Loss of efficacy during long-term infliximab therapy for sight-threatening childhood uveitis
No full textObjective. To describe efficacy and safety of infliximab in the treatment of childhood chronic uveitis during a long-term follow-up. Methods. Fifteen patients (median age 12 yrs, range 5-21 yrs) with chronic uveitis were enrolled. Before infliximab treatment, children had presented active uveitis despite treatment with MTX and/or CSA. All were also receiving oral prednisone (1-2 mg/kg/day) for at least 1 month. Infliximab (5 mg/kg) was administered at weeks 0, 2, 6 and then every 6-8 weeks. Later on, in patients enrolled in Florence the administration interval was progressively increased up to 10 weeks if uveitis did not flare, whilst in children from Padua the scheduled infusion rate was maintained every 6 weeks. Absence or recurrence rate of uveitis up to the last visit was recorded. Results. Median follow-up on treatment was 30 months (range 16-38 months), median number of infusions 22 (range 11-30). During the first year, 13/15 children achieved a complete remission over a median period of 10 weeks, but all relapsed thereafter. The probability of a first relapse was correlated to length of treatment, once remission was achieved (P < 0.03). The total number of relapses correlated with the duration of treatment (rs = 0.81; P < 0.002) and with the total number of infusions (rs = 0.83; P = 0.001). The total number of relapses on treatment at last follow-up was not significantly different between the two centres. Conclusions. Even if limited to a small group, infliximab appears to be an effective treatment for uveitis in children, but its efficacy seems to wane over time. © The Author 2008.

Complementary and alternative medicine (CAM) in paediatric rheumatology: A European perspective
No full textObjective: To analyse the use of complementary and alternative medicine (CAM) in children with rheumatic diseases, treated at a paediatric rheumatology centre in Italy. Methods: Parents of children with different kinds of chronic rheumatic diseases anonymously completed a questionnaire about their children's past or current use of CAM. Two groups of patients were analysed: Group A consisted of children who were still attending the centre; Group B consisted of children who had not attended the clinic for more than one year. Results: 150 completed surveys were analysed: 22 paediatric patients (14.7%), 10/100 in group A and 12/50 in group B, used CAM to treat their diseases. The therapies used the most were homeopathy, herbal remedies, vitamins and minerals. We observed a significantly greater use of CAM among patients who had not attended the clinic for more than one year (24%) as compared to those who were regularly checked (10%) (p=0.02). Parents' use of CAM was significantly related to its use for their children (p=0.001). A poor outcome, probably related to the exclusive use of alternative treatments, was observed in three out of six patients who had completely stopped using traditional immunosuppressive drugs. Conclusions: Physicians should be aware of the use of CAM particularly in patients who skip their regular check-ups. The use of CAM to treat childhood rheumatic conditions in Italy seems to be less frequent than in North America. © Clinical and Experimental Rheumatology 2012
Methotrexate Monotherapy in Juvenile Idiopathic Arthritis Associated Uveitis: Myth or Reality?
No full textObjective: To evaluate the long-term efficacy of methotrexate (MTX) monotherapy in patients with juvenile idiopathic arthritis-associated uveitis (JIA-U). Methods: We analyzed a cohort of patients with JIA-U treated with MTX monotherapy, divided into two groups depending on whether MTX was started before (on-MTX group) or after uveitis diagnosis (MTX-naïve group). The primary endpoint was the time between uveitis inactivity and first relapse. Results: 84 patients entered the study. The median duration of remission on MTX monotherapy resulted 8.2 months. The on-MTX group showed a significant longer time interval between arthritis and uveitis onset and higher need for biologic agents (bDMARD). During follow-up, 40 patients (47.6%) needed bDMARD due to poor control of uveitis. Clinical remission off medication was achieved in 11.9% of patients, all belonging to the MTX-naïve group. Conclusions: MTX monotherapy, although effective in early stages of JIA-U, showed poor disease control in the long term
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
Monoarticular juvenile idiopathic arthritis as a distinct clinical entity A proof-of-concept study
Full text linkBackground: Currently, monoarticular Juvenile Idiopathic Arthritis (monoJIA) is included in the ILAR classification as oligoarticular subtype although various aspects, from clinical practice, suggest it as a separate entity. Objectives: To describe the clinical characteristics of persistent monoJIA. Methods: Patients with oligoJIA and with at least two years follow-up entered the study. Those with monoarticular onset and persistent monoarticular course were compared with those with oligoJIA. Variables considered were: sex, age at onset, presence of benign joint hypermobility (BJH), ANA, uveitis, therapy and outcome. Patients who had not undergone clinical follow-up for more than 12 months were contacted by structured telephone interview. Results: Of 347 patients with oligoJIA, 196 with monoarticular onset entered the study and 118 (60.2%), identified as persistent monoJIA, were compared with 229 oligoJIA. The mean follow-up was 11.4 years. The switch from monoarticular onset to oligoarticular course of 78 patients (38.8%) occurred by the first three years from onset. In comparison with oligoJIA, the most significant features of monoJIA were later age at onset (6.1 vs. 4.7 years), lower female prevalence (70.3 vs. 83.4%), higher frequency of BJH (61.9 vs. 46.3%), lower frequency of uveitis (14.4 vs. 34.1%) and ANA+ (68.6 vs. 89.5%) and better long-term outcome. Conclusions: MonoJIA, defined as persistent arthritis of unknown origin of a single joint for at least three years, seems to be a separate clinical entity from oligoJIA. This evidence may be taken into consideration for its possible inclusion into the new classification criteria for JIA and open new therapeutic perspectives
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
