Objective: A prospective study to research the relationship between initial levels of prolactin in the development and outcome of patients with gestational trophoblastic disease.Material and method: A longitudinal study including 51 women attending the Reference Center of Gestational Trophoblastic Neoplasia of Rio de Janeiro- Brazil, with complete mole, and comproved histopatologic examination. All women were followed up until remission was achieved. The...

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...

Graves’ disease is characterized by the occurrence of antibodies against thyroid-stimulating hormone (TSH) receptor that stimulate the gland to produce T4 and T3. It can be accompanied by an infiltrative orbitopathy and oftalmopathy. Another seldom- regognized feature of this disease is thymic hyperplasia.The authors report the case of a 22-year-old woman with Graves’ disease (TSH receptor antibodies 178 U/l) with exuberant oftalmopathy and an ...

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 ...

High blood pressure is a common problem among patients in a Nephrology ward and outpatient clinic. However in those patients resistant to therapy, we must exclude a secondary cause. The authors present a case of a patient that was referred to our hospital due to complaints of headache, high blood pressure resistant to therapy (BP=240/130 mmHg), and images in renal ecography, which were compatible with enlarge left adrenal gland and left kidney atrophy. At admission the blood r...

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...

Neuromedin B (NB) is a peptide highly expressed in adipose tissue (AT) but its function remains unclear. We showed that NB receptor (NB) knockout mice (NBR-KO) are resistant to diet-induced obesity compared to wild type (WT) and now we aimed to analyze NBR influence in adipocytes. Mesenchimal cells from perigonadal AT of WT and NBR-KO mice were isolated and maintained in growth medium (GM) as control group or in differentiation medium (DM) as induced group. After 2 weeks cells...
