Cluster headache is an uncommon yet well-defined neurovascular syndrome occurring in both episodic and chronic varieties. The most striking feature of cluster headache is the unmistakable circadian and circannual periodicity. Inheritance may play a role in some families. ⋯ Transitional prophylaxis involves the short-term use of either corticosteroids or ergotamine derivatives. The cornerstone of maintenance prophylaxis is verapamil, yet methysergide, lithium, and divalproex sodium may also be employed. In some patients, melatonin or topiramate may be useful adjunctive therapies.

ReviewGender differences and hormonal modulation in visceral pain.
Women seek healthcare and are diagnosed more frequently with chronic somatic and visceral pain conditions relative to men. These conditions tend not to be life-threatening disorders, but rather ones that decrease people's quality of life, impinge on work and recreational activities, and increase healthcare resource utilization. With increased awareness of basic gender differences in biology and responsiveness to therapies, there has been renewed interest in factors which may account for the gender disparity in chronic visceral pain conditions. Basic and clinical evidence primarily from patients with irritable bowel syndrome has provided initial insights into visceral pain sensitivity, perception, and responsitivity.

Patients with chronic pelvic pain are usually evaluated and treated by gynecologists, gastroenterologists, urologists, and internists. In many patients with chronic pelvic pain the examination and work-up remain unrevealing and no specific cause of the pain can be identified. In these cases it is important to recognize that pain is not only a symptom of pelvic disease, but that the patient is suffering from a chronic pelvic pain syndrome. ⋯ This article outlines treatment options currently available. Despite the challenge inherent in the management of chronic pelvic pain, many patients can be treated successfully using a multidisciplinary pain management approach. The first important step is to recognize that patients with chronic pelvic pain might suffer from a chronic visceral pain syndrome.

Cluster headache is one of the most excruciating headaches affecting human beings--especially the male sex. Most of the cluster headache cases are of episodic nature, with active cluster periods lasting generally between a few weeks and 2 or 3 months. A still undetermined percentage of patients report nonpainful sensations preceding the onset of the pain attack for a variable period of time. ⋯ When occurring for several days, weeks, or months before the pain, they are termed premonitory symptoms. The author believes that premonitory symptoms have not been properly diagnosed and emphasizes the need to investigate their presence, because by knowing them advances can be made in the understanding of the physiopathology of this particular cephalalgia. Furthermore, it can also allow the physician to be ahead, by giving preventive treatment and stopping or diminishing the intensity and duration of the pain attacks.

Cluster headache is a rare, clinically well-characterized disabling disorder that occurs in both episodic and chronic forms. The very painful short-lived unilateral headache attacks are associated with autonomic dysfunction. A large number of drugs such as ergotamines, steroids, methysergide, lithium carbonate, verapamil, valproate, capsaicin, leuprolide, clonidine, methylergovine maleate, methylphenidate, and melatonin are considered beneficial for prophylaxis. ⋯ One of these was also given verapamil. Three of the 16 patients had an additional cluster period, which cleared with a second course of baclofen. In this pilot study, baclofen seemed to be effective, safe, and well tolerated for cluster headache, and seemed to retain its efficacy on repeated clusters.
