Pneumothorax is a well-described complication of osteosarcoma. Conversely, the presence of a pneumomediastinum to our knowledge has been reported just once in a patient with osteosarcoma, and never without detectable lung metastasis. We report the case of an 18-year-old male with a localized, distal femur osteosarcoma who was found to have an asymptomatic pneumomediastinum and pneumatocele at diagnosis, and then 16 months later experienced a pulmonary relapse. Our case suggests that these findings may represent the presence of occult metastatic disease and cautions providers to treat appropriately and provide surveillance with a high index of suspicion for pulmonary recurrence...

The aim of the present study was to evaluate in patients with acute lymphoblastic leukemia (ALL), the oxidative status and antioxidant defense and its involvement in the relapse of ALL. The plasmatic levels of malondialdehyde, advanced oxidation of protein products and reduced glutathione (GSH), and the plasmatic activities of catalase, superoxide dismutase (SOD), and glutathione peroxidase were determined in 34 patients who were newly diagnosed with ALL and compared with 92 healthy individuals. The plasmatic concentrations of malondialdehyde and advanced oxidation of protein products were higher in ALL patients than in controls and increased during chemotherapy...

BACKGROUND: Autoimmune cytopenias are characterized by immune-mediated destruction of hematopoietic cell lines with immune thrombocytopenia (ITP) affecting platelets and Evans syndrome (ES) affecting platelets and red blood cells. For patients with persistent disease, limited options for effective and well-tolerated therapies exist. OBJECTIVES: Our aim is to describe our institution's experience with sirolimus as therapy for pediatric patients with persistent ITP and ES...

Metastatic osteosarcoma with direct cardiac involvement is an exceptionally rare finding, with only 63 total reported cases in the English literature over the past 123 years. Although the precise incidence is unknown, we estimate that direct cardiac involvement currently occurs in <2% of metastatic osteosarcoma cases. We also find that before the adoption of adjuvant chemotherapy as a standard of care therapy for osteosarcoma, metastatic osteosarcoma to the heart was much more common than it is today, as cardiac involvement occurred in ∼20% of cases of metastatic osteosarcoma before the 1980s...

Acute complications requiring admission to pediatric intensive care unit (PICU) are frequent for children with cancer. Our objective was to determine early prognostic factors of mortality in a cohort of children with cancer hospitalized in PICU for acute complications and particularly to assess whether the delay before admission to a PICU is an early predictor of mortality. We conduct a retrospective multicenter analysis. All patients transferred in PICU for acute complications between January 2002 and December 2012 were included...

Hemolytic anemia is a well-recognized complication in patients with left-sided mechanical heart valves. It is rare to see hemolysis with a bioprosthetic valve in the right ventricular outflow tract. We report a 4-year-old-girl with history of truncus arteriosus status-post repair who developed hemolytic anemia as a result of a calcified and obstructed bioprosthetic right ventricular to pulmonary artery-valved conduit. The hemolysis was alleviated by replacing the obstructed conduit with a larger valved conduit...

Liver fibrosis is one of the common complications of transient myeloproliferative disorder (TMD) in Down syndrome (DS), but the exact molecular pathogenesis is largely unknown. We herein report a neonate of DS with liver fibrosis associated with TMD, in which we performed the serial profibrogenic cytokines analyses. We found the active monocyte chemoattractant protein-1 expression in the affected liver tissue and also found that both serum and urinary monocyte chemoattractant protein-1 concentrations are noninvasive biomarkers of liver fibrosis...

This study report clinical course, etiology, management, and long-term outcome of children who developed toxic epidermal necrolysis-like reaction (TEN-LR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We retrospectively collected children with TEN-LR occurring after allo-HSCT performed in 2 pediatric bone marrow units between 2005 and 2014. We identified 6 cases of TEN-LR of 322 patients (1.8%). Possible triggers of TEN included antibiotics, antiepileptics, antimycotics, and Mycoplasma infection...

Although it is well-established that children undergoing allogeneic stem cell transplants and treatment for leukemia should be offered prophylaxis against Pneumocystis jirovecii pneumonia, the risk for children with solid malignancies is less certain. This guideline has been developed with the aim of standardizing practice and optimizing the benefit versus risk of prophylactic medication in this group of patients. P. jirovecii pneumonia has a high mortality rate even with prompt antimicrobial treatment. Since prophylaxis with co-trimoxazole is safe, effective, and inexpensive, we suggest that all children with malignancies undergoing immunosuppressive therapy are offered prophylaxis unless there are clear contraindications...

The aim of this study was to determine usefulness of measurements of maximal systolic velocity of the hepatic artery with Doppler ultrasonography in the diagnosis of venoocclusive disease (VOD) after hematopoietic stem cell transplantation. We prospectively obtained 5 sonograms per patient: pretransplantation, day +1, +7, +14, and +28 on 36 nonconsecutive children who underwent hematopoietic stem cell transplantation. We examined the hepatic artery, the portal, hepatic and splenic veins, the thickness of the gallbladder wall, the presence of ascites, and the liver and spleen size...

Accumulating evidence indicates that polymorphisms in folate pathway genes play a role in response to methotrexate (MTX) treatment in various diseases. This study explored the influence of these genetic polymorphisms on treatment outcome in pediatric osteosarcoma. Blood and tissue samples from 48 osteosarcoma patients were obtained, and the following polymorphisms were analyzed; SLC19A1 80G>A, DHFR 829C>T, MTHFR 677C>T, MTHFR 1298A>C, and ATIC 347C>G. We evaluated associations between these candidate gene polymorphisms and treatment outcome, including histologic response and event-free and overall survival, of patients treated with high-dose MTX...

Treatment for medulloblastoma carries significant risks, particularly in resource-constrained settings. We report a case of a Mexican infant with desmoplastic/nodular medulloblastoma. Given the nature of her tumor, we developed a tailored regimen following subtotal resection to avoid both radiation therapy and the high-dose cisplatin therapy offered at most centers in the United States. The patient is in remission 4 years after the initial diagnosis. This case suggests an alternative treatment plan for this particular tumor variant that accommodates the limited resources of many centers around the world and avoids the risks associated with radiation therapy at a young age...

BACKGROUND: Palifermin has been proven to decrease the frequency of severe oral mucositis in adult patients with sarcoma and metastatic colorectal cancer receiving chemotherapy. The impact of palifermin on the incidence of mucositis in nonhematopoietic stem cell transplantation (HSCT) pediatric population receiving chemotherapy has never been reported to date. PATIENTS AND METHODS: This is a retrospective analysis of pediatric patients who received palifermin as secondary prophylaxis to prevent chemotherapy-induced mucositis at Memorial Sloan Kettering Cancer Center from January 1, 2008 to 2014...
