Efficacy of oxygen inhalation in sumatriptan refractory "high altitude" cluster headache attacks.
Full text linkWe describe the case of a 40-year-old woman, affected by episodic cluster headache, who presented with a cluster headache triggered by exposure to high altitude. Her attacks were refractory to sumatriptan, very effective at sea level, but responded to oxygen. A pathophysiological mechanism is proposed
MIGRALEPSY: A TOO NARROW DEFINITION?
No full textThe relationship between epilepsy and migraine is complex and remains to be determined. We report 3 cases that address 2 questions on this topic. The first and second cases showed an association between migraine without aura and the onset of epileptic seizures. The third case report describes a patient in whom migraine with aura occurred and was followed by the development of status epilepticus, which occurred 2 or 3 hours after the attack of migraine with aura. We discuss the present definition of migralepsy and reassess its definition by suggesting possible extensions to its current definition

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
