A quasi-experimental study was conducted to evaluate the effect of preoperative interviews on patients' anxiety levels. A convenience sample of 60 was assigned between two groups of equal size: a treatment group in which subjects were interviewed by a perioperative nurse or a control group in which subjects were not interviewed. All subjects completed state-trait Anxiety Inventory questionnaires. Group comparison using analysis of covariance showed subjects who were interviewed by the perioperative nurse reported significantly less anxiety than control group subjects. 相似文献

BACKGROUND: We have seen several patients with itchy lichenified plaques located bilaterally on the elbows and/or knees and have named this condition 'psoriatic neurodermatitis' (PN). OBJECTIVE: The purpose of this study was to compare clinical and histopathological characteristics of these patients to those of patients with typical lichen simplex chronicus (LSC). METHODS: Nineteen patients with PN and 34 patients with typical LSC were included. Besides clinical dermatological evaluation, the prick test was carried out on 49 patients; the Phadiatop test on 40 patients; the patch test with European standard series on 47 patients; histopathological evaluation on 39 patients; and clinical psychiatric examination on 38 patients. RESULTS: Almost exclusively, PN was seen in females and was located on the extremities. It caused more plaques than typical LSC did. In PN, the plaques were smaller, sharper, more keratotic and less excoriated, and had fewer lichenoid papules around them. Itching was usually more severe in the evening, while resting and in a hot environment in typical LSC, but not in PN. In plaques of PN, microabscesses in the horny layer, hypogranulosis, regular acanthosis and thinning of the suprapapillary plates were more frequent, and hyperpigmentation in the basal layer was less. In patients with PN, depressive disorder was found more frequently; and generalized anxiety disorder or psychosomatic characteristics, less. There were no significant differences in the results of prick, Phadiatop and patch tests between patients with PN and those with typical LSC. CONCLUSION: In our opinion, it is most likely that the so-called PN is itchy psoriasis superimposed by LSC. 相似文献

Two organ recipients developed serologic evidence of syphilis infection after renal transplantation from a common deceased donor with a history of treated syphilis. Testing of donor serum for syphilis, which occurred after transplantation, gave results interpreted as consistent with past infection. However, subsequent serologic results in the recipients suggested transmission of infection at transplantation due to active infection of the donor. This may be explained by recent donor re-infection in view of the current syphilis epidemic in the United Kingdom. An initial error in the treatment of recipients further served to highlight unfamiliarity in managing this resurgent infection in the context of organ transplantation. 相似文献

Analysis of selenium content in commercial dietetic products 总被引:1,自引:0,他引:1
Selenium (Se) is largely associated with the protein component of foods. The processing of elemental feeds and artificial formulations used in clinical dietetic practice can, therefore, result in significant losses of Se from these products and the Se status of patients consuming these feeds may be compromised. A selection of commercial formulas typically used for enteral feeding, and for patients with cystic fibrosis, phenylketonuria and maple syrup urine disease were analysed for Se micro-fluorimetrically. Low Se contents were found in all food supplements except for Peptisorbon (0.09 mg Se/2000 kcal) and Clinifeed Protein Rich (0.08 mg Se/2000 kcal) which contained adequate daily Se levels according to the American RDI. The results show that a number of feeds are low in Se, especially those used for patients with cystic fibrosis and maple syrup urine disease. An investigation of the Se status of patients on these formulations may indicate the need for Se supplementation. 相似文献

Ten thrombocytopenic patients (platelets < 10–24 × 10(9)/L) who were refractory to platelet transfusion were investigated for their responsiveness to staphylococcal protein A column therapy. Nine patients had previously been treated with steroids, intravenous immune globulin, and/or other forms of immunosuppressive therapy without improvement in their transfusion response. All patients were receiving multiple platelet transfusions without achieving 1-hour corrected count increments (CCIs) > or = 7500. Eight patients had antibodies that reacted with platelets and were directed against HLA class I antigens, ABO antigens, and/or platelet-specific alloantigens. Plasma (500-2000 mL) from each patient was passed over a protein A silica gel column and then returned to the patient. Patients received from 1 to 14 treatments. A positive response to protein A therapy was defined as at least a doubling of the pretreatment platelet count and/or two successive 10- to 120-minute posttransfusion CCIs > or = 7500. Following plasma treatments, 6 of 10 patients responded with daily platelet counts that averaged 48 +/− 11 × 10(9) per L as compared with counts of 16 +/− 7 × 10(9) per L (p < 0.0005) before treatment. Posttransfusion CCI values determined in four of these patients averaged 2480 +/− 810 and 10,010 +/− 3540 (p < 0.005) before and after treatment, respectively. In contrast, among the four unresponsive patients, platelet counts averaged 10 +/− 9 and 13 +/− 10 × 10(9) per L (p = NS), respectively, while posttransfusion CCIs were 700 +/− 1410 and 1520 +/− 2460 (p = NS), respectively.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Publicity surrounding the salt and hypertension debate evoked fear in workers at a Salt Mine that their working conditions may lead to high blood pressure. A cross-sectional study was carried out to investigate the blood pressure levels of these workers. The blood pressure levels were found not to be raised in comparison with those of a similar group of workers not occupationally exposed to salt. 相似文献
