Revised 2004 International Classification of Headache Disorders: New Headache Types

In 1988, the International Headache Society created a classification system that has become the standard for headache diagnosis and research. The International Classification of Headache Disorders galvanized the headache community and stimulated nosologic, epidemiologic, pathophysiologic, and genetic research. It also facilitated multinational clinical drug trials that have led to the basis of current treatment guidelines. While there have been criticisms, the classification received widespread support by headache societies around the globe. Fifteen years later, the International Headache Society released the revised and expanded International Classification of Headache Disorders second edition. The unprecedented and rapid advances in the field of headache led to the inclusion of many new primary and secondary headache disorders in the revised classification. Using illustrative cases, this review highlights 10 important new headache types that have been added to the second edition. It is important for neurologists to familiarize themselves with the diagnostic criteria for the frequently encountered primary headache disorders and to be able to access the classification (www.i-h-s.org) for the less commonly encountered or diagnostically challenging presentations of headache and facial pain.

Pain management in the ED

Recent regulatory and legal scrutiny has raised concerns about the over- and undertreatment of pain in the hospital. This debate stems from either the overly aggressive approach to the management of pain with opioids or, alternatively, to the barriers preventing the appropriate prescribing of these medications. The media attention on diversion of controlled substances for illicit purposes has intensified this debate, highlighting the possible overuse of these medications in the treatment of nonmalignant pain. Because pain is a highly common presenting complaint in the ED, EPs are pivotal players in these controversies. Accordingly, they must apprise themselves of pain management skills and continue to help those in need of appropriate medications while thwarting inappropriate prescribing. This review offers a synopsis of the pitfalls associated with ED pain management and provides recommendations for selected conditions.

Clinical warning criteria in evaluation by computed tomography the secondary neurological headaches in adults

Our aims were to investigate the frequency of intracranial lesions detected by cranial computed tomography (CT-scan) amongst adult patients who had clinical warning criteria (CWC) for secondary neurological headaches and to determine the importance of CWC in predicting a possible lesion on CT-scan. Seventy consecutive patients with headache exhibiting CWC were included in this prospective study. The CWC included: (i) increase in the intensity and frequency of headache; (ii) abrupt onset of headache; (iii) persistence of headache despite analgesics; (iv) alteration of the characteristics of headache; and (v) presence of focal neurological symptoms or findings. The mean age of the patients was 46.5 years; the female-to-male ratio was 1.5. Of the patients, 35.7% had a neurological cause identified by CT-scan, and 64.3% had normal CT-scan. In the patients without lesion, of headaches, 64.4% were primary, and 35.6% were from undefined headache group. Although, of the above criteria, only the 5th was different markedly in the patients with lesion than the patients without lesion, in evaluation by CT-scan the secondary neurological headaches in adults, all CWC should look for absolutely in their history and physical examination.
