CPH and hemicrania continua: requirements of high indomethacin dosages an ominous sign?
No full textTwo female patients, one with chronic paroxysmal hemicrania and one with hemicrania continua, had a continuously high requirement of indomethacin, ie, > or = 225 mg per day, for 4 and 7 years, respectively. In the hemicrania continua patient, a right (symptomatic side) C7 root affection due to disc herniation was demonstrated. Removal of the disc relieved the arm pain completely, and reduced the head pain and indomethacin requirement considerably initially. The other patient suffered from the unremitting form of chronic paroxysmal hemicrania with right-sided attacks from the age of 16. Indomethacin, 200 to 250 mg per day generally kept the headache at bay, but during exacerbations, especially during menstrual periods, the dosage transitorily had to be increased to 250 to 350 mg per day. A CT scan with contrast at aged 18 (1987) was negative. In 1992, she started having new symptoms, including numbness on the ipsilateral side of the face and arm and difficulty swallowing. An MR scan showed a meningioma originating in the roof of the cavernous sinus on the symptomatic side. The meningioma was surgically removed. The postoperative indomethacin requirement was reduced, but only transiently. Patients with chronic paroxysmal hemicrania (CPH) and hemicrania continua (HC) with a continuously high indomethacin requirement may have grave additional disorders and should consequently be followed closely
Hemicrania continua: a clinical review
No full textHemicrania continua (HC) is a headache entity completely responsive to indomethacin. Since 1984, 18 cases have been described, 15 females and 3 males, i.e. a F:M ratio of 5.0. The finding of a female preponderance, like that in chronic paroxysmal hemicrania, is a new observation. HC is, in general, a unilateral headache in the sense that it sets in on one side and subsequently sticks to this side. In two cases, both sides might possibly be involved, when the pain was at its maximum. In another (somewhat dubious) case the headache was bilateral. The pain was continuous from the beginning in 8 of 18 cases (early stage ratio continuous: non-continuous = 0.8). Over time, the headache developed a continuous character in 16 of the 18 cases, producing a "continuous: non-continuous ratio" of 8:1. The intensity of pain generally was moderate and was not reported as excruciatingly severe by any patient. The autonomic involvement from a clinical point of view, was clearly less pronounced than that of other unilateral headaches, such as cluster headache and chronic paroxysmal hemicrania
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

No full textVariations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
