Feasibility of HLA-Haploidentical Hematopoietic Stem Cell Transplantation With Post-Transplantation Cyclophosphamide for Advanced Pediatric Malignancies

Background. Patients with advanced malignancies in non-complete remission (CR) have a dismal prognosis after HLA-matched hematopoietic stem cell transplantation (HSCT). T-cell-replete HLA-haploidentical HSCT has remarkable anti-leukemia/tumor effects on these patients, but also a high risk of severe/extensive graft-versus-host disease (GHVD). Post-transplantation cyclophosphamide (PTCY) is regarded as a GVHD-specific immunosuppressant in adults, but its feasibility is unknown in children. Methods. We performed a prospective feasibility study of PTCY at 50 mg/kg on day 3 for children with advanced leukemias or malignant solid tumors: refractory to chemotherapy or relapsed after conventional allogeneic HSCT. Conditioning consisted of fludarabine (180 mg/m²) and melphalan (140–210 mg/m²). Results. Long-term engraftments were achieved in 11 patients (73.3%) after bone marrow transplantation (BMT, n = 13) or peripheral blood (PB) stem cell transplantation (n = 2). The incidence of severe acute GHVD was 25.0% and that of extensive chronic GVHD 0.0% after evaluable BMT. CR was achieved in 6/15 and partial response in 4/15 as the best response. Finally, 11/15 experienced disease progression/relapse, 2/15 suffered treatment-related mortality without evidence of disease, and 2/15 are alive in continuous CR. Conclusions. PTCY is feasible in children; however, for a better outcome in such patients with advanced malignancies, some modifications are anticipated.     

Chronic Outpatient Sildenafil Therapy for Pulmonary Hypertension in a Child After Cardiac Surgery

We report the case of a 14-month-old male with d-transposition of the great arteries, ventricular septal defect, and pulmonary hypertension successfully treated with long-term sildenafil following cardiac surgery. To our knowledge, this is the first published report of long-term sildenafil treatment in a child after corrective cardiac surgery.     

Depression in the School-Aged Child With Type 1 Diabetes: Implications for Pediatric Primary Care Providers

Depression is a common comorbid condition experienced by children with type 1 diabetes that, if undiagnosed, can lead to deterioration in glycemic control and other serious health complications. Although it is documented that children with type 1 diabetes experience high rates of depression, a comprehensive clinical guide does not exist to help direct the pediatric provider on how to best care for these children. The purpose of this article is to synthesize current evidence to aid the pediatric primary care provider in the detection and management of depression in the school-aged child with type 1 diabetes.     

Agreement Between Parent Proxy Report and Child Self-Report of Pain Intensity and Health-Related Quality of Life After Surgery

Objectives

Monitoring patient-centered health outcomes after hospital discharge is important for identifying patients experiencing poor recovery after surgery. Utilizing parent reports may improve the feasibility of monitoring recovery when children are not available to provide self-report. We therefore aimed to examine agreement between parent and child reports of child pain and health-related quality of life (HRQOL) in children after hospital discharge from inpatient surgery.

Association of Picky Eating With Weight Status and Dietary Quality Among Low-Income Preschoolers

Background

Picky eating is common in children. Few studies have examined predictors of picky eating, and the association of picky eating with weight status and dietary quality is inconsistent in the literature. We aimed to identify predictors of picky eating and to test the association of picky eating with child body mass index z-score (BMIz), dietary quality, and micronutrient intake.

Acute Renal Insufficiency and Renal Replacement Therapy After Pediatric Cardiopulmonary Bypass Surgery

The aim of the study was to investigate renal function and renal replacement therapy after cardiopulmonary bypass surgery in children. Patient characteristics (sex, age, diagnosis), operation type, and death were listed. The study was performed retrospectively using serum creatinine level before, and peak values after, cardiopulmonary bypass surgery for assessment of renal function. Of the children on renal replacement therapy, indication, efficacy, and complications were recorded. In a 5-year period, 1075 children had cardiopulmonary bypass surgery at the Department of Cardiothoracic Surgery at Leiden University Medical Center and Academic Medical Center of Amsterdam. One-hundred eighty (17%) patients developed acute renal insufficiency. Twenty-five (2.3%) patients required renal replacement therapy. Peritoneal dialysis is a safe and effective treatment for children after cardiopulmonary bypass surgery. However, 15 (60%) of 25 children on renal replacement therapy died of nonrenal causes. In 9 out of 10 surviving children, renal function was normal at time of discharge from hospital. Acute renal insufficiency is a frequent complication after open-heart surgery, although renal replacement therapy was infrequently necessary. Peritoneal dialysis is a safe and effective therapeutic measure for children after cardiac bypass surgery.     

Nasal Mask Bilevel Positive Airway Pressure Ventilation for Diaphragmatic Paralysis After Pediatric Open-Heart Surgery

A 2-year-old boy underwent surgical repair of tetralogy of Fallot. Topical cooling of the heart with ice slush was used during the operation. Diaphragmatic paralysis occurred after the operation, inducing severe respiratory distress. To avoid repeated intubation and tracheostomy, the patient was placed on nasal mask bilevel positive airway pressure (BiPAP) ventilation. After ventilatory support with BiPAP for 40 days, the patient recovered spontaneously from the paralysis. No sedation was required during this time. This report illustrates the usefulness of BiPAP for a pediatric patient with diaphragmatic paralysis after cardiac surgery.     

Aortopexy With Preoperative Computed Tomography and Intraoperative Bronchoscopy for Patients With Central Airway Obstruction After Surgery for Congenital Heart Disease: Postoperative Computed Tomography Results and Clinical Outcomes

Bronchoscopy-guided aortopexy is a surgical management option for patients with central airway obstruction after congenital heart surgery. This study aimed to evaluate the usefulness of bronchoscopy-guided aortopexy based on midterm follow-up evaluation with computed tomography (CT) and clinical outcome. From January 2004 to August 2011, bronchoscopy-guided aortopexy was performed for 16 patients (median age 0.5 years, M:F = 10:6) who had central airway obstruction caused by extrinsic compression (13 in the left main bronchus, 2 in the trachea, 1 in the diffuse trachea and bronchus) after congenital heart surgery. The surgical site for aortopexy was determined by the anatomic relationship between the aorta and the compressed bronchus according to preoperative CT and intraoperative bronchoscopy. The median follow-up period was 2.3 years. The ratios of the diameter and area of stenosis at the narrowed point were estimated using pre- and postoperative CT. Almost all the patients (15/16) showed relief of their preoperative symptoms. The median extubation time was 18 h. The stenosis diameter and area ratios significantly improved, as shown by with the immediate postoperative CT (7.7–48.5 %, p = 0.003; 54.8–80.5 %, p = 0.006). Airway stenosis of more than 75 % (p = 0.013), immediate diameter ratio improvement of <50 % (p = 0.015), preoperative severe respiratory insufficiency (p = 0.038), and male sex (p = 0.024) were associated with recurrent minor respiratory susceptibility. Bronchoscopy-guided aortopexy is a safe and reliable surgical management choice for central airway obstruction after congenital heart surgery. Furthermore, airway improvement after aortopexy was maintained during the midterm follow-up evaluation, according to CT measurements.     

Pediatric Hematology and Oncology in Italy: Half a Century of Progress, An Ongoing Search for Improvement

Pediatric hematology and oncology has been a well-organized specialty throughout Italy only since 1974. However, it seemed interesting and fitting to review some of the milestones lying at the base of the development of this field of medicine: the first Italian Children's Hospital created in Florence in the fifteenth century; the first textbook of pediatrics, De Morbis Puerorum, by G. Mercuriale of Bologna; the first hematologic breakthroughs in the seventeenth, eighteenth, and nineteenth centuries; and the paramount achievements in pediatric hematology and oncology over the last 50 years.     

The Association of Adverse Childhood Experiences With Anxiety and Depression for Children and Youth, 8 to 17 Years of Age

ObjectiveTo determine the prevalence of anxiety and depression and examine their association with adverse childhood experiences (ACEs) among children and adolescents ages 8 to 17 years old.MethodsUsing data from the 2016-2017 National Survey of Children's Health, we conducted a cross-sectional study design with a total sample of 39,929. Our exposure and outcome variables included caregiver report of 9 ACE exposures and current anxiety or current depression. Survey sampling weights and SAS survey procedures were implemented to produce nationally representative results.ResultsOur study found that 9% of children had current anxiety while 4% had current depression. Multivariate analysis concluded that all ACE measures were associated with significantly higher odds of both anxiety and depression. Children exposed to 4 or more ACEs had higher odds of anxiety (adjusted odds ratio [aOR] = 1.7; 95% confidence interval [CI], 1.4–2.1) and depression (aOR = 2.2; 95% CI, 1.7–2.9) than children with exposure to fewer than four ACEs. Assessment of the outcomes of anxiety and depression separately showed differential impacts of ACE exposures as associations were stronger with depression for almost all ACE categories.ConclusionsOur study demonstrates a differential association between ACEs and anxiety and depression. This highlights the importance of assessing the impact of ACEs on internalizing behaviors separately. These findings are significant for pediatric providers as diagnosis and treatment for mental health disorders are vital components of pediatric care and further support the American Academy of Pediatrics' recommendation to screen for ACEs.     

Blood Lactate Levels Differ Significantly Between Surviving and Nonsurviving Patients Within the Same Risk-Adjusted Classification for Congenital Heart Surgery (RACHS-1) Group After Pediatric Cardiac Surgery

This study aimed to examine the association between lactate levels in the first hours after surgery for congenital heart defects and the results of Risk-Adjusted Classification for Congenital Heart Surgery (RACHS-1) scoring and to evaluate serial lactate levels over time to determine whether they can serve as a supplementary tool for postoperative assessment within the same RACHS-1 group of patients. A retrospective cohort study was performed using data retrieved from a clinical database of 255 children who had surgery for congenital heart defects between 1999 and 2001 at Sheba Medical Center. Lactate levels were measured postoperatively four times (mg/dL units). The last sample was taken at the end of the surgical procedure, and lactate levels were measured at admission to the pediatrics critical care unit, then 6 and 12 h after admission. The lactate level was measured via arterial blood gases. A total of 27 deaths occurred, yielding a mortality rate of 7.4% when Norwood operations were excluded and 10.16% when they were included. The mean initial postoperative lactate level was significantly lower for survivors (42.2 ± 32.0 mg/dL) than for nonsurvivors (85.4 ± 54.1 mg/dL) (p < 0.01). The serial mean lactate levels decreased progressively for all surviving patients (r ² = 0.96) compared with nonsurvivors (r ² = 0.02). The lactate levels correlated with the RACHS-1 subgroups at each time point (r ² > 0.96 for all). The Pearson correlations between postoperative lactate levels (last lactate measurement taken in the operating room) and cardiopulmonary bypass (CPB) duration (r = 0.549), clamp duration (r = 0.586), and the inotropic score (r = 0.466) (p < 0.001 for all) were significantly positive. The correlations between the maximum lactate levels (during the first 12 postoperative hours) and CPB duration (r = 0.496), clamp duration (r = 0.509), and the inotropic score (r = 0.633) (p < 0.001 for all) were extremely positive. The early elevation of lactate levels in RACHS-1 subgroups 1 to 3 were highly correlated with poor prognosis and death (p < 0.03). In addition, the lactate levels differed significantly between survivors and nonsurvivors within the same RACHS-1 subgroup. The survivors in RACHS-1 subgroups 1 to 3 had lower mean lactate levels than the nonsurvivors in this group (P = 0.011), and this also held true for the survivors and nonsurvivors in RACHS-1 subgroups 4 to 6 (P = 0.026). Lactate levels differed significantly between survivors and nonsurvivors within the same RACHS-1 subgroup. This combination allows the targeting of appropriately intensive interventions and therapies toward the sickest patients.
