The use of ultrasound in the evaluation of blunt thoraco-abdominal trauma is well described. Evidence for the use of ultrasound in the evaluation of penetrating cardio-thoracic and abdominal trauma, however, is more limited and varied. Current literature demonstrates that ultrasound is an excellent screening tool for penetrating thoracic and cardiac injuries with a high sensitivity for detectin...

The boundary of the region in spacetime containing future-trapped closed surfaces is considered. In asymptotically flat spacetimes, this boundary does not need to be the event horizon nor a dynamical/trapping horizon. Some properties of this boundary and its localization are analyzed, and illustrated with examples. In particular, fully explicit future-trapped compact surfaces penetrating into f...

Penetrating landmine injuries are the unavoidable consequences of military conflicts. They are potentially life-threatening. The mortality rates in the literature range from 23% to 92% and are considerably higher in patients admitted with poor neurologic state. Penetrating craniocerebral injuries require early surgical management designated to prevent infection and remove foreign objects, necro...

Penetrating neck injuries by traditional weapons are rare entity in the modern era of sophisticated weapons. We report an unusual case of penetrating neck injury by a metallic arrow entering anterior neck in zone II and its tip coming out of neck posteriorly causing difficulty for patient to lie down as well as posing challenge to intubate. Arrows are low velocity projectile and from a close pr...

BACKGROUND Little is known about the distribution of gap junctions and ion channels in the atrioventricular node, even though the physiology and pathology of the atrioventricular node is ultimately dependent on them. METHODS AND RESULTS The abundance of 30 transcripts for markers, gap junctions, ion channels, and Ca(2+)-handling proteins in different regions of the rabbit atrioventricular nod...

purpose: to report a case of pseudoexfoliation syndrome in young keratoconus patient following penetrating keratoplasty. case report: a 37 year old man who underwent penetrating keratoplasty 13 years ago in his left eye due to keratoconus developed pseudoexfoliation (pex) syndrome in the operated eye. apart from pex material deposition on the crystalline lens ophthalmic exam was within normal l...

background penetrating and impalement injuries of the hand and fingers are one of the commonest presentations at the hospital’s emergency rooms. this study assessed the characteristics of patients who suffered foreign body injuries to the hands and documented the pattern of diagnosis and management at a specialist plastic surgical facility. methods the study was conducted at the department of p...

BACKGROUND The American College of Surgeons' Committee on Trauma's recent prehospital trauma life support recommendations against prehospital spine immobilization (PHSI) after penetrating trauma are based on a low incidence of unstable spine injuries after penetrating injuries. However, given the chronic and costly nature of devastating spine injuries, the cost-utility of PHSI is unclear. Our h...

purpose: to evaluate changes in graft steepness after graft refractive surgery (grs) and to discover influential factors and a coefficient to predict the amount of postoperative shift. methods: keratoconic patients with history of penetrating keratoplasty (pkp) who underwent grs due to high post-pkp astigmatism were included. changes in mean keratometry after grs were evaluated to find possible...
