Steroids are still widely prescribed in pituitary trans-sphenoidal surgery (TSA). Pituitary-adrenal/thyroid/gonadal functions were prospectively evaluated in 72 consecutive NFPA pts (20–87 years, 37 M) before and after endoscopic-TSA (E-TSA) (63 at first operation, 9 at re-operation). All had macroadenoma with suprasellar extension: impinging optic chiasma in 28, extending into cavernous sinus (CS) in 23, giant in 12. Hydrocortisone was infused peri-operatively only in pt...

Silibinin, a milk thistle extract with known hepatoprotective effects, has recently been shown to act upon tumoral corticotropes and revert the Cushingoid phenotype in an allograft mouse model (Riebold et al. 2015). Silbinin is known to inhibit HSP90 -a chaperone to the glucocorticoid receptor-thereby restoring sensitivity to glucocorticoid negative feedback in tumoral corticotropes. Aim of the present study was to assess the effect of silibinin on ACTH synthesis and ...

The rate of diagnosis of pituitary adenomas in the elderly is increasing, as a consequence of the improved life expectancy. The management of elderly patients affected by pituitary adenomas are still a subject of debate in literature. In particular, data on the safety of endoscopic transnasal transsphenoidal surgery (TNS) are still controversial. The primary endpoint of the present study is to assess the surgical outcome of a cohort of patients who underwent TNS for non-functi...

In this observational, retrospective, multicenter study, we analyzed data from 300 patients with pituitary incidentaloma followed in two Italian Hospital Center. We observed a predominance of female patients (65%), with an a mean age at diagnosis of 49 years (higher in men than women, 57 vs 45 years old). The main reason to perform imaging were neurological symptoms not related to the presence of adenomas (56%). Most cases were microadenomas (56%), and macroadenomas were more ...
