Malattie allergiche e sport
La pratica di attività sportiva è considerata in misura sempre maggiore responsabile di alcune sindromi allergiche (asma da esercizio fisico, anafilassi e orticaria da esercizio, alcune dermatiti da contatto); inoltre lo sport è in grado di indurre modificazioni dei parametri immunologici che possono influire sullo stato di salute dell'individuo (in senso "positivo" ma anche in senso "negativo", con una maggiore esposizione, per esempio, alle infezioni delle alte vie respiratorie). In questo capitolo sono largamente trattate tutte le sindromi allergiche indotte da esercizio, dalla patogenesi alla terapia, alla prevenzione, con alcune note sulle normative antidoping e sulle modificazioni dei parametri immunologici indotte dalla pratica di attività sportiva
Parotid mass as an early sign of Kaposi's sarcoma associated with human herpesvirus 8 infection
Kaposi's sarcoma of an intraparotid lymph node is extremely rare in non-immunocompromised human immuno-1 deficiency virus (HIV)-negative patients. We report a case of a left parotid mass as an early sign of Kaposi's sarcoma-associated human herpesvirus 8 (HHV-8) infection in a 57-year-old patient. After subtotal parotidectomy and histopathological diagnosis of lymph node localization of Kaposi's sarcoma, an accurate dermatological investigation revealed a solitary small lesion in the left foot. Chemotherapy with five cycles of vincristine gave a temporary response of the cutaneous lesion. Seven months later, a few small, firm, purplish-red lesions appeared in different areas of the body, but no adjuvant treatment was accepted by the patient since the lesions occasionally disappeared or remained stable in size. At four years follow-up, there has been no recurrence in the parotid region, and the patient is alive with cutaneous disease but in good general health. The problems related to the diagnosis, the management strategy of such a rare condition and the prognosis are also discussed

RBANS: un valido strumento di valutazione cognitiva in soggetti HIV-infetti in cART = RBANS: a valid tool for cognitive assessment of HIV-infected people on cART
Introduction. Combination Antiretroviral Therapy (cART) has dramatically modified prognosis of individuals with HIV infection, and also the HIV-Associated Neurocognitive Disorders (HAND) spectrum, with reduction of the most severe form of HAND, HIV-Associated Dementia (HAD), but with persistence of the milder forms (ANI: Asymptomatic Neurocognitive Impairment; MND: Mild Neurocognitive Disorder). Screening of HAND requires efficient tools. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a tool that is fast and easy to use, and which is able to assess different cognitive domains. Our purpose is to evaluate the utility of RBANS in screening HAND.
Materials and methods. 95 HIV-infected patients (mean age 47.8 +/- 8.0, range 26-74 years; mean duration of infection 17.0 +/- 8.5, range 1-32 years) on cART, run by Internal Medicine, Allergology and Clinical Immunology, University of Cagliari, underwent neuropsychological assessment with MMSE, Clock Test and RBANS.
Results obtained were compared with participants in the RBANS validation study for the Italian population (control group). Results. Mean scores in MMSE and Clock Test were 29.3 +/- 1.3 and 8.5 +/- 1.4, respectively, indicative of normal cognitive abilities. In RBANS evaluation, however, the total index score was significantly lower than the mean of the control group (84.9 +/- 13.6, P < 0.001), as were indices of immediate memory (82.4 +/- 14.1), language (91.2 +/- 10), attention (87.9 +/- 16.1) and delayed memory (87.3 +/- 17.6).
Conclusions. Our results support the utility of RBANS for identification of HAND in HIV-infected people on cART
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
