Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) are rare and often disabling primary headache disorders. Their management can be challenging. The abortive therapies are not generally useful as the attacks are relatively short lasting. ⋯ For medically intractable chronic forms of SUNCT and SUNA, several surgical approaches have been tried. These include ablative procedures involving the trigeminal nerve or the Gasserian ganglion, microvascular decompression of the trigeminal nerve, and neurostimulation techniques. This review provides an overview of the current pharmacological and surgical options for SUNCT and SUNA syndromes.

Headache may occur in neurosarcoidosis and diagnostic criteria are given in the International Classification of Headache Disorders (ICHD-II). We present a case series of patients suffering from neurosarcoidosis in whom headache was the presenting symptom. The aim of the present study was to analyze the possible clinical presentations and the corresponding cerebral lesions in a retrospective chart review of patients suffering from neurosarcoidosis in whom headache was the presenting symptom. ⋯ In the remaining three cases headache was the only neurological symptom found in association with systemic features of sarcoidosis, and had the clinical features of tension-type headache. Our findings confirm that the clinical features of headache in patients with this disorder may have different presentations, which depend on neuropathologic involvement. Thus, a detailed neuroimaging study and CSF evaluation are needed to confirm diagnosis, particularly in patients with no sign of systemic sarcoidosis or in those in whom head pain may mimic a primary headache syndrome.

Migraine might be associated with high blood pressure (BP), which can cause more severe and more difficult to treat forms of headache. To evaluate the efficacy of frovatriptan and other triptans in the acute treatment of migraine, in patients classified according to a history of arterial hypertension, enrolled in three randomized, double-blind, crossover, Italian studies. Migraineurs with or without aura were randomized to frovatriptan 2.5 mg or rizatriptan 10 mg (study 1), frovatriptan 2.5 mg or zolmitriptan 2.5 mg (study 2), frovatriptan 2.5 mg or almotriptan 12.5 mg (study 3). ⋯ No difference in tolerability was reported between HTs and NTs. In conclusion, HT individuals tend to be less responsive than NT migraineurs to triptan therapy. However, frovatriptan, in contrast to other triptans, seems to have a sustained antimigraine effect in both HT and NT patients.

Migraine with aura (MWA) is a common headache, characterized by short-lasting neurological signs preceding an headache attack with migraine characteristics. We have recently performed several investigations about time-delay for migraine without aura diagnosis (MWoA). Aim of this study was to compare the time necessary to obtain a correct diagnosis in MWA and MWoA patients. ⋯ In fact, subjects affected by MWA had a mean diagnostic delay of 6.70 years (SE ± 1.5), while patients affected by MWoA had a mean interval of 10.7 years (SE ± 1.20). Patients affected by MWA present a significant lower delay for the formulation of a correct diagnosis with respect to subjects with MWoA. This could be probably due to the fact that MWA patients develop major alarm reactions related to visual symptoms and look for an earlier appointment with a specialist medical center.

Primary stabbing headache (PSH) is a primary syndrome of unknown aetiology, characterised by brief, jabbing stabs predominantly felt in the orbital, temporal and parietal areas, whose frequency may vary from one to many per day, usually responding to indomethacin. PSH frequency in the general population is not well defined, but recent evidence suggests it could be more frequent than previously thought. In clinical series, PSH incidence was 33/100,000 per year, while in a population study 35.2 % prevalence was found. ⋯ Seven out of eight patients responded to indomethacin 75 mg/die, and one to topiramate 100 mg/die. Interestingly, both drugs share with acetazolamide a CSF pressure lowering effect. Our findings indicate that PSH is associated with central sinus stenosis and suggest that an undiagnosed ss-IHWOP might be involved in PSH pathogenesis.
