Virtual cystoscopy: reality in imaging of bladder tuberculosis.

We present a case of urinary tuberculosis investigated initially by ultrasound and multidetector computed tomography (MDCT). The MDCT-derived volumetric data were used to generate virtual cystoscopy (VC) images, which revealed a bladder ulcer. The presence of this ulcer was confirmed by conventional cystoscopy-guided biopsy and there was good agreement regarding various features of the ulcer, such as the site, size and shape, as detected by virtual and conventional cystoscopies. VC, a result of simple postprocessing of preacquired MDCT data, proved valuable in the characterization of the bladder lesion in conjunction with CT and ultrasound images. Although a larger study is warranted, in our case these en face VC representations of the ulcer served as useful precursors to conventional cystoscopic biopsy.

Tenolol in angina pectoris.

Selective Beta Blocker Tenolol (IPCA) 50 mg. (A50) and 100 mg. (A100) single dose drug therapy was tried in 25 cases of angina pectoris. Hypertensives were excluded from trial. There were 4 diabetics. Drug trial over a period of 4 weeks revealed subjective and objective improvement with A50 and A100 assessed at the end of 2 and 4 weeks. The average angina attacks/2 wks. was 13.12 +/- 11.26 in basal state whereas the reduction in angina attacks was 6.285 +/- 8.80 with Tenolol 50 mg. and 3.72 +/- 2.86 with 100 mg which was statistically significant. Objective assessment of each patient done by Computerised Stress Test (CST) at the end of 2 and 4 weeks of Tenolol 50 mg and 100 mg revealed statistically significant improvement in their ST depression i.e. 3.645 +/- 1.463 mm basal ST depression, 1.692 +/- 1.680 after Tenolol 50 mg and 2.318 +/- 1.270 after Tenolol 100 mg. There was statistically significant fall in systolic BP (SBP) and double product (DP) both with A50 and 100 mg. Only one patient had slow ventricular tachycardia and mild hypotension during CST.
