With improvements in molecular diagnostic methods, report of Human bocavirus (HBoV) as an etiologic agent in many studies on viral respiratory and gastrointestinal infections has been increasing. Two pediatric patients who presented with secondary hemophagocytic lymphohistiocytosis were examined for etiologic causes, including viruses. Whole bacterial and fungal cultures and viral serological studies were negative. Viral polymerase chain reaction of nasopharyngeal secretions showed HBoV. One was successfully treated with intravenous immunoglobulins, whereas the other died with multiorgan failure...

Sideroblastic anemias are a rare group of disorders resulting from defective iron incorporation during heme synthesis and hence characterized by anemia and presence of ringed sideroblasts in bone marrow. The most common form is an X-linked disorder caused by mutations in ALAS2 gene. In the current paper, a case of X-linked sideroblastic anemia caused by a novel homozygous deletional mutation in exon 10 of ALAS2 gene is presented. The female infant developed moderately severe anemia at 6 months of age, which did not improve despite adequate nutritional support...

Atypical teratoid/rhabdoid tumor (AT/RT) is a malignant tumor that is commonly associated with biallelic alterations of SMARCB1. Recurrent or refractory AT/RT has not been molecularly characterized as well. We present the case of a child with recurrent AT/RT who underwent clinically integrated molecular profiling (germline DNA and tumor DNA/RNA sequencing). This demonstrated a somatic lesion in CDKN1C alongside hallmark loss of SMARCB1. This data allowed us to explore potential personalized therapies for this patient and expose a molecular driver that may be involved in similar cases...

FK506 (tacrolimus) is an immunosuppressive drug and more potent than cyclosporine. FK506 is widely used for immunosuppression in the prevention and treatment of graft-versus-host disease after allogeneic bone marrow transplantation and solid organ transplantation. Neurotoxicity is a recognized complication of FK506 therapy, but ptosis and weakness of eye abduction unilaterally has not been reported in association with FK506 administration to date. We discuss a 13-year-old male patient who developed ptosis and weakness of eye abduction unilaterally 90 days after transplantation with bone marrow from an unrelated donor, for acute lymphoblastic leukemia in this case report...

Atypical rhabdoid/teratoid tumor (ATRT) is an uncommon and highly malignant tumor of the central nervous system. The majority of ATRT tumors occur in infancy and young children located in the posterior fossa. The ideal treatment for cure remains controversial and prognosis is typically unfavorable. We present a case of an atypical presentation of ATRT, presenting in adolescence with an additional low-grade glioneuronal tumor discovered at diagnosis.

Height at diagnosis has been analyzed in connection with acute lymphoblastic leukemia (ALL). Most prior studies have compared cases to national reference data derived from previous birth cohorts. Our objective was to determine the association of height-for-age Z score (HAZ) at time of diagnosis with the odds ratio (OR) of ALL in a case-control study (N=498) with a contemporaneous population of age-matched, sex-matched, and ethnicity-matched controls. We hypothesized that cases would have greater mean HAZ at time of diagnosis/interview, after adjustment for weight-for-age (WAZ) and weight-for-height (WHZ)...

In the literature, studies on the oxidant effects of nontransferrin bound iron [NTBI (eLPI assay)] during chemotherapy of acute lymphoblastic leukemia and acute myeloblastic leukemia are lacking. We established NTBI and oxidative stress determinants (OSD), iron parameters, high-sensitive C-reactive protein (hs-CRP) levels, liver tests, cumulative chemotherapeutic doses, and transfused blood in 36 children with acute leukemia throughout chemotherapy. These parameters were determined at the beginning and end of chemotherapy blocks (11 time points) and in 20 healthy children using enzyme-linked immunosorbent assay, and colorimetric and fluorometric enzymatic methods...

Invasive fungal infections are rare in children with acute lymphoblastic leukemia. It compromises the antileukemia therapy should it happen. Central nervous system fungal infections carry high mortality. We here report the case of a 6.5-year-old girl who developed multiple central nervous system fungal abscesses possibly due to Aspergillus infection during induction therapy for acute lymphoblastic leukemia who has been successfully managed without compromising antileukemia therapy. She has been receiving antifungal therapy and maintenance chemotherapy for 20 months from diagnosis...

We have aimed to determine the effect of polymorphisms in regulatory regions of the DHFR gene in relation to methotrexate (MTX) dose adjustments and drug-induced toxicity in children on maintenance therapy for acute lymphoblastic leukemia (ALL). In total, 41 children diagnosed with ALL were screened for 3 tag-single nucleotide polymorphisms in the DHFR promoter (C-1610G, C-680G/T, A-317G) and an intronic 19-bp insertion/deletion. Genotypes were analyzed in relation to dose requirements and toxicity. The percentage of MTX dose administered (with respect to protocol-recommended values) was affected by DHFR polymorphisms...

Inherited thrombocytopenia is a topic that was expanded greatly over the last decade and many new genes are being identified. However, inheritance patterns are not always easy to identify because sporadic cases from de novo mutations may in fact be more common. Few studies have assessed the relationship between thrombocytopenia and malignancies, specifically acute lymphoblastic leukemia (ALL). Here we present a pediatric case of persistent thrombocytopenia associated with T-cell ALL. Our patient was initially diagnosed with immune thrombocytopenic purpura with no evidence of malignancy on bone marrow biopsy but presented shortly after with ALL...

Plasma cell myeloma (PCM) is rare in children and young adults and therefore may be difficult to diagnose. Here we report the clinicopathologic findings of 4 patients under the age of 30 diagnosed with PCM at our institution and summarize the literature about 48 other cases of PCM in this age group. The male:female ratio was 1.2:1 and the number of cases increased with age. Children and young adults with PCM often present with a plasmacytoma and are less likely to have asymptomatic PCM than their adult counterparts...

The increased awareness about the severity of complications in thalassemia intermedia patients led authorities to develop strategies for better management and follow-up of these patients. In this study, we aimed to define the clinical and laboratory characteristics in previously followed-up β-thalassemia intermedia patients and wanted to gain an insight about the follow-up of this patient population in a developing country to provide them better care in the future. The mean age at diagnosis was 4 years, and the mean hemoglobin was 7...

Children with hemophagocytic lymphohistiocytosis (HLH) are at an increased risk of critical illness. In this study, we described the clinical characteristics of critically ill children with HLH and identify factors associated with poor clinical outcomes. Children who were diagnosed with HLH with emergent admission to Children's Intensive Care Unit (CICU) between January 1, 2000 and October 31, 2015 were included. The primary outcome was CICU mortality. Over the 15-year period, there were 14 critically ill patients with HLH with 23 CICU admissions...

Systemic Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disease of childhood is a rare disease and has a very fulminant clinical course with high mortality. A 21-month-old female patient was referred to our hospital with a 1 week history of fever and was subsequently diagnosed with systemic Epstein-Barr virus-positive T-cell lymphoproliferative disease of childhood. After starting treatment with dexamethasone, she showed early defervescence and improvement of laboratory parameters, and has remained disease-free after stopping steroid treatment, although longer follow-up is necessary...

BACKGROUND: Pretreatment neutrophil-to-lymphocyte ratio (NLR) and absolute lymphocyte count (ALC) recovery have been shown to be associated with prognosis in several types of cancer in adults. However, evidence in pediatric cancer is scarce. The aim of our study was to evaluate whether pretreatment NLR and lymphocyte recovery are prognostic factors in pediatric sarcomas. MATERIALS AND METHODS: Study participants were identified from a retrospective cohort of 100 children with osteosarcoma (n=55), rhabdomyosarcoma (n=22), and Ewing sarcoma (n=23)...

Congenital amegakaryocytic thrombocytopenia is a rare disorder causing thrombocytopenia that progresses to pancytopenia and bone marrow failure if untreated. It is caused by variants in the MPL gene which encodes the thrombopoeitin receptor. In this report, we review 5 cases of congenital amegakaryocytic thrombocytopenia, all of whom belong to the Mississippi Band of Choctaw Indians. There are 2 common variants in these cases: R90X and R537W. One variant was previously reported only once and had unclear significance at that time...

Lung cavitary lesions are a rare finding in the nontransplant setting of a patient with acute leukemia. Among viral agents, cytomegalovirus (CMV) may cause pulmonary nodules and cavities in patients undergoing hematopoietic stem cell transplantation, but during pediatric acute lymphoblastic leukemia treatment, CMV disease is less common. Here we report the case of a boy affected by acute lymphoblastic leukemia who suffered severe cavitary CMV pneumonia during chemotherapy, and we review the current literature...

Vincristine is a widely used chemotherapeutic agent in the treatment of childhood malignancies. Neuropathy is the most common adverse effect. CYP3A4 and CYP3A5 enzymes of cytochrome p450 enzyme system are responsible in vincristine metabolism. Genetic polymorphism may alter the vincristine metabolism and the neurotoxicity rate. In this study, distribution of CYP3A5 alleles among Turkish children with malignancies, relation between CYP3A5 genotype and neurotoxicity rates, as well as severity and duration of neuropathy and total vincristine doses were investigated...
