Introduction: Chronic lymphocytic thyroiditis (LT) is a very common condition, and its coexistence with papillary thyroid carcinoma has often been reported. Analytical and echographic challenges must be kept in mind in the follow-up of patients with both these disorders.Case report:: We present the case of a woman with a history of multinodular goitre who underwent left thyroidectomy and isthmectomy at the age of 43, with the histopathological finding of...

Introduction: The TNM staging system for well differentiated thyroid cancer (WDTC) considers tumours over 4 cm diameter limited to the thyroid or tumours with minimal extra-thyroid extension to be classified as pT3. This stage can be considered quite heterogeneous, as different clinical and pathologic characteristics seem to have distinct prognosis value.Aims: To determine prognostic factors amongst clinical, laboratorial, histologic and radiologic chara...

Introduction: Adrenocortical carcinoma is a rare endocrine disease characterized by an aggressive behaviour with a poor prognosis. Clinical experience, even with a little number of patients, has enhanced knowledge about this malignancy, in most cases challenging.Objective: Characterization of patients with adrenocortical carcinoma followed at the endocrine department of a hospital centre, between 1991 and 2019.Methods: Retrospectiv...

Background: Therapy with levothyroxine (L-T4) is essential in hypothyroidism treatment. The marked elevation of thyrotropin (TSH) in patients treated with appropriate doses of L-T4 is rare and can result from malabsorption, drug interaction or poor adherence. The non-adherence, omitted by the patient, is called pseudo malabsorption.Clinical report: ACCS, female, 30 years old, hospitalized for persistent...

Background: Nonfunctioning pituitary adenomas are commonly diagnosed as large tumors. Most are detected incidentally during imaging studies. The aim of this study was to evaluate clinical presentation, characteristics and outcome of nonfunctioning pituitary macroadenomas incidentally (NFPMI) discovered.Methods: Twenty-seven patients (mean age 58.9 years, 45–82; 18 males:9 females) with NFPMI were studied. They represent 13.1% of NFPM followed in our...

Introduction: About 20% of fine needle aspiration biopsy of thyroid (FNA) with result of follicular tumour (FT) is malignant. Several factors have been suggested as indicators of malignancy.Objectives: To determine predictive factors of malignancy in FNA with result of FT.Methods: We evaluated retrospectively 140 clinical files of patients with cytology (ultrasound-guided or palpation) of FT. Presence of relationship between malign...

Aims: End stage renal disease is associated with disorders of calcium and phosphate metabolism that favor the loss of bone mass.Kidney transplant may alter this unbalance restoring bone mass. Nevertheless, recent studies showed that 48 months after transplant, the loss of bone mass still is superior to general population. Post-transplant corticosteroid therapy is considered the main responsible for the loss of bone mass.The authors...

Familial hypocalciuria hypercalcemia (FHH) is an autossomal dominant condition caused by mutations in the calcium sensing receptor gene. It is characterized by moderate hypercalcemia, with normal or slightly elevated PTH levels and hypocalciuria secondary to the increased calcium reabsorption at the distal tubule level.We present a case report of a 16 year old patient, who was referred to our department at the age of 14 because of obesity (BMI: 36.9 K/m<...

Pituitary adenomas are present in ∼25% of autopsy samples, and recent studies have also suggested that clinically important pituitary adenomas are some 5 times more common than previously recognised. Acromegaly is almost always due to a sporadic growth-hormone secreting pituitary adenoma, but familial acromegaly has been reported occasionally. Linkage and loss of heterozygosity studies have shown that it is caused by a tumour suppressor gene located at 11q13; very recent...

GH consists of various molecular isoforms. Most abundant is 22 kDa-GH (80–90% of total GH), followed by 20 kDa-GH (5–15% of total GH). The biological significance of 20 kDa-GH remains unclear, but its effects appear comparable to those of 22 kDa-GH. Acromegaly is characterized by chronic GH excess. Data on GH isoforms in acromegaly are scarce, but an increased 20 kDa-/22 kDa-GH-ratio (20k-ratio) has been described. Our aims were to compare the 20k-ratio in a larger c...
