No full textPURPOSE: To review the literature on vascular malformations and to clarify their diagnosis, clinical presentation, and treatment options. MATERIAL AND METHODS: The authors reviewed the current literature on vascular malformations looking for more innovative and credited diagnostic criteria and treatment protocols. RESULTS: The review is divided in 4 sections (capillary, venous, arteriovenous, and lymphatic malformations). In each section, the clinical presentation, radiologic features, and treatment options for each kind of vascular malformation are described. The experience and results of the authors also are presented. CONCLUSIONS: Vascular malformations are a heterogeneous group of diseases. Each type of malformation has unique features that make it largely different from the others. Only a clear and correct diagnosis can lead to optimal results
Diet, lipids and lipoproteins in patients with peripheral vascular disease
No full textTwo hundred and eight patients (age range: 26-69 yr) had an angiographic diagnosis of atherosclerotic disease (AD); they were age and sex matched with a control inpatient population. Evaluation of living and dietary habits, with the aid of appropriate computerized clinical charts, showed that AD patients had a significantly higher consumption of cigarettes, carbohydrates and alcohol than controls. In particular, 45.5 per cent of the patients vs 12.5 per cent of controls smoked more than 20 cigarettes daily; 28 per cent vs 16 per cent consumed more than 40 grams of sugar per day; and 54.5 per cent vs 21.5 per cent drank more than 500 ml of wine daily; these and other differences were statistically significant. Type IV hyperlipoproteinemia was almost three times as frequent among patients than among controls (46 per cent vs 18 per cent). Triglyceride levels were significantly more elevated in all age groups considered, while cholesterol levels were significantly higher only among patients of the 50-59 yr age group. Thirteen per cent of patients vs 5 per cent of controls had hyperuricemia. The findings of an increased carbohydrate and alcohol consumption, together with hypertriglyceridemia, may explain the higher incidence of PVD in Italy compared to the United States

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
