Beneficial Treatment (beneficial + treatment)
Selected AbstractsGrading quality of evidence and strength of recommendations in clinical practice guidelines: Part 2 of 3.ALLERGY, Issue 8 2009The GRADE approach to grading quality of evidence about diagnostic tests, strategies The GRADE approach to grading the quality of evidence and strength of recommendations provides a comprehensive and transparent approach for developing clinical recommendations about using diagnostic tests or diagnostic strategies. Although grading the quality of evidence and strength of recommendations about using tests shares the logic of grading recommendations for treatment, it presents unique challenges. Guideline panels and clinicians should be alert to these special challenges when using the evidence about the accuracy of tests as the basis for clinical decisions. In the GRADE system, valid diagnostic accuracy studies can provide high quality evidence of test accuracy. However, such studies often provide only low quality evidence for the development of recommendations about diagnostic testing, as test accuracy is a surrogate for patient-important outcomes at best. Inferring from data on accuracy that using a test improves outcomes that are important to patients requires availability of an effective treatment, improved patients' wellbeing through prognostic information, or , by excluding an ominous diagnosis , reduction of anxiety and the opportunity for earlier search for an alternative diagnosis for which beneficial treatment can be available. Assessing the directness of evidence supporting the use of a diagnostic test requires judgments about the relationship between test results and patient-important consequences. Well-designed and conducted studies of allergy tests in parallel with efforts to evaluate allergy treatments critically will encourage improved guideline development for allergic diseases. [source] MULTIDISCIPLINARY PAIN ABSTRACTS: 39PAIN PRACTICE, Issue 1 2004Article first published online: 15 MAR 200 A literature review was conducted to review the anatomy, pathophysiology, diagnosis, procedure, and clinical results of intradiscal electrothermal therapy (IDET). Low back pain is a major physical and socioeconomic entity. A significant percentage of low back pain is attributable to internal disc disruption. The management of internal disc disruption has traditionally been limited to either conservative treatment or spinal fusion. IDET has been performed as an alternative to these therapies. The available literature was reviewed. Scientific data regarding the pathophysiology, biologic effects, and clinical results are relatively scarce. Early biomechanical and histologic investigations into the effects of IDET are conflicting. However, in early prospective human trials, IDET seems to provide some benefit with little risk. It was concluded that IDET is a potentially beneficial treatment for internal disc disruption in carefully selected patients as an alternative to spinal fusion. More basic science and clinical research with long-term follow-up evaluation is necessary. [source] Evaluation of Adrenal Suppression of a Lipid Enhanced, Topical Emollient Cream Formulation of Hydrocortisone Butyrate 0.1% in Treating Children with Atopic DermatitisPEDIATRIC DERMATOLOGY, Issue 1 2007Lawrence Eichenfield M.D. In the pediatric population however, the potential impact of adrenal suppression is always an important safety concern. Twenty boys and girls, 5,12 years of age, with normal adrenal function and a history of atopic dermatitis were maximally treated three times daily with a lipid-rich, moisturizing formulation of hydrocortisone butyrate 0.1% for up to 4 weeks. At the conclusion of the 4-week treatment period, cosyntropin injection stimulation testing showed no evidence of adrenal suppression. In addition, the therapy was noted to be highly efficacious, with a clinical success rate of 80% (Physician Global Score of (0) clear or (1) almost clear). No local side effects associated with prolonged use of topical corticosteroids were reported. In summary, this study supports the contention that this lipid-rich, moisturizing formulation of hydrocortisone butyrate 0.1% was a well-tolerated and beneficial treatment for atopic dermatitis, demonstrating no adrenal suppression in the pediatric population aged 5,12 years. The relevance of these findings for children below 5 years of age, because of difference in body mass/surface area ratios, remains to be determined. [source] Intradiscal Electrothermal Coagulation and Percutaneous Neuromodulation Therapy in the Treatment of Discogenic Low Back PainPAIN PRACTICE, Issue 3 2005Dima Rozen MD Abstract: Low back pain (LBP) is a major physical and socioeconomic entity. A significant percentage of LBP is attributable to internal disc disruption. The management of internal disc disruption has traditionally been limited to either conservative treatment or spinal fusion. Intradiscal electrothermal coagulation (IDET) and percutaneous neuromodulation therapy (PNT) are now being performed as an alternative to these therapies. Scientific data regarding the pathophysiology, biologic effects, and clinical results are relatively scarce. Early biomechanical and histologic investigations into the effects of IDET are conflicting. However, in early prospective human trials, IDET seems to provide some benefit with little risk. PNT represents a new less invasive technique for the treatment of discogenic pain, but limited research is available to determine long-term clinical efficacy. IDET and PNT are potentially beneficial treatments for internal disc disruption in carefully selected patients as an alternative to spinal fusion. More basic science and clinical research with long-term follow-up evaluation is necessary. [source] Cancer stem cells and chemoradiation resistanceCANCER SCIENCE, Issue 10 2008Hideshi Ishii Cancer is a disease of genetic and epigenetic alterations, which are emphasized as the central mechanisms of tumor progression in the multistepwise model. Discovery of rare subpopulations of cancer stem cells (CSCs) has created a new focus in cancer research. The heterogeneity of tumors can be explained with the help of CSCs supported by antiapoptotic signaling. CSCs mimic normal adult stem cells by demonstrating resistance to toxic injuries and chemoradiation therapy. Moreover, they might be responsible for tumor relapse following apparent beneficial treatments. Compared with hematopoietic malignancies, conventional therapy regimes in solid tumors have improved the overall survival marginally, illustrating the profound impact of treatment resistance. This implies that the present therapies, which follow total elimination of rapidly dividing and differentiated tumor cells, need to be modified to target CSCs that repopulate the tumor. In this review article, we report on recent findings regarding the involvement of CSCs in chemoradiation resistance and provide new insights into their therapeutic implications in cancer.
