Trabecular bone score (TBS) evaluates bone microarchitecture by measuring the grey-level variations from lumbar spine dual-energy X-ray absorbtiometry (DXA) images. Bone mineral density (BMD) in various endocrinopathies might not be sufficient in assessing bone fragility, especially in patients with acromegaly (ACM) but also in thyrotoxicosis. The aim of our study was to evaluate bone quality and quantity by BMD and TBS in patients with acromegaly and thyrotoxicosis.<p cla...

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, ...

Background: Diabetes mellitus is a metabolic disease associated with an increased risk of fracture, despite normal or increased bone mineral density (BMD), especially type 2 diabetes mellitus (T2DM). Trabecular bone score (TBS) is an imaging investigation that measures the grayscale variations on the lumbar spine performed on the DXA machine. The aim of this study was to evaluate the determinants associated with low BMD and TBS in patients with type 1 and type 2 diabetes melli...

Background: Medullary thyroid carcinoma (MTC) is a rare thyroid neoplasm with a high degree of malignancy derived from the parafollicular calcitonin-secreting cells. This carcinoma may occur sporadically in about 80% of cases or it may be part of the autosomal dominant multiple endocrine neoplasia (MEN) type 2. While the 10-year survival rate is around 40–75%, for metastatic disease, it’s just below 20%.Case presentation: We report the case of ...

Background: Osteoporosis is a chronic metabolic bone disease, highly prevalent in the elderly population, especially in postmenopausal women. Denosumab is a potent anti-resorptive drug, which can be used as an initial therapy or as an alternative therapy in the treatment of osteoporosis.Objective: We aimed to analyze the characteristics of patients, the evolution of bone mass density (BMD) and trabecular bone score (TBS) and the factors associated with f...

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 ...

A rare and aggressive form of thyroid malignancy, medullary thyroid carcinoma (MTC) is virtually incurable except by complete surgical resection. Due to its insidious onset and extensive spread at diagnosis, its prognosis is often poor.Aim: To evaluate treatment outcome and prognosis in patients diagnosed with MTC admitted to our department between 2004 and 2013.Patients and methods: We identified 21 patients (eight men and 13 wome...

Aim: Most research teams analyze the evolution of patients with Hashimoto thyroiditis (HT) on syndromic basis (e.g., the thyroid function), not on pathogenic basis (the autoantibodies). Thus, most researchers refer to thyroid hormone evolution. In this study we re-analyzed (first in 2018) how evolve the antithyroid autoantibodies. Therefore, we analyzed the antithyroperoxydase antibodies (ATPO) evolutive patterns in patients with HT.Method: 1. ATPO level...

A 42-years woman presented with hypothyroidism, a large, firm, irregular goiter, severe cervical and preauricular pain, 2 weeks after an episode of respiratory infection. Laboratory findings certified subacute thyroiditis and autoimmune hypothyrodism: TSH>50 μUI/ml, FT4=6.5 pmol/l, ATPO>1000 U/ml, ATGL>1000 U/ml, ESR=115 mm/1 h. Thyroid ultrasound showed hypoechogenic pattern with a nodule on the right lobe and low Doppler signal. Fine needle aspira...

Background: Acromegaly is characterized by increased prevalence of fragility vertebral fractures. Nonetheless, there are no clear recommendations for prevention of acromegalic osteopathy. Both bone mineral density (BMD) and trabecular bone score (TBS) lack clear evidence as prognostic factors for vertebral fractures (VF).Material and Methods: We performed an observational study on 31 acromegalic patients recruited prospectively. They were tested for alka...
