Here we present two cases of acute hepatic failure, one due to classic heat shock, while the other occurred while the patient was doing a marathon-type running. Both cases presented with very high transaminases and significantly elevated international normalized ratio （INR）. No other causes for liver failure could be identified but physical exhaustion and hyperthermia.展开更多

Prompt diagnosis or exclusion of HF and its cause and precipitating factors can improve the quality and efficiency of care, shorten hospital stay, reduce readmission and improve prognosis. While the clinician remains central to reaching a clinical diagnosis of heart failure, the use of traditional and novel diagnostic technologies will improve the specificity and sensitivity of the diagnosis of heart failure diagnosis and provide insights into its pathophysiogical profile and help tailor therapy to individual patient need. Chest X-rays and electrocardiograms are generally available;echocardiograms less so. Novel technologies include both invasive and non-invasive methods to detect increases in intrathoracic fluid, pulmonary congestion, left ventricular filling pressures, cardiac output and vascular function. However, few of these technologies have been subjected to randomised controlled trials investigating their ability to improve patient management.展开更多
