Purpose: To identify risk factors for the development of culture-positive endophthalmitis after repair of open globe injuries.
Methods: We retrospectively reviewed the medical records of 629 consecutive patients with open globe injuries admitted to King Abdulaziz University Hospital between May 1996 and January 2008.
Results: Endophthalmitis developed in 12 (1.9%) patients. The following factors were significantly associated with endophthalmitis by univariate analysis: delayed presentation (>24 hours) (p=0.008), rural address (p=0.013), and dirty wound (p=0.012). Logistic regression analysis identified dirty wound to be associated with the development of endophthalmitis (odds ratio = 11.6; 95% confidence interval [CI] = 2.67-50.6). On logistic regression analysis, presence of retained intraocular foreign body (IOFB) in association with rural address (odds ratio = 11.0; 95% CI = 1.44-83.3) or dirty wound (odds ratio = 9.2; 95% CI = 1.22-69.1) was associated with development of endophthalmitis. Endophthalmitis was a significant negative predictor for final good visual outcome (p=0.00261) and was significantly associated with hypotony (p=0.033).
Conclusions: Delayed presentation, rural address, and dirty wound were associated with development of endophthalmitis. Retained IOFB in association with rural address or dirty wound was associated with a particularly high risk of endophthalmitis.

Introduction: Abdominal wall reconstruction (AWR) with ventral hernia repair (VHR) in the setting of contamination poses unique and controversial challenges. The purpose of this study was to examine the efficacy of onlay resorbable biosynthetic mesh against underlay biologic mesh in contaminated VHR with AWR.
Methods: A single-center retrospective review from 2015 to 2021 was performed examining subjects who underwent VHR with AWR in contaminated fields (Centers for Disease Control wound class II-IV).

The more science progresses, the more life and society change. Medicine also changes with the times and the culture. This is also true for radiation emergency medicine, which includes dose-assessment leading to diagnosis, treatment, medical follow-up and prognosis of persons who have developed acute injury or illness due to radioactive contamination or radiation exposure.

Importance: Originally developed for use in contaminated fields, there is growing evidence against the use of biologic and biosynthetic mesh in ventral hernia repair. However, its prevalence and patterns of use in current practice are largely unknown.
Objectives: To describe the prevalence of biologic and biosynthetic mesh use in ventral hernia repair and to identify factors associated with its use.

Purpose: This study focuses on analytical computer simulations performed to investigate a hypothetical event where the activation of a radiological dispersion device (RDD) triggers a crisis.
Materials And Methods: The methodology presents steps centered on the initial evaluation phase of the event (initial 100 hours), aiming to evaluate the radiological risks regarding the development of leukemia. Local environmental changes, sex, and age were also used to assess risks.
