IntroductionThe incidence and epidemiological causes of maxillofacial (MF) trauma varies widely. The objective of this study is to point out maxillofacial trauma patients’ epidemiological properties and trauma patterns with simultaneous injuries in different areas of the body that may help emergency physicians to deliver more accurate diagnosis and decisions.MethodsIn this study we analyze etiology and pattern of MF trauma and coexisting injuries if any, in patients whose maxillofacial CT scans was obtained in a three year period, retrospectively.Results754 patients included in the study consisting of 73.7% male and 26.3% female, and the male-to-female ratio was 2.8:1. Mean age was 40.3 ± 17.2 years with a range of 18 to 97. 57.4% of the patients were between the ages of 18–39 years and predominantly male. Above 60 years of age, referrals were mostly woman. The most common cause of injuries were violence, accounting for 39.7% of the sample, followed by falls 27.9% and road traffic accidents 27.2%. The primary cause of injuries were violence between ages 20 and 49 and falls after 50. Bone fractures found in 56,0% of individuals. Of the total of 701 fractured bones in 422 patients the most frequent was maxillary bone 28,0% followed by nasal bone 25,3%, zygoma 20,2%, mandible 8,4%, frontal bone 8,1% and nasoethmoidoorbital bone 3,1%. Fractures to maxillary bone were uppermost in each age group.8, 9% of the patients had brain injury and only frontal fractures is significantly associated to TBI (p < 0.05) if coexisting facial bone fracture occurred. Male gender has statistically stronger association for suffering TBI than female (p < 0, 05). Most common cause of TBI in MF trauma patients was violence (47, 8%).158 of the 754 patients had consumed alcohol before trauma. No statistically significant data were revealed between alcohol consumption gender and presence of fracture. Violence is statistically significant (p < 0.05) in these patients.ConclusionStudies subjected maxillofacial traumas yield various etiologic factors, demographic properties and fracture patterns probably due to social, cultural and governmental differences. Young males subjected to maxillofacial trauma more commonly as a result of interpersonal violence.
Trauma management shows significant progress in last decades. Determining the time and place of deaths indicate where to focus to improve our knowledge about trauma. We conducted this retrospective study from data of trauma victims who were brought to a major tertiary hospital which is a level one trauma center in Ankara, Turkey, and died even if during transport or in the hospital between 1 March 2010 and 1 March 2013. The patients' demographic characteristics, trauma mechanisms, time frames and causes of deaths determined by physicians were recorded. Traumas were grouped as "high energy trauma" (HET) and "low energy trauma" (LET). Falls from ground level were defined as LET. 209 traumatic deaths due to trauma or trauma-related conditions were found in the study period. 161 of 209 (78 %) patients suffered from HET. Motor vehicle collisions (MVC) (56 %) were the most common mechanism of trauma followed by burns (16 %), falls (11 %), gunshots (9 %) and stabs (6 %) in this group and traumatic brain injuries (TBI) (41 %) were the most common cause of death followed by circulatory collapse (22 %) and multi-organ failure (20 %). 36 % of deaths occurred before arrival at hospital, 25 % in the first 24 h of admission, 18 % between 2nd and 7th day and 21 % after first week. Trimodal distribution of traumatic deaths was not valid for all types of injuries and the most important factor to decrease traumatic deaths is still prevention. Also we have to keep on searching to improve our knowledge about trauma management.
BackgroundIschemia/reperfusion (I/R) injury is harmful to the cardiovascular system and is responsible for the inflammatory response and multiple organ dysfunctions. In this study we investigated the effect of activated clotting time level on the aortic cross-clamping triggers a systemic inflammatory response and it effects to lungs and heart.MethodsEnd organ concentrations of interleukin-6 (IL-6), myeloperoxidase (MPO) and heat shock protein 70 (HSP-70) were determined in four groups of Spraque Dawley rats: ischemic control (operation with cross clamping received IP of 0.9% saline at 2 ml/kg n=7) Sham (operation without cross clamping, n=7), heparin (ACT level about 200), High dose heparin (ACT level up to 600) The infrarenal aorta was clamped for 45 minutes by a mini cross clamp approximately 1cm below the renal artery and 1cm iliac bifurcation in all groups without sham group. Heparin was given intraperitoneal (IP) before the procedure. All rats were sacrificed 48 h later. In a second experiment, the effects of I/R on remote organs (lungs and heart) were harvested for analysis. We evaluated tissue levels of myeloperoxidase, interleukin-6, and heat shock protein (HSP-70) were analyzed as markers oxidative stress and inflammation. Histological analyses of the organs were performed.ResultsThe lungs paranchymal MPO and HSP-70 levels significantly decreased (p<0.05), but IL-6 level was not significant (p>0.05) in heparinized and high dose heparinized groups when compared to ischemic control group. Histopathological evaluation as edema, cell degeneration, inflammation statistically significantly decreased in both group heparinized and high dose heparinized compared with ischemic control group (p<0.05). The heart paranchymal MPO levels significantly decreased in heparinized and high dose heparinized groups when compared to ischemic control group (p=0.023). IL-6, HSP-70 levels were not significant heparinized and high dose heparinized groups when compared to ischemic control group (p=0.0489, p=0.0143). Histopathological evaluation as degeneration statistically significantly decreased in both group heparinized and High dose heparinized compared with ischemic control group (p=0.005).ConclusionHeparin decreased remote organs injury on the lung and heart after ischemia/reperfusion of infra-renal section of the body in the rat model. So, we should be balance to act level for avoid to I/R injury per operative and early post operative period as providing ACT level nearly 200.
Emergency physicians should be better able to recognise the clinical features of anaphylaxis, so as to treat the episode promptly and appropriately. Delay in diagnoses could lead to incomplete treatment and even be fatal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
