Here we report the case of a woman with first presentation of Addison disease in pregnancy that went undiagnosed until postpartum period. She gave birth to a healthy child by vaginal delivery at 40 weeks of pregnancy. Our patient is a 31 years pregnant woman with unremarkable medical or familial history. At 8 weeks of pregnancy she was complaining of nausea, vomiting, loss of appetite and fatigue, leading to hospitalization. The physical examination revealed a blood pressure o...

Background: Patients with CHH and KS have eunuchoid body proportions of the skeleton compared to normal male subjects, characterized by tall stature, and reduced upper-to-lower segment ratio (U/l). Vice versa, steroids exposure deeply differs between CHH and KS at puberty, with both testosterone and estradiol being very low only in CHH. At present, body skeletal proportions comparison between CHH and KS is not available.Aim: To compare anthropom...

Introduction: Polycystic ovary syndrome (PCOS) is the leading cause of female infertility and is associated with high degree of comorbidities including type 2 diabetes and endometrial cancer. Hyperandrogenemia is a hallmark of PCOS and contributes to endometrial-related dysfunctions, including implantation failure and miscarriage. Whether cellular heterogeneity contributes to the functioning of the endometrium is not previously studied. Therefore, the aim is to reveal cell-typ...

Background: Erectile dysfunction (ED) represents the most frequent sexual dysfunction. Among several possible ED aetiologies, vascular ED (vED) presents the greatest implications for global individual health, resulting an early hallmark of cardiovascular diseases. Indeed, vED was demonstrated associated with a 1.25 times greater risk of developing major cardiovascular diseases. Alongside cardiovascular aspect, the evaluation of patients health, measured by the comorbidities nu...

Thyroid hormones (TH), among their pleiotropic actions, play a central role in the regulation of metabolism and in cognitive functions. Indeed, hypothyroidism is associated with a decrease in energy expenditure and lipid metabolism, and an impairment of memory. Metabolic deregulations induced by a high fat diet (HFD) generate peripheral inflammation, which promotes the development of neuroinflammation in various brain regions. This inflammatory state can disrupt neuronal homeo...

Background: The 5-year survival rate for patients with unresectable, metastatic pancreatic neuroendocrine tumors (pNETs) remains less than 30%, emphasizing the need for new and effective treatment options for patients with advanced pNETs. Notch1 signaling is a critical cell-cell communication pathway responsible for regulating differentiation, cell fate determination, and epithelial-mesenchymal transition (EMT). Notch1 plays a critical role in the differentiation state of NE c...

Recently, a position statement of a working group for renaming diabetes insipidus (DI) appeared in several renowned endocrine journals aiming to promote a change in the established name of DI. According to this position statement, the major arguments for renaming DI are: (a) it does not optimally reflect the underlying pathophysiology (b) it is often confused with diabetes mellitus (DM) leading to treatment errors and consequent adverse outcomes for patients. Although the abov...

Neuroendocrine neoplasms (NENs) are a highly heterogeneous group of tumors that arise from the diffuse neuroendocrine system and whose incidence has increased over the last years. Among them, pancreatic NENs (PanNENs) are relatively common and one of the most studied NENs. PanNENs are characterized by a low number of mutations, with some genes frequently mutated, such as MEN1, ATRX/DAXX, and mTOR signaling pathway genes. Despite genomics, transcripto...

Background: Molecular mechanisms of malignant adrenocortical tumorigenesis remain elusive despite previous comprehensive genomic studies. Nonetheless, cellular heterogeneity of primary, recurrent and metastatic adrenocortical carcinoma (ACC) haven’t been fully investigated.Aim: To characterize the molecular profile of different cell subtypes in primary, recurrent and metastatic ACC by single-nuclei RNA sequencing (snRNA-Seq), using adult human norma...

Metabolic disorders, such as overweight and obesity, are serious health societal challenges due to their high incidence rates. Obesity leads to metabolic dysregulation, promoting hormonal imbalance, oxidative stress, and a chronic inflammation state. Eating habits towards the intake of highly caloric fat-rich regimes induce epigenetic changes in the information transgenerationally transmitted. Furthermore, obesity promotes carcinogenesis. It is known that the prostate is sensi...
