Introduction: Alemtuzumab is a humanized anti-CD52 monoclonal antibody approved for the treatment of relapsing−remitting multiple sclerosis (RRMS). Through an immune reconstitution mechanism, it leads to thyroid autoimmunity in 35% of cases, with Graves’ disease (GD) being the most common presentation. Alemtuzumab-induced GD exhibits distinctive clinical and immunological features, with rarely reported cases of fluctuating thyroid status with documented both blockin...

We describe the case of a 69-year-old woman with bilateral adrenal incidentalomas identified in CT-scan: on the right, a 57 mm heterogeneous mass with <10 Hounsfield units(HU) with absolute washout of 16%; on the left a 13 mm mass with 35UH, intense contrast enhancement but washout of 66%. She had a recent onset of diabetes, hypertension, androgenic alopecia and facial hair. The systolic blood pressure remained persistently >160 mmHg despite receiving four antihyperten...

Introduction: Pheochromocytomas are rare neuroendocrine tumors whose malignancy is defined by the presence of metastases that may appear several years later. The appropriate follow-up time remains uncertain.Clinical Case: We present the case of a woman with a history of pheochromocytoma who underwent complete resection at 48 years old. The genetic evaluation was negative for mutations on RET, VHL, SDHB or SDHD genes. At 66 years old, a thoracic vertebral...

Introduction: The effects of long-term replacement therapy of primary adrenal insufficiency (PAI) are still a matter of debate. Glucocorticoid (GC) replacement regimens do not completely mimic the endogenous hormonal production and their monitoring is sometimes difficult. Therefore, some patients are exposed to mild GC excess with potential complications, such as hypertension, diabetes, and skeletal fragility. Data on bone mineral density (BMD) in PAI is still scarce and contr...

Introduction: Pseudohypoparathyroidism is a heterogeneous disease characterized by hypocalcemia, hyperphosphatemia and parathyroid hormone resistance. The distinct pseudohypoparathyroidism types are distinguished by physical features, the coexistence of other hormone resistances and genetic defects. Pseudohypoparathyroidism type Ib is more often associated with sporadic cases, unlike others types.Clinical Case: Male, born in France, diagnosed with pseudo...

Thyroid hormone resistance syndrome(THRS) occurs in 1:40000 live births and can be diagnosed after a period of enigmatic changes in thyroid hormones(TH). Patients may be clinically euthyroid, have clinical hypo or hyperthyroidism. Mostly, it is an autosomal dominant disease due to germline mutations in THRβ-gene(exons 7-10). Resistance to peripheral action of TH leads to absence of TSH suppression (which can be normal/elevated) despite elevated fT4 and fT3.<p class="a...

Introduction: Type 1 diabetes (T1D) is the most frequent children’s endocrinopathy in Portugal. The duration of the disease and metabolic control may affect the final height of pediatric patients. Despite the metabolic advantages of technological advances, such as continuous subcutaneous insulin perfusion (CSII), the effect on growth is unclear.Aim: To assess the impact of T1D treatment, with multiple daily injections (MDI) or CSII, on growth.<p...

Introduction: Evidence has suggested a relationship between female obesity and the outcomes of medically assisted reproduction techniques (MRT); however, the evidence regarding male obesity is still scarce and discordant. Aim: Evaluate the influence of female and male obesity on the results of MRT.Materials and methods: Retrospective analysis of 2159 couples, with and without obesity, submitted to the first treatment of medically a...

Introduction: Inferior petrosal sinus sampling (IPSS) has been considered to be the gold standard for differential diagnosis of Cushing’s Disease (CD) and ectopic ACTH secretion (EAS).Aim: To describe the experience of our centre in performing IPSS, its safety and efficacy; assess remission rates from transphenoidal surgery and clinical course; approach to the difficulty in the etiological diagnosis of ACTH-dependent Cushing’s Syndrome.<p c...

Introduction: Thyrotoxic crisis is a rare endocrinological emergency with high mortality and it is more frequent in Graves’ disease.Clinical case: A 66-year-old women with schizophrenia was admitted to the Emergency Department due to altered state of consciousness, fatigue, constant moaning interspersed with unusual psychomotor agitation, heteroaggressiveness, diarrhea and anorexia. Lack of compliance with her psychiatric medication, new delusional ...
