Low Protein Expression of both and as Novel Negative Prognostic Markers of Adult Adrenocortical Carcinoma.

Adrenocortical carcinoma (ACC) is a rare malignancy that is associated with a dismal prognosis. Pan-genomic studies have demonstrated the involvement of and genes in adrenocortical tumorigenesis. Our aims were to evaluate the protein expression of and in a cohort of 82 adults with ACC and to establish their prognostic value.

A New Insight into the Surgical Treatment of Primary Macronodular Adrenal Hyperplasia.

Purpose: This prospective study presents the results of a new approach in the treatment of primary macronodular adrenal hyperplasia (PMAH), with simultaneous total adrenalectomy of the larger adrenal gland and partial adrenalectomy of the contralateral adrenal gland (adrenal-sparing surgery).

Materials And Methods: We performed a prospective study including 17 patients with PMAH treated surgically with adrenal-sparing surgery in a tertiary referral hospital, with a median follow-up of 41 months. Clinical, hormonal, and genetic parameters were evaluated before surgery and during follow-up.

Allelic Variants of in Patients With Adrenal Incidentalomas and in Patients With Cushing's Syndrome Associated With Bilateral Adrenal Nodules.

Germline mutations are considered to be the main genetic cause of primary macronodular adrenal hyperplasia (PMAH). PMAH is associated with high variability of cortisol secretion caused from subclinical hypercortisolism to overt Cushing's syndrome (CS), in general due to bilateral adrenal nodules and rarely could also be due to non-synchronic unilateral adrenal nodules. The frequency of adrenal incidentalomas (AI) associated with PMAH is unknown.

Percutaneous puncture of renal calyxes guided by a novel device coupled with ultrasound.

Purpose: To evaluate the efficiency of a novel device coupled with ultrassound for renal percutaneous puncture.

Materials And Methods: After establishing hydronephrosis, ten pigs had three calyxes of each kidney punctured by the same urology resident, with and without the new device ("Punctiometer"). Time for procedure completion, number of attempts to reach the calyx, puncture precision and puncture complications were recorded in both groups and compared.
