Background Transient non-immune hyperthyroidism in early pregnancy is hyperthyroidism diagnosed for the first time in early pregnancy, without evidence of thyroid autoimmunity or clinical findings of Grave's disease and resolved spontaneously as the pregnancy progressed. Hyperemesis gravidarum (HG) is the commonest cause with 66%-73% of women with severe HG were found to have elevated thyroid function. Materials and methods We conducted a cross sectional study to determine the prevalence of transient hyperthyroidism in patients with hyperemesis gravidarum and its relation to the severity of nausea and vomiting...

RATIONALE: Free thyroxine (fT4) and free triiodothyronine (fT3) tests are often ordered when not clinically warranted. Preventing laboratory overuse by reducing inappropriate fT4 and fT3 testing is one strategy to promote resource stewardship. OBJECTIVES: (1) To characterize the frequency of inappropriate fT4 and fT3 testing and (2) to implement a quality improvement strategy aimed at reducing the number of these tests performed. METHODS: Quality improvement tools were used to create sequential change ideas: (1) education of physicians regarding appropriate indications for ordering fT4/fT3 and (2) implementation of a hospital-wide laboratory and forced-function system with a reflex fT4...

INTRODUCTION: Anchoring bias occurs when clinicians hold on to previously known information about a patient, with failure to consider the full realm of possibilities to explain new findings. We present a case of delayed diagnosis of thyroid-stimulating-hormone-secreting pituitary adenoma (TSHoma), a rare disorder, in a military veteran whose symptoms were misconstrued as being caused from worsening of his prior diagnosis of post-traumatic stress disorder (PTSD). Anchoring bias in this case led to 2-year delay in the correct diagnosis...

BACKGROUND: Thyroid hormone (TH) is known to enhance arrhythmogenicity, and high-normal thyroid function is related with an increased recurrence of atrial fibrillation (AF) after catheter ablation. However, the impact of thyroid hormone replacement (THR) on AF ablation is not well known. METHODS: This study evaluated 1163 consecutive paroxysmal AF patients [160 (14%) on THR and 1003 (86%) without THR] undergoing their first catheter ablation. A total of 146 patients on THR and 146 controls were generated by propensity matching, based on calculated risk factor scores, using a logistic model (age, sex, body mass index, and left atrium size)...

Thyroid hormones are bound to three major serum transport proteins, thyroxin-binding globulin (TBG), transthyretin (TTR) and human serum albumin (HSA). TBG has the strongest affinity for thyroid hormones, TTR is also found in the cerebrospinal fluid and HSA is the most abundant protein in plasma. Combination defects of either a high affinity TTR or HSA variant do not compensate TBG deficiency, underscoring the dominant role of TBG among the thyroid hormone transport proteins. On the other hand, coexistence of raised affinity TTR and HSA variants causes an augmented hyperthyroxinemia...
