ReviewOccipital injections for trigemino-autonomic cephalalgias: evidence and uncertainties.
Cluster headache is a debilitating disorder. Oral prophylactic treatments may act with a significant delay, cause side effects, or fail to control the attacks. Injections targeting the occipital nerve have raised interest for the management of CH. ⋯ Occipital injections provide a rapid benefit on the frequency of attacks and can be used as an adjunct to an oral prophylactic for a quicker improvement. Whether or not this approach can be used without any oral prophylaxis is still to be determined. The technique is easy to master, has a low cost, and should be learned by physicians involved in CH management.

ReviewManagement of trigeminal autonomic cephalalgias in children and adolescents.
Primary headache disorders that are more frequently encountered in the paediatric population include migraine and tension-type headaches. The trigeminal autonomic cephalalgias (TACs), which includes cluster headache (CH), paroxysmal hemicrania (PH) and short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT), are rarely reported in the paediatric population. The 1-year prevalence of CH seems to be 0.03 %. ⋯ The clinical phenotype and response to treatment seem to resemble the adult-onset form. Paediatric-onset TACs are poorly recognized and there is often a delay of several months or years before the diagnosis is made. Awareness of typical clinical pictures of these excruciating headaches is essential to allow prompt initiation of the appropriate management.

Neurostimulation techniques for the treatment of primary headache syndromes, particularly for chronic cluster headache (CCH), have received much interest in the recent years. Occipital nerve stimulation (ONS) has yielded favourable clinical results, and is becoming a routine treatment for refractory chronic cluster headache in specialized centres. Meanwhile, other promising techniques, such as spinal cord stimulation (SCS) or sphenopalatine ganglion stimulation, are emerging. This article reviews the current state of clinical research for neurostimulation techniques for chronic cluster headache, and particularly the pros and cons of SCS and ONS.

Animal-assisted therapy is a complementary medicine intervention, typically utilizing dogs trained to be obedient, calm, and comforting. Several studies have reported significant pain relief after participating in therapy dog visits. ⋯ Mirror neuron activity and disease-perception through olfactory ability in dogs may also play important roles in helping dogs connect with humans during therapeutic encounters. This review will explore a variety of possible theories that may explain the therapeutic benefits that occur during therapy dog visits.

ReviewMechanism of action of indomethacin in indomethacin-responsive headaches.
Indomethacin, as a member of the non-steroidal anti-inflammatory drug class, plays a special role in the treatment of headaches. By definition, it is completely efficacious in the treatment of the primary headache disorders paroxysmal hemicrania and hemicrania continua. Therefore, indomethacin is also used as a tool for differential diagnosis in headache clinics. ⋯ However, it is not known what mechanism or interaction with pathophysiological mechanisms is the key to indomethacin's specific pharmacology in headache therapy. Focusing on headache therapy, we summarize the current knowledge of pharmacology, treatment options, and recommendations for the use of indomethacin in primary headaches. New findings from the field of headache research, as well as from Alzheimer's disease and cancer research on the pharmacological actions of indomethacin and their potential implications on the pathophysiology of indomethacin sensitive headaches, are discussed.
