We report an infant with congenital tuberculosis who presented with fulminant septic shock, disseminated intravascular coagulation and respiratory failure. Aggressive resuscitation and supportive care and prompt initiation of antituberculosis medications led to resolution of the shock state. We reviewed six other cases with a similar presentation.(More)
The effect of hyperglycemia upon susceptibility to bacterial infection in diabetes mellitus is incompletely elucidated. The present experiments assessed the effect of hyperglycemia upon neutrophil-mediated phagocytosis of type III group B Streptococcus (GBS). Type III GBS was chosen for study because the incidence of invasive GBS disease is substantially(More)
This paper studies, for a differential variational inequality involving a locally prox-regular set, a regularization process with a family of classical differential equations whose solutions converge to the solution of the differential variational inequality. The concept of local prox-regularity will be termed in a quantified way, as (r, α)-prox-regularity.
We study a minimal time control problem under the presence of a saturation point on the singular locus. The system describes a fed-batch reactor with one species and one substrate. Our aim is to find an optimal feedback control steering the system to a given target in minimal time. The growth function is of Haldane type implying the existence of a singular(More)
We address the problem of finding an optimal feedback control for feeding a fed-batch bioreactor with one species and one substrate, from a given initial condition to a given target value in a minimal amount of time. Mortality rate for the biomass and nutrient recycling are taken into account in this work. The optimal synthesis (optimal feeding strategy)(More)
In this paper, we consider an optimal control problem for a system describing a fed-batch bioreactor with one species and one substrate. Our aim is to find an optimal feedback control in order to steer the system to a given target in minimal time. The growth function is of Haldane type implying the existence of a singular arc. Unlike many studies on the(More)
This paper is devoted on the one hand to the study of specific properties of an evolution variational inequality, holding in the Hilbert setting. We give on the other hand a general criterion for Lyapunov pairs of this dynamical system and some results on the asymptotic behaviour of the solution. Key-words: Differential inclusions Evolution variational(More)
