RESUMO
OBJECTIVE: Despite having normal thyroid-stimulating hormone levels, many hypothyroid patients are dissatisfied with the treatment. The primary aim of this study was to evaluate the effect of twice-daily, combination therapy with levothyroxine (LT4) and liothyronine (LT3), at doses adapted according to TSH-level, on peripheral tissues as reflected by sex hormone binding globulin (SHBG) levels in totally thyroidectomized patients. Changes in other tissue markers and quality of life considering DIO2-rs225014 and MCT10-rs17606253 genetic variants were also assessed. DESIGN: Double-blind, randomized, placebo-controlled. METHODS: One hundred and forty-one subjects were randomized to LT4 + LT3 group (LT4 + LT3 in the morning and LT3 in the evening; n = 70) or placebo group (LT4 in the morning and placebo in the evening; n = 71). Pituitary-thyroid axis compensation was assessed after 6, 12, and 24 weeks. Clinical parameters, quality of life, and tissue markers (sex hormone binding globulin, serum lipids, bone markers) were evaluated at 12 and 24 weeks. DIO2 and MCT10 single nucleotide polymorphisms were genotyped. RESULTS: The LT4 + LT3 group was treated with mean daily LT3 doses of 5.00â µg, with a mean daily LT4 reduction of 15â µg. After 6 months of treatment, neither SHBG and other tissue markers nor quality of life differed significantly between groups. Combination treatment required greater dose adjustments than placebo (25% vs 54%, P < .001), due to thyroid-stimulating hormone reduction, without hyperthyroidism signs or symptoms. At the end of treatment, the LT4 + placebo group had significantly lower fT3/fT4 compared to the LT4 + LT3 group (0.26 ± 0.05 vs 0.32 ± 0.08, P < .001). No preference for combination therapy was found. Genetic variants did not influence any outcomes. CONCLUSIONS: Six months of combination therapy with twice-daily LT3 dose adapted according to TSH-level do not significantly change peripheral tissue response or quality of life, despite an increase in the fT3/fT4 ratio.

PURPOSE: The utility of repeating ultrasound-guided fine-needle aspiration (US-FNAB) in the follow-up of benign (THY2) thyroid nodules is still debated. The aim of this study was to retrospectively investigate the diagnostic value of re-biopsy of thyroid nodules following an initially benign result. METHODS: We retrospectively analyzed US-FNABs performed at the Unit of Endocrinology of Modena from 2006 to 2009. The firstly benign cytological result was compared with the cytological results of subsequent US-FNABs (2nd and/or 3rd) executed on the same nodule. RESULTS: Among 10449 US-FNABs, 6270 (60%) received a THY2 cytological categorization. Of them, 278 (4.43%) underwent a subsequent US-FNAB: 86.7% maintained the same cytology, 32 (11.5%) changed to THY3 (indeterminate) and 5 (1.8%) to THY4 (suspicious of malignancy). Among the 24 nodules addressed to surgery, 9 (37%) were histologically malignant, with an overall miss rate of 3.2%. Male patients had higher risk of discordant results at subsequent US-FNAB (p = 0.005, OR:3.59, 95%CI:1.453-7.769) while dimensional increase above 5 mm was predictive of concordant benign cytology (p = 0.036, OR:0.249, 95%CI:0.068-0.915). Age, suspicious US characteristics, and distance between US-FNABs resulted not predictive. CONCLUSIONS: Re-biopsy of benign nodules confirmed the benign nature in most cases. In case of discordant cytology, relocation in indeterminate category was the most common. The histological diagnosis of cancer occurred in one quarter of nodules surgically removed, with a low overall clinically significant miss rate. Thus, a small percentage of false negatives exists; males and subjects with US suspicious nodules should be carefully followed-up, considering case by case re-biopsy possibility.

OBJECTIVE: The objectives of this study were to describe the trajectories of bone mineral density (BMD) and trabecular bone score (TBS) changes throughout pre-menopause (reproductive phase and menopausal transition) and post-menopause (early and late menopause) in women with HIV (WWH) undergoing different antiretroviral therapies (ARTs) and explore the risk factors associated with those changes. METHODS: This was an observational longitudinal retrospective study in WWH with a minimum of two DEXA evaluations comprising BMD and TBS measurements, both in the pre-menopausal and post-menopausal periods. Menopause was determined according to the STRAW+10 criteria, comprising four periods: the reproductive period, menopausal transition, and early- and late-menopausal periods. Mixed-effects models were fitted to estimate the trajectories of the two outcomes (BMD and TBS) over time. Annualized lumbar BMD and TBS absolute and percentage changes were calculated in each STRAW+10 time window. A backward elimination procedure was applied to obtain the final model, including the predictors that affected the trajectories of BMD or TBS over time. RESULTS: A total of 202 WWH, all Caucasian, were included. In detail, 1954 BMD and 195 TBS data were analyzed. The median number of DEXA evaluations per woman was 10 (IQR: 7, 12). The median observation periods per patient were 12.0 years (IQR = 8.9-14.4) for BMD and 6.0 years (IQR: 4.3, 7.9) for TBS. The prevalence of osteopenia (63% vs. 76%; p < 0.001) and osteoporosis (16% vs. 36%; p < 0.001) increased significantly between the pre-menopausal and post-menopausal periods. Both BMD (1.03 (±0.14) vs. 0.92 (±0.12) g/cm2; p < 0.001) and TBS (1.41 (IQR: 1.35, 1.45) vs. 1.32 (IQR: 1.28, 1.39); p < 0.001) decreased significantly between the two periods. The trend in BMD decreased across the four STRAW+10 periods, with a slight attenuation only in the late-menopausal period when compared with the other intervals. The TBS slope did not significantly change throughout menopause. The delta mean values of TBS in WWH were lower between the menopausal transition and reproductive period compared with the difference between menopause and menopausal transition. CONCLUSIONS: Both BMD and TBS significantly decreased over time. The slope of the change in BMD and TBS significantly decreased in the menopausal transition, suggesting that this period should be considered by clinicians as a key time during which to assess bone health and modifiable risk factors in WWH.

Objective: The serum calcium (Ca)-to-phosphorus (P) ratio has been proposed to identify patients with primary hyperparathyroidism and chronic hypoparathyroidism (HPT), but it has never been tested in pseudohypoparathyroidism (PHP). The aim of this study was to test the performance of Ca/P ratio in PHP diagnosis compared with that in healthy subjects and patients with HPT for differential diagnosis. Design: A retrospective, cross-sectional, and observational study was carried out. Methods: Serum Ca, P, creatinine, parathyroid hormone (PTH), and albumin were collected. Ca and P were expressed in mmol/L. Ca/P diagnostic performance was evaluated by receiver operating characteristic curve, sensitivity, specificity, and accuracy. Results: A total of 60 patients with PHP, 60 patients with HPT, and 120 controls were enrolled. The Ca/P ratio was lower in patients with PHP and HPT than that in controls (p < 0.0001). The cutoff of 1.78 (2.32 if Ca and P measured in mg/dL) for Ca/P ratio could identify patients with PHP and HPT among the entire cohort (sensitivity and specificity of 76%). No valid cutoff of Ca/P was found to distinguish patients with PHP from patients with HPT; in this case, PTH above 53.0 ng/dL identified patients with PHP (sensitivity and specificity of 100%). The index (Ca/P × PTH) above 116 ng/L recognized patients with PHP from controls (sensitivity of 84.7% and specificity of 87.4%), whereas (Ca/P × PTH) below 34 ng/L recognized patients with HPT from controls (sensitivity of 88.9% and specificity of 90.8%). Conclusions: The Ca/P ratio below 1.78 (2.32 CU) is highly accurate to identify patients with PHP and HPT, although it is not reliable to differentiate these two conditions. The index (Ca/P × PTH) is excellent to specifically recognize PHP or HPT from healthy subjects.

Hypogonadism is a frequent finding among men living with HIV (MLWH) and it seems to occur earlier in comparison with the general male population. Although the prevalence of hypogonadism in MLWH has significantly lowered thanks to advancements in medical management, it remains high if compared with age-matched HIV-uninfected men, ranging from 13% to 40% in the age group of 20-60 years. Signs and symptoms of low serum testosterone (T) in MLWH are cause of concern since they are non-specific, of mild-to-moderate degree, and often overlapping with those of infection per se. For these reasons, hypogonadism can be underestimated in the absence of targeted laboratory blood examinations. With regard to the etiological factors involved in the T decrease, emerging evidence has suggested the functional nature of hypogonadism in MLWH, pointing out the mutual relationship between sex steroids, health status, comorbidities, and HIV-related factors. In agreement with this hypothesis, a therapeutic approach aiming at improving or reversing concomitant diseases through lifestyle changes (e.g. physical activity) rather than pharmacological T treatment should be theoretically considered. However, considering both patient's barriers to lifestyle changes to be maintained overtime and the lack of evidence-based data on the efficacy of lifestyle changes in normalizing serum T in MLWH, T therapy remains an option when other non-pharmacological interventions are ineffective as well as for all other functional forms of hypogonadism. From this perspective, the traditional therapeutic management of male hypogonadism in MLWH, especially the role of T supplementation, should be revised in the light of the probable functional nature of hypogonadism by considering a good balance between benefits and harmful. This narrative review presents an overview of current knowledge on hypogonadism in MLWH, deepening the factors driving and taking part in T decrease, providing advice for the clinical approach, and underlining the importance of individualized treatment aiming at optimizing non-gonadal comorbidities and thus avoiding over-, or even unnecessary, treatment with T.

(1) Background: While females start their gynecological examinations during puberty, only few men decide to be visited by urologists in their youth. Given the participation in the EcoFoodFertility research project, our department had the opportunity to screen young males that were supposedly healthy. (2) Results: from January 2019 to July 2020, we evaluated 157 patients with sperm, blood analysis, and uroandrological examinations. The inclusion criteria were age 18-40 and absence of previous urological disease (urology-naïve). The primary endpoint of the study was to record uroandrological diseases that are occasionally discovered during examination in asymptomatic young men. The average age was 26.9 years (range 18-40); average testicular volume was 15.7 mL (range 12-22 mL); and 45.2% reported abnormal semen analysis: 62 cases of teratozoospermia, 27 asthenozoospermia, 18 oligozoospermia, and 2 azoospermia were discovered respectively; 4/157 patients were diagnosed with hypogonadism; 2 cases with suspicious testicular mass resulted in testicular cancer; and 31 suspected varicoceles and 8 patients with mild sexual dysfunctions were managed. (3) Conclusions: an uroandrological evaluation of young asymptomatic males allowed for the prompt diagnosis of different urological conditions, including cancerous ones, in our series. Despite being debatable, combining urological counselling with physical examination, semen analysis, and a laboratory profile could be useful and cost-effective in order to ameliorate male health.
RESUMO
Summary: A 44-year-old athletic man presented in 2009 with severe low back pain. Dual-energy x-ray absorptiometry revealed severe osteoporosis; serum testosterone was 189 ng/dL while serum estradiol (E2) measured by liquid chromatography/mass spectrometry was 8 pg/mL. DNA was extracted and sequenced from a blood sample from the patient since his maternal first cousin also had low bone mass and both patients were screened for aromatase dysfunction by PCR analysis for the CYP19A1 gene, which encodes aromatase. No known pathologic mutations were observed in the coding exons, but novel single nucleotide polymorphisms were detected both in the proband and in his cousin. Treatment with topical testosterone started in August 2010. Over the next 8 years, testosterone dosage was varied and switched from topical gel to injections and maintained on depo-injections of testosterone at about 60 mg once per week. Re-examination in March 2012 included a brain MRI to exclude pituitary lesions; hyperparathyroidism was ruled out (normal serum parathyroid hormone, calcium, and calcium to phosphorous ratio) and celiac disease was excluded (negative transglutaminase antibodies). Follow-up in October 2018 showed improved bone mineral density of the lumbar spine by 29% and of the left femoral hip by 15% compared to baseline measurements. This reveals the importance of measuring serum E2 for making the correct diagnosis, as well as for monitoring a therapeutic effect. Herein, we propose treatment of male osteoporosis where serum E2 levels are below about 20 pg/mL with testosterone to reverse osteoporosis. Learning points: Estrogen deficiency in the diagnosis of male idiopathic osteoporosis. Importance of serum estradiol in male osteoporosis. Role of polymorphisms in aromatase gene on bone health. Reversal of osteoporosis. Tailored testosterone treatment for bone health.
RESUMO
BACKGROUND AND AIM: Notwithstanding the improvement in therapies, patients affected by thalassemia major (TM) and intermedia (TI) are still at high risk of cardiac complications. This study aimed at evaluating the incidence and predictive factors for developing cardiac events in adult ß-TM and TI patients. POPULATION AND METHODS: Data on diagnosis and clinical history were collected retrospectively; prospective data on new-onset cardiac failure and arrhythmias, echocardiographic parameters, biochemical variables including non-transferrin-bound iron (NTBI) and labile plasma iron (LPI), magnetic resonance imaging (MRI) T2* measurement of hepatic and cardiac iron deposits, and iron chelation therapy were recorded during a 6-year follow-up. RESULTS: Thirty-seven patients, 29 TM and 8 TI, were included. At baseline, 8 TM patients and 1 TI patient had previously experienced a cardiac event (mainly heart failure). All patients were on chelation therapy and only 3 TM patients had mild-to-severe cardiac siderosis. During follow-up, 11 patients (29.7%) experienced a new cardiac event. The occurrence of cardiac events was correlated to high LPI levels (OR 12.0, 95% CI 1.56-92.3, p .017), low mean pre-transfusion haemoglobin (OR 0.21, 95% C.I. 0.051-0.761, p .21) and echocardiographic parameters suggestive of myocardial hypertrophy. Multivariate analysis disclosed high LPI and left ventricle mass index (LVMI) as independent variables significantly associated with cardiac events. Cardiac iron deposits measured by MRI T2* failed to predict cardiac events. CONCLUSION: LPI, Hb levels and echocardiographic parameters assessing cardiac remodelling are associated with cardiac events in adult TM and TI patients. LPI might represent both a prognostic marker and a potential target for novel treatment strategies. Further studies are warranted to confirm our findings on larger populations.

BACKGROUND: Sexual dysfunctions, particularly erectile dysfunction, are common in men living with HIV, whose organic and psychological components remain to be clarified. The aim of the study is to investigate the impact of risk factors of sexual dysfunctions, including organic, relational, and psychological determinants of erectile function, in men living with HIV younger than 50 years old. METHODS: A cross-sectional, observational study was conducted in men living with HIV < 50 years. The questionnaire International Index of Erectile Function-15 was used to assess the prevalence and degree of erectile dysfunction. The structured interview of erectile dysfunction was used to explore the organic (Scale 1), relational (Scale 2), and psychological (Scale 3) components of erectile dysfunction. Total testosterone, estradiol, and dihydrotestosterone were measured by liquid chromatography-tandem-mass spectrometry; free testosterone was calculated by the Vermeulen equation. RESULTS: A total of 313 consecutive men living with HIV were prospectively enrolled (median age 47.0 years; median HIV-infection duration 16.2 years). 187 patients (59.7%) had erectile dysfunction, with a higher prevalence of non-heterosexual (138 out of 187, 73.8%) than heterosexual patients (p = 0.003). Patients with erectile dysfunction showed a worse score of structured interview of erectile dysfunction scale 3 compared to patients without erectile dysfunction (p = 0.025); the International Index of Erectile Function-15 was inversely related to structured interview of erectile dysfunction scale 3 (p = 0.042). No difference was found for sex steroids (total testosterone, estradiol, free testosterone, and dihydrotestosterone) between men living with HIV with and without erectile dysfunction. In the multivariate analysis sexual orientation, and lack of stable relationships were major determinants for erectile dysfunction. Only 35 of 187 patients with erectile dysfunction (18.7%) reported the use of erectile dysfunction medications. CONCLUSIONS: Within the multidimensional network of erectile dysfunction in men living with HIV, the psychological component is predominant, highlighting the contribution of peculiar factors related to HIV distress (e.g., fear of virus transmission, stigma) rather than gonadal status and other classical risk factors. In contrast to the high prevalence, only a few patients reported the use of erectile dysfunction medications suggesting a general under-management of such issues.

INTRODUCTION: Although a trustworthy connection between doctor and patient is crucial in clinical practice, it could be hindered by different cultural and linguistic backgrounds. Moreover, an effective doctor-patient interaction could be even more challenging in andrological fields, in which psychological and social components are predominant. AIM: To analyse the doctor-patient relationship in the andrological field, applying both qualitative and quantitative analyses. METHODS: monocentric, cross-sectional, observational study was performed between May and December 2018. During the study, all patients aged >18 years attending the Modena Andrology Unit for couple infertility or erectile dysfunction were enrolled and the doctor-patients interaction recorded. Patients were divided into two groups depending on their medical seeking and were further divided between native and non-native speakers of Italian. All patients underwent a routine andrological examination. Every first medical consultation was audio-recorded and transcribed using "ELAN" software for socio-linguistic analysis. Transcriptions underwent qualitative analysis through conversation analysis. Then, quantitative analyses were performed, and interaction parameters underwent correlation analyses. RESULTS: Twenty-five patients were enrolled. The analysis of the andrological interview allowed to recognise five consecutive phases, following a semi-standardized pattern. Patients without linguistic barriers and with infertility problems showed more autonomous contribution during the consultation. No difference arose in the sexual dysfunctions group. Doctor's explanations were frequent, but when linguistic barrier was present or Italian patients seemed less talkative, explanations were shorter, and doctors tried to use other conversational mechanisms to promote understanding. Patient's variables were significantly lower compared to the doctor, considering the number of turns (p = 0.025) and their minimum (p = 0.032), maximum (p < 0.001), and average durations (p < 0.001). Only patient's latency was significantly higher than the doctor's (p = 0.001). CONCLUSION: This is the first attempt to analyse the doctor-patient relationship in andrology using authentic audio-recorded consultations. The results confirmed that a patient-centred communication must be applied also in andrological consultations. However, the topics discussed may require more "medical formulation" to be acceptable to the participants in this context.

BACKGROUND: Data about classification of hypogonadism and estrogen deficiency in male people living with HIV (PLWH) are scanty. AIM: To investigate the prevalence and characterization of biochemical hypogonadism and relative estrogen deficiency in male PLWH aged < 50 comparing liquid chromatography-tandem mass spectrometry (LC-MS/MS) with chemiluminescent immunoassay (CI), and combining gonadotropin, sex hormone-binding globulin (SHBG) and serum estradiol (E2) measurements. METHODS: Prospective, cross-sectional, observational study. Serum total testosterone (TT), E2, gonadotropins, SHBG were measured by CI. TT and E2 were also assessed by LC-MS/MS. Free testosterone (cFT) was calculated by Vermeulen equation. RESULTS: A total of 316 PLWH (45.3 ± 5.3 years) were enrolled. TT and cFT by LC-MS/MS were lower compared to CI (p < 0.0001). The prevalence of biochemical hypogonadism was higher with LC-MS/MS than CI, both for TT (5.1% vs 3.2%, p < 0.0001) or cFT (9.5% vs 7%, p < 0.0001). The prevalence of hypogonadism (overt + compensated) was 17.1% for cFT using LC-MS/MS. Secondary form of hypogonadism was more prevalent than primary. The prevalence of relative estrogen deficiency was of 30.0% among hypogonadal patients and 15.5% among eugonadal. CONCLUSIONS: The prevalence of male hypogonadism results underestimated by CI compared to LC-MS/MS in PLWH, both for TT and cFT. SHBG and gonadotropins are essential for detecting T deficiency.

BACKGROUND: Hypogonadism is a common comorbidity in human immunodeficiency virus (HIV)-infected men, although the real prevalence is difficult to be estimated. Moreover, in HIV settings, the efficacy of exogenous testosterone (Te) administration at improving body composition remains unclear. AIM OF THE STUDY: This review has a double aim. First, to estimate the prevalence of pituitary-testis axis abnormality in HIV-infected patients compared to uninfected subjects. Second, to evaluate the effect of androgen administration on body composition in HIV-infected men. MATERIALS AND METHODS: A systematic review of the literature and meta-analysis was carried out. Two separated literature searches were performed, the first to evaluate the prevalence of Te deficiency in HIV-infected men and the second one to evaluate effects of androgen administration on body composition. RESULTS: The overall prevalence of Te deficiency in HIV-infected men was calculated from 41 studies, showing a 26% prevalence, which was even higher when free T (fT) levels, more than total T, were considered. Indeed, TT serum levels were similar between HIV patients and controls, although higher SHBG and lower fT were detected in HIV populations. When HIV-infected men were treated with exogenous Te, a significant increase in body weight, lean body mass and fat free mass was detected. CONCLUSION: The systematic review confirms the high prevalence of Te deficiency in HIV-infected men, particularly when fT has been considered. Moreover, chronic androgen supplementation improves body composition, affecting the lean mass compartment. However, considering the general frailty of HIV patients, a tailored indication for Te therapy should be advocated.

BACKGROUND: Temozolomide (TMZ) is safe and effective in the treatment of aggressive pituitary adenomas (PAs). However, the optimal duration of TMZ therapy is still unknown. Moreover, data about administration of TMZ in elderly (≥65 years) people to treat aggressive PAs are scarce. We report the case of the oldest female patient undergoing the longest TMZ protocol described so far to treat an aggressive, initially silent corticotroph PA. CASE REPORT: The patient initially underwent partial surgical removal of the PA. Subsequent treatment with cabergoline was applied, but it was unsuccessful in controlling the growth of the residual tumor. Pasireotide and external radiation also showed to be ineffective; therefore, treatment with TMZ was started at the standard dose of 200 mg/m2/day for 5 days every 4 weeks for a total of 47 cycles. At the time of treatment's beginning, the patient was 83 years old. Radiological follow-up documented a progressive, remarkable reduction of the adenoma and the last imaging, after 39 cycles of TMZ, showed an intrasellar lesion with large areas of cystic degeneration. The patient also developed adrenal deficiency managed with glucocorticoid replacement. No major side effects were observed throughout the treatment, with exception of nausea, well controlled with anti-emetic medication. TMZ therapy was discontinued after 47 cycles; hormonal and imaging follow-up investigations documented sustained functional and dimensional response. CONCLUSIONS: Our case supports the long-term use of TMZ, confirming its safety and efficacy also for elderly patients.
RESUMO
Sexual issues tend to go unaddressed in human immunodeficiency virus (HIV) management, although overt sexual dysfunctions are more prevalent in people living with HIV than uninfected people. Erectile dysfunction is the most frequent sexual problem, with a prevalence of 30-50% even in men <40 years of age, but other issues such as loss of libido and ejaculatory disorders should not be overlooked. Peculiar factors related to HIV infection (e.g., fear of virus transmission, changes in body image, HIV-related comorbidities, HIV distress and stigma), alongside classical factors non-related to HIV, should be considered when approaching sexual problems in HIV patients. For this reason, the diagnostic and therapeutic workout of sexual dysfunction in the context of HIV requires a multidisciplinary approach, involving specialists in both infectious diseases and sexual medicine. This narrative review presents an overview of current knowledge on sexual dysfunction in HIV men, deepening the factors driving and taking part in these issues, providing advice for the clinical approach, and underlining the importance of caring for sexual health to improve the quality of life of HIV patients.
RESUMO
PURPOSE: This study aimed to evaluate the real-life use of BRAF-V600E mutation analysis in washout liquid from thyroid nodule fine needle aspiration (FNA), and the consequences of genetic result on clinical decision-making. METHODS: We retrospectively considered subjects tested for BRAF-V600E among those attending the Endocrinology Unit of Modena for FNA between 2014 and 2018. Washing fluid was collected together with cytological sample and stored at -20 °C. If the clinician deemed it necessary, the sample was thawed, DNA extracted, and genetic test performed by high-resolution melting technique. We collected data on cytology according to the Italian Consensus for the cytological classification of thyroid nodules, type of surgery (when performed), histology, and adverse events. RESULTS: Out of 7112 subjects submitted to FNA, BRAF analysis was requested for 683 (9.6%). Overall, 896 nodules were analyzed: 74% were indeterminate at cytology, mainly TIR3A (low risk). Twenty-two nodules were mutant (BRAF+). Only 2% of indeterminate, mainly TIR3B, were BRAF+. Based on final histological diagnosis, BRAF test had high specificity (100%) but poor sensitivity (21%), also in indeterminate nodules. Mutant subjects underwent more extensive surgery compared to wild type (p = 0.000), with frequent prophylactic central lymph node dissection. One third had local metastases. Higher prevalence of hypoparathyroidism was found in BRAF+ compared to wild type (p = 0.018). CONCLUSIONS: The analysis of BRAF-V600E outside of gene panels has low sensitivity, especially in indeterminate nodules, and a positive result could lead to more extensive surgery with greater risk of hypoparathyroidism and questionable clinical utility.

Over the past two decades several large cohort studies have been performed to disclose the changes of sex hormone in elderly and their clinical significance. Beyond the decline of total testosterone, aging is accompanied by a sex hormone binding globulin (SHBG) increase, a steeper free testosterone decline, while gonadotropins may be increased or inappropriately normal, with important contribution of comorbidities (e.g., obesity) to these changes. Actually, it has become firm the concept that the biochemical finding of testosterone deficiency alone is not sufficient for diagnosing hypogonadism in older men. The definition of late-onset hypogonadism (LOH) includes low serum testosterone levels coupled with signs and symptoms related to hypogonadism. Indeed, the combination of multiple factors all contributing to the testosterone decline, with other concurrent comorbidities further overlapping, makes the clinical correlates of LOH highly heterogeneous. For all these reasons both the diagnosis and the therapeutic management of LOH, especially the decision about starting testosterone replacement treatment, remain challenging.

CONTEXT: Although sexuality influences well-being and quality of life (QoL), studies on sexual dysfunction (SD) in adult growth hormone deficiency (AGHD) patients are lacking. OBJECTIVE: To investigate the prevalence of SD in AGHD patients grouped according to recombinant human growth hormone (r-hGH) therapy. DESIGN: Prospective, cross-over, 24 months, monocentric study. SETTING: Real-life clinical setting in a tertiary, endocrinological center. PATIENTS: 83 AGHD patients (31 women, 52 men, mean age 56.3 ± 14.7 years) were enrolled according to stringent criteria. INTERVENTIONS: Patients already on long-term r-hGH therapy (Group 1, nâ =â 32) vs untreated (Group 2, nâ =â 51). MAIN OUTCOME MEASURES: Serum hormones, QoL Satisfaction in Hypopituitarism (QLS-H) and QoL Assessment of GHD in Adults (QoL-AGHDA) questionnaires for QoL, Index for Erectile Function-15 (IIEF-15) in men, and Female Sexual Function Index (FSFI) in women for SD. RESULTS: The overall prevalence of SD was 71.2% (60% men, 89% women). All IIEF-15 scores were lower (Pâ =â 0.001) and erectile dysfunction was more prevalent in Group 2 (75%) than Group 1 (35%). IGF-1 was correlated to scores of all IIEF-15 domains, particularly with that of erectile function (EF) (R2=0.123, Pâ =â 0.019). EF domain score correlated with QLS-H (Pâ <â 0.005) and QoL-AGHDA (Pâ =â 0.001). Despite the high prevalence of female SD also in untreated AGHD women, FSFI scores did not correlate with IGF-1 levels and QoL scores. CONCLUSIONS: SD is highly prevalent in AGHD patients, especially in those untreated. SD represents an overlooked and neglected issue in AGHD, regardless the contribution of sexual life on QoL. The evaluation of sexual function should be integrated in the global assessment of AGHD patients.
RESUMO
Background: Robotic adrenalectomy offers several clinical benefits if compared with laparoscopic adrenalectomy; however, its superiority is still under debate. The aim of this study was the investigation of differences between the two techniques, and a comparison when approaching right or left side adrenal lesions was further conducted. Materials and Methods: All patients undergoing laparoscopic and robotic unilateral adrenalectomy at our institution from January 2006 to December 2019 were collected and retrospectively analyzed. Statistical analysis was conducted; differences between the two cohorts were reported. Results: A total of 160 cases were included (84 patients in laparoscopic adrenalectomy-group [LA-g] 76 cases in robotic adrenalectomy-group [RA-g]). The groups were homogeneous for demographic data. No intraoperative complications were reported; mean amount of intraoperative blood loss was comparable. No cases of conversion to open surgery were required. RA-g presented a longer operative time than LA-g for right adrenalectomy (P = .05), no differences were noted for left side (P = .187). Overall morbidity was 21% for LA-g and 10.5% for RA-g (P = .087), with an inferior rate of surgical complications for RA-g (P = .024), and for robotic left adrenalectomy than robotic right procedure (P = .03). Length of hospital stay was shorter for RA-g (P = .005). Conclusions: Robotic adrenalectomy presents similar outcomes as laparoscopic approach with some benefits for selected cases. Left adrenal lesions seem to receive greater advantages from robotic technique. Large randomized controlled trials are required to determine the role of robotic adrenal surgery and if the indication can be standardized based on the laterality of adrenal procedure.

SUMMARY: We present the case of a 69-year-old woman who attended the Endocrinology Unit of Modena for a suspicious lymph node in the left cervical compartment discovered during the follow-up of a recurrent gynecological malignancy. At neck ultrasonography, a thyroid goiter was detected, and the further cytological examination was inconclusive for thyroid nodule and compatible with a localization of an adenocarcinoma with papillary architecture for the lymph node. The histological examination after a left neck dissection confirmed the presence of an intracapsular metastasis of a papillary carcinoma immunohistochemically focally positive for thyroid transcription factor 1 and paired box 8 and negative for thyroglobulin. Subsequently, in the suspicion of a thyroid primitiveness, a total thyroidectomy was performed, revealing an intraparenchymal follicular variant of papillary thyroid carcinoma of 2 mm in the right lobe. During the follow-up, the appearance of a suspected cervical metastatic lesion led to another neck dissection, histologically compatible with a papillary carcinoma localization, immunohistochemically focally positive for thyroid transcription factor 1 and paired box 8, and negative for thyroglobulin. The histological revision of surgical specimens suggests the cervical recurrence of the prior gynecological cancer, rather than a thyroid carcinoma metastasis. The case described shows how carefully the cytological, histological and immunoistochemical results must be evaluated in oncological management, considering the whole patient's history. LEARNING POINTS: Neck lymph node metastases occasionally originate from anatomically distant primary sites, such as breast, lung, gastro-intestinal tract, genito-urinary tract and CNS. Histological and immunohistochemical evaluations play an important role to identify the primary malignant site, although in some cases they could mislead the clinicians. A multidisciplinary approach and the evaluation of the whole medical history of the patient are mandatory to guide the diagnostic-therapeutic path and to avoid unnecessary treatments.
RESUMO
OBJECTIVE: Hypogonadism is common in HIV-infected men. The relationship between health status, sex steroids and body composition is poorly known in HIV. The aim was to investigate the association between health status (comorbidities/frailty), body composition, and gonadal function in young-to-middle-aged HIV-infected men. DESIGN: Prospective, cross-sectional, observational study. METHODS: HIV-infected men aged <50 years and ongoing Highly Active Antiretroviral Therapy were enrolled. Serum total testosterone (TT), estradiol (E2), estrone (E1) were measured by liquid chromatography-tandem mass spectrometry, LH and FSH by immunoassay. Free testosterone (cFT) was calculated by Vermeulen equation. Body composition was assessed by dual-energy X-ray absorptiometry and abdominal CT scan. Multimorbidity (MM) and frailty were defined as ≥3 comorbidities and by a 37-item index, respectively. RESULTS: A total of 316 HIV-infected men aged 45.3 ± 5.3 years were enrolled. Body fat parameters were inversely related to cFT and TT, and directly related to E1 and E2/testosterone (TS) ratio. Patients with MM had lower cFT (P < 0.0001) and TT (P = 0.036), and higher E1 (P < 0.0001) and E2/TS ratio (P = 0.002). Frailty was inversely related to cFT (R2 = 0.057, P < 0.0001) and TT (R2 = 0.013, P = 0.043), and directly related to E1 (R2 = 0.171, P < 0.0001), E2 (R2 = 0.041, P = 0.004) and E2/TS ratio (R2 = 0.104, P < 0.0001). CONCLUSIONS: Lower TT and cFT, higher E1, E2/TS ratio and visceral fat were independently associated to poor health status and frailty, being possible hallmarks of unhealthy conditions in adult HIV-infected men. Overall, MM, frailty and body fat mass are strictly associated to each other and to sex steroids, concurring together to functional male hypogonadism in HIV.
