Cushing syndrome (CS) is a constellation of signs and symptoms caused by excessive exposure to exogenous or endogenous glucocorticoid hormones. Endogenous CS is caused by increased cortisol production by one or both adrenal glands (adrenal CS) or by elevated adrenocorticotropic hormone (ACTH) secretion from a pituitary tumour (Cushing disease (CD)) or non-pituitary tumour (ectopic ACTH secretion), which stimulates excessive cortisol production. CS is associated with severe multisystem morbidity, including impaired cardiovascular and metabolic function, infections and neuropsychiatric disorders, which notably reduce quality of life.

It is well established that maternal factors can affect the abilities of offspring to cope with stressors and can influence their overall welfare states. However, maternal effects have not been extensively explored in US commercial breeding kennels (CBKs). Therefore, the objective of this study was to identify if fear and stress in dams affected puppy welfare metrics in CBKs.

Cushing syndrome due to ectopic adrenocorticotropic hormone (ACTH) secretion (EAS) is rare and may progress rapidly, making treatment very challenging. We report a 27-year-old woman with metastatic neuroendocrine tumor (NET) who presented with sudden onset and rapidly progressing fatigue, muscle weakness, and weight gain. Laboratory findings confirmed severe EAS with new onset hypocalcemia, hypokalemia, and hyperglycemia.

Objective: To determine the prevalence of septo-optic-dysplasia (SOD) in patients with prenatally identified absent cavum septi pellucidi (CSP), agenesis of the corpus callosum (ACC) or dysgenesis of the corpus callosum (DCC).
Study Design: This retrospective chart review investigated neonates prenatally diagnosed with an absent CSP, ACC, or DCC who were admitted to a single quaternary academic medical center in the Pacific Northwest between 2016-2023. This prenatal diagnosis prompted a routine and protocolized postnatal workup for SOD including laboratory evaluation, imaging, and specialty consultation.
Introduction Retinopathy of prematurity (ROP) is a leading cause of preventable childhood blindness. We investigated the association of early postnatal low-dose intravenous hydrocortisone used for the prevention of bronchopulmonary dysplasia (BPD) with ROP-outcome among extremely preterm infants in a Swedish cohort. Methods This retrospective cohort study included extremely preterm infants born before 28 weeks of gestational age (GA).
