Detection threshold for percutaneous electrical stimuli: asymmetry with respect to handedness.
Sensory strength-duration curves were obtained using percutaneous true square-wave pulses ranging from 0.1 to 20.0 ms produced by an isolated constant current stimulator. In 119 healthy volunteers sensory thresholds were measured bilaterally by stimulating the distal phalange of the little finger. ⋯ Of right-handers tested 73.5% had a lower threshold on the left side while 70.8% of left-handers had a lower threshold on the right side. Although threshold asymmetry is associated with handedness this is not necessarily due to cerebral lateralization.

Pain in sciatica depresses lower limb nociceptive reflexes to sural nerve stimulation.
The inhibitory effects of acute pain produced by the Lasègue's manoeuvre on the lower limb nociceptive flexion reflexes induced by electrical sural nerve stimulation were explored in patients complaining of sciatica as a result of an identified unilateral disc protrusion. Lassègue's manoeuvre on the affected side produced a typical radicular pain and resulted in a powerful depression of nociceptive reflexes elicited either in the normal or in the affected lower limb. Simultaneously, patients reported relief of the electrically-induced pain. In contrast, painless Lasègue's manoeuvre on the normal side had no effect on these parameters.

Tuberculous meningitis: role of CT in management and prognosis.
Serial computed tomographic scans were performed during the course of tuberculous meningitis in 25 patients aged 1-70 years. Hydrocephalus rarely occurred without other abnormalities. Marked ventricular enlargement was associated with extensive basal enhancement. ⋯ Infarcts were much more common in children than in adults and were sometimes asymptomatic. Radiological abnormalities sometimes developed during treatment and often did not resolve completely. Many patients had severe residual neurological problems.

Case ReportsRestless red legs: an association of the restless legs syndrome with arborizing telangiectasia of the lower limbs.
Two patients are reported with Ekbom's syndrome of "restless legs" occurring in association with arborizing telangiectasia of the lower limbs. Sensory complaints have previously been reported in this skin condition but not described in detail. The co-existence of the two conditions is discussed in the context of previous explanations of the restless legs syndrome.
