A hyalinizing trabecular tumor (HTT) of the thyroid gland is a very rare type of tumor. It is usually diagnosed incidentally during the examination for thyroid gland diseases that need thyroidectomy. Here we report a case of HTT in a 60-year-old male patient who presented with anterior neck swelling and underwent total thyroidectomy for a Bethesda category V nodule. The final histologic diagnosis of the left lobe was consistent with a hyalinized trabecular adenoma of the thyroid gland, or paraganglioma-like adenoma. We discuss the clinical picture and diagnostic approach, including the role of fine needle aspiration biopsy, and the pathologic features of HTT, with particular reference to the possible differential diagnosis.

BACKGROUND The thyroglossal duct cyst, which develops from the midline migratory tract between the foramen cecum and the anatomic location of the thyroid, is the most prevalent congenital abnormality of the neck, accounting for about 70% of all cervical neck masses in children and 7% in adults. Only up to 1% of these abnormalities contain malignant thyroid tissue, with 90% of those cases being papillary thyroid carcinoma. Thyroglossal duct cyst is rarely linked to carcinoma.

Background The thyroid gland is the most susceptible organ to radiation during the exposure of teeth because the thyroid area appears to be within the primary beam, and the dose levels are relatively high even after using collimation. This study aims to develop an eco-friendly thyroid shield by reusing lead foils from intra-oral periapical radiographic films and evaluate its effectiveness in intraoral radiography. Methods A total of 16 patients undergoing endodontic procedures who gave written consent to participate in the study were included and divided into four categories: anterior, canine, premolar, and molar.

The effect of cardiac catheterization on thyroid functions in infants with congenital heart diseases: a prospective observational study.

Eur J Pediatr

January 2025

Pediatric Endocrinology and Diabetes Unit, Department of Pediatrics, Mansoura Faculty of Medicine, Mansoura University Children's Hospital, Mansoura University, Gomhoria Street, Mansoura, 35516, Dakhlia, Egypt.

Unlabelled: This study aims to determine the incidence, clinical course, and risk factors of hypothyroidism following cardiac catheter (CC) in infants with congenital heart diseases (CHD). This prospective study involved 115 patients with CHD, all aged 3 years or younger, who underwent CC, as well as 100 healthy age- and sex-matched controls. Baseline thyroid function tests (TFTs) were conducted for both the patients and controls.

Subacute thyroiditis - Is it really linked to viral infection? Retrospective hospital patient registry study.

J Clin Endocrinol Metab

January 2025

Institute of Virology, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany.

Objective: Subacute thyroiditis (SAT) is a painful inflammatory disorder of the thyroid gland, which - after a phase of thyrotoxicosis - leads to transient, or less frequently permanent hypothyroidism. Apart from a strong association with specific HLA alleles, the causes are uncertain. Viral disease has been hypothesised as a trigger, with Enteroviruses, namely Echoviruses and Coxsackieviruses, showing a seasonal distribution that coincides with the incidence of SAT.

Objective: To assess the impact of parathyroid gland autotransplantation on the restoration of parathyroid function in patients who are hypoparathyroid after thyroidectomy.

Background Data: Hypoparathyroidism post-thyroidectomy arises when all parathyroid glands are devascularized or injured. Autotransplantation of compromised parathyroids aims to preserve their function and prevent permanent hypoparathyroidism.
