Published: May 2008

Background Stress radiography provides an objective tool to measure posterior knee instability. Intraobserver and interobserver reliability has been reported for the Telos device, but it has not been studied using the kneeling technique. Purpose This study was conducted to evaluate the intraobserver and interobserver reliability of measurements made using kneeling stress radiography to quantify posterior knee instability. Study Design Case series (diagnosis); Level of evidence, 4. Methods One hundred thirty-two stress radiographs in 44 patients with suspected posterior knee instability were prospectively taken using the kneeling technique. The amount of posterior displacement on the radiographs was then measured independently by 3 blinded testers (an orthopaedic sports medicine faculty member, an orthopaedic chief resident, and a medical student) on 2 separate occasions. Changes in mean and intraclass correlation coefficients (ICCs) were examined to assess the intraobserver and interobserver reliability of the measurements. Results Intraobserver changes in displacement means were small (−0.307 mm, −0.294 mm, and +0.035 mm) and only significant for observer 1. The combined intraobserver ICC was 0.973 for the 3 observers (0.976, 0.959, and 0.981). Interobserver comparisons revealed significant differences in trial 1 between observers 2 and 3 (0.675 mm), no differences in trial 2, and significant differences between observers 1 and 2 (0.333 mm) and observers 2 and 3 (0.510 mm) in the combined trial data. The combined interobserver ICC was 0.955 for the 3 observers (0.959 and 0.951 for the 2 trials). Conclusions The kneeling technique for posterior cruciate ligament stress radiography provides a reproducible method to quantify posterior knee instability.

OBJECTIVE. Screening examination for retinopathy of prematurity is distressing and painful. The aim of the present study was to investigate whether a Newborn Individualized Developmental Care and Assessment Program intervention during a retinopathy of prematurity examination results in less adverse behavioral, pain, and stress responses as compared with standard care.METHODS. The first 2 eye examinations in 36 preterm infants were evaluated. The infants were randomly assigned at the first eye examination to receive either Newborn Individualized Developmental Care and Assessment Program care or standard care. At the second examination, crossover of subject assignment was performed. The assessments included behavioral responses; recordings of heart rate, respiration, and oxygenation; pain scores (premature infant pain profile); and salivary cortisol at defined time points up to 4 hours after the eye examination. The nursing support given during the eye examinations (intervention score) were scored using predefined criteria.RESULTS. Altogether, 68 examinations were evaluated. Newborn Individualized Developmental Care and Assessment Program care was associated with better behavioral scores during the examination but there was no difference in heart rate, respiratory rate, oxygenation, or premature infant pain profile score between the 2 care strategies before or after the eye examination. Salivary cortisol increased from baseline to 30 minutes after the eye examination independent of care strategy and decreased significantly between 30 and 60 minutes when infants were subjected to Newborn Individualized Developmental Care and Assessment Program care but not after standard care. During the study period the intervention score for standard care increased and approached the score for Newborn Individualized Developmental Care and Assessment Program care at the later eye examinations.CONCLUSION. A Newborn Individualized Developmental Care and Assessment Program-based intervention during eye examination does not decrease pain responses but results in faster recovery, as measured by lower salivary cortisol 60 minutes after the examination. The differences were seen despite the influence from the Newborn Individualized Developmental Care and Assessment Program intervention on the standard care treatment that occurred during the study period.

OBJECTIVES. The objectives were to determine the frequency of congenital cytomegalovirus infection among newborns who did not pass hearing screening tests or had confirmed hearing loss and to determine how often abnormal hearing screening results were the only manifestation of congenital cytomegalovirus infection.METHODS. Retrospective chart review was performed for newborns who had abnormal hearing screening results and positive urine cytomegalovirus culture results at Parkland Memorial Hospital between September 1, 1999, and August 31, 2004.RESULTS. During the 5-year study period, 572 of 79047 newborns (7 of 1000 live births) did not pass hearing screening tests. Cytomegalovirus infection was identified in 24 (5%) of 483 tested infants and 16 (6%) of the 256 infants with subsequently confirmed hearing impairment. Of those 16 infants, 12 (75%) were identified as having congenital cytomegalovirus infection only because of failure to pass newborn hearing screening tests.CONCLUSIONS. Congenital cytomegalovirus infection was present for 6% of newborns with confirmed hearing impairment, and the majority of those infants were identified on the basis of abnormal newborn hearing screening results.

Published: May 2008

OBJECTIVE. The objective of this study was to present a detailed examination of unintentional injuries in infants ≤12 months of age treated in emergency departments.
METHODS. We conducted a retrospective analysis of data for infants ≤12 months of age from the National Electronic Surveillance System-All Injury Program for 2001–2004. Sample weights provided by the National Electronic Surveillance System-All Injury Program were used to make national estimates.
RESULTS. An estimated 1314000 injured infants were treated in US emergency departments for nonfatal unintentional injuries during the 4-year period of 2001–2004, ∼1 infant every 1.5 minutes. Falls were the leading cause of nonfatal unintentional injuries for infants. Overall, the patients were more likely to be male (55.2%) than female (44.8%). Contusions/abrasions were the leading diagnosis overall (26.7%). Contusion/abrasion, laceration, hematoma, foreign-body, and puncture injuries occurred most frequently to the head or neck region. More than one third of fractures (37.2%) were to the arm or hand. Bed was the product most frequently noted as being involved in the injury event for every age except 2 and 12 months (car seat was the most frequently noted product at 2 months of age, and stairs were top ranked at 12 months). Product rank changed markedly as age increased.
CONCLUSIONS. The influences of the social environment, the physical environment, and products change as infants mature in the first year of life; this was substantiated in our study by the shift in the relative importance of products involved in injuries according to month of age. The concept that aspects of safety must adapt in anticipation of developmental stage is critical.

OBJECTIVE. Our goal was to identify antepartum, intrapartum, and infant risk factors for birth asphyxia mortality in a rural, low-resource, population-based cohort in southern Nepal.
PATIENTS AND METHODS. Data were collected prospectively during a cluster-randomized, community-based trial evaluating the impact of newborn skin and umbilical cord cleansing on neonatal mortality and morbidity in Sarlahi, Nepal. A total of 23662 newborn infants were enrolled between September 2002 and January 2006. Multivariable regression modeling was performed to determine adjusted relative risk estimates of birth asphyxia mortality for antepartum, intrapartum, and infant risk factors.
RESULTS. Birth asphyxia deaths (9.7/1000.0 live births) accounted for 30% of neonatal mortality. Antepartum risk factors for birth asphyxia mortality included low paternal education, Madeshi ethnicity, and primiparity. Facility delivery; maternal fever; maternal swelling of the face, hands, or feet; and multiple births were significant intrapartum risk factors for birth asphyxia mortality. Premature infants (&lt;37 weeks) were at higher risk, and the combination of maternal fever and prematurity resulted in a 7-fold elevation in risk for birth asphyxia mortality compared to term infants of afebrile mothers.
CONCLUSIONS. Maternal infections, prematurity, and multiple births are important risk factors for birth asphyxia mortality in the low-resource, community-based setting. Low socioeconomic status is highly associated with birth asphyxia, and the mechanisms leading to mortality need to be elucidated. The interaction between maternal infections and prematurity may be an important target for future community-based interventions to reduce the global impact of birth asphyxia on neonatal mortality.

BACKGROUND. Fibrodysplasia ossificans progressiva is a rare and disabling genetic condition characterized by congenital malformation of the great toes and by progressive heterotopic ossification in specific anatomic patterns. Most patients with fibrodysplasia ossificans progressiva are misdiagnosed early in life before the appearance of heterotopic ossification and undergo diagnostic procedures that can cause lifelong disability. Recently, the genetic cause of fibrodysplasia ossificans progressiva was identified, and definitive genetic testing for fibrodysplasia ossificans progressiva is now available before the appearance of heterotopic ossification.
METHODS. We recently evaluated 7 children for diagnosis of fibrodysplasia ossificans progressiva before the onset of heterotopic ossification. A medical history, physical examination, and skeletal survey were obtained on all of the patients, as well as clinical genetic testing for the canonical fibrodysplasia ossificans progressiva mutation.
RESULTS. All 7 of the children (4 girls and 3 boys; ages 3 months to 6 years) had congenital malformations of the great toes, but none had radiographic evidence of heterotopic ossification at the time of evaluation. Five of the 7 children had soft tissue lesions of the neck and back, suggestive of early fibrodysplasia ossificans progressiva flare-ups, 3 of whom had undergone invasive diagnostic procedures that exacerbated their condition. Two children had no history or signs of soft tissue swelling or flare-ups. DNA sequence analysis found that all 7 of the children had the recurrent fibrodysplasia ossificans progressiva missense mutation, a single nucleotide substitution (c.617G&gt;A) at codon 206 in the glycine-serine activation domain of activin receptor IA, a bone morphogenetic protein type 1 receptor.
CONCLUSION. Clinical suspicion of fibrodysplasia ossificans progressiva early in life on the basis of malformed great toes can lead to early clinical diagnosis, confirmatory diagnostic genetic testing, and the avoidance of additional harmful diagnostic and treatment procedures. This is the first report of genetic confirmation of fibrodysplasia ossificans progressiva before the appearance of heterotopic ossification. Pediatricians should be aware of the early diagnostic features of fibrodysplasia ossificans progressiva, even before the appearance of heterotopic ossification. This awareness should prompt early genetic consultation and testing and the institution of assiduous precautions to prevent iatrogenic harm.

OBJECTIVE. The goal was to investigate the epidemiologic features of antipsychotic prescribing to children and adolescents in general practice in the United Kingdom.
METHODS. A total of 384 participating general practices from the United Kingdom General Practice Research Database were used to identify patients 0 to 18 years of age who were prescribed ≥1 antipsychotic medication between January 1, 1992, and December 31, 2005. Annual age-specific prevalences and incidences of antipsychotic prescribing were calculated.
RESULTS. The overall prevalence of use of all antipsychotics increased from 1992 (0.39 users per 1000 patient-years) to 2005 (0.77 users per 1000 patient-years). The prescribing prevalence for patients 7 to 12 years of age almost tripled between 1992 (0.23 users per 1000 patient-years) and 2005 (0.61 users per 1000 patient-years). Atypical antipsychotic prescribing increased 60-fold from 1994 (0.01 users per 1000 patient-years) to 2005 (0.61 users per 1000 patient-years). However, typical antipsychotic prescribing decreased significantly from 2000 (0.44 users per 1000 patient-years) to 2005 (0.18 users per 1000 patient-years). The incidences for typical and atypical antipsychotics showed trends similar to those of the respective prevalences. However, the overall incidence (number of new starters) for all antipsychotics was relatively stable between 1992 and 2005, which suggests that patients remain on treatment longer.
CONCLUSIONS. The overall prevalence of antipsychotics almost doubled between 1992 and 2005; however, the rate of increase was much lower than the reported figures in the United States. The prescribing of atypical antipsychotic drugs has increased despite the lack of conclusive evidence showing their superiority over older conventional antipsychotics. Additional investigation is required to evaluate their efficacy and safety in children and adolescents.

Published: May 2008

INTRODUCTION. Habitual snoring and obstructive sleep apnea have been associated with bed-wetting in children, and effective obstructive sleep apnea treatment may improve enuresis.
OBJECTIVES. The purpose of this work was to assess whether habitual snoring is associated with increased incidence of enuresis and whether severity of obstructive sleep apnea correlates with enuretic frequency and to evaluate brain natriuretic peptide levels.
METHODS. Parental surveys of 5- to 7-year-old children were reviewed for habitual snoring and enuresis. Enuresis was also assessed in a cohort of 378 children with habitual snoring undergoing overnight polysomnographic evaluation, and brain natriuretic peptide plasma levels were determined in 20 children with obstructive sleep apnea, 20 with habitual snoring without obstructive sleep apnea, and 20 nonsnoring children, matched for enuresis.
RESULTS. There were 17646 surveys completed (50.6% boys; 18.3% black). A total of 1976 (11.2%) of these children were habitual snoring (53% boys; 25.2% black). A total of 531 habitual snoring children also had enuresis (26.9%), with a predominant representation of boys (472 boys [87.5%]). Among the 15670 nonsnoring children, enuresis was reported in 1821 children (11.6%), of whom 88.8% were boys. However, enuresis among 378 children with habitual snoring did not correlate with the magnitude of sleep respiratory disturbances. Indeed, enuresis was reported in 33 of 149 children with obstructive sleep apnea (obstructive apnea hypopnea index: &gt;2 per hour of total sleep time; 53% boys) as compared with 36 habitual snoring children with enuresis (62% boys) and obstructive apnea hypopnea index &lt;2 per hour of total sleep time. Brain natriuretic peptide levels were elevated among children with enuresis and were marginally increased among children with obstructive sleep apnea.
CONCLUSIONS. Habitual snoring is associated with increased prevalence of enuresis, and brain natriuretic peptide levels are increased in enuretic children with further increases with obstructive sleep apnea. However, the prevalence of enuresis is not modified by severity of sleep disturbance. Even mild increases in sleep pressure because of habitual snoring may raise the arousal threshold and promote enuresis, particularly among prone children, that is, those with elevated brain natriuretic peptide levels.

OBJECTIVE. Invasive aspergillosis is a major cause of morbidity and mortality in immunocompromised children. Invasive aspergillosis has been well characterized in adults; however, the incidence and analysis of risk factors, diagnostic tools, treatments, and outcomes have not been well described for a large cohort of pediatric patients.
METHODS. We conducted the largest retrospective review of contemporary cases of proven and probable pediatric invasive aspergillosis diagnosed at 6 major medical centers (January 1, 2000, to July 1, 2005).
RESULTS. Aspergillus fumigatus was the species most frequently recovered (52.8%) for the 139 patients analyzed. The majority of the children had a malignancy with or without hematopoietic stem cell transplant. Significant risk factors that impacted survival were immunosuppressive therapies and allogeneic stem cell transplant. The most common clinical site of invasive aspergillosis was the lungs (59%), and the most frequent diagnostic radiologic finding was nodules (34.6%). Only 2.2% of children showed the air crescent sign, 11% demonstrated the halo sign, and cavitation was seen in 24.5% of patients. Before the diagnosis of invasive aspergillosis, 43.1% of patients received fluconazole, and 39.2% received liposomal amphotericin B. After the diagnosis of invasive aspergillosis, 57% were treated with a lipid formulation of amphotericin B; however, 45.8% received ≥3 concomitant antifungal agents. Analysis did not show superiority of any 1 antifungal related to overall mortality. A total of 52.5% (73 of 139) died during treatment for invasive aspergillosis. Of all the interventions implemented, surgery was the only independent predictor of survival.
CONCLUSIONS. Our analyses revealed common findings between adult and pediatric invasive aspergillosis. However, one key difference is diagnostic radiologic findings. Unlike adults, children frequently do not manifest cavitation or the air crescent or halo signs, and this can significantly impact diagnosis. Immune reconstitution, rather than specific antifungal therapy, was found to be the best predictor of survival.
Unbound Bilirubin Concentration is Associated With Abnormal Automated Auditory Brainstem Response for Jaundiced Newborns

Published: May 2008

OBJECTIVE. This study was conducted to determine whether incidental jaundice affects automated auditory brainstem response results.METHODS. We reviewed the medical charts of jaundiced newborns of ≥34 weeks of gestation who underwent automated auditory brainstem response testing within 4 hours of plasma total bilirubin concentration and unbound bilirubin concentration measurements. We tested the hypothesis that the likelihood of abnormal automated auditory brainstem response results would increase as total bilirubin and unbound bilirubin concentrations increased.RESULTS. Forty-four infants with proximate total bilirubin concentration, unbound bilirubin concentration, and automated auditory brainstem response measurements were identified, and 4 (9%) had bilateral refer automated auditory brainstem response results. The mean total bilirubin concentration of 21.4 mg/dL (SD: 4.0 mg/dL; range: 14.4–29.5 mg/dL) for the 40 infants with bilateral pass automated auditory brainstem response results was not significantly different from that of 23.0 mg/dL (range: 14.9–33.1 mg/dL) for the 4 infants with bilateral refer automated auditory brainstem response results. However, the mean unbound bilirubin concentration of 1.32 μg/dL (range: 0.22–2.99 μg/dL) for the 40 infants with bilateral pass results was significantly lower than the mean of 2.62 μg/dL (range: 0.88–4.41 μg/dL) for the 4 infants with bilateral refer results. Logistic regression showed that increasing unbound bilirubin concentrations but not increasing total bilirubin concentrations were associated with of bilateral refer automated auditory brainstem response results.CONCLUSIONS. The probability of bilateral refer automated auditory brainstem response results increases significantly with increasing unbound bilirubin concentrations but not with increasing total bilirubin concentrations. Because unbound bilirubin concentrations are also more closely correlated with bilirubin neurotoxicity than are total bilirubin concentrations, bilateral refer automated auditory brainstem response results for jaundiced newborns may indicate increased risk of bilirubin neurotoxicity, in addition to the possibility of congenital deafness.
