Thyroid disease in pregnancy is a common clinical problem. Since the guidelines for the management of these disorders by the American Thyroid Association (ATA) were first published in 2011, significant clinical and scientific advances have occurred in the field. The aim of these guidelines is to inform clinicians, patients, researchers, and health policy makers on published evidence relating to the diagnosis and management of thyroid disease in women during pregnancy, preconception, and the postpartum period. ⋯ We have developed evidence-based recommendations to inform clinical decision-making in the management of thyroid disease in pregnant and postpartum women. While all care must be individualized, such recommendations provide, in our opinion, optimal care paradigms for patients with these disorders.

Patients with hoarseness of voice, previous neck operation, or suspicion of malignancy are at high risk of having pre-thyroidectomy vocal cord (VCP) palsy. Therefore, vocal cord (VC) functions should be evaluated before surgery. This study aimed to evaluate the accuracy of hoarseness, a voice-related questionnaire (Voice Handicap Index [VHI]-30), and transcutaneous laryngeal ultrasound (TLUSG) in diagnosing VCP, as well as the role of TLUSG in the evaluation of high-risk patients. ⋯ TLUSG is a feasible, non-invasive, and sensitive tool in detecting VCP in high-risk patients. It has safely precluded 87.7% high-risk patients from laryngoscopy. TLUSG should be incorporated as a part of the ultrasound examination of the thyroid.

The incidence of thyroid cancer has increased worldwide. The country where the incidence has increased most is South Korea. The goal of this study is to understand the magnitude of association between opportunistic thyroid cancer screening and thyroid cancer incidence, thyroid cancer subtype, and disease-specific mortality. ⋯ The magnitude of association between thyroid cancer screening in South Korea and the incidence of thyroid cancer strongly suggests that screening is the most important driver of the epidemic of thyroid cancer, particularly among females. Thyroid cancer screening, however, was only associated with the increase of one tumor histology, papillary thyroid cancer, and it did not have any association with thyroid cancer mortality. The extent to which opportunistic thyroid cancer screening is converting thousands of asymptomatic persons to cancer patients without any known benefit to them needs to be examined carefully.

Fine-needle aspiration (FNA) of thyroid nodules is commonly performed, and despite the use of ultrasound (US) guidance, the rate of non-diagnostic FNAs is still significant. The risk of malignancy of thyroid nodules with a non-diagnostic FNA is not clearly defined. However, most studies exclude the majority of patients without a repeat biopsy or surgery, thus increasing the likelihood of selection bias. The aims of this study were to determine the malignancy risk in nodules with an initial non-diagnostic FNA, and to identify the factors associated with malignancy. ⋯ The prevalence of thyroid cancer in nodules with non-diagnostic results is lower than the malignancy rate in thyroid nodules in general, but not negligible. They should be followed as per guidelines with heightened suspicion for nodules containing calcifications. Nodules with repeatedly non-diagnostic FNA results especially in the absence of calcifications have a low risk of malignancy and may be observed.
