Eligibility criteria that result in the exclusion of a substantial number of patients from randomized trials jeopardize the generalizability of treatment effect to much of the clinical population. This is important when evaluating opioid substitution and antagonist therapies (OSATs), especially given the challenges associated with treating the opioid-dependent population. We aimed to identify OSAT trials' eligibility criteria, quantify the percentage of the clinical population excluded by these criteria, and determine how OSAT guidelines incorporate evidence from these trials. ⋯ Trials assessing OSATs often exclude patients with concurrent disorders. If the excluded patients respond differently to treatment, results from these trials are likely to overestimate the true effectiveness of OSATs. North American guidelines should consider these limitations when drafting clinical recommendations.

There is significant variability in the severity of neonatal abstinence syndrome (NAS) due to in-utero opioid exposure. We wanted to determine if single nucleotide polymorphisms (SNPs) in key candidate genes contribute to this variability. ⋯ These findings suggest that SNPs in opioid receptor and the PNOC genes are associated with NAS severity. However, further testing in a large sample is warranted. This has important implications for prenatal prediction and personalized treatment regimens for infants at highest risk for severe NAS.

To educate physicians about appropriate acute migraine treatment guidelines by determining (1) where headache patients were first prescribed opioids and barbiturates, and (2) the characteristics of the patient population who had been prescribed opioids and barbiturates. ⋯ Approximately 20% of patients presenting to a headache center reported current use of opioids and/or barbiturates. ED physicians were reported to be the most frequent first prescribers of opioids and general neurologists were the most frequent first prescribers of barbiturates. Taken as a whole, these data provide a useful snapshot of the wide variety of physician specialties that might benefit from additional education on the appropriate use of opioids and barbiturate-containing medications in patients with headaches.
