Abstract
Retrograde memory loss where many years disappear suddenly from memory is a known but rare form of memory disturbance among young and old subjects. For those whose brain is affected by a known organic damage such as head trauma the time lost from memory is usually not counted in years, but typically hours or sometimes days or weeks. We review in this article current knowledge on retrograde memory loss as we describe the experience of a 31 year old woman who experienced an unusually long form of retrograde amnesia. She developed the memory loss in the wake of disappointment and a life event. At the time she had major depression. Having described the case and presented the results of neuropsychological testing, we associate her story with the state of knowledge on retrograde memory loss.

Abstract
The link between an emotional or physical stresses and an acute cardiac event was first discovered in Japan. Stress-induced cardiomyopathy is defined as transient left ventricular dysfunction associated with apical and mid ventricular contractile abnormalities and sparing of basal segments that mimics acute myocardial infarction. This article presents an overview of this disorder.

Abstract
PURPOSE The purpose of this review is to describe the clinical presentation and pathophysiology of stress-related mucosal bleeding and review the strategies to prevent bleeding. SUMMARY The mortality rate associated with clinically significant stress-related mucosal bleeding is high. Respiratory failure requiring mechanical ventilation for more than 48 hours and coagulopathy are two strong, independent risk factors for bleeding. Splanchnic hypoperfusion is the underlying etiology of stress-related mucosal injury and bleeding. Mucosal damage typically manifests as multiple superficial lesions without perforation, and bleeding often originates in superficial capillaries after the patient is admitted to the intensive care unit. Providing adequate visceral perfusion is vital to preventing bleeding. Gastrointestinal function should be taken into consideration before using enteral nutrition, and enteral nutrition should not be the sole stress ulcer prophylactic therapy. Acid-suppression therapy should be used to raise the intragastric pH above 3.5 because it reduces the incidence of stress-related mucosal bleeding. Proton pump inhibitors are at least as effective, and may be more effective than histamine H2-receptor antagonists in achieving this pH goal and preventing bleeding. CONCLUSION The key to reducing mortality from stress-related bleeding in critically ill patients is to prevent mucosal damage. Providing adequate visceral perfusion and acid-suppression therapy can reduce the risk of stress-related mucosal damage and bleeding.
