BACKGROUND: Central venous access devices (CVADs) are essential for total parenteral nutrition administration in patients with short bowel syndrome (SBS). However, they are fraught with complications including infection and venous thromboembolism (VTE), which increases associated morbidity and mortality in this population. There is evidence linking the development of CVAD-associated thrombosis and line-related infection. Thus, it has been postulated that prevention of catheter-related clot formation could minimize the risk of infection originating from the catheter...

Isolated MYC rearrangement without other recurrent genetic abnormalities is rare in B lymphoblastic leukemia/lymphoma (B-ALL/LBL), with most cases reported in pediatric patients. We report 3 adult cases with lymphoblasts showing a precursor B cell immunophenotype, and isolated MYC/IGH translocation. All 3 cases occurred in male patients with initial presentation of diffuse lymphadenopathy. Cases 1 and 2 had B-ALL with significantly increased lymphoblasts in peripheral blood and bone marrow. Case 3, a patient with human immunodeficiency virus infection, had the diagnosis of B-LBL made on a retroperitoneal lymph node biopsy and had no peripheral blood or bone marrow involvement...

FGFR1 translocation may cause myeloid or lymphoid neoplasm but rarely systemic mastocytosis (SM). Conversely, SM is associated with myeloproliferative neoplasm (MPN), but rarely lymphoblastic lymphoma (LBL) or FGFR1 translocation. We report the first case of FGFR1 translocation in a patient with concurrent LBL, MPN, and SM. A 21-year-old male patient presented with diffuse lymphadenopathies and leukocytosis. TdT(+)/cytoCD3(+)/CD79a(weakly+) LBL was identified in the lymph node. Bone marrow had MPN, SM, and TdT(+)/CD79a(+)/cytoCD3(weakly+) LBL...

BACKGROUND: Women with chest pain, ischemia, and no obstructive coronary artery disease often have coronary vascular dysfunction (CVaD). Peripheral vascular reactivity to mental stress may contribute mechanistic understanding of stress-induced ischemia in women with CVaD. METHODS: 62 women (41 CVaD and 21 controls) underwent mental stress testing (MST) with anger recall, mental arithmetic, and forehead cold pressor (COP) challenge. Emotional arousal was measured (Likert scale)...

While rare, cases of isolated extramedullary disease of B-cell Lymphoblastic Lymphoma (B-LBL) without morphologic bone marrow involvement have been described. In this report, we illustrate the case of an elderly gentleman who presented with isolated testicular and vertebral LBL involvement but had no morphologic bone marrow involvement. The initial plan of treatment was to treat along the lines of Philadelphia negative B-ALL/LBL. During this time, fluorescence in situ hybridization (FISH) and PCR testing for BCR-ABL1 rearrangements were being performed on the marrow specimens as a part of routine diagnostic workup...

Nelarabine, a water soluble prodrug of 9-β-D-arabinofuranosylguanine (ara-G), is a T-cell specific purine nucleoside analogue. Given its activity in relapsed and refractory T acute lymphoblastic leukemia (T-ALL) and T lymphoblastic lymphoma (T-LBL), we sought to define its role in the frontline treatment of adult patients. Therefore, we conducted a single arm phase 2 study to determine the safety and efficacy of nelarabine in combination with hyper-CVAD in newly diagnosed patients. For induction/consolidation, patients received eight cycles of hyper-CVAD alternating with high-dose methotrexate and cytarabine plus two cycles of nelarabine given at a dose of 650 mg/m(2) intravenously daily for 5 days...

Lymphoblastic lymphomas are neoplasms of immature or precursor lymphoid cells with no or limited bone marrow involvement, whose clinical presentation varies according to the immunophenotype. While mediastinal involvement is predominant in T-lymphoblastic lymphomas, B-lymphoblastic lymphomas frequently involve nodal sites. Extranodal presentation of B-lymphoblastic lymphomas is extremely rare. We present the case of a 49-year-old man with B-lymphoblastic lymphoma of the hard palate. The patient was treated with the R-Hyper CVAD regimen and is on maintenance chemotherapy...

Diffuse large B cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL), accounting for approximately 25% of NHL cases. It is a heterogeneous group of diseases. BCL2, BCL6, and MYC are the most frequent mutated genes in DLBCL. Double-hit lymphoma (DHL) is an aggressive form of DLBCL with an unmet treatment need, in which MYC rearrangement is present with either BCL2 or BCL6 rearrangement. Patients typically present with a rapidly growing mass with B symptoms. DHL has been linked to very poor outcomes when treated with RCHOP chemotherapy...

AIMS: Acute lymphoblastic leukemia (ALL) is an aggressive form of leukemia with a poor prognosis in adult patients. The addition of the monoclonal antibody rituximab to standard chemotherapy has been shown to improve survival in adults with ALL. However, it is unknown whether the addition of rituximab is cost-effective. The objective was to determine the economic impact of rituximab in addition to standard of care (SOC) chemotherapy vs SOC alone in newly-diagnosed Philadelphia chromosome-negative, CD20-positive, B-cell precursor ALL...

INTRODUCTION: The peripherally inserted central catheters (PICCs) are vascular access devices (VAD) that are increasingly being used in the pediatric population. If a small vein caliber prevents positioning the catheter in the arm, the following step is to position the same catheter in the supraclavicular area, which can be defined as an off-label use or "atypical" approach, first described by Pittiruti. MATERIALS AND METHODS: We retrospectively reviewed PICC positioning with puncture-site in the supra-clavicular area ("atypical" PICC insertion) and then tunneled on the chest...

Central venous access devices (CVADs) form an important component of modern paediatric healthcare, especially for children with chronic health conditions such as cancer or gastrointestinal disorders. However device failure and complications rates are high.Over 2½ years, a child requiring parenteral nutrition and associated vascular access dependency due to 'short gut syndrome' (intestinal failure secondary to gastroschisis and resultant significant bowel resection) had ten CVADs inserted, with ninesubsequently failing...

Sarah Hess, Mary Decker
The discard technique is the most widely used method of obtaining blood samples from patients with central venous access devices (CVADs), but risks removing more blood than is necessary for laboratory testing and may increase a patient's risk of anemia. We hypothesized that laboratory results from pediatric blood specimens obtained via CVAD using the single-syringe push-pull (formerly called the mixing) method and the discard method would be similar. Blood samples were obtained from pediatric oncology patients in a hospital setting using both collection methods and laboratory values were analyzed for concordance using the pairwise t-test, intraclass correlation coefficient, and Bland-Altman analysis methods...
