No full textDuplex ultrasound as a reliable alternative to CTangiography for treatment planning of peripheral artery disease
No full textBackground: The aim of this work was to compare the diagnostic accuracy of Duplex ultrasound (DUS) and CT angiography (CTA) in the study of arterial vessels, in patients with chronic peripheral arterial disease (PAD) of the lower limbs to undergo endovascular revascularization with the use of intraprocedural digital angiography (DSA). Methods: Ninety-four patients with obstructive pathology of the arterial axes of the lower limbs were enrolled in the study. In all patients, endovascular revascularization treatment was considered the most suitable therapeutic choice. For this reason, ultrasound and CTA was performed preoperatively in all and based on the data obtained it was decided to classify the arterial tree into five segments: iliac, common femoral, superficial femoral, popliteal and infra-geniculate. According to the degree of stenosis or occlusion, the arteries were scored in no stenotic, stenotic and occluded. The comparison of the data provided by the DUS and the CTA was carried out with reference to the parameters obtained by the DSA. Results: The results of our experience have shown that in the iliac arterial district DUS proved to be less accurate than CT angiography when compared to DSA (Cohen's lc agreement of 0.91 and 1.0, respectively). Good diagnostic concordance was found in the femoro-popliteal district (Cohen's lc agreement 33 between 0.96 and 0.93). On the contrary, when the data of the infra-geniculate area were compared, CT angiography showed a net deficiency compared to DSA and DUS (Cohen's lc: 0.75). Conclusions: Due to its accuracy, high-quality DUS performed by well-trained operators may therefore represent a good alternative to CTA in patients undergoing endovascular revascularization, in order to reduce the use of contrast-enhanced radiological imaging especially when a condition of intolerance to the contrast medium and/or renal insufficiency coexists.

The Impact of SARS-CoV-2 Outbreak on Primary Sjögren's Syndrome: An Italian Experience
No full textObjective: Since no data is available about the personal experience of people with primary Sjögren's syndrome (pSS) with regard to disease burden and management during the novel Severe Acute Respiratory Syndrome coronavirus (SARS-CoV)-2 outbreak, we aimed to explore these aspects with the ultimate goal to identify unmet needs and priorities. Methods: A telephone consultation was scheduled with patients with pSS and information regarding the disease status, ongoing treatment and symptoms/diagnosis of coronavirus disease 2019 (COVID-19) were collected. Clinical records were retrospectively evaluated to gather pre-COVID-19 information. Results: One hundred and two patients with pSS were contacted. Most rheumatology consultations and other pSS-related tests were canceled during the SARS-CoV-2 outbreak. Less than 30% of patients contacted the rheumatologist via telemedicine despite experiencing disease flares or therapy shortage. Disease activity and patient reported symptoms significantly worsened during the closure period. All patients practiced social distancing, most of those employed switched to smart working and different work settings impacted on the type of symptom worsening. Conclusion: This is the first study addressing the personal experience of pSS patients resulting from the impact of the SARS-CoV2 outbreak and it identifies unmet needs and priorities requiring to be addressed. Our findings may help designing individualized strategie

No full textGoing 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
Histopathology of salivary glands
Full text linkSalivary gland (SG) biopsy is a technique broadly applied for the diagnosis of primary Sjögren’s syndrome (pSS), lymphoma accompanying SS, sarcoidosis, amyloidosis, and IgG4-related disease The most peculiar feature of pSS on biopsy is focal lymphocytic sialadenitis. In the past, several histological scores have been reported in the literature to describe glandular involvement during pSS. However, the variability among centres in reporting glandular scores is one of the rationales behind the development of standardised consensus guidance. SGs as well as lacrimal glands are involved in up to 50% of patients with IgG4-related disease with 3 histopathological hallmarks such as dense lymphoplasmacytic infiltration, storiform fibrosis and obliterative phlebitis. SGs can be also affected by amyloidosis with MSG biopsy being more sensitive than that of rectal mucosa or subcutaneous fat. SG involvement is a rare manifestation during sarcoidosis, and the presence of non-caseating granulomas needs to be differentiated from granulomas of other etiology. This review article provides an overview of normal and pathological SGs in the context of rheumatic diseases, identifying key elements in the tissue as diagnostic and prognostic biomarkers, useful in the current clinical practice
