Subdural empyema : a clinical study
Subdural empyema is a relatively rare condition that carries a high mortality if not treated adequately. The experience at Groote Schuur Hospital over 8 years from 1979 to 1986 was reviewed. 47 cases of subdural empyema following on contiguous or distant infection, or where the source was not …

The pathophysiology of chronic subdural haematoma and the role of the dexamethasone
Chronic subdural haematoma (CSDH) is an encapsulated collection of blood and fluid overlying the surface of the brain, which is often treated with surgical drainage to prevent cerebral compression. Despite treatment it can recur, requiring further surgery and causing significant morbidity. …

The clinical manifestations of chronic subdural hematomas in the Western Metropolitan region
Includes bibliographical references (leaf 43).

The dynamics of shaken baby syndrome
… used to estimate tolerance criteria for causing subdural haematoma by shaking. This research concludes that shaking of a baby could produce bridging vein strain close to the tolerance for failure and hence should be considered a possible cause of subdural haematoma.

Effectiveness of a non-penetrating captive bolt for euthanasia of suckling and weaned piglets
… death in piglets ≤ 9 kg. Skull fractures and subdural and parenchymal hemorrhage were present in all piglets. Neonatal piglets had longer durations of convulsions and heartbeat and more severe damage than weaned piglets, suggesting age and weight effect TBI. Overall, the Zephyr-E was a highly …

Geometric Morphometric and Volumetric Analysis of Contributing Factors to Traumatic Brain Injury
… hemorrhage, intraventricular hemorrhage, and subdural hematoma. Persons over the age of 65 account for 12.9% of the U.S. population and are expected to account for 19% of the population by 2030. As such, TBI related mortality and morbidity within this age range is expected to increase …

Electrocorticographic Neural Correlates of Arm Movements and Associated Goal Orientation in Humans
… target encoding, and goal encoding using subdural electrocorticographic: ECoG) recordings in humans. Using a joystick-based visuomotor task, subjects performed both a standard, delayed match-to-sample center-out task as well as a circular tracing task. Spectral analyses of the ECoG signals …

Linking Molecular, Electrical And Anatomical Properties Of Human Epileptic Brain
… spread of intracranial spikes on long-term subdural electrographical recordings as a means to understand the relationship between spike spread and anatomical structure of the anatomical brain. We found that spikes occur in multiple channels of the subdural electrode grid within a hundred …

Spontaneous empyema and brain abscess in an intensive care population: clinical presentation, microbiology, and factors associated with outcome
… screened patients with spontaneous epidural or subdural empyema and/or brain abscess treated at a tertiary care center between January 2012 and December 2019. Patients with postoperative infections or spinal abscess were excluded. Medical records were reviewed for baseline characteristics, …

Safety of Epidurally Administered Ketorolac in Dogs
… phlebitis in 2 of 8 treatment dogs and minor subdural inflammation in one control dog. No changes to the neural structures were noted in any dogs. Epidural administration of ketorolac did not cause clinical signs, alteration in CSF values, or pathologic changes to the spinal cord when used for …

Relationships of intracranial pressure, cerebrospinal fluid space and head circumference in young children
… Evans ratio was 0.27 ± 0.06. The significant subdural hygroma (SDHG) was detected in 25 patients and the average thickness of it was 3.4 ± 2.7mm. There was a significant positive correlation between the ICP and the HC (r=.474, p=.003). Second aged group (group 2, n=31) was composed of 23 boys …

Continuous Multi-Modal Monitoring of Cerebrovascular Reactivity in Adult Traumatic Brain Injury
… diffuse axonal injury, and presence of subdural hematoma) were associated with impaired cerebral autoregulation as measured by ICP derived indices, implicating diffuse cerebral injury as a driver of impaired reactivity. The data also suggest that EC injury burden may play a role in …

Diagnostic Methods in Traumatic Brain Injury
… 20 patients with intracranial hematomas (chronic subdural hematomas, cSDH) and 20 healthy controls were tested with a MWT device. Results: In studies I and II, differences were observed in the diffusion parameters (fractional anisotropy, FA, and diffusivity, here referred to as trace) of the …

Bioengineering Analysis of Traumatic Brain Injury
… The realistic case study suggested that the subdural haematoma patients, as compared to the epidural haematoma patients, were exposed to more significant secondary swelling, which agrees well with the historical clinical findings. In addition to the realistic TBI case studies, an idealised …

Untersuchung zu Charakteristika und prognostisch bedeutenden Faktoren von Hirnabszessen : eine retrospektive Analyse der Erfahrungen bei 36 Patienten der Klinik für Neurochirurgie der RWTH Aachen 1990-2002
… 8.3% suffered from an abscess accompanied by a subdural empyema. There was no difference between these three groups respecting prognosis. The abscesses were mostly located in the frontal (38.4% of the solitary lesions) and temporal lobe (26.9%), these two locations also being associated with the …

Network Dynamics of Visual Object Recognition
<p>Visual object recognition is the principal mechanism by which humans and many animals interpret their surroundings. Despite the complexity of neural computation required, object recognition is achieved with such rapidity and accuracy that it appears to us almost effortless. Extensive human and …
