Pathological autopsy: Most valuable aid in the present medical and medico-legal scenario.

It is a fact that the advancements in medicine would not have been possible without the help of autopsies, may be pathological or clinical or medico-legal. Mankind has been immensely benefited by the autopsies all these years. With the changing disease patterns, re emerging diseases, environment and social system, autopsies have become more necessary and relevant than before. The objectives of an autopsy examination are not being achieved at the highest level due to under trained medical officers who handle more than 80% of autopsy work in India and also due to the unwillingness or inertia of pathologists or clinicians to perform the autopsies. Here the in this article we try to highlight the contributions of pathological autopsies to the medical sciences & our social system. We also discuss why there is urgent need for more and well organized clinical or pathological autopsies through out the nation.

Metabolism of proteins and glycoproteins in tumour bearing mice treated with Aeromonas L-asparaginase.

L-asparaginase, isolated in our laboratory, from Aeromonas had been found to be antileukaemic. In the present study, changes in the levels of proteins and glycoproteins in leukaemic mice and under treatment with Aeromonas L-asparaginase have been compared. Levels of protein bound hexose, fucose and sialic acid which were increased during leukaemia attained normal levels when treated with L-asparaginase. The increased blood urea level declined significantly during enzyme therapy. Effects of L-asparaginase are compared with 'Leunase', a commercially available drug used in the treatment of leukaemia.

Acute renal failure in asphyxiated newborns.

The study was undertaken to evaluate the occurrence of renal failure following perinatal asphyxia in the newborns. Thirty newborns with severe birth asphyxia were included in the study along with 30 normal newborns who comprised the control group. Any neonate presenting with oliguria or blood urea more than 40 mg/dl or creatinine more than 1 mg/dl was subjected to a fluid and diuretic challenge. If oliguria or renal dysfunction persisted then the child was labelled as renal failure and these subjects were further investigated. It was observed that 43% of asphyxiated babies developed acute renal failure (ARF); 69.2% babies had oliguric renal failure. While no significant correlation could be seen between Apgar scores at 5 and 10 min and development of ARF, a significant relationship was seen between hypoxic-ischemic encephalopathy and ARF. Patients with oliguric ARF carried a poorer prognosis as compared to non-oliguric ARF.

Renal dysfunction in septicemic newborns.

The study was undertaken to assess the association and incidence of acute renal failure (ARF) in septicemic neonates. Thirty neonates with septicemia formed the subject matter. Neonates with renal dysfunction were labelled as ARF patients after non responsiveness to a fluid and a diuretic challenge. Renal function tests were also evaluated. Nearly 15% neonates with septicemia developed ARF which was predominantly oliguric in type. The mortality rate in the septicemic neonates with ARF was significantly high. Further the mortality in neonates with oliguric ARF was significantly higher than those with non-oliguric ARF.
