Narcolepsy was diagnosed in 51 children (29 boys). The age range was 2.1 to 11.8 years (mean, 7.9 +/- 3.1 years). A mean of three referrals was made before narcolepsy was considered. ⋯ Teachers often refused to acknowledge a medical problem. During follow-up, all children presented at least once with depressive symptoms in reaction to their syndrome. Narcolepsy should be considered when evaluating children with behavioral and depressive symptoms.

Physiological characterization of Taxol-induced large-fiber sensory neuropathy in the rat.
The cancer chemotherapeutic agent Taxol (paclitaxel) causes a dose-related peripheral neuropathy in humans. We produced a dose-dependent large-fiber sensory neuropathy, without detrimental effects on general health, in mature rats by using two intravenous injections 3 days apart. Tests of other dosing schedules demonstrated the dependence of the severity of the neuropathy and of animal health on both the dose and the frequency of dosing. ⋯ The ability of rats to remain balanced on a narrow beam was impaired, indicating proprioceptive deficits. Muscle strength, measured by hindlimb and forelimb grip strength, and heat nociception, measured by tail-flick and hindlimb withdrawal tests, were not affected by Taxol. This model of Taxol-induced neuropathy in mature rats, with minimal effects on general health, parallels closely the clinical syndrome observed after Taxol treatment in humans.
