    (ELSEVIER SCIENCE INC, 2021-01-01) Hazar, Volkan; Ozturk, Gulyuz; Yalcin, Koray; Uygun, Vedat; Aksoylar, Serap; Kupesiz, A.; Bozkaya, Ikbal Ok; Karagun, Barbaros Sahin; Bozkurt, Ceyhun; Ileri, Talia; Atay, Didem; Kocak, Ulker; Karasu, Gulsun Tezcan; Yesilipek, Akif; Gokce, Muge; Kansoy, Savas; Kintrup, Gulen Tuysuz; Karakukcu, Musa; Okur, Fatma Visal; Ertem, Mehmet; Kaya, Zuhre; Gursel, Orhan; Yaman, Yontem; Ozbek, Namik; Antmen, Bulent; Tufekci, Ozlem; Albayrak, Canan; Aksoy, Basak Adakli; Sezgin, Gulay; Albayrak, Davut; Evim, Melike Sezgin; Zengin, Emine; Pekpak, Esra; Transpl, Turkish Pediat Bone Marrow
    Relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the most frequent cause of post-transplantation mortality. Isolated extramedullary (EM) relapse (iEMR) after HSCT is relatively rare and not well characterized, particularly in pediatric patients. We retrospectively analyzed 1527 consecutive pediatric patients with acute leukemia after allo-HSCT to study the incidence, risk factors, and outcome of iEMR compared with systemic relapse. The 5 -year cumulative incidence of systemic relapse (either bone marrow {[}BM] only or BM combined with EMR) was 24.8\%, and that of iEMR was 5.5\%. The onset of relapse after allo-HSCT was significantly longer in EM sites than in BM sites (7.19 and 5.58 months, respectively

    COVID-19 in pediatric patients undergoing chronic dialysis and kidney transplantation
    (SPRINGER, 2022-01-01) Canpolat, Nur; Yildirim, Zeynep Yuruk; Yildiz, Nurdan; Tasdemir, Mehmet; Goknar, Nilufer; Evrengul, Havva; Gulmez, Ruveyda; Aksu, Bagdagul; Dursun, Hasan; Ozcelik, Gul; Yavascan, Onder; Cicek, Rumeysa Yasemin; Tulpar, Sebahat; Hacihamdioglu, Duygu Ovunc; Nayir, Ahmet; Alpay, Harika
    The study aims to present the incidence of COVID-19 in pediatric patients undergoing renal replacement therapy (RRT) and to compare the severity and outcomes of the disease between the dialysis and kidney transplant (KTx) groups. This multicenter observational study was conducted between 1 April and 31 December 2020 in Istanbul. Members of the Istanbul branch of the Turkish Pediatric Nephrology Association were asked to report all confirmed cases of COVID-19 who were on RRT, as well as the number of prevalent RRT patients under the age of 20. A total of 46 confirmed cases of COVID-19 were reported from 12 centers, of which 17 were dialysis patients, and 29 were KTx recipients. Thus, the incidence rate of COVID-19 was 9.3\% among dialysis patients and 9.2\% among KTx recipients over a 9-month period in Istanbul. Twelve KTx recipients and three dialysis patients were asymptomatic (p = 0.12). Most of the symptomatic patients in both the dialysis and KTx groups had a mild respiratory illness. Only two patients, one in each group, experienced a severe disease course, and only one hemodialysis patient had a critical illness that required mechanical ventilation. In the entire cohort, one hemodialysis patient with multiple comorbidities died. Conclusion: While most cases are asymptomatic or have a mild disease course, pediatric patients undergoing dialysis and a kidney transplant are at increased risk for COVID-19. What is Known: In adult population, both dialysis patients and kidney transplant recipients are at increased risk for severe illness of COVID-19 and have higher mortality rate. Children with kidney transplantation are not at increased risk for COVID-19 and most have mild disease course. Data on children on dialysis are scarce. What is New: Pediatric patients undergoing dialysis and kidney transplantation have an increased risk for COVID-19. Most patients undergoing renal replacement therapy either on dialysis or transplanted develop asymptomatic or mild COVID-19 disease with a favorable outcome.

    Midterm experience with implantable cardioverter-defibrillators in children and young adults(dagger)
    (OXFORD UNIV PRESS, 2010-01-01) Celiker, Alpay; Olgun, Hasim; Karagoz, Tevfik; Ozer, Sema; Ozkutlu, Suheyla; Alehan, Dursun
    This single-centre study was undertaken to review our experience with implantable cardioverter-defibrillator (ICD) implantation in children with relatively different aetiologies. We retrospectively reviewed the records of the paediatric patients who underwent ICD implantation between October 2001 and December 2008. The data of these patients were collected by reviewing the patients' medical records and computerized departmental pacemaker databases. A total of 28 patients who underwent ICD implantation during this period were included in this study. The median age was 12 years and median weight was 32 kg. Most of the patients had ion-channel diseases (n = 13) or cardiomyopathy (n = 11). Devices were implanted for either secondary (n = 22) or primary (n = 6) prevention. The selected ICD generator type was single chamber in 22 patients, dual chamber in 5 patients, and biventricular in 1. Nineteen patients received 122 shocks. Fifteen of 22 patients (68.2\%) from the secondary prevention group and 2 of 6 patients (33.3\%) from the primary prevention group experienced at least one appropriate shock during a median period of 11.3 months (range: 4 days-6.5 years). Forty-two inappropriate shocks were delivered in seven (31.8\%) patients from the secondary prophylaxis group during a median period of 11.3 months. The most important reason for inappropriate shocks was T-wave oversensing. In six patients, lead-related acute or chronic complications occurred. The ICD was safe and effective in interrupting malignant arrhythmias in children and adolescents with a high risk of sudden cardiac death. However, the occurrence of lead complications is significant. The incidence of therapies delivered by the device, with appropriate and inappropriate shocks, was high and interfered with the quality of life. The most important reason for inappropriate shocks was T-wave oversensing. Careful programming is mandatory to reduce the inappropriate shocks.

    Knowledge, attitudes and misconceptions of primary care physicians regarding fever in children: a cross sectional study
    (BMC, 2012-01-01) Demir, Figen; Sekreter, Ozgur
    Background: Fever is an extremely common sign in paediatric patients and the most common cause for a child to be taken to the doctor. The literature indicates that physicians and parents have too many misconceptions and conflicting results about fever management. In this study we aim to identify knowledge, attitudes and misconceptions of primary care physicians regarding fever in children. Methods: This cross-sectional study was conducted in April-May 2010 involving primary care physicians (n=80). The physicians were surveyed using a self-administered questionnaire. Descriptive statistics were used. Results: In our study only 10\% of the physicians knew that a body temperature of above 37.2 degrees C according to an auxiliary measurement is defined as fever. Only 26.2\% of the physicians took into consideration signs and symptoms other than fever to prescribe antipyretics. 85\% of the physicians prescribed antipyretics to control fever or prevent complications of fever especially febrile seizures. Most of the physicians (76.3\%) in this study reported that the height of fever may be used as an indicator for severe bacterial infection. A great majority of physicians (91.3\%) stated that they advised parents to alternate the use of ibuprofen and paracetamol. Conclusions: There were misconceptions about the management and complications of fever. There is a perceived need to improve the recognition, assessment, and management of fever with regards to underlying illnesses in children.

    Understanding sleep problems in children with epilepsy: Associations with quality of life, Attention-Deficit Hyperactivity Disorder and maternal emotional symptoms
    (W B SAUNDERS CO LTD, 2016-01-01) Ekinci, Ozalp; Isik, Ugur; Gunes, Serkan; Ekinci, Nuran
    Purpose: This study aimed to (1) compare sleep problems between children and adolescents with epilepsy and non-epileptic controls, and (2) examine whether there is an association between sleep problems and quality of life, Attention-Deficit Hyperactivity Disorder (ADHD) and mothers' emotional symptoms. Method: Fifty-three patients from a cohort of epilepsy (aged 7-18 years) and 28 controls with minor medical problems (aged 7-18 years) were included. Parents completed Children's Sleep Habits Questionnaire (CSHQ) and Kinder Lebensqualitatsfragebogen: Children's Quality of Life Questionnaire revised (KINDL-R) for patients and controls.Turgay DSM-IV Disruptive Behavior Disorders Rating Scale (T-DSM-IV-S) parent and teacher forms were used to assess ADHD symptoms for patients. Mothers of the patients completed Beck Depression Inventory and State-Trait Anxiety Inventory (STAI). Neurology clinic charts were reviewed for the epilepsy-related variables. Results: Children with epilepsy had a higher CSHQ Total score than the control group. Those with a CSHQ score >56 (which indicates moderate to severe sleep problems) had lower scores on KINDL-R. Parent rated T-DSM-IV-S Total and Hyperactivity-Impulsivity scores, STAI trait and Beck scores were found to be higher in those with a CSHQ score >56. Significant positive correlations were found between CSHQ Total score and T-DSM-IV-S, STAI trait and Beck scores. Binary logistic regression analysis revealed that T-DSM-IV-S Total, Inattention and Hyperactivity-Impulsivity scores were significantly associated with a higher CSHQ Total score. None of the epilepsy-related variables were found to be related with the CSHQ Total score. Conclusion: Among children with epilepsy, sleep problems lead to a poor quality of life. The link between sleep problems and psychiatric symptoms must be conceptualized as a bilateral relationship. ADHD appears to be the strongest predictor of sleep problems.
