Introduction: Medullary thyroid carcinoma (MTC) accounts for 1-5% of all thyroid cancers. It is a neuroendocrine tumor arising from the calcitonin-secreting parafollicular cells of the thyroid. In rare cases, the neoplastic cells additionally secrete other substances, such as histamine, serotonin, ACTH, CRF etc, leading to paraneoplastic syndromes.Case report: An 80 year old male presented to our Department with an already diagnosed metastatic MTC. Three...

Objectives: Assess the dose of levothyroxine in relation to TSH and FT4 at diagnosis of AHT in children with SH and OH.Methods: Two hundred one children (155 girls) with AHT were devided according to TSH and FT4 levels at diagnosis of hypothyroidism [SH-FT4 >1.0 ng/dl: Group 1: TSH: 5–7.5 mU/l, Group 2: TSH: >7.5 mU/l, OH: Group 3: TSH>7.5 mU/l and FT4 ≤1.0 ng/dl]. Mean L-T4 dose was reported in μg/Kg per day at diagnosis and ...

Background: Increased fibrinogen levels have been reported in prepubertal children and adolescents with growth hormone deficiency (GHD), which were reduced after rhGH treatment. rhGH treatment has also been shown to exert a beneficial effect on the amount of aPAI-1 in children with GHD.Aim: Of the study was to evaluate whether prepubertal GH deficient (GHD) children showed any impairment in coagulation- and fibrinolysis-related parameters and the effect ...

Introduction: Although the protective effects of 1,25(OH)2D3 on the early stages of atheromatosis process have been investigated, data on its influence on factors implicated in plaque vulnerability are limited. During these stages metalloproteinases MMP-2, MMP-9, their inhibitors TIMP-1,TIMP-2, the RANKL-RANK-OPG system and MCP-1 play a critical role. We aimed to investigate the effect of vitamin D on the expression of the above factors on endothelial cel...

Aim: To evaluate whether anthropometric indices and acanthosis nigricans can be useful markers for early detection of Insulin Resistance and Metabolic Syndrome (MetS) in overweight and obese children.Methods: Data from 510 prepubertal children (40% boys), 12.9% overweight and 87.1% obese with mean age 9.7±2.5 years were analyzed. Logistic regression analysis was used to investigate which factors were associated with HOMA-IR >3 and metabolic synd...

Introduction: Diagnostic and post-therapy radioiodine whole body scan (WBS) is used in the follow-up of differentiated thyroid carcinoma (DTC) for the detection of local recurrence or remote metastasis. We report a case of false-positive uptake of radioiodine WBS.Case report: A 37-year-old female patient underwent subtotal thyroidectomy for multinodular goitre and histology revealed multifocal papillary thyroid carcinoma, of follicular type with three fo...

Background: Many patients with differentiated thyroid cancer (DTC) are treated with radiodine (I-131) after thyroidectomy, while they are hypothyroid and all are submitted to withdrawal of LT4 periodically for the evaluation of their disease. Among the tests used for follow-up is serum thyroglobulin (Tg) as a tumor marker, and occasionally, total body scan with I-131. Maximal sensitivity of the aforementioned tests is established in the hypothyroid state, under elevated thyrot...

Introduction: Fine needle aspiration biopsy (FNAB) is the initial investigation of choice for thyroid nodules.Methods: A total of 563 patients (106 males/457 females) underwent FNAB for the same number of thyroid nodules. Their mean age was 56.1±14.1 years. We correlated the demographic profile (age and gender) and sonographic features of these nodules with the FNAB outcome. The Bethesda system for reporting thyroid cytopathology was used.<p cla...

Background: Primary thyroid lymphoma (PTL) is a rare thyroid malignancy. Nevertheless, it frequently presents diagnostic and therapeutic challenges. We describe two patients with PTL with different clinical presentation/clinical picture and outcome.Patients and methods: Two female patients underwent total thyroidectomy, the first, a 67-year-old female patient, because of nodular goitre and the second, a 79-year-old female patient, because of a large, pai...
