Abstract
PURPOSE Testosterone replacement therapy (TRT) is recommended for the treatment of most cases of male hypogonadism. Transdermal testosterone (T) gels are commonly used in clinical practice; however, there is little evidence concerning how to monitor dosage to bring and maintain serum T levels in the normal physiologic range. METHODS We examined 30 hypogonadal patients undergoing treatment with 40 mg/day transdermal 2% testosterone gel. After a week from treatment onset, all patients underwent a total of four measurements to assess serum total T, bioavailable T and free T at + 2 h (samples A and A') and + 23 h (samples B and B'). RESULTS No significant difference was found concerning total, free and bioavailable T between the two samples taken at the same time points (A vs A' and B vs B'). A repeated-measures mixed effects regression model showed significantly lower serum levels of total, free and bioavailable T at + 23 h compared to + 2 h (total T, β = - 3.050 ± 0.704, p < 0.001; free T, β = - 85.187 ± 22.746, p < 0.001; bioavailable T, β = - 1.519 ± 0.497, p = 0.003) without a significant between-sample variability. Serum T > 3.5 ng/ml at + 2 h was reached in 21/30 patients (70%), but only 11 (36.7%) still had adequate serum T at + 23 h. CONCLUSION Assessment of TRT with transdermal gels at its peak and at its minimum could be useful in providing a finely tailored treatment for hypogonadal men, both preventing supra-physiological levels and maintaining adequate concentrations through the day.

Abstract
PURPOSE Evaluation of the phenotype of primary hyperparathyroidism (PHPT), adherence to International Guidelines for parathyroidectomy (PTx), and rate of surgical cure. METHOD From January 2014-January 2016, we performed a prospective, multicenter study in patients with newly diagnosed PHPT. Biochemical and instrumental data were collected at baseline and during 1-year follow-up. RESULTS Over the first year we enrolled 604 patients (age 61 ± 14 years), mostly women (83%), referred for further evaluation and treatment advice. Five hundred sixty-six patients had sporadic PHPT (93.7%, age 63 ± 13 years), the remaining 38 (6.3%, age 41 ± 17 years) had familial PHPT. The majority of patients (59%) were asymptomatic. Surgery was advised in 281 (46.5%). Follow-up data were available in 345 patients. Eighty-seven of 158 (55.1%) symptomatic patients underwent PTx. Sixty-five (53.7%) of 121 asymptomatic patients with at least one criterion for surgery underwent PTx and 56 (46.3%) were followed without surgery. Negative parathyroid imaging studies predicted a conservative approach [symptomatic PHPT: OR 18.0 (95% CI 4.2-81.0) P < 0.001; asymptomatic PHPT: OR 10.8, (95% CI 3.1-37.15) P < 0.001). PTx was also performed in 16 of 66 (25.7%) asymptomatic patients without surgical criteria. Young age, serum calcium concentration, 24 h urinary calcium, positive parathyroid imaging (either ultrasound or MIBI scan positive in 75% vs. 16.7%, P = 0.001) were predictors of parathyroid surgery. Almost all (94%) of patients were cured by PTx. CONCLUSIONS Italian endocrinologists do not follow guidelines for the management of PHPT. Negative parathyroid imaging studies are strong predictors of a non-surgical approach. PTx is successful in almost all patients.

Abstract
Gender- and sex- related differences represent a new frontier towards patient-tailored medicine, taking into account that theoretically every medical specialty can be influenced by both of them. Sex hormones define the differences between males and females, and the different endocrine environment promoted by estrogens, progesterone, testosterone, and their precursors might influence both human physiology and pathophysiology. With the term Gender we refer, instead, to behaviors, roles, expectations, and activities carried out by the individual in society. In other words, "gender" refers to a sociocultural sphere of the individual, whereas "sex" only defines the biological sex. In the last decade, increasing attention has been paid to understand the influence that gender can have on both the human physiology and pathogenesis of diseases. Even the clinical response to therapy may be influenced by sex hormones and gender, but further research is needed to investigate and clarify how they can affect the human pathophysiology. The path to a tailored medicine in which every patient is able to receive early diagnosis, risk assessments, and optimal treatments cannot exclude the importance of gender. In this review, we have focused our attention on the involvement of sex hormones and gender on different endocrine diseases.

Abstract
PURPOSE The use of recombinant human growth hormone (rhGH) is a common habit among athletes. While the effects of rhGH administration have been described with contrasting results in males, no data exist in females to date. The aim of the present study was to evaluate the effects of rhGH administration on TSH, FT4 and FT3 levels and the time requested to return to baseline values after treatment withdrawal. METHODS Twenty-one healthy trained male and female athletes were treated with 0.03 mg rhGH/kg body mass 6 days/week for 3 weeks. We collected blood samples immediately before the first daily rhGH administration, at 3, 4, 8, 15 and 21 days of treatment and at 3 and 9 days after rhGH withdrawal. RESULTS In males, rhGH administration induced a significant (p < 0.01) early and stable TSH decrease and IGF-I increase, and a delayed FT4 reduction without FT3 modification, suggesting a central regulatory mechanism. In females, rhGH administration induced a significant (p < 0.01) early and transient TSH decrease and IGF-I increase, and a transient reduction in FT4 without any changes in FT3 concentrations. rhGH withdrawal was associated with a prompt normalization of TSH and FT4 levels in males, while in females the effects of rhGH treatment had already disappeared during the last period of treatment. CONCLUSION We suggest that rhGH inhibits TSH at central level both in males and females. The pattern of normalization was different in the two genders probably due to gonadal steroids modulation on GH-IGF-I axis.

Abstract
BACKGROUND The research presented in this paper analyses the clinic-pathological manifestations and work-related health risks identified among outpatients treated in the hospitals of Rome and Buenos Aires. MATERIALS AND METHODS The occupational anamnestic data were collected between 2013 and 2014 through questionnaires with specific items aimed at detecting occupational diseases classified by target organ systems in outpatient clinics of cardiology, dermatology, physical medicine, ophthalmology, orthopedics, endocrinology (thyroid and gonads). An inferential statistical analysis was then carried out to evaluate the relationship between nationality, exposure to occupational risks and the prevalence and incidence of the selected pathologies. An univariate statistical analysis was performed for this purpose and, in the case of statistically significant results, a subsequent multivariate analysis was used to evaluate the incidence of occupational risk factors and nationality on the pathology diagnosed in conjunction with other confounding factors such as smoking habits and gender. The total sample consisted of 1090 subjects of both sexes. Risks were grouped into seven categories and diseases into 12 diagnostic groups. We analyzed the correlation between risks and diseases with respect to hospital outpatients and to the total sample then comparing Argentina and Italy's data. RESULTS Analysis of data revealed a higher prevalence of hypertension and dysmetabolic disorders for DSE (Display Screen Equipment) workers both in Italy and Argentina; however, multivariate analysis showed that smoking represents a confounding factor for this association. A higher prevalence of allergic contact dermatitis (ACD) was found in the population samples of Rome and there appeared to be a correlation between eye disorders/defects and Argentine data source. CONCLUSIONS Our study suggests the usefulness of collecting occupational anamnestic data from outpatient departments to highlight possible associations between occupational risks, lifestyles and pathologies, so as to implement the appropriate prevention strategies.

Abstract
PURPOSE Testosterone (T) exerts different effects on the cardiovascular system. Despite this knowledge, the acute vascular effect of androgen remains still poorly understood. METHODS We investigated the acute effects of T on vascular function in ten men (18-40 years age) with hypogonadism and severe hypotestosteronemia [serum total testosterone (TT) = 0.6 ± 0.3 ng/mL]. In a 4-day double-blind, randomized, placebo-controlled crossover study, we administered 80 mg daily dose of transdermal-T gel (TG) and evaluated endothelial variations with Endopat2000 (reactive hyperemia index, RHI and the augmentation index, AI); also, CAG repeat polymorphism in exon 1 of the androgen receptor gene was investigated. RESULTS After TG administration, RHI significantly improved at 4 h (p < 0.05), while AI improvement was recorded at 4 and 96 h, also when adjusted for heart rate (AI@75; p < 0.01 and p < 0.001, respectively). Direct relationships between ΔT, ΔDHT and ΔRHI variations (r = 0.37, p < 0.01; r = 0.17, p < 0.05, respectively) as well as between "CAG repeats" length and ΔLnRHI at 96 h (p < 0.03, r (2) = 0.47) were found. An inverse relationship between ΔT and ΔAI (p < 0.01, r = -0.35) and ΔAI@75 (p < 0.01, r = -0.38) were found. CONCLUSION Administration of TG causes an acute vasodilation and improves arterial stiffness probably due to non-genomic actions of T. Endothelial vasodilatory response was more pronounced depending on higher plasma TT and DHT levels attained. Clinical implications in elderly frail populations are discussed.

Abstract
BRAF(V600E) is the most frequent genetic mutation in papillary thyroid cancer (PTC) and has been reported as an independent predictor of poor prognosis of these patients. Current guidelines do not recommend the use of BRAF(V600E) mutational analysis on cytologic specimens from fine needle aspiration due to several reasons. Recently, immunohistochemistry using VE1, a mouse anti-human BRAF(V600E) antibody, has been reported as a highly reliable technique in detecting BRAF-mutated thyroid and nonthyroid cancers. The aim of this study was to test the reliability of VE1 immunohistochemistry on microhistologic samples from core needle biopsy (CNB) in identifying BRAF-mutated PTC. A series of 30 nodules (size ranging from 7 to 22 mm) from 30 patients who underwent surgery following CNB were included in the study. All these lesions had had inconclusive cytology. In all cases, both VE1 and BRAF(V600E) genotypes were evaluated. After surgery, final histology demonstrated 21 cancers and 9 benign lesions. CNB correctly diagnosed 20/20 PTC and 5/5 adenomatous nodules. One follicular thyroid cancer and 4 benign lesions were assessed at CNB as uncertain follicular neoplasm. VE1 immunohistochemistry revealed 8 mutated PTC and 22 negative cases. A 100% agreement was found when positive and negative VE1 results were compared with BRAF mutational status. These data are the first demonstration that VE1 immunohistochemistry performed on thyroid CNB samples perfectly matches with genetic analysis of BRAF status. Thus, VE1 antibody can be used on thyroid microhistologic specimens to detect BRAF(V600E)-mutated PTC before surgery.

Abstract
BACKGROUND The present study aims to assess qualitative and quantitative characteristics of tear film and corneal related impairment and to evaluate the quality of life in a cohort of non-exophthalmic Graves' disease (GD) patients. METHODS The series comprised 50 eyes from 25 newly diagnosed GD patients with no proptosis. As control group, 56 eyes of 28 thyroid disease-free subjects were enrolled. RESULTS The results of Schirmer I and II, break-up time, and Oxford scheme showed a significant difference between GD and controls. By ocular surface disease index (OSDI) questionnaire, eleven (44%) GD patients had normal ocular surface, while two (8%) had mild, four (16%) had moderate, and eight (32%) had severe dry eye. The mean score of the OSDI in the GD group was significantly (p < 0.001) higher with respect to the control group. CONCLUSIONS This study shows that the tear film and cornea are damaged in newly non-exophthalmic GD subjects.

Abstract
BACKGROUND Few and conflicting data on the acute adaptive role of the hypothalamic-pituitary-testicular (HPT) axis to sub-maximal endurance exercise exist. AIMS To investigate the acute HPT axis responses to standardized endurance exercises in a laboratory setting and the correlations between testosterone and classic adaptive hormones variations. SUBJECTS AND METHODS 12 healthy male volunteers were recruited for this experimental study. Serum PRL, GH, ACTH, LH, cortisol, DHEAS, testosterone [total (TT), calculated free (cFT) and bioavailable (cBioT)], SHBG, and respective ratios, were evaluated before and after a 30-min sub-maximal exercise on cycle ergometer at individual anaerobic threshold (IAT) and a maximal exercise until exhaustion. Blood samples were collected before exercise (30, 15 min and immediately before), immediately after and at different time points during recovery (+15, +30 and +60 min) for hormones assays. Oxygen consumption and lactate concentration were evaluated. RESULTS Testosterone (TT, cFT and cBioT) acutely increased in all volunteers after both exercises. Testosterone increased in parallel to GH after both exercises and to cortisol only after maximal exercise. Differently from other increased hormones, testosterone increases were not correlated to exercise-intensity-related variables. The anabolic/catabolic steroids ratios were higher after sub-maximal exercise, compared to maximal. CONCLUSIONS A 30-min sub-maximal endurance exercise acutely increased serum testosterone similarly to maximal exercise, but without cortisol increases. Exercise-related testosterone peaks should be considered adaptive phenomena, but few data on their short- and long-term effects exist. Investigations on the mechanisms of adaptation to exercise in active individuals with physiological or pathological hypo-testosteronemia are warranted.

Abstract
Thyroglobulin (Tg) is a key marker in the follow-up of differentiated thyroid cancer (DTC). Diagnostic accuracy of serum Tg is higher after TSH stimulation than during thyroxine treatment. However, some studies suggest that TSH stimulation could be not necessary in a large part of patients, if Tg is measured by high sensitive assay under replacement therapy. The aim of this study was to evaluate the need of Tg stimulation test in DTC followed-up by sensitive Tg assay. In a prospective multicenter explorative study, 68 low or high risk patients underwent Tg measurement on thyroxine (ON-LT4-Tg) and after LT4 withdrawal (OFF-LT4-Tg). Undetectable ON-LT4-Tg and OFF-LT4-Tg values (i. e.,<0.15 ng/ml) were found in 56/68 patients, all with negative imaging workup. Twelve subjects had skewed OFF-LT4-Tg: 8 cases had increased ON-LT4-Tg and local recurrence (n=6), distant metastasis (n=1), or benign thyroglossal duct (n=1); the remaining 4 patients had undetectable ON-T4-Tg but detectable OFF-LT4-Tg and neck metastasis was recorded in one of these. By ROC analysis, the most accurate cutoff for ON-LT4-Tg and OFF-LT4-Tg were set at 0.23 ng/ml and 0.70 ng/ml, respectively. A positive ON-LT4-Tg value accurately predicts a positive stimulation test and confers an Odds Ratio of 464 (95% CI from 26.3 to 8 173.2, p<0.0001) to have persistent/recurrent disease. This study shows that DTC patients with ON-LT4-Tg below 0.23 ng/ml by our high sensitive assay should be considered disease free and they can avoid Tg stimulation test. High sensitive Tg assays should be used to better manage DTC patients.

Abstract
The accuracy of fine needle aspiration cytology (FNAC) is low in medullary thyroid carcinomas (MTC). Recently, a few papers analyzed the measurement of calcitonin (Ct) in washout of the needle after aspiration (WO-Ct) suggesting that this approach may be useful in patients with high serum Ct. Here we reported, for the first time in our best knowledge, 3 patients with multinodular goiter, moderately elevated serum Ct, high value of WO-Ct, and medullary outcome. These findings suggest that in presence of high serum Ct, FNAC should be performed in all nodules, and it should be combined with WO-Ct in all cases.

Abstract
Few papers have shown that a hypoechoic appearance of the thyroid gland at ultrasonography (US) is related to a hypofunction and serum positivity of thyroid antibodies (T-Ab). However, it is not ascertained if normal thyroid appearance at US correspond to normal thyroid laboratory tests. The aim of this study was to assess the value of normal thyroid at US in predicting normal thyroid hormones and negative T-Ab in a cohort of 48 adult patients. All patients (37 females and 11 males) were referred to our hospital to undergo their first thyroid US examination, followed by a thyroid function evaluation. All subjects had normal thyroid gland at US. As a control group 65 patients with hypoechoic and inhomogeneous thyroid gland were enrolled. All 48 patients had normal free-T (3) and free-T (4) levels. While 41 patients (85.4%) showed normal TSH, in 7 subjects (14.6%) TSH was elevated and a significant (p < 0.001) difference was recorded between the two groups in mean TSH value. Positive T-Ab value was found in 5 patients (10.4%) and the remaining 43 patients (89.6%) had negative T-Ab. TSH was not significantly correlated with age, thyroid volume or BMI. The multivariate model showed that only BMI was significantly correlated to thyroid volume (p < 0.01, r(2)=0.31). These results showed that normal thyroid recorded by US matches with normal thyroid laboratory assessment to a large degree. These preliminary data need to be confirmed in a prospective study and in a larger series and should suggest the evaluation of thyrotropin and thyroid antibodies in subjects with normal thyroid gland as assessed by US.

Abstract
BACKGROUND Subclinical hyperthyroidism (sHT) affects cardiovascular (CV) morphology and function; whether such changes can impact on sport eligibility is unclear. AIM This exploratory study evaluated the CV system and sport eligibility in athletes with levothyroxine-induced sHT, in the setting of mandatory pre-participation screening. SUBJECTS AND METHODS A full, non-invasive CV screening (history and physical examination, 12-lead ECG, echocardiography, 24-hour Holter ECG, exercise stress test) was performed in two groups of untrained female athletes affected by non-toxic multinodular goiter. One group was taking levothyroxine at mildly suppressive doses (TG) whereas the other was untreated (UG). There was also a group of healthy controls (HC). RESULTS In TG the following characteristics were observed: a) a higher resting heart rate (HR; p<0.01 and p<0.05, vs HC and UG respectively), b) a thicker left ventricular posterior wall (p<0.05 vs HC, and p<0.05 vs HC and UG, respectively), c) a higher mean HR during the 24-hour Holter ECG (p<0.01 and p<0.05, vs HC and UG respectively), and d) a lower achieved maximum work load (p<0.05, vs HC). No differences in the prevalence of cardiac arrhythmias among groups were observed. Sport eligibility was granted to all except one subject in the TG. CONCLUSIONS Although some alterations were found in athletes with levothyroxine-induced mild sHT, these are probably of limited clinical relevance and they did not contraindicate sport participation in the majority of cases. Future research to address both health risks and the need for specific evaluations (e.g. free thyroxine, TSH, echocardiography) during the preparticipation screening of athletes with sHT is warranted.

Abstract
OBJECTIVE To describe serum and urinary hormones, androgens metabolites and testosterone/epitestosterone ratio profiles after testosterone administration in male hypogonadal volunteers, and to evaluate their possible usefulness in detecting doping with testosterone in treated hypogonadal athletes. DESIGN Controlled open label design vs placebo; pharmacokinetic study. PARTICIPANTS Ten male volunteers affected by severe hypogonadism (serum testosterone <2.31 ng/ml). INTERVENTIONS AND MAIN OUTCOME MEASURES Serum and urinary parameters were evaluated, by radioimmunoassay and gas chromatography-mass spectrometry, before and at different time points for 7/3 weeks after a single administration of testosterone enanthate (250 mg) or placebo, respectively. RESULTS As partially known, testosterone administration increased, with great individual variability, urinary concentrations of glucuronide testosterone, androsterone, etiocholanolone, 5alpha-androstane- 3alpha,17beta-diol, 5beta-androstane-3alpha,17beta-diol, testosterone/ epitestosterone and testosterone/LH ratios; and decreased epitestosterone and 5alpha-androstane-3beta,17beta-diol/5beta-androstane- 3alpha,17beta-diol ratio. Serum testosterone and dihydrotestosterone increased in all volunteers, and concentrations higher than the upper reference limits were observed in many volunteers until 2 weeks after testosterone administration. CONCLUSION Whereas the observed prolonged hyperandrogenism partially limited data interpretation, the report ed characteristics of variation of urinary parameters might be used to suspect testosterone misuse in hypogonadal athletes treated with testosterone enanthate. In this sense, while the actual threshold for tes tos terone/epites tos ter one ratio was confirmed to be of reduced usefulness, we suggest a contemporary evaluation of whole urinary androgen metabolites profile and serum androgens, at specific time points after testosterone enanthate administration. Moreover, an adequate tailoring of treatment, to avoid transitory hyperandrogenism, is highly advisable. Further studies on strategies for detecting doping with testosterone in hypogonadal athletes are warranted.

Abstract
AIM Insomnia is a major problem which decreases life quality. Many causes are involved with it and anxiety is often associated. The underlying mechanism is not completely understood, even though different factors seem to be associated. Among them melatonin and its circadian rhythm is thought to have an important role. In addition, acupressure and acupuncture are known to ameliorate insomnia and anxiety, when a specific wrist point is stimulated (HT 7 Shenmen). With these bases, the aim of the present study has been to evaluate the efficacy of an acupressure device, ''H7-insomnia control'', positioned on HT 7 points, during the night, in terms of general health and anxiety levels, together with the evaluation of sleep quality and the urinary melatonin metabolite 6-hydroxymelatonin sulphate determination, in a number of insomniacs. METHODS Forty patients with insomnia were divided into two groups and randomly received either the H7 or placebo treatments, in a double-blind protocol, for 20 nights. Before and after treatments every subject answered a series of questionnaires (General Health Questionnaire 28 items; State-Trait Anxiety Inventory; Pittsburgh Sleep Quality Index) and collected 24 h urines, divided into two samples of 12 h each. Urinary melatonin metabolite was then determined using a RIA method. RESULTS Data obtained indicate that the device H7-insomnia control is efficacious to ameliorate quality of sleep and reduce anxiety levels in insomniacs, at a higher extent than in the placebo group. In addition, the 24 hours urinary melatonin metabolite rhythm, obtained at the end of treatment, was considered as being normal in a higher percentage of H7-treated patients, with respect to the placebo group. CONCLUSION It is plausible to hypothesize that the wrist acupressure device might be considered a valid tool, without adverse effects since it does not contain pharmaceutical products, that is able to naturally ameliorate sleep quality in insomniacs, acting through a not jet completely clarified mechanism, that may involve melatonin.

Abstract
Whereas experimental studies showed that in healthy trained subjects, the phosphodiesterase-5 inhibitor (PDE-5i) sildenafil improves exercise capacity in hypoxia and not in normoxia, no studies on the effects of the long half-life PDE-5i tadalafil exist. In order to evaluate whether tadalafil influences functional parameters and performance during a maximal exercise test in normoxia, we studied 14 healthy male athletes in a double-blind cross-over protocol. Each athlete performed two tests on a cycle ergometer, both after placebo or tadalafil (at therapeutic dose: 20 mg) administration. Oxygen consumption (VO2), blood lactate, respiratory exchange ratio, rate of perceived exertion, arterial blood pressure (BP), heart frequency (HR) and oxygen pulse (VO2/HR) were evaluated before exercise, at individual ventilatory and anaerobic thresholds (IVT and IAT), at VO2max and during recovery. Compared to placebo, a single tadalafil administration significantly reduced systolic BP before and after exercise (p < 0.05), decreased VO2/HR at IVT (13.3 +/- 1.8 vs. 14.5 +/- 2.1 mL . beat (-1); p = 0.03), but did not modify individual VO2max, IVT, or IAT. In healthy athletes, 20 mg of tadalafil does not substantially influence physical fitness-related parameters, exercise tolerance, and cardiopulmonary responses to maximal exercise in normoxia; it remains to be verified if higher doses/prolonged use influence health and/or sport performance in field conditions.

Abstract
Prostaglandins modulate the hypothalamus-pituitary-adrenal and -gonadal axis pathways. We explored the effects of a single course of treatment with acetylsalicylic acid (ASA), an inhibitor of prostaglandin synthesis, on the steroid milieu in athletes. Morning plasma cortisol (F), dehydroepiandrosterone sulphate, free-testosterone, testosterone (T) and their ratios were evaluated before and after the administration of either ASA or placebo in twelve male athletes, when affected by minor musculoskeletal trauma and, as control, after a five/six week wash-out in healthy conditions respectively. One tablet of ASA (800 mg), or placebo, was administered two times daily for 10 days during treatment. All the volunteers suspended exercise training during treatment. The results revealed that compared to placebo, plasma F was significantly lower after ASA treatment (p = 0.023). Furthermore, the comparison of hormone's absolute and percentage of variations (Delta and Delta%) between ASA and placebo treatment showed significant differences respectively for DeltaF (p = 0.045), for DeltaT (p = 0.047), for DeltaT/F (p = 0.042), for DeltaF% (p = 0.04) and for DeltaT% (p = 0.049). Our data suggest that in comparison to placebo, a short-term ASA treatment is able to influence the plasma steroid milieu in athletes. Due to the observed variability of the individual hormonal patterns, further research is required to substantiate these findings.

Abstract
To evaluate the influence of chronological age and pubertal development on the hypothalamus-pituitary-adrenal (HPA) axis response to stress, we studied the possible correlations between male pubertal characteristics and salivary cortisol (C), DHEAS and the DHEAS/C ratio before (pre-stress) and after acute exercise-stress in young male volunteers (no. 87; 13.3+/-2.1 yr). In our overall study population, the mean pre-stress salivary C and DHEAS concentrations, significantly increased after exercise-related stress, whereas the DHEAS/C ratio significantly decreased. Pre-stress salivary C was positively correlated with chronological age, and after-stress salivary C concentration variations were negatively correlated with pubertal stage, mean testis volume and pre-stress salivary DHEAS. Furthermore, salivary DHEAS concentrations and the DHEAS/C ratio, before and after exercise stress, were positively correlated with chronological age, pubertal stage, pre-stress salivary testosterone (T), testis volume and body mass index (BMI). In contrast with late pubertal stages (P4, P5), young individuals at early stages of puberty (P1 to P3) showed higher C increase and lower DHEAS/C ratio after exercise-related stress. In conclusion, since C is also a mediator of stress-related negative effects on health and the DHEAS/C ratio has been hypothesized as an index for the degree to which an individual is buffered against the negative effects of stress, these data might suggest potentially increased stress-related risks at early stages of male puberty.

Abstract
Puberty influences both the performance and the hormonal responses to exercise-related stress. We evaluated the distribution and the correlation between pubertal characteristics and the salivary cortisol (sC) and testosterone (sT) responses to acute physical exercise in young male athletes (13.4 +/- 2.1 yr, n = 110). The mean pre-exercise nmol . L (-1) sC and sT concentrations were 19.08 +/- 4.32 and 0.34 +/- 0.15 and increased to 21.27 +/- 5.51 and 0.41 +/- 0.16 after a 90-min training session (p < 0.01). The sC concentration at rest was positively correlated with chronological age (p < 0.01) and negatively correlated with fat % (p < 0.05), whereas significant negative correlations of DeltasC and DeltasC% after exercise with age, pubertal stage and mean testis volume (p < 0.05) were observed. The sT increase after exercise was correlated with chronological age, pubertal stage and pre-exercise sT levels (p < 0.01), whereas the DeltasT and DeltasT% of increase were negatively correlated with chronological age and resting sT levels (p < 0.05 and p < 0.01). In the present study, we observed the presence of high inter-individual variability of different biological parameters (anthropometry, pubertal stage, hormones, etc.) within athletes selected by chronological age in the same class and the presence of significant correlations between chronological age, puberty and the steroid hormone responses to physical exercise. Our data suggest the need for different criteria in exercise prescription and selection of young athletes and in the evaluation of stress reactivity at puberty.

Abstract
The diagnosis of andropause, currently named partial androgen deficiency of the aging male (PADAM), by the International Society for the Study of Aging Male (ISSAM), is based on the presence of clinical symptoms together with a biochemical evidence of hypogonadism. Thus, the definition of specific diagnostic criteria, both as clinical manifestations and laboratory findings, is fundamental to identify those men for whom androgen replacement therapy should be warranted. Clinical manifestations suspected to be caused by androgen deficiency are numerous (decreased libido and erectile dysfunction, decreased muscle mass and strength, decreased bone mineral density, increased fat mass, depression, fatigue, irritability, etc) and, for these, the linkage to a real hypogonadal state must be confirmed on an individual basis. In this regard, the exact list of reproductive hormones to be evaluated, for screening or for diagnosis confirmation, together with eventual dynamic endocrine test (GnRH, hCG, clomiphene, etc) must be adjusted. Furthermore, the clinician must be aware of the methods and limits of androgen assays in order to be able to specifically select, where possible, those which are validated by comparison to a "gold standard" or accepted method of measurement.

Abstract
Androgenic-anabolic steroids (AAS) is an official definition for all male sex steroid hormones, their synthetic derivatives and their active metabolites. AAS are drugs with specific therapeutic indications, yet they are popularly known because of their worldwide non-therapeutic use in a large number of healthy individuals. Doping with AAS has become so widespread in athletics that it affects the outcome of sports contests. Furthermore, AAS non-therapeutic use is increasing particularly among adolescents and females, becoming one of the main causes of iatrogenic diseases due to drug abuse. All physicians must be aware about the large diffusion and side effects related to AAS non-therapeutic use, in order to discover clinical signs of AAS abuse and/or to start adequate preventive and/or therapeutic actions.

Abstract
To evaluate the role of heredity in the pituitary responses to exercise-related stress, serum ACTH, beta-endorphin, cortisol, GH, and PRL responses to a thirty-minute treadmill exercise at individual anaerobic threshold were evaluated in nine pairs of male monozygotic twin athletes. Hormone evaluations were performed before (-30, -15, 0 pre) and after exercise (0 post, + 15, + 30, + 45, + 60, and + 90 min). The intraclass correlation coefficient (expression of within-pair resemblance) was computed for each hormone before and after exercise as area under curves (AUC), absolute values, and percentage of variation, respectively. The exercise-related stress condition induced a significant increase for all evaluated hormones before (anticipatory response) and/or after exercise. As new data, we observed: 1) A significant within-pair resemblance for exercise-related GH and PRL increase (AUCs and/or absolute values), and for the percentage of variation of cortisol, and 2) the lack of significant resemblance for the observed increase of ACTH, cortisol and absolute beta-endorphin serum concentration. This first co-twin control study supports the hypothesis that, in trained men, there are probably different relative roles for the influence of genetic factors on the pituitary hormones involved in physiological adaptation to exercise-related stress. Furthermore, our findings justify further investigations into this topic.

Abstract
Sports influence the hypothalamus-pituitary-gonadal axis (HPG). The purpose of this study was to analyze the effects of physical stress on qualitative male LH secretion. We evaluated the HPG axis at rest and the LH response to a treadmill exercise (90 % of Vdot;O 2 max) in eight trained (running 50 to 70 km/week) and eight untrained subjects. FSH, total testosterone (T) and free testosterone (FT) were evaluated at rest by radioimmunoassay, whereas serum LH was evaluated both by radioimmunoassay (I-LH) and by a biological assay (RICT, B-LH), before (-30, -15, 0 pre) and after exercise (0 post, + 15, + 30, + 60 min). Semen analysis was performed. The results showed that the B/I LH ratio was significantly lower at rest in athletes than in controls (1.3 +/- 0.5 and 2.1 +/- 0.7 respectively, p < 0.05) and the B-LH and B/I LH ratio were reduced after exercise in controls (from 21.1 +/- 5.7 to 13.9 +/- 3.4 mIU/mL and from 2.3 +/- 0.8 to 1.6 +/- 0.4, at + 60 respectively, p < 0.05). T and FT were significantly lower in athletes compared with controls (4.18 +/- 1.1 vs 5.96 +/- 1.6 ng/ml and 24.3 +/- 4.8 vs 29.7 +/- 5.2 pg/ml respectively, p < 0.05). Semen parameters showed no difference. The B/I LH ratio could be a "marker" of altered LHRH secretion due to an exercise-linked adaptive condition.

Abstract
PURPOSE Prostaglandins (PGs) modulate the activity of the hypothalamus-pituitary axis, and pituitary hormones are largely involved in the physiological responses to exercise. The purpose of this study was to analyze the effects of acetylsalicylic acid (ASA), an inhibitor of PGs synthesis, in the pituitary responses to physical stress in humans. METHODS Adrenocorticotropin (ACTH), beta-endorphin, cortisol, growth hormone (GH), and prolactin (PRL) responses to exercise were evaluated after administration of either placebo or ASA. Blood samples for hormone evaluations before (-30, -15, and 0 pre) and after (0 post, +15, +30, +45, +60, and +90 min) a 30-min treadmill exercise (75% of .VO(2max)) were taken from 12 male athletes during two exercise trials. One tablet of ASA (800 mg), or placebo, was administered two times daily for 3 d before and on the morning of each exercise-test. RESULTS The results clearly show that, compared with placebo, ASA ingestion significantly blunted the increased serum ACTH, beta-endorphin, cortisol, and GH levels before exercise (anticipatory response) and was associated with reduced cortisol concentrations after exercise. Furthermore, although no differences in the GH response to exercise were shown, a significantly reduced total PRL response to stress condition was observed after ASA. CONCLUSION ASA influences ACTH, beta-endorphin, cortisol, GH, and PRL responses to exercise-related stress in humans (preexercise activation/exercise-linked response). Even though it is not possible to exclude direct action for ASA, our data indirectly confirm a role of PGs in these responses. We have to further evaluate the nature of the preexercise endocrine activation and, because of the large use of anti-inflammatory drugs in athletes, whether the interaction between ASA and hormones might positively or negatively influence health status, performance, and/or recovery.

Abstract
It was proposed that lipocalin type prostaglandin D synthase (L-PGD-S), a bifunctional protein both synthesizing PGD2 and transporting retinoids and other lipophilic ligands, could be involved in the development and the maturation of sperm. In the present study, the seminal plasma (SP) of 59 adult males was analyzed by standard WHO methods and immunoblotting, using a monospecific polyclonal antibody directed against L-PGD-S. Briefly, aliquots of SP (2.5 microl), were fractionated by polyacrylamide electrophoresis in the presence of sodium dodecyl sulfate, the blots were stained and densitometrically analyzed. To obtain quantitative data, the aliquot of SP was selected within the linear part of the dose/band intensity curve and a proper quality control was analyzed in all blots to normalize the intensity of the bands of different experiments. A significant reduction (p<0.05) of the L-PGD-S levels was observed in severe oligozoospermic patients compared to normozoospermic subjects and a significant correlation between L-PGD-S levels and sperm concentration was found, as reported by other authors. Further studies are warranted to evaluate the possible diagnostic and pharmacological applications of these observations.

Abstract
The aim of the present study was to evaluate the influence of physical exercise on seminal parameters of male athletes with varicocele. Sixty healthy male volunteers (athletes and non-athletes, n = 30 + 30) and 60 volunteers affected by varicocele (athletes and non-athletes, n = 30 + 30) were randomly selected for a clinical study. All subjects provided at least two semen samples for routine microscopic analysis. Determinations for basal luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, oestradiol, total and free testosterone under resting conditions were also performed. In both groups with varicocele the percentage of total and progressive forward sperm motility and the percentage of normal spermatozoa were significantly reduced. The percentage of both progressive forward motility and normal spermatozoa were significantly lower in athletes with varicocele compared with non-athletes with varicocele (P < 0.05). Only athletes with varicocele had mean left testis volume significantly lower than the contralateral testis (P < 0.05). No modifications of hormonal parameters at rest were observed in any groups. Physical activity might represent an aggravating factor for spermatogenesis in athletes with varicocele. In countries where sport eligibility is granted by an authoritative body, these results suggest the need to establish general medical criteria to guarantee the continuation of an athlete's training whilst at the same time taking care of his reproductive health.

Abstract
PURPOSE To assess phacoemulsification and posterior chamber intraocular lens (IOL) implantation as an effective, safe, and predictable technique for the correction of high myopia. SETTING University Eye Clinic of Verona, Verona, Italy. METHODS A series of 25 eyes with myopia higher than -12.0 diopters (D) had clear lens extraction by phacoemulsification and IOL implantation in the capsular bag. The mean postoperative follow-up was 42.92 months +/- 3.76 (SD). RESULTS No serious intraoperative complications occurred. Uncorrected visual acuity improved in all cases. The mean postoperative best corrected visual acuity improved by an average of 1 line. One case (4.0%) of postoperative retinal detachment (RD) occurred at 12 months. One case (4.0%) of biometric error (3.0 D) occurred. CONCLUSION Clear lens extraction by phacoemulsification and IOL implantation in a series of highly myopic eyes was effective and had an acceptable predictability and a low rate of complications. Careful evaluation of the retinal periphery by indirect ophthalmoscopy is recommended to avoid postoperative RD.

Abstract
The purpose of this study was to delineate the role of GH on serum IGF-I, IGFBP-2 and -3 responses to exercise. Hormones were evaluated in six trained male subjects before (-30, -15, 0), during (+15) and after (+30, +45, + 60, +90 min) a thirty-minutes treadmill exercise (60% VO2max), both after a single administration of a somatostatin analog (i.e., octreotide, 0.1 mg sc) and after saline. The same evaluations were performed without exercise with similar treatments. The results showed that: 1) octreotide significantly inhibited the GH response to exercise, 2) exercise increased IGFBP-3 concentration (+37.4% at +90, p < 0.05), whereas no modification of IGFBP-2 and of IGF-I/ IGFBP-2 and IGFBP-3/IGFBP-2 ratios were observed, 3) octreotide amplified the IGFBP-3 increase after exercise (p < 0.01 vs. exercise, from + 30 to + 60, or octreotide alone) and, without exercise, slightly increased IGFBP-3 (+15% at +75, p < 0.05) and decreased IGF-I (-14.8% at +75, p < 0.01). We concluded that GH has a reduced role, as a stimulating factor, in the serum acute IGFBP-3 increase after exercise and that octreotide is probably able to directly amplify this response. Unfortunately, we can only speculate on the physiological pathways involved.

Abstract
OBJECTIVE To review the efficacy, safety, and proper methods for use of bleach (sodium hypochlorite) as a means of needle disinfection. DATA SOURCES Controlled studies cited in MEDLINE between 1966 and 1999 using indexing terms: needle, bleach, HIV/AIDS, and disinfection. STUDY SELECTION AND DATA EXTRACTION Studies were categorized based on experimental conditions produced and specific testing procedures used. DATA SYNTHESIS Used properly, undiluted bleach (sodium hypochlorite 5.25%) appears to be an effective disinfection solution for used needles. Proper needle disinfection with undiluted bleach may reduce the risk of HIV transmission among injection drug users from needle sharing. CONCLUSION Pharmacists can play a role in reducing HIV transmission among injection drug users by advocating cessation of drug use, drug treatment programs, and avoidance of needle sharing. Pharmacists should be prepared to educate patients who are unwilling to cease illicit drug use or participate in drug treatment programs on the proper methods of bleach disinfection of used needles.

Abstract
ARTICLE ABSTRACT: The concurrent use of anticonvulsants and antiretrovirals is a poorly studied area that poses a therapeutic dilemma for the clinician caring for HIV-positive patients requiring both classes of medications. Anticonvulsants and antiretrovirals may interact through multiple mechanisms including competition for protein binding, enhanced or reduced liver metabolism, and increased viral replication. The authors present many of the challenges faced by clinicians caring for HIV-positive patients who may require anticonvulsant therapy.

Abstract
Antiretroviral drugs have significantly reduced death rates from the acquired immunodeficiency syndrome in the United States. They are highly effective in reducing viral replication, but their utility is threatened by rapid development of drug resistance. Although antiretroviral drug resistance testing is available by either genotyping or phenotyping, no consensus guidelines have been published regarding the appropriate use or interpretation of these new tests. Even though their role in clinical practice is not defined, it is important for clinicians to become familiar with relative advantages and disadvantages of genotypic and phenotypic testing and various mechanisms of antiretroviral resistance.
