The objectives of this study were to evaluate the reliability of herpes simplex virus (HSV) PCR testing in cerebrospinal fluid (CSF) for the detection of herpes simplex encephalitis. This was done by examining retrospectively the clinical follow-up of a large group of patients tested routinely by HSV-PCR. In addition, an attempt was made to assess the incidence of herpes simplex encephalitis in a central European population. CSF samples from 1,427 patients from all Vienna hospitals were submitted for HSV-PCR testing during a period of 4 years and 8 months. Herpes simplex encephalitis was detected by PCR in 12 cases and by serological methods in one additional patient. Retrospective analysis of the course of disease, which was possible in 799 PCR-negative patients, led to the identification of three additional cases in which herpes simplex encephalitis appears to have occurred despite negative PCR results. Failure of the PCR in these patients is most likely due to the time of obtaining CSF during the course of disease. A high specificity of the assay was demonstrated by the lack of false positive results in any of the 708 cases in which other causes for the neurological symptoms had been identified in the follow-up. The incidence of herpes simplex encephalitis in the population of Vienna was between 1 case/469,000-577,000 individuals/year. The highest annual incidence was detected in the age group between 3 months and 3 years, which, however, could not be confirmed statistically. 相似文献

Experimentally induced neuronal dysfunction in respiratory regions of the rostral medulla decrease breathing more in anesthetized mammals than in awake mammals. Sleep is similar to anesthesia in that excitatory inputs to respiratory neurons are reduced compared to the awake state; thus, we hypothesized that neurotoxic lesions in rostral medullary nuclei would, relative to wakefulness (WK), induce and/or accentuate hypoventilation during non-rapid eye movement (NREM) sleep. To test the hypothesis, goats were studied between 21:00 h and 03:00 h: (1) before and 30 days after chronically implanting microtubules bilaterally into the rostral medulla and, (2) 9-15 h and 2-17 days after unilateral injections of 100 nl to 1 microl, 50 mM ibotenic acid into the vestibular, gigantocellularis reticularis, or facial nuclei, or the retrotrapezoid nucleus/parapyramidal region. Arterial blood was repeatedly sampled in all studies during WK, and NREM and rapid eye movement (REM) sleep states. There was no significant (P>0.10) change in Pa(CO(2)) between WK and NREM sleep (and REM sleep when sufficient data were obtained) before or after implantation of microtubules and in studies after creating the neurotoxic lesions. Breathing frequency also did not significantly (P>0.10) differ between states in any of the studies. The data thus did not support the hypothesis. We speculate that in goats efficient compensatory mechanisms maintain Pa(CO(2)) homeostasis during normal sleep and the same and/or other mechanisms maintain homeostasis when excitatory drive is further reduced by lesions in rostral medullary nuclei. 相似文献

Six patients with intractable spasms after spinal cord injury underwent implantation of an epidural spinal cord stimulation system. All the patients experienced good relief postoperatively. In three patients spinal cord stimulation consistently produced immediate inhibition of the spasms. This was evident within less than 1 minute of stimulation. Conversely, the spasms reappeared within less than 1 minute after cessation of the stimulation. The clinical observations were confirmed by polygraphic electromyographic recordings. 相似文献

A retrospective analysis of the efficacy of a variety of external stabilization techniques used in 155 cases of unstable cervical spine injuries is presented. The movement at each intervertebral level was evaluated during thermoplastic Minerva body jacket stabilization in 18 additional patients. Many currently available approaches to external stabilization of the cervical spine were, thus, assessed. Thermoplastic Minerva body jacket stabilization offered superior segmental immobilization compared with published data for the halo. It is concluded that some unstable injuries to the high cervical spine might best be treated with a halo device, whereas mid to low cervical injuries and the remaining upper cervical spine injuries appear to be optimally treated with a Minerva jacket. Lesser injuries may be treated with a variety of available orthoses. The thermoplastic Minerva body jacket offers a superior limitation of intervertebral movement compared with other commonly used braces, including the halo jacket, for most cervical spine injuries. The technique of application of the thermoplastic Minerva body jacket is reviewed. 相似文献

Health related quality of life (HRQOL) has become an important re- search topic in dermatology. We developed a series of modular, dermatology-specific HRQOL questionnaires: the Freiburg Life Quality Assessment (FLQA). Each FLQA questionnaire consists of a core module (FLQA-c) applicable to all skin diseases plus a number of items specific to distinct dermatological diseases. The objectives of the present study were: 1) to test the psychometric properties of the FLQA-c, and 2) to define a threshold indicating a significantly reduced HRQOL. 394 psoriasis patients, 253 atopic dermatitis patients, and 240 control subjects completed the FLQA-c. Cronbach's alphas were above 0.75 for all six scales except for "treatment". Discriminant validity, sensitivity to change, and convergent validity were satisfactory. On the different scales, the threshold indicating a marked reduction in HRQOL detected 33% to 68% of the patients. These data support the reliability and validity of the FLQA-c. 相似文献

Experimental panic induction with cholecystokinin tetrapeptide (CCK-4) is considered as a suitable model to investigate the pathophysiology of panic attacks. While only a few studies investigated the brain activation patterns following CCK-4, no data are available on the putative involvement of the amygdala in the CCK-4 elicited anxiety response. We studied the functional correlates of CCK-4-induced anxiety in healthy volunteers by means of functional magnetic resonance imaging (fMRI) and region of interest (ROI) analysis of the amygdala. Sixteen healthy volunteers underwent challenge with CCK-4 compared with placebo in a single-blind design. Functional brain activation patterns were determined for the CCK-4-challenge, the placebo response and anticipatory anxiety (AA). CCK-4-induced anxiety was accompanied by a strong and robust activation (random effects analysis, P < 0.00001, uncorrected for multiple testing) in the ventral anterior cingulate cortex (ACC), middle and superior frontal gyrus, precuneus, middle and superior temporal gyrus, occipital lobe, sublobar areas, cerebellum, and brainstem. In contrast, random effects group analysis for placebo and AA using the same level of significance generated no significant results. Using a more liberal level of significance, activations could be observed in some brain regions such as the dorsal part of the ACC during AA (random effects analysis, P < 0.005). Overall functional responses did not differ between panickers and nonpanickers. Only 5 of 11 subjects showed strong amygdala activation. However, ROI analysis pointed towards higher scores in fear items in these subjects. In conclusion, while overall brain activation patterns are not related to the subjective anxiety response to CCK-4, amygdala activation may be involved in the subjective perception of CCK-4-induced fear. 相似文献
