1Vascular calcification:When should we interfere in chronic kidney disease patients and how?显示文摘Chronic kidney disease(CKD) patients are endangered with the highest mortality rate compared to other chronic diseases. Cardiovascular events account for up to 60% of the fatalities. Cardiovascular calcifications affect most of the CKD patients. Most of this calcification is related to disturbed renal phosphate handling. Fibroblast growth factor 23 and klotho deficiency were incriminated in the pathogenesis of vascular calcification through different mechanisms including their effects on endothelium and arterial wall smooth muscle cells. In addition, deficient klotho gene expression, a constant feature of CKD, promotes vascular pathology and shares in progression of the CKD. The role of gut in the etio-pathogenesis of systemic inflammation and vascular calcification is a newly discovered mechanism. This review will cover the medical history, prevalence, pathogenesis, clinical relevance, different tools used to diagnose, the ideal timing to prevent or to withhold the progression of vascular calcification and the different medications and medical procedures that can help to prolong the survival of CKD patients.Usama Abdel Azim Sharaf El Din Mona Mansour Salem Dina Ossama Abdulazim 2016World Journal of Nephrology2016,5,5:10
2Trauma patterns in patients attending the Emergency Department of Jazan General Hospital, Saudi Arabia显示文摘BACKGROUND: Modern civilization and the sharp rise in living standards have led to dramatic changes in trauma pattern in Saudi Arabia. This study aimed to describe the different patterns of injuries of patients attending the Emergency Department of Jazan General Hospital(JGH) in the southwest corner of Saudi Arabia.METHODS: A total number of 1 050 patients were enrolled in the study. A pre-organized data sheet was prepared for each patient attended the Emergency Department of JGH from February 2012 to January 2013. It contains data about socio-demographics, trauma data, clinical evaluation results, investigations as well as treatment strategies.RESULTS: The mean age of the patients was 25.3±16.8 years. Most(45.1%) of the patients were at age of 18–30 years. Males(64.3%) were affected by trauma more common than females. More than half(60.6%) of the patients were from urban areas. The commonest kind of injury was minor injury(60%), followed by blunt trauma(30.9%) and then penetrating trauma(9.1%). The mean time from the incident to arrival at hospital was 41.3±79.8 minutes. The majority(48.2%) of the patients were discharged after management of trivial trauma, whereas 2.3% were admitted to ICU, 7.7% transferred to inpatient wards, and 17.7% observed and subsequently discharged. The mortality rate of the patients was 2.6%.CONCLUSION: Trauma is a major health problem, especially in the young population in Saudi Arabia. Blunt trauma is more frequent than penetrating trauma, with road traffic accidents accounting for the majority.Emad Hokkam Abdelaziz Gonna Ossama Zakaria Amany El-shemally 2015World Journal of Emergency Medicine2015,6,1:7
3Stop chronic kidney disease progression: Time is approaching显示文摘Progression of chronic kidney disease(CKD) is inevitable. However, the last decade has witnessed tremendous achievements in this field. Today we are optimistic; the dream of withholding this progression is about to be realistic. The recent discoveries in the field of CKD management involved most of the individual diseases leading the patients to end-stage renal disease. Most of these advances involved patients suffering diabetic kidney disease, chronic glomerulonephritis, polycystic kidney disease, renal amyloidosis and chronic tubulointerstitial disease. The chronic systemic inflammatory status and increased oxidative stress were also investigated. This inflammatory status influences the antisenescence Klotho gene expression. The role of Klotho in CKD progression together with its therapeutic value are explored. The role of gut as a major source of inflammation, the pathogenesis of intestinal mucosal barrier damage, the role of intestinal alkaline phosphatase and the dietary and therapeutic implications add a novel therapeutic tool to delay CKD progression.Usama Abdel Azim Sharaf El Din Mona Mansour Salem Dina Ossama Abdulazim 2016World Journal of Nephrology2016,5,3:6

5Multi-modality imaging of cardiac amyloidosis: Contemporary update显示文摘Cardiac amyloidosis is a heterogeneous and challenging diagnostic disease with poor prognosis that is now being altered by introduction of new therapies.Echocardiography remains the first-line imaging tool, and when disease is suspected on echocardiography, cardiac magnetic resonance imaging and nuclear imaging play critical roles in the non-invasive diagnosis and evaluation of cardiac amyloidosis. Advances in multi-modality cardiac imaging allowing earlier diagnosis and initiation of novel therapies have significantly improved the outcomes in these patients. Cardiac imaging also plays important roles in the risk stratification of patients presenting with cardiac amyloidosis. In the current review, we provide a clinical and imaging focused update, and importantly outline the imaging protocols, diagnostic and prognostic utility of multimodality cardiac imaging in the assessment of cardiac amyloidosis.Tom Kai Ming Wang Ossama K Abou Hassan Wael Jaber Bo Xu 2020World Journal of Radiology2020,12,6:2
