A curious case of opticneuritis in hidradenitis suppurativa patient, successfullytreated with adalimumab
Background: Hidradenitis suppurativa (HS), also known as acne inversa,
is a chronic inflammatory skin disease characterized by painful,
deep-seated
inflammatory nodules and abscesses appearing in
intertriginous regions of the body.
Objectives, Methods, Results and Conclusion: HS is associated
with other systemic inflammatory or autoimmune diseases, such as
Crohn’s disease, spondyloarthropathy, and Adamantiades-Behcet’s
disease. Recent case reports have documented the coexistence of
HS and inflammatory eye disease (IED), probably due to a common
immune dysregulation phenomenon. We present a case of optic
neuritis in HS patient, successfully treated with Adalimumab
Postacne scarring. Which factors are involved?
Post acne scars are a frequent late complication of the disease. The factors that underlie their clinical heterogeneity and severity have not yet been clarified.2 The studies conducted on this topic are few and dated.2,3 Post acne scars can be particularly devastating and may even trigger suicidal ideation.4 Depending on tissue response to inflammation we can define two general types of acne scars: hypertrophic scars caused by increased tissue formation and atrophic scars caused by the loss of tissue. Both types of acne scars can be divided in 4 grades according to Goodman and Baron qualitative grading system
Adult acne versus adolescent acne. A rtrospective study of 1,167 patients
Background: Acne is predominantly known as a skin disorder of the adolescent population. However, current research indicates that the prevalence of adult patients with acne, especially among women, is increasing. Objective: The objective of this study was to evaluate differences between adults and teenagers with regard to acne prevalence, patient sex, acne severity, and quality of life. In adult patients, we considered differences in family history of acne, onset, and smoking habits. Design: We performed a retrospective study of a total of 1,167 patients with acne who attended our outpatient clinic from January 2008 to March 2015. Participants: The study population was divided into two groups: adolescent acne and adult acne. Among the adult subjects, 385 were female and 69 were male; among the adolescent subjects, 378 were female and 335 were male. Measurements: The severity of acne was recorded using the Global Acne Grading System. The impact of acne on quality of life was investigated using the Assessment of Quality of Life questionnaire. Results: Study results show that acne in female patients was more prevalent than in male patients. The evaluation of acne severity showed that "mild acne" is the most frequent form. With regard to smoking habits, time of onset, and family history of acne, we did not find any statistically significant differences between the sexes. Conclusion: In both sexes, there are some differences in adult acne versus the adolescent form. Treating adult acne demands a different approach to diagnosis and a tailored management plan that considers all of the variables involved

PSSD and biologic therapy: real-life data in 417 patients with moderate to severe psoriasis
Background: Psoriasis is a chronic relapsing immune-mediated disease leading to a strong impact on patient's quality of life. The treatment of psoriasis has undergone a revolution with the advent of biological therapies. Currently, Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) scores are in use to assess the overall severity of pathology. A new self-administered questionnaire, the Psoriasis Symptoms and Signs Diary (PSSD), assesses the severity of six psoriasis symptoms (itch, skin tightness, burning, stinging, and pain,) and five signs (dryness, cracking, scaling, shedding/flaking, redness, and bleeding). Objective: To evaluate and compare the efficacy of biologic therapies through PSSD in patients with moderate to severe psoriasis. Methods: The PSSD questionnaire was administered to all the patients at the beginning and after 6 months of biologic therapy (anti-TNFalpha, anti-IL17, anti-IL23, anti-IL12/23 and phhosphodiesterase-4 Inhibitors). Results: The study population included 417 adult patients with moderate to severe psoriasis in treatment with biologic drugs. All the drugs contributed to a significant improvement in mean total PSSD at t 24; anti-IL17 and anti-IL23 led to a significantly greater reduction at t 24 mean PSSD when compared to other therapies. Conclusion: The PSSD, is a new validated instrument useful for capturing psoriasis patient's quality of life and evaluating treatment efficacy. In our study, this score has been useful to put in evidence significant differences between biological drugs
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Variations on the Author
“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
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
We 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
