Characteristic features of inflicted TBI included acute computed tomography/magnetic resonance imaging findings of preexisting brain injury, extraaxial hemorrhages, seizures, retinal hemorrhages, and significantly impaired cognitive function without prolonged impairment of consciousness.

Acute CT/MRI findings were examined in a prospective, longitudinal study of 60 children 0-6 years of age hospitalized for moderate to severe traumatic brain injury (TBI). TBI was categorized as either inflicted (n = 31) or noninflicted (n = 29). Glasgow Coma Scale scores and perinatal history were comparable in both groups. Acute CT/MRI studies were visually inspected by a radiologist blind to group membership. Compared with the noninflicted TBI group, the inflicted TBI group had significantly elevated rates of subdural interhemispheric and convexity hemorrhages as well as signs of pre-existing brain abnormality, including cerebral atrophy, subdural hygroma, and ex vacuo ventriculomegaly. Intraparenchymal hemorrhage, shear injury, and skull fractures were more frequent after non-inflicted TBI. Subarachnoid hemorrhage and infarct/edema occurred with comparable frequency in both groups. Characteristic acute neuroimaging findings of inflicted TBI included multiple extraaxial hemorrhages in addition to the mild atrophy, subdural hygromas, and ventriculomegaly that suggest prior brain abnormality.

CINCH (Consortium for the Immunization of Norfolk's Children) is an urban coalition that was developed in 1993 to improve childhood immunization rates in Norfolk, Virginia. CINCH involves diverse citizens and institutions in effective community-based assessment, planning, and action. A needs assessment from 1993 found that only 49% of Norfolk 2-year-olds were adequately immunized. Using this data, CINCH developed a plan focused on education and communication, support for at-risk families, increased access to immunizations, and improved immunization delivery. After federal funding ended in 1995, members voted to expand the scope of the coalition to address additional child health needs and to broaden the membership. CINCH is a model for a sustainable city-citizen learning environment that intervenes to "help families help themselves to better health." The coalition is presented as an organization that focuses on community empowerment and development. The stages of coalition development and implications for coalition implementation in other sites are discussed.

Abstract. Objective:To compare the efficacy of intravenous (IV) midazolam with that of IV pentobarbital when used for sedation for head computed tomography (CT) imaging in emergency department (ED) pediatric patients. Methods: Prospective, randomized clinical trial in an urban children's hospital. During a two-and-a-half-year period, 55 patients were enrolled: 34 males and 21 females. Measurements included induction time, recovery time, efficacy, side effects, complications, and failure with each drug. Success of sedation was graded as good (GS), adequate (AS), poor (PS), or unsuccessful (US). Results: Sedation for CT was used for patients with the following problems: head trauma (21/55), central nervous system pathology (17/55), ventriculoperitoneal shunt evaluation (6/55), periorbital cellulitis (6/55), and retropharyngeal abscess (5/55). Twenty-nine (53%) patients received pentobarbital (mean Ϯ SD dose 3.75 Ϯ 1.10 mg/kg) and 26 (47%) patients received midazolam (mean Ϯ SD dose 0.2 Ϯ 0.03 mg/ kg). In the pentobarbital group, 28 (97%) patients were scanned and successfully sedated. Pentobarbital's mean induction time was 6 minutes and duration of sedation averaged 86 minutes. In the midazolam group, only five (19%) patients were successfully scanned with midazolam alone. Of the 21 (81%) patients given midazolam who were unsuccessfully sedated, 12 (61%) were subsequently sedated with the addition of pentobarbital for completion of CT imaging. Mild oxygen desaturation, O 2 sat >90% yet <94%, was seen in only four patients. All four patients responded to blow-by oxygen and required no other intervention. Conclusion: Intravenous pentobarbital is more effective than IV midazolam for sedation of children requiring CT imaging.

We compared cerebral blood flow (CBF) estimated using transmission mode near infrared spectroscopy (NIRS) and a modification of the Fick principle with CBF quantitations by radioactive microspheres (MSs) in newborn piglets. Thirteen piglets were studied during steady state, ischemia, and during two reflow periods. NIRS and MS flows were not significantly different during any measurement period. NIRS flows were compared to total brain blood flows and to regional brain blood flows quantitated with MSs and correlated best with temporal cortical flows. Linear regression analysis of the NIRS flows plotted against MS-quantitated temporal cortical flows showed r = 0.71. Thus, CBFs obtained with NIRS were not significantly different from, showed the same directional changes, and correlated acceptably with flows quantitated by MSs.
