Actinic prurigo
No full textThe non-Native American type of actinic prurigo belongs to the group of rare idiopathic photodermatoses and therefore is often diagnosed with delay. The typical clinical and epidemiological features of actinic prurigo are described in a 10 year old girl. Detailed phototesting showed urticarial early onset and prurigo-like late onset reactions towards long-wave UVA. Repetitive photoprovocation with UVB induced delayed development of papules. HLA typing showed the typical association with HLA-DR4, in particular DRB1 0407. Treatment is usually extremely difficult and unrewarding. In this patient, the course was considerably improved by more intense physical photoprotection
Pledge-and-review in the laboratory
Get PDFWe perform a laboratory test of Pledge-and-Review bargaining, implementing a simplified version of the model analysed in Harstad (2021a). In theory, this institution should increase contributions to a public good only if there is uncertainty over the value of possible future payoffs. In contrast, we find that Pledge-and-Review increases efficiency in all the settings we investigate, and that the improvement is most persistent in our setting without uncertainty. Our results suggest that the Pledge-and-Review institution may be useful, even without uncertainty, as it allows conditional cooperators to test, risk free, the cooperativeness of their partners.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Shiitake (Lentinula edodes) dermatitis
No full textShiitake an edible asian mushroom nowadays becomes popular in european cooking, too. Allergic diseases to shiitake occur as contact dermatitis, alveolitis or asthma. Consuming of raw shiitake causes toxicodermia. Along with this disease papules develop. The polysaccharide lentina probably is the responsible toxin. Within seven months, we found three patients developing skin lesions after eating this mushroom. A 45 years old patient who often prepared and consumed meals containing shiitake, showed recurrent erythematous papules on his face. A prick to prick test with a shiitake mushroom showed an immediate converting into a delayed reaction. Two other patients developed skin eruptions after eating raw shiitake. One of them had eaten fried shiitake before without any problems. Prick to prick tests with Shiitake tamed out to be negative in both cases. At the side of testing, 24 hrs later a delayed reaction with severely itching papules developed. The first case is supposed to be an allergic reaction whether the two other cases may rather be a toxicodermia, because of their history and clinical symptoms. However, the positive skin tests in these two cases would suggest other possible mechanisms. Further studies are necessary to clarify theses different phenomenon

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
