Introduction: Combat ground maneuvers consist of various platforms and have several environmental characteristics, influenced by the terrain, the operational mission, and the force's capabilities. This study assesses data on injuries sustained during urban warfare, aiming to evaluate the relationship between injury characteristics, maneuver platform, and personal protective gear on the battlefield.Materials and Methods: IDF soldiers injured infantry soldiers from the "Cast Lead" and the "Protective Edge" operations in the Gaza Strip (2008-2009 and 2014, respectively) were divided into four groups according to the maneuver platform and the environment: mounted infantry (armored and unarmored vehicle) and dismounted infantry (urban and open area). The primary outcome was the severity of the injury, and the secondary outcome was the injured body part.Results: Overall, 588 casualties were included in the final analysis, of whom 507 were dismounted infantry soldiers (265 in open terrain and 242 in urban area) and 81 were mounted infantry soldiers (20 in unarmored and 61 were injured in armored vehicles). The Injury Severity Score was similar in all subgroups. Open terrain subgroups were found to have fewer head injuries and higher levels of lower extremity injuries, similar to the unarmored vehicle group. More facial injuries were documented in the urban area group.Conclusions: The Injury Severity Score was not influenced by environmental protection. Although we found differences in the injured body parts, further studies on the exact mechanism of injury are needed to elucidate further the relationship and differences between the various platforms used and injuries seen in urban warfare, aiming for tailor-made protection.

To evaluate the correlation between keratoconus and systemic manifestations of tissue hyperlaxity in the general population. In this population based cross-sectional study 940,763 medical records of Israeli adolescents and young adults in military service were reviewed. Demographic and medical data were extracted. The prevalence of ligament injuries, habitual orthopedic deformities and umbilical/inguinal hernia was evaluated in cases with and without keratoconus. The association was tested using uni- and multivariant analyses. Overall 938,411 adolescents and adults were included. Mean age was 17.55 ± 1.50 years, and 40.70% were female. Keratoconus was documented in 1,529 cases, with a prevalence of 0.16%. Compared to the general population, patients with keratoconus were significantly more likely to be diagnosed with genu varum/valgus (OR = 2.75, CI 1.48–5.13, p = 0.0015), pes planus (OR = 1.97, 95% CI: 1.62–2.38, p < 0.0001), scoliosis (OR = 1.88, 95% CI: 1.45–2.43, p < 0.0001) and umbilical/inguinal hernias (OR = 2.18, 95% CI: 1.47–3.24, p = 0.0001). On multivariate analysis the results remained significant (p < 0.05 for all). Joint injuries (ankle sprains, shoulder dislocation and injury to knee ligaments and menisci) were not significantly related to keratoconus (p > 0.05 for all). In this large cohort of adolescents and young adults, an association was found between keratoconus and connective tissue hyperlaxity manifestations involving the knees, feet, spine and abdomen. These findings suggest that keratoconus might be a manifestation of a generalized connective tissue disorder, rather than just a local ocular phenomenon. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the safety of a new injector, the Raysert R-INJ-04/18, for implantation of the C-flex intraocular lens (IOL). Setting: Ophthalmology Department, Kaplan Medical Center, Rehovot, Israel. Design: Experimental study. Methods: Sixty IOLs were subdivided into 2 equally sized groups. Group A IOLs were injected using the established R-INJ-04 injector, and those in Group B were injected with the new injector. The IOLs were injected into a Petri dish. Subsequently, all IOLs and injectors were evaluated macroscopically and microscopically and then photographed under light microscopy (LM). Two IOLs in each group were randomly chosen and sent for evaluation by scanning electron microscopy (SEM) and energy dispersive analysis of x-ray. All remaining IOLs were sent for power and modulation transfer function (MTF) analysis. Results: All Group B IOLs were successfully injected without evident signs of scratching, cracks, or deposits on LM and SEM examination. In Group A, findings were confined to a singular incidence of a small deposit detected on the periphery of the posterior optical surface of the IOL, with corresponding findings detected on the injector nozzle. No signs of scratching, cracks, or deposits were found in the rest of the IOLs or injectors. The power and MTF analyses were within the normal range for all IOLs. Conclusion: The new 1.8 mm external diameter soft-tipped injector for 2.4 to 2.2 mm incisions was shown to be safe for the implantation of the C-flex 21.0 diopter IOL.

Background: This article summarizes the experience with Role 1 care for 135 Syrian children who received medical care during the year 2013 as part of an ongoing humanitarian effort.Methods: The database included demographic information, point-of-injury assessment and outcome, and was analyzed using SPSS.Results: Trauma casualties were the majority of the group (84 cases), and mostly male. Almost one-third of casualties arrived more than 6 hours after injury, and time of injury was unknown in another third. The most common mechanism of injury was shrapnel (51.2%), followed by gunshot wounds (22.6%). Gunshot wound victims were significantly older than shrapnel and artillery victims (p < 0.01, < 0.05, respectively). Only 14 cases (14.28%) underwent previous interventions in Syria. Most of the casualties (44 cases, 52.4%) underwent at least one procedure during Role 1 treatment with a high overall success rate (93.18%) that was not correlated to Advanced Life Support provider type (physician [MD], emergency medical technician-paramedic, or both). Mortality was low (3 cases).Conclusion: The study cohort exhibits several unique features, including a delay in arrival to medical care, paucity of prior care and information, and the specific mechanisms of injury. Our study suggests that Advanced Life Support providers do not differ significantly in Role 1 treatment choices and procedure success. [ABSTRACT FROM AUTHOR]
