INTRODUCTION
Nontoxic nodular goiter is one of the most prevalent thyroid conditions worldwide. Thyroidectomy for large goiters has a relatively high risk of postoperative airway obstruction, with tracheomalacia being one of the potential complications.
CASE REPORT
A 61-year-old woman complained of a lump in her neck for 45 years. The node is progressively enlarged, but she did not experience any breathing difficulty, hoarseness, or pain while swallowing. A total thyroidectomy was then performed. The histopathologic examination revealed colloid goiter. During the procedure, evaluation of the trachea revealed a tracheomalacia, so a tracheotomy was then performed on the patient. After a follow-up period of three months, the patient was no longer experiencing tracheomalacia, and the tracheostomy was successfully closed.
DISCUSSION
Surgery has been considered an acceptable approach for managing non-toxic goiter. The most common indications are compressive symptoms, substernal extension, inability to control hyperthyroidism through medication, and a suspicion of malignancy. However, thyroidectomy for large goiter carries a relatively high risk of postoperative respiratory obstruction. Diagnosing tracheomalacia can be challenging and often relies on bronchoscopy to assess the airway and observe the collapse of cartilage and membranes. Acquired tracheomalacia can be managed through internal or external stenting or tracheostomy.
CONCLUSION
Total thyroidectomy has been recommended as a suitable procedure for non-toxic and toxic multinodular goiter. Tracheomalacia may occur following thyroidectomy in patients with thyroid enlargement. Tracheostomy effectively manages tracheomalacia by creating a channel across the malacia's focal segment, restoring the airway's patency.

Archives of Iranian Medicine Jun 2023Based on the critical role of MT4-MMP and MT6-MMP in carcinogenesis, we focused on MT4-MMP and MT6-MMP circulating levels in patients with thyroid nodules.
BACKGROUND
Based on the critical role of MT4-MMP and MT6-MMP in carcinogenesis, we focused on MT4-MMP and MT6-MMP circulating levels in patients with thyroid nodules.
METHODS
Plasma samples were collected from three groups, including papillary thyroid cancer (PTC; n=30), multinodular goiter (MNG; n=30), and healthy subjects (n=22). Enzyme-linked immunosorbent assay (ELISA) was used to obtain the concentration of MT4-MMP and MT6-MMP in the three groups.
RESULTS
Analysis of data demonstrated increased levels of MT4-MMP (PTC: 4.90±1.35, MNG: 4.89±1.37, and healthy: 3.13±1.42) and MT6-MMP (PTC: 8.29±2.50, MNG: 7.34±2.09, and healthy:5.01±2.13) in thyroid nodules by comparison with healthy subjects (<0.05). There were no significant differences in the levels of the two MT-MMPs between PTC and MNG (>0.05). Increased plasma levels of MT4-MMP (odds ratio=2.48; 95% CI: 1.46-4.19; =0.001) or MT6-MMP (odds ratio=1.81; 95% CI: 1.29-2.53; =0.001) were associated with increased risk of PTC tumorigenesis. Interestingly, a strong positive association was observed between MT4-MMP and MT6-MMP in the three groups (PTC: r=0.766**, =0.000; MNG: r=0.856**, =0.000; healthy r=0.947**, =0.000). Areas under the ROC curve for MT4-MMP and MT6-MMP were 0.82 and 0.96, respectively. At the cutoff value>4.7 (ng/mL), MT4-MMP and MT6-MMP showed a sensitivity of 63.3% and 90.0%, respectively, with 100% specificity.
CONCLUSION
Our work has led us to imply that the higher levels of MT4-MMP and MT6-MMP are closely linked with both PTC and MNG tumorigenesis. They may probably promote the development of thyroid lesions; however, more research is needed to further clarify the current findings.

We aimed to evaluate the use of cost-effective NLR (Neutrophil Lymphocyte Ratio) in determining the prognosis and recurrence risk of thyroid papillary carcinoma patients. This retrospective, cross-sectional and single-center study was carried out in the Department of General Surgery, Istanbul Gaziosmanpaşa Training and Research Hospital. Between 2018 and 2021, who were diagnosed with papillary thyroid cancer and underwent total thyroidectomy, and patients who underwent total thyroidectomy due to multinodular goiter were analyzed. For patients in the malignancy group, the NLR cutoff value was determined as 1.73, the sensitivity was calculated as 51.77% and the specificity as 86.15%. NLR in the malignant group was found to be 9.5 times higher than the NLR in the control group (Odds Ratio: 9.5). A statistically significant difference was found between NLR and papillary thyroid carcinoma prognostic classification systems (AJCC/TNM, AMES, and MACIS). NLR medians differ according to ATA recurrence risk classification (P = .020). According to the results we obtained in our study, we believe that cost-effective NLR can be a useful indicator in terms of predicting malignancy in a patient with thyroid nodule and in determining the prognosis and risk of recurrence in patients with thyroid papillary carcinoma.

OBJECTIVE
Few studies used all nodule burdens to specify the prognosis of multinodular goiter (MNG) following radiofrequency ablation (RFA), so this study addresses this question for MNG after completely ablating dominant nodules.
METHODS
The RFA indications for MNG included a total of 2-5 benign nodules with over 50% normal tissue on ultrasound, 1-3 well-defined benign dominant nodules on cytology, largest diameter ≥20 mm and/or with clinical complaints, and patient refusal or unable of surgery. A retrospective study of 185 MNG patients with completely ablated dominant nodules in a single-session RFA was conducted. The efficacy and complications were evaluated at 1, 6, 12 months and yearly thereafter. Based on retreatment risks, progressive disease (PD), stable disease (SD) and complete relief (CR) were introduced to assess all nodule load changes. PD was clarified as having new/non-target nodules newly appeared to ACR TI-RADS≥4, or new/enlarged non-target nodules ≥1 cm.
RESULTS
The initial ablation ratios of target nodules were 100% at one month. During a mean 22.38±13.75 months (range, 12-60 months), the VRR of ablated nodules was 98.25% at 24 months without regrowth. Cosmetic and symptomatic scores decreased to 1 and 0, respectively, after 48 months. 9.7% of patients (18/185) had PD and the retreatment rate was 2.2% (4/185). The complication rate was 2.7% (5/185).
CONCLUSIONS
RFA provides cosmetic and symptomatic relief for an average of two years. RFA is an useful minimally invasive treatment modality for selected MNG patients.

BACKGROUND
Thyroid storm is a potentially fatal thyrotoxicosis triggered by an event, such as manipulation of the thyroid gland, acute iodine load, trauma, or infection. Prior to deciding on fine needle aspiration (FNA) biopsy, patients who have been diagnosed with hyperthyroidism or low thyroid stimulating hormone and multinodular goiter (MNG) should be imaged via radionuclide thyroid scan.
CASE DESCRIPTION
We present a case of a 62-year-old female patient with history of MNG, who had thyrotoxicosis on presentation due to medication noncompliance and was found to have Graves' disease. Computed tomography scan without intravenous iodine contrast injection showed a heterogeneously appearing and notably enlarged thyroid gland with a 6.2 cm × 5.8 cm right thyroid lobe and 5.5 cm × 5.0 cm left lobe. There was a resultant narrowing of the trachea measuring 6 mm in the transverse dimension at its narrowest point. Further evaluation with dedicated ultrasound of the thyroid showing bilateral MNG with coarse calcifications as well as a notable left thyroid cyst measuring 1.6 cm × 1.2 cm × 2.3 cm, isoechoic, with smooth margins. The patient was started on methimazole 40 mg/day, cholestyramine 4 mg four times per day, prednisone 20 mg/day, saturated solution of potassium iodide 50 mg three times daily, and propranolol for heart rate control. Another service recommended FNA biopsy of the right 3 cm thyroid nodule. Two days after undergoing an FNA, she experienced a thyroid storm, requiring emergent total thyroidectomy as a life-saving procedure.
CONCLUSIONS
FNA is rarely needed in the case of a hyperfunctioning thyroid nodule, as it can be seen on radionuclide thyroid scan. However, when executed, a euthyroid state needs to be achieved before attempting to perform an FNA. Total thyroidectomy is warranted in a hyperthyroid state in an emergent setting without ample time for medical therapy to be effective, as seen in our reported case.

Tracheobronchial ruptures can be extremely dramatic and life threatening and are encountered in approximately 5 out of 100,000 cases after orotracheal intubation. They can occur as a result of intubation, tracheostomy, and bronchoscopy. In this case report, we presented a 56-year-old female patient with a history of thyroid surgery 27 years prior who presented to our clinic with recurrent multinodular goiter. The patient underwent a complementary complication-free thyroidectomy assisted by intermittent intraoperative nerve monitoring. After hemostasis, final controls involving digital palpation of the possible remnants of the thyroid gland and a search for pathological lymph nodes in the central compartments, a mass structure with a rubbery consistency suspicious for residue thyroid tissue was palpated in both posterolateral aspects of the trachea, but more prominently in the left. The anesthesia team was asked to decrease the cuff pressure, assuming that the palpated mass could be the cuff of the endotracheal tube, and the mass was noted to shrink. The membranous tracheal rupture due to the endotracheal tube cuff was closed with sutures running superiorly, and a superiorly based strap muscle flap was placed over during thyroid surgery. The patient was discharged on day 7. A simple routine digital examination by the attending surgeon dealing with the thyroid surgery would contribute favorably to prognosis, as such a precaution would allow early repair in cases where such injuries occur.

Unsuspected thyroid cancer can be detected in multinodular goiter (MNG) where the risk of malignancy is 7-9%. Fine needle aspiration (FNAc) is performed in case of suspicious findings on ultrasound. With benign FNAC results there is no need for surgery unless the patient has pressure symptoms or cosmetic concerns, but the risk of overlooked malignancy is always present. We present the case of a patient with unexpected detection of papillary thyroid cancer on thyroid scan.

Review
Normal thyroid hormone levels are crucial for the homeostasis of many metabolic cycles and processes throughout the human body. Thyroid dysfunction, such as thyrotoxicosis, can result from many different etiologies, including Graves' disease (GD), toxic multinodular goiter (MNG), and toxic adenoma. These hyperthyroid disease states can cause devastating complications and disease, including the disruption of the bone remodeling cycle and skeletal development, which can result in osteoporosis. Osteoporosis is characterized by a decrease in bone mineral density and a propensity for fragility fractures. In addition to patients with overt hyperthyroidism, studies have provided evidence of other high-risk patient demographics, such as individuals with subclinical hyperthyroidism and postmenopausal women, who may be at an increased risk for the development of secondary osteoporosis. The treatment of patients with hyperthyroid-induced osteoporosis often requires a multifaceted management plan that may be unique to each patient's situation. Antithyroid therapy is often the first step in treating this disease and may include thioamide medications. Radioactive iodine-131 therapy (RAI) and the surgical removal of the thyroid gland may also be reasonable approaches for restoring normal thyroid function. Following thyrotoxicosis mitigation, antiresorptive drugs such as bisphosphonates, calcitonin, and selective estrogen receptor modulators (SERMs) may be used to counteract decreased bone mineral density (BMD). Additionally, the implementation of vitamin D, calcium supplements, and weight-bearing exercise may also reduce bone loss. While the effects of thyroid stimulating hormone (TSH) and triiodothyronine (T3) on bone remodeling have been studied in the past, more research is needed to identify unknown mechanisms and develop future improved treatments for this condition.

Clinical Case Reports Dec 2023Prompt coordinated care enables vaginal delivery for severe goiter-induced airway compression in late pregnancy when expectant management is precluded.
KEY CLINICAL MESSAGE
Prompt coordinated care enables vaginal delivery for severe goiter-induced airway compression in late pregnancy when expectant management is precluded.
ABSTRACT
Long-standing neglected multinodular goiter rarely causes life-threatening airway compression in late pregnancy. Most cases report cesarean delivery to relieve respiratory distress. Vaginal birth may also be possible, but the evidence is limited. A 30-year-old woman with a 7-year goiter history developed severe dyspnea at 34 weeks gestation. Despite the risks, labor was induced by urgent decompression. She vaginally delivered a premature but healthy infant. Her breathing improved after delivery. She later underwent an uncomplicated thyroidectomy. With careful selection and monitoring, vaginal delivery can be considered for goiter-induced respiratory compromise when expectant management is precluded. This case demonstrates successful urgent decompression and favorable maternal-fetal outcomes are possible with a coordinated approach despite the high-risk scenario.

BACKGROUND
Papillary thyroid carcinoma (PTC) is the most frequent thyroid malignancy. Histopathological examination is widely accepted as the gold standard test for the diagnosis of PTC. However, the histopathological examination sometimes can't differentiate PTC from other thyroid diseases. Differentiating PTC from other thyroid diseases is essential for a therapeutic approach and prognosis.
OBJECTIVES
The current study was performed to investigate the utility of TROP-2, SPL-2, and CXCL12 mRNA and protein expression in discriminating PTC from other thyroid diseases that mimic PTC.
METHODS
The current study was performed on 75 cases of surgically resected thyroid glands. The cases were distributed in two groups: the PTC group and the non-PTC group. The PTC group consisted of 35 cases (25 patients of the classic PTC variant and 10 patients of the PTC follicular variant). The non-PTC group consisted of 40 cases (10 cases were multinodular goiter, 5 cases were Graves' disease, 5 cases were Hashimoto thyroiditis, 15 patients were follicular adenoma (FA) and 5 cases were follicular carcinoma). TROP-2, SPL-2, and CXCL12 mRNA expression were estimated by qRT-PCR, and protein expression was estimated by immunohistochemistry.
RESULTS
There were upregulated TROP-2, SPL-2, and CXCL12 mRNA and protein expressions in PTC compared to non-PTC (P< 0.001, for each). There was a statistically significant upregulation in the mRNA expression of the three genes among PTC cases with larger tumor sizes (P< 0.001, for each), those with tumor stages III and IV (P= 0.008, 0.002 and < 0.001 respectively), and those with LN metastasis (P< 0.001, for each). Moreover, there was a statistically significant upregulation in CXCL-12 gene expression among PTC cases with extra-thyroid extension (P< 0.001).
CONCLUSION
mRNA expression of TROP-2, SPL-2, and CXCL12 among PTC cases increased in larger tumor size, tumor stages III and IV, and LN metastasis. Moreover, there was an increase in CXCL-12 gene expression among PTC cases with extra-thyroid extension. Thus, TROP-2, SPL-2, and CXCL12 expressions could be possible diagnostic and prognostic markers in PTC.
