The value of posttraumatic anosmia as a predictor of late social outcomes was examined in a sample of closed head injury (CHI) patients. Unemployment rates were equally high in both the anosmic and nonanosmic closed head injury patients. ⋯ Anosmic patients had longer initial hospital stays and deeper initial comatose/confusional states. Anosmia does not appear to add incrementally to disability status and it does not automatically imply the presence of basal-frontal damage.

Mood and anxiety disorders following pediatric traumatic brain injury: a prospective study.
Studies utilizing standardized instruments for assessing mood and/or anxiety disorders following pediatric traumatic brain injury have seldom been reported in the literature. Previous reports have largely focused on cognitive impairment, behavioral dysfunction, or adaptive functioning, and have typically relied on parental informants. In this study, children hospitalized for mild (N = 42) and moderate/severe (N = 19) brain injury were assessed 6-months postinjury using the Anxiety disorders Module A and the Mood disorders Module C of the Diagnostic Interview Schedule for Children - IV Revision (DISC-IV). ⋯ Multivariate analysis demonstrated that postinjury level of stress and severity of brain injury were the most robust predictors of NOD, accounting for 23% of the variance in the model. These results support the premise that the development of a mood and/or anxiety disorder following pediatric head injury is mediated by multiple determinants. The findings suggest that early psychosocial assessment and interventions aimed at increasing a child's coping may attenuate the emotional consequences of pediatric brain injury.

The role of neuroimaging in the diagnosis and management of mild traumatic brain injury (TBI) is evolving. In general, the structural imaging techniques play a role in acute diagnosis and management, while the functional imaging techniques show promise for clarification of pathophysiology, symptom genesis, and mechanisms of recovery. ⋯ It is, therefore, important to be aware of the advantages and limitations of the various available imaging modalities. This paper selectively reviews the pertinent literature on the structural and functional imaging in mild TBI.

Comment"Damn the precision, full speed ahead with the clinical interpretation.".
The purpose of this report is to respond to Dr. Cicchetti's (1999) challenge of the minimum of 400 subjects suggested by Charter (1999) for split-half, coefficient alpha, retest, alternate-forms, validity, and inter-rater reliability coefficients.

Anterograde and retrograde memory in children anesthetized with propofol.
Prior to anesthesia with propofol for gastrointestinal endoscopy, sets of pictures were presented to 20 children and adolescents (M age = 12 years). Word pairs (e.g., "hiking-woods") were presented via earphones after the children were anesthetized. Upon regaining consciousness, the children were tested for explicit memory of both the picture sets and word pairs by free recall, cued recall, and yes/no recognition. ⋯ Postoperative testing revealed retrograde memory for material presented preoperatively but total amnesia for material presented intraoperatively. There was no evidence of implicit memory for material not available explicitly. The finding of uninterrupted ability to retain and retrieve information presented prior to anesthesia despite total anterograde amnesia has implications for preoperative communication directed toward pediatric patients as well as for intraoperative communication among surgical staff.
