a 15- year-old boy with history of bb gun injury to his left eye was referred to our center. his visual acuity was no light perception in the left eye. ocular findings were severe proptosis, conjunctival injection, and conjunctival vascular tortuosity. fundus examination revealed an extensive inferior chorioretinal scar compatible with chorioretinitis sclopetaria. a distinct bruit was detected ...

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...

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...

BACKGROUND There exists a great variety of liver parenchyma transection techniques. The objective of this research is to develop a new method of liver transection, and to compare it with the traditional ones. METHODS An original gas jet transection method of biological tissues and the apparatus "Pneumojet" to make the method practicable were developed in our institute. Comparison between the ...

Spinal cord injury (SCI) severely disrupts bladder function. What mediates bladder dysfunction after SCI is currently unknown. We investigated the role that primary afferent sprouting in lumbosacral cord may play in emergence of bladder activity after complete spinal cord transection. Rats had a bladder cannula chronically implanted. They were then subjected to complete surgical spinal cord tra...

Ten children, aged 4 to 14 years, sustaining blunt arterial trauma from motor vehicle collisions (6), bicycle accidents (2), and falls (2) were identified over a 10-year period. The arteries injured included the common iliac (3), abdominal aorta (2), carotid (2), brachial (2), and the subclavian, renal, and femoral artery (1 each). One patient had three arterial injuries. Six patients had assoc...
