Hypothyroidism is usually treated with levothyroxine (L-T4), that is present in different formulation. We aim to assess if hypothyroid patients have a better control of thyroid-stimulating hormone (TSH) levels by following a L-T4 therapy in a liquid formulation, with respect to the tablet formulation. We enrolled seven hundred hypothyroid patients treated with liquid L-T4, and three hundred and fifty hypothyroid subjects receiving tablet L-T4 (both groups were matched by age a...

Tablet levothyroxine (L-T4) is the common treatment for hypothyroidism. We aim to investigate the efficacy of L-T4 in liquid formulation in patients recently subjected to total thyroidectomy (without malabsorption or drug interference), with respect to L-T4 tablets. Eighty patients were treated with L-T4 in tablets, whereas one hundred and sixty received liquid L-T4 at the same dosage (1.5 mg/kg/day). All patients started the therapy the day after thyroidectomy, and the drugs ...

Objectives: Anaplastic thyroid cancer (ATC) is one of the deadliest cancers, with a median overall survival (OS) of 4 months and a disease-specific mortality of ˜100%. Although to date no effective treatment can cure the disease, some anecdotal cases achieved longer survival and very rarely the cure of the disease. Multimodal treatment with surgery, radiotherapy, multikinase inhibitors (MKI) could improve survival in ATC, particularly when surgery is not feasible.<p c...

Anaplastic thyroid cancer (ATC) is usually treated with surgery, external hyperfractionated radiation therapy, and chemotherapy. However, because of the aggressiveness of this type of cancer, these treatments allow about 6-10 months of median survival. Therefore, it is challenging to predict the ATC patient clinical therapy responsiveness. Pazopanib is a multitarget tyrosine kinase inhibitor of VEGF receptors, PDGF, and c-Kit, and its effect in primary human ATC cells (pATC) h...

Background: The evaluation of postoperative adrenal insufficiency (PAI) and hypothalamus–pituitary–adrenal (HPA) axis recovery in patients with adrenal incidentaloma (AI) undergoing unilateral adrenalectomy remains limited.Objectives: We aimed to identify predictive factors for PAI development and evaluate HPA axis recovery in AI patients undergoing unilateral adrenalectomy.Methods: We retrospectively analysed adrenal fun...

A middle aged woman was admitted to Salisbury District Hospital after she was found to be severely hyponatraemic by her GP. She had been suffering from lightheadedness, headaches and tiredness for a few weeks before her admission but there was no obvious aetiology. Her past medical history included hypertension but she was not on diuretics or any other medication that could affect her sodium levels. Her serum sodium at the GP surgery was 123 and when she was admitted in the Ac...

Craniopharyngiomas are rare lesions derived from cell remnants of Rathke’s pouch, usually localized in the sellar and suprasellar areas.Objectives: To analyze clinical, endocrine and histological features in a group of patients from Buenos Aires city. To assess efficacy, number of surgeries and complications after surgery or other treatments.Material and methods: Multicentric, retrospective, transversal study. Adult patients w...

A 52-year-old male patient with no past medical history of interest was admitted to our Endocrinology Unit with a clinical course developed in the last month of sudden polyuria, nocturia and polydipsia (8 liters/day) associated with bilateral low back and leg pain, a right-side nasal congestion with eye swelling and paresthesia. Physical examination revealed a doubtful thickening of the nasal mucosa and several two-cm- scattered erythematous disseminated skin lesions. Blood sa...

Background: Long-term studies evaluating mortality in patients with non-functioning (NF) pituitary tumors (PitNets) are limited, although standardized mortality ratios (SMR) in these patients are reported to be higher than that of general population. There is also no agreement on predictive factors associated to the increased mortality apart from age at diagnosis and glucocorticoid substitution therapy dose.Objective: To assess long-term mortality and as...

Introduction: The spectrum of corticotroph cell pituitary adenomas is very wide, silent corticotroph adenomas (SCAs) being a rare subtype with positive immunohistochemistry for adrenocorticotropic hormone (ACTH), without causing Cushing’s disease. SCAs may exhibit a more aggressive behavior, and the changing of the clinical phenotype towards Cushing’s disease is described. Case report: We present the case of a 74 years old, ex-smoker, hypertens...
