    Insights

    Autoimmune thyroiditis (AT), a common cause of hypothyroidism in older children, is rare in toddlers. Early diagnosis of AT in young children is challenging due to its infrequent presentation, often leading to delayed identification.

    Area of Science:

    • Pediatric Endocrinology
    • Immunology
    • Thyroidology

    Background:

    • Acquired autoimmune hypothyroidism, commonly diagnosed in late childhood and adolescence, is infrequently observed in children under three years old.
    • Autoimmune thyroiditis (AT) is a primary cause of acquired hypothyroidism in pediatric populations.

    Observation:

    • This report details three cases of young children presenting with symptoms suggestive of hypothyroidism, including constipation, reduced appetite, and increased sleep duration.
    • These children were diagnosed with autoimmune thyroiditis (AT), a condition rarely seen in this age group.

    Findings:

    • The study identifies AT as a potential cause of hypothyroidism in very young children, despite its rarity.
    • The presented cases underscore the diagnostic challenges associated with identifying AT in early childhood.

    Implications:

    • Early recognition of AT symptoms in infants and toddlers is crucial for timely diagnosis and management.
    • Increased awareness among healthcare providers can improve the diagnostic rate of autoimmune thyroiditis in young children.
    • Further research may elucidate specific early-onset markers for autoimmune thyroiditis in pediatric populations.

    Hypothyroidism II: Pathophysiology

    Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...

    Hyperthyroidism I: Introduction

    Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
    Graves' Disease I: Introduction01:28

    Graves' Disease I: Introduction

    Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...
    Graves Disease II: Pathophysiology01:24

    Graves Disease II: Pathophysiology

    Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...

    Hyperthyroidism II: Pathophysiology

    Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
    Type I Diabetes I: Introduction01:12

    Type I Diabetes I: Introduction

    Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...
