To evaluate therapies employed in patients presenting to the emergency department (ED) with a chief complaint of non-traumatic headache to check if guidelines are followed. A 6-month retrospective analysis of the ED records of all the patients who referred to the ED of the University Hospital of Trieste for non-traumatic headache was performed. Out of 37.335 admissions, 336 patients were selected (0.9%). Diagnosis at discharge was primary headache (25.6%), secondary headache (40.5%), and headache \"not otherwise specified\" (33.9%). One-hundred-ninety-three patients were treated in mono- (51.8%) or poly-therapy (48.2%), with NSAIDs (46.5%), benzodiazepines (13.4%), antiemetics (10.7%), analgesics (8.3%), opioids (1.6%), triptans (1.5%), and other drugs (17.7%). NSAIDs, particularly ketorolac, are the class of drugs most often prescribed in ED, independently of the discharge diagnosis. Metoclopramide is rarely used in monotherapy (4%), but it is the drug most frequently used in association with NSAIDs (19.3%). Only two migraineurs received triptans. Mean time spent in ED was 231 ± 130 min, which was significantly longer in patients who received treatment (272 ± 141 vs. 177 ± 122 min; p = 0.003). No drugs had any side effects. In accordance with the current guidelines, NSAIDs monotherapy or in association with antiemetics were the drugs most often prescribed in ED. Opioids were rarely used probably because of potential sedative side effects. Only very few patients received triptans. Special attention should be drawn also in ED to apply the International Classification of Headache Disorders criteria, which can lead to clarify the diagnosis and receive the specific treatment.

The diagnosis of primary headache disorders is clinical and based on the diagnostic criteria of the International Headache Society (ICHD-3-beta). However several brain conditions may mimic primary headache disorders and laboratory investigation may be needed. This necessity occurs when the treating physician doubts for the primary origin of headache. Features that represent a warning for a possible underlying disorder causing the headache are new onset headache, change in previously stable headache pattern, headache that abruptly reaches the peak level, headache that changes with posture, headache awakening the patient, or precipitated by physical activity or Valsalva manoeuvre, first onset of headache ≥50 years of age, neurological symptoms or signs, trauma, fever, seizures, history of malignancy, history of HIV or active infections, and prior history of stroke or intracranial bleeding. All national headache societies and the European Headache Alliance invited to review and comment the consensus before the final draft. The consensus recommends brain MRI for the case of migraine with aura that persists on one side or in brainstem aura. Persistent aura without infarction and migrainous infarction require brain MRI, MRA and MRV. Brain MRI with detailed study of the pituitary area and cavernous sinus, is recommended for all TACs. For primary cough headache, exercise headache, headache associated with sexual activity, thunderclap headache and hypnic headache apart from brain MRI additional tests may be required. Because there is little and no good evidence the committee constructed a consensus based on the opinion of experts, and should be treated as imperfect.

OBJECTIVE: To increase the use of evidence-informed approaches to diagnosis, investigation, and treatment of headache for patients in primary care.
METHODS: A comprehensive search was conducted for relevant guidelines and systematic reviews published between January 2000 and May 2011. The guidelines were critically appraised using the AGREE (Appraisal of Guidelines for Research and Evaluation) tool, and the 6 highest-quality guidelines were used as seed guidelines for the guideline adaptation process.
RESULTS: A multidisciplinary guideline development group of primary care providers and other specialists crafted 91 specific recommendations using a consensus process. The recommendations cover diagnosis, investigation, and management of migraine, tension-type, medication-overuse, and cluster headache.
CONCLUSIONS: A clinical practice guideline for the Canadian health care context was created using a guideline adaptation process to assist multidisciplinary primary care practitioners in providing evidence-informed care for patients with headache.

BACKGROUND: China may have the largest population of headache sufferers and therefore the most serious burden of disease worldwide. However, the rate of diagnosis for headache disorders is extremely low, possibly due to the relative complexity of headache subtypes and diagnostic criteria. The use of computerized clinical decision support systems (CDSS) seems to be a better choice to solve this problem.
METHODS: We developed a headache CDSS based on ICHD-3 beta and validated it in a prospective study that included 543 headache patients from the International Headache Center at the Chinese PLA General hospital, Beijing, China.
RESULTS: We found that the CDSS correctly recognized 159/160 (99.4%) of migraine without aura, 36/36 (100%) of migraine with aura, 20/21 (95.2%) of chronic migraine, and 37/59 (62.7%) of probable migraine. This system also correctly identified 157/180 (87.2%) of patients with tension-type headache (TTH), of which infrequent episodic TTH was diagnosed in 12/13 (92.3%), frequent episodic TTH was diagnosed in 99/101 (98.0%), chronic TTH in 18/20 (90.0%), and probable TTH in 28/46 (60.9%). The correct diagnostic rates of cluster headache and new daily persistent headache (NDPH) were 90.0% and 100%, respectively. In addition, the system recognized 32/32 (100%) of patients with medication overuse headache.
CONCLUSIONS: With high diagnostic accuracy for most of the primary and some types of secondary headaches, this system can be expected to help general practitioners at primary hospitals improve diagnostic accuracy and thereby reduce the burden of headache in China.

The first edition of the Italian diagnostic and therapeutic guidelines for primary headaches in adults was published in J Headache Pain 2(Suppl. 1):105-190 (2001). Ten years later, the guideline committee of the Italian Society for the Study of Headaches (SISC) decided it was time to update therapeutic guidelines. A literature search was carried out on Medline database, and all articles on primary headache treatments in English, German, French and Italian published from February 2001 to December 2011 were taken into account. Only randomized controlled trials (RCT) and meta-analyses were analysed for each drug. If RCT were lacking, open studies and case series were also examined. According to the previous edition, four levels of recommendation were defined on the basis of levels of evidence, scientific strength of evidence and clinical effectiveness. Recommendations for symptomatic and prophylactic treatment of migraine and cluster headache were therefore revised with respect to previous 2001 guidelines and a section was dedicated to non-pharmacological treatment. This article reports a summary of the revised version published in extenso in an Italian version.

Primary headaches, whose aetiologies cannot be identified by current diagnostic methods, represent the most frequent headaches and must be distinguished from secondary or symptomatic headaches, e.g. related to traumatic, vascular, inflammatory or neoplastic processes. Only an appropriate treatment will meet the expectations of patients, for who even a mild headache may generate important fears and handicaps. Medical history and physical examination form the basis for targeting the right diagnosis before any biological or radiological testing. The article presents guidelines implemented at the Geneva University Hospitals by the Pain Network of the institution. Therapeutic modalities and recommendations concerning the need for specialized assessments are presented to provide a framework in both emergency situation and long-term care.

Some patients suffering from headache require neurologic examination. The objective of the guidelines for the treatment of headaches is to help physicians in their daily care for headache patients. In most patients, the diagnosis of migraine has not been made by a physician and they have not received appropriate care to treat migraine attacks. New therapeutic methods (for acute and preventive treatment) have been introduced in the past fifteen years. Triptans should be offered to patients that fail to respond to usual analgesics, those with moderate to severe migraine in particular. Depending on comorbidity, preventive therapy should be recommended to individuals with frequent or prolonged migraine attacks. In patients with tension headaches, organic causes underlying the headache should be ruled out, while the treatment includes pharmacological and non-pharmacological measures. Although rare, patients with cluster headaches suffer severe pain; oxygen inhalation or triptans are recommended for acute attack, and preventive therapy may be indicated in some cases. The guidelines provide classification, diagnostic criteria and therapeutic principles for primary headaches. All recommendations listed in the guidelines are based on meta-analyses and recommendations from the world literature, with special reference to therapeutic options available in Croatia.

In comparison with the previous version, the Dutch College of General Practitioners\' practice guideline \'Headache\' has been improved in several respects. The addition of information on cluster headache, tension headache and substance-induced headache may benefit the daily practice of the general practitioner. The list of alarm symptoms is useful for distinguishing between secondary and primary types of headache. With respect to substance-induced headache, there is a difference from the international criteria: according to the latter, the diagnosis may also be made if the headache does not completely disappear but reverts back to the previous pattern. There is a need for studies into the non-medicinal treatment of tension headache. In these practice guidelines, the medicinal treatment of migraine is largely consistent with the guidelines of The Netherlands Society of Neurology.
