Ultrasound stethoscope is not a substitute of physical examination

A personal ultrasound imager (ultrasound stethoscope). A revolution in the physical cardiac diagnosis!

By providing an enormous amount of qualitative and quantitative information obtained in a short period of time and its high versatility in application, echocardiography has become the most widely used and costeffective cardiac imaging method. It has contributed significantly to the reduction of cardiovascular misdiagnosis since 1971. Since it is often the best or even the only applicable method...

Guesswork is not a substitute for Entropy

Shannon entropy is often considered as a measure of uncertainty. It is commonly believed that entropy is a good measure of how many guesses it will take to correctly guess a single value generated by a source. This belief is not well founded. We summarise some work in this area, explore how this belief may have arisen via the asymptotic equipartition property and outline a hands-on calculation ...

Point-of-care ultrasound: not a stethoscope-a separate clinical entity.

Ultrasound stethoscopy: a renaissance of the physical examination?

This year marks the 50th anniversary of echocardiography. The evolution of this noninvasive imaging modality has been impressive and has paralleled the rapid developments in microprocessor technology. Together with Doppler assessment of intracardiac haemodynamics, a comprehensive and diagnostic evaluation of most patients suspected of having heart disease is now possible. The method introduced ...

Biochemical investigation is no substitute for clinical examination!

CONTEXT Toxic shock syndrome has been shown previously to be associated with hyperamylasaemia. However, serum amylase levels do not usually exceed three times upper limit of normal in these cases. CASE REPORT We report a case of a young girl of 17 years who presented with upper abdominal pain, severe shock and raised serum amylase level of 3,898 U/L, giving an impression of severe acute pancr...
