cervical injury, blunt and penetrating trauma, hardly lead to morbidity and mortality in children population but it is clinically important. although blunt trauma is less prevalence in children than penetrating trauma, it is life threatening due to laryngotracheal rupture. bicycle accidents are common reason of blunt trauma. blunt laryngotracheal injury is rare in children because mandibular bo...

introduction: blunt neck and laryngeal trauma is rare. since such injuries can be life threatening, their early management remarkably affects the immediate probability of patients’ survival and their long-term quality of life. materials and methods: in this retrospective and descriptive study, medical records of 54 patients with blunt neck and laryngeal trauma, who were referred to imam khomein...

this paper is a computational study of the behavior of aerodynamics  characteristics of an airfoil with blunt trailing edge and  studies the effects aerodynamic performance caused by modifications made to the trailing edge. blunt trailing edge airfoils are of interest in the engineering of large wind turbine blades because they allow for a strong structure with a high aerodynamic lift to struct...

Cardiac laceration from blunt thoracic trauma is not a common presentation. The rate of mortality due to this injury is very high since it is not diagnosed and treated immediately. In this study, we present the case of a 65-year-old man with blunt cardiac trauma, causing right atrial rupture and pericardial tamponade. Successful management of this patient was firstly done with initial pericardi...

conclusions the loss of hrc at the onset of admission may predict mortality in patients with blunt trauma. lower entropy, in recently admitted patients with intra-abdominal bleeding, may indicate laparotomy when the vital signs are stable. background nonlinear analysis of heart rate variability (hrv) has been recently used as a predictor of prognosis in trauma patients. objectives we applied no...

BACKGROUND Blunt cardiac injury is a rare trauma entity. Here, we sought to evaluate the relevance and prognostic significance of blunt cardiac injury in severely injured patients. METHODS In a retrospective multicentre study, using data collected from 47,580 patients enrolled to TraumaRegister DGU (1993-2009), characteristics of trauma, prehospital / hospital trauma management, and outcome a...

BACKGROUND Focused assessment with sonography in trauma (FAST) is widely used and endorsed by guidelines, but little evidence exists regarding the utility of the cardiac portion in blunt trauma. The traditional FAST includes the routine performance of cardiac sonography, regardless of risk for hemopericardium. STUDY OBJECTIVES Our goal was to estimate the prevalence of hemopericardium due to ...

BACKGROUND Blunts are hollowed-out cigars or leaf tobacco filled with marijuana. Use of blunts has increased since the 1990s and, in 2005, 3.5% of all American youth were estimated to have used blunts in the past month. Blunt smokers may have greater odds of cannabis and tobacco dependency and are at risk of smoking-related diseases. Previous studies have suggested that blunt use is more common...
