Background: Primary thyroid diffuse large B cell lymphoma (DLBCL) is a rare type of extranodal lymphoma; optimal treatment methods and the key prognostic factors have not been established. Methods: The clinical data of 58 patients with primary thyroid DLBCL from January 2007 to December 2017 were collected. The Kaplan-Meier method and log-rank tests were used for the survival analysis. Cox regression analysis was performed to evaluate the prognostic factors. Results: The follow-up time was 6-120 months; 5-year overall survival (OS) and progression-free survival (PFS) were 73 and 61%, respectively...

Background: In adults, a significant impact of thyroid dysfunction and autoimmunity on health-related quality of life (HRQoL) and mental health is described. However, studies in children and adolescents are sparse, underpowered, and findings are ambiguous. Methods: Data from 759 German children and adolescents affected by thyroid disease [subclinical hypothyroidism: 331; subclinical hyperthyroidism: 276; overt hypothyroidism: 20; overt hyperthyroidism: 28; Hashimoto's thyroiditis (HT): 68; thyroid-peroxidase antibody (TPO)-AB positivity without apparent thyroid dysfunction: 61] and 7,293 healthy controls from a nationwide cross-sectional study ("The German Health Interview and Examination Survey for Children and Adolescents") were available...

This article discusses the role of imaging of the thyroid gland in children, highlighting pearls and pitfalls. In the pediatric age group, thyroid imaging is mainly performed for the evaluation of congenital hypothyroidism, diffuse thyroid enlargement, and thyroid nodules. Permanent congenital hypothyroidism is most often caused by thyroid dysgenesis. Diffuse thyroid enlargement is mainly seen in teenage girls, and most often caused by Hashimoto disease, nodular hyperplasia, Graves disease, or diffuse papillary carcinoma...

INTRODUCTION: Primary thyroid lymphomas are rare. They constitute only 2% of all thyroid malignancies. It is important to distinguish it from other tumors of the thyroid due to the marked difference in approach to management. Preoperative diagnostic confirmation is ideal to allow for appropriate therapeutic management, which consists of chemotherapy with or without radiotherapy and to avoid unnecessary surgery. In a select group of patients, surgery may be of benefit to relieve obstructive symptoms and establish diagnosis...

Autoimmune Thyroid diseases, such as Hashimoto's thyroiditis, is characterized by lymphocytic infiltration and altered function of the thyroid. During inflammation, it has been reported a decreased expression in Tg and NIS, accompanied by an increase in HA production that accumulates in the gland. HA fragments produced in different pathological states can modulate gene expression in a variety of cell types and may prime inflammatory response by interacting with the TLR-2, TLR-4 and CD44 that, in turn, induce NF-kB activation finally responsible of inflammatory mediator transcription, such as IL-1β, TNF-α and IL-6...

Autoimmune thyroid diseases (AITDs) which include Graves' disease (GD) and Hashimoto's thyroiditis (HT) as well as type 1 diabetes (T1D) are common autoimmune disorders in children. Many genes are involved in the modulation of the immune system and their polymorphisms might predispose to autoimmune diseases development. According to the literature genes encoding IL2RA (alpha subunit of Interleukin 2 receptor), IFIH1 (Interferon induced with helicase C domain 1) and CTLA-4 (cytotoxic T cell antigen 4) might be associated with autoimmune diseases pathogenesis...

Autoimmune thyroid disease (ATD) is the most frequent cause of acquired thyroid dysfunction, most commonly presenting either as Hashimoto's thyroiditis or Graves' Disease. Hashimoto's thyroiditis is characterized by the presence of thyroid-specific autoantibodies, more commonly anti-thyroperoxidase antibodies in the serum and the typical inhomogeneous echostructure of the thyroid on a thyroid ultrasound examination. Hashimoto's thyroiditis can for a long time be accompanied by normal thyroid function and hypothyroidism can only progressively be established...

INTRODUCTION: Oxidative stress has been proposed as one of the factors concurring in the pathophysiology of autoimmune thyroid diseases. Reactive oxygen species are the main expression of oxidative stress in biological systems, and their production can overcome antioxidant defenses ultimately leading to cell damage, apoptosis, and death. The present review was aimed at describing the state of the art of the relationships between oxidative stress and autoimmune thyroiditis. The most used biomarkers of oxidative stress and their correlation with thyroid function are reported...

Erythema annulare centrifugum (EAC) is an unusual skin condition appearing as recurrent erythematous annular eruptions associated with autoimmune disorders, infections, and various neoplastic conditions. We present a very rarely reported association of EAC with Hashimoto thyroiditis (HT) in a young male. A 26-year-old male recently diagnosed as case of HT presented in the dermatology clinic with nine-month history of non-itchy persistent annular lesions on the body. The morphology and biopsy of lesions confirmed the diagnosis of EAC...

While liver enzyme changes are frequently reported in hyperthyroidism, liver dysfunction itself can lead to alterations in thyroid hormone metabolism. However, the exact relationship between hyperthyroidism and liver dysfunction is unclear. We report an 11-year-old boy presenting with acute hepatitis of unknown etiology, who was incidentally found to have asymptomatic biochemical hyperthyroidism. Despite significant total and free T4 elevation, clinical evidence of thyrotoxicosis was absent. Thyroid I-123 uptake was also reduced...

Levothyroxine (L-T4) is among the most widely prescribed medications in the world, and it is considered by the World Health Organization an essential medicine for basic health care. Replacement therapy has always been considered straightforward although different factors may interfere with intestinal absorption of L-T4, including food, dietary fibre, coffee, drugs, and gastrointestinal diseases. For these reasons, current guidelines recommend that L-T4 should be taken in a fasting state because its absorption is maximised when it is taken on an empty stomach, reflecting the importance of gastric acidity in the absorption process...

Background: Although the American Thyroid Association (ATA) guidelines indicate that central lymph nodes posterior to the right recurrent laryngeal nerve (LN-prRLN) should be routinely dissected, pr-RLN dissection is often neglected due to the high risk of injury to the recurrent laryngeal nerve (RLN). The purpose of this study was to investigate the risk factors associated with LN-prRLN metastasis in patients with papillary thyroid carcinoma (PTC) by preoperative examination and the indications for LN-prRLN dissection...

OBJECTIVE: To determine the circulatory miRNA expression levels in patients with Hashimoto thyroiditis (HT) at the time of diagnosis and follow-up period compared with healthy controls. METHODS: We collected blood samples from 34 patients with HT (4 males and 30 females) at the time of first diagnosis (Group P) and euthyroid period (Group E). Thirty-three healthy controls (Group H) blood samples were also included in the study. Expression levels of five different circulating miRNAs (miR-22, miR-141, miR-155, miR-375, miR-451) were evaluated using real-time polymerase chain reaction...

BACKGROUND: Parenchymal fibrosis, which develops in the case of thyroiditis, makes thyroidectomy difficult and increases complication rates. Similar concerns exist within minimally invasive thyroid surgery. This study aimed to evaluate the outcomes of the transoral endoscopic thyroidectomy vestibular approach (TOETVA) procedure in patients with thyroiditis. MATERIALS AND METHODS: The data of 56 patients who underwent TOETVA between February 2018 and March 2020 were analyzed retrospectively...

OBJECTIVE: To describe the frequency of polyautoimmunity and multiple autoimmune syndrome in patients with rheumatoid arthritis (RA) and patients with systemic lupus erythematosus (SLE). PATIENTS AND METHODS: This was a cross-sectional observational study of patients with RA, SLE, and controls without autoimmune rheumatic disease. Cases were those with RA according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria and SLE according to the 2019 American College of Rheumatology/European League Against Rheumatism criteria, consecutively recruited in a rheumatology clinic...

Hashimoto's thyroiditis (HT) and Graves' disease (GD) are autoimmune thyroid diseases (AITD) that cause hypothyroidism and hyperthyroidism, respectively. The vitamin D receptor (VDR) and the Fey receptor IIA (FcγRIIA), are implicated in the etiology of AITD. This study was conducted to examine the implication of VDR rs7975232 and FCGR2A rs 1801274 variations in the susceptibility and the prognosis of AITD in the Tunisian population. The rs7975232 and rs1801274 (R131H) polymorphisms were analyzed in 162 controls and 162 AITD patients (106 HT and 56 GD) by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and amplification of refractory mutation system-PCR (ARMS-PCR), respectively...

Hashimoto's encephalopathy (HE) is a rare autoimmune disorder. It associates encephalopathy with autoimmune thyroiditis, presenting abnormal elevations of thyroid antibodies. It is more common in females. It can present with various symptoms, including seizures, myoclonus, psychosis, hallucinations, and mood disturbances. Hypochondriacal delusion is an unusual clinical presentation of this disorder. The authors report a case of HE in a male patient whose clinical presentation was dominated by hypochondriacal delusion...

Vitamin D is a steroid hormone traditionally connected to phosphocalcium metabolism. The discovery of pleiotropic expression of its receptor and of the enzymes involved in its metabolism has led to the exploration of the other roles of this vitamin. The influence of vitamin D on autoimmune disease-namely, on autoimmune thyroid disease-has been widely studied. Most of the existing data support a relationship between vitamin D deficiency and a greater tendency for development and/or higher titers of antibodies linked to Hashimoto's thyroiditis, Graves' disease, and/or postpartum thyroiditis...

BACKGROUND: Hashimoto's disease has reportedly been associated with stroke; however, cerebrovascular morphology and clinical course remain poorly documented. The present study aimed to determine the angiographic features and clinical outcomes of intracranial arterial stenosis (IAS) associated with Hashimoto's disease in a retrospective cohort. METHODS: Overall, 107 adult patients with IAS were screened for anti-thyroid antibodies; of these, 26 patients tested positive...
