Which Is the Ideal Treatment for Benign Diffuse and Multinodular Non-Toxic Goiters?

Transcervical and robotic-assisted thoracoscopic resection of a substernal goiter

Several genetic and environmental factors contribute to the development of multinodular goitre. A transcervical surgical resection is recommended for larger goitres, though a minority of cases may require sternotomy or thoracotomy. We present a case of a posterior substernal goitre that was resected with combined transcervical and robotically assisted thoracic approaches. A woman in her 30s with an enlarging thyroid goitre elected to proceed with surgical resection. CT imaging demonstrated significant extension of the goitre into the posterior mediastinum and a staged approach was decided on. Both the initial transcervical thyroidectomy and the subsequent robotically assisted resection of the mediastinal portion were successful, without major complications. While most substernal goitres can be resected transcervically, certain rare anatomic features, such as extension into the posterior mediastinum, warrant consideration of a thoracic approach. Specifically, a robotic-assisted resection poses several advantages over traditional, more invasive approaches.

Thyroid dysfunction in Greece: Results from the national health examination survey EMENO

Background

Nationwide data on thyroid disease prevalence in Greece is lacking. Using the national health examination survey EMENO data resources, we aimed to estimate the prevalence of hypothyroidism and hyperthyroidism and associated risk factors in adults living in Greece.

Methods

A random sample of the adults (≥18 years) living in Greece was drawn by multi-stage stratified random sampling based on the 2011 census. During home visits, trained interviewers administered a standardized questionnaire to study participants. All participants answered questions concerning demographic parameters (e.g., age, sex, degree of urbanization, income) and questions concerning smoking habits, alcohol, dietary habits and psychological parameters such as anxiety and thyroid disease. Weighted logistic regression models were fitted to assess factors associated with thyroid disease.

Results

In total, 6006 individuals were recruited in the Greek Health Examination Survey EMENO (response rate 72%) of whom 5981 were eligible for this study. The prevalence of thyroid disease was 9%, where 0.4% was related to hyperthyroidism and 8.6% to hypothyroidism. The prevalence of thyroid disease was higher in women (14.9%) than men (2.7%) (p<0.001). The highest rates of thyroid disease were observed in former iodine-deficient areas. A decrease in the prevalence of thyroidopathies with increasing alcohol consumption was found. Thyroid disease was associated with anxiety in men. Multivariable regression analysis showed that age, geographic area, and smoking were related to thyroid disease.

Conclusion

The prevalence of thyroid disease in Greece is higher in women. Age, habits, and characteristics of geographic areas determine the distribution of thyroidopathies in Greece.

Impact of thyroidectomy on quality of life in benign goitres: results from a prospective cohort study

PURPOSE

Benign thyroid diseases encompass a large spectrum of conditions that are chronic and subtle in nature. A majority of patients choose non-surgical management and continue living their daily lives with subconscious impairment of optimal functioning. We studied the effect of thyroidectomy on the quality of life (QoL) in patients with benign goitres.

METHODS

A prospective study was conducted on 50 patients between January 2017 and August 2018 using the ThyPRO 39 questionnaire. This is a disease-specific health-related questionnaire administered the day before surgery and 6 months following surgery. Data analysis was performed using EpiData Manager and EpiData Entry Client (v 3.1).

RESULTS

The mean age of the cohort was 43.30 years ± 11.61, with a female preponderance (34:16). The most common indications for surgery were suspicion of malignancy and compressive symptoms in 34% and 30%, respectively. The most common histopathology reported was nodular/adenomatous hyperplasia (56%). Prior to surgery, the most common domains affected were emotional susceptibility and tiredness. Following surgery, a significant improvement in all domains of the ThyPRO 39 questionnaire were seen except for psychological well-being (p=0.126). In addition, the composite scores significantly improved (p<0.001). Younger age, female gender, and longer duration of goitre were the factors that significantly affected the outcomes in various domains.

CONCLUSION

Patients with benign goitres have subtle impairment of QoL which showed significant improvement following thyroidectomy.

Radiofrequency Ablation a Safe and Effective Treatment for Pediatric Benign Nodular Thyroid Goiter

Purpose: To evaluate the effectiveness of radiofrequency ablation (RFA) for benign thyroid nodules in pediatric patients. Materials and Methods: Twelve pediatric patients (11 female, 1 male; mean age 15.54 ± 2.8 years, range 10-19 years) with benign thyroid nodules (mean longest diameter 4.1 ± 1.4 cm, range 1.5-5.9 cm) treated by RFA from 2017 to 2020 were evaluated. The inclusion criteria for RFA therapy were (i) age < 20 years; (ii) benign cytological confirmation by 2 separate ultrasound guided fine-needle aspiration cytology (FNAC) or core needle biopsies; (iii) pressure symptoms or cosmetic problems caused by thyroid nodules; (iv) absence of any sonographic suspicious feature; and (v) follow-up for >6 months. Under local anesthesia, RFA was performed with the use of an RF generator and an 18-gauge internally cooled electrode. Volume changes in nodules on follow-up ultrasonography (US), changes in symptomatic and cosmetic scores, and complications arising during or after RFA were evaluated. Results: Mean follow-up period was 24.9 ± 13.9 months (range 6-43 months). At the last follow-up visits, volume of the nodule had decreased significantly (15.34 ± 11.52 mL vs. 4.07 ± 4.99 mL; P < 0.05), whereas volume reduction rate was 74.31% ± 19.59%. Both cosmetic and compressive symptoms were also significantly improved (2.91 ± 0.79 vs. 0.92 ± 0.67 and 1.5 ± 1.93 vs. 0.17 ± 0.39; P < 0.05). The mean number of ablation sessions was 1.4 ± 0.6 (range 1-3 sessions), and one of the patients suffered from transient vocal cord palsy which was spontaneously resolved 53 days later. Conclusions: RFA is a safe and effective treatment for benign thyroid nodules in pediatric patients, and can thus serve as an alternative treatment for thyroidectomy.

A Review of the Pathology, Diagnosis and Management of Colloid Goitre

Colloid goitres are a common, benign lesion of the thyroid gland, that involve a diffuse or nodular pattern. An important feature of colloid goitre is the contained colloid material inside and the comet-tail artefacts, which show up on ultrasound. However, some cases of colloid goitre do not show a comet-tail sign and sometimes these artefacts need to be distinguished from microcalcifications in malignant lesions. This review discusses the epidemiology, pathophysiology, clinical manifestations, ultrasound features and management of colloid goitres.

[The thyroid gland in old age : Physiology and pathology]

In healthy older people the metabolism of thyroid hormones is physiologically altered and can possibly even actively contribute to longevity. This should also be taken into consideration in the treatment of diseases of the thyroid and principally also for younger patients. For example, with progressing age comorbidities become more prevalent and especially in cardiovascular diseases, hyperthyroidism is less well tolerated, and should be treated more aggressively. Benign multinodular goiter also becomes more prevalent in old age and should be surgically treated when causing mechanical symptoms. The treatment concept for malignant diseases should be adapted to the holistic situation of the patient but principally in the same manner as in younger patients. Old and very old patients also benefit from adequate, risk-adapted treatment of thyroid gland diseases so that appropriate diagnostics and clarification are meaningful, regardless of age.
