Cutaneous atrophy and alopecia after greater occipital nerve injection using triamcinolone.
Greater occipital nerve (GON) infiltration is widely used for the treatment of primary and secondary headache disorders mainly on the basis of open-label evidence, although recent double-blinded placebo-controlled trials have demonstrated its efficacy in cluster headache. The procedure is generally well tolerated although corticosteroid-related side effects, including Cushing's syndrome and local cutaneous changes, can occur. We report the occurrence of cutaneous atrophy and alopecia in 4 patients who underwent GON blockade with triamcinolone and lidocaine. Triamcinolone injection is associated with cutaneous atrophy, especially in superficial injection sites; therefore, alternative steroid preparations like methylprednisolone and betamethasone might be more appropriate for GON blockade.

Orbitofrontal cortex (OFC) dysfunction and poor decision making have been described in patients with chronic migraine and medication overuse. These neurobiological underpinnings might explain dependency-like behaviors often described in this condition, such as loss of control over painkillers, high rates of relapse after detoxification, and compromised social functioning. We investigate whether the OFC impairment was a persistent trait in migraine, independent of clinical and affective features, a dynamic result of the need to cope with the increased pain and disability, or a temporary consequence of medication overuse. ⋯ The present findings suggest the presence of a persistent OFC dysfunction in migraine as a psychobiologic trait that is not influenced by the presence of medication overuse, the clinical severity of the disease, or the patient's affective status. Further studies are needed to elucidate the etiopathological role of OFC in migraine and medication overuse.

To investigate the prevalence of medication overuse headache (MOH) in a group of children and adolescents seen for headache in a third-level center in Italy. ⋯ We believe that a strong warning regarding medication overuse in headache therapy is essential for pediatricians and neuropsychiatrists.
