The authors report a case of hypertensive emergency (defined as systolic blood pressure >180 mm Hg and diastolic blood pressure >110 mm Hg with end organ damage) following brachial plexus blockade in a hypertensive lady with unstable angina. The authors describe blocking of baroreceptor reflexes by the local anaesthetic as a putative mechanism and suggest that this potentially serious complication should be considered when planning this particular anaesthetic technique.

Background: Unconsciousness occurs when a patient enters a sleeplike state but cannot be aroused, and it is not due to physiological drowsiness. It is a common presentation in the Accident and Emergency Department (A&E), and a burden to the emergency physician especially when the cause is unknown. The cause of coma may be trauma or non-trauma related.

Anesthesiology, Nihon University School of Medicine, Tokyo, JPN.
Background: Several cases of pheochromocytoma presenting with hypertensive crises after anesthesia induction, possibly caused by rocuronium injection, have been reported. Rocuronium has two compositions: rocuronium bromide (RB) in sodium acetate hydrate/acetic acid buffer solution (acetic acid vehicle) and RB in glycine/hydrochloric acid buffer solution (hydrochloric acid vehicle). This study assessed the effect of rocuronium composition on the release of catecholamine from PC-12 rat adrenal pheochromocytoma cells.

Background: Undiagnosed and untreated atherosclerotic renal artery stenosis (ARAS) can result in end-stage kidney disease (ESKD). To obtain an accurate diagnosis, it is crucial to recognize the symptoms and signs suggesting renal artery stenosis (RAS) and perform appropriate diagnostic and treatment procedures afterward.
Case Presentation: We present a case of a 60-year-old female patient with hypertensive crisis, acute heart failure (HF), and pulmonary edema as the initial signs of acute kidney injury (AKI) caused by right RAS and left renal artery occlusion in the presence of severe aortic atherosclerosis revealed on computed tomography angiography (CTA) of the abdomen.
Autophagy and Mitophagy in Diabetic Kidney Disease-A Literature Review.
Int J Mol Sci

Department of Nephrology, Carol Davila University of Medicine and Pharmacy, 020021 Bucharest, Romania.
Autophagy and mitophagy are critical cellular processes that maintain homeostasis by removing damaged organelles and promoting cellular survival under stress conditions. In the context of diabetic kidney disease, these mechanisms play essential roles in mitigating cellular damage. This review provides an in-depth analysis of the recent literature on the relationship between autophagy, mitophagy, and diabetic kidney disease, highlighting the current state of knowledge, existing research gaps, and potential areas for future investigations.
