Abstract

Various antimicrobial solutions have been tested as additives for raw milk traditional cheeses, among which Nigella sativa cold pressed seed oil (NSSO) is recognized for its positive effect on the microbial quality of such products. The overall effect on the quality of enriched cheeses during ripening is still under extensive investigation. Three batches of traditional raw milk brined cheese were included in the current experiment: control cheese without Nigella sativa seed oil (NSSO) and cheese samples enriched with 0.2 and 1% w/w NSSO. Experimental cheese samples were analyzed in duplicates for total nitrogen content (TN), at 0, 14, 28 and 42 days of ripening, while single determinations of total nitrogen (WSN) and free amino acids (FAA) were performed at 14, 28 and 42 ripening days. The TN content revealed similar values for control cheeses and NSSO cheeses, and no significant differences were noticed within the three treatment groups (p >.05) throughout ripening. WSN values followed a significant rising shift in all cheeses during ripening, yet computing data obtained for the three considered treatments, despite an obvious higher WSN content of NSSO enriched cheeses, no statistical significance could be associated to this difference. The FAA composition of the experimental cheeses, varied quantitatively, by increasing with ripening time, but no qualitative variation was noticed during the follow-up period. The FAA composition of the did not vary significantly within treatments.

ABSTRACT

Introduction Cushing’s disease is a rare endocrine disorder characterized by persistent hypercortisolism due to excessive, autonomous ACTH secretion by a pituitary adenoma. Transsphenoidal adenomectomy is the main therapeutic option in Cushing’s disease. When imaging studies are unable to demonstrate an obvious pituitary mass complete tumor resection is difficult and often encumbered by risk of relapse. Medical therapy is a second-line option or the first-line treatment for patients with high surgical risk, incomplete surgical resection or relapse. Rarely classic clinical manifestations limit the selection of medical therapy for Cushing’s disease. Case presentation We present the case of a male patient with Cushing’s disease complicated with diabetes mellitus and severe hepatocytolisis syndrome with no visible pituitary adenoma on MRI studies. In the absence of technical equipment petrosal sinus sampling could not be performed in order to improve surgery outcome

Conclusion The presence of unbalanced diabetes and severe hepatocytolisis syndrome made it impossible to use steroidogenesis inhibitors (mitotane, ketoconazole, metyrapone, etomidate) or inhibitors of ACTH secretion as pasireotide that represent a new option in achieving control of hypercortisolism
