Abstract
Iodine deficiency disorders is a sweeping term that includes structural and functional impairment of the thyroid gland.These clinical guidelines include algorithms for the diagnosis and treatment of euthyroid goiter and nodular/ multinodular goiter in adults and children. In addition, these clinical guidelines contain information on methods for an adequate epidemiological assessment of iodine deficiency disorders using such markers as the percentage of goiter in schoolchildren, the median urinary iodine concentration, the level of neonatal TSH, the median thyroglobulin in children and adults. As well from these clinical guidelines, you can get to know the main methods and groups of epidemiological studies of iodine deficiency disorders.

Abstract
Image-guided ablation of thyroid disease is increasingly being commonly reported. Techniques including ethanol injection and thermal ablation using radio-frequency, laser, and microwave devices have been described. Minimally invasive approaches to the management of benign cystic, solid, and functional thyroid nodules as well as both primary and recurrent thyroid malignancy have been reported. The purpose of this article is to review the current evidence relating to image-guided ablation of thyroid disease with a focus on clinical outcomes and complication rates for patients treated with this minimally invasive approach.

Abstract
CONTEXT Ultrasound (US)-guided percutaneous ethanol injection (PEI) has been proposed for treatment of benign thyroid nodules (TNs). However, there is no consensus for the optimal amount of ethanol injection, number of applications, and time to re-evaluation in order to achieve maximum volume reduction with minimum adverse effects. OBJECTIVE The purpose of the present study was to analyze the effectiveness of an US-guided PEI protocol to treat solid and mixed TNs based on a new target outcome. PATIENTS AND METHODS We performed a prospective study evaluating the results of PEI in 52 patients with benign solid and mixed TNs. The ethanol dose was fixed in 30% of the nodular volume per session. Patients returned 1 month after each session for US re-evaluation. Therapeutic success was defined as volume reduction of at least 30% associated with disappearance of clinical symptoms and a complete esthetic satisfaction reported by the patient. RESULTS We performed a mean of 2.8 ± 1.9 PEI sessions, with an average total volume of ethanol injected of 9.1 ± 10.3 ml, and a follow-up time of 10.0 ± 8.7 months. There was a reduction of at least 50% of the initial nodular volume in 33 patients (63.5%). In 11 patients (21.2%), the reduction did not reach 50% (mean reduction of 31 ± 11%), but 6 of them reported esthetically satisfactory results and treatment was stopped. Our therapeutic success rate considering the patients with esthetic improvement was 75%. There were no severe complications. CONCLUSION Our protocol is effective and safe to treat solid and mixed benign TNs based on our established outcome.

Abstract
PURPOSE To compare the efficacy of percutaneous sodium tetradecyl sulfate (STS) injection with ethanol injection in the treatment of benign nonfunctioning thyroid nodules. MATERIALS AND METHODS This prospective study included 47 patients with 50 benign thyroid nodules. The lesions were randomly assigned into two groups: 20 in the ethanol arm and 30 in the STS arm. The mean lesion volume was 25.6 mL ± 28.5 (range, 4-122.1 mL) in the ethanol arm and 25.4 mL ± 27 (range, 0.72-129 mL) in the STS arm. One sitting of sclerosant injection was done in 20 lesions, and two injections, three injections, four injections, five injections, six injections, seven injections, and eight sittings of injections were done in 9 lesions, 4 lesions, 8 lesions, 4 lesions, 2 lesions, 2 lesions, and 1 lesion. The mean volumes of the instilled ethanol and STS were 5.3 mL and 7.8 mL, respectively, per sitting. Follow-up sonography was performed at 1, 3, 6, and 12 months after the procedure. RESULTS The final 12-month follow-up lesion volumes were 4.1 mL ± 3.7 (range, 0.3-15.2 mL) in the ethanol group and 4.4 mL ± 5.8 (range, 0.01-29.6 mL) in the STS group (P = .85). The mean volume reduction was 84% and 82.8% in the two groups. No significant adverse effects were seen in either of the two groups. CONCLUSIONS Sonographically guided percutaneous ethanol and STS injections are not significantly different from each other in terms of the volume reduction achieved in benign nonfunctioning thyroid nodules.

Abstract
Thyroid cysts and pseudocysts, or hemorrhagic cysts, are quite frequent thyroid pathologies. Surgical theraphy has always been the treatment of choice in this pathology, but percutaneous ethanol injection (PEI) is becoming still more common. PEI was originally used in the treatment of liver nodules and subsequently in solid, hyperfunctioning thyroid nodules, but today it is used exclusively in cysts. The aim of this study was to evaluate the efficacy of PEI in reducing thyroid cyst volume 12 and 84 months after treatment and to compare cost-benefit to that of surgical treatment. The study includes 110 consecutive patients, who all underwent PEI after cytological analysis had excluded the presence of neoplasia. All patients had refused surgical treatment. One patient died during the follow-up due to cerebral hemorrhage. Each patient received an average of 5.3 ± 2.7 PEI treatments. After 12 months, volume was reduced by 82.6% and after 84 months by 93.03%. Dysphonia occurred in 2 cases of which one resolved spontaneously and one received cortisone therapy. The cost of PEI treatment is considerably lower than the cost of surgical therapy (the cost saving in our patient population was about €200,000). PEI should therefore be preferred to surgical treatment due to its efficacy and lower cost.

Abstract
This study was designed to clarify the long-term efficacy and safety of percutaneous ethanol injection (PEI) therapy in benign nodular and cystic thyroid diseases, and to evaluate response by criteria defined as disappearance of hot nodule. Solid nodule and complex cyst were classified into three groups in accordance with volume reduction. In autonomously functioning thyroid nodule (AFTN), disappearance of hot nodule with normalization of thyroid hormone level and restored extra-nodular uptake was defined to be curative. In solid nodule (n = 198) and complex cyst (n = 432), initial volume was significantly reduced to post-PEI and final volumes, and volume reduction persisted during follow-up period. Complete response, partial response and no response were as follows: 17.2%, 71.7%, 11.1% in solid nodule; 19.0%, 60.4%, 20.6% in complex cyst, respectively. Differences of volume reduction according to initial volume (> or =10 mL vs. <10 mL) were significant. Correlations between initial and final volumes, and between initial volume and volume reduction were also significant. In 24 patients with AFTN, when effectiveness was assessed by disappearance of hot nodule, only 1 case was curative. Reexpansion or recurrence was observed in 5 cases. Complications developed in 9.0% but there was no permanent or serious complication in this study. In conclusion, our data suggest that PEI therapy could be an effective and safe therapeutic modality for benign nodular and cystic thyroid diseases especially when initial volume is more than 10 mL, but may not induce disappearance of hot nodule itself in AFTN.

Abstract
PURPOSE To evaluate in vivo the safety and effectiveness of percutaneous laser thermal ablation (LTA) in the debulking of thyroid lesions. MATERIALS AND METHODS Twenty-five adult patients at poor surgical risk with cold nodules (n = 8), autonomously hyperfunctioning thyroid nodules (n = 16), or anaplastic carcinoma (n = 1) underwent LTA. One to four 21-gauge spinal needles were inserted with ultrasonographic (US) guidance into the thyroid lesions. A 300-microm-diameter quartz optical fiber was advanced through the sheath of the needle. Nd:YAG laser was used with output power of 3-5 W. Side effects, complications, and clinical and hormonal changes were evaluated at the end of LTA and during follow-up. Linear regression analysis was used to investigate the correlation between energy delivered and reduction in nodule volume. Volume of induced necrosis and reduction in nodule volume were assessed with US or computed tomography. RESULTS LTA was performed without difficulties in 76 LTA sessions. After treatment with 5 W, two patients experienced mild dysphonia, which resolved after 48 hours and 2 months. Improvement of local compression symptoms was experienced by 12 of 14 (86%) patients. Thyroid-stimulating hormone (TSH) was detectable in five of 16 (31%) patients with hyperfunctioning nodules at 6 months after LTA. Volume of induced necrosis ranged from 0.8 to 3.9 mL per session. Anaplastic carcinoma treated with four fibers yielded 32.0 mL of necrosis. Echo structure and baseline volume did not influence response. Energy load and reduction in nodule volume were significantly correlated (r(2) =.75, P <.001). Mean nodule volume reduction at 6 months in hyperfunctioning nodules was 3.3 mL +/- 2.8 (62% +/- 21.4 [SD]) and in cold nodules was 7.7 mL +/- 7.5 (63% +/- 13.8). CONCLUSION LTA may be a therapeutic tool for highly selected problems in the treatment of thyroid lesions.

Abstract
GOAL To establish the role of percutaneous ethanol injection (PEI) treatment in benign thyroid lesions by evaluating: (1) the long-term efficacy and side effects of the treatment, (2) the factors predictive of efficacy of PEI, and (3) the cost effectiveness of the procedure. MATERIALS AND METHODS Fifty-eight recurrent cystic nodules, 95 autonomously functioning nodules (AFTN), and 17 hyperfunctioning nodules causing thyrotoxicosis (toxic nodules) were treated by PEI from 1990 to 1996 in our center. Ultrasound (US) and color flow doppler (CFD) examinations were carried out before and after each treatment. In patients with AFTN, serum thyrotropin (TSH), free triiodothyronine (FT3), free thyroxine (FT4), thyroid peroxidase antibody (TPOAb) levels were tested before and after PEI. All patients were independently reexamined by two external reviewers after a minimum follow-up of 5 years (median, 6.9 years). RESULTS The median number of treatments was 2.0 (range, 1.0-4.0) for cystic nodules, 4 (range, 2.0-6.0) for AFTN, and 5 (range, 3.0-7.0) for toxic nodules. At the 5-year evaluation cystic nodules showed a volume reduction greater than 75% versus baseline in 86.2% of cases and an improvement of local symptoms in 91.4% of cases. AFTN presented serum TSH within normal limits in 60.0% of patients. Toxic nodules showed a detectable serum TSH and normal FT3 and FT4 values in 35.3% of cases. Two cases of transient dysphonia were observed. In cystic lesions no significant correlation was found between the baseline and the final volume (r2 = 0.17) and no significant predictor of treatment efficacy was found. However, unilocularity was associated with a lower number of treatments than multilocularity (median, 2.0 vs. 3.0). Independent predictors of clinical efficacy in both AFTN and toxic nodules were a baseline volume less than 5.0 mL and a fluid component greater than 30% (odds ratio [OR] = 6.1 and 3.3, respectively). CONCLUSIONS Most recurrent cystic lesions of the thyroid can be cured by PEI, which should become the first line of treatment. The majority of AFTN and toxic nodules with volume less than 5.0 mL presented a marked volume decrease and normal serum TSH levels when treated by PEI, which seems a valid alternative to clinical follow-up alone in patients refusing 131I. PEI is not indicated in large or toxic nodules, for which 131I is the treatment of choice.

Abstract
PURPOSE To provide an overview of the state of the art of tissue chemoablation in animal and human organs and cancers. We also describe our experience with the feasibility, predictability, and reproducibility of necrosis produced by needle chemoablative therapies including ethanol, hypertonic saline, and acetic acid solutions as well as gels in a porcine renal model. MATERIALS AND METHODS A MEDLINE search was performed for articles on animal and human tissue chemoablation published since 1965. In addition, at Washington University, experimental chemoablation was performed in pigs with 95% ethanol (4 mL), 24% hypertonic saline (4 mL), or 50% acetic acid (4 mL) solutions as well as in gel form. RESULTS There is extensive literature on the use of chemoablation for liver metastases; recently, chemoablation of the prostate has become an area of research. Human studies have been limited to patients who are not surgical candidates or to investigational procedures performed prior to definitive prostatic surgery. Animal studies of renal chemoablation as a sole therapy have produced mixed results. In our studies, only acetic acid provided complete necrosis. CONCLUSIONS To date, ethanol chemoablation has been shown to be feasible and reproducible only for metastatic hepatic carcinoma. In urology, chemoablation is still very much in the investigational stage for both the prostate and the kidney. A significant drawback is that even in the gel form, the spread of the chemoablative substance through the tissue is irregular and unpredictable. In the future, chemoablation may become a more effective modality by combining it with radiofrequency or other energy sources.

Abstract
A injeção percutânea de etanol (IPE) guiada por ultra-som tem sido utilizada para o tratamento de nódulos tiroidianos autônomos, sólidos e císticos. Apresentamos nossa experiência em 50 pacientes tratados, sendo 26 portadores de nódulos sólidos, 17 de nódulos císticos e 7 de nódulos autônomos (NA). Avaliamos os pacientes 1 semana, 1 mês, 3 meses, 6 meses e 1 ano após a IPE. Após 1 ano, os nódulos sólidos reduziram a 74% do volume inicial, os císticos diminuíram 92% sem apresentar recidivas. Um ano após o tratamento dos nódulos autônomos, 5 pacientes estavam em eutiroidismo clínico e laboratorial e 2 em eutiroidismo mas com TSH subnormal. Não houve recorrência da tirotoxicose e a redução nodular foi de 66%. O procedimento foi bem tolerado por todos. Os resultados confirmam que a IPE é uma boa alternativa terapêutica para redução dos nódulos tiroidianos císticos e sólidos e no tratamento dos nódulos autônomos.

Abstract
BACKGROUND: Autonomous thyroid nodules can be treated by a variety of methods. We assessed the efficacy of percutaneous ethanol injection in treating autonomous thyroid nodules. METHODS: 35 patients diagnosed by technetium-99 scanning with hyperfunctioning nodules and suppressed sensitive TSH (sTSH) were given sterile ethanol injections under ultrasound guidance. 29 patients had clinical and biochemical hyperthyroidism. The other 6 had sub-clinical hyperthyroidism with suppressed sTSH levels (<0.24 &mgr;IU/ml) and normal thyroid hormone levels. Ethanol injections were performed once every 1-4 weeks. Ethanol injections were stopped when serum T3, T4 and sTSH levels had returned to normal, or else injections could no longer be performed because significant side effects. Patients were followed up at 3, 6 and, in 15 patients, 24 months after the last injection. RESULTS: Average pre-treatment nodule volume [18.2 PlusMinus; 12.7 ml] decreased to 5.7 PlusMinus; 4.6 ml at 6 months follow-up [P < 0.001]. All patients had normal thyroid hormone levels at 3 and 6 months follow-up [P < 0.001 relative to baseline]. sTSH levels increased from 0.09 PlusMinus; 0.02 &mgr;IU/ml to 0.65 PlusMinus; 0.8 &mgr;IU/ml at the end of therapy [P < 0.05]. Only 3 patients had persistent sTSH suppression at 6 months post-therapy. T4 and sTSH did not change significantly between 6 months and 2 years [P > 0.05]. Ethanol injections were well tolerated by the patients, with only 2 cases of transient dysphonia. CONCLUSION: Our findings indicate that ethanol injection is an alternative to surgery or radioactive iodine in the treatment of autonomous thyroid nodules.

Abstract
This paper reports macro- and microscopic changes in hyperfunctioning thyroid nodules (HTN), initially diagnosed as solitary, in patients treated with percutaneous ethanol injection (PEI). In 78 patients, benign solitary HTN were diagnosed by clinical and hormonal examination. High resolution ultrasonography confirmed the solitary nodule. The results of fine needle aspiration biopsy (FNAB), performed twice, ruled out malignancy of the nodule. The patients were referred for PEI treatment. At 1-year follow-up, newly formed thyroid nodules, whose volumes increased, were detected in five patients (6.4%) with HTN, initially diagnosed as solitary. Therefore, these patients were operated on. Subtotal thyroidectomy was performed. At the intraoperative macroscopic evaluation, a hard fibrous solid mass was found in place of three nodules (n1, n2, n3) following PEI treatment. The middle area of the cut surface of PEI-treated nodules (n4 and n5) in the other two patients was firm and haemorrhagic, surrounded by a fibrous mass. Histolopathologic examination of n1, n2 and n3 revealed fibrosis and hyalinosis. Examination of n4 and n5 showed haemorrhagic necrosis in the middle of the nodules surrounded by fibrous tissue.

Abstract
PURPOSE To evaluate percutaneous interstitial laser photocoagulation (ILP) as a palliative treatment of recurrent thyroid carcinoma untreatable with surgery or radioiodine administration. MATERIALS AND METHODS By using 18 resected thyroid glands, the volume and histologic pattern of ILP-induced thyroid damage were assessed. In vivo treatment feasibility was evaluated by using a low-energy laser in two volunteers before thyroidectomy for huge autonomously functioning nodules. With ultrasonographic (US) monitoring, a 21-gauge spinal needle was inserted into the thyroid nodules. A 300-microm quartz fiberoptic guide was inserted through the needle lumen, and the fiber tip was placed in direct contact with the tissue. Laser irradiation was performed with a 1.064-nm Nd:YAG laser in surgically resected glands, which were treated with 2, 3, 5, or 7 W. RESULTS Tissue ablation was well-defined histologically, and its area was related to laser irradiation parameters (range, 0-26 mm). No correlation was found between US images and the actual extent of laser-induced lesions. Large colloid or fluid collections did not permit regular heat diffusion within the tissue. In vivo low-energy ILP was performed without technical difficulties or complications. CONCLUSION ILP induces well-defined tissue ablation correlated with energy parameters in thyroid glands devoid of cystic areas. ILP could be a therapeutic tool for highly selected problems in thyroid tumor treatment.

Abstract
PURPOSE To verify the effectiveness of percutaneous ethanol injection (PEI) in the treatment of large (>30-mL) hyperfunctioning thyroid nodules. MATERIALS AND METHODS Twelve patients (eight women, four men; age range, 26-76 years) with a large hyperfunctioning thyroid nodule (volume range, 33-90 mL; mean, 46.08 mL) underwent PEI treatment under ultrasonographic (US) guidance. US was used to calculate the volume of the nodules and to assess the diffusion of the ethanol in the lesions during the procedure. When incomplete necrosis of the nodule was depicted at scintigraphy performed 3 months after treatment, additional PEI sessions were performed. RESULTS Four to 11 PEI sessions (mean, seven) were performed in each patient, with an injection of 3-14 mL of 99.8% ethanol per session (total amount of ethanol per patient, 30-108 mL; mean, 48.5 mL). At scintigraphy after treatment in all patients, recovery of extranodular uptake, absence of uptake in the nodule, and normalization of thyroid-stimulating hormone (thyrotropin) levels were observed. In all patients, US showed volume reductions of 30%-50% after 3 months and 40%-80% after 6-9 months. Side effects were self-limiting in all patients. During the 6-48-month follow-up, no recurrence was observed. CONCLUSION PEI is an effective and safe technique for the treatment of large hyperfunctioning thyroid nodules.

Abstract
Power Doppler (PD) is a recent color-Doppler Ultrasound (US)-technique, which allows to detect the presence of flow even in very small vessels, providing a sort of angiographic micromap. The aim of this study was to evaluate whether percutaneous ethanol injection (PEI) outcome might be improved by injecting the ethanol into the nodule under PD assistance. Thus, 14 patients affected with pretoxic (PTA) and 8 with toxic adenoma (TA) were submitted to this alternative tool. Before PEI, all patients were submitted to a careful endocrinological study, including an US-guided fine-needle biopsy in order to exclude the presence of malignancy. In addition, all the nodules were evaluated at PD-US and their vascular patterns were recorded on videotape and compared with those obtained after treatment. The procedure consisted of slow injection of sterile ethanol under direct PD-US control. The number of PEI sessions was 2.3+/-0.1 in PTA and 3.0+/-0.3 in TA. All patients were also evaluated 3, 6, 12 and 18 months after PEI. Successful therapy was considered when normalization of thyroid hormones and TSH was achieved together with the disappearance of nodular hyperactivity and complete recovery of extra-nodular tracer uptake at scintigraphy. PEI was tolerated very well by all patients. The most common side effect was a transient local or irradiated pain. All patients with PTA and 6 out of 8 patients with TA were successfully treated. In these cases, PD-US showed the progressive reduction of the intranodular blood flow, up to its extinction after 6-12 months, with the presence of little perilesional vascular spots. Nodular shrinkage was obtained in all patients (from 4.7+/-0.7 to 1.1+/-0.4 ml in PTA and from 21.0+/-2.8 to 6.2+/-1.6 ml in TA). In conclusion, PD assistance improves PEI procedure, since it allows to guide the ethanol injection towards the principal afferent vessels of the nodules and to monitor the diffusion and the effects of ethanol on nodular vascularization.

Abstract
Solitary toxic adenoma and toxic multinodular goiter are very common forms of thyrotoxicosis around the world. Advances in molecular biology and genetics have led to new insights into the pathogenesis of these disorders. Current theories on autonomy in the thyroid are discussed in this article. The therapeutic roles of surgery, radioiodine ablation, and percutaneous ethanol administration also are reviewed.

Abstract
Ultrasound-guided ethanol injection (PEI) is an effective treatment of autonomously functioning thyroid nodules (AFTN) but little is known about the tissue lesions induced by alcohol. We report morphological changes of an AFTN which was removed after successful PEI treatment. At histological evaluation, the adenoma showed multiple areas of coagulative necrosis with eosinophilic ghost follicles, hemorrhages, small vessel thrombosis and a wedge-shaped hemorrhagic infarction. The peripheral adenomatous tissue and the surrounding thyroid parenchyma were free of regressive changes and/or lympho-monocytic inflammatory reactions. Enzyme histochemistry confirmed the hyperfunctioning character of the lesion and showed reduction of succinic dehydrogenase and cytochrome-c-oxydase activity in the viable tissue surrounding the central necrotic areas. By electron microscopy, the hyperfunctioning follicular epithelium showed submicroscopical alterations of the adenomatous cells surrounding the areas of coagulative necrosis. These results suggest that control of hyperthyroidism, after PEI, is due to: a) directly induced, irreversible damage (coagulative necrosis and vascular thrombosis with hemorrhagic infarction) in the central areas of the lesion; b) potentially reversible damage (reduction of intracellular enzyme activity and ultrastructural changes) in the peripheral areas.

Abstract
Four patients with solitary autonomously functioning thyroid nodule (AFTN; 2 toxic and 2 subclinically toxic) received ultrasonography (US)-guided percutaneous ethanol injection therapy (PEIT). The pretreatment scintigraphic appearance of the nodule was hot, and radioactivity in the extranodular tissue was completely suppressed throughout. Ninety-nine percent ethanol was slowly injected under US guidance. As a rule, the injection was performed in fractionated sessions and the treatment was repeated until the total amount of ethanol exceeded the baseline nodular volume. The therapy was successful. Complete remission of hyperthyroidism was observed among the patients with toxic nodule. The basal level of TSH and its response to TRH injection was normalized in the patients with subclinically toxic nodule. Posttreatment scintigrams revealed that the extranodular tissue recovered and radioactivity in the hot nodule had noticeably decreased. The rate of reduction in the nodular volume was more than 80% in all. There was no recurrence or development of hypothyroidism during a follow up of 10 to 23 months. The main side effect was mild and transient pain and/or a burning sensation at injection. No severe or permanent complications occurred. Although the number of our cases was small, the results suggest that PEIT is a useful program in treating AFTN.

Abstract
Some aspects of thyroid nodule evaluation and management remain controversial. Radionuclide scanning provides functional information about nodules and differentiates cold from hot nodules. Although thyroid cancers are cold on scan, most cold nodules are benign. Ultrasonography visualizes the thyroid gland and nodules with remarkable clarity and provides structural information about location, number, size, and consistency of nodules. Widespread application of ultrasonography has resulted in the frequent discovery of incidental (occult) nodules in the general population. The clinical significance of these nodules remains unknown, and their management has created a dilemma for physicians. Current cost-effective evaluation of nodules does not include scanning or ultrasonography as routine frontline tests. In most centers, fine-needle aspiration biopsy has supplanted imaging studies as the routine initial procedure for differentiating benign from malignant nodules. Cytologic diagnosis is reliable and inexpensive, and it results in a better selection of patients for surgery. Limitations include false-negative diagnoses, nondiagnostic results, and indeterminate "suspicious" results. Laboratory test results are usually normal, but determination of serum thyrotropin may identify a hot nodule, and plasma calcitonin may help diagnose medullary thyroid carcinoma. Treatment of thyroid nodules is controversial. In some practices, benign colloid nodules are treated with suppressive doses of levothyroxine. Recent reports cast doubt on the efficacy of this approach, and it is no longer acceptable to select patients for surgical treatment on the basis of suppressive therapy. Furthermore, suppressive levothyroxine therapy may be associated with significant bone and cardiac side effects, especially in elderly patients and postmenopausal women. Our approach is observation for most patients, and we suggest a careful risk-benefit analysis when suppression is considered. Hot (autonomous) nodules can be treated with radioiodine, surgery, or ethanol injection. The use of sensitive thyrotropin assays has revealed that the "euthyroid" hot nodule is often associated with subclinical hyperthyroidism, warranting treatment if risks of osteoporosis are significant. Small (< 1.5 cm) occult nodules can be observed. Larger (> 1.5 cm) nodules can be selectively evaluated by ultrasonographically guided fine-needle aspiration. It is prudent to consider cost of care, risk-benefit analysis, and the low incidence of malignancy in thyroid nodules when diagnostic tests are selected and the treatment plan is outlined.

Abstract
Ultrasound-guided percutaneous ethanol injection (PEI) was first proposed by Livraghi in 1990 as a possible therapy for autonomously functioning thyroid nodules (AFTN). The procedure is performed on out-patients; is rapid; there is no need of anesthesia, nor of bed rest or patient observation after treatment. Under direct sonographic control a limited amount of 95% sterile ethanol (1-5 ml) is slowly injected into the nodule. In predominantly cystic nodules complete fluid removal is preliminarily performed, and thereafter ethanol is injected on the basis of the aspirated fluid volume without removing the needle. PEI-induced thyroid damage is characterized by coagulative necrosis and haemorrhagic infarction due to vascular thrombosis, and is well defined from the surrounding thyroid parenchyma. Several papers have confirmed the effectiveness of PEI. Normalization of serum TSH and thyroid hormones, marked decrease of nodule volume, and effacement of the previously hyperfunctioning area at thyroid scintiscan are reported in 64-85% of toxic AFTN. Nontoxic AFTN are successfully treated in 80-100% of the cases. PEI significantly superior to aspiration alone in inducing volume reduction of benign cystic thyroid nodules, and the recurrence rate is only 2.5-5%. Complications requiring hospitalization were not reported, but the importance of experienced operators must be stressed to avoid transient dysphonia due to recurrent laryngeal nerve damage. Prior to PEI malignancy must be ruled out by fine needle aspiration in all patients. Radioiodine and surgery remain the treatments of choice of large toxic thyroid nodules, but PEI can be effectively used in selected cases.(ABSTRACT TRUNCATED AT 250 WORDS)
