Standard therapeutic approaches for benign thyroid lesions that warrant intervention are surgery for cold and either surgery or radioiodine for autonomously functioning thyroid nodules (AFTN). Image-guided thermal ablation (TA) procedures are increasingly proposed as therapy options for selected clinical conditions. Due to mounting scientific evidence and widening availability, ETA considered it appropriate to develop guidelines for the use of TA in adult patients. TA procedures are well tolerated, but a dedicated training of the operators is required and information on possible complications needs to be shared with the patients. The following factors should be considered when weighing between observation, surgery, and TA for benign thyroid nodules. In solid non-hyperfunctioning nodules, TA induces a decrease in thyroid nodule volume, paralleled by improvement in symptoms. Nodule re-growth is possible over time and may necessitate repeat treatment, or surgery, in a dialogue with the patient. In AFTN, radioactive iodine is the first-line treatment, but TA may be considered in young patients with small AFTN due to higher probability of restoring normal thyroid function and avoidance of irradiation. In cystic nodules, ethanol ablation (EA) is the most effective and least expensive treatment. TA may be considered for cystic lesions that relapse after EA or have a significant residual solid component following drainage and EA. TA should be restricted to benign lesions that cause symptoms or cosmetic concern. Presently, laser and radiofrequency ablation are the most thoroughly assessed techniques, with similar satisfactory clinical results. Microwaves and high-intensity focused ultrasound therapy options remain to be fully evaluated.

Objective: To investigate clinical practice regarding the use of selenium supplementation in patients with Hashimoto’s thyroiditis (HT) among members of the European Thyroid Association (ETA). Methods: ETA members were invited to participate in an online survey investigating the use of selenium supplementation across the spectrum of benign thyroid diseases. Of 872 invited members, 242 (28%) completed the survey. After exclusion of basic scientists and non-European members, survey data from 212 respondents were eligible for further analyses. Responses from 65 (31%) individuals who did not at all recommend selenium, or only considered its use in the setting of a clinical trial, were not included in the final analysis of survey data from 147 respondents. ­Results: While only a minority of respondents (29 of 147, 20%) stated that the available evidence warrants the use of Se in patients with HT, a statistically significant majority (95 of 147; 65%, p < 0.001) used Se occasionally or routinely. Se was predominantly recommended for patients with HT not receiving LT4 (102 of 147; 69%) to reduce circulating thyroid autoantibody levels. Very few respondents routinely recommended Se to pregnant patients with HT. Conclusions: A minority of responding ETA members stated that the available evidence warrants the use of Se in HT, but a majority recommended it to some extent, especially to patients not yet receiving LT4. This is questionable, and selenium is not recommended to patients with HT according to current ETA guidelines. Ongoing and future trials may lead to the reversal of current medical practice.

Background: Outcomes of high-intensity focused ultrasound (HIFU), as a non-surgical treatment option for benign symptomatic thyroid nodules, has mainly been based on single-center studies and short-term follow-up. Therefore, we assessed the safety, and long-term efficacy of HIFU in benign thyroid nodules among four centers with expertise in thyroid mini-invasive procedures. Patients and methods: Retrospective three year follow-up study in four European centers, treating solid benign thyroid nodules causing pressure symptoms and/or cosmetic concerns. Nodule volume reduction was assessed at 1, 3, 6, 12, 24, and 36 months post-treatment. Technical efficacy, defined as a volume reduction rate (VVR) >50% was evaluated at 6, 12, 24 and 36 months. Predictive factors of efficacy were assessed using logistic models. Complications and side effects were classified according to the Interventional Radiology Guidelines and changes in local symptoms were scored on a visual-analog scale. Results: Sixty-five patients (mean age 51.1 ± 14.0 years; 86.2% women) with a single thyroid nodule and a mean baseline nodule volume of 9.8 ± 10.3 mL were treated with a mean energy of 7.1 ± 3.1 kJ (range: 2.0 to 15.5 kJ). Median nodule volume reduction was 31.5% (IQR: −38.6% to −23.1%) at 12 months and 31.9% (IQR: −36.4% to −16.1%) at 36 months. Technical efficacy was obtained in 17.2% of cases at 6 months, 17.8% at 12 months, 3.4% at 24 months, and 7.4% at 36 months. The number of treated pixels and the mean energy delivered were positively correlated to VRR at 1, 6 and 12 months. The risk of treatment failure decreased by 4.3% for each additional unit of energy delivered. The procedure duration was inversely correlated with treatment failure (OR 1.043, 95% CI: 1.011–1.083; p = 0.014). Improvement of cervical pressure symptoms or cosmetic complaints were observed in less than 15% of the cases at 12, 24 and 36 months. Horner’s syndrome occurred in one case (1.5%) and minor complications, not requiring treatment, in three (4.6%) patients. No change in thyroid function was registered. Conclusions: HIFU carried a low risk of complications. A single treatment resulted in a 30–35% thyroid nodule volume decrease within one year, reduction that remained stable for 2 years. Outcomes varied significantly between centers with different HIFU expertise. Focus on improved HIFU technology, adequate training, and appropriate selection of patients is needed to achieve efficacy comparable to other thermal ablation procedures.

IntroductionObesity is a global pandemic and is cause of serious concern in all regions of the world. It is important to raise the attention of health care professionals in order to provide early treatment of patients with obesity. Obesity management, however, varies greatly amongst endocrinologists with respect to attitudes to diagnosis and treatment. Aim of this study was to identify practices and needs of Italian endocrinologists with respect to people with obesity.MethodsIn this study, all members of the Italian Association of Clinical Endocrinologists (AME) were invited to participate in a web-based survey concerning the management of obesity.ResultsThe response rate was 24.1% (542/2248). Nutritional and obesity problems were reported as major areas of interest by 29.4% of the participants. A large proportion of patients seeking an endocrine consultation for other reasons are affected by obesity, but one in five respondents addressed the issue in 25% or less of the cases, while one in three always dealt with the problem. Obesity was managed personally/within a dedicated team by 42.6% of participants, while the remainders referred the patient to a dietician/nutritionist or a 2nd level center for obesity therapy. Metformin was used in a median of 30% of the patients (Interquartile range: 10-50) and liraglutide in 10% of the cases (IQR 0-30), while orlistat (median 0%; IQR 0-10) and naltrexone/bupropion (median 0%; IQR 0-5) were seldom prescribed. Cost of therapy was considered as the major limitation to the use of anti-obesity drugs, affecting adherence to long-term treatment. According to 41.9% of respondents, psychological support should be offered to all patients with obesity. Finally, 56% of participants believe that the availability of new drugs will increase the number of patients candidate to drug therapy.DiscussionIn conclusion, it is of primary importance to raise the awareness of endocrinologists towards the problem of obesity and increase their confidence in managing this pathological condition.

BACKGROUND. The standard treatment for hypothyroidism is levothyroxine (LT4), which in the Republic of Belarus is available in tablet form whereas liothyronine (LT3) is not registered, but patients can purchase them on their own abroad. AIM. This study aimed to investigate Belarusian endocrinologists’ attitude of thyroid hormones in hypothyroid and euthyroid patients. MATERIALS AND METHODS. An online survey was conducted, for which members of the Belarusian Medical Association of Endocrinology and Metabolism were invited by posting information in the group chat and by e-mail. The research period was from October 1 to December 26, 2020. 210 questionnaires were received, 146 of which were used. RESULTS. The majority of participants, 145 (99.3%), indicated that they were using LT4 as the first-choice drug for the treatment hypothyroidism. Sixty-one (41.8%) doctors answered that LT3 + LT4 combination likely can be used in patients with long-term untreated hypothyroidism and 15 (10.3%) — in patients with persistent symptoms of hypothyroidism, despite biochemical euthyroidism on therapy LT4. Over half of the respondents 84 (57.5%) answered that thyroid hormone therapy was never indicated for euthyroid patients, but 50 (34.2%) would consider it for female infertility with high level of thyroid antibodies and 36 (24.7%) for simple goiter growing over time. In various conditions that could interfere with absorption of LT4, most responding Belarusian endocrinologists do not expect a significant difference with different formulations (tablets + “I do not expect major changes in different forms” vs. “soft gel capsules” + “liquid solution”; p

Objective To identify the attitudes of German thyroid specialists towards the clinical treatment of hypothyroidism using thyroid hormones (TH). Methods All members of the thyroid section of the German Endocrine Society (DGE) were e-mailed an invitation to participate in a web-based survey about substitution with TH. Results Out of 206 members of the DGE’s thyroid section, 163 (79.1%) responses were received and included in the analysis. Of responding members, 98.6% used levothyroxine (LT4) as the treatment of choice, and 45.4% also prescribed combination therapy with liothyronine (LT4+LT3) in their clinical practice (p Conclusion For German thyroid specialists, LT4 is the treatment of choice for hypothyroidism. Combination therapy with LT4+LT3 was considered for patients with persistent symptoms. Even in conditions that could affect bioavailability, German thyroid specialists prefer LT4 tablets rather than other LT4 formulations, such as liquid or soft-gel capsules. The widespread use of thyroid hormone for non-hypothyroid conditions is not consistent with current evidence and needs further study.

Objective: The first edition of the American Association of Clinical Endocrinology/American College of Endocrinology/Associazione Medici Endocrinologi Guidelines for the Diagnosis and Management of Thyroid Nodules was published in 2006 and updated in 2010 and 2016. The American Association of Clinical Endocrinology/American College of Endocrinology/Associazione Medici Endocrinologi multidisciplinary thyroid nodules task force was charged with developing a novel interactive electronic algorithmic tool to evaluate thyroid nodules. Methods: The Thyroid Nodule App (termed TNAPP) was based on the updated 2016 clinical practice guideline recommendations while incorporating recent scientific evidence and avoiding unnecessary diagnostic procedures and surgical overtreatment. This manuscript describes the algorithmic tool development, its data requirements, and its basis for decision making. It provides links to the web-based algorithmic tool and a tutorial. Results: TNAPP and TI-RADS were cross-checked on 95 thyroid nodules with histology-proven diagnoses. Conclusion: TNAPP is a novel interactive web-based tool that uses clinical, imaging, cytologic, and molecular marker data to guide clinical decision making to evaluate and manage thyroid nodules. It may be used as a heuristic tool for evaluating and managing patients with thyroid nodules. It can be adapted to create registries for solo practices, large multispecialty delivery systems, regional and national databases, and research consortiums. Prospective studies are underway to validate TNAPP to determine how it compares with other ultrasound-based classification systems and whether it can improve the care of patients with clinically significant thyroid nodules while reducing the substantial burden incurred by those who do not benefit from further evaluation and treatment.

Összefoglaló. Bevezetés: A pajzsmirigy-alulműködés gyakori betegség. Kezelésében a levotiroxin (LT4)-pótlás a szokásos eljárás, mely tabletta vagy gélkapszula formájában áll rendelkezésre Magyarországon. A nemzetközi trendeknek megfelelően az esetek korai felismerése miatt már a kevésbé kifejezett hormonális eltérések idején elindul a kezelés. Az endokrinológusok hypothyreosiskezelési szokásaival kapcsolatban Magyarországon és Európában felmérés eddig nem történt. Célkitűzés: A THESIS (Treatment of Hypothyroidism in Europe by Specialists: an International Survey) célja, hogy felmérjük az európai és közte jelen munkánkban a magyar endokrinológusok hypothyreosiskezelési szokásait és az LT4 esetleges alkalmazását pajzsmirigy-működészavarral nem járó állapotokban. Módszer: A Magyar Endokrinológiai és Anyagcsere Társaság (MEAT) tagjainak e-mailben meghívót küldtünk az online kérdőíves vizsgálathoz. Eredmények: 165 magyar endokrinológus válaszai alapján végeztük az elemzést. A válaszadók többsége, 99,4%-uk első kezelésként LT4-pótlást alkalmaz. Az LT4 + LT3 kombinációt elsősorban olyan betegeknél alkalmazzák, akik LT4 szedése mellett euthyreoid hormonértékek ellenére hypothyreosisra jellemző tüneteket mutatnak (36,1%). Euthyreoid hormonértékek mellett, magas antitestszint és infertilitás esetén 60,3% megfontolná LT4 indítását, amit evidenciák jelenleg nem indokolnak. Számos kórállapot befolyásolja az LT4 felszívódását, ezekben az esetekben a magyar endokrinológusok 66,4%-a preferálja a lágy kapszula alkalmazását, jobb eredményt várva a gyógyszerformák közötti váltástól. Következtetés: A pajzsmirigy-alulműködés kezelésében a magyar endokrinológusok elsődlegesen az LT4-et választják. Az LT4 + LT3 kombinált alkalmazását a pajzsmirigy-stimuláló hormon normális szintjének elérése után perzisztáló hypothyreosisos tünetek esetén fontolják meg. Az újabb gyógyszerformákat a többség preferálja, ha az LT4 hagyományos tablettás formájának alacsonyabb biohasznosulása várható. Orv Hetil. 2022; 163(12): 463-472.Hypothyroidism has a high prevalence in the adult population. Levothyroxine (LT4) supplementation is considered to be the gold-standard treatment method. In Hungary, LT4 tablets and soft gel capsules are the available formulations. Similarly to the international trends, hypothyroidism is earlier recognised, leading to early LT4 supplementation. Up till now, there has been no survey on the treatment of hypothyroidism among Hungarian endocrinologists.THESIS (Treatment of Hypothyroidism in Europe by Specialists: an International Survey) had been conducted to assess treatment preferences among European endocrinologists. Here we report the results on the use of thyroid hormones in hypothyroid patients and euthyroid individuals in Hungary.An e-mail invitation to participate, containing the link to the online survey was sent to members of the Hungarian Society for Endocrinology and Metabolism.There were 165 responses with full demographics which were included in the analysis. By the majority (99.4%) of them, LT4 was the first treatment of choice. LT4 + LT3 combination was considered an option in patients with persistent symptoms despite biochemical euthyroidism while on LT4 (36,1%). In euthyroid individuals, 60.3% of the respondents would consider starting LT4 in euthyroid infertile women with high antibody levels, which is hardly supported by evidence. In the presence of comorbidities and interfering medications which may hinder LT4 absorption, 66.4% of Hungarian endocrinologist anticipate significant improvement after switching from tablets to soft gel capsules.The treatment of choice for hypothyroidism is LT4 in Hungary. Combination therapy with LT4 + LT3 was considered for patients with persistent symptoms. In the presence of diseases and interfering medications affecting bioavailability, a high number of Hungarian endocrinologists prefer the new LT4 formulation. The administration of LT4 in euthyroid conditions awaits explanation and calls for intensive discussions at local conferences and courses. Orv Hetil. 2022; 163(12): 463-472.

Purpose: To investigate current practices of specialists in the use of thyroid hormone preparations in Greece as part of an ongoing international survey, namely THESIS—Treatment of Hypothyroidism in Europe by Specialists: an International Survey. Methods: An electronic link leading to an anonymized questionnaire was sent to all (n = 837) members of the Hellenic Endocrine Society. Results: In total, 501 respondents participated in the survey, though only part of the questionnaire was filled in by some participants. A total of 88.2% were endocrinologists and 57.9% worked in private practice. Levothyroxine (LT4) was the first-line choice (98.6%) for the treatment of hypothyroid patients. In total, 70.2% preferred LT4 soft-gel capsules for patients reporting intolerance to various foods. Soft-gel capsules were the preferred LT4 formulation for patients on generic LT4 and with unexplained poor biochemical control of hypothyroidism (66.3%) or inability to take LT4 fasted and separate from food/drink (68.3%). It was found that 48.4% would never use combined LT4 + LT3. However, 25% would use combination therapy for a short period in patients recovering from protracted hypothyroidism or in patients with normal serum TSH but persistent symptoms. Concerning euthyroid individuals, 31.9% considered treatment with thyroid hormones in infertile females with positive thyroid antibodies and 24.4% in patients with growing goiter. Selenium or iodine supplementation was used occasionally, mostly in patients with coexisting autoimmune thyroiditis. Conclusions: LT4 tablets are the treatment of choice for hypothyroidism in Greece. Several conditions may lead to various other practices, some of which deviate from current evidence-based guidelines and need more scrutiny.

The growing detection of papillary thyroid microcarcinomas (PTMCs) is paralleled by an increase in surgical procedures. Due to the frequent indolent nature, cost, and risk of surgery, active surveillance (AS) and ultrasound-guided minimally invasive treatments (MITs) are in suitable cases of incidental PTMC proposed as alternatives to thyroidectomy. Surgery and radioiodine are the established treatments for relapsing cervical differentiated thyroid carcinoma (DTC) metastases. But radioiodine refractoriness, risk of surgical complications, adverse influence on quality of life, or declining repeat surgery have led to AS and MIT being considered as alternatives for slow-growing DTC nodal metastases. Also, for distant radioiodine-refractory metastases not amenable to surgery, MIT is proposed as part of a multimodality therapeutic approach. The European Thyroid Association and the Cardiovascular and Interventional Radiological Society of Europe commissioned these guidelines for the appropriate use of MIT. Based on a systematic PubMed search, an evidence-based approach was applied, and both knowledge and practical experience of the panelists were incorporated to develop the manuscript and the specific recommendations. We recommend that when weighing between surgery, radioiodine, AS, or MIT for DTC, a multidisciplinary team including members with expertise in interventional radiology assess the demographic, clinical, histological, and imaging characteristics for appropriate selection of patients eligible for MIT. Consider TA in low-risk PTMC patients who are at surgical risk, have short life expectancy, relevant comorbidities, or are unwilling to undergo surgery or AS. As laser ablation, radiofrequency ablation, and microwave ablation are similarly safe and effective thermal ablation (TA) techniques, the choice should be based on the specific competences and resources of the centers. Use of ethanol ablation and high-intensity focused ultrasound is not recommended for PTMC treatment. Consider MIT as an alternative to surgical neck dissection in patients with radioiodine refractory cervical recurrences who are at surgical risk or decline further surgery. Factors that favor MIT are previous neck dissection, presence of surgical complications, small size metastases, and

Background: Image-guided tumor ablation is commonly performed in clinical practice. Trying to standardize terminology and data collection to enable a more reliable comparison among the different studies, in 2003, a document entitled "Image-Guided Tumor Ablation: Proposal for Standardization of Terms and Reporting Criteria" was published by the International Working Group on Image-Guided Tumor Ablation. Since then, ablations have evolved significantly, with the development of new technology and techniques and applications. This has included benign thyroid nodules, and their ablation has become increasingly accessible, not only among radiologists but also among other specialists involved in thyroid care, including endocrinologists and surgeons. This has resulted in further inhomogeneity in how data are presented and reported among different studies, resulting in a need for standardization to homogenize language and data reporting on the topic. Summary: In February 2018 in Milano, Italy, a meeting involving specialists concerned with minimally invasive treatments of thyroid lesions was organized, and the Italian Working Group on Minimally Invasive Treatments of the Thyroid was founded with the aim of establishing a collaborative network among all clinicians working in this field. The first work of this group is to present a proposal for standardization of terminology and reporting criteria on image-guided ablations to treat benign thyroid nodules. Conclusion: This proposal was drafted with the goal of providing guidance for standardized reporting of results in studies regarding image-guided thyroid ablations. We encourage adoption of this terminology worldwide, anticipating that this will facilitate improved communication and understanding within the field and stimulate further discussion on the topic over the next years.

A significant minority of patients with hypothyroidism report persistent symptoms despite achieving normal thyroid biochemistry after levothyroxine (L-T4) replacement. Four principal lines of thinking, which are not mutually exclusive, may explain this enigma. The 'low tissue liothyronine hypothesis' emphasizes the potential imperfections of L-T4 replacement therapy that may lead to hypothyroidism in some tissues such as the brain, while others (eg hypothalamus) are euthyroid. The 'Somatic Symptom and Related Disorders hypothesis' draws attention to an incidental coexistence of a diagnosis of Somatic Symptom and Related Disorders in patients with treated hypothyroidism. The 'autoimmune neuroinflammation hypothesis' highlights the potential consequences of inflammatory mediators due to thyroid autoimmunity (the commonest cause of hypothyroidism) on the brain. The 'comorbidities and psychosocial hypothesis' implicates a variety of physical and psychosocial factors that have been noted to be associated with a diagnosis of hypothyroidism, which may be primarily the cause of persistent complaints. Over the past twenty years, a great deal of time and effort has been expended pursuing the 'low tissue liothyronine hypothesis', which has failed to yield results that translate to patient benefits. This has skewed the balance in clinical practice, in favour of pursuing answers relating to L-T4 and liothyronine combination treatment, while the alternative explanations have been downplayed and potentially useful interventions have been given insufficient attention.

Objectif Identifier les habitudes de prescriptions d’hormones thyroidiennes par les medecins de la Societe Francaise d’Endocrinologie (SFE), en tenant compte des formulations disponibles de levothyroxine. Materiel et methodes Les medecins de la SFE ont ete invites entre janvier et avril 2021 a remplir un questionnaire en ligne concernant leurs habitudes de prescription d’hormones thyroidiennes. Resultats Parmi 2094 membres, 535 (25,5 %) ont pu etre inclus dans l’analyse. La levothyroxine (LT4) est le traitement de choix de l’hypothyroidie (99,4 % des repondants), essentiellement sous forme de comprimes. 7,1 % et 14,2 % des repondants envisagent de prescrire de la liothyronine (LT3) ou une combinaison LT3/LT4 dans certaines circonstances, principalement en cas de persistance de symptomes d’hypothyroidie malgre une TSH normale avec LT4. Concernant la prescription d’hormones thyroidiennes chez des patients euthyroidiens, 40,4 % affirment qu’elles ne sont jamais indiquees dans ce cas et 37 % pourraient les prescrire en cas de goitre dont le volume augmente. Une part significative des repondants (29–56 %) n’attend pas de changement majeur avec d’autres formulations de LT4 (capsule molle ou gouttes), meme en cas de difficulte d’equilibration ou de suspicion de malabsorption. Conclusion Le traitement de choix de l’hypothyroidie en France est la LT4, sous forme de comprimes. Une minorite envisage les preparations a base de LT3 en cas de symptomes persistants avec TSH normale. Certains envisagent la prescription d’hormones thyroidiennes chez des patients en euthyroidie avec un goitre dont le volume augmente. Les resultats de cette enquete menee dans d’autres pays europeens seront compares secondairement.

Background: Levothyroxine (LT4) as a medication is used by up to 5.3% of the adult population. For optimal efficacy, the traditional tablet formulation (LT4tab) requires that patients avoid concomitant ingestion with food, drinks, and certain medications, as well as excellent patient compliance. Some comorbidities influence bioavailability of LT4 and may mandate repeated dose adjustments. Summary: New LT4 formulations (soft gel [LT4soft] and liquid [LT4liq]) containing predissolved LT4 are claimed to improve bioavailability, presumably by facilitating absorption. Thus, these formulations may well be more suitable than LT4tab for patients whose daily requirements are subjected to variations in bioavailability. Here, we review the evidence and indications for use of new LT4 formulations and highlight areas of uncertainty that are worthy of further investigation. While bioequivalence is established for LT4soft and LT4liq administered to healthy volunteers compared with LT4tab in pharmacokinetic (PK) studies, therapeutic equivalence of the new formulations seems to be different in several clinical settings. Some evidence suggests that new formulations of LT4 may mitigate against the strict requirements relating to concomitant ingestion with food, drinks, and certain medications, which apply to traditional LT4 tablets. The principal indication is in selected patients with disease fluctuations and intermittent therapies with interfering medications, where the need for frequent dose adjustments and office visits may be diminished. Whether the use of LT4soft or LT4liq in patients with impaired gastric acid secretion results in better control of hypothyroidism than LT4tab remains unclear. Conclusions: The evidence in favor of using LT4soft and LT4liq in clinical practice over LT4tab is weak, and the underlying putative PK mechanisms unclear. Additional studies to investigate these potential benefits, define the cost-effectiveness, and understand the PK mechanisms involved with new LT4 formulations are needed.

Background. Direct loco-regional treatments are considered for local control of cervical metastasis of thyroid cancer. In our feasibility study, laser ablation was employed for initial debulking of an unresectable radioiodine-refractory thyroid cancer in a combined treatment with tyrosin kinase inhibitors (TKI). Clinical case. On June 2016, a 69-year-old woman underwent partial resection of a papillary thyroid cancer with extensive tracheal infiltration. On August 2016, whole body scan performed after 131-I treatment (8140 MBq) demonstrated nearly absent thyroid bed uptake. Due to progressive increase of the cervical mass, the patient experienced dysphonia and dysphagia and, after multidisciplinary consultation, was treated with laser ablation (LTA). After local anesthesia, two 300 nm fiberoptics were inserted into the lesion through 21G spinal needles. Two illuminations with 4-watt output power and 3600 Joules energy delivery were peformed with a diode-laser source. LTA resulted in rapid mass volume decrease (28 x12 x16 mm, 2.8 mL, vs 52 x 29 x 29 mm, 22.7 mL) and improvement of pressure symptoms that lasted 6 months. In May 2017, due to initial regrowth of the tumor mass, the patient started therapy with Lenvatinib, at 10-24 mg/day. The cervical tumor burden remained controlled until April 2019, when occurred rapid disease progression and death of the patient. Discussion. These preliminary results suggest that locally-advanced unresectable and radioiodine-refractory thyroid tumors can be managed with preliminary LTA mass debulking, for rapid control of local disease, followed by long-term TKI treatment.

Background: Single-center trials demonstrated moderate-substantial level of interobserver agreement in the evaluation of ultrasound (US) features of thyroid nodules. Multicenter studies on US agreement, however, are scanty, and data on intraobserver agreement are poor. Aim of the study was to assess inter- and intraobserver agreement between different thyroid centers and different specialists. Methods: A blinded analysis of 100 electronically recorded thyroid nodule US images was conducted in three large-volume thyroid centers by seven radiologists and endocrinologists. The evaluation was repeated after randomization 4 months later. The following US characteristics were evaluated: composition, echogenicity, margins, intranodular echogenic spots, vascularity, and shape. Thyroid nodules were also classified according to AACE/ACE/AME, EU-TIRADS, ATA, and ACR-TIRADS US classifications. Intra- and interobserver agreement was calculated using cross-tabulation expressed as mean Cohen's Kappa. Results: Interobserver agreement for US features: K-coefficient was 0.53 for composition, 0.47 for echogenicity, 0.46 for intranodular vascularity, and 0.33 for margins of the nodules. For echogenic foci, the K-coefficient was 0.47 for microcalcifications, 0.38 for macrocalcifications, 0.11 for the subcategory comet-tail artifacts, and 0.42 for shape. Operators resulted uncertain on hyperechoic foci definition in 16% of cases and described them as "hyperechoic foci of uncertain significance." Interobserver Cohen-K for US classification systems was 0.44 for AACE, 0.42 for ACR-TIRADS, 0.39 EU-TIRADS, and 0.34 for ATA. Intraobserver agreement: the K-coefficient for nodule US features was 0.62 for intranodular vascularity, 0.58 for composition, 0.60 for echogenicity, 0.54 for macrocalcifications, 0.55 for microcalcifications, 0.47 for comet tails, 0.39 for margins, and 0.35 for shape. Intraobserver Cohen-K for US classification systems was 0.54 for AACE, 0.49 for ACR-TIRADS, 0.38 for ATA, and 0.33 for EU-TIRADS. Conclusions: Intraobserver reproducibility for thyroid nodule US reporting and US classification systems appears fairly adequate, while the interobserver agreement between different centers is lower than that assessed in single-center trials. Reporting and rating ability of thyroid US examiners still appear not consistent. An unified lexicon of thyroid US features, a simplified method of classification, and a dedicated training in the description of thyroid US findings may increase the observers' agreement and the predictive value of US classification systems in real world practice.

To assess the efficacy, safety, and pain benefits of imaging-guided laser ablation (IGLA) in patients with radioiodine-refractory (RR) bone metastases from differentiated thyroid carcinoma (DTC). The institutional medical records of patients with bone metastases from DTC treated with laser ablation (LA) were reviewed retrospectively. Local response, complications, and effects on pain relief were investigated. Six osteolytic lesions in five patients (one male, four females; mean age 65.4 ± 5.1 years, range 58–72) were treated with IGLA. All lesions were osteolytic and all have had previous treatments with high-dose radioiodine therapy followed by external radiotherapy (EBRT). All patients assumed opioid analgesics for severe pain. Overall, the lesions (mean size 5.8 ± 3.2 cm; median 5.0 cm, range 3.0–12.0 cm) underwent nine IGLA sessions (mean 1.8 ± 0.4 sessions; median 2.0 sessions, range 1–2). In four (80%) out five lesions, cross-sectional imaging showed a nearly complete response (CR) while the largest lesion was ablated by 80%. Pain changes were assessed with the Brief Pain Inventory-Short Form, that was administered before IGLA and during a 6-month follow-up. Patients experienced significant reduction in worst pain, average pain, and pain interference. Following IGLA, the average daily opioid requirement rapidly and progressively decreased. Treatments were well-tolerated and no major complications occurred. IGLA is an effective and safe debulking procedure and provides significant pain relief in patients suffering from DTC bone metastases that are not responsive to standard treatments. So, IGLA could be considered as part of a multimodality management of advanced thyroid cancer with RR metastatic skeletal involvement.

Objective. Romania has no national guidelines for hypothyroidism treatment, nor are there any recommendations from national societies to adhere to international guidelines. Our aim was to identify the attitudes of Romanian physicians relating to hypothyroidism treatment focusing on available formulations of levothyroxine (LT4). Methods. All 748 members of the Romanian Society of Endocrinology were invited to participate in a web-based survey. A total of 316 (42.24%) members responded, of whom 222 (70.2%) completed all questions. Results. Half of the respondents recommended LT4 treatment in euthyroid patients, from 3.6% in euthyroid patients with obesity to 36.4% in euthyroid females with infertility associated with high levels of thyroid antibodies. LT4 was considered the preferred treatment for hypothyroidism (compared to combination treatment of LT4 with LT3 or LT3 alone) by 98.6% of respondents. LT4 in liquid solution was preferred over tablets if malabsorption is suspected (56.5% vs. 27.3%), for patients with unexplained poor biochemical control (52.5% vs. 22.9%) and for patients not able to adhere to ingesting LT4 fasted (74.0% vs. 9.8%). The most and least probable explanations for persistent symptoms in patients with hypothyroidism who achieve a normal TSH under medication were “psychosocial factors” and “burden of having to take medication”, respectively. Conclusion. A significant proportion of Romanian physicians would use LT4 in some groups of euthyroid patients, contrary to current evidence. The preferred treatment for hypothyroidism was LT4. Alternative LT4 formulations (liquid solution) are considered in specific clinical conditions. Diversification of available thyroid hormone formulations was readily incorporated into everyday practice.

Background: The incidence and prevalence of hypothyroidism are increasing and the threshold for the treatment of hypothyroid as well as individuals without evident thyroid disease with thyroid hormone is declining. Objective: To investigate endocrinologists' use of thyroid hormones in hypothyroid and euthyroid patients in Italy, a country where different formulations of levothyroxine (LT4; tablet, liquid solution and soft-gel capsule) are available on the market. Methods: Members of the Associazione Medici Endocrinologi (Italian Association of Clinical Endocrinologists) were invited to participate in a web-based survey investigating the topic. Results: A total of 797 of 2,028 (39.3%) members completed all the sections of the survey; 98.7% declared that the treatment of choice for hypothyroidism is LT4. A significant minority (37.3%) indicated that LT4 may be considered in infertile euthyroid women seeking pregnancy and harbouring positive thyroperoxidase antibodies (TPOAb) and in goitre increasing in size (18.1%). LT4 + LT3 was considered by 43.2% for LT4-replaced patients and normal TSH, if they reported persistent symptoms. High percentages of respondents chose LT4 in a liquid solution or soft-gel capsules when taken together with other drugs interfering with LT4 absorption (81.8%), in patients with a history of celiac disease, malabsorption, lactose intolerance, intolerance to common excipients (96.6%), or unexplained poor biochemical control of hypothyroidism (74.4%), or in patients not able to adhere to ingesting LT4 fasted and/or separated from food/drink (98.9%). In total, 43.6% of responders would use LT4 in a liquid solution or soft-gel capsules for hypothyroid patients with biochemical euthyroidism on LT4, who had persistent symptoms. Conclusions: The preferred treatment for hypothyroidism is LT4; LT3 + LT4 combination treatment is mainly considered in patients with persistent symptoms. A significant minority would offer LT4 to euthyroid women with positive TPOAb and infertility and to euthyroid patients with progressive simple goitre. Alternative LT4 formulations like liquid solution or soft-gel capsules are largely reserved for specific conditions (interfering drugs, actual or suspected malabsorption, inability to take LT4 in the fasting state, unexplained poor biochemical control of hypothyroidism).

Radiofrequency and laser ablation (RFA and LA) are effective treatments for benign thyroid nodules. Due to their relatively recent introduction into clinical practice, there are limited long-term follow-up studies. This study aimed to evaluate technique efficacy, rate of regrowth and retreatment over 5 years following RFA or LA and to identify predictive factors of outcome.

To perform an online survey about the use of Thyroid Imaging Reporting and Data System (TIRADS) classification in Italy. An online questionnaire was administered to all members of the Italian Society of Medical and Interventional Radiology (Societa Italiana di Radiologia Medica ed Interventistica, SIRM) and Italian Society of Ultrasound in Medicine and Biology (Societa Italiana di Ultrasonologia in Medicina e Biologia, SIUMB). The survey consisted of 14 questions about demographics, knowledge, and the use of TIRADS classification, current job, expertize in thyroid ultrasound and fine needle aspiration biopsy, and work environment. Descriptive and nonparametric statistics were used, with P

Background: Until recently, treatment of hypothyroidism has been accomplished using monotherapy of synthetic L-thyroxine (L-T4) sodium tablets that should be taken 30-60 minutes before breakfast. Nowadays, a liquid preparation of levothyroxine is available and can effectively replace tablets without the need of waiting before having breakfast. Evidence of Quality of life (QoL) improvement when shifting from the former to the latter preparation, however, is still lacking. Objective: The study aimed to assess changes in QoL of hypothyroid patients dissatisfied with their therapy with L-T4 sodium tablets who were switched from tablets taken 30-60 minutes before breakfast to liquid L-T4 at breakfast. Methods: A total of 418 consecutive hypothyroid subjects treated by means of L-T4 tablets were asked about their satisfaction/dissatisfaction in order to take the medication 30-60 minutes before having breakfast. Overall, 110 patients (26.3%) complained of the timing of their L-T4 therapy (30-60 minutes before breakfast). A dedicated QoL questionnaire (ThyTSQ), taking just a few minutes to be filled in was then administered to these dissatisfied patients. They were therefore switched to L-T4 to be taken at breakfast. Aiming to avoid TSH elevation due to L-T4 tablets malabsorption caused by meal interference and gastric pH changes, patients were invited to take L-T4 liquid form, as this is claimed to be scarcely affected by the non-fasting state. The questionnaire (ThyTSQ) was administered again at the control visit 3 months later. TSH, FT4, FT3 serum concentrations and metabolic parameters were also recorded. Results: An improved QoL, mainly due to an easier adherence to treatment, was reported by 66.6% of 102 patients who completed the study after shifting from taking medication 30-60 minutes before breakfast to at breakfast ingestion (P 2mIU/L Conclusion: In hypothyroid subjects dissatisfied with L-T4 tablets ingested 30-60 minutes before breakfast, the shift to the same dose of L-T4 in liquid form taken at breakfast improved QoL in the majority of patients, without affecting thyroid function.

Background Conventional tools for medical education are burdened by many drawbacks. Textbooks become rapidly outdated, meeting attendance is expensive, and results reported in journals are not easily suitable for clinical practice. Uptodate and Endotext are excellent online tools, but they have been developed for a clinical context far different from that of our country. Methodology Italian Association of Clinical Endocrinologists (AME) charged a task force aiming to develop an educational tool specifically tailored for Italian clinical endocrinologists. Required characteristics were clinical approach, modularity, continuous updating, full online availability (even by mobile devices), open sections and sections for registered members only, opportunity for individualization, indexing and search engine to facilitate browsing. Starting from an open-source platform, Joomla, several changes were implemented. Results Three editors, 2 central editorial secretaries, 30 section coordinators and over 350 authors have been involved in the writing of 21 different sections covering all fields of endocrine and metabolic diseases. The access to Endowiki is free for AME members and is fully open in sections for patients. All readers are requested to serve as referee, pointing to mistakes and need for revision. The system is attended daily by a mean of 250 individuals. Conclusions Endowiki stands alone as an opportunity for medical education in Italy. The big challenges will be the continuous updating and the link to the national certified system for CME.

OBJECTIVES: Pregnancy induces changes in thyroid function, and thyroid dysfunction during gestation is associated with adverse outcomes. We examined the management of subclinical hypothyroidism and chronic autoimmune thyroiditis in pregnancy among Italian and Romanian endocrinologists. METHODS: Members of the Associazione Medici Endocrinologi (AME) and Romanian Society of Endocrinology (RSE) were invited to participate in a web-based survey investigating the topic. RESULTS: A total of 902 individuals participated in the survey, 759 of whom completed all sections. Among the respondents, 85.1% were aware of the 2017 American Thyroid Association guidelines about thyroid disease and pregnancy, and 82.9% declared that thyroid-stimulating hormone (TSH) screening at the beginning of pregnancy should be warranted. In a patient negative for peroxidase antibodies, 53.6% considered 2.5 mIU/L and 26.2% considered 4.0 mIU/L as the upper normal limit of TSH, and 50% would treat a patient with TSH 3.5 mIU/L with levothyroxine. About 20% did not suggest iodine supplementation. Isolated hypothyroxinemia detected in the first trimester would be treated by 40.8%. In patients undergoing ovarian stimulation, a TSH < 2.5 mIU/L would be targeted by 70%. CONCLUSIONS: Respondents globally appeared well informed about the management of thyroid autoimmunity and subclinical hypothyroidism in pregnancy. A more aggressive attitude in implementing iodine supplementation would be desirable. Most endocrinologists were convinced about an evident association between mild thyroid impairment and adverse outcomes in pregnancy, thus using a TSH value of 2.5 mIU/L as the threshold for diagnosing hypothyroidism and starting levothyroxine in pregnant women.

To compare technique efficacy and safety of laser ablation (LA) and radiofrequency ablation (RFA) in treatment of benign thyroid nodules.Institutional review board approval was obtained, and patients' consent was waived. 601 nodules were treated from May 2009 to December 2014 at eight centres, 449 (309 females, age 57 ± 14 years) with LA and 152 (107 females, age 57 ± 14 years) with RFA. A matched cohort composed of 138 patients from each group was selected after adjustment with propensity score matching. Factors influencing volume reduction at 6 and 12 months and complications were evaluated.No significant differences were observed in the baseline characteristics between groups after propensity score matching adjustment. Mean nodule reduction at 6 and 12 months was -67 ± 19% vs. -57 ± 21% (p 0.001) - 70 ± 19% vs. -62 ± 22% (p = 0.001) in LA group and in RFA group, respectively. Nodules with volume 30 mL had significantly higher percentage volume reduction at 6 and 12 months (-69 ± 19 vs. -50 ± 21, p = 0.001) and (-73 ± 18 vs. -54 ± 23 8, p = 0.001) in the LA group than in the RFA group, respectively. In both groups, operator's skills affected the results. Major complications occurred in 4 cases in each group (p = 0.116) Conclusions: LA and RFA showed nearly similar outcome but LA was slightly more effective than RFA in large nodules. Operator's skills could be crucial in determining the extent of nodule volume reduction regardless of the used technique.

Background: While thyroid nodules are frequent in endocrine clinical practice, patients are often asymptomatic and euthyroid, and death is rare in cases of malignancy. Objectives: To evaluate the perception of current international guidelines regarding thyroid nodule management among Italian endocrinologists, and to compare daily clinical practice with suggested recommendations. Methods: Italian Association of Clinical Endocrinologists (AME) members were invited to participate in a Web-based survey. Results: A total of 566 physicians responded. About 50% had read the full text of the guidelines. Over half appreciated the suggested ultrasound (US) risk categories. Fine-needle aspiration (FNA) was obtained more frequently than recommended. Follow-up of a cytologically benign nodule was largely performed according to the guidelines. Molecular testing would be most commonly requested when cytology reports showed atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) (TIR3A for Italian System). Iodine and/or levothyroxine were largely prescribed for cytologically benign asymptomatic nodules. Laser/radiofrequency ablation and percutaneous ethanol injection were commonly considered as alternatives to surgery (46.2 and 71.4%, respectively). Conclusions: Efforts are needed to make the guidelines more user-friendly and to encourage the use of codified risk categories in thyroid US reports. FNA indications remain a matter of debate as FNA is obtained in clinical practice more often than is recommended. Current US follow-up modalities for a benign nodule are correct, but probably could be performed less frequently without any harm. Molecular testing, if accessible, would be helpful in guiding clinicians' strategies in cases of AUS/FLUS-TIR3A cytologic results. Nonsurgical procedures are favorably embraced.

Surgery is the traditional treatment for thyroid nodules that keep growing over time and are associated with local symptoms. Yet, the direct and indirect expenses due to thyroidectomy and its long-term consequences, the risk of temporary or permanent complications, and the potential adverse influence on the quality of life are important concerns. Due to these considerations, a few image-guided minimally invasive procedures have been proposed for an office-based treatment of nodules that even if benign thyroid nodules are symptomatic or cause cosmetic concern. Among these techniques, US-guided laser thermal ablation (LA) is the most thoroughly assessed and is currently an easy accessible procedure in several thyroid specialized centers in Europe and Asia.

Background: Single-center trials have demonstrated an acceptable level of inter-observer agreement in the evaluation of the ultrasound (US) features of thyroid nodules, but limited data are available about the consistency in the assessment of US findings among different thyroid centers. Aim of the study: to assess the inter-observer agreement between different thyroid centers and among different specialists in the evaluation of the main US features of thyroid nodules. Materials and methods A blinded retrospective analysis of 100 electronically-recorded US images was conducted in three large-volume thyroid centers by seven qualified thyroid imaging experts, two radiologist and five endocrinologists. The following US features were evaluated: composition (solid, predominantly solid, predominantly cystic, and cystic); echogenicity (hyperechoic, isoechoic, mildly and deeply hypoechoic); margins (well-defined, ill-defined, microlobulated, and spiculated); calcifications (absent, microscopic, macroscopic, eggshell); hyperechoic foci of uncertain significance; comet-tail artifacts; vascularity (no vascular signals, perinodular and/or slight intranodular flow, and marked intranodular flow). Thyroid nodules were also classified according to four major US classification systems: AACE/ACE/AME, EU-TIRADS, ATA and ACR. The inter-observer agreement was calculated using cross-tabulation expressed in Cohen's Kappa. Kappa values were evaluated, according to Landis and Koch, as follows: 0-0.20 poor, 0.21-0.40 fair, 0.41-0.60 moderate, 0.61-0.80 substantial, and 0.81-1.0 almost perfect agreement. A sub-analysis assessed how many times and how many operators evaluated as suspicious for malignancy the US features of each nodule. Results: The inter-observer agreement resulted in a K-correlation coefficient of 34.5%, 44.0%, 42.3% and 38.8% for the ATA, AACE/ACE/AME, ACR, and EU-TIRADS classification systems, respectively. The interobserver agreement for the main thyroid nodule US findings resulted as follows: composition 53.2%; echogenicity 46.9%; margins 33.2%; comet-tail 10.6%, microcalcifications 46.8%; macrocalcifications 37.7%; eggshell calcifications 64.9%; intranodular vascularity 45.9%. Conclusion: The level of agreement among different thyroid centers in the description of suspicious US features in thyroid nodules ranged from fair to moderate, with the lowest level of consistency for the characteristics of margins and the presence of comet-tails. A similar range of variability was demonstrated also for the four US classification systems. An universally accepted lexicon of thyroid US features and a dedicated training in thyroid US findings definition are needed to improve the inter-observer agreement and the predictive value of US classification systems in real world practice.

Benign thyroid nodules are a common clinical occurrence and usually do not require treatment unless symptomatic. During the last years, ultrasound-guided minimally invasive treatments (MIT) gained an increasing role in the management of nodules causing local symptoms. In February 2018, the Italian MIT Thyroid Group was founded to create a permanent cooperation between Italian and international physicians dedicated to clinical research and assistance on MIT for thyroid nodules. The group drafted this list of statements based on literature review and consensus opinion of interdisciplinary experts to facilitate the diffusion and the appropriate use of MIT of thyroid nodules in clinical practice. (#1) Predominantly cystic/cystic symptomatic nodules should first undergo US-guided aspiration; ethanol injection should be performed if relapsing (level of evidence [LoE]: ethanol is superior to simple aspiration = 2); (#2) In symptomatic cystic nodules, thermal ablation is an option when symptoms persist after ethanol ablation (LoE = 4); (#3) Double cytological benignity confirmation is needed before thermal ablation (LoE = 2); (#4) Single cytological sample is adequate in ultrasound low risk (EU-TIRADS ≤3) and in autonomously functioning nodules (LoE = 2); (#5) Thermal ablation may be proposed as first-line treatment for solid, symptomatic, nonfunctioning, benign nodules (LoE = 2); (#6) Thermal ablation may be used for dominant lesions in nonfunctioning multinodular goiter in patients refusing/not eligible for surgery (LoE = 5); (#7) Clinical and ultrasound follow-up is appropriate after thermal ablation (LoE = 2); (#8) Nodule re-treatment can be considered when symptoms relapse or partially resolve (LoE = 2); (#9) In case of nodule regrowth, a new cytological assessment is suggested before second ablation (LoE = 5); (#10) Thermal ablation is an option for autonomously functioning nodules in patients refusing/not eligible for radioiodine or surgery (LoE = 2); (#11) Small autonomously functioning nodules can be treated with thermal ablation when thyroid tissue sparing is a priority and ≥80% nodule volume ablation is expected (LoE = 3).

Due to its wide accessibility, easiness of use, and inexpensive cost, ultrasound (US) examination of the thyroid gland and cervical lymph nodes is commonly employed for the diagnosis of diffuse and nodular thyroid disease and for the pre-operatory staging and follow-up of patients with thyroid malignancy.

The majority of benign thyroid nodules are nearly asymptomatic, remain stable in size, and do not require treatment. However, a minority of patients with growing nodules may complain of local symptoms or have cosmetic concerns, and thus seek surgical consultation.The timely use of ultrasound-guided minimally invasive procedures can change the natural history of benign enlarging thyroid nodules. The procedures produce persistent shrinkage of thyroid nodules and are associated with improvement of local symptoms. Among the various procedures, percutaneous ethanol injection represents the first-line treatment for relapsing thyroid cysts. In solid nonfunctioning nodules, laser and radiofrequency ablation produces a more than 50% reduction in nodular volume that remains persistent over several years. For hyperfunctioning nodules, thermal ablation techniques are not appropriate unless radioactive iodine is contraindicated or not accessible.MITs are best suited for the management of medium or large-sized nodules that are sonographically well visualized. Conversely, large nodules or nodular goiters that extend into the chest are difficult to treat. MITs are performed in outpatient clinics, are less expensive, and have a lower risk of complications, compared to surgery, and usually do not induce thyroid dysfunction. However, malignancy should be ruled out with a dedicated ultrasound neck assessment and repeat fine needle aspiration of the lesion before treatment.

Aim: To evaluate the effectiveness of laser ablation (LA) with or without selective transarterial chemoembolization in patients with large, isolated or oligonodular unresectable neuroendocrine liver matastases. Materials & methods: Ten patients (mean age: 53.6 years ± 14.1; range: 24–79) with neuroendocrine tumors (NETs) and 13 liver matastases (mean diameter: 4.3 ± 2.8 cm; range: 1.5–12) underwent LA alone (n = 9) or LA followed by selective transarterial chemoembolization (n = 3). Results: Complete response was obtained in six patients with LA alone and in two patients with combined treatment. The 5-year overall survival rates from the initial diagnosis and post-treatment were 80 and 50%, respectively. Conclusion: This treatment modality may provide effective control of tumor burden and general symptoms improvement in patients with limited but unresectable disease.

Objective: Selenium (Se) supplementation has been suggested in the treatment of Graves' disease (GD). We sought to investigate Se prescription patterns for GD across European countries. Methods: Members of the European Thyroid Association were invited to participate in an online survey investigating the use of Se in GD either without or with orbitopathy (GO). Of 872 invited members, 244 (28%) completed the survey. After exclusion of basic scientists and non-European members, 197 responses were retrieved out of clinical trials (nearly half of clinician members), of whom 61 do not use Se. Thus, 136 respondents remained for further analyses. Results: Among the 136 analyzed respondents, most (64.7%) were not aware of the Se status in their populations, did not assess Se levels (78.7%), nor considered iodine status (74.3%). In GD without GO, 38.2% recommend Se supplementation ("sometimes" [27.2%], "frequently" [5.9%] or "always" [5.1%]). When GO occurs, 94.1% recommend Se supplementation ("sometimes" [39%], "frequently" [30.1%] or "always" [25%]). Of these, 60.1% recommend Se as an alternative to watchful waiting in patients with mild ocular involvement and 44.9% as an adjuvant to the established treatment modalities in patients with moderate to severe ocular involvement. Conclusions: In Graves' hyperthyroidism without GO, 38.2% of ETA (European Thyroid Association) members recommend Se supplementation. Conversely, Se is recommended by the majority of respondents in GO, both in patients with mild and moderate to severe ocular involvement. This clinical practice is partially in disagreement with current European treatment guidelines that recommend Se as a 6-month treatment in mild GO only.

Surgery is the standard treatment for cervical metastases of medullary thyroid cancer (MTC) diagnosed after initial surgical treatment. Repeated neck dissections, however, carry an elevated risk of complications, have an adverse impact on the quality of life, and sometimes do not achieve cure of the disease Clinical case: In a patient who had undergone two cervical neck dissections complicated by accessory nerve injury, an US-guided laser ablation (LA) of a lymph node metastasis of MTC was performed. LA was performed with two treatments during a five month period. The procedure was carried out with one optical fiber and an energy delivery of 3300 and 360 Joules. Treatments were well tolerated and resulted in complete structural and biochemical cure during a 12 month follow-up. No major complication was registered.LA is a promising tool for the management of relapsing cervical metastases that are localized in non- critical areas and are characterized by low progression rate. Advantages of LA are the outpatient setting, the absence of general anesthesia, the tolerability and the safety of the procedure. Thus, LA may be considered as an alternative approach to surgery or active surveillance for the management of local recurrences of MTC in selected patients.

During the last few decades, a new approach to the nonsurgical management of thyroid nodular disease was proposed and thoroughly assessed. Presently several centres in different parts of the world ...

Thyroid nodules are a common clinical problem, and differentiated thyroid cancer is becoming increasingly prevalent. Six scientific Italian societies entitled to cure thyroid cancer patients (the Italian Thyroid Association, the Medical Endocrinology Association, the Italian Society of Endocrinology, the Italian Association of Nuclear Medicine and Molecular Imaging, the Italian Society of Unified Endocrine Surgery and the Italian Society of Anatomic Pathology and Diagnostic Cytology) felt the need to develop a consensus report based on significant scientific advances occurred in the field. The document includes recommendations regarding initial evaluation of thyroid nodules, clinical and ultrasound criteria for fine-needle aspiration biopsy, initial management of thyroid cancer including staging and risk assessment, surgical management, radioiodine remnant ablation, and levothyroxine therapy, short-term and long-term follow-up strategies, and management of recurrent and metastatic disease. The objective of this consensus is to inform clinicians, patients, researchers, and health policy makers about the best strategies (and their limitations) relating to the diagnosis and treatment of differentiated thyroid cancer.

Well-established criteria for evaluating the response to treatment and the appropriate followup of individual patients are critical in clinical oncology. The current evidence-based data on these issues in terms of the management of gastroenteropancreatic (GEP) neuroendocrine neoplasms (NEN) are unfortunately limited. This document by the Italian Association of Clinical Endocrinologists (AME) on the criteria for the follow-up of GEP-NEN patients is aimed at providing comprehensive recommendations for everyday clinical practice based on both the best available evidence and the combined opinion of an interdisciplinary panel of experts. The initial risk stratification of patients with NENs should be performed according to the grading, staging and functional status of the neoplasm and the presence of an inherited syndrome. The evaluation of response to the initial treatment, and to the subsequent therapies for disease progression or recurrence, should be based on a cost-effective, risk-effective and timely use of the appropriate diagnostic resources. A multidisciplinary evaluation of the response to the treatment is strongly recommended and, at every step in the follow-up, it is mandatory to assess the disease state and the patient performance status, comorbidities, and recent clinical evolution. Local expertise, available technical resources and the patient preferences should always be evaluated while planning the individual clinical management of GEP-NENs.

To evaluate the basal/total ratio of daily insulin dose (b/T) in outpatients with diabetes type 1 (DM1) and type 2 (DM2) on basal-bolus regimen, by investigating whether there is a relationship with HbA1c and episodes of hypoglycemia.Multicentric, observational, cross-sectional study in Italy. Adult DM1 (Total daily insulin dose was significantly higher in DM2 patients (52.3 ± 22.5 vs. 46 ± 20.9 U/day), but this difference disappeared when insulin doses were normalized for body weight. The b/T ratio was lower than 0.50 in both groups: 0.46 ± 0.14 in DM1 and 0.43 ± 0.15 in DM2 patients (The b/T ratio was independent of glycemic control and incidence of hypoglycemia.

Image-guided laser ablation therapy (LAT) of benign thyroid nodules demonstrated favorable results in randomized trials with fixed modalities of treatment. The aim of this retrospective multicenter study was to assess the effectiveness, tolerability, and complications of LAT in a large consecutive series of patients from centers using this technique in their routine clinical activity.Clinical records of 1534 consecutive laser-treated nodules in 1531 patients from eight Italian thyroid referral centers were assessed. Inclusion criteria were as follows: solid or mixed nodules with fluid component up to 40%; benign cytological findings; and normal thyroid function.LAT was performed with a fixed-power protocol, whereas the number of applicators and illumination times were different according to target size. From one to three illuminations with pullback technique and with a total energy delivery based on the nodule volume were performed during the same session. Patients were evaluated during LAT, within 30 days, and 12 months after the procedure.Total number of treatments was 1837; 1280 (83%) of nodules had a single LAT session. Mean nodule volume decreased from 27 ± 24 mL at baseline to 8 ± 8 mL 12 months after treatment (P.001). Mean nodule volume reduction was 72% ± 11% (range 48%-96%). This figure was significantly greater in mixed nodules (79% ± 7%; range 70%-92%) because they were drained immediately before laser illumination. Symptoms improved from 49% to 10% of cases (P.001) and evidence of cosmetic signs from 86% to 8% of cases (P.001). Seventeen complications (0.9%) were registered. Eight patients (0.5%) experienced transitory voice changes that completely resolved at the ear-nose-throat examination within 2-84 days. Nine minor complications (0.5%) were reported. No changes in thyroid function or autoimmunity were observed.Real practice confirmed LAT as a clinically effective, reproducible, and rapid outpatient procedure. Treatments were well tolerated and risk of major complications was very low.

The incidence of thyroid nodules, either solitary or within a multinodular goiter, is steadily increasing during the last decades, and new therapeutic tools, besides the current options of simple surveillance or surgery, would be profitable to attain a personalized management. Most thyroid nodules are asymptomatic and benign at cytological assessment, remain stable over the years, and do not warrant treatment. In other cases, however, the nodules grow progressively, become visible, and eventually cause local symptoms. As in these cases, a protracted clinical observation is frequently followed by surgical consultation; a well-timed use of minimally invasive procedures could reshape the progression of these benign thyroid lesions toward surgery.

Context British Thyroid Association (BTA), American Thyroid Association (ATA), and American Association of Clinical Endocrinologists (AACE/ACE/AME) recommend for thyroid nodules an ultrasound (US)-based stratification of risk of malignancy. Aim of our study was to assess the diagnostic accuracy of US classification systems and their reliability for indication to fine-needle aspiration (FNA). Design Prospective study on 987 thyroid nodules consecutively referred for FNA. US images were independently reviewed by four experts for assignment of malignancy risk. Cytologically benign nodules had confirmation with a second FNA, whereas Bethesda class IV, V, and VI nodules were operated upon. Class III nodules had surgery or follow-up on the basis of clinical, immunocytochemical, and US features. Results BTA: Malignancy rate was 2.8% in benign, 10.0% in indeterminate, 51.3% in suspicion, and 80.9% in malignant US class. Sensitivity was 0.74, specificity was 0.92, and accuracy was 0.89. ATA: Malignancy rate was 0.0% in benign, 2.2% in very low suspicion, 3.0% in low suspicion, 5.8% in intermediate, and 55.0% in high suspicion US class. Sensitivity was 0.81, specificity was 0.87, and accuracy was 0.86. AACE/ACE/AME: Malignancy rate was 1.1% in low-risk, 4.4% in intermediate-risk, and 54.9% in high-risk US class. Sensitivity was 0.82, specificity was 0.87, and accuracy was 0.86. K correlation coefficient was 78.9%, 76.9%, and 82.0% for BTA, ATA, and AACE/ACE/AME classifications. Conclusions Classification systems had elevated predictive value of malignancy in high-risk classes. ATA and AACE/ACE/AME systems were effective for ruling out indication to FNA in low-US-risk nodules. A similar diagnostic accuracy and a substantial interobserver agreement was provided by the three- and the five-category classifications.

Surgery is the long-established therapeutic option for benign thyroid nodules which steadily grow and become symptomatic. However, the cost of thyroid surgery and the risk of temporary or permanent complications with not negligible consequences on the quality of life, remain relevant concerns. Therefore, various minimally invasive therapies (MIT), directed toward office-based management of symptomatic nodules, without requiring general anesthesia, and with negligible damage to the skin and cervical critical structures (i.e., epiaortic vessels and the trachea), have been proposed during the last two decades.
