BACKGROUND: The release of hormones from the adrenal gland is vital in acute and chronic illnesses such as chronic obstructive pulmonary disease (COPD) involving recurrent exacerbations. Using a metabolomic approach, we aim to investigate associations of different adrenal hormone metabolites with short- and long-term mortality in COPD patients. METHODS: We prospectively followed 172 COPD patients (median age 75 years, 62% male) from a previous Swiss multicenter trial...

Solid lesions emerge within diverse tissue environments making their characterization and diagnosis a challenge. With the advent of cancer radiomics, a variety of techniques have been developed to transform images into quantifiable feature sets producing summary statistics that describe the morphology and texture of solid masses. Relying on empirical distribution summaries as well as grey-level co-occurrence statistics, several approaches have been devised to characterize tissue density heterogeneity. This article proposes a novel decision-tree based approach which quantifies the tissue density heterogeneity of a given lesion through its resultant distribution of tree-structured dissimilarity metrics computed with least common ancestor trees under repeated pixel re-sampling...

Glucocorticoid replacement therapy is the mainstay of treatment for congenital adrenal hyperplasia (CAH) but has a narrow therapeutic index and dose optimisation is challenging. Metabolomic profiling was carried out on plasma samples from 117 adults with 21-hydroxylase deficiency receiving their usual glucocorticoid replacement therapy who were part of the CaHASE study. Samples were profiled by using hydrophilic interaction chromatography with high resolution mass spectrometry. The patients were also profiled using nine routine clinical measures...

BACKGROUND: We report a rare case of a juxta-adrenal schwannoma that could not be discriminated from an adrenal tumor before surgical resection and was complicated by bilateral hyperaldosteronism. To the best of our knowledge, this is first case in which both a juxta-adrenal schwannoma and hyperaldosteronism co-existed. CASE PRESENTATION: A 69-year-old male treated for hypertension was found to have a left supra-renal mass (5.8 × 5.2 cm) by abdominal computed tomography...

BACKGROUND: Diagnosis of Cushing syndrome requires a multistep process that includes verification of hypercortisolism followed by identification of the cause of adrenocortical hyperfunction. This study assessed whether pituitary, ectopic, and adrenal subtypes of Cushing syndrome were characterized by distinct plasma steroid profiles that might assist diagnosis. METHODS: In this retrospective cross-sectional study, mass spectrometric measurements of a panel of 15 plasma steroids were applied to 222 patients tested for Cushing syndrome...

The incidence rates of phaeochromocytoma and colorectal cancer (CRC) are approximately 1 and 65 per 100,000 per year, respectively. Simultaneous presentation of these conditions is rare and poses unique management challenges. We report on treatment strategies and clinical outcomes in a series of patients with colorectal neoplasia and phaeochromocytoma. Demographic and clinical details of four patients over a 4-year period were reviewed. The median (range) age at first presentation was 66 (52-70) years. Phaeochromocytoma (2...

Primary aldosteronism (PA) comprises two main subtypes: unilateral aldosteronism, mainly caused by aldosterone-producing adenoma; and bilateral adrenal hyperplasia. Establishing the correct subtype in patients with PA is indispensible for choice of treatment. In addition to established methods, alternative tests are evolving for subtyping. Computed tomography (CT) and adrenal venous sampling (AVS) are currently recommended in the guidelines for the diagnostic work-up of patients with PA. CT cannot be used as a stand-alone test for subtyping because of its limited accuracy but may be used in combination with other tests such as AVS or functional imaging...

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) in pregnancy is associated with gestational diabetes mellitus (GDM). This propensity toward heightened insulin resistance in OSA patients has not been well characterized and may be related to dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. The aim of this study was to (1) assess the prevalence of OSA in pregnant women with GDM, (2) evaluate whether HPA axis dysregulation relates to OSA, and (3) investigate the relation between insulin resistance and OSA...

REVIEW
Kate C Verbeeten, Alexandra H Ahmet
Cortisol is a hydrophobic molecule that is largely bound to corticosteroid-binding globulin (CBG) in the circulation. In the assessment of adrenal insufficiency, many clinicians measure a total serum cortisol level, which assumes that CBG is present in normal concentrations and with a normal binding affinity for cortisol. CBG concentration and affinity are affected by a number of common factors including oral contraceptive pills (OCPs), fever and infection, as well as rare mutations in the serine protease inhibitor A6 (SERPINA6) gene, and as such, total cortisol levels might not be the ideal way to assess adrenal function in all clinical circumstances...

The aim of this study was to investigate the effect of various cooking techniques on the fatty acid and oxylipin content of farmed rainbow trout. Rainbow trout is an excellent source of long-chain omega-3 (n-3) polyunsaturated fatty acids (PUFA) which have beneficial health effects. Fillets of 2-year-old farmed rainbow trout were baked, broiled, microwaved, or pan-fried in corn (CO), canola (CaO), peanut (PO), or high oleic sunflower oil (HOSO). Fatty acids and oxidized lipids were extracted from these samples and their respective raw fillet samples...

Primary bilateral macronodular adrenocortical hyperplasia (PBMAH) is an uncommon cause of adrenal Cushing syndrome (CS) in which cortisol and occasionally other steroid hormones can be secreted under the influence of aberrantly expressed G-protein coupled receptors (GPCRs) in the adrenal cortex. We describe the unique case of a 64-year-old postmenopausal female with PBMAH whose adrenal lesions expressed luteinizing hormone receptors (LHr). She presented initially with CS and underwent right adrenalectomy; a few years later she presented with macromastia and mastodynia, possibly due to estrogen excess from her remaining left adrenocortical masses...

Maxillary sinus cancer is rare, and often presents as a locally advanced disease. Recurrence commonly occurs locoregionally, while fewer patients present with distant metastasis; the most common sites involved are the lung and bone. This report discusses the case of a 64-year-old male who presented with a mass in the left submandibular area. Biopsy was performed and histological analysis identified a poorly differentiated squamous cell carcinoma. After staging work up, it was concluded the patient had a maxillary sinus squamous cell carcinoma at clinical stage IVA...

AIMS: Contrary findings exist on the consistency between hair cortisol and salivary cortisol in assessing the basal activity of the hypothalamic-pituitary-adrenal (HPA) axis. The mismatches in temporal characteristic and the indices of hair and salivary cortisol might be potential reasons for the inconsistency. The aim of this study was to investigate the consistency between hair and salivary levels in cortisol and cortisone by directly examining the correlation between hair level and salivary level with different temporal characteristics (acute, short-term and long-term levels) and reflecting different HPA functions (basal level and reactivity level) in the well-matched time span...

Context: Cushing's syndrome is rarely caused by the secretion of cortisol from the ovarian tumors. It is important to determine whether the ovarian tumor is capable of secreting cortisol or not in clinical decision making. Selective ovarian and adrenal venous sampling has not been reported previously in the localization of ACTH-independent ectopic Cushing's syndrome. Case description: Herein, we presented a case of 40-year-old Chinese woman who has been manifested with weight gain, hirsutism, hypertension and menstrual disorder over a period of 6 months...
