RESUMEN
OBJECTIVES: To identify independent predictors of and derive a risk score for acute hematogenous osteomyelitis (AHO) in children. METHODS: We conducted a retrospective matched case-control study of children >90 days to <18 years of age undergoing evaluation for a suspected musculoskeletal (MSK) infection from 2017 to 2019 at 23 pediatric emergency departments (EDs) affiliated with the Pediatric Emergency Medicine Collaborative Research Committee. Cases were identified by diagnosis codes and confirmed by chart review to meet accepted diagnostic criteria for AHO. Controls included patients who underwent laboratory and imaging tests to evaluate for a suspected MSK infection and received an alternate final diagnosis. RESULTS: We identified 1135 cases of AHO matched to 2270 controls. Multivariable logistic regression identified 10 clinical and laboratory factors independently associated with AHO. We derived a 4-point risk score for AHO using (1) duration of illness >3 days, (2) history of fever or highest ED temperature ≥38°C, (3) C-reactive protein >2.0 mg/dL, and (4) erythrocyte sedimentation rate >25 mm per hour (area under the curve: 0.892, 95% confidence interval [CI]: 0.881 to 0.901). Choosing to pursue definitive diagnostics for AHO when 3 or more factors are present maximizes diagnostic accuracy at 84% (95% CI: 82% to 85%), whereas children with 0 factors present are highly unlikely to have AHO (sensitivity: 0.99, 95% CI: 0.98 to 1.00). CONCLUSIONS: We identified 10 predictors for AHO in children undergoing evaluation for a suspected MSK infection in the pediatric ED and derived a novel 4-point risk score to guide clinical decision-making.

OBJECTIVES: Acute osteomyelitis is a challenging diagnosis to make in the pediatric emergency department (ED), in part because of variability in its presentation. There are limited data detailing the presenting features of pediatric osteomyelitis, factors that are essential to understand to inform diagnostic decision making. We sought to describe relevant clinical data that contributed to the diagnosis of acute osteomyelitis in children presenting to a pediatric ED. METHODS: This was a 10-year retrospective cohort study of patients 18 years or younger diagnosed with acute osteomyelitis in the ED of a large tertiary care children's hospital. Collected data included demographics, clinical history, patient-reported symptoms, vital signs, physical examination findings, and results of basic laboratory, microbiologic, and imaging studies. Descriptive statistics were used to summarize key findings. RESULTS: Two hundred eleven cases of acute osteomyelitis were identified during the study period. The median age was 8.4 years, with 61.1% male. One hundred twenty-seven patients (60.2%) presented to care more than once before being diagnosed. Common symptoms included pain (94.3%), functional limitation (83.9%), and fever (76.3%). Common examination findings included functional limitation (78.2%), focal tenderness (73.5%), and swelling (52.1%). One hundred seventeen patients (55.5%) were febrile during their ED evaluation. Elevated C-reactive protein (>0.8 mg/dL, 92.9%) and erythrocyte sedimentation rate (>10 mm/h, 94.3%) were the most sensitive laboratory markers. CONCLUSIONS: Fever may be absent in up to a quarter of pediatric patients with acute osteomyelitis. Although highly sensitive, inflammatory marker elevations were more modest than those reported previously in cases of pediatric septic arthritis.

ABSTRACT: Delayed subaponeurotic fluid collections (DSFCs) are a recently described cause of idiopathic scalp swelling in young infants. Associated with traumatic birth and the use of vacuum-assisted devices or fetal scalp electrodes, DSFCs can be differentiated from similar causes of neonatal scalp swelling based on characteristic history and physical examination findings. In this article, we highlight 2 cases of young infants presenting to a pediatric emergency department with large, fluctuant scalp swellings, which were appropriately diagnosed as DSFCs; clinical data on an additional eight cases are presented in table format. In cases of isolated DSFCs in otherwise well-appearing infants, further laboratory work, imaging, subspecialty consultation, and child abuse investigation is not necessary. Recommendations for the diagnosis and management of DSFCs presented reflect the clinical experience of the authors in conjunction with a review of the available medical literature on this topic.

BACKGROUND: Few studies describe medical complaints and substance use patterns related to attending music concerts. As such, the objective of this study is to describe patient demographics, substance use and intoxication patterns, and medical interventions provided to adolescents and young adults assessed in an emergency department (ED) for complaints directly related to concert attendance. METHODS: A retrospective chart review of patients 13-30 years old who were transported to the ED directly from music concerts between January 2011 and December 2015 was conducted. Descriptive statistics and logistic regression were used to analyze patient demographic, intervention, and substance use data. RESULTS: There were 115 concerts identified, of which 48 (42%) were linked to 142 relevant ED visits; the total number of attendees at each concert is unknown. The mean age of the 142 described patients was 19.5 years (SD 3.3) with 72% < 21 and 33% < 18; 71% of patients were female and 96% of visits were substance-use related. Mean blood alcohol level was 242 mg/dL (range 104-412, SD 70). Glasgow Coma Scale (GCS) scores ranged from 3 to 15, with a mean of 14. Two patients required intubation and 61% of patients received interventions, including medications (47%), intravenous fluids (46%), specialty consultation (20%), restraints (14%), imaging (6%), and laceration repair (3%). Attendance at pop and electronic dance music concerts was associated with the widest ranges of GCS scores (8-15 and 6-14 respectively), mass casualty incident declarations, and among the highest mean blood alcohol levels (246 and 244 mg/dL, respectively). CONCLUSIONS: Substance use is the predominant reason for music concert related ED visits and patients may have serious levels of intoxication, receiving multiple medical interventions. These data demonstrate the need for additional large-scale studies to confirm trends and increase awareness of this important public health problem.
