Abstract
OBJECTIVES In congenital hemolytic anemias (CHA), it is not always possible to determine the specific diagnosis by evaluating clinical findings and conventional laboratory tests. The aim of this study is to evaluate the utility of next-generation sequencing (NGS) and clinical-exome-based copy number variant (CNV) analysis in patients with CHA. METHODS One hundred and forty-three CHA cases from 115 unrelated families referred for molecular analysis were enrolled in the study. Molecular analysis was performed using two different clinical exome panels in 130 patients, and whole-exome sequencing in nine patients. Exome-based CNV calling was incorporated into the traditional single-nucleotide variant and small insertion/deletion analysis pipeline for NGS data in 92 cases. In four patients from the same family, the PK Gypsy variant was investigated using long-range polymerase chain reaction. RESULTS Molecular diagnosis was established in 86% of the study group. The most frequently mutated genes were SPTB (31.7%) and PKLR (28.5%). CNV analysis of 92 cases revealed that three patients had different sizes of large deletions in the SPTB and six patients had a deletion in the PKLR. CONCLUSIONS In this study, NGS provided a high molecular diagnostic rate in cases with rare CHA. Analysis of the CNVs contributed to the diagnostic success.

Abstract
INTRODUCTION Recombinant porcine factor VIII (rpFVIII; susoctocog alfa) is predicted to provide functional FVIII activity in patients with congenital haemophilia A with inhibitors (CHAWI). AIMS To evaluate the efficacy and safety of rpFVIII in patients with CHAWI undergoing invasive procedures. METHODS This phase 3, multicentre, single-arm, open-label study (NCT02895945) enrolled males aged 12-75 years with severe/moderately severe CHAWI who required surgical/invasive procedures. Patients received a loading dose of rpFVIII 1-2 h before surgery. The primary outcome was the proportion of all procedures with a 'good' or 'excellent' response (treatment success) on the global haemostatic efficacy assessment score. RESULTS Of the eight dosed patients, five completed the study. Six of seven surgeries (85.7%; 95% confidence interval, 42.1-99.6) achieved treatment success; five were rated 'excellent', one was rated 'good'. Seven surgery-related bleeding episodes occurred in three patients during the study, with none requiring additional surgical intervention. Overall, six of eight patients experienced 17 treatment-emergent adverse events. Three patients developed de novo inhibitors to rpFVIII. Five patients reported anamnestic reactions, three to both human (h) FVIII (i.e., alloantibodies to exogenous FVIII detected with anti-hFVIII assays) and rpFVIII, and two to hFVIII only. Four serious adverse events were considered related to rpFVIII (three anti-rpFVIII antibody positive; one anamnestic reaction to hFVIII and rpFVIII). CONCLUSION Good haemostasis was achieved with rpFVIII during the immediate perioperative period. The study was terminated early because the study sponsor and health authorities determined that the risk of anamnestic reactions outweighs the benefits in this study population.

Abstract
Spondyloenchondrodysplasia (SPENCD) is a rare spondylometaphyseal skeletal dysplasia with characteristic lesions mimicking enchondromatosis and resulting in short stature. A large spectrum of immunologic abnormalities may be seen in SPENCD, including immune deficiencies and autoimmune disorders. SPENCD is caused by loss of tartrate-resistant acid phosphatase activity, due to homozygous mutations in ACP5 , playing a role in nonnucleic-acid-related stimulation/regulation of the type I interferon pathway. In this article, we presented a 19-year-old boy with SPENCD, presenting with recurrent autoimmune hemolytic anemia episodes since he was 5 years old. He had short stature, platyspondyly, metaphyseal changes, intracranial calcification, spastic paraparesis, and mild intellectual disability. He also had recurrent pneumonia attacks. The clinical diagnosis of SPENCD was confirmed by sequencing of the ACP5 gene, and a homozygous c.155A > C (p.K52T) variation was found, which was reported before as pathogenic. In conclusion, in early onset chronic autoimmune cytopenias an immune dysregulation may often have a role in the etiology. Associating findings and immunologic functions should be carefully evaluated in such patients in the light of the literature. The present case shows the importance of multisystemic evaluation for the detection of SPENCD that has a monogenic etiology.

Abstract
BACKGROUND Managing intracranial bleeding in patients with refractory immune thrombocytopenia is difficult. OBSERVATION A 16-year-old female refractory to prednisolone, intravenous immunoglobulin, eltrombopag, and cyclosporin exhibited heavy menstrual bleeding requiring packed red blood cell transfusions. Autoimmune antibodies were detected, indicating of lupus, and hydroxychloroquine sulfate was administered. In month 6 following the diagnosis, the patient presented with intracranial hemorrhage. Splenic artery embolization promptly increased platelets, and the patient was discharged without any neurological sequela. In month 5 of embolization, the patient's platelet count continued to exceed 300,000/µL without any medical treatment. CONCLUSIONS Splenic artery embolization is a life-saving procedure in refractory immune thrombocytopenia.

Abstract
Aging is associated with changes in circulating levels of various molecules, some of which remain undefined. We find that concentrations of circulating taurine decline with aging in mice, monkeys, and humans. A reversal of this decline through taurine supplementation increased the health span (the period of healthy living) and life span in mice and health span in monkeys. Mechanistically, taurine reduced cellular senescence, protected against telomerase deficiency, suppressed mitochondrial dysfunction, decreased DNA damage, and attenuated inflammaging. In humans, lower taurine concentrations correlated with several age-related diseases and taurine concentrations increased after acute endurance exercise. Thus, taurine deficiency may be a driver of aging because its reversal increases health span in worms, rodents, and primates and life span in worms and rodents. Clinical trials in humans seem warranted to test whether taurine deficiency might drive aging in humans.

Abstract
Indications of leukapheresis (LPh) and the prophylactic use of rasburicase in tumor lysis syndrome (TLS) of patients with acute leukemia with hyperleukocytosis are not clear. In this retrospective single-center pediatric study, the outcomes of patients with hyperleukocytosis were reviewed. There were 48 patients with acute lymphoblastic leukemia (ALL) and 13 patients with acute myeloblastic leukemia (AML). The treatment strategies included hyperhydration, allopurinol administration, strict monitoring, and early initiation of induction chemotherapy (CT). No patient underwent LPh because it was not available. Rasburicase was used only in 3 ALL patients with hyperuricemia when the drug was available. Laboratory and clinical TLS developed in 54.16% and 14.58% of patients with ALL, respectively. Laboratory and clinical TLS developed in 76.92% and 15.38% of patients with AML, respectively. No patient developed grade III to V TLS requiring dialysis. Thirteen patients (21.3%) had pulmonary leukostasis on admission, but recovered with CT and nasal oxygen. During the first 14 days of presentation, cerebral leukostasis/coagulopathy-related early death (ED) was 4.2% and 7.7% in patients with ALL and AML, respectively, and all of these patients had a white blood cell count ≥400,000/µL. There was also 1 infection-related death. Patients with hyperleukocytosis can be treated without LPh and liberal use of rasburicase. Renal failure is no longer a cause of ED. Intracranial hemorrhage is the main cause of ED, especially in patients already presenting with this complication. LPh may be performed in patients with leukostasis, if it is not possible to start induction CT early. When resources are limited, rasburicase should be administered in patients presenting with or developing hyperuricemia and/or renal dysfunction.

Abstract
Objective This study aimed to evaluate systemic thrombolysis experiences with recombinant tissue plasminogen activator (rtPA). Materials and Methods Retrospective data were collected from 13 Turkish pediatric hematology centers. The dose and duration of rtPA treatment, concomitant anticoagulant treatment, complete clot resolution (CCR), partial clot resolution (PCR), and bleeding complications were evaluated. Low-dose (LD) rtPA treatment was defined as 0.01-0.06 mg/kg/h and high-dose (HD) rtPA as 0.1-0.5 mg/kg/h. Results Between 2005 and 2019, 55 thrombotic episodes of 54 pediatric patients with a median age of 5 years (range: 1 day to 17.75 years) were evaluated. These patients had intracardiac thrombosis (n=16), deep vein thrombosis (DVT) (n=15), non-stroke arterial thrombosis (n=14), pulmonary thromboembolism (PE) (n=6), and stroke (n=4). The duration from thrombus detection to rtPA initiation was a median of 12 h (range: 2-504 h) and it was significantly longer in cases of DVT and PE compared to stroke, non-stroke arterial thrombosis, and intracardiac thrombosis (p=0.024). In 63.6% of the episodes, heparin was initiated before rtPA treatment. LD and HD rtPA were administered in 22 and 33 of the episodes, respectively. Concomitant anticoagulation was used in 90% and 36% of the episodes with LD and HD rtPA, respectively (p=0.0001). Median total duration of LD and HD rtPA infusions was 30 h (range: 2-120 h) and 18 h (2-120 h), respectively (p=0.044). Non-fatal major and minor bleeding rates were 12.5% and 16.7% for LD and 3.2% and 25.8% for HD rtPA, respectively. At the end of the rtPA infusions, CCR and PCR were achieved in 32.7% and 49.0% of the episodes, respectively. The most successful site for thrombolysis was intracardiac thrombosis. HD versus LD rtPA administration was not correlated with CCR/PCR or bleeding (p>0.05). Conclusion Systemic thrombolytic therapy may save lives and organs effectively if it is used at the right indications and the right times in children with high-risk thrombosis by experienced hematologists with close monitoring of recanalization and bleeding.

Abstract
Although congenital erythrocytosis (CE), an inherited disorder, impairs pediatric quality of life, physicians often overlook high hemoglobin (Hgb) levels and its symptoms due to lack of knowledge of age-adjusted pediatric Hgb levels and CE's rarity. In a retrospective, single-center study, data from hospital records of pediatric patients diagnosed with CE were evaluated. Twenty-six patients from 25 families (80.8% male) had been diagnosed with CE in 20 years, at a mean age of 14.9 ± 2.8 years (8.3-17.8) and with a mean Hgb level of 17.36 ± 1.44 g/dL (14.63-22.1). No serum erythropoietin levels exceeded the reference levels. Although the most common symptom was headache (85%), 38% of patients presented with at least one gastrointestinal symptom (e.g., nausea, vomiting, abdominal pain, and rectal bleeding), and 54% exhibited plethora. No patient had leukocytosis, thrombocytosis, JAK2 mutation; capillary oxygen saturation, venous blood gas analysis, and Hgb electrophoresis revealed no abnormalities. While 34.6% of patients had family histories of CE, 42.3% had 15-45-year-old relatives who had experienced myocardial infarction, stroke, and/or sudden death. Aspirin was routinely prescribed, and phlebotomy was performed when hyperviscosity symptoms were present. To detect CE, physicians should consider age-adjusted normal Hgb levels in children. Pediatric patients with CE may also present with gastrointestinal symptoms. Although no thrombotic episode occurred among the patients, their family histories included life-threatening thrombotic episodes, even in adolescents.

Abstract
Glanzmann thrombasthenia (GT) is a rare autosomal recessive bleeding disorder characterized by impaired platelet aggregation due to defects in integrin αIIbβ3, a fibrinogen receptor. Platelet phenotypes and allelic variations in 28 Turkish GT patients are reported. Platelets αIIbβ3 expression was evaluated by flow cytometry. Sequence analyzes of ITGA2B and ITGB3 genes allowed identifying nine variants. Non-sense variation effect on αIIbβ3 expression was studied by using transfected cell lines. 3D molecular dynamics (MDs) simulations allowed characterizing structural alterations. Five new alleles were described. αIIb:p.Gly423Asp, p.Asp560Ala and p.Tyr784Cys substitutions impaired αIIbβ3 expression. The αIIb:p.Gly128Val substitution allowed normal expression; however, the corresponding NM_000419.3:c.476G>T variation would create a cryptic donor splicing site altering mRNA processing. The β3:p.Gly540Asp substitution allowed αIIbβ3 expression in HEK-293 cells but induced its constitutive activation likely by impairing αIIb and β3 legs interaction. The substitution alters the β3 I-EGF-3 domain flexibility as shown by MDs simulations. GT variations are mostly unique although the NM_000419.3:c.1752 + 2 T > C and NM_000212.2:c.1697 G > A variations identified in 4 and 8 families, respectively, might be a current cause of GT in Turkey. MD simulations suggested how some subtle structural variations in the β3 I-EGF domains might induce constitutive activation of αIIbβ3 without altering the global domain structure.

Abstract
We report isolated extramedullary relapse in a 14-year-old boy, sequentially presenting with intestinal and cardiac myeloid sarcoma (MS). Acute myeloblastic leukemia M5 was diagnosed 41 months ago. On the 14th month of the second HSCT, he presented with ileus and underwent surgical treatment. After 2 weeks, arrhythmia, bradycardia, complete heart block, and atrial flutter developed and echocardiography revealed multiple cardiac masses. There was no bone marrow relapse but pathology of the intestinal biopsy showed leukemic infiltration. Patient was successfully treated with a permanent pacemaker and salvage chemotherapy. To the best of our knowledge, this is the first pediatric cardiac MS developed after HSCT.

Abstract
BACKGROUND AND OBJECTIVES In this retrospective report the aim was to present the experience about bleeding characteristics and management of minor surgeries in rare bleeding disorders (RBDs). METHODS Twenty-six patients were included; with Factor (F) V, FV+VIII, VII, FXI deficiency and afibrinogenemia. Six of the patients were asymptomatic. RESULTS Fifty-three percent of the patients suffered from mucosal bleeding. Life-threatening bleedings were observed only in the patients with afibrinogenemia and good hemostatic control could only be provided with plasma-derived (pd)-fibrinogen concentrate. Twelve of the patients had undergone 17 minor surgeries. In the patients with FVII and FXI deficiencies with plasma F:C activity between 20-47%, there was a history of uneventful tooth extractions, circumcisions and a pilonidal sinus operation performed without any replacement treatment, whereas one patient with plasma F:C activity of FVII 47% had a history of poor hemostatic control during an adeno-tonsillectomy operation. Although some of these patients were asymptomatic to be on the safe side, minor operations were performed with preoperative administration of one dose of (pd)-fibrinogen concentrate to one afibrinogenemia patient, recombinant active FVII (rFVIIa) to 2 FVII deficient patients and fresh frozen plasma (FFP) to 3 FXI deficient and 1 FVII deficient patients plus postoperatively tranexamic acid (TXA) for 5-7 days. Only with one dose of the replacement therapy just before surgeries good hemostatic control was achieved and none of them had bleeding neither during nor after the surgeries. CONCLUSION We suggest that minor operations must be performed with preoperative replacement therapies plus 5-7 days of antifibrinolytics under close observation of the hematologist and the surgeon.

Abstract
INTRODUCTION Congenital afibrinogenemia is a rare autosomal recessive disorder characterized by bleeding that varies from mild to severe and by complete absence or extremely low levels of plasma and platelet fibrinogen. Hypofibrinogenemia is characterized by fibrinogen levels <1.5 g/L. OBJECTIVE In this study, we analyzed fibrinogen beta chain gene mutations in Turkish afibrinogenemia and hypofibrinogenemia patients. METHODS We evaluated 20 afibrinogenemia and hypofibrinogenemia patients and 80 healthy controls. We have sequenced all exons of the FGB gene using the DNA isolated from the peripheral blood samples of patients and controls. RESULTS AND CONCLUSION We found a nonsense mutation in exon 4 at nucleotide 630 that encoded serine amino acid, and in the same exon a missense mutation of T to C at nucleotide 647, resulting in a transition from leucine to proline (p.L198P) in a child with hypofibrinogenemia. These mutations have been shown for the first time in the same patient of Turkish descent. Furthermore, there was a novel heterozygous guanine-to-adenine nucleotide change in exon 3. This caused the change of arginine amino acid to threonine amino acid at position 136 (p.A136T) in a protein, which has not been described in the literature before.

Abstract
Genomic profiles of leukemia patients lead to characterization of variations that provide the molecular classification of risk groups, prediction of clinical outcome and therapeutic decisions. In this study, we examined the diagnostic (n = 77) and relapsed (n = 31) pediatric B-cell acute lymphoblastic leukemia (B-ALL) samples for the most common leukemia-associated gene variations CRLF2, JAK2, PAX5 and IL7R using deep sequencing and copy number alterations (CNAs) (CDKN2A/2B, PAX5, RB1, BTG1, ETV6, CSF2RA, IL3RA and CRLF2) by multiplex ligation proximity assay (MLPA), and evaluated for the clonal changes through relapse. Single nucleotide variations SNVs were detected in 19% of diagnostic 15.3% of relapse samples. The CNAs were detected in 55% of diagnosed patients; most common affected genes were CDKN2A/2B, PAX5, and CRLF2. Relapse samples did not accumulate a greater number of CNAs or SNVs than the cohort of diagnostic samples, but the clonal dynamics showed the accumulation/disappearance of specific gene variations explained the course of relapse. The CDKN2A/2B were most frequently altered in relapse samples and 32% of relapse samples carried at least one CNA. Moreover, CDKN2A/2B alterations and/or JAK2 variations were associated with decreased relapse-free survival. On the other hand, CRLF2 copy number alterations predicted a better survival rate in B-ALL. These findings contribute to the knowledge of CDKN2A/2B and CRLF2 alterations and their prognostic value in B-ALL. The integration of genomic data in clinical practice will enable better stratification of ALL patients and allow deeper understanding of the nature of relapse.

Abstract
OBJECTIVE This study aimed to evaluate infection-related mortality in patients with acute myeloid leukemia (AML) treated without preventive antibiotics and antifungals in a middle-income country. MATERIALS AND METHODS Infection-related mortality was evaluated retrospectively in 49 pediatric patients. RESULTS A total of 173 chemotherapy courses were administered as first-line chemotherapy. Four patients died during induction: one patient due to intracranial bleeding, two patients due to typhlitis, and one patient due to invasive fungal infection with pulmonary vascular invasion and massive bleeding. Another two patients died with resistant disease. During consolidation there were four infection-related deaths and one death due to cardiotoxicity. In first-line chemotherapy mortality was 22% (11/49); infection-related mortality was 14% (7/49). Event-free survival and overall survival at 6 years were 42.9% and 61.2% (95% CI: 44-76 and 66-99 months), respectively. CONCLUSION Due to considerable infection-related deaths, antibacterial and mold-active antifungal prophylaxis may be tried during neutropenic periods in pediatric AML.

Abstract
INTRODUCTION This prospective study was planned to investigate the frequency and relationship of acquired von Willebrand syndrome (AVWS) with aortic and pulmonary stenosis in patients. METHODS A total of 84 children, ranging from two to 18 years of age, were enrolled in this study. Of these, 28 had isolated aortic stenosis, 32 had isolated pulmonary stenosis and 24 were healthy. Children with aortic and pulmonary stenosis associated with other congenital heart diseases were excluded. Children with hypothyroidism, renal or liver disease, malignancy or autoimmune disease were also excluded. Wholeblood count, blood group, factor VIII level, prothrombin time (PT), activated partial thromboplastin time (aPTT), von Willebrand factor antigen (VWF:Ag), ristocetin co-factor (VWF:RCo), and bleeding time using a platelet-function analyser (PFA-100) were performed in all patients. All of the children in the study underwent a detailed physical examination and echocardiographic evaluation. RESULTS A history of bleeding was positive in 18% of the aortic stenosis group, 9% of the pulmonary stenosis group, and 4% of the control group. Seven of 60 (12%) patients had laboratory findings that implied a diagnosis of AVWS, and two of these (28%) had a history of bleeding. The frequency of AVWS was 14% in patients with aortic stenosis and 9% in those with pulmonary stenosis. CONCLUSION AVWS is not rare in stenotic obstructive cardiac diseases. A detailed history of bleeding should be taken from patients with valvular disease. Even if the history is negative, whole blood count, PT and aPTT should be performed. If necessary, PFA-100 closure time and further tests should be planned for the diagnosis of AVWS.

Abstract
OBJECTIVE This study aimed to define the status of juvenile myelomonocytic leukemia (JMML) patients in Turkey in terms of time of diagnosis, clinical characteristics, mutational studies, clinical course, and treatment strategies. MATERIALS AND METHODS Data including clinical and laboratory characteristics and treatment strategies of JMML patients were collected retrospectively from pediatric hematology-oncology centers in Turkey. RESULTS Sixty-five children with JMML diagnosed between 2002 and 2016 in 18 institutions throughout Turkey were enrolled in the study. The median age at diagnosis was 17 months (min-max: 2-117 months). Splenomegaly was present in 92% of patients at the time of diagnosis. The median white blood cell, monocyte, and platelet counts were 32.9x109/L, 5.4x109/L, and 58.3x109/L, respectively. Monosomy 7 was present in 18% of patients. JMML mutational analysis was performed in 32 of 65 patients (49%) and PTPN11 was the most common mutation. Hematopoietic stem cell transplantation (HSCT) could only be performed in 28 patients (44%), the majority being after the year 2012. The most frequent reason for not performing HSCT was the inability to find a suitable donor. The median time from diagnosis to HSCT was 9 months (min-max: 2-63 months). The 5-year cumulative survival rate was 33% and median estimated survival time was 30±17.4 months (95% CI: 0-64.1) for all patients. Survival time was significantly better in the HSCT group (log-rank p=0.019). Older age at diagnosis (>2 years), platelet count of less than 40x109/L, and PTPN11 mutation were the factors significantly associated with shorter survival time. CONCLUSION Although there has recently been improvement in terms of definitive diagnosis and HSCT in JMML patients, the overall results are not satisfactory and it is necessary to put more effort into this issue in Turkey.

Abstract
OBJECTIVE To present and discuss the treatment of autoimmune hemolytic anemia (AIHA). METHODS The medical records of all patients (n=19) diagnosed in a tertiary hematology center between 1999 and 2010 were retrospectively reviewed. RESULTS Median age at diagnosis of AIHA was 5 years (range: 4 months-17 years). In all, 13 patients had primary (idiopathic) AIHA, whereas 2 had primary Evans Syndrome (ES), 2 had autoimmune lymphoproliferative syndrome (ALPS)+ES, and 1 had Wiskott-Aldrich syndrome (WAS)+AIHA. Among the 13 primary idiopathic AIHA patients, 9 recovered following a 4-8-week course of prednisolone treatment without relapses, whereas 3 patients required a longer course of prednisolone. One AIHA patient that was very resistant to prednisolone recovered after cyclosporine A was added to the treatment. All patients with primary idiopathic AIHA were in remission for a median of 3 years (range: 4 months-10 years) at the time this manuscript was written. Among the patients with primary ES, 2 had relapses similar to the ALPS patients. Splenectomy was performed in 1 primary ES patient, who at the time this report was written was also in remission. One ALPS patient required the addition of mycophenolate mofetil due to prednisolone resistance. The WAS patient was treatment resistant and died due to septicemia. CONCLUSION Primary AIHA in pediatric patients generally has an acute onset and good response to corticosteroids. Primary or secondary ES has a chronic or relapsing course, and treatment may require other immunosuppressive agents in addition to corticosteroids. Complications of splenectomy must not be underestimated in patients with underlying immunodeficiency. AIHA often causes considerable morbidity and mortality in WAS.

Abstract
OBJECTIVE The aim of this study is to investigate the efficacy and safety of sedoanalgesia performed outside the operating room by pediatricians trained in advanced airway management and life support. MATERIALS AND METHODS Midazolam and ketamine were administered consecutively by intravenous route under cardiorespiratory monitoring for painful procedures of pediatric hematology. RESULTS A total of 115 patients had 237 sedoanalgesia sessions. Sedation time was 24.02±23.37 s and sedation success was 92.5% (Ramsay scores of ≥5). Patient satisfaction was high. The recovery time was 28.81±14.4 min. Although statistically significant (p<0.01) increases in systolic and diastolic blood pressure, heart rate, and respiratory rate were observed without clinical importance, they improved without any intervention. No severe adverse events were observed. CONCLUSION Sedoanalgesia with intravenous midazolam and ketamine for pediatric hematology and oncology patients' painful minor invasive procedures performed in an optimally equipped setting outside the operating room by pediatricians trained and certificated in advanced airway management and life support is effective and safe.

Abstract
Both maternal and offspring-derived factors contribute to lifelong growth and bone mass accrual, although the specific role of maternal deficiencies in the growth and bone mass of offspring is poorly understood. In the present study, we have shown that vitamin B12 (B12) deficiency in a murine genetic model results in severe postweaning growth retardation and osteoporosis, and the severity and time of onset of this phenotype in the offspring depends on the maternal genotype. Using integrated physiological and metabolomic analysis, we determined that B12 deficiency in the offspring decreases liver taurine production and associates with abrogation of a growth hormone/insulin-like growth factor 1 (GH/IGF1) axis. Taurine increased GH-dependent IGF1 synthesis in the liver, which subsequently enhanced osteoblast function, and in B12-deficient offspring, oral administration of taurine rescued their growth retardation and osteoporosis phenotypes. These results identify B12 as an essential vitamin that positively regulates postweaning growth and bone formation through taurine synthesis and suggests potential therapies to increase bone mass.

Abstract
BACKGROUND Late haemorrhagic disease of the newborn (HDN) can occur owing to a lack of vitamin K prophylaxis, as a manifestation of an underlying disorder or idiopatically from the 8th day to 12 weeks after birth. METHODS Eight infants admitted to Kocaeli University Hospital with nine episodes of late HDN between January 2002 and April 2005 were evaluated retrospectively from hospital records. RESULTS The median age at presentation was 46 (26-111) days. All the infants were born at full-term to healthy mothers and were exclusively breast-fed. All had an uneventful perinatal history, except one who had meconium aspiration. Four patients had received no vitamin K prophylaxis and another three had uncertain histories. At presentation, six had intracranial bleeding and the remainder had bleeding either from the venepuncture site or the gastro-intestinal tract. The presenting signs and symptoms were irritability, vomiting, bulging or full fontanelle, convulsions and diminished or absent neonatal reflexes. Galactosaemia was detected in a 2-month-old infant with prolonged jaundice. There was no surgery-related mortality or complications but one survived for only 2 days on ventilatory support following surgery. Only one of the six survivors had severe neurological sequelae. CONCLUSIONS Late HDN frequently presents with intracranial haemorrhage, leading to high morbidity and mortality. HDN can be the manifestation of an underlying metabolic disorder. Vitamin K prophylaxis of the newborn should be routine in developing countries.

Abstract
OBJECTIVE Chronic menorrhagia causes anemia and impairment of life quality. In this study the aim was the screening of bleeding disorders in adolescents and young women with menorrhagia. MATERIALS AND METHODS The study was performed prospectively by pediatric hematologists. A form including demographic characteristics of the patients, bleedings other than menorrhagia, familial bleeding history, characteristics of the menorrhagia, and impairment of life quality due to menorrhagia was filled out by the researcher during a face-to-face interview with the patient. A pictorial blood assessment chart was also used for evaluation of blood loss. All patients underwent pelvic ultrasound sonography testing and women also received pelvic examination by gynecologists. Whole blood count, peripheral blood smear, blood group, serum transaminases, urea, creatinine, ferritin, PFA-100, PT, aPTT, INR, TT, fibrinogen, VWF:Ag, VWF:RCo, FVIII, and platelet aggregation assays were performed. Platelet aggregations were studied by lumiaggregometer. RESULTS Out of 75 patients enrolled, 60 patients completed the study. The mean age was 20.68±10.34 (range: 10-48) years and 65% (n=39) of the patients were younger than 18 years. In 18 (46%) of the adolescents, menorrhagia subsided spontaneously. In 20% (n=12) of the patients, a bleeding disorder was detected (1 case of type 3 von Willebrand disease, 2 patients with low VWF:Ag, 1 case of probable von Willebrand disease, 3 cases of Bernard-Soulier syndrome, 2 cases of Glanzmann thrombasthenia, 2 cases of immune thrombocytopenic purpura, 1 case of congenital factor VII deficiency). CONCLUSION In patients with menorrhagia, at least complete blood count, peripheral smear, aPTT, PT, VWF:Ag, VWF:RCo, FVIII, and fibrinogen assays must be performed. When there is history of nose and gum bleeding, platelet function assay by lumiaggregometer must also be performed. In nearly 50% of adolescents, menorrhagia is dysfunctional and transient. Detailed coagulation assays can be postponed in adolescents if bleeding history other than menorrhagia and/or family history of bleeding and/or parental consanguinity is absent. All subjects with menorrhagia must consult with gynecologists and hematologists. CONFLICT OF INTEREST None declared.

Abstract
A two-month-old male infant presented with jaundice, pallor, and hepatomegaly. The first child of non-consanguineous parents had also suffered from hemolytic anemia and neuromotor retardation and died at the age of 21 months. The patient required phototherapy and transfusion in the newborn period but hemolysis was mild thereafter. The patient had neuromotor retardation, and at the age of 14 months, ventilatory support was necessary, and the patient lived until 17 months. Triose-phosphate isomerase (TPI) deficiency, which is a rare autosomal recessive multisystem disorder of glycolysis, was detected. There was homozygous missense mutation in the TPI1 gene (p.Glu105Asp). This is the most common mutation with a severe phenotype that requires ventilator support in the second year of life. In patients with hemolysis and neuromotor retardation, TPI deficiency must be considered. There is no specific treatment, but detection of the index case may provide the opportunity for genetic counseling and prenatal diagnosis.

Abstract
OBJECTIVE T-cell acute lymphoblastic leukemia (T-ALL) is associated with recurrent chromosomal aberrations andabnormal ectopic gene expression during T-cell development. In order to gain insight into the pathogenesis of T-ALLthis study aimed to measure the level of expression of 7 T-cell oncogenes (LMO2, LYL1, TAL1, TLX1, TLX3, BMI1, andCALM-AF10) in pediatric T-ALL patients Material and Methods: LMO2, LYL1, TLX1, TLX3, BMI1, TAL1, and CALM-AF10 expression was measured usingquantitative real-time PCR in 43 pediatric T-ALL patients. RESULTS A high level of expression of LMO2, LYL1, TAL1, and BMI1 genes was observed in a large group of T-ALL.Several gene expression signatures indicative of leukemic arrest at specific stages of normal thymocyte development(LYL1 and LMO2) were highly expressed during the cortical and mature stages of T-cell development. Furthermore,upregulated TAL1 and BMI1 expression was observed in all phenotypic subgroups. In all, 6 of the patients had TLX1and TLX3 proto-oncogene expression, which does not occur in normal cells, and none of the patients had CALM-AF10fusion gene transcription. Expression of LYL1 alone and LMO2-LYL1 co-expression were associated with mediastinalinvolvement; however, high-level oncogene expression was not predictive of outcome in the present pediatric T-ALLpatient group, but there was a trend towards a poor prognostic impact of TAL1 and/or LMO2 and/or LYL1 protooncogeneexpression. CONCLUSION Poor prognostic impact of TAL1 and/or LMO2 and/or LYL1 proto-oncogene expression indicate the needfor extensive study on oncogenic rearrangement and immunophenotypic markers in T-ALL, and their relationship totreatment outcome.

Abstract
Objective: To identify the well-known common translocations and FLT3 mutations in childhood acute myelogenousleukemia (AML) patients in Turkey. Material and Methods: The study included 50 newly diagnosed patients in which t(15;17), t(8;21), and inv(16)chromosomal translocations were identified using real-time PCR and FLT3 gene mutations were identified via direct PCR amplification PCR-RE analysis. Results: In all, t(15;17) chromosomal aberrations were observed in 4 patients (8.0%), t(8;21) chromosomal aberrationswere observed in 12 patients (24.0%), inv(16) chromosomal aberrations were observed in 3 patients (6.0%), and FLT3-ITD mutations were observed in 2 patients (4.0%); FLT3-D835 point mutation heterozygosity was observed in only 1patient (2.0%) patient. Conclusion: Despite of the known literature, a patient with FLT3-ITD and FLT3-D835 double mutation shows a bettersurvival and this might be due to the complementation effect of the t(15;17) translocation. The reportedmutation ratein this article (4%) of FLT3 gene seems to be one of the first results for Turkish population.

Abstract
Acute lymphoblastic leukemia (ALL) survivors were screened for risk factors of cardiovascular disease. Forty-four ALL survivors in first remission were enrolled. Twenty-six also received 12-18 Gy cranial radiotherapy (RT). Patients' body mass indexes (BMIs) at dignosis and during the study were compared. Metabolic syndrome (MS) evaluation was performed in patients, parents, and siblings older than 6 years. Homeostasis Model Assessment (HOMA) index of the survivors was also calculated. In survivors with impaired fasting glucose levels, oral glucose tolerance test (OGTT) was performed. Thyroid functions and IGF-1 and/or IGFBP-3 levels of the survivors who received cranial RT were evaluated. Median age of the survivors was 11.5 years (6-23). At diagnosis, mean BMI percentile was 46.7 (3-95) and mean z-score was -0.09 ± 1.14; during the study, these values rose to 71.1 ± 25.6 (3-100) and 0.8 ± 0.94, respectively (P < .001). One patient (2.2%) and nine survivors (20%) were obese at diagnosis and during the study, respectively (P = .005). Survivors had significantly higher BMI percentile and BMI z-score compared to their siblings (P = .006 and P = .011, respectively). The study group was small and we could not show a correlation of the patients' obesity with RT, thyroid functions, IGF-1, and IGFBP-3 levels. In three survivors (6.8%), there was MS. Maternal and paternal MS was not found as a risk factor for MS of the survivors (P = .1, P = .5, respectively). The HOMA index revealed insulin resistance (IR) in 12 (27.2%) of the survivors, whereas OGTT revealed abnormal glucose regulation and/or IR in four. As a conclusion, ALL survivors have high risk for obesity and MS.

Abstract
The purpose of this study is to compare the efficacy and safety of piperacillin/tazobactam (PIP/TAZO) versus PIP/TAZO plus amikacin in febrile neutropenic children with acute leukemia (AL). Children with AL who had febrile neutropenic episodes were randomized to treatment with PIP/TAZO versus PIP/TAZO plus amikacin. Modification was defined as addition of other antimicrobials and/or antifungal agents to the empirical therapy. Protocol failure was defined as withdrawal of the empirical regimen and introduction of other antimicrobials due to failure in controlling infection. Seventy-two febrile episodes of 42 patients with a median age of 4.5 years (3.5 months to 19 years) were evaluated. There were 37 and 35 episodes in PIP/TAZO and combination arms, respectively. Success without modification, with modification, protocol failure, duration of treatment were 45.9%, 35.1%, 18.9%, and 10 days in PIP/TAZO arm and 42.9%, 37.1%, 20%, and 12 days in combination arm, respectively (P > .05). There was no significant difference between the empirical therapy arms regarding median duration of neutropenia and defervescence of fever. Empirical therapy was substituted by other drugs in 6 and 5 episodes in PIP/TAZO and combination arms, respectively. There was no infection-related death. There was reversible increase in serum creatinine in 1 episode on the combination arm. Monotherapy with PIP/TAZO was effective and safe for initial empirical treatment of febrile neutropenic episodes in children with AL. However, local bacterial resistance patterns should be considered in daily practice. Combination of amikacin with PIP/TAZO did not improve treatment success, but it may increase nephrotoxicity.

Abstract
A 26-month-old male presented with bone marrow failure and dystrophic nail lesions mimicking onychomycosis. There was no skin finding. Treatment with androgen and methylprednisolone was started due to unavailability of a matched-related hematopoietic stem cell donor. After 30 months, transfusion support was required. TINF2 mutation was identified at the age of five and dyskeratosis congenita (DC) was confirmed. TIN2 mutation analysis must be carried out in patients younger than 10 years presenting with bone marrow failure even if characteristic physical anomalies of DC is missing. Genetic confirmation of DC prevents ineffective immunotherapy with misdiagnosis of acquired aplastic anemia.

Abstract
The aim of this study is to describe the health status, health care received, and their impact on the quality of life in patients with hemophilia. Patients with severe factor VIII or IX deficiency without inhibitors or other chronic disease were enrolled. Turkish version of the Hemophilia-Specific Quality of Life Index (Haemo-QoL) questionnaire was administered to the pediatric patients aged 4 to 16 years and Haem-A-QoL to the adult patients. Joints were evaluated according to the World Federation of Hemophilia (WFH) orthopedic joint scores.Thirty-nine children/adolescents and 31 adult patients were enrolled. Mean Haemo-QoL scores were 39.6 +/- 15.0 for the children and mean Haem-A-QoL 47.4 +/- 14.1 for the adult patients, respectively. Internal consistency reliability was generally sufficient. Total Cronbach's alpha coefficient was >.70 (range .77-.96) in all the age groups. Mean total WFH orthopedic joint scores were 1.83 +/- 2.7, 4.9 +/- 4.96, and 6.94 +/- 6.15 in 4-7, 8-12, and 13-16-year-old groups, respectively. They were more impaired in the adult patients (16.23 +/-14.12). These results show that the Turkish version of the Haemo-QoL and Haem-A-QoL are reliable instruments to measure the quality of life in the pediatric and adult patients with severe hemophilia. When compared to the Haemo-QoL scores of an international multicenter West European study of children, quality of life in the Turkish patients were more impaired in the subscales of physical health, feeling, view, school and sport, and treatment as well as more impaired WFH joint scores. The authors recommend primary factor prophylaxis and encouraging the patients to learn home treatment to improve joint scores and quality of life.

Abstract
OBJECTIVE Loss of immunity to previous vaccination and timing of re-vaccination in children receiving chemotherapy remains controversial. The aim of this study was to investigate the immunity to vaccine preventable diseases in children with acute lymphoblastic leukemia (ALL). PROCEDURE Sixty-one patients with ALL and 13 healthy siblings were enrolled. Three study groups included newly diagnosed patients (group 1), patients on maintenance chemotherapy (group 2), and patients that completed chemotherapy (group 3). Blood samples for baseline antibody titers were obtained from all the patients and controls. Patients in group 2 were vaccinated with diphtheria, tetanus, and hemophilus influenzae type b (Hib). Patients in group 3 and controls received the measles vaccine in addition to all the above vaccines. In groups 2 and 3, post-vaccination antibody titers were also obtained. RESULTS Patients and controls had no Hib vaccine during primary vaccination. After chemotherapy median antibody levels against diphtheria, tetanus, measles, and Hib were decreased but tetanus antibodies were still at the protective levels. Proportions of the patients with protective levels were 11.1%, 83.3%, 16.7%, and 16.7% for diphtheria, tetanus, Hib, and measles, respectively. Vaccination achieved protective antibody levels in 81%, 100%, 89.5%, and 70% of the patients for diphtheria, tetanus, Hib, and measles, respectively. Vaccine responses during maintenance were also satisfying. CONCLUSION We recommend re-vaccination after 3 months of cessation of chemotherapy. Administration of Hib vaccine may be beneficial after the first 3 months of maintenance chemotherapy especially in children with no primary vaccination followed by a second booster dose after cessation of therapy to increase immunity.

Abstract
OBJECTIVE Premarital hemoglobinopathy screening is one of the important procedures of hemoglobinopathy control program. This is the first report about the prevalence of hemoglobinopathies in Kocaeli. METHODS Study covered screening from July 2005 to the end of the December 2008. Under the auspices of the Ministry of Health and Regional Health authorities blood samples of the couples were obtained during admission to the wedding office. Complete blood counts and hemoglobin variant analysis were performed with automatic counter and high pressure liquid chromotography technique. A genetic counseling was given to carriers of abnormal hemoglobins. RESULTS A total of 88888 people were screened. The frequency of β -thalassemia trait and sickle cell anemia trait were 0.89% and 0.05% respectively. The frequency of high risk couples was 0.01%. CONCLUSION The prevalence of β -thalassemia trait and sickle cell anemia trait was quite low as a reflection of the frequency of eastern and northern Anatolia and migration to Kocaeli from these geographic regions. Although frequency is low, chronic transfusion requirement, high cost of chelating, organ damage, painful crisis and other crisis, availability of stem cell transplantation for a limited number of patients with compatible sibling donors justify premarital screening studies even in less prevalent regions as Kocaeli.

Abstract
AIM In developing countries, nutritional vitamin B(12) deficiency in infants due to maternal diet without adequate protein of animal origin has some characteristic clinical features. In this study, haematological, neurological and gastrointestinal characteristics of nutritional vitamin B(12) deficiency are presented. METHODS Hospital records of 27 infants diagnosed in a paediatric haematology unit between 2000 and 2008 were evaluated retrospectively. RESULTS The median age at diagnosis was 10.5 months (3-24 months). All the infants were exclusively breast fed and they presented with severe nonspecific manifestations, such as weakness, failure to thrive, refusal to wean, vomiting, developmental delay, irritability and tremor in addition to megaloblastic anaemia. The diagnosis was confirmed by complete blood counts, blood and marrow smears and serum vitamin B(12) and folic acid levels. The median haemoglobin level was 6.4 g/dL (3.1-10.6) and mean corpuscular volume (MCV) was 96.8 fL (73-112.3). Some patients also had thrombocytopaenia and neutropaenia. All the infants showed clinical and haematological improvement with vitamin B(12) administration. Patients with severe anaemia causing heart failure received packed red blood cell transfusions as the initial therapy. CONCLUSION Paediatricians must consider nutritional vitamin B(12) deficiency due to maternal dietary deficiency in the differential diagnosis of some gastrointestinal, haematological, developmental and neurological disorders of infants with poor socioeconomic status. Delay in diagnosis may cause irreversible neurological damage.

Abstract
OBJECTIVE Transfusion transmitted hepatitis has been a severe problem in Turkey in pediatric cancer patients and in chronic congenital anemia. The aim of the present study was to investigate the prevalence of hepatitis B, hepatitis C and human immunodeficiency virus infections in these patients in a University Hospital. METHODS Multi-transfused 66 children (59 acute leukemia, 6 thalassemia major, 1 severe hereditary spherocytosis) diagnosed and followed-up between May, 2000 and December, 2006 were evaluated. Screening of all the patients for HbsAg, anti-HBs, anti-HBc, anti-HCV and anti-HIV was performed at presentation and during the last follow-up. Serologic studies of leukemic patients were also repeated at the end of the chemotherapy. Hepatitis B vaccination was administered to unvaccinated patients with anemia. All blood products were provided by Blood Bank of the Center. RESULTS No patient was found HBsAg, anti-HCV or anti-HIV positive at diagnosis and at the end of the therapy. There was history of hepatitis B vaccination in only 42% of the patients at diagnosis due to administration of this vaccine to newborns since 1998. At the beginning of the study, 45 % (n=27) of the leukemic patients were immune for hepatitis B, but after completion of the intensive chemotherapy seropositivity persisted in only 28.8 % (n=17). CONCLUSION Transmission of these viruses is no longer a real problem even in multitransfused immunosuppressed children in Pediatric Hematology Units as a result of the improvements in screening of voluntary blood donors, administration of disposable material in clinics and vaccination by hepatitis B.

Abstract
In addition to premarital screening programs, education of the general population is important in preventing hemoglobinopathies. The aim of the present study was the education of university students. Short questionnaires were applied before and after a prepared lecture. A 20-minute audiovisual education was provided including the clinical characteristics and inheritance of thalassemia and sickle cell anemia (SCA) as well as the importance of carrier screening. The attendance to 42 lectures was low (n= 1348 = 5%). Seventy-four percent of the students had heard of thalassemia. The percentage of the students who had some accurate knowledge was 25% for thalassemia and 11.7% for SCA. Following the lecture, these numbers increased to 86.2% and 72.1% for thalassemia and SCA, respectively. Only 13.6% of the students were aware of the risk of being carriers, but this increased to 78.6% following the lecture; 92.4% learned that these hemoglobinopathies were inherited and 78.8% learned that consanguineous marriages would increase the risk. Education on hemoglobinopathies must be integrated into the curricula of middle schools and high schools.

Abstract
OBJECTIVES Postpartum depression is an important and under-diagnosed problem. The aims of this study were (1) to compare the prevalence of depressive symptomology in Turkish mothers who were 1-3 months postpartum with the prevalence of depressive symptomology in mothers who had not been pregnant for at least 1 year, (2) to identify risk factors associated with depression in both groups, and (3) to examine the effect of postpartum depression on breastfeeding by the mothers. DESIGN Cross-sectional study SETTING Well-baby clinic PARTICIPANTS 326 women enrolled in January 2001; 163 were 1-3 months postpartum, and 163 had not been pregnant in the previous year. RESULTS The prevalence of depressive symptomology in the postpartum and non-postpartum groups was 17% (28/163) and 24.5% (40/163), respectively; this was not statistically significant (P = 0.102). When we compared mean Beck Depression Inventory (BDI) scores, the difference between the two groups was statistically significant (10.75 +/- 8.06 and 12.63 +/- 8.81, respectively, P = 0.045). Premenstrual tension and a history of depression were risk factors for depressive symptomology in both groups. Three or more births and a history of induced abortion were risk factors for depressive symptomology in the non-postpartum group. In the postpartum group, the effect of depression on breast-feeding was not statistically significant (P = 0.7). The generalisability of the study results to the community is limited. CONCLUSION In this study, the prevalence of depressive symptomology in the postpartum and non-postpartum groups did not show a significant difference, but the prevalence of depressive symptomology was high in both groups. Postpartum depression did not have a negative effect on breast-feeding. Lower BDI scores in the postpartum period may be the result of the protective factors of motherhood which is a respected status for women in populations where the preservations of traditions and customs are valued.

Abstract
Visceral and cutaneous leishmaniasis are endemic in the western and southeastern parts of Turkey. We report a sporadic case of visceral leishmaniasis from Kocaeli, which is not an endemic area. The patient, a 10-month-old male infant, had since birth never been outside the city. He was referred to our hospital with a one-month history of fever. Antibiotics were administered but fever persisted. There were Leishman bodies in the bone marrow aspirate, both in macrophages and in clusters among other cells. Immunofluorescence antibody test (IFAT) detected no antibodies in the mother. Liposomal amphotericin B was administered. Visceral leishmaniasis should be considered in the differential diagnosis of patients with persistant fever, hepatosplenomegaly and cytopenia, even in nonendemic areas.

Abstract
The incidence of mechanical and infectious complications of totally implantable central venous access devices (TIDs) must be related to underlying disease, intensity of the chemotherapy, and frequency of manipulations. Records of the patients hospitalized from January 2002 to May 2005 were evaluated. Patients with TIDs were matched with patients without TIDs having the same malignancy and the same anti-neoplastic chemotherapy. Catheter-related complications were documented and corresponding phases of the chemotherapy in matched pairs were compared with regard to infections. TIDs were inserted in 31 patients with a median age of 4.3 years (22 acute leukemia, 1 NHL, and 8 solid tumors). Total number of catheter days was 5268, with a median catheter life of 174 days (range 9-493 days). Nine catheters (29%) were removed due to mechanical and infectious complications. There was 13 catheter-related infections with a rate of 2.46/1000 catheter days. Total number of mechanical complications was 5 and overall rate of complications was 3.41/1000 catheter days. The rate of febrile episodes was 54 and 41 in the TID and no TID group, respectively (p: .11). Duration of neutropenia was 9.6 and 7.4 days and duration of fever per febrile attack was 5.6 and 4.4 days in the TID and no TID group, respectively (p: .047 and .56). Although most of the patients in this study had hematological malignancy and required frequent manipulation, the results were similar to those in developed countries. TIDs are essential for management of chemotherapy in pediatric malignancies with acceptable complications.

Abstract
A 10-month-old white infant presented with abdominal distention and bilateral scrotal hernia. Imaging studies of the abdomen and thorax showed a huge liver with multiple tumor masses and calcification involving all the segments. There was thrombosis in the inferior vena cava and right atrium. alpha-Fetoprotein was 246,000 IU/mL. HB-94 chemotherapy protocol was started at once due to rapid deterioration of the patient. Surgical biopsy performed after the first IPA (ifosfamide, cisplatin, doxorubicin) course showed hepatoblastoma with macrotrabecular variant. After a second IPA course and 2 courses of carboplatin and etoposide, the boy's clinical condition was excellent with normal alpha-fetoprotein but minimal regression and increased calcification in the tumor mass. Hepatic tumor was unresectable and no surgical intervention was performed. Transplantation could not be performed because of high morbidity and mortality. Despite general agreement that complete surgical resection is the cornerstone of treatment for patients with hepatoblastoma, the patient is in remission with 100% Karnofsky score in the 43 months of diagnosis.

Abstract
A cross-sectional method was used to study a group of 400 high school students in Kocaeli, Turkey, aged 14 to 16 years, identified among 17,812 high school students. Students from 10 high schools were selected using a random sampling method. Whole blood counts were performed as a screening test for anemia. Serum ferritin levels and, when necessary, hemoglobin electrophoresis were determined for anemic students. Iron medication was prescribed for iron deficiency and genetic counseling was given to adolescents with thalassemia trait. Out of 338 participating students (mean age, 14.72+/-0.71 y), anemia (hemoglobin <12 g/dL for girls and <13 g/dL for boys) was detected in 17/174 girls (9.7%) and 6/164 boys (3.6%). Iron deficiency anemia was detected in 20/23 (86.9%) of anemic children [15/17 (88.2%) girls and 4/6 (66.6%) boys]. Of 23 students with anemia 2 had beta-thalassemia trait and 2 had both iron deficiency, and beta-thalassemia trait. Etiology of anemia could not be defined in 1 student. The prevalence of adolescent anemia in Kocaeli is almost equal to that in developed countries.

Abstract
The purpose of this study was to compare the efficacy, safety, and cost of piperacillin/tazobactam with cefepime monotherapy in children with febrile neutropenia. A prospective randomized study in children and adolescent with cancer was conducted. Patients were randomly assigned to receive either 80 mg/kg piperacillin/10 mg/kg tazobactam every 6 h (maximum 4.5 g/dose) or cefepime 50 mg/kg every 8 h (maximum 2 g/dose). Treatment modification was defined as all the changes in the empirical antimicrobials after the first 96 h. Overall treatment success was defined as cure of febrile episode with or without modification. Cost of hospitalization, antimicrobial drugs, and supportive therapy were calculated. Fifty febrile neutropenic episodes (25 in the piperacillin/tazobactam group, 25 in the cefepime group) in 27 pediatric cancer patients were evaluated. The groups were comparable in terms of age, gender, body weight, primary diagnosis, disease status, initial neutrophil count, and duration of neutropenia. Microbiologically and clinically documented infection rate was 46%. There was no infection-related mortality in the study period. The treatment success of initial empirical therapy without modification was not different in the 2 groups (56% in piperacillin/tazobactam group and 48% in cefepime group). Anti-anaerobic drugs were added more frequently in the cefepime group. Duration of fever, neutropenia, treatment, and cost of therapy were not different in the treatment groups. Piperacillin/tazobactam monotherapy is as effective as cefepime monotherapy in febrile neutropenia of pediatric cancer patients.

Abstract
Differential diagnosis between tuberculous peritonitis and peritonitis carcinomatosis is extremely difficult in patients with ascites, peritoneal implants and elevated CA 125 level. A 16-year-old girl presented with abdominal distention, intermittent fever and weight loss. Physical examination and radiologic studies revealed massive ascites, generalized peritoneal thickening and slightly enlarged right ovary with a cystic mass and left pleural effusion. Serum CA 125 was 939 U/L (normal range: 0-35 U/L) and other tumor markers including alpha fetoprotein (AFP) and beta-human chorionic gonadotropin (HCG) were within normal range. Acid-fast stain and culture were negative for Mycobacterium tuberculosis. Diagnostic laparoscopy and biopsy were performed with the presumptive diagnosis of peritonitis carcinomatosis, and histologic examination revealed multiple granulomas with epithelioid cells and caseification necrosis which confirmed tuberculosis. Quadruple anti-tuberculosis treatment was administered and the patient's clinical findings and serum CA 125 level returned to normal. In conclusion, tuberculous peritonitis should be considered in the differential diagnosis of patients with ascites and elevated serum CA 125. This marker may be useful in monitoring treatment response.

Abstract
The study aimed to compare diastolic and systolic dysfunctions detected by echocardiography (ECHO) and multigated radionuclide angiography (MUGA) in patients with cancer in the first 3 months after anthracycline-comprising chemotherapy. Children with leukemia and solid tumors who had anthracycline-comprising chemotherapy were enrolled in the study. ECHO and MUGA were performed in all patients before the first chemotherapy course and in the first 3 month of completing anthracycline-comprising chemotherapy. Cumulative anthracycline doses per body surface were calculated. Left ventricular systolic and diastolic functions were measured by both techniques. Twenty-one patients with a median age of 6.9 +/- 3.6 years were enrolled in the study. Mean cumulative anthracycline doses were equivalent to 276 +/- 83 mg/m2 doxorubicin. After anthracycline chemotherapy, cardiac dysfunction was detected in 14 and 48% of the patients by ECHO and MUGA, respectively. All dysfunctions detected by ECHO were systolic, whereas 29% of the patients had diastolic and 38% of the patients had systolic dysfunction in MUGA study. Although the study group is small, MUGA seems more sensitive in detecting anthracycline-induced systolic and diastolic cardiac dysfunctions compared to ECHO.

Abstract
Premature infants<1500 g were randomly assigned to study and control groups. In the study group, 42 premature infants received recombinant human erythropoietin (r-Hu EPO) 750 U/kg per week subcutaneously from day 5 to 40 and enteral iron supplementation of 2 to 6 mg/kg/d beginning on day 14 provided that they were receiving at least 50% energy intake orally. In the control group, 51 infants received the same dose of enteral iron supplementation beginning at the end of the fourth week. At the end of a 12-week monitoring period, r-Hu EPO combined with early enteral iron reduced transfusion needs only in the subgroup<1000 g. r-Hu EPO and early iron treatment had no effect on the development of severe retinopathy of prematurity, intraventricular hemorrhage, necrotizing enterocolitis, and bronchopulmonary dysplasia. We suggest that r-Hu EPO combined with early enteral iron is both effective and safe in infants<1000 g.

Abstract
Bloody nipple discharge occurs rarely in infancy and may be secondary to mammary ductal ectasia. Discharge commonly resolves spontaneously, and ultrasonography is a useful diagnostic technique to detect the cause of discharge. We report a 28-month-old boy who presented with unilateral bloody nipple discharge for one month without signs of infection or mass. Ultrasound examination showed a dilated duct in the retroareolar region. No atypical cells were present on cytologic evaluation of the discharge. Further diagnostic studies were avoided and the discharge ceased completely one month later. We conclude that bloody nipple discharge is usually a benign and self-limited process in infancy and that it is advisable to avoid unnecessary invasive investigations initially. Invasive diagnostic studies or surgery should be reserved for cases with a palpable mass, persistent discharge or equivocal ultrasonographic findings.
