OBJECTIVE To investigate a cohort of pediatric patients with thyroid nodules, defining histotype frequency and differences between subjects with hyperthyroidism and euthyroidism and benign and malignant nodules. DESIGN Retrospective cohort. SETTING Consecutive cases from 9 Italian pediatric endocrinology centers for the last 10 years. Patients One hundred twenty pediatric patients with thyr...
PURPOSE The management criterion of thyroid nodules is to evaluate the risk of malignancy, based on cytological examinations. Ultrasound-guided fine-needle aspiration biopsy (US-FNAB) has a highly diagnostic value for thyroid nodules. The aim of this study was to compare the efficacy of US-FNAB for thyroid nodules with different sizes. MATERIAL AND METHODS From August 2013 to November 2013, 3...
US-guided fine needle aspiration cytology is currently the best diagnostic tool for thyroid nodules. The aim of this research was to make a detailed and objective determination of the morphological characteristics of cells in cytological smears in an attempt to distinguish benign from malignant follicular tumors. The research included 62 patients with cytologically diagnosed follicular or oncoc...
The enlargement of the thyroid is, in general, benign in origin and due to nodular goitre. Follicular cellular proliferation of thyroid nodules has been increasingly observed recently. With fine needle aspiration biopsy (FNAB) this is classified as a follicular tumour. These lesions present various patterns of vascularisation in ultrasound examination. The aim of the study was to establish the ...
Nonsteroidal biochemical markers of oocyte maturity could presumably aid in oocyte selection and in the timing of insemination for in vitro fertilization. We assessed the usefulness of six potential markers found in follicular fluid. We used kinetic immunonephelometry to measure concentrations of alpha 1-antitrypsin, alpha 2-macroglobulin, antithrombin III, ceruloplasmin, fibrinogen, and plasmi...
Background. The Japan Thyroid Association recently published guidelines for clinical practice for the management of thyroid nodules, which include a diagnostic system for reporting thyroid fine needle aspiration cytology. It is characterized by the subclassification of follicular neoplasms, which is different from other internationally accepted reporting systems. Materials and Methods. This stu...
Thyroid cancer harbours in about 5% of thyroid nodules. The majority of them are well-differentiated cancers originating from the follicular epithelium, and are subdivided into papillary and follicular carcinomas. Undifferentiated carcinomas and medullary thyroid carcinomas arising from C cells are less common.Although most thyroid nodules are benign, distinguishing thyroid cancer from benign l...
