BACKGROUND AND OBJECTIVE: High-flow therapy is the most recent, and popular, mode
of respiratory support in neonates. However, the evidence supporting its efficacy
and safety has not yet been established. We conducted a systematic review and
meta-analysis of clinical trials comparing efficacy and safety of high-flow
therapy compared with other modes of noninvasive ventilation (NIV) in preterm
METHODS: Articles were indexed by using Medline, Embase, Scopus, OpenSIGLE,
Health Management Information Consortium, and Cochrane Central Register of
Controlled Trials. Randomized or quasi-randomized clinical trials involving
preterm infants, comparing high-flow therapy with other modes of NIV, and
reporting extractable data on relevant outcomes, were selected. Data on efficacy,
safety, and other common neonatal outcomes were extracted on predesigned forms.
RESULTS: In this analysis, we included 1112 preterm infants, participating in 9
clinical trials. High-flow therapy was similar in efficacy to other modes of NIV
in preterm infants when used as primary support (odds ratio of failure of
therapy, 1.02 [95% confidence interval: 0.55 to 1.88]), as well as after
extubation (1.09 [0.58 to 2.02]). There were no significant differences in odds
of death (0.48 [0.18 to 1.24]) between the groups. Preterm infants supported on
high-flow had significantly lower odds of nasal trauma (0.13 [0.02 to 0.69]).
CONCLUSIONS: High-flow therapy appears to be similar in efficacy and safety to
other conventional modes of NIV in preterm infants. It is associated with
significantly lower odds of nasal trauma. Caution needs to be exercised in
extreme preterm infants because of the paucity of published data.

OBJECTIVES: To determine whether lidocaine is superior to nonanesthetic lubricant
(NAL) for relieving pain in children undergoing urethral catheterization (UC).
METHODS: Children 0 to 24 months requiring UC were randomized to NAL or topical
and intraurethral 2% lidocaine gel. Primary outcome was facial grimacing in the
pre to during drug administration and catheterization phases. Secondary outcome
was caregiver satisfaction by using a Visual Analog Scale.
RESULTS: There were 133 participants (n = 68 lidocaine, n = 65 NAL). There were
no significant differences in mean (SD) scores during UC between lidocaine and
NAL (86.4% [121.5%] vs 85.2% [126.6%]), respectively (Δ [confidence interval
(CI)] = -1.2 [-21.0 to 49.0], P = .4). There was a significantly greater
difference in mean (SD) scores during instillation of lidocaine versus NAL (61.8%
[105.6%] vs 3.2% [84.9%]), respectively (Δ [CI] -58.6 [-95.0 to -32.0], P <
.001). There were no significant differences in mean (SD) parental satisfaction
scores between lidocaine and NAL (4.8 [3.2] vs 5.9 [2.9]), respectively (CI-0.1
to 2.2; P = .06). In the subgroup analysis, age, gender, and positive urine
culture did not significantly influence between-group differences in facial
CONCLUSIONS: Compared with NAL, topical and intraurethral lidocaine is not
associated with significant pain reduction during UC, but significantly greater
pain during instillation. Therefore, clinicians may consider using noninvasive
pain-reducing strategies for young children who require UC.

BACKGROUND AND OBJECTIVE: The mainstay of treatment for acute bronchiolitis
remains supportive care. The objective of this study was to assess the efficacy
and safety of nebulized hypertonic saline (HS) in infants with acute
METHODS: Data sources included PubMed and the Virtual Health Library of the Latin
American and Caribbean Center on Health Sciences Information up to May 2015.
Studies selected were randomized or quasi-randomized controlled trials comparing
nebulized HS with 0.9% saline or standard treatment.
RESULTS: We included 24 trials involving 3209 patients, 1706 of whom received HS.
Hospitalized patients treated with nebulized HS had a significantly shorter
length of stay compared with those receiving 0.9% saline or standard care (15
trials involving 1956 patients; mean difference [MD] -0.45 days, 95% confidence
interval [CI] -0.82 to -0.08). The HS group also had a significantly lower
posttreatment clinical score in the first 3 days of admission (5 trials involving
404 inpatients; day 1: MD -0.99, 95% CI -1.48 to -0.50; day 2: MD -1.45, 95% CI
-2.06 to -0.85; day 3: MD -1.44, 95% CI -1.78 to -1.11). Nebulized HS reduced the
risk of hospitalization by 20% compared with 0.9% saline among outpatients (7
trials involving 951 patients; risk ratio 0.80, 95% CI 0.67-0.96). No significant
adverse events related to HS inhalation were reported. The quality of evidence is
moderate due to inconsistency in results between trials and study limitations
(risk of bias).
CONCLUSIONS: Nebulized HS is a safe and potentially effective treatment of
infants with acute bronchiolitis.

BACKGROUND AND OBJECTIVE: Legitimate opioid use is associated with an increased
risk of long-term opioid use and possibly misuse in adults. The objective of this
study was to estimate the risk of future opioid misuse among adolescents who have
not yet graduated from high school.
METHODS: Prospective, panel data come from the Monitoring the Future study. The
analysis uses a nationally representative sample of 6220 individuals surveyed in
school in 12th grade and then followed up through age 23. Analyses are stratified
by predicted future opioid misuse as measured in 12th grade on the basis of known
risk factors. The main outcome is nonmedical use of a prescription opioid at ages
19 to 23. Predictors include use of a legitimate prescription by 12th grade, as
well as baseline history of drug use and baseline attitudes toward illegal drug
RESULTS: Legitimate opioid use before high school graduation is independently
associated with a 33% increase in the risk of future opioid misuse after high
school. This association is concentrated among individuals who have little to no
history of drug use and, as well, strong disapproval of illegal drug use at
CONCLUSIONS: Use of prescribed opioids before the 12th grade is independently
associated with future opioid misuse among patients with little drug experience
and who disapprove of illegal drug use. Clinic-based education and prevention
efforts have substantial potential to reduce future opioid misuse among these
individuals, who begin opioid use with strong attitudes against illegal drug use.

BACKGROUND: Neonatal endotracheal intubation is a necessary skill. However,
success rates among junior doctors have fallen to <50%, largely owing to
declining opportunities to intubate. Videolaryngoscopy allows instructor and
trainee to share the view of the pharynx. We compared intubations guided by an
instructor watching a videolaryngoscope screen with the traditional method where
the instructor does not have this view.
METHODS: A randomized, controlled trial at a tertiary neonatal center recruited
newborns from February 2013 to May 2014. Eligible intubations were performed
orally on infants without facial or airway anomalies, in the delivery room or
neonatal intensive care, by doctors with <6 months' tertiary neonatal experience.
Intubations were randomized to having the videolaryngoscope screen visible to the
instructor or covered (control). The primary outcome was first-attempt intubation
success rate confirmed by colorimetric detection of expired carbon dioxide.
RESULTS: Two hundred six first-attempt intubations were analyzed. Median
(interquartile range) infant gestation was 29 (27 to 32) weeks, and weight was
1142 (816 to 1750) g. The success rate when the instructor was able to view the
videolaryngoscope screen was 66% (69/104) compared with 41% (42/102) when the
screen was covered (P < .001, OR 2.81, 95% CI 1.54 to 5.17). When premedication
was used, the success rate in the intervention group was 72% (56/78) compared
with 44% (35/79) in the control group (P < .001, OR 3.2, 95% CI 1.6 to 6.6).
CONCLUSIONS: Intubation success rates of inexperienced neonatal trainees
significantly improved when the instructor was able to share their view on a
videolaryngoscope screen.

Chapel Hill, Chapel Hill, North Carolina.

BACKGROUND AND OBJECTIVE: Increasing data suggest that neonatal pain has
long-term consequences. Nonpharmacologic techniques (sucrose taste, pacifier
suckling, breastfeeding) are effective and now widely used to combat minor
neonatal pain. This study examined the analgesic effect of sucrose combined with
radiant warmth compared with the taste of sucrose alone during a painful
procedure in healthy full-term newborns.
METHODS: A randomized, controlled trial included 29 healthy, full-term newborns
born at the University of Chicago Hospital. Both groups of infants were given 1.0
mL of 25% sucrose solution 2 minutes before the vaccination, and 1 group
additionally was given radiant warmth from an infant warmer before the
vaccination. We assessed pain by comparing differences in cry, grimace, heart
rate variability (ie, respiratory sinus arrhythmia), and heart rate between the
RESULTS: The sucrose plus warmer group cried and grimaced for 50% less time after
the vaccination than the sucrose alone group (P < .05, respectively). The sucrose
plus warmer group had lower heart rate and heart rate variability (ie,
respiratory sinus arrhythmia) responses compared with the sucrose alone group (P
< .01), reflecting a greater ability to physiologically regulate in response to
the painful vaccination.
CONCLUSIONS: The combination of sucrose and radiant warmth is an effective
analgesic in newborns and reduces pain better than sucrose alone. The ready
availability of this practical nonpharmacologic technique has the potential to
reduce the burden of newborn pain.

BACKGROUND: The 2011 American Academy of Pediatrics urinary tract infection (UTI)
guideline suggests incorporation of a positive urinalysis (UA) into the
definition of UTI. However, concerns linger over UA sensitivity in young infants.
Infants with the same pathogenic organism in the blood and urine (bacteremic UTI)
have true infections and represent a desirable population for examination of UA
METHODS: We collected UA results on a cross-sectional sample of 276 infants <3
months of age with bacteremic UTI from 11 hospital systems. Sensitivity was
calculated on infants who had at least a partial UA performed and had ≥50 000
colony-forming units per milliliter from the urine culture. Specificity was
determined by using a random sample of infants from the central study site with
negative urine cultures.
RESULTS: The final sample included 245 infants with bacteremic UTI and 115
infants with negative urine cultures. The sensitivity of leukocyte esterase was
97.6% (95% confidence interval [CI] 94.5%-99.2%) and of pyuria (>3 white blood
cells/high-power field) was 96% (95% CI 92.5%-98.1%). Only 1 infant with
bacteremic UTI (Group B Streptococcus) and a complete UA had an entirely negative
UA. In infants with negative urine cultures, leukocyte esterase specificity was
93.9% (95% CI 87.9 - 97.5) and of pyuria was 91.3% (84.6%-95.6%).
CONCLUSIONS: In young infants with bacteremic UTI, UA sensitivity is higher than
previous reports in infants with UTI in general. This finding can be explained by
spectrum bias or by inclusion of faulty gold standards (contaminants or
asymptomatic bacteriuria) in previous studies.

OBJECTIVES: To determine if recommending strict rest improved concussion recovery
and outcome after discharge from the pediatric emergency department (ED).
METHODS: Patients aged 11 to 22 years presenting to a pediatric ED within 24
hours of concussion were recruited. Participants underwent neurocognitive,
balance, and symptom assessment in the ED and were randomized to strict rest for
5 days versus usual care (1-2 days rest, followed by stepwise return to
activity). Patients completed a diary used to record physical and mental activity
level, calculate energy exertion, and record daily postconcussive symptoms.
Neurocognitive and balance assessments were performed at 3 and 10 days
postinjury. Sample size calculations were powered to detect clinically meaningful
differences in postconcussive symptom, neurocognitive, and balance scores between
treatment groups. Linear mixed modeling was used to detect contributions of group
assignment to individual recovery trajectory.
RESULTS: Ninety-nine patients were enrolled; 88 completed all study procedures
(45 intervention, 43 control). Postdischarge, both groups reported a 20% decrease
in energy exertion and physical activity levels. As expected, the intervention
group reported less school and after-school attendance for days 2 to 5
postconcussion (3.8 vs 6.7 hours total, P < .05). There was no clinically
significant difference in neurocognitive or balance outcomes. However, the
intervention group reported more daily postconcussive symptoms (total symptom
score over 10 days, 187.9 vs 131.9, P < .03) and slower symptom resolution.
CONCLUSIONS: Recommending strict rest for adolescents immediately after
concussion offered no added benefit over the usual care. Adolescents' symptom
reporting was influenced by recommending strict rest.

BACKGROUND AND OBJECTIVES: Bronchiolitis, the most common reason for
hospitalization in children younger than 1 year in the United States, has no
proven therapies effective beyond supportive care. We aimed to investigate the
effect of nebulized 3% hypertonic saline (HS) compared with nebulized normal
saline (NS) on length of stay (LOS) in infants hospitalized with bronchiolitis.
METHODS: We conducted a prospective, randomized, double-blind, controlled trial
in an urban tertiary care children's hospital in 227 infants younger than 12
months old admitted with a diagnosis of bronchiolitis (190 completed the study); 
113 infants were randomized to HS (93 completed the study), and 114 to NS (97
completed the study). Subjects received 4 mL nebulized 3% HS or 4 mL 0.9% NS
every 4 hours from enrollment until hospital discharge. The primary outcome was
median LOS. Secondary outcomes were total adverse events, subdivided as clinical
worsening and readmissions.
RESULTS: Patient characteristics were similar in groups. In intention-to-treat
analysis, median LOS (interquartile range) of HS and NS groups was 2.1 (1.2-4.6) 
vs 2.1 days (1.2-3.8), respectively, P = .73. We confirmed findings with
per-protocol analysis, HS and NS groups with 2.0 (1.3-3.3) and 2.0 days
(1.2-3.0), respectively, P = .96. Seven-day readmission rate for HS and NS groups
were 4.3% and 3.1%, respectively, P = .77. Clinical worsening events were similar
between groups (9% vs 8%, P = .97).
CONCLUSIONS: Among infants admitted to the hospital with bronchiolitis, treatment
with nebulized 3% HS compared with NS had no difference in LOS or 7-day
readmission rates.

BACKGROUND AND OBJECTIVE: To reduce missed cases of pediatric abusive head trauma
(AHT), Pediatric Brain Injury Research Network investigators derived a 4-variable
AHT clinical prediction rule (CPR) with sensitivity of .96. Our objective was to
validate the screening performance of this AHT CPR in a new, equivalent patient
METHODS: We conducted a prospective, multicenter, observational, cross-sectional
study. Applying the same inclusion criteria, definitional criteria for AHT, and
methods used in the completed derivation study, Pediatric Brain Injury Research
Network investigators captured complete clinical, historical, and radiologic data
on 291 acutely head-injured children <3 years of age admitted to PICUs at 14
participating sites, sorted them into comparison groups of abusive and nonabusive
head trauma, and measured the screening performance of the AHT CPR.
RESULTS: In this new patient population, the 4-variable AHT CPR demonstrated
sensitivity of .96, specificity of .46, positive predictive value of .55,
negative predictive value of .93, positive likelihood ratio of 1.67, and negative
likelihood ratio of 0.09. Secondary analysis revealed that the AHT CPR identified
98% of study patients who were ultimately diagnosed with AHT.
CONCLUSIONS: Four readily available variables (acute respiratory compromise
before admission; bruising of the torso, ears, or neck; bilateral or
interhemispheric subdural hemorrhages or collections; and any skull fractures
other than an isolated, unilateral, nondiastatic, linear, parietal fracture)
identify AHT with high sensitivity in young, acutely head-injured children
admitted to the PICU.
