Abstract
Background: This work attempted to define the care and course of those most severely affected patients in the setting of blunt chest trauma,
who had hypotension refractory to routine fluid resuscitation.
Methods: Twenty-three critically ill blunt trauma ICU patients were resuscitated and enrolled with ongoing hypotension required placement
of a pulmonary artery catheter. The REF?Explorer (Baxter, Edwards, Anaheim, CA) catheter was placed in the right heart measuring pressure, volume and oxygen utilization
information, as well as recording Injury Severity Score, EKG, CXR, CPK/MB and echocardiography over the initial 72-h time
period.
Results: There were an approximately 2,300 Level I trauma patients admitted annually over a 4-year period with an overall mortality
rate of 4.3% (100) patients with 3.4% (79) patients “ruling in” with elevated cardiac enzymes, associated with an increased
mortality rate of 6.7% (p < 0.05). The 23 patients were male (17, 74%), mean age 41.2 years, with no past medical history
(19, 83%), in a motor vehicle accident (21, 91%), with pulmonary injury (9, 39%), undergoing celiotomy in (10, 44%). They
presented with moderate to severe trauma acuity defined as mean GCS of 8.6, TS of 11.3, and ISS of 34 with an increased mean
hospital stay of 15 days versus 6 days in the ICU; and a 26 days versus 10 days overall stay for those with myocardial contusion
(p < 0.05). Analysis of diagnostic variables found an abnormal EKG in (21, 91%), CXR in (20, 87%) and echocardiogram in (8,
37%). The total CPK was found to be elevated, mean 2,219 (204–8,278 U/l), while the MB fraction was normal 2.3 ± 1.3%. Invasive
cardiac monitoring found an increase in CO of 1.6 l/min from 5.9 to 7.8 l/min during the first 24 h of recovery. Survival
was worsened with increased ISS (29 vs. 43) p < 0.02, but improved with longer ICU (17 vs. 8) p < 0.03 and hospital (39 vs.
7) p < 0.05 stay in days. The analysis of commonly used diagnostic modalities – EKG, CXR, ECHO, or CO, did not correlate with
survival, but the total CPK was increased in survivors (2,715 vs. 1,432 U/l) p < 0.009.
Conclusion: There is worsened morbidity with a 2-fold increase in ICU LOS and hospital stay, and a 1.5-fold increase in mortality in the
severe myocardial contusion group. The diagnostic dilemma posed by lack of definitive testing continues unresolved after analysis
of routinemodalities – EKG, CXR, ECHO, CPK or CO – failing to yield a “best test”. 相似文献

Background
Neck skin is thinner and has a more delicate dermal layer than facial skin. The studied product was specifically formulated for the neck combining a hydrating delivery system with a trifunctional corrective technology composed of 0.2% pure retinol, 2.5% tripeptide concentrate, and 5.0% glaucine complex to help improvement in signs of aging.Objectives
To evaluate cosmetic and histologic changes 3 months after treatment using immunostains for Type I collagen, Type III collagen, and glycosaminoglycan (GAGS). In addition, overall clinical improvement in photoaged skin was measured by both Griffith's photonumeric photoaging scale, photographic improvement, and questionnaires.Methods
This study was an open-label, blinded clinical trial evaluating a combined retinol, tripeptide, and glaucine containing cream in the treatment of photo-aged skin. The study enrolled a total of 20 healthy male or female subjects, who applied the product for 3 months to their face and neck.Results
Clinical as well histologic changes were consistent with improvement in all 20 subjects.Conclusion
Use of a combined retinol, tripeptide, and glaucine containing cream led to both clinical and histologic improvement of phototoaging. 相似文献124.

Introduction
Acne is the most common reason for dermatology consultation in adolescents and young adults. Consultation is often delayed despite unsuccessful self-treatment. Postponing effective treatment places acne sufferers at higher risk for permanent acne scars and post-inflammatory pigment changes.Aim
This review discusses clinical challenges with present therapeutic options for acne treatment and the role of a 1726 nm laser for acne.Methods
Current acne treatment guidelines were reviewed. A literature review was conducted for trials of light-based acne therapy. The selectivity of previous light-based therapies was reviewed.Results
Available acne therapy is effective, but treatment-related side effects are common. Acne treatment guidelines do not include recommendations for light-based treatments. Different types of light-based treatments have been tried but until now no wavelength specifically targeted sebaceous glands.Conclusion
The 1726 nm laser is safe and effective for treating mild to severe acne in all Fitzpatrick skin types. Acne resolution is apparent within the first month and improves for up to 2 years beyond treatment. 相似文献126.

Background
There is an increasing demand for facial skin rejuvenation. Specialized aesthetic skincare treatments may be one of the first steps to help prevent or treat facial signs of aging. This article discusses aesthetic skin care for facial skin rejuvenation, particularly data on two creams containing Macrocystis pyrifera ferment.Methods
The authors convened a dermatology advisory board to discuss challenges and practices in using skincare for facial rejuvenation, combining their expert opinion and experience on facial rejuvenation with preclinical and clinical data on two creams containing Macrocystis pyrifera ferment and a review of the literature.Results
Preclinical and clinical studies on Macrocystis pyrifera ferment and two creams containing the ferment exhibit anti-inflammatory, anti-aging, and healing properties. In preclinical studies, the ferment demonstrated collagen type I enhancing properties in ex vivo skin models, and skin cells treated with the ferment migrated faster than untreated cells in the in vitro study. In clinical studies measuring visible anti-inflammatory activity, the ferment alone and the ferment-containing products significantly decreased erythema, and in anti-aging studies, they improved visible skin aging parameters. Finally, in clinical studies on the stratum corneum, the two creams increased moisture levels and decreased transepidermal water loss (TEWL), reflecting healing by enhancing barrier strength and recovery.Conclusions
The Macrocystis pyrifera ferment and creams containing the ferment are effective skin care treatment products to decrease the visible effects of inflammation and signs of aging while promoting healing by enhancing barrier resilience and recovery. 相似文献127.

An emerging role for nurses is that of expert witness for medical liability cases that involve nursing care. Medical liability cases require that the trier of evidence (judge or jury) have an understanding of the facts and the relevant standards of the case for equitable resolution. The attorney, judge, or jury member may not possess the information necessary to understand the issues. Someone with the requisite knowledge and skills to review the information, interpret facts, offer an opinion about whether or not the standard of care was met, and explain this to the appropriate people is crucial for the legal system to work. If nursing care is at issue, that expert is a nurse with the appropriate knowledge, experience, and education. This report explores the role, qualifications, and expectations for nurses who serve as expert witnesses. Personal insights from the authors will provide practical information for nurses who are interested in the role. Copyright © 2001 by W.B. Saunders Company 相似文献
