Effect of parents' wartime deployment on the behavior of young children in military families.

OBJECTIVE To describe the effect of wartime military deployments on the behavior of young children in military families. DESIGN Cross-sectional study. SETTING Childcare centers on a large Marine base. PARTICIPANTS Parents and childcare providers of children aged 1(1/2) to 5 years enrolled in on-base childcare centers. Main Exposure Parental deployment. OUTCOME MEASURES Mean externalizing, internalizing, and total symptom scores on the Child Behavior Checklist (CBCL) (1(1/2)-5 years) and the CBCL-Teacher Report Form (TRF) (1(1/2)-5 years). RESULTS One hundred sixty-nine of 233 consenting families (73%) participated. Nonresponders did not differ from responders in their childs age or TRF scores. Fifty-five children (33%) had a deployed parent. Parents with children aged 3 years or older and a deployed spouse had significantly higher depression scores than those without a deployed spouse. There were no differences in the demographic characteristics between groups. After controlling for respondents age, stress and depressive symptoms, deployed service members rank, and total number of children in the home, we found an age by deployment interaction: children aged 3 years or older with a deployed parent had significantly higher CBCL externalizing and total scores (externalizing, 48.50 vs 43.31, P < .05; total, 47.71 vs 42.68, P < .05) and externalizing and total TRF scores (externalizing, 50.21 vs 45.62, P < .05; total, 48.54 vs 43.73, P < .05) compared with same-aged peers without a deployed parent. CONCLUSIONS This study is the first to show that children aged 3 years or older with a deployed parent exhibit increased behavioral symptoms compared with peers without a deployed parent after controlling for caregivers stress and depressive symptoms.

Efficacy of Neonatal Release of Ankyloglossia: A Randomized Trial

BACKGROUND: Ankyloglossia has been associated with a variety of infant-feeding problems. Frenotomy commonly is performed for relief of ankyloglossia, but there has been a lack of convincing data to support this practice. OBJECTIVES: Our primary objective was to determine whether frenotomy for infants with ankyloglossia improved maternal nipple pain and ability to breastfeed. A secondary objective was to determine whether frenotomy improved the length of breastfeeding. METHODS: Over a 12-month period, neonates who had difficulty breastfeeding and significant ankyloglossia were enrolled in this randomized, single-blinded, controlled trial and assigned to either a frenotomy (30 infants) or a sham procedure (28 infants). Breastfeeding was assessed by a preintervention and postintervention nipple-pain scale and the Infant Breastfeeding Assessment Tool. The same tools were used at the 2-week follow-up and regularly scheduled follow-ups over a 1-year period. The infants in the sham group were given a frenotomy before or at the 2-week follow-up if it was desired. RESULTS: Both groups demonstrated statistically significantly decreased pain scores after the intervention. The frenotomy group improved significantly more than the sham group (P < .001). Breastfeeding scores significantly improved in the frenotomy group (P = .029) without a significant change in the control group. All but 1 parent in the sham group elected to have the procedure performed when their infant reached 2 weeks of age, which prevented additional comparisons between the 2 groups. CONCLUSIONS: We demonstrated immediate improvement in nipple-pain and breastfeeding scores, despite a placebo effect on nipple pain. This should provide convincing evidence for those seeking a frenotomy for infants with signficant ankyloglossia.

Identification of Children and Adolescents at Risk for Renal Scarring After a First Urinary Tract Infection: A Meta-analysis With Individual Patient Data

IMPORTANCE No studies have systematically examined the accuracy of clinical, laboratory, and imaging variables in detecting renal scarring in children and adolescents with a first urinary tract infection. OBJECTIVES To identify independent prognostic factors for the development of renal scarring and to combine these factors in prediction models that could be useful in clinical practice. DATA SOURCES MEDLINE and EMBASE. STUDY SELECTION We included patients aged 0 to 18 years with a first urinary tract infection who underwent follow-up renal scanning with technetium Tc 99m succimer at least 5 months later. DATA EXTRACTION AND SYNTHESIS We pooled individual patient data from 9 cohort studies. MAIN OUTCOMES AND MEASURES We examined the association between predictor variables assessed at the time of the first urinary tract infection and the development of renal scarring. Renal scarring was defined by the presence of photopenia on the renal scan. We assessed the following 3 models: clinical (demographic information, fever, and etiologic organism) and ultrasonographic findings (model 1); model 1 plus serum levels of inflammatory markers (model 2); and model 2 plus voiding cystourethrogram findings (model 3). RESULTS Of the 1280 included participants, 199 (15.5%) had renal scarring. A temperature of at least 39°C, an etiologic organism other than Escherichia coli, an abnormal ultrasonographic finding, polymorphonuclear cell count of greater than 60%, C-reactive protein level of greater than 40 mg/L, and presence of vesicoureteral reflux were all associated with the development of renal scars (P ≤ .01 for all). Although the presence of grade IV or V vesicoureteral reflux was the strongest predictor of renal scarring, this degree of reflux was present in only 4.1% of patients. The overall predictive ability of model 1 with 3 variables (temperature, ultrasonographic findings, and etiologic organism) was only 3% to 5% less than the predictive ability of models requiring a blood draw and/or a voiding cystourethrogram. Patients with a model 1 score of 2 or more (21.7% of the sample) represent a particularly high-risk group in whom the risk for renal scarring was 30.7%. At this cutoff, model 1 identified 44.9% of patients with eventual renal scarring. CONCLUSIONS AND RELEVANCE Children and adolescents with an abnormal renal ultrasonographic finding or with a combination of high fever (≥39°C) and an etiologic organism other than E coli are at high risk for the development of renal scarring.

Comparing Patients Seen in Pediatric Resident Continuity Clinics and National Ambulatory Medical Care Survey Practices: A Study From the Continuity Research Network

OBJECTIVES. The goal was to compare visit data from Continuity Research Network practices with data for a nationally representative sample of pediatric visits in practice settings from the National Ambulatory Medical Care Survey. METHODS. A cross-sectional study comparing data for Continuity Research Network practice visits during a 1-week period in 2002 with data from the 2000 National Ambulatory Medical Care Survey was performed. Continuity Research Network and National Ambulatory Medical Care Survey data were derived from 30 patient visits per practice site for patients <22 years of age, with the primary care providers being residents and practicing pediatricians, respectively. RESULTS. Eighteen Continuity Research Network practices reported on 540 visits, compared with 32 National Ambulatory Medical Care Survey physicians reporting on 792 visits. Continuity Research Network patients were more likely to be black non-Hispanic or Hispanic/Latino and to have public insurance. The top 5 reasons for visits were the same for Continuity Research Network and National Ambulatory Medical Care Survey visits, although the orders varied slightly. These 5 reasons accounted for 58% of Continuity Research Network visits and 49% of National Ambulatory Medical Care Survey visits. Continuity Research Network visits were more likely to result in patient instructions to return at a specific time (78% vs 52%). CONCLUSIONS. Residents in Continuity Research Network practices provide care to more underserved patients but evaluate problems that are similar to those observed in office practices; the Continuity Research Network practices thus provide important training experiences for residents who will serve both minority and nonminority children.

Shortened Antimicrobial Treatment for Acute Otitis Media in Young Children

BACKGROUND Limiting the duration of antimicrobial treatment constitutes a potential strategy to reduce the risk of antimicrobial resistance among children with acute otitis media. METHODS We assigned 520 children, 6 to 23 months of age, with acute otitis media to receive amoxicillin-clavulanate either for a standard duration of 10 days or for a reduced duration of 5 days followed by placebo for 5 days. We measured rates of clinical response (in a systematic fashion, on the basis of signs and symptomatic response), recurrence, and nasopharyngeal colonization, and we analyzed episode outcomes using a noninferiority approach. Symptom scores ranged from 0 to 14, with higher numbers indicating more severe symptoms. RESULTS Children who were treated with amoxicillin-clavulanate for 5 days were more likely than those who were treated for 10 days to have clinical failure (77 of 229 children [34%] vs. 39 of 238 [16%]; difference, 17 percentage points [based on unrounded data]; 95% confidence interval, 9 to 25). The mean symptom scores over the period from day 6 to day 14 were 1.61 in the 5-day group and 1.34 in the 10-day group (P=0.07); the mean scores at the day-12-to-14 assessment were 1.89 versus 1.20 (P=0.001). The percentage of children whose symptom scores decreased more than 50% (indicating less severe symptoms) from baseline to the end of treatment was lower in the 5-day group than in the 10-day group (181 of 227 children [80%] vs. 211 of 233 [91%], P=0.003). We found no significant between-group differences in rates of recurrence, adverse events, or nasopharyngeal colonization with penicillin-nonsusceptible pathogens. Clinical-failure rates were greater among children who had been exposed to three or more children for 10 or more hours per week than among those with less exposure (P=0.02) and were also greater among children with infection in both ears than among those with infection in one ear (P<0.001). CONCLUSIONS Among children 6 to 23 months of age with acute otitis media, reduced-duration antimicrobial treatment resulted in less favorable outcomes than standard-duration treatment; in addition, neither the rate of adverse events nor the rate of emergence of antimicrobial resistance was lower with the shorter regimen.

Emergence of streptococcus pneumoniae Serogroups 15 and 35 in Nasopharyngeal Cultures From Young Children With Acute Otitis Media

Background: Surveillance of children with acute otitis media (AOM) for nasopharyngeal colonization with Streptococcus pneumoniae before, during and after the introduction of 7-valent pneumococcal conjugate vaccine (PCV7) indicated the near-complete elimination of PCV7 strains and the emergence of pneumococcal serotype 19A. Methods: To determine effects of the introduction of 13-valent pneumococcal conjugate vaccine (PCV13) on pneumococcal nasopharyngeal colonization, we obtained nasopharyngeal cultures from 228 children 6 through 23 of age months presenting with a new episode of AOM during 2012 and 2013 and enrolled in an ongoing clinical trial of antimicrobial efficacy. All children had received at least 2 doses of PCV13. The S. pneumoniae isolates were subjected to serotyping and testing for antimicrobial susceptibility. We compared the findings with results obtained in 3 earlier studies. Results: We found nasopharyngeal colonization with S. pneumoniae in 113 (50%) of the children with AOM. PCV7 and PCV13 serotypes accounted for 2% and 12%, respectively, of the pneumococcal isolates. Of the 14 PCV13 isolates, 8 were serotype 19A. Nonvaccine serotypes accounted for 69% of the isolates. Most frequently occurring were subtypes of serotype 15 (23%) and serotype 35B (9%). Overall, 33% of the isolates were penicillin nonsusceptible, a proportion not significantly different from proportions found in our 3 earlier studies (26%, 36% and 37%, respectively). Serotypes 15 and 35B accounted for 51% of penicillin-nonsusceptible isolates. Conclusions: Expansion of contents of pneumococcal vaccine administered to children is followed by not-fully-predictable changes in nasopharyngeal pneumococcal colonization. Continued surveillance is required to help inform future vaccine development.

Association Between Uropathogen and Pyuria

OBJECTIVE: We sought to determine factors associated with the absence of pyuria in symptomatic children whose urine culture was positive for a known uropathogen. METHODS: We obtained data on children evaluated at the Children’s Hospital of Pittsburgh emergency department between 2007 and 2013 with symptoms of urinary tract infection (UTI) who had paired urinalysis and urine cultures. We excluded children with an unknown or bag urine collection method, major genitourinary anomalies, immunocompromising conditions, or with multiple organisms on culture. We chose a single, randomly-selected urine specimen per child and limited the analysis to those with positive cultures. RESULTS: There were 46 158 visits during the study period; 1181 children diagnosed with UTI met all inclusion criteria and had a microscopic urinalysis for pyuria. Pyuria (≥5 white blood cells per high-powered field or ≥10 white blood cells per cubic millimeter) was present in 1031 (87%) children and absent in 150 (13%). Children with Enterococcus species, Klebsiella species, and Pseudomonas aeruginosa were significantly less likely to exhibit pyuria than children with Escherichia coli (odds ratio of 0.14, 0.34, and 0.19, respectively). Children with these organisms were also less likely to have a positive leukocyte esterase on dipstick urinalysis. Results were similar when we restricted the analysis to children whose urine samples were collected by bladder catheterization. CONCLUSIONS: We found that certain uropathogens are less likely to be associated with pyuria in symptomatic children. Identification of biomarkers more accurate than pyuria or leukocyte esterase may help reduce over- and undertreatment of UTIs.

Light field otoscope design for 3D in vivo imaging of the middle ear

We present a light field digital otoscope designed to measure three-dimensional shape of the tympanic membrane. This paper describes the optical and anatomical considerations we used to develop the prototype, along with the simulation and experimental measurements of vignetting, field curvature, and lateral resolution. Using an experimental evaluation procedure, we have determined depth accuracy and depth precision of our system to be 0.05-0.07 mm and 0.21-0.44 mm, respectively. To demonstrate the application of our light field otoscope, we present the first three-dimensional reconstructions of tympanic membranes in normal and otitis media conditions, acquired from children who participated in a feasibility study at the Childrens Hospital of Pittsburgh of the University of Pittsburgh Medical Center.

Corneal Abrasions in Young Infants

OBJECTIVES: We sought to determine the prevalence of corneal abrasions and possible associations with fingernail length, demographic information, sleeping, and crying among young infants. METHODS: Parents of 1- to 12-week-old infants without symptoms who were presenting for well-child visits completed a brief questionnaire on age, gender, race, fingernail-trimming practices, and sleeping and crying in the preceding 24-hour period. Fingernail length was measured, and eyes were examined through staining with fluorescein and illumination/magnification with a Bluminator (Eidolon Optical, Natick, MA). Patients with corneal abrasions were given orally administered acetaminophen and erythromycin ointment. Masked interrater reliability for abrasions was measured. Logistic regression analyses determined the association of corneal abrasions with potential covariates. RESULTS: Ninety-six subjects were enrolled, including 47 girls (49%), with a mean age of 32.2 days (SD: 21.7 days). Forty-seven infants (49%) had abrasions. Demographic variables and mean crying times (114.8 ± 124.9 vs 86.5 ± 111.7 minutes; P < .24) were not significantly different for infants with and without abrasions. Infants with abrasions slept more (15.9 ± 3.3 vs 14.5 ± 3.6 hours; P = .054). Associations of fingernail-trimming method and fingernail length with corneal abrasions were not statistically significant. Masked interrater reliability was high, with agreement between the primary investigator and the associate investigator for 20 (91%) of 22 eyes and agreement between the primary investigator and a pediatric ophthalmologist for 9 (90%) of 10 eyes. CONCLUSIONS: Corneal abrasions are extremely common among 1- to 12-week-old infants and have unclear clinical significance. Primary care physicians should be careful about attributing unexplained persistent crying to corneal abrasions, potentially missing a more-serious problem.

Infectious diseases in early education and child care programs.

1. Timothy R. Shope, MD, MPH* 1. *Department of Pediatrics, Division of General Academic Pediatrics, Childrens Hospital of Pittsburgh of University of Pittsburgh Medical Center, Pittsburgh, PA. * Abbreviations: AAP: : American Academy of Pediatrics CFOC3: : Caring for Our Children , 3rd ed ECE: : early care and education RSV: : respiratory syncytial virus Out-of-home care and education are the norms for most young children and lead to increased exposure to infectious diseases. Pediatricians need to be aware of strategies to reduce the risk of infection and guidelines for determining exclusion and return to care for mildly ill children who participate in group care arrangements. After completing this article, readers should be able to: 1. Recognize the risks of infectious diseases in children who participate in early care and education programs. 2. Understand methods for reducing infectious diseases in early care and education settings. 3. Identify which infectious diseases require exclusion from early care and education programs. Two-thirds of children younger than 6 years participate in nonparental out-of-home early education and child care. Demographic trends during the past several decades reflect an increased desire and need to work for men and women who are parents. During the first 2 years of participation, children enrolled in early care and education (ECE) programs experience a higher incidence of respiratory and diarrheal infections, otitis media, and antibiotic-resistant bacteria compared with their peers primarily cared for at home. The types of infection generally reflect common respiratory and gastrointestinal viruses in circulation in the community. However, there are some infectious diseases that can cause outbreaks or clusters of infections in ECE settings. When ill children are excluded from an ECE facility, parents may miss work, lose income, and seek health care services in an effort to return their children to child care. Pediatricians need to be aware of the infectious disease risks of child care attendance and various strategies for reducing them. In addition, pediatricians need to be knowledgeable about rational exclusion and return …
