The antivascular endothelial growth factor antibody, bevacizumab, is effective against several malignancies in adults but unproven in pediatric oncology. In early phase pediatric studies toxicities were similar to those in adults. Bowel perforation in adults is a rare but serious toxicity, but has not been hitherto reported in children. A 5-year-old boy with chemoresistant neuroblastoma treated with bevacizumab plus radioimmunotherapy developed acute abdominal pain. Computed tomography scan showed free abdominal air and pneumatosis coli...

Sickle cell orbitopathy is a rare manifestation of a sickle cell crisis and can closely mimic orbital cellulitis, both clinically and radiologically. We present a case where a child presented with what was thought to be orbital cellulitis and was treated accordingly. Subtle radiologic features of sickle cell orbitopathy were initially overlooked, resulting in an incorrect diagnosis and a treatment delay for the patient. Correctly treated most cases resolve with no adverse affects, highlighting how important it is to consider acute sickle cell orbitopathy in the differential diagnosis of acute periorbital swelling in children with sickle disease...

The use of extracorporeal life support (ECLS) as ultimate salvage therapy for hematopoietic stem cell transplant recipients remains controversial among oncologists and critical care specialists. Prognosis is poor, particularly after allogeneic transplantation, and literature to guide clinical decision-making is scarce. Our report describes successful ECLS in a pediatric patient undergoing allogeneic hematopoietic stem cell transplantation, who developed acute respiratory failure during severe neutropenia, followed by immediate neutrophil engraftment...

In this report we describe a patient with neonatal cholestasis who was found to have a liver lesion with suspicious imaging features, although ultimately it was histologically proved to be a pseudotumor. We discuss the characteristic features and imaging findings of macroregenerative nodules of the liver.

We report the clinical history of 2 female patients with Ewing sarcoma and microscopic ovarian infiltration. In both cases, the initial workup found no metastasis. However, the examination of cryopreserved ovarian tissues revealed the presence of CD99 positive tumor cells with rearrangement of EWS gene confirmed by FISH. Both children were treated as patients with localized tumor and are currently in remission. These reports underline that, in Ewing sarcoma patients, retransplantation of cryopreserved ovarian tissue is not harmless and could lead to cancer relapse...

Leukemic relapse in the central nervous system (CNS) after conventional treatment is associated with a poor prognosis. The effectiveness and safety of IV infusion of human leukocyte antigen (HLA)-mismatched lymphocytes for leukemia, and intrathecal (IT) infusion of HLA-mismatched lymphocytes for cerebrospinal fluid (CSF) dissemination of medulloblastoma have been reported. A 13-year-old girl (HLA-A31) was diagnosed as relapsing from Philadelphia chromosome-positive acute leukemia in the CNS after receiving chemotherapy, tyrosine kinase inhibitors, haploidentical hematopoietic stem cell transplantation (HSCT) from her father (HLA-A31), and craniospinal irradiation...

BACKGROUND: Antifungal prophylaxis (AFP) is recommended in at-risk hematology-oncology patients. We evaluated the safety of AFP with voriconazole (VRC) in pediatric hematology/oncology patients. MATERIALS AND METHODS: A retrospective study of VRC AFP in children with malignancies hospitalized in all 7 Greek pediatric hematology/oncology centers during 2008 to 2012 was conducted. Patients' demographics, outcome, and adverse event (AE) data were recorded. RESULTS: Four hundred twenty-nine VRC AFP courses in 249 patients (median age 6 y, 55% boys) were studied...

Hemophagocytic lymphohistiocytosis is characterized by uncontrolled activation of the immune system that leads to systemic hyperinflammation. Lymphoproliferative syndrome linked to the X chromosome is a hereditary immunodeficiency characterized by an inability to mount an adequate immune response to an Epstein-Barr virus infection. Hemophagocytic lymphohistiocytosis is one of the main clinical features of X-linked lymphoproliferative syndrome. We report the case of a patient who presented with primary hemophagocytic lymphohistiocytosis associated with Epstein-Barr virus infection without a familial history of immunodeficiency...

A 14-month-old Nepalese infant had developed a rapidly growing facial tumor originating from a dark spot on her upper eyelid. A cavernous hemangioma was suspected and treated with high doses of propranolol and prednisolone. Remission was dramatic. Histology confirmed alveolar rhabdomyosarcoma. Chemotherapy was planned but not carried out due to complicated logistics. The girl died at the age of 3. We present this case for discussion as to whether propranolol and prednisolone might be effective in rapidly growing rhabdomyosarcomas...

Ewing sarcoma is a pediatric bone and soft tissue sarcoma that requires intensive therapy, which can cause secondary malignancies. We present a rare case of early, treatment-related AML in a pediatric patient concurrently receiving primary therapy for Ewing sarcoma. Despite AML-directed therapy, our patient died secondary to complications of hyperleukocytosis. Cytogenetic and mutation profiling of the leukemia cells revealed the DNA-topoisomerase-II-inhibitor-associated t(9;11)(p22;q23) translocation and clonal KRAS and BRAF mutations...

Neuroblastoma accounts for 15% of all pediatric cancer deaths. Intersectin 1 (ITSN1), a scaffold protein involved in phosphoinositide 3-kinase (PI3K) signaling, regulates neuroblastoma cells independent of MYCN status. We hypothesize that by silencing ITSN1 in neuroblastoma cells, tumor growth will be decreased in an orthotopic mouse tumor model. SK-N-AS neuroblastoma cells transfected with empty vector (pSR), vectors expressing scrambled shRNA (pSCR), or shRNAs targeting ITSN1 (sh#1 and sh#2) were used to create orthotopic neuroblastoma tumors in mice...

Osteosarcoma is the most common primary malignant tumor of the bone. The most common sites of osteosarcoma in children are the metaphysis of long bones, especially the distal femur, proximal tibia, and proximal humerus. It occurs very rarely in flat bones. Here we report a 14-year-old adolescent boy with primary osteosarcoma of the fifth rib and a review of literature.

BACKGROUND: As previous studies had discordant results with regard to the correlation of transcranial Doppler (TCD) screening and brain MRI, the aim of this study was to find the correlation between TCD values and silent ischemia in sickle cell disease (SCD) patients. METHOD AND MATERIALS: In this cross-sectional study, 50 patients with proven diagnosis of sickle cell hemoglobinopathies based on their hemoglobin electrophoresis were included. Demographic data, their physical exam, information with regard to crises history, and their laboratory data were recorded...

Lupus anticoagulant, also known as lupus antibody, is generally associated with thrombosis rather than bleeding events. Lupus anticoagulant-hypoprothrombinemia syndrome in children is rather rare but can lead to mild to life-threatening bleeding. Here, we report 3 cases of lupus anticoagulant-hypoprothrombinemia syndrome associated with systemic lupus erythematosus. They initially presented with mucocutaneous bleedings, and subsequently developed other symptoms fulfilling the laboratory criteria for systemic lupus erythematosus...

Immune reconstitution inflammatory syndrome (IRIS) is a clinical condition emerging after immune recovery of an immunocompromised status, mostly in human immunodeficiency virus infected patients but also in several other settings, such as the recovery from the severe combined immunodeficiency status after hematopoietic stem cell transplantation. Herein, we report a patient transplanted for severe combined immunodeficiency who developed IRIS for 2 times, namely shortly after transplantation and after donor lymphocyte infusion...

Congenital thrombotic thrombocytopenia purpura (cTTP) is a very rare disorder worldwide. Standard treatment of recognized cases has been to administer fresh frozen plasma as the source of ADAMTS13, to replenish the absent ADAMTS13 enzyme. An alternative source, a plasma-derived factor VIII concentrate used for hemophilia A, and found to contain this enzyme, was reported to be effective in 1 patient in the United States. We now report details on a US cohort of 8 cTTP patients who have been successfully treated for varying periods with a marketed antihemophilic factor concentrate Koate-DVI...

Sickle retinopathy reflects disease-related vascular injury of the eye, which can potentially result in visual loss from vitreous hemorrhage or retinal detachment. Here we review sickle retinopathy among children with sickle cell disease, describe the epidemiology, pediatric risk factors, pathophysiology, ocular findings, and treatment. Newer, more sensitive ophthalmological imaging modalities are available for retinal imaging, including ultra-widefield fluorescein angiography, spectral-domain optical coherence tomography, and optical coherence tomography angiography...

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...
