AI Article Synopsis
- The study analyzed vital signs (systolic blood pressure, heart rate, and modified Glasgow coma scale score) in dogs with brain herniation compared to a control group without it.
- Dogs with brain herniation exhibited significantly higher systolic blood pressure and lower modified Glasgow coma scale scores, indicating a relationship between these factors and brain herniation.
- Identifying these signs early can aid veterinarians in diagnosing brain herniation and implementing timely treatment.
Article Abstract
Objective: To document the admission systolic blood pressure (SBP), heart rate (HR), and modified Glasgow coma scale (MGCS) score in dogs with and without brain herniation and to determine their relationship with brain herniation.
Design: Retrospective study between 2010 and 2019.
Setting: University veterinary teaching hospital.
Animals: Fifty-four client-owned dogs with brain herniation and 40 client-owned dogs as a control group, as determined on magnetic resonance imaging.
Interventions: None.
Measurements And Main Results: SBP, HR, MGCS score, and outcome were extracted from medical records. MGCS score was retrospectively calculated based on initial neurological examination in dogs with adequate available information. Dogs with brain herniation had a significantly higher SBP (P = 0.0078), greater SBP-HR difference (P = 0.0006), and lower MGCS score (P < 0.0001) compared to control dogs. A cutoff value of an SBP ≥ 178 mm Hg, SBP-HR ≥ 60, and MGCS score ≤ 14 each provides a specificity of 90%-98%. A combination of an SBP > 140 mm Hg and HR < 80/min provided 24% sensitivity and 100% specificity to diagnose dogs with brain herniation (P < 0.0001).
Conclusions: A high SBP, a greater difference between SBP and HR, a combination of higher SBP and lower HR, and a low MGCS score were associated with brain herniation in dogs presenting with neurological signs upon admission. Early recognition of these abnormalities may help veterinarians to suspect brain herniation and determine timely treatment.

Impact of lumbar cerebrospinal fluid drainage to control intracranial hypertension in patients with severe traumatic brain injury: a retrospective monocentric cohort.
Crit Care

Trauma Critical Care Unit, Montpellier University Hospital, 34295 Cedex 5, Montpellier, France.
Background: External lumbar drainage (ELD) of cerebrospinal fluid may help control intracranial pressure following a traumatic brain injury. We aimed to assess the efficacy and safety of ELD in post-traumatic intracranial hypertension (IH).
Methods: This retrospective monocentric cohort study was conducted in the trauma critical care unit of the regional Level-I trauma centre between January 2012 and December 2022.

Background/aim: Congenital diaphragmatic hernia (CDH) is a critical condition affecting newborns, which often results in long-term morbidities, including neurodevelopmental delays, which affect cognitive, motor, and behavioral functions. These delays are believed to stem from prenatal and postnatal factors, such as impaired lung development and chronic hypoxia, which disrupt normal brain growth. Understanding the underlying mechanisms of these neurodevelopmental impairments is crucial for improving prognosis and patient outcomes, particularly as advances in treatments like ECMO have increased survival rates but also pose additional risks for neurodevelopment.

Patients with complex diseases are mostly treated in a multidisciplinary setting. The impact of multidisciplinary care cannot be emphasized enough as it has the potential to significantly increase survival and, in some cases, help avoid a risky treatment approach. The aim of this case illustration is to emphasize the importance of multidisciplinary treatment and learn from the different approaches that can be made while treating such patients.

Introduction: Ischaemic stroke, primarily caused by thromboembolic events, typically arises as a consequence of underlying vascular or cardiac pathology. Non-thrombotic embolic strokes, although rare, are increasingly seen in interventional and intravascular procedures. Oxygen-ozone therapy (OOT) is one of the popular treatments for lumbar disc herniation, providing pain relief.

Deterioration of a patient's state of consciousness is among the most concerning signs encountered in clinical practice. The evaluation of this finding carries a broad initial differential diagnosis and must account for any relevant medical history. We describe the case of a 41-year-old male with known retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations (RVCL-S) who presented with progressive mental status decline and acute onset intractable headache.
