9 [FSD] vs 3.7 [time-resolved technique] and 3.1 [high-spatial-resolution technique]) and patient (mean score, 4.0 [FSD] vs 4.2 [time-resolved technique] and 4.3 [high-spatial-resolution technique]) groups. In the control subjects, FSD angiography
depicted proper digital selleck chemical artery stenosis that was less severe (mean grade, 0.7) than that seen with the time-resolved (mean grade, 1.6) and high-spatial-resolution (mean grade, 1.0) techniques. In the patient group, FSD angiography depicted lower degrees of stenosis, with a lower mean grade for all segments combined (1.3) compared with the corresponding mean grades for time-resolved (1.5) and high-spatial-resolution (1.8) MR angiography.
Conclusion: Preliminary data indicate that the proposed nonenhanced FSD MR angiographic technique is an improvement over existing contrast-enhanced techniques for evaluation of the hand vasculature in vasospastic disorders of the selleck screening library hand. Further technical improvements and a systematic clinical study are warranted. (C) RSNA, 2011″
“Background: The leydigioma is the most frequent interstitial neoplasm of the testis. Clinical symptoms of all leydigioma usually are isosexual precocious pseudo-puberty due to autonomous testosterone overproduction, suppressed gonadotropin levels and a testis mass. Nowadays its therapy is debated.
Design and methods: We report a case
of a young child treated in 2008 for a leydigioma of the testis with GW786034 supplier atypical clinical behavior. Testicular oncologic markers and hormonal profile were assessed.
Results: The patient was treated successfully with organ-confined surgery.
Conclusion: We want to confirm the safety of conservative surgery against radical orchiectomy and review the literature of the last decade on this debated matter.”
“Toxigenic strains of Vibrio cholerae belonging to the 01 and 0139 serogroups cause cholera, a severe diarrhoeal disease that occurs frequently as epidemics in many
developing countries. Although V. cholerae is known to be a human pathogen, the bacteria constitute part of the normal aquatic flora in the ecosystem, which includes both epidemic and non epidemic strains that vary in their virulence gene profile. V. cholerae 01 and 0139 strains are commonly known to carry a set of virulence genes necessary for pathogenesis in human. The major virulence factors of V. cholerae include cholera toxin (CT), which is responsible for the profuse watery diarrhoea and a pilus colonization factor known as toxin coregulated pilus (TCP). The presence of virulence-associated genes in the environmental strains provides interesting possibility to understand the pathogenicity of the disease. The emergence of toxigenic V. cholerae strains has provided an opportunity to study the coevolution of different serogroups of epidemic V.
