Abstract
BACKGROUND Radiofrequency ablation (RFA) is a relatively novel procedure in the management of benign nodular goiter. This study was conducted to evaluate the safety and efficacy of ultrasound (US)-guided percutaneous RFA for benign symptomatic thyroid nodules as an alternative to surgery. METHODS The study involved patients for whom a fine needle aspiration biopsy had proved a diagnosis of benign nodular goiter and had nodule-related symptoms such as dysphagia, cosmetic problems, sensation of foreign body in the neck, hyperthyroidism due to autonomous nodules or fear of malignancy. Percutaneous RFA was performed as an outpatient procedure under local anesthesia. The primary outcome was an evaluation of the changes in symptom scores (0-10) for pain, dysphagia and foreign body sensation at the 1st, 3rd, and 6th months after the RFA procedure. Secondary outcomes were assessing volume changes in nodules, complication rates, and changes in thyroid function status. RESULTS A total of 33 patients (24% female, 76% male) and a total of 65 nodules were included into the study. More than one nodule was treated in 63.6% of the patients. We found a statistically significant improvement from baseline to values at the 1st, 3rd, and 6th months, respectively, as follows: pain scores (2.9 ± 2.7, 2.3 ± 2.01, 1.8 ± 1.7, and 1.5 ± 1.2, p 0.005), dysphagia scores (3.9 ± 2.7, 2.6 ± 1.9; 1.7 ± 1.6, and 1.1 ± 0.3, p 0.032), and foreign body sensation scores 3.6 ± 3, 2.5 ± 2.2; 1.6 ± 1.5, and 1.1 ± 0.4, p 0.002).The mean pre-treatment nodule volume was 7.3 ± 8.3 mL. There was a statistically significant size reduction in the nodules at the 1st, 3rd, and 6th months after RFA (3.5 ± 3.8, 2.7 ± 3.4, and 1.2 ± 1.7 mL, p 0.002). The volume reduction was found to be 74% at 6th months following the RFA (p 0.005). 8 patients had autonomously functioning nodules in the pre-treatment period, 50% (n: 4) became euthyroid at the 6th month after RFA. There were no complaints other than pain (12%). CONCLUSION RFA can be an alternative treatment modality in the management of benign symptomatic thyroid nodules. The results showed that it is a safe and effective procedure.

Abstract
The widespread use of ultrasonography places it in a key position for use in the risk stratification of thyroid nodules. The French proposal is a five-tier system, our version of a thyroid imaging reporting and database system (TI-RADS), which includes a standardized vocabulary and report and a quantified risk assessment. It allows the selection of the nodules that should be referred for fine-needle aspiration biopsies. Effort should be directed towards merging the different risk stratification systems utilized around the world and testing this unified system with multi-center studies.

Abstract
BACKGROUND Most benign thyroid nodules found on fine-needle aspiration cytology (FNAC) can be followed with periodic ultrasonography. During follow-up, when nodules grow, re-aspiration or surgical resection for a histologic diagnosis is recommended. However, there is little evidence regarding the malignancy risk associated with nodule growth. METHOD We retrospectively reviewed the records of 542 patients with FNAC-diagnosed adenomatous nodules (ANs) who underwent surgery in 2011-2012 at Kuma Hospital. Among them, 196 patients had surgical resection because of nodule volume growth (median, 1.94 times; range, 1.21-27.60) during the observation period (mean, 45.9 months). Excluding nodule growth, the remaining 346 patients underwent surgery for various reasons including the large size of nodules or the appearance of undefined ultrasound features suspicious for malignancy during follow-up. For comparison, we reviewed 409 patients with FNAC-diagnosed follicular neoplasms (FNs) operated on in 2011-2013. Most (n=327) underwent surgery shortly after the FNAC diagnosis, while 82 patients were observed for a period of time and had a late operation due to nodule volume growth (median, 2.70 times; range, 1.27-15.82). RESULTS The histologic diagnoses of the 196 growing FNAC-diagnosed ANs were 158 ANs, 32 follicular adenomas (FAs), 4 follicular tumors of uncertain malignant potential (FT-UMP; 2%), and 2 malignancies (1%). The 346 patients who underwent surgery for reasons other than nodular growth had 16 FT-UMP (4.6%) and 16 malignancies (4.6%). This suggests that nodule growth itself is not a risk factor for malignancy. On the other hand, there were 23 FT-UMP (28%) and 15 malignancies (18.3%) in the 82 growing FNAC-diagnosed FNs, while 44 FT-UMP (13.5%) and 54 malignancies (16.5%) in the 327 FNAC-diagnosed FN patients who underwent immediate surgery. The malignant potential was significantly higher in the growing-FN group than the immediate-surgery FN group (p<0.05). No significant difference was found in the volume change between the benign and the FT-UMP plus malignant group in the growing FNs, suggesting that a growth rate does not correlate with malignant potential. CONCLUSION This is the first demonstration that the malignancy risk is low in FNAC-diagnosed ANs, even if the nodules grow significantly, whereas FNs have a higher risk when they grow.

Abstract
Ethanol ablation has traditionally been used for treatment of cystic thyroid nodules. Laser ablation and radiofrequency ablation were introduced later and used for treatment of solid thyroid nodules. However, how to select the best treatment modality among the different techniques has, so far, not been determined and causes confusion in clinical practice. Therefore, the necessity for a proper guideline regarding the choice of the preferable treatment modality has been suggested as the use of nonsurgical treatment for benign thyroid nodules has been increasing. This article provides an up-to-date review of nonsurgical treatment of benign thyroid nodules focusing on how to select the best treatment modality according to the composition of thyroid nodules based on the clinical evidence.

Abstract
BACKGROUND While health-related quality of life (HRQoL) issues often prompt treatment of benign nontoxic goiter (NTG), few clinical studies have systematically assessed HRQoL in patients with this condition. The purpose of the present study was to evaluate thyroid-related and generic HRQoL in patients with benign NTG, as compared to the general population, before and six months after treatment. METHODS Thyroid-related and generic HRQoL were assessed with Thyroid Patient-Reported Outcome (ThyPRO) and Medical Outcomes Study 36-item Short Form (SF-36), respectively. Baseline and six-month post-treatment HRQoL assessments were obtained from 111 patients with NTG who underwent radioiodine therapy (32%), hemithyroidectomy (53%), total thyroidectomy (12%), or cyst aspiration with ethanol sclerotherapy (4%). Euthyroid patients were enrolled at baseline, 80% of whom remained euthyroid six months post-treatment, with 20% experiencing subclinical thyroid dysfunction. Normative ThyPRO (n=739) and SF-36 (n=6638) data were collected from representative general population samples. Score differences between patients and the general population were analyzed with multivariate linear regression analysis, adjusting for age, sex, comorbidity, and educational status. Changes in scores between baseline and follow-up were analyzed with the paired t-test, and magnitudes of score changes were evaluated as effect sizes (mean difference/SDbaseline; 0.2-0.5 indicating small, 0.5-0.8 moderate, and >0.8 large effects). RESULTS Patients' baseline scores were significantly worse than those in the general population on 9 of the 13 ThyPRO scales. Six months after treatment, the patients' ThyPRO scores had improved on six scales, with large/moderate effects on the Goiter Symptoms and Anxiety scales. However, on eight scales, the post-treatment patient scores were still significantly worse than the general population scores. At baseline, patients had worse scores than the general population on four of the eight SF-36 scales and the SF-36 Mental Component Summary, none of which improved after treatment. CONCLUSIONS Compared with the general population, patients with NTG had greatest HRQoL impairment at baseline on the Goiter Symptoms and Anxiety scales, which also demonstrated the largest post-treatment improvements. However, both disease-specific and generic HRQoL deficits persisted six months after treatment. In order to improve individualized care, future studies should focus on identifying risk factors for persistent HRQoL deficits and compare HRQoL effects of the various goiter treatment modalities in relation to thyroid phenotype.

Abstract
Multinodular goiter (MNG) is a very common thyroid disorder determined by diverse goitrogenic factors, the most important one being iodine deficiency. The clinical presentation of a patient with MNG varies from a completely asymptomatic goiter to a life-threatening disease due to upper airway compression. Patients can develop underlying subclinical or overt hyperthyroidism due to autonomously hyperfunctioning nodules. In the absence of clinical, ultrasonographic, or cytological findings suggestive of malignancy, the best therapeutic approach for a patient with MNG will depend on the size and location of the goiter, the presence and severity of compressive symptoms, and the presence or absence of thyrotoxicosis. There is still no consensus regarding the treatment of atoxic MNGs. Hence, its optimal management remains controversial; possible therapies include levothyroxine (lT4), surgery, and radioactive iodine ((131)I). Suppressive treatment with lT4 is discouraged due to the development of sub-clinical or overt hyperthyroidism and to its low efficacy when compared with surgery or (131)I. Total thyroidectomy is effective; however, it is associated with the risk of surgical complications and is often refused by the patient. (131)I therapy is an alternative to thyroid surgery to reduce the size of benign MNGs. Based on the ability of recombinant human TSH (rhTSH) to more than double thyroid (131)I uptake, this compound has been evaluated as an adjuvant to (131)I in the treatment of MNG. Very small doses of rhTSH have been used in patients with MNG and few safety concerns have been observed, but the ideal dose, both effective and safe, is yet to be defined.

Abstract
The aim of this study was to investigate the possible influence of different genotypes of the lead single nucleotide polymorphisms (SNPs) rs10917468 and rs12045440 in the CAPZB gene on the thyroid function in papillary thyroid carcinoma (PTC) and benign thyroid neoplasm (BN) patients. In the study, a significant association was detected between rs12045440 and serum TSH concentrations in thyroid tumor patients (p = 0.001). After the adjustment of relevant covariates, the difference between the mean serum TSH levels in different genotypes of rs12045440 was still significant in the BN group (p = 0.003) but was not significant in the PTC cases (p = 0.115). No significant association of rs10917468 with TSH levels was found. The SNP rs12045440 was associated with the serum TSH concentrations in Chinese thyroid tumor patients, especially in benign thyroid tumor cases.

Abstract
PURPOSE To evaluate the efficacy and safety of radiofrequency (RF) ablation for treatment of bilateral thyroid nodules as well as preservation of thyroid function. MATERIALS AND METHODS Between January 2007 and October 2012, 18 patients (16 women and 2 men; mean age, 49.9 y; median age, 44 y; age range, 27-81 y) with bilateral thyroid nodules treated by RF ablation were included in this study. The inclusion criteria included bilateral thyroid nodules, pressure symptoms or cosmetic problems, cytologic confirmation of benignancy without atypical cells, and patient refusal of surgery. We used an RF generator (Cool-tip RF system [Covidien, Boulder, Colorado] or SSP-2000, Taewoong Medical Co, Ltd [Gyeonggi-do, Republic of Korea]) and an 18-gauge internally cooled electrode with 1-cm active tips (Cool-tip [Covidien] or Well-Point RF electrode [Taewoong Medical Co, Ltd]). RF ablation was conducted using the moving shot technique and a trans-isthmic approach. RF ablation was performed in separate sessions for nodules in each lobe. Follow-up ultrasound examinations were performed at 1-6 months, 6-12 months, and during the last month of follow-up. The diameter and volume of the nodule and clinical problems including cosmetic and symptom scores were evaluated before and after the procedure. RESULTS The mean initial nodule size was 4.1 cm ± 1.9, although there was a significant decrease by the time of the last follow-up examination (range, 1-48 mo; mean, 18.1 mo ± 12.8; P < .001, 2.5 cm ± 1.4). The initial nodule volume was 24.4 mL ± 32.2 and was decreased at the last follow-up (6.3 mL ± 19.0, P < .001), with a mean volume reduction of 75.9% ± 19.0. The symptom (P < .001) and cosmetic (P < .001) scores were decreased. Serum hormone levels did not differ significantly before treatment and at the last follow-up (P > .05). CONCLUSIONS RF ablation improves cosmetic problems and symptoms and preserves thyroid function in patients with bilateral thyroid nodules.

Abstract
BACKGROUND The aim of the present trial on ultrasound (US)-guided laser ablation therapy (LAT) of solid thyroid nodules is to assess long-term clinical efficacy, side effects, and predictability of outcomes in different centers operating with the same procedure. PATIENTS Two hundred consecutive patients were randomly assigned to a single LAT session (group 1, 101 cases) or to follow-up (group 2, 99 cases) at four thyroid referral centers. Entry criteria were: solid thyroid nodule with volume of 6-17 mL, repeat benign cytological findings, normal thyroid function, no autoimmunity, and no thyroid gland treatment. METHODS Group 1: LAT was performed in a single session with two optical fibers, a 1064 nm Nd-YAG laser source, and an output power of 3 W. Volume and local symptom changes were evaluated 1, 6, 12, 24, and 36 months after LAT. Side effects and tolerability of treatment were registered. Group 2: Follow-up with no treatment. RESULTS One patient was lost to follow-up in each group. Group 1: Volume decrease after LAT was -49 ± 22%, -59 ± 22%, -60 ± 24%, and -57 ± 25% at 6, 12, 24, and 36 months, respectively (P < .001 vs baseline). LAT resulted in a nodule reduction of >50% in 67.3% of cases (P < .001). Local symptoms decreased from 38 to 8% of cases (P = .002) and cosmetic signs from 72 to 16% of cases (P = .001). Baseline size, presence of goiter (P = .55), or US findings (fluid component ≤ 20% [P = .84], halo [P = .46], vascularization [P = .98], and calcifications [P = .06]) were not predictive factors of a volume decrease > 50%. The procedure was well tolerated in most (92%) cases. No changes in thyroid function or autoimmunity were observed. In group 2, nodule volume increased at 36 months (25 ± 42%; P = .04). The efficacy and tolerability of the procedure were similar in different centers. CONCLUSIONS A single LAT treatment of solid nodules results in significant and persistent volume reduction and local symptom improvement, in the absence of thyroid function changes.

Abstract
A thyroid incidentaloma is an unexpected, asymptomatic thyroid tumor fortuitously discovered during the investigation of an unrelated condition. The prevalence rate is 67% with ultrasonography (US) imaging, 15% with computed tomography (CT) or magnetic resonance imaging (MRI) of the neck, and 1-2% with fluorodeoxyglucose (FDG) positron emission tomography. In the absence of a history of external beam radiation or familial medullary thyroid cancer, the risk of malignancy ranges between 5 and 13% when discovered with US, CT or MRI, but is much higher if based on focal FDG uptake (30%). All patients with a thyroid incidentaloma, independent of the mode of detection, should undergo a dedicated neck US with risk stratification: US imaging allows a quantitative risk stratification of malignancy in thyroid nodules, named 'reporting system' or 'TIRADs' (thyroid imaging reporting and data system). The reported sensitivity ranges from 87 to 95% for the detection of carcinomas and the negative predictive value from 88 to 99.8%. We suggest that the indications for fine-needle aspiration be based mainly on size and US risk stratification. However, the diagnosis and workup of thyroid incidentalomas leads to superfluous surgery for benign conditions, and excess diagnosis and treatment of papillary microcarcinomas, the vast majority of which would cause no harm. Recognizing this must form the basis of any decision as to supplementary investigations and whether to offer therapy, in a close dialogue between patient and physician. The current use of minimally invasive nonsurgical ablation options, as alternatives to surgery, is highlighted.

Abstract
More than one tenth of the world population is to some degree affected by goitre and most of these harbour nodules. The large differences in thyroid disease prevalence between populations may be caused by genetic and environmental factors. Among the latter, iodine deficiency seems by far to be the most important risk factor. Thus, nodular goitre is a condition predominantly seen in iodine deficient areas of the world. In the present review, we evaluated in detail autopsy and ultrasound studies of the thyroid gland. In autopsy studies, large thyroid volumes and high frequencies of goitres have been reported in countries affected by iodine deficiency. Many cross-sectional studies using thyroid ultrasound investigations have been performed world-wide and reported high thyroid volumes and goitre prevalences, and to some extent also high prevalences of thyroid nodules in iodine-deficient countries. Most of these goitres were classified as nodular goitres. On the other hand, few studies have shown that abundant iodine intake may lead to development of diffuse goitres, but world-wide this has been a minor problem compared with development of nodular goitres. In the past century we have observed a trend towards smaller thyroid glands, and hopefully less than 10% of the world population will experience goitre within a few decades.

Abstract
Genetic and a large number of environmental non-iodine-related factors play a role in the cause of nodular goitre. Most evidence for the influence of genetic and environmental factors in the cause of goitre is from cross-sectional, population-based studies. Only a few studies have included prospective data on risk factors for nodular goitre, although few prospective data are available on the effect of iodine and tobacco smoking on goitre development. Goitre is not one single phenotype. Many epidemiological studies do not distinguish diffuse from nodular goitre, as the investigated parameter is often thyroid volume or frequency with increased thyroid volume. Moreover, information on the presence and effect of gene-environment, gene-gene, and environment-environment effect modifications is limited. Thus, firm conclusions about the relative contributions and causality of the investigated risk factors should be made with caution. Smoking seems to be an established risk factor for nodular goitre, possibly with effect modification from iodine intake, as the risk associated with smoking is smaller or absent in areas with sufficient iodine intake. The use of oral contraceptives might have protective effects against goitre, and childbirth is an increased risk factor for goitre in areas with non-optimal iodine intake. Insulin resistance is a recently investigated risk factor, and the risk of goitre may be reversible with metformin treatment. Iodine remains the major environmental risk factor for nodular goitre.

Abstract
Health-related quality of life (HRQoL) assessments are increasingly used to evaluate treatment effects and to shape the delivery of value based care. Valid generic and disease specific tools are available for quantifying HRQoL in patients with non-toxic goitre. However, few studies have applied these validated instruments to assess HRQoL in patients with benign non-toxic goitre. Limited evidence suggests that patients with non-toxic goitre have HRQoL impairments in multiple HRQoL domains. While the HRQoL-impact of non-toxic goitre may be small relative to other severely disabling medical conditions, treatment is almost exclusively elected for HRQoL indications. Thus better quantification of HRQoL, particularly at better (or more favorable) levels where many patients score, is essential. Web and mobile technologies have eased the ability to deliver surveys to patients. Routine consideration of HRQoL provides the opportunity to monitor the impact of treatment on the outcomes most meaningful for patients and the opportunity to help shape the delivery of value based health care.

Abstract
Iodine is essential for the synthesis of thyroid hormones. Iodine deficiency can affect human health in different ways, and is commonly referred to as iodine deficiency disorders (IDD). These range from defective development of the central nervous system during the fetal-neonatal life, to goitre in the adult. Only a few countries were completely iodine sufficient before 1990. Since then, a major effort has been made to introduce salt iodization to ensure sufficient intake of iodine in deficient areas. Iodine prophylaxis has been shown to exert a pivotal role in abating goitre and other iodine-deficiency disorders, and has also been shown to modulate the pattern of thyroid diseases. An increased frequency of thyroid autoimmunity and of hypothyroidism has been observed after introducing iodization programmes. Nevertheless, available evidence clearly confirms that the benefits of correcting iodine deficiency, consisting mainly of reducing nodular goitre and non-autoimmune hyperthyroidism, far outweigh the risks of iodine supplementation.

Abstract
Surgery is the long-established therapeutic option for benign thyroid nodules, which steadily grow and become symptomatic. The cost of thyroid surgery, the risk of temporary or permanent complications, and the effect on quality of life, however, remain relevant concerns. Therefore, various minimally invasive treatments, directed towards office-based management of symptomatic nodules, without requiring general anaesthesia, and with negligible damage to the skin and cervical tissues, have been proposed during the past two decades. Today, ultrasound-guided percutaneous ethanol injection and thermal ablation with laser or radiofrequency have been thoroughly evaluated, and are accessible procedures in specialized centres. In clinical practice, relapsing thyroid cysts are effectively managed with percutaneous ethanol injection treatment, which should be considered therapy of choice. In solid non-functioning thyroid nodules that grow or become symptomatic, trained operators may safely induce, with a single session of laser ablation treatment or radiofrequency ablation, a 50% volume decrease and, in parallel, improve local symptoms. In contrast, hyperfunctioning nodules remain best treated with radioactive iodine, which results in a better control of hyperthyroidism, also in the long-term, and fewer side-effects. Currently, minimally invasive treatment is also investigated for achieving local control of small size neck recurrences of papillary thyroid carcinoma in patients who are poor candidates for repeat cervical lymph node dissection. This particular use should still be considered experimental.

Abstract
Nuclear medicine techniques were first used in clinical practice for diagnosing and treating thyroid diseases in the 1950s, and are still an integral part of thyroid nodules work-up. Thyroid imaging with iodine or iodine-analogue isotopes is the only examination able to prove the presence of autonomously functioning thyroid tissue, which excludes malignancy with a high probability. In addition, a thyroid scan with technetium-99m-methoxyisobutylisonitrile is able to avoid unnecessary surgical procedures for cytologically inconclusive thyroid nodules, as confirmed by meta-analysis and cost-effectiveness studies. Finally, positron emission tomography alone, and positron emission tomography combined with computed tomography scans with (18)F-fluoro-2-deoxy-d-glucose are also promising for diagnosing thyroid diseases, but further studies are needed before introducing them to clinical practice.

Abstract
For treatment of benign nodular goitre the choice usually stands between surgery and (131)I therapy. (131)I therapy, used for 30 years for this condition, leads to a goitre volume reduction of 35-50% within 1-2 years. However, this treatment has limited efficacy if the thyroid (131)I uptake is low or if the goitre is large. Recombinant human TSH (rhTSH)-stimulated (131)I therapy significantly improves goitre reduction, as compared with conventional (131)I therapy without pre-stimulation, and adverse effects are few with rhTSH doses of 0.1 mg or lower. RhTSH-stimulated (131)I therapy reduces the need for additional therapy due to insufficient goitre reduction, but the price is a higher rate of hypothyroidism. Another approach with rhTSH-stimulation is to reduce the administered (131)I activity by a factor that equals the increase in the thyroid (131)I uptake. Using this approach, radiation exposure is considerably reduced while the goitre reduction is similar to that obtained with conventional (131)I therapy.

Abstract
In this systematic review, we investigated the effects of goitre and its treatment on the trachea and the oesophagus. A total of 6355 papers were screened in scientific databases, which disclosed 40 original studies (nine descriptive and 31 interventional). Although most studies are hampered by a number of methodological shortcomings, it is uncontested that goitre affects the trachea as well as the oesophagus in a large proportion of people. This leads to upper airway obstruction, swallowing dysfunction, or both, which may remain undisclosed unless specifically investigated for. Assessment of the tracheal dimensions should be done by magnetic resonance imaging or computed tomography, and detection of upper airway obstruction by flow volume loops, with focus on the inspiratory component. A clinical evaluation of the oesophageal function is difficult to implement and could be replaced by available and validated questionnaires on swallowing. Although radioiodine therapy and thyroidectomy relieve the negative effect of goitre on the trachea and the oesophagus, many issues remain unexplored.

Abstract
Thyroid nodules are common and, depending on the detection technique used, can affect 50% or greater of the population. The primary diagnostic test to assess the nature of these nodules is fine-needle aspiration cytology. Most thyroid nodules are benign and often are multiple. However, the morphology of these nodules may mimic neoplasms showing features such as papillary growth, micro-follicles and even oncocytic metaplasia. Lesions with these features may be considered indeterminate for neoplasm or malignancy, and often require surgical excision to define their nature. The role of cytopathology in this area is to screen those definitely benign nodules, thus preventing surgery and reassuring both the patient and the clinician. In this review, we demonstrate many of the morphological manifestations of nodular goiter and stress the necessity of careful preparatory techniques. Although the past several years have witnessed the development of molecular testing to refine diagnostic cytology in the thyroid, it is still the role of the cytopathologist to identify those "indeterminant" nodules which should be tested. Thus, the cytopathologist contributes both an essential diagnostic and an important cost saving role which hopefully will continue in the future.

Abstract
INTRODUCTION Hyperthyroidism is characterized by increased synthesis and release of thyroid hormones by the thyroid gland. Thyrotoxicosis refers to the clinical syndrome resulting from excessive circulating thyroid hormones, secondary to hyperthyroidism or due to other causes. This article describes evidence-based guidelines for the clinical management of thyrotoxicosis. OBJECTIVE This consensus, developed by Brazilian experts and sponsored by the Department of Thyroid Brazilian Society of Endocrinology and Metabolism, aims to address the management, diagnosis and treatment of patients with thyrotoxicosis, according to the most recent evidence from the literature and appropriate for the clinical reality of Brazil. MATERIALS AND METHODS After structuring clinical questions, search for evidence was made available in the literature, initially in the database MedLine, PubMed and Embase databases and subsequently in SciELO - Lilacs. The strength of evidence was evaluated by Oxford classification system was established from the study design used, considering the best available evidence for each question. RESULTS We have defined 13 questions about the initial clinical approach for the diagnosis and treatment that resulted in 53 recommendations, including the etiology, treatment with antithyroid drugs, radioactive iodine and surgery. We also addressed hyperthyroidism in children, teenagers or pregnant patients, and management of hyperthyroidism in patients with Graves' ophthalmopathy and various other causes of thyrotoxicosis. CONCLUSIONS The clinical diagnosis of hyperthyroidism usually offers no difficulty and should be made with measurements of serum TSH and thyroid hormones. The treatment can be performed with antithyroid drugs, surgery or administration of radioactive iodine according to the etiology of thyrotoxicosis, local availability of methods and preferences of the attending physician and patient.

Abstract
Asymptomatic incidental thyroid nodules (thyroid incidentalomas) are found in up to a third of the adult population. There is notable overlap in the sonographic appearance of benign and malignant thyroid nodules. This paper provides a brief review of the ultrasound findings of thyroid nodules that are suspicious for malignancy with pathologic correlates. We then discuss the standard approach to a fine needle aspiration biopsy of a thyroid nodule at our institution. Finally, we review specific diagnostic challenges in image guided fine needle aspiration biopsies.

Abstract
BACKGROUND Endemic goiter remains a serious public health problem and 75 % of people affected live in underdeveloped countries where treatment is difficult for various reasons. The aim of this article is to report our experience in African countries with the management and surgical treatment of endemic goiter, performed in a nonhospital setting and without general anesthesia in the context of a collaborative development project by experienced endocrine surgeons. METHODS Fifty-six black African patients with a goiter were studied. Those in poor general health, the elderly, patients with either small goiters or clinical hyperthyroidism, and those presenting with an acute episode of malaria were excluded from the study. Cervical epidural anesthesia with spontaneous ventilation was used and a partial thyroidectomy was performed. The technique used, its immediate complications, and early and late follow-up were analyzed. RESULTS Surgery was performed on 31 patients with grades 3 and 4 goiter without mortality and a morbidity rate of 11.9 %, with 97 % of all complications being minor. There were no instances of dysphonia or symptomatic hypocalcemia and the mean stay was 1.57 days (range 1.25-1.93). Follow-up in the first year was 71 % and no case of severe or recurrent hypothyroidism was detected. CONCLUSIONS Surgery without general anesthesia performed in a nonhospital setting in underdeveloped countries in patients with goiter is a viable option with good results and low morbidity.

Abstract
In patients with thyroid nodules, ultrasound (US) imaging represents an indispensable tool for assessment of the risk of malignancy. Over approximately four decades, innovative technology and successive improvements have facilitated its entry into the routine management and greatly improved its predictive value. When US features cannot reliably rule out thyroid cancer, US guidance allows a correct and safe sampling also of small or deeply located thyroid lesions. Obtained in this way, cytological or microhistological specimens may reliably define the nature of most thyroid nodules, and the information from histochemical or molecular markers shows promise in the classification of the remaining indeterminate cases. While a prompt surgical treatment can be offered in the minority of suspicious or definitely malignant cases, most individuals warrant only a follow-up. However, at initial evaluation, or over the years, a fraction of these benign lesions may grow and/or become symptomatic. Such cases may benefit from US-guided minimally invasive procedures as an alternative to surgery. Image-guided percutaneous treatments most often achieve relief of neck complaints, are inexpensive, and can be performed on an outpatient basis. The risk of major complications, after adequate training, is very low. Importantly, thyroid function is preserved. Currently, percutaneous ethanol injection for cystic lesions and thermal ablation, with laser or radiofrequency, for solid nodules are increasingly used and disseminated beyond the initial core facilities. In centres with expertise and high patient volume, their use should be considered as first-line treatment alternatives to surgery for selected patients with benign enlarging or symptomatic thyroid lesions.

Abstract
BACKGROUND Enhanced reduction of multinodular goiter (MNG) can be achieved by stimulation with recombinant human thyrotropin (rhTSH) before radioiodine ((131)I) therapy. The objective was to compare the long-term efficacy and safety of two low doses of modified release rhTSH (MRrhTSH) in combination with (131)I therapy. METHODS In this phase II, single-blinded, placebo-controlled study, 95 patients (57.2 ± 9.6 years old, 85% women, 83% Caucasians) with MNG (median size 96.0 mL; range 31.9-242.2 mL) were randomized to receive placebo (n=32), 0.01 mg MRrhTSH (n=30), or 0.03 mg MRrhTSH (n=33) 24 hours before a calculated (131)I activity. Thyroid volume (TV) and smallest cross-sectional area of trachea (SCAT) were measured (by computed tomography scan) at baseline, six months, and 36 months. Thyroid function and quality of life (QoL) was evaluated at three-month and yearly intervals respectively. RESULTS At six months, TV reduction was enhanced in the 0.03 mg MRrhTSH group (32.9% vs. 23.1% in the placebo group; p=0.03) but not in the 0.01 mg MRrhTSH group. At 36 months, the mean percent TV reduction from baseline was 44 ± 12.7% (SD) in the placebo group, 41 ± 21.0% in the 0.01 mg MRrhTSH group, and 53 ± 18.6% in the 0.03 mg MRrhTSH group, with no statistically significant differences among the groups, p=0.105. In the 0.03 mg MRrhTSH group, the subset of patients with basal (131)I uptake <20% had a 24% greater TV reduction at 36 months than the corresponding subset of patients in the placebo group (p=0.01). At 36 months, the largest relative increase in SCAT was observed in the 0.03 mg MRrhTSH group (13.4 ± 23.2%), but this was not statistically different from the increases observed in the placebo or the 0.01 mg MRrhTSH group (p=0.15). Goiter-related symptoms were reduced and QoL improved, without any enhanced benefit from using MRrhTSH. At three years, the prevalence of permanent hypothyroidism was 13%, 33%, and 45% in the placebo, 0.01 mg, and 0.03 mg MRrhTSH groups respectively. The overall safety profile of the study was favorable. CONCLUSIONS When used as adjuvant to (131)I, enhanced MNG reduction could not be demonstrated with MRrhTSH doses ≤ 0.03 mg, indicating that the lower threshold for efficacy is around this level.

Abstract
OBJECTIVE Based on the assumption that normal TSH concentration rules out the presence of autonomous functioning thyroid nodules (AFTNs), clinical guidelines on the management of thyroid nodules only recommend a thyroid scan if TSH concentration is subnormal. However, the proportion of AFTN presenting with a normal TSH is unknown. Our objective is therefore to determine the proportion of AFTNs with a normal TSH level to ascertain whether a normal TSH really rules out an AFTN. DESIGN Retrospective study on 368 patients with an AFTN. METHODS Thyroid scans with a diagnosis of AFTN were reviewed retrospectively by one of us (R Moreno-Reyes), blinded to the clinical data. The diagnosis of solitary AFTN was confirmed in 368 patients. Among them, we selected 217 patients based on the absence of another thyroid nodule >10 mm, the absence of medical conditions able to interfere with thyroid function, and the completeness of the data. RESULTS The proportion of AFTNs with normal TSH was 49%. This proportion increased to 71% in patients for whom thyroid scan was performed in the workup of a thyroid nodule. CONCLUSIONS Our data suggest that serum TSH is not an effective screening tool to diagnose AFTNs. Using 'TSH-only' screening, as recommended by the majority of guidelines, the diagnosis of AFTN would have been missed in 71% of our patients in the workup of a thyroid nodule. Thyroid scan remains the gold standard for detecting AFTN and should be considered before performing fine-needle aspiration cytology (FNAC), as the reliability of FNAC in an unsuspected AFTN remains unclear.

Abstract
In multinodular goitre (MNG), low radioiodine (RAI) activity after recombinant human (rh) TSH is able to reduce thyroid volume (TV) and improve symptoms. Our aim was to evaluate the long-term outcome of RAI after rhTSH treatment in patients who were divided according to their baseline TSH levels. Eighteen patients (69.2 ± 6.1 year) presented non-toxic (TSH >0.3 mIU/l) MNG (TV: 61.0 ± 3.8 ml; group 1), while 13 patients (74.1 ± 7.9 year) had non-autoimmune pre-toxic (TSH <0.3 mIU/l) MNG (TV: 82.6 ± 14.4 ml; group 2). TSH, thyroid hormones, TV (by ultrasonography), body mass index (BMI), symptoms and quality of life (QoL) were evaluated. Treatment induced short-term thyrotoxicosis in both groups, but this was slightly more marked in group 2 than in group 1. The number and severity of adverse events were similar. The follow-up period was 55.3 ± 4.1 months in group 1 and 57.2 ± 5.1 months in group 2. The final TV reduction was similar in groups 1 (63.4 ± 3.6%) and 2 (57.2 ± 4.6%) and TV reduction positively correlated only with initial TV. At the last examination, 14 group-1 subjects were on L-T4 therapy, while 2 group-2 subjects were on methimazole. An increase in BMI was noted only in group 2. MNG-related symptoms were significantly reduced in both groups. Symptoms related to sub-clinical hyperthyroidism improved in group 2, while no significant changes in QoL were noted in either group. This study confirms the effectiveness of rhTSH adjuvant treatment in reducing TV after low RAI activities, irrespective of baseline thyroid status. TSH levels <0.3 mIU/l proved to be predictive of a more severe thyrotoxic phase after rhTSH and RAI, while initial TSH levels >0.3 mIU/l were more frequently followed by a need for L-T4 therapy. Compressive symptoms improved in the majority of subjects.

Abstract
OBJECTIVES The clinical challenge of managing thyroid nodules nowadays is to diagnose the minority of malignant disease. Real-time ultrasound elastography, which can measure tissue elasticity, is used as a complement to conventional sonography for improving the diagnosis of thyroid tumors. There are 2 common criteria for evaluating an elastogram: the elasticity score and strain ratio. This meta-analysis was performed to expand on a previous meta-analysis to assess the diagnostic power of ultrasound elastography in differentiating benign and malignant thyroid nodules for elasticity score and strain ratio assessment. METHODS The MEDLINE, EMBASE, PubMed, and Cochrane Library databases up to January 31, 2013, were searched. The pooled sensitivity, specificity, and summary receiver operating characteristic curve were obtained from individual studies with a random-effects model. The extent and sources of heterogeneity were explored. RESULTS A total of 5481 nodules in 4468 patients for elasticity score studies and 1063 nodules in 983 patients for strain ratio studies were analyzed. The overall mean sensitivity and specificity of ultrasound elastography for differentiation of thyroid nodules were 0.79 (95% confidence interval [CI], 0.77-0.81) and 0.77 (95% CI, 0.76-0.79) for elasticity score assessment and 0.85 (95% CI, 0.81-0.89) and 0.80 (95% CI, 0.77-0.83) for strain ratio assessment, respectively. The areas under the curve for the elasticity score and strain ratio were 0.8941 and 0.9285. CONCLUSIONS These results confirmed those obtained in the previous meta-analysis. Ultrasound elastography has high sensitivity and specificity for identification of thyroid nodules. It is a promising tool for reducing unnecessary fine-needle-aspiration biopsy.

Abstract
BACKGROUND Goiter, or benign enlargement of the thyroid gland, can be asymptomatic or can cause compression of surrounding structures such as the esophagus and/or trachea. The options for medical treatment of euthyroid goiter are short-lived and are limited to thyroxine hormone suppression and radioactive iodine ablation. The objective of this statement article is to discuss optimal surgical management of goiter. METHODS A task force was convened by the Surgical Affairs Committee of the American Thyroid Association and was tasked with writing of this article. RESULTS/CONCLUSIONS Surgical management is recommended for goiters with compressive symptoms. Symptoms of dyspnea, orthopnea, and dysphagia are more commonly associated with thyromegaly, in particular, substernal goiters. Several studies have demonstrated improved breathing and swallowing outcomes after thyroidectomy. With careful preoperative testing and thoughtful consideration of the type of anesthesia, including the type of intubation, preparation for surgery can be optimized. In addition, planning the extent of surgery and postoperative care are necessary to achieve optimal results. Close collaboration of an experienced surgical and anesthesia team is essential for induction and reversal of anesthesia. In addition, this team must be cognizant of complications from massive goiter surgery such as bleeding, airway distress, recurrent laryngeal nerve injury, and transient hypoparathyroidism. With careful preparation and teamwork, successful thyroid surgery can be achieved.

Abstract
BACKGROUND Non-thyroidal illness (NTI) refers to changes in thyroid hormone levels in critically ill patients in the absence of primary hypothalamic-pituitary-thyroid dysfunction, and these abnormalities usually resolve after clinical recovery. However, NTI can be accompanied by primary thyroid dysfunction. We report herein a case of a woman with NTI accompanied by primary hyperthyroidism. CASE PRESENTATION A 52-year-old female was admitted to the intensive care unit with heart failure and atrial fibrillation. She had a longstanding thyroid nodule, and a thyroid function test revealed low levels of triiodothyronine and free thyroxine as well as undetectable thyroid stimulating hormone (TSH). She was diagnosed with NTI, and her TSH level began to recover but not completely at discharge. The thyroid function test was repeated after 42 months to reveal primary hyperthyroidism, and a thyroid scan confirmed a toxic nodule. CONCLUSION This case suggests that although NTI was diagnosed, primary hyperthyroidism should be considered as another possible diagnosis if TSH is undetectable. Thyroid function tests should be repeated after clinical recovery from acute illness.

Abstract
CONTEXT Recurrence rate, after aspiration, in cystic thyroid nodules is very high. Interstitial laser photocoagulation (ILP) is a minimally invasive procedure that reduces the need for surgery in patients with a benign solid thyroid nodule. OBJECTIVE The aim of the study was to evaluate the efficacy of ILP on remission rates in recurrent, predominantly cystic thyroid nodules. DESIGN AND METHODS Forty-four consecutive outpatients with a symptomatic, recurrent, and cytologically benign cystic (cyst volume ≥ 2 mL) thyroid nodule were randomized to a single aspiration with (n = 22) or without (n = 22) subsequent ILP and followed up after 1, 3, and 6 months. RESULTS Successful outcome (cyst volume ≤ 1 mL) was obtained in 15 of 22 (68%) patients in the ILP group, compared to 4 of 22 (18%) in the aspiration group (P = .002). In the ILP group, the solid part of the nodule was reduced from a median of 1.8 to 1.0 mL (P = .02). In the aspiration-alone group, neither the cyst volume nor the solid nodule volume was significantly reduced. The reduction in median visual analog score (0-10 cm) for pressure symptoms was significantly higher in the ILP group (from 3.0 to 0.0 cm) than in the aspiration-alone group (from 4.0 to 3.5 cm) (P = .006, between groups). No major side effects occurred, and thyroid function was unaffected throughout. CONCLUSIONS US-guided aspiration and subsequent ILP of benign recurrent predominantly cystic thyroid nodules is safe. It significantly reduces recurrence rate, the volume of the solid nodule component, and pressure symptoms. ILP constitutes an important alternative to surgery in such patients.

Abstract
BACKGROUND High serum thyroid-stimulating hormone (TSH) is associated with thyroid carcinoma in patients with thyroid nodules. However, previous studies suggests that TSH is not involved in the pathogenesis of small thyroid carcinomas. We performed this study to evaluate serum TSH as a malignancy predictor in the assessment of small thyroid nodules. METHODS We retrospectively analyzed 3791 patients who underwent thyroidectomy. We classified all patients into 3 to 5 groups by serum TSH or nodule size and analyzed the association of serum TSH and risk of papillary thyroid carcinoma (PTC). RESULTS The frequency of PTC increased as serum TSH increased. Serum TSH and older age were associated with the risk of PTC in multivariate analysis (p < .0001). In subgroup analysis, the risk of PTC increased as serum TSH increased with thyroid nodules > 1 cm (p < .05). CONCLUSIONS Serum TSH may not be useful for clinical risk assessment of small thyroid nodules.

Abstract
OBJECTIVE Ultrasound elastography (USE) assesses lesion stiffness by evaluating tissue distortion in response to stress; it is emerging as a potentially useful tool to augment the ultrasound characterisation of thyroid nodules. The aim of this study was to assess the accuracy of USE examination of thyroid nodules compared with pathological outcome, especially to determine whether USE could reliably detect benign nodules and reduce the numbers of ultrasound guided fine needle aspiration cytology (USgFNAC). DESIGN Over a three-year period, thyroid nodules were initially characterised by B-mode ultrasound (US) findings. Where USgFNAC was indicated by clinical concern and/or the sonographic appearances, the lesion was then subjected to USE by an experienced operator prior to the USgFNAC. PATIENTS 147 thyroid nodules were examined by USE and USgFNAC in 146 patients. MEASUREMENTS The elastographic appearance was subjectively categorized at the time of the examination (soft, intermediate or hard) and subsequently compared with the cytological/histological outcome. RESULTS A total of 122 nodules were non-neoplastic, 5 nodules were benign neoplasms, 10 nodules had indeterminate cytology and 10 were malignant neoplasms. The sensitivity of USE for malignancy was 90.0%, specificity was 79.6%, PPV was 24.3%, NPV was 99.1% and accuracy was 80.3%. CONCLUSION Thyroid nodules that are soft at USE have a high likelihood of being non-neoplastic and subjective USE assessment of thyroid nodules by an experienced operator can be a useful means of avoiding USgFNAC for benign nodules. In contrast, we suggest that all nodules that are intermediate or hard on USE undergo USgFNAC.

Abstract
BACKGROUND The familial clustering of multinodular goitres (MNGs) with a dominant mode of inheritance has been repeatedly reported. Linkage studies have revealed several genetic loci responsible for familial MNG; however, most of the causative variants remain unknown. METHODS AND RESULTS Through linkage analysis using single-nucleotide polymorphism markers, we identified a new MNG locus on 19p13.2-q12 in a five-generation Japanese MNG family. Subsequent mutation searches focusing on the candidate 25-Mb region of chromosome 19 identified a heterozygous mutation, c.879_880delinsA, p.Asp294Thr, fs*23, in exon 3 of the KEAP1, which plays a central role in the cytoprotection pathway against oxidative stress. Reverse transcriptase-PCR analysis showed low expression of wild type KEAP1 accompanied by no transcription product of mutant allele in the normal and goitre region of thyroid tissues obtained from the proband. In agreement with previous studies showing that KEAP1 negatively regulates NFE2L2, the NFE2L2 target genes GSTA4 and GCLC were up-regulated in the thyroid tissues of the patient. CONCLUSIONS This study identified the first KEAP1 mutation in MNG. The results provide insights into the pathogenesis of goitre which develops in the organ continuously exposed to oxidative stress during hormone synthesis.

Abstract
Background There is no consensus on the optimal treatment of multinodular goiter (MNG), but in the past few years, the use of radioiodine has increased. This study’s objective was to evaluate adjuvant methimazole (MMI) therapy to increase and standardize radioiodine uptake (RAIU) with a fixed therapeutic 131I dose of 1110 MBq (30 mCi). Methods Our study included 5 women with MNG treated with MMI, 10 - 15 mg/day for 2 to 4 months, prior to the administration of 1110 MBq 131I (30 mCi); none of the patients developed hypothyroidism during MMI therapy and had average basal TSH levels of 0.32 ± 0.39 mIU/L that increased to 2.6 ± 0.9 mIU/L (P = 0.07). Results RAIU increased from 25.6 ± 8.7% to 49.2 ± 8.3% (P = 0.003). All patients were followed for 12 months: median thyroid volume (TV) decreased from 77.2 mL (32.9 - 124.2) to 48.8 ml (12.4 - 68.9) with an average decrease of 46.4 ± 14.8% (P = 0.01). All patients developed hypothyroidism during the first 6 months after radioiodine therapy. Conclusions This new therapeutic protocol using MMI as adjuvant therapy is effective in increasing RAIU as well as the deleterious effects of 131I, without increasing the required dose, but leading to thyroid volume decreases similar to those reported with the use of recombinant human thyrotropin (rhTSH) or higher radioiodine doses.

BACKGROUND To confirm whether clinical and biochemical parameters or Hashimoto's thyroiditis (HT) could predict the risks of malignancy among subjects who underwent thyroidectomy, as well as to determine the influence of HT on the biological behavior of papillary thyroid cancer (PTC). METHODS A total of 2,052 patients who underwent initial thyroidectomy were enrolled between June 2006 and August 2008. Serum free T4, free T3, thyrotropin (TSH), thyroglobulin, thyroglobulin antibody, antimicrosomal antibody, tumor-associated status, and thyroid disorders were documented. RESULTS Binary logistic regression analysis was performed to define the risk predictors for thyroid cancer. Finally, calcification, HT, TSH, and age, were entered into the multivariate model. Multivariate logistic regression analysis revealed the risk of thyroid cancer increases in parallel with TSH concentration within normal range, and the risk for malignancy significantly increased with serum TSH 1.97-4.94 mIU/L, compared with TSH less than 0.35 mIU/L (OR = 1.951, 95% CI = 1.201-3.171, P = 0.007). Increased risks of thyroid cancer were also detected among the patients with HT (OR = 3.732, 95% CI = 2.563-5.435), and microcalcification (OR = 14.486, 95% CI = 11.374-18.449). The effects of HT on the aggressiveness of PTC were not observed in extrathyroidal invasion (P = 0.347), capsular infiltration (P = 0.345), angioinvasion (P = 0.512), and lymph node metastases (P = 0.634). CONCLUSIONS The risk of malignancy increases in patients with higher level TSH within normal range, as well as the presence of HT and microcalcification. No evidence suggests that coexistent HT alleviates the aggressiveness of PTC.

Abstract
INTRODUCTION Over the past years, the incidence of thyroid cancer has surged not only in Germany but also in other countries of the Western hemisphere. This surge was first and foremost due to an increase of prognostically favorable ("low risk") papillary thyroid microcarcinomas, for which limited surgical procedures are often sufficient without loss of oncological benefit. These developments called for an update of the previous practice guideline to detail the surgical treatment options that are available for the various disease entities and tumor stages. METHODS The present German Association of Endocrine Surgeons practice guideline was developed on the basis of clinical evidence considering current national and international treatment recommendations through a formal expert consensus process in collaboration with the German Societies of General and Visceral Surgery, Endocrinology, Nuclear Medicine, Pathology, Radiooncology, Oncological Hematology, and a German thyroid cancer patient support organization. RESULTS The practice guideline for the surgical management of malignant thyroid tumors includes recommendations regarding preoperative workup; classification of locoregional nodes and terminology of surgical procedures; frequency, clinical, and histopathological features of occult and clinically apparent papillary, follicular, poorly differentiated, undifferentiated, and sporadic and hereditary medullary thyroid cancers, thyroid lymphoma and thyroid metastases from primaries outside the thyroid gland; extent of thyroidectomy; extent of lymph node dissection; aerodigestive tract resection; postoperative follow-up and surgery for recurrence and distant metastases. CONCLUSION These evidence-based recommendations for surgical therapy reflect various "treatment corridors" that are best discussed within multidisciplinary teams and the patient considering tumor type, stage, progression, and inherent surgical risk.

Abstract
BACKGROUND Ultrasonography (US) plays a crucial role in the diagnostic management of thyroid nodules, but its widespread use in clinical practice might generate heterogeneity in ultrasound reports. OBJECTIVES The aims of the study were to propose (a) a standardized lexicon for description of thyroid nodules in order to reduce US reports of interobserver variability and (b) a US classification system of suspicion for thyroid nodules in order to promote a uniform management of thyroid nodules. METHODS RELEVANT PUBLISHED ARTICLES WERE IDENTIFIED BY SEARCHING MEDLINE AT PUBMED COMBINING THE FOLLOWING SEARCH TERMS: ultrasonography, thyroid, nodule, malignancy, carcinoma, and classification system. Results were supplemented with our data and experience. RESULTS A STANDARDIZED US REPORT SHOULD ALWAYS DOCUMENT POSITION, EXTRACAPSULAR RELATIONSHIPS, NUMBER, AND THE FOLLOWING CHARACTERISTICS OF EACH THYROID LESION: shape, internal content, echogenicity, echotexture, presence of calcifications, margins, vascularity, and size. Combining the previous US features, each thyroid nodule can be tentatively classified as: malignant, suspicious for malignancy, borderline, probably benign, and benign. CONCLUSIONS We propose a standardized US report and a tentative US classification system that may become helpful for endocrinologists dealing with thyroid nodules in their clinical practice. The proposed classification does not allow to bypass the required cytological confirmation, but may become useful in identifying the lesions with a lower risk of neoplasm.

Abstract
OBJECTIVE Although fine needle aspiration biopsy has a high sensitivity in thyroid nodule assessment, ultrasonography findings should not be underestimated. With this study, we aimed to evaluate cytologically benign nodules smaller than two centimeters, where ultrasonography findings were suspicious. MATERIAL AND METHODS Thirty-one patients undergoing thyroidectomy between January 2009 and January 2013 were included in this retrospectively designed study. Thyroid ultrasonography and thyroid fine needle aspiration biopsy (FNAB) results were evaluated. Ultrasonographically, all patients had multinodular tissue formation and nodules had at least one of the suspicious features (nodules with hypoechogenicity, irregular margins, absence of halo, taller-than-wide, increased vascularity and microcalcifications). Maximum size of the nodules was 2 cm. Thyroidectomy was performed in this ultrasonographically suspicious, but cytologically benign group due to clinical suspicion, cosmetic reasons or patient preference. RESULTS All patients underwent a total thyroidectomy. The group consisted of 27 female and 4 male patients, with a mean age of 49.5 years. According to the final pathology reports, there were 13 (41.9%) multinodular goiters, 2 (6.4%) follicular adenomas, 1 (3.2%) Hashimoto's thyroiditis and 15 (48.3%) thyroid cancers. Patients with cancer had at least two suspicious ultrasound findings. Except five patients with papillary microcarcinoma, cancer was diagnosed in ultrasonographically suspicious nodules in all patients. The percentage of patients with benign FNAB results, but with at least two suspicious ultrasound findings of malignancy in the biopsied nodules, was 32.2%. CONCLUSION FNAB remains to be the gold standard in the management of ultrasonographically suspicious nodules smaller than 2 centimeters. Nevertheless, due to its high sensitivity, in case of presence of suspicious features on ultrasonography, we believe that thyroidectomy should be a treatment option if there is a clinical suspicion and the patient carries at least two suspicious ultrasonography findings.

Abstract
PURPOSE Percutaneous radiofrequency thermal ablation (RTA) was reported as an effective tool for the management of thyroid nodules (TNs). The aim of this study was to investigate the effects of RTA and to establish whether they were treatment-related by comparison with a matched, untreated control group. PATIENTS AND METHODS The study population included 40 patients with compressive TNs: 22 had nontoxic TNs, and 18 had toxic TNs and were treated with methimazole. In all patients, a fine-needle aspiration cytology was performed to exclude a thyroid malignancy. STUDY DESIGN Twenty patients were treated with RTA (group A), and 20 others did not receive any treatment (group B). At baseline, age, gender, and TN features did not differ significantly between groups. All patients were clinically, biochemically, and morphologically evaluated at baseline and after 1, 3, 6, and 12 months. RESULTS TN volume significantly decreased in group A (1.8 ± 0.3 ml at 12 months vs. 13.3 ± 1.8 ml at baseline; P < 0.0001) and remained stable in group B [11.7 ± 1.5 ml at 12 months vs. 11.2 ± 1.5 ml at baseline; P = not significant (NS)]. At 3-, 6-, and 12-month evaluations, TN volume was significantly lower in group A than in group B (P < 0.005). At the end of the follow-up, pressure symptoms were improved in all patients in group A but persisted unchanged in group B. In group A, hyperthyroidism completely recovered in 40% and improved in 40% of patients with toxic TNs, whereas it persisted in all patients with toxic TNs in group B. RTA was safe and well tolerated in all patients. CONCLUSIONS RTA induced a marked TN volume shrinkage resulting in parallel improvement of pressure symptoms. In most patients with toxic TNs, hyperthyroidism significantly improved as well. RTA may represent a valid therapeutic approach in patients with TNs not receiving conventional treatments.
