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...

UNLABELLED The exposing of dental implant into the maxillary sinus combined with membrane perforation might increase risks of implant failure and sinus complications. OBJECTIVE The purpose of this study was to investigate the effects of the dental implant penetration into the maxillary sinus cavity in different depths on osseointegration and sinus health in a dog model. MATERIAL AND METHODS...

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...

background postoperative relapse is a common feature of crohn's disease (cd) in western countries but its frequency and risk factors have not been studied in the middle east where there is a rapid upsurge in the incidence of cd. this study aims to research the frequency and risk factors of its recurrence after surgery among 566 iranian patients with cd in tehran, iran. methods all 566 patients ...

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...

Abstract Although superhydrophobic materials have attracted much research interest in anti-icing, some controversy still exists. In this research, we report a cost-effective method used to verify the contribution of area fraction ice adhesion strength. We tried partially-embed silica nanoparticles into microscale fabrics commercial polyamide mesh. Then, could be determined by altering mesh size...

In this study, numerical modeling of a multi-drain system is employed to determine the optimum penetration depth of prefabricated vertical drains (PVDs) and the vacuum pressure that provides the maximum consolidation settlement and less lateral displacements. The plane strain analysis using an equivalent permeability with transformed unit cell geometry was considered for varying drain length an...
