Since the beginning of RHD genotyping in maternal plasma, no Rh D positive baby was diagnosed RHD negative in our institution. Genotyping from circulating DNA in maternal plasma is as efficient as genotyping on amniocyts but without the associated risks. We propose a prophylactic injection based on fetal genotyping RHD in maternal blood with 300 microg anti-D immunoglobulin at 28 weeks of amenhorrea in all of Rh D negative pregnant women whitch fetuses positive RHD.

Aim of the study : To evaluate the role of perioperative, catheter-guided fibrinolysis in the management of thrombosed popliteal artery aneurysms. Material : From 1990 to 2005, six patients suffering subacute limb ischemia, secondary to thrombosis of a popliteal artery aneurysm, benefited selective intra-arterial fibrinolysis, followed by subsequent aneurysm exclusion and bypass grafting. This represents ten percent of all popliteal aneurysms operated on in that time period and 28% of all thrombosed popliteal artery aneurysms. Results : The lytic procedure was successful in all cases, restituting patency in two (n = 3), one (n = 2) or all (n = 1) crural arteries. The venous bypass graft remained patent in all but one patient. In one patient, the graft occluded at 10 months without limb loss. This outcome compares more favorable than the result obtained with emergent surgery alone for thrombosed popliteal artery aneurysms with profound limb ischemia (eight patients, of whom one required amputation at day 5 and one lost his limb at nine months following graft thrombosis). Conclusion : Preoperative intra-arterial lytic therapy, in the setting of subacute limb ischemia caused by thrombosis of a popliteal artery aneurysm, can be considered as safe and effective.

We isolated 59 strains of cyanobacteria from the benthic microbial mats of 23 Antarctic lakes, from five locations in two regions, in order to characterize their morphological and genotypic diversity. On the basis of their morphology, the cyanobacteria were assigned to 12 species that included four Antarctic endemic taxa. Sequences of the ribosomal RNA gene were determined for 56 strains. In general, the strains closely related at the 16S rRNA gene level belonged to the same morphospecies. Nevertheless, divergences were observed concerning the diversity in terms of species richness, novelty, and geographical distribution. For the 56 strains, 21 operational taxonomic units (OTUs, defined as groups of partial 16S rRNA gene sequences with more than 97.5% similarity) were found, including nine novel and three exclusively Antarctic OTUs. Sequences of Petalonema cf. involvens and Chondrocystis sp. were determined for the first time. The internally transcribed spacer (ITS) between the 16S and the 23S rRNA genes was sequenced for 33 strains, and similar groupings were observed with the 16S rRNA gene and the ITS, even when the strains were derived from different lakes and regions. In addition, 48 strains were screened for antimicrobial and cytotoxic activities, and 17 strains were bioactive against the gram-positive Staphylococcus aureus, or the fungi Aspergillus fumigatus and Cryptococcus neoformans. The bioactivities were not in coincidence with the phylogenetic relationships, but rather were specific to certain strains. [less ▲]

This deliverable summarises all the hydrogeological experiments performed in the scope of the AquaTerra project by HGULg in the Flémalle test site. These experiments consisted in various hydraulic tests and tracer tests performed to quantify hydrodynamic and hydrodispersive properties of the alluvial gravel aquifer and to evaluate groundwater fluxes in the aquifer and at the aquifer-river interface. First steps in groundwater modelling are also presented. [less ▲]

The authors discuss the potential influence of obesity surgery on the risk of cancer, focusing on the upper GI tract directly affected by operations. There is currently no substantiation for an increased risk of cancer after bariatric surgery, because there are only about 25 reports of subsequent cancer of the esophagus and the stomach. However, this review emphasizes the need to detect potential precancerous conditions before surgery. Candidates for postoperative endoscopic surveillance may include patients >15 years after gastric surgery, but also patients symptomatic for gastroesophageal reflux disease in whom a high incidence of Barrett's metaplasia has been reported. The greatest concern is a delay in diagnosis from inadequate investigation due to mistaking serious upper GI symptoms as a consequence of the past operation. [less ▲]

Numerous studies suggest a cognitive bias for threat-related material in delusional ideation. However, few studies have examined this bias using a memory task. We investigated the influence of delusion-proneness on identity and expression memory for angry and happy faces. Participants high and low in delusion-proneness were presented with happy and angry faces and were later asked to recognise the same faces displaying a neutral expression. They also had to remember what the initial expressions of the faces had been. Remember/know/guess judgments were asked for both identity and expression memory. Results showed that delusion-prone participants better recognised the identity of angry faces compared to non-delusional participants. Also, this difference between the two groups was mainly due to a greater number of remember responses in delusion-prone participants. These findings extend previous studies by showing that delusions are associated with a memory bias for threat-related stimuli. [less ▲]

Context. Since the discovery, with the EINSTEIN satellite, of strong X-ray emission associated with HD 93162 (equivalent to WR 25), this object has been predicted to be a colliding-wind binary system. However, radial-velocity variations that would prove the suspected binary nature have yet to be found. Aims. We spectroscopically monitored this object to investigate its possible variability to address this discordance. Methods. We compiled the largest available radial-velocity data set for this star to look for variations that might be due to binary motion. We derived radial velocities from spectroscopic data acquired mainly between 1994 and 2006, and searched these radial velocities for periodicities using different numerical methods. Results. For the first time, periodic radial-velocity variations are detected. Our analysis definitively shows that the Wolf-Rayet star WR 25 is an eccentric binary system with a probable period of about 208 days. [less ▲]

We intend to analyse retrospectively whether the time interval ("gap duration" = GD) between preoperative radiotherapy and surgery in locally advanced rectal cancer (LARC) has an impact on overall survival (OS), cancer specific survival (CSS), disease free survival (DFS) and local control (LC). Two hundred seventy nine patients with LARC were entered in Trial 93-01 (hyperfractionated accelerated radiotherapy 41.6 Gy/26 Fx BID) shortly followed by surgery. From these 250 patients are fully assessable. The median GD of 5 days was used as a discriminator. The median follow-up for all patients was 39 months. GD > 5 days was a significant discriminator for actuarial 5-years OS (69% vs 47%, p = 0.002), CSS (82% vs 57%, p = 0.0007), DFS (62% vs 41%, p = 0.0003) but not for LC (93% vs 90%, p = non-significant). In multivariate analysis, the following factors independently predict outcome; for OS: age, GD, circumferential margin (CM) and nodal stage (ypN); for CSS: GD, ypN and vascular invasion (VI); for DFS: CEA, distance to anal verge, GD, ypN and VI; for LC: CM only. Gap duration predicts survival outcome but not local control. The patients submitted to surgery after a median delay of more than 5 days had a significantly better outcome. [less ▲]

Purpose of review We discuss the problems of evidence-based neurorehabilitation in disorders of consciousness, and recent functional neuroimaging data obtained in the vegetative state and minimally conscious state. Recent findings Published data are insufficient to make recommendations for or against any of the neurorehabilitative treatments in vegetative state and minimally conscious state patients. Electrophysiological and functional imaging studies have been shown to be useful in measuring residual brain function in noncommunicative brain-damaged patients. Despite the fact that such studies could in principle allow an objective quantification of the putative cerebral effect of rehabilitative treatment in the vegetative state and minimally conscious state, they have so far not been used in this context. Summary Without controlled studies and careful patient selection criteria it will not be possible to evaluate the potential of therapeutic interventions in disorders of consciousness. There also is a need to elucidate the neurophysiological effects of such treatments. Integration of multimodal neuroimaging techniques should eventually improve our ability to disentangle differences in outcome on the basis of underlying mechanisms and better guide our therapeutic options in the challenging patient populations encountered following severe acute brain damage.
