RESUMEN
Fibroblast growth factor receptor (FGFR) tyrosine kinase inhibitors (TKIs) are increasingly being used off label in pediatrics. Long-term safety data are limited, and serious toxicities unique to pediatrics may emerge. In a retrospective analysis of patients less than 18 years of age with recurrent/refractory FGFR altered gliomas treated with FGFR TKIs at MSKCC (n = 7), we observed slipped capital femoral epiphyses in three of seven patients along with increased linear growth velocity. Clinicians should closely monitor bone health and have a low index of suspicion for serious orthopedic complications including slipped capital femoral epiphyses and inform patients of related risks as part of consent when treating with FGFR TKIs.
RESUMEN
OBJECTIVE: To analyze the relation between platelet counts, intensities of physical therapy (PT) and occupational therapy (OT) services received, and frequencies of bleeding complications in children undergoing hematopoietic stem cell transplant (HSCT) during a period of severe thrombocytopenia. DESIGN: Retrospective review study. SETTING: Tertiary care hospital. PARTICIPANTS: Children (N=63; age, <18y) hospitalized for HSCT in 2010 and 2011 who received PT and OT services while markedly thrombocytopenic (platelet count, ≤50K/mcL). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Intensities of PT and OT interventions, patients' platelet counts on specific therapy days, and any bleeding events (minor or major) that occurred during or shortly after rehabilitation interventions. RESULTS: Sixty-two patients (accounting for 63 HSCTs) met the criteria for analysis. Fifty-six of these patients (57 HSCTs) underwent PT and/or OT while markedly thrombocytopenic. There was no correlation between platelet counts and intensities of rehabilitation interventions. There were no major bleeding events. There was no association between minor bleeding events and intensities of PT or OT interventions and no association between minor bleeding events and platelet counts. Only 5 minor bleeding events occurred during or after moderate or intensive therapy out of 346 PT and OT sessions (1.5%). CONCLUSIONS: The results of our study suggest that bleeding complications during or after mobilization and supervised exercise during PT and OT in children with severe thrombocytopenia undergoing HSCT are minor and relatively rare. These are encouraging results for both patients and rehabilitation specialists treating this population who is at high risk of developing immobility-related complications.

OBJECTIVE The object of this study was to determine the percentage of high-dose (1800-2600 cGy) single-fraction stereotactic radiosurgery (SF-SRS) treatments to the spine that result in peripheral nervous system (PNS) injury. METHODS All patients treated with SF-SRS for primary or metastatic spine tumors between January 2004 and May 2013 and referred to the Rehabilitation Medicine Service for evaluation and treatment of neuromuscular, musculoskeletal, or functional impairments or pain were retrospectively identified. RESULTS Five hundred fifty-seven SF-SRS treatments in 447 patients resulted in 14 PNS injuries in 13 patients. All injures resulted from SF-SRS delivered to the cervical or lumbosacral spine at 2400 cGy. The overall percentage of SF-SRS treatments resulting in PNS injury was 2.5%, increasing to 4.5% when the thoracic spine was excluded from analysis. The median time to symptom onset following SF-SRS was 10 months (range 4-32 months). The plexus (cervical, brachial, and/or lumbosacral) was affected clinically and/or electrophysiologically in 12 (86%) of 14 cases, the nerve root in 2 (14%) of 14, and both in 6 (43%) of 14 cases. All patients experienced pain and most (93%) developed weakness. Peripheral nervous system injuries were CTCAE Grade 1 in 14% of cases, 2 in 64%, and 3 in 21%. No dose relationship between SF-SRS dose and PNS injury was detected. CONCLUSIONS Single-fraction SRS to the spine can result in PNS injury with major implications for function and quality of life.

We report a severe and not previously reported toxicity after short-interval retreatment with stereotactic body radiotherapy (SBRT) in a pediatric patient with neuroblastoma. This patient experienced Grade III radiation myositis after treatment with conventional radiation therapy followed by high-dose SBRT for persistent disease a short interval after the initial radiotherapy course. While SBRT shows outstanding rates of local control in adult disease, data in pediatric cancers are extremely limited. In this report, we discuss the rationale of SBRT in this patient's multimodality neuroblastoma treatment, management of the toxicity, and future perspectives on the use of SBRT in pediatric cancer.

INTRODUCTION: Lymphedema has long been considered a risk factor for median nerve compression at the wrist and carpal tunnel syndrome (CTS). This association is based on limited and poor quality data. We analyzed the association between lymphedema and CTS. METHODS: Breast cancer survivors with upper extremity lymphedema and electrophysiologically confirmed CTS were assessed retrospectively. The severity of lymphedema was graded using the National Institutes of Health Common Terminology Criteria for Adverse Events (CTCAE) v4.03. The severity of CTS was graded in accordance with accepted criteria. RESULTS: Nineteen patients (38 sides) met the criteria for analysis. There was no association between presence of lymphedema and CTS (P = 0.66) or between lymphedema severity and CTS severity (P = 0.79). There were no cases of infection or worsening lymphedema as a result of needle EMG. CONCLUSIONS: These findings do not support lymphedema as an etiologic factor in the pathogenesis of CTS.

Steroids are broadly used in oncology, despite known adverse events such as glucocorticosteroid-induced myopathy (SM). To date there are no accepted guidelines on the diagnosis and treatment of SM. The purpose of this review is to provide up-to-date information regarding SM with emphasis on neuro-oncology and hematopoietic stem cell transplant patients, given they are at high risk of experiencing SM following routine treatment with steroids. Our work is a combination of a comprehensive narrative review regarding etiology, pathogenesis, incidence, clinical presentation and treatment options for SM and a scoping review on exercise therapy for SM. We have identified 24 in vivo studies of different exercise modalities in the settings of glucocorticosteroid treatment. Twenty of 24 studies demonstrated decreased muscle catabolism with exercise training. Both endurance and resistance exercises at mild to moderate intensity were beneficial. The value of high-intensity activities remains questionable as it may worsen muscle atrophy. Rehabilitation interventions, along with pharmacologic and dietary considerations, may be beneficial in preventing or reversing SM. Potential adverse events of some of these interventions and expected caveats in translating findings in preclinical models to human settings warrant caution and demand controlled clinical studies.

Objectives: Delirium, an acute change in mental state, seen in hospitalized older adults is a growing public health concern with implications for both patients and caregivers; however, there is minimal research on educating caregivers about delirium. Utilizing family caregivers to assist with delirium management in acute care settings demonstrates improved health outcomes supporting the need for patient and family centered care. The primary aims of the study were to determine feasibility of implementing a delirium education video for caregivers of patients in an adult oncology intensive care unit and compare delirium knowledge to caregivers in a control group. Methods: A quasi-experimental design comprised of 31 family caregivers of adult patients in an oncology intensive care unit to determine feasibility of implementing a delirium education video. Results: The results demonstrate feasibility of implementing a caregiver education video in-person and virtually. While total delirium knowledge scores were not statistically significant, knowledge gained within the delirium presentation subgroup was significant (p = .05). Conclusion: This study demonstrates feasibility of implementing a caregiver education video and findings support further research in this area. Innovation: Collaborating with caregivers to develop virtual video education for delirium allows for a versatile approach to connect with caregivers to support their caregiving role.
