ReviewPsychiatric comorbidity in childhood and adolescence headache.
Primary headaches among children and adolescents have a substantial impact on quality of life, daily activities, social interaction, and school performance in combination with psychopathological symptoms. The main purpose of the present paper is to summarize clinical and epidemiological evidence for psychiatric comorbidity among children and adolescents with headaches, to describe how evidence in headache research suggest different pathways involved in the development and maintenance of these comorbid conditions, and finally suggest some elements professionals may find helpful to assess the scope of complaints, related functional impairment, and potential precipitating factors in planning of more targeted treatments.

ReviewWhen indomethacin fails: additional treatment options for "indomethacin responsive headaches".
Indomethacin has been used for the treatment of headache disorders since the 1960's, shortly after it was introduced as a treatment for pain and joint swelling in rheumatologic conditions. A subgroup of primary headache disorders, often refractory to other pharmacologic treatment such as triptans and the usual non-steroidal anti-inflammatories, was noted to be exquisitely and absolutely responsive to the analgesic effects of indomethacin. These disorders have been better characterized over the past decade and classified into primary headache disorders of paroxysmal hemicrania (PH) and hemicrania continua (HC). ⋯ More rarely, the development of new headaches have been reported in chronic indomethacin use. In these settings, other classes of medications such as selective cyclooxygenase-2 inhibitors (celecoxib), anti-epileptic agents (topiramate), calcium channel blockers (verapamil, flunarizine), melatonin, and local nerve blocks with anesthetic and steroids have been shown to be effective in case reports and series. We review the literature and provide our clinical recommendations on alternative therapies for the "indomethacin-responsive headaches".

ReviewTic versus TAC: differentiating the neuralgias (trigeminal neuralgia) from the cephalalgias (SUNCT and SUNA).
Trigeminal neuralgia, short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with autonomic symptoms (SUNA) are classified as distinct disorders in the International Classification of Headache Disorders 3 beta (ICHD-3 beta). SUNCT and SUNA are primary headache disorders included among the trigeminal autonomic cephalalgias. ⋯ The reported overlap among these conditions has called into question whether they should be considered distinct entities or rather a continuum of the same disorder. This review explores the known overlap and how other features not included in the ICHD-3 beta criteria may better differentiate the "Tics" (trigeminal neuralgia) from the "TACs" (SUNCT and SUNA).

Review Historical ArticleHistory and present state of targeted intrathecal drug delivery.
Nearly 50 years ago, the seminal experiments of Melzack and Wall, culminating in the gate control theory, coupled with the discovery of endogenous opioid receptors, helped shape modern understandings of pain and provided interventionalists a potent therapeutic gateway to neuraxial analgesia. This paper emphasizes the historical antecedents, present state, and emerging future of the neuromodulatory technique of targeted intrathecal drug delivery (TIDD) for chronic pain. The strengths of TIDD are its customizability, reversibility, programmability, and low risk profile. Its benefits are evidenced by improved pain relief and quality of life and reduced demand for health-care resources.

ReviewDiagnose and adios: practical tips for the ongoing evaluation and care of TAC patients taking indomethacin.
Paroxysmal hemicrania and hemicrania continua are primary headache disorders characterized by unilateral attacks of severe pain around the orbit with associated autonomic features. They are unique in their absolute response to indomethacin. ⋯ For patients who do not tolerate indomethacin, or wish to come off medication, there remain few options. This article will discuss the diagnosis of paroxysmal hemicrania and hemicrania continua and the ongoing management of patients on indomethacin, as well as options for patients who do not tolerate or need to come off indomethacin.
