The relationship between body mass index and thyroid cancer pathology features and outcomes: a clinicopathological cohort study.

Background: Obesity has been implicated as a predisposing and disease-modifying factor in cancer. Epidemiological studies suggest that obesity is associated with an increased risk of thyroid cancer; however, the relationships between obesity and thyroid cancer stage or behavior are uncertain. We hypothesized that a higher body mass index (BMI) would be associated with aggressive thyroid cancer features and a higher incidence of persistent/recurrent disease.

Acute bacterial suppurative thyroiditis: a clinical review and expert opinion.

Background: Acute suppurative thyroiditis (AST) resulting from a bacterial infection is an infrequent but potentially life-threatening endocrine emergency. Traditional management of this disease has been surgery in conjunction with targeted antibiotic therapy. Recent nonrandomized reports of small series have demonstrated good outcomes using less invasive approaches.

Dysregulation of the phosphatidylinositol 3-kinase pathway in thyroid neoplasia.

The phosphatidylinositol 3-kinase (PI3K) signaling pathway is an important regulator of many cellular events, including apoptosis, proliferation, and motility. Enhanced activation of this pathway can occur through several mechanisms, such as inactivation of its negative regulator, phosphatase and tensin homolog deleted on chromosome ten (PTEN), and activating mutations and gene amplification of the gene encoding the catalytic subunit of PI3K (PIK3CA). These genetic abnormalities have been particularly associated with follicular thyroid neoplasia and anaplastic thyroid cancer, suggesting an important role for PI3K signaling in these disorders.
