Lesch-Nyhan syndrome: Observations on a clinical case [La sindrome di Lesch-Nyhan: osservazione di un caso clinico]
No full textEffects of Spa therapy on serum leptin and adiponectin levels in patients with knee osteoarthritis
No full textAdipocytokine, including leptin and adiponectin, may play an important role in the pathophysiology of osteoarthritis (OA). Spa therapy is one of the most commonly used non-pharmacological approaches for OA, but its mechanisms of action are not completely known. The aim of the present study was to assess whether spa therapy modified plasma levels of leptin and adiponectin in thirty patients with knee OA treated with a cycle of a combination of daily locally applied mud-packs and bicarbonate-sulphate mineral bath water. Leptin and adiponectin plasma levels were assessed at baseline and after 2 weeks, upon completion of the spa treatment period. The concentrations of leptin and adiponectin were measured by ELISA. At basal time, plasma leptin levels were significantly correlated with body mass index (BMI) and gender, but no significant correlation was found with patient age, duration of disease, radiographic severity of knee OA, VAS score or Lequesne index. There was no correlation between plasma adiponectin level and BMI, gender and age, duration of the disease, radiographic severity of knee OA and VAS score. A significant correlation of plasma adiponectin levels was found only with the Lequesne index. At the end of the mud-bath therapy cycle, serum leptin levels showed a slight but not significant increase, while a significant decrease (P < 0.05) in serum adiponectin levels was found. However, leptin and adiponectin concentrations after treatment were not correlated with other clinical parameters. In conclusion, our data show that spa therapy can modify plasma levels of the adipocytokines leptin and adiponectin, important mediators of cartilage metabolism. Whether this effect may play a potential role in OA needs further investigation
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
Clinical report of a case of CREST syndrome [Osservazione clinica di un caso di sindrome CREST]
No full textA case of CREST syndrome presenting with marked diffuse calcinosis and prevailing joint involvement is presented by the authors. Diffractometry revealed the presence of calcified hydroxy-apatite crystals within subcutaneous nodules. Scleroderma-like microcirculatory changes with blood flow alterations typical of Raynaud's syndrome were present on capillaroscopy. The authors feel the case to be of interest not only in view of the rare occurrence of the condition but also of the particular extent and severity of the signs and symptoms presented by this patient
Determination of plasma levels of apolipoprotein E and of HDL-cholesterol in gouty patients [Determinazione dei livelli plasmatici delle apolipoproteine E delle HDL-C in pazienti gottosi]
No full textThe authors have examined the levels of the plasma cholesterol and triglycerides, of the plasma lipoprotein (HDL, LDL, VLDL) and of their main apolipoproteins (apo-A and apo-B) in a group of 34 patients affected by gout and in a population of healthy subjects considered as a contrast group, trying to establish a plausible dislipidemic factor which could justify the major occurrence of coronary heart disease in patients suffering from gout. Statistical analysis was done with the t-test. The group of patients affected by gout had significantly higher levels of triglycerides and VLDL-C and lower levels of HDL-C than the population of healthy subjects. The change of the lipoprotein pattern observed in the patients suffering from gout may be linked to reduction of the catabolism of the triglycerides rich lipoprotein. This reduction is probably linked to a inhibition of lipoprotein lipase
Plasma levels of apolipoprotein and HDL-cholesterol in patients with rheumatoid arthritis
No full textThe authors have examined the levels of the plasma cholesterol and triglycerides, of the plasma lipoproteins (HDL, LDL, VLDL) and of their main apolipoproteins (apo-A and apo-B) in a group of 64 patients affected by RA and in a population of healthy subjects considered as a contrast group, trying to establish a plausible dislipidemic factor which could justify the major occurrence of coronary heart disease in those patients suffering from RA. Statistical analysis was done with the T-test. There are not differences in the lipoprotein pattern between the group of patients affected by RA and the population of healthy subjects. The obtained result seem to exclude that such a major occurrence of coronary heart disease in the patients suffering from RA may be linked to the alteration of lipidic metabolism
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
