Background: A 27-years-old women affected by recurrent pheocromocytoma/paragangliomas. We describe the evolution of disease and the surgical approach. The patient underwent a two-steps bilateral adrenalectomy for pheocromocytoma. At 15 years she underwent a left adrenalectomy. At 19 a right adrenalectomy+removal of paracaval paraganglioma were performed. After 8 years of good health she experienced again headache, tachycardia and hypertension not responsive to therapy. A diagn...

Aim of this 2-year, prospective, randomized study is to compare the effect of parathyroidectomy (PTX) vs no treatment in patients with asymptomatic primary hyperparathyroidism (PHPT), who didn’t meet the 1991 NIH criteria for surgery. The study was approved by our local Ethical Committee. The primary endpoint was the change in lumbar spine bone mineral density (BMD); secondary endpoints were BMD changes at femur and distal radius, markers of bone turnover, quality ...

Introduction: AIT develops in 15–20% of patients receiving amiodarone. Patients with persistent thyrotoxicosis or those with instable cardiac function, may be candidate for thyroidectomy; however, thyrotoxicosis and underlying cardiovascular disease may increased surgical risk.Matherials and methods: We retrospectively selected 23 AIT patients treated with a total thyroidectomy, from January 2000 to December 2010 [19 men, 4 women; mean (+SD), age 61...

Introduction: The antitumor activity of a novel cyclic amide, CLM94, with anti-VEGFR-2 and antiangiogenic activity, in primary anaplastic thyroid cancer (ATC) cells in vitro and in vivo, has been studied.Design and Methods: CLM94 was tested: i) in two human cell lines (HMVEC-d, dermal microvascular endothelial cells; 8305C, undifferentiated thyroid cancer) at 0.001–100 mcM; ii) in ATC cells at the concentrations of 10, 30, 50 mcM; iii)...

The reported prevalence of RET somatic mutations in sporadic MTC is about 40–50% and the most frequent somatic mutation is Met918Thr in exon 16. MTC harboring a somatic RET mutation have been demonstrated to have a more advanced stage at diagnosis and a worse outcome. Although RET mutations are believed to be driving events in the MTC tumorigenesis only the finding of somatic mutations in microMTC can confirm this hypothesis.Aim of the present work ...

Germline point mutations of the RET proto-oncogene are causative of hereditary MTC. Somatic mutations are described in 40% of sporadic MTCs. Although a relationship between somatic mutations and bad prognosis has been described, data are controversial.No date on the prognostic value of RET polymorphisms are available.Aim of the work was to verify if the presence of a somatic RET mutation and or a polymorphisms can influence the prognosis of MTC. This stu...

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...

Introduction: Diabetic ketoacidosis (DKA) is a feature of type 1 diabetes mellitus, but it can develop in people with type 2 diabetes (T2DM) in the presence of precipitating factors. Antipsychotics have been associated with pancreatitis without DKA or hyperglycemia or acidosis with no evidence of pancreatitis. To our knowledge, there are few reports of patients who developed pancreatitis and DKA during treatment with antipsychotis. We present a case of a patient who developed ...

Anaplastic thyroid cancer (ATC) is one of the most lethal endocrine malignancy, with a mean survival of about 6 months. Until now, the most effective therapy for ATC comprises a multimodal treatment protocol, including surgery, chemotherapy (doxorubicin and cisplatin), and hyperfractionated accelerated external beam radiotherapy, with a median patient survival of 10 months. A possible increase in the effectiveness of the treatment could be achieved testing the sensitivity of &...
