Mitral valve prolapse is a common valvular abnormality that is caused by myxomatous degeneration, characterized macroscopically by leaflet thickening and redundancy accompanied with histologically marked proliferation of the spongiosa and mucopolysaccharide acid replacement of leaflet collagen in the prolapse leaflets. Nevertheless, the discrepant natural history and various concomitant syndrom...
The unique enhanced sensitivity of vibrational circular dichroism (VCD) to the formation and development of amyloid fibrils in solution is extended to four additional fibril-forming proteins or peptides where it is shown that the sign of the fibril VCD pattern correlates with the sense of supramolecular filament chirality and, without exception, to the dominant fibril morphology as observed in ...
A 57-year-old man with type II mixed cryoglobulinaemia presented to the emergency department with a history of worsening lethargy, malaise and non-drenching night sweats in a relapsing-remitting pattern. He was diagnosed with type II mixed cryoglobulinaemia 7 months ago following episodes of fever, night sweats, lethargy and malaise associated with a non-blanching, purpuric, raised erythematous...
Cardiac platypnoea-orthodeoxia syndrome (POS) is a position-dependent condition of dyspnoea and hypoxaemia due to right-to-left shunting. It often remains unrecognised in clinical practice, possibly because of its complex underlying pathophysiology. We present four consecutive patients with POS and patent foramen ovale (PFO) who underwent a successful percutaneous PFO closure, describe the mech...
OBJECTIVE To determine the frequency that diabetes is reported on death certificates of decedents with known diabetes and describe trends in reporting over 8 years. RESEARCH DESIGN AND METHODS Data were obtained from 11,927 participants with diabetes who were enrolled in Translating Research into Action for Diabetes, a multicenter prospective observational study of diabetes care in managed ca...
Background: Vertebrobasilar dolichoectasia is defined as a prominent elongation, dilatation and tortuosity of the vertebral and basilar arteries. Ectatic basilar arteries may cause different neurological symptoms by several mechanisms including compressive effects and embolic or ischemic events. Case presentation: In this report we present a 58-year old female patient who was admitted in Dr. S...
BACKGROUND Previous analyses derived the relative risk (RR) of dying as a result of low weight-for-age and calculated the proportion of child deaths worldwide attributable to underweight. OBJECTIVES The objectives were to examine whether the risk of dying because of underweight varies by cause of death and to estimate the fraction of deaths by cause attributable to underweight. DESIGN Data ...
