Obesity following treatment of pediatric acute lymphoblastic leukemia (ALL) has become a significant long-term concern. Excessive weight gain often occurs during treatment, particularly during induction and the first 6 months of maintenance therapy, and it may be potentially modifiable. This retrospective study aimed to evaluate the impact of an early, 3-visit nutrition intervention on weight gain during maintenance therapy in ALL patients. Medical records of the intervention group were compared with historical controls who were treated on the same ALL treatment protocols during an earlier time period...

BACKGROUND: Oral mucositis can be a frequent and severe complication of chemotherapy in children. It can result in pain, infection, depression, prolonged admission, treatment delays, increase in patient morbidity, and increased costs. AIM: To record the prevalence and severity of oral mucositis among inpatients and explore the relationship of risks factors and the development of oral mucositis. DESIGN: During an 18-month period 643 clinical inpatient assessments were completed on 73 children who were admitted and had received chemotherapy in the last 14 days...

Invasive fungal infections are a serious cause of morbidity and mortality in patients with hematologic malignancies. Conidiobolus species are molds within the order Entomophthorales and may disseminate to become rapidly fatal in immunocompromised individuals. This species of fungal infections are often multidrug resistant (MDR) and present unique therapeutic challenges. Reports of Conidiobolus infections are rare in pediatric oncology. We report the successful treatment of an adolescent male with B-cell lymphoblastic leukemia and MDR invasive sinopulmonary Conidiobolus infection with emphasis on early and aggressive neutrophil support with surgical debridement...

Lymphoid interstitial pneumonia (LIP) is a rare disease characterized by benign reactive polyclonal proliferation of bronchus-associated lymphoid tissue after exposure to inhaled or circulating antigen(s), leading to a disease symptomatology similar to idiopathic interstitial pneumonia. Its association with diseases that are caused due to immune dysregulation (autoimmune diseases, congenital/acquired immunodeficiency, and allogeneic bone marrow transplant) and response to immunomodulatory/suppressive medications suggests an immunologic pathophysiology...

We present the case of a woman referred to our department at 34 weeks of pregnancy with a fetal ultrasonographic scan showing a mass that had developed within the right maxilla with invasion of the orbit. A retrospective examination showed that this tumor had been present since the 12th week of pregnancy. At 39+4 weeks of gestation, a boy was born. He presented a black firm aspect in the maxilla. A computed tomographic scan and magnetic resonance imaging revealed a soft tissue swelling over the right maxilla, extending into the orbit but without invasion of the globe...

Central venous catheters (CVCs) in neonates are associated with an increased risk of thrombosis. Most reports focus on umbilical venous catheters (UVCs) and peripherally inserted central catheters (PICCs), whereas data available on femoral venous catheters (FVCs) are limited. We performed a retrospective cohort study in all neonates (gestational age ≥34 wk) with CVCs. The primary outcome was the occurrence of thrombosis in CVCs. The secondary outcomes were possible risk factors for thrombosis, the thrombotic incidence in FVCs, UVCs, and PICCs, and clinical aspects of thrombosis in these groups...

Pediatric lung cancer is a very rare occurrence, particularly as a primary lesion. A concurrent diagnosis is even more unusual and only reported a handful of times in Ewing sarcoma. Our patient is a 13-year-old boy who had concurrent diagnoses of Ewing sarcoma and minimally invasive adenocarcinoma of the lung, formerly bronchoalveolar carcinoma. To our knowledge this has also been found in at least 1 other case. There are some classic genetic mutations associated with Ewing sarcoma. None have been found to be linked with the concurrent diagnosis...

BACKGROUND: Patients with chronic graft-versus-host disease (cGVHD) following allogeneic transplant for myeloid leukemias seem to experience a reduced risk of relapse than comparable patients without cGVHD. It is unclear to what extent extramedullary sites are impacted by a graft-versus-leukemia effect. DESIGN/METHOD: Case Series and review of the literature. RESULTS: We present 2 cases of pediatric patients with Acute Myelogenous Leukemia who developed isolated testicular relapse more than a year following hematopoietic stem cell transplantation despite having had extensive cGVHD...

Pleuropulmonary blastoma (PPB) is a rare malignancy of childhood which when left untreated often shows pathologic progression resulting in a more aggressive neoplasm with an increasingly poor prognosis. Because of this it is important to diagnose and initiate treatment early. However, early stage PPB can appear as a cystic lung lesion on imaging and can be easily misdiagnosed given the rarity of the malignancy. Moreover, current therapeutic guidelines for these lesions are not well established, making treatment decisions and management difficult for clinicians...

Priorities for young adult survivorship care from the survivors' perspective are not well documented. To address this within our patient population, we conducted a multimethod needs assessment of young adult survivors of pediatric, adolescent, and young adult cancer in South Texas to get a better understanding of the ongoing challenges and priorities for their survivorship needs and related services. Participants were 18 to 39 years at the time of the needs assessment and predominately Hispanic. In an online survey, survivors most commonly cited being concerned about their physical and mental health, long-term treatment effects, recurrence, and health insurance issues...

Chemotherapy-associated myelosuppression and renal dysfunction is not uncommon during childhood acute lymphoblastic leukemia (ALL) therapy. Here we report 2 cases of atypical hemolytic uremic syndrome (aHUS) presenting with pancytopenia and renal dysfunction that developed during maintenance chemotherapy characterized by hypocomplementemia. Both cases experienced recurrence after resolution of the initial aHUS episode upon resumption of chemotherapy, raising a possible contributory role for chemotherapy in the disease pathogenesis...

We present a case of a 2-year-old female presenting with diffuse lymphadenopathy 2 years following orthotopic heart transplant. Initially, she was diagnosed with posttransplant lymphoproliferative disease based on clinical presentation and pathology and she was treated accordingly. Because of persistent lymphadenopathy following the completion of chemotherapy and new onset of autoimmune cytopenias, repeat flow of the lymph node showed an elevated double negative T-cell population prompting evaluation for autoimmune lymphoproliferative syndrome (ALPS)...

Complement system dysregulation, such as complement Factor H (CFH) autoantibodies and deletions in CFH-related (CFHR) genes 3 and 1, might cause transplant-associated thrombotic microangiopathy (TA-TMA). The use of eculizumab, a terminal complement inhibitor, could be a targeted therapy for TA-TMA. We report a 1-year-old girl who developed TA-TMA, just after autologous peripheral blood stem cell transplantation in neuroblastoma therapy. Eculizumab improved TA-TMA. Investigation for the complement alternative pathway showed a heterozygous CFHR3-CFHR1 gene deletion, which is involved in complement activation...

Children with acute lymphoblastic leukemia or lymphoma (ALL) undergo multiple lumbar punctures (LPs) and frequently require low-molecular-weight heparin (LMWH) for thromboembolic complications. We evaluated if withholding LMWH 24 hours before and after LPs prevented bleeding complications. Children (n=133) with ALL from who were: (1) treated at St. Jude Children's Research Hospital, (2) received LMWH (2×/day of ~1 mg/kg) between January 2004 until December 2012, and (3) underwent a LP were analyzed. Spinal hematoma was defined as a clinical suspicion leading to diagnostic imaging...

BACKGROUND: Pericardial effusion (PE) is a known complication after hematopoietic stem cell transplant (HSCT). Limited data is currently available regarding the incidence and outcomes of PE in pediatric HSCT. METHODS: We conducted a retrospective study on a cohort of patients who underwent HSCT between 2004 and 2015. Risk factors associated with development of PE were evaluated. RESULTS: In 111 HSCT, stem cell source was bone marrow in 37 (33...

INTRODUCTION: Childhood acute leukemias (AL) and lymphomas achieve good survival rates. However, second neoplasms (SN) are a devastating event. METHODS: From August 1987 to December 2016, 34 of 3321 (1%) patients with diagnosis of AL or lymphoma developed SN. SN were AL (n=16), CNS tumors (n=5), endocrinal tumors (n=3), lymphomas (n=2), schwannoma (n=2) assorted sarcomas (n=4), retinal melanoma (n=1), and Vanek tumor (n=1). Median latency was 51 (range, 10 to 110) months for hematological malignancies and 119 (range, 25 to 236) months for solid tumors (P=0...

Venous thromboembolism can be precipitated by both genetic and acquired factors, but the role of testosterone therapy is less clear. Here, we present a 17-year-old transgender adolescent, transitioning from female to male, receiving both estrogen and testosterone therapy, who developed a pulmonary embolism without an underlying genetic thrombophilic condition. As transgender medical care evolves, the use of testosterone as cross-sex hormone therapy in adolescents is likely to increase. Our review suggests that care must be taken when initiating treatment with testosterone, and modification of other thrombophilic risks should be explored before starting therapy in this population...
