To investigate bilateral widespread pressure pain hyperalgesia in deep tissues over symptomatic (trigemino-cervical) and nonsymptomatic (distant pain-free) regions in patients with cluster headache (CH). ⋯ Our findings revealed bilateral widespread pressure pain hypersensitivity in patients with CH confirming the presence of central sensitization mechanisms in this headache condition.
-
To review our experience with cervicomedullary junction spinal cord stimulation (SCS), to alleviate head and facial pain. ⋯ Our preliminary experience suggests that patients suffering from TDP, TNP, and PHN may respond favorably to CMJ-S whereas patients with occipital neuralgia/pain are rarely palliated by this neuromodulatory approach.

The neuropathic origin of a case of unilateral burning mouth syndrome, previously diagnosed as psychogenic, was ascertained by intra-oral mucosa biopsy, which showed a severe sensory fibers damage, probably caused by maxillary anesthetic block and dental surgery.
-
To determine whether the inhibitory effect of acute limb pain on pain to mechanical stimulation of the forehead is compromised in individuals with frequent episodes of tension-type headache. ⋯ These findings suggest that endogenous pain modulation processes are compromised in individuals with frequent episodic tension-type headache. This deficit could increase vulnerability to scalp tenderness and recurrent episodes of headache.

Over the years, there has been a considerable amount of controversy as to whether the vascular component of migraine pain arises from the intracranial or the extracranial vessels or both. Some have even questioned whether vasodilatation even plays a significant role in migraine pain and have described it as an unimportant epiphenomenon. In this review, evidence is presented that confirms (1) vasodilatation is indeed a source of pain in migraine; (2) this dilatation does not involve the intracranial vasculature; (3) the extracranial terminal branches of the external carotid artery are a significant source of pain in migraine.
