Urologic complications following renal transplantation: role of interventional radiologic procedures 总被引:1,自引:0,他引:1
Bennett LN; Voegeli DR; Crummy AB; McDermott JC; Jensen SR; Sollinger HW 《Radiology》1986,160(2):531-536
Seventy renal transplant recipients with suspected urologic problems underwent interventional radiologic procedures for further diagnosis and treatment. We found that 28 patients did not have urologic complications. The other 42 patients demonstrated a total of 62 complications, including 40 cases of obstruction, 12 cases of extravasation, and ten collections of pararenal fluid. Ultrasound and nuclear renal scans with both technetium-99m DTPA and iodine-131 hippuran were found to be sensitive screening techniques for the detection of these complications. Fifty of the 51 abnormalities were detected using a combination of these techniques. Percutaneous methods alone were successful in treating 15 urinary obstructions, eight pararenal fluid collections, and five urinary extravasations. We encountered six procedure-related complications, and there were three delayed infectious complications that were related to indwelling nephrostomy tubes. One of these three complications resulted in death. The results of our study suggest that invasive radiologic procedures can be safely used to diagnose and treat urologic complications in renal transplant recipients. 相似文献

Crossover use of donated blood for autologous transfusion: report of the Council on Scientific Affairs, American Medical Association 总被引:1,自引:0,他引:1
BACKGROUND: Controversy exists concerning whether the costs and potential risks outweigh the potential benefits of "crossover" use in the general blood supply of unutilized blood that was donated for autologous transfusion. STUDY DESIGN AND METHODS: Published articles and reports were identified through systematic search of MEDLINE and review of references cited in previously identified articles, textbooks, and reports. Consultation was made with experts in blood donation and transfusion. Additional peer review was received from the American Medical Association (AMA) Council on Scientific Affairs RESULTS: Concern over infectious disease transmission has led to increased interest in and support for autologous transfusion for individuals having planned surgeries. Different requirements exist for collection, labeling, and screening of blood to be used for autologous versus allogeneic transfusions; therefore, procedures for diverting autologous blood donations to the general blood supply involve considerable expense. Several cost-effectiveness studies of autologous blood donation and transfusion conclude that currently this "crossover" appears to be an expensive procedure yielding little increased benefit from a societal perspective. CONCLUSIONS: The recommendations in this report were adopted as AMA Policy at the AMA Annual Meeting in June 1997. The AMA does not encourage blood collection programs to "cross over" units donated for autologous use to the allogeneic blood supply. Practice guidelines are needed, and should be utilized to ensure parsimony in the use of autologous blood donations and transfusions. 相似文献

Pattern reversal visual evoked potentials in children with migraine or tension-type headache 总被引:1,自引:0,他引:1
LN Rossi GC Pastorino G Bellettini A Chioci E Mariani I Cortinovis 《Cephalalgia : an international journal of headache》1996,16(2):104-106
Pattern reversal visual evoked potentials were recorded in 71 children with different types of migraine (e.g. migraine with aura, migraine without aura) or tension-type headache and in 19 controls (mean age of both groups 9 years). P100 latencies were comparable in all three groups. 相似文献

BACKGROUND
Many state agencies have developed model wellness policies (MWPs) to serve as examples for schools when writing their own school wellness policy (SWP). The purpose of this study was to evaluate if a MWP aids schools in writing stronger, more comprehensive SWPs.METHODS
For this cross‐sectional study, 91 school districts submitted their current SWP and completed a survey that classified districts into either districts that utilized the state MWP (N = 56; 61.5%) or those that did not (NMWP, N =35; 38.5%). The Wellness School Assessment Tool (WellSAT) was used to assess the strength, comprehensiveness, total overall score, and subsection scores of each policy. Dependent variables were compared between groups using t tests. Statistical significance was set at p ≤ .05. Data are presented as mean ±SD.RESULTS
No significant differences were found between groups in total overall (MWP 76.8 ± 37.9; NMWP 62.1 ± 34.3), strength (MWP 25.3 ± 17.6; NMWP 19.1 ± 12.8), or comprehensiveness scores (MWP 51.5 ± 21.2; NMWP 43.0 ± 22.1). The only subsection score difference identified between groups was the Nutrition Standards comprehension score (p = .02).CONCLUSIONS
These data suggest MWPs may not improve the quality of written SWPs. Further research is needed to better understand the needs of school districts in SWP development.88.

Background Adnexal torsion is rare, and symptoms are nonspecific. Clinicians often rely on US examinations to evaluate girls with abdominal
or pelvic pain.
Objective To determine which sonographic findings can predict adnexal torsion by comparing pediatric and adolescent patients with surgically
confirmed torsion (cases) to those without torsion (controls).
Materials and methods Cases and controls were identified retrospectively by searching 7 years of medical record and radiology databases. An adnexal
ratio was calculated as the volume of the affected adnexa divided by the volume of the unaffected adnexa.
Results We identified 61 menarchal subjects: 33 cases and 28 controls. Adnexal volume was larger in cases than in controls (185 vs.
37.8 ml, P < 0.001). A volume of >75 ml was more common in cases than in controls (64 vs. 15%, P < 0.001). No cases had an adnexal volume of <20 ml (P < 0.001). The adnexal ratio was larger in cases than in controls (16.1 vs. 6.7, P < 0.001). An adnexal ratio of >15 was seen in 40% of cases and in no controls (P = 0.08). Doppler US results were not predictive of torsion.
Conclusion An adnexal volume of <20 ml is strong evidence against adnexal torsion in menarchal females. In this age group, the diagnosis
of torsion cannot be established by US examination alone. 相似文献

胃癌中微卫星不稳定性及DNA错配修复系统 总被引:1,自引:1,他引:0
1993年Altonen[1]首次发现遗传性非息肉病性大肠癌(herediary nonpolyposis colorectal cancer,HNPCC)细胞中存在高频率微卫星不稳定性(MSI)以后,许多学者相继发现在多种肿瘤中存在着微卫星不稳定性[2-6].DNA错配修复系统的发现,使微卫星不稳定性的起源得到深入的研究.近年来胃癌中微卫星不稳定性及其可能的致癌机制成为研究的热点,东西方学者由于地域、人群及研究的方法不同,对此研究存在不少争议[7-15]. 相似文献
