Adrenal “incidentalomas” refer to a group of adrenal masses initially discovered during cross-sectional imaging obtained for other clinical reasons. The majority of incidentalomas are benign nonfunctional adrenal adenomas and can be safely managed expectantly. A subset of adrenal incidentalomas, however, are functional and/or malignant, and these lesions most often require adrenalectomy. The fo...

Disseminated histoplasmosis affecting the adrenal gland(s) of immunocompetent adults is a very rare infection. Here, we present a case of bilateral adrenal histoplasmosis in an immunocompetent, 62-year-old gentleman from Texas along with a brief review of the published literature. Given the risk of patient decompensation secondary to adrenal insufficiency and the wide availability of effective ...

Adrenal incidentalomas are unexpectedly identified adrenal masses without prior suspicion of the existence disease. The majority benign adenomas (80-90%), and they non-functioning adrenocortical in more than 70% cases. Mild hypercortisolemia is most common finding hormonally active incidentalomas. It defined as autonomous cortisol secretion up to 15% patients. Despite a lot research that antici...

Adrenal length and width were determined from two-dimensional ultrasound longitudinal images. In study 1, 540 measurements of adrenal glands were attempted from five healthy beagle dogs by three different observers with different levels of expertise in ultrasonography, to determine the variability of adrenal gland measurements. Of these, 484 measurements were included in the statistical analysi...

The fetal pituitary-adrenal axis plays a key role in the fetal response to intrauterine stress and in the timing of parturition. The fetal sheep adrenal gland is relatively refractory to stimulation in midgestation (90-120 days) before the prepartum activation, which occurs around 135 days gestation (term=147+/-3 days). The mechanisms underlying the switch from adrenal quiescence to activation ...

In order to elucidate the role of substance P in adrenal nerve activity, the effects of substance P antagonists on tonic activity of the adrenal sympathetic nerve, the response to exogenous substance P and cutaneo-adrenal nerve reflex were investigated in anesthetized rats. Substance P or its antagonist [(Arg1, D-Trp7,9, Leu11)-substance P: spantide] was injected into the subarachnoid space via...

BACKGROUND Poly(ADP-ribose) polymerase (PARP) participates in multi-organ failure in various inflammatory diseases including acute necrotizing pancreatitis (ANP). Since pancreatitis-associated adrenal insufficiency is partly caused by inflammatory damage to the adrenal cortex, we examined whether PARP antagonism could alleviate adrenal insufficiency in a rat model of ANP. METHODS ANP was indu...

Adrenal hypoplasia is an invariable finding in infants with anencephaly. Hypoplastic adrenal glands have been described in infancy associated with congenital hypoplasia of the pituitary gland (Mosier, 1956). S;kl (1948) was probably the first author to describe congenital adrenal hypoplasia unassociated with other congenital abnormalities, though he mentions some similar cases described by earl...
