OBJECTIVE Adrenocortical scintigraphy has demonstrated clinical utility in the morpho-functional characterization of adrenal tumors. The aim of this study was to identify possible relationships between the scintigraphic pattern and endocrine and/or morphological data in a series of adrenocortical carcinomas. DESIGN AND METHODS Twenty-one patients with adrenocortical carcinoma (11 nonfunctioni...

OBJECTIVES Presentation of the risk of psychosis induced by the treatment of adrenal crisis with high doses of hydrocortisone. METHODS A case analysis in the context of the literature. RESULTS There are reported psychoses in the patients with adrenal hypofunction and hyperfunction. Psychoses following implementation of substitution with small doses of corticosteroids due to adrenal insuffic...

Amino acid induced acid and gastrin responses during intragastric titration at pH 2.5 and 5.5 were compared in normal subjects and duodenal ulcer patients with G-cell hyperfunction. The latter were identified on the basis of raised basal or maximal acid outputs and increased gastrin responses to feeding. In normal subjects the mixed amino acid meal stimulated only modest increases in serum gast...

PURPOSE: Adrenocortical adenomas are common, whereas adrenocortical carcinomas are rare. Discriminating between benign and malignant adrenocortical tumors using conventional histology can be difficult. In addition, adrenocortical carcinomas generally have poor prognosis and limited treatment options. MicroRNAs are short noncoding RNAs that are involved in regulation of gene transcription. EXPER...

Nonfunctional adrenocortical carcinoma is an extremely rare malignant tumor in children. Unlike the functional tumor which is detected early due to its hormonal presentation, nonfunctional tumor is detected at a later stage. Here we report a case of a 10 year old girl who presented with abdominal mass and symptoms of short duration. No hypertension and cushingoid features were seen. Serum alpha...

For years, otolaryngologists and voice therapists have warned voice patients that whispering causes more trauma to the larynx than normal speech. However, no large series of patients has ever been examined fiberoptically during whispering to test this hypothesis. As part of our routine examination, patients are asked to count from 1 to 10 in a normal voice and in a whispered voice. We reviewed ...

Adrenocortical cancer is a rare cancer with a very poor prognosis. The genetic alterations identified to date in adrenocortical tumors are limited. Activating mutations of the Wnt signaling pathway have been observed in more frequent cancers, particularly digestive tract tumors. We investigated whether Wnt pathway activation is involved in adrenocortical tumorigenesis. In a series of 39 adrenoc...

Background:Unilateral tumors or masses of the adrenal gland are common. They are categorized as either functional (hormone-secreting) or silent and as either benign or malignant. Adrenocortical tumors are rare in childhood, with an incidence of 0.3-0.5 cases per one million child-years. Almost half of childhood tumors are adrenocortical carcinomas (ACC). Most ACCs are sporadic, but specialy i...
