ABSTRACT
Objective: Neuroblastoma is one of the common tumors of childhood. The demonstration of new factors such as isocitrate dehydrogenase 1 (IDH1) and isocitrate dehydrogenase 2 (IDH2) mutations will be important in the diagnosis and treatment. IDH1 and IDH2 mutations have been found in many types of cancer, such as malignant gliomas, acute myeloid leukemias, chondrosarcoma, and thyroid carcinoma. This study aimed to investigate the presence of IDH1 or IDH2 mutations in patients with neuroblastoma and to determine whether these mutations were different in terms of age, clinical findings, and response to treatment. Methods: Biopsy specimens of 25 patients with pediatric neuroblastoma patients were evaluated for IDH mutations. The clinical and laboratory features of the patients with/without mutation were retrospectively analyzed from a hospital database. Results: A total of 25 patients for whom genetic analysis could be performed were included in the study (60% male, n=15). The mean age was 32.2±25.9 months (3 days-96 months). IDH1 mutation was detected in 8 (32%) and IDH2 mutations in 5 (20%) patients. These mutations showed no statistically significant relationship with age, tumor localization, laboratory results, stage, and prognosis. However, in the case of IDH mutation, patients were diagnosed at the advanced stage. Conclusions: This study demonstrated the relationship between neuroblastoma and IDH mutation for the first time. Because to the fact that the mutation is very heterogeneous, it would be appropriate to conduct a larger series of patients in terms of the impact of the clinical significance of each mutation on the diagnosis and prognosis.
ABSTRACT
BACKGROUND: In patients with acute lymphoblastic leukemia (ALL), the risk of thromboembolism increases due to hemostatic changes secondary to the primary disease and due to treatment-related factors. In this multicenter study, we aimed to research the frequency of central nervous system (CNS) thrombosis occurring during treatment, hereditary and acquired risk factors, clinical and laboratory features of patients with thrombosis, treatment approaches, and thrombosis-related mortality and morbidity rates in pediatric ALL patients. PROCEDURE: Pediatric patients who developed CNS thrombosis during ALL treatment from 2010 to 2021 were analyzed retrospectively in 25 different Pediatric Hematology Oncology centers in Türkiye. The demographic characteristics of the patients, symptoms associated with thrombosis, the stage of the leukemia treatment during thrombosis, the anticoagulant therapy applied for thrombosis, and the final status of the patients recorded through electronic medical records were determined. RESULTS: Data from 70 patients with CNS thrombosis during treatment, out of 3968 pediatric patients with ALL, were reviewed. The incidence of CNS thrombosis was 1.8% (venous: 1.5 %; arterial: 0.03%). Among patients with CNS thrombosis, 47 had the event in the first 2 months. Low molecular weight heparin (LMWH) was the most commonly used treatment with a median of 6 months (min-max: 3-28 months). No treatment-related complications occurred. Chronic thrombosis findings occurred in four patients (6%). In five (7%) patients who developed cerebral vein thrombosis, neurological sequelae (epilepsy and neurological deficit) remained. One patient died related to thrombosis, and the mortality rate was 1.4%. CONCLUSION: Cerebral venous thrombosis and, less frequently, cerebral arterial thrombosis may develop in patients with ALL. The incidence of CNS thrombosis is higher during induction therapy than during other courses of treatment. Therefore, patients receiving induction therapy should be monitored carefully for clinical findings suggestive of CNS thrombosis.

BACKGROUND: Heavy menstrual bleeding (HMB) is a common condition in adolescents. However, bleeding disorders are known to be one of the causes of HMB in adolescent girls, so they should be considered. Simple methods that can be used in primary health care are needed to determine whether patients have bleeding disorders. The aim of this study was to evaluate the bleeding score of patients admitted with HMB and to determine the diagnostic value of patients who were symptomatic but whose initial hemostatic tests were normal. METHODS: A total of 113 adolescents with HMB and 20 healthy adolescent girls were included in the study. The Pediatric Bleeding Questionnaire (PBQ) and the International Society of Thrombosis Haemostasis-Bleeding Assessment Tool (ISTH-BAT) were used for evaluation. RESULTS: Overall, approximately 18% (n= 20) of the adolescents in the study were diagnosed with a bleeding disorder. The cut off value for the `clinically significant bleeding score` was found to be 3.5. CONCLUSIONS: The PBQ and ISTH-BAT can help distinguish a significant bleeding history from an otherwise trivial bleeding and can be included in the algorithm for the primary care of adolescents with HMB with suspected bleeding disorders.

BACKGROUND: This study aimed to evaluate the etiology and prognosis of patients followed up for pediatric acute arterial ischemic stroke. METHODS: The clinical characteristics and etiology of patients aged 1 month-18 years who had acute arterial ischemic stroke between January 2010 and December 2020 were retrospectively evaluated. At last follow-up, the patients` functionality (Barthel Index, Functional Independence Measure), quality of life (SF-36 questionnaire), and motor outcomes (Gross Motor Function Classification System) were recorded prospectively/crosssectionally. RESULTS: Forty children (25 boys) with a median current age of 112.5 months (range: 3.6-294) were included in the study. The most frequent etiology was prothrombotic disorders, and the most important factor associated with long-term mortality was valvular heart disease. Of the 27 (67.5%) surviving patients, 29.6% had positive motor outcomes and 29.6% were independent according to the Barthel Index. In terms of quality of life, SF-36 scores were highest in the pain scale and lowest in emotional role difficulty. CONCLUSIONS: Determining the etiology and evaluating prognosis are important to plan effective treatment and rehabilitation for pediatric acute arterial ischemic stroke.

OBJECTIVE: This study aims to reveal the oxidant and antioxidant status in nurses with chemotheropathic drug exposure and radiology unit workers exposed to ionizing radiation (IR). METHODS: Nineteen radiology unit workers, 14 nurses, and 15 controls were included the study. All of the participants using antioxidants, vitamin supplements, smokers, any therapeutic drugs, and exposed therapeutic or diagnostic X-ray or chemotherapeutic drugs in 12 months were excluded from the study. Total and native thiols, disulfide/native thiol percent ratios (SS/SH), disulfide/total thiol percent ratios, disulfide amounts, and native thiol/total thiol percent ratios, ischemia-modified albumin (IMA) were determined. RESULTS: Disulfide levels, disulfide/total thiol ratio, and disulfide/native thiol ratio of serum samples of both radiology unit workers and nurses were significantly higher and ratio of native thiol/total thiol was lower than the control group. The radiation dose in radiology unit workers was mean±SD: 0.02±0.009, median (min-max): 0.02 (0.001-0.04). Thiol-disulfide homeostasis was disturbed and the balance shifted in the direction of oxidant damage, even at low-dose IR exposure and normal range. CONCLUSION: As far as we know, the current findings first demonstrate an apparent chronic oxidative stress in the subjects who were occupationally exposed to antineoplastic drugs and radiation even if annual radiation exposure dose measurements are normal.
ABSTRACT
Intramuscular vitamin K injection is recommended for all newborns to prevent bleeding. However, the number of parents who reject vitamin K is at an increase. We present a 1-month girl who presented with haemorrhagic shock due to extraordinary intra-thoracic bleeding. The patient was treated with thoracentesis and blood transfusion. Parents were informed the about the benefits of Vitamin K and they were convinced to continue a routine immunization programme.

Severe acute respiratory syndrome, coronavirus (SARS, COVID-19) has been declared a pandemic by the World Health Organization since March 2020. Patients with active cancer should be considered especially for priority access to the COVID-19 vaccine. Therefore, our study aimed to learn parents' opinions of cancer-diagnosed patients about the COVID-19 vaccine. Between December 2021 and January 2022, 76 people were willing to answer the questionnaire from the parents of outpatient/inpatient patients at the Pediatric Hematology and Oncology Clinic of Dr. Sami Ulus Obstetrics, Child Health and Diseases Education Research Hospital were included. In our study, 18 parents (23.7%) did not get vaccinated. Among the reasons for not getting vaccinated, the most common answer for "I fear from the vaccine's side effects.", "Do you think oncology patients are at risk for COVID-19?", "Do you think the COVID-19 pandemic affects cancer treatment?" were 90.7%, 89.5% and 21% yes, respectively. Would your opinion of the vaccine be positive if the domestic vaccine was produced?"-67.4% answered yes. Vaccine hesitation and public misinformation put cancer patients at risk. Increasing awareness of the rejection of COVID-19 vaccines is important for public health and the fight against the pandemic. In addition, the doctors' recommendations for conducting oncology treatment will significantly impact parents' compliance with the COVID-19 vaccine.

Glucose 6 phosphate dehydrogenase (G6PD) is expressed in all tissues and is necessary to maintain oxidant stress capacity of cells. G6PD deficiency is the most common enzymopathy in humans and is among the important causes of hemolytic anemia. It has been reported that severe hemolytic anemia due to G6PD deficiency may develop in newly diagnosed diabetes, especially during the correction of hyperglycemia. To date, nine cases have been published. Genetic analysis was not performed for G6PD deficiency in these published patients. We present a case of hemolytic anemia due to G6PD deficiency secondary to newly diagnosed type 1 diabetes mellitus. Genetic testing was performed for the index patient and revealed a previously reported missense pathogenic variant (c.653C>T; p.Ser218Phe) in the G6PD gene.

BACKGROUND: Kawasaki disease (KD) may cause cardiac and coronary complications. Since definite markers to accurately predict coronary involvement is not present, we aimed to analyze the role of hematological indices [neutrophil-to lymphocyte ratio (NLR), platelet-to lymphocyte ratio (PLR), lymphocyte-to monocyte ratio (LMR), and mean platelet volume (MPV)-to lymphocyte ratio (MPVLR)], prognostic nutritional index (PNI) and systemic immune-inflammation index (SII) in predicting coronary involvement of KD. Patients The medical records of 134 KD patients admitted between January 2008 and December 2019 were investigated. Also, 268 age-matched healthy controls (HCs) were included in the study. METHODS: KD patients were divided into two groups: KD with coronary artery lesions (KD-CALs) and KD without CALs. Logistic regression analysis was performed to determine parameters that may predict coronary involvement in children with KD. RESULTS: Among KD patients, 39 (29.1%) had CALs. When compared with HCs, the median levels of WBC, neutrophils, monocytes, eosinophils, platelets, MPV and, the values of NLR, PLR, MPVLR, SII were significantly higher; whereas lymphocyte count, PNI, platelet distribution width (PDW), LMR were markedly lower in the KD group (pË0.001 for all, except for p=0.010 for eosinophil count). The CALs group's SII, PLR, and PNI values were significantly lower than those without (p=0.030, p=0.032, and p Ë0.001; respectively). Multivariable regression analysis revealed that PNI, SII, and gender (male) were associated with CALs in KD. CONCLUSION: Our analysis revealed that male sex, lower PNI, and lower SII levels were independently associated with CALs in children with KD.

In children with ß-thalassemia (ß-thal) trait, tissue damage occurs with oxidative stress due to oxygen free radicals and reactive oxygen species (ROS) production. Dynamic thiol-disulfide homeostasis (DTDH) is one of the most important indicators showing the pro-oxidant/antioxidant status in the body. In this study, we aimed to examine the status of DTDH by measuring native thiol, disulfide, and total thiol levels in children with ß-thal trait. The study included 40 children with ß-thal trait and 30 healthy controls (matched by age and gender). The DTDH parameters were measured by an automated method and results were compared between the groups. The levels of native thiol, total thiol, and disulfide in children with ß-thal trait group were statistically significantly higher than the control group (p < 0.001). There was no significant difference in disulfide/native thiol, disulfide/total thiol, and native thiol/total thiol levels between the groups. In addition, there was no correlation between hemoglobin (Hb) and serum ferritin levels with the markers of DTDH in children with ß-thal trait. In our study, a significant increase was found in native thiol, total thiol, and disulfide levels in response to oxidative stress in children with ß-thal trait compared to the healthy control group. Disulfide levels of the children with ß-thal trait were higher than the control group, showing oxidative stress is high in ß-thal trait. Accordingly, it increases the native thiol and total thiol capacity as compensation.

BACKGROUND: Human brucellosis is one of the most widespread zoonotic diseases that are presented with predominantly hematological manifestations. We aimed to evaluate the hematological findings of childhood brucellosis and to determine the predictive clinical findings and laboratory tests that might be related to hematologic involvement. METHODS: We retrospectively analyzed the medical records of children with brucellosis between 1 January 2005 and 31 December 2018. We compared predictive clinical and physical examination findings and laboratory tests in patients with and without hematological involvement. RESULTS: A total of 212 patients (127 boys (59.9%)) with a mean age of 9.4±4.7 years were evaluated in this study. Blood cultures were performed in 161 (75.9%) patients and Brucella spp were isolated in 70 (43.4%) of them. Ninety-two (43.4%) patients had hematological involvement at least in one series. Anemia was detected in 66 (31.7%) patients, leukopenia in 22 (10.6%) and thrombocytopenia in 10 (4.8%). Four patients (1.9%) had pancytopenia. Age distrubutions of the patients with and without hematological involvement were similar (p=0.6). In patients presented with fever, hepatomegaly and splenomegaly, hematologic involvement was significantly higher (p < 0.05). Hematological involvement was higher in patients who had elevated aspartate aminotransferase and alanine aminotransferase concentrations (p < 0.05). Hematological involvement was higher in patients with positive blood culture (p=0.005). Six patients (2.8%) were treated with intravenous immunoglobulin at 1000 mg/kg/day for two days in addition to anti-brucellosis treatment. CONCLUSIONS: Hematological involvement in brucellosis is a common finding regardless of age, especially in febrile, bacteremic patients and in patients who had hepatosplenomegaly and elevated liver enzymes. Anemia is the most common hematological abnormality.

BACKGROUND: Anthracycline chemotherapy is used to treat a variety of cancers. However, late cardiac effects of anthracycline chemotherapy, such as subclinical left ventricular dilatation and/or dysfunction, have been observed in more than half of long-term survivors of childhood cancers. A major risk factor for anthracycline cardiotoxicity is intrauterine growth restriction (IUGR). We assessed the significance of IUGR as an important risk factor for late cardiotoxic effects of anthracycline therapy in asymptomatic long-term survivors of childhood cancers. MATERIALS AND METHODS: The study included 61 survivors of childhood cancers. Cardiac functions were prospectively studied using both conventional and non-conventional echocardiographic methods (two-dimensional speckle tracking echocardiography) after completion of the treatment. The patients were divided into two groups based on their birth weights: Group 1 (patients with IUGR) and Group 2 (patients with normal birth weight). RESULTS: Conventional echocardiography revealed a similar and normal range of left ventricle systolic and diastolic functions in both groups. However, global longitudinal and circumferential strain values demonstrated subclinical left ventricular systolic dysfunction in both groups as compared with normal reference strain values. Furthermore, Group 1 patients had significantly lower global longitudinal and circumferential strain and strain rate values than those in Group 2 patients. CONCLUSION: Asymptomatic long-term survivors of childhood cancers with a history of IUGR may have an increased risk of anthracycline cardiotoxicity due to the low content of mitochondrial DNA (mtDNA). IUGR is a risk factor for late anthracycline cardiotoxicity.

Thrombotic thrombocytopenic purpura (TTP) is a rare, dangerous, life-threatening disease characterized by microangiopathic hemolytic anemia and thrombocytopenia, along with organ dysfunction due to microangiopathy-related ischemia. Plasma exchange and steroids are used for initial treatment, and rituximab is often used in refractive patients. Caplacizumab, cyclophosphamide, and splenectomy are among other treatment options. It has been reported that bortezomib, a proteasome inhibitor, can be used in the management of refractory acquired TTP. Herein, we present a 16-year-old female patient who was monitored for acquired TTP and treated with high-dose steroids, plasma exchange, rituximab, cyclophosphamide, and N-acetylcysteine but developed renal, cardiac, gastrointestinal, and neurologic complications. The girl was then successfully treated with bortezomib, and she has been monitored in remission for 6 months. We consider that bortezomib is a beneficial treatment, especially in patients with refractory TTP.

BACKGROUND: Renal dysfunction is an underestimated complication of thalassemia major. OBJECTIVES: The aim of this study is to compare the glomerular and tubular functions in children with ß- Thalassemia major (ß- TM) with healthy controls and assess the oxidative stress caused by high ferritin levels. DESIGN AND SETTING: This prospective cross-sectional study was conducted in tertiary care hospital. METHODS: Complete blood count (CBC), calcium (Ca), urea, creatinine (Cr), serum cystatin C before transfusion and urinary calcium (uCa), creatinine (uCr), protein (UPr) levels were analyzed in fresh samples. Beta-2-microglobulin (uß2-MG), N- acetylglucosaminidase (uNAG), retinol binding protein (uRBP), malonedialdehyde (uMDA) secretion and creatinine levels were analyzed. Serum total antioxidant capacity (sTAC) and total oxidant capacity (sTOC) were measured with colorimetric micro-ELISA method. Last four serum ferritin values were recorded and the mean value was used for statistical analyzes. RESULTS: Data from 47 patients and 32 controls were analyzed. The urinary RBP/Cr, Ca/Cr and Protein/Cr, were significantly higher in ß-TM group. A statistically insignificant increase in urinary ß2MG/Cr, uNAG/Cr, MDA/Cr was also found in the TM group. Proteinuria was present in 46 % (n: 22) and hypercalciuria in 34 % (n: 16) of the patients with ß- TM. Serum total antioxidant capacity and total oxidant status (TOS) levels were significantly elevated in the patient group. Serum ferritin was significantly correlated with proteinuria, cystatin C levels, urinary Protein/Cr and uRBP/Cr. CONCLUSION: Asymptomatic renal dysfunction is prevalent in ß- TM patients that necessitate regular screening. Urinary RBP may be useful for early diagnosis.

CHLAMYDOPHILA PNEUMONIAE: , a common cause of respiratory tract infections, rarely leads to serious conditions. A 13-year-old boy with serologically confirmed C. pneumoniae infection presented with pneumonia complicated by pericardial and bilateral pleural effusions. He had a large haemorrhagic pericardial effusion from which 1000 ml of fluid was aspirated over 10 days and a right haemorrhagic pleural effusion which required a chest drain and the removal of 700 ml over 5 days. The addition of clarithromycin to ceftriaxone appeared to enhance recovery. As far as we are aware, this is the first report in the English literature of massive haemorrhagic pericardial and pleural effusions in children owing to C. pneumoniae infection.

Background/aim: Bacteremia remains an important cause of morbidity and mortality during febrile neutropenia (FN) episodes. We aimed to define the risk factors for bacteremia in febrile neutropenic children with hemato-oncological malignancies. Materials and methods: The records of 150 patients aged ≤18 years who developed FN in hematology and oncology clinics were retrospectively evaluated. Patients with bacteremia were compared to patients with negative blood cultures. Results: The mean age of the patients was 7.5 ± 4.8 years. Leukemia was more prevalent than solid tumors (61.3% vs. 38.7%). Bacteremia was present in 23.3% of the patients. Coagulase-negative staphylococci were the most frequently isolated microorganism. Leukopenia, severe neutropenia, positive peripheral blood and central line cultures during the previous 3 months, presence of a central line, previous FN episode(s), hypotension, tachycardia, and tachypnea were found to be risk factors for bacteremia. Positive central line cultures during the previous 3 months and presence of previous FN episode(s) were shown to increase bacteremia risk by 2.4-fold and 2.5-fold, respectively. Conclusion: Presence of a bacterial growth in central line cultures during the previous 3 months and presence of any previous FN episode(s) were shown to increase bacteremia risk by 2.4-fold and 2.5-fold, respectively. These factors can predict bacteremia in children with FN.

Güngör A, Yarali N, Fettah A, Ok-Bozkaya I, Özbek N, Kara A. Hereditary spherocytosis: Retrospective evaluation of 65 children. Turk J Pediatr 2018; 60: 264-269. Hereditary spherocytosis (HS) is a common cause of congenital hemolytic anemia in Caucasians and it could be diagnosed at any age. The aim of this study is to examine the demographic characteristics, clinical features and laboratory findings of children with HS and their complications observed during follow up. Sixty-five patients, with hereditary spherocytosis between January 2008 and September 2013, were enrolled into this retrospective study. The age of patients at the time of diagnosis varied between 15 days and 17 years. The median age of patients at diagnosis was 48 months (IQR 2-78). The female/male ratio was 1.1. Forty-seven patients (72.3%) had a family history of HS. The patients were classified according to laboratory findings: 13 of them (20%) were diagnosed as mild HS, 36 (55.4%) as moderate HS and of 16 (24.6%) as severe HS. During follow-up, nine patients (13.8%) experienced an aplastic crisis. Megaloblastic crisis was not observed in any patient. Twenty patients (30.8%) had cholelithiasis. Splenectomy was performed in 20% of patients and the mean age for splenectomy was 8.3 years. Complications such as sepsis or thrombosis were not detected after splenectomy. Hereditary spherocytosis should be kept in mind in patients with anemia, jaundice and splenomegaly and the family history must be questioned. The most common complication was gallstone; even patients without severe hemolysis should be followed intermittently by abdominal ultrasonography in order to control the development of gallstone.
