Fierz A. Risks and regulation of rubber scattershot in Switzerland: a narrative review. Eye (Lond) 2024:10.1038/s41433-024-03215-w. [PMID: 38977820 DOI: 10.1038/s41433-024-03215-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 06/15/2024] [Accepted: 06/24/2024] [Indexed: 07/10/2024] Open
Abstract
Multiple kinetic impact projectiles (KIPs) are responsible for most eye injuries by crowd-control weapons. This review aims to outline an underreported, ongoing series of eye injuries by rubber scattershot in Switzerland, and to relate current knowledge about thresholds for lasting visual loss to the energy limits set on KIPs in crowd control, by way of a retrospective compilation of cases from publicly available records and a review of the pertinent literature. Scattershot can cause irreversible visual loss. Since 1980, there have been 36 known cases of eye injuries by rubber pellets in Switzerland. In 2023, the incidence was higher here than at the peak of protests in France. KIPs were originally cleared for use in crowd control at kinetic and area-normalised energies assumed to lie below the threshold for ocular penetration. However, closed globe injuries suffice to cause permanent visual loss. Lower energy thresholds for lasting damage have been confirmed by the newer literature on paintballs, airbags, air guns and toys. These values may differ in vivo versus in vitro, and in humans versus in animals. There is no clear consensus on how best to predict loss of vision. Underreporting the risks of crowd-control weapons may contribute to their prolonged and increasingly liberal use. Regulations should consider what is known on energy thresholds for permanent visual loss. It is critical for ophthalmologists to be involved in the evaluation and monitoring of eye injuries caused by projectiles, including KIPs and toys. An interdisciplinary approach could help to elucidate damage thresholds.

[PMID: 36727717 PMCID: PMC10391713 DOI: 10.1227/neu.0000000000002367] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 11/15/2022] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Traumatic brain injury (TBI) is a leading cause of homicide-related death in the United States. Penetrating TBI associated with firearms is a unique injury with an exceptionally high mortality rate that requires specialized neurocritical trauma care. OBJECTIVE To report incidence patterns of firearm-related and nonfirearm-related TBI homicides in the United States between 2000 and 2019 by demographic characteristics to provide foundational data for prevention and treatment strategies. METHODS Data were obtained from multiple cause of death records from the National Vital Statistics System using Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database for the years 2000 to 2019. Number, age-adjusted rates, and percent of firearm and nonfirearm-related TBI homicides by demographic characteristics were calculated. Temporal trends were also evaluated. RESULTS During the study period, there were 77 602 firearm-related TBI homicides. Firearms were involved in the majority (68%) of all TBI homicides. Overall, men, people living in metro areas, and non-Hispanic Black persons had higher rates of firearm-related TBI homicides. The rate of nonfirearm-related TBI homicides declined by 40%, whereas the rate of firearm-related TBI homicides only declined by 3% during the study period. There was a notable increase in the rate of firearm-related TBI homicides from 2012/2013 through 2019 for women (20%) and nonmetro residents (39%). CONCLUSION Firearm-related violence is an important public health problem and is associated with the majority of TBI homicide deaths in the United States. The findings from this study may be used to inform prevention and guide further research to improve treatment strategies directed at reducing TBI homicides involving firearms.

Increased aneurysm wall permeability colocalized with low wall shear stress in unruptured saccular intracranial aneurysm. J Neurol 2021; 269:2715-2719. [PMID: 34731309 DOI: 10.1007/s00415-021-10869-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 10/19/2021] [Accepted: 10/20/2021] [Indexed: 12/01/2022]
Abstract
Aneurysm wall permeability has recently emerged as an in vivo marker of aneurysm wall remodeling. We sought to study the spatial relationship between hemodynamic forces derived from 4D-flow MRI and aneurysm wall permeability by DCE-MRI in a region-based analysis of unruptured saccular intracranial aneurysms (IAs). We performed 4D-flow MRI and DCE-MRI on patients with unruptured IAs of ≥ 5 mm to measure hemodynamic parameters, including wall shear stress (WSS), oscillatory shear index (OSI), WSS temporal (WSSGt) and spatial (WSSGs) gradient, and aneurysm wall permeability (Ktrans) in different sectors of aneurysm wall defined by evenly distributed radial lines emitted from the aneurysm center. The spatial association between Ktrans and hemodynamic parameters measured at the sector level was evaluated. Thirty-one patients were scanned. Ktrans not only varied between aneurysms but also demonstrated spatial heterogeneity within an aneurysm. Among all 159 sectors, higher Ktrans was associated with lower WSS, which was seen in both Spearman's correlation analysis (rho = - 0.18, p = 0.025) and linear regression analysis using generalized estimating equation to account for correlations between multiple sectors of the same aneurysm (regression coefficient = - 0.33, p = 0.006). Aneurysm wall permeability by DCE-MRI was shown to be spatially heterogenous in unruptured saccular IAs and associated with local WSS by 4D-flow MRI.
