To improve proper application of evidence in clinical practice．six relevant problems were reviewed．The problems included：① How to evaluate and use evidence from systenaatic reviews of randomized controlled trials?② How to evaluate and use evidence from randomized controlled trials?③ How to evaluate and use evidence from non—randomized controled trials?④ How to evaluate and use evidence from case series?⑤ How to evaluate and use expert opinions?⑥ How to evaluate and use chnical practice guidelines?
To help better understanding on evidence-based medicine, five frequently asked questions relevant to evidence-based clinical practice were commented on. The questions included: 1. Dose evidence-based medicine only emphasize evidence and ignore clinical experiences? 2. Dose evidence only include randomized controlled trials and systematic reviews? 3. How to face the quality of evidence? 4. Is randomized evidence suitable for treating individual patient? 5. Is evidence-based medicine useless since there is no adequate evidence for many clinical questions?
This article reviews the progress, problems and future development of evidence-based neurology; introduces sources of clinical evidence and evidence-based recommendations on some common neurological disorders from the Quality Standards Subcommittee of the American Academy of Neurology. It promotes high quality clinical research to provide good evidence and the use of current best evidence in patient care.
Objective To explore whether there is enough clinical evidence to confirm that stereotactic aspiration does more good than harm in patients with cerebral hemorrhage. Method A systematic review of all relevant clinical studies on stereotactic aspiration in the treatment of cerebral hemorrhage. Results Eight randomized controlled trials (RCTs) including 757 patients and 17 nonrandomized controlled studies including 1 766 patients, as well as 20 uncontrolled studies including 1 244 patients were identified . All studies reported positive results regarding the effects. However, the quality of the included studies were generally poor. The main problem was that most trials reported them as a RCT, but no description of the method of randomization. Conclusions Stereotactic aspiration in the treatment of cerebral hemorrhage is promising based on present evidence. However, at present, we can not draw definite conclusion whether the treatment does more good than harm compared with noninvasive medical treatment because of the poor quality of included studies. Therefore, more high quality RCTs are required.
The application of dopamine agonists in Parkinson’s disease has been a hot topic in recent years. Can dopamine receptor agonists serve as the initial drugs for Parkinson’s disease? Does it improve the natural history of patients? Has it neuroprotective role? When and how to use dopamine receptor agonists? This article provides evidence on the pros and cons of dopamine receptor agonists in the treatment of Parkinson’s disease for helping clinical decision making.
Hot flashes are a common syndrome in postmenopausal women. The treatment is complex and different for specific patients. A clinical case and hormonal replacement therapy selection are provided to show evidence-based practice in this field.
Infectious bone defects are usually caused by trauma, surgical infections, or chronic osteomyelitis, and represent a complex and intractable clinical challenge in the field of orthopaedics. Biological scaffolds can achieve synergistic repair of defects by loading antibiotics for controlled release to inhibit bacteria, providing support for cell proliferation and differentiation to promote bone regeneration, and carrying factors or stem cells to enhance vascularization. They possess incomparable advantages over traditional treatment methods in the management of infectious bone defects, and the selection of appropriate biological scaffolds in clinical practice needs to be tailored to the type of defect and the severity of infection. Therefore, this article elaborates on the application and research progress of biological scaffolds in the treatment of infectious bone defects.
Objective To investigate the current situation of clinical studies on puerarin for ischemic stroke and the reliability of these evidence. Methods By electronic searching and handsearching, we collected all the published clinical study reports on puerarin for ischemic stroke and assessed all the included reports according to clinical epidemiologic standard. Results 35 RCTs, 22 non-randomized controlled trials and 17 case serials studies were included and analysed. Conclusions Current quality of clinical studies of puerarin for ischemic stroke is not good enough to provide reliable evidence.
Ischemic lesions, lacunar infarcts and leukoaraiosis on head CT or MRI are commonly detected in patients with non-specific symptoms such as dizziness and headache or people undergoing healthy physical examinations. Although these imaging findings are mostly related to vascular disease, especially cerebral small vessel disease, it does not mean that long-term use of antiplatelet drugs and statins are required. On the basis of literature review and clinical experiences, the article points out that the treatment methods for such manifestations include determining whether these lesions are vascular lesions, searching for risk factors or causes such as aging, hypertension, diabetes mellitus, vascular stenosis, and psychological factors, and taking strategies for the corresponding prevention and management, provides a reference for the appropriate diagnosis and treatment of these imaging manifestations in clinical practice.
Objective To investigate the application value of the binding pancreaticogastrostomy in pancreatico-duodenectomy. Methods The clinical data of 13 patients that performed pancreaticoduodenectomy with binding pancr-eaticogastrostomy from Jan. 2010 to Mar. 2013 in our hospital were retrospectively analyzed. The incidence of postoper-ative complications were counted. Results There was 1 patient with pancreatic stump bleeding after operation， and then recovered after conservative treatment. There was no patient with pancreatic fistula， bile fistula， delayed gastric empt-ying， and other complications after operation in whole group. Peritoneal fluid and amylase level in peritoneal fluid were gradually reduced or degraded after operation. The gastrointestinal function was recovered better. All patients were compl-etely cured. Conclusion The binding pancreaticogastrostomy in pancreaticoduodenectomy has its own unique advantage.It could be reduce the incidence of pancreatic fistula in postoperative patients by using binding pancreaticogastrostomy reasonably.
