ReviewTreatment of chronic migraine headache with onabotulinumtoxinA.
Chronic migraine headache remains an exceedingly difficult entity to manage. Treatment of chronic migraine headache with onabotulinumtoxinA has recently been shown to be effective in reducing the severity and frequency of chronic migraine headache, in the PREEMPT trials, a landmark achievement. However, the studies use a primarily fixed dose and site approach to treatment, allowing some individualized injections. However, the authors do not address the issue of myofascial trigger points as potential triggers of migraine that could be inactivated using onabotulinumtoxinA, despite several studies that support the role of myofascial trigger points in initiating some migraine headaches.

Disordered sleep is such a prominent symptom in fibromyalgia that the American College of Rheumatology included symptoms such as waking unrefreshed, fatigue, tiredness, and insomnia in the 2010 diagnostic criteria for fibromyalgia. Even though sleep recording is not part of the routine evaluation, polysomnography may disclose primary sleep disorders in patients with fibromyalgia, including obstructive sleep apnea and restless leg syndrome. In addition, genetic background and environmental susceptibility link fibromyalgia and further sleep disorders. ⋯ The effect of exercise is contradictory, but overweight or obese patients with fibromyalgia should be encouraged to lose weight. Regarding the approved antidepressants, amitriptyline proved to be superior to duloxetine and milnacipran for sleep disturbances. New perspectives remain on the narcolepsy drug sodium oxybate, which recently was approved for sleep management in fibromyalgia.

Headache and endometriosis show some similarities in their clinical and epidemiological features that are probably due to the influence of female sexual hormones on both disorders. Epidemiological studies indicate that they are comorbid disorders. ⋯ A common link to the widespread use of estroprogestins may seem less probable. For physicians dealing with women with either of these disorders, awareness of the comorbidity may be helpful in the treatment of the patient.

The relation between sex hormones and migraine has been examined in a series of studies, leading to the definitions of pure menstrual migraine and menstrually-related migraine. The relation between sex hormones and other types of primary headache has been studied less extensively, but there is at least some evidence that hormones in general, and menstruation, pregnancy, or menopause in particular, also impact these disorders. This article reviews the available literature on changes of tension-type headache, cluster headache, other trigeminal autonomic cephalalgias, and hemicrania continua during women's reproductive periods.

Chronic pelvic pain is a complex condition that requires evaluation of the reproductive, gastrointestinal, urologic, musculoskeletal, psychological, and neurological systems. Usually, diagnosis and management entail identifying a network of disorders rather than a single cause of pain with a definitive cure. Only disorders that we commonly encounter in our practice will be discussed in this review.
