Context: Adrenal incidentalomas (AIs) are found commonly on axial imaging. Around 30% exhibit autonomous cortisol secretion (ACS) associated with increased cardiovascular events and death. Objective: We hypothesized that AI/ACS patients have an abnormal cortisol rhythm that could be reversed by use of carefully timed short-acting cortisol synthesis blockade, with improvement in cardiovascular disease markers. Design, Setting, and Participants: In a phase 1/2a, prospective study (Eudract no...

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare malignancy, with an annual incidence of 1 or 2 cases per million. Biochemical diagnosis is challenging because up to two-thirds of the carcinomas are biochemically silent, resulting from de facto enzyme deficiencies in steroid hormone biosynthesis. Urine steroid profiling by GC-MS is an effective diagnostic test for ACC because of its capacity to detect and quantify the increased metabolites of steroid pathway synthetic intermediates...

BACKGROUND: Preterm birth is a stressful event for both the mother and infant. Whereas the initiation of breastfeeding is important for preterm infant health, little is known of the glucocorticoid hormones (cortisol and cortisone) in human milk following preterm birth. Research aim: The aim of this study was to investigate the relationship between human milk glucocorticoid concentrations and preterm birth. METHODS: Human milk was sampled weekly for up to 6 weeks from 22 women who delivered a preterm infant at 28 to 32 weeks' gestation...

The bone marrow basically consists of red blood-forming bone marrow and yellow fat. In the skeleton, there is an age-dependent distribution of these two parts. In the context of medical interventions or therapies, bone marrow changes can occur, whereby the normal bone marrow can basically be replaced by fat, edema, or fibrosis/sclerosis. Here, specific signal intensities and patterns are shown in imaging. After irradiation therapies, edematous changes, hemorrhages, and osteoradionecroses are observed. Likewise, insufficiency fractures, impairment of the growth gaps, or the development of tumors is possible...

Dry eye syndrome (DES) is a disorder of the eye due to tear deficiency or excessive evaporation that causes damage to the eye and is associated with discomfort and dryness. 11β-Hydroxysteroid dehydrogenase 1 (11β-HSD1) is an enzyme that converts inactive cortisone to active cortisol. Recently, 11β-HSD1 has been expressed in human and rodent eyes and has been recognized as a target of glaucoma. In this study, the therapeutic effects and underlying mechanisms of topical carbenoxolone, an 11β-HSD1 inhibitor, were investigated in benzalkonium chloride (BAC)-treated human conjunctival epithelial cells and a rat DES model...

Salivary markers have been proposed as noninvasive and easy-to-collect indicators of dehydrations during physical exercise. It has been demonstrated that threshold-based classifications can distinguish dehydrated from euhydrated subjects. However, considerable challenges were reported simultaneously, for example, high intersubject variabilities in these markers. Therefore, we propose a machine-learning approach to handle the intersubject variabilities and to advance from binary classifications to quantitative estimations of total body water (TBW) loss...

Glucocorticoids are vital for lung maturation. We previously showed that cortisol is lower in obese pregnancy. Whether this is maintained at delivery is unknown but is clinically relevant as maternal and cord blood cortisol levels are correlated and offspring of obese are more likely to need neonatal respiratory support. We hypothesized that glucocorticoids are lower in maternal and cord blood at delivery in obese pregnancies. Glucocorticoids (cortisol and corticosterone) and their inactive versions (cortisone and 11-dehydrocorticosterone) were measured by LC-MS/MS in maternal and cord plasma from 259 Caucasian women at delivery (BMI 18-55 kg/m(2))...

BACKGROUND: Flexor tendon ruptures in the wrist are uncommon. Flexor carpi radialis (FCR) tendon rupture can occur in rheumatoid patients, following cortisone injection for tenosynovitis, and following trauma. Following tendon rupture, tethering of the ruptured FCR tendon, or pseudotendon, can form which may or may not be symptomatic. METHODS: A literature review was done reviewing treatment and outcomes of FCR tendon lesions. A case report of painful FCR pseudotendon following a fall is presented...

PURPOSE: Patients with growth hormone deficiency (GHD) demonstrate an increased cortisol/cortisone ratio which could potentially explain the metabolic features of GHD, while GH treatment (GHT) could increase the cortisol metabolism. METHODS: In 35 children (27 M, mean age 10.1 years) with idiopathic GHD at baseline and after 12 months of GHT and in 25 controls, in addition to metabolic parameters, we assessed adrenal function by morning serum cortisol, its peak, and its area under the curve (AUCCOR) during insulin tolerance test (ITT)...

BACKGROUND: Late-night salivary cortisol level is one of the first-line tests recommended by the Endocrine Society for the diagnosis of endogenous hypercortisolism. Most routine laboratories measure cortisol levels using immunoassay tests which fail to determine low cortisol levels accurately due to the numerous interfering substances. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method with simple and rapid sample preparation was developed for the simultaneous measurement of cortisol and cortisone and its performance in the diagnosis of endogenous hypercortisolism was evaluated...

BACKGROUND: Exposure to ambient particulate matter (PM) is associated with a number of adverse health outcomes, but potential mechanisms are largely unknown. Metabolomics represents a powerful approach to study global metabolic changes in response to environmental exposures. We therefore conducted this study to investigate changes in serum metabolites in response to the reduction of PM exposure among healthy college students. METHODS: We conducted a randomized, double-blind crossover trial in 55 healthy college students in Shanghai, China...

The acute urge to be physically active is a relevant clinical phenomenon in patients suffering from eating disorders. In this study with n = 20 female patients with anorexia nervosa and n = 10 female patients with bulimia nervosa, a virtual reality (VR) jogging paradigm was applied as a novel highly immersive 3-D exposure paradigm. Patients were asked to rate their acute urge to be physically active during the exposure procedure. A 10-item self-report questionnaire (smQ) was developed to capture the cognitive, emotional, and behavioral aspects of the acute urge to move...

We observed a case over 25 years of relapsing-remitting schizophrenic spectrum disorder, varying regarding the main symptomatology between more depressive or more schizoaffective or rather typical schizophrenic syndrome. Diseased phases were repeatedly accompanied by minor skin lesions, which were initially classified as mixed tissue disorder. Psychotic phases were waxing-waning over years. During one later relapse, skin involvement was severe, classified to likely represent an allergic reaction to psychopharmaca; this generalized exanthema remitted rapidly with cortisone treatment and azathioprine...

BACKGROUND: Recent studies have shown that production of cortisol not only takes place in several non-adrenal peripheral tissues such as epithelial cells but, also, the local inter-conversion between cortisone and cortisol is regulated by the 11β-hydroxysteroid dehydrogenases (11β-HSDs). However, little is known about the activity of this non-adrenal glucocorticoid system in cancers. METHODS: The presence of a functioning glucocorticoid system was assessed in human skin squamous cell carcinoma (SCC) and melanoma and further, in 16 epithelial cell lines from 8 different tissue types using ELISA, western blotting and immunofluorescence...

BACKGROUND: Sun irradiation is one of major extrinsic stressors responsible for premature skin aging through activation and expression of 11 beta-hydroxysteroid dehydrogenase type 1 (11β-HSD1), which converts inactive cortisone to active cortisol. The aim of this study was to evaluate the inhibitory effects of red ginseng extract containing high concentrations of ginsenoside Rg3 (S) (GERg3) on 11β-HSD1-induced skin photoaging. METHODS: To evaluate the inhibitory effects of GERg3 on ultraviolet- (UV) or infrared (IR)-induced skin photoaging, human dermal fibroblasts or a normal human 3D skin model was exposed to UV or an IR...

Burnout is a syndrome with negative impact on cognitive performance and mood as a consequence of long-term stress at work. It is further associated with increased risk for mental and physical diseases. One potential pathway to mediate chronic work-stress and adverse health conditions in burnout is through alterations in long-term glucocorticoid secretion. Here, we present cross-sectional data on hair cortisol/cortisone (hairF/hairE) concentrations and burnout from a population-based sample of the Dresden Burnout Study (DBS; N=314 hair samples)...

OBJECTIVE: Mitotane, a drug used to treat adrenocortical cancer (ACC), inhibits multiple enzymatic steps of adrenocortical steroid biosynthesis, potentially causing adrenal insufficiency. Recent studies in vitro have also documented a direct inhibitory effect of mitotane at the pituitary level. The present study was aimed to assess the hypothalamic pituitary adrenal axis in ACC patients receiving mitotane. DESIGN AND METHODS: We prospectively enrolled 16 patients on adjuvant treatment with mitotane after radical surgical resection of ACC, who underwent standard hormone evaluation and h-CRH stimulation...

Studies in rodents highlight a role for leptin in stimulation of pituitary growth hormone (GH) secretion, with an impact on body composition regulation. We have reported that maternal obesity (MO) during ovine pregnancy results in hyperphagia, glucose-insulin dysregulation, increased adiposity, hypercortisolemia and hyperleptinemia in mature offspring subjected to a bout of ad libitum feeding. We hypothesized that MO reduces leptin signaling in the pituitary and down regulates the GH/IGF1 axis and increases circulating cortisol leading to increased adiposity in their adult offspring...

Physicians' daily work is accompanied by emotional and physical stress, and 24-h shifts are considered to be a major stressor. Effects of stressors on the hypothalamic-pituitary-adrenal (HPA) axis can be evaluated by estimating the glucocorticoid excretion in urine samples. We characterized the impact of a 24-h working period on the urinary glucocorticoid excretion of physicians and focused on gender differences. 10 females and 12 male physicians collected 24-h urine samples during a 24-h shift ("on-duty") and on a free weekend ("off-duty") that were analyzed by gas chromatography-mass spectrometry...
