Clinical Detection (clinical + detection)
Selected AbstractsRemote metastatic cervical carcinoma to kidneys mimicking bilateral renal abscessesEUROPEAN JOURNAL OF CANCER CARE, Issue 6 2007C.-M. LIN A 53-year-old woman presented bilateral renal masses, which were interpreted as abscesses with a computed tomography scan 9 years after primary surgery for cervical carcinoma. Subsequent biopsies under ultrasound guidance revealed metastatic adenocarcinoma of kidneys originating from the cervical carcinoma. Clinical detection of renal involvement from cervical cancer is extremely rare. There were only seven cases reported in the literature, and three cases were interpreted as abscesses initially. In comparison with these cases, the time between renal metastases and initial detection of cervical carcinoma is the longest in our case. [source] Clinical detection of caries in the primary dentition with and without bitewing radiographyAUSTRALIAN DENTAL JOURNAL, Issue 1 2009B Newman Abstract Background:, Inadequate detection of caries in the primary dentition due to non-use of bitewing radiography is commonly encountered in paediatric practice. The present study investigated the increased benefits of using bitewing radiography in addition to the visual-tactile examination technique for detection of primary dentition caries in a non-fluoridated community, and determined the prevalence of "hidden" occlusal caries in the primary dentition. Methods:, Primary teeth were scored for caries at the restorative threshold using a visual-tactile technique followed by bitewing radiographic examination in a sample of 611 schoolchildren aged 6.4 ± 0.5 yrs to 12.1 ± 0.8 yrs residing in a non-fluoridated city. Results:, Overall, at the restorative threshold, the visual-tactile technique could detect 62 per cent of occlusal caries compared to 74 per cent for bitewing radiography (p < 0.001). The prevalence of "hidden" occlusal caries was 12 per cent. In contrast, for primary molar proximal surface caries, the visual-tactile technique could detect only 43 per cent of caries compared with 91 per cent for bitewing radiography (p < 0.001). Conclusions:, In the primary dentition, use of bitewing radiography increases the detection rate of proximal surface caries substantially. It is recommended that bitewing radiography be included as part of the routine examination of children with proximal surfaces that cannot be visualized. [source] Resistance to thienopyridines: Clinical detection of coronary stent thrombosis by monitoring of vasodilator-stimulated phosphoprotein phosphorylationCATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 3 2003Paul Barragan MD Abstract We carried out a prospective evaluation of a new vasodilator-stimulated phosphoprotein (VASP) phosphorylation assay in order to detect patients with high-risk coronary subacute stent thrombosis (SAT) despite thienopyridine regimen. Twenty healthy donors (group 1) without any medication were compared to 16 stented patients (group 2) treated by ticlopidin or clopidogrel initiated 2 days before stenting and aspirin (250 mg/day). No difference in platelet reactivity was noted between group 1 and group 2 treated only with aspirin (72.00% ± 4.17% vs. 69.73% ± 5.62%, respectively; P = NS). Significant differences were found between patients of group 2 treated with aspirin alone (69.73% ± 5.62%), after 2.0 days (60.14% ± 9.60%; P < 0.05), and after 4.8 ± 1.3 days (48.37% ± 11.19%; P < 0.05) with thienopyridine-aspirin. Among 1,684 consecutive stented patients, 16 patients who presented an SAT (group 3) were compared with 30 other stented patients free of SAT (group 4). We found a significant difference between group 3 (63.28% ± 9.56%) and group 4 (39.80% ± 10.9%; P < 0.0001). VASP phosphorylation analysis may be useful for the detection of coronary SAT.

[source] Symposium on the musculoskeletal aspects of marfan syndrome: Meeting report and state of the scienceJOURNAL OF ORTHOPAEDIC RESEARCH, Issue 3 2007Kevin B. Jones Abstract The National Marfan Foundation sponsored a symposium in August 2005 to review recent progress in the area of Marfan-related musculoskeletal research. Orthopaedic surgeons, molecular geneticists, medical geneticists, and pain specialists met to review a variety of topics. This report reviews and summarizes the proceedings of the symposium, with emphasis on future directions for study that were identified in the course of the meeting. Areas covered include clinical detection, diagnosis, growth, spine deformity, molecular mechanisms, dural ectasia, protrusio acetabuli, and pain in Marfan syndrome. © 2006 Orthopaedic Research Society.

J Orthop Res 2007 [source] A New 4.0-Generation Dendrimer Phosphorescence Labeling Reagent and Its Application to Determination of Trace Alkaline Phosphatase by Affinity Adsorption Solid Substrate-room Temperature PhosphorimetryCHINESE JOURNAL OF CHEMISTRY, Issue 10 2007Zhi-Ming LI Abstract A Triton X-100-4.0G-D (4.0G-D refers to a 4.0-generation dendrimer) was brought forward as a new phosphorescence labeling reagent. Two types of specific affinity adsorption (AA) reactions (direct method and sandwich method) were carried out between the labeling product of Triton X-100-4.0G-D-Wheat germ agglutinin (WGA) and alkaline phosphatase (ALP), the product of AA reaction preserved the good characteristics of room temperature phosphorescence (RTP) of 4.0G-D and ,IP of the product was proportional to the content of ALP. According to the fact stated above, a new method for the determination of trace ALP by affinity adsorption solid substrate-room temperature phosphorimetry (AA-SS-RTP) was established on the basis of WGA labeled with the Triton X-100-4.0G-D. The detection limits were 0.20 ag·spot,1 (corresponding concentration: 5.0×10,16 g·mL,1, namely 5.0×10,18 mol·L,1) for a direct method and 0.14 ag·spot,1 (corresponding concentration: 3.5×10,16 g·mL,1, namely 3.5×10,18 mol·L,1) for a sandwich method, respectively. For their high sensitivity, good repeatability and high accuracy, the direct method and sandwich method have been successfully applied to determine the content of ALP in human serum, and the results were coincided with the clinical detection results of the enzyme-linked immunosorbent assay method by the Zhangzhou Hospital of Traditional Chinese Medicine. Meanwhile, the mechanism for the determination of trace ALP by AA-SS-RTP was discussed. [source] Associations of serum EBV DNA and gammopathy with post-transplant lymphoproliferative diseaseCLINICAL TRANSPLANTATION, Issue 1 2009Anne Rosselet Abstract:, Background:, Post-transplant lymphoproliferative disease (PTLD) is a life-threatening complication of immunosuppression following transplantation. Epstein,Barr virus (EBV) and gammopathy in serum are associated with PTLD, but these two parameters have not been evaluated in parallel for their association with PTLD. Methods:, We evaluated the incidence of EBV load positivity, gammopathy, and protein expression in sera from all PTLD patients diagnosed at our hospital during the past seven yr. Results were compared with those of a control group including matched transplanted patients who did not develop PTLD. Results:, Seven of 10 PTLD patients presented EBV+ PTLD, for which five patients had detectable serum EBV DNA levels compared with none of 38 controls (RR between two groups =121, p < 0.0001). Five out of 10 patients had gammopathy at PTLD diagnosis compared with 5/38 controls (RR between two groups = 6.6, p = 0.022). Additionally, protein serum analysis by high-resolution two-dimensional gel electrophoresis and image examination failed to evidence specific abnormality in patients with PTLD compared with controls. Conclusions:, Our results confirm an association between EBV in sera and gammopathy with PTLD, and highlight the high specificity of the former analysis. Whether a combination of both analyses will improve the clinical detection of PTLD remains to be evaluated in a larger prospective cohort study. [source] | ||||||||||
