Preterm delivery (PTD) and preeclampsia (PE) are ‘obstetric syndromes’, characterized by complex pathogenesis and representing major causes of perinatal mortality and morbidity. Although therapeutical treatment have been developed, their incidence is not reducing. Prevention aims to preclude development of disease by eliminating/reducing risk in women with known risk factors.The feto-placental unit produces hormonal/neuronal/immune factors, cru...

Adrenocortical carcinoma (ACC) is a rare and highly aggressive endocrine neoplasm, with limited therapeutic option. Activating β-catenin somatic mutations are observed in ACC and associated with a poor outcome. Activation of the Wnt/β-catenin signaling pathway seems to play a major role in ACC aggressiveness, and might be a promising therapeutic target. The H295 cell line derived from an ACC harbors an activating β-catenin mutation. We herein assess the in vi...

Introduction: It has been reported that vitamin D deficiency is common in patients with primary hyperparathyroidism (pHPT), and this could affect the clinical expression of the disease. However only few studies addressed this issue and refer to American or North European patients. In these studies, only about one third of the patients showed a vitamin D replete state.Subjects and methods: In 207 consecutive pHPT patients (M/F=45/162, age (mean ±<sma...

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/...

Recent years have been marked by numerous advances in the quality of type 1 diabetes care. However, glycemic control remains suboptimal for many patients even in developed countries.The aim of this study was to assess glycemic control in a cohort of Tunisian type 1 diabetic patients and to identify factors associated with poor glycemic control.Methods: One hundred and eighty-eight type 1 diabetic patients admitted to the Endocrinol...

Introduction and objective: The pregnancies in women with pregestational diabetes are associated with increased risk of abortion, birth defects, complications of pregnancy and perinatal morbidity and mortality. Pregnancy planning would be associated with better metabolic control, and therefore better obstetric and perinatal outcomes. The objetive of this study has been to evaluate the obstetric results of women with pregestacional type 1 diabetes and compare planned with not p...

Context: The influence of beta cell replacement on daily glucose profile in Type 1 diabetes mellitus (T1DM) is not firmly established.Objective: To examine the influence of islet transplantation (IT) on the various component of dysglycemia in T1DM patients.Design, setting and patients: Single arm open labeled study. Twenty-three consecutive patients with T1DM, 11 males and 12 females, 14 non uremic and 9 uremic with a previous kidn...

Atypical parathyroid adenomas represent a subset of tumors with histological features worrisome for carcinoma (PC), such as trabecular growth, fibrous bands and increased mitotic activity without unequivocal criteria of malignancy (local recurrence and/or metastasis). The question of whether these lesions might represent an anticipation of an aggressive clinical behavior that overtime may acquire the full blown features of malignancy remains to be established.<p class="abs...

Recently, we investigated effects of the Tumor-VDA ASA404 in tumor models for neuroendocrine tumors of the gastroenteropancreatic system and adrenocortical carcinoma 24 hours after treatment of BON and NCIh295 tumor bearing mice with ASA404 (A), paclitaxel (P) or the combination (A+P). We detected for BON tumors extensive necrotic areas as well as a significant decrease in cell proliferation, increase of apoptotic cells and reduction of microvessels after A or A+P treatment wh...

Introduction: Survival rates in childhood cancer survivors (CCS) have enormously increased in the last 40 years. However, this improvement has been achieved at the expense of serious late effects, including the potential for severe gonadal damage. Here we report the effects of anticancer therapies on gonadal function in male long-term survivors of childhood cancer.Methods: We estimated, at the last follow up available, the prevalence of primary hypogonad...
