Education and decision making at the time of triptan prescribing: patient expectations vs actual practice.
Optimizing patient satisfaction with their medical care and maximizing patient adherence with treatment plans requires an understanding of patient preferences regarding education and their role in decision making when treatments are prescribed. ⋯ Based on this study, it is clear that patients prefer the shared model approach to medical decision making in regards to the prescription of triptans. The majority of patients received education that was generally consistent with their desires. Patients preferred that the prescribing provider be the primary source of information. The most desired educational topics included when/if a triptan should be taken, the number of times a triptan can be taken for a single migraine, co-administration with other acute medications, and the most common side effects. Focusing on these topics should enhance patient satisfaction and may improve compliance.

To report 2 cases of reversible cerebral vasoconstriction syndrome (RCVS) with posterior reversible encephalopathy syndrome (PRES) after blood transfusion for severe anemia. ⋯ RCVS with PRES is one complication of blood transfusion in patients under chronic severe anemia (especially when hemoglobin level increased for more than 5 g/dL), particularly in Asian women with menorrhagia. Blood pressure surge and the occurrence of severe headaches or other neurological symptoms should be aggressively monitored within 10 days after the last blood transfusion.

Recent genome-wide association studies (GWAS) have identified 3 genetic variants that are strongly associated with migraine in Europeans. The effect of these risk variants in other populations is unknown. To further replicate the GWAS findings, we investigated the 3 variants rs2651899 (1p36.32, PRDM16), rs10166942 (2q37.1, TRPM8), and rs11172113 (12q13.3, LRP1) for their association with migraine in the Chinese Han population. ⋯ Our study confirmed the association of PRDM16 to migraine susceptibility in the Chinese Han population. The results also indicated that replication studies of previous GWAS findings across populations is of importance to validate these associations and to gain a better understanding of migraine susceptibility of potential genetic heterogeneity between populations. Further work is necessary to understand the functional mechanisms underlying these variants identified by GWAS.
