RESUMO

Rapid diagnosis of histopathological material is becoming increasingly desirable. In neuropathology, crush smear preparation and frozen section diagnosis of tissues removed during operative procedures, have remained as essential tools for rapid diagnosis. Microwave technology has been introduced into the field of tissue processing and staining in past decade. Now-a-days even automated microwave assisted rapid tissue processors are available. In our study we have analysed the use of a domestic microwave (cost approximately Rs.5000) for urgent histoprocessing (30 minutes). This could be useful in small laboratories or the ones which are in the phase of establishing the department as the procedure is much more economical than obtaining a frozen section (which requires a cryostat worth 3-6 lakhs) and the interpretation of the section obtained does not require any extra experience as these resemble the routinely processed tissue sections. The advantages and limitations of the procedure have been discussed.

RESUMO

Forty patients with dinical diagnosis of lumbar disc herniation were evaluated with myelography and CT scan. Myelography diagnosed lumbar disc hemiation at 59 levels in 40 patients, while CT diagnosed disc hemiation at 64 levels. Lumbar disc hemiation was confirmed peroperatively in 30 out of 40 patients at 48 levels. Myelography correctly diagnosed 43 levels out of 48 levels and thus had a sensitivity of 89.6 per cent. CT diagnosed all the 48 levels correctly with a sensitivity of 100 per cent. Thus CT is super to conventional myelography in the diagnosis of lumbar disc herniation. However, conventional myelography supplements CT examination by limiting the number of scans to the level of interest and thus reduces radiation exposure.
