RESUMO
OBJECTIVE: To characterize barriers to and facilitators of successful iron therapy in young children with iron deficiency anemia (IDA) from an in-depth parental perspective. STUDY DESIGN: Prospective, mixed methods study of children age 9 months to 4 years with a diagnosis of nutritional IDA by clinical history and laboratory criteria and their parents. Clinical data were obtained from the electronic health record. Semistructured interviews focused on knowledge of IDA, clinical effects, experience with iron therapies, and motivation were conducted with the parent who identified as the child's primary caregiver. RESULTS: Twenty patient-parent dyads completed the study; 80% (n = 16) identified as Hispanic/Latino (white). Patients' median age was 23 months (50% male); median initial hemoglobin concentration was 8.2 g/dL and duration of oral iron therapy was 3 months. Parents' median age was 29 years (85% female); 8 interviews (40%) were conducted in Spanish. Barriers included difficulty in administering oral iron owing to side effects and poor taste. Facilitators included provision of specific instructions; support from healthcare providers and additional caregivers at home; motivation to benefit child's health, which was strengthened by strong emotional reactions (ie, stress, anxiety) to therapy and follow-up; and an appreciation of child's improvement with successful completion of therapy. CONCLUSIONS: Our findings support the need for interventions designed to promote oral iron adherence in children with IDA. Rather than focusing on knowledge content related to IDA, interventions should aim to increase parental motivation by emphasizing the health benefits of adhering to iron therapy and avoiding more invasive interventions.

OBJECTIVE: To characterize features of antithrombin concentrate (ATC) use in children receiving unfractionated heparin (UFH) therapy for acute thrombosis. STUDY DESIGN: All pediatric patients at Texas Children's Hospital who received ATC in the context of UFH therapy for acute thrombosis during February 2011 to May 2013 were analyzed. RESULTS: Fifty-one children received ATC during UFH therapy for acute thrombosis. Median age was 3 months (IQR 1 to 18 months). Clinical indications included venous (53%), arterial (37%), venous and arterial (6%), and intracardiac (4%) thrombosis. Median baseline antithrombin (AT) level was 61% and UFH dose was 26 U/kg/h. The median dose of ATC was 49.9 IU/kg (IQR 32.6 to 50.0 IU/kg). Although most patients (86%) did not undergo a change in UFH dose, there was a significant increase in both AT and anti-factor Xa level after the first dose of ATC (P < .001 for both). There was no correlation between ATC dose or increment in AT level above baseline and the achievement of targeted anticoagulation by anti-factor X activity level. Adverse bleeding events occurred in 10% of patients. CONCLUSIONS: There was a significant change in AT and anti-factor Xa activity level after a single dose of ATC despite little to no change in dose of UFH. ATC appears to facilitate anticoagulation with UFH in some children with acute thrombosis but the degree of response is variable and dependent on factors identified in this study. Bleeding and other theoretical risks must be carefully considered.

OBJECTIVE: To determine whether elective cholecystectomy is justifiable in children with sickle cell disease (SCD), gallbladder abnormalities, and minimal clinical symptoms. STUDY DESIGN: A retrospective review comparing clinical presentations and abdominal ultrasound results with outcomes in 146 children with SCD. RESULTS: Ultrasound examination showed sludge or stones in 83 of 146 children (57%). This was found during a diagnostic ultrasound in 59 patients (71%) and during a screening ultrasound in 24 asymptomatic patients (29%). Fifty-four (65%) children with a positive ultrasound underwent cholecystectomy; 13 of these were initially asymptomatic patients who had subsequent development of clinical symptoms. Of the patients with cholecystectomy, 93% had histopathologic evidence of cholecystitis. Perioperative complications were rare, and there were no episodes of postoperative acute chest syndrome. Children who underwent elective surgery had an average 12-days-shorter overall hospital stay than those who underwent emergent surgery (4 vs 16 days, P <.001). CONCLUSIONS: Elective laparoscopic cholecystectomy may be safely performed in children with SCD. Surgery should be strongly considered at the time of gallstone diagnosis before symptoms or complications develop. Histopathologic chronic cholecystitis does not correlate with clinical symptoms.
