OBJECTIVE: Caregivers of pediatric cancer patients are at risk for posttraumatic stress symptoms (PTSS). Previous literature has identified caregiver illness uncertainty as a predictor of PTSS, yet little is known about the mechanism by which illness uncertainty may affect PTSS. Rumination, or perseverations about the cause and consequences of an event, has been related to posttraumtic stress disorder in other populations. However, limited research of this relationship exists for pediatric cancer caregivers...

Erythema ab igne (EAI) is an asymptomatic dermatosis caused by prolonged exposure to localized heat. Affected areas have net-like hyperpigmentation that may resemble more serious conditions such as livedo racemosa or vasculitis. We report three cases of EAI in pediatric sickle cell disease (SCD) patients who were initially suspected of having a more severe, life-threatening disorder before Dermatology was consulted. Clinicians caring for pediatric SCD patients who regularly use heating pads/devices for pain relief should consider EAI in the differential diagnosis of large areas of net-like hyperpigmentation...

AIM: Frequent cyanotic breath holding spells cause fear and severe anxiety to parents. This study aimed to evaluate clinical, laboratory and treatment characteristics of children with cyanotic breath holding spells. METHODS: Included were 180 children (mean age: 1.82 ± 0.53 years) with cyanotic breath holding spells. They were divided into three groups: with iron deficiency, with iron deficiency anemia and without iron deficiency. Blood hemoglobin (HB), ferritin and iron concentrations were measured at baseline and after 3 and 6 months of iron treatment...

INTRODUCTION: Severe congenital neutropenia (SCN) includes a group of genetic disorders which cause to arrest of neutrophil maturation. SCN can be associated with heterogenous group of genetic defects in ELANE, GFI1, HAX1, G6PC3, JAGN1, VPS45 or activating mutations in the Wiskott-Aldrich syndrome (WAS) gene. AIM: Here we report a patient who has a HAX1 mutation presented with cyclic manner. CASE REPORT: A 6 year old female patients was admitted with recurrent apthous stomatitis...

INTRODUCTION: The aim of this study is to evaluate late side effects that affect quality of life in children with sacrococcygeal teratoma (SCT). PATIENTS AND METHODS: The patients with SCT were evaluated retrospectively. The data were expressed by percentage and the subgroups were compared statistically. RESULTS: A total of 40 children with SCT were identified with median age 12 days (range: 1 day-14.6 years), 27 of whom were analyzed in this study with urodynamic data available for 24 and anal manometric evaluations for 20...

Although the fate of nephrogenic rests varies, they are known to be precursors of Wilms tumour. Thus, nephrogenic rests require adequate treatment to prevent malignant transformation. We added 13-cis retinoic acid to the standard chemotherapy with vincristine and actinomycin-D in two patients with bilateral nephrogenic rests/nephroblastomatosis. Patient 1 also had a history of Wilms tumour. 46 (patient 1) and 81 (patient 2) months after end of treatment, both patients show stable conditions with no signs of relapse or progressive disease...

Li-Fraumeni syndrome is an autosomal dominant cancer syndrome characterized by pathogenic variants in the TP53 gene on chromosome 17. The most common cancers in Li-Fraumeni kindreds include sarcomas, breast cancer, brain tumors, and adrenocortical carcinoma. We report a 9-month-old male who was diagnosed with an adrenocortical tumor and later found to harbor a novel TP53 c.559 G > C germline variant, resulting in p.Gly187Arg. Family history included early-onset breast cancer in his paternal grandmother and paternal great-grandfather, as well as colon cancer at age 31 in a paternal cousin...

Wilms tumor (WT) has a survival rate above 90% in high income countries. Reported survival rates in sub-Saharan Africa are much lower and long-term outcome is not well known as follow-up is challenging. In Blantyre, Malawi, an adapted WT treatment guideline with preoperative chemotherapy, supportive care, and strategies to enable children and parents to complete treatment was introduced in 2006. Between 2006 and 2011, 73 children with a unilateral WT were treated. Follow-up, including home visits when needed, was done...

AIM: Little data is available on long-term renal impairment in survivors from childhood sarcoma. We investigated the prevalence of renal impairment and hypertension after very long-term follow-up in survivors who reached adulthood after treatment for childhood sarcoma. METHODS: A cross-sectional single center study was performed. Outcomes included estimating glomerular filtration rate (eGFR), albuminuria, glycosuria, serum phosphate and magnesium, tubular reabsorption phosphate (TRP), chronic kidney disease (CKD) according to the "Kidney Disease: Improving Global Outcomes" (KDIGO) guidelines and blood pressure (BP)...

The aim of the study was to investigate the expression and methylation status of seven distinctive genes with tumor suppressing properties in childhood and adolescent lymphomas. A total of 96 patients with Hodgkin Lymphoma (HL, n = 41), Non-Hodgkin Lymphoma (NHL, n = 15), and reactive lymphoid hyperplasia (RLH, n = 40, as controls) are included in the research. The expression status of CDKN2A, SPI1, PRDX2, DLEC1, FOXO1, KLF4 and DAPK1 genes were measured with QPCR method after the RNA isolation from paraffin blocks of tumor tissue and cDNA conversion...

The Inaugural Symposium on Childhood Cancer Health Disparities was held in Houston, Texas, on November 2, 2016. The symposium was attended by 109 scientists and clinicians from diverse disciplinary backgrounds with interests in pediatric cancer disparities and focused on reviewing our current knowledge of disparities in cancer risk and outcomes for select childhood cancers. Following a full day of topical sessions, everyone participated in a brainstorming session to develop a working strategy for the continued expansion of research in this area...

Chromogranin A (CgA) and neuron specific enolase (NSE) are important markers in adult neuroendocrine tumors (NET). Neuroblastoma (NB) has certain neuroendocrine properties. The aim of this study was to correlate blood concentrations of CgA, chromogranin B (CgB), and NSE to prognostic factors and outcome in children with NB. Blood samples from 92 patients with NB, 12 patients with benign ganglioneuroma (GN), 21 patients with non-NB solid tumors, 10 patients with acute leukemias, and 69 healthy children, were analyzed...

Primary bone marrow lymphoma (PBML) is hard to diagnose in children, due to the difficult identification of malignant cells in bone marrow. The first case, a 5-year-old boy, showed knee swelling with an intermittent fever. The second case, a 12-year-old girl, showed fever of unknown origin without lymphadenopathy or hepatosplenomegaly. In both cases, the diagnosis was not confirmed despite the repeated bone marrow aspirations. Finally, bone marrow aspiration and biopsy at the positive site by positron emission tomography (PET)-CT contributed to definitive diagnosis of PBML...

OBJECTIVE: To investigate the cardiotoxicity indexes in children with malignant tumors after the administration of anthracycline (ANT) chemotherapy. MATERIALS AND METHODS: Data from 131 children with malignant tumors who were treated using ANT chemotherapy at our hospital from January 2011 to December 2015 were collected to analyze the serologic indexes (such as N-terminal pro-brain natriuretic peptide [NT-proBNP] and isoenzyme of creatine kinase [CK-MB]) and changes in corrected QT interval(QT-c) and left ventricular ejection fraction (LVEF) before and after treatment with different ANT cumulative doses...

BACKGROUND: Parent-reported attention problems have been associated with social functioning in a broad sample of pediatric cancer survivors. OBJECTIVE: The present study focused on a more homogeneous sample (pediatric medulloblastoma survivors), with the novel inclusion of self-reported attention ratings. PARTICIPANTS/METHODS: Thirty-three pediatric medulloblastoma survivors, ages 7-18 years, completed a brief IQ measure and self-report of attentional and social functioning...

Glycogen storage disease (GSD) type 1 is a rare autosomal recessive inherited condition. The 1b subtype comprises the minority of cases, with an estimated prevalence of 1 in 500,000 children. Patients with glycogen storage disease type 1b are often treated with granulocyte colony stimulating factor (G-CSF) for prolonged periods to improve symptoms of inflammatory bowel disease (IBD) and in the face of severe neutropenia to decrease risk of infection. Long-term G-CSF treatment may result in an increased risk of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) possibly due to increased marrow stress resulting in telomere shortening...
