We present a prospective 4-year follow-up study of 96 patients with medication overuse headache following withdrawal. Complete datasets were available from 85 patients (89%) 6 months, from 79 patients (82%) 1 year and from 75 patients (78%) 4 years after withdrawal. Twenty-six patients (31%) relapsed within the first 6 months after withdrawal. The number of relapses increased to 32 (41%) 1 year and to 34 (45%) 4 years after withdrawal. The 4-year relapse rate was lower in migraine than in tension-type headache (32% vs. 91%, P

While the prevalences of migraine and tension-type headache are comparable with those in Europe and the United States, a remarkably high percentage of the population of Georgia have headache on >/=15 days/month. This study demonstrates the importance of socioeconomic factors in a developing country and unmasks the unmet needs of people with headache disorders.

The pronounced neurotoxicity of the potent antitumor drug cisplatin frequently results in the onset of peripheral polyneuropathy (PNP), which is assumed to be initially triggered by platination products in the nuclear DNA of affected tissues. To further elucidate the molecular mechanisms, we analyzed in a mouse model the formation and processing of the main cisplatin-induced DNA adduct (guanine-guanine intrastrand cross-link) in distinct neuronal cell types by adduct-specific monoclonal antibodies.

We present the first questionnaire in German language including 3 most common primary headaches for use in epidemiological research.

Background and Purpose-Strokes have especially devastating implications if they occur early in life; however, only limited information exists on the characteristics of acute cerebrovascular disease in young adults. Although risk factors and manifestation of atherosclerosis are commonly associated with stroke in the elderly, recent data suggests different causes for stroke in the young. We initiated the prospective, multinational European study Stroke in Young Fabry Patients (sifap) to characterize a cohort of young stroke patients. Methods-Overall, 5023 patients aged 18 to 55 years with the diagnosis of ischemic stroke (3396) *Drs Rolfs, Fazekas and Grittner contributed equally to this work. Authors contributions: Dr Rolfs has conceptualized, initiated, and designed and organized the study, has been involved in the recruitment of the patients, and wrote significant parts of the manuscript. Dr Fazekas was involved in the study planning and has done together with Drs Enzinger and Schmidt the analysis of all MRI scans; this group was mainly involved in the statistical analysis of the MRI data. Drs Martus, Grittner, Holzhausen have taken responsibility for all statistical analysis and for the data structure of the total data bank. Drs Dichgans, Böttcher, Tatlisumak, Tanislav, Jungehulsing, Putaala, Huber, Bodechtel, Lichy, Hennerici, Kaps, Meyer, Kessler have been most active in the recruitment of the patients, drafting the manuscript and significantly influencing the scientific discussion. Dr Heuschmann was involved in drafting the manuscript and influencing the scientific discussion. Dr Norrving chaired the steering and publication committees of sifap, has written parts of the manuscript, and has significantly influenced the scientific discussions. Drs Lackner and Paschke, H. Mascher, Dr Riess have been involved in the laboratory analyses. Dr Kolodny has mostly contributed to the discussion of the Fabry cases. Dr Giese assisted in writing and editing the manuscript. All authors have reviewed, critically revised and approved the final version of the manuscript.The sponsors of the study had no role in the study design, data collection, data analysis, interpretation, writing of the manuscript, or the decision to submit the manuscript for publication. The academic authors had unrestricted access to the derived dataset, and assume full responsibility for the completeness, integrity, and interpretation of the data, as well as writing the study report and the decision to submit for publication.†Listed in Appendix I in the online-only Data Supplement.
