Bisphenol A Induces DNA Damage and Differential Cytotoxicity in Thyroid Cells: High‐Dose Effects Challenge Regulatory Thresholds

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), a ubiquitous environmental endocrine disruptor, has been implicated in carcinogenesis; however, its effects on thyroid cells remain unclear. This study investigated BPA‐induced cytotoxicity and genotoxicity in thyroid cell lines, including normal follicular (Nthy‐ori 3‐1), papillary carcinoma (TPC‐1 and BCPAP) and anaplastic

Assessment of Thyroid Uptake Ratio Values in a Normal Population. Establishment of Normal Reference Values for 99mTc‐Pertechnetate Thyroid Uptake in an Australian Population

Journal of Medical Radiation Sciences, EarlyView.
An Australian first, this study examined normal reference ranges for 99mTc‐pertechnetate thyroid uptake. Through a retrospective and prospective analysis, this study found a new reference range of 0.4%–2.4%. The findings suggest that locally derived reference values may differ from historical data and highlight the importance of region‐specific ...

The single thyroid nodule

Journal of British Surgery, 1972
Abstract Between November, 1966, and March, 1970, 2736 patients with single thyroid nodules were investigated at the Alexandra Hospital. Females were more frequently affected than males, with a ratio of females to males of about 7:1. The right lobe was one and a half times more frequently involved than the left.

Mapping the Landscape of Over‐Scanning in CT Imaging: A Scoping Review

Journal of Medical Radiation Sciences, EarlyView.
Over‐scanning in CT is highly prevalent and contributes to unnecessary radiation exposure, with notable impact on radiosensitive organs. Standardised protocols and AI‐assisted planning show strong potential to optimise scan range and reduce excess dose.

Synchronous Presentation of Type 2 Marine–Lenhart Syndrome and Differentiated Thyroid Carcinoma Manifesting as Thyroid Storm

Case Reports in Endocrinology
Marine–Lenhart syndrome (MLS) is a rare condition characterized by the coexistence of hyperfunctioning thyroid nodules and Graves’ disease (GD). The prevalence of thyroid nodules and thyroid cancer is higher in patients with GD.

Clinical and genetic features of pediatric hereditary polyposis syndromes in Israel: A nationwide multicenter cohort

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Hereditary polyposis syndromes in children are rare, heterogeneous disorders associated with significant morbidity and long‐term risk of malignancy. Current data on their presentation, management, and outcomes in pediatric populations remain limited.

A preterm neonate with infantile liver failure syndrome 1 due to leucyl‐tRNA synthetase 1 gene (LARS1) mutations with a histopathologic phenotype of neonatal hemochromatosis

JPGN Reports, EarlyView.
Abstract We report a case of a premature, growth‐restricted female infant with feeding intolerance and coagulopathy, treated initially for sepsis, who progressed to neonatal acute liver failure and end‐stage hepatic encephalopathy after a prolonged hospitalization with extensive diagnostic evaluation, and was found by autopsy to have histopathologic ...

Isolated Thyroid Metastasis of Malignant Melanoma with Unknown Primary Origin

Endocrinology Research and Practice, 2008
Clinically significant metastases to the thyroid gland are very rare; however, they can present as the initial malignancy. We report the case of a 70-year-old woman referred to our Endocrinology outpatient clinic for a thyroid nodule, which was in fact ...

Optimized Coherence Masking Improves Ultrasound Imaging of Kidney Cysts

Journal of Ultrasound in Medicine, EarlyView.
Objectives Renal cystic lesions are exceedingly common and typically benign, though accurate diagnostic techniques are required to recognize the subset of malignant lesions that require timely intervention. Ultrasound (US) is the preferred first line test for renal cyst evaluation because it is safe, widely accessible, and low cost. US imaging, however,

Thyroid nodules in pregnancy.

Thyroid : official journal of the American Thyroid Association, 1992
Thyroid nodules are common in pregnant women. Most of them are benign. Toxic autonomous nodules may be seen infrequently, and the diagnosis is supported by elevated free thyroid hormone levels and undetectable levels of TSH. The most common and most important problem is the diagnosis of thyroid cancer. FNB is the most reliable diagnostic tool.
