Traumatic brain injury (TBI) is major contributor to the global burden of disease, especially in low- and middle- income countries, where most TBIs are traffic-related. Evidence shows that helmets protect against severe TBI. Cambodia continues to have the greatest motorcycle fatality rate in Southeast Asia. We investigated whether the National Motorcycle Helmet Law introduced in January 2016 had an impact on the epidemiology of motorcycle-related TBI in a neurosurgical referral center in Phnom Penh. This is a cross-sectional study of all patients admitted to the Department of Neurosurgery at Preah Kossamak Hospital with TBI following motorcycle accidents between January 2014 and December 2017. TBI admissions increased (from 234 in 2014 to 768 in 2017). The median age was 26 years, and most patients were male. The percentage of helmeted patients was 9% in 2014 and 13% in 2015; this increased to 18% in 2016, but dropped to 9% in 2017. Most TBIs occurred during the evening rush hour. Since 2016, more patients wore helmets in the daytime (up to 23%) than at night (5% between 1:00 and 5:00 am). Skull fracture, the most common pathology pre-law, decreased by 25% post-law (P < 0.001). With growing urbanization and motorization, TBI is a significant cause of morbidity and mortality in Cambodia. Two years after helmets became compulsory, most patients with TBI are still unhelmeted. Likely contributing factors are low penalty for noncompliance and inconsistent law enforcement. TBI is a major public health problem warranting further efforts to understand how to improve prevention strategies and advocate for change. [ABSTRACT FROM AUTHOR]

Background Spine pathology is a common reason for admission to neurosurgical units in low- and middle-income countries (LMICs) and can have high morbidity rates from lack of specialized institutes. However, good surgical outcomes and quality-of-life scores have been reported in LMICs. This study details the complication rates and predictive factors from spine surgery at a large hospital in Cambodia, aiming to identify high-risk patients to improve surgeon understanding of these complications for improved pre-operative planning and patient counseling. Methods This is a retrospective review of patients admitted for spine conditions to Preah Kossamak Hospital in Phnom Penh, Cambodia (2013-2017). Univariate analysis was conducted on potential predictive factors; variables with P < 0.1 were entered into multivariate logistic regression models. Results Seven hundred seventy-three patients were included. Forty-six patients had complications including wrong level surgery, hardware failure, and infection. On multivariate analysis, patients from the provinces of Kratie (P = 0.009) or Sihanoukville (P = 0.036), and those that delayed seeking care for more than 1 year after injury (P = 0.027), were significant predictive factors of postoperative complications, and American Spinal Injury Association grade A injury (P = 0.020) was a predictive factor of poor outcome. Conclusions Many factors play a role in spine surgery complications in LMICs, including limited access to intra-operative technology, low follow-up rates, and minimal physiotherapy and rehabilitation capabilities. Patients with long delays in presentation, American Spinal Injury Association grade A injuries, and lumbar-level surgery may be especially susceptible to complications and postoperative morbidity. Despite this, institutions have reported encouraging spine trauma outcomes, and spine surgeries are becoming more accepted and safe operations in many LMICs. [ABSTRACT FROM AUTHOR]
