AI Article Synopsis
Article Abstract
This is a case report of a 64-year-old man with pulmonary sarcoidosis also affecting the joints. He was admitted to an emergency department following 21 days of fatigue, visual disturbances and headache. Initial blood tests revealed hypothalamic-pituitary dysfunction including acute adrenal insufficiency, and an MRI scan of the cerebrum showed a neurosarcoidosis tumour involving the hypothalamus-pituitary gland. Neurosarcoidosis is a condition with widespread clinical variation and early, and correct diagnosis is important.

The effects of lowering barometric pressure on pain behavior and the stress hormone in mice with neuropathic pain.

Background: Lowering barometric pressure (LP) can exacerbate neuropathic pain. However, animal studies in this field are limited to a few conditions. Furthermore, although sympathetic involvement has been reported as a possible mechanism, whether the sympathetic nervous system is involved in the hypothalamic-pituitary-adrenal (HPA) axis remains unknown.

Chronic stress and stress-related mental illnesses such as major depressive disorder (MDD) constitute some of the leading causes of disability worldwide with a higher prevalence in women compared to men. However, preclinical research into stress and MDD is heavily biased toward using male animals only. Aberrant activity of the hypothalamic-pituitary-adrenal (HPA) axis has been linked to the development of MDD and several animal models of MDD have been established based on HPA axis dysregulation.

Clin Transl Radiat Oncol
March 2025
Department of Radiation Oncology (Maastro), GROW Research Institute for Oncology and Reproduction, Maastricht University Medical Centre+, Maastricht, the Netherlands.
Background And Purpose: Radiotherapy for brain, head & neck (HN), and skull base (SB) tumors may deliver significant radiation dose to the hypothalamic-pituitary axis (HPA), leading to impaired functioning of this region and hence, to endocrine disorders. The purpose of this systematic review and -analysis is to investigate literature on HP dysfunction after radiation for non-pituitary brain, HN, or SB tumors at adult age, aiming to give insight in the prevalence of HP dysfunction related to radiation dose.
Materials And Methods: Literature search of the PubMed database was performed for HP dysfunction after radiotherapy in adult patients.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects women of reproductive age and is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. PCOS is often associated with hormonal imbalances, metabolic dysfunction and comorbid psychiatric disorders, including eating disorders (EDs). The review identifies key hormonal factors-serotonin, leptin, insulin, ghrelin, kisspeptin and cortisol-and their roles in the pathophysiology of PCOS and associated psychiatric symptoms.

Chronic stress exposure has been widely recognized as a significant contributor to numerous central nervous system (CNS) disorders, leading to debilitating behavioral changes such as anxiety, depression, and cognitive impairments. The prolonged activation of the hypothalamic-pituitary-adrenal (HPA) axis during chronic stress disrupts the neuroendocrine balance and has detrimental effects on neuronal function and survival.
