Chronic paroxysmal hemicrania, hemicrania continua and SUNCT syndrome in association with other pathologies: a review.
No full textWe present a review of 22 cases of headache mimicking chronic paroxysmal hemicrania (CPH) (17 female and five male; F : M ratio 3.4), nine cases mimicking hemicrania continua (HC) (seven female and two male) and seven cases mimicking SUNCT syndrome (five male and two female) found in association with other pathologies published from 1980 up to the present. All case reports were discussed with respect to diagnostic criteria proposed by International Headache Society (IHS) for CPH, by Goadsby and Lipton for HC and SUNCT, and evaluated to identify a possible causal relationship between the pathology and the onset of headache. The aim of the present review was to evaluate if the presence of associated lesions and their location could help elucidate the pathogenesis of trigeminal autonomic cephalalgias (TACs)

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
