Study objective We derive a prediction rule to identify children at very low risk for intra-abdominal injuries undergoing acute intervention and for whom computed tomography (CT) could be obviated. ...Methods We prospectively enrolled children with blunt torso trauma in 20 emergency departments. We used binary recursive partitioning to create a prediction rule to identify children at very low risk of intra-abdominal injuries undergoing acute intervention (therapeutic laparotomy, angiographic embolization, blood transfusion for abdominal hemorrhage, or intravenous fluid for ≥2 nights for pancreatic/gastrointestinal injuries). We considered only historical and physical examination variables with acceptable interrater reliability. Results We enrolled 12,044 children with a median age of 11.1 years (interquartile range 5.8, 15.1 years). Of the 761 (6.3%) children with intra-abdominal injuries, 203 (26.7%) received acute interventions. The prediction rule consisted of (in descending order of importance) no evidence of abdominal wall trauma or seat belt sign, Glasgow Coma Scale score greater than 13, no abdominal tenderness, no evidence of thoracic wall trauma, no complaints of abdominal pain, no decreased breath sounds, and no vomiting. The rule had a negative predictive value of 5,028 of 5,034 (99.9%; 95% confidence interval CI 99.7% to 100%), sensitivity of 197 of 203 (97%; 95% CI 94% to 99%), specificity of 5,028 of 11,841 (42.5%; 95% CI 41.6% to 43.4%), and negative likelihood ratio of 0.07 (95% CI 0.03 to 0.15). Conclusion A prediction rule consisting of 7 patient history and physical examination findings, and without laboratory or ultrasonographic information, identifies children with blunt torso trauma who are at very low risk for intra-abdominal injury undergoing acute intervention. These findings require external validation before implementation.
Background An urgent need exists in the United States to establish treatment goals in psoriasis. Objective We aim to establish defined treatment targets toward which clinicians and patients with ...psoriasis can strive to inform treatment decisions, reduce disease burden, and improve outcomes in practice. Methods The National Psoriasis Foundation conducted a consensus-building study among psoriasis experts using the Delphi method. The process consisted of: (1) literature review, (2) pre-Delphi question selection and input from general dermatologists and patients, and (3) 4 Delphi rounds. Results A total of 25 psoriasis experts participated in the Delphi process. The most preferred instrument was body surface area (BSA). The most preferred time for evaluating patient response after starting new therapies was at 3 months. The acceptable response at 3 months postinitiation was either BSA 3% or less or BSA improvement 75% or more from baseline. The target response at 3 months postinitiation was BSA 1% or less. During the maintenance period, evaluation every 6 months was most preferred. The target response at every 6 months maintenance evaluation is BSA 1% or less. Limitations Although BSA is feasible in practice, it does not encompass health-related quality of life, costs, and risks of side effects. Conclusion With defined treatment targets, clinicians and patients can regularly evaluate treatment responses and perform benefit-risk assessments of therapeutic options individualized to the patient.
Study objective We compare test characteristics of abdominal computed tomography (CT) with and without oral contrast for identifying intra-abdominal injuries. Methods This was a planned subanalysis ...of a prospective, multicenter study of children (<18 years) with blunt torso trauma. Children imaged in the emergency department with abdominal CT using intravenous contrast were eligible. Oral contrast use was based on the participating centers’ guidelines and discretions. Clinical courses were followed to identify patients with intra-abdominal injuries. Abdominal CTs were considered positive for intra-abdominal injury if a specific intra-abdominal injury was identified and considered abnormal if any findings suggestive of intra-abdominal injury were identified on the CT. Results A total of 12,044 patients were enrolled, with 5,276 undergoing abdominal CT with intravenous contrast. Of the 4,987 CTs (95%) with documented use or nonuse of oral contrast, 1,010 (20%) were with and 3,977 (80%) were without oral contrast; 686 patients (14%) had intra-abdominal injuries, including 127 CTs (19%) with and 559 (81%) without oral contrast. The sensitivity in the detection of any intra-abdominal injury in the oral contrast versus no oral contrast groups was sensitivitycontrast 99.2% (95% confidence interval CI 95.7% to 100.0%) versus sensitivityno contrast 97.7% (95% CI 96.1% to 98.8%), difference 1.5% (95% CI –0.4% to 3.5%). The specificity of the oral contrast versus no oral contrast groups was specificitycontrast 84.7% (95% CI 82.2% to 87.0%) versus specificityno contrast 80.8% (95% CI 79.4% to 82.1%), difference 4.0% (95% CI 1.3% to 6.7%). Conclusion Oral contrast is still used in a substantial portion of children undergoing abdominal CT after blunt torso trauma. With the exception of a slightly better specificity, test characteristics for detecting intra-abdominal injury were similar between CT with and without oral contrast.

Background Seasonal influenza is responsible for more than 200,000 hospitalizations each year in the United States. Although hospital-onset (HO) influenza contributes to morbidity and mortality among ...these patients, little is known about its overall epidemiology. Objective We describe patients with HO influenza in the United States during the 2010-2011 influenza season and compare them with community-onset (CO) cases to better understand factors associated with illness. Methods We identified laboratory-confirmed, influenza-related hospitalizations using the Influenza Hospitalization Surveillance Network (FluSurv-NET), a network that conducts population-based surveillance in 16 states. CO cases had laboratory confirmation ≤ 3 days after hospital admission; HO cases had laboratory confirmation > 3 days after admission. Results We identified 172 (2.8%) HO cases among a total of 6,171 influenza-positive hospitalizations. HO and CO cases did not differ by age ( P = .22), sex ( P = .29), or race ( P = .25). Chronic medical conditions were more common in HO cases (89%) compared with CO cases (78%) ( P < .01), and a greater proportion of HO cases (42%) than CO cases (17%) were admitted to the intensive care unit ( P < .01). The median length of stay after influenza diagnosis of HO cases (7.5 days) was greater than that of CO cases (3 days) ( P < .01). Conclusion HO cases had greater length of stay and were more likely to be admitted to the intensive care unit or die compared with CO cases. HO influenza may play a role in the clinical outcome of hospitalized patients, particularly among those with chronic medical conditions.
Abstract Context Peripheral neuropathy is one of the most common complications of diabetes. Objectives The purpose of this study was to evaluate the effects of photon stimulation on pain intensity, ...pain relief, pain qualities, sensation and quality of life (QOL) in patients with painful diabetic peripheral neuropathy. Methods In this randomized, placebo-controlled trial, patients were assigned to receive either four photon stimulations ( n = 63) or four placebo ( n = 58) treatments. Pain intensity, pain relief, and pain qualities were assessed using self-report questionnaires. Sensation was evaluated using monofilament testing. QOL was measured using the Medical Outcomes Study Short Form-36 (SF-36). Multilevel regression model analyses were used to evaluate between-group differences in study outcomes. Results No differences, over time, in any pain intensity scores (i.e., pain intensity immediately post-treatment, average pain, worst pain) or pain relief scores were found between the placebo and treatment groups. However, significant decreases, over time, were found in some pain quality scores, and significant improvements in sensation were found in patients who received the photon stimulation compared with placebo. In addition, patients in the treatment group reported significant improvements in SF-36 social functioning and mental health scores. Findings from a responder analysis demonstrated that no differences were found in the percentages of patients in the placebo and treatment groups who received 30% or more or 50% or more reduction in pain scores immediately post-treatment. However, significant differences were found in the distribution of the changes in pain relief scores, with most of the patients in the photon stimulation group reporting a slight (28.6%) to moderate (34.9%) improvement in pain relief from the beginning to the end of the study compared with no change in pain relief (43.1%) in the placebo group. Conclusion Four treatments with photon stimulation resulted in significant improvements in some pain qualities, sensation, and QOL outcomes in a sample of patients with a significant amount of pain and disability from their diabetes. A longer duration study is needed to further refine the photon stimulation treatment protocol in these chronically ill patients and to evaluate the sustainability of its effects.
