Thirty patients completed a double-blind, randomized crossover study utilizing transdermal clonidine and an identical-appearing placebo. Crossover occurred at 6 weeks, with a total study time of 12 weeks. Subjects were asked to record daily in a special diary (1) the presence or absence of headache, (2) duration of headache, (3) severity of headache, and (4) use of pain medication for headache relief. The severity of the headaches was rated from 1 (very mild) to 5 (very severe). Although the subjects reported a decrease in frequency, duration, and intensity of headaches while using the medicated patch, these differences did not reach statistical significance. Nineteen patients subjectively preferred the medicated patch, while five preferred the placebo (P less than .01). During use of the medicated patch, a significant reduction (P = .039) occurred in use of class II narcotics. Three doses of these substances were used by the patients when treated with clonidine, while 34 doses were taken during placebo use. These findings suggest that clonidine might have a role in reduction of parenteral narcotic use in acute pain syndromes.  相似文献

BACKGROUND: Our aims in the present study were to estimate the influences of pain and urinary symptoms on quality of life, and to determine which of these two variables has the most predictive power with respect to quality of life in young men with chronic prostatitis-like symptoms. METHODS: Chronic prostatitis-like symptoms were measured by the National Institutes of Health-Chronic Prostatitis Symptom Index. Of the 28,841 men aged 20 years who lived in the study community, 18,495 men (a response rate 64.1%) agreed to participate in the study. A total of 1057 men who complained of symptoms indicative of chronic prostatitis were included in the study. The influences of pain and urinary symptoms on quality of life were determined using logistic regression analysis. The receiver operating characteristic (ROC) curve was used to estimate the predictive ability of each of these variables with respect to quality of life. RESULTS: Results from multivariate analysis showed that both pain and urinary symptoms were associated with an increased likelihood of impaired quality of life, although pain contributed more to a reduced quality of life than urinary symptoms. Relative to men who experienced mild pain, men who experienced moderate pain had a 3.9-fold risk of poor quality of life (odds ratio [OR], 3.87; 95% confidence interval [CI], 2.86-5.23; P < 0.001) and those who experienced severe pain had a 15.7-fold risk of reduced quality of life (OR, 15.68; 95% CI, 6.59-37.35; P < 0.001). Moderate urinary symptoms were associated with a 1.4-fold risk of bother (OR, 1.41; 95% CI, 1.01-1.99; P < 0.001) and severe urinary symptoms were associated with 2.4-fold risk (OR, 2.39; 95% CI, 1.37-4.12; P < 0.001), relative to mild urinary symptoms. Comparison of the effects of pain and urinary symptoms showed that pain severity had the most predictive power for bother, quality of life, and quality-of-life impact. The areas under the ROC curves for bother, quality of life, and quality-of-life impact were 71.3%, 69.3% and 72.5%, respectively. CONCLUSION: Urinary symptoms and pain might be associated with an increased likelihood of impaired quality of life in young men with chronic prostatitis-like symptoms. In addition, our findings suggest that pain severity is the most influential variable for determining quality of life in this population.  相似文献

Zusammenfassung Halbstrukturierte Inteviews mit 248 (ehemaligen) jüdischen Emigranten und Lagerh?ftlingen in Deutschland und drei Ziell?ndern der jüdischen Emigration zeigen, da? Erinnerungen an traumatische Erlebnisse im Nationalsozialismus in zahlreichen allt?glichen Kontexten auftreten und von zentraler Bedeutung für die Wahrnehmung der pers?nlichen Lebenssituation im Alter sind. Auf der Grundlage der Ergebnisse einer Pilotstudie zur Frage nach der subjektiven Gliederung des Lebenslaufs bei (ehemaligen) jüdischen Emigranten und Lagerh?ftlingen werden unterschiedliche Abschnitte der pers?nlichen Entwicklung nach dem Holocaust unterschieden. Selbsteinsch?tzungen der Untersuchungsteilnehmer zur Intensit?t von Erinnerungen an traumatische Erlebnisse in diesen Entwicklungsabschnitten unterstützen die Annahme, da? belastende Erinnerungen im Alter deutlich zugenommen haben. Die Untersuchungsteilnehmer unterscheiden sich erheblich in den Formen der Auseinandersetzung mit solchen Erinnerungen. Einige Untersuchungsteilnehmer reagierten mit Depressionen, Angstzust?nden, Gefühlen von überlebensschuld und Rückzug aus sozialen Beziehungen. Andere engagierten sich hingegen in hohem Ma?e in sozialen Beziehungen, vor allem zu Angeh?rigen der jüngeren Generation, um dadurch zur Vermeidung von Diskriminierung, Rassismus und Fremdenfeindlichkeit beizutragen.

A review of factors contributing to early mortality after cardiac transplantation revealed that up to 25 % of deaths were due to primary graft dysfunction unrelated to rejection or infection. In light of this finding, evaluation of a donor heart with regard to its suitability for transplantation takes on added importance. In an effort to screen the suitability of donor hearts in the region covered by the Northwest Organ Procurement Agency (USA), all donors are evaluated by two-dimensional transthoracic echocardiography as part of the initial evaluation. A total of 110 donor echocardiograms were reviewed and an attempt was made to correlate the 30-day outcome with the parameters measured. An unexpected finding was that the presence of left ventricular hypertrophy in the donor heart was associated with an increase in the incidence of donor heart dysfunction compared with donors with normal echocardiographic profiles (33 % vs 3 %, P = 0.007).
