RESUMEN
Targeted temperature management (TTM), specifically therapeutic hypothermia, has been proposed to provide neuroprotective and mortality benefits for out-of-hospital cardiac arrest (OHCA) survivors. This proposition was based on small-scale trials from the early 2000s, leading to its incorporation into various international guidelines. The proposed neuroprotective mechanisms include reducing cerebral metabolic rate, stabilizing the blood-brain barrier, reducing the release of excitatory neurotransmitters, and suppressing apoptotic pathways. However, these early trials have been criticized for their high risk of bias and lack of standardized protocols. Recent evidence from more rigorously controlled randomized trials indicates no significant association between hypothermia and improved neurological outcomes or survival rates. This review explores the latest clinical evidence on TTM for OHCA patients, discussing the pathophysiology, evaluating the effectiveness of hypothermia through various clinical trials, and providing recommendations for future research and clinical practice.
RESUMEN
An acute abdomen that is tender to palpation often represents a life-threatening emergency requiring immediate surgical or medical management. We present a case of acute abdomen with peritoneal signs and symptoms due to epiploic appendagitis (EA) that resolved with a single dose of ibuprofen. EA often mimics appendicitis, diverticulitis, and rarely cholecystitis based on its location. It arises due to ischemic infarction of an epiploic appendage, typically caused by torsion or spontaneous thrombosis of the central draining vein. Despite its rarity, clinicians need to recognize the characteristic imaging findings of EA on CT and ultrasound to avoid unnecessary surgical interventions and to manage the condition conservatively.
