OBJECTIVE: Leptomeningeal metastasis (LM) leades a devastating consequence in patients with nonsmall cell lung cancer(NSCLC). Treatment is very limited for patients with LM. We introduced to use nimotuzumab (also known as h-R3) combined with methotrexate for treating LM in NSCLC patients. PATIENTS AND METHODS: In the present report, twenty patients with LM of NSCLC were included, and the clinicopathology information and outcomes after treatment were analyzed. RESULTS: All the twenty patients with LM were lung adenocarcinoma...

PURPOSE OF REVIEW: Acute and chronic leukemias are heterogeneous diseases and can affect any part of the body upon initial discovery. Understanding the sequela of systemic involvement is key for proper diagnosis and treatment. RECENT FINDINGS: Over the decades, new research has emerged regarding neurological complications of the myeloid or lymphoid leukemias. Central nervous system involvement usually confers a poor prognosis and requires emergent treatment. Standard of care still involves systemic therapy, intrathecal administration of chemotherapeutic agents, and cranial radiation...

Currently, in clinical practice there is no efficient way to overcome the sequences of neurodegeneration after spinal cord traumatic injury. Using a new experimental model of spinal cord contusion injury on miniature pigs, we proposed to deliver therapeutic genes encoding vascular endothelial growth factor (VEGF), glial cell line-derived neurotrophic factor (GDNF) and neural cell adhesion molecule (NCAM) to the damaged area, using umbilical cord blood mononuclear cells (UCBC). In this study, genetically engineered UCBC (2×10(6) cells in 200 ml of saline) were injected intrathecally to mini-pigs 10days after SCI...

BACKGROUND: Long-term opioid therapy for chronic pain may lead to analgesic tolerance, especially when administered intrathecally, thus preventing adequate pain relief. Discovering drug targets to treat opioid tolerance using a mechanism-based approach targeting opioid-induced neuroinflammation provides new therapeutic opportunities. In this study, we provide translational evidence that CXCL12/CXCR4 signaling contributes to the pathogenesis of opioid tolerance. METHODS: The CXCL12 levels in the cerebrospinal fluid of opioid-tolerant patients were compared with those of opioid-naive subjects...

Mucopolysaccharidosis type I (MPS I) is an inherited lysosomal storage disease that seriously affects the brain. Severity of neurocognitive symptoms in attenuated MPS subtype (MPS IA) broadly varies partially, due to restricted permeability of blood-brain barrier (BBB) which limits treatment effects of intravenously applied α-L-iduronidase (rhIDU) enzyme. Intrathecal (IT) rhIDU application as a possible solution to circumvent BBB improved brain outcomes in canine models; therefore, our study quantifies effects of IT rhIDU on brain structure and function in an MPS IA patient with previous progressive cognitive decline...

Patients with primary central nervous system lymphoma (PCNSL) treated in the 'real-world' setting do not represent those treated on clinical trials and might not be treated similarly. We studied characteristics and variability in care for 113 newly diagnosed PCNSL patients treated at 5 institutions in the Chicago area between 2000 and 2012. In 111 patients, single modality therapy with a high dose methotrexate (HD-MTX) regimen +/- rituximab, was most commonly employed (n = 65), and 34 underwent radiotherapy (+/- systemic therapy)...

Intrathecal baclofen(ITB)is used to treat intractable spasticity of various etiologies and can provide better control of spasticity through the adjustment of the dose administered through the pump. However, in patients who develop tolerance to baclofen with the standard simple continuous mode, a sharp increase in dose becomes necessary, and spasticity can become harder to control. We investigated whether switching from the simple continuous mode to the bolus infusion mode was effective in controlling spasticity in patients with baclofen tolerance...

BACKGROUND: Substance P (SP) is produced at high levels in the central nervous system (CNS), and its target receptor, neurokinin 1 receptor (NK-1R), is expressed by glia and leukocytes. This tachykinin functions to exacerbate inflammatory responses at peripheral sites. Moreover, SP/NK-1R interactions have recently been associated with severe neuroinflammation and neuronal damage. We have previously demonstrated that NK-1R antagonists can limit neuroinflammatory damage in a mouse model of bacterial meningitis...

We report a case of deliberate intrathecal catheter insertion and removal in the setting of continuous dual-antiplatelet therapy with clopidogrel and aspirin. A patient with recently sited bare metal intracerebral stents developed severe symptomatic hydrocephalus and required temporary cerebrospinal fluid diversion. The risks of intracerebral in-stent thrombosis or delayed intervention precluded following guidelines for the management of clopidogrel in neuraxial procedures. Options to mitigate the risk of and facilitate the early detection of epidural hematoma are discussed when neuraxial instrumentation is indicated in the setting of clopidogrel and aspirin therapy...

: 102 Background: Intrathecal pumps (ITP) are used to manage severe malignancy related pain by delivering analgesics directly into the cerebrospinal fluid, in theory allowing for a reduced opioid dose and fewer complications. Although there is literature to support efficacy in patients with cancer, including improved survival, this mode of drug delivery also carries a risk of serious complications. Reports of complications in non-malignant pain suggest the risks and mortality related to ITP may be under-appreciated and that injury and liability occur with both ITP placement and ITP maintenance...

OBJECTIVE Medically refractory spasticity and dystonia are often alleviated with intrathecal baclofen (ITB) administration through an indwelling catheter inserted in the lumbar spine. In patients with cerebral palsy, however, there is a high incidence of concomitant neuromuscular scoliosis. ITB placement may be technically challenging in those who have severe spinal deformity or who have undergone prior instrumented thoracolumbar fusion. Although prior reports have described drilling through the lumbar fusion mass with a high-speed bur, as well as IT catheter implantation at the foramen magnum or cervical spine, these approaches have notable limitations...

Central nervous system (CNS)-hemophagocytic lymphohistiocytosis (HLH) is not a disease in itself, but it is part of a systemic immune response. The vast majority of patients with CNS-HLH also have systemic HLH and a large number of patients with primary and secondary HLH have CNS involvement. Reactivations within the CNS are frequent during the course of HLH treatment and may occur concomitant with or independent of systemic relapses. It is also important to consider primary HLH as an underlying cause of "unknown CNS inflammation" as these patients may present with only CNS disease...

: 206 Background: Delays in administration of planned in-patient chemotherapy can lead to prolonged length of stay (LOS), resulting in increased cost and risk of nosocomial infections and other complications. METHODS: We conducted a retrospective analysis of cancer patients admitted to Columbia University Medical Center, a tertiary care center, for planned chemotherapy from January 1, 2014 through December 31, 2014. Eligible patients were identified as cancer patients (via ICD9 codes) who were admitted directly to the inpatient hematology/oncology service with intravenous chemotherapy orders submitted within 24 hours of the admission...

BACKGROUND: Cell-based therapies are a promising treatment option for traumatic, tumorigenic and degenerative diseases of the spinal cord. Transplantation into the spinal cord is achieved with intravascular, intrathecal, or direct intraparenchymal injection. The current standard for direct injection is limited by surgical invasiveness, difficulty in reinjection, and the inability to directly target anatomical or pathological landmarks. The objective of this study was to present the proof of principle for minimally invasive, percutaneous transplantation of stem cells into the spinal cord parenchyma of live minipigs under MR guidance...

Leptomeningeal dissemination of paraganglioma is rare, with only 2 prior cases in the literature. The authors present the case of a metastatic low-grade lumbar paraganglioma via leptomeningeal dissemination. This report emphasizes the utility of 3,4-dihydroxy-6-(18)F-fluoro-l-phenylalanine ((18)F-FDOPA) PET scanning for diagnosis, as well as the combination of radiation therapy and alkylating chemotherapeutic agents for the treatment of this rare phenomenon. The patient was a 61-year-old woman who presented with low-back pain and was found to have an isolated L-3 intrathecal tumor on MRI...

BACKGROUND: Families often express a need for additional information about neurocognitive late effects (NCLE) after a pediatric cancer diagnosis. Therefore, we examined: (i) differences in parent, child, and oncologist estimates of risk for NCLE; (ii) whether the estimates of parents and/or children change over time; and (iii) whether estimates are different for children treated with central nervous system (CNS) directed therapies. PROCEDURE: Mothers, fathers, and children (initial age: 5-17, self-report: >10) from 258 families reported their perceived likelihood of the child developing "thinking/learning problems" on a visual analog scale (0-100%) at 2 months (T1), 1 year (T2), and 3 years (T3) following cancer diagnosis/relapse...

Leptomeningeal metastasis is a fatal manifestation seen in advanced cancer patients. Its incidence is increasing, reaching 3.8% in molecularly unselected non-small cell lung cancer patients and up to 5% and 9% in ALK-rearranged and EGFR-mutant lung cancer patients, respectively. The prognosis remains poor despite systemic treatment, intrathecal chemotherapy, radiation therapy and personalized treatments in molecularly selected patients. However, new therapies with improved cerebral-spinal fluid penetration have been developed for subgroups of molecular selected patients indicating they could be promising therapeutic options for managing leptomeningeal disease...

Most of the current therapies, as well as many of the clinical trials, for multiple sclerosis (MS) target the inflammatory autoimmune processes, but less than 20% of all clinical trials investigate potential therapies for the chronic progressive disease stage of MS. The latter is responsible for the steadily increasing disability in many patients, and there is an urgent need for novel therapies that protect nervous system tissue and enhance axonal growth and/or remyelination. As outlined in this review, solid pre-clinical data suggest neutralization of the neurite outgrowth inhibitor Nogo-A as a potential new way to achieve both axonal and myelin repair...

We report two patients in whom the intrathecal baclofen(ITB)catheter was located in the subdural space, although we had confirmed good outflow of spinal fluid from the spinal catheter. Patient 1 was a woman in her 30s with spastic quadriplegia due to subarachnoid hemorrhage. An ITB pump was implanted, and a good outflow of spinal fluid from the spinal catheter was observed during the surgery. Postoperatively, her spasticity did not improve. Catheter myelography revealed that the spinal catheter was located in the subdural space...
