Current pain and headache reports

Cluster headache has been defined by the International Headache Society (IHS) as one of the primary headaches. A primary headache is a headache that has no other known cause, such as infection or trauma. ⋯ The IHS has described cluster headache as "attacks of severe, strictly unilateral pain that is orbital, supraorbital, temporal or in any combination of these sites, lasting 15 to 180 minutes." In the author's practice, as a dentist treating orofacial pain, patients with cluster headache have dental or midfacial complaints as a primary presentation. This paper introduces such presentations based on interviews with cluster headache patients, with the main purpose of having midfacial complaints considered as an important presentation to be added to the IHS diagnostic criteria for cluster headache.

Review Case ReportsCluster headache: a case-based review of diagnostic and treatment approaches.
Cluster headache is one of the worst pain syndromes known to mankind. Medical treatment is highly effective in most cases, but because cluster headache is rare, many physicians are not familiar with the details of its management. This article reviews three common presentations of cluster headache to illustrate standard approaches to its treatment. Algorithms for acute, preventive, and transitional (bridge) therapy are provided.

Chronic pain is one of the frequently encountered clinical problems that is difficult to cure. Hyperbaric oxygen (HBO) therapy has been reported in chronic pain syndromes with promising results. In this review, we focus on the effectiveness of HBO in fibromyalgia syndrome, complex regional pain syndrome, myofascial pain syndrome, migraine, and cluster headaches. ⋯ However, physicians performing HBO must be aware of oxygen toxicity. Another problem regarding HBO is the scarcity of centers administering it. Further research is required focusing on the optimal treatment protocol, the cost/benefit ratio, and the safety of HBO in chronic pain management.

Serotonin (5-hydroxtryptamine, 5-HT) is an important molecule in pain processing and modulation. Whether 5-HT has an analgesic or hyperalgesic action depends on the cell type and type of receptor it acts on. ⋯ Furthermore, genetic alterations in the 5-HT system may influence the susceptibility to migraine. In the central nervous system, 5-HT is involved in descending inhibition, but facilitatory serotonergic pathways may be functionally more important.

Post-traumatic cluster headache (CH) is a very rare occurrence. Only one such case has been verified in the literature thus far. ⋯ Head trauma may damage extra- or intracranial peripheral or central nervous structures, hence predisposing to the future development of CH. However, there also is the possibility that previous head injuries may be more frequent among CH patients because of their lifestyle, which may leave them more exposed to the risk of traumatic events.
