Objective To explore the methods of evidence-based individualized treatment for a patient with oral pemphigus. Methods According to chnical problems, we searched The Coehrane Library （Issue 1,2005 ） , MEDLINE （1966 -Jan. 2005 ）, SUMSEAR.CH （Jan. 2005 ）, TRIPDATABASE （1997 - 2005 ）, CMCC （1994 - 2004 ）and handsearched four Chinease journals （starting pubhcation -2004）. Results No Systematic review was found. Six randomised controlled trials, two reviews of high quality and one guidehne were identified. We found that corticosteroid was the firsthne medicine in the treatment of pemphigus. However, corticosteroid at higher dose did not work more effectively than that at lower dose. Corticosteroid at middle-dose was preferred in treating oral pemphigus. Additionally, corticosteroid combined with immunosuppressants led to lower mortality. Among them, cyclophosphamide and azathioprine were recommended, and methopterin should be avoided. Plasma exchange in combination with corticosteroid at lowor middle-dose should not be recommended in conventional therapy. Chinese traditional treatment combined with Western medicine might work. A treatment with prednisone at the dose of 60 mg/d and in combination with azathioprine 100mg/d was made based on the evaluation of the data available and was proved optimal by 6 months following-up. Conclusions The therapeutic effect of pemphigus has been improved by evidence-based treatment.
Objective To make an individualized therapeutic regimen for a patient with stage III relapsed ovarian cancer guided by evidence-based medicine.Methods According to the clinical problems this patient showed and the PICO (patient, intervention, comparison and outcome) principle, the best clinical evidence associated with relapsed ovarian cancer was retrieved and evaluated. Results The current evidence showed that the relapsed ovarian cancer with platinum resistance tended to be treated by pharmacotherapy. Consequently, on the basis of combining the recommended guidelines, randomized controlled trials (RCTs), systematic reviews or meta-analyses on RCTs, clinical experience from doctors and willingness of patient, the regimen of Irinotecan plus Pegylated Liposomal Doxorubicin for interventional chemotherapy was recommended for this patient. After three courses of the treatment, the disease got some relieved; the medical team would like to keep conducting the same regimen for another six to eight courses, and the follow-up visit was undergoing. Conclusion For patients with relapsed ovarian cancer with platinum resistance, an individualized therapeutic regimen under the guidance of evidence-based methods can not only improve the therapeutic efficacy but also guide both doctors and patients to take the indeterminate risk of medicine.
Objective To make an evidence-based treatment plan for a smoker with periimplantitis. Methods Based on the clinical problems raised from the case, we searched The Cochrane Library (Issue 2, 2009), ACP Journal Club (1991 to July 2009), MEDLINE (1950 to July 2009), EMbase (1980 to July 2009) and Chinese Journal Fulltext Database (1994 to July 2009) for guidelines, systematic reviews, meta-analyses and randomized controlled trials (RCTs). The quality of the included studies was assessed. Results A total of 4 systematic reviews, 8 RCTs were included. The following methods were supported by Level A evidence: (1) Scaling combined with local antibiotics; (2) Guided bone regeneration; (3) Non-surgical debridement with titanium hand-instruments or with an ultrasonic device. Based on the available evidence, we proposed a three-stage therapy plan for the patient: In the first stage, full mouth ultrasonic scaling was performed. The peri-implant pocket was debrided with plastic curettes, and then minocycline gel was applied once a week for four times. The patient was persuaded to maintain oral hygiene and quit smoking. In the second stage, four weeks later, open flap debridement and guided bone regeneration were conducted. In the third stage, long-term care of oral hygiene and dental implants were performed. After 6 months of follow-up, the peri-implant tissues were healthy with no evidence of inflammation, bleeding or suppuration. Conclusion Based on the approach of evidence-based medicine, we accomplished the treatment of the case with reliable outcomes.
Objective We searched and reviewed medical evidence to find the guide of treatment for local advanced nasopharyngeal carcinoma. Methods Firstly, we put forward clinical questions. Secondly, we searched medical evidence from Medline (1985-2002), Embase (1984-2000), Cochrane library (2002.1) and ACP. And then we reviewed the results. The key words we used were "nasopharyngeal carcinoma, chemotherapy and radiotherapy randomized" and "meta analysis or randomized control trial". Results Through searching, we got 17 papers including 1 systematic review and 16 randomized control trials, in which there were 8 prospective randomized phase Ⅲ trials. Most of these trials concluded that combination chemo-radiotherapy were better than radiotherapy alone. We think these results were suitable for our patient’treatment decision. Conclusion To treat our patients,we choosed the method of the mutimodality of squeitial neoadjuvant chemotherapy, concurrent chemo-radiotherapy and adjuvant chemotherapy with the drug doses down-adjusted.
Objective To formulate an individualized evidence-based treatment for a patient with severe obesity. Methods According to the PICO (patient intervention comparison outcome) principle, the evidence was collected and critically assessed after the clinical issues were put forwarded. The patient’s preference was also taken into account in the decision making process. Results Nine clinical guidelines, eight systematic reviews or meta-analyses and three randomized controlled trials (RCTs) were included. According to the data from the included studies and patient’s special condition, a reasonable surgical treatment regime was made to reduce the weight, relieve all kinds of complications and improve the life quality which were all regarded as the expected target. After one year’s follow-up, the patient’s weight reduced by 20 kg, and some obesity-related co-morbidities such as sleep apnea syndrome and hyperlipoidemia were also improved significantly. Conclusion The laparoscopic adjustable gastric band is an effective operation for severely obese individuals. This procedure can not only achieve weight loss, but also improve some obesity-related co-morbidities.
Objective We intended to get a good understanding of the current role of alkylating agents in the treatment of idiopathic membranous nephropathy (IMN) with nephrotic syndrome (NS). Methods We searched the Cochrane Library ( Issue 3, 2005), MEDLINE (1978 Jun., 2005) and CBM disc(1978-2005) to get the current best evidence of alkylating agents for treating IMN with NS and further critically appraised the available evidence. Results Alkylating agents showed a significant beneficial effect on complete remission of proteinuria. The treatment of glucocorticoid with cyclophosphamide (MP+CTX) was one of the best managements among the various regimens suggested for IMN, but it was not clear about its long-term effect on renal survival rate. Given the current best evidence together with our clinical experience and the attitudes of the patient and family members, the treatment of (MP+CTX) was administered. There was a significant remission of proteinuria after 6 months follow-up. Conclusions The treatment of (MP+CTX) can significantly improve the remission of proteinuria, however further observations on the long-term effect of alkylating agents on renal survival rate are required.
Lung cancer is an epithelial cancer arising from the bronchial surface epithelium or bronchial mucous glands. Non-small lung cancer constitutes about 75%-80% of all lung cancer. At the time of diagnosis, a lot of people have got stage Ⅲb non-small lung cancer which is unresectalbe. Both chemotherapy and radiotherapy are widely used in unresectable stage Ⅲ non-small lung cancer. The regimes of chemotherapy or radiotherapy are varied too. Systematic reviews and randomized controlled trials have provide much convincing evidence for us to choose and utilize the most appropriate treatment.
Objective To formulate an evidence-based treatment for a patient newly diagnosed with follicular lymphoma. Methods Based on the clinical questions we raised, evidence including systematic reviews and randomized controlled trials was collected from ACP Journal Club (1991 to November 2007), The Cochrane Library (Issue 4, 2007) and PubMed. The retrieved studies were further critically appraised. Results The addition of rituximab to chemotherapy (R-chemo) was superior to chemotherapy alone in patients with follicular lymphoma. The regimen of CVP chemotherapy plus rituximab (R-CVP) was administered to the patient. After 4 courses of R-CVP, the patient had a complete response (CR). Conclusion In newly diagnosed patients with follicular lymphoma, R-chemo is an effective treatment regimen.
Objective To apply the evidence-based treatment method to direct the clinical therapy of refractory chronic lymphocytic leukemia (CLL). Methods Such evidence-based medicine databases as The Cochrane Library (Issue 10, 2010), OVID database, PubMed (January 1992 to October 2010) and http://www.nccn.org/ were searched to find the clinical evidence with high quality and the optimum treatment was designed based on the patient’s preferences. Results Two RCTs and five CCTs were included. The available clinical evidence displayed that rituximab could improve the therapeutic effect of combined chemotherapy on the refractory CLL, the COP/CHOP regimens were effective for the fludarabine-resistant CLL, and hematopoietic stem cell transplantation could be an effective salvage therapy for the relapsed/refractory CLL, but not the first-line recommendation drug. This patient was treated by CHOP regimen combined with rituximab, the condition of disease was improved two months after stopping chemotherapy, and the follow-up was conducted. Conclusion Current evidence reveals that rituximab combined with CHOP regimen produces good tolerance with a better clinical outcome than that of CHOP regimen. Clinical practice results display that the combination of rituximab and CHOP regimen can bring good prognosis to the patient, but still needs high-quality evidence to prove．
Objective To explore the methods of evidence-based individualized treatment for a patient with Graves’ disease. Method We searched The Cochrane Library (Issue 3, 2006), SUMSEARCH (Jan.1980 to Mar. 2006), PubMed (1980 to Mar.2006), CNKI (Jan.1980 to Mar. 2006) and VIP (Jan.1980 to Mar.2006) to identify the best evidence for antithyroid drugs, iodine radioisotopes and thyroidectomy for patients with Graves’ hyperthyroidism and evaluate the quality of available evidence. Results We identified 1 clinical guideline, 1 Cochrane systematic review, 1 meta-analysis and 15 randomized controlled trials. There was no significant difference between the titration regimen and the block-replace regimen in the relapse of hyperthyroidism, while the block-replace regimen was associated with more adverse effects. Prescribing replacement thyroxine, either with or after the anti-thyroid drug treatment, had no significant effect on relapse. Methimazole was more effective than propylthiouracil in the induction of euthyroidism. There was no significant difference in the quality of life between the drugs, 131I and the thyroidectomy therapy, and the relapse was lower with thyroidectomy therapy but the cost was higher. Given the current evidence together with our clinical experience and considering the patient and her family’s values and preferences, methimazole (10 mg tid) was administered to her and then gradually reduced. No obvious adverse effects occurred within 4 months’ follow-up. Conclusion Drugs, radioactive iodine and thyroidectomy are all effective in the treatment of Graves’ hyperthyroidism. Methimazole is an effective and well tolerated drug for the treatment of Graves’ hyperthyroidism and further research into side effect are needed. Prescribing replacement thyroxine has no significant effect on relapse.
