An adrenal incidentaloma that had appeared to produce dehydroepiandrosterone-sulfate in excess before immunohistochemical study of the tumor.

Adrenal incidentaloma is a clinically unapparent adrenal mass more than one cm in diameter detected during imaging performed not for adrenal disease. A 34-year-old man was evaluated for AI with a diameter of 3.5 cm in the left adrenal.

Latent Adrenal Insufficiency: Concept, Clues to Detection, and Diagnosis.

Unlabelled: In 1855, Thomas Addison described an illness now known as Addison disease (AD) caused by damage to the adrenal cortex and manifesting in weakness, weight loss, hypotension, gastrointestinal disturbances, and brownish pigmentation of the skin and mucous membranes. Corticosteroid supplementation, corticotropin (adrenocorticotropic hormone [ACTH] of medicinal use) test, and anti-adrenal auto-antibodies (AA) have come into use in the 100 years since Addison's death. Following the methodological innovations, 4 disorders which share impaired response to corticotropin in common have been discovered (i.

Comorbid Latent Adrenal Insufficiency with Autoimmune Thyroid Disease.

Background: Autoimmune thyroid disease (ATD) has been occasionally observed in patients with primary adrenal insufficiency (PAI). In contrast, less than 20 cases of comorbid PAI with ATD have been found in the English literature. One conceivable reason is difficulty in detecting latent PAI.

History of stress-related health changes: a cue to pursue a diagnosis of latent primary adrenal insufficiency.

Objective: Routine delays in the diagnosis of primary adrenal insufficiency (PAI) are well known and conceivably attributable to the absence of cues, other than anti-adrenal autoantibodies, to pursue subclinical PAI. Subclinical PAI is latent unless the afflicted patient encounters stress such as an acute illness, surgery, psychosocial burden, etc. It remains to be demonstrated whether a history of stress-related health changes is a useful cue to pursue a diagnosis of latent PAI.

Synthesis, characterization, and catalytic reactivity of a highly basic macrotricyclic aminopyridine.

The synthesis methods, physicochemical and structural characteristics, and catalytic reactivity of new macrocyclic proton chelators, N,N',N''-tris(p-tolyl)azacalix[3](2,6)(4-pyrrolidinopyridine) and N,N',N''-tris(p-tolyl)azacalix[3](2,6)(4-piperidinopyridine), are studied. The introduction of pyrrolidino and piperidino groups into the pyridine unit enables the enhancement of the synergistic proton affinity of the cavity of the macrotricycle giving a high basicity (pK(BH+) = 28.1 and 27.

Prevalence of maturity-onset isolated ACTH deficiency (IAD) in 2005: Japanese cohort studies.

The prevalence of isolated ACTH deficiency (IAD) in Japan remains to be determined. Both authors (T.Y.

Tablet formulation of levothyroxine is absorbed less well than powdered levothyroxine.

The comparative bioavailability of oral doses of levothyroxine (LT(4)) formulation taken as tablets, after being crushed, or chewed before swallowing has not been well studied. Three patients with hypothyroidism who showed persistent elevation of serum thyrotropin (TSH) despite taking 200, 150, and 125 microg of LT(4) tablets per day are presented. They did not show signs and symptoms of gastrointestinal illness that could interfere with the absorption of LT(4) nor history of such a condition.
