spinal cord injury (sci) leads to a significant health problem associated with a broad range of secondary complications and disabilities. in this regard, animal models can help us to understand the pathobiology of sci and evaluate the effects of potential treatments for sci. in contusion models of sci, different devices including surgical spring-loaded clips, balloons, forceps, weights and the ...

purpose: to report the first case of concomitant optic nerve transection and chorioretinitis sclopetaria patient and findings: a 12-year-old boy with history of bb gun injury to his right eye was referred for loss of vision 8 months after the accident. visual acuity in the right eye was counting fingers at one meter with 3+ rapd. on slit lamp examination, right eye seemed normal except 1+ anter...

A lthough the pancreas is not a common site of metastasis for renal cell carcinoma, it is the most common indication for pancreatectomy for metastatic disease. Metastatic disease may occur many years after nephrectomy (0.5-27 years in a recent article). Thompson and Heffess reviewed the combined English literature of 109 patients and reported that the interval between initial nephrectomy and pr...

Because of its variable origin and course, the thenar branch median nerve is at risk during carpal tunnel release. Transection results in atrophy non-functioning opponens pollicis, abductor pollicis brevis flexor muscles. A late neurorrhaphy hypothenar fat pad flap were performed to restore conduction thus muscle function after accidental transection an open release 216 days earlier. During eig...

OBJECTIVE Though a number of CT findings of bowel and mesenteric injuries in blunt abdominal trauma are described in literature, no studies on the specific CT signs of a transected bowel have been published. In the present study we describe the incidence and new CT signs of bowel transection in blunt abdominal trauma. MATERIALS AND METHODS We investigated the incidence of bowel transection in...

The process of cutting is analysed in fracture mechanics terms with a view to quantifying the various parameters involved. The model used is that of orthogonal cutting with a wedge removing a layer of material or chip. The behaviour of the chip is governed by its thickness and for large radii of curvature the chip is elastic and smooth cutting occurs. For smaller thicknesses, there is a transit...
