Medication overuse headache (MOH) is the most prevalent chronic headache disorder with a prevalence between 1% and 2% worldwide. The disease has been acknowledged for almost 30 years, yet experts still disagree on how best to treat MOH. By performing a search in PubMed on the terms "medication overuse headache," "analgesics abuse headache," "rebound headache," "drug induced headache," and "headache AND drug misuse" limited to human studies published in English between January 1, 2004, and November 1, 2017, we aimed to evaluate current literature concerning predictors of treatment outcome, inpatient and outpatient treatment programs, initial versus latent administration of prophylactic medications, and to review the effect of prophylactic medications. ⋯ We conclude that detoxification programs are of great importance in MOH treatment. Latent administration of prophylactic medications reduces the number of patients needing prophylactic medication. Individualizing treatment according to the predictors of outcome may improve treatment outcome and thus reduce work-related and treatment-related costs.

Multicenter Study Comparative StudyComparison of plasma and cerebrospinal fluid neurofilament light in a multiple sclerosis trial.
The main objective of this study was to evaluate the axonal component neurofilament light protein (NFL) in plasma and cerebrospinal fluid (CSF) as an outcome measure in a clinical trial on disease-modifying treatments in multiple sclerosis. ⋯ This study indicates that NFL in plasma is less sensitive as an endpoint in group comparisons than NFL in CSF. Given that plasma NFL is far easier to access, it is a promising and awaited method but further studies are needed to optimize the use in clinical trials.

Observational StudyTherapeutic drug monitoring of gabapentin in various indications.
Gabapentin has been increasingly used in various indications in recent years. Despite variable pharmacokinetics, therapeutic drug monitoring (TDM) is scarcely described in other indications than epilepsy. The aim of the study was to investigate the use and pharmacokinetic variability of gabapentin in epilepsy and non-epilepsy indications and to further evaluate the use of TDM in patients with restless legs syndrome (RLS). ⋯ Due to extensive pharmacokinetic variability, TDM can benefit patients using gabapentin. Challenges with applying TDM in new indications such as RLS include different dosage regimens and consequently different interpretation of serum concentrations. Thus, TDM should be requested on clear clinical grounds and the service tailored according to the therapeutic indication.
