Occipital Neuralgia in Chiari I Malformation: Two Different Events or Two Different Faces of the Same Event?

Occipital neuralgia (ON) is characterized by severe pain in the occipital region due to an irritation of the occipital nerves. Traumatic injuries, mass or vascular compression, and infective and inflammatory processes could cause ON. The dislocation of a nerve/muscle/tendon, as can happen in malformations such as the Chiari I malformation (CIM), also can be responsible.

Headache in immigrant patients: similarities and differences with Italian population.

Headache is one of the most common neurological diseases. It is well known that there are differences in the perception and in the management of pain in various populations. Immigrants represent a growing portion between neurology outpatients.

Association of RAMP1 rs7590387 with the risk of migraine transformation into medication overuse headache.

Objectives/background: We herein investigated the role of polymorphisms in calcitonin gene-related peptide (CGRP)-related genes looking at the association of rs3781719 (T > C) in the calcitonin gene-related polypeptide-alpha (CALCA) gene and of rs3754701 (T > A) and rs7590387 (C > G) at the receptor activity modifying 1 (RAMP1) locus with triptan response in patients with migraine without aura (MwoA). In addition, their role was evaluated as risk factors for transformation of episodic migraine into medication overuse headache (MOH). The CGRP has a central role in the pathogenesis of migraine; however, little information is currently available concerning the role of polymorphisms in CGRP-related genes as determinants of clinical response to anti-migraine drugs or as risk factors for migraine chronification.

Impaired visual inhibition in migraine with aura.

Objective: The pathophysiology of migraine with or without aura (MA, MO) is still a matter of debate. We thus studied patients with MA and MO by means of paired-pulse flash-visual evoked potentials (paired F-VEPs). This technique, recently revived, analyses the overall excitability of visual system as detected from the cortical occipital signal.
