Intranasal Ketamine for Abortive Migraine Therapy in Pediatric Patients: A Single-Center Review.

BACKGROUND: Ketamine has recently emerged as a promising therapeutic alternative for abortive migraine therapy, likely secondary to N-methyl-d-aspartate antagonism. Most reports examine adults and the intravenous route. Fewer utilize intranasal administration or pediatric populations. Given the limited evidence for intranasal ketamine in pediatric migraine populations, we retrospectively reviewed our experience to further characterize safety and efficacy of intranasal ketamine in this population. METHODS: A retrospective review in a free-standing, pediatric medical center was performed examining the utilization of intranasal ketamine at 0.1 to 0.2 mg/kg/dose up to five doses in pediatric migraineurs. Pain scores (scale = 0 to 10) were recorded at baseline and after each dose. Response was characterized as pain score reduction to 0 to -3 and/or reduction of at least 50%. RESULTS: Twenty-five encounters (25 of 34; 73.5%) were responders (mean pain score reduction of -7.2 from admission to treatment completion). Overall pain reduction from admission to discharge in the entire study population was 66.1%. Side effects were mild and transient. CONCLUSIONS: Our experience with intranasal ketamine has promising outcomes in both pain relief and side effect minimization. When other therapeutic options are unavailable, practitioners should consider intranasal ketamine.

Effect of fish oil supplement administration method on tolerability and adherence: a randomized pilot clinical trial.

OBJECTIVES: Anecdotally, several strategies have been suggested in order to improve tolerability of fish oil supplements, but there is little evidence supporting any of these strategies. The aim of this study was to determine if there is a difference among four methods of oral administration of fish oil supplementation in terms of tolerability and adherence. METHODS: A randomized, prospective, open-label, four-arm pilot study was conducted on 60 healthy adult subjects randomized to different fish oil supplement administration methods with (1) milk, (2) food, (3) an empty stomach, and (4) frozen capsules prior to ingestion. Each subject was instructed to take two capsules three times daily for 30 consecutive days. Adherence was assessed by pill counts. Adverse effects were assessed by survey and patient exit interview. RESULTS: No apparent differences were demonstrated among the four administration groups in terms of adherence, reasons for non-adherence, or self-reported adverse effects. CONCLUSIONS: Method of administration did not affect rates of adherence or incidence of adverse effects in a small cohort of healthy adults taking fish oil supplement capsules for 30 days. TRIAL REGISTRATION: ClinicalTrials.gov NCT01471366. Registered November 16, 2011.

Outside the box: Medications worth considering when traditional antiepileptic drugs have failed.

PURPOSE: Review and discuss medications efficacious for seizure control, despite primary indications for other diseases, as treatment options in patients who have failed therapy with traditional antiepileptic drugs (AEDs). METHODS: Literature searches were conducted utilizing PubMed and MEDLINE databases employing combinations of search terms including, but not limited to, "epilepsy", "refractory", "seizure", and the following medications: acetazolamide, amantadine, bumetanide, imipramine, lidocaine, verapamil, and various stimulants. RESULTS: Data from relevant case studies, retrospective reviews, and available clinical trials were gathered, analyzed, and reported. Experience with acetazolamide, amantadine, bumetanide, imipramine, lidocaine, verapamil, and various stimulants show promise for cases of refractory epilepsy in both adults and children. Many medications lack large scale, randomized clinical trials, but the available data is informative when choosing treatment for patients that have failed traditional epilepsy therapies. CONCLUSIONS: All neurologists have encountered a patient that failed nearly every AED, diet, and surgical option. For these patients, we often seek fortuitous discoveries within small series and case reports, hoping to find a treatment that might help the patient. In the present review, we describe medications for which antiepileptic effect has been ascribed after they were introduced for other indications.
