Abstract
OBJECTIVES The goal of evidence-based practice guidelines is to optimize the management of emerging diseases, such as differentiated thyroid cancer (DTC). The aim of this study was to assess therapeutic approaches for DTC in Italy and to see how closely these practices conformed to those recommended in the 2009 American Thyroid Association (ATA) guidelines. METHODS The Italian Thyroid Cancer Observatory was established to collect data prospectively on thyroid cancers consecutively diagnosed in participating centers (uniformly distributed across the nation). Data on the initial treatment of all pathologically confirmed DTC cases present in the database from January 1, 2013 (database creation) to January 31, 2016, were analyzed. RESULTS A total of 1748 patients (77.2% females; median age 48.1 years [range 10-85 years]) were enrolled in the study. Most (n = 1640; 93.8%) were papillary carcinomas (including 84 poorly differentiated/aggressive variants); 6.2% (n = 108) were follicular and Hürthle cell carcinomas. The median tumor diameter was 11 mm (range 1-93 mm). Tumors were multifocal in 613 (35%) and presented extrathyroidal extension in 492 (28%) cases. Initial treatments included total thyroidectomy (involving one or two procedures; n = 726; 98.8%) and lobectomy (n = 22; 1.2%). A quarter of the patients who underwent total thyroidectomy had unifocal, intrathyroidal tumors ≤1 cm (n = 408; 23.6%). Neck dissection was performed in 40.4% of the patients (29.5% had central compartment dissection). Radioiodine remnant ablation (RRA) was performed in 1057 (61.2%) of the 1726 patients who underwent total thyroidectomy: 460 (41.2%) of the 983 classified by 2009 ATA guideline criteria as low-risk, 570 (87.1%) of the 655 as intermediate-risk, and 82 (93.1%) of the 88 as high-risk patients (p < 0.001). RRA was performed in 44% of the cases involving multifocal DTCs measuring ≤1 cm. CONCLUSIONS The treatment approaches for DTCs used in Italy display areas of inconsistency with those recommended by the 2009 ATA guidelines. Italian practices were characterized by underuse of thyroid lobectomy in intrathyroidal, unifocal DTCs ≤1 cm. The use of RRA was generally consistent with risk-stratified recommendations. However, its frequent use in small DTCs (≤1 cm) that are multifocal persists, despite the lack of evidence of benefit. These data provide a baseline for future assessments of the impact of international guidelines on DTC management in Italy. These findings also illustrate that the dissemination and implementation of guideline recommendations, and the change in practice patterns, require ongoing education and time.

Abstract
BACKGROUND The term "nodular goiter" has long been used to refer to a nodular thyroid gland, based on the assumption that nodule growth may be associated with hyperplasia of the surrounding non-nodular tissue. The aim of this prospective, multicenter, observational study was to determine whether nodule growth is accompanied by growth in the non-nodular tissue. METHODS Eight Italian thyroid-disease referral centers enrolled 992 consecutive patients with one to four benign nodules. Nodular and non-nodular thyroid tissue volumes were assessed for five years with annual ultrasound examinations. RESULTS In participants whose nodules remained stable (n = 839), thyroid volumes did not change (baseline 15.0 mL [confidence interval (CI) 14.5-15.6]; five-year evaluation 15.1 mL [CI 14.5-15.7]). In participants with significant growth of one or more nodule (n = 153), thyroid volumes increased and by year 5 were significantly greater than those of the former group (17.4 mL [CI 16-18.7]). In 76 individuals with unilateral nodules that grew, the mean nodular lobe volume significantly exceeded that of the contralateral lobe (8.6 mL [CI 7.4-9.8] vs. 6.7 mL [CI 6-7.4]). The unaffected lobe volumes remained stable over time, while nodular lobes grew steadily and were significantly greater at the end of follow-up (10.1 mL [CI 8.9-11.3]). Excluding the volume of the largest growing nodule in these cases, the remaining volume of the affected lobe remained virtually unchanged with respect to its baseline value. Furthermore, there was no significant difference in the non-nodular tissue volume between the unaffected lobe and the affected lobe (with the largest growing nodule volume subtracted), both at baseline and at the end of follow-up. CONCLUSIONS The growth of thyroid nodules is a local process, not associated with growth of the surrounding non-nodular tissue. Therefore, a normal-sized thyroid containing nodules should be referred to as a "uni- or multinodular thyroid gland" and considered a distinct entity from "uni- or multinodular goiter."

Abstract
Papillary thyroid cancer (PTC) patients treated with thyroidectomy and radioiodine remnant ablation (RRA) often have detectable TSH-stimulated thyroglobulin (Tg) levels without localizable disease after primary treatment. To assess the value of repeat stimulated Tg assays in these patients' follow-up, we retrospectively analyzed 86 cases followed in 5 Italian thyroid-cancer referral centers. We enrolled 86 patients with PTCs treated with total/near-total thyroidectomy plus RRA between January 1,1990 and January 31, 2006. In all cases, the initial postoperative visit revealed stimulated serum Tg ≥1 ng/mL, negative Tg antibodies, and no structural evidence of disease. None received empiric radioiodine therapy. Follow-up (median: 9.6 years) included neck ultrasound and basal Tg assays (yearly) and at least 1 repeat stimulated Tg assay. Of the 86 patients analyzed (initial risk: low 63 %, intermediate 35 %, high 2 %), one (1 %) had ultrasound-detected lymph node disease and persistently elevated stimulated Tg levels at 3 years. In 17 (20 %), imaging findings were consistently negative, but the final stimulated Tg levels was still >1 ng/mL (median 2.07 ng/mL, range 1.02-4.7). The other 68 (80 %) appeared disease-free (persistently negative imaging findings with stimulated Tg levels ≤1 ng/mL). Mean intervals between first and final stimulated Tg assays were similar (5.2 and 4.8 years) in subgroups with versus without Tg normalization. Reclassification as disease-free was significantly more common when initial stimulated Tg levels were indeterminate (<10 ng/mL). In unselected PTC cohorts with incomplete/indeterminate biochemical responses to thyroidectomy and RRA, periodic remeasurement of stimulated Tg allows most patients to be classified as disease-free.

Abstract
IMPORTANCE Detection of asymptomatic thyroid nodules has increased. Consensus is lacking regarding the optimal follow-up of cytologically proven benign lesions and sonographically nonsuspicious nodules. Current guidelines recommend serial ultrasound examinations and reassessment of cytology if significant growth is observed. OBJECTIVE To determine the frequency, magnitude, and factors associated with changes in thyroid nodule size. DESIGN, SETTING, AND PARTICIPANTS Prospective, multicenter, observational study involving 992 consecutive patients with 1 to 4 asymptomatic, sonographically or cytologically benign thyroid nodules. Patients were recruited from 8 hospital-based thyroid-disease referral centers in Italy between 2006 and 2008. Data collected during the first 5 years of follow-up, through January 2013, were analyzed. MAIN OUTCOMES AND MEASURES Baseline nodule growth (primary end point) was assessed with yearly thyroid ultrasound examinations. Size changes were considered significant for growth if an increase of 20% or more was recorded in at least 2 nodule diameters, with a minimum increase of 2 mm. Baseline factors associated with growth were identified. Secondary end points were the sonographic detection of new nodules and the diagnosis of thyroid cancer during follow-up. RESULTS Nodule growth occurred in 153 patients (15.4% [95% CI, 14.3%-16.5%]). One hundred seventy-four of the 1567 original nodules (11.1% [95% CI, 10.3%-11.9%]) increased in size, with a mean 5-year largest diameter increase of 4.9 mm (95% CI, 4.2-5.5 mm), from 13.2 mm (95% CI, 12.1-14.2 mm) to 18.1 mm (95% CI, 16.7-19.4 mm). Nodule growth was associated with presence of multiple nodules (OR, 2.2 [95% CI 1.4-3.4] for 2 nodules; OR, 3.2 [95% CI, 1.8-5.6 for 3 nodules; and OR, 8.9 [95% CI, 4.4-18.0] for 4 nodules), main nodule volumes larger than 0.2 mL (OR, 2.9 [95% CI, 1.7-4.9] for volumes >0.2 to <1 mL and OR, 3.0 [95% CI, 1.8-5.1] for volumes ≥1 mL), and male sex (OR, 1.7 [95% CI, 1.1-2.6]), whereas an age of 60 years or older was associated with a lower risk of growth than age younger than 45 years (OR, 0.5 [95% CI 0.3-0.9]). In 184 individuals (18.5% [95% CI, 16.4%-20.9%]), nodules shrank spontaneously. Thyroid cancer was diagnosed in 5 original nodules (0.3% [95% CI, 0.0%-0.6%]). Only 2 had grown. An incidental cancer was found at thyroidectomy in a nonvisualized nodule. New nodules developed in 93 patients (9.3% [95% CI, 7.5%-11.1%]), with detection of one cancer. CONCLUSIONS AND RELEVANCE Among patients with asymptomatic, sonographically or cytologically benign thyroid nodules, the majority of nodules exhibited no significant size increase during 5 years of follow-up and thyroid cancer was rare. These findings support consideration of revision of current guideline recommendations for follow-up of asymptomatic thyroid nodules.

Abstract
OBJECTIVE The association between papillary thyroid cancer (PTC) and Hashimoto's thyroiditis is widely recognized, but less is known about the possible link between circulating anti-thyroglobulin antibody (TgAb) titers and PTC aggressiveness. To shed light on this issue, we retrospectively examined a large series of PTC patients with and without positive TgAb. METHODS Data on 220 TgAb-positive PTC patients (study cohort) were retrospectively collected in 10 hospital-based referral centers. All the patients had undergone near-total thyroidectomy with or without radioiodine remnant ablation. Tumor characteristics and long-term outcomes (follow-up range: 2.5-24.8 years) were compared with those recently reported in 1020 TgAb-negative PTC patients with similar demographic characteristics. We also assessed the impact on clinical outcome of early titer disappearance in the TgAb-positive group. RESULTS At baseline, the study cohort (mean age 45.9 years, range 12.5-84.1 years; 85% female) had a significantly higher prevalence of high-risk patients (6.9% vs. 3.2%, p<0.05) and extrathyroidal tumor extension (28.2% vs. 24%; p<0.0001) than TgAb-negative controls. Study cohort patients were also more likely than controls to have persistent disease at the 1-year visit (13.6% vs. 7.0%, p=0.001) or recurrence during subsequent follow-up (5.8% vs. 1.4%, p=0.0001). At the final follow-up visit, the percentage of patients with either persistent or recurrent disease in the two cohorts was significantly different (6.4% of TgAb-positive patients vs. 1.7% in the TgAb-negative group, p<0.0001). At the 1-year visit, titer normalization was observed in 85 of the 220 TgAb-positive individuals. These patients had a significantly lower rate of persistent disease than those who were still TgAb positive (8.2% vs. 17.3%. p=0.05), and no relapses were observed among patients with no evidence of disease during subsequent follow-up. CONCLUSIONS PTC patients with positive serum TgAb titer during the first year after primary treatment were more likely to have persistent/recurrent disease than those who were consistently TgAb-negative. Negative titers at 1 year may be associated with more favorable outcomes.

Abstract
BACKGROUND/AIM Maternal thyroid dysfunction during pregnancy has been associated with adverse obstetric and neonatal outcomes. This prospective study evaluates the prevalence of these disorders in pregnant women. SUBJECTS AND METHODS Serum levels of TSH, free T4 (fT4), and thyroperoxidase antibodies (TPO-Ab) were measured in 951 women at different gestational ages of pregnancy. Trimester-specific reference ranges for TSH were used to classify pregnant women into five groups: 1) Overt hypothyroidism (OH); 2) Subclinical hypothyroidism (SCH); 3) Isolated hypothyroxinemia (IH); 4) Low TSH (isolated or associated with high fT4); and 5) Normal. A classification was made also according to the lower and upper ranges provided by the manufacturer for thyroid hormones. Pregnant women who were at a high risk of developing thyroid disease were identified. RESULTS Altogether, 117 women (12.3%) had hypothyroidism and 25 (2.6%) had low TSH. The prevalence of both OH and SCH was higher in the high-risk group than in the low-risk group, but 17.9% of women with hypothyroidism were classified at low-risk. A family history of thyroid disorders and TPO-Ab positivity increased the risk of SCH. Using non-pregnant reference range for TSH, 10.6% of women were misclassificated. CONCLUSIONS The high prevalence of hypothyroidism observed in this study suggests that accurate thyroid screening with trimester specific reference ranges should be warranted, particularly in areas with mild to moderate iodine deficiencies.

Abstract
CONTEXT The current use of life-long follow-up in patients with papillary thyroid cancer (PTC) is based largely on the study of individuals diagnosed and treated in the latter half of the 20th century when recurrence rates were approximately 20% and relapses detected up to 20-30 years after surgery. Since then, however, diagnosis, treatment, and postoperative monitoring of PTC patients have evolved significantly. OBJECTIVES The objective of the study was to identify times to PTC recurrence and rates by which these relapses occurred in a more recent patient cohort. PATIENTS AND DESIGN We retrospectively analyzed follow-up data for 1020 PTC patients consecutively diagnosed in 1990-2008 in 8 Italian hospital centers for thyroid disease. Patients underwent thyroidectomy, with or without radioiodine ablation of residual thyroid tissue and were followed up with periodic serum thyroglobulin assays and neck sonography. RESULTS At the initial posttreatment (≤ 12 months) examination, 948 patients had no structural/functional evidence of disease. During follow-up (5.1-20.4 years; median 10.4 years), recurrence (cervical lymph nodes, thyroid bed) was diagnosed in 13 (1.4%) of these patients. All relapses occurred 8 or fewer years after treatment (10 within the first 5 years, 6 within the first 3 years). Recurrence was unrelated to the use/omission of postoperative radioiodine ablation. CONCLUSION In PTC patients whose initial treatment produces disease remission (no structural evidence of disease), recurrent disease is rare, and it usually occurs during the early postoperative period. The picture of recurrence timing during the follow-up provides a foundation for the design of more cost-effective surveillance protocols for PTC patients.

Abstract
CONTEXT Serum thyroglobulin (Tg) assays are considered fundamental in postoperative surveillance of differentiated thyroid cancer (DTC) patients. However, the postsurgical profile of Tg levels has never been specifically investigated in patients who do not undergo radioiodine remnant ablation (RRA). OBJECTIVES Our objective was to explore the evolution of Tg levels over time in DTC patients treated with total or near-total thyroidectomy without RRA. DESIGN We retrospectively analyzed 290 consecutively diagnosed cases of low-risk (American Thyroid Association criteria) DTC treated with thyroidectomy alone and followed yearly with neck ultrasonography and serum Tg assays. We compared final Tg values in this group and a matched group of 495 RRA-positive patients. Temporal trends of serial Tg levels were also analyzed in 78 of the RRA-negative patients monitored with a high-sensitivity immunoradiometric assay. RESULTS After follow-up of 2.5-22 yr (median 5 yr), final Tg levels were undetectable (<1 ng/ml) in 274 of 290 RRA-negative patients (95%) and 492 of 495 RRA-positive controls (99%). In the subset of 78 RRA-negative patients, undetectable Tg levels (<0.2 ng/ml) were recorded in 60% at the first postoperative evaluation (3-12 months) and in 79% after 5 yr. Tg levels increased in the single patient who experienced disease recurrence during the observation period. CONCLUSION In most RRA-negative patients, postoperative serum Tg values spontaneously drop to undetectable levels within 5-7 yr after thyroidectomy. Thus, in later phases, Tg assays may be a valuable tool for follow-up even in patients who do not undergo RRA.

Abstract
We have recently demonstrated the diagnostic value of a new immunophenotype of blood endothelial progenitor cells (EPCs=CD45neg/CD34pos/CD144pos) and endothelial microparticles (EMPs=CD45neg/CD144pos/AnnexinVpos) in patients with arterial erectile dysfunction (ED) according to severity of cavernous arterial insufficiency evaluated through penile Doppler. The aim of this study was to evaluate both EPCs and EMPs in patients with arterial ED and metabolic syndrome (MetS), comparing these patients with another group of patients without MetS and ED and a third group with MetS but without ED. For this study 50 patients with arterial ED and MetS were selected (age: 55.0±3.0 years; range: 47-60). A group of age-matched (age: 54.0±2.0 years; range: 44-60) patients without arterial ED and MetS (n=30), and another group of age-matched (age: 57.0±4.0 years; range: 40-62) patients with MetS but without ED (n=20) represented the control groups. EPCs and EMPs were significantly higher in patients compared with other groups (P<0.01). Both EPCs and EMPs correlated positively with the age, body mass index, and score of international index of ED (version five items) and with the following cavernous artery indices: peak systolic velocity, acceleration time and intima-media thickness. Among control groups patients with MetS but without ED showed serum concentrations of EPCs and EMPs significantly higher (P<0.05) compared with patients without MetS and ED. Patients with arterial ED and MetS have higher EPCs and EMPs compared with patients with MetS but without ED and patients without MetS and ED.

Abstract
We previously reported that the NO-modified form of HIV protease inhibitor Saquinavir (Saq) is a potent antitumoral agent efficient against numerous tumor cell lines in vitro and in vivo. In acute toxicity studies, doses of Saq-NO equivalent to DL100 of the parental drug were completely nontoxic. Beside direct effect on malignant cell growth, Saq-NO sensitizes certain type of cells to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-mediated cell death. In this study, we evaluated the effects of Saq-NO on androgen-dependent prostate cancer LNCaP. Saq-NO inhibited both the growth of LNCaP cells in vitro and in xenograft models. Suppression of tumor growth was accompanied with cell cycle arrest in G 0/G 1 phase and established a persistent inhibition of proliferation. Furthermore, Saq-NO reverted sensitivity of LNCaP cells to TRAIL but not to TNF. Treatment of cells with Saq-NO induced transient upregulation of Akt and ERK1/2. This, however, did not represent the primary mode of action of Saq-NO, as elimination with specific inhibitors did not compromise the chemotherapic efficacy of the drug. However, permanent abrogation of phosphorylation of the S6 protein, which is the downstream target of both signaling pathways, was observed. Diminished S6 phosphorylation was associated with re-established sensitivity to TRAIL and reduction of X-linked inhibitor of apoptosis protein (XIAP). In summary, NO modification of Saq led to a new chemical entity with stronger and more pleiotropic antitumor activity than the parental drug.

Abstract
CONTEXT Most papillary thyroid microcarcinomas (PTMCs; ≤ 1 cm diameter) are indolent low-risk tumors, but some cases behave more aggressively. Controversies have thus arisen over the optimum postoperative surveillance of PTMC patients. OBJECTIVES We tested the hypothesis that clinical criteria could be used to identify PTMC patients with very low mortality/recurrence risks and attempted to define the best strategy for their management and long-term surveillance. DESIGN We retrospectively analyzed data from 312 consecutively diagnosed PTMC patients with T1N0M0 stage disease, no family history of thyroid cancer, no history of head-neck irradiation, unifocal PTMC, no extracapsular involvement, and classic papillary histotypes. Additional inclusion criteria were complete follow-up data from surgery to at least 5 yr after diagnosis. All 312 had undergone (near) total thyroidectomy [with radioactive iodine (RAI) remnant ablation in 137 (44%) - RAI group] and were followed up yearly with cervical ultrasonography and serum thyroglobulin, TSH, and thyroglobulin antibody assays. RESULTS During follow-up (5-23 yr, median 6.7 yr), there were no deaths due to thyroid cancer or reoperations. The first (6-12 months after surgery) and last postoperative cervical sonograms were negative in all cases. Final serum thyroglobulin levels were undetectable (<1 ng/ml) in all RAI patients and almost all (93%) of non-RAI patients. CONCLUSION Accurate risk stratification can allow safe follow-up of most PTMC patients with a less intensive, more cost-effective protocol. Cervical ultrasonography is the mainstay of this protocol, and negative findings at the first postoperative examination are highly predictive of positive outcomes.

Abstract
AIM Nodular thyroid disease and osteoporosis share some common factors such as: 1) elevated frequency in the general population; 2) major prevalence in the female sex; 2) incidence proportional to the age. There is a wide debate in literature regarding the real impact of chronic treatment with L-thyroxin (LT4) on the bone mineral density (BMD), especially in post-menopausal women. The aim of this study was to undertake to evaluate the effects of LT4 administration for the treatment of normo-functioning nodular thyroid disease on the BMD in post-menopausal women after one year of continuative treatment. Particular attention was paid in examining the role of some anamnestic risk factors for osteoporosis on the clinical response. METHODS Ninety nine postmenopausal women of age comprised between 50 and 56 years were examined before and after 1 year of therapy with a fixed dose of LT4 for the treatment of nodular thyroid disease by monitoring the following laboratory parameters: thyroid stimulating hormone (TSH), FT4, FT3, antithyroglobulin antibodies [AbTG], hyroid peroxidase antibodies [AbTPO], serum calcium and alkaline phosphatase levels and 24-urinary excretion of calcium and hydroxyproline. Bone mineral density (BMD) was measured by dual X-ray absorptiometry of the lumbar vertebrae. RESULTS The results of this study showed that the patients on treatment with LT4 have a slight, but significant reduction of the BMD after 1 year of treatment, associated with increased serum levels of alkaline phosphatase and urinary excretion of hydroxyproline. Comparison between patients with unsuppressed (group A) or suppressed (group B) TSH following LT4 treatment showed that group B patients had significantly lower BMD. The following risk factors influenced, in a statistically significant manner, the BMD: 1) Body Mass Index <19 kg/m(2); 2) the onset of menarche after the age of 15 years; 3) history positive for period of amenorrhoea; 4) nulliparity; 5) surgical menopause; 6) lack of hormonal replacement therapy; and 7) presence of auto-antibodies against thyroid antigens. CONCLUSION LT4 treatment in postmenopausal women reduced significantly the BMD. This treatment should be therefore prescribed with caution in this condition and particularly when the following risk factors are present: surgically driven menopause, constitutional thinness, history of nulliparity, absence of hormonal treatment, positive history of secondary amenorrhoea during the reproductive age, autoimmune thyroid disease and delayed menarche.

Abstract
BACKGROUND Serum thyroglobulin (Tg) stimulation by recombinant human TSH (rhTSH), in combination with neck ultrasonography (US), is an important tool in the first follow-up of differentiated epithelial cell thyroid carcinoma (DTC) patients. The objective of this study was to investigate if a second rhTSH stimulation, performed 2-3 years later, is of clinical utility in the follow-up of these patients. METHODS One hundred and one consecutive ambulatory DTC patients were studied. The great majority of them (89/101) were low-risk patients, being stage I or II at tumor node metastasis (TNM) staging classification. All study patients had been treated by surgery and radioiodine ablation, and exhibited, at first rhTSH follow-up, either undetectable Tg (<or=1 ng/mL) (rhTSH1-Tg-, n = 89 patients considered as free of disease) or low Tg (>1-5 ng/mL) (rhTSH1-Tg+, n = 12 patients considered with uncertain prognosis), with no US evidence of residual disease. In all patients, serum Tg measurement after a second rhTSH stimulation and neck US were performed. RESULTS At the second follow-up, all 89 rhTSH1-Tg-patients showed a negative US, and Tg became low positive only in one case, whereas it remained undetectable in the other patients. The overall negative predictive value of rhTSH1-Tg- was, then, 98.9%. Out of the remaining 12 patients (i.e., rhTSH1-Tg+ patients), 2 showed disease persistence/recurrence (with a positive predictive value of rhTSH1-Tg+ of 16.7%) and 6 became Tg-. CONCLUSIONS A second rhTSH stimulation is useless in DTC patients who were rhTSH-Tg and imaging negative at first follow-up, while it is suggested in patients with detectable, although low, rhTSH-Tg levels at first follow-up: in the absence of clinical or US evidence of disease persistence, these patients should not be retreated by radioiodine, but simply scheduled for a later rhTSH stimulation.

Abstract
AIM Recently, the clinic characterization of the gonadic male function has been put in tight correlation on the pathogenetic level with the main variables forming the condition of metabolic syndrome (MS); probably the serum testosterone (T) concentration in males is to be considered as an additional parameter completely related to the traditional clinical-metabolic findings. Currently the matter of the substitutive hormonal therapy with androgens is apparently influenced by some important unresolved aspects: 1) who really benefits from the T therapy? 2) are the actual dosage methods of T reliable? 3) which vascular and metabolic targets are to be monitored during the T therapy? METHODS In an analytical longitudinal study, carried out 12 months long on 60 men (average age 58 years, range 54-63 years) affected by metabolic syndrome (MS) and combined hypogonadism late onset (LOH), authors have evaluated the clinical response (androgenic asset, non-invasive hospital monitoring of the arterial pressure, lipidic asset study, body composition and the biologic resistance to the insulinic action) after conventional medical therapy (insulin-sensibilizing and anti-hypertensive) and after substitutive hormonal therapy with testosterone (T) by transdermic way. A group of five patients with MS and LOH, not treated, was used as group of control. RESULTS The group of patients treated with T showed a profile of clinical response better than the group of controls. CONCLUSIONS In conclusion, the seric determination of T is useful to better characterize the dismetabolic patient at the moment of the first level active medical therapy planning on the controls of the main risk factors constituting MS, expressing a potential role of conditioning.

Abstract
Recombinant human TSH (rhTSH) has been recently suggested for radioiodine ablation in patients with differentiated thyroid cancer (DTC). To date, studies are still not available about the effectiveness of rhTSH stimulation depending on the age, since serum TSH clearance may be different in younger and in older patients. The aim of this study was to investigate the influence of age to serum TSH levels after rhTSH stimulation and thyroid hormone withdrawal (THW). We retrospectively evaluated two groups of consecutive DTC patients: group 1 (311 patients, age 49.0+/-13.6 years, ranging 15-86) underwent rhTSH stimulation 6-12 months after thyroid ablation (rhTSH-group); group 2 (84 patients, age 46.9+/-13.5 years, ranging 20-77) was followed by THW (THW-group). The influence of age, gender, body mass index and body surface area to serum TSH levels were evaluated in both groups. RhTSH-group: on day 5 (d5), TSH levels were 32.7+/-21.4 microU/ml (range 0.8-136.6). By univariate analysis, d5-TSH was positively related to age (r=0.27, p=0.0001) and no correlations were found with the other parameters. At multivariate analysis, both age and gender (female) were independently associated with d5-TSH levels. THW-group: after thyroid hormone withdrawal, TSH levels were 71.1+/-36.4 microU/ml (range 8.5-200). At univariate analysis, only age was significantly and negatively related to serum TSH levels (r=-0.31, p=0.004). Our data indicate that age and gender seem to positively influence serum TSH levels after rhTSH stimulation. An opposite effect of age on serum TSH levels has been observed after THW. Therapeutic implications ((131)I-treatment) of these findings have to be better investigated in prospective studies.

Abstract
CONTEXT Routine serum calcitonin (CT) measurement in patients with thyroid nodules for diagnosis of medullary thyroid carcinoma (MTC) is controversial. OBJECTIVE The objective of this study was to evaluate the diagnostic accuracy of systematic CT measurement in non-multiple endocrine neoplasia type 2 patients with nodular thyroid disease. SETTINGS This study was conducted at a national healthcare system hospital (outpatient and inpatient sectors). SUBJECTS Consecutive patients with nodular thyroid disease (n = 5817) were studied. MAIN OUTCOME MEASURES Serum CT levels were measured under basal conditions, and when basal values were more than or equal to 20 and less than 100 pg/ml, testing was repeated after pentagastrin stimulation. Basal or stimulated levels more than 100 pg/ml were indication for surgery. RESULTS Fifteen cases of MTC and seven of C cell hyperplasia (CCH) were identified. MTCs were diagnosed in all patients with basal CT more than 100 pg/ml. The four patients with basal CT more than or equal to 50 and less than 100 pg/ml included two diagnosed with MTC and two with CCH. In 10 patients with basal levels more than or equal to 20 and less than 50 pg/ml, histology confirmed the presence of MTC in four, four others had CCH, and the remaining two were negative for thyroid malignancy. Positive predictive values for basal CT levels in the preoperative diagnosis of MTC were: 23.1% for values more than or equal to 20 pg/ml, 100% for values more than 100 pg/ml, 25% for levels more than or equal to 50 and less than 100 pg/ml, and 8.3% for values more than or equal to 20 and less than 50 pg/ml. Positive predictive values for the pentagastrin test (>100 pg/ml) were 40% in the entire series. CONCLUSIONS CT screening of thyroid nodules is a highly sensitive test for early diagnosis of MTC, but confirmatory stimulation testing is necessary in most cases to identify true positive increases.

Abstract
Persistent or recurrent disease is rare in low risk patients with papillary thyroid cancer, and follow-up of these patients is a matter of debate. Neck ultrasonography (US), serum thyroglobulin (Tg), and whole body scan (WBS) after T(4) withdrawal were performed in 456 patients, followed up to 5 yr. At the end of the first year, 335 patients were Tg negative, and 121 were Tg positive; 65 of 96 patients with Tg levels between 1 and 10 ng/ml became spontaneously Tg negative after 2 yr. During follow-up, WBS discovered node metastases in 13 subjects, and US discovered node metastases in 38 subjects (31 Tg positive and 7 Tg negative). WBS did not add any information, because all WBS-positive patients were also US and Tg positive. Fifty percent of metastases were less than 1 cm and not palpable. Finally, the negative predictive value of both negative Tg and US at first follow-up was 98.8%. We suggest a first follow-up based upon US assessment and stimulated (after T(4) withdrawal or recombinant human TSH) serum Tg determination; subsequently, 1) US should not be mandatory at each examination in initially Tg- and US-negative subjects, but is strongly suggested in all other cases; 2) Tg determination should be repeated 1 yr later, after exogenous or endogenous TSH stimulation only in initially Tg-positive patients without any other evidence of residual disease; and 3) Tg measurement during therapy should be sufficient in all other cases.

Abstract
The adrenal localization of a primary non-Hodgkin lymphoma (NHL) is rare. We report a case of a 66-yr-old woman who had severe asthenia, diffuse skin hitching and abdominal pain. The physical examination revealed poor general conditions, irritability, pallor, dehydration and diffuse skin scratching lesions. The abdomen was painful at left hypochondrium and the Giordano's maneuvre was positive on both sides. A peripheral blood smear showed the presence of big rare lymphocytes with dyshomogeneous chromatin and granulated and hyperbasophil cytoplasm. She underwent abdominal ultrasonography which showed the presence of a hypoechogenic ovoidal mass (major diameter 8.4 cm) within the splenorenal left region. The presence of the suprarenal mass was confirmed by computed tomography (CT) scan which showed an enlarged left adrenal gland (8.1 x 6.2 cm) of solid structure. The right adrenal gland was also enlarged and of round shape (4.5 cm). CT scan-guided fine needle aspiration biopsy was then carried out on the left adrenal mass. It revealed the presence of NHL type B with large cells and modest T-lymphocyte reactive component. The patient was treated with three cycles of cyclophosphamide, adriamycin, vincristine and prednisolone. At the end of the third cycle, there was a transient clinical improvement and the hitching disappeared, but the patient worsened rapidly and she died few weeks later.

Abstract
Constitutively activating germline mutations of the TSH receptor (TSH-R) are considered the cause of hereditary non-autoimmune hyperthyroidism. In this study, 10 members (8 affected and 2 unaffected) of an Italian family with hereditary non-autoimmune hyperthyroidism were investigated for the presence of mutations in the TSH-R gene. The clinical features of the disease were also analyzed. PCR-amplified fragments of the TSH-R gene were obtained from genomic DNA extracted from peripheral blood leukocytes of each family member and analyzed by direct nucleotide sequencing and restriction analysis. An identical germline TSH-R mutation was detected in all the patients with hyperthyroidism but in none of the unaffected family members. The mutation was heterozygotic and determined the substitution of valine for methionine (codon 463; ATG-->GTG) in the second transmembrane domain of the TSH-R. When expressed in chinese hamster ovary (CHO) cells, the Val463 mutant TSH-R induced constitutive activation of the TSH receptor. Analysis of the clinical features of our family and those of other families with hereditary non-autoimmune hyperthyroidism, including one with the same Val463 mutation, revealed wide variability in the phenotypical expression of the disease. Our findings indicate that an activating germline mutation in the TSH-R gene plays a key role in hereditary non-autoimmune hyperthyroidism although the onset of clinical manifestations and the evolution of the disease seem to depend heavily on other factors, thus far unidentified. The absence of a clear correlation between mutant genotypes and phenotypic expression of the disease currently limits the prognostic value of genetic testing in families with hereditary non-autoimmune hyperthyroidism.

Abstract
Azoospermia factor (AZF) region microdeletions, which account for about 10-15% of patients with oligoazoospermia, seem to lack a close genotype-testicular phenotype correlation. Although many genetic and non-genetic factors may contribute to this outcome, it was thought that a spontaneous regression of testicular germ cells might also play a relevant role. The opportunity for carrying out two different testicular biopsies one year apart in an AZFc-microdeleted patient enabled corroboration of this possibility. Indeed, the first biopsy showed a spermatocyte maturation arrest with mean Johnsen scores of 4 and 3.9 in the right and left testes respectively. One year later, the right testicular biopsy showed a picture of Sertoli cell-only syndrome in 90% of the tubules examined, and of spermatogonial maturation arrest in the remaining tubules, with a mean Johnsen score of 2.1. The almost complete absence of germinal cells was confirmed by four left testicular sperm aspirations (TESA), conducted at the same time as the biopsy during an intracytoplasmic sperm injection cycle, which showed the almost exclusive presence of Sertoli cells (85% of the whole cell population). No spermatozoa could be retrieved by TESA or testicular biopsy. To our knowledge, this is the first case of a spontaneous regression of the germinal cell epithelium over time in a patient with a Yq microdeletion without the apparent intervention of any cause known to affect the germinal epithelium.

Abstract
We report a case in which the appearance of a progressively rising titer of thyroglobulin (Tg) antibodies was the most sensitive marker of papillary thyroid cancer relapse at loco-regional lymph nodes. The patient, a 60-year-old man, had been treated with total thyroidectomy plus lymphadenectomy and radioiodine ablation for a 1-cm papillary thyroid cancer. Twelve years after surgery, while undergoing levothyroxine (LT4) therapy, Tg antibodies were first detected and progressively rose from 99 to 1,697 U/mL in 18 months, while serum Tg remained undetectable. Both neck ultrasonography and 131I whole-body scan (WBS) were unremarkable. Enlarged lymph nodes became palpable at the left laterocervical region only 2 years after the first appearance of Tg antibodies and were surgically removed after cancer relapse was confirmed by fine-needle aspiration cytology. This case emphasizes the possibility that in thyroid cancer patients who have undergone total thyroidectomy, the appearance of Tg antibodies may indicate metastatic lymph nodes even when serum Tg is undetectable and WBS negative.

Abstract
We report three cases of autonomously functioning thyroid nodules (AFTNs) that appeared hypofunctioning at radioactive iodine (131I) thyroid scan carried out at initial observation. Since at that time thyroid hormones and thyrotropin (TSH) were also normal, they were initially classified as "cold" nodules and treated with levothyroxine (LT4). The correct diagnosis of AFTN was made years later when a thyroid scintigraphy was repeated. In two of these patients, re-evaluation of the nodule was done because of the development of LT4 intolerance. A possible explanation is that these AFTNs had undergone hemorrhagic/cystic degeneration when they were first studied, but in subsequent years, proliferation of residual AFTN tissue caused the recurrence of a typical functioning nodule.

Abstract
Thyroid carcinomas, even when well differentiated, usually appear as hypofunctioning at scintigraphy. We report a case of an aggressive insular thyroid carcinoma presenting as an autonomously functioning thyroid nodule and causing severe thyrotoxicosis. The tumor was metastatic to a cervical lymph node and both lungs. An activating mutation of the TSH receptor gene in both the primary tumor and the lymph node metastasis was found, due to a base substitution at codon 633 (normal guanine at position 1896 replaced by cytosine CAC for GAC causing aspartic acid substitution by histidine). Other known oncogenes (gsp, ras, PTC/ret, trk, met, and p53) were not involved. This is the first description of an activating TSH receptor mutation in a thyroid hyperfunctioning carcinoma in which an aggressive malignant phenotype coexisted with activation of the cAMP cascade and differentiated thyroid functions.

Abstract
"Autonomous" thyroid nodule is a localized nodular lesion of the thyroid gland characterized by growth, iodine uptake and function, all independent from TSH control. These nodules represent a heterogeneous anatomic and clinical entity. The clinical diagnosis is based upon a negative suppression of nodule iodine uptake and scan imaging by T3 administration. The nodule function is determined by high serum thyroid hormone levels and/or low TSH (measured by ultrasensitive assay). Etiology and pathogenesis of these nodules is not yet completely clarified. Both genetic and environmental factors determine nodule growth and function: thyroid cells, in fact, are genetically heterogeneous and may have intrinsic (congenital) characteristics that may promote the growth of cellular clones having mitotic and functional activity that is partially independent of TSH. In these particular cell clones, environmental factors like iodine deficiency or other goitrogens may favour the growth of autonomous nodules and also, by activating their function, may induce toxicity. The autonomous thyroid nodules need to be treated only when they become toxic: in this case both surgical excision or radioiodine may be used.
