Autoimmune gastritis is an additional factor affecting l-T(4) requirement in patients with autoimmune thyroiditis. Serum PCA measurement should be considered in patients with an unexplained high requirement of l-T(4).
AMH levels are elevated in PCOS patients regardless of the body weight. Bariatric surgery is effective in the normalization of AMH levels (a possible indirect marker of better fertility) only in obese patients with PCOS.
These results confirm that obese subjects have shorter telomeres compared to non-obese subjects, but RTL is not influenced by the presence of metabolic syndrome. RTL shows an additional attrition during the immediate post-operative period, probably due to a catabolic state.
Clinicians should be aware about the risk of hypophysitis during treatment with immune check-point inhibitors and the necessity of investigating pituitary function during therapy. Pituitary magnetic resonance imaging does not seem pivotal for a definite diagnosis if not performed at the onset of disease.
Our study demonstrates that ghrelin secretion is negatively affected by autoimmune gastritis, and its serum level represents the most sensitive and specific noninvasive marker for selecting patients at high risk for ABG.
We investigated whether serum thyroglobulin determination before surgery for differentiated thyroid carcinoma may have any prognostic value with regard to tumour extension and disease outcome in a retrospective series of 71 patients with papillary thyroid cancer. Presurgical serum thyroglobulin levels were correlated with the size of the primary tumoral nodule (p = 0.006) and of the whole thyroid (p = 0.02). The same correlation was found in a control group of patients with benign thyroid nodules, confirming that presurgical serum thyroglobulin cannot be used for the differential diagnosis of thyroid carcinoma. Presurgical serum thyroglobulin levels did not differ among patients with tumor limited to thyroid gland or extending to cervical lymph nodes or invading outside the thyroid capsule or metastasising to distant size. In addition presurgical serum thyroglobulin levels were not correlated with the disease outcome after a mean follow-up of 9 years: no difference was found among patients in complete remission or with persistent disease or dead from thyroid cancer. In conclusion, this study failed to show any prognostic value of presurgical serum thyroglobulin determination that consequently should not be measured.
Management of thyroid nodules is one of the most controversial issues in thyroidology. Different approaches derive from geographical variation in presentation, inadequate or incomplete clinical diagnosis, lack of prospective controlled studies and, frequently, the different cultural backgrounds of physicians. This review aims to offer a practical approach to the management of nodular thyroid disorders, considering the way in which the pathophysiology of the disease provides clues to the correct clinical diagnosis and therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
