Civilian craniocerebral gunshot injuries (CGIs) are rare but increasing in incidence in the developing world and there is scare literature on presentation, injury characteristics, prognostic indicators, and complications of brain trauma due to projectiles. ⋯ Admission GCS and number of lobes involved are highly prognostic of outcome. Patients with a GCS score ≥9 and unilobar injury on computed tomographic scans may benefit the most from surgical management.

Reliability of ocular ultrasonography findings for pre-surgical evaluation in various vitreo-retinal disorders.
To find the reliability of ocular ultrasonography (USG) for pre-surgical evaluation in various vitreo-retinal conditions. ⋯ Our study highlighted that the reliability of USG findings was least in cases of trauma, hence requiring special care while reporting.

Cumulative Effective Dose Associated With Computed Tomography Examinations in Adolescent Trauma Patients.
The aims of this study were to analyze cumulative effective dose (cED) and to assess lifetime attributable risk (LAR) of cancer due to radiation exposure during computed tomography (CT) examinations in adolescent trauma patients. ⋯ The overall radiation-induced cancer risk due to CT examinations performed for the initial assessment of minor trauma was found to be relatively low in adolescent patients. However, adolescent patients with major trauma were exposed to a substantial amount of radiation during multiple CT examinations.

Delayed Increases in Microvascular Pathology Following Experimental Traumatic Brain Injury Are Associated with Prolonged Inflammation, Blood Brain Barrier Disruption and Progressive White Matter Damage.
Traumatic brain injury (TBI) is a significant risk factor for chronic traumatic encephalopathy (CTE), Alzheimer's disease (AD), and Parkinson's disease (PD). Cerebral microbleeds, focal inflammation, and white matter damage are associated with many neurological and neurodegenerative disorders including CTE, AD, PD, vascular dementia, stroke, and TBI. This study evaluates microvascular abnormalities observed at acute and chronic stages following TBI in rats, and examines pathological processes associated with these abnormalities. ⋯ Microbleeds were surrounded by glial scars and co-localized with CD68 and IgG puncta stainings, suggesting that localized BBB breakdown and inflammation were associated with vascular damage. Our results indicate that evolving white matter degeneration following experimental TBI is associated with significantly delayed microvascular damage and focal microbleeds that are temporally and regionally associated with development of punctate BBB breakdown and progressive inflammatory responses. Increased understanding of mechanisms underlying delayed microvascular damage following TBI could provide novel insights into chronic pathological responses to TBI and potential common mechanisms underlying TBI and neurodegenerative diseases.

Long-lasting significant functional improvement in chronic severe spinal cord injury following scar resection and polyethylene glycol implantation.
We identified a suitable biomatrix that improved axon regeneration and functional outcome after partial (moderate) and complete (severe) chronic spinal cord injury (SCI) in rat. Five weeks after dorsal thoracic hemisection injury the lesion scar was resected via aspiration and the resulting cavity was filled with different biopolymers such as Matrigel™, alginate-hydrogel and polyethylene glycol 600 (PEG) all of which have not previously been used as sole graft-materials in chronic SCI. Immunohistological staining revealed marked differences between these compounds regarding axon regeneration, invasion/elongation of astrocytes, fibroblasts, endothelial and Schwann cells, revascularization, and collagen deposition. ⋯ The beneficial effects of PEG-implantation into the resection-cavity were accompanied by long-lasting significant locomotor improvement over a period of 8months. Following complete spinal re-transection at the rostral border of the PEG-graft the locomotor recovery was aborted, suggesting a functional role of regenerated axons in the initial locomotor improvement. In conclusion, scar resection and subsequent implantation of PEG into the generated cavity leads to tissue recovery, axon regeneration, myelination and functional improvement that have not been achieved before in severe chronic SCI.
