吸入性损伤气管切开问题的临床讨论 总被引:10,自引:2,他引:8
目的:为了进一步探讨吸入性损伤病人的气管切开时机与指征。方法:回顾性总结分析了1981~1998年173例吸入性损伤的处理方法。他们中轻、中、重度吸入性损伤分别为94.53和27例,行气管切开57例。结果:全组死亡56例,病死率与烧伤情有一定关系,但主要死罪仍为吸入性损伤程度,24小时之内行气管切开病死率偏低。结论:中、重度吸入性损伤宜尽早衽气管切开治疗,并有预防意义。 相似文献

The neomycin phosphotransferase (neo) gene was transduced into murine hematopoietic stem cells by culturing a recombinant retrovirus- producing cell line in a Transwell (Costar, Cambridge, MA) (bottomed with a porous membrane) hung into a Dexter-type long-term bone marrow (BM) culture. Gene transduction into stem cells retaining long-term reconstitution ability was successfully performed by using protocols of total 15 to 18 days of culture including establishment of the Dexter culture, transduction, and G418 selection. In the irradiated recipients of these cells, a large majority of the BM, thymus, and spleen cells as well as peripheral blood (PB) leukocytes were of donor origin and the neo gene was present in these organs up to 21 weeks after cell transfer. One third to two thirds of the in vitro colony-forming cells in the BM of the recipient mice were resistant to cultivation with G418. It was further found that the hematopoietic system of secondary recipients given BM cells from a primary recipient mouse was predominated by original donor-type cells. The transduced neo gene was detected in the PB, BM, thymus, and spleen cells of these secondary recipients. These results indicate that our procedure of retroviral vector-mediated gene transfer is highly effective in safely introducing a gene into pluripotent hematopoietic stem cells. 相似文献

Background
A parasitological survey of Schistosoma haematobium and S. intercalatum infection among primary schoolchildren in capital area of Democratic Republic of São Tomé and Príncipe (DRSTP) was undertaken.Methods
Subjects with positive infection were confirmed by the detection of S. haematobium ova in the urine or S. intercalatum ova in the stool by using centrifugation concentration or merthiolate-iodine-formalin concentration method. Totally, 252 urine and stool samples, respectively, were obtained from apparently healthy schoolchildren, of which 121 from boys (9.8 ± 1.4 yr) and 131 from girls (9.7 ± 1.3 yr).Results
None of participating schoolchildren were found having S. haematobium ova in the urinary specimen. While, among 4 primary schools studied, only schoolchildren from Saint Marçal were detected with S. intercalatum ova in the fecal specimen, making the overall prevalence of S. intercalatum infection among schoolchildren was 2.4% (6/252) and girls had insignificantly higher prevalence (3.1%, 4/131) than that (1.7%, 2/121) in boys (χ2 = 0.5, P = 0.5).Conclusion
Water control and sanitation as well as snails eliminated by molluscicides are urgently needed to reduce S. intercalatum infection in DRSTP inhabitants. 相似文献74.

Vertebral compression fractures: distinction between benign and malignant causes with MR imaging 总被引:26,自引:0,他引:26
Magnetic resonance (MR) imaging was performed on 64 patients with 109 vertebral compression fractures, the cause of which could not be determined from plain radiographs. Twenty-five fractures were due to malignancy; 84 were caused by a benign process. In 22 of the 25 fractures caused by malignancy, MR images showed complete replacement of normal bone marrow, whereas 47 of the 61 benign fractures without history of trauma had complete preservation of normal bone marrow. The remaining 14 benign fractures had incompletely preserved bone marrow in a regular pattern. In two of the three remaining malignant fractures, the bone marrow replacement also was incomplete but with an irregular pattern. In cases of recent trauma or primary bone marrow abnormalities, the configuration and signal of remaining bone marrow were not useful in differentiating among malignancy, osteoporosis, and other benign processes. When criteria based on complete loss or preservation of marrow and marrow configuration in cases of incomplete loss were used, the accuracy in differentiating benign from malignant fractures was 94%. MR imaging may be a useful adjunct in differentiating benign from metastatic fractures and may provide information not available with other imaging methods. 相似文献

Five patients with chronic traumatic diaphragmatic hernia presented with symptoms of acute intestinal obstruction and unilateral pleural effusion. In each case, infarcted herniated abdominal structures were found at surgery. The presence of an ipsilateral pleural effusion is an important radiographic sign, which may indicate strangulation in patients with chronic traumatic diaphragmatic hernia. 相似文献

Paraspinal lipomatosis: a benign mass 总被引:1,自引:0,他引:1
Paraspinal lipomatosis usually occurs in patients with steroid excess. In two patients a paraspinal mass was detected on conventional radiographs and was subsequently shown to represent benign fat deposition on computed tomography, thereby obviating further studies. Neither patient had been receiving steroids. Paraspinal lipomatosis may be the cause of a benign mass and may be considered in the differential diagnosis of this finding. 相似文献

The ADA guidelines on oral malodor products 总被引:1,自引:1,他引:0
WT Wozniak 《Oral diseases》2005,11(S1):7-9
For over 130 years the ADA has been an important information source on the safety and effectiveness of dental products. The Council has recently completed the development of Acceptance Program Guidelines for products used in the management of oral malodor. The ADA Seal Program will ensure that professional and consumer dental products meet rigorous ADA criteria for safety and effectiveness 相似文献

Effect of contrast material dose on clinically evident change in renal function was studied prospectively in 200 examinations requiring intravenous or intraarterial administration of contrast material. All patients were adequately hydrated. Blood urea nitrogen and serum creatinine were measured before and after the procedure. Ionic and nonionic contrast agents were used. Total dose of contrast material ranged from 30 to 530 mL (mean, 237 mL). There was no tendency to give smaller doses to patients with preexisting renal impairment and no relationship between total dose and patient age. No consistent clinical effect on renal function was demonstrated with increasing dose, regardless of whether ionic or nonionic agents were used. In adequately hydrated low-risk patients with predominantly normal initial renal function and within the dose range studied, there does not appear to be any consistent clinical change in renal function with increasing contrast material dose. 相似文献
