Although headache is among the most common and costly disorders in primary care, our understanding of its direct impact on the quality of life of affected individuals is incomplete. While studies evaluating the role of headache on health-related quality of life and healthcare economics are starting to appear in the medical literature, the effect of pharmacotherapy in improving quality of life is only beginning to be studied. At present, studies evaluating health-related quality of life in patients with migraine who are undergoing treatment are limited to 3 agents: sumatriptan, flurbiprofen and diclofenac. Several studies have consistently indicated that these drugs benefit patients by improving key dimensions of health-related quality of life or patients' sense of well-being to a significant extent. Given the magnitude of functional and emotional impairment associated with chronic headache disorders, assessing patients' perceptions of their quality of life makes a useful contribution to the evaluation of therapeutic interventions and should supplement traditional clinical endpoints in determining the effectiveness of new drugs.  相似文献

Topoisomerase I (TOP I) and II (TOP II) activities and their corresponding levels were analyzed in 27 primary brain tumors and 32 lung cancers (28 NSCLC, 4 SCLC). The TOP I and II activities in primary brain tumors varied from 500-2,000 units/mg and 100-3,000 units/mg respectively. Their corresponding levels varied from <0.01-3.30 (TOP I) and 0.24-8.30 (TOP II) arbitrary units. In lung cancer, the TOP I and II activities ranged from 1,000-4,000 and 500-4,000 units/mg respectively with their levels ranging from 0.30-61.60 and 0.2-14.2 arbitrary units respectively. These parameters were compared in both tumors using the Wilcoxon rank sums test, the difference were statically significance for all four parameters with a p<0.0001 for TOP I and II activities and TOP I levels and p<0.09 for TOP II levels. Using linear regression analysis, there was no correlation between TOP I and II activities and their corresponding levels in primary brain tumor. However, in lung cancer, the relationship between TOP I activities and levels were linear with r(2)=0.2 and p<0.0094, but not for TOP II activity and their levels. There was no relationship between TOP I and TOP II levels in the same tumor for both types of cancer. The future clinical implication of these findings are discussed.  相似文献

Notions of racial superiority created population control policies. White men defined overpopulation as the root of development problems (e.g., from poverty to political instability) in developing countries and decided to solve it themselves. This notion was accepted without resistance. Governments decided to persuade or coerce women to have fewer children instead of improving living conditions. Since no basic health care system existed in these countries, decision makers delivered Western contraceptive technologies. Hormonal contraceptives and IUDs were heavily promoted, but inadequate back-up services to treat side effects or monitor use existed. Barrier methods, which prevent sexually transmitted diseases, were not promoted. Pregnancy prevention was more important than safety. Women had no control over their own fertility. Views of Margaret Sanger, a pioneer of the birth control movement, formed the foundation for more aggressive laws based on eugenics. The American Birth Control League advocated racial progress and sterilization. Large organizations initiated contraceptive research. Later public institutions took over contraceptive research that focused on female methods because the field was dominated by males. Developing countries depend on the US Food and Drug Administration (FDA) rulings to develop their own guidelines on contraceptives. The pharmaceutical industry weakens FDA'S resolve. It considers developing countries to be a huge expanding market. The Western attitude that family planning is much safer than childbearing punishes the poor for their poverty and disregards long-term risks to women. Providers do not always inform women about risks of contraceptives. The sterilization program in India was based on restricted choice, coercion, targets, and incentives. Success stories include Cuba, South Korea, Sri Lanka, and Kerala State in India. Expansion of basic health care and improvement of the general condition of people's lives are needed.  相似文献

The Working Alliance Inventory was used to measure the strength of the therapeutic relationship between seriously mentally disabled case management clients and their case managers in a randomized trial of consumer-provided case management services. It was found that while there was no difference in the strength of the alliance between the consumer and nonconsumer teams of case managers, there were positive relationships between alliance and some outcomes, including quality of life, symptomatology, attitudes toward medication compliance, and satisfaction with mental health treatment.  相似文献

This article reports the results of a randomized trial of a team of case managers who are mental health consumers compared to a team of nonconsumer. Using a repeated measures MANOVA design, consumer case managers were found to be as effective as a team of nonconsumer case managers in maintaining the stability of severely mentally disabled clients served over a 2-year period. Implications for the employment of consumers in mental health services and the vocational capacity of persons with mental illness are discussed.  相似文献

Videodensitometric analysis of myocardial contrast echocardiography is traditionally performed off line. Recently, an online contrast ultrasound analysis system, Acoustic Densitometry (Hewlett-Packard), was introduced. We compared pixel intensities acquired with Acoustic Densitometry to pixel intensities derived from videodensitometry. A tissue phantom was imaged in phase I using three transducer frequencies (2.5, 3.5, and 5.0 MHz). In phase II, an in vitro flowing tube model with various concentrations of Albunex® was imaged at two flow rates, 0.6 and 1.2 m/sec, and at two transducer frequencies, 2.5 and 3.5 MHz. The relationship between pixel intensities yielded by the two systems for identical ultrasound signals was determined with linear regression. Intensities derived with Acoustic Densitometry strongly correlated with those derived from the offline videodensitometry system. The intensities were related by a predictive multiplicative factor based on display characteristics of the two systems. These results suggest that semiquantitative, online perfusion analysis with Acoustic Densitometry is as sensitive as analysis offline with videodensitometry.  相似文献

Purpose

The aim of this clinical report is to describe a case of unintentional intraoperative awareness during sufentanil anaesthesia in a patient undergoing elective aortocoronary bypass grafting.

Clinical findings

After premedication with morphine (5 mg) and scopolamine (0.2 mg), this 51-yr-old woman received sufentanil (10 μg · kg?1), midazolam (4 mg) and isoflurane (0.3–0.4% end-tidal). The patient recalled specific events and discussions which took place in the operating room during surgery. This patient’s report was clear and corroborated by operating room personnel. The patient denied having felt pain, anxiety or emotional distress.

Conclusion

Although awareness during opioid anaesthesia has been previously described with morphine and fentanyl, as far as we know this is the first clinical report of awareness with sufentanil. Given that recent efforts of early extubation in cardiac surgery patients may involve a reduction in the amount of opioid administered, this report serves as a reminder of the ever present potential for this disturbing complication.  相似文献
