Cephalalgia : an international journal of headache

The aim was to apply diagnostic criteria, as published by the International Headache Society (IHS), to the diagnosis of orofacial pain. A total of 328 consecutive patients with orofacial pain were collected over a period of 2 years. The orofacial pain clinic routinely employs criteria published by the IHS, the American Academy of Orofacial Pain (AAOP) and the Research Diagnostic Criteria for Temporomandibular Disorders (RDCTMD). ⋯ In MMP the combination of facial pain aggravated by jaw movement, and the presence of three or more tender muscles resulted in a PPV = 0.82 and a NPV = 0.86. For NVOP the combination of facial pain, throbbing quality, autonomic and/or systemic features and attack duration of > 60 min gave a PPV = 0.71 and a NPV = 0.95. Expansion of the IHS system is needed so as to integrate more orofacial pain syndromes.

Acute and chronic whiplash headache are new diagnostic entities in the ICHD-2 (5.3, 5.4). In a prospective cohort study, 210 rear-end collision victims were identified consecutively from police records and asked about head and neck pain in questionnaires after 2 weeks, 3 months and 1 year. The results were compared with those of matched controls who were also followed for 1 year. ⋯ Previous headache was a major risk factor for headache both in the acute and chronic stage. Compared with the non-traumatized controls, headache in the whiplash group had the same prevalence, the same diagnoses and characteristic features, and the same prognosis. Both acute and chronic whiplash headache lack specificity compared with the headache in a control group, and have the same long-term prognosis, indicating that such headaches are primary headaches, probably elicited by the stress of the situation.

Whiplash is a controversial concept. The real nature and prevalence of whiplash-related headaches are not known. ⋯ The two last groups of patients had significantly less history of trauma in their medical records, with longer time span between the injury and the headache onset. Whiplash may induce preferably cervicogenic and tension-type headaches.

Migraine with aura (MA) is associated with changes in cerebral blood flow (CBF), whereas the role of cerebral autoregulation is uncertain. This study aimed to evaluate basal CBF, cerebral blood volume (CBV) and vasomotor reactivity (VMR) in MA patients. ⋯ These findings suggest altered autoregulation in MA patients, possibly secondary to impaired cerebrovascular autonomic control. Simultaneous TCD and NIRS investigation could represent a non-invasive approach to evaluate cerebral haemodynamics at the cortical and subcortical level.

We report on a female patient who developed post-dural puncture headache (PDPH) after epidural analgesia for delivery. Treatment with epidural blood patch led to complete headache remission and the patient was discharged. Two days later the patient was readmitted with hemihypaesthesia and mild hemiparesis of the right side. ⋯ Review of the literature revealed five patients in puerperal state, who developed CVT in close temporal relationship after blood patch treatment for PDPH. Change of headache character with loss of postural influence was reported frequently before diagnosis of CVT was confirmed. These findings may indicate a causal relationship.
