Incidental adrenal masses are frequently detected due to the extensive use of cross-sectional imaging, with about 3% to 7% of adults estimated to have them. Paragangliomas and pheochromocytomas (PPGL), rare tumors originating from paraganglia tissues, including the adrenal medulla, continue to be imaging mimics, necessitating a multimodal approach for accurate diagnosis. We report a case of 72-years male presenting with intermittent pain abdomen for the past 1 year.

Associations between hypothalamic-pituitary-adrenal (HPA) axis hormone levels, major depression features and antidepressant effects of ketamine.

Background: Subanesthetic doses of (R,S)-ketamine (ketamine) have demonstrated rapid and robust antidepressant effects in individuals with depression. However, individual variability in response to ketamine exists, and current biomarkers of ketamine treatment response are not entirely understood. Preclinical evidence suggests a link between hypothalamic-pituitary-adrenal (HPA) axis activation, a determinant of the stress response system, and ketamine's efficacy in stressed mice exhibiting enhanced antidepressant responses.

Article Synopsis
  • The study investigates sleep health in children and adolescents with congenital adrenal hyperplasia (CAH) using wrist actigraphy and sleep questionnaires.
  • It found that these children had poorer sleep duration, efficiency, and more awakenings compared to healthy peers, particularly related to hydrocortisone medication timing.
  • The results indicate that sleep issues are significant for children with CAH, highlighting the need for attention in clinical practice and further research.

Introduction: Differentiating pheochromocytomas from other adrenal masses based on computed tomography (CT) characteristics remains challenging, particularly in lipid-poor lesions with variable washout patterns. This study evaluated CT features for distinguishing pheochromocytomas in good and poor washout subcohorts.

Methods: We prospectively analyzed 72 patients with unilateral lipid-poor adrenal masses.
