Efficacy of a long-term acting triptan for Headache attributed to aeroplane travel: a case report.

Headache attributed to aeroplane travel (AH) is a well-defined nosological entity whose diagnostic criteria have been published in the third provisional International Classification of Headache Disorders (ICHD) and confirmed in the definitive version. Despite the severe intensity of pain, less than half of the AH cases described used medications for preventing the attack. The most frequent prophylactic therapy spontaneously used by sufferers are simple analgesics, non-steroidal anti-inflammatory drugs (NSAIDs), and nasal decongestants, achieving a complete or partial benefit in about 50% of patients. A complete response of AH to fast-acting triptans has been reported. We describe the case of a 37-year-old migrainous woman suffers from AH in about 75% of her flights who preempted the attacks by using a long-acting triptan (frovatriptan). Giving triptans' mechanism of action, an involvement of the trigemino-vascular system in the pathogenesis of AH could be advanced.

Jean-Martin Charcot (1825-1893) and the "Alice in Wonderland syndrome".

The "Alice in Wonderland syndrome" (AIWS) is a neurological disorder characterized by altered body schema perception, visual, or somesthetic symptoms, which is frequently associated with migraine. In this article, we present the earliest known description of symptoms attributable to AIWS in the medical literature. During a lecture held on November 22, 1887, at the Salpêtrière, Jean-Martin Charcot (1825-1893) examined a patient with somesthetic symptoms (partial macrosomatognosia) in the context of migraine with aura. Although this condition was not known at the time, Charcot tried to provide an accurate semiological and nosographic framework of this case, attributing the complex of symptoms to migraine with aura and epilepsy with sensory symptoms. With intellectual honesty and clinical prudence, Charcot correctly pointed to a disturbance in the excitability of cortical areas responsible for processing and perceiving sensory stimuli.

Update on headache and brain tumors.

Headache is one of the leading symptoms often associated with brain tumours. Secondary headaches attributed to intracranial neoplasias have been included in subchapter 7.4 of the third edition of the International Classification of Headache Disorders (ICHD-3). According to ICHD-3, the headache may be attributed to a brain tumour if it has developed in close temporal relation with the development of the neoplasia, has significantly worsened in parallel with the worsening of the tumour, and/or has significantly improved following the successful treatment of the neoplasia. Brain tumour headache was traditionally thought to display some specific clinical characteristics, including worsening in the morning and/or when lying down, being aggravated by Valsalva-like manoeuvres and accompanied by nausea and/or vomiting; however, the studies performed after the advent of modern neurodiagnostic techniques have pointed out that the "classic" brain tumour headache is uncommon, particularly at the time of clinical presentation. Therefore, it becomes critical to seek some specific factors associated with the presence of an intracranial mass (the so-called "red flags") that can guide the physician to establish an accurate diagnosis.

A prospective study on osmophobia in migraine versus tension-type headache in a large series of attacks.

BACKGROUND: In literature, osmophobia is reported as a specific migrainous symptom with a prevalence of up to 95%. Despite the International Classification of Headache Disorders 2nd edition proposal of including osmophobia among accompanying symptoms, it was no longer mentioned in the ICHD 3rd edition. METHODS: We conducted a prospective study on 193 patients suffering from migraine without aura, migraine with aura, episodic tension-type headache or a combination of these. After a retrospective interview, each patient was asked to describe in detail osmophobia, when present, in the following four headache attacks. RESULTS: In all, 45.7% of migraine without aura attacks were associated with osmophobia, 67.2% of migraineurs reported osmophobia in at least a quarter of the attacks. No episodic tension-type headache attack was associated with osmophobia. It was associated with photophobia or phonophobia in 4.3% of migraine without aura attacks, and it was the only accompanying symptom in 4.7% of migraine without aura attacks. The inclusion of osmophobia in the ICHD-3 diagnostic criteria would enable a 9.0% increased diagnostic sensitivity. CONCLUSION: Osmophobia is a specific clinical marker of migraine, easy to ascertain and able to disentangle the sometimes challenging differential diagnosis between migraine without aura and episodic tension-type headache. We recommend its inclusion among the diagnostic criteria for migraine as it increases sensitivity, showing absolute specificity.

Prevalence of headache attributed to aeroplane travel in headache outpatient populations: An Italian multicentric survey.

BACKGROUND: To assess the prevalence of headache attributed to aeroplane travel (AH) in patients referred to Italian Headache Centres. MATERIAL AND METHOD: 869 consecutive patients visiting six Italian headache centres during a 6 month-period (October 2013 to March 2014) were enrolled in the survey. Among them, 136 (15.6%) had never flown and therefore were excluded from the study. The remaining 733 patients (f = 586, m = 147; age 39.1 ± 17.3) were asked about the occurrence of headache attacks during flight; those who answered the question positively filled in a detailed questionnaire that allowed the features of the attacks to be defined. RESULTS: Headache attacks during the flight was reported by 34/733 subjects; four presented attacks fulfilling ICHD-3 beta (1) criteria for migraine without aura and therefore were not further considered. The features of the remaining 30 (4.0%; m = 18, f = 12, age 36.4 ± 7.3) completely fulfilled the ICHD-3 beta criteria for AH. In more detail, the pain was unilateral (fronto-orbital: n = 23; fronto-parietal: n = 7; without side-shift: n = 25, with side-shift: n = 5), lasting up to 30 min in 29 subjects. All the patients reported the pain as very severe or unbearable and landing as the phase of travel in which the attack appeared. In four cases, a postictal, milder, dull headache could last up to 24 hours. Accompanying symptoms were present in eight cases (restlessness: n = 5; conjunctival injection and tearing: n = 2; restlessness + ipsilateral conjunctival injection and tearing: n = 1). The fear of experiencing further attacks negatively affected the propensity for future flights in 90.0% of subjects (n = 27). In all the patients, AH onset did not coincide with the first flight experience. Concomitant migraine without aura was diagnosed in 24, tension-type headache in four, migraine without aura + tension-type headache in two cases; none suffered from cluster headache. Five subjects reported AH on each flight, 20 in > 50% of flights, five occasionally. Despite the severe intensity of the pain, only one third of this sample spontaneously reverted to a pharmacological treatment; the most useful strategy combines a decongestant nasal spray plus the intake of a simple analgesic 30 min before the estimated attack. Spontaneous manoeuvres were applied by 18 patients (Valsalva-like: n = 12; compression: n = 2; both manoeuvres: n = 4), more often without significant improvement. These data confirm our previous finding on the clinical features of AH. CONCLUSION: AH was found in 4.0% of a multicentre, large sample of patients with flight experiences. Although limited to a sample of patients followed in six Italian headache centres, to the best of our knowledge these are the first epidemiological data on AH gathered by direct interview. If properly investigated, AH seems to be a not infrequent condition, which, when diagnosed, could probably be prevented in many cases.

Headache Attributed to Aeroplane Travel: An Historical Outline.

INTRODUCTION: Headache attributed to aeroplane travel (AH) is one of the new nosological entries in the International Classification of Headache Disorders (ICHD) 3 beta. MATERIALS AND METHODS: This study retraces the history of headache related to flight, from the initial description to the modern reports, on the basis of original sources. RESULTS: Head pain related to flight has been reported since the beginning of flight era. However, most of those early cases are easily recognized as secondary to an exceptional barotrauma and/or a sinusitis concomitant with the flight. Instead, contemporary research identified a new nosological entity, AH, which by definition occurs in normal flying conditions and in absence of any sinus pathology. Moreover, we identified recently similar forms of headache, triggered by sudden changes of external pressure (rapid descent from mountain, mountain descent headache, MDH); and ascent from diving, diving ascent headache (DAH). CONCLUSION: Head pain related to flight has been reported since the origin of aviation, but it was caused by an exceptional barotrauma or a respiratory infection. Instead, AH occurs in normal flying conditions. Two newly identified conditions, MDH and DAH, appear to share a common pathogenetic mechanism with AH: namely the imbalance between intrasinusal and external air pressure. Therefore, we assert that an expansion of this entity of AH is something that should be considered in the next ICHD.

Sports, physical activity and headache in the classical age: historical descriptions from the first sports textbook, "De arte gymnastica", by Girolamo Mercuriale.

BACKGROUND AND OBJECTIVES: The relationship between physical activity, sports and headache presents a growing interest, testified by numerous papers recently published. The correlation between headache and sporting activities or physical exercise dates back to the classical age. We aim at promoting the development of more studies focused on the relationship between headache and physical activity. METHODS: We analysed the book "De arte gymnastica", written by Girolamo Mercuriale (Forlì, Italy, 1530-1606), and considered the first "sports medical textbook". We discuss these classical literature findings in the light of the International Classification of Headache Disorders, 3rd edition. RESULTS: The Author's work derives from the systematic revision of Greek, Roman and Arabic literatures about the matter. Despite some references to inveterate headaches or cold-related pains, Mercuriale does not gather specific clinical characterisations of different types of headache. However, interestingly, he reports detailed descriptions of how the same sport, or the same physical activity, could cause or give relief from head pain, depending on the precise way of practising. Mercuriale summarises 18 sports or physical activities that can give relief from headache; conversely, running or heavy activities, such as boxing, appear among the 12 contraindicated sports for people suffering from headache. CONCLUSIONS: "De arte gymnastica", by Girolamo Mercuriale, is the first textbook on sports medicine. Headache if often cited along the treatise: different sports and physical activities, or various ways of practising the same action could produce opposite effects for people suffering from headache.

Aeroplane headache, mountain descent headache, diving ascent headache.. Three subtypes of headache attributed to imbalance between intrasinusal and external air pressure?

Background Headache attributed to aeroplane travel (AH) is currently codified in Chapter 10.1.2 of the International Classification of Headache Disorders 3 beta (ICHD 3 beta). After our previous papers, the investigation was enlarged to 200 patients. Material and methods People affected by AH contacted us by mail and agreed to fill in a detailed anonymous questionnaire that allowed a thorough definition of the headache features. Results This extended case series allows us to confirm most of the clinical features of AH, reported in our previously published article, and to partially modify others. New results mainly regard the higher occurrence of accompanying symptoms and the presence of a long lasting mild headache phase, usually not exceeding 24 h, that follows the short lasting acute pain, the duration of which has been confirmed as less than 30 min. Moreover, headache attacks identical to those of AH are reported in a portion of patients, triggered by the ascent during free/snorkeling or scuba diving and rapid descent from high mountains. Conclusion The coexistence of AH with headache triggered by different environmental factors (ascent during free/scuba diving and descent from high mountains) indicates a common causal mechanism, that is, the imbalance between intrasinusal and external air pressure. We propose to classify them together, within Chapter 10 " Headache attributed to disorders of homoeostasis", under a unique heading " Headache attributed to imbalance between intrasinusal and external air pressure".

A lost track in ICHD 3 beta: A comprehensive review on osmophobia.

Background Osmophobia (Os) has been reported to be much more prevalent in migraine (M) than in other primary headaches, and its high specificity in the differential diagnosis between M and tension-type headache (TTH) has been reported. Os was included in the ICHD II Appendix as a diagnostic criterion of M. It disappeared in ICHD-3 beta. To understand this choice, we reviewed the literature after 2004. Methods This was a systematic review. We searched in PubMed, MEDLINE and Cochrane library for "osmophobia", "odour/odorphobia AND headache", "odour/odor hypersensitivity AND headache" and "olfactory hypersensitivity AND headache". Results 112 papers cited Os as an accompanying symptom of headache; 16 focused on Os in M diagnosis. With the data from 40 articles, we calculated the pooled prevalence of Os in 14,360 patients (2281 pediatric) affected by M (n = 12,496) and TTH (n = 1864). In M, the prevalence was 48.5% (CI 95% 41.4 to 55.8%) in adults and 23.4% (CI 95% 15.7 to 33.4%) in pediatric patients; in TTH, the prevalence was 8.9% (CI 95% 4.6 to 13.5%) in adults and 7.9% (CI 95% 3.3 to 18.1%) in pediatric patients. Ten of these papers allowed us to calculate the sensibility and specificity of Os in differential diagnosis between M and TTH. In adults, the value of specificity was 94.1% (CI 95% 88.9 to 96.9%), and sensitivity was 51.4% (CI 95% 38.4 to 64.2%). In pediatric patients, specificity was 92.0% (CI 95% 81.9 to 96.7%), and sensitivity was 22.1% (CI 95% 10.1 to 41.8%). Conclusion The literature endorses the inclusion of Os among M diagnostic criteria. On this ground, the decision to remove Os from ICHD 3 beta appears unjustified and a revision of this choice is recommended.

Acute-on-chronic subdural hematoma: the death of the famous XIX century soprano Maria Malibran-a study of the sources.

Maria Malibran (1808-1836) is one of the most famous sopranos of the nineteenth century. In 1825, along with her father, the renowned tenor Manuel Garcia, she introduced the Italian opera in America for the first time. The European debut in Paris (1828) definitively crowned her as a star. Thus, she was requested by the most famous European theaters. In July 1836, during an equestrian excursion in London, she fell from her horse dashing her head against the ground, resulting in a state of insensibility. Since that accident, she had suffered from continual headache and nervous attacks, but she continued to work. In September 1836, she attended a music festival in Manchester, but her health rapidly worsened: episodes of nervous attacks, headache, and fainting occurred with higher frequency. At the end of a representation, she was attacked by violent convulsions. In the following days, she was laid in a kind of stupor. Afterward, she died at the age of 28. The hypothesis that prolonged efforts during her performance could have provoked a rebleeding of a pre-existent chronic subdural hematoma should be taken into account as a possible cause of death.

Scent of aura? Clinical features of olfactory hallucinations during a migraine attack (OHM).

Introduction Olfactory hallucination during a migraine attack (OHM) is a rare phenomenon. At present, it is not considered a manifestation of migraine aura. Material and methods The clinical features of OHM were collected in 11 patients. Results Of the 11 patients, 10 had migraine without aura and one migraine with aura associated with OHM. Mean age at onset of headache and at appearance of OHM were respectively 17.8 and 32.3 years. Migraine average frequency was 3.9 attacks/month, 19% of them being associated with OHM. The temporal pattern of OHM maintained the same characteristics in the different attacks. OHM onset was described as sudden ( n = 5), gradual ( n = 3), initially sudden and then gradual ( n = 2), or developing in a few seconds ( n = 1). In most of the cases ( n = 8) OHM lasted from 3 to 10 minutes; it persisted during the pain phase (2-24 hours) in only three patients. The type of the perceived smell was invariably constant in nine patients. Conclusion OHM features fulfilled the ICHD-III beta criteria for typical aura.

Cluster headache: When to worry? Two case reports.

Background The clinical criteria for cluster headache (CH) are included in Chapter 3 of the International Classification of Headache Disorders, 3rd beta edition (ICHD-III). CH may sometimes be secondary to other pathologies. Case reports We report two patients in whom the clinical features of CH initially fulfilled the ICHD-III criteria, but who later presented some radical modifications in headache natural history as a result of a secondary pathology. The first case of CH was secondary to a pontine cavernous angioma and the second to a cerebral venous thrombosis. Conclusion We highlight the importance of clinical modifications of CH that could suggest clinical investigations should be performed or repeated to exclude a secondary pathology in a previously diagnosed cluster headache. Some of the pathological mechanisms of CH and brain lesions are discussed.

Hemicrania Continua-Like Headache Related to Transdermal Nitroglycerine Therapy.

Several cases of symptomatic hemicrania continua (HC) have been reported. A 66-year-old man, suffering from migraine without aura, presented with a four month history of a new headache fulfilling the ICHD 3beta clinical criteria for HC. HC onset was strictly related to the use of transdermal nitroglycerine patch (TNP). In agreement with the cardiologist, TNP was discontinued and the headache promptly disappeared; symptoms reappeared within 6-12 hours after nitroglycerine reintroduction. After permanent discontinuation of TNP, headache disappeared at one year follow-up. To the best of our knowledge, this is the first report of the occurrence of an HC-like headache related to TNP.

The Case of the Woman Who Did Never Dare to Fly: Headache Attributed to Imbalance Between Intrasinusal and External Air Pressure.

BACKGROUND: A new form of headache, Headache attributed to aeroplane travel (AH), has been recognized within the International Classification of Headache Disorders 3 beta (ICHD-3beta). In 8 out of 85 AH cases we identified the coexistence of a headache with identical features of AH, but appearing during the rapid descent by car from a high mountain. Pain began shortly after the rapid descent from a medium altitude of 1920 m above sea level, the maximum peak of intensity developing within a few minutes. All of the patients reported the disappearance of pain within 20 minutes of the rapid descent. CASE: We recently observed a 36-year-old woman who experienced recurrent headache attacks that were constantly triggered by rapid descent from high altitude by car. Negatively shaped by this experience, the patient never dared to fly. CONCLUSION: Headache attacks sharing the same features and occurring in three distinct conditions of pressure variations (aeroplane travel, rapid altitude mountain descent, snorkelling, or scuba diving) have already been reported, although the last two only anecdotally. If confirmed by further case series, they could be gathered together in a unique heading: Headache attributed to imbalance between intrasinusal and external air pressure within the 10th chapter: Headache attributed to disorders of the homoeostasis.

Angiotensin II receptor blockers: a new possible treatment for chronic migraine?

The objective is to suggest a possible role of different angiotensin receptor blockers in the treatment of chronic migraine, especially in hypertensive subjects. Chronic migraine is a highly disabling disorder affecting between 1.4 and 2.2 % of the general population. Despite many pharmacological and non-pharmacological treatments proposed, the results are rather discouraging. Therefore, we believe that should be highlighted all the possible therapies that may lead to an improvement of the symptomatology. Particularly, data available on efficacy of ARBs in preventing chronic migraine are poor. Methods include case reports, literature review and discussion. We report three cases recently treated with angiotensin II receptor blockers that showed a significant improvement, never previously presented with more conventional treatments, including beta blockers. In all three cases, we obtained the reversibility from a chronic migraine to an episodic. Taking a cue from this observation, we consider desirable large controlled, randomized trials to assess the effectiveness of ARBs both in CM hypertensive patients and in patients who do not require anti-hypertensive therapy; furthermore are desirable comparative studies between the various ARB inhibitors to assay any intermolecular differences in efficacy.

Efficacy of frovatriptan as compared to other triptans in migraine with aura.

BACKGROUND: The treatment of migraine attacks with aura by triptans is difficult since triptans most probably are not efficacious when taken during the aura phase. Moreover, there are insufficient data from randomised studies whether triptans are efficacious in migraine attacks with aura when taken during the headache phase. In this metaanalysis, we aimed to compare the efficacy of frovatriptan versus rizatriptan, zolmitriptan, and almotriptan. METHODS: Five double-blind, randomized, controlled crossover trials were pooled. All trials had an identical design. Patients were asked to treat three consecutive migraine attacks with frovatriptan 2.5 mg and three consecutive migraine attacks with a comparative triptan (rizatriptan 10 mg; zomitriptan 2.5 mg; almotriptan 12.5 mg). RESULTS: In this analysis, 117 migraine attacks with aura could be included (intention-to-treat population). The mean headache intensity after 2 hours was 1.2 +/- 1.0 for frovatriptan and 1.6 +/- 1.0 for the other triptans (p<0.05); all triptans showed significant improvement of headache. Frovatriptan resulted in significantly lower relapse rates at 24 hours and 48 hours when taken in migraine attacks with aura. CONCLUSIONS: Our data suggest that frovatriptan is efficacious and even superior in some endpoints also when taken during the headache phase in migraine attacks with aura. This is of particular importance for those many patients who have migraine attacks both without and with aura.

Diagnosis and management of headache attributed to airplane travel.

The headache attributed to airplane travel, also named "airplane headache", is characterized by the sudden onset of a severe head pain exclusively in relation to airplane flights, mainly during the landing phase. Secondary causes, such as upper respiratory tract infections or acute sinusitis, must be ruled out. Although its cause is not thoroughly understood, sinus barotrauma should be reasonably involved in the pathophysiological mechanisms. Furthermore, in the current International Classification of Headache Disorders, rapid descent from high altitude is not considered as a possible cause of headache, although the onset of such pain in airplane travellers or aviators has been well known since the beginning of the aviation era. On the basis of a survey we conducted with the courteous cooperation of people who had experienced this type of headache, we proposed diagnostic criteria to be added to the forthcoming revision of the International Classification of Headache Disorders. Their formal validation would favour further studies aimed at improving knowledge of the pathophysiological mechanisms involved and at implementing preventative measures.
