Pituitary surgery and COVID.

An effect of the COVID-19 pandemic was the disruption of healthcare systems, especially surgical services provided to the community. Pituitary surgery was especially impacted, given the majority of cases were deemed non-urgent with very few exceptions, and the high risk of viral transmission conferred by the endoscopic endonasal transsphenoidal approach. Patients suffering from pituitary lesions with resultant endocrinopathy or visual symptoms saw their treatment delayed or altered, which had implications on their outcomes and care.

Neuroradiological features of contrast-induced neurotoxicity: A systematic review and pooled analysis.

Background: Contrast-induced neurotoxicity (CIN), is an increasingly recognised complication of endovascular procedures, presenting as a spectrum of neurological symptoms that mimic ischaemic stroke. The diagnosis of CIN remains a clinical challenge, and stereotypical imaging findings are not established. This study was conducted to characterise the neuroimaging findings in patients with CIN, to raise diagnostic awareness and improve decision making.

Tension Pneumocephalus Secondary to Positive Pressure Ventilation Following Endoscopic Endonasal Skull Base Surgery: Three-Year Follow-Up After Implementation of an Institutional Protocol.

Background: Tension pneumocephalus (PMC) is a rare and feared complication following the endonasal endoscopic approach (EEA) to skull base procedures. This is a neurosurgical emergency that requires urgent decompression to avoid catastrophic neurologic damage or death. An avoidable cause is the application of positive pressure ventilation (PPV) in EEA patients for postoperative hypoxia.

Headache Improvement Following Endoscopic Resection of Pituitary Adenomas.

Background: Headache is a common symptom in patients with pituitary adenomas. Research on whether resection of pituitary adenomas via the endoscopic endonasal approach (EEA) affects headaches is limited, and the pathophysiology of headaches associated with pituitary adenomas remains unclear. This study aimed to determine if resection of pituitary adenomas via the EEA improves headaches and investigate factors that may be associated with headaches in patients with pituitary adenoma.

Glucocorticoids and Water Balance: Implications for Hyponatremia Management and Pituitary Surgery.

Water balance is fundamental to all homeostasis. The hypothalamic-pituitary-adrenal axis influences water balance through the effects of corticotropin-releasing hormone and cortisol on arginine vasopressin secretion and the peripheral effects of cortisol on hemodynamics and renal water handling. In this review, we explored the complex interplay of glucocorticoids with water balance, with particular attention to hyponatremia and pituitary surgery.
