Spinal cord ischemia is a major cause of complications after operative and endovascular treatment of descending thoracic or
thoracoabdominal aortic aneurysms. Prior revascularization of the intercostal artery (IA) giving rise to the artery of Adamkiewicz
(AA) using an artery of the thoracic wall would preserve circulation in the AA and allow obstruction of the IA at its origin.
The purpose of this study was to determine the feasibility of revascularization of the IA giving rise to the AA using three
thoracic wall arteries, i.e., lateral thoracic artery, thoracodorsal artery, and descending scapular artery. A total of 16
specimens from 8 cadavers (6 men and 2 women) were prepared. The length and diameter of the thoracic wall arteries were measured
to ascertain the feasibility of revascularization of the IA giving rise to the AA. In addition, 12 preoperative spinal cord
arteriograms were studied. We found that revascularization of the IA giving rise to the AA using thoracic wall arteries is
feasible. This technique could be used to prevent spinal cord complications after treatment of descending thoracic or thoracoabdominal
aortic aneurysms. 相似文献

Purpose
Probiotics have been shown to be able to restore a non-pathogenic digestive flora, to prevent digestive colonization by pathogenic bacteria, and to modulate immunity. The aim of this study was to assess the effects of prophylactic probiotic administration in patients ventilated for up to 2 days. 相似文献53.

Human pegivirus (HPgV, formerly GBV-C) is a member of the genus Pegivirus, family Flaviviridae. Despite its identification more than 20 years ago, both natural history and distribution of this viral group in human hosts remain under exploration. Analysis of HPgV genomes characterized up to now points out the scarcity of French pegivirus sequences in databases. To bring new data regarding HPgV genomic diversity, we investigated 16 French isolates obtained from hepatitis C virus-RNA and human immunodeficiency virus-RNA–positive blood donations following deep sequencing and coupled molecular protocols. Initial phylogenetic analysis of 5′-untranslated region (5′-UTR)/E2 partial sequences permitted to assign HPgV isolates to genotypes 2 (n = 15) and 1 (n = 1), with up to 16% genetic diversity observed for both regions considered. Seven nearly full-length representative genomes were characterized subsequently, with complete polyprotein coding sequences exhibiting up to 13% genetic diversity; closest nucleotide (nt) divergence with available HPgV sequences was in the range 7% to 11%. A 36 nts deletion located on the NS4B coding region (N-terminal part, 12 amino acids) of the genotype 1 HPgV genome characterized was identified, along with single nucleotide deletions in two genotype 2, 5′-UTR sequences. 相似文献

Isolation of Francisella tularensis by Centrifugation of Shell Vial Cell Culture from an Inoculation Eschar 总被引:1,自引:0,他引:1 下载免费PDF全文

A 52-year-old man was admitted to the hospital following the development of an inoculation eschar and fever six days after being bitten by a tick. He was clinically diagnosed as suffering from rickettsiosis. Eschar biopsy cultures on standard bacteriological media remained sterile. However, inoculation of cells with the homogenized specimen by the centrifugation-shell vial technique (M. Marrero and D. Raoult, Am. J. Trop. Med. Hyg. 40:197–199, 1989) resulted in the recovery of a bacterium. Determination of the sequence of the 16S rRNA gene amplified from the organism and comparison of the sequence to other sequences identified it as a strain of Francisella tularensis, whereas the specific serology was still negative. Our findings demonstrate that the centrifugation-cell culture, which is a tool for investigation of tick-transmitted diseases, may have the potential to serve as a method for the cultural isolation of F. tularensis. 相似文献

Prospectively collected, contemporary data are lacking on how the features of infective endocarditis (IE) vary according to region. We, therefore, compared IE in Rennes, France and Khon Kaen, Thailand. Fifty-eight patients with confirmed IE were enrolled at each site during 2011 and 2012 using a common protocol. Compared with French patients, Thais had a lower median age (47 versus 70 years old; P < 0.001) and reported more animal contact (86% versus 21%; P < 0.001). There were more zoonotic infections among Thai than France patients (6 and 1 cases; P = 0.017) and fewer staphylococcal infections (4 versus 15 cases; P = 0.011). Underlying rheumatic heart disease was more prevalent in Thai than in French patients (31% and 4%; P = 0.001), whereas prosthetic heart valves were less prevalent (9% and 35%; P = 0.001). Our data strengthen previous observations that IE in the tropics has distinctive demographic characteristics, risk factors, and etiologies and underscore the need for improved prevention and control strategies. 相似文献

After obstetrical surgery, a young woman developed an acute renal failure of one kidney, the other having been protected by a fortuitous ureteral ligation. The possible effects of a temporary kidney exclusion on itself and on the other kidney are discussed. 相似文献

A case of pulmonary oedema following acute pharyngo-laryngeal obstruction is reported. The case is compared with the results of the literature. The haemodynamic data suggested a non-cardiogenic effect, with low pulmonary arterial occlusion pressure of 1 mmHg and right-to-left shunting. Positive end-expiratory pressure was used with success. The mechanisms underlying such oedema are not well known, and may include disturbances in the balance of transpulmonary forces or hypoxia. However the outcome is usually favourable. 相似文献

rpoB gene sequence-based identification of aerobic Gram-positive cocci of the genera Streptococcus, Enterococcus, Gemella, Abiotrophia, and Granulicatella 下载免费PDF全文
We developed a new molecular tool based on rpoB gene (encoding the beta subunit of RNA polymerase) sequencing to identify streptococci. We first sequenced the complete rpoB gene for Streptococcus anginosus, S. equinus, and Abiotrophia defectiva. Sequences were aligned with these of S. pyogenes, S. agalactiae, and S. pneumoniae available in GenBank. Using an in-house analysis program (SVARAP), we identified a 740-bp variable region surrounded by conserved, 20-bp zones and, by using these conserved zones as PCR primer targets, we amplified and sequenced this variable region in an additional 30 Streptococcus, Enterococcus, Gemella, Granulicatella, and Abiotrophia species. This region exhibited 71.2 to 99.3% interspecies homology. We therefore applied our identification system by PCR amplification and sequencing to a collection of 102 streptococci and 60 bacterial isolates belonging to other genera. Amplicons were obtained in streptococci and Bacillus cereus, and sequencing allowed us to make a correct identification of streptococci. Molecular signatures were determined for the discrimination of closely related species within the S. pneumoniae-S. oralis-S. mitis group and the S. agalactiae-S. difficile group. These signatures allowed us to design a S. pneumoniae-specific PCR and sequencing primer pair. 相似文献
