Endovascular aneurysm repair: treatment of choice for abdominal aortic aneurysm coincident with horseshoe kidney? three case reports and review of literature

AbstractThere is still controversy as to which surgical method is the most suitable for repair of abdominal aortic aneurysm with concomitant horseshoe kidney (AAA-HSK). We report three cases of AAA-HSK treated with endovascular aneurysm repair. In one of these patients we sacrificed the accessory renal artery by applying coils before the operation. Renal infarction, hypertension, or elevated serum creatinine level was not observed in any of our patients. If the blood supply to the kidneys is taken into consideration, endovascular aneurysm repair is our preferred surgical method for repair of AAA-HSK when anatomic conditions are suitable for stent-graft application and kidney function is normal

A prospective study evaluating the integration of a multifaceted evidence-based medicine curriculum into early years in an undergraduate medical school

BACKGROUND: The importance of ensuring medical students are equipped with the skills to be able to practice evidence-based medicine (EBM) has been increasingly recognized in recent years. However, there is limited information on an effective EBM curriculum for undergraduate medical schools. This study aims to test the feasibility of integrating a multifaceted EBM curriculum in the early years of an undergraduate medical school. This was subsequently evaluated using the validated Fresno test and students' self-reported knowledge and attitudes as they progressed through the curriculum. METHODS: EBM was integrated horizontally and vertically into the curriculum into the first 2 years of undergraduate medical school. First year medical students were recruited to participate in the study. The 212-point Fresno test was administered along with a locally developed questionnaire at baseline before EBM teaching in year one and at the end of EBM teaching in year two. RESULTS: Thirty-one students participated at baseline and 55 students participated at the end of second year EBM teaching. For the 18 students who completed the Fresno at both time points, the average score increased by 38.7 marks (p < 0.001) after EBM teaching. Students felt confident in formulating clinical questions and in critically appraising journal articles after EBM teaching. EBM was perceived to be important to their future practice as a doctor and for improving patient outcomes at both time points. CONCLUSIONS: It has been feasible to integrate a multifaceted, EBM curriculum from the first year of an undergraduate medical program. Early evaluation of the curriculum using the Fresno test has shown a significant increase in students' EBM knowledge. The curriculum also demonstrated an increase in students' perceptions of the clinical relevance of EBM in their developing practice

Guidelines and Safety Practices for Improving Patient Safety

AbstractThis chapter explains why clinical practice guidelines are needed to improve patient safety and how further research into safety practices can successfully influence the guideline development process. There is a description of the structured process by which guidelines that aim to increase the likelihood of a higher score are created. Proposals are made relating to (a) the live updating of individual guideline recommendations and (b) tackling challenges related to the improvement of guidelines

A rare cause of stroke: fail-implanted venous port catheter system – a case report

Background!#!We present the case of a 75-year-old female with acute embolic cerebral infarction caused by a fail-implanted venous port catheter system in the left subclavian artery.!##!Case presentation!#!A 75-year-old woman presented to our emergency room after acute onset of a right-sided hemiparesis and dysarthria. Within 2 days after admission, she developed a left-sided hemiparesis, ataxia with concordant gait disturbance and incoordination of the left upper limb. DWI-MRI showed acute multiple infarcts in both cerebral and cerebellar hemispheres. Laboratory examination, 24-h Holter electrocardiography and transthoracic echocardiography provided no pathological findings. Further examination revealed an arterially fail-implanted port catheter, placed in the left subclavian artery with its tip overlying the ascending aorta, as the source of cerebral embolism.!##!Conclusion!#!This is the first case report of thromboembolic, cerebral infarction due to a misplaced venous port catheter in the subclavian artery, emphasizing the imperative need for a thorough diagnostic workup, when embolism is suspected but cannot be proven at first glance
