Selim Kurtoğlu, Ahmet Özdemir
Fetal and neonatal hyperthyroidism may occur in mothers with Graves' disease. Fetal thyrotoxicosis manifestation is observed with the transition of TSH receptor stimulating antibodies to the fetus from the 17th-20th weeks of pregnancy and with the fetal TSH receptors becoming responsive after 20 weeks. The diagnosis is confirmed by fetal tachycardia, goiter and bone age advancement in pregnancy and maternal treatment is conducted in accordance. The probability of neonatal hyperthyroidism is high in the babies of mothers that have ongoing antithyroid requirement and higher antibody levels in the last months of pregnancy...

INTRODUCTION: Testis was considered unresponsive to thyroid hormone for a long time. However, like in animals, the presence of thyroid hormone receptors in different testicular cell types was demonstrated also in humans. Accordingly, thyrotoxicosis and hypothyroidism have remarkable effects on testicular function and more extensively on fertility. REVIEW: Thyrotoxicosis and hypothyroidism are associated with changes affecting the endocrine, sexual, or reproductive functions...

OBJECTIVE: Amiodarone is used for the maintenance of sinus rhythm in patients with arrhythmias, but thyroid dysfunction (amiodarone-induced thyrotoxicosis(AIT) or -hypothyroidism(AIH)) is a common adverse effect. Since the onset of AIT and AIH may be unpredictable, the value of long-term regular monitoring of amiodarone treated patients for thyroid dysfunction is still uncertain. DESIGN: We retrospectively documented the frequency at which overt thyroid dysfunction was preceded by subclinical thyroid dysfunction...

Amiodarone-induced thyroid dysfunction occurs in about 15-20% of patients under amiodarone therapy. Amiodarone-induced hypothyroidism (AIH) can develop in patients with an apparently normal thyroid gland or in those with an underlying chronic autoimmune thyroiditis. On a clinical ground, AIH is not challenging and can be easily treated with L-thyroxine therapy. Amiodarone-induced thyrotoxicosis (AIT) can occur in patients with (AIT 1) or without (AIT 2) an underlying thyroid disease. AIT 1 is a true iodine-induced hyperthyroidism occurring in patients with an underlying thyroid autonomy while AIT 2 is a drug-induced destructive thyroiditis...

We report the case of a 61-year-old woman with persistent thyrotoxicosis for 7 years despite low thyroidal radioiodine uptake and methimazole treatment. Her initial I whole-body scan (WBS) was read as negative. Upon evaluation in our institution, she remained hyperthyroid after discontinuation of methimazole. Repeat WBS with SPECT/CT revealed low 24-hour thyroidal uptake (RAIU = 2%) and intensely focal radioiodine uptake in a large heterogeneous left pelvic mass, consistent with left adnexal struma ovarii. Resection of this mass confirmed benign struma ovarii...

Two dogs with increased thyroxin concentrations compatible with hyperthyroidism were referred for further examinations. One dog displayed clinical signs of hyperthyroidism. Based on history, clinical examination, laboratory evaluation and scintigraphy an alimentary thyrotoxicosis was identified. It was caused by feeding a BARF diet containing thyroidal tissue in one dog and by conventional dog food in the other patient. After changing the diet the clinical signs resolved in the affected dog. A control examination revealed thyroxin concentrations within the reference range in both dogs...

We present a case of new onset psychosis in the setting of thyroid storm in a woman with no previous psychiatric history. The patient presented with ongoing suicidal ideation, a suicide attempt that was interrupted by her husband, and audio and visual hallucinations. The patient was placed on a psychiatric hold and treated for thyrotoxicosis as well as psychosis. Treatment of the thyroid hormone overload resulted in a rapid resolution of her symptoms; she was discharged in excellent condition, and she has had no repeat hallucinations or self-injury ideation or attempts since...

BACKGROUND: Ipilimumab (a monoclonal antibody against CTLA-4) and nivolumab (a humanized antibody against PD-1) target these immune checkpoint pathways and are used for treatment of melanoma and an increasing number of other cancers. However, they may cause immune-related adverse effects (IRAEs). Although many endocrinopathies are known to be IRAEs, primary hypoparathyroidism with severe hypocalcemia has never been reported. This is the first case of hypoparathyroidism as an IRAE presenting to an Emergency Department with acute hypocalcemia...

We describe the case of four patients consulting for headache and tachycardia of brutal onset. Their biological data were compatible with primary hyperthyroidism with low TSH and high T4 serum levels. Serum thyroglobulin level was low and Tc-scintigraphy showed decreased uptake with a homogenous pattern. These results allowed to conclude a thyrotoxicosis caused by thyroid hormones intake. History taking revealed consumption of beef neck meat containing all or parts of the bovine thyroid gland. Evolution was favourable with beta-blockers...

Thyroid storm or severe thyrotoxicosis results from extreme thyroid hormone elevation. Therapy includes medical management to prevent hormone production, release, recycling, and peripheral conversion while stabilizing adrenergic tone. Thyroid dysfunction is the usual cause but it can be due to excessive thyroid hormone ingestion. Therapeutic plasma exchange (TPE) has been used to rapidly remove protein-bound thyroid hormone. American Society for Apheresis guidelines make a weak recommendation to perform TPE in selected patients in the treatment of thyrotoxicosis based on low quality evidence...

TSH receptor antibody (TRAb) plays a key role in the pathogenesis of Graves' disease (GD), and its levels correlate with the clinical course. The second- and third-generation TRAb assays have >95% sensitivity and specificity for the diagnosis of GD and have improved the utility of TRAb to predict relapse. TRAb levels decline with antithyroid drug (ATD) therapy and after thyroidectomy. Its level increases for a year following radioactive iodine (RAI) therapy, with a gradual fall thereafter. TRAb level >12 IU/l at diagnosis of GD is associated with 60% risk of relapse at 2 years and 84% at 4 years...

Thyrotoxic periodic paralysis (TPP) is a rare complication of hyperthyroidism characterized by episodes of muscle weakness and hypokalemia. TPP is typically present in young Asian men, female, and non-Asian ethnic group can also be affected. TPP is a curable cause of hypokalemic periodic paralysis, can often be the first manifestation of thyrotoxicosis. Factors such as high carbohydrate diet, strenuous exercise, emotional stress, and steroid can precipitate an attack of TPP. The presence of both hypokalemia and elevated level of thyroxine (T4) and triiodothyronine (T3) are important diagnostic features during the acute episode...

Subclinical thyrotoxicosis is a condition affecting up to 10% of the population in some studies. We have reviewed literature and identified studies describing prevalences, causes and outcomes of this condition. Treatment should be considered in all subjects if this biochemical abnormality is persistent, especially in case of symptoms of thyrotoxicosis or in the presence of any complication. In particular, treatment should be offered in those subclinically thyrotoxic patients with a sustained serum TSH below 0...

BACKGROUND Cerebral venous thrombosis (CVT) is a rare but fatal complication of hyperthyroidism that is induced by the hypercoagulable state of thyrotoxicosis. Although it is frequently difficult to diagnose CVT promptly, it is important to consider it in the differential diagnosis when a hyperthyroid patient presents with atypical neurologic symptoms. CASE REPORT A 49-year-old Japanese female with unremarkable medical history came in with thyroid storm and multiple progressive ischemic stroke identified at another hospital...

OBJECTIVE: Thyroid hormone extract is used for the treatment of thyroid disorders but limited data exist on adverse events commonly noted by the physicians associated with this use. The purpose of this survey was to report adverse events observed by expert physicians managing patients treated for thyroid disease with thyroid hormones. METHODS: Members of the American Thyroid Association, The Endocrine Society and the American Association of Clinical Endocrinologists developed a survey instrument modeled on the FDA's reported adverse events for levothyroxine that would effectively assess the clinical experience of frequent prescribers of thyroid hormone...

Thyrotoxicosis may present with a variety of non specific symptoms in elderly patients. Gastrointestinal symptoms such as nausea, vomiting and abdominal discomfort can occasionally be the presenting feature of thyrotoxicosis in this age group. We describe an elderly patient in whom thyrotoxicosis was diagnosed after extensive evaluation for nausea, vomiting and anorexia. This patient was also found to have hypercalcemia. This case highlights the importance of recognizing thyrotoxicosis in older patients presenting with GI symptoms and mild hypercalcemia...
