    Notes: Summary Microclectrode recordings of skin nerve sympathetic activity, consisting of sudomotor and vasoconstrictor signals, were performed in the peroneal nerve in seven healthy subjects during insulin-induced hypoglycaemia. The nerve activity was recorded at rest and for 90 min after intravenous injection of 0.15 IIJ insulin/kg body weight. The net outflow of skin nerve sympathetic activity was increased during hypoglycaemia, with the exception of one subject who exhibited a high initial level of activity. In all subjects a change of the temporal pattern of the outflow was found, suggesting a shift from mixed (sudomotor and vasoconstrictor) to pure sudomotor activity. This change coincided with a sensation of warmth, sweating and varying degrees of cutaneous vasodilatation, and was followed by a fall in body temperature. It is concluded that hypoglycaemia has a differential effect on sympathetic activity in skin nerves, with a strong increase of sudomotor impulses and simultaneous inhibition of vasoconstrictor signals. Thus, neurally mediated thermoregulatory adjustment contributes to heat loss during hypoglycaemia.

    Notes: Summary The effects of the aldose reductase inhibitor, sorbinil, on symptomatic symmetrical diabetic polyneuropathy were studied during a 6-month period in a double-blind parallel group placebo-controlled trial. Twenty-seven patients received sorbinil and 28 placebo. The patients were assessed by clinical examination, neurophysiological measurements, sensory threshold determinations and tests of autonomic nerve function. No major clinical benefit was seen in the sorbiniltreated patients and no differences in sensory thresholds were observed. In three out of nine neurophysiological tests (motor nerve conduction velocity of the posterior tibial nerve, F-wave latency and sensory distal latency of the ulnar nerve) and one out of five tests of autonomic nerve function (heart rate variation during deep breathing) significant differences between the patient groups evolved in favour of sorbinil treatment. An overall evaluation of the temporal development of these and remaining neurophysiological and autonomic variables suggested a small but significant benefit from sorbinil treatment. There was no evidence of continuing improvement throughout the treatment period and beneficial effects observed were no greater than those seen in previous trials of considerably shorter treatment periods. It is concluded that sorbinil treatment results in some improvement in peripheral nerve function in symptomatic diabetic polyneuropathy, but that the long-term effect may be of limited value.

    Notes: Summary Mixed haemagglutination and complement fixation tests were used to detect serum antibodies to peripheral nerve in 36 patients with acute Guillain-Barré syndrome. Twenty patients were treated with plasma exchange, 16 served as controls. A significant antibody titre was found in 19 patients with the haemagglutination test; 30 had complement-fixing antibodies. Patients lacking complement-fixing antibodies were less disabled at entry (P〈0.01). However, there was no correlation between the course of the disease and any of the antibodies in the two patient groups. The two tests were therefore not able to select patients for treatment by plasma exchange.
