Determinants of erectile dysfunction risk in a large series of Italian men attending andrology clinics
No full textObjective: To assess determinants of ED in men who asked for a free of charge andrologic consultation during a week focused on andrologic prevention in Italy.
Methods: Men were invited to attend 178 participating andrology centers for a free of charge visit for counselling about urologic or andrologic conditions. Data were recorded with a simple questionnaire used by all centers.
Results: 2499 (19.9%) were diagnosed having ED. The frequency of ED increased with age, ranging from 4.6% in men under 25 years, to 37.6% in men over 74. In comparison with men with primary education the OR of ED was 0.8 (95% CI 0.7-0.9) in men with secondary education and 0.7 (95% CI 0.6-0.9) in those with university degree. After adjusting for age, the risk of ED was significantly higher in men consuming more than 3 glasses/day of alcoholic drinking (OR 1.4, 95% Cl 1.1-2.0), in subjects smoking more than 10 cigarettes/day (OR 1.2, CI 95% 1.1-1.4) and in former smokers (OR 1.2, CI 95% 1.1-1.4). Men performing at least two hours per week of physical activity had a decreased risk of ED (OR 0.8, CI 95% 0.7-0.9). We found an increased risk of ED in men with diabetes (OR 1.2, 95% CI 1.1-1.4), hypertension (OR 1.3, 95% CI 1.1-1.4), cardiopathy (OR 1.5, 95% CI 1.3-1.8) and hypercholesterolemia (OR 1.4, 95% CI 1.2-1.6).
Conclusions: This study provides further data on determinants of ED risk in a large data set and underlines the relationship between ED and cardiovascular diseases
Premature ejaculation: prevalence and associated conditions in a sample of 12,558 men attending the andrology prevention week 2001 : a study of the Italian Society of Andrology (SIA)
No full textIntroduction. Premature ejaculation (PE) is the most frequent sexual complaint.
Aim. To investigate prevalence of PE and its associated conditions.
Methods. We analyzed information gathered from men attending a free andrologic consultation in 186 Italian medical centers, in the setting of a project focused on andrologic prevention.
Main Outcome Measure. Risk factors for PE.
Results. Five hundred sixty-nine men suffered from lifelong PE; 1,855 had previously normal ejaculation; and 2 34 had PE not specified. Men with PE were younger than those without, but after adjusting for concomitant erectile dysfunction the risk of PE significantly decreased with aging. Men more educated, or who had, experienced a divorce had a slightly increased risk. Also, lifestyle and occupational status affected the risk of PE. Concerning medical history, a decreased risk of PE emerged in men with treated diabetes, and no association was found with hypertension, cardiopathy hypercholesterolemia, and peripheral or central neuropathy.
Conclusions. The results of the analysis of a large dataset show that subjects with PE who are seeking treatment either have experienced stress-related problems or have a physical condition predisposing to this dysfunction (genital anomalies, prostate inflammation)
Relationship between pain sensitivity, cardiovascular reactivity to cold pressor test and indexes of activity of the adrenergic and opioid system
No full textAn association between increased blood pressure levels and hypoalgesia has been reported in the experimental animal and in man. The relation between pain perception and cardiovascular function is however still obscure. In order to gain some insight into this aspect, normotensive subjects with low and high tolerance to pain, as assessed by tooth pulp stimulation, were compared for blood pressure and heart rate during cold pressor test, 24 hr urinary catecholamines, supine and upright PRA and plasma beta-endorphin levels. No significant difference was observed between the two groups for casual blood pressure, heart rate and PRA. Compared to subjects with low tolerance to pain, those with high tolerance to pain were significantly older and had: 1) significantly higher levels of diastolic blood pressure and of beta endorphin levels during cold pressor test; 2) significantly higher beta-endorphin levels after cold pressor test; 3) a significantly higher excretion of noradrenaline (but not of adrenaline and dopamine)
Smoking as a risk factor for erectile dysfunction: Data from the Andrology Prevention Weeks 2001-2002 a study of the Italian Society of Andrology (SIA)
No full textObjective: To analyse the relationship between smoking and erectile dysfunction (ED). Methods: To provide further data on this issue, we analysed information gathered from men attending a free andrologic consultation in 234 Italian medical centres, in the setting of a project focused on andrologic prevention. Men were asked about "their ability to achieve and maintain an erection sufficient for satisfactory sexual performance". If they were dissatisfied, they were defined as having ED. Results: Out of 16724 subjects, ED was diagnosed in 4081 men (24.4%). After adjustment for age, marital status, education, alcohol consumption, physical activity and concomitant pathologies, in comparison with never smokers, men who currently smoked more than 10 cigarettes/day and former smokers showed significantly higher odds ratio (ORs 1.4 and 1.3, respectively) for ED. These results were confirmed performing analysis in strata of diabetes, hypertension, cardiovascular disease and hypercolesterolemia. Comments: This transversal observational study shows that the risk of ED is influenced by smoking. A dose- and duration-response effect is present; changes in smoking habits do not seem to significantly affect the risk to develop ED. (c) 2005 Elsevier B.V. All rights reserved
Disfunzioni Sessuali e Parafilie
No full textSi definiscono disfunzioni sessuali le anomalie del desiderio sessuale e delle modificazioni psicofisiologiche che caratterizzano le varie fasi del ciclo di risposta sessuale e che siano di intensità tale da causare notevole disagio e difficoltà interpersonali. Si suddividono in Disturbi del desiderio, dell’eccitazione, dell’orgasmo, da dolore sessuale, dovuti a condizione medica generale, indotte da sostanze e non altrimenti specificate (DSM-IV-TR). Possono inoltre essere distinti a seconda delle condizioni in cui si manifestano: l’insorgenza (permanenti/acquisiti), il contesto (generalizzate/situazionali) e l’etiologia (dovute a fattori psicologici, fattori organici o a fattori combinati). Le parafilie comprendono disturbi della sessualità caratterizzati da ricorrenti e intensi impulsi sessuali, fantasie o comportamenti che coinvolgono oggetti inanimati o partner non consenzienti (inclusi i bambini), o che implicano sofferenza ed umiliazione per sé o per il partner. La diagnosi di parafilia prevede che la loro durata sia superiore ai sei mesi e che causino un significativo disagio a livello sociale, occupazionale o in altre aree importanti del funzionamento dell’individuo

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
