Age correlation in the bulbo-cavernosus reflex.

A study was conducted in 120 normal male subjects (age range 15-20 years) by testing the bulbo-cavernosus reflex (BCR). The mean latency +/- SD of the reflex was 32.9 +/- 0.7 ms. BCR latency values reported in subjects grouped according to age (15-20, 21-30, 31-40, 41-50, 51-60, 61-70) did not vary significantly for individuals between the ages of 15 and 50; whereas, the latency values for the older age groups (5th and 6th groups), were statistically significant. In conclusion, the authors attribute the increased latency associated with age to changes which occur in the fibres of the nerve pathways and emphasize the importance of collecting normative data according to age groups.

[Uremic neuropathy and the type of dialysis].

Motor conduction velocity of the median and posterior tibial nerves and sensory conduction velocity of the radial and sural nerves were examined in 45 uremic patients: 15 treated by hemodialysis (HD), 15 treated by combined peritoneal dialysis (CPD) and 15 treated as outpatients with peritoneal dialysis (CAPD). Motor and sensory conduction velocity were reduced in uremic patients treated by HD more than in those treated by CPD and CAPD; there were no significant differences between the last two groups.

Changes in auditory P3 event-related potentials in uremic patients undergoing haemodialysis.

A study on event-related P300 potential (ERPs) was performed in 20 patients suffering from chronic uraemia and undergoing haemodialysis in order to assessing the functioning of their cognitive processes. The patients were evaluated before and after a standard treatment of haemodialysis. The P300 potential was studied by means of the "oddball" paradigm and the acoustic modality. Moreover the patients' performance was assessed on the basis of the following psychological tests: the Mini Mental Test, the Number Connection Test and the Digit Span of the Wechsler Adult Intelligence Scale. A significant improvement in the P3 latency was demonstrated following the dialysis treatment. Even though a slight improvement in the N2-P3 deflexion amplitude was recorded after dialysis, it was not statistically significant. These data indicate a positive modification in the speed of the cortical function as a consequence of dialysis. These results suggest that the P3 latency obtained from auditory stimuli can help to assess the benefits obtained through extracorporeal dialysis, especially in the follow-up to the illness.
