The occurrence of pericapillary fibrin in venous hypertension and ischaemic leg ulcers: a histopathological study.

The presence of pericapillary fibrin and complement C3c in the ulcers of 19 patients with venous hypertension and 14 patients with ischaemic leg ulcers was investigated using histochemical and immunohistochemical techniques. There was deposition of fibrin around the capillaries in the central part of the ischaemic ulcers, and the venous hypertension ulcers, and in the non-ulcerated skin around one of the venous hypertension ulcers and two of the ischaemic leg ulcers. The deposition of fibrin is a secondary phenomenon that occurs in the area of ulcerated skin and does not play a major causal role in the formation of chronic leg ulcers.

Movements causing ankle fractures in parachuting.

The parachutist injured in a dramatic accident often describes the injury in an incomplete and biased way and evaluation of materials based solely upon subjective information of this kind can be misleading and of no value for recommendations. As the relation between the mechanical factors of the injury and the lesion in ankle fractures is well documented, an investigation of clinical, radiological and operative findings in 46 parachutists with ankle fractures was conducted. Classification was possible in 44 of 46 fractures. The description of the cause of the trauma in 21 supination-eversion fractures and in 13 pronation-eversion fractures was most frequently faulty landing position or obstacles. The cause of seven supination fractures was oscillation of the parachutist whilst descending with sudden impact against the lateral aspect of the foot. For prophylaxis we recommend improvement of landing and steering techniques and the support of semi-calf boots.
