Narrowband UVB phototherapy for pediatric generalized pityriasis lichenoides.
No full textFrom our data and literature review, phototherapy emerges as an important therapeutic option for Pytiriasis Lichenoides – effective, well tolerated by the child, and with few side effects– and should be considered a first-line therapy, especially in generalized cases.
Additional data, especially from studies performed to compare other treatments with phototherapy, as well as from studies about maintenance therapies, are needed
Data Streaming and its Application to Stream Processing: Tutorial
No full textIn this tutorial paper we present the results of recent research findings in the area of data streaming applied to stream processing systems. In particular, we introduce the data streaming model, detailing the main algorithmic results in this research field. We then move to detail how such algorithms can be applied to modern distributed stream processing systems to improve their efficiency. Finally we outline several open research directions in this field
Long-term remission of erythrodermic mycosis fungoides after persistent control of hepatitis B infection
No full textImmunogenetic factors in mycosis fungoides: can the HLA system influence the susceptibility and prognosis of the disease? Long-term follow-up study of 46 patients.
No full textMycosis fungoides (MF) is the most common and one of the least aggressive forms of cutaneous T-cell lymphoma. Several studies have demonstrated the influence of human leucocyte antigen (HLA) genes on the susceptibility of MF, highlighting the importance of certain alleles but, until today, no studies have evaluated the relationship between HLA alleles and the prognosis of patients with MF.The aim of this retrospective cohort study was to evaluate the polymorphism of HLA class I and class II alleles in a group of 46 MF Caucasian patients, looking for their influence in susceptibility and prognosis of the disease.Study population included a case-cohort sample of 46 Caucasian patients with MF that, between 1993 and 1997, underwent HLA class I and II genomic typing. All patients were diagnosed and followed up from 1977 to 2012 (mean follow-up of 11 years) and they were divided into three groups according to the evolution of the disease.Molecular typing at low-resolution level revealed that HLA-A*24, A*68, A*69, B*35 and DQB1*05:02 alleles were involved in susceptibility to MF. Correspondence analysis underlined that long-lasting remission was characterized by HLA-A*24 and HLA-A*25 alleles, frequent relapse by HLA-DRB1*01, DQA1*01:01, DQB1*05:01 alleles and death by HLA-A*68, HLA-B*08, HLA-B*35, HLA-C*03 alleles.This study suggests that the prognosis of MF patients is not only correlated with clinical/pathological/serological/immunological variables but it also relies on specific HLA alleles
Recurrence of Mycosis Fungoides on Multiple Melanocytic Nevi: A Case Report and Review of the Literature
No full textMelanocytic nevi represent a widespread cutaneous finding. Nevertheless, the presence of mycosis fungoides and melanocytic nevi in the same location is an extremely rare event. We report the case of a patient affected by mycosis fungoides and treated with PUVA therapy, with complete remission of the disease. Eight years after therapy discontinuation, he presented epidermal scaling and an erythematous perinevic halo on 3 old melanocytic lesions, the clinical aspect of which was highly suggestive for Meyerson nevi. The histological and immunohistochemical examination of an excised melanocytic lesion revealed histological features consistent with the diagnosis of mycosis fungoides superimposed on junctional melanocytic nevi. The finding of patches of mycosis fungoides superimposed on melanocytic nevi is a rare event; the confounding clinical appearance with eczematous changes around a pre-existing nevus may recall the halo dermatitis known as Meyerson phenomenon; this highlights the importance of clinical and histological examination to make the correct diagnosis of dermatological diseases

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
Variations 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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
