Cushing 's syndrome

We report a case of avascular necrosis (AVN), hypercalcemia, and iatrogenic Cushing's syndrome in an HIV-positive patient taking inhaled (ICS) and nasal corticosteroids fluticasone and ritonavir. A 45-year-old HIV-infected African-American woman was seen for initial evaluation for multinodular goiter in December 2015. Relevant medications were ritonavir, raltegravir, darunavir, fluticasone propionate HFA, and nasal fluticasone propionate. Physical examination revealed classical cushingoid appearance but laboratory testing showed abnormal adrenocorticotropic hormone (ACTH) stimulation test...

Since the initial discovery of mutations in the Armadillo -containing repeat protein 5 gene ( ARMC5 ) in primary bilateral macronodular adrenocortical hyperplasia (PBMAH), efforts have been made to better understand the molecular mechanisms involving ARMC5 in the development of this rare form of Cushing syndrome. It has now been established that germline ARMC5 -inactivating mutations, mostly frameshift and nonsense ones, are responsible for roughly 40% of PBMAH cases. ARMC5 is a tumor suppressor gene responsible for a familial form of PBMAH...

From the very beginning of his career, Harvey Williams Cushing (1869-1939) harbored a deep interest in a complex group of neoplasms that usually developed at the infundibulum. These were initially known as "interpeduncular" or "suprasellar" cysts. Cushing introduced the term "craniopharyngioma" for these lesions, which he believed represented one of the most baffling problems faced by neurosurgeons. The patient who most influenced Cushing's thinking was a 16-year-old seamstress named "Mary D.," whom he attended in December 1901, exactly the same month that Alfred Fröhlich published his seminal article describing an adiposogenital syndrome in a young boy with a pituitary cyst...

Although researchers have discovered that Minnie G. had nearly 50 years of progression-free survival, the absence of her original surgical records have precluded anything more than speculation as to the etiology of her symptoms or the details of her admission. Following IRB approval, and through the courtesy of the Alan Mason Chesney Archives, the microfilm surgical records from the Johns Hopkins Hospital, 1896-1912 were reviewed. Using the surgical number provided in Cushing's publications, the record for Minnie G...

Adrenocortical carcinoma is a rare tumor with an annual incidence of 1 to 2 cases per million people. It is a very aggressive tumor, with a median survival of 28 months, and is slightly more common in women (58.6%) than in men (41.4%). The etiology of disease is still unknown. Most adrenocortical neoplasms are hormone functional. These tumors most commonly produce cortisol (30%), then androgens (20%), estrogens (10%) or aldosterone (2%). The rapid onset of Cushing 's syndrome, with its virilizing features, is characteristic of this cancer...

For the purpose of studying the relation of diversities of basic lesion as well as clinical manifestation to hormonal abnormality in Cushing's syndrome, 12 kinds of steroid hormones was simultaneously measured in plasma by using 2 types of Sephadex LH-20 column chromatography in a total of 30 patients comprosing 28 cases of Cushing's syndrome and 2 cases of adrenocortical carcinoma which had abnormal plasma steroid hormone levels without sign or symptom of Cushing's syndrome. In the group of Cushing's syndrome were included cases of pituitary ACTH-dependent hyperplasia (Hp...
