Introduction: Chromogranin A continues to be one of the most valuable markers for neuroendocrine tumors (NETs) however, it has several limitations, including its reduced specificity.Methods: The authors present the case of a patient diagnosed with a midgut NET, during follow-up.Results: Male patient, 61 years old, with chronic renal disease (CRD), underwent right hemicolectomy owing to ileo-cecal valve lesion; hist...

Cyclic Cushing’s disease is a rare situation due to episodic hypersecretion of ACTH. Suspicion is raised when strong clinical stigmata occur, with normal basal values of cortisol and normal responses to dynamic tests. After performing several tests, particularly during phases without symptoms (well-being), the probability of successful diagnosis increases.We describe the case of a 33 years old female patient with full-blown clinical picture (weight ...

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: 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...

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: Continuous subcutaneous insulin infusion (CSII) and multiple daily injections (MDI) are forms of intensified insulin therapy and the most used regimens for type 1 diabetes (T1D). Owing to its continuous basal output, hypoglycaemic events tend to be rarer with CSII. Our goal was to evaluate the differences in nocturnal hypoglycemia between these two treatment strategies.Methods: Retrospective analysis of 61 patients who had performed continu...

Introduction: Many patients with diabetes experience high variability in glucose concentrations which is associated with a risk of hypoglycemia. The aim of this was to compare the predictive value of HbA1C, mean interstitial glucose (MIG), and glucose variability (GV) in the risk of hypoglycemia in patients with type 1 diabetes (T1D).Methods: Continuous glucose monitoring, using CGMS system, was performed in 130 T1D patients with diabetes duration of 17....

Introduction: Adrenal hematomas are very rare entities. They occur often associated with: trauma, anticoagulation, coagulopathy, septicemia, pregnancy complications or tumors. When none of these predisposing factors is present, diagnosis and treatment can become a real challenge.Case report: A 19-years-old woman presented with complaints of asteny, loss of appetite, loss of 10 kg in a month, and pain in right lumbar and abdominal regions. No other compla...

Resistance to thyroid hormones (RHT) is a rare syndrome, with autosomic dominant transmission, due to mutations in thyroid hormones beta-receptor gene. Clinical presentation is variable for the same mutation. This hypothesis must be considered in presence of high levels of thyroid hormones and TSH not suppressed.The evaluation of a 15-year-old female patient, in 1990, harbouring a thyroid nodule, secondary amenorrhea and visual and auditory impairment sh...
