Vesuvius eruption that destroyed Pompeii in AD 79 represents one of the most important events in history. The cataclysm left behind an abundance of archeological evidence representing a fundamental source of the knowledge we have about ancient Roman material culture and technology. A great number of textiles have been preserved, rarely maintaining traces of their original color, since they are mainly in the mineralized and carbonized state.

No longitudinal studies investigated the incidence of VFx and SDI changes over time in SH. The aim of this study was to evaluate VFx risk and SDI changes in SH over time.

Context: It is unknown whether the metabolic effects of the removal of an adrenal incidentaloma (AI) can be predicted by the assessment of cortisol hypersecretion before surgery.
Objective: To evaluate the accuracy of several criteria of hypothalamic-pituitary-adrenal axis activity in predicting the metabolic outcome after adrenalectomy.
Design: Retrospective longitudinal study.
Objective: A common polymorphic variant of the growth hormone receptor (GHR) is because of genomic deletion of exon 3 and has been linked with increased responsiveness to exogenous GH. The impact of this polymorphism in acromegaly, a disease characterized by endogenous excess of GH and partial loss of IGF-I feedback on tumoural GH secretion, is not clear. The aim of this study was to investigate possible influences of d3GHR on the GH/IGF-I relationship and metabolic parameters in acromegaly.

Objective: The objective of the study was to determine the effect of the surgical and conservative approaches on the metabolic syndrome in patients with adrenal incidentalomas.
Objective: Few data are available regarding the need of steroid substitutive therapy after unilateral adrenalectomy for adrenal incidentaloma (AI). It is unknown whether, before surgery, the hypothalamic-pituitary-adrenal (HPA) axis secretion parameters can predict post-surgical hypocortisolism.
Aim: This study aimed to evaluate whether, in AI patients undergoing unilateral adrenalectomy, post-surgical hypocortisolism could be predicted by the parameters of HPA axis function.

Context: In patients with adrenal incidentalomas and subclinical hypercortisolism (SH), the factors influencing bone and the prevalence of vertebral fractures are debated. Spinal deformity index (SDI), which reflects bone quality, has never been evaluated.
Objective: The objective of the study was to investigate in these patients SDI and factors influencing the prevalence of fractures.
Objective: Subclinical hypercortisolism (SH) is suggested to exert a deleterious effect on bone. This effect and the role of gonadal status in male subjects are not fully elucidated. We evaluated bone mineral density (BMD) and prevalence of vertebral fractures in eugonadal male subjects with adrenal incidentalomas (AI) and without SH.

In type 2 diabetic subjects, cortisol secretion was found to be associated with the complications and metabolic control of diabetes. We evaluated cortisol secretion in 170 type 2 diabetic subjects and in 71 sex-, age-, and BMI-matched nondiabetic subjects.

To evaluate HPA axis activity in patients with type 2 diabetes mellitus (T2DM) in relation to the presence or the absence of subclinical parasympathetic or sympathetic neuronal dysfunction, we performed an observational study on 59 consecutive type 2 diabetic patients without chronic complications and/or symptoms of neuropathy or hypercortisolism. The following were measured: serum cortisol at 08:00 am and at midnight (F8 and F24, respectively), post-dexamethasone suppression cortisol, 24-hour urinary free cortisol (UFC), and morning corticotropin (ACTH).
