Patients with chronic headache had a high prevalence of sleep complaints. Insomnia may thus represent an independent risk factor for headache chronification. Recognition of sleep disorders, alone or in association with depression or anxiety, may be useful in episodic headache patients to prevent chronification.
The significantly increased familial risk for CH, drug overuse, and substance abuse suggests that a genetic factor is involved in the process of headache chronification.
Chimeric antigen receptor (CAR) T-cell therapy is an emerging highly effective treatment for refractory haematological malignancies. Unfortunately, its therapeutic benefit may be hampered by treatment-related toxicities, including neurotoxicity. Early aggressive treatment is paramount to prevent neurological sequelae, yet it potentially interferes with the anti-cancer action of CAR T-cells. We describe four CAR T-cells infused patients who presented with reiterative writing behaviours, namely paligraphia, as an early manifestation of neurotoxicity, and eventually developed frontal predominant encephalopathy (one mild, three severe). Paligraphia may represent an early, specific, and easily detectable clinical finding of CAR T-cell therapy-related neurotoxicity, potentially informing its management.
BackgroundDrug withdrawal still remains the key element in the treatment of Medication Overuse Headache (MOH), but there is no consensus about the withdrawal procedure. Still debated is the role of the steroid therapy. The aim of this study was to evaluate the effectiveness of methylprednisolone or paracetamol in the treatment of withdrawal headache in MOH.MethodsWe performed a pilot, randomized, single-blinded, placebo controlled trial. MOH patients, unresponsive to a 3 months prophylaxis, underwent withdrawal therapy on an inpatient basis. Overused medications were abruptly stopped and methylprednisolone 500 mg i.v (A) or paracetamol 4 g i.v. (B) or placebo i.v. (C) were given daily for 5 days. Patients were monitored at 1 and 3 months.ResultsEighty three consecutive MOH patients were enrolled. Fifty seven patients completed the study protocol. Nineteen patients were randomized to each group. Withdrawal headache on the 5th day was absent in 21.0% of group A, in 31.6% of group B and in 12.5% of group C without significant differences. Withdrawal headache intensity decreased significantly after withdrawal without differences among the groups. Rregardless of withdrawal treatment, 52% MOH patients reverted to an episodic migraine and 62% had no more medication overuse after 3 months.ConclusionsThis study suggests that in a population of severe MOH patients, withdrawal headache decreased significantly in the first 5 days of withdrawal regardless of the treatment used. Methylprednisolone and paracetamol are not superior to placebo at the end of the detoxification program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
