Background: The serum PSA (sPSA) test has low specificity for prostate cancer (PCa), since sPSA also rises in benign prostatic hyperplasia (BPH). Serum PSP94 (sPSP94), a major secreted prostate protein, is indicated as a PCa marker. The potential of sPSP94 and sPSA in conjunction with each other to improve specificity of diagnostic test for PCa needs to be evaluated. Methods: PCa patients (n. = 33), BPH patients (n. = 44) and healthy controls (n. = 50) were recruited. A serum-based sandwich ELISA was developed to measure sPSP94 concentrations. Utility of sPSP94 in improving specificity of sPSA test was evaluated by studying sPSP94/sPSA ratios of study participants. Results: Considerable decrease in overlap among sPSP94/sPSA ratio values of BPH and PCa patients was observed, as compared to sPSP94 or sPSA alone. For differentiating between BPH and PCa patients, this ratio had a maximum area under the curve (AUC) of 0.859 (P= 0.0132) and had a comparable sensitivity (90.91%) to sPSA with an increased specificity of 70.45%. Further, decision curve analysis (DCA) showed that sPSP94/sPSA ratio had a superior net benefit in identifying PCa, in patients opting for biopsy. Conclusion: The sPSP94/sPSA ratio can be a better differentiating marker between BPH and PCa, than sPSP94 or sPSA alone. © 2014 Elsevier B.V.

Cannabis in its various forms has been known since time immemorial, the use of which has been rising steadily in India. 'Bad trips' have been documented after cannabis use, manifestations ranging from vague anxiety and fear to profoundly disturbing states of terror and psychosis. Cannabis is known to affect various neurotransmitters, but 'bad trip' due to its anticholinergic effect has never been described in literature to the best of author's knowledge. Hereby, the author describes a case of a young adult male experiencing profound anticholinergic effects after being exposed for the first time in his life to bhang, a local oral preparation of cannabis. © 2013 Elsevier Inc..

Various host factors such as cytokines and HLA, regulate the immune system and influence HIV transmission to infants exposed to HIV-1 through their mothers. Tumor Necrosis Factor Alpha (TNF-α) is a strong pro-inflammatory mediator and thought to influence vulnerability to HIV infection (and/or) transmission. Polymorphisms in regulatory regions are known to govern the production of this cytokine. However, the association of these variations in perinatal HIV transmission is yet to be established. Present study aimed to evaluate if polymorphisms in promoter region of TNF-α gene is associated with perinatal HIV transmission. With informed consent from parents, infants' blood was collected for HIV screening and SNPs analysis at 2 loci: TNF (rs1800629) and TNF (rs361525) using PCR-SSP method. HIV positive (n = 27) and negative (n = 54) children at the end of 18th month follow up were considered for this study. GG genotype, responsible for low expression of TNF (rs1800629) was significantly (p = 0.005) higher in uninfected children, while higher GA genotype frequency was observed in infected children. The 'G' allele frequency was significantly higher in negative children (p = 0.016). We conclude that genotypic variants of TNF (rs1800629) are a likely contributor to perinatal HIV transmission. This provides new insights in markers of differential susceptibility to perinatal HIV transmission. © 2014 Elsevier Ltd.
