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.

Chronic pains typically evaluated by a urologist are discussed from the perspective of a non-urologist pain clinician. The pathophysiology of some pains is understood and so we believe the patient's symptoms: examples are cancer-related pain and recurrent urolithiasis. ⋯ Other pains, such as those of interstitial cystitis, chronic prostatodynia, and chronic orchialgia are less understood and so are treated in a more conservative and often empiric fashion. Proposed therapies for these disorders are discussed.

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.

ReviewHypothalamic involvement and activation in cluster headache.
Cluster headache is an episodic form of primary neurovascular headache that is both severe and relatively rare. It is characterized by episodes of headache with cranial parasympathetic activation and sympathetic impairment that come in bouts, or clusters. Its pathophysiology can be divided into understanding the attack phenotype and the biotype of the periodicity. ⋯ This area is subtly enlarged in its gray matter volume, active during an acute cluster headache but inactive when patients are challenged between bouts. Cluster headache is likely to be a form of primary neurovascular pain whose phenotypic expression relies on the trigeminal-autonomic reflex, with a biotype determined by the brain area, the posterior hypothalamus, in which the lesion seems to be located. Understanding both the phenotypic expression and the biotype will, respectively, enable better acute attack treatments and better preventative management of this horrible form of headache.
