Retrospective Observational Study of Patients With Subdural Hematoma Treated With Idarucizumab.

Use of anticoagulants is increasing with the aging of societies. The safe first-line drug is likely to be a direct oral anticoagulant (DOAC), but outcomes of treatment of traumatic brain injury (TBI) with anticoagulants are uncertain. Therefore, we examined the clinical effect of idarucizumab as reversal therapy in elderly patients with TBI who were treated with dabigatran.

Hyperhomocysteinemia as a Cause of Acute Ischemic Stroke in a Four-Year-Old Child: A Report of a Rare Case.

Homocysteine is a type of amino acid that isn't genetically encoded by the human body. This amino acid is capable of causing oxidative damage to the endothelial cells, leading to the onset of thrombosis. Moreover, it can also inflict harm to neurons by activating pro-apoptotic factors, causing DNA damage, and inducing oxidative stress, as observed in various animal models and cell cultures.

Outcome of Nonoperative Management of Selected Cases of Acute Traumatic Intracranial Hematomas in a Rural Neurosurgical Service of a Developing Country.

Objective: In resource-limited settings, the standard of care prescribed in developed countries for either operative or nonoperative management of traumatic intracranial hematomas (TICHs) frequently has to be adapted to the economic and infrastructural realities. This study aims to present the outcome of selected cases of TICHs managed nonoperatively without routine intensive care unit admission, repeated cranial computed tomography (CT) scan or intracranial pressure monitoring at a rural neurosurgical service in a developing country.

Methods: This was a retrospective analysis of a cohort of our patients with cranial CT-confirmed TICHs selected for nonoperative treatment from our prospective head injury (HI) register over a 42-month period.

Ruptured brainstem arteriovenous malformation associated with a thalamoperforating artery aneurysm arising from the P1 segment of the right posterior cerebral artery: illustrative case.

Background: Cerebral aneurysms of perforating arteries are rare and can be difficult to detect on computed tomography angiography (CTA) and digital subtraction angiography. Treatment is challenging and associated with a significant risk of morbidity. Endovascular treatment of a thalamoperforating artery (TPA) aneurysm within the midbrain has not previously been reported.

Describing Anisocoria in Neurocritically Ill Patients.

Background: Anisocoria (unequal pupil size) has been defined using cut points ranging from greater than 0.3 mm to greater than 2.0 mm for absolute difference in pupil size.

A retrospective study of structural brain lesions identified by magnetic resonance imaging in 114 cats with neurological signs.

Background And Aim: Magnetic resonance imaging (MRI) has been widely used as a non-invasive modality to evaluate neurological organ structures. However, brain MRI studies in cats with neurological signs are limited. This study evaluated the association between patient characteristics, neurological signs, and brain lesion locations identified by MRI.

AN OUTBREAK OF FELINE INFECTIOUS PERITONITIS IN THREE RELATED SAND CATS () IN HUMAN CARE.

Feline infectious peritonitis (FIP) is a systemic disease in felid species caused by infection with mutated forms of feline coronavirus (FCoV), and outbreaks can devastate exotic felid populations in human care. Feline infectious peritonitis was diagnosed in three of four related juvenile sand cats () from a single institution over a 6-wk period. Case 1 was a 7-mon-old male found deceased with no premonitory signs.

Trigeminal Stimulation and Visuospatial Performance: The Struggle between Chewing and Trigeminal Asymmetries.

Chewing improves visuospatial performance through locus coeruleus (LC) activation. The effects of bilateral and unilateral mastication were investigated in subjects showing different degrees of asymmetry in masseter electromyographic (EMG) activity during clenching and in pupil size at rest (anisocoria), which is a proxy of LC imbalance. Correlations between performance changes and asymmetry values were found in males, but not in females.

Normative Values for Pupillary Light Reflex Metrics Among Healthy Service Academy Cadets.

Introduction: Assessments of the pupil's response to light have long been an integral part of neurologic examinations. More recently, the pupillary light reflex (PLR) has shown promise as a potential biomarker for the diagnosis of mild traumatic brain injury. However, to date, few large-scale normative data are available for comparison and reference, particularly, in military service members.

Sex-related differences in symptom presentation of patients with aneurysmal subarachnoid hemorrhage.

In patients with myocardial infarction, atypical symptoms at onset have been demonstrated in women. We aimed to investigate the presence of sex-related differences in symptom presentation in patients with aneurysmal subarachnoid hemorrhage (aSAH) to enable earlier diagnosis and treatment. We assessed symptoms on admission to hospital in 343 patients with aSAH in this retrospective single-center cohort-study.
