Abstract
Thyroid diseases are relatively common in clinical practice. Surgery and use of related drugs may exacerbate the underlying thyroid diseases, increasing the difficulty of perioperative management. However, there is a lack of guidelines and consensus for non-thyroid surgery in patients with thyroid dysfunction. This review mainly summaries the perioperative management of non-thyroid surgery in patients with hypothyroidism and hyperthyroidism to provide clinical treatment suggestions and reduce the risk of perioperative complications.

Mortality After Total Thyroidectomy for Amiodarone-Induced Thyrotoxicosis According to Left Ventricular Ejection Fraction. Otolaryngol Head Neck Surg 2023; 169:1542-1549. [PMID: 37317630 DOI: 10.1002/ohn.405] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 04/28/2023] [Accepted: 05/13/2023] [Indexed: 06/16/2023]
Abstract
OBJECTIVE To report cardiac outcomes after total thyroidectomy for amiodarone-induced thyrotoxicosis according to the baseline left ventricular ejection fraction in a tertiary referral center. STUDY DESIGN Retrospective, monocentric. SETTING The tertiary health care system. METHODS Patients who underwent total thyroidectomy for amiodarone-induced thyrotoxicosis between 2010 and 2020 with age >18 and available preoperative left ventricular ejection fraction were included in this study. Patients were dichotomized into: group 1 with left ventricular ejection fraction ≥40% (mildly reduced/normal ejection fraction), and group 2 with left ventricular ejection fraction <40% (reduced ejection fraction). RESULTS There were 34 patients in group 1 and 17 to group 2. The latter were younger (median 58.4 [Q1-Q3 48.0-64.9] vs. 69.8 years in group 1 [59.8-78.3], p = .0035) and they presented more cardiomyopathy (58.8 vs. 26.5%, p = .030). Overall, the median time until surgery referral was 3.1 [1.9-7.1] months and 47.1% underwent surgery after restoration of euthyroidism. Surgical complications accounted for 7.8%. In group 2, the median left ventricular ejection fraction was significantly improved after surgery (22.5 [20.0-25.0] vs. 29.0% [25.3-45.5], p = .0078). Five-year cardiac mortality was significantly higher in group 2 (p < .0001): 47.0% died of cardiac causes versus 2.9% in group 1. A baseline left ventricular ejection fraction <40% and a longer time until surgery referral were significantly associated with cardiac mortality (multivariable Cox regression analysis, p = .015 and .020, respectively). CONCLUSION These results reinforce the idea that surgery, if chosen, should be performed quickly in patients with left ventricular ejection fraction <40%.

Abstract
OBJECTIVE To identify variables that are associated with poor compliance to thyroid hormone replacement therapy in children after total thyroidectomy. METHOD A retrospective cohort study of children who underwent total thyroidectomy by high-volume pediatric otolaryngologists between 1/2014 and 9/2021. Postoperative poor compliance was characterized by at least three separate measurements of high TSH levels not associated with radioactive iodine treatment. RESULTS There were 100 patients, ages 3-20 years old who met inclusion criteria; 44 patients underwent thyroidectomy for cancer diagnosis, and 56 for Graves' disease. The mean follow-up time was 36.5 months (range 3.0-95.6 months). Overall, 42 patients (42%) were found to have at least three measurements of high TSH during follow-up, and 29 patients (29%) were diagnosed with clinical hypothyroidism. Sex, race, income, insurance type, and benign versus malignant etiology for thyroidectomy were not associated with adherence to therapy. Multivariate regression analysis identified patients with Graves' disease and hyperthyroidism at the time of surgery and Hispanic ethnicity to be associated with postoperative clinical hypothyroidism (OR 9.38, 95% CI 2.16-49.2, p = 0.004 and OR 6.15, 95% CI 1.21-36.0, p = 0.033, respectively). CONCLUSIONS Preoperative hyperthyroidism in patients with Graves' disease and Hispanic ethnicity were predictors of postoperative TSH abnormalities. Preoperative counseling for patients and their families on the implications of total thyroidectomy and the need for life-long medications postoperatively is necessary. Efforts should be made to evaluate and improve adherence to therapy pre-and postoperatively in patients with Graves' disease. LEVEL OF EVIDENCE 4 Laryngoscope, 133:2402-2406, 2023.

Abstract
RATIONALE Secondary hyperparathyroidism was one of mineral and bone disorders owing to chronic kidney disease. Patients who suffer from secondary hyperparathyroidism would receive medical treatment or parathyroidectomy with or without autotransplantation (AT). However, some patients receiving parathyroidectomy with AT have recurrent hyperparathyroidism, which impacts their lives. Patients with recurrent hyperparathyroidism may present persistent hypercalcemia and hyperphosphatemia, which would cause cardiovascular disease, like atherosclerosis. PATIENT CONCERNS A 63-year-old female of Asian descent with chronic kidney disease who suffered from recurrent hyperparathyroidism for twice. The patient underwent parathyroidectomy with AT in the left thigh when secondary hyperparathyroidism happened. After 3 months, recurrent hyperparathyroidism happened. DIAGNOSIS The patient was diagnosed with recurrent hyperparathyroidism due to chronic kidney disease with hyperparathyroidism status post parathyroidectomy with AT in the left thigh. Our patient also suffered from mineral and bone disorder. INTERVENTION Two parathyroid adenoma in the left thigh were found. However, one of them was too small to found in the operation. Therefore, autograftectomy of the large one was performed. However, hyperparathyroidism happened again. This time, the autograftectomy was performed under dual phase Tc-99m MIBI (99m Tc-methoxy isobutyl isonitrile) parathyroid scintigraphy and it succeeded. OUTCOMES After secondary autograftectomy, the value of intact parathyroid hormone was surveyed immediately and dropped by two-third followed by gradual reduction in the following weeks. The calcemia and phosphatemia were back to normal gradually. LESSONS In our case, importance of scintigraphy in the parathyroidectomy was confirmed.

Abstract
BACKGROUND Graves' disease (GD) is the most common cause of childhood hyperthyroidism. Surgery is often chosen as a treatment modality given the high relapse rates and side effects of antithyroid drugs and has shown to be safe and efficacious. The goal of our study was to evaluate whether hyperthyroidism at time of thyroidectomy is associated with higher intra and postoperative complication rates. METHODS A retrospective cohort study of children who underwent thyroidectomy for GD by high-volume pediatric otolaryngologists between 2014 and 2021. RESULTS 64 patients met inclusion criteria. Patients with hyperthyroidism (defined as free T4≥1.63 ng/dL) were more likely to be treated with beta-blocker preoperatively compared to the euthyroid group (20/24 patients (83%) vs 23/40 patients (58%) respectively, p = 0.035). Twenty (83%) patients with hyperthyroidism and 39 euthyroid patients (98%) were treated with methimazole prior to surgery. Intraoperative tachycardia was noted in 5% of euthyroid patients and 20.8% of patients with hyperthyroidism. The mean peak heart rate intra-operatively and the number of patients with heart rate ≥120bmp were significantly higher for patients with hyperthyroidism (96.5 ± 16.2 vs 87.6 ± 22.1bpm, p = 0.02). Two patients required administration of esmolol during surgery for heart rate control, both with hyperthyroidism. Intra-operative peak systolic blood pressure, operative time, estimated blood loss, persistent hypocalcemia, length of admission and recurrent laryngeal nerve paralysis rates were similar among groups. CONCLUSIONS Hyperthyroidism at surgery is associated with increased heart rate intraoperatively, with no increased risk for other complications. While optimizing thyroid hormone levels before surgery should be pursued in all children, our data suggest that hyperthyroidism should not delay the surgery.

Abstract
A woman in her mid-20s who was clinically euthyroid presented with an ostium secondum atrial septal defect for closure. Preoperatively, heart rate ranged from 80 to 110 beats per minute. On the day of surgery, heart rate was 120 beats per minute, which settled after induction. During ultrasound guided central line access, a thyroid swelling was noticed. 20-30 min after commencement of the surgery, heart rate increased up to 130 beats per minute. Since other causes of tachycardia was ruled out, an intraoperative blood sample for thyroid function test was sent. Esmolol was kept ready in case the swelling turned out to be hyperfunctioning thyroid nodule. Post bypass, the patient again developed tachycardia. The thyroid function test showed elevated T3, T4 and a mildly elevated TSH (Thyroid stimulating hormone) value, consistent with an extrathyroid source. The patient is on long-term follow-up under an endocrinologist. Postoperatively, she is again euthyroid and heart rates have settled to less than 100 beats per minute.

Abstract
In recent years, no major advances have been developed in the standard treatment of primary hyperthyroidism, which mainly includes medication, radiotherapy and bilateral subtotal/total thyroidectomy. These three therapies have specific advantages and disadvantages, even traditional surgery is not appropriate for some patients due to invasive trauma, complications and neck scars. As great progresses of thermal ablation technology have been made, many domestic hospitals are carrying out this technique for hyperthyroidism. In order to improve the efficacy and safety, critical issues related to thermal ablation in patients with hyperthyroidism, including indications, contraindications, perioperative preparations, anesthesia and procedure etc, were discussed. The Chinese Medical Doctor Association, Ultrasound Intervention Professional Committee of Interventional Physician Branch of Chinese Medical Doctor Association, Professional Committee of Interventionist Branch of Chinese Medical Doctor Association, The Expert Committee of the Chinese Society of Clinical Oncology (CSCO) and the Professional Committee of the Chinese Anti-Cancer Association organized related experts and formulated this consensus based on the latest research progress.

Abstract
CONTEXT Limited studies have focused on the impact of subclinical hyperthyroidism (SHyper) on poor prognosis in patients with known coronary artery disease (CAD). OBJECTIVE We implemented the present study to explore the association between SHyper and adverse cardiovascular events in CAD patients who underwent drug-eluting stent implantation. METHODS We consecutively recruited 8283 CAD patients undergoing percutaneous coronary intervention (PCI). All subjects were divided into 2 groups according to their thyroid function: group 1 (euthyroidism group, n = 7942) and group 2 (SHyper group, n = 341). After 1:4 propensity score (PS) matching, 1603 patients (332 SHyper group and 1271 euthyroidism group) were selected. The primary endpoint was major adverse cardiovascular events (MACEs), a composite of cardiac mortality, nonfatal myocardial infarction (MI), and target vessel revascularization (TVR). RESULTS Kaplan-Meier (K-M) survival analyses suggested that there was no significant difference in the primary endpoint and secondary endpoints (MACE: 11.4% vs 8.8%, log-rank P = .124; cardiac death: 1.2% vs 0.9%, log-rank P = .540; nonfatal MI: 5.7% vs 4%, log-rank P = .177; and TVR: 6% vs 4.7%, log-rank P = .303) in the PS-matched population. Cox regression analysis indicated that SHyper was not an independent risk factor for MACEs (HR 1.33, 95% CI 0.92-1.92, P = .127). CONCLUSION SHyper is not independently associated with adverse cardiovascular events in CAD patients undergoing PCI. More studies should be implemented in the future to assess the long-term predictive value of SHyper with thyrotropin levels <0.1 mIU/L for CAD patients undergoing PCI.

Abstract
Background The relationship between good early control of thyroid hormone levels after thyroidectomy for Graves’ disease (GD) and subsequent risks of mortality and morbidities is not well known. The aim of this study was to examine the association between thyroid hormone levels within a short interval after surgery and long-term mortality and morbidity risks from a population-based database. Methods Patients with GD who underwent complete/total thyroidectomy between 2006 and 2018 were selected from the Hong Kong Hospital Authority clinical management system. All patients were classified into three groups (euthyroidism, hypothyroidism, and hyperthyroidism) according to their thyroid hormone levels at 6, 12, and 24 months after surgery. Cox proportional hazards models were performed to compare the risks of all-cause mortality, cardiovascular disease (CVD), Graves’ ophthalmopathy, and cancer. Results Over a median follow-up of 68 months with 5709 person-years, 949 patients were included for analysis (euthyroidism, n = 540; hypothyroidism, n = 282; and hyperthyroidism, n = 127). The hypothyroidism group had an increased risk of CVD (HR = 4.20, 95 per cent c.i. 2.37 to 7.44, P < 0.001) and the hyperthyroidism group had an increased risk of cancer (HR = 2.14, 95 per cent c.i. 1.55 to 2.97, P < 0.001) compared with the euthyroidism group. Compared with patients obtaining euthyroidism both at 6 months and 12 months, the risk of cancer increased in patients who achieved euthyroidism at 6 months but had an abnormal thyroid status at 12 months (HR = 2.33, 95 per cent c.i. 1.51 to 3.61, P < 0.001) and in those who had abnormal thyroid status at 6 months but achieved euthyroidism at 12 months (HR = 2.52, 95 per cent c.i. 1.60 to 3.97, P < 0.001). Conclusions This study showed a higher risk of CVD in postsurgical hypothyroidism and a higher risk of cancer in hyperthyroidism compared with achieving euthyroidism early after thyroidectomy. Patients who were euthyroid at 6 months and 12 months had better outcomes than those achieving euthyroidism only at 6 months or 12 months. Attaining biochemical euthyroidism early after thyroidectomy should become a priority.

Abstract
RATIONALE Syndrome of inappropriate secretion of thyroid-stimulating hormone (SITSH) is a rare cause of hyperthyroidism. Thyroid-stimulating hormone (TSH) levels are usually normal or high, and triiodothyronine (FT3) and free thyroxine (FT4) levels are usually high in subjects with SITSH. PATIENT CONCERN A 37-year-old woman had experienced galactorrhea and menstrual disorder for a couple of years before. She had undergone infertility treatment in 1 year before, hyperthyroidism was detected and she was referred to our institution. DIAGNOSIS She was suspected of having SITSH and was hospitalized at our institution for further examination. The data on admission were as follows: FT3, 4.62 pg/mL; FT4, 1.86 ng/dL; TSH, 2.55 μIU/mL. Although both FT3 and FT4 levels were high, TSH levels were not suppressed, which is compatible with SITSH. In addition, in brain contrast-enhanced magnetic resonance imaging, nodular lesions were observed in the pituitary gland with a diameter of approximately 10 mm. In the thyrotropin-releasing hormone load test, TSH did not increase at all, which was also compatible with TSH-secreting pituitary adenoma. In the octreotide load test, the TSH levels were suppressed. Based on these findings, we diagnosed this subject as SITSH. INTERVENTIONS Hardy surgery was performed after the final diagnosis. In TSH staining of the resected pituitary adenoma, many TSH-producing cells were observed. These findings further confirmed the diagnosis of pituitary adenoma producing TSH. OUTCOMES Approximately 2 months after the operation, TSH, FT3, and FT4 levels were normalized. Approximately 3 months after the operation, she became pregnant without any difficulty. LESSONS We should consider the possibility of SITSH in subjects with galactorrhea, menstrual disorders, or infertility. In addition, we should recognize that it is very important to repeatedly examine thyroid function in subjects with galactorrhea, menstrual disorder, or infertility.

Abstract
Background: The American Thyroid Association (ATA) published the 2015 Management Guidelines for patients with thyroid nodules and differentiated thyroid cancer, recommending a shift to less aggressive diagnostic, surgical, and postoperative treatment strategies. At the same time and perhaps related to the new guidelines, there has been a shift to outpatient thyroid surgery. The aim of the current study was to assess physician adherence to these recommendations by identifying and quantifying temporal trends in the rates and indications for thyroid procedures in the inpatient and outpatient settings. Methods: Using the IBM® MarketScan® Commercial database, we identified employer-insured patients in the United States who underwent outpatient and inpatient thyroid surgery from 2007 to 2018. Thyroid surgery was classified as total thyroidectomy (TT), thyroid lobectomy (TL), or a completion thyroidectomy. The surgical indication diagnosis was also determined and classified as either benign or malignant thyroid disease. We compared outpatient and inpatient trends in surgery between benign and malignant thyroid disease both before and after the release of the 2015 ATA guidelines. Results: A total of 220,088 patients who underwent thyroid surgery were included in the analysis. Approximately 80% of TLs were performed in the outpatient setting versus 70% of TTs. Longitudinal analysis showed a statistically significant changepoint for TT proportion occurring in November 2015. The proportion of TT as compared with TL decreased from 80% in September 2015 to 39% by December 2018. For thyroid cancer, there is an increasing trend in performing TL over TT, increasing from 17% in 2015 to 28% by the end of 2018. Conclusions: There was a significant changepoint occurring in November 2015 in the operative and management trends for benign and malignant thyroid disease.

Abstract
PURPOSE Preoperative imaging in patients with primary hyperparathyroidism provides important localization information, allowing the surgeon to perform a focused surgery. However there are no evidence-based guidelines suggesting which preoperative imaging should be used, resulting in a risk of excessive prescription of exams and waste of economic resources. The main purpose of this study was to describe our experience on the performance of various imaging techniques for the preoperative localization of abnormal parathyroid gland/s, with a focus on the sensitivity and specificity of each technique. Secondly, we carried out an analysis of the cost utility of each technique in order to determine the most clinical and cost-effective combination of localization studies. MATERIALS AND METHODS Records of 336 patients who underwent parathyroidectomy were retrospectively examined comparing imaging and intraoperative/histopathologic findings to evaluate the accuracy in parathyroid detection of each imaging technique. Costs were determined by regional health system reimbursement. RESULTS We found that the sensitivity of color Doppler US was significantly higher than SPECT (p 0,023), while the sensitivity of 4D-CT was significantly better than US (p 0,029) and SPECT (p 0,0002). CONCLUSIONS In experienced hands color Doppler US is a highly sensitive technique especially in patients with no thyroid diseases. In patients with concomitant thyroid pathology, the combination of US and 4D-CT represents a reliable localization technique.

Abstract
COTI (collar therapy indicator) has been recently introduced for the detection of gamma rays with emphasis on thyroid investigations. The aim of this study was to test the feasibility of a prototype version of COTI including activity detectors with low sensitivity in performing thyroid uptake measurements for a large group of patients. Consequently, thyroid uptake tests were carried out for a total of 89 patients (22 males and 67 females; age: 44 ± 13 years) with thyroid cancer (n = 74), hyperthyroidism (n = 16) at 2 and 24 h after administration of 0.44-2 MBq of 131I. Eight individuals among the thyroid cancer patients were monitored up to 96 h after administration. The COTI device was equipped with two CsI (Tl) detectors, known as LoHi type, sensitive to activity ranges from 0.02 to 30 MBq of 131I. The uptake values from COTI were compared with those measured with a standard probe. It was found that the mean uptake of thyroid activity in thyroid cancer patients was 2.1 ± 1.3% at 2 h when measured with the standard probe, while it was 2.2 ± 1.2% when measured with COTI. In addition, the average uptake at 24 h after administration was 2.5 ± 3.2% and 3.2 ± 3.8% measured with COTI and the standard probe, respectively. A strong correlation was found at 24 h between the results obtained with COTI and the standard probe, while a weaker correlation was seen at 2 h. Overall, there was no significant difference between the results obtained with the standard probe and those obtained with COTI at both 2 and 24 h (Pvalue ≥ 0.05). Besides, 85% of the uptake values measured with COTI were less than those measured with the standard probe at the 24 h after administration. The average uptake value was 0.9 ± 0.8% after 96 h by COTI, and 1.4 ± 1.3% by the standard probe. Pertaining to the hyperthyroidism patients, COTI showed mean uptake values of 20 ± 16% and 23 ± 18% at 2 and 24 h, respectively. In contrast, the standard probe suggested higher mean uptake values of 26 ± 18% and 30 ± 22%, respectively. It is concluded that the prototype of COTI used in the present study has been proved to be a feasible and promising tool in thyroid investigations. It is noted, however, that the next COTI generation should include detectors equipped with collimator and energy discrimination.

Abstract
PURPOSE Redo thyroid surgery is associated with higher risk of hematoma than the initial thyroid surgery. We report a single surgeon's experience of performing redo thyroid surgery without drains. METHODS This retrospective single-institutional study evaluates the safety and efficiency of redo thyroid surgery without drains by comparing three groups of patients: those who underwent primary bilateral thyroidectomy (Group 1), those who underwent completion thyroidectomy (Group 2); and those who underwent thyroidectomy for recurrent thyroid diseases (Group 3). RESULTS The demographic characteristics did not differ among the groups. Substernal extension and hyperthyroidism were more frequent in group 1, whereas the weight of the resected thyroid gland was lower in groups 2 and 3. Hematoma occurred in 5%, 4%, and 4% of patients in Groups 1, 2, and 3, respectively. Postoperative transient hypocalcemia occurred in 19%, 16%, and 21% of patients in Groups 1, 2, and 3 respectively. The postoperative incidence of transient recurrent laryngeal nerve (RLN) paralysis in Groups 1, 2, and 3, was 6%, 7%, and 8%, respectively. The incidence of permanent unilateral RLN paralysis in Groups 2 and 3 was 1%. The postoperative length of stay was 1 day in 92% of the patients from all groups. CONCLUSIONS Avoiding the routine use of drains in redo thyroid surgery is safe and effective, it does not increase overall surgical morbidity, and it reduces the overall length of stay in hospital.

Abstract
A 14-year-old neutered male cat was presented because of a left ventral cervical mass. Based on imaging, the mass was suspected to have a thyroid origin. There was no evidence of gross metastatic disease or hyperthyroidism. Left thyroidectomy alone was the treatment for this patient and a thyroid carcinoma was diagnosed on histopathology. At last follow-up, 831 days after surgery, there was suspicion of metastasis to the lungs and the cat had developed a right thyroid mass and hyperthyroidism. Key clinical message: This case report identifies a non-hypersecretory thyroid carcinoma. This is a rare diagnosis. The outcome with surgery alone was comparable to that reported for treatment with iodine131.

Abstract
BACKGROUND Prior to thyroidectomy for hyperthyroidism, it is recommended that patients are managed with antithyroid drugs (ATDs) and rendered euthyroid to decrease the risk of thyroid storm. However, not all patients tolerate ATD and the risk of thyroid storm during thyroidectomy in these patients is unclear. Therefore, the aim of this study was to compare the management and outcomes of hyperthyroid patients that were on ATDs prior to surgery to those who were not. STUDY DESIGN A prospectively maintained, single-institution database was queried for all hyperthyroid patients who were initially treated with ATDs and underwent thyroidectomy from January 1, 2012, to June 18, 2018. Patients were divided into two groups: (1) those on ATDs at surgery (ATD group) and (2) those who could not tolerate and stopped ATDs prior to surgery (no-ATD group). Demographic and clinical data were collected. Primary outcomes were readmissions/emergency department visits and postoperative complications within 30 days of thyroidectomy. RESULTS Of the 248 patients, 231 were in the ATD group and 17 (7%) were in the no-ATD group. There were no mortalities or thyroid storm events in either group. There was no difference in Clavien-Dindo Grade 2 or 3 complications between the two groups. There were no ED visits or 30-day readmissions in the no-ATD group compared to 17 (7%) events in the ATD group (p = 1.0). CONCLUSION While it is preferable to render patients euthyroid prior to thyroidectomy for hyperthyroidism, results of this study suggest that when patients cannot tolerate ATDs, it is possible to perform thyroidectomy without increased risk of thyroid storm or intra- and postoperative complications.

Abstract
The ongoing spread of the coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) poses a significant threat to global health. As the coronavirus outbreak began spreading, hospitals were forced to relocate resources to treat the growing number of COVID-19 patients. As a consequence, doctors across the country canceled tens of thousands of nonurgent surgeries. However, recognizing that the COVID-19 situation may be highly variable and fluid in different communities across the country, elective surgery could be still allowed in some centers for patients included in the high-priority class. The majority of endocrine disorders requiring surgical treatment in patients identifiable as first-priority class, or needing hospitalization within 30 days, are generally represented by malignant thyroid tumors, hyperthyroidism, hyperparathyroidism, and some adrenal disorders. The need for urgent intervention is evaluated on a case-by-case basis according to the severity of the symptoms, the likelihood of progression, and global clinical judgment. On the basis of the above indications, during the last 4 weeks, we performed 18 planned surgical treatments in patients with thyroid cancer (total thyroidectomies, plus lymph node dissection if needed) or multinodular toxic goiter. In no case, postoperative ventilatory support was needed, and the average hospital stay was 3 days. The negative COVID-19 status for all the treated patients was appropriately evaluated beforehand. Nobody knows how long the current COVID-19 pandemic will be lasting. Certainly, we will be requested in the next future to incrementally offer surgical services for endocrine disorders that have been deferred for the COVID-19 pandemic.

Abstract
OBJECTIVE Hyperthyroidism is a group of diseases with many different etiologies and clinical manifestations. The most common causes include toxic multi-nodular goiter, Graves' disease and toxic adenoma. The prevalence of thyroid cancer developing in patients with hyperthyroidism has gradually increased in recent years. The aim of this study is to detect the incidental thyroid cancer rates in patients who have undergone a surgical operation due to hyperthyroidism, and to specify the patient groups in whom surgical treatment should come into the foreground. METHODS A total of 591 patients, who had surgical excision of the thyroid due to hyperthyroidism between January 2007 and June 2017, were retrospectively analyzed. RESULTS Of all the patients included in the study, 377 (63.7%) had multi-nodular goiter, 132 (22.3%) had Graves' disease, 55 (9.4%) had nodular Graves' disease, and 27 (4.6%) had toxic adenoma. Thyroid cancer was determined in 131 out of 591 patients (22.6%) who were operated. The most common histologic type was thyroid micropapillary carcinoma (65/131; 49.6%). The accompanying pathologies to thyroid cancer were as follows: Toxic multi-nodular goiter (89/131; 67.9%), nodular Graves' disease (24/131; 18.3%), Graves' disease (13/131; 9.9%) and toxic adenoma (5/131; 2.8%). DISCUSSION Prevalence of cancer on a background of hyperthyroidism has gradually increased in recent years. It is not realistic to determine thyroid cancer prevalence only based on autopsy examinations. This rate significantly increases in the presence of nodule in clinical studies. Most of the carcinomas are microcarcinomas that do not have lymphovascular invasion and have very low lymph node metastasis. Thus, their treatment is still under debate. KEY WORDS Hyperthyroidism Micropapillary Cancer, Thyroid cancer.

Abstract
Whether or not Graves' hyperthyroidism can be really cured, depends on the definition of "cure." If eradication of thyroid hormone excess suffices for the label "cure," then all patients can be cured because total thyroidectomy or high doses of ¹³¹I will abolish hyperthyroidism albeit at the expense of creating another disease (hypothyroidism) requiring lifelong medication with levothyroxine. I would not call this a "cure," which I would like to define as a state with stable thyroid stimulating hormone (TSH), free thyroxine, and triiodothyronine serum concentrations in the normal range in the absence of any thyroid medication. Surgery and radioiodine are unlikely to result in so-defined cures, as their preferable aim as stated in guidelines is to cause permanent hypothyroidism. Discontinuation of antithyroid drugs is followed by 50% recurrences within 4 years; before starting therapy the risk of recurrences can be estimated with the Graves' Recurrent Events After Therapy (GREAT) score. At 20-year follow-up about 62% had developed recurrent hyperthyroidism, 8% had subclinical hypothyroidism, and 3% overt hypothyroidism related to TSH receptor blocking antibodies and thyroid peroxidase antibodies. Only 27% was in remission, and might be considered cured. If the definition of "cure" would also include the disappearance of thyroid antibodies in serum, the proportion of cured patients would become even lower.

Abstract
BACKGROUND Hyperthyroidism is known to have a significant impact on quality of life (QoL), at least in the short term. The purpose of the present study was to assess QoL in patients 6-10 years after treatment for Graves' disease (GD) with radioiodine (RAI) compared to those treated with thyroidectomy or antithyroid drugs (ATD) as assessed with both thyroid-specific Thyroid-Related Patient-Reported Outcome (ThyPRO) questionnaire and general (36-item Short Form Health Status) QoL survey. METHODS The study evaluated 1186 GD patients in a sub-cohort from an incidence study 2003-2005 who had been treated according to routine clinical practice at seven participating centers. Patients were included if they had returned the ThyPRO (n = 975) and/or the 36-item Short Form Health Status survey questionnaire (n = 964) and informed consent at follow-up. Scores from ThyPRO were compared to scores from a general population sample (n = 712) using multiple linear regression adjusting for age and sex as well as multiple testing. Treatment-related QoL outcome for ATD, RAI, and surgery were compared, including adjustment for the number of treatments received, sex, age, and comorbidity. RESULTS Regardless of treatment modality, patients with GD had worse thyroid-related QoL 6-10 years after diagnosis compared to the general population. Patients treated with RAI had worse thyroid-related and general QoL than patients treated with ATD or thyroidectomy on the majority of QoL scales. Sensitivity analyses supported the relative negative comparative effects of RAI treatment on QoL in patients with hyperthyroidism. CONCLUSIONS GD is associated with a lower QoL many years after treatment compared to the general population. In a previous small randomized controlled trial, no difference was found in patient satisfaction years after ATD, RAI, or surgery. Now, it is reported that in a large non-randomized cohort, patients who received RAI had adverse scores on ThyPRO and 36-item Short Form Health Status survey. These findings in a Swedish population are limited by comparison to normative data from Denmark, older age, and possibly a more prolonged course in those patients who received RAI, and a lack of information regarding thyroid status at the time of evaluation. The way RAI may adversely affect QoL is unknown, but since the results may be important for future considerations regarding treatment options for GD, they need to be substantiated in further studies.

Abstract
INTRODUCTION Nodular goiter is the most common disorder of the thyroid gland. Less than total thyroidectomy procedures are considered the gold standard in the surgical management of nodular thyroid disease despite its propensity for recurrence. The aim of the study was to assess long-term sequelae of the less than total thyroidectomy procedures. MATERIAL AND METHODS In this single-center retrospective study, records of 154 patients that underwent less than total thyroidectomy, for nodular disease and/or hyperthyroidism between 1998 and 2013, were reviewed. Patients with malignant findings in the histology report and a follow-up of less than 5 years were excluded. RESULTS The mean age of the recorded patients was 65.1 ± 12.91 years of which 132 were females. Subtotal thyroidectomy was performed in 45.5% of the study population, 22.1% underwent partial thyroidectomy, while the remaining 32.5% underwent lobectomy. Long-term thyroxine supplementation was administered in 138 patients (89.6%). Recurrence of clinically important nodules (>1 cm) was observed in 68.2% of patients but only 11% of the population underwent completion thyroidectomy. In the univariate analysis, the duration of follow-up (p = 0.00005, C.I.: 0.903-0.965) as well as the type of operation (p = 0.035, C.I.: 1.031-2.348) appeared to have a significant correlation with nodular recurrence. The multivariate analysis identified the duration of follow-up (p = 0.0005, C.I.: 0.908-0.973) as the only significant predictive factor of nodular recurrence. CONCLUSION This is the first study with such a long duration of post-operative follow-up. The high rate of nodular recurrence in less than total thyroidectomy procedures along with the lifelong need for thyroxine supplementation suggest that a more conservative surgical approach is needed. When surgery is recommended, we suggest total thyroidectomy as the treatment of choice to avoid the recurrence of disease, the high cost associated with frequent follow-ups by means of sonography as well as thyroxine replacement therapy.
