Adequate nutrient intake should be provided for the cure of children diagnosed with cancer. The aim of this study was to evaluate serum trace elements and vitamins of children with cancer at diagnosis and during treatment. Children with newly diagnosed cancer who were admitted to our center were evaluated for serum selenium, iron, ferritin, C-reactive protein, vitamin B12, folate, and 25-OH vitamin D levels at presentation, and at the third and sixth months of cancer treatment. Forty-two children (male/female: 15/27) with a median age of 8 years (range, 2 to 17) were included in the study. Mean serum B12, folate, and iron levels were within normal ranges, but selenium and 25-OH vitamin D were low at presentation and during the 6-month period. Serum ferritin levels were high in all 3 measures, but they decreased significantly at the sixth month (P=0.04). There was no relation between micronutrient deficiency and sex, or primary disease, or stage, or place of residence of the patient. In conclusion, serum trace element and vitamin deficiencies are common in children with cancer, and there is a need for further studies with larger patient series.

In this study, we aimed to evaluate the incidence, risk factors, causes and clinical management of intracranial haemorrhage (ICH) diagnosed during foetal life or in the first month of life in term neonates with a discussion of the role of haematological risk factors. This study included term neonates (gestational age 37-42 weeks) with ICH diagnosed, treated and followed up in the Neonatal Intensive Care Unit of Hacettepe University, Ankara, Turkey, between January 1994 and January 2014. Medical follow-up was obtained retrospectively from hospital files and prospectively from telephonic interviews and/or clinical visits. During the study period, 16 term neonates were identified as having ICH in our hospital. In six (37.5%) neonates, ICH was diagnosed during foetal life by obstetric ultrasonography, and in 10 (62.5%) neonates, it has been diagnosed after birth. Haemorrhage types included intraventricular haemorrhage (IVH) in eight (50.0%), intraparenchymal haemorrhage in six (37.5%), subarachnoid haemorrhage in one (6.2%) and subdural haemorrhage in one (6.2%) neonate. IVH was the most common (n = 5/6, 83.3%) haemorrhage type among neonates diagnosed during foetal life. Overall, haemorrhage severity was determined as mild in three (18.7%) neonates, moderate in three (18.75%) neonates and severe in 10 (62.5%) neonates. During follow-up, one infant was diagnosed as afibrinogenemia, one diagnosed as infantile spasm, one cystic fibrosis, one orofaciodigital syndrome and the other diagnosed as Friedrich ataxia. Detailed haematological investigation and search for other underlying diseases are very important to identify the reason of ICH in term neonates. Furthermore, early diagnosis, close monitoring and prompt surgical interventions are significant factors to reduce disabilities.

Aim Since the beginning of the Syrian civil war, more than 3.5 million Syrians have been under temporary protection status in Turkey. Because beta‐thalassemia (BT) is a prevalent disorder in the Mediterranean countries, we decided to estimate the prevalence of and make an overview of the demographic, socioeconomic, medical characteristics, and healthcare problems of refugee children with BT. Patients Eighteen Turkish Pediatric Hematology Oncology Centers (PHOC) with 318 refugee children from 235 families participated in the study. The mean age of the patients was 8.1 ± 4.8 years (0.5–21 years). The mean time after immigration to Turkey was 2.5 ± 1.5 years (range, 0.1–7 years). Seventy‐two (22.6%) of them were born and diagnosed with BT in Turkey. On physical examination, 82 patients (26%) were underweight and 121 patients (38%) were stunted. The appearance of a thalassemic face was reported for 207 patients (65.1%). Hepatomegaly and splenomegaly were reported in 217 (68.2%) and 168 (52.8%) patients, respectively. The median ferritin level was 2508 ng/mL (range, 17–21 000 ng/mL) at the first admission, and 2841 ng/mL (range, 26–12 981 ng/mL) at the last visit after two years of follow‐up in a PHOC (P > 0.05). The most frequently encountered mutation was IVSI‐110 (G>A) (31%). Before immigration, only 177 patients (55.6%) reported the use of chelators; after immigration it increased to 268 (84.3%). Conclusion Difficulties in communication, finding a competent translator capable in medical terminology, nonregular use of medications, and insensitivity to prenatal diagnosis were preliminary problems. The current extent of migration poses emerging socioeconomic and humanitarian challenges for refugee patients with BT.

Chronic lymphocytic leukemia/lymphoma (CLL) is an extremely rare disease during childhood. We report a 16-year-old female who presented with lymphadenopathies and she was diagnosed as T cell lymphoblastic lymphoma. Her chemotherapy response was minimal and clinical findings were unusual. Therefore, her biopsy specimen was re-examined and diagnosis was changed to CLL. Chemotherapy protocol including fludarabine, cyclophosphamide, rituximab was administrated and good response was observed. In our patient deletion at 1q21.2 region that includes aryl hydrocarbon receptor nuclear translocator (ARNT) gene was detected via comparative genomic hybridization method. ARNT gene deletion may be a new mutation in chronic lymphocytic leukemia development.

Background: Brain atrophy, abnormal pituitary morphology, corpus callosum, and posterior fossa abnormalities have been described in patients with Fanconi anemia (FA). We aimed to provide an overview of cranial neuroimaging findings and to evaluate the clinical implications in FA patients. Procedure: Cranial magnetic resonance imaging (MRI) studies of 34 patients with FA were retrospectively evaluated, and patients' clinical data were correlated with the imaging findings. Results: The patients' median age was 17.6 (range, 3.9-28) years. At least one pathological brain imaging finding was demonstrated in 22 (65%) patients. These findings included corpus callosum abnormalities and other related supratentorial malformations in nine, pituitary abnormalities in eight, craniovertebral junction and posterior fossa abnormalities in eight, vascular lesions in six, and intracerebral calcifications in two patients. Among the 22 patients who had abnormal cranial MRI findings, six (27%) had mild to moderate intellectual disability (ID), three (14%) had epilepsy, one (5%) had mild hearing loss, and one patient (5%) had hemiplegia. Among these 34 patients, 14 (41%) were transfusion dependent. There was no significant difference between patients with congenital and acquired neuroimaging findings and patients with normal neuroimaging regarding transfusion dependency. Conclusions: Acquired abnormalities in brain tissue, such as white matter intensity changes, white matter T2 hyperintense discrete foci, or infarcts along with congenital abnormalities, were identified in this study. Variable abnormal brain imaging findings in FA patients, although some were not associated with clinical neurological manifestations, suggest that brain imaging could be part of screening in FA.
