Abstract
PURPOSE Benign Prostatic Hyperplasia (BPH) is a result of prostate inflammation, frequently occurring in metabolic syndrome (MetS). Low testosterone is common in MetS. A randomized clinical trial was designed to evaluate if 24 weeks of testosterone therapy (TTh) in BPH men with MetS and low testosterone improve urinary symptoms and prostate inflammation. METHODS One-hundred-twenty men with MetS waitlisted for BPH surgery were enrolled. They were categorized into normal testosterone (TT ≥ 12 nmol/L and cFT ≥ 225 pmol/L; n = 48) and testosterone deficient (TD) (TT < 12 nmol/L and/or cFT < 225 pmol/L; n = 72) then randomized to testosterone gel 2% (5 g/daily) or placebo for 24 weeks. At baseline and follow-up, questionnaires for urinary symptoms and trans-rectal ultrasound were performed. Prostate tissue was collected for molecular and histopathological analyses. RESULTS No differences in the improvement of urinary symptoms were found between TTh and placebo (OR [95% CI] 0.96 [0.39; 2.37]). In TD + TTh, increase in prostate but not adenoma volume was observed (2.64 mL [0.07; 5.20] and 1.82 mL [- 0.46; 0.41], respectively). Ultrasound markers of inflammation were improved. In a subset of 61 men, a hyper-expression of several pro-inflammatory genes was found in TD + placebo when compared with normal testosterone. TTh was able to counteract this effect. For 80 men, the inflammatory infiltrate was higher in TD + placebo than in normal testosterone (0.8 points [0.2; 1.4]) and TD + TTh men (0.9 points [0.2; 1.5]). CONCLUSIONS Twenty-four weeks of TTh in TD men with BPH and MetS improves ultrasound, molecular and histological proxies of prostate inflammation. This does not result in symptom improvement.

Abstract
PURPOSE In both preclinical and clinical settings, testosterone treatment (TTh) of hypogonadism has shown beneficial effects on insulin sensitivity and visceral and liver fat accumulation. This prospective, observational study was aimed at assessing the change in markers of fat and liver functioning in obese men scheduled for bariatric surgery. METHODS Hypogonadal patients with consistent symptoms (n = 15) undergoing 27.63 ± 3.64 weeks of TTh were compared to untreated eugonadal (n = 17) or asymptomatic hypogonadal (n = 46) men. A cross-sectional analysis among the different groups was also performed, especially for data derived from liver and fat biopsies. Preadipocytes isolated from adipose tissue biopsies were used to evaluate insulin sensitivity, adipogenic potential and mitochondrial function. NAFLD was evaluated by triglyceride assay and by calculating NAFLD activity score in liver biopsies. RESULTS In TTh-hypogonadal men, histopathological NAFLD activity and steatosis scores, as well as liver triglyceride content were lower than in untreated-hypogonadal men and comparable to eugonadal ones. TTh was also associated with a favorable hepatic expression of lipid handling-related genes. In visceral adipose tissue and preadipocytes, TTh was associated with an increased expression of lipid catabolism and mitochondrial bio-functionality markers. Preadipocytes from TTh men also exhibited a healthier morpho-functional phenotype of mitochondria and higher insulin-sensitivity compared to untreated-hypogonadal ones. CONCLUSIONS The present data suggest that TTh in severely obese, hypogonadal individuals induces metabolically healthier preadipocytes, improving insulin sensitivity, mitochondrial functioning and lipid handling. A potentially protective role for testosterone on the progression of NAFLD, improving hepatic steatosis and reducing intrahepatic triglyceride content, was also envisaged.

Abstract
OBJECTIVES Gastroesophageal reflux can occur during anaesthesia and may lead to esophagitis and occasionally oesophageal stricture formation. The aim of the study is to assess two omeprazole protocols on gastroesophageal reflux incidence and pH in anaesthetised dogs. MATERIALS AND METHODS Fifty-five dogs undergoing elective ovariectomy were randomly assigned to: omeprazole single dose 1 mg/kg orally the evening before anaesthesia (20 dogs), omeprazole two doses 1 mg/kg orally the evening and 3 hours before anaesthesia (15 dogs), and control group that did not receive omeprazole (20 dogs). An oesophageal impedance/pH probe was used to measure gastroesophageal reflux incidence and pH during anaesthesia. RESULTS Gastroesophageal reflux was observed in 55% (11/20) of control dogs, 55% (11/20) of dogs receiving omeprazole once and 47% (7/15) of dogs receiving omeprazole twice. The incidence was not statistically significant different between groups. Gastroesophageal reflux pH (mean ± sd) was higher in dogs receiving omeprazole twice (6.3 ± 1.5), when compared to either control dogs (3.8 ± 1.1) or dogs receiving omeprazole once (4.1 ± 1.5). Strongly acidic reflux (pH < 4) was observed in 7% (1/15) of dogs receiving omeprazole twice versus 55% (11/20) and 35% (7/20) of control dogs and dogs receiving omeprazole once, respectively. CLINICAL SIGNIFICANCE Omeprazole administered the evening and 3 hours before anaesthesia increased gastroesophageal reflux pH and decreased the incidence of strongly acidic reflux in dogs. A single dose of omeprazole given the evening before anaesthesia had no effect on reflux pH.

Abstract
BACKGROUND Scrotal color Doppler ultrasound (CDUS) still suffers from lack of standardization. Hence, the European Academy of Andrology (EAA) has promoted a multicenter study to assess the CDUS characteristics of healthy fertile men (HFM) to obtain normative parameters. OBJECTIVES To report and discuss the scrotal organs CDUS reference ranges and characteristics in HFM and their associations with clinical, seminal, and biochemical parameters. METHODS A cohort of 248 HFM (35.3 ± 5.9years) was studied, evaluating, on the same day, clinical, biochemical, seminal, and scrotal CDUS following Standard Operating Procedures. RESULTS The CDUS reference range and characteristics of the scrotal organs of HFM are reported here. CDUS showed a higher accuracy than physical examination in detecting scrotal abnormalities. Prader orchidometer (PO)- and US-measured testicular volume (TV) were closely related. The US-assessed TV with the ellipsoid formula showed the best correlation with the PO-TV. The mean TV of HFM was ~ 17 ml. The lowest reference limit for right and left testis was 12 and 11 ml, thresholds defining testicular hypotrophy. The highest reference limit for epididymal head, tail, and vas deferens was 12, 6, and 4.5 mm, respectively. Mean TV was associated positively with sperm concentration and total count and negatively with gonadotropins levels and pulse pressure. Subjects with testicular inhomogeneity or calcifications showed lower sperm vitality and concentration, respectively, than the rest of the sample. Sperm normal morphology and progressive motility were positively associated with epididymal head size/vascularization and vas deferens size, respectively. Increased epididymis and vas deferens sizes were associated with MAR test positivity. Decreased epididymal tail homogeneity/vascularization were positively associated with waistline, which was negatively associated with intratesticular vascularization. CDUS varicocele was detected in 37.2% of men and was not associated with seminal or hormonal parameters. Scrotal CDUS parameters were not associated with time to pregnancy, number of children, history of miscarriage. CONCLUSIONS The present findings will help in better understanding male infertility pathophysiology, improving its management.

Abstract
In men, testosterone (T) production declines as a function of ageing. Late-onset hypogonadism (LOH) is the most commonly used term to indicate this age-related condition. In LOH, the relative clinical significance and the potential benefit of testosterone treatment (TTh) are still the subject of strong criticisms in the scientific community. The debate is further complicated by the recent position statement of the US Food and Drug Administration (FDA) emphasizing that, in LOH, the benefits and safety of TTh have not been fully established. Hence, the FDA required a labeling change to inform patients about a possible increased cardiovascular (CV) risk of TTh. Similar considerations were previously released by the FDA and by Health Canada concerning a TTh-related venous thromboembolism (VTE) risk. In this review, we will summarize the available evidence concerning a possible link among TTh and CV and VTE risks. For this purpose, data derived from epidemiological studies analyzing relationships between the aforementioned risks and endogenous T levels will be analyzed. In addition, evidence deriving from interventional studies including pharmacoepidemiological and placebo-controlled randomized controlled trials (RCTs) will be examined. Our analysis shows that available data do not support an increased CV risk related to TTh. Similar considerations can be drawn for the relationship between TTh and VTE. The previously reported cases of TTh-related VTE were frequently related to a previously undiagnosed thrombophilia-hypofibrinolysis status. Hence, an anamnestic screening for thrombophilia before starting TTh is recommended, just as it is for the use of oral contraceptives.

Abstract
STUDY QUESTION Is thyroid hormones (TH) evaluation of clinical value in the work-up of males of infertile couples? STUDY ANSWER Our results suggest that TH evaluation is not mandatory in the work-up of male infertility. WHAT IS KNOWN ALREADY A few previous studies performed on a limited series of subjects reported a negative impact of hyper- and hypo-thyroidism on semen volume, sperm concentration, progressive motility and normal morphology. No previous study has systematically evaluated associations between TH variation, semen parameters and ultrasound characteristics of the male genital tract. STUDY DESIGN, SIZE AND DURATION Cross-sectional analysis of a consecutive series of 172 subjects seeking medical care for couple infertility from September 2010 to November 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS Of the entire cohort, 163 men (age 38.9 ± 8.0 years) free of genetic abnormalities were studied. All subjects underwent a complete andrological and physical examination, biochemical and hormonal assessment, scrotal and transrectal colour-Doppler ultrasound (CDUS) and semen analysis (including seminal interleukin 8 levels, sIL-8) evaluation within the same day. MAIN RESULTS AND THE ROLE OF CHANCE Among the patients studied, 145 (88.9%) showed euthyroidism, 6 (3.7%) subclinical hyper- and 12 (7.4%) subclinical hypo-thyroidism. No subjects showed overt hyper- or hypo-thyroidism. At univariate analysis, no associations among thyroid-stimulating hormone (TSH) or TH levels and sperm parameters were observed. Conversely, we observed positive associations among free triiodothyronine (fT3) and free thyroxine (fT4) levels, ejaculate volume and seminal fructose levels. In a multivariate model, after adjusting for confounders such as age, body mass index, smoking habit, sexual abstinence, calculated free testosterone, prolactin and sIL-8 levels, only the associations found for fT3 levels were confirmed. When CDUS features were investigated, using the same multivariate model, we found positive associations between fT3 levels and seminal vesicles (SV) volume, both before and after ejaculation (adj. r = 0.354 and adj. r = 0.318, both P < 0.0001), as well as with SV emptying (ΔSV volume; adj. r = 0.346, P < 0.0001) and echo-texture inhomogeneity. In addition, after adjusting for confounders, negative associations between fT4 levels and epididymal body and tail diameters were found. No significant associations between TSH or TH levels and CDUS features of other organs of the male genital tract, including testis and prostate, were found. Finally, when the features of subjects with euthyroidism, subclinical hypo- and hyper-thyroidism were compared, no significant differences in seminal or hormonal parameters were found. Conversely, evaluating CDUS parameters, subjects with subclinical hyperthyroidism showed a higher difference between the SV longitudinal diameters measured before and after ejaculation when compared with that of subclinical hypothyroid men, even after adjusting for confounders (P < 0.007). All the other male genital tract CDUS characteristics did not differ among groups. LIMITATIONS, REASONS FOR CAUTION First, the number of patients investigated is relatively small and those with (subclinical) thyroid dysfunctions are an even smaller number; hence, it is therefore difficult to draw firm conclusions. Moreover, the present results are derived from patients consulting an Italian Andrology Clinic for couple infertility, and could have different characteristics from the male general population or from those males consulting general practitioners for reasons other than couple infertility. Finally, due to the cross-sectional nature of the study, neither a causality hypothesis nor mechanistic models can be inferred. WIDER IMPLICATIONS OF THE FINDINGS Although no associations between TH and sperm parameters were observed, present data support a positive effect of TH on SV size and a permissive role on the ejaculatory machinery, likely through an action on SV and epididymal contractility. This is the first study reporting such evidence. However, in contrast with the view that TH assessment is important for female fertility, our results do not support a systematic evaluation of thyroid function in males of infertile couples. How TH abnormalities impact male fertility needs to be addressed by further studies. STUDY FUNDING/COMPETING INTERESTS No funding was received for the study. None of the authors have any conflict of interest to declare.

Abstract
STUDY QUESTION What is the impact of smoking behaviour on seminal, hormonal and male genital tract ultrasound parameters in subjects seeking medical care for couple infertility? STUDY ANSWER In males of infertile couples, current smokers (CS), when compared with non-smokers, show lower ejaculate and ultrasound-derived seminal vesicles (SV) volume, despite higher testosterone levels. WHAT IS KNOWN ALREADY Data on the effects of smoking on male fertility are conflicting. A correlation between smoking and reduced semen parameters has been reported, however, with a high heterogeneity among studies. An association between smoking behaviour and higher testosterone levels in men has been described in several, but not all, the previous studies. No study has systematically evaluated the impact of smoking on the male genital tract ultrasound characteristics. STUDY DESIGN, SIZE AND DURATION Retrospective cross-sectional analysis of a consecutive series of 426 subjects seeking medical care for couple infertility from January 2010 to July 2013. PARTICIPANTS/MATERIALS, SETTING, METHODS From the entire cohort, 394 men (age 36.0 ± 8.0 years) free of genetic abnormalities were selected. All subjects underwent a complete andrological and physical examination, biochemical and hormonal assessment, scrotal and transrectal colour-Doppler ultrasound and semen analysis (including seminal interleukin-8 levels, sIL-8) within the same day. MAIN RESULTS AND THE ROLE OF CHANCE Among the patients evaluated, 229 were never smokers (NS), 56 past smokers (PS) and 109 CS. When CS were compared with the rest of the sample (non-smokers, NS + PS), in a multivariate model (analysis of covariance, ANCOVA) adjusted for age, lifestyle (including alcohol, cannabis and physical activity), BMI and sex hormone-binding globulin, significantly higher androgen (total testosterone, P = 0.001; calculated free testosterone, P < 0.005) and lower FSH (P < 0.05) levels were observed in CS. However, when total testosterone was also included in the multivariate model as a further covariate, the difference in FSH levels was not confirmed. In a similar model, a lower ejaculate volume (P < 0.01) and a higher prevalence of normal sperm morphology (P < 0.02) were also detected in CS in comparison with the rest of the sample. However, when total testosterone was also included in the multivariate model as a further covariate, only the difference in ejaculate volume between CS and non-smokers was confirmed (-0.61 ± 0.23 ml, P < 0.01). Finally, CS showed lower total SV volume, before and after ejaculation, even after adjusting for confounders (P = 0.02 and <0.01, respectively). Similar results were observed when the reported number of cigarettes smoked or the number of pack-years was considered separately. LIMITATIONS, REASONS FOR CAUTION The present results are derived from patients consulting an Andrology Clinic for couple infertility, who could have different characteristics from the general male population or males consulting general practitioners for reasons other than couple infertility. In addition, we did not have a true control group composed of age-matched, apparently healthy, fertile men, and therefore true normative data of sonographic parameters cannot be inferred. Due to the cross-sectional nature of our study, neither a causality hypothesis nor mechanistic models can be drawn. Finally, this is a retrospective study, and further prospective studies are required. WIDER IMPLICATIONS OF THE FINDINGS We report an apparent paradox in CS: lower SV volume despite higher testosterone levels. Our data suggest that smoking may negatively affect SV volume in an independent manner, as the difference between CS and non-smokers retained significance after adjusting for confounders including testosterone. This is the first study reporting such ultrasound evidence. How this new smoking-related alteration, along with low semen volume, impacts male fertility needs to be addressed by further studies. STUDY FUNDING/COMPETING INTERESTS No funding was received for the study. None of the authors have any conflict of interest to declare.

Abstract
BACKGROUND Autoantibodies against thyroid hormones (THAbs) directed towards triiodothyronine (T3-Ab) and/or thyroxine (T4-Ab) are very rare in the general population. They are increased in some nonthyroidal autoimmune diseases, where they seem to predict autoimmune thyroid disorders (ATDs). So far, their presence in patients with vitiligo has not been evaluated, but it might have a possible predictive role. OBJECTIVES To assess the prevalence of THAbs in a group of vitiligo patients and to correlate their presence with clinical and historical parameters. METHODS In total 79 patients with nonsegmental vitiligo and 100 controls were examined. Clinical characteristics of vitiligo and family and personal medical history were evaluated. Antinuclear autoantibodies, thyroid hormones and thyroid autoantibodies were measured. IgM T3-Ab, IgG T3-Ab, IgM T4-Ab and IgG T4-Ab were assayed by a radioimmunoprecipitation technique. Fisher's test, Student's t-test and χ(2)-test were used for statistical analysis. RESULTS Overall 77 of 79 patients (97%) had at least one type of THAb (11 T3-Ab, 10 T4-Ab, 56 both). In the control group, only one person (1%) had THAbs. In patients with vitiligo, T3-Abs were significantly associated with leucotrichia (IgM+IgG, P = 0.033; IgG, P = 0.039; IgM, P = 0.005) and thyroglobulin autoantibodies (IgM+IgG, P = 0.031; IgG, P = 0.058), while the absence of T3-Ab was related to personal history of cancer (IgM+IgG, P = 0.021; IgG, P = 0.039). T4-Abs were significantly associated with vitiligo activity (IgM+IgG, P < 0.001; IgM, P = 0.037) and duration (IgG, P = 0.013). CONCLUSIONS The surprisingly high prevalence of THAb in patients with vitiligo and their associations suggest a possible pathogenetic role in the disease and stress the tight link between vitiligo and ATDs. Further evaluation in a larger group of patients and an adequate follow-up are needed to define their potential predictive role.

Abstract
Oxidative stress (OS) is involved in several human diseases, including obesity, diabetes, atherosclerosis, carcinogenesis, as well as genetic diseases. We previously found that OS occurs in Down Syndrome as well as in Beckwith-Wiedemann Syndrome (BWS). Here we describe the clinical case of a female patient with Prader Willi Syndrome (PWS), a genomic imprinting disorder, characterized by obesity, atherosclerosis and diabetes mellitus type 2, pathologies in which a continuous and important production of free radicals takes place. We verified the presence of OS by measuring a redox biomarkers profile including total hydroperoxides (TH), non protein-bound iron (NPBI), thiols (SH), advanced oxidation protein products (AOPP) and isoprostanes (IPs). Thus we introduced in therapy an antioxidant agent, namely potassium ascorbate with ribose (PAR), in addition to GH therapy and we monitored the redox biomarkers profile for four years. A progressive decrease in OS biomarkers occurred until their normalization. In the meantime a weight loss was observed together with a steady growth in standards for age and sex.

Abstract
BACKGROUND The global obesity epidemic has paralleled a decrease in semen quality. Yet, the association between obesity and sperm parameters remains controversial. The purpose of this report was to update the evidence on the association between BMI and sperm count through a systematic review with meta-analysis. METHODS A systematic review of available literature (with no language restriction) was performed to investigate the impact of BMI on sperm count. Relevant studies published until June 2012 were identified from a Pubmed and EMBASE search. We also included unpublished data (n = 717 men) obtained from the Infertility Center of Bondy, France. Abstracts of relevant articles were examined and studies that could be included in this review were retrieved. Authors of relevant studies for the meta-analysis were contacted by email and asked to provide standardized data. RESULTS A total of 21 studies were included in the meta-analysis, resulting in a sample of 13 077 men from the general population and attending fertility clinics. Data were stratified according to the total sperm count as normozoospermia, oligozoospermia and azoospermia. Standardized weighted mean differences in sperm concentration did not differ significantly across BMI categories. There was a J-shaped relationship between BMI categories and risk of oligozoospermia or azoospermia. Compared with men of normal weight, the odds ratio (95% confidence interval) for oligozoospermia or azoospermia was 1.15 (0.93-1.43) for underweight, 1.11 (1.01-1.21) for overweight, 1.28 (1.06-1.55) for obese and 2.04 (1.59-2.62) for morbidly obese men. CONCLUSIONS Overweight and obesity were associated with an increased prevalence of azoospermia or oligozoospermia. The main limitation of this report is that studied populations varied, with men recruited from both the general population and infertile couples. Whether weight normalization could improve sperm parameters should be evaluated further.

Abstract
We have previously reported that infertile patients with diabetes mellitus (DM) have a particular ultrasound features of the seminal vesicles (SV) characterized by higher fundus-to-body ratio and lower pre- and post-ejaculatory difference in body antero-posterior diameter (APD). Based on these premises the aim of the present study was to investigate possible ultrasound SV changes in infertile patients with DM and diabetic neuropathy (DN), after prolonged administration of tadalafil (TAD) (a specific phosphodiesterase-5 inhibitor). To accomplish this, 20 infertile patients with symptomatic DN and erectile dysfunction were selected and arbitrarily divided into two groups which were assigned to: daily administration of 5 mg TAD for 3 months (Group A) (n = 10) and administration of placebo (Group B) (n = 10). All patients underwent to scrotal and prostate-vesicular transrectal ultrasound evaluation and semen analysis (Laboratory Manual for the Examination and Processing of Human Semen, WHO, 2010) before and after treatment. The following SV US parameters were recorded: (i) body APD; (ii) fundus APD; (iii) parietal thickness of the right and left SVs; and (iv) number of polycyclic areas within both SVs. We then calculated the following parameters: (i) fundus/body (F/B) ratio; (ii) difference of the parietal thickness between the right and the left SV and (iii) pre- and post-ejaculatory APD difference. In addition, we also evaluated the SV ejection fraction. Group A patients showed a significant reduction in F/B ratio and higher pre- and post-ejaculatory body SV APD difference compared with baseline or Group B after 3 months. These patients showed also a significant increase in SV ejection fraction and a significant improvement of the total sperm count, progressive motility, seminal levels of fructose, leucocytes and ejaculate volume. In conclusion, these results suggest that infertile DM patients with DN and erectile dysfunction had an improvement of ultrasound features suggestive of diabetic neuropathy after daily treatment with low doses of TAD.

Abstract
BACKGROUND Although non-segmental vitiligo is commonly considered an autoimmune disease, the possible differences between non-segmental vitiligo patients with and without autoimmune signals have not been clearly established. OBJECTIVE To perform a comparison of non-segmental vitiligo patients with autoimmune signals (AIS) vs. those without autoimmune signals (NAIS) in regards to clinical characteristics and toxic/drug exposure. METHODS 112 vitiligo patients were selected for a sex and age matched (1 : 1) case control study at an university based dermatology outpatient hospital specialized in pigmentary disorders. Medical assessment was performed by dermatologists using the modified Vitiligo European Task Force form and serological and clinical signs of autoimmunity were evaluated. RESULTS Disease duration, age of onset, patient history of cardiovascular disease, past smoking history, use of drugs, and consummation of goitrogenic foods were all significantly increased in the AIS group using McNemar's test for matched pairs. In our conditional regression model, the simultaneous presence of disease duration, use of prescription drugs, and consummation of goitrogenic foods were the best predictors of AIS vitiligo patients. CONCLUSION The evaluation of non-segmental vitiligo patients according to the presence vs. the absence of autoimmune signals allows us to correlate patients exhibiting autoimmune phenomenon with certain clinical characteristics, namely long disease duration, use of prescription drugs, and consumption of goitrogenic substances. In the presence of the aforementioned clinical profile, we suggest an evaluation of autoimmune signals.

Abstract
Cancer stem cell (SC) chemoresistance may be responsible for the poor clinical outcome of non-small-cell lung cancer (NSCLC) patients. In order to identify the molecular events that contribute to NSCLC chemoresistance, we investigated the DNA damage response in SCs derived from NSCLC patients. We found that after exposure to chemotherapeutic drugs NSCLC-SCs undergo cell cycle arrest, thus allowing DNA damage repair and subsequent cell survival. Activation of the DNA damage checkpoint protein kinase (Chk) 1 was the earliest and most significant event detected in NSCLC-SCs treated with chemotherapy, independently of their p53 status. In contrast, a weak Chk1 activation was found in differentiated NSCLC cells, corresponding to an increased sensitivity to chemotherapeutic drugs as compared with their undifferentiated counterparts. The use of Chk1 inhibitors in combination with chemotherapy dramatically reduced NSCLC-SC survival in vitro by inducing premature cell cycle progression and mitotic catastrophe. Consistently, the co-administration of the Chk1 inhibitor AZD7762 and chemotherapy abrogated tumor growth in vivo, whereas chemotherapy alone was scarcely effective. Such increased efficacy in the combined use of Chk1 inhibitors and chemotherapy was associated with a significant reduction of NSCLC-SCs in mouse xenografts. Taken together, these observations support the clinical evaluation of Chk1 inhibitors in combination with chemotherapy for a more effective treatment of NSCLC.

Abstract
BACKGROUND Obesity is associated with a systemic, low-grade inflammatory state. Although the relationship between obesity and semen parameters or prostate diseases has been previously investigated, the association between body mass index (BMI), prostate inflammatory diseases and color- Doppler ultrasound (CDU) of the male genital tract (MGT) has been poorly studied. AIM To evaluate the association between BMI and CDU features of the MGT, signs and symptoms of prostate inflammation, semen parameters. MATERIALS/SUBJECTS AND METHODS We studied 222 men seeking medical care for couple infertility. According to the World Health Organization classification, subjects were divided into 3 groups: normal weight (no.=131, BMI=18.5-24.9 kg/m2), overweight (no.=71, BMI=25.0-29.9 kg/m2), obese (no.=20, BMI≥30.0 kg/m2). All patients underwent simultaneous testosterone evaluation and seminal analysis, including interleukin 8 (sIL-8), along with scrotal and transrectal CDU, before and after ejaculation. Prostatitis symptoms were evaluated by National Institutes of Health- Chronic Prostatitis Symptom Index questionnaire. RESULTS After adjusting for age and testosterone levels, higher BMI was significantly related to higher prostate volume and several CDU features of the prostate, including macro-calcifications, inhomogeneity, higher arterial peak systolic velocity (the latter adjusted also for blood pressure), but not with abnormalities of testis, epididymis, seminal vesicles. Furthermore, higher BMI and BMI class were significantly related to higher sIL-8, a reliable surrogate marker of prostate inflammatory diseases, even after adjustment for age. Conversely, no associations among BMI, clinical symptoms of prostatitis or semen parameters were observed. CONCLUSIONS Subjects with higher BMI might develop CDU and biochemical signs suggestive of prostate inflammation, although not clinically overt.

Abstract
Although it is well established that all the aspects of male reproduction are hormonally regulated, the endocrine control of the ejaculatory reflex is still not completely clarified. Sex steroids, thyroid and pituitary hormones (oxytocin and prolactin) have been proposed to control the ejaculatory process at various levels; however, only a few reports are currently available. The aim of this study was to evaluate the contribution of testosterone, thyrotropin (TSH) and prolactin (PRL) in the pathogenesis of ejaculatory dysfunction in a large series of subjects consulting for sexual dysfunction. Among the 2652 patients studied, 674 (25.2%) and 194 (7.3%) reported premature and delayed ejaculation (PE and DE), respectively. Categorizing ejaculatory difficulties on an eight-point scale starting from severe PE and ending with anejaculation (0 = severe PE, 1 = moderate PE, 2 = mild PE, 3 = no difficulties, 4 = mild DE, 5 = moderate DE, 6 = severe DE and 7 = anejaculation), PRL as well as TSH levels progressively increased from patients with severe PE towards those with anejaculation. Conversely, the opposite was observed for testosterone levels. All of these associations were confirmed after adjustment for age (adjusted r = 0.050, 0.053 and -0.038 for PRL, TSH and testosterone, respectively; all p < 0.05). When all hormonal parameters were introduced in the same regression model, adjusting for age, ΣMHQ (an index of general psychopathology) and use of selective serotonin reuptake inhibitor antidepressants, they were independently associated with ejaculatory problems (adjusted r = 0.056, 0.047 and -0.059 for PRL, TSH and testosterone, respectively; all p < 0.05). This study indicates endocrine system is involved in the control of ejaculatory function and that PRL, TSH and testosterone play an independent role.

Abstract
BACKGROUND Current studies have treated a limited portion of the subjective aspects of vitiligo patients and have yet to elucidate possible psychological differences between those with autoimmune markers (AIM) with respect to those without autoimmune markers (NAIM). OBJECTIVE To perform an age and gender-matched 1:1 case-control study through a comparison of non-segmental vitiligo patients with autoimmune features vs. those without autoimmune features in regards to psychiatric features, psychosomatic aspects and social parameters. METHODS A total of 112 non-segmental vitiligo patients have been examined at the Florence University dermatology outpatient service (2nd dermatology unit). Vitiligo with an autoimmune background was defined by the presence of autoimmune antibodies and/or autoimmune diseases. Psychiatric screening was performed by dermatologists using the modified Middlesex Healthcare Questionnaire (MHQ); psychosomatic aspects and social impact were analysed with a standardized, Florentine questionnaire. RESULTS Upon performing a conditional regression model, age, phobia and obsession were significantly predictive of the presence of AIM and a low total MHQ score was significantly predictive of NAIM in vitiligo patients. With univariate analysis, we found significant differences in: identifiable stress related to the onset of vitiligo, vitiligo triggered by stress, and modified interpersonal relationships related to vitiligo, which were associated with the subgroup containing autoimmunity markers. CONCLUSIONS We found a higher prevalence of age, obsession and phobia among vitiligo patients AIM as compared to vitiligo patients NAIM. Thus, in the presence of demonstrated autoimmunity, screening for particular psychiatric aspects may be useful in the clinical practice of vitiligo.

Abstract
IntroductionMasturbation is a common, but often neglected, male sexual behavior. Objectives and aims: To investigate the psychobiological correlates of self-reported masturbation in the last 3 months.MethodsA consecutive series of 2,786 heterosexual male patients consulting an outpatient clinic for erectile dysfunction (ED) was studied. Several hormonal, biochemical and instrumental parameters were investigated. Patients were interviewed, prior to the beginning of any treatment, with Structured Interview on Erectile Dysfunction (SIEDY) and ANDROTEST structured interviews. They also completed the Middlesex Hospital Questionnaire.ResultsAmong the patients studied, 1,781 (61.9%) reported they had masturbated at least once per month in the preceding 3 months. The frequency of masturbation was inversely related to age (r = -0.329; P < 0.0001) and directly associated with education level (adj r = 0.052, P < 0.05 after adjustment for age). A feeling of guilt during masturbation was reported by 274 (15.4%) patients. After adjusting for age, masturbation was positively associated with testosterone levels, stressful conditions, and both unstable and long-lasting couple relationship. Urogenital problems also increased the chance of masturbation. Reported guiltiness during autoeroticism was associated with psychological disturbances, low prolactin, low testosterone, and increased relational problems.ConclusionsThis study indicates that masturbation is a relatively frequent behavior in male subjects with ED. Inquiring about this sexual behavior is an important issue for understanding overall patients’ sexual attitudes and behavior.

Abstract
ABSTRACTThe main objective of our research is the development of totally non-destructive methodologies for the investigation of art works. We propose the use of fiber optic reflectance spectroscopy (FORS) in the visible and near-infrared region as a tool for the identification of the pigments used in painting. We have considered several representative inorganic artists' pigments (mainly till the Renaissance period); powder X-ray diffractograms and diffuse reflectance spectra in the visible, near-, middle- and far-infrared range were recorded for pure pigments. Then we prepared suitable samples with the same pigments using fresco, tempera and oil techniques. The visible and near-infrared spectra of these samples were recorded using an optical fiber spectrum analyzer; color analysis (chromaticity, dominant wavelength and purity) was also performed. The obtained results were used in the interpretation of the spectra obtained from some paintings collected in the Uffizi Gallery, Florence (Giotto and Luca Signorelli). The pointwise information obtained by FORS analysis was also used to calibrate and tune an image spectroscopy system, based on sequences of band-pass filtered images in the near infrared range.

Abstract
While the association of Klinefelter's Syndrome (KS) with infertility is well-known, very few investigations have evaluated the prevalence of sexual dysfunction in KS. The aim of the present study was to systematically analyse the prevalence of KS in a consecutive series of adult male patients consulting for sexual problems and to investigate its specific correlates. Among a consecutive series of 1386 men (mean age 48.9 +/- 12.7 years old), 23 (1.7%) subjects with KS were found. Patients with KS were younger and more often hypogonadal when compared with the rest of the sample. Among patients with KS, five (22.7%) subjects reported severe erectile dysfunction, 14 (60.9%) hypoactive sexual desire (HSD), two (9.5%) premature and two (9.5%) delayed ejaculation. Only the association between KS and HSD was confirmed after adjustment for age [HR = 3.2 (1.37-7.5)], however, when patients with KS were compared with age, smoking habit, and testosterone matched controls, even the association between KS with HSD disappeared. In comparison to matched hypogonadal controls, subjects with KS had lower levels of education, a higher frequency of cryptorchidism and poorer pubertal progression. In conclusion, our results indicate that sexual dysfunction present in KS is not specifically associated with the syndrome but is caused by the underlying hypogonadal state. Further studies are needed to evaluate the efficacy of testosterone substitution in ameliorating the hypoactive sexual desire often reported in subjects with KS.

Abstract
General dynamic penile color doppler ultrasound (D-PCDU) screening in patients with erectile dysfunction (ED) has been questioned due to an inadequate cost-benefit ratio. The aim of the present study is to evaluate the validity of different risk scores in the identification of patients being screened for arteriogenic ED (AED) at D-PCDU. A consecutive series of 738 patients with ED was studied. AED was defined when peak systolic velocity (PSV) was lower than 25 cm/sec. The assessment of cardiovascular risk was evaluated using different risk engines, derived from the Framingham, the PROCAM and the Progetto Cuore studies. An iterative receiver operator characteristic (ROC) curve analysis was used to determine the most proper threshold for different scales for the screening of AED. Among the patients studied, 52 (7%) had PSV<25 cm/sec. The area under the ROC curves for pathological PSV in relation to cardiovascular risk estimated with different engines was 0.762+/-0.03, 0.716+/-0.03, and 0.667+/-0.03 for Progetto Cuore, Framingham, and PROCAM engines, respectively. Sensitivity and specificity of Progetto Cuore estimated risk were 67%, 71% when a threshold of 15% was chosen. Corresponding figures for Framingham and PROCAM engine were 74%, 57% and 69%, 55%, respectively. If D-PCDU is performed only on patients with cardiovascular risk >15%, who represent about 1/4 of all patients (26.8%), as estimated by Progetto Cuore, about 70% of cases of arteriogenic ED can be identified. Estimated cardiovascular risk, assessed through risk engines, could be used to identify patients who should undergo D-PCDU evaluation for the diagnosis of AED.

Abstract
Lung carcinoma is often incurable and remains the leading cancer killer in both men and women. Recent evidence indicates that tumors contain a small population of cancer stem cells that are responsible for tumor maintenance and spreading. The identification of the tumorigenic population that sustains lung cancer may contribute significantly to the development of effective therapies. Here, we found that the tumorigenic cells in small cell and non-small cell lung cancer are a rare population of undifferentiated cells expressing CD133, an antigen present in the cell membrane of normal and cancer-primitive cells of the hematopoietic, neural, endothelial and epithelial lineages. Lung cancer CD133(+) cells were able to grow indefinitely as tumor spheres in serum-free medium containing epidermal growth factor and basic fibroblast growth factor. The injection of 10(4) lung cancer CD133(+) cells in immunocompromised mice readily generated tumor xenografts phenotypically identical to the original tumor. Upon differentiation, lung cancer CD133(+) cells acquired the specific lineage markers, while loosing the tumorigenic potential together with CD133 expression. Thus, lung cancer contains a rare population of CD133(+) cancer stem-like cells able to self-renew and generates an unlimited progeny of non-tumorigenic cells. Molecular and functional characterization of such a tumorigenic population may provide valuable information to be exploited in the clinical setting.
