Relative contribution of digital rectal examination and transrectal ultrasonography in interpreting serum prostate-specific antigen values for screening prostate cancer in Arab men.

Background: This study was conducted to determine the utility of digital rectal examination (DRE), transrectal ultrasonography (TRUS) and serum prostate-specific antigen (PSA) in the diagnosis of prostate cancer in men in Arabia, an are of the world with a relatively low incidence of this disease.

Patients And Methods: 329 patients suspected of having prostate cancer on account of raised serum PSA level (>4 ng/ml), DRE or TRUS findings, underwent TRUS-guided prostate biopsy. Raised PSA individually as well as combined, or a lesion suspicious of carcinoma on DRE or TRUS was recorded as PSA(+), DRE(+) or TRUS(+), respectively.

Correlation of clinical and laboratory surrogate markers of immunodepletion with T cell subsets (CD4 & CD8) determined flow cytometrically in HIV infected patients: a hospital based study.

CD4 count is established in HIV medicine as a marker of immune depletion. However, due to financial constraints this facility is not readily available in India. Therefore, this cross sectional study in the setting of a government hospital in Pune evaluated 72 HIV infected patients for the surrogate markers of CD4 count by correlating CD counts with clinical and easily available laboratory parameters.
