Advanced papillary thyroid carcinoma (PTC) with cutaneous metastases may cause pain, ulceration and bleeding. Electrochemotherapy (ECT) is a minimally invasive oncologic treatment of tumours located in the skin and subcutaneous tissue. The electric pulses potentiates the toxicity of a cytostatic agent entering the tumour cell. It is highly effective especially to relieve pain and improve quality of life. The adverse events are local and transient. A case of progressive metasta...

Introduction: Papillary thyroid carcinoma (PTC) and medullary thyroid carcinoma (MTC) are distinct neoplasms, associated with different histological findings. Their coexistence in the same patient is a rare event, requiring a different clinical approach.Clinical case: A 72-year-old patient with no family history of thyroid disease, underwent total thyroidectomy in February 2019, due to toxic multinodular goitre, with no evidence of postoperative complica...

Background: The most common type of thyroid cancer is the well-differentiated thyroid carcinoma (DTC) and that includes papillary (PTC) and follicular carcinoma (FTC). The PTC would represent 50–90% and the FTC over 15–30%. Within the PTC, the most frequent is the classical variant (over 80%), followed by follicular variant (10%) and the rest of variants (<10%). Furthermore, there are differences between PTC and FTC in age at diagnosis, local extension, multicent...

Introduction: The treatment of differentiated thyroid carcinoma exposes most patients to chronic supraphysiological doses of thyroid hormone which seems to have several negative effects for the patient. The goal of the present study was to assess the consequences of these doses on the bone mineral density (BMD).Patients and methods: We performed a cross-sectional study on 64 female patients followed up between 1972 and 2007. We registered the levothyroxi...

Introduction: Primary thyroid lymphoma is rare and accounts for less than 5% of all thyroid malignancies. The risk is almost 60 times higher in those with thyroiditis and is more common in females, with a ratio of 4:1. The most frequent local symptom is a rapidly enlarging thyroid gland along with the resultant obstructive symptoms. Fine needle aspiration is the initial diagnostic procedure for thyroid tissue sampling. The main differential diagnosis is anaplastic thyroid carc...

Introduction: Pregnancy is rare in patients with Cushing Disease (CD) owing to ovulatory dysfunction. When surgery is not curative, medical treatment is usually considered. Ketoconazole and mitotane, commonly used medical therapies, have questionable teratogenicity and are not often options in pregnancy. Cabergoline was found to be effective in reducing hypercortisolism in Cushing’s disease. Observational studies suggested that low dose cabergoline treatment at the time o...

Few studies have evaluated bone histomorphometry in type 2 diabetic patients (DM2) and none has established if the disease control plays a role on bone morphology and bone marrow adipocytes. The aim of this study is to present preliminary data on bone microstructure, bone formation rate and bone marrow adipocytes in premenopausal women with DM2 with different levels of glucose control. Bone biopsy, followed by tetracycline labelling, was obtained for analysis of static and dyn...

Background: IRS2-deficient (IRS2-/-) mice are considered a good model to analyze the development of diabetes as some of them present an increase in glycemia comparable to that observed in diabetes onset in humans, whereas a high proportion of these mice do not develop diabetes. Energy homeostasis regulation by the hypothalamus can be disturbed by an inflammatory environment, which predisposes an individual to the onset of diabetes. Saturated fatty acids induce hypot...

Background: Brown adipose tissue (BAT) plays a pivotal role in the regulation of energy homeostasis and thermogenesis. This tissue responds to insulin, favoring the expression of uncoupling protein-1 (UCP-1), that in turn is inhibited by insulin-desensitizing cytokines. Leptin may abolish some of the effects of fasting on these parameters through its cross-talk with insulin-related signaling targets.Objectives: We hypothesized that leptin infusion preven...

Introduction: Reports of pregnancy occurring in acromegalic patients are uncommon. Nevertheless, it appears that women are usually able to carry their pregnancy to full termCase: 39 year old woman referred to endocrinology for secondary amenorrhea and hyperprolactinemia (PRL 55.54 mg/dl). As she mentioned typical symptoms of Acromegaly, we extended the study, finding high levels of IGF1 and a pituitary macroadenoma (25×16 mm) in MRI. Presurgical tre...
