Acinetobacter baumannii is a Gram-negative coccobacillus that has emerged as a troublesome pathogen causing institutional outbreaks. Environmental contamination is a distinctive characteristic of this microorganism, which brings a further difficulty in infection control. During A. baumannii outbreaks in intensive care units, a common contaminated object can be found as a reservoir. Finding out this source by epidemiological investigations is of particular importance in order to develop effective interventions. We describe an outbreak of A. baumannii and the results of epidemiological investigations in a neonatal intensive care unit. The outbreak strain was isolated from the outer surface of a breastmilk pump. We have successfully controlled the outbreak by careful reviewing of our milk collection process.
Although closure of ductus arteriosus requires multiple intriguing cell signalling pathways, current treatment options merely act through cyclooxygenase inhibition. Expectedly, medical management of ductus arteriosus is quite far away from optimum and there is an ongoing debate on its efficiency and safety. The ideal therapeutic agent for patent ductus arteriosus should target vascular remodelling and support the arrested molecular steps that should completely eventuate during anatomical closure.Platelet-rich plasma injection, which has been used as a treatment alternative for many musculoskeletal conditions, can be a promising solution in this context by compensating the relative platelet dysfunction in preterms and providing a convenient microenvironment for proper cellular communication for ductal closure.First, by inducing hyaluronan synthase, platelet-rich plasma can induce mount formation in the intima, which is the significant defective milestone in preterms. Second, by providing platelet-derived growth factor, it can further stimulate platelet agregation and occlusion of the lumen. Finally, it can provide an increment in local vascular endothelial growth factor and transforming growth factor-β levels, which cannot be achieved because of insufficient intramural hypoxia. Migration of the vascular smooth muscles would further be triggered by transforming growth factor-β and vascular endothelial growth factor, aiding a major contribution to ductal closure.Above and beyond all other considerations, opportunity of local application would render maximum effectiveness and minimum side effects.
Miliaria, which is extravasation of sweat into the epidermis and dermis due to sweat duct obstruction, is a commonly seen dermatologic disorder in newborns. We present a case of extensive, widespread miliaria crystallina that developed in a newborn during treatment of severe hypernatremic dehydration. A possible mechanism could be the destruction of sweat ducts with excretion of sweat with high levels of sodium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
