RESUMEN
BACKGROUND: Submersion injuries are a leading cause of injury death in children in the United States. The clinical course of a submersion patient varies depending on the presence of anoxic brain injury and acute respiratory failure. OBJECTIVE: We studied changes in clinical findings and chest radiograph findings and determined the sensitivity/specificity of the presenting chest radiograph in predicting clinical improvement within the first 24 h in pediatric submersion cases. MATERIALS AND METHODS: We conducted a cross-sectional study of pediatric submersion patients through age 18 years treated at a children's hospital from 2010 to 2013. We reviewed demographics, comorbidities, prehospital/hospital course and chest radiographic findings. Clinical improvement occurred when a child demonstrated normal vital signs and mentation. We compared radiographic findings among children based on clinical improvement up to 24 h post submersion. Using odds ratios, we calculated associations between radiographic findings and clinical improvement. We studied the sensitivity/specificity of the presenting chest radiograph in predicting clinical improvement within 24 h. RESULTS: One hundred forty-two of 262 (54%) patients had initial chest radiographs; 41% had follow-up radiographs. The odds of an abnormal initial chest radiograph were 4 times higher in children with respiratory distress or abnormal mentation at emergency department (ED) presentation compared to children without these findings (odds ratio [OR]=4.83; 95% confidence interval [CI]=2.1-10.85; P<0.001). Improvement in radiographic findings occurred in 85% of children within 24 h. Children with an abnormal initial chest radiograph were 87% less likely to improve clinically by 24 h (P<0.001). A presenting chest radiograph that was normal or with mild pulmonary edema/atelectasis predicted clinical improvement within 24 h (sensitivity 95%, specificity 57%). CONCLUSION: Most chest radiographic findings improve in pediatric submersion patients who recover within the first 24 h. An initial chest radiograph that is normal or with mild pulmonary edema/atelectasis satisfactorily predicts clinical improvement by 24 h post submersion.

Infant tuberculosis (TB) is a rare but potentially deadly infection and difficult to diagnose, especially in infants who may present with non-specific symptoms. Here, we report a case of an United States-born term infant with community-acquired miliary TB and no confirmed TB exposure history. The patient initially presented with respiratory distress at seven weeks of life with chest radiograph showing a right lower lobe (RLL) infiltrate. After failing multiple courses of treatment for community-acquired pneumonia and developing growth faltering, the patient had imaging findings suggestive of TB infection with CNS involvement. The diagnosis of TB was confirmed by QuantiFERON and purified protein derivative (PPD). In infants who fail conventional treatment for bacterial pneumonia, the differential should be broadened to consider alternative etiologies. Additionally, brain imaging should be performed in cases of disseminated TB despite negative cerebrospinal fluid (CSF) studies since these patients are at high risk of central nervous system (CNS) involvement. Topics: Tuberculosis, pneumonia, pediatrics, growth faltering.
RESUMEN
Antenatal hydronephrosis is the most frequent urinary tract anomaly detected on prenatal ultrasonography. It occurs approximately twice as often in males as in females. Most antenatal hydronephrosis is transient with little long-term significance, and few children with antenatal hydronephrosis will have significant obstruction, develop symptoms or complications, and require surgery. Some children will be diagnosed with more serious conditions, such as posterior urethral valves. Early detection of obstructive uropathy is necessary to mitigate the potential morbidity from loss of renal function. Imaging is an integral part of screening, diagnosis, and monitoring of children with antenatal hydronephrosis. Optimal timing and appropriate use of imaging can reduce the incidence of late diagnoses and prevent renal scarring and other complications. In general, follow-up neonatal ultrasound is recommended for all cases of antenatal hydronephrosis, while further imaging, including voiding cystourethrography and nuclear scintigraphy, is recommended for moderate or severe cases, or when renal parenchymal or bladder wall abnormalities are suspected. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Acute injuries to the foot are frequently encountered in the emergency room and in general practice settings. This publication defines best practices for imaging evaluations for several variants of patients presenting with acute foot trauma. The variants include scenarios when the Ottawa rules can be evaluated, when there are exclusionary criteria, and when suspected pathology is in anatomic areas not addressed by the Ottawa rules. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios.

Pneumonia is one of the most common acute infections and the single greatest infectious cause of death in children worldwide. In uncomplicated, community-acquired pneumonia in immunocompetent patients, the diagnosis is clinical and imaging has no role. The first role of imaging is to identify complications associated with pneumonia such as pleural effusion, pulmonary abscess, and bronchopleural fistula. Radiographs are recommended for screening for these complications and ultrasound and CT are recommended for confirmation. The second role of imaging is to identify underlying anatomic conditions that may predispose patients to recurrent pneumonia. CT with intravenously administered contrast is recommended for this evaluation. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Acute appendicitis represents the most common abdominal surgical urgency/emergency in children. Imaging remains a central tool in the diagnosis of acute appendicitis and has been shown to facilitate management and decrease the rate of negative appendectomies. The initial consideration for imaging in a child with suspected acute appendicitis is based on clinical assessment, which can be facilitated with published scoring systems. The level of clinical risk (low, intermediate, high) and the clinical scenario (suspicion for complication) define the need for imaging and the optimal imaging modality. In some situations, no imaging is required, while in others ultrasound, CT, or MRI may be appropriate. This review frames the presentation of suspected acute appendicitis in terms of the clinical risk and also discusses the unique situations of the equivocal or nondiagnostic initial ultrasound examination and suspected appendicitis with suspicion for complication (eg, bowel obstruction). The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Developmental dysplasia of the hip (DDH) is the most common hip pathology in infants. Although its exact pathophysiology remains incompletely understood, its long-term prognosis depends not only on the severity of the dysphasia, but also on the timely implementation of appropriate treatment. Unrecognized and untreated hip subluxations and dislocations inevitably lead to early joint degeneration while overtreatment can produce iatrogenic complications, including avascular necrosis of the femoral head. In the past two decades, imaging has become an integral part of the clinical screening, diagnosis, and monitoring of children with DDH. Optimal timing for imaging and appropriate use of imaging can reduce the incidence of late diagnoses and prevent iatrogenic complications. In general, ultrasound of the hips is recommended in infants under the age of 4 months while pelvic radiography is recommended in older infants due to the fact that the femoral head ossific nucleus typically is not formed until 4 to 6 months of age. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

PURPOSE: To describe the process by which a radiology department moved from peer review to peer collaborative improvement (PCI) and review data from the first 16 months of the PCI process. MATERIALS AND METHODS: Data from the first 16 months after PCI were reviewed: number of case reviews performed, number of learning opportunities identified, percentage yield of learning opportunities identified, type of learning opportunities identified, and comparison of the previous parameters between case randomly reviewed versus actively pushed (issues actively identified and entered). Changes in actively pushed cases were also assessed as volume per month over the 16 months (run chart). Faculty members were surveyed about their perception of the conversion to PCI. RESULTS: In all, 12,197 cases were peer reviewed, yielding 1,140 learning opportunities (9.34%). The most common types of learning opportunities for all reviewed cases included perception (5.1%) and reporting (1.9%). The yield of learning opportunities from actively pushed cases was 96.3% compared with 3.88% for randomly reviewed cases. The number of actively pushed cases per month increased over the course of the period and established two new confidence intervals. The faculty survey revealed that the faculty perceived the new PCI process as positive, nonpunitive, and focused on improvement. CONCLUSIONS: The study demonstrates that a switch to PCI is perceived as nonpunitive and associated with increased radiologist submission of learning opportunities. Active entering of identified learning opportunities had a greater yield and perceived value, compared with random review of cases.

Hematuria is the presence of red blood cells in the urine, either visible to the eye (macroscopic hematuria) or as viewed under the microscope (microscopic hematuria). The clinical evaluation of children and adolescents with any form of hematuria begins with a meticulous history and thorough evaluation of the urine. The need for imaging evaluation depends on the clinical scenario in which hematuria presents, including the suspected etiology. Ultrasound and CT are the most common imaging methods used to assess hematuria in children, although other imaging modalities may be appropriate in certain instances. This review focuses on the following clinical variations of childhood hematuria: isolated hematuria (nonpainful, nontraumatic, and microscopic versus macroscopic), painful hematuria (ie, suspected nephrolithiasis or urolithiasis), and renal trauma with hematuria (microscopic versus macroscopic). The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Imaging plays in important role in the evaluation of the acutely limping child. The decision-making process about initial imaging must consider the level of suspicion for infection and whether symptoms can be localized. The appropriateness of specific imaging examinations in the acutely limping child to age 5 years is discussed with attention in each clinical scenario to the role of radiography, ultrasound, nuclear medicine, computed tomography, and magnetic resonance imaging. Common causes of limping such as toddler's fracture, septic arthritis, transient synovitis, and osteomyelitis are discussed. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Urinary tract infection (UTI) is common in young children and may cause pyelonephritis and renal scarring. Long-term complications from renal scarring are low. The role of imaging is to evaluate for underlying urologic abnormalities and guide treatment. In neonates there is increased risk for underlying urologic abnormalities. Evaluation for vesicoureteral reflux (VUR) may be appropriate especially in boys because of higher prevalence of VUR and to exclude posterior urethral valve. In children older than 2 months with first episode of uncomplicated UTI, there is no clear benefit of prophylactic antibiotic. Ultrasound is the only study that is usually appropriate. After the age of 6 years, UTIs are infrequent. There is no need for routine imaging as VUR is less common. In children with recurrent or complicated UTI, in addition to ultrasound, imaging of VUR is usually appropriate. Renal cortical scintigraphy may be appropriate in children with VUR, as renal scarring may support surgical intervention. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

A 5-week-old female infant with vertical HIV-1 exposure, progressive cough, and failure to thrive was given a diagnosis of bilateral diffuse nodular lung lesions. The child was without fever, leukocytosis, anemia, peripheral adenopathy, or hepatosplenomegaly, and the results of repeated blood tests for HIV-1 DNA were negative. A needle biopsy of the lungs revealed granulomatous inflammation and giant cells, with fungal organisms suggestive of Aspergillus species. A nitroblue tetrazolium dye test performed on the patient's blood specimen demonstrated absence of dye reduction, suggesting a diagnosis of chronic granulomatous disease. Further analysis revealed that the child had a deficiency of the p47(phox) component of the nicotinamide adenine dinucleotide phosphate oxidase system. Thus this child with vertical HIV-1 exposure and diffuse pulmonary nodules actually had an autosomal recessive form of chronic granulomatous disease. This case study clearly demonstrates that children with suspected HIV-1 infection might also need evaluation for primary immunodeficiency and that the clinical immunology laboratory is a powerful adjunct in coming to a correct diagnosis.
