Introduction: Acromegalic bone disease is characterized by an increased prevalence of fragility vertebral fractures (VFs). However, an effective, non-invasive and cost-efficient imaging technique that can diagnose early bone alterations in this category of patients is yet to found. The use of bone mineral density (BMD) is not as useful as in other causes of osteoporosis as excess GH leads to specific microarchitectural alteration of trabecular bone, which don’t translate ...

Background: Dopamine agonists (DA) are the first-line treatment for macroprolactinomas. However, up to 10% of patients fail to respond to medical therapy.Aim: To assess biochemical resistance rate to DA treatment in a large series of patients with macroprolactinoma and to analyze possibilities to overcome this resistance.Patients and methods: 195 patients with macroprolactinomas, treated with DA for at least 2 years, were retrospec...

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...

Neuroendocrine tumors (NETs) represent the second most common malignancy of the small bowel (SB) and despite their indolent nature, NET liver metastasis (NETLMs) will develop in 50 to 60% of patients. Although there have been recent advances in the therapeutic armamentarium in patients with advanced NETs, surgical resection remains the only potentially curative intervention for patients with NETLMs. However, patients whose liver has been significantly invaded by the tumour (mo...

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, ...
