Annuloaortic ectasia (AAE), in which there is an idiopathic aortic root dilation leading to pure aortic regurgitaion (AR), is a rare disorder and is usually seen as a forme--fruste of Marfan's syndrome. We report a case in which the patient presented with rapid onset of symptoms of heart failure and was being treated for mitral regurgitation due to dilated cardiomyopathy. Postmortem findings revealed an enlarged heart with annuloaortic ectasia.
Human stool samples are the most widely used source of E. histolytica cysts for diagnosis and research. Cysts concentrated from faecal samples are contaminated with faecal debris and bacteria and are unsuitable for use as antigens. Other gradient purification and sedimentation procedures result in considerable cyst losses. We present an effective and simple purification procedure using varying densities of Percoll that yields an adequate cyst concentration from a moderate cyst load in a single stool sample.
