Brain abscesses in a patient with a patent foramen ovale: a case report
<p>Abstract</p> <p>Introduction</p> <p>Brain abscesses arising from right-to-left cardiac shunting are very rare in adults.</p> <p>Case presentation</p> <p>We describe the case of a 47-year-old non-hispanic white male with periodontal disease who developed several brain abscesses caused by <it>Streptococcus intermedius</it>. A comprehensive workup revealed a patent foramen ovale with oral flora as the only plausible explanation for the brain abscesses.</p> <p>Conclusion</p> <p>Based on this case and the relevant literature, we suggest an association between a silent patent foramen ovale, paradoxical microbial dissemination to the brain, and the development of brain abscesses.</p
Adult brain abscess associated with patent foramen ovale: a case report
Brain abscess results from local or metastatic septic spread to the brain. The primary infectious site is often undetected, more commonly so when it is distant. Unlike pediatric congenital heart disease, minor intracardiac right-to-left shunting due to patent foramen ovale has not been appreciated as a cause of brain abscess in adults. Here we present a case of brain abscess associated with a patent foramen ovale in a 53-year old man with dental-gingival sepsis treated in the intensive care unit. Based on this case and the relevant literature we suggest a link between a silent patent foramen ovale, paradoxic pathogen dissemination to the brain, and development of brain abscess
Successful Treatment of Novel H1N1 Influenza related Fulminant Myocarditis with Extracorporeal Life Support
The prevalence of myocardial involvement in influenza infection ranges from 0% to 12%. The 2009 pH1N1 influenza virus, formerly known as swine flu, first appeared in Mexico and the United States of America in March and April 2009 and has swept the globe with unprecedented speed. We report a case of fulminant myocarditis associated with this virus treated successfully using extra-corporal membrane oxygenator
How to misuse echo contrast
<p>Abstract</p> <p>Background</p> <p>Primary intracardiac tumours are rare, there are however several entities that can mimic tumours. Contrast echocardiography has been suggested to aid the differentiation of various suspected masses. We present a case where transthoracic echocardiography completely misdiagnosed a left atrial mass, partly due to use of echo contrast.</p> <p>Case presentation</p> <p>An 80 year-old woman was referred for transthoracic echocardiography because of one-month duration of worsening of dyspnoea. Transthoracic echocardiography displayed a large echodense mass in the left atrium. Intravenous injection of contrast (SonoVue, Bracco Inc., It) indicated contrast-enhancement of the structure, suggesting tumour. Transesophageal echocardiography revealed, however, a completely normal finding in the left atrium. Subsequent gastroscopy examination showed a hiatal hernia.</p> <p>Conclusion</p> <p>It is noteworthy that the transthoracic echocardiographic exam completely misdiagnosed what seemed like a left atrial mass, which in part was an effect of the use of echo contrast. This example highlights that liberal use of transoesophageal echocardiography is often warranted if optimal display of cardiac structures is desired.</p
