The early pathological features of human diabetic neuropathy are not clearly defined. Therefore we quantified nerve fibre and microvascular pathology in sural nerve biopsies from diabetic patients with minimal neuropathy. Twelve diabetic patients underwent detailed assessment of neuropathy and fascicular sural nerve biopsy at baseline, with repeat(More)
The pathogenesis of diabetic distal symmetrical polyneuropathy (DSP) is poorly understood but there is some evidence that the disease process might extend beyond peripheral nerves. We used magnetic-resonance imaging to measure spinal-cord cross-sectional area in diabetic patients with and without DSP and in healthy controls. There were significant(More)
Charcot neuroarthropathy has been recognised for over 130 years and yet it remains a major cause of morbidity for patients with diabetes mellitus and a continuing challenge for physicians. It is rare but it seems to be increasing in prevalence and this provides hope that with larger studies it will soon be possible to clarify the natural history and optimal(More)
Tensor contractions are extremely compute intensive generalized matrix multiplication operations encountered in many computational science fields, such as quantum chemistry and nuclear physics. Unlike distributed matrix multiplication, which has been extensively studied, limited work has been done in understanding distributed tensor contractions. In this(More)
AIMS To follow-up patients with a 'sausage' deformity of the toe associated with local neuropathic ulceration to confirm the diagnosis of underlying osteomyelitis. This was based on our observation that some diabetic patients with suspected pedal osteomyelitis with a local neuropathic ulcer have a 'sausage' deformity of a toe. METHODS Over a period of 2(More)
Aims/hypothesis. Experimental studies have shown that abnormalities of nerve microcirculation are important factors in the pathogenesis of diabetic neuropathy but there have been few clinical studies. We have applied microlightguide spectrophotometry to measure intravascular oxygen saturation (HbO2%) and blood flow in human sural nerve. Methods. We studied(More)
Hypoglycaemia is common in people with diabetes who aim to achieve good blood glucose control. Severe hypoglycaemia presents with evidence of neurological dysfunction, such as inability to concentrate, confusion, seizures, and coma. Such disturbances are reversible on correction of the hypoglycaemia. Infrequently there may be a focal neurological deficit(More)
AIMS A progressive reduction in the area of foot ulcer on serial measurement is traditionally done by tracing the margin of the ulcer on a transparent film and counting the number of squares on a graph paper underneath. We set out to use and validate the measurement of foot ulcers using a digital imaging technique and compare this with the traditional(More)
The mechanism of neuropathic pain in the diabetic limb is far from clear. Phantom limb pain likewise is of obscure aetiology. The development of typical pain in an absent leg in a patient with diabetes many years after the amputation stimulates thought as to the mechanism, not only of neuropathic pain, but also of phantom limb pain. A 58-year-old man was(More)
Infection with rare organisms or at unusual sites occur more frequently in people with diabetes. If not recognised and treated promptly, morbidity and mortality are high in such cases. Here we report cases of necrotising fascitis, malignant otitis externa, Fournier's gangrene and psoas abscess occurring in diabetics that needed intensive treatment with(More)
