The aim of this study was to determine possible correlations between the clinical characteristics, electrophysiological features, and sonographic ulnar-nerve diameter in patients with ulnar neuropathy at the elbow (UNE). We prospectively performed clinical, electrodiagnostic, and sonographic studies in 102 patients having either purely sensory signs (35%)(More)
Because of the improved quality of peripheral bypass surgery, the role of isolated profundaplasty in revascularisation of the critically ischaemic limb has become very limited. This retrospective study of 72 isolated profundaplasties performed for critical limb ischaemia revealed a clinical improvement 1 year postoperatively of 39% in the period 1978-1983(More)
The weak signal obtained from the anomalous scattering (at lambda = 1.54 A) of naturally occurring elements such as sulfur, phosphorus and ordered solvent chloride ions is used to determine the atomic positions of these atoms. Two examples are discussed: the sulfur and chlorine substructure of tetragonal hen egg-white lysozyme and an oligonucleotide(More)
Benign paroxysmal positional vertigo is a common malfunction of the labyrinth, most frequently of the posterior canal, due to clot of debris in the endolymph. The attacks of vertigo are characterised by dependency on position, latency after positioning of the head, short duration, nystagmus, reversibility and fatiguableness. The diagnosis can be based on(More)
The influences of clinical factors, site of distal anastomosis, type of graft and angiographic run-off, on graft patency and limb salvage following 141 femorocrural and pedal bypasses in 121 patients were investigated retrospectively. The grafts consisted of 111 femorocrural and 30 pedal bypasses; 49% of the patients had diabetes mellitus. Venous grafts(More)
OBJECTIVE To determine the diagnostic value of high-resolution sonography in ulnar neuropathy at the elbow (UNE). METHODS Sonographic ulnar nerve diameter measurement was compared at three levels around the medial epicondyle with a criterion standard including clinical and electrophysiologic characteristics in a cohort of 123 patients presenting with(More)
