Systemic inflammatory response syndrome (SIRS) is a non-specific exaggerated defense caused by infectious or non-infectious stressors such as trauma, burn, surgery, ischemia and reperfusion, malignancy, which can eventually lead to an uncontrolled response. In addition the early mortality due “first hits” after trauma-induced SIRS multiple organ dysfunction (MODS) are main reasons for poor prog...

Pediatric abusive head trauma – once commonly known as the shaken baby syndrome – is a form of child abuse that results in traumatic brain injury. The peak incidence of pediatric abusive head trauma appears to be in children between the ages of 2 to 4 months; the exact incidence of this injury is not known. Pediatric abusive head trauma often results in severe and permanent neurological damage,...

Rothmund-Thomson syndrome is a rare autosomal recessive genodermatosis characterized by a poikilodermatous rash starting in infancy as well as various skeletal anomalies, juvenile cataracts, and predisposition to certain cancers. Although Rothmund-Thomson syndrome is associated with diminished bone mineral density in addition to multiple skeletal abnormalities, there are few reports of the asso...

Marfan syndrome is an autosomal dominant and could decrease bone mineral density. So patients with Marfan syndrome could vulnerable to trauma in old ages. We present the first report, to the best of our knowledge, of a rare fracture of the femoral neck with a minor traumatic history in a juvenile Marfan syndrome patient whose physis is still open. Although the patient is young, her bone mineral...

This paper is about a posttraumatic distal ulnar artery thrombosis case that has occurred after a single blunt trauma. The ulnar artery thrombosis because of chronic trauma is a frequent condition (hypothenar hammer syndrome) but an ulnar artery thrombosis because of a single direct blunt trauma is rare. Our patient who has been affected by a single blunt trauma to his hand and developed ulnar ...

A case of classical Guillain-Barré syndrome following acute head trauma is described. The association of Guillain-Barré syndrome with head injury per se is not well recognized, and a possible immunological explanation is proposed.

Moyamoya vascular pattern and dural arteriovenous fistula (dAVF) are rare vascular abnormalities and both can be secondary to head trauma. The role of dural angiogenesis in the pathophysiology of vascular malformation is rather unclear. We report a unique case of moyamoya vasculopathy simultaneously associated with dAVF after heavy head trauma. It seems that both moyamoya syndrome and dAVFs are...

Six years experience of blunt abdominal trauma leading to small intestine Perforation in Logh­rnan-e-Hakim Medical center. Between Sept. 1982 to Sept. 1988, 24 cases of abdominal blunt trauma leading to perforation of small intestine were managed at Loghman-e-Hakim Medical center. All the cases were treated surgically either by debridment and repair or resection and anas­tomosis, with no mortal...
