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 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 give an individualized treatment to a young woman with primary dysmenorrhea. Methods According to the basic principle and methods of evidence-base medicine, we searched The Cochrane Library (Issue 1, 2009), MEDLINE (PubMed, January 1950 to May 2009), ACP Journal Club (OVID, January 1991 to May 2007) for systematic reviews and randomized controlled trials (RCTs) to acquire the best clinical evidence on the treatment of primary dysmenorrhea. Results A total of 11 systematic reviews and 1 RCT were identified. A reasonable treatment plan was made through combining the patient’s will with her family members’. Conclusion The treatment effect on primary dysmenorrhea of the young woman is improved by an individualized treatment plan based on an evidence-based method.
Objective To search evidence in the treatment of Philadelphia chromosome （Ph）-positive acute lymphocytic leukemia （ALL） for guiding chnical practice. Methods We searched MEDLINE （February, 1970～July, 2005 ） and SUMSEAILCH （till July, 2005 ）to identify systematic reviews（SIL）, randomized controlled trials（RCTs） and controlled clinical trials （CCTs） in the treatment of Ph-positive ALL. Results One RCT and 8 CCTs were identified. The results showed that Ph-positive ALL had a very poor prognosis . Chemotherapy and bone marrow transplantation （BMT） were the two main ways to treat the disease. Outcome of conventional chemotherapy treatment for adults with the disease was poor. Outcome of treatment with hyper-CVAD and imatinib mesylate was better and BMT was the only way which could potentially cure the disease. Conclusions Treatment of Ph-positive ALL with hyper-CVAD and imatinib mesylate may induce higher remission rate and disease free survival rate. BMT is the best way to cure the disease.
Objective Methods of evidence-based medicine were used to make an individualized treatment plan concerning newly diagnosed open-angle glaucoma patient. Methods After clinical problems were put forward, evidence was collected from Cochrane Library (Issue 4, 2009), PubMed (1990 -2009), MEDLINE (1990-2009), EMbase (1990-2009), CBM (1990-2009), and CNKI (1990-2009) according to the search strategy. Subject words were open-angle glaucoma, timolol, latanoprost, trabeculectomy, intraocular pressure, randomized controlled trials, human, meta-analysis, systematic review. Results A total of 221 randomized controlled trials, and 19 systematic reviews were identified. A rational treatment plan was made upon a serious evaluation of the data. After one year follow-up, the plan was proved optimal. Conclusion The treatment efficacy in newly diagnosed open-angle glaucoma has been improved by determining an individualized treatment plan according to evidence-based methods.
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.
ObjectiveTo explore an individualized treatment program to prevent the initial bleeding of a patient with cirrhosis and esophageal varices by the methods of evidence-based medicine. MethodsOne patient with cirrhosis and esophageal varices was admitted into our hospital on November 2, 2013. After evaluating the patient's condition adequately, we proposed the problem according to the PICOS principles. Then, we assessed the clinical evidence from the Cochrane Library (1990-2012), Medline (1950-2012), Embase (1991-2012), VIP (1989-2013), and CBM (1990-2013). The individualized treatment plan was made through doctors' experiences and analysis of those high-quality evidences from the databases. ResultsEight studies (randomized controlled trials and 5 meta-analysis) were included. We evaluated a series of associated problems:whether we should take measurement to prevent initial bleeding of esophageal varices; which one (β-blockers or ligation of esophageal varices) was the best method to prevent the initial bleeding based on efficacy, complication and cost-effectiveness. Then, according to the evidences and the patient's view, we gave non-selectiveβ-blocker as the primary prevention. After one-year followed-up, the initial bleeding of the patient did not occur. ConclusionMaking the prevention plan for a patient with cirrhosis and esophageal varices can not only find out the individualized program, but also push the patient to make decision for their own health.
Objective To make an individualized treatment plan concerning a newborn with meconium aspiration syndrome combined with persistent pulmonary hypertension. Methods Based on the clinical questions raised by a newborn with meconium aspiration syndrome combined with persistent pulmonary hypertension, we searched The Cochrane Library (Issue 3, 2009), MEDLINE (1980 to June 2009), ACP Journal Club (1991 to June 2009), and Chinese Journal Fulltext Database (1994 to June 2009) for systematic reviews, randomized controlled trials (RCTs) and case-control studies. The quality of the included studies was assessed. Results A total of 9 RCTs, 1 health economic evaluation, 1 meta analysis, and 2 systematic reviews were considered eligible. The evidence indicated that the use of ECMO in infants of PPHN had shown a decreased risk of death, but not cost-saving from a societal perspective; iNO treatment could improve the PaO2 and resulted in a reduction in the incidence of requirement for ECMO; there were not randomized controlled trials regarding the treatment of PPHN by hyperventilation, high-frequency ventilation, alkali infusion, pulmonary vasodilators (magnesium sulfate, tolazoline, prostaglandin or prostacyclin, milrinone), surfactant therapy; oral sildenafil could lower oxygenation index (OI) and result in a reduction in the incidence of death. The individualized treatment plans of oral sildenafil were developed based on the available evidence, existing conditions of the hospital, and the values of children with families. After 1 month of treatment, the FiO2 returned to normal and symptoms were alleviated. Conclusion The treatment efficacies and the survival rates in meconium aspiration syndrome combined with PPHN have been improved by determining an individualized treatment plan according to evidence-based methods.
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.
