Neonatal screening for hyperthyroidism
Hyperthyroidism in newborns is seen in 1:5600 live births, although severe cases requiring treatment is much less common and is seen in 1:12,174 live births. Around 25% of severe neonatal hyperthyroidism leads to increased early death from congestive heart failure and premature birth. This study examines samples from the neonatal TSH screening program in France to determine a threshold to identify babies with neonatal hyperthyroidism.

THYROID AND PREGNANCY
Is thyroid autoimmunity still a risk factor in women undergoing fertility treatment?
Thyroid autoimmunity has for many years been considered associated with a poor outcome in women undergoing fertility treatment. Recent studies now question this association in women who have normal thyroid function. This study investigated the association of thyroid autoimmunity with fertility treatment and live birth rates in a group of infertile women with normal thyroid function and positive thyroid antibodies.

Total thyroidectomy improves quality of life in children and adolescents with Graves’ disease
Pediatric Graves’ disease is rare, but it is associated with hyperthyroid symptoms that may significantly affect psychosocial and physical functioning. As is the case in adults, thyroid surgery is an effective treatment option in children and adolescents, although less utilized than antithyroid drugs and radioactive iodine therapy. The goal of this study was to describe the impacts on quality of life of total thyroidectomy in children with Graves’ disease.

The relationship between surgeon volume and outcomes of parathyroid surgery
High calcium levels from primary hyperparathyroidism and can lead to health problems such as thinning of the bones and kidney stones. The main treatment for hyperparathyroidism is surgery to remove the overactive gland, called a parathyroidectomy. The goal of this study was to investigate the relationship between surgeon volume and patient outcome for parathyroid surgery.

How many thyroid cancer patients on levothyroxine are meeting their treatment goals?
The goal of thyroid hormone therapy in thyroid cancer is to keep the TSH within a certain range to prevent any stimulation of growth of any remaining thyroid tissue by increased levels of TSH. The current American Thyroid Association provides treatment ranges/goals for TSH levels based on risk of the cancer returning. This study was done to evaluate whether patients with thyroid cancer who have undergone surgery for this disease and are now being treated with levothyroxine are meeting their goal TSH level as per current clinical guidelines.

Molecular tests improve the detection of medullary thyroid cancer for patients with thyroid nodules
Diagnosing medullary thyroid cancer (MTC) on thyroid biopsies is challenging; more than 50% of MTCs are missed. Failure to identify MTC in a thyroid nodule prior to surgery can result in insufficient initial thyroid surgery with a lower chance of cure and the need for re-operations. The aim of this study is to report the development of and evaluate the performance of a commercially available MTC classifier.
