes.

RESUMEN

Headache disorders are a major public-health priority, and there is pressing need for effective solutions to them. Better health care for headache-and ready access to it-are central to these solutions; therefore, the organisation of headache-related services within the health systems of Europe becomes an important focus. These recommendations are the result of collaboration between the European Headache Federation and Lifting The Burden: the Global Campaign against Headache. The process of development included wide consultation. To meet the very high level of need for headache care both effectively and efficiently, the recommendations formulate a basic three-level model of health-care organisation rationally spread across primary and secondary health-care sectors, taking account of the different skills and expertise in these sectors. They recognise that health services are differently structured in countries throughout Europe, and not always adequately resourced. Therefore, they aim to be adaptable to suit these differences. They are set out in five sections: needs assessment, description of the model, adaptation, standards and educational implications.

RESUMEN

SUNCT syndrome (short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing) is a primary headache characterised by a high frequency of attacks associated with marked autonomic periocular signs and symptoms. Activation of the hypothalamus via the superior salivary nucleus is probably responsible for some of the autonomic involvement observed during SUNCT attacks. We describe a case of SUNCT with unusual autonomic features (e.g., mydriasis) and early onset. Pupillometric studies were performed both in a basal condition (without anisocoria) and after instillation of phenylephrine (a drug with direct sympathomimetic activity) and pilocarpine (a parasympathetic agonist). The findings in this patient seem to indicate involvement of the ocular sympathetic supply in SUNCT, responsible for the mydriasis, and seem to strengthen the possibility that the autonomic phenomena in this syndrome vary with different levels of pain severity.

RESUMEN

The mean age of onset of cluster headache (CH) is in the late third decade. Only few cases of childhood-onset (< 14 years) CH have been reported in the literature. We report the case of an 11-year-old boy who suffered from sudden attacks of shock-like, intense pain, localized in the right orbital region, with associated photophobia, phonophobia, conjunctival injection, lacrimation, nasal congestion, rhinorrhoea and psychomotor agitation. The episodes lasted 60-180 min, and the headache frequency was one to three per day. Physical and neurological examinations, magnetic resonance imaging and blood examinations were normal. The first bout lasted 8 months. Attacks were resistant to every symptomatic and partially to prophylactic treatment that has been tried. The second bout lasted approximately 2 months.

RESUMEN

Typical cases of the most common kinds of headache can be diagnosed and treated by general practitioners (GPs). Non-traumatic patients with de novo acute sudden-onset disabling headaches as well as significant worsening of pre-existing headaches seek care at emergency departments (EDs) and represent a diagnostic challenge for the consultant neurologist, who is the specialist of reference for the entire diagnostic process. Explicit diagnostic criteria for the classification of headache disorders (ICHD-II) are fundamental for verifying the final diagnosis, but in the emergency setting diagnostic and therapeutic guidelines and recommendations, coupled with lists of diagnostic alarms and warnings, may further contribute to the preliminary identification of secondary headaches.

RESUMEN

Corticosteroids appear to be the most rapid-acting of the prophylactic drugs used in the treatment of cluster headache (CH). These agents are frequently employed as a short-term regimen to induce clinical remission. In this study, we assessed in an open fashion the effect of high dose methylprednisolone (MPD) in a group of 13 patients with episodic CH (3 females and 10 males). On the 8th day of the active period, MPD was administered intravenously at the dose of 30 mg/kg body weight, as a 3-h infusion in saline. The attack frequency was followed for 7 days. The mean daily attack frequency before MPD administration was statistically different from that reported after treatment (respectively: 1.38 +/- 0.42 and 0.83 +/- 0.78; P = 0.05 Student's t-test). The mean interval between MPD administration and the occurrence of the first subsequent attack was 3.8 +/- 2.2 days (range: 2-7 days). Only 3 (23%) of 13 patients experienced a complete headache remission. No significant side-effects were noted after MPD administration. These data further demonstrate that in most patients with episodic CH, high-dose systemic steroid administration may invariably interrupt attack recurrence for a few days, but is ineffective in maintaining complete clinical remission. This study also suggests that MPD administered as a solitary dose does not provide any advantage above prednisone in CH treatment.

RESUMEN

Nitric oxide (NO) may participate in the mechanisms underlying vascular headaches, such as migraine and cluster headache (CH), by triggering neurogenic inflammation and activation of fibres conveying nociceptive inputs to the trigeminal ganglion. Similarly to migraine, the administration of the NO donor glyceryltrinitrate (GTN) to CH patients is a known model of inducing spontaneous-like attacks. We carried out a GTN test (0.9 mg, sublingually) in 18 patients with episodic CH in active phase and 12 controls. The plasma levels of NO metabolite nitrites (NO2-), after conversion of nitrates to NO2-, were measured spectrophotometrically at baseline, at the maximum intensity of the induced response (or 45 min after GTN in controls), and 120 min after GTN administration. The basal plasma levels of L-citrulline were also assayed in patients and controls using high-performance liquid chromatography. Basal NO2- levels, similar in GTN-responsive patients and controls (48.3 +/- 10.6 and 44.6 +/- 9.5 micromol/l, respectively) were found to be increased significantly at pain peak in patients (76.1 +/- 10.2 micromol/l) and after 45 min in controls (78.2 +/- 9.6 micromol/l) (P < 0.01 vs. respective baseline values), but not after 120 min, without differences between groups. L-citrulline levels in basal conditions showed no differences between groups (patients 64.8 +/- 11.7, controls 67.3 +/- 10.8 micromol/l). These data do not support the presence of a basal hyperactivity of the L-arginine-NO pathway in CH patients. Increased NO production may be of importance in the mechanisms leading to CH attacks, but other factors are likely to render CH patients hyperresponsive to NO, and ultimately to cause the occurrence of pain and associated features.

RESUMEN

The interval between indomethacin administration and clinical response may be extremely relevant in the assessment of chronic paroxysmal hemicrania (CPH) and other unilateral headache disorders like cluster headache (CH), with which CPH can be confounded. Indomethacin is inactive in CH; however, in some anecdotal reports in recent years, doubt has been cast on the ineffectiveness of indomethacin in CH. In this study, we have re-assessed the effect of indomethacin treatment in a group of 18 patients with episodic CH (three females and 15 males). From the day 8 of the active period, indomethacin 100 mg i.m. was administered every 12 h, for 2 consecutive days, in an open fashion. The mean daily attack frequency before the test (1.6 +/- 0.6) was not statistically different from that on day 1 (2.1 +/- 0.9) and day 2 (1.9 +/- 0.8) after indomethacin administration. The mean interval between indomethacin injection and the following attack (day 1 and day 2) was 4.6 + 1.1 h. We did not observe any refractory period in any patient after indomethacin. Since the 'expected' attack occurred when there theoretically could have been a protective effect after indomethacin administration, it can be reasonably assumed that there is no such protective effect. The use of a test dose of 100 mg i.m. indomethacin (INDOTEST) appears to provide a clear-cut answer in this situation. It may be a useful tool for a proper clinical assessment of unilateral headache with relatively short-lasting attacks when problems of classification arise. A correct diagnosis of CPH or CH is important, since a CPH diagnosis may imply a lifelong treatment with a potentially noxious drug.

RESUMEN

In recent decades whiplash injuries, being a major reason for compensation claims, have become increasingly important in forensic medicine. In view of this, a reliable diagnostic method of assessing cervical range of motion (ROM) is needed. The aim of the present study was to evaluate neck function with a 3D kinematic method compared with clinical evaluation in whiplash injury. Seventy consecutive patients (M/F = 18/52) with a history of whiplash injury (WH) and 46 healthy volunteers (M/F = 24/22), mean age, respectively 33 +/- 9 and 28 +/- 6 years (mean+/-SD) entered the study. Patients suffered from neck pain and/or unilateral headache. A computerized kinematic analysis of the ROM (Elite system) using passive markers and two infrared TV cameras was used. Clinical evaluation of active ROM was also performed both in patients and in 61 controls (M/F = 23/38; mean age 47 +/- 18 years). Thirty out of 70 patients were tested at the time of their first consultation (T0) and 6 months later (T6), and 12 were also followed up after a year (T12). All neck movements, except extension, were significantly reduced in WH subjects compared with controls, in particular lateral bending. Comparing ROM at T0, T6 and T12, no significant differences were found. A global index of motion (GIM), obtained by calculating the sum of ROM in absolute value for all the movements acquired, was significantly reduced in WH compared with control subjects. The interobserver reliability of the clinical evaluation was globally acceptable. On the basis of the clinical evaluation, a significantly reduced ROM was found in all movements in WH subjects compared with an age-matched population. Computing the number of impaired cervical movements (ICMs), a significantly higher number was observed in WH patients than in controls, showing a decreasing trend at T6 and T12, with a significant improvement at T6 vs. T0. The computerized study of neck ROM may constitute a useful tool in the evaluation of WH at baseline and follow-up.

RESUMEN

A variety of headaches are frequently associated with the occurrence of neck pain. The purpose of this paper was to describe the adherence to diagnostic criteria of a series of patients enrolled on the basis of two clinical criteria: (1) unilateral headache without side-shift, and (2) pain starting in the neck and spreading to the fronto-ocular area. One hundred and thirty-two patients (36 male and 96 female) entered the study. Sixty-two patients were assigned to Group A (patients fulfilling criteria 1 and 2), 40 to Group B (criterion 2 only) and 12 to Group C (criterion 1, only). Eighteen subjects were excluded because X-rays of the neck were not available. Patients were evaluated regardless of whether or not they fell into one or more of the following diagnostic categories: cervicogenic headache (CEH), migraine without aura (M) and headache associated with disorders of the neck (HN) (IHS definitions). Fulfillment of the diagnostic criteria for CEH was found to be particularly frequent in Group A. A higher frequency of CEH diagnosis was found when two criteria were used (Group A) than in Group B (P = 0.001); in the former group a higher mean number of diagnostic criteria for CEH were also present (P = 0.001). Group A patients more frequently presented pain episodes of varying duration or fluctuating, continuous pain and moderate, non-excruciating, non-throbbing pain than Group B patients (P = 0.04 and P = 0.08, respectively). In Group C patients, the frequency of these two criteria was relatively low (17%) especially of the first mentioned variable. The presence of at least five of the seven 'pooled' CEH criteria (present in > or = 50% of the patients) might be deemed a reliable cut-off point, allowing the headache to be diagnosed as 'probable' CEH. If patients fulfilling M or HN criteria in addition to the CEH criteria are added to the 'pure' CEH group a total of 74% of Group A patients may have a CEH picture. The temporal pattern of pain and the quality of pain in Group A showed good sensitivity and specificity (> or = 75) when compared with Group B; therefore, the chances of diagnosing a definite CEH are significantly more frequent in patients presenting with unilateral pain that also begins as a neck pain. Head/neck trauma and radiological abnormalities in the cervical spine were not significantly associated with CEH, M or HN diagnoses. An improvement of the current diagnostic IHS criteria might make it possible to avoid the existing, partial overlap of CEH with HN and M. Extensive use should be made of the GON, and other, blockades in the routine work-up of CEH, both in the differential diagnosis and in the mixed forms (CEH + M, and CEH + HN), in order to improve the efficiency of the current diagnostic system.

RESUMEN

Since the first attempt at setting down diagnostic criteria was made in 1990, there has been considerable progress in the field of cervicogenic headache (CEH). CEH makes up a "final common pathway" for several neck disorders that may originate at different levels of the cervical spine. CEH has been defined as being mainly a unilateral headache without sideshift; it may accordingly also be bilateral. Anesthetic blockades are mandatory for scientific work. If the pain is bilateral, it is particularly important that blockades are carried out. Pain stemming from the neck usually spreads to the oculofrontotemporal area. The most characteristic features are symptoms and signs of neck involvement (such as mechanical precipitation of attack, and so forth). Migraine without aura and tension-type headache are the most difficult differential diagnosis problems.

RESUMEN

Proposals for the diagnostic criteria for hemicrania continua (HC) and also for the nosological status of HC are set forth. The clinical constellation of symptoms and signs making up HC consists of: unilaterality without side shift; absolute indomethacin effect; and long-lasting repetitive attacks of varying duration, eventually with a chronic pattern, the pain being mild to severe. For the typical clinical picture of HC, including a positive 'indotest', we propose the term hemicrania continua vera. More or less analogous, but 'indotest-negative' clinical pictures have provisionally been termed hemicrania generis incerti (of undetermined nature). At the present level of knowledge, the diagnosis of hemicrania generis incerti should be made mostly by exclusion. HC may possibly best be classified along with chronic paroxysmal hemicrania (CPH) as this is the only other headache absolutely responsive to indomethacin. The bond between these two headaches on the one hand and cluster headache on the other should, at most, be a loose one. Interrelationships of these four classifiable headaches are briefly discussed.

RESUMEN

More than 16 years after the first description of hemicrania continua (HC), its aetiology and pathogenesis remain obscure. Clinically, HC is considered a syndrome with two pivotal characteristics: (i) strictly unilateral (moderate, fluctuating, relatively long-lasting) headache; and (ii) absolute response to indomethacin. HC is further characterized by some ancillary, but mostly "negative", features such as: (iii) relative paucity of accompaniments; and (iv) lack of precipitating factors. The female preponderance is also remarkable, although not diagnostic in the solitary case. Finally, a non-specific, but remarkable feature is the temporal pattern. HC may present as a remitting or chronic (continuous) headache. In HC, unilaterality and absolute response to indomethacin are considered crucial diagnostically. Existing controversy, such as regarding atypical features, particularly the so-called "HC resistant to indomethacin", is discussed. The nature of hemicrania with negative indomethacin response remains most unclear; it may not belong to the HC cycle at all. Accordingly, we propose that the typical clinical picture of HC, including an absolute response to indomethacin, be termed Hemicrania continua vera. More or less analogous, but indomethacin-resistant, clinical pictures can provisionally be termed Hemicrania generis incerti (of undetermined nature), provided other diagnostic possibilities have been ruled out. The differential diagnosis of HC vs. other unilateral headaches is commented on. Previous attempts at classification of HC into the group chronic daily headache (CDH) are discussed. The only acceptable "link" of HC with the other headaches classified as CDH is the temporal pattern (which is a non-specific feature). HC is probably pathophysiologically different from the others disorders classified under CDH. Conversely, HC and chronic paroxysmal hemicrania share many common features, including the absolute response to indomethacin. HC should probably be included in the IHS group 3.

RESUMEN

The nociceptive flexion reflex (NFR) of the lower limbs (RIII reflex) was examined bilaterally in 54 cluster headache (CH) patients suffering from episodic CH (ECH) and chronic CH (CCH). Fifteen ECH patients were examined in both remission and active phases. The RIII reflex threshold (Tr) and the threshold of pain sensation (Tp) were significantly reduced on the symptomatic side in patients with episodic CH during the bout. During the active phase of episodic CH an inverse correlation was found between the severity of CH (ratio: number of cluster periods/years of illness duration) and the Tp, which may suggest a role for secondary central sensitization in pain pathways. The lower Tr and Tp on the symptomatic side is in keeping with previous observations exploring pain mechanisms using different methods (i.e. corneal reflex, pain pressure threshold). On the whole, these data tie in with the view of an impairment of the pain control system, which parallels the periodicity of the disorder in the episodic form.

RESUMEN

The administration of nitroderivatives in cluster headache (CH) sufferers is the most reproducible experimental paradigm to induce spontaneous-like pain attacks. Previous uncontrolled studies have reported that the local use of anaesthetic agents in the area of the sphenopalatine fossa is able to extinguish nitroglycerin (NTG)-induced pain in CH. The present study, carried out according to a double-blind placebo-controlled design, included 15 CH patients, six with episodic CH (mean +/- SD age of 36.8+/-5.6 years), and nine with chronic CH (37.8+/-10.4 years). Patients had undergone a standard NTG test (0.9 mg sublingually), during which the intensity of pain was scored using a visuoanalogic scale (VAS, range 0-10). Nine patients (two with the episodic form, seven with the chronic form) experienced a typical, spontaneous-like attack on the usual side, occurring in all cases within 45 min. In these patients, the test was repeated with an interval of 2 days, and once pain intensity reached 5 on the VAS, a 10% solution of cocaine hydrochloride (1 ml, mean amount per application 40-50 mg), or 10% lidocaine (1 ml), or saline was applied using a cotton swab in the area corresponding to the sphenopalatine fossa, under anterior rhinoscopy. This was done in both the symptomatic and the non-symptomatic side, for 5 min. Treatments were always performed randomly, in separate sessions. All patients responded promptly to both anaesthetic agents, with complete cessation of induced pain occurring after 31.3+/-13.1 min for cocaine and 37.0+/-7.8 min for lidocaine (M+/-SD). In the case of saline application, pain severity increased thereafter, and extinction of the provoked attacks occurred with a latency of 59.3+/-12.3 min (P<0.01 and P<0.01 vs. cocaine and lidocaine, respectively, Mann-Whitney U-test). While further suggesting that the sphenopalatine ganglion participates in the mechanisms of pain, these findings indicate that the local administration of the anaesthetic agents cocaine and lidocaine is effective on NTG-induced CH attacks, and may be used in the symptomatic treatment of this disorder.

RESUMEN

The concept of headache originating/starting in the neck is revised and considered in the light of previous descriptions of syndromes and entities and with reference to the current diagnostic systems for the classification of headache and other head pain. Cervicogenic headache (CEH), a clinical picture recently described by Sjaastad and coworkers and listed in the International Association for the Study of Pain (IASP) Classification, is analyzed, also taking into consideration its diagnostic criteria in terms of sensitivity and specificity. The problem of a differential diagnosis with migraine, tension headache and other well defined forms of unilateral headaches is discussed with reference to a case series of 114 patients who were selected based on their adherence to two fundamental criteria: (i) side-locked unilaterality of pain; and (ii) pain starting in the neck and spreading to the fronto-orbital area. Based on the results, these simple criteria can contribute to a preliminary identification of possible CEH cases that may then undergo a sequence of clinical and instrumental procedures in order to confirm the diagnosis and, possibly, to localize the level(s) of dysfunction in the cervical spine which may be the target for therapeutic investigations, whether invasive or non-invasive.

RESUMEN

The term "whiplash" commonly refers to symptoms and signs associated with a mechanical event such as a sudden acceleration and deceleration of the neck (due, in the majority of cases, to a road accident), instead of to the mechanism itself. The recent Quebec Classification of Whiplash Associated Disorders (WAD) contributed to define nosographically all the clinical manifestations usually grouped under the terms acute/post-traumatic and late "syndrome". In the late phase of WAD, neck pain and neck muscle contraction have been reported in all cases, together with headache in over 50%. "Headache stemming from the neck", despite numerous attempts to classify this entity (i.e. cervicogenic headache) according to the IASP classification (headache associated with neck disorders), is still a subject of debate. An adequate multiparametric procedure is required to study WAD, which takes into account: the patient's principal details; an exact reconstruction of the event; description and analysis of the signs and symptoms, with various complications and correlated dysfunctions; an objective neurological and neck-shoulder examination; and a battery of complementary instrumental tests which are described in this study. These investigations include evaluation of muscle tension (manual palpation, algometry, EMG recording), kinematic analysis of the cervical spine, neuropsychological and psychological evaluation, and evaluation of disability. In order to assess cervical spine mobility in WAD patients, a 3D kinematic analysis by means of the ELITE system and clinical evaluation were performed in our setting. Seventy patients with whiplash injury and 46 healthy volunteers were enrolled in the study. Patients were tested at the time of first consultation and again 6 months and 12 months later. Clinical evaluation of the range of motion was performed both in patients and in 41 healthy volunteers. Furthermore, patients diagnosed according to the WAD Classification as grade 2 (n = 68) or grade 3 (16) underwent a Quality of life (QoL) evaluation, measured using the short form (36-item) Health Survey (SF36) and the migraine-specific questionnaire (MSQ). According to our data, whiplash patients showed an impairment of cervical spine mobility, as well as a poor QoL, compared to a control group population, even though we observed a trend towards improvement over time in cervical ROM.
