Assessment of the Wisconsin Criteria at a Level I Trauma Center.

ABSTRACT: The Wisconsin Criteria was developed for physicians evaluating facial trauma to determine the likelihood of facial fractures. Subsequent studies have not consistently validated these criteria. This study seeks to validate the Wisconsin Criteria and determine its utility in predicting operative facial fractures.Retrospective chart review of the trauma database registry at a Level I Trauma Center was conducted from September 2011 to May 2019. Adult patients who had a complete facial examination by otolaryngology or plastic surgery as well as a head computed tomography scan completed, were included. Fisher exact test was utilized for statistical analysis ( P < 0.05) and positive predictive value, and negative predictive value (NPV) were calculated with a 95% confidence interval.After screening, 546 patients met eligibility, 448 had at least 1 finding of the Wisconsin Criteria, and 472 patients had facial fractures. The sensitivity of the Wisconsin Criteria for determining the presence of a facial fracture was 86.23%, the specificity was 44.59%, and the NPV was 33.67% ( P < .0001). Malocclusion was the criterion most specific in determining if a facial fracture was present (98.65%), and Glasgow Coma Score < 14 was the least specific (67.57%).The Wisconsin Criteria did aid in the identification of facial fractures in trauma patients with a comparable sensitivity, higher specificity, and much lower NPV than originally described. Further investigation should be done to validate the criteria in other large trauma centers.

Variations in Postoperative Management of Pediatric Open-Vault Craniosynostosis.

ABSTRACT: Craniosynostosis is the premature fusion of 1 or more of the calvarial sutures causing a secondary distortion of the skull shape due to lack of growth perpendicular to the fused suture and compensatory overgrowth parallel to the suture. Open vault craniosynostosis repair requires extensive dissection and reshaping of the skull and can be associated with significant pain, commonly undervalued, and underreported in the pediatric cohort. Although there is an extensive body of literature focusing on the operative treatment of craniosynostosis, there is little consensus about optimal postoperative management protocols, including pain control regimens. The purpose of this study was to assess variation in immediate postoperative management protocols within the United States. A Qualtrics-based survey was submitted to all 112 American Cleft Palate-Craniofacial Association-approved craniofacial teams regarding their routine postoperative management protocol. Nineteen responses were obtained. All surgeons reported routine post-op intensive care unit stay. Mean overall length of stay was 3.5 days. Pain control agents included acetaminophen (100%), intravenous opioids (95%), oral opioids (79%), and ketorolac (53%). Eighty-eight percent of surgeons reported utilizing vital signs and observational parameters for pain assessment with 47% reporting the use of a formal pain scale. Sixty-three percent of those surveyed used a drain, 88% used a foley catheter, 75% used postoperative prophylactic antibiotics, and 75% routinely used arterial line monitoring postoperatively. The results of this survey will be the basis for future direction in understanding the efficacy of differing management protocols and further study of pain management in the pediatric craniosynostosis population.

Can You Trust What You Watch? An Assessment of the Quality of Information in Aesthetic Surgery Videos on YouTube.

BACKGROUND: Videos on YouTube can be posted without regulation or content oversight. Unfortunately, many patients use YouTube as a resource on aesthetic surgery, leading to misinformation. Currently, there are no objective assessments of the quality of information on YouTube about aesthetic surgery. METHODS: YouTube was queried for videos about the 12 most common aesthetic surgical procedures, identified from the 2015 American Society of Plastic Surgeons procedural statistics between May and June of 2016. The top 25 results for each search term were scored using the modified Ensuring Quality Information for Patients criteria based on video structure, content, and author identification. Average Ensuring Quality Information for Patients score, view count, and video duration were compared between authorship groups. RESULTS: A total of 523 videos were graded after excluding duplicates. The mean modified Ensuring Quality Information for Patients score for all videos was 13.1 (SE, 0.18) of a possible 27. The videos under the search "nose reshaping" had the lowest mean score of 10.24 (SE, 0.74), whereas "breast augmentation" had the highest score of 15.96 (SE, 0.65). Physician authorship accounted for 59 percent of included videos and had a higher mean Ensuring Quality Information for Patients score than those by patients. Only three of the 21 search terms had a mean modified Ensuring Quality Information for Patients score meeting criteria for high-quality videos. CONCLUSIONS: The information contained in aesthetic surgery videos on YouTube is low quality. Patients should be aware that the information has the potential to be inaccurate. Plastic surgeons should be encouraged to develop high-quality videos to educate patients.

Hyperphosphorylated tau is elevated in Alzheimer's disease with psychosis.

Psychosis occurs in 40-60% of Alzheimer's disease (AD) subjects, is heritable, and indicates a more rapidly progressive disease phenotype. Neuroimaging and postmortem evidence support an exaggerated prefrontal cortical synaptic deficit in AD with psychosis. Microtubule-associated protein tau is a key mediator of amyloid-ß-induced synaptotoxicity in AD, and differential mechanisms of progressive intraneuronal phospho-tau accumulation and interneuronal spread of tau aggregates have recently been described. We hypothesized that psychosis in AD would be associated with greater intraneuronal concentration of phospho-tau and greater spread of tau aggregates in prefrontal cortex. We therefore evaluated prefrontal cortex phospho-tau in a cohort of 45 AD cases with and without psychosis. Intraneuronal phospho-tau concentration was higher in subjects with psychosis, while a measure of phospho-tau spread, volume fraction, was not. Across groups both measures were associated with lower scores on the Mini-Mental State Examination and Digit Span Backwards test. These novel findings indicate that tau phosphorylation may be accelerated in AD with psychosis, indicating a more dynamic, exaggerated pathology in AD with psychosis.

ß-Amyloid 42/40 ratio and kalirin expression in Alzheimer disease with psychosis.

Psychosis in Alzheimer disease differentiates a subgroup with more rapid decline, is heritable, and aggregates within families, suggesting a distinct neurobiology. Evidence indicates that greater impairments of cerebral cortical synapses, particularly in dorsolateral prefrontal cortex, may contribute to the pathogenesis of psychosis in Alzheimer disease (AD) phenotype. Soluble ß-amyloid induces loss of dendritic spine synapses through impairment of long-term potentiation. In contrast, the Rho guanine nucleotide exchange factor (GEF) kalirin is an essential mediator of spine maintenance and growth in cerebral cortex. We therefore hypothesized that psychosis in AD would be associated with increased soluble ß-amyloid and reduced expression of kalirin in the cortex. We tested this hypothesis in postmortem cortical gray matter extracts from 52 AD subjects with and without psychosis. In subjects with psychosis, the ß-amyloid(1-42)/ß-amyloid(1-40) ratio was increased, due primarily to reduced soluble ß-amyloid(1-40), and kalirin-7, -9, and -12 were reduced. These findings suggest that increased cortical ß-amyloid(1-42)/ß-amyloid(1-40) ratio and decreased kalirin expression may both contribute to the pathogenesis of psychosis in AD.
