By injecting small amounts of CO2 through a needle, one can move bowel or bladder from the intended path of instruments during interventional procedures. The technique worked well in six of seven cases in the pelvis and retroperitoneum; it was not effective in the mediastinum or midabdomen (n = 6). 相似文献

外科医生和手术室人员经常接触手术设备产生的烟气,病人也会暴露于烟气中,特别是腹腔镜手术中产生的烟气滞留于腹腔内这一密闭空间并被吸收.这些烟气是一种与香烟烟气相似的毒性物质,然而对这种毒性物质的影响还未引起足够重视.应该采取必要措施尽可能减少手术中烟气的不良影响. 相似文献

The expansion of women in the military is reshaping the veteran population, with women now constituting the fastest growing segment of eligible VA health care users. In recognition of the changing demographics and special health care needs of women, the VA Office of Research & Development recently sponsored the first national VA Women’s Health Research Agenda-setting conference to map research priorities to the needs of women veterans and position VA as a national leader in Women’s Health Research. This paper summarizes the process and outcomes of this effort, outlining VA’s research priorities for biomedical, clinical, rehabilitation, and health services research. 相似文献

Calciphylaxis – a topical overview 总被引:3,自引:0,他引:3
G Arseculeratne† AT Evans‡ SM Morley† 《Journal of the European Academy of Dermatology and Venereology》2006,20(5):493-502
'Calciphylaxis', a calcification syndrome associated with ischaemic cutaneous necrosis, is acquired naturally in humans in disease states. It is a life and limb-threatening complication, usually observed in patients with renal disease and secondary hyperparathyroidism, but known to occur in the absence of renal or parathyroid disease. The reported mortality rate, which ranges from 60-80%, relates to wound infection, sepsis and organ failure. It is a small-vessel vasculopathy, which is estimated to occur in about 4% of haemodialysis patients. Clinically, violaceous, reticulate areas of cutaneous necrosis and eschar may be evident, particularly in the extremities. In addition to the clinical picture, a raised calcium phosphorous product, an elevated parathyroid hormone level, radiographic evidence of vessel and soft-tissue calcification and the finding of mural calcification affecting small arteries and arterioles on histopathology help to confirm the diagnosis of this entity which generally has a poor prognosis. A high index of suspicion and an active multidisciplinary management approach, with rigorous attention to wound care and prevention of sepsis, are vital in the management of these patients. In this overview, we discuss the pathophysiology, clinical features and associations, risk factors, diagnosis and management issues relating to calciphylaxis. 相似文献

Five immunofluorescence (IF) kits or reagents (Bartels [Bartels Immunodiagnostic Supplies, Inc., Bellevue, Wash.], Imagen [CellTech Diagnostics, Ltd., distributed by Analytab Products, Plainview, N.Y.], Ortho [Ortho Diagnostics Systems, Inc., Raritan, N.J.], Syva [Syva Co., Palo Alto, Calif.], Whittaker [Whittaker Bioproducts, Walkersville, Md.]) were evaluated for typing and laboratory confirmation of herpes simplex virus (HSV). Of 101 clinical isolates tested by each kit or reagent, results for 97 of them were in agreement. Identification of the four isolates with discordant results was performed by restriction endonuclease analysis of the viral DNA. The sensitivity and specificity of the Imagen and Bartels kits were 100%. For the Ortho, Syva, and Whittaker kits or reagents, the HSV type 1 (HSV-1) and HSV type 2 (HSV-2) sensitivities were 97.4 and 100%, 100 and 100%, and 97.4 and 100%, respectively, and the specificities were 100 and 97.4%, 100 and 92.4%, and 100 and 97.4%, respectively. There was one false-positive HSV-2 isolate identified by each of the Ortho and Whittaker kits or reagents. Three false-positive HSV-2 isolates occurred by staining with Syva, giving the erroneous indication of dual isolates. Several isolates stained with Imagen and Whittaker reagents displayed dull IF patterns. A dull green background occurred in ca. one-third of the HSV-2 isolates tested with the Ortho kit. The intensities of IF staining by the Bartels and Syva kits were satisfactory; however, the latter displayed a specificity of 92.7%. A total of 38 and 63 specimens were finally designated as HSV-1 and HSV-2, respectively. Identification of each isolate with the Bartels kit was consistently interpretable and is recommended as the typing and confirmatory assay of choice. 相似文献
