- Abstract
IMPORTANCE: Use of hypotonic intravenous fluids for maintenance requirements is associated with increased risk of hyponatremia that results in morbidity and mortality in children. Clinical trial data comparing isotonic and hypotonic maintenance fluids in nonsurgical hospitalized pediatric patients outside intensive care units are lacking. OBJECTIVE: To compare isotonic (sodium chloride, 0.9%, and dextrose, 5%) with hypotonic (sodium chloride, 0.45%, and dextrose, 5%) intravenous maintenance fluids in a hospitalized general pediatric population. DESIGN, SETTING, AND PARTICIPANTS: In this double-blind randomized clinical trial,we recruited 110 children admitted to a general pediatric unit of a tertiary care children’s hospital from March 1, 2008, through August 31, 2012 (age range, 1 month to 18 years), with normal baseline serum sodium levels who were anticipated to require intravenous maintenance fluids for 48 hours or longer (intent-to-treat analyses). Children with diagnoses that required specific fluid tonicity and volumes were excluded. INTERVENTIONS: Patients were randomized to receive isotonic or hypotonic intravenous fluid at maintenance rates for 48 hours. MAIN OUTCOMES AND MEASURES: The primary outcome was mean serum sodium level at 48 hours. The secondary outcomes were mean sodium level at 24 hours, hyponatremia and hypernatremia, weight gain, hypertension, and edema. Confounding variables were included in multiple regression models. Post hoc analyses included change from baseline sodium level at 24 and 48 hours and subgroup analysis of children with primary respiratory diagnosis. RESULTS: Of 110 enrolled patients, 54 received isotonic fluids and 56 received hypotonic fluids. The mean (SD) sodium level at 48 hours was 139.9 (2.7) mEq/L in the isotonic group and 139.6 (2.6) mEq/L in the hypotonic group (95% CI of the difference, −0.94 to 1.74 mEq/L; P = .60). Two patients in the hypotonic group developed hyponatremia, 1 in each group developed hypernatremia, 2 in each group developed hypertension, and 2 in the isotonic group developed edema. Mean (SD) change from baseline to 48-hour sodium level was +1.3 (2.9) vs −0.12 (2.8) mEq/L, respectively (absolute difference, 1.4 mEq/L; 95% CI of the difference, −0.01 to 2.8 mEq/L; P = .05). CONCLUSIONS AND RELEVANCE: Our study results support the notion that isotonic maintenance fluid administration is safe in general pediatric patients and may result in fewer cases of hyponatremia.

Savlov, Deena, Beck, Carolyn E., DeGroot, Julie, Odame, Isaac, and Friedman, Jeremy N.
- Abstract
Bacterial sepsis is more common and potentially life threatening in children with sickle cell disease (SCD). Identification of variables that predict bacteremia may aid clinicians in recognizing patients with SCD at higher risk for sepsis.

- Abstract
IMPORTANCE Alopecia areata is an idiopathic cause of hair loss with limited therapeutic repertoire. OBJECTIVE To compare the efficacy and safety of a high- vs low-potency topical corticosteroid in pediatric patients. DESIGN, SETTING, AND PARTICIPANTS This single-center, randomized, blind, 2-arm, parallel-group, superiority trial was carried out over a 24-week period at a tertiary referral academic dermatology clinic at The Hospital for Sick Children in Toronto, Ontario, Canada. Forty-two children attending the outpatients clinic, 2 to 16 years of age with alopecia areata affecting at least 10% of scalp surface area, were eligible; 1 declined to participate. There were no withdrawals from the study. INTERVENTIONS FOR CLINICAL TRIALS Patients were randomly assigned to receive clobetasol propionate, 0.05% cream, or hydrocortisone, 1%, cream. Patients applied a thin layer of the assigned cream twice daily to the areas of hair loss for 2 cycles of 6 weeks on, 6 weeks off, for a total of 24 weeks. MAIN OUTCOMES AND MEASURES The primary outcome was the change in scalp surface area with hair loss over 24 weeks following enrollment. RESULTS All participants were assessed at 6, 12, 18, and 24 weeks (except 1 participant who missed the 6-week visit). After adjusting for baseline hair loss, the clobetasol group had a statistically significant (P < .001) greater decrease in the surface area with hair loss, compared with the hydrocortisone group at all time points except at 6 weeks. One patient with extensive alopecia areata experienced skin atrophy that resolved spontaneously in 6 weeks. There was no difference observed in the number of patients with abnormal urinary cortisol at the beginning and the end of the study. CONCLUSIONS AND RELEVANCE Topical clobetasol propionate, 0.05%, cream is efficacious and safe as a first-line agent for limited patchy childhood alopecia areata. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01453686.

- Abstract
OBJECTIVES To determine the effect of modifiable dietary intake variables (current vitamin D supplementation and daily cow's milk intake) on 25-hydroxyvitamin D level in early childhood and to evaluate the relationship between these modifiable dietary factors and other largely nonmodifiable determinants of vitamin D status including skin pigmentation and season. DESIGN Cross-sectional study. SETTING Primary care pediatric and family medicine practices participating in the TARGet Kids! practice-based research network in Toronto, Ontario, Canada. PARTICIPANTS From December 2008 to June 2011, healthy children 1 to 5 years of age were recruited during a routine physician's visit. INTERVENTIONS Survey, anthropometric measurements, and laboratory data were collected. A multivariable linear regression model was developed to examine the independent effects of vitamin D supplementation and daily volume of cow's milk on 25-hydroxyvitamin D level. MAIN OUTCOME MEASURES 25-Hydroxyvitamin D level. RESULTS Blood was obtained in 1898 children. Two modifiable dietary intake variables, vitamin D supplementation and cow's milk, increased 25-hydroxyvitamin D level by 3.4 ng/mL (95% CI, 2-4 ng/mL) and 1.6 ng/mL per 250-mL cup per day (95% CI, 1-2 ng/mL), respectively. Two nonmodifiable variables reflecting cutaneous vitamin D synthesis (skin pigmentation and season) were also strongly associated with 25-hydroxyvitamin D status but accounted for a much smaller proportion of the explained variation in 25-hydroxyvitamin D level. The effect of vitamin D supplementation and milk intake on 25-hydroxyvitamin D level appeared similar regardless of skin pigmentation or season. CONCLUSION Two modifiable dietary intake variables (vitamin D supplementation and cow's milk intake) are the most important determinants of 25-hydroxyvitamin D status in early childhood.
