Clostridium difficile-associated disease (CDAD) has been clearly associated with the use of broad-spectrum antibiotics worldwide. However, information about CDAD is scarce in Mexico and Latin America. ⋯ The use of H2 blockers, age < 65 years, prior hospitalization or earlier use of cephalosporins or fluoroquinolones, as well as stay at the ICU were independent risk factor for CDAD.

To assess the outcome of patients with clinically localized prostate cancer (PCa) and seminal vesicle invasion (SVI) in the radical prostatectomy (RP) specimen. ⋯ In the present study, the frequency of SVI was 18.9%. SVI confers a poor prognosis. Preoperative PSA > or =10 ng/mL was associated to the risk of biochemical recurrence.

Interferons are a family of pleiotropic cytokines, their name was assigned because of their anti-replicative viral activity. IFNgamma or immune type II interferon does not share receptors with the type I interferon, its structure is different and its gene is located in different chromosome, although its biologic effects are similar. Along of several years of research, it has been found that IFNgamma enhances the transcription of genes involved in immunomodulation, antiviral responses and antitumoral activities. ⋯ Indeed, this cytokine has a key role in the control of bacterial, micotic, viral and parasitic infections. Depending of the micro-environment, IFNgamma has a dual role as pro or anti inflammatory cytokine. Novel therapeutic strategies are currently being developed with the aim to enhance the immune response or replace IFNgamma gene abnormal expression with beneficial results in humans, being recombinant IFNgamma safe and well tolerated.
