Diffuse Hemorrhagic Colitis in a Patient With Dyskeratosis Congenita After Nonmyeloablative Allogeneic Hematopoietic Stem Cell Transplantation.
J. Pediatr. Hematol. Oncol.
PUBLISHED: 07-08-2014
Show Abstract
Hide Abstract
Dyskeratosis congenita (DC) is a rare inherited disorder characterized by reticular skin pigmentation, oral cavity leukoplakia, and nail dystrophy. Bone marrow failure in DC can only be cured by allogeneic hematopoietic stem cell transplantation (HSCT). After a nonmyeloablative, matched unrelated donor transplant, the 21-year-old patient experienced severe lower gastrointestinal tract hemorrhage caused by diffuse colitis. The etiology remained unclear. Diffuse colitis with life-threatening hemorrhage has now been reported in 3 DC patients after unrelated allogeneic HSCT. To identify the underlying causes and the disease-specific risks, and to allow for prevention and/or optimal management, data should be prospectively collected.

Breast cancer in young women after treatment for Hodgkin's disease during childhood or adolescence--an observational study with up to 33-year follow-up.

Hide Abstract
The treatment of Hodgkin's disease (HD; also called Hodgkin's lymphoma) in children and adolescents with radiotherapy and chemotherapy leads to high survival rates but has a number of late effects. The most serious one is the development of a secondary malignant tumor, usually in the field that was irradiated. In women, breast cancer can arise in this way.

Leukemic hypopyon uveitis in acute myeloid leukemia (AML) is a very rare condition. We report this case of an unusual finding in a 2½-year-old boy in second remission after chemotherapy for relapsed AML.

Fast selection of maribavir resistant cytomegalovirus in a bone marrow transplant recipient.
BMC Infect. Dis.
PUBLISHED: 02-06-2013
Show Abstract
Hide Abstract
Human cytomegalovirus infections are still significant causes of morbidity and mortality in transplant recipients. The use of antiviral agents is limited by toxicity and evolving resistance in immunocompromised patients with ongoing viral replication during therapy. Here, we present the first documented case of genotypic resistance against maribavir in a bone marrow transplant (BMT) recipient.

Risk of complications during hematopoietic stem cell collection in pediatric sibling donors: a prospective European Group for Blood and Marrow Transplantation Pediatric Diseases Working Party study.
Blood
PUBLISHED: 12-12-2011
Show Abstract
Hide Abstract
We investigated prospectively factors influencing the safety of hematopoietic stem cell (HSC) collection in 453 pediatric donors. The children in the study donated either BM or peripheral blood stem cells (PBSCs) according to center policy. A large variability in approach to donor issues was observed between the participating centers. Significant differences were observed between BM and PBSC donors regarding pain, blood allotransfusion, duration of hospital stay, and iron supplementation; however, differences between the groups undergoing BM vs PBSC donation preclude direct risk comparisons between the 2 procedures. The most common adverse event was pain, reported mainly by older children after BM harvest, but also observed after central venous catheter (CVC) placement for PBSC collection. With regard to severe adverse events, one patient (0.7%) developed a pneumothorax with hydrothorax after CVC placement for PBSC collection. The risk of allotransfusion after BM harvest was associated with a donor age of < 4 years and a BM harvest volume of > 20 mL/kg. Children < 4 years were at higher risk than older children for allotransfusion after BM harvest and there was a higher risk of complications from CVC placement before apheresis. We conclude that PBSC and BM collection are safe procedures in children.

[18F]Fluorodeoxyglucose positron emission tomography for detection of bone marrow involvement in children and adolescents with Hodgkins lymphoma.
J. Clin. Oncol.
PUBLISHED: 08-08-2011
Show Abstract
Hide Abstract
Currently, a routine bone marrow biopsy (BMB) is performed to detect bone marrow (BM) involvement in pediatric Hodgkins lymphoma (HL) stage greater than IIA. [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET) is increasingly used for the initial staging of HL. The value of using FDG-PET to detect BM involvement has not been sufficiently defined. We compared the results of BMBs and FDG-PET for the diagnosis of BM involvement in a large pediatric group with HL.

Molecular diagnosis of Shwachman-Diamond syndrome in a child with incomplete clinical disease phenotype.
Pediatr Blood Cancer
PUBLISHED: 05-21-2010
Show Abstract
Hide Abstract
We report a 6-year-old female with congenital bone marrow failure, who was referred for allogeneic stem cell transplantation. An initial work-up in infancy had not revealed any consistent symptoms associated with an inherited syndrome. Computed tomography of her abdomen for gastrointestinal bleeding after transplantation incidentally revealed a fat-replaced pancreas and led to the molecular diagnosis of Shwachman-Diamond syndrome (SDS) in the absence of clinical exocrine pancreatic insufficiency. We conclude that SDS may escape the clinical consensus criteria for the disease. Increased awareness of unusual presentations may allow confirming the suspected diagnosis by molecular analysis and ensure optimal management.

Late graft failure in FA--case report and review of the literature.
Pediatr Transplant
Show Abstract
Hide Abstract
Hematological disorders in patients with FA can only be cured by allogeneic HSCT. Severe infections in primary and early secondary graft failures pose a particular risk. Whereas most graft failures occur within 100 days, those observed after day +100 are infrequent. Here, we present our analysis of a secondary graft failure more than five yr after a first allogeneic HSCT. In this patient, isolated thrombocytopenia over a period of 12 months resulted in a chimerism subset analysis revealing a considerable decrease in the CD34-positive donor cell fraction. After a second fludarabine-based preparative regimen, the patient received PBSC from the same donor. Chimerism returned to full donor in all subsets. This clinical course demonstrates that isolated thrombocytopenia can precede complete graft failure for several months. Our review of the literature on late graft failures in patients with FA after day +100 reveals the absence of fludarabine in the preparative regimen as a potential risk factor. Further clinical research is necessary to identify more suitable approaches for ensuring safe and stable engraftment.

Distinct mutations in STXBP2 are associated with variable clinical presentations in patients with familial hemophagocytic lymphohistiocytosis type 5 (FHL5).

Show Abstract
Hide Abstract
Familial hemophagocytic lymphohistiocytosis (FHL) is a genetically determined hyperinflammatory syndrome caused by uncontrolled immune response mediated by T-lymphocytes, natural killer (NK) cells, and macrophages. STXBP2 mutations have recently been associated with FHL5. To better characterize the genetic and clinical spectrum of FHL5, we analyzed a cohort of 185 patients with suspected FHL for mutations in STXBP2. We detected biallelic mutations in 37 patients from 28 families of various ethnic origins. Missense mutations and mutations affecting 1 of the exon 15 splice sites were the predominant changes detectable in this cohort. Patients with exon 15 splice-site mutations (n = 13) developed clinical manifestations significantly later than patients with other mutations (median age, 4.1 year vs 2 months) and showed less severe impairment of degranulation and cytotoxic function of NK cells and CTLs. Patients with FHL5 showed several atypical features, including sensorineural hearing deficit, abnormal bleeding, and, most frequently, severe diarrhea that was only present in early-onset disease. In conclusion, we report the largest cohort of patients with FHL5 so far, describe an extended disease spectrum, and demonstrate for the first time a clear genotype-phenotype correlation.

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.
