Introduction: Cushing’s Syndrome (CS) has been associated with bone mass abnormalities and with an increased risk of osteoporotic fractures.Objective: Evaluate the effect of treatment on the 10-year probability of fracture predicted by FRAX® and on the overall bone profile, in patients with CS.Patients and Methods: We evaluated 36 patients (6 M, 30 F, 12 post-menopausal, mean-age 43.6±13.5), 22 with Cushin...

Introduction: Primary hyperparathyroidism (pHPT) is characterized by an increased frequency of glucose tolerance abnormalities associated with insulin-resistance. Few studies evaluated the relationship between insulin resistance and others cardiovascular risk factors in pHPT.Subjects and methods: In 255 consecutive pHPT patients (M/F=66/189, age (mean±S.D.): 59.9±13.7 years, PTH: 215.6±219.4 pg/ml, calcium: 11.2±1.2 mg/...

Introduction: Calcium plays a key role in myocardial contractions and relaxation. Heart failure induced by hypocalcemia is rare but potentially reversible case.Case report: We present the case of 50 years old woman with muscle cramps, cataract, chest pain and dyspnea that lasts 2 years. In regional health center she was treated as psychiatric patient and COPD. Last few months she became extremely malaise with crural edemas and walking distance of 100 m. ...

Introduction: The current epidemic of Type 2 Diabetes Mellitus (T2DM) and obesity is positively correlated with a rise in consumption of high-fructose syrups and refined carbohydrates. Recent reports have showed that feeding rodent a high-fructose diet leads to insulin resistance, glucose intolerance and dyslipidaemia. Nevertheless, its mitochondrial effects has not been fully studied yet.Aim: We decided to explore the alterations in mitochondrial bioene...

Background and Aim: Klinefelter syndrome (47,XXY; KS) is a very common chromosomal disorder, affecting 1:600 men. Klinefelter men have been described to exhibit clinically relevant metabolic patterns related to a pro-inflammatory status, resulting in a high prevalence of insulin resistance and cardiovascular impairment. Testosterone deficiency in form of primary hypogonadism is a common feature in these men.EXAKT (epigenetics, X-chromosomal features and ...

Objective: Melatonin is a hormone secreted by the pineal gland which modulates sleep and wakefulness rhythms. Decreased melatonin secretion has been shown to be associated with increased daytime sleepiness and disturbed circadian rhythm in (irradiated) survivors of childhood craniopharyngeoma. The present study was performed to explore possible relationships between disturbed sleep, psychosocial impairment and melatonin secretion in patients treated with cranial radiotherapy a...

Thyroid cancer is the most common endocrine malignancy characterized by a good prognosis. However, the subgroup of poorly differentiated thyroid carcinomas (PDTCs) includes neoplasia highly aggressive and scarcely responsive to currently available therapies.Site-selective cAMP analogs are able to inhibit the growth of poorly differentiated solid tumors and may represent valuable candidates for the therapy of PDTCs.We evaluated the ...

Fetal exposure to environmental estrogens may contribute to hypofertility and/or to testicular germ cell cancer. However, many of these endocrine disruptors have only a weak affinity for the classical ERs and other mechanisms have been suggested. Bisphenol A, a chemical poluttant, used as monomer to manufacture polycarbonate plastic, released from lining canned food or beverages or from dental sealants, was able to promote human testicular seminoma cell (JKT-1) proliferation <...

The global warming and its impact on the summer average temperature elevation, in the south-eastern parts of Europe, represent an inevitable stress for living organisms in this region. Heat stress was shown to be the strongest one, when compared to immobilization or cold stress. Activation of the hypothalamo-pituitary–adrenal (HPA) axis during exposure to various types of stressors is well-known physiological concept. The effect of 24 h exposure to heat stress on the morp...

Objective: To evaluate Vitamin D levels and bone metabolism in adult patients with cystic fibrosis (CF).Patients and methods: One hundred patients with CF (53 F, 47 M; age 29±8 years). and 100 healthy controls were enrolled. Patients were assessed through clinical, and laboratory investigations. Evaluation of serum 25 hydroxy vitamin D (25OHD), vertebral fractures (quantitative morphometric analysis) and bone mineral density (BMD) at lumbar spine an...
