    ABSTRACT: Childhood acute lymphoblastic leukemia (ALL), a heterogeneous disease that includes multiple subtypes is defined by cell lineage and chromosome anomalies. Previous genome-wide association studies have reported several ARID5B and IKZF1 single nucleotide polymorphisms (SNPs) associated with the incidence of ALL. High-resolution melting (HRM) analysis is a rapid and convenient technique to detect SNPs; we thereby detected SNPs in ARID5B and IKZF1 genes. We enrolled 79 pediatric ALL patients and 80 healthy controls. Polymorphic variants of IKZF1 (rs6964823, rs4132601, and rs6944602) and ARID5B (rs7073837, rs10740055, and rs7089424) were detected by HRM, and SNPs were analyzed for association with childhood ALL. The distribution of genotype rs7073837 in ARID5B significantly differed between ALL and controls (P=0.046), while those of IKZF1 (rs6964823, rs4132601, and rs6944602) and ARID5B (rs10740055 and rs7089424) did not. We analyzed the association for SNPs with B lineage ALL to find rs7073837 in ARID5B, conferring a higher risk for B lineage ALL (odds ratio, OR=1.70, 95% confidence interval, CI=1.01-2.87, P=0.049). HRM is a practical method to detect SNPs in ARID5B and IKZF1 genes. We found that rs7073837 in ARID5B correlated with a risk for childhood B lineage ALL.

    ABSTRACT: Diabetes mellitus is a major endocrinopathy for patients with thalassemia major. Although diabetes mellitus is multifactorial, iron loading is its primary cause and its management poses a clinical challenge. Detecting the pre-diabetes stage is critical because clinical diabetes can potentially be reversed or prevented. Patients with thalassemia major who received regular blood transfusion therapy from 1994 to 2010 were evaluated for the incidence of diabetes mellitus and glucose dysregulation. The association between patients' clinical, biochemical, and image parameters was also evaluated. The patients with diabetes were significantly older, had higher ferritin levels, a smaller pancreas volume, and lower cardiac T2* magnetic resonance imaging (MRI) values than the patients without diabetes. The pancreas T2* MRI values were higher in the patients without diabetes, but the difference was not statistically significant. The liver iron concentration did not differ between the patients with and without diabetes. The prevalence of hepatitis C infection and hypogonadism was also higher in the patients with diabetes. In the patients without diabetes, the cardiac T2* MRI values were higher in patients with normal fasting glucose levels (P = 0.03), and the homeostasis model assessment of insulin resistance level was associated with hepatitis C infection (P = 0.024, r = 0.32) and hypogonadism (P = 0.034, r = 0.301). Fasting glucose and insulin levels were appropriate screening tools for evaluating glucose dysregulation and complemented the MRI findings. The cardiac T2* and pancreas volumes were significant predictors of diabetes. Pediatr Blood Cancer © 2013 Wiley Periodicals, Inc.

    ABSTRACT: While the outcomes of cardiopulmonary resuscitation (CPR) for pediatric in-hospital cardiac arrest (IHCA) are reported for many regions, none is reported for Asian countries. We report the outcomes of CPR for pediatric IHCA in a tertiary medical center in Taiwan and also identify prognostic factors associated with poor outcome. Data were retrieved retrospectively from 2000 to 2003 and prospectively from 2004 to 2006 from our web-based registry system. We evaluated patients younger than 18 years of age who had IHCA and received CPR. The primary outcome was survival to hospital discharge, and the secondary outcomes were sustained return of spontaneous circulation (ROSC), and favorable neurological outcomes as assessed by pediatric cerebral performance categories (PCPC). We identified 316 patients and the overall hospital survival was 20.9% and 16.1% had favorable neurological outcomes. Sixty-four patients ever supported with ECMO. We further analyzed 252 patients who underwent conventional CPR only and most had cardiac disease (133/252, 52.8%). The second most common preexisting condition was hematologic or oncologic disease (43/252, 17.1%). Of the 252 patients, 153 (60.7%) achieved sustained ROSC, 50 (19.8%) survived to discharge, and 39 patients (15.5%) had favorable neurological outcomes. CPR during off-work hours resulted in inferior chances of reaching sustained ROSC. Multivariate analysis showed that long CPR duration, hematology/oncology patients, and pre-arrest vasoactive drug infusion were significantly associated with decreased hospital survival (p<0.05). Outcomes of CPR for pediatric patients with IHCA in Taiwan were comparable to corresponding reports in Western countries, but more hematology/oncology patients were included. Long CPR duration, hematologic or oncologic underlying diseases, and vasoactive agent infusion prior IHCA were associated with poor outcomes. The concept of palliative care should be proposed to families of terminally ill cancer patients in order to avoid unnecessary patient suffering. Also, establishing a balanced duty system in the future might increase chances of sustained ROSC.

    ABSTRACT: Tracheobronchial compression by cardiovascular structures complicates the course after surgery of congenital heart disease. A 2-month-old boy with ventricular septal defect, pulmonary atresia, and velocardiofacial syndrome had severe left main bronchus obstruction due to external compression by an anomalously oriented ascending aorta. The patient's hypoxemic episodes necessitated extracorporeal membrane oxygenation. We inserted a stent in the left bronchus to open the airway, but the stent was crushed by the anomalous aorta. We later surgically rerouted the aorta and finally restored the patency of the left main bronchus. However, the patient died of fungemia, without being weaned from extracorporeal membrane oxygenation. We conclude that surgery is necessary instead of stent implantation to relieve the external compression of the left bronchus from a vessel with systemic arterial pressure.
