Randomized Controlled Trial
A comparison of selected osteopathic treatment and relaxation for tension-type headaches.
The objective of this study was to compare the effects of osteopathic treatment and progressive muscular relaxation (PMR) exercises on patients with tension-type headache (TTH). ⋯ The people in this study who did relaxation exercises and received 3 osteopathy treatments had significantly more days per week without headache than those who did only relaxation exercises.

Cluster headache (CH) is a rare but severe headache form with a distinct clinical presentation. Misdiagnoses and mismanagement among these patients are high. ⋯ Apart from the IHS criteria additional features like nausea/vomiting and migrainous aura may guide the diagnosis of CH. A large number of CH patients do not receive adequate treatments.

Occipital neuralgia has been attributed to lesions at a peripheral nerve or radicular level. On rare occasions, it has been associated with cervical cord lesions. We report a 55-year-old woman who presented with an isolated occipital neuralgia and was found on further investigation to have a restricted, isolated myelitis at C2 level. This represents the second reported case of occipital neuralgia due to C2 myelitis and should alert clinicians to considering cervical MRI in patients with occipital neuralgia.

We examined changes in the serotonin system across the estrous cycle in trigeminal ganglia of female rodents to determine which components are present and which are regulated by the variations in levels of ovarian steroids that occur during the estrous cycle. ⋯ In C57/BL6 mice mRNA levels of TPH-1, the rate-limiting enzyme in serotonin synthesis, were over 2-fold higher and protein levels were 1.4-fold higher at proestrus, the high estrogen stage of the cycle than at diestrus, the low estrogen stage. TPH protein also was present in primary trigeminal cultures obtained from female Sprague-Dawley rats, but levels were not affected by 24-hour treatment with physiological levels (10(-9) M) of 17beta-estradiol. Gene expression of 5HT-1B and 5HT-1D receptors in trigeminal ganglia was not regulated by the estrous cycle. Serotonin was present in trigeminal neurons containing CGRP, a potent vasoactive neuropeptide, peripherin, an intermediate filament present in neurons with unmyelinated axons, neurofilament H, which is present in neurons with myelinated axons, and in neurons binding IB4, a marker of nonpeptidergic nociceptors. Serotonin was also present in neurons containing 5HT-1B. The serotonin-positive population was significantly larger in diameter than the serotonin-negative population. Conclusions.-Expression of the rate-limiting enzyme required for serotonin synthesis is regulated during the natural estrous cycle, and serotonin is present in larger trigeminal neurons of all the major subtypes. Colocalization of serotonin with 5HT-1B suggests that this receptor functions as an autoreceptor to regulate serotonin release. Cyclical changes in serotonin levels in trigeminal ganglia could contribute to the pathogenesis of menstrual migraine.
