Computer-assisted semen analysis parameters in men with varicocele: is surgery helpful?
Computer-assisted semen analysis provides the potential for accurate quantitative evaluation of semen in men with varicocele. Varicocelectomy results in improvement in semen quality with pregnancy rates of 50%.
Two hours of servoflurane and mechanical ventilation using a tidal volume of 10 ml/kg is associated with remarkable changes in the immune response in infants without preexisting lung pathology undergoing cardiac catheterization. In the lungs the immune balance favors a proinflammatory response pattern without detectable concentrations of anti-inflammatory mediators. The Th1 immune response by peripheral blood leukocytes was decreased. The observed change in Th1/Th2 balance in favor of Th2 cytokine activity may be a systemic adaptation to the proinflammatory milieu in the lung.
