Two patients with arteriovenous fistulas of the native kidney occurring after needle biopsy were evaluated using duplex and color Doppler ultrasonography. The first patient had a fistula with associated pseudoaneurysm: color Doppler showed the lesion as a small rounded area with whirling flow; spectral analysis allowed recognition of both the afferent artery with low impedance flow and the draining vein with pulsatile, arterialized flow. The second patient had a normal color Doppler study; however, spectral analysis demonstrated signals with low vascular impedance from an intra-parenchymal artery at the lower pole, and a jet of turbulent flow. Following disappearance of clinical findings, such Doppler abnormalities were no longer detectable. When a iatrogenic arteriovenous fistula is considered on clinical grounds, both color and Doppler spectral analysis of waveforms from intra-parenchymal vessels should be performed. Possibly, further advances in color Doppler technology will permit the use of this examination as the first imaging procedure in these clinical situations.Correspondence to: L. E. Derchi 相似文献

Infective endocarditis is a result of infection of the endocardium, particularly of the heart valves (native or prosthetic valves). The most common causative organisms in the paediatric population are: Streptococci, Staphylococci and Enterococci. The classical signs of infective endocarditis like Roth spots, Janeway lesions, splinter haemorrhages and Osler's nodes are relatively rare in children. A high index of suspicion in a febrile child with a new murmur, detailed history, meticulous examination, repeated blood cultures, and echocardiography are essential in establishing the diagnosis. Management of infective endocarditis involves a prolonged course of antibiotics, at least for 4–6 weeks depending upon the causative organism and underlying heart condition. Complications of infective endocarditis include congestive heart failure resulting from valvular damage/regurgitation, infective emboli leading to abscesses in other organs and abnormal host immunological responses. Prophylactic antibiotics for dental and other medical procedures like genitourinary tract procedures are no longer recommended in the UK. The emphasis should be on educating children and their parents in early recognition of infective endocarditis. Children at high risk of developing endocarditis should be assessed urgently after clinical suspicion. 相似文献

ABSTRACT Empirically supported interventions (ESIs) for treating substance problems have seldom been made available to or tested with minority populations. Dissemination of ESIs may help reduce the disproportionate health disparities that exist. However, ESIs may require some adaptation to be effective with minority populations. One ESI, motivational interviewing (MI), appears to be particularly culturally congruent for Native American communities. We worked with Native American community members and treatment providers to adapt MI for Native communities. Reflecting their feedback and suggested amendments, we created and disseminated an intervention manual to improve the accessibility of MI within Native communities. To help guide practitioners working with Native American clients, we used focus-group methodology to explore communication patterns for negotiating change. Native American treatment providers expressed comfort with and enthusiasm for integrating MI into their current practices. Recommendations for adaptations ranged from simple to complex changes. The unique value and challenges of collaboration between academic and community members are presented from each author's perspective. This culturally adapted MI manual will likely improve the accessibility and adoption of MI practices as well as encourage controlled, clinical trials with Native communities. 相似文献

Objective. To encourage pharmacy students to elect education and practice opportunities in Native American communities, including careers with the Indian Health Service (IHS).Methods. Students in 2 elective courses were educated on various aspects of contemporary Native American life in urban and reservation environments, including cultural traditions, social and health-related challenges, health access disparities, and cultural approaches to health and wellness. The teachers were Native American leaders and healers primarily from Plains tribes, as well as non-Native American practitioners affiliated with IHS hospitals and tribal health facilities. Students kept reflective journals, and a subset spent 5 days immersed in a rural Navajo community where they lived and worked alongside IHS practitioners and Community Health Representatives.Results. Student engagement with IHS opportunities was tracked for 11 years. Of the 69 pharmacy students who completed the electives, 11 applied for a Junior Commissioned Officer Student Training and Externship Program (Jr. COSTEP) (8 accepted, 6 completed), 43 requested one or more IHS APPEs (43 accepted, 32 completed, 8 in progress), 17 applied for an IHS residency (1 pending, 8 accepted, 5 completed), and 5 became IHS Commissioned Corps officers. Five additional students accepted an IHS or tribal position, with 3 pursuing a USPHS commission.Conclusion. Since the first report on the impact of this elective experience was published, the course continues to meet its primary objective of promoting interest in IHS/tribal education experiences and pharmacy practice careers. 相似文献

Background: Drumming has been utilized among American Indian/Alaska Native (AI/AN) tribes for centuries to promote healing and self-expression. Drum-Assisted Recovery Therapy for Native Americans (DARTNA), currently under development, is a substance abuse treatment utilizing drumming as a core component. Objectives: Focus groups were conducted to assist in the development of the DARTNA protocol. Feedback obtained from these focus groups will inform a subsequent pretest of DARTNA and an empirical study analyzing its effectiveness. Methods: Three focus groups were conducted among AIs/ANs with substance use disorders (n = 6), substance abuse treatment providers (n = 8), and a community advisory board (n = 4) to solicit feedback prior to a pretest of the DARTNA protocol. Results: Overall, participants indicated that DARTNA could be beneficial for AIs/ANs with substance use disorders. Four overarching conceptual themes emerged across the focus groups: (1) benefits of drumming, (2) importance of a culture-based focus, (3) addressing gender roles in drumming activities, and (4) providing a foundation of common AI/AN traditions. Conclusions: The DARTNA protocol is a potentially beneficial and culturally appropriate substance abuse treatment strategy for AIs/ANs. In order to optimize the potential benefits of a substance abuse treatment protocol utilizing drumming for AIs/ANs, adequate attention to tribal diversity and gender roles is needed. Scientific Significance: Due to the shortage of substance abuse treatments utilizing traditional healing activities for AIs/ANs, including drumming, results from this study provide an opportunity to develop an intervention that may meet the unique treatment needs of AIs/ANs. 相似文献

Current forensic STR databases, such as CODIS, lack population genetic data on Native American populations. Information from a geographically diverse array of tribes is necessary to provide improved statistical estimates of the strength of associations with DNA evidence. The Globalfiler® STR markers were used to characterize the genetic structure of ten tribal populations from seven geographic regions in North America, including those not presently represented in forensic databases. Samples from the Arctic region, Baja California, California/Great Basin, the Southeast, Mexico, the Midwest, and the Southwest were analyzed for allele frequencies, observed and expected heterozygosities, and F-statistics. The tribal samples exhibited an FST or θ value above the conservative 0.03 estimate recommended by the National Research Council (NRC) for calculating random match probabilities among Native Americans. The greater differentiation among tribal populations computed here (θ = 0.04) warrants the inclusion of additional regional Native American samples into STR databases. 相似文献

Rock art in the Four Corners area often includes pictures of hands and feet, which may be representational or symbolic. There is correlation between actual metatarsal bones and carvings of polydactyl feet. No duplicated hand bones have been found, but we postulate petroglyphs of polydactyl hands are a reflection of a real congenital difference. 相似文献
