A 38-year-old woman with chronic autoimmune thyroiditis and hypothyroidism treated with levothyroxine (125 μg/day) was referred to our outpatient clinic with a history of sudden increase of goiter, weakness, dysphagia, dyspnea and suffocating sensation. Physical examination showed an enlarged, stony thyroid gland (three times of normal), without palpable cervical lymph nodes. Biochemical evaluation showed the following abnormalities: TSH 6.0 μU/ml (0.4–4.3), fre...

Aim of the study was to evaluate whether clinical parameters and echographic patterns may be predictive of malignancy in thyroid nodules with a cytological diagnosis of follicular (FOL) and H?rthle cell (HC) neoplasia. The study included 495 patients (388 F: mean age 45±14 yr; 107 M: mean age 46±14 yr) with FOL (n=418) and CH (n=77) nodules, ‘cold’ at scintiscan and undergone to thyroidectomy. Clinical parameters considered were: sex, age, goi...

Aim of the study was to establish the diagnostic value of nuclear atypia thyroid nodules with cytological diagnosis of follicular (FOL) and Hv¨rthle cell (HC) neoplasia. 1039/23.313 fine needle aspiration (FNA) performed in January 2002 June 2005 in the Department of Endocrinology, University of Pisa had cytological diagnosis of FOL e CH. FNA was performed under echo guidance, using 23 gauge needle attached to 10 mL syringe. The material was air-dryed and stained with Pap...

About 10–15% of FNA cytologies are nondiagnostic, because of inadequate material or indeterminate (i.e. follicular neoplasms). Aim of this study was to analyse the practical usefulness of the analysis of BRAF mutations and RET/PTC rearrangements, known to be associated to papillary thyroid carcinoma (PTC), in FNA-material.We analysed 100 thyroid nodules with a nondiagnostic cytology: 75 follicular nodules and 25 cases with inadequate material. Fifte...

Familial isolated primary hyperparathyroidism (FIPH) can result either from incomplete expression of a syndromic form of familial primary hyperparathyroidism [multiple endocrine neoplasia types 1 (MEN 1), hyperparathyroidism-jaw tumor syndrome (HPT-JT), or familial hypocalciuric hypercalcemia (FHH)] or still unrecognized causes.We investigated the involvement of MEN1, HRPT2 and CASR genes by direct sequencing of germline DNA in seven...
