Introduction: Multiple endocrine neoplasia type 1 (MEN1) is a rare, autosomal dominant inherited syndrome caused by mutations in the MEN1 tumor suppressor gene and is characterized by the occurrence of parathyroid, pancreatic islet and anterior pituitary tumors. We present the case of a female patient known to have pituitary and parathyroid tumors in a MEN1 syndrome evolving for more than 20 years before associating pancreatic neuroendocrine tumor.Case r...

Introduction: Radioactive iodine-refractory differentiated thyroid cancer is a rare form of advanced thyroid cancer (approximately 4 cases per million population per year) defined by persistent disease after administration of a cumulative radioiodine dose of 600 mCi or at least one tumor without radioactive iodine uptake or by progression of the disease within one year after RAI treatment. Therapeutic options in this case include molecular-targeted therapies, like tyrosine kin...

Introduction: Acromegaly has various complications that significantly alter patients’ lives, one of which is developing neoplasia, a subject of high interest in the scientific community during the last years but without any firm conclusions.Aim: The main objective of this paper was to verify if Romanian acromegalic patients are susceptible to developing neoplasia and what types of tumors are associated with acromegaly. Another purpose of the paper w...

Objective: Patients with pituitary macroadenomas and concomitant hypopituitarism have a reduced life expectancy due to various comorbidities.Aim: To investigate mortality in patients with non-functioning pituitary adenomas (NFAs) and independent prognostic factors influencing survival.Design: Retrospective cohort study in a tertiary neuroendocrine university department.Methods: A total of 364 patients (177F/1...

Background: Thyroid nodules were reported with high prevalence in acromegalic patients.Patients and methods: 63 acromegalic patients (16 males and 47 females), aged at diagnosis 43.6±12.7 years were retrospectively reviewed. Median duration of acromegaly was 8 years. 25 patients were residents in iodine deficient areas. GH, IGF1, TSH, FT4 were measured by chemiluminescence (Liaison). Thyroid ultrasound was performed. In suspected nodules,...

Introduction: The new tool FRAX indicated risk of fracture, using or not DXA which is the golden standard for osteoporosis diagnosis.Aim: We analyzed the lumbar DXA correlations with 10-year fragility fracture risk probability.Material and method: A cross sectional study in postmenopausal women was designed. They were osteoporosis free at baseline; none of them has previously been treated for osteoporosis. The anamnesis, the anthro...

Background: Hyperthyroidism is widely known to be an important cause of secondary osteoporosis through the accelerated rate of bone turnover, while primary hyperparathyroidism is typically associated with loss of cortical bone and less so of trabecular bone, as seen on dual-energy x-ray absorptiometry (DXA). The evaluation of bone quality in these categories is not fully understood and needs further research. The aim of this study was to compare the bone quantity and quality, ...

Introduction: Gastrinoma is rare gastrin-secreting neuroendocrine tumor (NET), usually located in the pancreas or duodenum. The most common presentations of gastrin secreting tumor is Zollinger-Ellison Syndrome (ZES). Only about 10% of patients have non demonstrable ulcer.Case presentation: A 67 years old female, with premature menopause, mild hypothyroidism with optimal replacement treatment, osteopenia and history of chronic gastritis, is admitted to o...

Introduction: Pituitary tumours may interfere with fertility and pregnancy may be uncommon in these cases, but some patients can conceive spontaneous. Also in pregnancy, due to the physiologic changes of the pituitary gland, gradual volume increase and cellular hyperplasia that target hormonal secretion, the evaluation of the pituitary function is very complex.Clinical cases: We present 5 cases of female patients (24 – 35 years old) that were diagn...

Background: Primary hyperaldosteronism or Conn’s syndrome is one of the adrenocortical causes of hypertension, alongside hyperdeoxycorticosteronism, apparent mineralocorticoid excess and Cushing syndrome. The two types of hypertension-inducing adrenocortical syndromes (Conn’s and Cushing) are extremely rare to be decribed in the same patient. We describe a case of a patient with clinical and biochemical evidence of Conn’s syndrome due to a left adrenal adenom...
