BACKGROUND: Falls from height are among the most common trauma cases presenting to emergency departments and often cause mortality and morbidity. In the present study, we aimed to determine the factors that effectively reduce mortality caused by falls from height.

This study investigated correlations between mortality, stroke subtype and stroke severity with serum osteoprotegerin (OPG) and S-100 protein levels prior to the treatment of patients admitted to the emergency department and diagnosed with ischaemic stroke. Pretreatment serum samples were collected from patients (n = 90) to determine OPG and S-100 protein levels. Age- and sex-matched healthy individuals (n = 16) served as controls. Compared with controls, OPG and S-100 protein levels were significantly higher in the cardioembolic and atherothrombotic stroke groups. Within the stroke group, OPG levels were significantly higher in the cardioembolic and atherothrombotic stroke groups compared with the transient ischaemic attack (TIA) group. S-100 protein levels were significantly higher in the atherothrombotic stroke group than in the lacunar stroke and TIA groups, and in the cardioembolic stroke group compared with the lacunar stroke group. Serum OPG and S-100 protein levels were significantly higher in patients who died compared with survivors. In predicting stroke subtype and severity, although both OPG and S-100 protein levels were indicators, S-100 protein was more valuable for mortality prediction.

This study evaluated serum neuron-specific enolase (NSE), cytokine and high-sensitivity C-reactive-protein (hs-CRP) levels, along with the Glasgow Coma Scale (GCS) and Revised Trauma Score (RTS), as predictors of mortality in the early posttraumatic period, in 100 Turkish patients with blunt head trauma. Overall patient mortality was 27%. There was a significant association between age and mortality, and mortality was negatively correlated with GCS and RTS. Head injury severity (GCS) was significantly related to NSE, hs-CRP, interleukin (IL)-6, IL-8 and tumour necrosis factor (TNF)-alpha levels. Mortality correlated positively with IL-6, IL-8, TNF-alpha and hs-CRP levels. NSE, hs-CRP, IL-6, IL-8 and TNF-alpha levels were significantly higher in non-survivors compared with survivors. GCS score < or =8, younger age and NSE levels were significant independent predictors of mortality. During the early post-traumatic period, NSE may be an objective alternative criterion to the GCS, in the management of patients with blunt head trauma.
