ReviewElectroconvulsive therapy in the management of chronic pain.
Electroconvulsive therapy (ECT) is used predominantly to treat major depressive illness but has also been used for chronic pain. ECT causes a variety of neurochemical and neurophysiologic effects, some of which may interact with the pathophysiologic mechanisms in complex pain states. An extensive literature on the use of ECT in pain patients identifies subgroups for whom ECT may result in substantial pain relief. In this article, we review the literature on the use of ECT in pain patients, suggest possible neurobiologic bases for the efficacy of ECT in such patients, and conclude with our recommendations for current clinical practice.

Cluster headache is the most painful of the primary headache disorders and elucidating pathophysiology and treatment for this disorder is crucial. There is justification for studying attacks untreated, and even for precipitating these attacks. Placebo-controlled studies should only be undertaken for regulatory purposes; otherwise, active control should be used.

ReviewInterventional treatment for cluster headache: a review of the options.
There is no more severe pain than that sustained by a cluster headache sufferer. Surgical treatment of cluster headache should only be considered after a patient has exhausted all medical options or when a patient's medical history precludes the use of typical cluster abortive and preventive medications. ⋯ To understand the rationale behind the surgical treatment strategies for cluster, one must have a general understanding of the anatomy of cluster pathogenesis. The most frequently used surgical techniques for cluster are directed toward the sensory trigeminal nerve and the cranial parasympathetic system.

The design and execution of clinical trials poses special problems for cluster headache. Although there is less inter-individual and intra-individual variability of attacks than seen with migraine, the brevity of attacks, spontaneous remissions unrelated to treatment, and the relative rarity of cluster headaches challenge investigators. The International Headache Society has developed guidelines that represent a compromise between scientific rigor and practicality. Only injectable sumatriptan for acute attacks and verapamil for prophylaxis have demonstrated a robust therapeutic effect in controlled clinical trials.

ReviewThe psychopharmacologic treatment of depression and anxiety in the context of chronic pain.
Chronic pain afflicts millions of people, commonly causing depression and anxiety. These conditions must be treated to achieve a good functional outcome from pain treatment. ⋯ Antidepressants with noradrenergic and serotinergic activity, and anticonvulsants, which may also stabilize mood, are effective in neuropathic pain. Other medications have limited but important pharmacotherapeutic roles.
