Hepatic non-Hodgkin lymphoma and hepatoblastoma complicating ataxia-telangiectasia.
Immunopharmacol Immunotoxicol
PUBLISHED: 04-04-2011
Show Abstract
Hide Abstract
Patients with ataxia-telangiectasia (A-T) have an increased risk of developing malignancies and are prone to severe early or late toxicity owing to chemotherapy. Leukemia and lymphoma account for about 85% of malignancies, but solid tumors have also been reported. We describe an unusual case of an 8-year-old child affected by A-T, who presented a primary hepatic B-cell non-Hodgkin lymphoma, treated with reduced doses of R-CHOP cycles plus rituximab. Three years later, the patient developed hepatoblastoma as a second malignancy. This case clearly emphasizes the need for intensive monitoring of A-T patients for early signs of malignancy and the opportunity to consider specific and modified regimens of chemotherapy.

Hepatic veno-occlusive disease during chemotherapy for nephroblastoma: successful and safe treatment with defibrotide. Report of a clinical case.

Hide Abstract
Here we report a case of administration of defibrotide in an 11 months old infant with hepatic veno-occlusive disease during chemotherapy for nephroblastoma. He presented with abdominal distension, a weight gain of 15%, ascites, hepatomegaly with right upper quadrant pain, thrombocytopenia and hypertransaminasemia. Despite therapy, his clinical conditions aggravated, and, therefore intravenous administration of defibrotide on a compassionate-use basis was started. The dosage was 15 mg/kg/day in 4 divided doses, which was increased gradually (in 3 days) to 40 mg/kg/day in 4 divided doses. Defibrotide proved safe and effective in resolving clinical symptoms and normalizing serological findings in the syndrome.

Successful treatment with Protein C of febrile neutropenia in pediatric patients during cancer therapy.
Immunopharmacol Immunotoxicol
PUBLISHED: 02-25-2009
Show Abstract
Hide Abstract
Febrile Neutropenia (FN) is a complication of chemotherapy in childhood cancer and at the same time secondary deficit of Protein C (PC) is often present during sepsis in children with cancer. In this study we have compared the clinical outcome of two different groups. At the onset of FN during chemotherapy the first group (patients with a secondary deficit of PC) received Protein C Concentrate (PCC) replacement while the other group without PC deficiency received only symptomatic therapies. We report that PC replacement could shorten duration of FN and improve the clinical outcome. The administration of PCC was safe and without any complications.

Necrotizing fasciitis of the lower limbs.
Pediatr Rep
Show Abstract
Hide Abstract
We report an uncommon severe soft-tissue infection of the thighs in a male child with acute lymphoblastic leukemia. Early and aggressive medical treatment and the conservative surgical approach were successful. Necrotizing fasciitis should be suspected in any soft-tissue infection until it can be definitely ruled out, since prompt deliver of medical and surgical intervention is essential.

Bone marrow-infiltrating human neuroblastoma cells express high levels of calprotectin and HLA-G proteins.

Show Abstract
Hide Abstract
Metastases in the bone marrow (BM) are grim prognostic factors in patients with neuroblastoma (NB). In spite of extensive analysis of primary tumor cells from high- and low-risk NB patients, a characterization of freshly isolated BM-infiltrating metastatic NB cells is still lacking. Our aim was to identify proteins specifically expressed by metastatic NB cells, that may be relevant for prognostic and therapeutic purposes. Sixty-six Italian children over 18 months of age, diagnosed with stage 4 NB, were included in the study. Metastatic NB cells were freshly isolated from patients BM by positive immunomagnetic bead manipulation using anti-GD2 monoclonal antibody. Gene expression profiles were compared with those obtained from archived NB primary tumors from patients with 5 y-follow-up. After validation by RT-qPCR, expression/secretion of the proteins encoded by the up-regulated genes in the BM-infiltrating NB cells was evaluated by flow cytometry and ELISA. Compared to primary tumor cells, BM-infiltrating NB cells down-modulated the expression of CX3CL1, AGT, ATP1A2 mRNAs, whereas they up-regulated several genes commonly expressed by various lineages of BM resident cells. BM-infiltrating NB cells expressed indeed the proteins encoded by the top-ranked genes, S100A8 and A9 (calprotectin), CD177 and CD3, and secreted the CXCL7 chemokine. BM-infiltrating NB cells also expressed CD271 and HLA-G. We have identified proteins specifically expressed by BM-infiltrating NB cells. Among them, calprotectin, a potent inflammatory protein, and HLA-G, endowed with tolerogenic properties facilitating tumor escape from host immune response, may represent novel biomarkers and/or targets for therapeutic intervention in high-risk NB patients.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
