RESUMEN
A reaction for NADH tetrazolium reductase was used to demonstrate the presence of ganglion cells in myenteric plexus during dysganglionic bowel operations in 24 patients. The advantages of this method are the quick preparation of an incubation medium, a short incubation time and the good demonstration of ganglion cells. It was possible to determine the extent of the aganglionic and prominently hypoganglionic parts of the bowel and in this way achieve improved results. The NADH tetrazolium reductase reaction can be recommended for the perioperative biopsy of a dysganglionic bowel.

The pulsed Doppler echocardiography (PDE) was used to evaluate the character of mitral valve flow in a large atrial tumor. The tumor obstructed the mitral orifice during diastole. PDE findings, however, showed normal triphasic diastolic flow within the actual mitral orifice and no changes typical for mitral stenosis. The same turbulence pattern as in mitral stenosis was detected in the left ventricle. In addition, PDE revealed the presence of mild mitral regurgitation in agreement with angiography.

A 3-month old infant was found to suffer from a solid painless soft tissue swelling situated in his left scapular region and accompanied by pronounced anaemia and raised erythrocyte sedimentation rate. The ominous clinical course as well as X-ray pictures of the scapula gave rise to a suspicion of a malignant tumour development. Biopsy from the surface of the bone gave no unambiguous answer. A histological examination of the whole surgically removed shoulder blade revealed the presence of infantile cortical hyperostosis.
