Twenty-four out of 33 (73%) cases with Chiari 1 malformation complained of headache, and 9/33 (27%) of those patients (5 with mild and 4 with severe tonsillar ectopia) reported headache attributed to Chiari 1 malformation. In our studied pediatric population, the most common symptom for cases diagnosed with Chiari 1 malformation was headache, and headache attributed to Chiari 1 malformation was the most common headache pattern in patients with Chiari 1 malformation. The presence of headache attributed to Chiari 1 malformation along with 3 other signs or symptoms of Chiari 1 malformation were highly predictive of severe tonsillar ectopia. “

Background.— The serotonergic system is thought to play an important role for mediating susceptibility to migraine and depression, which is frequently found comorbid in migraine. The functional Bortezomib cell line polymorphism in the serotonin transporter gene linked polymorphic region (5-HTTLPR/SLC6A4) was previously associated with attack frequency and, thus, possibly with chronification.

Objective.— We hypothesized that patients with the “s” allele have higher attack frequency and, paralleling results in depression research, higher scores of depression. Methods.— Genetic analysis of the SLC6A4 44 bp insertion/deletion polymorphism (5-HTTLPR) was performed in 293 patients with migraine with and without aura. Self-rating questionnaires were used for assessment of depression. Results.— Multinomial logistic regression analysis found no evidence for association of the 5-HTTLPR polymorphism

Luminespib in vitro with either depression 上海皓元医药股份有限公司 or migraine attack frequency. Conclusion.— We were not able to demonstrate any influence of the serotonin transporter 5-HTTLPR polymorphism on migraine phenomenology (attack frequency or comorbid depression), thereby excluding this variant to be a common genetic denominator for chronic migraine and depression. “
“Wiley has updated its publishing ethics guidelines, first published in 2006. The new guidelines provide guidance, resources, and practical advice on ethical concerns that arise in academic publishing for editors, authors, and researchers, among other audiences. New guidance is also included on whistle blowers, animal research, clinical research, and clinical trial registration, addressing cultural differences, human rights, and confidentiality. The guidelines are uniquely interdisciplinary, and were reviewed by 24 editors and experts chosen from the wide range of communities that Wiley serves. They are also published in Advanced Materials, International Journal of Clinical Practice, Annals of the New York Academy of Sciences, Social Science Quarterly, and on the website http://exchanges.wiley.com/ethicsguidelines. “
