Here we present, to the best of our knowledge, the first case of a paraneoplastic Cushing's syndrome (hypercortisolism) resulting from treatment-related neuroendocrine prostate cancer - a highly aggressive and difficult disease to treat. A 51-year-old man was started on androgen deprivation therapy after presenting with metastatic prostate cancer, characterized by diffuse osseous metastasis. Shortly thereafter, he developed progressive disease with biopsy proven neuroendocrine prostate cancer as well as symptoms of increased skin pigmentation, hypokalemia, hypertension, hyperglycemia and profound weakness, consistent with ectopic Cushing's syndrome...

An emerging branch of research is examining the linkage between Vitamin D and nonskeletal disorders, including endocrine diseases. In this regard, a still little studied aspect concerns the involvement of vitamin D in adrenal gland disorders. Adrenal gland disorders, which might be theoretically affected by vitamin D unbalance, include adrenal insufficiency, Cushing's syndrome, adrenocortical tumors and hyperaldosteronism. In this review, we provide an updated document, which tries to collect and discuss the limited evidence to be found in the literature about the relationship between vitamin D and adrenal disorders...

OBJECTIVES: To evaluate the safety and long-term efficacy of computed tomography-guided percutaneous ethanol ablation for benign primary and secondary hyperfunctioning adrenal disorders. METHOD: We retrospectively evaluated the long-term results of nine patients treated with computed tomography-guided percutaneous ethanol ablation: eight subjects who presented with primary adrenal disorders, such as pheochromocytoma, primary macronodular adrenal hyperplasia and aldosterone-producing adenoma, and one subject with Cushing disease refractory to conventional treatment...

OBJECTIVE: To investigate the incidence of Cushing's syndrome (CS) in patients with significant hypercortisoluria and the performance of urinary free cortisol (UFC) screening. DESIGN: Retrospective file review. METHODS: The computerized database of a publicly funded health maintenance organization (HMO) in Israel was searched for all patients who underwent 24-hour UFC testing in 2005-2014 with a result of more than twice the upper limit of normal (ULN)...

Chronic exposure to supraphysiologic levels of glucocorticoids (GCs) is associated with impaired bone mineral density, an increase in fracture rates, and, in growing children, compromised linear growth. GCs inhibit bone formation in part by decreasing the number of osteoblasts and by increasing bone resorption by stimulating osteoclasts. While GCs are used to treat many chronic diseases, it is difficult to isolate the effects of the steroids on the bone from the effects of the underlying disease itself. Investigation into the effects of GC exposure on the bone in endogenous Cushing syndrome have contributed to our understanding of bone microarchitecture, growth, healing, and regeneration...

OBJECTIVE: To use magnetic resonance imaging (MRI) to assess the extent of mastoid opacification after canal wall up (CWU) cholesteatoma surgery. MATERIALS AND METHODS: Thirty-five children in whom post-operative MRI had been obtained after CWU surgery. Cholesteatoma confined to the meso- and/or epi-tympanum was removed using a transcanal approach (n=18). More extensive disease required a combined approach tympanomastoidectomy (CAT, n=17). Mastoid opacification was assessed in both ears by a neuroradiologist blind to surgical details using an ordinal scale from 0 (no opacification) to 6 (completely opacified)...

Secreting pituitary adenomas that cause acromegaly and Cushing's disease, as well as prolactinomas and thyrotroph adenomas, are uncommon, usually benign, slow-growing tumours. The rarity of these conditions means that their diagnosis is not familiar to most non-specialist physicians. Consequently, pituitary adenomas may be overlooked and remain untreated, and affected individuals may develop serious comorbidities that reduce their quality of life and life expectancy. Because many signs and symptoms of pituitary adenomas overlap with those of other, more common disorders, general practitioners and non-endocrinology specialists need to be aware of the "red flags" suggestive of these conditions...

We recently demonstrated that the orphan nuclear receptor testicular receptor 4 (TR4) is a potent regulator of corticotroph tumor growth and hormone secretion. The Ras/Raf/MEK/ERK pathway is commonly overactivated in human tumors and we have demonstrated that corticotroph tumor TR4 is activated by ERK1/2-mediated phosphorylation. We evaluated effects of MEK-162, a selective, non-ATP-competitive allosteric inhibitor of MEK1/2, on murine and human in vitro and in vivo corticotroph tumor proliferation and adrenocorticotrophic hormone (ACTH) secretion...

Pregnancy in Cushing's syndrome (CS) is extremely rare due to the influence of hypercortisolism on the reproductive axis. Purpose of this study is to investigate whether the etiology of CS in pregnancy determines a different impact on the fetal/newborn and maternal outcomes. We performed a systematic review of cases published in the literature from January 1952 to April 2015 including the words "Cushing AND pregnancy". We included 168 manuscripts containing 220 patients and 263 pregnancies with active CS during pregnancy and with a history of CS but treated and cured hypercortisolism at the time of gestation...

Hypercortisolemia is associated with abdominal adiposity. Prior studies have quantified visceral adipose tissue (VAT) versus subcutaneous adipose tissue (SAT) accumulation as assessed by CT and MRI in patients with pituitary Cushing's disease (1-3) but not of other etiologies. Hormone differences in women with Cushing's syndrome due to pituitary versus adrenal and iatrogenic etiologies, including differences in DHEA production, may affect body composition.

Adrenocorticotrophin (ACTH)-secreting pituitary adenoma, also known as Cushing disease (CD), is rare and causes metabolic syndrome, cardiovascular disease and osteoporosis due to hypercortisolism. However, the molecular pathogenesis of CD is still unclear because of a lack of human cell lines and animal models. Here, we study 106 clinical characteristics and gene expression changes from 118 patients, the largest cohort of CD in a single-center. RNA deep sequencing is used to examine genotypic changes in nine paired female ACTH-secreting pituitary adenomas and adjacent nontumorous pituitary tissues (ANPT)...

Endocrinopathic laminitis (EL) is a vascular condition of the equine hoof resulting in severe lameness with both welfare and economic implications. EL occurs in association with equine metabolic syndrome and equine Cushing's disease. Vascular dysfunction, most commonly due to endothelial dysfunction, is associated with cardiovascular risk in people with metabolic syndrome and Cushing's syndrome. We tested the hypothesis that horses with EL have vascular, specifically endothelial, dysfunction. Healthy horses (n = 6) and horses with EL (n = 6) destined for euthanasia were recruited...

PURPOSE: Pediatric Cushing's disease (CD) is rare and there are limited data on the long-term outcomes. We assessed CD recurrence, body composition, pituitary function and psychiatric comorbidity in a cohort of pediatric CD patients. METHODS: Retrospective review of 21 CD patients, mean age at diagnosis 12.1 years (5.7-17.8), managed in our center between 1986 and 2010. Mean follow-up from definitive treatment was 10.6 years (2.9-27.2). RESULTS: Fifteen patients were in remission following transsphenoidal surgery (TSS) and 5 were in remission following TSS + external pituitary radiotherapy (RT)...

Transsphenoidal surgery (TSS) was introduced into the Republic of Uzbeksistan in 2005, and has been developed there since. The principal center for the management of all pituitary disease is in a single site for a nation of approxiamately 30 million population. Results in the surgery of Cushing's disease (CD) are a marker of surgical technical skill in TSS. All previously published series come from the developed world where sophisticated investigations and management are available. Many of these investigations are not available in Uzbekistan...

CONTEXT: Cushing's disease (CD) has a significant relapse rate after successful transsphenoidal surgery (TSS). Many CD patients respond aberrantly to desmopressin testing (DT). Disappearance of this response post-surgery may suggest complete removal of abnormal corticotrophs and lower possibility of recurrence. OBJECTIVE: The utility of post-operative DT to predict long-term outcome compared to the widely used post-operative cortisol (Cort) level. DESIGN: Retrospective analysis...

We report a 41-year-old man with HIV and a chronic obstructive pulmonary disease, treated for seven months with Fluticasone/Salmeterol and antiretroviral therapy (Lamivudine, Tenofovir, Atazanavir and Ritonavir). While using these medications, the patients developed a Cushing syndrome in a period of five months. After performing laboratory and imaging tests, it was concluded that the most probable cause of the syndrome was the interaction of inhaled steroids with Ritonavir. After discontinuing these medications the syndrome reverted in a period of 8 months...

BACKGROUND: Our study evaluated the perioperative quality of life (QoL) in Cushing's disease (CD) patients, along with correlations between patient variables and cure rate. METHODS: The 36-item Short-Form Health Survey (SF)-36 questionnaire was used to assess perioperative QoL. Patients completed one survey preoperatively and two surveys postoperatively. Retrospective chart review was conducted to collect SF-36 data as well as examine variables including: age, hospital stay, size of tumour, pathological diagnosis, timing of cure, and complication rates...

Recurrence of hypercortisolemia after initial treatment of Cushing's disease (CD) is more common than previously thought, with a third of patients suffering a recurrence over their lifetime. Awareness of this high rate and delayed timeline (sometimes decades) of potential recurrence is critical and patients with CD should be monitored at regular intervals throughout their lives. In this manuscript, we review the complex evaluation needed for defining CD remission versus persistent disease after surgery, and focus on challenges in diagnosing early recurrent hypercortisolemia...
