RESUMO
A pilot study of transrectal fine needle aspiration biopsy was conducted in 44 patients, above the age of 50 years, who presented with features of obstructive uropathy during a one year period between August 1990 and April 1991. Histopathological study was carried out in 23 out of 44 patients, who underwent total prostatectomy or transurethral resection following the aspiration biopsy procedure. In 21 patients FNAB by the transrectal route could not be obtained because of technical difficulties; therefore intraoperative scrape cytology was studied prior to histopathology, of the fresh prostatic specimen. A good cytohistopathological correlation was obtained by both methods; an accuracy of 95.6% and 95.2% with FNAC and scrape respectively. A wide range of benign and malignant lesions were studied.

A 50 year old male presented with massive lymphadenopathy and was found to be in extramedullary blast crisis is reported. Lymphadenopathy regressed on busulphan therapy and the overt blast crisis took 15 months to occur after initial presentation.

Severe heat stress experienced by aircrew during summer months can cause deterioration in performance. Acute heat stress can also lead to dehydration and loss of electrolytes. Previous studies emphasised the need of K+ replacement. This study was carried out to determine the effect of glucose electrolyte ingestion (ELECTRAL) on thermal strain parameters. Ten healthy male subjects in the age group of 19-43 years were exposed to an acute thermal environment of 50 degrees C Tdb with relative humidity of 30% for 40 min. twice each day on two different days with an interval of one hour in between the exposures. At the beginning of rest period electrolyte solution was ingested during electrolyte trials and water under control trials. Physiological parameters of Tsk, T or, HR and electrolyte concentration of Na+ and K+ in sweat did not show any significant difference in both the trials. Sweat loss was significantly higher during electrolyte trials.
