Chemotherapy induced toxicities in therapeutic trials of Acute Lymphoblastic Leukaemia.

It is common practice in therapeutic trials in Acute Lymphoblastic Leukaemia (ALL) to treat chemotherapy induced toxicities. In this study, 50 newly diagnosed ALL patients were enrolled and the median age was 14.5 years. 32 patients were male and 18 female. Prognostic factors were analysed. Remission induction, consolidation and maintenance therapy with conventional combination chemotherapy and CNS prophylaxis with intrathecal methotrexate and radiotherapy were instituted to all patients for long term event free survival. Results of induction therapy and overall outcomes of treatment were observed. Chemotherapy induced toxicities were also detected and treated accordingly. These toxicities were described in 4 groups depending on the frequency of their development in chemotherapy received patients. Haematological and gastrointestinal side effects and alopecia were expected i.e., developed in >75% of patients. Prednisolone and vincristine induced toxicities were common i.e., observed in >25% of patients. Hepatic complications and anthracycline induced tachycardia were occasional i.e., occurred in <25% and localized phlebitis and/ or soft tissue necrosis were rare and accidental i.e., developed in 5% of patients.

Correlation of ultrasonographic findings with ultrasound guided fine needle aspiration of liver lesion.

Ultrasonographic findings of liver were correlated with cytological findings in a series of 50 patients. Multiple lesions described by ultrasonography and suggested as HCC/TB were proved to be metastatic in 60% cases and hepatocellular carcinoma in 40% cases by cytological examination. Multiple lesions suggested as metastatic lesions in ultrasonography was proved as such by cytology in 83% cases. Solitary lesion suggested as neoplastic in ultrasonography was proved as such in cytology in 90% cases. Of the 2 patients suggested as diffuse parenchymal lesion revealed cytological findings of cirrhosis in one case and that of TB in other. Serum alpha-feto protein and Carcinoembryogenic antigen (CEA) was done in all the cases. Serum alpha-feto protein was higher in hepatocellular carcinoma and CEA was higher in metastatic lesions. Ultrasound guided fine needle aspiration of liver can play more role in diagnosis and classification of liver disease than ultrasonographic comment alone, as it requires greater degree of precision to reach diagnostic accuracy.

Effect of high protein carbohydrate free diet on the evolution of diabetes mellitus in rats.

Diabetes was induced in seventy seven Long Evans rats of both sexes by injecting streptozotocin (STZ). Some of these diabetic rats were provided with a high protein-carbohydrate (HP-CHO) free diet. The diabetic state of the rats on HP-CHO free diet was compared with that of the diabetic rats on normal diet and the control rats on normal diet. Diabetic state was assessed through the diet consumption, body weight changes, urinary glucose loss and blood glucose estimation. From the fifth day the rats on HP-CHO free diet showed significant reduction of blood glucose level and urinary glucose loss.
