Abstract
PURPOSE To investigate the parathyroid function and calcium (Ca) levels in the secondary hyperparathyroidism (SHPT) state in patients with Graves' disease. METHODS We examined 31 consecutive patients with Graves' disease without chronic kidney disease, who were treated with total thyroidectomy. The patients were divided into a normal parathyroid hormone (PTH) group (NPTH group; n = 19) with a PTH level ≤ 65 pg/mL, and a secondary hyperparathyroidism group (SHPT group; n = 12), with a PTH level > 65 pg/mL. The PTH and Ca-related parameters were examined and the risk factors for postoperative hypocalcemia were analyzed. RESULTS The preoperative Ca level was significantly lower (2.24 ± 0.06 vs. 2.31 ± 0.07 mmol/L, p < 0.05) in the SHPT group than in the NPTH group. The reduction in PTH, 1,25-dihydroxyvitamin D (1,25(OH)2D), and Ca levels from the preoperative day to the next morning was significantly greater in the SHPT group than in the NPTH group (p < 0.05). When intraoperative factors were included, the decrease in the PTH level alone was significant. SHPT was a significant factor in determining the extent of PTH reduction. CONCLUSIONS Hyperfunctioning parathyroid glands in the SHPT state were more susceptible to postoperative PTH reduction, which, combined with low preoperative Ca levels, increased the risk of postoperative hypocalcemia in patients with Graves' disease.

Abstract
To study the incidence and management of postoperative hypocalcemia in participants undergoing near-total (NTT) and total thyroidectomy (TT) at a tertiary health care center. This is an observational prospective study. Patients posted for NTT and TT in our institute and meeting the inclusion criteria were included. A total of 45 participants were enrolled. The serum calcium was measured on postoperative day 2, at the time of discharge and on 3 months follow-up. A combination of injectable and oral calcium supplements with or without vitamin D sachet was used for the treatment of hypocalcemia. Hypocalcemia was observed in 49% cases. Women were observed to develop hypocalcemia at a higher rate than men. Incidence of hypocalcemia was more in TT patients than NTT patients. Cases with malignant pathology were more susceptible to develop hypocalcemia than those with benign pathology. Operated TT with concomitant neck dissection were at higher risk for development of hypocalcemia. There was no significant association between age and incidence of hypocalcemia. Serum calcium measured on postoperative day 2 was a reliable indicator of risk of hypocalcemia. The early measurement of serum calcium level is a reliable indicator of the risk of hypocalcemia. Standardized treatment of hypocalcemic patients with calcium and vitamin D supplements can reduce the incidence and morbidity associated with postoperative hypocalcemia.

Abstract
BACKGROUND Post-operative hypoparathyroidism is the most frequent complication after total thyroidectomy. The identification of preoperative predictors could be helpful to identify patients at risk. This study aimed to evaluate the potential influence of preoperative PTH levels and their perioperative dynamics as a predictor of transient, protracted, and permanent post-operative hypoparathyroidism. METHODS A prospective, observational study that includes 100 patients who underwent total thyroidectomy between September 2018 and September 2020. RESULTS Transient hypoparathyroidism was present in 42% (42/100) of patients, 11% (11/100) developed protracted hypoparathyroidism, and 5% (5/100) permanent hypoparathyroidism. Patients who presented protracted hypoparathyroidism had higher preoperative PTH levels. The protracted and permanent hypoparathyroidism rate was higher in groups with greater preoperative PTH [0% group 1 (<40 pg/mL) vs. 5.7% group 2 (40-70 pg/mL) vs. 21.6% group 3 (>70 pg/mL); p = 0.03] and (0 vs. 8.3 vs. 20%; p = 0.442), respectively. The rate of protracted and permanent hypoparathyroidism was higher in patients with PTH at 24 h lower than 6.6 pg/mL and whose percentage of PTH decline was higher than 90%. The rate of transient hypoparathyroidism was higher in patients who showed a PTH decline rate of more than 60%. The percentage of PTH increase one week after surgery in patients with permanent hypoparathyroidism was significantly lower. CONCLUSION The prevalence of protracted hypoparathyroidism was higher in groups with higher preoperative PTH levels. PTH levels 24 h after surgery lower than 6.6 pg/mL and a decline of more than 90% predict protracted and permanent hypoparathyroidism. The percentage of PTH increase a week after surgery could predict permanent hypoparathyroidism.

Abstract
Thyroid storm is an acute life-threatening condition of hyperthyroidism that can present with cardiac failure, requiring extracorporeal membrane oxygenation (ECMO). We present the first case reported of total thyroidectomy successfully performed while on ECMO for thyroid storm in a 32-year-old male. This case highlights the challenges of managing refractory thyroid storm with multi-organ failure. We demonstrate that total thyroidectomy may still be safely performed while on ECMO for thyroid storm, if steps are taken to optimise the patient perioperatively, with careful surgical and anaesthesia planning.

Abstract
OBJECTIVE The McGill Thyroid Nodule Score (MTNS) is a preoperative tool used to predict the risk for well-differentiated thyroid cancer in adults. It was developed by a multidisciplinary team using established evidence-based risk factors for thyroid cancer. The modified McGill Thyroid Nodule Score (mMTNS) was developed to predict malignancy risk in children. A pilot study suggested the mMTNS was able to assess malignancy risk in children with indeterminate cytology on fine needle aspiration (FNA). This study seeks to validate these findings. METHODS Retrospective chart review identified subjects who underwent FNA biopsy and subsequent resection. Each patient was assigned a score to compare to final pathology. Statistical analysis was performed with SPSS. All tests were 2-tailed and statistical significance defined p < 0.05. Logistic regression used to determine predictive values of scores. RESULTS 46 patients ≤21 years of age underwent resection of a thyroid nodule. Female predominance of 85% (n = 39). 78% (n = 36) of patients had palpable nodule. 65% (n = 30) found to have benign pathology and 35% (n = 16) found to have malignancy. Malignant nodules associated with greater mean mMTNS compared to benign [13.63 vs 7.23]. An mMTNS greater >12 had sensitivity of 86.7%, specificity of 90.3%, positive predictive value of 81.3%, and negative predictive value of 93.3%. CONCLUSION Our data suggests the mMTNS continues to be a useful adjunct in predicting malignancy risk of pediatric thyroid nodules. An mMTNS >12 has a high risk for malignancy, which can aid in counseling and clinical decision making, particularly when there is indeterminate cytology on FNA. LEVEL OF EVIDENCE IV.

Abstract
INTRODUCTION Total thyroidectomy is the traditional primary approach for papillary thyroid cancer. However, recent evidence supports conservative management for low-risk tumors like papillary thyroid microcarcinomas (PTMCs). This study explores the adoption of these practices in our community, using a cancer database to analyze treatment strategies. METHODS A retrospective review of a 1433-patient institutional database identified 258 PTMC cases. Outcomes, including 30-day mortality, reoperation rate, postoperative hypocalcemia, and recurrent laryngeal nerve (RLN) injury, were assessed. RESULTS Of PTMC patients, 63.4% underwent total thyroidectomy, with higher rates of RLN injury (8.8% vs. 2.3%) and hypocalcemia (12.4% vs. 0.0%) compared to lobectomy. Non-endocrine surgeons had higher postoperative radioactive iodine administration rates (28.6% vs. 6.1%). Subgroup analysis revealed a shift in total thyroidectomy rates based on tumor size and surgery period. CONCLUSION Our community favors total thyroidectomy for PTMC, despite associated complications. Enhanced awareness and adherence to PTMC best practice guidelines are warranted.

Abstract
INTRODUCTION Hypoparathyroidism is the most common postsurgical complication of total thyroidectomy. Furthermore, it is the main cause of prolonged hospitalisation after this procedure. OBJECTIVE To predict the probability of post-thyroidectomy hypocalcaemia according to the levels of intact parathyroid hormone (iPTH), as well as to determine the needs for treatment with exogenous calcium according to the levels of serum calcium (Ca). MATERIALS AND METHODS Retrospective study was carried out on patients who underwent total thyroidectomy between January 2017 and January 2020 at Los Arcos del Mar Menor University Hospital (HULAMM). iPTH and Ca levels were measured at 4, 24 and 48 h after the surgery. Follow-up was 6 months. RESULTS Ninety-four patients were operated on. Temporary and permanent postoperative hypoparathyroidism percentages were, respectively, 51.06% and 6.38%. iPTH level 24 h after the procedure was the most reliable predictor of post-thyroidectomy temporary hypoparathyroidism (Area Under the ROC Curve (AUC) = 0.933, p < .001). iPTH levels ≥29 pg/mL predicted normal parathyroid metabolism. CONCLUSIONS The combined values of iPTH and Ca levels 24 h after thyroidectomy seems to be a reliable, safe and efficient method to control the post-thyroidectomy hypoparathyroidism. Our protocol could reduce the hospital stay of patients at low risk of hypocalcaemia, allowing them to be discharged from the hospital on the first postoperative morning and identifying patients at high risk of hypocalcaemia early.

Abstract
INTRODUCTION Obese patients often have higher complication rates after elective general surgeries; however, few studies have examined the outcomes after thyroidectomy. This study examines whether increased body mass index (BMI) is associated with poor postoperative outcomes after thyroid surgery. METHODS A retrospective review of patients who underwent thyroidectomy from 2015 to 2018 was performed. Demographics, comorbidities, pathology, and extent of resection (total versus hemithyroidectomy) were examined. Patients were classified into BMI groups according to the WHO definitions, and the incidence of surgical outcomes was determined in each group. Surgical outcomes of interest included readmission rates (RRs), length of stay, average operating room time, return to the operating room, hypocalcemia, postop infections, hematomas, and recurrent laryngeal nerve injury. Between-subjects statistics including independent samples t-test, ANOVA, and chi-square analyses were performed. RESULTS There were n = 465 patients included with a mean BMI 32.35 (standard deviation = 8.55) and median BMI 30.78 (Q1 = 26.26, Q3 = 36.73). There were no differences between BMI groups in age, gender, smoking, heart disease. There was a positive association between increased BMI and postoperative infection (P < 0.001), pneumonia (P = 0.018), and surgical site infection (P = 0.04), which were highest for BMI > 40. Increased BMI was associated with a higher 30-d RR (P = 0.008), particularly for BMI >40 versus BMI <40 (6.2% versus 1.05%; P = 0.003). There were no significant differences between surgical outcomes for patients with increased BMI who underwent total thyroidectomy or hemithyroidectomy. CONCLUSIONS Excellent postoperative outcomes were observed in all BMI categories. Higher postoperative infection and 30-d RRs were observed in the morbidly obese. Contrary to previous studies, operating room times were similar regardless of BMI.

Abstract
BACKGROUND AND OBJECTIVE Nodal metastases in the central compartment are frequent in papillary thyroid cancer (PTC). However, they are mostly micrometastases with no impact on survival and their relevance on the risk of locoregional relapse is controversial. There is no consensus regarding optimal management of the central neck in patients with PTC cN0. In our center, we do not perform prophylactic central neck dissection (pCND). The objective of this study is to review our long-term results and compare them with the most recent literature. PATIENTS AND METHODS Retrospective review of patients with PTC who underwent total thyroidectomy (TT) without CND between 2005 and 2017. Primary result was disease-free survival in the neck (DFS). RESULTS 321 patients were identified, mostly T1-T2 tumors (94.1%). Median follow-up was 90 months. DFS in the central compartment was excellent (96.1% at 10 year's follow-up). 19 patients had cervical recurrence, of which 15 underwent salvage surgery. On their last visit, including salvage surgery when appropriate, 77% of patients had excellent response, 18.7% had indeterminate response, 3.1% had biochemically incomplete response and 1.2% had morphologically incomplete response. Recurrent laryngeal nerve (RLN) paralysis after TT was transient in 4.7% of patients and permanent in 0.9% of patients. There were no RLN paralysis after salvage surgery. Permanent hypoparathyroidism occurred in 3.4% of patients. Only one patient had hypoparathyroidism after salvage surgery and it was permanent. CONCLUSIONS Based on long-term results and low rate of complications associated with salvage surgery in our experience, we consider routine pCND is not justified.

Abstract
Objective This study explored prophylactic central compartment lymph node dissection (pCCLND) for patients with cN0 papillary thyroid carcinoma (PTC) and the effect of carbon nanoparticles (CNP) on surgical outcomes. Methods This retrospective study reviewed PTC cases treated at our tertiary medical institution between January 2019 and December 2022. Only patients with indications for total thyroidectomy and cN0 disease were included. CNP has been associated with a higher number of harvested lymph nodes and a lower rate of accidental parathyroid gland (PTG) removal. Patients who used CNP in this study were classified as group 1, while those who denied its use were classified as group 2. Results In total, 116 cases were included, with 80 patients in group 1 and 36 in group 2. Most patients were in stage T1, with 68 (85.0 %) patients in group 1 and 31 (86.1 %) in group 2. Postoperative hoarseness occurred in 3 (3.8 %) patients in group 1 and 1 (2.8 %) in group 2, which recovered within two months. In group 2, 250 nodes were harvested, 72 (28.8 %) of which were metastatic; in group 1, 889 nodes were harvested, 316 (35.5 %) of which were metastatic; the difference regarding the rates of metastatic lymph nodes between the 2 groups was statistically significant (P = 0.047). Differences in postoperative blood calcium and parathyroid hormone levels between the two groups were statistically significant (P = 0.035 and P = 0.034, respectively). There were symptoms of hypocalcemia in 6 (16.7 %) patients in group 2 but in only 2 (2.5 %) in group 1, all of which recovered within three months; the difference was statistically significant (p = 0.017). Conclusion pCCLND is worth undertaking for cN0 PTC. CNP is beneficial for achieving more thorough dissection and reducing temporary hypoparathyroidism.

Abstract
PURPOSE The occurrence and histopathological features of incidental thyroid carcinoma (ITC) vary considerably among populations from different geographical regions. The aim of this study is to assess the prevalence and histopathological characteristics of ITC in patients who underwent thyroid surgery for apparently benign thyroid diseases in an endemic goiter area in Italy. METHODS A total of 649 consecutive patients (531 females and 118 males; mean age, 52.9 ± 11.0 years), who underwent thyroid surgery at the Endocrine Surgery Unit of the tertiary care "Renato Dulbecco" University Hospital (Catanzaro, Italy) in the period between years 2017 and 2022, were included in this retrospective study. A comprehensive histopathological examination was performed on surgically excised thyroid tissue. Logistic regression analysis was employed to identify potential predictors of ITC. RESULTS The histopathological examination revealed the presence of ITC in 81 patients, accounting for 12.5% of the total study population. The female to male ratio was found to be 6.4 to 1. Among the patients with ITC, 72 had papillary carcinoma (PTC), with 53 of these tumors being microcarcinomas (microPTC). Additionally, 5 patients had follicular thyroid carcinoma, 2 patients had low-risk follicular cell-derived thyroid neoplasms, 1 patient had an oncocytic carcinoma, and 1 patient had a medullary thyroid carcinoma. Logistic regression analysis demonstrated a significant association between female sex and incidental microPTC. CONCLUSIONS These findings provide further evidence of the common occurrence of ITC, typically in the form of microPTC, among individuals who undergo thyroid surgery for apparently benign thyroid diseases.

Abstract
INTRODUCTION Thyroid carcinoma is the most common endocrine malignancy, accounting for 3 % of recent malignancies in world wide. Differentiated thyroid carcinoma constitutes 90 % thyroid malignancies, within that follicular type constitutes 10-15 %. CLINICAL PRESENTATION A 55-year-old female presented with left-sided neck pain and swelling over medial end of clavicle, following normal manual work. Physical examination revealed swelling on medial end of left clavicle and palpable nodule in left thyroid lobe. Imaging studies showed two nodules in both thyroid lobes with left level IV lymphadenopathy and osteolytic lesion with pathological fracture in medial end of clavicle. Histopathological evaluation confirmed well-differentiated follicular thyroid carcinoma with clavicular metastasis. The patient underwent total thyroidectomy, followed by radioiodine therapy for medial end of left clavicle. DISCUSSION Follicular thyroid carcinoma (FTC) is metastasis through the bloodstream, predominantly to flat bones and upper end of long bones, but clavicular deposits are very rarely reported. FNAC only diagnosed the follicular neoplasm. Further tissue evaluation needed to confirm the malignancy. Therefore, hemithyroidectomy of the lesion side is usually carried out for histopathological diagnosis. But in this case, follicular thyroid carcinoma was confirmed through core biopsy from medial end of clavicle, leading to total thyroidectomy and left cervical block dissection, followed by radioiodine therapy for metastatic clavicular involvement. CONCLUSION Clavicular metastasis of follicular thyroid carcinoma is very rare. Early detection and proper management of suspicious thyroid carcinoma in uncommon skeletal sites, like the clavicle, is crucial for enhancing patient outcomes, despite the rarity of follicular carcinoma metastasis to this area.

Abstract
Introduction Hypocalcemia is a common complication of total thyroidectomy (TT). This study was designed to investigate the effect of preoperative vitamin.D (Vit.D) status on the occurrence of post-total thyroidectomy hypocalcemia. Materials and Methods Patients who underwent TT without parathyroidectomy were divided into three groups based on their preoperative Serum Vit.D levels (<20 ng/ml, 20-30 ng/ml, and ≥30 ng/ml were considered deficient, insufficient, and normal Vit.D levels, respectively). Serum levels of calcium and phosphorus were measured before and 24 hours after surgery in all patients. The patients were examined for clinical symptoms and signs of hypocalcemia postoperatively. In cases with positive clinical symptoms and signs of hypocalcemia and/or calcium levels <8 mg/dl, PTH level was measured before starting calcium infusion, while serum calcium and phosphorus levels were also measured 24 hours later. Results Among 100 patients enrolled in this study, 81% were females. The mean age was 36.60±8.32 years. Before surgery, the mean Vit.D level was 26.9±16.89 ng/ml, while 47% of cases had normal Vit.D level, 32% had insufficient vitamin levels, and 21% had Vit.D deficiency. Twenty-four hours after surgery, the calcium (P=0.356) and phosphorus (P=0.743) levels were not significantly different between the three Vit.D groups. A comparison of postoperative PTH levels between the three Vit.D groups showed no significant difference (P=0.596). Conclusions Based on our findings, preoperative serum Vit.D levels did not affect postoperative serum calcium levels.

Abstract
The optimal surgical procedure(s) for unilateral multifocal papillary thyroid carcinomas is currently controversial. As such, the present study aimed to compare the efficacies of total thyroidectomy and lobectomy in patients with unilateral multifocal papillary thyroid carcinoma. A literature search of the PubMed/Medline, Embase, Web of Science, Cochrane Library, Wan Fang, and Zhi Wang databases for relevant studies, published from inception to October 31, 2022, was performed. Two researchers independently extracted data from the included studies. Lymph node metastasis, vocal fold paralysis, parathyroid injury, postoperative recurrence, and disease-free survival were evaluated. The meta-analysis included 7 studies comprising 1540 patients, of whom 496 and 1044 underwent lobectomy and total thyroidectomy, respectively. Compared with lobectomy, total thyroidectomy resulted in more vocal cord paralysis (odds ratio [OR] 0.35 [95% confidence interval (CI) 0.13 to 0.96]; P = 0.04) and parathyroid injury (OR 0.11 [95% CI 0.03-0.39]; P = 0.001) but with better disease-free survival (OR 0.21 [95% CI 0.09-0.49]; P = 0.000), although vocal cord paralysis and parathyroid injury, in large part, resolved within 1 year after surgery. In addition, there was no difference in postoperative lymph nodes metastasis (OR 0.74 [95% CI 0.13-4.21]; P = 0.737) and postoperative recurrence (OR 2.37 [95% CI 0.42-13.38]; P = 0.33). Excluding studies that deviated from the general trend, total thyroidectomy was beneficial in reducing recurrence. Compared with lobectomy, total thyroidectomy was beneficial in reducing recurrence and disease-free survival and may be considered a more optimal approach for unilateral multifocal papillary thyroid carcinoma.

Abstract
The focal point of thyroidectomy surgery has always been to reduce the incidence of inadvertent damage to the recurrent laryngeal nerve(RLN). The intracapsular thyroidectomy is one such technique with minimum chance of injuring the nerve. To compare retrospectively the surgical outcomes between the two methods of thyroidectomy-coventional thyroidectomy Vs intracapsular thyroidectomy. Materials and methods-55 cases of benign thyroid disease for whom thyroidectomy was performed in our hospital between the period of 2019-2022 were compared retrospectively. Out of these 34 cases had undergone intracapsular thyroidectomy and 21 cases underwent routine extracapsular thyroidectomy. The surgical outcomes including operation time, pain, postoperative infection, postoperative hypocalcemia, postoperative recurrent laryngeal nerve paralysis and mean hospital stay were analyzed. The mean operating time were very low in the intracapsular limb as compared to the other group. The pain and the mean hospital stay was also far lesser for the intracapsular limb. Both cohorts had no incidence of hypocalcemia. The incidence of recurrent laryngeal nerve palsy was very low in the intracapsular cohort (only 1 case of temporary unilateral RLN palsy), whereas it was higher in the routine extracapsular cohort (5 cases of permanent palsy). The risk of having vocal cord palsy (left/right) is 1.172 times more with conventional/standard thyroidectomy as compared to intracapsular thyroidectomy. Intracapsular technique is a much more rewarding method to perform thyroidectomy, without the risk of the recurrent laryngeal nerve palsy as compared to routine thyroidectomy.

Abstract
BACKGROUND Postoperative hypocalcemia is a common complication of thyroidectomy. This problem is most often associated with accidental devascularization or excision of the parathyroid glands (PG). AIM Aim was to study near-infrared (NIR) fluorescent imaging with intraoperative PG indocyanine green (ICG) angiography to help identify and preserve PG during total thyroidectomy in order to avoid postoperative hypocalcemia. MATERIAL AND METHODS From 2017 to 2022, a total of 92 patients underwent total thyroidectomy at Odessa Regional Hospital. Indications for surgery were multinodular goiter (n = 42), thyroid cancer (n = 43), and Graves' disease (n = 7). By randomization all patients were divided into two groups: in the control group, 48 patients underwent standard total thyroidectomy, and in the main group, 44 patients underwent NIR-assisted total thyroidectomy with ICG angiography. Serum calcium and parathyroid hormone levels were compared between the two groups of patients in 1, 7-15 days after surgery and then 3, 6 months later. RESULTS In the control group, based on a visual assessment of the PG, autotransplantation of the PG was conducted in only five cases. In the second group, autotransplantation was performed in 16 patients. The transient postoperative hypocalcemia was observed in 8 patients of the control group (16, 70%) and in the 2 patients of ICG group (4, 50%) on 5-10 postoperative days. In the first group, 2 patients at 3 months after surgery had permanent hypocalcaemia. CONCLUSION NIR fluorescent imaging with intraoperative PG ICG angiography is a safe and an easily repeatable method. This technique provides improved detecting and assessment of the perfusion of the PG. The need for autotransplantation of the PG can be determined more objectively using ICG imaging than simple visualization.

Abstract
BACKGROUND The most frequent complication of total thyroidectomy remains hypocalcemia due to low postoperative levels of serum intact parathyroid hormone (iPTH). The purpose of this study was to investigate the role of decreased iPTH at the end of surgery in predicting hypocalcemia. In addition, we examined the percentage decrease of iPTH as potential indicator of hypocalcemia. METHODS We retrospectively collected the data of patients who underwent total thyroidectomy for benign and malignant diseases at our institution between 2010 and 2022. The iPTH level was measured before and at the end of surgery, and serum calcium levels on the first postoperative day. Demographic, clinical, and biochemical characteristics of patients with low iPTH were compared with patients with normal iPTH levels using ANOVA for continuous variables and χ2-tests for categorical variables. Multivariable logistic regression analysis evaluated the association of iPTH at the end of surgery and the relative reduction of iPTH with postoperative hypocalcemia. RESULTS The mean age of the 607 patients in this study was 55.6 years, and the female-to-male ratio was 5:1. Goiter was the most common indication for surgery (N = 382, 62.9%), followed by Graves' disease (N = 135, 22.2%). The mean preoperative iPTH was 49.0 pg/ml, while the mean postoperative iPTH was 29.3 pg/ml. A total of 197 patients (32.5%) had an iPTH level below normal, 77 patients (39%), had iPTH levels of 10-15.0 pg/ml and 120 patients (61%) of < 10.0 pg/ml at the end of surgery. Among all patients, 124 (20.4%) developed hypocalcemia on the first postoperative day. The mean percentage of decrease of iPTH was highest among patients with iPTH < 10 pg/ml (76.9%, p < 0.01); this group of patients had also the highest rate of postoperative hypocalcemia on day one (45.0% vs. 26.0% vs 12.2%, p < 0.01). CONCLUSIONS Measurement of iPTH at the end of total thyroidectomy predicts patients who are at risk for postoperative hypocalcemia. The combination of low serum iPTH with a decrease in iPTH level of ≥ 50% may improve prediction of hypocalcemia compared to iPTH levels alone allowing for early calcium substitution in these patients at high risk of developing postoperative hypocalcemia.

Abstract
IMPORTANCE AND IMPORTANCE Thyroid lipomatosis is a rare entity of thyroid gland lesions. The exact etiopathogenesis of this condition is unknown. Most patients presented with compression symptoms. Radiological investigations such as neck ultrasonography (U/S) and computed tomography (CT) are crucial to evaluate and diagnose fat-containing thyroid tumors, while the definitive diagnosis is achieved by the histopathological study. CASE PRESENTATION A 78-year-old female patient, with a background medical history of diabetes mellitus type II and chronic kidney disease, presented to our hospital with a seven-month history of large-sized neck swelling. On physical examination, the neck mass was firm, nodular, hard in consistency, and asymmetrical. The neck swelling was associated with swallowing difficulties and minimal voice changes. Laboratory investigations were unremarkable. Neck U/S showed thyroid goiter. FNA and FNAC were also done. Then, neck CT was performed, and bilateral lobulated fat density was detected. So, a total thyroidectomy was performed, and the resected specimen was sent for histopathology studies. The postoperative period was uneventful. CLINICAL DISCUSSION Diffuse thyroid lipomatosis is an unusual non-neoplastic lesion. The clinical features of thyro-lipomatosis include compression symptoms. Radiological tools and cytology aid in diagnosis demonstration but the specific diagnosis is achieved by histopathology. CONCLUSION Due to the rare etiologic origin and unknown pathogenesis of thyrolipoma, we report the case of a 78-year-old female patient with enlarged neck swelling, found to be thyroid lipomatosis.

BACKGROUND TSH receptor autoantibodies (TRAbs) are pathognomonic for Graves' disease and are thought to also underly the pathogenesis of Graves' ophthalmopathy (GO). A decline in TRAb levels has been documented post-total thyroidectomy (TTx) in GO, however with conflicting correlations with disease outcomes. The aim of the study was to compare the effectiveness of TTx to other treatment modalities of Graves' disease and examine whether the lowering of TRAbs is associated with GO improvements. METHOD We searched electronic databases including Medline, Embase, Scopus, and Web of Science until 31 September 2022 using a broad range of keywords. Patients with GO undergoing TTx with measurements of both TRAbs and progression of the disease using a validated GO scoring system were included. Fourteen studies encompassing data from 1047 patients with GO met our eligibility criteria. The PRISMA guidelines were followed, and five studies had comparable data that were suitable for a meta-analysis. RESULTS The Cochrane Risk of Bias tool for RCTs showed low risk of bias across most domains. The pooled odds ratio showed that more patients significantly had normalized TRAb levels post-TTx as compared to other interventions (OR: 1.36, 95% CI: 1.02-1.81, p = 0.035). But, there was no significant difference in GO improvement post-TTx as compared with other intervention groups. CONCLUSIONS This meta-analysis shows that TRAb levels may decline largely post-TTx, but may not predict added improvements to the progression of GO. Thus, future studies with uniform designs are required to assess the minimal significant GO improvements.

Abstract
PURPOSE Transient hypoparathyroidism is the most common complication after total thyroidectomy, and accidental parathyroidectomy (AP) may be a cause. The aim of this study was to investigate the incidence of AP and its impact on postoperative calcemia. MATERIALS AND METHODS From February 2016 to May 2018, 766 patients undergoing total thyroidectomy were prospectively included. Surgical indications, hormonal status, definitive histology, and postoperative calcium and PTH levels were analyzed. RESULTS 578/(75.45%) were women and 188/(24.55%) men with mean age of 53.4 years. Parathyroid tissue on the thyroid specimen was observed in 40 (5.2%) patients: 30 APs and 10 parathyroid fragments. Among the 30 APs, 12 glands were intrathyroid and 18 (2.3%) in eutopic location. 97 (12.6%) patients were treated for postoperative hypocalcemia: 90 (11.7%) had transient and 5 (0.6%) definitive hypoparathyroidism; 2 were lost in follow-up. 13/30 (43.3%) with AP had transient hypoparathyroidism. A strong correlation was found (p < 0.0001) between AP and postoperative hypocalcemia. 1/30 (3.3%) patient with APs had definitive hypoparathyroidism. Transient and persistent nerve palsies were found in 10 (1.3%) and 3 (0.4%) patients, respectively. DISCUSSION A careful examination of the thyroid gland after resection help to identify an AP that could be autotransplanted. Surgeon and hospital activity volume per years seem to reduce the risk of hypoparathyroidism. CONCLUSION Total thyroidectomy and intrathyroid localization of parathyroid glands are risk factors for the AP. The incidence of AP was 2.3%, and this remains low due to our longstanding experience in thyroid and parathyroid surgery.

Abstract
Introduction Hemodynamic disturbance is a common problem in patients undergoing thyroid surgery. It may be due to episodic increases in thyroid hormones (thyroid storm) or stimulation of the carotid sinus baroreflex. The aim of the present study was to investigate effectiveness of the pre-operative oral Clonidine on reducing these hemodynamic changes during total thyroidectomy surgery. Methods In a prospective, randomized, double-blind study, 80 patients scheduled for elective total thyroidectomy were randomized to receive either 0.2 mg Clonidine (n=40) or a matched placebo (n=40) orally sixty minutes before entering the operating room. Hemodynamic variables, the duration of surgery, estimated amount of blood loss and the dose of administered remifentanil were recorded for further analysis. Results Oral Clonidine was found to be significantly better in maintaining stable hemodynamics compared to the control group. Also, In the Clonidine group, the estimated amount of blood loss (110.4±10 ml vs. 182.2±11.4 mL, P=0.04), duration of the surgery (78.26±55.2 min vs. 105.16±61.75 min, P=0.027) and administered dose of remifentanil (26.67±6.6 μg vs. 216.2±14.8 μg, P=0.01) were also significantly lower than the control group. Conclusion Pre-operative administration of 0.2 mg oral Clonidine in patients undergoing total thyroidectomy results in improved perioperative hemodynamic stability and reduced response to perioperative stress.

Abstract
BACKGROUND The published rate of incidental parathyroidectomy (IP) during thyroid surgery varies between 5.8% and 29%. The risk factors and clinical significance of postoperative transient hypocalcemia and permanent hypoparathyroidism are still debated. The aims of this study were to assess the clinical relevance of avoidable IP for transient hypocalcemia and permanent hypoparathyroidism, and to describe the risk factors for IP. METHODS This retrospective cohort study included 1,537 patients who had a one-step total thyroidectomy in a high-volume endocrine surgery center between 2018 and 2019. Pathology reports were reviewed for incidentally removed parathyroid glands. Intrathyroidal parathyroid glands were excluded from the study. Demographic characteristics, potential risk factors, and postoperative calcium and PTH levels were compared between IP and control groups. RESULTS Avoidable IP occurred in 234 (15.2%) patients. Patients with IP had a higher risk of transient hypocalcemia (17.9% vs. 11.5%, p = 0.006; odds ratio [OR] 1.68, 95% confidence interval [95% CI]1.16-2.45) and permanent hypoparathyroidism (4.7% vs. 1.6%, p = 0.002; OR 3.01, 95% CI 1.29-6.63) than patients without IP. Multivariate analysis showed that central lymph node dissection (CLND) and incidental removal of thymus tissue were independent risk factors for IP (OR 4.83, 95% CI 2.71-8.86, p < 0.001 and OR 1.72, 95% CI 1.02-2.82, p = 0.038). CONCLUSIONS Patients with IP were more likely to develop transient hypocalcemia and permanent hypoparathyroidism, indicating the clinical significance of avoidable IP for patients and the need for raising awareness among surgeons. Patients undergoing CLND are at a higher risk for IP, and should be adequately informed and treated. Any removal of thymus tissue should be avoided during CLND.

Abstract
Purpose Postoperative hypoparathyroidism is the most frequent complication after total thyroidectomy. The identification of preoperative predictors could be helpful to identify patients at risk. The aim of this study is to determine if preoperative vitamin D levels are related to transient, protracted, and permanent hypoparathyroidism. Method A prospective, observational study that includes 100 patients who underwent total thyroidectomy. Results Transient hypoparathyroidism was present in 42% of patients, 11% developed protracted hypoparathyroidism and 5% permanent hypoparathyroidism. The median preoperative Vitamin D levels were higher in patients who developed transient hypoparathyroidism than in patients without this complication (24 ng/mL [RIQ 13-31] vs. 17 ng/mL [RIQ 10-24]; p = 0.024). Patients with preoperative vitamin D levels below 20 ng/mL had a lower percentage of transient hypoparathyroidism (31.4% vs. 53.1%; p = 0.028). The prevalence of protracted and permanent hypoparathyroidism in both groups was similar. Patients with preoperative vitamin D levels lower than 20 pg/mL had higher median PTH levels 24 h after surgery, (37.7 ± 28.2 pg/ml vs. 23.6 ± 18.6 pg/ml; p = 0.037), and suffered a lower postoperative PTH decline (46.2 ± 35.4% vs. 61 ± 29%; p = 0.026). Conclusions Patients with vitamin D deficiency had a lower transient hypoparathyroidism rate, higher median PTH levels 24 h after surgery and a lower postoperative PTH decline. We found no association between preoperative vitamin D and the development of protracted or permanent hypoparathyroidism.

Abstract
BACKGROUND Post-operative Hypocalcaemia is the most-common complication of total and near-total thyroidectomy which is a selective treatment for benign and malignant thyroid diseases. Incidence ranges from 0.5-50%. OBJECTIVES The role of vitamin-D and Parathyroid hormone(PTH) in incidence of Hypocalcemia after thyroidectomy has been taken into consideration. METHODS This is a prospective interventional study is conducted in Kasturba Medical College and hospital, Manipal after taking written informed consent from the participants. It aimed at surveying the serum level of preoperative Vitamin D, PTH and calcium before total-thyroidectomy surgery and its relationship with the incidence of postoperative hypocalcemia after the surgery. The study was done on 70 patients who were-planned for total/near total thyroidectomy. Preoperative Vitamin D, PTH, calcium and Postoperative 4 hours-PTH, Calcium were measured on POD-1, POD-2-4, the results obtained were then analysed. RESULTS Considering the cut-off of calcium as 8.6mg/dl, 42 patients developed hypocalcemia on POD-1, 28 patients on POD-2. Preoperative calcium and postoperative PTH levels in people having hypocalcaemia where significantly less compared to the patients having normal calcium. 4-hours post-operative PTH measurements showed 51% sensitivity, 100% specificity and strong co-relation between postoperative hypocalcemia and drop in PTH levels- (p=<0.001). Out of 42 patients who developed hypocalcemia 28- (65%) patients had vitamin-D deficiency(p=0.5) on POD-1 and out of 51 patients with hypocalcemia on POD 2-4, 33(78%) had-vitamin-D-deficiency(p=0.3852). Which was not statically significant. CONCLUSION 4 hours post-operative PTH level is a predictor of early postoperative hypocalcemia, by detecting this we can effectively manage postoperative hypocalcemia.

Abstract
Hypocalcemia is one of the most common complication after bilateral thyroid surgery. Reported rates range from 5 to 35% and 0.5 to 4.4% for transient and permanent hypocalcemia respectively. Various methods have been devised to reduce the post-operative hypocalcemia and range from modification of surgical techniques to use of loops and avoidance of inadverant neck dissections. We conducted a randomised control trial of 50 patients divided into two groups, to evaluate the effect of microdissection and ligation of distal branches of inferior thyroid artery (group B) on incidence of temporary and permanent hypocalcaemia in patients of total thyroidectomy versus its ligation distally close to the thyroid capsule(group A). Postoperative mean total serum calcium levels were lower in group A as compared to group B (9.13 mg/dl vs. 9.33 mg/dl at 24 h; 8.77 vs. 9.10 at 3rd day and 8.58 vs. 8.96 mg/dl on 10 th day) with p > 0.05. The value of ionized serum calcium as recorded on 3rd day was 4.39 mg/dl for group A and 4.72 mg/dl for group B with p value ≤ 0.001 (Table 2). 19 patients in group A required calcium supplementation for 6 months with incidence of transient hypocalcemia at 76% while 11 patients in group B had calcium supplementation for 6 months with incidence of 40% and difference was significant statistically. Microdissection technique is better for preventing the temporary hypocalcemia and hence decreasing the hospital visits of the patient when compared to the ligation of inferior thyroid artery distally close to the thyroid gland. The incidence of permanent hypocalcemia doesn't varies significantly between both techniques.

Abstract
Objectives Total Thyroidectomy (TT) in true sense is not total as evidenced by remnant uptake in radio-iodine scans and serum thyroglobulin. The aim of this study is to assess the completeness of TT, operating time and recurrent laryngeal nerve injury with and without neuro-monitoring (IONM). Methods Cross sectional analytical study using retrospective data of patients undergoing total thyroidectomy for benign and malignant goiters. Surgeries performed by single surgeon. Patients undergoing TT (2015-22) were grouped into Group A (n = 400) and Group B (n = 400) based on use of IONM. Subgroup of patients (Group A1&B1) who had differentiated thyroid cancer were compared for completeness of thyroidectomy with DxWBS and serum thyroglobulin (TG). Group A and B were compared for operating time and incidence of RLN palsy. Results Of the 800 RLN at risk transient RLN palsy was lower with IONM (p = 0.048). Mean operating time was significantly higher in Group-B(p = 0.0038). Subgroup A1 showed lower radio-active iodine uptake percentage, higher number of patients with negative scan, TG of < 1ng/mL indicating better completeness of TT. Conclusion Our study shows better completeness of thyroidectomy, lower incidence of transient RLN palsy and shorter operating time with IONM.

Abstract
BACKGROUND We have performed an updated meta-analysis of randomized controlled trials (RCT) comparing total thyroidectomy (TT) with less than total thyroidectomy (LTT) for benign multinodular non-toxic goiter (BMNG). OBJECTIVES The objective was to evaluate the effects and outcomes of TT as compared to LTT. METHODS Eligibility criteria: RCTs comparing TT vs LTT. INFORMATION SOURCES PubMed, Embase, Cochrane Library and online registers were searched for articles comparing TT with LTT. Risk of bias: Articles were assessed for risk of bias using the Cochrane's revised tool to assess risk of bias in randomized trials (RoB 2 tool). SYNTHESIS OF RESULTS The main summary measures were risk difference using a random effects model. RESULTS Five randomized controlled trials were included in the meta-analysis. Recurrence rate was lower for TT compared to LTT. Adverse events like temporary or permanent recurrent laryngeal nerve (RLN) palsy and permanent hypoparathyroidism were similar in both groups except for the rate of temporary hypoparathyroidism which was lower in the LTT group. DISCUSSION All studies had unclear risk of bias for blinding of the participants and personnel and high risk of bias for certain selective reporting. This meta-analysis did not show any clear benefit or harm of either procedure (TT vs LTT) for goiter recurrence and re-operation rates (for both recurrence and incidental thyroid cancer). However, re-operation for goiter recurrence was significantly higher in the LTT group based on a single RCT. Evidence suggests increased rates of temporary hypoparathyroidism with TT but there was no difference in the rate of RLN palsy and permanent hypoparathyroidism between the two methods. The overall quality of evidence was low to moderate.

Abstract
INTRODUCTION There has not been a universal agreement about the timings and the threshold level of PTH that can accurately predict the risk of hypocalcemia. Our study aimed to investigate the changes in the serum PTH levels at various time intervals and correlate it with the development of subsequent hypocalcemia. MATERIALS AND METHODS All patients had a pre-operative serum PTH done and were again assessed intra-operatively, at 4 h, 24 h, 72 h, and 1 month after the thyroid surgery. Absolute serum PTH value at various time points, absolute change in serum PTH values compared to pre-operative level, and relative change (percentage change) in serum PTH values compared with pre-operative levels were used to predict post-operative Hypocalcemia. RESULTS 49 patients were included in the study. The sensitivity and negative predictive value was 100% for serum PTH at 4 h. There was a statistically significant difference between the groups that required calcium supplementation versus the group that did not require it. The maximum relative reduction in serum PTH value with respect to the pre-operative level occurred at 4 h in the calcium supplement required group which was 82.5%. Use of combination of 4 h serum PTH and relative change at 4 h yielded the best results. CONCLUSION A combination of absolute serum PTH level at 4 h and the relative decline in serum PTH at 4 h has the highest diagnostic accuracy. The use of this combined parameter helps to reliably predict patients who would require supplementation.

Abstract
These recommendations, drawn from current data in the medical literature, incorporate the risks of hemithyroidectomy (HT) and total thyroidectomy (TT) and clarify the place of these two procedures in clinical settings. Discussions leading to a consensus were then assessed by the Francophone Association for Endocrine Surgery (Association francophone de chirurgie endocrinienne [AFCE]), along with the French Society of Endocrinology (Société française d'endocrinologie [SFE]), and the French Society of Nuclear Medicine (Société française de médecine nucléaire [SFMN]). The complication rate was twice as high after TT compared to HT. Total thyroidectomy requires life-long thyroid hormone supplementation, whereas such supplementation is required in only 30% of patients after HT. When surgery is indicated for Bethesda category II nodules, and in the absence of any indication for surgery on the contralateral lobe, HT is recommended. In patients with thyroid cancer (TC)≤1cm requiring surgical management or TC≤2cm, in the absence of risk factors for TC and in the absence of pre- or intraoperative detection of extrathyroidal extension, lymph node metastases (cN0) and/or suspected contra-lateral disease, HT is the preferred technique as long as the patient accepts the possibility of TT which might be required when aggressive forms of cancer are detected on definitive cytohistology (extrathyroidal extension, lymphovascular invasion, high-grade histology). For TC measuring between 2 and 4cm, the debate between HT and TT remains open today, although some surgeons tend to prefer TT. In patients with TC>4cm, macroscopic lymph node involvement (cN1), signs of extrathyroidal extension or predisposing factors for TC, TT is the treatment of choice.

Abstract
BACKGROUND The thyroid gland plays an important endocrine function regulating metabolism, growth and development. A variety of benign and malignant conditions necessitate surgical removal of the thyroid gland, either in its entirety, or partially. Thyroidectomy is the most commonly undertaken endocrine surgery. Hypocalcaemia, occurring at a rate of approximately 25%, is the most common complication following total thyroidectomy. Hypocalcaemia can increase healthcare costs requiring further investigations, treatment and delaying discharge. Severe hypocalcaemia can be potentially life threatening. It has been demonstrated that routine post-operative supplementation with Vitamin D and calcium, can reduce post-operative hypocalcaemia, at present it is unclear whether preoperative supplementation has a similar effect. METHODS This systematic review includes randomised controlled trials on human adult subjects, who received preoperative Vitamin D and/or calcium, and which studied the effect on post-operative hypocalcaemia following total or near total thyroidectomy. There were no restrictions in respect of post-operative supplementation regimen. Studies were limited to those published in English. RESULT Seven of the eleven trials demonstrated a reduction in either laboratory or clinical hypocalcaemia with preoperative supplementation. This benefit was most likely to be seen when postoperative supplementation was performed on an as needed basis. IV calcium was required to treat resistant or severe hypocalcaemia, in five of the eleven trials, in each of these five trials, rates of IV replacement were lower in the preoperative supplementation group. CONCLUSION The use of preoperative Vitamin D, with or without calcium, may provide a modest reduction in the incidence of laboratory and clinic hypocalcaemia following total or near total thyroidectomy. There is a trend toward a reduced requirement for IV calcium with preoperative supplementation. Larger robust randomised trials are needed to provide a definitive answer. Preoperative supplementation can be considered in patients undergoing total or near total thyroidectomy.

Abstract
INTRODUCTION This study aims to analyze the relative risks for total thyroidectomies by comparing complication rates for total versus partial thyroidectomy in the pediatric population. METHODS We queried the Kids' Inpatient Database (KID) 1997-2012 for all cases of total (n = 3253) or partial (n = 2380) thyroidectomy. We then designed a propensity score matching model and compared total versus partial thyroidectomy based on surgical complications and outcomes. RESULTS In our cohort, the median age was 16 years and 79% were females. Those treated at a specialty pediatric hospital or pediatric unit in a general hospital comprised 73% of all patients. The most common indications for surgery were malignancy (46%) and goiter (42%). The most common complications were hypocalcemia and nerve injury with an unweighted incidence of 9% (n = 174) and 3% (n = 57) respectively. When compared to partial thyroidectomy, total thyroidectomy was associated with increased rates of postoperative complications. Additionally, the median length of stay was significantly higher for total thyroidectomy patients. CONCLUSIONS This is the largest analysis to date comparing outcomes for total versus partial thyroidectomy in the pediatric population. Surgeons should consider the increased rates of hypocalcemia and nerve injury complications when selecting total compared to partial thyroidectomy in children.

Abstract
INTRODUCTION Total thyroidectomy for benign disease is becoming more common among children. The purpose of this study was to evaluate 30-day outcomes in children undergoing total thyroidectomy and determine if the short-term outcomes are different in those with a malignant versus benign indication for surgery. METHODS This retrospective cohort study used the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (NSQIP-Pediatric) to identify all children who underwent total thyroidectomy from 2015 to 2019. Fisher's exact test was used to compare postoperative outcomes between benign and malignant indications for thyroidectomy. RESULTS Among 1595 total thyroidectomy patients, 1091 (68.4%) had a benign indication and 504 (31.6%) had a malignant indication. There were 1234 (77.4%) females, and the median age was 14.9 y (interquartile range [IQR] 12.5, 16.6). Average length of stay (LOS) was similar between cohorts (1.7 d for benign and 1.9 d for malignant, P = 0.30). Parathyroid auto-transplantation was performed in 71 (6.5%) patients in the benign cohort and 43 (8.6%) in the malignant cohort (P = 0.15). The most common complications were readmissions (23 [2.1%] benign and 15 [3.0%] malignant, P = 0.29) and reoperations (7 [0.6%] benign and 5 [1.0%] malignant, P = 0.54). Complication profiles were similar between benign and malignant cohorts (2.8% and 4.6%, respectively [P = 0.10]). CONCLUSIONS Children undergoing total thyroidectomy for benign and malignant indications have low rates of 30-d postoperative complications, suggesting that total thyroidectomy is a safe option for children with benign disease. Evaluation of long-term outcomes is needed.

Abstract
We have recently witnessed a rapid increase in the incidence of differentiated thyroid carcinoma (DTC), particularly low and very low-risk papillary thyroid carcinoma. Simultaneously, the number of cancer-related deaths has remained stable for more than 30 years. Such an indolent nature and long-term survival prompted researchers and experts to an ongoing discussion on the adequacy of DTC management to avoid, on the one hand, the overtreatment of low-risk cases and, on the other hand, the undertreatment of highly aggressive ones.The most recent guidelines of the American Thyroid Association (ATA GL) moved primary thyroid surgery in DTC towards a less aggressive approach by making lobectomy an option for patients with intrathyroidal low-risk DTC tumors up to 4 cm in diameter without evidence of extrathyroidal extension or lymph node metastases. It was one of the key changes in DTC management proposed by the ATA in 2015.Following the introduction of the 2015 ATA GL, the role of thyroid lobectomy in DTC management has slowly become increasingly important. The data coming from analyses of the large databases and retrospective studies prove that a less extensive surgical approach, even if in some reports it was related to a slight increase of the risk of recurrence, did not show a negative impact on disease-specific and overall survival in T1T2N0M0 low-risk DTC. There is no doubt that making thyroid lobectomy an option for low-risk papillary and follicular carcinomas was an essential step toward the de-escalation of treatment in thyroid carcinoma.This review summarizes the current recommendations and evidence-based data supporting the necessity of de-escalation of primary thyroid surgery in low-risk DTC. It also discusses the controversies raised by introducing new ATA guidelines and tries to resolve some open questions.

Abstract
INTRODUCTION This study aimed to identify patients at risk of long-term hypocalcaemia following total thyroidectomy for Graves' disease, and to determine the thresholds of postoperative day 1 serum calcium and parathyroid hormone (PTH) at which long-term activated vitamin D treatment can be safely excluded. METHODS This study was a retrospective analysis of 115 consecutive patients undergoing total thyroidectomy for Graves' disease at a university referral centre between 2010 and 2018. Outcome measures were the day 1 postoperative adjusted calcium and PTH results, and vitamin D analogue need at 6 months postoperatively. Logistic receiver operating curves were used to identify optimal cut-off values for adjusted serum calcium and serum PTH, and sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. RESULTS Temporary hypocalcaemia was observed in 20.9% of patients (mean day 1 serum adjusted calcium 2.2±0.14mmol/l and PTH 4.15±2.42pmol/l). Long-term (>6 months) activated vitamin D analogue therapy was required in five patients (4.3%), four of whom had normal serum PTH and one with undetectable PTH at 6 weeks post surgery. No patient with a day 1 postoperative calcium >2.05mmol/l and detectable PTH required vitamin D supplementation at 6 months post surgery (100% sensitivity, PPV 50%, NPV 100%). CONCLUSIONS The biochemical postoperative day 1 thresholds identified in this paper have a 100% NPV in the identification of patients who are likely to require either no or only temporary activated vitamin D supplementation. We were able to identify all patients requiring activated vitamin D supplementation 6 months postoperatively from the day 1 postoperative serum calcium and PTH values, while excluding those that may only need temporary calcium supplementation. These threshold levels could be used for targeted follow-up and management of this subset of patients most at risk of long-term hypocalcaemia.

Abstract
Thyroid hormone replacement therapy is used to raise undesirably low concentrations of natural thyroid hormones, commonly by administrating levothyroxine (LT4). Finding the appropriate LT4 dose regime, particularly for patients undergone thyroidectomy, is still demanding more effort, and much research has been conducted. Providing a new fuzzy logic system, a useful control algorithm, we aim to introduce a proper LT4 dosing regimen for every thyroidectomized patient in a computerized environment. Consequently, we contrast the differences between our proposed dose regime and conventional monotherapy methods using THYROSIM, a thyroid simulation application. Considering our nine defined comparative criteria, results reveal that the FLS dose regime is dominant in terms of six indexes, while the discrepancies are not noticeable in the other three indexes. A great superiority of FLS dose regime is its ability to reduce the time to reach desirable thyrotropin (Thyroid Stimulating Hormone, TSH) serum concentration to 6 days post-thyroidectomy, and keep the T4, T3, and TSH values in the normal window afterward. The proposed FLS could be an applicable decision support system for physicians as they can define their intended Individual Target Value of TSH for each patient to optimize LT4 dose adjustment.

Abstract
INTRODUCTION Total thyroidectomy (TT) has been shown to be a safe and effective treatment for Graves' disease. However, the time course for improvement of symptoms has not been defined. METHODS With an institutional review board approval, we prospectively gathered survey data of all patients (n = 79) undergoing TT for Graves' disease at a single institution from 2019 to 2021. After informed consent was obtained, patients completed surveys preoperatively and at 2 wk followed by monthly postoperative visits/phone calls. Patient demographics and survey results were collected and analyzed. Symptom recovery time was evaluated using Kaplan-Meier analysis. RESULTS A total of 50 patients completed the survey on postoperative follow-up (response rate 63%). Average age was 38 y (range 12-80 y) and 88% of patients were female. The most common preoperative symptoms were fatigue (90%) and heat/cold intolerance (88%). Tremor (median time to resolution: 1 wk; interquartile range [IQR] 1-3), diarrhea (median 1 wk [IQR 1-3]), and palpitations (median 1 wk [IQR 1-3]) resolved the most rapidly followed by eye symptoms (median 3 wk [IQR 1-6]), heat/cold intolerance (median 3 wk [IQR 3-30]), memory deficits (median 3 wk [IQR 1-undefined]), and fatigue (median: 3 wk [IQR 1-14]). There were no significant differences in time to resolution of symptoms by gender or age (less than versus 40 y and older). Those with uncontrolled Graves' had more severe symptoms but no difference in time to resolution from the euthyroid Graves' patients. CONCLUSIONS Many Graves' disease symptoms improve rapidly following TT, with a median time to improvement of less than 1 mo.

Abstract
PURPOSE Pediatric total thyroidectomy is an uncommon procedure. Higher rates of complication are reported for pediatric patients compared to adults which may be secondary to lower case volume. In this study, we examine the effect of a two-surgeon operative approach on outcomes in pediatric total thyroidectomy. METHODS A retrospective review of 152 pediatric patients undergoing total thyroidectomy at a single institution was performed. A control group of 89 patients, with one attending surgeon present, was compared to a cohort of 63 pediatric patients who underwent total thyroidectomy with two attendings present. Primary outcomes included rates of permanent hypoparathyroidism and recurrent laryngeal nerve (RLN) injury. The secondary outcomes included postoperative hematoma, length of stay (LOS), LOS greater than 1 day (>1d) secondary to hypocalcemia, and readmissions secondary to hypocalcemia. RESULTS One RLN injury was documented in each cohort and no postoperative hematomas were documented. Rates of permanent hypoparathyroidism decreased in the two-surgeon cohort (11.48%) when compared to the control group (15.73%) but was not significant. There was a statistically significant decrease in LOS >1d secondary to hypocalcemia in the two-surgeon cohort. LOS >1d attributable to hypocalcemia was seen in 38.2% in the control group versus 15.87% in the 2-surgeon cohort (p = 0.003). CONCLUSIONS Implementation of a two-surgeon operative approach was shown to lead to a significant decrease in length of stay >1d attributable to hypocalcemia. However, this change was in the setting of multidisciplinary thyroid team and postoperative protocol implementation, and concentration of surgeons performing the operation. Further studies are needed to investigate the effects of the two-surgeon operative approach further.

Abstract
INTRODUCTION Thyroid hormones play an important role in body weight regulation. In this study, we investigated which body composition parameters cause a change in body weight after total thyroidectomy. MATERIALS AND METHOD We performed a retrospective cohort study of a prospectively maintained database of patients who underwent total thyroidectomy. Demographics, thyroid function tests, indications for surgery, final pathology, and postoperative thyroid status were collected. Body composition analyses measured by the bioelectrical impedance analysis method were recorded at two-time points, 12 months apart. RESULTS Forty-four patients were included in the study with a mean age of 51.6 years. There were statistically significant increases in weight (p=0.049), body mass index (p=0.021), and fat mass (p=0.001) over time. While 12 patients (27.3%) lost or maintained weight, 32 patients (72.7%) gained weight. There was no significant difference in age, sex, preoperative thyroid function tests, postoperative thyroid status, or pathology between those who gained weight and those who did not. Although changes in all body composition parameters were higher in males than in females, these differences were not significant overall. Multivariable regression analysis revealed a significant positive relationship between increase in fat mass and baseline free-T3 (p=0.041) and found that lower baseline percent body fat was a significant factor for greater fat mass gain (p=0.016). However, no predictors of change in weight were identified. CONCLUSION We conclude that total thyroidectomy results in a significant change in body weight and fat mass. Higher free-T3 and lower percent body fat at baseline were significant factors of fat mass gain.

Abstract
BACKGROUND To evaluate the association of preoperative vitamin D levels with postoperative hypocalcaemia after total thyroidectomy. METHODS The medical records of patients who underwent total thyroidectomy between May 2020 and January 2022 and who had a documented preoperative serum 25-hydroxyvitamin D (25-OHD) concentration were retrospectively reviewed. Vitamin D levels were categorized into four groups: <10 ng/mL (severe vitamin D deficiency), 10-20 ng/mL (vitamin D deficiency), 20-30 ng/mL (vitamin D insufficiency), and > 30 ng/mL (vitamin D sufficiency). Multivariate logistic regression was performed to analyse the association of vitamin D levels with the risk of hypocalcaemia after controlling for potential confounding factors. RESULTS A total of 196 patients were included in this study. Of these, 47 (24.0%) had preoperative 25-OHD < 10 ng/mL, 62 (31.6%) had 25-OHD of 10-20 ng/mL, 51 (26.0%) had 25-OHD of 20-30 ng/mL and the remaining 36 (18.4%) had 25-OHD > 30 ng/mL. The incidence of postoperative hypocalcemia was highest in the group of patients with severe vitamin D deficiency (42.6% and 23.4% for postoperative laboratory and symptomatic hypocalcaemia, respectively), followed by the group with vitamin D deficiency (29.0% and 16.1%), the group with vitamin D insufficiency (19.6% and 5.9%) and the group with vitamin D sufficiency (5.6% and 2.8%). Multivariate logistic regression indicated that the odds of postoperative laboratory hypocalcaemia for patients with severe vitamin D deficiency and vitamin D deficiency were 13.20 times (95% CI: 2.69-64.79, P < 0.01) and 6.32 times (95% CI: 1.32-30.28, P = 0.02) greater than for those with vitamin D sufficiency, respectively; while the odds of symptomatic hypocalcaemia for patients with severe vitamin D deficiency was 10.18 times (95% CI: 1.14-90.86, P = 0.04) greater than for those with vitamin D sufficiency. CONCLUSION Preoperative vitamin D deficiency (< 20 ng/mL), especially severe vitamin D deficiency (< 10 ng/mL), is an independent predictive factor of postoperative hypocalcaemia after total thyroidectomy.

Abstract
Objectives Papillary thyroid cancer (PTC) is the most common type of thyroid cancers. In some patients, due to the histopathological features of PTC, complementary thyroidectomy (CT) may be needed to contralateral thyroid lobe after lobectomy. Hypocalcemia is the most common complication after thyroidectomy and its etiology is multifactorial. It is still controversial whether the CT increases the risk of hypocalcemia or not. In this study, we aimed to evaluate whether CT procedure increases the risk of hypocalcemia compared to total thyroidectomy (TT) in PTC patients. Methods The data of the patients who were operated between 2015 and 2018 and diagnosed with PTC in the pre-operative or post-operative period were evaluated retrospectively, and two patient groups were formed. Group 1 included 19 patients who were diagnosed with PTC in the pathological examination after lobectomy was performed in the first operation, and after that CT was performed to the contralateral lobe. Among the patients who were diagnosed with pre-operative or post-operative PTC in the same period, 53 patients with characteristics similar to the 1st group in terms of age and gender were selected for Group 2. Biochemical parameters related to calcium metabolism in the pre-operative and post-operative periods, parathyroid autotransplantation and unintentional parathyroid gland removal, post-operative hypocalcemia, and treatment rates were compared between the two groups. Results There were 19 patients (13 F and 6 M) with a mean age of 48.3±12.1 years and 53 patients with a mean age of 46.3±9 (40 F and 13 M) in Groups 1 and 2, respectively, and there was no significant difference between the groups in terms of age and gender. There was no significant difference in terms of pre-operative parathormone (PTH), phosphorus (P), magnesium (Mg), Vitamin D deficiency rate, parathyroid autotransplantation, and presence of parathyroid gland in thyroid specimen. Pre-operative calcium (Ca) value was 9.33±0.46 in Group 1 and lower than Group 2 (9.65±0.41) (p=0.012). There was no significant difference between the groups in terms of post-operative day 0 Ca, P, Mg, and PTH and post-operative day 1 Ca, Mg, and PTH. Post-operative day 1 P level was significantly lower in Group 1 (2.86±0.72) compared to Group 2 (3.6±0.83). Post-operative hypocalcemia rates were 21.1% and 30.2% in Groups 1 and 2, respectively, and the difference was not significant (p=0.558). In both groups, hypocalcemia was transient and permanent hypoparathyroidism was not detected. Parathyroid autotransplantation rates (10.5% vs. 3.8%; p=0.283) and the rate of unintentionally removed parathyroid gland (0 vs. 15.1; p=0.185) were similar in Groups 1 and 2, respectively. Ca and active Vitamin D administration rates in the post-operative period were similar in Group 1 and Group 2 (10.5% vs. 22.6%; respectively), and there was no significant difference between the groups in terms of receiving treatment (p=0.327). Conclusion CT can be necessary in some patients with post-operative diagnose of PTC. CT can be performed without increased risk of hypocalcemia compared to TT.

Abstract
The SFE-AFCE-SFMN 2022 consensus deals with the management of thyroid nodules, a condition that is a frequent reason for consultation in endocrinology. In more than 90% of cases, patients are euthyroid, with benign non-progressive nodules that do not warrant specific treatment. The clinician's objective is to detect malignant thyroid nodules at risk of recurrence and death, toxic nodules responsible for hyperthyroidism or compressive nodules warranting treatment. The diagnosis and treatment of thyroid nodules requires close collaboration between endocrinologists, nuclear medicine physicians and surgeons, but also involves other specialists. Therefore, this consensus statement was established jointly by 3 societies: the French Society of Endocrinology (SFE), French-speaking Association of Endocrine Surgery (AFCE) and French Society of Nuclear Medicine (SFMN); the various working groups included experts from other specialties (pathologists, radiologists, pediatricians, biologists, etc.). This section deals with the surgical management of thyroid nodules.

Abstract
Backgroud Postoperative nausea and vomiting (PONV) is one of the most common complications after total thyroidectomy under general anesthesia. Total intravenous anesthesia (TIVA) has been documented to prevent PONV in patients undergoing total thyroidectomy. Penehyclidine, an anticholinergic agent with an elimination half-life of over 10 h, is widely used as premedication to reduce glandular secretion. This study aimed to explore the preventative effects of penehyclidine with propofol-remifentanil-TIVA to single-TIVA on PONV in patients undergoing total thyroidectomy. Methods A total of 100 patients scheduled for total thyroidectomy were randomly assigned to either the penehyclidine group (n = 50) or TIVA group (n = 50). Propofol and remifentanil were was used for TIVA in all patients. No patients who received premedication. Patients were administrated with either 5 ml of normal saline or 0.5 mg of penehyclidine soon after anesthesia induction. The incidence of nausea and vomiting, the severity of nausea, the requirement of rescue antiemetics, and adverse effects were investigated during the first 24 h in two time periods (0–2 h and 2–24 h). Results The overall PONV incidence during the 24 h after surgery was significantly lower in the penehyclidine group compared with the TIVA group (12% vs 36%, P < 0.005). Besides, the incidence of nausea and the incidence of vomiting were significantly lower in the penehyclidine group compared with the TIVA group at 2–24 h after surgery. However, there was no significant difference between the two groups at 0–2 h after surgery. Conclusions Administration of penehyclidine under TIVA with propofol-remifentanil is more effective for prevention of PONV than TIVA alone, especially 2–24 h after total thyroidectomy.

Abstract
PURPOSE Persistent hypoparathyroidism (hypoPT) is a major complication of total thyroidectomy. Nonetheless, previous reports may have underestimated the prevalence of hypoPT due to patient selection bias. We aimed to estimate the actual prevalence of persistent hypoPT after total thyroidectomy and to find predictive factors for postoperative hypoPT. METHODS This study retrospectively reviewed data from a health insurance claims-based database provided by the Japan Medical Data Center Co., Ltd. From 2009 to 2019, 2388 patients who underwent total thyroidectomy were identified using the medical procedure codes. Persistent hypoPT was defined as the prescription of active vitamin D supplements for >1 year postoperatively and the assignment of hypoPT codes. The prevalence of persistent hypoPT was estimated at two different levels: minimum and maximum estimations with or without postoperative osteoporosis and/or renal failure codes. Correlates for persistent hypoPT were investigated among several demographic and clinical variables. RESULTS Of the 2388 patients, 1752 (73.4%) were women with a mean age of 45 years. The types of diseases were: benign thyroid disease (n = 235), malignant thyroid tumors (n = 1570), Graves ' disease (n = 558), and malignancy combined with Graves' disease (n = 25). The minimum and the maximum estimation of the prevalence of persistent hypoPT were 15.0 and 20.3%, respectively. Multivariate logistic regression analysis showed that the malignant tumor (odds ratio, 1.8) independently correlated with persistent hypoPT. CONCLUSIONS The prevalence of persistent hypoPT after total thyroidectomy estimated by the claims-based database was higher than previously recognized. Comprehensive attempts to preserve parathyroid function, especially in malignant diseases, are essential.

Abstract
Preserving all parathyroids with intact blood supply in situ is a desirable goal while performing total thyroidectomy (TT) and central compartment dissection (CCLND), but the same is not feasible in presence of bulky and/or matted lymph nodes in the central compartment. The aim of this study was to investigate the difference in incidence of postoperative hypocalcemia between the groups of papillary thyroid carcinoma (PTC) patients who had truncal ligation (TL) versus ligation of peripheral branches (PL) of inferior thyroid artery (ITA) during TT and CCLND. Retrospective review of prospectively kept data of PTC patients undergoing TT and CCLND. Patients were divided in two groups: Group 1-(n = 57) patients who had to undergo TL and Group 2-(n = 99) patients having PL. Clinico-pathologic profile, operative details and follow-up events were noted. Clinico-pathologic profile of both groups was comparable except for higher incidences of tumor multicentricity (p = 0.014) in Group 1. There was no significant difference in the number of parathyroids identified between the Groups (p = 0.556) but more parathyroids were auto-transplanted in Group 1 (p = 0.001). The incidence of temporary (77.2% vs 83.8, p = 0.304) and permanent hypocalcemia (7% vs 8.1%, p = 0.810) was not significantly different between the groups and neither was need for intravenous calcium. At discharge, Group 1 patients received lower dose of calcium (p = 0.001) but not of vitamin D (p = 0.769). TL of ITA during CCLND does not result in increased temporary or permanent hypocalcemia rate.

Abstract
The incidence of thyroid cancer is increasing, whereas mortality remains relatively stable. An increasing body of research supports the use of less-intensive treatment for low-risk thyroid cancer, as the overall prognosis is excellent. Although total thyroidectomy was the gold standard for many years, the options of lobectomy alone, active surveillance, and other ablative modalities are increasingly being used. The clinicohistologic features of any thyroid cancer are important to help determine the optimal management for a given tumor. However, the patient's own desires and goals in their cancer treatment must be evaluated.

Abstract
INTRODUCTION With increasing rates of obesity worldwide, a correlation between high body mass index (BMI) and postoperative morbidity after thyroid surgery remains unclear. Postoperative transient hypocalcemia is common after total thyroidectomy due to interruption of parathyroid function. This study examines the relationship between BMI and hypocalcemia after total thyroidectomy. MATERIALS AND METHODS A retrospective review of prospectively collected data for 1135 patients who underwent total thyroidectomy for cancer, multinodular goiter (MNG), or Graves' disease between June 2009 and November 2020 at a single institution was performed. BMI groups followed the World Health Organization classification. Hypocalcemia was defined as serum calcium ≤8 mg/dL. Calcium levels measured on postoperative day 0 and the following morning were compared between the BMI groups. RESULTS Of 1135 total thyroidectomy patients, 85% were women. The mean age and standard deviation of patients was 49 (± 13) y, with most of Hispanic origin (64%). Overall, 41.5% of patients had cancer, 45% nontoxic MNG, 5.8% toxic MNG, and 12% Graves' disease. Stratified by BMI, 27% of patients were normal, 34% overweight, and 39% obese. Overall, overweight and obese patients experienced less transient hypocalcemia at both time points compared to normal patients postoperatively (P = 0.01 and P = 0.009). Furthermore, overweight and obese patients with Graves' disease experienced less transient hypocalcemia at both time points (P = 0.04 and P = 0.05). There was no statistical difference in other groups. CONCLUSIONS A protective role of higher BMI or "obesity paradox" for postoperative hypocalcemia may exist in those obese patients after total thyroidectomy.

Abstract
Introduction and importance Granular cell tumor (GCT) is a rare neurogenic neoplasm originating from Schwann cells that predominantly affects women and can involve skin and mucousae. In the respiratory system it most frequently involves bronchi and larynx, while it is rare in the trachea. Case presentation A 26-year old female smoker was hospitalized for a suspected hypoechoic nodule in the right thyroid lobe closely adherent to the trachea. At preoperative computed tomography tracheal lumen was totally clear. The patient underwent a total thyroidectomy with lymph node dissection and tracheal shaving. The postoperative course was complicated by an extensive subcutaneous bilatreral emphysema associated with respiratory distress appeared on the fifth day. Bronchoscopy revealed a right anterolateral subcentimeter lesion near the second tracheal ring. Histologically, the diagnosis was consistent with a tracheal GCT developing into the thyroid parenchyma. The patient was discharged on the twentieth postoperative day. At the follow-up bronchoscopy the lesion was completely healed and at the last 12 month follow-up the patient is doing well. Clinical discussion Tracheal tumors are uncommon neoplasms accounting for about 2% of the total respiratory tree tumors. In literature we found <50 papers concerning tracheal GCT and in almost all of the cases patients complained about respiratory symptoms. Conclusion We report here a rare case of benign GCT of the trachea with extraluminal development, in a young patient who did not complain about preoperative respiratory symptoms, presented on ultrasound as a thyroid nodule with suspected cytology. Granular cell tumor is a rare neurogenic neoplasm involving unfrequently the trachea. In literature less than 50 papers concern these tracheal tumors. Respiratory symptoms are frequently complained by these patients. In this case we report a rare benign granular cell tumor of the trachea. The extraluminal development can simulate a thyroid tumor. Our patient underwent surgery on suspicion of neoplastic thyroid disease. The patient was not complaining of any respiratory symptoms. This occurrence has been described in less than 10 similar cases.

Abstract
Hypocalcemia is the most common complication after total thyroidectomy. The aim of this study was to determine the predictors of postoperative hypocalcemia requiring augmentation of routine calcium supplementation. Prospectively collected data of 61 patients who underwent total thyroidectomy from December 2018 to June 2019 was considered for the study. All patients received calcium and vitamin D supplementation after the surgery. In the postoperative period, serum calcium and parathormone (PTH) levels were monitored. The need of additional oral or intravenous (i.v.) calcium supplementation was evaluated as an outcome measure. This cohort comprised 61 patients with median age of 46 years (range 16-80 years) and 49 (80%) females. Central compartment clearance (CCC) was done in 32 patients. Escalation to increased oral and intravenous calcium was required in 15 patients (24.6%) and 2 patients (3.3%), respectively. Serum parathormone level of 11.5 pg/ml on postoperative day 1 predicted the requirement of additional calcium with a sensitivity of 82.4% and specificity of 77.3%. On univariate analysis, serum PTH (p < 0.001), CCC (p = 0.018), and intraoperative parathyroid gland congestion (p = 0.021) predicted the need for escalation of calcium supplementation. On multivariate analysis, only serum PTH showed a significant impact on the need for augmentation of calcium supplementation (p = 0.003). The need for calcium dose augmentation after total thyroidectomy was significantly associated with CCC, parathyroid gland congestion, and serum PTH levels. Intraoperative identification of parathyroid gland congestion and postoperative serum PTH levels is effective in predicting postoperative hypocalcemia with implications on time and cost.
