Hypokalemia and hypomagnesemia are frequently observed in patients with chronic alcoholism. However, the involvement of deranged cortisol regulation in patients with those conditions has not been reported. A 63-year-old Japanese male with chronic alcoholism was referred to the Department of Diabetes, Endocrinology and Metabolism for examination and treatment of hypokalemic periodic paralysis. Laboratory findings showed hypokalemia (2.3 mmol/l), as well as a high level of urinary excretion of potassium and hypomagnesemia (1...

Rohan R Joshi, Alison Maresh
The use of intranasal steroid drops for nasal obstruction in infants is common practice and can prevent more invasive surgical procedures; however, it is not without complication. We describe 2 cases of iatrogenic Cushing's secondary to nasal steroids in infants with nasal obstruction, discuss the etiology of this unusual complication, and review previous literature reports. While reporting in the literature is sparse, these cases highlight the risk of development of adrenal insufficiency with usage of nasal steroid drops in infants as well as the need for close monitoring of administration and tapering of the drops...

Both congenital and acquired fibrinogen deficiency can be safely treated with administration of fibrinogen concentrate. The aim of this study was to test the efficacy of a new fibrinogen product (Fibryga) compared to a licensed product (Haemocomplettan) in an in vitro model of dilutional coagulopathy. Ten blood specimens from healthy volunteers were diluted 1:1 with balanced crystalloid solution and subsequently supplemented with each fibrinogen concentrate at a dose replicating in vivo supplementation (50 mg kg -1 )...

Recently discovered mutations of NR3C1 gene, encoding for the Glucocorticoid Receptor (GR), in patients with glucocorticoid resistance and bilateral adrenal incidentalomas prompted us to investigate whether GR mutations might be associated with adrenal hyperplasia. OBJECTIVE: The multicenter French Clinical Research Program (Muta-GR) was set up to determine the prevalence of GR mutations and polymorphisms in patients harboring bilateral adrenal incidentalomas associated with hypertension and/or biological hypercortisolism without clinical Cushing's signs...

Pregnancy in women with a diagnosis of Cushing' syndrome (CS) is an extremely rare event and its diagnosis and treatment are a real medical challenge. During pregnancy, the hypothalamus-pituitary-adrenal axis undergoes major changes leading to a significant increase in plasma cortisol levels throughout gestation. The difficulties in diagnosis are related to the resemblance of symptoms of CS and those of pregnancy, and to the complex interpretation of the screening tests. Moreover, the diagnostic work up in the postnatal period may be difficult in the first weeks postpartum...

BACKGROUND: Surgery is the definitive treatment of Cushing's syndrome (CS) but medications may also be used as a first-line therapy. Whether preoperative medical treatment (PMT) affects postoperative outcome remains controversial. OBJECTIVE: 1) Evaluate how frequently PMT is given to CS patients across Europe 2) examine differences in preoperative characteristics of patients who receive PMT and those who undergo primary surgery; 3) determine if PMT influences postoperative outcome in pituitary-dependent CS (PIT-CS)...

CONTEXT: Bilateral inferior petrosal sinus sampling (BIPSS) using hCRH is currently considered the 'gold standard' test for the differential diagnosis of ACTH-dependent Cushing's syndrome (CS). Vasopressin is more potent than CRH to stimulate ACTH secretion as shown in animal studies, however; no comparative data of its use is available during BIPSS. OBJECTIVE: To study the diagnostic accuracy and comparison of hCRH and lysine vasopressin (LVP) stimulation during BIPSS...

OBJECTIVE: MMP-9, PTTG, and HMGA2 play important roles in the tumorigenesis of adrenocorticotrophic hormone (ACTH)-secreting pituitary tumors, but their associations with tumor recurrence after transsphenoidal adenomectomy remain unclear. The aim of the study was to investigate the immunohistochemical expression profiles of MMP-9, PTTG, HMGA2, and Ki-67 in recurrent and non-recurrent ACTH-secreting pituitary tumors and to identify their associations with tumor behavior and recurrence status...

Fearful faces convey threat cues whose meaning is contextualized by eye gaze: While averted gaze is congruent with facial fear (both signal avoidance), direct gaze (an approach signal) is incongruent with it. We have previously shown using fMRI that the amygdala is engaged more strongly by fear with averted gaze during brief exposures. However, the amygdala also responds more to fear with direct gaze during longer exposures. Here we examined previously unexplored brain oscillatory responses to characterize the neurodynamics and connectivity during brief (~250 ms) and longer (~883 ms) exposures of fearful faces with direct or averted eye gaze...

Oncocytic tumors are epithelial neoplasms that occur in various organs, including adrenal glands. Oncocytic adrenocortical adenomas and carcinomas are uncommon but well-known pathological entities in adults. However, generally oncocytic tumors, particularly in the adrenal glands, are very rare in the pediatric age-group. Most oncocytic adrenal tumors are not functional. We present a rare case of right-sided, functional oncocytic adrenocortical adenoma in a 5-year-old boy, who presented with clinical manifestations of precocious puberty and Cushing syndrome...

INTRODUCTION: Hormonal insufficiency of one or more pituitary axes can appear after pituitary surgery. Adrenal axis impairment after surgery can lead to serious consequences if not identified and treated. OBJECTIVE: Assess early and late post-operative adrenal insufficiency (AI) and identify the risk factors predicting their occurrence after endoscopic transsphenoidal resection of pituitary adenomas. METHOD: Retrospective review identified 176 pituitary adenomas resected using an endoscopic transsphenoidal approach...

Introduction: Among veterans of post-9/11 conflicts, estimates of post-traumatic stress disorder (PTSD) range from 9% shortly after returning from deployment to 31% a year after deployment. Clinical and pharmaceutically based treatments are underutilized. This could be due to concerns related to lost duty days, as well as PTSD patients' fears of stigma of having a mental health condition. Yoga has been shown to reduce PTSD symptoms in the civilian population, but few studies have tested the impact of yoga on veterans of post-9/11 conflicts...

Oliver D Mrowczynski, Sara T Langan, Elias B Rizk
Cushing once described craniopharyngiomas as the most forbidding tumor; and, despite surgical advances decades later, craniopharyngioma resection is still extremely complex due to its location and infiltration into local structures, making gross total resection challenging. Adjuvant treatments include radiation and chemotherapy, but intratumoral therapy may emerge as an adjuvant treatment for craniopharyngiomas. Here, we present a review of the literature on this treatment modality; and, summarize the available reported cases to underline usefulness and effectiveness of this treatment method...

REVIEW
Christina Tatsi, Constantine A Stratakis
Neonatal Cushing syndrome (CS) is most commonly caused by exogenous administration of glucocorticoids and rarely by endogenous hypercortisolemia. CS owing to adrenal lesions is the most common cause of endogenous CS in neonates and infants, and adrenocortical tumors (ACTs) represent most cases. Many ACTs develop in the context of a TP53 gene mutation, which causes Li-Fraumeni syndrome. More rarely, neonatal CS presents as part of other syndromes such as McCune-Albright syndrome or Beckwith-Wiedemann syndrome...

For structured populations with an annual breeding season, life-stage interactions and behavioral tactics may occur on a faster time scale than that of population dynamics. Motivated by recent field studies of the effect of rising sea surface temperature (SST) on within-breeding-season behaviors in colonial seabirds, we formulate and analyze a general class of discrete-time matrix models designed to account for changes in behavioral tactics within the breeding season and their dynamic consequences at the population level across breeding seasons...

PURPOSE: To evaluate the effect of pasireotide on β-cell and adipose function in patients with Cushing's disease (CD). METHODS: Clinical and hormonal parameters, insulin secretion evaluated by HOMA-β and by the area under the curve (AUC2h) of C-peptide during a mixed meal tolerance test and insulin sensitivity, evaluated by the euglycaemic hyperinsulinaemic clamp, were evaluated in 12 patients with active CD, before and after 6 and 12 months of pasireotide. In addition, a panel of adipokines including leptin (Ob), leptin/leptin receptor ratio (Ob/Ob-R ratio), adiponectin, resistin, visfatin, adipocyte fatty acid binding protein (AFABP) and non-esterified fatty acids (NEFAs) was evaluated at baseline and after 12 months of pasireotide...

REVIEW
N Reisch, M Reincke
Endocrine paraneoplastic syndromes result from the production of bioactive substances from neoplastic cells, of endocrine or neuroendocrine origin. Typically these are located in the lungs, the gastrointestinal tract, pancreas, thyroid gland, adrenal medulla, skin, prostate or breast. In endocrine paraneoplastic syndromes the secretion of peptides, amines or other bioactive substances is always ectopic and not related to the anatomical source. The clinical presentation, however, is indistinguishable from a suspected eutopic endocrine tumor posing a diagnostic challenge...

RATIONALE: Adrenal myelolipomas are rare benign tumors, composed of a variable mixture of mature adipose tissue and hematopoietic tissue. These tumors are frequently detected incidentally and are usually asymptomatic, and hormonally inactive. PATIENT CONCERNS: During a routine health checkup, a 52-year-old man was found to have a tumor on the bilateral adrenal glands. Abdominal computed tomography revealed a well-defined, heterogeneously enhanced bilateral adrenal mass, suggesting a myelolipoma...

PURPOSE: Patients with Cushing's disease (CD) experience metabolic alterations leading to increased cardiovascular mortality. Recently, the visceral adiposity index (VAI) has been proposed as a marker of visceral adipose tissue dysfunction (ATD) and of the related cardiometabolic risk. We aimed to evaluate the impact of 12-month pasireotide treatment on cardiometabolic risk in CD patients. METHODS: This is a multicentre, prospective, and observational study. Sixteen CD patients, referred to the Endocrine Units of the University Hospitals of Messina, Napoli, Padova, and Palermo (Italy), successfully treated with pasireotide for 12 month have been enrolled...
