Late onset vulvar steatocystoma multiplex
No full textSteatocystoma multiplex is a rare, autosomal dominant condition characterized by multiple cysts, usually arising on the trunk and proximal extremities at puberty. We present two unrelated women with sporadic steatocystoma multiplex strictly confined to the vulva and arising at an older age. These cases represent an unusual localized form of the disorder
Measuring the activity of the disease in patients with cutaneous lupus erythematosus
No full textThe Systemic Lupus Activity Measure (SLAM) is a system proposed by rheumatologists to measure disease activity in their patients with systemic lupus erythematosus (LE). It involves scoring a group of clinical symptoms and laboratory findings, the maximum possible score being 84. In systemic LE, the mid-point is between 9 and 12. We applied SLAM to 176 patients with cutaneous LE. Ninety-seven had localized discoid LE (L-DLE), 59 had disseminated discoid LE (D-DLE) and 20 had subacute cutaneous LE (SCLE). Eighty-five patients had low activity disease (0-4 points), 72 mildly active disease (5-9 points), 15 moderately active disease (10-14 points) and only four had very active disease (>/= 15 points). The most frequent lesions in patients who scored more than 10 points were photosensitivity, cicatricial alopecia, Raynaud's phenomenon and oral ulcers. Fifty patients were followed up for more than 5 years (mean follow-up 9 years). Nine of these had an increased SLAM score. Seven had L-DLE, one D-DLE and one SCLE. Seven of the 50 patients had photosensitivity, five cicatricial alopecia, five non-cicatricial alopecia, two Raynaud's phenomenon and two oral ulcers. Three patients who started with L-DLE evolved to D-DLE. The SLAM system is useful in the monitoring of disease activity in patients with cutaneous LE. Over time, even L-DLE patients may develop active disease. Photosensitivity, alopecia, oral ulcers and Raynaud's phenomenon seem to herald a worse prognosis

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
