Retropharyngeal abscess is a deep neck space infection that may present in various subtle ways permitting potentially lethal complications to occur before appropriate diagnosis is made and expedient management undertaken. This article reviews in detail the pertinent anatomy, diagnostic pearls, and clinical recommendations to optimally manage these common infections in children. © 2012 Bentham Science Publishers.

There is concern at the National Heart, Lung, and Blood Institute (NHLBI) and among transfusion medicine specialists regarding the small number of investigators and studies in the field of pediatric transfusion medicine (PTM). Accordingly, the objective of this article is to provide a snapshot of the clinical and translational PTM research considered to be of high priority by pediatricians, neonatologists, and transfusion medicine specialists. Included is a targeted review of three research areas of importance: (i) transfusion strategies, (ii) short- and long-term clinical consequences, and (iii) transfusion-transmitted infectious diseases. The recommendations by PTM and transfusion medicine specialists represent opportunities and innovative strategies to execute translational research, observational studies, and clinical trials of high relevance to PTM. With the explosion of new biomedical knowledge and increasingly sophisticated methodologies over the past decade, this is an exciting time to consider transfusion medicine as a paradigm for addressing questions related to fields such as cell biology, immunology, neurodevelopment, outcomes research, and many others. Increased awareness of PTM as an important, fertile field and the promotion of accompanying opportunities will help establish PTM as a viable career option and advance basic and clinical investigation to improve the health and wellbeing of children.

Neurologic complications are frequently encountered in dialysis patients. These may be due to the uremic state or to dialysis therapy, and require careful assessment. With longer survival of dialysis patients, these neurologic complications may significantly affect morbidity, mortality, and patients' well-being.Central nervous system involvement includes uremic encephalopathy as well as dialysis disequilibrium disorder. Both are rarely seen because of current improved understanding of their pathogenesis and treatment. Manifestations of atherosclerosis, stroke, and other neuropathies are present in this population and are not significantly altered by dialysis therapy. In recent years, increasing numbers of sleep disorders are being recognized. Peripheral nervous system involvement is also noted, including myopathy and related categories.In this chapter, we address clinical and pathophysiologic aspects of nervous system disorders in dialysis patients while discussing available therapeutic options to address the neurologic involvement. © 2014 Elsevier B.V.

Objective:Inhaled nitric oxide (iNO) is a potential new therapy for prevention of bronchopulmonary dysplasia and brain injury in premature infants. This study examined dose-related effects of iNO on NO metabolites as evidence of NO delivery.Study Design:A subset of 102 premature infants in the NO CLD trial, receiving 24 days of iNO (20 p.p.m. decreasing to 2 p.p.m.) or placebo, were analyzed. Tracheal aspirate (TA) and plasma samples collected at enrollment and at intervals during study gas were analyzed for NO metabolites.Result:iNO treatment increased NO metabolites in TA at 20 and 10 p.p.m. (1.7- to 2.3-fold vs control) and in plasma at 20, 10, and 5 p.p.m. (1.6- to 2.3-fold). In post hoc analysis, treated infants with lower metabolite levels at entry had an improved clinical outcome.Conclusion:iNO causes dose-related increases in NO metabolites in the circulation as well as lung fluid, as evidenced by TA analysis, showing NO delivery to these compartments. © 2010 Nature Publishing Group.

OBJECTIVE: The goal was to measure differences in the causes, mechanisms, acute clinical presentations, injuries, and outcomes of children <36 months of age with varying "greatest depths" of acute cranial injury. METHODS: Children <36 months of age who were hospitalized with acute head trauma were recruited at multiple sites. Clinical and imaging data were collected, and caregivers underwent scripted interviews. Neurodevelopmental evaluations were completed 6 months after injury. Head trauma causes were categorized independently, and subject groups with varying greatest depths of injury were compared. RESULTS: Fifty-four subjects were enrolled at 9 sites. Twenty-seven subjects underwent follow-up neurodevelopmental assessments 6 months after injury. Greatest depth of visible injury was categorized as scalp, skull, or epidural for 20 subjects, subarachnoid or subdural for 13, cortical for 10, and subcortical for 11. Compared with subjects with more-superficial injuries, subjects with subcortical injuries more frequently had been abused (odds ratio [OR]: 35.6; P < .001), more frequently demonstrated inertial injuries (P < .001), more frequently manifested acute respiratory (OR: 43.9; P < .001) and/or circulatory (OR: 60.0; P< .001) compromise, acute encephalopathy (OR: 28.5; P = .003), prolonged impairments of consciousness (OR: 8.4; P = .002), interhemispheric subdural hemorrhage (OR: 10.1; P= .019), and bilateral brain hypoxia, ischemia, or swelling (OR: 241.6; P<.001), and had lower Mental Developmental Index (P= .006) and Gross Motor Quotient (P < .001) scores 6 months after injury. CONCLUSION: For children <3 years of age, head injury depth is a useful indicator of injury causes and mechanisms.
