Abstract
The CUORE experiment, a ton-scale cryogenic bolometer array, recently began operation at the Laboratori Nazionali del Gran Sasso in Italy. The array represents a significant advancement in this technology, and in this work we apply it for the first time to a high-sensitivity search for a lepton-number-violating process: ^{130}Te neutrinoless double-beta decay. Examining a total TeO_{2} exposure of 86.3 kg yr, characterized by an effective energy resolution of (7.7±0.5) keV FWHM and a background in the region of interest of (0.014±0.002) counts/(keV kg yr), we find no evidence for neutrinoless double-beta decay. Including systematic uncertainties, we place a lower limit on the decay half-life of T_{1/2}^{0ν}(^{130}Te)>1.3×10^{25} yr (90% C.L.); the median statistical sensitivity of this search is 7.0×10^{24} yr. Combining this result with those of two earlier experiments, Cuoricino and CUORE-0, we find T_{1/2}^{0ν}(^{130}Te)>1.5×10^{25} yr (90% C.L.), which is the most stringent limit to date on this decay. Interpreting this result as a limit on the effective Majorana neutrino mass, we find m_{ββ}<(110-520) meV, where the range reflects the nuclear matrix element estimates employed.

Abstract
BACKGROUND Although oral contraceptives (OCs) are one the most widespread therapy in young polycystic ovary syndrome (PCOS) women and physical exercise represents a crucial first step in the treatment of overweight and obese PCOS, no studies were performed to compare the effects on cardiovascular risk (CVR) of OCs and physical exercise in PCOS. OBJECTIVE To compare the effects of OCs administration and physical exercise on the CVR, clinical, hormonal and metabolic parameters in PCOS women. METHODS One hundred and fifty PCOS women were enrolled and were randomized to OCs (3 mg drospirenone plus 30 μg ethinyloestradiol), structured exercise training programme (SETP) or polyvitamin tablets. The intervention phase study was of 6 months. Primary outcome was intima-media thickness (IMT) and flow-mediated dilation (FMD). Secondary outcomes were clinical, hormonal and metabolic changes. RESULTS A significant reduction of IMT and a significant increase of FMD were observed in the SETP group after treatment. Compared to baseline, in the SETP group, a significant improvement in anthropometric measures, insulin sensitivity indexes, lipid profile, cardiopulmonary function, inflammatory markers and frequency of menses was observed. Oral contraceptives use was associated with a significant decrease of hyperandrogenism and a significant improvement of frequency of menses. Further, OCs use had a neutral effect on CVR risk factors. CONCLUSION OCs effectively treat hyperandrogenism and menstrual disturbances, while SETP is more effective in improving cardiometabolic profile and cardiopulmonary function in PCOS.

Abstract
The R&D activity performed during the last years proved the potential of ZnSe scintillating bolometers to the search for neutrino-less double beta decay, motivating the realization of the first large-mass experiment based on this technology: CUPID-0. The isotopic enrichment in [Formula: see text]Se, the Zn[Formula: see text]Se crystals growth, as well as the light detectors production have been accomplished, and the experiment is now in construction at Laboratori Nazionali del Gran Sasso (Italy). In this paper we present the results obtained testing the first three Zn[Formula: see text]Se crystals operated as scintillating bolometers, and we prove that their performance in terms of energy resolution, background rejection capability and intrinsic radio-purity complies with the requirements of CUPID-0.

Abstract
The LUCIFER project aims at deploying the first array of enriched scintillating bolometers for the investigation of neutrinoless double-beta decay of [Formula: see text]Se. The matrix which embeds the source is an array of ZnSe crystals, where enriched [Formula: see text]Se is used as decay isotope. The radiopurity of the initial components employed for manufacturing crystals, that can be operated as bolometers, is crucial for achieving a null background level in the region of interest for double-beta decay investigations. In this work, we evaluated the radioactive content in 2.5 kg of 96.3 % enriched [Formula: see text]Se metal, measured with a high-purity germanium detector at the Gran Sasso deep underground laboratory. The limits on internal contaminations of primordial decay chain elements of [Formula: see text]Th, [Formula: see text]U and [Formula: see text]U are respectively: [Formula: see text]61, [Formula: see text]110 and [Formula: see text]74 [Formula: see text]Bq/kg at 90 % C.L. The extremely low-background conditions in which the measurement was carried out and the high radiopurity of the [Formula: see text]Se allowed us to establish the most stringent lower limits on the half-lives of the double-beta decay of [Formula: see text]Se to 0[Formula: see text], 2[Formula: see text] and 2[Formula: see text] excited states of [Formula: see text]Kr of 3.4[Formula: see text]10[Formula: see text], 1.3[Formula: see text]10[Formula: see text] and 1.0[Formula: see text]10[Formula: see text] y, respectively, with a 90 % C.L.

Abstract
We report the results of a search for neutrinoless double-beta decay in a 9.8 kg yr exposure of (130)Te using a bolometric detector array, CUORE-0. The characteristic detector energy resolution and background level in the region of interest are 5.1±0.3 keV FWHM and 0.058±0.004(stat)±0.002(syst)counts/(keV kg yr), respectively. The median 90% C.L. lower-limit half-life sensitivity of the experiment is 2.9×10(24) yr and surpasses the sensitivity of previous searches. We find no evidence for neutrinoless double-beta decay of (130)Te and place a Bayesian lower bound on the decay half-life, T(1/2)(0ν)>2.7×10(24) yr at 90% C.L. Combining CUORE-0 data with the 19.75 kg yr exposure of (130)Te from the Cuoricino experiment we obtain T(1/2)(0ν)>4.0×10(24) yr at 90% C.L. (Bayesian), the most stringent limit to date on this half-life. Using a range of nuclear matrix element estimates we interpret this as a limit on the effective Majorana neutrino mass, m(ββ)<270-760 meV.

Abstract
CUORE, an array of 988 TeO[Formula: see text] bolometers, is about to be one of the most sensitive experiments searching for neutrinoless double-beta decay. Its sensitivity could be further improved by removing the background from [Formula: see text] radioactivity. A few years ago it was pointed out that the signal from [Formula: see text]s can be tagged by detecting the emitted Cherenkov light, which is not produced by [Formula: see text]s. In this paper we confirm this possibility. For the first time we measured the Cherenkov light emitted by a CUORE crystal, and found it to be 100 eV at the [Formula: see text]-value of the decay. To completely reject the [Formula: see text] background, we compute that one needs light detectors with baseline noise below 20 eV RMS, a value which is 3-4 times smaller than the average noise of the bolometric light detectors we are using. We point out that an improved light detector technology must be developed to obtain TeO[Formula: see text] bolometric experiments able to probe the inverted hierarchy of neutrino masses.

Abstract
Adulthood and childhood obesity is rapidly becoming an epidemic problem and it has a short and long term impact on health. Short term consequences are mostly represented by psychological effects, in fact obese children have more chances to develop psychological or psychiatric problems than non--obese children. The main long term effect is represented by the fact that childhood obesity continues into adulthood obesity and this results in negative effects in young adult life, since obesity increases the risk to develop morbidity and premature mortality. The obesity--related diseases are mostly represented by hypertension, type 2 diabetes, dyslipidaemia, cardiovascular diseases. Medical treatment should be discouraged in childhood because of the side effects and it should be only reserved for obese children with related medical complications. Lifestyle changes should be encouraged in both adulthood and childhood obesity. This review focuses on the management of obesity both in adulthood and in childhood, paying particular attention to lifestyle changes that should be recommended.

Abstract
The excess in physical activity could be closely linked to considerable negative consequences on the whole body. These dysfunctions called as "female athlete triad"' by the American College of Sports Medicine (ACSM) include amenorrhea, osteoporosis and disorder eating. The female athlete triad poses serious health risks, both on the short and on the long term, to the overall well-being of affected individuals. Sustained low energy availability can impair health, causing many medical complications within skeletal, endocrine, cardiovascular, reproductive and central nervous system. On the contrary, several studies have shown, that physical activity improves cardiovascular risk factors, hormonal profile and reproductive function. These improvements include a decrease in abdominal fat, blood glucose, blood lipids and insulin resistance, as well as improvements in menstrual cyclicity, ovulation and fertility, decreases in testosterone levels and Free Androgen Index (FAI) and increases in sex hormone binding globulin (SHBG). Other studies reported that physical activity improved self-esteem, depression and anxiety. Thus, the aim of this review is to elucidate the effect of physical exercise on female reproductive system and viceversa the impact of hormonal status on physical activity and metabolism. In addition this review supports the idea that physical exercise is a helpful tool for the management of obesity, prevention of cardiovascular, metabolic diseases and female reproductive organs related diseases (e.g. breast cancer). When the excess in physical activity leads up to the female athlete triad, it is imperative to treat each component of the triad by employing both pharmacological and non pharmacological treatments.

Abstract
Bariatric surgery is nowadays an effective therapeutic option for morbid obesity. Endocrinologists may thus have a growing opportunity to diagnose and treat obese patients eligible for surgery in pre- and post-operative phase. This requires a better understanding of endocrine changes caused by either obesity or weight loss surgery. Despite the large number of studies available in literature, only limited well-designed clinical trials have been performed so far to investigate changes of endocrine axes following bariatric procedures. There are still areas of unclear results such as female and male fertility, however, weight loss after bariatric surgery is considered to be associated with favorable effects on most endocrine axes. The aim of this clinical review is to overview the available literature on the effects of weight loss after bariatric surgery on the endocrine systems to suggest the most appropriate pre- and post-operative management of obese patients undergoing bariatric surgery in terms of "endocrine" health.

Abstract
Polycystic Ovary Syndrome (PCOS) is characterized by an extreme variety of phenotypes and controversial metabolic implications. Hepatic Steatosis (HS) and low-grade chronic inflammation (LGCI) might be common findings in PCOS. We conducted a cross-sectional study to evaluate the LGCI and HS in young women with PCOS according to their Body Mass index (BMI), Insulin Resistance (IR), and PCOS phenotypes. Sixty young premenopausal PCOS women and 20 age-matched controls participated. Primary outcome measures were the presence/severity of HS; LGCI index evaluated as spleen longitudinal diameter (SLD) by UltraSound, C-Reactive Protein (CRP) and Interleukin (IL)-6 levels; BMI and the Homeostasis Model Assessment (HoMA) of IR. The second outcome measures were testosterone, Sex Hormone-Binding Globulin (SHBG) levels, and Free Androgen Index (FAI). The presence of HS and LGCI was not significantly different between NW and O/O patients, while there were significant differences particularly when the PCOS-women were grouped according to IR or to PCOS phenotypes. At multiple regression adjusted for BMI, HoMA-IR and the spleen size were the major determinants of the severity of HS (β= 0.36, p=0.007, and β= 0.28, p=0.034, respectively). At multiple regression SLD represented the unique predictor of FAI (β=0.32; p=0.018). In young women with PCOS, HS was detected independently from obesity and was well predicted not only by IR but also by spleen size, with variable expression of the liver-spleen axis across the different PCOS subtypes. A possible role of the spleen in determining LGCI also in women with PCOS is emphasized.

Abstract
BACKGROUND Clomiphene citrate (CC) is the first-line therapy for the induction of ovulation in infertile women with polycystic ovary syndrome (PCOS), but ∼20% of patients are unresponsive. The aim of the current study was to test the hypothesis that a 6-week intervention that consisted of structured exercise training (SET) and hypocaloric diet increases the probability of ovulation after CC in overweight and obese CC-resistant PCOS patients. METHODS A cohort of 96 overweight and obese CC-resistant PCOS patients was enrolled consecutively in a three-arm randomized, parallel, controlled, assessor-blinded clinical trial. The three interventions were: SET plus hypocaloric diet for 6 weeks (Group A); 2 weeks of observation followed by one cycle of CC therapy (Group B); and SET plus hypocaloric diet for 6 weeks, with one cycle of CC after the first 2 weeks (Group C). The primary end-point was the ovulation rate. Other reproductive data, as well as anthropometric, hormonal and metabolic data, were also collected and considered as secondary end points. RESULTS After 6 weeks of SET plus hypocaloric diet, the ovulation rate was significantly (P =0.008) higher in Group C [12/32 (37.5%)] than in Groups A [4/32 (12.5%)] and B [3/32 (9.4%)] with relative risks of 3.9 [95% confidence interval (CI) 1.1-8.3; P = 0.035] and 4.0 (95% CI 1.2-12.8; P = 0.020) compared with Groups A and B, respectively. Compared with baseline, in Groups A and C, a significant improvement in clinical and biochemical androgen and insulin sensitivity indexes was observed. In the same two groups, the insulin sensitivity index was significantly (P < 0.05) better than that in Group B. CONCLUSIONS In overweight and obese CC-resistant PCOS patients, a 6-week intervention of SET and a hypocaloric diet was effective in increasing the probability of ovulation under CC treatment. The study was registered at Clinicaltrials.gov:NCT0100468.

Abstract
BACKGROUND The cellular abundance of the phosphoprotein enriched in diabetes (PED/PEA-15), a 15 kDa protein related to insulin resistance (IR), is increased in women with polycystic ovary syndrome (PCOS). AIM To investigate whether metformin (MET) has additive effects on PED/PEA-15 protein levels. MATERIAL/SUBJECTS AND METHODS This is an open label, prospective clinical study over 6 months. Ten hyperandrogenic obese PCOS women [age: 24.6+/-1.6 yr; body mass index (BMI): 30.7+/-1.2 kg/m(2)] were treated with MET (1250 mg/day). Ten age- and BMI-matched normo-androgenic women were used as controls. Outcome measures are: PED/PEA-15 protein levels, fasting plasma glucose and insulin (FPI), reciprocal index of homeostasis model assessment of insulin resistance (1/HOMA-IR); quantitative insulin sensitivity check index (QUICKI); wholebody insulin sensitivity index (ISI); SHBG; total testosterone; free androgen index (FAI). RESULTS At baseline FPI and PED/PEA- 15 protein levels were higher, while 1/HOMA-IR, QUICKI, and ISI were lower (p<0.001) in MET group than in controls. After treatment, independently of body weight and hyperandrogenism, FPI, and PED/PEA-15 protein levels decreased (p=0.001 and 0.004, respectively), while, 1/HOMA-IR, QUICKI, and ISI increased (p<0.001). PED/PEA-15 protein levels correlated significantly with ISI either before (r=0.636; p=0.048), and after treatment (r=0.758; p=0.011). CONCLUSIONS PED/PEA-15 protein levels reduced after a short course of treatment with MET in a group hyperandrogenic obese PCOS women. This effect was independent of body weight and hyperandrogenism, and correlated with ISI, thus adding a further benefit to obese PCOS women.

Abstract
OBJECTIVE To study the impedance to blood flow through the uterine artery in pregnant women with polycystic ovary syndrome (PCOS), and to evaluate its predictive value for adverse pregnancy and perinatal outcomes in this population. DESIGN Prospective case-control study. SETTING Academic Departments of Obstetrics and Gynaecology in Italy. POPULATION Seventy-three pregnant women with ovulatory PCOS (PCOS group) and 73 age- and body mass index-matched healthy pregnant controls (control group). METHODS Serial Doppler velocimetry measurements of the uterine artery. MAIN OUTCOME MEASURES Blood flow impedance indices and pregnancy/perinatal outcomes. RESULTS A significantly (P < 0.05) higher rate of subjects with abnormal velocimetry findings was observed in the PCOS group than in the control group. In the PCOS group, the pulsatility index (PI) at first (P = 0.042) and mid-second (P = 0.039) trimesters of pregnancy, and bilateral notch at first (P = 0.025) and mid-second (P = 0.007) trimesters of pregnancy, were the strongest independent predictors of adverse outcomes. Conversely, in the control group, PI at the first trimester of pregnancy was a predictor of adverse outcomes only when combined with bilateral notch (P = 0.042), whereas at mid-second trimester of pregnancy PI (P = 0.033) and bilateral notch (P = 0.048) were independent predictors of adverse outcomes. CONCLUSIONS Uterine artery Doppler indices are more commonly altered in pregnant patients with PCOS than in controls, showing a high predictive value for abnormal pregnancy/perinatal outcomes.

Abstract
BACKGROUND Lifestyle modifications are successfully employed to treat obese and overweight women with polycystic ovary syndrome (PCOS). The aims of the current pilot study were (i) to compare the efficacy on reproductive functions of a structured exercise training (SET) programme with a diet programme in obese PCOS patients and (ii) to study their clinical, hormonal and metabolic effects to elucidate potentially different mechanisms of action. METHODS Forty obese PCOS patients with anovulatory infertility underwent a SET programme (SET group, n = 20) and a hypocaloric hyperproteic diet (diet group, n = 20). Clinical, hormonal and metabolic data were assessed at baseline, and at 12- and 24-week follow-ups. Primary endpoint was cumulative pregnancy rate. RESULTS The two groups had similar demographic, anthropometric and biochemical parameters. After intervention, a significant improvement in menstrual cycles and fertility was noted in both groups, with no differences between groups. The frequency of menses and the ovulation rate were significantly (P < 0.05) higher in the SET group than in diet group but the increased cumulative pregnancy rate was not significant. Body weight, body mass index, waist circumference, insulin resistance indexes and serum levels of sex hormone-binding globulin, androstenedione and dehydroepiandrosterone sulphate changed significantly (P < 0.05) from baseline and were significantly different (P < 0.05) between the two groups. CONCLUSIONS Both SET and diet interventions improve fertility in obese PCOS patients with anovulatory infertility. We hypothesize that in both interventions an improvement in insulin sensitivity is the pivotal factor involved in the restoration of ovarian function but potentially acting through different mechanisms.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting 5-10% of reproductive aged women, about 1 out of 15 women worldwide. Traditionally it was considered as a reproductive disorder showing hyperandrogenism, chronic anovulation and infertility; it is now well accepted that PCOS represents a ''multifaceted'' syndrome with substantial metabolic and cardiovascular long term consequences. Several PCOS women present abdominal adiposity (visceral fat) with a level of peripheral insulin resistance (IR), similar to that present in women with type 2 diabetes, in association with an increased incidence of impaired glucose tolerance. Several cardiovascular risk factors are often related to metabolic alterations, such as dyslipidemia, hypertension, endothelial dysfunction, low grade chronic inflammation, that are present even at early age in PCOS women. Pathogenetic mechanisms of these impairments are not completely clarified yet, but IR appears to play a critical role, such as the key factor linking hypertension, glucose intolerance, obesity, lipid abnormalities and coronary artery disease. In conclusion, although increased incidence of metabolic abnormalities and metabolic disease like type 2 diabetes, and several cardiovascular abnormalities have been widely demonstrated in PCOS women, larger and multicenter trials of long term cardiovascular outcomes are required to better define the incidence of cardiovascular risk and cardiovascular disease in PCOS.

Abstract
Metformin, an insulin sensitizer widely used for the treatment of patients with type-2 diabetes mellitus (DM), was recently introduced in the clinical practice to treat women with polycystic ovary syndrome (PCOS). The aim of the current review was to evaluate the current role of metformin in the treatment of the PCOS-related disorders. The Authors analyze here the administration of metformin for treating the ovarian dysfunction due to PCOS, and show the evidences available in literature regarding its alternative uses.

Abstract
In patients affected of polycystic ovary syndrome (PCOS), obesity has an high percent of incidence and represents an important factor increasing its clinic evolution, both in metabolic than in reproductive terms. For these patients non pharmacologic treatments aimed at the reduction of body weight, such as diets and physical exercise, represent the first line therapeutic approach. The aim of this review is to analyze the changes in life style and to highlight their efficacy in reducing the negative effects of PCOS on metabolism and reproductivity. Specifically different types of diet have been compared, in health or PCOS women, such as low glycemic index diets, moderate carbohydrate, high protein and low fat diets, very low carbohydrate and high fat diets and, finally, moderate carbohydrate and high monounsaturated fat diets. In the global view of the approach to the disease, different regimens of physical activity and the usefulness of a behavior therapy were also evaluated. Results obtained in health women suggest that diets higher in proteins and lower in carbohydrates are to be preferred to the conventional diet lower in fats and higher in carbohydrates. Anyway other studies are necessary to justify a similar assertion in women with PCOS. At the same way, the optimum regimen of physical exercise for PCOS women is still to be demonstrated.

Abstract
Obesity is an increasingly important worldwide health problem, representing the major risk factor for coronary heart disease. The increase in the prevalence of obesity, particularly among younger age groups, is likely to have long-term implications for cardiovascular disease (CVD) in the years to come, especially at a young age. Obesity plays a central role in the insulin resistance (IR) syndrome and increases the risk of atherosclerotic CVD. The present review will examine the relationships among cardiovascular risk (CVR) factors during the childhood-adolescence-adulthood transition. In fact, the relation between obesity, in particular visceral obesity and CVD, appears to develop at a relatively young age. The foremost physical consequence of obesity is atherosclerotic CVD, and an intriguing example of obesity-related cardiovascular complications affecting young women is the polycystic ovary syndrome (PCOS).

Abstract
This study was designed to assess the relationship between mutations in the FSH receptor (FSHr) gene and polycystic ovary syndrome (PCOS) in Italian women. The study population included 50 patients with PCOS and 50 age- and body mass index (BMI)-matched controls. A complete anthropometrical, hormonal and pelvic ultrasonographic evaluation was performed in all subjects. Genomic DNA was extracted from peripheral lymphocytes and then each exon of the FSHr gene was amplified by PCR. The mutation identified was cloned and the functional properties were studied after transient expression in COS-7 cells. Direct sequencing of exons 1-10 of the FSHr gene revealed the presence of a heterozygous AAT/ATT mutation affecting the isoleucine residue at position 411, which was replaced by an asparagine, in the second transmembrane segment (I411N). This mutation was only found in one woman with PCOS and not in her parents. This mutation was not present in 50 age and BMI controls and in another 150 women not affected by PCOS. The functional study after transient expression in COS-7 cells revealed that this I411N had similar functional characteristics with respect to the wild type FSHr (wtFSHr). Genetic analyses of polymorphisms in the human FSHr gene were also performed. All 50 women with PCOS harbored the A307T polymorphic variant, 56% harbored N680S, 30% S680S and 14% N680N polymorphisms. In conclusion, the present study demonstrates that mutations of the FSHr gene are rare in Italian women. The only mutation that we found does not appear to have any pathophysiological significance in PCOS.

Abstract
Although thyroid disorders related to the end-stage renal disease (ESRD) are well known, there are discordant data on the function and morphology of the thyroid gland after renal transplantation (RT). The objective of this cross-sectional, case-control study was to investigate the prevalence and risk factors for disorders in the thyroid function and morphology after a successful RT. Fifty consecutive patients (25 females, 25 males) with fully functioning allograft were enrolled. Their age at transplant ranged from 23 to 44 yr (median, 38) and their post-RT follow-up lasted 15-86 months (median, 23). One hundred healthy subjects matched for sex, age and body mass index (BMI) were included as controls. Serum free thyroid hormones, TSH, thyroglobulin, thyroid hormone-binding globulin (TBG) and iodine urinary excretion were determined; ultrasonographic exam of the thyroid gland was performed in all subjects. Age, gender, time elapsed from RT, dialysis duration, kidney function, type of immunosuppression and corticosteroid dose were considered as possible influencing factors for the thyroid function. Hypothyroidism was found in 6% of patients, "low T3 syndrome" in 52%, while another 26% had free T3 (FT3), free T4 (FT4) and TSH in the lowest third of the normal range, suggesting inhibition of the whole hypothalamic-pituitary-thyroid (HPT) axis. Iodine excretion and prevalence of anti-thyroid antibodies were similar in both patients and controls. There was no significant difference in the thyroid function according to different immunosuppressive regimens. In patients, an ultrasonographic exam revealed a very variable thyroid volume ranging from 7.2 to 24.8 ml. Solid nodules were detected in 12 (24%) cases and cystic lesions in another four (8%); they were proven negative at cytological examination. Dialysis duration was longer in patients with thyroid nodules than in those without (p<0.05). Inhomogeneous hypoechoic pattern typical for chronic thyroiditis was more frequent than its biochemical expression. In conclusion, a high prevalence of abnormal thyroid morphology was found in patients after a successful RT, being partly related to a previous uremia. Abnormalities in the thyroid function are likely an expression of the post-transplant general and immunological conditions. Endocrinological follow-up is advisable in patients after RT, in order to discriminate thyroid dysfunctions which need specific treatments from those that can only be followed-up, avoiding inappropriate treatments of biochemical abnormalities.

Abstract
Morbidly obese subjects are characterized by multiple endocrine abnormalities and these are paralleled by unfavorable changes in body composition. In obese individuals, either 24-h spontaneous or stimulated GH secretion is impaired without an organic pituitary disease and the severity of the secretory defect is proportional to the degree of obesity. The GHRH+arginine (GHRH+ARG) test is likely to be the overall test of choice in clinical practice to differentiate GH deficiency (GHD) patients. Similarly to other provocative tests, GHRH+ARG is influenced by obesity per se. Therefore, a new cut-off limit of peak GH response of 4.2 microg/l in obese subjects has been recently assumed. The aim of the present study was to investigate the reciprocal influence between decreased GH secretion and body composition in a group of 110 morbidly obese subjects, using the new cut-off limit of peak GH response to GHRH+ARG test for these subjects. In our study, GHD was identified in 27.3% of the obese subjects, without gender difference. In GDH obese subjects body mass index (BMI), waist circumference, waist-to-hip ratio (WHR), fat mass (FM), and resistance (R) were higher while reactance (Xc), phase angle, body cell mass (BCM), IGF-I, or IGF-I z-scores were lower than in normal responders (p<0.001). In all obese subjects, GH peak levels showed a negative correlation with age, BMI, waist circumference and FM, and a positive correlation with IGF-I. In the stepwise multiple linear regression, waist circumference and FM were the major determinants of GH peak levels and IGF-I. In conclusion, using the new cut-off limit of peak GH response to GHRH+ARG test for obese subjects, about 1/3 morbidly obese subjects were GHD. GHD subjects showed a significantly different body composition compared with normal responders, and the secretory defect was correlated to different anthropometric variables with waist circumference and FM as the major determinants.

Abstract
Ovarian failure after allogeneic stem cell transplant (allo-SCT) is an important risk factor for development of osteoporosis. We investigated the effects of various antiresorptive treatments in long-term surviving females with ovarian failure after allo-SCT. A total of 60 women with osteoporosis or osteopenia were divided randomly into four groups of 15 women each. Group 1 was treated with calcium and vitamin D alone, group 2 received the same treatment in combination with hormone replacement therapy (HRT), group 3 received risedronate (35 mg weekly, orally for 1 year) and group 4 zoledronic acid (3 monthly doses of 4 mg (intravenous)). All groups were similar for age, body mass index, underlying disease and time elapsed from transplant. Lumbar and femoral bone mineral density (BMD) were measured at baseline and after 12 months, together with serum osteocalcin and urinary hydroxyproline. At 12 months, a significant decrease in lumbar and femoral BMD was observed in group 1 and a milder decrease in group 2. Risedronate treatment increased significantly lumbar BMD and prevented bone loss at the femoral neck. Zoledronic acid increased significantly both lumbar and femoral BMD. In groups 3 and 4 the hydroxyproline excretion was significantly reduced, while osteocalcin mildly increased only in group 4. In conclusion, bisphosphonate administration is useful to prevent and treat bone demineralization in young adult women after allo-SCT.

Abstract
PURPOSE Polycystic ovary syndrome (PCOS) is an extremely prevalent disorder in which elevated blood markers of cardiovascular risk and altered endothelial function have been found. This study was designed to determine if abnormal carotid intima-media thickness (IMT) and brachial flow-mediated dilation (FMD) in young women with PCOS may be explained by insulin resistance and elevated adipocytokines. METHODS A prospective study in 50 young women with PCOS (age: 25.2 +/- 1 years; body mass index [BMI]: 28.7 +/- 0.8) and 50 matched ovulatory controls (age: 25.1 +/- 0.7 years; BMI: 28.5 +/- 0.5) was performed. Carotid IMT, brachial FMD, and blood for fasting glucose, insulin, leptin, adiponectin and resistin were measured. RESULTS PCOS, IMT was increased (P <.01), FMD was decreased (P <.01), fasting insulin was increased (P <.01), QUICKI (a marker of insulin resistance) was decreased (P <.01), and adiponectin was lower (P <.05), whereas leptin and resistin were not different compared with matched controls. Whereas BMI or waist/hip ratios did not correlate with IMT or FMD, insulin and QUICKI correlated positively and negatively with IMT (P <.01). There was a significant negative correlation between adiponectin and IMT (P <.05). These correlations were unchanged when adjusting for BMI and the correlation between IMT and adiponectin was unaffected by insulin resistance parameters. CONCLUSIONS These data suggest that young women with PCOS have evidence for altered endothelial function. Adverse endothelial parameters were correlated with insulin resistance and lower adiponectin. Both insulin resistance and adiponectin appear to be important parameters. It is hypothesized that the type of fat distribution may influence these factors.

Abstract
UNLABELLED In humans, dehydroepiandrosterone (DHEAS) has been postulated to have anabolic and lipolytic properties that could potentially counteract the catabolic effect of cortisol. DHEAS secretion is reduced in morbid obesity, likely due to hyperinsulinemia, and laparoscopic adjustable gastric banding (LASGB), by inducing considerable and rapid weight loss, reduces insulin levels. To investigate the role of decreased insulin levels after LASGB-induced weight loss on DHEAS levels and on body composition changes, we studied 30 pre-menopausal morbidly obese women (BMI ranging 37-62 kg/m2) before, 6, 12 and 24 months after LASGB. Total body water (TBW), fat-free mass (FFM) and fat mass (FM) were measured by bioelectrical impedance analysis; tissue hydration was also assessed by impedance vector analysis. At study ending, the subjects had a total weight loss of 28% of baseline body weight (15% after 6 months). After LASGB, weight loss was mainly due to decreased FM, and TBW, FFM, and body hydration were not significantly reduced. Weight loss was associated with an 82% rise in serum DHEAS already after 6 months while cortisol, cortisol/DHEAS molar ratio, and insulin levels fell by 5.5, 62 and 50%, respectively, after 6, 12 and 24 months (p<0.05). CONCLUSIONS LASGB associated with a well balanced low-calorie diet permits a satisfactory 2-yr weight loss, sparing FFM and without body fluid alterations. As the result of a stable weight reduction program weight loss is associated to decrease in cortisol, cortisol/DHEAS molar ratio, and insulin plasma levels with marked rise in DHEAS. Higher cortisol/DHEAS molar ratio values at baseline are also associated to lower weight loss after LASGB, with lower decrease in FM and higher reduction in FFM and body cell mass, in spite of no differences in dietary regimes. Cortisol/DHEAS molar ratio is likely to represent a reliable marker of favourable modifications in body composition.

Abstract
BACKGROUND Adipocytokines are produced by adipose tissue and have been thought to be related to insulin resistance and other health consequences. We measured leptin, adiponectin, and resistin simultaneously in women with polycystic ovary syndrome (PCOS) and age- and weight-matched controls. Our hypothesis was that these simultaneous measurements would help determine whether adipocytokine secretion is abnormal in PCOS independent of body mass and whether these levels are related to insulin resistance as well as other hormonal changes. METHODS Fifty-two women with PCOS and 45 normal ovulatory women who were age- and weight-matched were studied. Blood was obtained for adipocytokines (leptin, adiponectin, and resistin) as well as hormonal parameters and markers of insulin resistance as assessed by the quantitative insulin-sensitivity check index. Body mass index (BMI) was stratified into obese, overweight, and normal subgroups for comparisons between PCOS and controls. RESULTS Adiponectin was lower (P < 0.05) and resistin was higher (P < 0.05) while leptin was similar to matched controls. Breakdown of the groups into subgroups showed a strong body mass relationship for leptin with no changes in resistin although adiponectin was lower in PCOS, even controlling for BMI. In controls, leptin and adiponectin and leptin and resistin correlated (P < 0.05) but not in PCOS. In controls, all adipocytokines correlated with markers of insulin resistance but not in PCOS. CONCLUSIONS When matched for BMI status, decreased adiponectin in PCOS represent the most marked change. This alteration may be the result of altered adipose tissue distribution and function in PCOS but no correlation with insulin resistance was found.

Abstract
Osteoporosis is a common disorder, especially among elderly post-menopausal women. Elderly women are often affected by co-morbidities, impaired gastrointestinal function and reduced mobility; therefore, the treatment strategy for their osteoporosis can be difficult. In this randomized pilot study, we have investigated the effects of a 12-month treatment with neridronate on bone mineral density (BMD), bone turnover markers and quality of life (QoL). The study included 40 women (age, 65-80 yr; post-menopausal period, >15yr) from a single osteoporosis centre. Twenty women received a monthly im injection of 25 mg of neridronate associated with a daily dose of 500 mg of calcium and 400 U of vitamin D. Twenty women received calcium plus vitamin D supplements alone. Changes in BMD at the lumbar spine and femoral neck were measured by dual energy X-ray absorptiometry. Serum type I collagen C-telopeptide (sCTX), urinary free-deoxypyridinoline (ufDPD), bone alkaline phosphatase (ALP) and serum osteocalcin levels were determined. For the QoL assessment, the Italian version of the SF-36 test was administrated. Spine and hip BMD rose by 6.6 +/- 3 and 4.2 +/- 2.3%, respectively (p < 0.05), after 12 months of neridronate treatment. Markers of skeletal turnover significantly fell already after 3 months of neridronate treatment and decreased progressively thereafter within 12 months. The mean decrease at 12 months ranged from 38 +/- 11% for sCTX to 25.2 +/- 15% for ufDPD (p < 0.001, all). The mean improvement in QoL in the treated group was 45.7% for bodily pain, 37.5% for general health perception, 23.1% for vitality, 18% for emotional role functioning and 12% for physical role functioning. The changes observed in BMD, turnover markers and QoL in the untreated group were ns. The intermittent neridronate administration was easily manageable and well tolerated. In conclusion, neridronate currently represents a valid option for the treatment of osteoporosis, since it helps just as much as oral BPs in the improvement of BMD and in particular conditions it can be even more effective.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine diseases affecting women of fertile age, and is characterized by hyperandrogenism, chronic anovulatory cycles and oligomenorrhea or amenorrhea. Given the repercussions of chronic anovulation on sterility, PCOS is a heavy social burden. Here we describe the procedures used to induce ovulation in PCOS patients, the surgical approach and medical treatments that are still being experimented.

Abstract
BACKGROUND AND AIM To evaluate the prevalence of goitre by means of urinary iodine excretion, palpatory and ultrasonographic thyroid examinations in a heterogeneous population living by the sea. METHODS AND RESULTS We used a special self-administered questionnaire to evaluate thyroid size, iodine intake, eating habits and cardiovascular risk factors in 600 subjects with a mean age of 45 +/- 17 years: 253 men (42.3%) and 347 women (57.7%). Urinary iodine excretion was low (72.1 +/- 15.7 microg/L; median 71.2) and associated with ultrasonographic evidence of an enlarged thyroid (16%) or structural thyroid abnormalities (30%), thus allowing us to define the Salerno Gulf as a mild-moderate area of endemic goitre. All of the subjects ate a Mediterranean diet, with a mean of two portions of fish/week. The cardiovascular risk factors considered were obesity, cigarette smoking, hypertension, hypercholesterolemia, hypertriglyceridemia and diabetes, the prevalences of which were in line with those reported in other studies of similar age-matched populations. CONCLUSIONS The moderate intake of fish and the consumption of a Mediterranean diet did not prevent goitre. Iodine deficiency and subsequent goitre endemia are also present at sea level, probably because of a diet based on local products grown on soil with a low iodine content or possible seawater, soil and air environmental pollution that may interfere with the availability of iodine. The assessment of iodine deficiency should therefore involve the entire population and not only subjects living far from the sea.

Abstract
Polycystic ovary syndrome (PCOS) is a common cause of hyperandrogenism in adolescent girls. In its complete post menarchal expression, the syndrome is characterized by the association of typical clinical, biological, and ultrasonographic findings. Many factors have contributed to our knowledge of different clinical forms of PCOS in adolescent girls. They are helpful for clarifying misleading situations in a period of life when diagnosis of PCOS implies a treatment for many years and may interfere with gynecological outcome. During the last 3 years, we had the opportunity to manage in our unit 45 adolescent girls with ovarian hyperandrogenism: 32 of them had PCOS and the other 13 functional ovarian hyperandrogenism defined by clinical and biological hyperandrogenism without ultrasonographic abnormality. In this review, we report, from our personal experience as well as from recent literature data, the different clinical expressions of PCOS in the pubertal period: the classical post menarchal form, the exceptional pre menarchal form, the post precocious pubarche and the post precocious puberty forms, the familial expression as well as the dominant metabolic expression.

Abstract
A case of unusual combination of polycystic ovaries (PCO), adrenal non-functioning adenoma and severe hirsutism in a young woman from Southern Italy is reported here. A 18-yr-old woman was referred to our Department because of oligomenhorrea, acne and severe hirsutism. During evaluation of the cause of her symptoms, PCO and small left adrenal adenoma were revealed. Although adrenal androgen excess has been shown to dysregulate the hypothalamic-pituitary-gonadal axis, causing PCO-like syndrome, normal circulating androgen values were found. Androgens and cortisol levels were completely suppressed by low-dose dexamethasone test, excluding autonomous steroid secretion by the adrenal mass. Normal response of cortisol and adrenal androgens to corticotropin stimulation test permitted the exclusion of functional adrenal hyperandrogenism. Despite normal LH/FSH ratio, anovulatory cycles were revealed by persistently low progesterone values. Glucose and insulin response to oral glucose tolerance test did not differ from those of normal population. The patient showed an improvement of acne and hirsutism on therapy with estro-progestins (EP). In conclusion, despite normal pattern of serum androgens and LH/FSH ratio, this patient had anovulatory cycles and good response to the EP treatment. These findings suggest that ultrasonography evidence of PCO together with anovulatory cycles contributed to her clinical picture whereas adrenal adenoma seemed to have no relevant role. This case report underlines the need of cautious interpretation of imaging results and clinical signs of severe hirsutism, reminding one that the true cause of a medical problem may not be the most evident.

Abstract
In this prospective randomized study we evaluated the effect of risedronate, an aminobisphosphonate, on bone mass and turnover in patients who had undergone allogeneic stem cell transplant (SCT) for hematological malignancies. Thirty-four patients (18 females, 16 males, age 32+/-10 years) with bone mineral density (BMD) </=-1.5 SD as a T-score at least 6 months after SCT were treated with calcium 1 g/day and vitamin D 800 IU/day and randomized to receive ( n=17, group 1) or not receive ( n=17, group 2) oral risedronate 5 mg/day. The duration of treatment was 12 months. After 6 months, lumbar BMD increased by 4.4+/-1.6% in patients of group 1 and decreased by 4.3+/-1.5% in those of group 2 ( P<0.05); at the femoral neck, BMD did not change significantly in patients of group 1 (+1.2+/-1.2%), while it decreased in those of group 2 (-4.3+/-2.1%; P<0.05). After 12 months, lumbar BMD further increased (+5.9+/-1.7%, P<0.05), compared to baseline in group 1 and slightly increased (+1.1+/-1.4%) in group 2. No further changes were observed at femoral neck in both groups. In conclusion, treatment with risedronate for 12 months increased BMD significantly at the lumbar spine and prevented further bone loss at the femoral neck in long-term survivors after allo-SCT.

Abstract
The aim of this study was to investigate the direct involvement of hyperinsulinaemia, DHEA and DHEA-S [DHEA(S)] in severe obesity in early carotid atherosclerosis, measured as intima-media thickness (IMT). Seventeen normotensive premenopausal women with very high BMI (43.5 +/- 1.6 kg/m2) were recruited for the study. Six women were also evaluated 12 months after laparoscopic adjustable silicone gastric banding (LASGB). Dietary intake, fasting plasma lipid profile, glycemic and insulinemic response to the OGTT, adrenal secretion, at baseline and after ACTH stimulation test, were measured. IMT, common carotid diameter (CD) and left ventricular mass index (LVMi) were measured by B-mode echotomography. All obese subjects showed higher fasting and stimulated insulin levels, but lower DHEA(S) levels than controls, showing a negative correlation between both fasting and stimulated insulin and DHEA(S), either at baseline or after ACTH testing. IMT was higher (p < 0.05) than controls, with a positive correlation with stimulated insulin (p < 0.05) and a strong negative correlation with DHEA(S) (p < 0.001). In a multiple linear regression analysis, insulin response to OGTT maintained an association with DHEA(S) independent of fasting insulin, while DHEA maintained the association with IMT independent of stimulated insulin (p < 0.0001). In the six patients evaluated 12 months after LASGB, fasting insulin levels decreased, while DHEA(S) levels increased (p < 0.05). In conclusion, an early cardiovascular involvement was detected in this group of severe obese with hyperinsulinaemia and low DHEA(S), even in the absence of other well known CVD risk factors.

Abstract
Few and unclear data are available in the literature about the relationship between impairment of GH/IGF-I axis and polycystic ovary syndrome (PCOS). This study was aimed to evaluate the basal GH and IGF- levels, and GH release after challenge test in obese and overweight women with PCOS. Thirty patients with PCOS and other 30 healthy women matched for age, body mass index (BMI) and waist-hip ratio (WHR) were studied. Serum follicle-stimulating hormone (FSH), LH, PRL, E2, P, 17OH-progesterone (17OH-P), total T, delta4, DHEA-S, SHBG, GH and IGF-I levels were evaluated in each subject. A GHRH plus arginine challenge test was performed in all subjects. After provocative test, in PCOS and control women the GH levels were significantly (p<0.05) higher in comparison to basal values from 30 min to 120 min. At the same times, a significant (p<0.05) difference was observed between women with PCOS in comparison to healthy women. The mean peak value of GH resulted significantly (p<0.05) lower in PCOS women in comparison to healthy women. The total GH response (area under curve, AUC) to GHRH plus arginine test resulted significantly (p<0.05) lower in PCOS than in healthy women. These findings were statistically significant (p<0.05) also considering the distinction in obese and overweight women. The AUC for GH secretion was significantly lower (p<0.05) in obese in comparison to overweight subjects in the control group, whereas no significant difference was detected between obese and overweight women in the PCOS group. In conclusion, in PCOS women there is a BMI-independent alteration of the GH levels. Further investigations will be necessary to establish the real cause of these data.

Abstract
Immune function in acromegalic patients has been poorly investigated. The aim of this study was to evaluate the main surface antigen clusters of circulating lymphocytes in acromegaly. One hundred patients with active acromegaly (55 women and 45 men, aged 20-70 yr) and 200 healthy subjects sex- and age-matched with the patients (110 women and 90 men, aged 20-70 yr) were enrolled in this study. All patients and controls were born and live in Southern Italy. No patient had received octreotide, bromocriptine or corticosteroids for at least 3 months before entering the study. The analysis of lymphocyte subset pattern was performed by flow cytometry and fluorescein isothiocyanate or phycoerythrin directly conjugated monoclonal antibodies specific for the cell surface antigen clusters (CD) representing T-cell population as a whole (CD3), T helpers (CD4), T suppressors (CD8), natural killer cells (CD16) and B-cell population as a whole (CD19). Acromegalics had significantly increased levels of CD3 (67.1+/-7.2 vs 64.3+/-8.8%; p=0.03) and CD4 (37.8+/-3.5 vs 36.4+/-4.3%; p=0.004) and decreased levels of CD8 (31.4+/-3.3 vs 33.7+/-8.2%; p<0.01) and CD19 (12.1+/-3.1 vs 15.2+/-5.1; p=0.01) without age-difference. The results of the current study demonstrate an increase in T-cell activity together with a decrease in B-cell activity in a very large series of patients with active acromegaly. These data further support the existence of abnormalities of the immune system in patients with chronic GH/IGF-1 excess.

Abstract
AIM The aim of this study was to investigate the effect of baclofen administration on growth hormone (GH) secretion during different phases of the menstrual cycle. METHODS Twelve healthy women (33.6 +/- (SD) 2.8 years; range 23-40 years) with regular menstrual cycles were enrolled. The phases of the menstrual cycle were determined using transvaginal ultrasonography (TV-US) and detecting hormonal serum levels. Plasma GH levels were evaluated during the early follicular, periovulatory and luteal phases of the cycle before and after the baclofen challenge test. RESULTS After acute baclofen administration, GH levels increased significantly (p < 0.001) compared to basal values during the periovulatory and luteal phases, while no significant variation was detected during the early follicular phase. In addition, plasma GH levels resulted significantly (p < 0.001) higher during the luteal phase than during the periovulatory phase. CONCLUSION Acute baclofen administration induces a significant increase in plasma GH levels in healthy females during the periovulatory and luteal phases, but not during the early follicular phase. These data suggest a modulator role of plasma sex steroids levels on GH release induced by baclofen.

Abstract
The human immortalized prostatic cell line PNT1A has been proved to be a good model for analysis of cellular processes such as the prostatic epithelium proliferation in response to androgens and growth factors. Here we used this cell line for studying the transcriptional activity and trafficking of the androgen receptor (AR) by analyzing several actions of antiandrogens. Transient transfection experiments with PNT1A cells were performed with wild type human AR and an androgen-responsive gene reporter. We demonstrated that the transcription of reporter gene could be triggered by natural androgens (testosterone and dihydrotestosterone) in PNT1A cells as well as in the prostatic carcinoma cell line DU-145. With competitive experiments in the two cell lines, we observed no difference between the antagonistic capacity of cyproterone acetate (CPA) and hydroxyflutamide at 10(-7) M. At this concentration, bicalutamide antagonist activity was lower. In parallel, we compared the subcellular localization of the modified green fluorescent protein (EGFP)-AR in COS-7, PNT1A and DU-145 cell lines under fluorescence microscopy: we found different distributions between nucleus and cytoplasm, depending on the cell line and the culture medium. Androgen induced cluster formation within the nucleus of the PNT1A and DU-145 cells. However, the cytonuclear trafficking of androgen bound EGFP-AR in the same living cell and nuclear foci were easier to examine in the PNT1A cells. The antiandrogen capacity of bicalutamide was manifested by a slower androgen-dependent nuclear transfer of EGFP-AR and a homogeneous nuclear localization. A delayed advent of nuclear clusters was observed in presence of CPA. We conclude that the PNT1A cell line is a better model than the DU-145 cell line to analyze the trafficking of AR and the association of AR on the nuclear matrix, as well as to observe the action of antiandrogens on these critical steps in prostate cells.

Abstract
The skeletal system is a common target of glucocorticoids. Structural and functional impairment of skeletal system is a relevant cause of morbidity and disability in patients with Cushing's syndrome. Thirty-six patients long-term (3.9 +/- 0.5 yrs) cured from Cushing's disease (CD), 26 with adulthood-onset CD (AOCD) and 10 with childhood-onset CD (COCD) and 2 groups of controls, 24 age- and sex-matched patients with nonfunctioning pituitary adenomas (NFA) and 36 age- and sex-matched healthy subjects (HS), entered this open transversal controlled study to evaluate the prevalence of spine abnormalities and damage by standard radiography in subjects with a history of Cushing's syndrome. Symptoms and signs of backache were present in 86.1% CD patients (100% COCD and 80.8% AOCD), in 30.5% HS (chi2 = 20.6, p < 0.0001) and 37.5% NFA patients (chi2 = 13.2, p < 0.0001). The prevalence of trabecular bone rarefaction (chi2 = 6.5, p < 0.01 and chi2 = 4.5, p < 0.05), vertebral collapse (chi2 = 10.7, p < 0.01 and chi2 = 7.0, p < 0.01) and scoliosis (chi2 = 10.9, p < 0.01 and chi2 = 11.1, p < 0.01) resulted significantly increased in CD patients as compared both to HS and NFA patients. In CD patients, the number of collapsed vertebral bodies was significantly correlated to age of disease onset (r = -0.63, p < 0.0001), disease duration (r = 0.33, p < 0.05) and urinary free cortisol levels at disease diagnosis (r = 0.72, p < 0.0001). The prevalence of cortical bone sclerosis was significantly increased in AOCD than in HS (chi2 = 6.5, p < 0.01) and COCD (chi2 = 7.7, p < 0.01) whereas that of trabecular bone rarefaction was significantly higher in COCD patients than in HS (chi2 = 18.3, p < 0.0001), NFA (chi2 = 14.2, p < 0.0001) and AOCD patients (chi2 = 9.1, p < 0.01). Patients cured from CD have increased prevalence of spine damage, mostly when the disease developed before the completion of skeletal growth. Therefore, a periodical radiological follow-up of the skeleton and a specific treatment for the bone damage should be included in the management of patients with Cushing's syndrome.

Abstract
Both endogenous and exogenous factors are involved in regulation of endocrine secretions. Among the exogenous ones, light plays an important role both in animals and in humans. Pineal gland mediates light action on the endocrine system, by means of variations of melatonin (MT) secretion. Here we discuss about the influence of abnormal light-dark cycles and in particular of blindness on pineal and pituitary secretions and on those of correlated glands. MT secretion is usually inhibited by light: thus it reaches the highest levels at night. Exposure to short or long photoperiod causes variations in circadian or infradian MT rhythmicity. Blind patients can show higher daytime levels with a phase-advanced or phase-delayed circadian rhythm. Lack of light stimulus affects cortisol rhythm shifting the zenith of secretion and inducing a free-running rhythm. Blindness can abolish nocturnal growth hormone (GH) peak and impair the GH response to some stimuli; moreover it impairs the growth of affected patients. Light stimulus influences favorably gonadal function both in animals and in man. In animals, sexual activity and gonadal function decline during the seasons with reduced luminosity. A similar finding has been described in women living in a region with a strong seasonal contrast in luminosity. Blindness can impair luteinizing hormone, follicle-stimulating hormone, prolactin and testosterone secretion in prepubertal boys causing pubertal delay or more severe hypogonadism; it can affect pubertal development and fertility in women. Light can influence thyroid function in animals. Lack of light stimulus in blind man seems to cause different effects on thyroid function before and after puberty. Increase of free thyroid hormone levels has been found in prepubertal but not in adult blind patients, probably due to a resetting of the threshold for thyrotropin feedback suppression after puberty in these patients.

Abstract
We developed a new stable prostatic cell line expressing the human androgen receptor (AR) and the AR-responsive reporter gene to generate a powerful tool for investigating androgen action and for rapid screening of agonists and antagonists. The AR-deficient PC-3 cells were stably transfected with pSG(5)-puro-hAR and pMMTV-neo-Luc. After selection with puromycin and neomycin, one highly inducible clone was isolated and named PALM, for PC-3-Androgen receptor-Luciferase-MMTV. The expression of hAR was confirmed by western blot and steroid-binding assays on the whole cells. The transcriptional activity of the clone was measured after incubation of cells with increasing concentrations of synthetic R1881 or natural androgens (DHT and testosterone). The three agonists had the same maximal activity at 0.1 microM and the fold induction was equal to 20. The agonist and antagonist activities of the steroidal antiandrogens (cyproterone acetate and RU2956) and the non-steroidal antiandrogens (nilutamide, bicalutamide, inocoterone and hydroxyflutamide) measured with the PALM cells were in good correlation with the results obtained with transiently transfected cells. The selectivity in steroid transactivation was demonstrated with estradiol, progesterone, cortisol, dexamethasone and aldosterone. Spironolactone and RU486 showed partial agonist and antagonist activities, whereas R5020 presented only a partial antagonist activity. We here demonstrate that this stable transfectant provides an accurate tool for studying wild-type human AR activation and its regulation by androgens and antiandrogens in a human prostatic epithelial cell, which is routinely available and remains androgen-responsive in vitro.

Abstract
Prostate cancer is an androgen-dependent tumor which presents an androgen-independent regrowth after clinical regression in response to antiandrogen treatment. Four hypotheses have been developed to understand how androgen signal transduction pathway mediate androgen-independent tumor progression: over expression of the wild-type androgen-receptor gene, androgen-receptor gene mutation, excessive recruitment of transcriptional co-activator ARA-70 and a cross-talk between the androgen-receptor and the growth factor receptor pathways. In this work, C. Sawyers's group elegantly demonstrates, in LAPC-4 androgen-independent prostate cancer sublines, that forced hyperexpression of HER-2/Neu receptor tyrosine kinase allowed androgen-independent growth, that HER-2/Neu activated the androgen-receptor pathway in the absence of androgens and synergized with low levels of androgen to superactivate the pathway. These important data could have therapeutic implications for the management of androgen-independent prostate cancer.

Abstract
PURPOSE We verified the prevalence of serum antisperm antibodies at diagnosis in a large group of cryptorchid boys, and determined whether it may be influenced by orchiopexy. MATERIALS AND METHODS We prospectively evaluated serum antisperm antibodies in 186 and 23 boys 0.67 to 14.25 years old with unilateral and bilateral cryptorchidism, respectively, before, and 3, 12 and 24 months after surgery. At diagnosis Tanner stage was 1 and 2 or 3 in 188 and 21 cases, respectively. During the 2-year followup 23 boys entered puberty. A total of 111 normal prepubertal (Tanner stage 1) and 54 pubertal (Tanner stage 2 or 3) boys served as controls. Antisperm antibodies were detected using the tray agglutination and indirect immunobead tests. RESULTS At diagnosis 29 cryptorchid boys (13.8%) were antisperm antibody positive, including 21 of the 188 prepubertal (11.1%) and 8 of the 21 pubertal (38%) boys (significantly different, chi-square test p <0.001). In 27 cases the tray agglutination test was positive with titers between 1:16 and 1:512, in 18 the indirect immunobead test was positive for IgG with titers between 1:10 and 1:100, and in 16 both tests were positive. There was no statistical difference when antisperm antibody results were analyzed for unilateral and bilateral cryptorchidism or testis location. All normal boys were antisperm antibody negative. During the 2-year followup antisperm antibodies appeared in 1 previously negative case, and the antibody titer increased to 128 to 512 in the tray agglutination and to 1:100 in the indirect immunobead tests in 4 positive cases. In all of these cases pubertal changes were also observed. CONCLUSIONS Our study indicates that cryptorchidism may elicit an autoimmune response against sperm antigen in childhood independent of testis location and orchiopexy. Moreover, patients of pubertal age appear to be at higher risk for antisperm antibody development.

Abstract
Aim of this study was to plot height, weight and height velocity values of primary school civic population of Portici and Ercolano, Campania towns, on Tanner's charts in order to verify the overlapping of percentile distribution. On May 1994 height and weight were measured in 3504 children (1735 boys and 1769 girls, aged 5.4-16.1 years, mean age = 8.6 years) from the 1st, 2nd and 5th year of primary schools in Portici and Ercolano. One year later, on May 1995, we remeasured and reweighed 1583 (781 boys and 802 girls, aged 6.4-14.2 years, mean age = 9.6 years) out of total children and we calculated height velocity (HV). The height and weight profiles of our population sample show that children in Portici and Ercolano are taller and fatter than those measured by Tanner and Whitehouse 25-30 years ago. The calculation of body mass index (BMI) confirmed that 30% of total children were obese. Furthermore, the evaluation of one-year HV revealed a clear improvement of linear growth. Our data suggest that Tanner and Whitehouse charts should be updated, and it should be useful to elaborate also height, weight and HV standards derived from present-day population.

Abstract
At present, there is a growing body of evidence implicating growth hormone (GH) and/or insulin-like growth factor-I (IGF-I) in the intricate cascade of events connected with the regulation of heart development and hypertrophy. In addition, advanced clinical manifestations of abnormal GH levels almost always include impaired cardiac function, which may reduce life expectancy. This finding is related both to a primary impairment of heart structure and function and to metabolic changes such as hyperlipidaemia, increased body fat and premature atherosclerosis. Acromegalic cardiomyopathy is better correlated with disease duration than with GH or IGF-I levels. Myocardial hypertrophy with interstitial fibrosis, lymphomononuclear infiltration and areas of monocyte necrosis often result in increased right and left ventricular mass concentric hypertrophy. Conversely, patients with childhood or adult-onset GH deficiency (GHD) have a reduced left ventricular mass (LVM) and ejection fraction (EF) and the indices of left ventricular systolic function remained markedly depressed during exercise. Cardiac function is reported to improve during octreotide and GH replacement treatment in acromegaly and GHD, respectively. The evidence that GH can increase cardiac mass suggests its use in the treatment of idiopathic dilated cardiomyopathy. In a recent study on such patients, the administration of recombinant GH (rGH) was demonstrated to increase myocardial mass and reduce the size of the left ventricular chamber, resulting in improved haemodynamics, myocardial energy metabolism and clinical status.
