From two different specimens of a chronic prosthetic hip infection taken at an interval of 2 months a slow-growing gram-negative bacterium was isolated in pure culture. The strain grew with the typical features of a small-colony variant (SCV). 16S rRNA sequencing identified the bacterium as Escherichia coli. Biochemical characterization demonstrated(More)
BACKGROUND Uremic small-artery disease with medial calcification and intimal hyperplasia can lead to life-threatening skin necrosis or acral gangrene. It is a distinct complication of chronic renal failure that must be differentiated from soft-tissue calcification. An increased calcium-phosphate product and secondary hyperparathyroidism are the main(More)
Problem: The vascularity of the articular fragment is of key importance for the final outcome in three- and four-part fractures of the humeral head. Displacement of the articular segment may compromise the arterial blood supply to the humeral head and result in avascular necrosis. There is still controversy as to whether three- and four-part fracture(More)
This report is an analysis of 252 popliteal artery aneurysms (PAA) in 167 patients treated surgically at the University Hospital in Zurich during a 27 year period from 1965 to 1991. The predominance of male patients (95 percent) was consistent with that of other reports. PAA were bilateral in 51 percent of the patients and were associated with aneurysms at(More)
Four patients with hereditary lymphedema present at birth (Milroy's disease) have been studied by fluorescence microlymphography (1, 7). The videomicroscopy technique failed to visualize any lymphatic capillary in the edematous part of their legs. In sporadic primary lymphedema with late manifestation, however, a well developed superficial capillary network(More)
In the management of leg ulcers two aspects should be considered, i.e. the exact underlying condition (main cause and contributing factors) and local conditions. Concomitant peripheral arterial occlusive disease must systematically be excluded. Effective compression therapy (35 mmHg pressure at the distal calf) is the corner-stone in treatment of venous leg(More)
