Abstract Background Major trauma is a leading cause of morbidity and mortality worldwide with hemorrhage accounting for 40% of deaths. Acute traumatic coagulopathy exacerbates bleeding, but controversy remains over the degree to which inhibition of procoagulant pathways (anticoagulation), fibrinogen loss, and fibrinolysis drive the pathologic process. Through a combination of experimental study in a murine model of trauma hemorrhage and human observation, the authors’ objective was to determine the predominant pathophysiology of acute traumatic coagulopathy. Methods First, a prospective cohort study of 300 trauma patients admitted to a single level 1 trauma center with blood samples collected on arrival was performed. Second, a murine model of acute traumatic coagulopathy with suppressed protein C activation via genetic mutation of thrombomodulin was used. In both studies, analysis for coagulation screen, activated protein C levels, and rotational thromboelastometry (ROTEM) was performed. Results In patients with acute traumatic coagulopathy, the authors have demonstrated elevated activated protein C levels with profound fibrinolytic activity and early depletion of fibrinogen. Procoagulant pathways were only minimally inhibited with preservation of capacity to generate thrombin. Compared to factors V and VIII, proteases that do not undergo activated protein C–mediated cleavage were reduced but maintained within normal levels. In transgenic mice with reduced capacity to activate protein C, both fibrinolysis and fibrinogen depletion were significantly attenuated. Other recognized drivers of coagulopathy were associated with less significant perturbations of coagulation. Conclusions Activated protein C–associated fibrinolysis and fibrinogenolysis, rather than inhibition of procoagulant pathways, predominate in acute traumatic coagulopathy. In combination, these findings suggest a central role for the protein C pathway in acute traumatic coagulopathy and provide new translational opportunities for management of major trauma hemorrhage.

Background. Hand injuries are common worldwide and lead to heavy financial losses in terms of treatment, job loss, and time off duty. There is paucity of data on hand injuries in sub-Saharan Africa. The aim of this study was to determine the burden and early outcomes of hand injuries at a tertiary hospital.Method. A descriptive prospective study. Eligible patients were recruited over 5 months and followed up for four weeks. Pain, nerve function, and gross functions of the hand were assessed.Results. In total 138 patients were enrolled out of 2940 trauma patients. Of these, 122 patients returned for follow-up. The majority of the patients were males (83%). Mean age was 26.7 years (SD 12.8). The commonest places of injury occurrence were the workplace (36%), home (28%), and on the road (traffic crushes) (23%). Machines (21.3%) were the commonest agent of injuries; others were knives (10%) and broken glass (10%). Sixty-three (51%) patients still had pain at one month.Conclusions. Hand injuries accounted for 4.7% of all trauma patients. Road traffic crushes and machines were the commonest causes of hand injuries. Men in their 20s were mostly involved. Sensitization for prevention strategies at the workplace may be helpful.

Background: Coagulopathy following major trauma is conventionally attributed to activation of coagulation factors. We hypothesized that early coagulopathy is due to tissue hypoperfusion and investigated thrombomodulin (TM) as early marker of endothelial injury in poly trauma patient.Methods: This was a prospective cohort study of major trauma patients admitted to a single trauma center. Blood was drawn within 10 minutes of arrival for analysis of TM. We assess its association with blood transfusion, length of hospital stays and mortality.Results: A total of 90 patients were enrolled. An increasing lactate was associated with high soluble TM. High TM was significantly associated with increased mortality, blood transfusion requirements, hospital stay.Conclusions: Acute traumatic coagulopathy (ATC) occurs only in the presence of tissue hypoperfusion which we have measured in form of lactate and coagulopathy measured using international normalized ratio (INR) as standard. Admission serum TM can be predictive of clinical outcomes following major trauma.

Purpose Early identification of trauma patients at risk of developing acute traumatic coagulopathy is important in initiating appropriate, coagulopathy-focused treatment. A clinical acute traumatic coagulopathy prediction tool is a quick, simple method to evaluate risk. The COAST score was developed in Australia and we hypothesised that it could predict coagulopathy and bleeding-related adverse outcomes in other advanced trauma systems. We validated COAST on a single-centre cohort of trauma patients from a trauma centre in Belgium. Methods The COAST score was modified to suit available data; we used entrapment, blood pressure, temperature, major chest injury and abdominal injury to calculate the score. Acute traumatic coagulopathy was defined as international normalised ratio >1.5 or activated partial thromboplastin time >60 s upon arrival of the patient to the hospital. Data were extracted from the local trauma registry on patients that presented between 1 January and 31 December 2015. Results In all, 133 patients met the inclusion criteria (>16 years old, available COAST and outcome data) for analysis. The COAST score had an area under the receiver operating characteristics curve of 0.941 (95% CI: 0.884–0.999) and at COAST ≥3, it had 80% sensitivity and 96% specificity. The score also identified patients with higher rates of mortality, blood transfusion and emergent surgery. Conclusion This retrospective cohort study demonstrated the utility of the COAST score in identifying trauma patients who are likely to have bleeding-related poor outcomes. The early identification of these patients will facilitate timely, appropriate treatment for acute traumatic coagulopathy and minimise the risk of over-treatment. It can also be used to select patients with acute traumatic coagulopathy for trials involving therapeutic agents targeted at acute traumatic coagulopathy.

Abstract Background: Acute traumatic coagulopathy occurs in both pediatric and adult trauma patients and is associated with an increased risk of mortality. Trauma patients not only have increased risk for hemorrhagic complications, but also are at increased risk for thrombosis due to multiple factors including local tissue injury, inflammation, and immobility. The complex underlying pathophysiology of coagulation abnormalities associated with traumatic injury have yet to be fully elucidated. Additionally, there are significant differences in the hemostatic system of pediatric patients compared to adults. Objectives: The purpose of this study was to determine the levels of coagulation parameters including von Willebrand factor (VWF) antigen and ADAMTS13 activity in pediatric trauma patients and evaluate for possible association with injury severity and/or mortality. Methods: This study utilized plasma specimens collected from pediatric trauma patients that presented to our institution over a 2-year time period. The specimens were collected at initial presentation and 24 hours later. The injury severity was estimated using both the Glasgow Coma Scale (GCS) and Injury Severity Score (ISS). A cohort of control samples was obtained from pediatric patients for elective surgical procedures over the same time period. Plasma VWF antigen was determined by a sandwich ELISA; plasma ADAMTS13 activity was determined by FRETS-VWF73. The results were determined by nonparametric tests for the differences in median values. Results: A total of 106 trauma patient samples at initial time point, 78 trauma samples at 24 hour time point, and 54 control samples were obtained and utilized for study. There were statistically significant differences (p<0.05) in the plasma levels of VWF antigen, ADAMTS13 activity, and the ratio of ADAMTS13 activity to VWF antigen for the trauma patient samples at initial presentation when compared to controls (Table 1). At 24 hours, there were still statistically significant differences between ADAMTS13 activity and the ratio of ADAMTS13 activity to VWF antigen in trauma patients compared to controls, but there was no significant difference in VWF antigen between the two cohorts (Table 2). There was a significant difference between the decrease in ADAMTS13 activity and injury severity as estimated by ISS ³ 15 or GCS < 8 at both time points; however, ADAMTS13 activity was not statistically different in survivors vs. non-survivors. A higher VWF antigen level at initial presentation was the only factor found to be significantly different in non-survivors. Conclusions: This study demonstrates significant differences in plasma ADAMTS13 activity and VWF antigen in pediatric trauma patients compared to controls. In patients with more severe injuries as estimated by GCS and ISS, there was also a significant association with decreased levels of ADAMTS13 activity. These finding may underlie part of the prothrombotic propensity in microcirculation that occurs in patients post-trauma. Further investigation is warranted to better understand the mechanisms of acute traumatic coagulopathy and potential prognostic factors, and to determine the most effective interventions for acute traumatic coagulopathy in the pediatric population.

Cyclical Mastalgia

Introduction. Mastalgia is a common breast condition among women referred to breast clinics worldwide. Whereas the prevalence is known in the Western world and Asia, the prevalence of the disease is unknown in many African countries. The aim of this study therefore was to determine the prevalence and describe factors associated with mastalgia among women attending a tertiary hospital in sub-Saharan Africa. Methods. A cross-sectional study was done in Kampala, Uganda. Mastalgia was defined as self-reported breast pain (unilateral or bilateral) for a period not less than two months. A pretested questionnaire was used to collect the data and statistical analysis was performed using SPSS version 11. Ethical approval was obtained. Results. Out of the 1048 women who presented to the breast clinic during the study period, 168 (16%) were diagnosed with mastalgia in the absence of breast cancer. Noncyclical and cyclical mastalgia were 22/168 (13%) and 5/168 (3%), respectively. The onset of noncyclical category as compared to the cyclical type of mastalgia was observed to manifest before 24 years of age (P=0.006). Conclusion. Mastalgia was a common condition among women in this sub-Saharan African setting as is elsewhere. The early onset mastalgia in this sub-Saharan African study requires further exploration for determination of its risk factors.
