Background: We report two cases of rheumatism associated with hyperthyroidism. In both cases, arthralgia totally regressed after thyroid treatment.
Case Reports: Two 79-year-old and 59-year-old women developed manifestations of polymyalgia rheumatica and psoriasis arthritis respectively. Corticosteroid therapy was ineffective and followed by manifestations of hyperthyroidism. The first patient was treated with carbimazole and the second with thyroidectomy. Once the hyperthyroidism was controlled, both patients experienced a dramatically rapid cure of their arthralgias.
Discussion: Scalpulo-humeral periarthritis is the main articular complication of hyperthyroidism. True manifestations of "thyrotoxicosis rheumatism" are unusual and may be linked with a direct toxicity of the thyroid hormones on joint cartilage or with an autoimmune manifestation of hyperthyroidism.

Antithyroid drugs can cause neutropenia or agranulocytosis, rarely pancytopenia in hyperthyroidism therapy. The treatment is difficult and lethality is high when granulocytopenia or pancytopenia combined with hyperthyroidism crisis. First Affiliated Hospital of Army Medical University treated a patient who had pancytopenia caused by methimazole with systemic lupus erythematosus, secondary hyperthyroidism crisis and agranulocytosis.

Thyroid eye disease (TED) is the most consequential extrathyroidal manifestation or complication of Graves' disease (GD). Treatment of hyperthyroidism in GD complicated by TED is challenging. Antithyroid drugs (ATDs) and thyroidectomy do not change the natural course of TED, while radioactive iodine (RAI) is associated with a small but well-documented risk of TED de novo occurrence or its progression/worsening.

Background: Overt hyperthyroidism and hypothyroidism are regarded as possible causes of reversible dementia. Evidence on the risk of dementia associated with subclinical thyroid dysfunctions is limited and barely existent in the very old, while findings are conflicting.
Objective: To cross-sectionally and longitudinally investigate the association of subclinical-hyperthyroidism and subclinical-hypothyroidism with dementia in a prospective population-based study of 80-years or older residents in Varese province, Italy (Monzino 80-plus Study).

Objectives: Total thyroxine (TT4) evaluation is the most commonly used first-line test for the diagnosis and monitoring of cats with hyperthyroidism. Vcheck T4 is a point-of-care immunoassay that measures TT4 using a Vcheck V200 analyser. This study aimed to evaluate the analytic performance of the Vcheck T4 assay in feline sera and the agreement in the classification of normal, high and low TT4 concentrations of Vcheck T4 with those measured by an enzyme immunoassay (EIA).

Mendelian randomization (MR) was employed to investigate the causal relationships between immune cell phenotypes, hyperthyroidism (HD), and potential metabolic mediators. In this study, we acquired 731 immune cell phenotypes from genome-wide association studies (GWAS) (n = 18,622), HD data from the research by Handan Melike Dönertaş et al. (3,731 cases, 480,867 controls), and aggregated statistics of 1,400 blood metabolites from UK Biobank (n = 115,078).
