This article discusses the headache disorders associated with physical and sexual activity, highlighting their differences and similarities. The place of exertional and sexual headaches in the classification of the International Headache Society and in the proposed classification of Indomethacin-Responsive Headache Disorders is addressed here. The Valsalva's maneuver as a shared pathophysiologic mechanism is mentioned as well. ⋯ Sexual headaches are divided into three subtypes, based on the onset time, related to orgasm. The clinical characteristics of each type are presented, and their etiologies pointed out. The diagnostic approach is discussed, as well as the nonpharmacologic and pharmacologic treatment options.

ReviewNeuraxial infusion in patients with chronic intractable cancer and noncancer pain.
Ever since the application in 1980 of morphine for spinal analgesia in patients with refractory cancer pain, spinal infusion therapy has become one of the cornerstones for the management of chronic, medically intractable pain. Initially, spinal infusion therapy was indicated only for patients with cancer pain that could not be adequately controlled with systemic narcotics. However, over the past decade, there has been a significant increase in the number of pumps implanted for the treatment of nonmalignant pain. ⋯ Because of the difficulties associated with long-term intrathecal opiate therapy, much of the research, both basic and clinical, has focused on developing alternative nonopioid agents to be used either alone or in combination with opiates. Clinical trials have been and continue to be conducted to evaluate drugs such as clonidine, SNX-111, local anesthetics, baclofen, and many other less common agents to determine their efficacy and potential toxicity for intrathecal therapy. This article reviews the agents developed as alternatives to intrathecal opiates.

Spontaneous intracranial hypotension (SIH) is typically manifested by orthostatic headaches that may be associated with one or more of several other symptoms, including pain or stiffness of the neck, nausea, emesis, horizontal diplopia, dizziness, change in hearing, visual blurring or visual field cuts, photophobia, interscapular pain, and occasionally face numbness or weakness or radicular upper-limb symptoms. Cerebrospinal fluid (CSF) pressures, by definition, are quite low. SIH almost invariably results from a spontaneous CSF leak. ⋯ Although various treatment modalities have been implemented, epidural blood patch is probably the treatment of choice in patients who have failed an initial trial of conservative management. When adequate trials of epidural blood patches fail, surgery can offer encouraging results in selected cases in which the site of the leak has been identified. Some of the spontaneous CSF leaks are related to weakness of the meningeal sac, likely in connection with a connective tissue abnormality.

ReviewEffective management of ice pick pains, SUNCT, and episodic and chronic paroxysmal hemicrania.
Idiopathic stabbing headaches, the SUNCT syndrome, and the paroxysmal hemicranias are a group of primary headache disorders that are characterized by brief, short-lived attacks of head pain, which recur multiple times throughout the day. These syndromes are much less prevalent than other types of primary headaches such as migraine and tension-type headaches but are significantly more disabling. Recognition of these uncommon disorders is important because their management differs from standard headache therapies.

Most patients who have been diagnosed with cancer will experience pain at some point during the course of their disease. Often, opioid analgesics are not enough to completely alleviate the patient's pain and the selection of appropriate adjunct analgesic agents is critical. This article reviews the mechanisms of action and analgesic effects of several classes of antidepressants to enable the clinician to select the appropriate agent for the patient.
