摘要： The bioterrorism-related anthrax outbreak generated unanticipated demand for dematologic services. In this study we sought to perform rapid, efficient, cost-effective evaluation of patients suspected of having cutaneous anthrax. During the outbreak, we developed an anthrax evaluation system featuring clinical field examination by nondermatologist physicians, followed by rapid referral of selected high-risk patients to a centralized dermatology center. We excluded anthrax in 29 previously screened high-risk patients. All were examined within 24 hours, costing ＄272.07 per patient. Diagnoses were established quickly (median, same day; range, 0-15 days). Among 2259 at-risk postal workers, 144 (6.4%) self-identified new (≤14 days) skin lesions and were examined in the field; 8 (5.6%) were referred to our system. Our system was not the only local dermatologic resource available during the outbreak. A system featuring initial nondermatologist examination with minimal laboratory evaluation, followed by rapid centralized referral of high-risk patients, functioned efficiently in this outbreak.

摘要： Objective: To characterise flash visual evoked potentials(FVEPs) in 20 patient s with Creutzfeldt-Jacob disease (CJD),and assess the relationships between spo ntaneous EEG patterns and the responses to individual stimuli. Methods: We analy sed the shape and time course of periodic sharp wave complexes(PSWCs) and respon ses to 1 Hz flashes. In nine patients, we applied an algorithm based on an autor egressive model with exogenous input (ARX) to estimate responses to individual r andom flashes and their interaction with PSWCs. Results:The FVEPs included P1 an d N1 components in all patients, and the P2 peak in 18. Eight patients showed gi ant FVEPs (N1-P2 > 60 V), all of whom had an MM polymorphism in codon129 of the prion protein gene; in seven cases, the presence of giant FVEPs correlated with a prominent and almost continuous periodic EEG pattern. Giant N1-P2 abnormally spread on the anterior scalp regions, and had a different waveform distribution from that of the PSWCs. In five patients with a normal or slightly enlarged ave rage N1-P2 amplitude, single sweep (ARX) analysis revealed a period of relative refractoriness following individual PSWCs. In four patients with‘giant’FVEPs, the individual responses occurred regardless of the interval between the stimul us and previous PSWC, but their amplitude had an inverse relationship with the i nterval ***: Giant responses to flash stimuli are a common findin g in CJD patients (40%of our cases). Single sweep ARX analysis showed that PSWC s were followed by a period of partial refractoriness, which prevented most of t he individual responses to flashes, but not giant FVEPs. The association between prominent spontaneous paroxysms and giant FVEPs suggests that both are due to a common hyperexcitable change favouring neuronal synchronisation. Significance: Our data contribute to clarifying the debated problem of the occurrence of giant FVEPs in CJD and their relationships with the spontaneous periodic EEG pat
