S Allelein, J Feldkamp, M Schott
Autoimmune diseases of the thyroid gland are considered to be the most frequent cause of thyroid gland disorders. Autoimmune thyroid diseases consist of two subgroups: autoimmune thyroiditis (AIT) and Graves' disease. The AIT is the most common human autoimmune disease. Infiltration of the thyroid gland with cytotoxic T‑cells can lead to an initial thyrotoxicosis und during the course to hypothyroidism due to destruction of the thyroid gland. Substitution with Levothyroxine is indicated for manifest hypothyroidism and subclinical hypothyroidism with increased thyroid antibodies with the intention of normalizing the serum thyroid stimulating hormone (TSH)...

BACKGROUND: We aimed to establish the changes in the incidence and characteristics of iodine-induced hyperthyroidism (II-Hyper) and iodine-induced hypothyroidism (II-Hypo) in the two-year period before and the ten-year period after the increase in mandatory salt iodization from the previous 10 mg of potassium iodide to 25 mg per kg in 1999. Furthermore, we aimed at determining the duration of treatment in II-Hyper patients, since no data regarding severity and treatment of II-Hyper with respect to iodine supply are available...

RATIONALE: Pregnancy is a complicated physiological process. Physiological leukocytosis often takes place and it is primarily related to the increased circulation of neutrophils, especially during the last trimester of pregnancy. Noncongenital agranulocytosis during pregnancy is rare and reported only occasionally, while in most of the cases, the agranulocytosis has already occurred prior to pregnancy or induced by identified factors such as antibiotics, antithyroid agents, or cytotoxic agents...

BACKGROUND: PD-1 blockade therapies have demonstrated durable responses and prolonged survival in a variety of malignancies. Treatment is generally well tolerated, although immune-related adverse events (irAEs) can occur. Autoimmune thyroid dysfunction is among the most common irAE, but an assessment of the clinical, mechanistic, and immunologic features have not been previously described. PATIENT AND METHODS: Patients with advanced non-small cell lung cancer (NSCLC) treated with pembrolizumab at Memorial Sloan Kettering Cancer Center (N=51) as part of KEYNOTE-001 (NCT01295827) were included...

Fetal and neonatal autoimmune hyperthyroidism is a rare, serious but transient disorder. Early diagnosis and treatment are key objectives for an optimal prognosis and the well-being of the child. This review focuses on the management of these patients during the fetal and neonatal periods. We propose a diagnostic algorithm for high-risk pregnancies in mothers with current or past hyperthyroidism related to Graves' disease, involving repeated fetal thyroid gland assessments from 20 weeks of gestation onwards and maternal serum thyroid-stimulating hormone receptor antibody (TRAb) determination, with close monitoring if TRAb levels exceed 2 to 3 times the upper limit of the normal range...

Graves disease is rarely complicated with cerebrovascular steno-occlusive diseases. Previous studies have suggested several hypotheses for this occurrence, including excess thyroid hormone, which stimulates the sympathetic nervous system, which in turn causes an abnormal hemodynamic response with consequent atherosclerotic changes, and antithyroid antibodies cause local vascular inflammation in patients with Graves disease. However, radiological findings of vasculitis in patients with Graves disease and cerebral infarction remain less known...

INTRODUCTION: Pituitary disorders during pregnancy are uncommon. The approach should include a close follow-up in order to reduce maternal and fetal risks associated with physiological changes during pregnancy or treatment side effects. MATERIALS AND METHODS: We report a 21-year-old woman with a thyroid-stimulating hormone-secreting pituitary macroadenoma and positive antithyroid antibodies. She was initially treated using transsphenoidal pituitary surgery. The patient relapsed 17-month post-surgery...

Familial dysalbuminemic hyperthyroxinemia (FDH) is an autosomal dominant condition and is the most commonly inherited euthyroid hyperthyroxinemia in Caucasians. However, it is extremely rare in Asian populations. A 30-year-old Japanese woman, who was incidentally found to have apparent thyroid dysfunction, was admitted to our hospital in 2004. She had extremely elevated serum free thyroxine (FT4), moderately elevated free triiodothyronine (FT3), and normal thyroid-stimulating hormone (TSH). Clinical thyroid examination revealed no abnormalities other than small goiter...

: We describe the case of a young Hispanic female who presented with thyrotoxicosis with seizures and ischemic stroke. She was diagnosed with a rare vasculopathy - moyamoya syndrome. After starting antithyroid therapy, her neurologic symptoms did not improve. Acute neurosurgical intervention had relieved her symptoms in the immediate post-operative period after re-anastomosis surgery. However, 2 post-operative days later, she was found to be in status epilepticus and in hyperthyroid state...

Objective When patients with Graves' disease show severe allergic cutaneous reactions, physicians often suggest that they undergo radioiodine therapy instead of receiving propylthiouracil (PTU), another antithyroid drug, because anti-neutrophil cytoplasmic antibody (ANCA) -related vasculitis can occur with PTU, especially with long-term use. However, some patients refuse radioiodine therapy and chose PTU. Sometimes PTU treatment may be prolonged. Since the frequency of adverse effects of methimazole (MMI) is dose-related, there is a possibility that we can re-administer a low dose without adverse effects to patients well-controlled with PTU who once experienced an allergic reaction to MMI...

Primary squamous cell carcinoma of the thyroid is a very rare thyroid malignancy (less than 1% of thyroid cancers) with unfavorable clinical evolution and median survival less than one year, due to highly local tumor invasiveness with airway obstruction, metastases and treatment complications. We present a 62-year-old female patient with a fixed, rapidly increasing 5 cm right thyroid nodule, generating compressive signs and significant weight loss, resembling anaplastic thyroid carcinoma. Thyroid hormones, antithyroid antibodies and calcitonin were normal...
