No full textIl Liceo Dantesco di Leonardo Antonio Forleo
No full textEnThe present essay is concerned with highlighting the figure and the interpretation of Dante's poetry in the Commedia of Leonardo Antonio Forleo, an italian author from Salento (a fervent liberal in the years of the Neapolitan Constitution, and therefore, following the Bourbon repression, a defender of Catholic-reactionary ideals), in his book Liceo Dantesco ovvero Guida allo studio di Dante (1844), highlighting above all the moralistic intentions of the author, who reads the Dante's Commedia almost always favoring a criticism characterized by the presence of meticulous observations aimed at always discerning ethics in poetry.ItIl presente studio si occupa di mettere in evidenza la figura e l'interpretazione dantesca del salentino Leonardo Antonio Forleo (fervente liberale negli anni della Costituzione napoletana, trasformatosi in difensore degli ideali cattolico-reazionari dopo la repressione borbonica) nel suo saggio Liceo Dantesco ovvero Guida allo studio di Dante (1844), sottolineando soprattutto gli intenti moralistici dell'autore, che legge la Commedia dantesca quasi sempre privilegiando una critica caratterizzata dalla presenz a di minuziose osservazioni tese a scorgere l'etica nella poesia
Leonardo Antonio Forleo e la ‘Divina Commedia’: il «libro verseggiato di morale»
No full textThe essay proposes the analysis of Guida allo studio di Dante, published in 1844 by Leonardo Antonio Forleo, an Apulian scholar whose crit-ics have recognized the merit of having contrib-uted to the cult and reading of Dante in Salento.Through precise and constant references to the text, the intention of the author is highlighted to detect the poetic, scientific and ethical beau-ties of Dante's Comedy, but also its allegorical contents, in order to instruct the 'valiant Italian youth' to which, motivated with a solid classi-cistic background, Forleo recommends reading and studving the poem as a source of good stud-ies and as the mother of poetry and of the Ital-ian language
The Combination of Sonographic Features and the Seven-Gene Panel May be Useful in the Management of Thyroid Nodules With Indeterminate Cytology
No full textIntroduction: The management of patients with indeterminate thyroid nodules, which account for 10–25% of thyroid fine needle aspiration biopsies (FNABs), is still very challenging. Aim: To verify the utility of the seven-gene panel in combination with ultrasound features in the clinical management of indeterminate thyroid nodules. Results: The study group included 188 indeterminate thyroid nodules, divided into TIR3A (56.4%) and TIR3B (43.6%). A significant correlation between US categories and both cytological and molecular results was observed. In detail, TIR3B cytology was more frequent in EU-TIRADS 4 and 5 nodules (54.7 and 50%, respectively) than in EU-TIRADS 2 and 3 nodules (31%, p = 0.04). Similarly, the rate of a nodule with a mutation increased with the increase of US risk class (6.0% in EU-TIRADS 2 and 3, 9.3% in EUTIRADS-4 and 27.8% in EUTIRAD-5, p = 0.01). Among thyroid nodules submitted to surgery, final histology was benign in 61.4% nodules, while malignancy was diagnosed in 38.6% nodules. Using US score as tool for decision-making in TIR3A subgroup, we correctly classified 64.5% of thyroid nodules. The second tool (seven-gene panel test) was used in the subgroup of US high-risk nodules. By multiple tests with a series approach (US in all cases and US plus seven-gene panel in US high risk nodules) 84% of cases were correctly classified. In TIR3B nodules, using only seven-gene panel as tool for decision making, we correctly classified 61.9% of indeterminate nodules. By multiple tests with series approach (seven-gene panel in all cases and seven-gene panel plus US score in non-mutated nodules) only a slight improvement of thyroid nodule classification (66.6%) was observed. Conclusions: US score seems able to correctly discriminate between TIR3A nodules in which a conservative approach may be used, and those in which additional test, such as molecular test, may be indicated. On the contrary, in TIR3B nodules both US risk stratification and seven-gene panel seem to be of little use, because the risk of thyroid cancer remains high regardless of US score and mutational status. © Copyright © 2021 Capezzone, Cantara, Di Santo, Sagnella, Pilli, Brilli, Ciuoli, Maino, Forleo, Cartocci and Castagna
Role of age at diagnosis in defining potential familial nonmedullary thyroid cancer in kindreds with two affected members
No full textContext
The definition of familial nonmedullary thyroid cancer (FNMTC) in 2 or more first-degree relatives is controversial due to the high probability of observing a sporadic association when only 2 members of first-degree relatives are affected.
Objective
To evaluate the role of age at diagnosis in differentiating the true cases of FNMTC.
Design, Setting, Participants, and Main Outcome
From a group of 721 papillary thyroid cancer (PTC) patients, 95 familial PTC (FPTC) patients with 2 first-degree relatives have been identified. They were split in 2 groups: Group 1 consisted of both the proband and the affected relative, with age at diagnosis ≤ 45 years; Group 2 consisted of proband and/or the affected family member, with age at diagnosis > 45 years. The clinical-pathological features and outcome of both FPTC groups were compared with 626 sporadic PTC patients (SPTC).
Results
Familial PTC patients with age at diagnosis ≤ 45 years, compared with the matched group of sporadic PTCs, had a more frequent multifocal, bilateral, and extrathyroidal extension of tumor and showed worse outcome. No differences were found between FPTC and SPTC patients with age > 45 years. At multivariate analysis, distant metastases, American Thyroid Association (ATA) risk, and FPTC ≤ 45 years were independent predictors of outcome.
Conclusions
Based on the observation that PTC is more aggressive when the diagnosis is made in 2 family members, both with age < 45years, we suggest that the definition of FPTC in kindreds with 2 affected members should also take into account the age at diagnosis as a key element of familial cancer.

Bariatric surgery reduces serum anti-mullerian hormone levels in obese women with and without polycystic ovarian syndrome
No full textObesity in fertile women has negative effect on fertility. Anti-mullerian hormone (AMH)represents a good index of fertility, and it is considered a marker of ovarian reserve and of polycystic ovarian syndrome (PCOS) gravity. Previous studies evaluated the relationship between obesity and AMH with contradictory results. The aim of the study was to investigate the relationship between obesity and AMH and the changes of AMH in obese women in reproductive age submitted to bariatric surgery. Fifty-five obese patients between 18 and 39 years with (29 patients) and without PCOS (26 patients) were compared with a control group of normal weight women with (24 patients) and without PCOS (19 patients). Fourteen obese women with PCOS and 18 without PCOS underwent to bariatric surgery. Serum AMH, testosterone, androstenedione, and DHEAS were performed in all patients before and 1 year after surgical intervention. AMH was significantly higher in the PCOS groups (p < 0.001), both in obese (5.84 ± 3.94 ng/ml) and non-obese women (7.35 ± 4.39 ng/ml). AMH was positively related to testosterone (p < 0.0001), androstenedione (p = 0.0005), and DHEAS(p=0.003).After bariatric surgery, AMH levels were reduced in the both PCOS (p = 0.02) and non-PCOS group (p = 0.04). AMH levels are elevated in PCOS patients regardless of the body weight. Bariatric surgery is effective in the normalization of AMH levels (a possible indirect marker of better fertility) only in obese patients with PCOS
Preliminary results from whole-genome expression analysis in patients with secondary adrenal insufficiency treated with modified-release hydrocortisone
No full textPurpose Conventional (CONV) treatment of adrenal insufficiency (AI) is associated with risk of overtreatment: glyco-metabolic impairment, bone loss, and reduced quality of life. Recent findings suggest that modified-release hydrocortisone (MOD) may restore a more physiological cortisol profile. Our aims were: (1) to compare the gene expression profile of peripheral blood mononuclear cells derived from patients, with secondary AI (SAI), under CONV (cortisone acetate or hydrocortisone) or MOD versus healthy controls; and (2) to evaluate MOD effects on serum cortisol profile, glucose, lipid, bone, and clinical parameters.Methods Thirteen patients with SAI were switched from CONV to MOD at equivalent dose. Area under curve (AUC) of both formulations was calculated in six patients. Clinical, metabolic and bone parameters were measured at baseline and 3 months after MOD in all patients. In six patients and six age- and sex-matched healthy controls, a whole-genome expression analysis was performed at baseline, 1 month, and 3 months after MOD.Results (1) The number of genes differentially expressed (n = 235; mainly involved in immune response and metabolism) in SAI patients compared to controls progressively and significantly decreased switching from CONV to MOD (n = 78 at 3 months). (2) Under MOD: AUC of cortisol exposure tended to be smaller and cortisol levels showed a more physiological profile; no significant changes of clinical, metabolic and bone parameters were observed, likely due to the short follow-up, but triglycerides tended slightly to increase.Conclusions MOD may restore a normal gene expression profile as soon as 1 month after switching from CONV
Validation of American Thyroid Association Ultrasound Risk-Adapted Approach for Repeating Cytology in Benign Thyroid Nodules
No full textBackground:The 2015 American Thyroid Association (ATA) ultrasound (US) risk stratification system is used to identify thyroid nodules in which fine-needle aspiration cytology (FNAC) should be performed. In addition, this system is used to plan the long-term follow-up of patients with cytological benign thyroid nodules. The aim of our study was to evaluate the ATA US risk-adapted approach for repeating cytology in a large retrospective cohort of consecutive benign nodules with a second FNAC repeated after a median follow-up of 3.8 years (range 1.0-14.2 years). Methods:We retrospectively evaluated 1010 thyroid nodules, with an initial benign cytological diagnosis, that underwent at least one repeat FNAC during the follow-up. Results:The rate of missed cancer in the whole cohort of thyroid nodules was 1.0%, and it increased along by the US risk class (0.8% in very low/low-risk, 1.2% in intermediate-risk, and 3.1% in high-risk nodules). The 2015 ATA US risk stratification system showed a very high accuracy in selecting nodules that did not require a second FNAC (negative predictive value = 99.1%). In addition, the rate of missed cancer significantly increased along with the increase in the US risk class in nodules that showed an enlarged volume (0.4% in the low-risk class and 6.4% in the high-risk class,p = 0.005), while it was very low and not associated with the US features in the subgroup of thyroid nodules that did not grow during the follow-up (p = 0.96). Conclusions:Our results confirm the accuracy of the ATA recommendations in selecting benign nodules for FNAC repetition during the follow-up. An additional cytological evaluation maybe avoided in benign thyroid nodules with low-risk US features, regardless of the evidence of growth during the follow-up. While the utility of the routine repeat FNAC in all benign nodules with high-risk US features remains to be defined, based on our results, repetition of FNAC seems to be indicated in nodules with evidence of growth during the follow-up
Calcitonin Levels in Thyroid Disease Are Not Affected by Autoimmune Thyroiditis or Differentiated Thyroid Carcinoma
No full textIntroduction: Association between hypercalcitoninemia and pathological conditions such as autoimmune thyroiditis (AIT) or differentiated thyroid carcinoma (DTC) has been addressed, with conflicting results. We evaluated the prevalence and the clinical relevance of elevated basal serum calcitonin (CT) levels in non-neoplastic (nodular goiter [NG] and AIT) and neoplastic thyroid diseases (DTC). Methods: We retrospectively evaluated 3,250 consecutive patients with thyroid nodular disease who underwent fine-needle aspiration cytology with adequate sample. After exclusion of medullary thyroid cancer (MTC) patients were divided according to the presence/absence of thyroid autoimmunity into NG or nodular autoimmune thyroiditis (N-AIT) and, according to cytological results, in benign or suspicious/malignant nodules. Results: One hundred ninety-seven/3,250 patients (6.0%) showed CT level >10 pg/mL. In 11/3,250 (0.3%) cases, a final histological diagnosis of MTC was made, while the remaining 186/3,250 patients (5.7%) had non-MTC-related hypercalcitoninemia (CT > 10 pg/mL). According to cytological diagnosis, the rate of hypercalcitoninemia was similar in class II and class V-VI groups (5.4 vs. 6.9%, p = 0.4). The occurrence of hypercalcitoninemia was significantly higher in patients with NG (166/2,634 [6.3%]) than in patients with N-AIT (20/605 [3.3%]) (p = 0.004). However, after matching by sex, no difference was found between the 2 groups (NG and N-AIT). These results were confirmed in 598 patients submitted to surgery. Conclusions: AIT and DTC seem not to affect serum CT levels in patients with thyroid nodules. Therefore, hypercalcitoninemia, in these patients, should be submitted to the same diagnostic workup than patients without AIT or DTC. © 2020 European Thyroid Association Published by S.

Risk of second malignant neoplasm in familial non-medullary thyroid cancer patients
No full textIntroductionSurvival rates in patients with non-medullary thyroid carcinoma (NMTC) are high, increasing the possibility to develop a second malignant neoplasm (SMN). Many studies investigated the relationship between increased risk of SMN in NMTC patients treated with radioiodine, but few data are available about the impact of family history (FH) of thyroid cancer on SMN risk. PurposeTo assess the risk of SMN in a large cohort of sporadic and familial NMTC using the standardized incidence ratio (SIR). Patients and methodsWe studied 918 NMTC patients (73.9% female patients) followed for a median follow-up of 9 years. In 798/918 (86.9%) patients, NMTC was sporadic, while the remaining 120 (13.1%) were familial NMTC (FNMTC). ResultsWe identified 119/918 (13%) patients with SMN in association with NMTC. NMTCs had an increased risk of SMN when compared to the general population (SIR 2.1, 95% CI 1.7-2.5). The rate of SMN for all sites was significantly higher in familial compared to sporadic NMTC (20% versus 11.9%, p = 0.01), primarily driven by families with more than two affected members. The risk of SMN was remarkably higher for breast cancer, especially in familial cases (SIR 22.03, 95% CI 14.4-41.2) compared to sporadic cases (SIR:17, 95% CI 11.9-24.6). ConclusionsNMTC patients have a higher risk of SMN compared to the general population and this risk is much higher in patients with FNMTC. This observation raises the hypothesis that genetic risk factors for a first cancer may predispose to SMN, especially among individuals with familial clustering of the same or other tumors
