Accurate diagnosis of predominantly colonic inflammatory bowel disease(IBD) is not possible in 30% of patients. For decades, scientists have worked to find a solution to improve diagnostic accuracy for IBD, encompassing Crohn’s colitis and ulcerative colitis. Evaluating protein patterns in surgical pathology colectomy specimens of colonic mucosal and submucosal compartments, individually, has potential for diagnostic medicine by identifying integrally independent, phenotype-specific cellular and molecular characteristics. Mass spectrometry(MS) and imaging(I) MS are analytical technologies that directly measure molecular species in clinical specimens, contributing to the in-depth understanding of biological molecules. The biometric-system complexity and functional diversity is well suited to proteomic and diagnostic studies. The direct analysis of cells and tissues by Matrix-Assisted-Laser Desorption/Ionization (MALDI) MS/IMS has relevant medical diagnostic potential. MALDI-MS/IMS detection generates molecular signatures obtained from specific cell types within tissue sections. Herein discussed is a perspective on the use of MALDI-MS/IMS and bioinformatics technologies for detection of molecular-biometric patterns and identification of differentiating proteins. I also discuss a perspective on the global challenge of transferring technologies to clinical laboratories dealing with IBD issues. The significance of serologic-immunometric advances is also discussed. 相似文献

The Japanese Dermatological Association prepared guidelines focused on the treatment of skin ulcers associated with connective tissue disease/vasculitis practical in clinical settings of dermatological care. Skin ulcers associated with connective tissue diseases or vasculitis occur on the background of a wide variety of diseases including, typically, systemic sclerosis but also systemic lupus erythematosus (SLE), dermatomyositis, rheumatoid arthritis (RA), various vasculitides and antiphospholipid antibody syndrome (APS). Therefore, in preparing the present guidelines, we considered diagnostic/therapeutic approaches appropriate for each of these disorders to be necessary and developed algorithms and clinical questions for systemic sclerosis, SLE, dermatomyositis, RA, vasculitis and APS. 相似文献

Burns are a common type of skin injury encountered at all levels of medical facilities from private clinics to core hospitals. Minor burns heal by topical treatment alone, but moderate to severe burns require systemic management, and skin grafting is often necessary also for topical treatment. Inappropriate initial treatment or delay of initial treatment may exert adverse effects on the subsequent treatment and course. Therefore, accurate evaluation of the severity and initiation of appropriate treatment are necessary. The Guidelines for the Management of Burn Injuries were issued in March 2009 from the Japanese Society for Burn Injuries as guidelines concerning burns, but they were focused on the treatment for extensive and severe burns in the acute period. Therefore, we prepared guidelines intended to support the appropriate diagnosis and initial treatment for patients with burns that are commonly encountered including minor as well as moderate and severe cases. Because of this intention of the present guidelines, there is no recommendation of individual surgical procedures. 相似文献

The Wound/Burn Guidelines Committee consists of members commissioned by the Board of Directors of the Japanese Dermatological Association (JDA). It held several meetings and evaluations in writing since October 2008, and drafted five guidelines for the diagnosis and treatment including commentaries on wounds in general and the Guidelines for the Diagnosis and Treatment for Pressure Ulcers by taking opinions of the Scientific Committee and Board of Directors of JDA into consideration. 相似文献

BACKGROUND: The aim of this study was to evaluate the necessity of 2-[fluorine-18]fluoro-2-deoxy-D-glucose-positron emission tomography/computed tomography (FDG-PET/CT) after end of treatment in lymphoma patients who had an interim FDG-PET/CT. PATIENTS AND METHODS: In 38 patients with Hodgkin's disease (HD) and 30 patients with non-Hodgkin's lymphoma (NHL) interim PET/CT (intPET) after two to four cycles of chemotherapy and PET/CT after completion of first-line treatment (endPET) were carried out. Cost reduction was retrospectively calculated for the potentially superfluous endPET examinations. RESULTS: In 31 (82%) HD patients, intPET demonstrated complete remission (CR) which was still present on endPET. The remaining seven HD patients (18%) had partial remission (PR) on intPET. For NHL, 22 (73%) patients had CR on intPET analysis which was still present on endPET. In the remaining eight NHL patients, intPET revealed PR in seven and stable disease in one patient. None of all intPET complete responders progressed until the end of therapy. Thus, of the 196 PET/CT's carried out in our study population, 53 endPET's (27.0%) were carried out in interim complete responders. CONCLUSION: End-treatment PET/CT is unnecessary if intPET shows CR and the clinical course is uncomplicated. An imaging cost reduction of 27% in our study population could have been achieved by omitting end of treatment FDG-PET/CT in interim complete responders. 相似文献

The ethanol extract from the fruit of Terminalia chebula (Combretaceae) exhibited significant inhibitory activity on oxidative stress and the age-dependent shortening of the telomeric DNA length. In the peroxidation model using t-BuOOH, the T. chebula extract showed a notable cytoprotective effect on the HEK-N/F cells with 60.5 +/- 3.8% at a concentration of 50 microg/ml. In addition, the T. chebula extract exhibited a significant cytoprotective effect against UVB-induced oxidative damage. The life-span of the HEK-N/F cells was elongated by 40% as a result of the continuous administration of 3 microg/ml of the T. chebula extract compared to that of the control. These observations were attributed to the inhibitory effect of the T. chebula extract on the age-dependent shortening of the telomere, length as shown by the Southern blots of the terminal restriction fragments (TRFs) of DNA extracted from subculture passages. 相似文献

Objective There are many predictive factors for gefitinib sensitivity, including epidermal growth factor receptor (EGFR) gene mutation, EGFR copy number, and k-ras mutation. To investigate all of them is too expensive. We evaluated the chemosensitivity for gefitinib in non-small-cell
lung cancer (NSCLC) using a histoculture drug response assay (HDRA).
Methods Surgically resected fresh tumor specimens from 22 patients with NSCLC were used. There were 13 male and 9 female patients,
ranging in age from 49 to 84 (average 70) years old. Sixteen patients (73%) were smokers. Sixteen adenocarcinomas, four squamous
cell carcinomas, and two other histological types were included. Small pieces of viable cancer tissue were placed on the collagen
gel and then cultured for 7 days in the presence of gefitinib.
Results The HDRA was successful in all specimens. A dose-response relation was observed between inhibition rates and gefitinib concentration
(p = 0.016). The inhibition rate at 20 μg/ml (IR20) in adenocarcinoma without smoking (39.2% ± 35.1%, n = 6) was higher than that with smoking (2.2% ± 5.0%, n = 10, P = 0.001) and that of nonadenocarcinoma (16.9% ± 23.6%, n = 6, P = 0.09). Gene mutation analysis was performed in two of three adenocarcinomas without smoking, which showed especially high
IR20 values, and sensitizing mutations were observed in these specimens. A cutoff inhibition rate of approximately 40%–50% appeared
to be suitable for a concentration of 20 μg/ml.
Conclusion HDRA appears to be applicable for evaluating sensitivity to gefitinib in NSCLC. It provides a convenient method for predicting
the response to gefitinib in patients with NSCLC whose fresh tumor specimens are available. 相似文献
