The situation of end-stage renal disease (ESRD) patients in central and eastern Europe was very poor for many years during the so called socialistic era. Economical and political liberation resulted in the significant growth of renal replacement facilities in this region. The number of hemodialysis units increased significantly (56%) during the period 1990–1996, and the number of patients treated with this modality has risen by 75%. More dramatic progress was achieved in peritoneal dialysis. The number of units performing this method of renal replacement therapy (RTT) increased by 277% and the number of patients by more than 300%. Not only quantitative but also qualitative changes were observed. More modern hemodialysis machines installed in the vast majority of units allow for the performance of bicarbonate dialysis, controlled ultrafiltration, and sodium profile modeling. Also, a wider choice of biocompatible dialyzers has become available during the last few years. The number of centers performing renal transplantation has increased significantly, but the number of renal transplants has not followed this progress. Despite all the progress, further development of all RRT methods is necessary to achieve acceptance rates comparable to those observed in developed countries. 相似文献

Videocapsule endoscopy (VCE) can identify lesions in the small bowel which would otherwise be hard to detect. We have selected 53 patients with digestive symptoms in which upper and lower endoscopy had provided no findings. Patients were classified into three groups, based on their main indication for VCE exploration: group one--obscure gastrointestinal bleeding (OGIB); group two--unspecific abdominal symptoms; group 3--monitoring of a prior known pathology. We found that VCE has high predictive values, sensibility and specificity in the diagnosis of OGIB. VCE was also useful in the detection and extent evaluation of lesions in Crohn's and celiac disease. VCE is also able to detect tumors of the small bowel with sufficient accuracy, and can be used to monitor patients with hereditary pre-malignant diseases such as FAP. There were few light adverse effects and no major complications. We conclude that VCE is a safe and effective procedure for the detection of small bowel lesions. 相似文献

Purpose of the study: The conditions of renal
replacement therapy (RRT) were very poor in the countries located in
Central and Eastern Europe (CEE) when they were members of the so-called
'socialist bloc'. The aim of the present analysis was to document the
impact of the socioeconomic changes on dialysis therapy in the CEE
countries. Design: This was a special survey with the
participation of 12 CEE countries, with data obtained through national
registries (with the exception of Russia). Results:
during the period 1990-1996 the number of haemodialysis units increased by
56% and the number of centres performing peritoneal dialysis by 296%. The
number of patients increased respectively by 78% (haemodialysis) and 306%
(peritoneal dialysis). The percentage of patients with diabetic nephropathy
and elderly patients rose dramatically during this period. One of the main
reasons of such expansion was the rapid development of peritoneal dialysis
programmes in the majority of the CEE countries. The introduction of modern
haemodialysis machines and a wider choice of different dialysers and
concentrates permitted individualization of dialysis procedures. These
points and the wider use of erythropoietin had a positive influence on
quality of life and treatment outcome. There was also a notable increase in
the number of transplant centres, but less so of the number of transplanted
patients. Conclusion: Renal replacement therapy
experienced a major expansion in the CEE countries. Despite progress
achieved, the level of RRT is not yet completely satisfactory in most CEE
countries. 相似文献

AIM: To evaluate neoangiogenesis in patients with colon cancer by two fluorescently labeled antibodies on fresh biopsy samples imaged with confocal laser endomicroscopy (CLE).METHODS: CLE is an imaging technique for gastrointestinal endoscopy providing in vivo microscopy at subcellular resolution. An important question in validating tumor angiogenesis is what proportion of the tumor vascular network is represented by pre-existing parent tissue vessels and newly formed vessels. CD105 (endoglin) represents a proliferation-associated endothelial cell adhesion molecule. In contrast to pan-endothelial markers, such as CD31, CD105 is preferentially expressed in activated endothelial cells that participate in neovascularization. Thus, we evaluated CD105 and CD31 expression from samples of ten patients with primary rectal adenocarcinoma, using a dedicated endomicroscopy system. A imaging software was used to obtain the Z projection of the confocal serial images from each biopsy sample previously combined into stacks. Vascular density and vessel diameters were measured within two 50 μm x 475 μm rectangular regions of interest centered in the middle of each image in the horizontal and vertical direction. The results were averaged over all the patients and were expressed as the mean ± SE.RESULTS: The use of an anti-CD105 antibody was found to be suitable for the detection of blood vessels in colon cancer. Whereas anti-CD31 antibodies stained blood vessels in both normal and pathologic colon equally, CD105 expression was observed primarily in malignant lesions, with little or no expression in the vessels of the normal mucosa (244.21 ± 130.7 vessels/mm3 in only four patients). The average diameter of anti-CD105 stained vessels was 10.97 ± 0.6 μm in tumor tissue, and the vessel density was 2787.40 ± 134.8 vessels/mm3. When using the anti-CD31 antibody, the average diameter of vessels in the normal colon tissue was 7.67 ± 0.5 μm and the vessel density was 3191.60 ± 387.8 vessels/mm3, while in the tumors we obtained an average diameter of 10.88 ± 0.8 μm and a vessel density of 4707.30 ± 448.85 vessels/mm3. Thus, there were more vessels stained with CD31 than CD105 (P < 0.05). The average vessel diameter was similar for both CD31 and CD105 staining. A qualitative comparison between CLE vs immunohistochemistry lead to similar results.CONCLUSION: Specific imaging and quantification of tumor microvessels are feasible in human rectal cancer using CLE examination and CD105 immunostaining of fresh tissue samples. 相似文献

Despite significant advances in imaging techniques, the incidence of colorectal cancer has been increasing in recent years, with many cases still being diagnosed in advanced stages. Early detection and accurate staging remain the main factors that lead to a decrease in the cost and invasiveness of the curative techniques, significantly improving the outcome. However, the diagnosis of pedunculated early colorectal malignancy remains a current challenge. Data on the management of pedunculated cancer precursors, apart from data on nonpolypoid lesions, are still limited. An adequate technique for complete resection, which provides the best long-term outcome, is mandatory for curative intent. In this context, a discussion regarding the diagnosis of malignancy of pedunculated polyps, separate from non-pedunculated variants, is necessary. The purpose of this review is to provide a critical review of the most recent literature reporting the different features of malignant pedunculated colorectal polyps, including diagnosis and management strategies. 相似文献

In patients with chronic renal failure undergoing hemodialysis were recorded and studied by various authors multiple eye damage with time. Studying the literature we conducted a study to assess the impact of intradialitic-interdialitic and postdialitic volemic game above the retinal circulation. By measuring diameters of retinal circulation after processing the digital fundus, we found that, 30 minutes after hemodialysis session takes a degree of dilatation of retinal vessels, permanent vascular insult that can be responsible for stroke and ischamic eye and coronary diseases of these patients. 相似文献

The proximal esophagus is rarely examined,and its inspection is often inadequate.Optical chromoendoscopy techniques such as narrow band imaging improve the detection rate of inlet patches in the proximal esophagus,a region in which their prevalence is likely underestimated.Various studies have reported correlations between these esophageal marks with different issues such as Barrett’s esophagus,but these findings remain controversial.Conflicting reports complicate the process of interpreting the clinical features of esophageal inlet patches and underestimate their importance.Unfortunately,the limited clinical data and statistical analyses make reaching any conclusions difficult.It is hypothesized that inlet patches are correlated with various esophageal and extraesophageal symptoms,diagnoses and the personalized therapeutic management of patients with inlet patches as well as the differential diagnosis for premalignant lesions or early cancers.Due to its potential underdiagnosis,there are no consensus guidelines for the management and follow up of inlet patches.This review focuses on questions that were raised from published literature on esophageal inlet patches in adults. 相似文献
