The patient was a 61-year-old woman with thyroid enlargement since her 20s. She began to fall down repeatedly towards the end of June 2015. She was admitted to our hospital in the middle of August because of difficulty in walking. Upon admission, she presented with neck tremor and was unable to maintain a sitting position due to ataxia of the trunk and limbs. We studied serum anti-neuronal antibodies and obtained a positive result for anti-amphiphysin antibody (AMPH-Ab). Cerebrospinal fluid analysis revealed elevated protein levels and IgG index...

Inflammation has long been associated with the thyroid and with thyroid cancers, raising seminal questions about the role of the immune system in the pathogenesis of advanced thyroid cancers. With a growing understanding of dynamic tumour-immune cell interactions and the mechanisms by which tumour cells evade antitumour immunity, the field of cancer immunotherapy has been revolutionised. In this Review, we provide evidence to support the presence of an antitumour immune response in advanced thyroid cancers linked to cytotoxic T cells and NK cells...

PURPOSE: To study the effects of gestational transient thyrotoxicosis (GTT) on pregnancy outcomes. METHODS: This case-control study retrospectively analyzed 7976 women with singleton pregnancies whose thyroid function was measured before 16 weeks of gestation and who delivered at ≥22 weeks of pregnancy. GTT was defined as hyperthyroidism (free thyroxine [FT4] level: ≥95th percentile) in the early pregnancy, which normalized in mid-pregnancy without thyroid-stimulating hormone receptor antibodies...

Contact-dependent (juxtacrine) signaling is important for local cell-to-cell interaction and has received attention in recent years regarding its role in pituitary function, differentiation, and development. This study investigated one of the juxtacrine-related molecules, thymocyte differentiation antigen 1 (THY1), in the anterior lobe of the rat pituitary gland. Western blot analysis revealed expression of the THY1 protein in the adult rat anterior lobe. We also found that the THY1 ligand, integrin-β2 (ITGB2), is also expressed in the pituitary gland...

BACKGROUND: Graves' disease (GD) and Hashimoto's disease (HD) are autoimmune thyroid diseases distinguished by the presence or absence of an anti-thyroid stimulating hormone receptor (TSHR) antibody (TRAb). TSHR gene polymorphisms determine the amount of TSHR expressed, which may in turn influence TRAb production. The FANTOM5 project identified six GD-associated SNPs within the enhancer regions of TSHR and unknown genes. In this study, we examined the association of 11 TSHR and unknown gene polymorphisms, 5 of which are located in TSHR enhancer regions, with the development and prognosis of GD and HD...

Background Though iodine deficiency in pregnancy is a matter of public-health concern, a functional measure of iodine status is lacking. The thyroid-specific protein, thyroglobulin (Tg), which reflects thyroid size, has shown promise as a functional measure in studies of children and adults, but data in pregnancy are sparse. In a cohort of mildly-to-moderately iodine-deficient pregnant women, we aimed to explore whether serum Tg is a sensitive functional biomarker of iodine status and to examine longitudinal change in Tg with gestational age...

We report a patient with resistance to thyroid hormone beta caused by a novel <i>THRB</i> gene mutation and coexisting pituitary microadenoma. A 41-year-old Thai woman presented with elevated serum thyroid hormone levels and non-suppressed TSH. MRI showed a 4x2-mm pituitary adenoma. Five of her relatives had similar thyroid tests abnormalities, but a sister had Graves' disease. TPO and TG antibodies were positive in all affected family members except for a 4.5 year-old. Lack of thyrotoxic symptoms and TSH suppression by T3, indicated incidentaloma rather than a TSH-secreting pituitary adenoma...

INTRODUCTION: Chronic lymphocytic thyroiditis [Hashimoto thyroiditis (HT)] is a common thyroid lesion diagnosed on fine-needle aspiration cytology (FNAC). Apart from FNAC, various other parameters, such as clinical features, ultrasonographic findings, antithyroid antibody levels, hormone profiles, and radionuclide thyroid scan, are also taken into consideration in making a diagnosis of HT. AIMS: To grade lymphocytic thyroiditis based on the cytomorphology and to correlate the cytological grades with the levels of antithyroid peroxidase antibody (ATPO), antithyroglobulin antibody (ATG), and thyroid stimulating hormone (TSH)...

CONTEXT: Thyroperoxidase antibody (TPOAb) positivity is the main risk factor for thyroid dysfunction during pregnancy and is consistently associated with premature delivery. However, the underlying mechanism is currently unknown. We hypothesized that TPOAb positivity may interfere with gestational thyroid stimulation induced by the pregnancy hormone human chorionic gonadotropin (hCG). DESIGN, SETTING AND PARTICIPANTS: TSH, FT4, TPOAbs and/or hCG concentrations were measured in early and late pregnancy of 7587 pregnant women from two Dutch population-based prospective cohorts (N=5924 Generation R; N=1663 HAPPY)...

BACKGROUND: For patients with lung metastases of differentiated thyroid carcinoma (DTC), there is no consensus on the maximal size of metastatic lesions to use when determining the intensity of follow-up and additional therapeutic options. We evaluated the clinical outcomes and survival of patients with metastatic DTC confined to the lung, using the maximal diameter of lung lesions in the initial computed tomography (CT). METHODS: This retrospective cohort study included 112 DTC patients with metastases confined to the lung...

The increasing detection of papillary thyroid microcarcinoma (PTMC) has created management dilemmas. To clarify the clinical significance of postsurgery stimulated thyroglobulin (ps-Tg) in PTMC who undergo thyroidectomy and radioactive iodine (RAI), we retrospectively reviewed the 358 PTMC patients who were treated with RAI and followed up in our hospital. Those with an excessive anti-Tg antibody, ultrasound-detected residual were excluded, thereby resulting in the inclusion of 280 cases. Their clinical and histopathological information and clinical outcomes were collected and summarized...

Hashimoto's encephalopathy is a rare, imprecisely defined autoimmune neurologic syndrome associated with Hashimoto's thyroiditis that normally responds to corticosteroids. Here, we describe the case of a 55-year-old woman who presented with subacute cognitive decline and ataxia. Neoplastic, paraneoplastic, infectious, and metabolic etiologies were ruled out. Anti-TPO antibody level was markedly elevated at 966U/mL. After one month of 60mg/day of oral prednisone, she felt back to baseline and her Montreal Cognitive Assessment dramatically improved...

Subclinical hypothyroidism has been found to be associated with adverse reproductive outcomes, such as infertility, miscarriage, preterm birth, and complications of pregnancy. Multiple studies have investigated the relationships between thyroid function, thyroid antibodies, fertility, and pregnancy. Thyroid autoimmunity is the most common cause of hypothyroidism in iodine-sufficient locations. Thyroid antibodies have been associated with adverse reproductive outcomes such as miscarriage and infertility. Debate exists regarding the method of identification of thyroid dysfunction in pregnancy, which can be conducted by targeted screening or by universal screening...

Overt hypothyroidism in pregnancy, defined as an elevated serum thyroid-stimulating hormone (TSH) and reduced serum free thyroxine or a TSH >10 mIU/L, is known to have adverse effects on pregnancy. Subclinical hypothyroidism is typically defined as an elevated TSH and normal FT4 levels. There remains much controversy on the benefit of starting levothyroxine for mothers diagnosed with subclinical hypothyroidism. Recent studies are redefining the normal range for TSH in pregnancy, and the data on whether treatment of subclinical hypothyroidism improves outcomes for the mother and fetus are unclear...

Nivolumab (Opdivo(®) ), pembrolizumab (Keytruda(®) ), atezolizumab, and pidilizumabab are anti-PD1 monoclonal antibodies. Nivolumab is licensed in advanced melanoma and second-line therapy of advanced or metastatic non-small cell lung cancer. When activated, the programmed cell death (PD)-1 is implicated in the inhibition of the immune system. Anti-PD1 removes this inhibition and allows the immune system to control tumour cell progression.(1-4) Immune-mediated toxicity of this treatment have been reported, either organ-specific toxicities - i...
