The prevalence of diabetic ketoacidosis (DKA) in children with type 1 diabetes mellitus (T1DM) is 30% at the time of diagnosis.1 Cerebral edema is a rare, but life-threatening complication of DKA, ...occurring in only 0.3 - 1% of cases.2 Deep vein thrombosis and acute pancreatitis are other rare complications of DKA. Supraventricular tachycardia (SVT) as a complication of pediatric DKA has been reported.3 A unique case of a pediatric patient who had multiple rare complications of DKA including cerebral edema, venous thrombosis, and hypertriglyceridemia associated acute pancreatitis is presented.The SVT episode encountered during the admission was due to complications arising from a procedure and not due to DKA itself.
To characterize racial and ethnic disparities in the evaluation and reporting of suspected abusive head trauma (AHT) across the 18 participating sites of the Pediatric Brain Injury Research Network ...(PediBIRN). We hypothesized that such disparities would be confirmed at multiple sites and occur more frequently in patients with a lower risk for AHT.
Aggregate and site-specific analysis of the cross-sectional PediBIRN dataset, comparing AHT evaluation and reporting frequencies in subpopulations of white/non-Hispanic and minority race/ethnicity patients with lower vs higher risk for AHT.
In the PediBIRN study sample of 500 young, acutely head-injured patients hospitalized for intensive care, minority race/ethnicity patients (n = 229) were more frequently evaluated (P < .001; aOR, 2.2) and reported (P = .001; aOR, 1.9) for suspected AHT than white/non-Hispanic patients (n = 271). These disparities occurred almost exclusively in lower risk patients, including those ultimately categorized as non-AHT (P = .001 aOR, 2.4 and P = .003 aOR, 2.1) or with an estimated AHT probability of ≤25% (P < .001 aOR, 4.1 and P < .001 aOR, 2.8). Similar site-specific analyses revealed that these results reflected more extreme disparities at only 2 of 18 sites, and were not explained by local confounders.
Significant race/ethnicity-based disparities in AHT evaluation and reporting were observed at only 2 of 18 sites and occurred almost exclusively in lower risk patients. In the absence of local confounders, these disparities likely represent the impact of local physicians' implicit bias.
Data guiding abusive head trauma (AHT) diagnosis rest on case-control studies that have been criticized for circularity. We wished to sort children with neurologic injury using mathematical ...algorithms, without reference to physicians' diagnoses or predetermined diagnostic criteria, and to compare the results to existing AHT data, physicians' diagnoses, and a proposed triad of findings.
Unsupervised cluster analysis of an existing data set regarding 500 young patients with acute head injury hospitalized for intensive care. Three cluster algorithms were used to sort (partition) patients into subpopulations (clusters) on the basis of 32 reliable (κ > 0.6) clinical and radiologic variables. P values and odds ratios (ORs) identified variables most predictive of partitioning.
The full cohort partitioned into 2 clusters. Variables substantially (P < .001 and OR > 10 in all 3 cluster algorithms) more prevalent in cluster 1 were imaging indications of brain hypoxemia, ischemia, and/or swelling; acute encephalopathy, particularly when lasting >24 hours; respiratory compromise; subdural hemorrhage or fluid collection; and ophthalmologist-confirmed retinoschisis. Variables substantially (P < .001 and OR < 0.10 in any cluster algorithm) more prevalent in cluster 2 were linear parietal skull fracture and epidural hematoma. Postpartitioning analysis revealed that cluster 1 had a high prevalence of physician-diagnosed abuse.
Three cluster algorithms partitioned the population into 2 clusters without reference to predetermined diagnostic criteria or clinical opinion about the nature of AHT. Clinical difference between clusters replicated differences previously described in comparisons of AHT with non-AHT. Algorithmic partition was predictive of physician diagnosis and of the triad of findings heavily discussed in AHT literature.
Evidence-based, patient-specific estimates of abusive head trauma probability can inform physicians’ decisions to evaluate, confirm, exclude, and/or report suspected child abuse.
To derive a clinical ...prediction rule for pediatric abusive head trauma that incorporates the (positive or negative) predictive contributions of patients’ completed skeletal surveys and retinal exams.
500 acutely head-injured children under three years of age hospitalized for intensive care at one of 18 sites between 2010 and 2013.
Secondary analysis of an existing, cross-sectional, prospective dataset, including (1) multivariable logistic regression to impute the results of abuse evaluations never ordered or completed, (2) regularized logistic regression to derive a novel clinical prediction rule that incorporates the results of completed abuse evaluations, and (3) application of the new prediction rule to calculate patient-specific estimates of abusive head trauma probability for observed combinations of its predictor variables.
Applying a mean probability threshold of >0.5 to classify patients as abused, the 7-variable clinical prediction rule derived in this study demonstrated sensitivity 0.73 (95% CI: 0.66-0.79) and specificity 0.87 (95% CI: 0.82-0.90). The area under the receiver operating characteristics curve was 0.88 (95% CI: 0.85-0.92). Patient-specific estimates of abusive head trauma probability for 72 observed combinations of its seven predictor variables ranged from 0.04 (95% CI: 0.02-0.08) to 0.98 (95% CI: 0.96-0.99).
Seven variables facilitate patient-specific estimation of abusive head trauma probability after abuse evaluation in intensive care settings.
To replicate the previously published finding that the absence of a history of trauma in a child with obvious traumatic head injuries demonstrates high specificity and high positive predictive value ...(PPV) for abusive head trauma.
This was a secondary analysis of a deidentified, cross-sectional dataset containing prospective data on 346 young children with acute head injury hospitalized for intensive care across 18 sites between 2010 and 2013, to estimate the diagnostic relevance of a caregiver's specific denial of any trauma, changing history of accidental trauma, or history of accidental trauma inconsistent with the child's gross motor skills. Cases were categorized as definite or not definite abusive head trauma based solely on patients' clinical and radiologic findings. For each presumptive historical “red flag,” we calculated sensitivity, specificity, predictive values, and likelihood ratio (LR) with 95% CI for definite abusive head trauma in all patients and also in cohorts with normal, abnormal, or persistent abnormal neurologic status.
A caregiver's specific denial of any trauma demonstrated a specificity of 0.90 (95% CI, 0.84-0.94), PPV of 0.81 (95% CI, 0.71-0.88), and a positive LR (LR+) of 4.83 (95% CI, 3.07-7.61) for definite abusive head trauma in all patients. Specificity and LR+ were lowest—not highest—in patients with persistent neurologic abnormalities. The 2 other historical red flags showed similar trends.
A caregiver's specific denial of any trauma, changing history of accidental trauma, or history of accidental trauma that is developmentally inconsistent are each highly specific (>0.90) but may provide weaker support than previously reported for a diagnosis of abusive head trauma in patients with persistent neurologic abnormalities.
Rat bite fever is a rare infection typically caused by Streptobacillus moniliformis. The mode of transmission is most commonly through a bite or scratch from an infected rat. This disease is ...characterized by polyarthritis, fever, and a delayed onset erythematous maculopapular rash of the extremities. The authors report a case of rat bite fever, which led to septic arthritis of the hip. To the authors' knowledge, the complication of hip sepsis requiring an arthrotomy has not been reported in the literature. The orthopaedist should be aware of not only Streptobacillus moniliformis, but also of other zoonotic organisms, which potentially can cause septic arthritis and warrant treatment with specific antibiotics.
