Current treatment options for spinal cord injury (SCI) are scarce. One of the most promising innovative approaches include gene-therapy, however no single gene has so far been shown to be of clinical relevance. This study investigates the efficacy of various combinations of vascular endothelial growth factor (VEGF), glial cell-derived neurotrophic factor (GDNF), angiogenin (ANG) and neuronal cell adhesion molecule (NCAM) in rats. Multiple therapeutic genes were administered intrathecally either via adenoviral vectors or by using genetically modified human umbilical cord blood mononuclear cells (hUCBMCs)...

BACKGROUND: Since the advent of neuromodulation, the role and efficacy of stereotactic radiosurgery (SRS) for chronic pain has not been carefully scrutinized. OBJECTIVE: To perform a systematic review to evaluate the clinical efficacy, both short- and long-term, of SRS for the treatment of chronic intractable pain. METHODS: A systematic search in PubMed, Web of Science, and PsycINFO was performed using keywords and controlled vocabulary. The search included peer-reviewed articles reporting clinical outcomes of SRS for chronic pain with a minimum 3-mo follow-up for nonmalignant and 1 mo for malignant pain...

We describe the case of a 41-year-old woman with metastatic cervical cancer and a large mass eroding into the pelvis and left lumbosacral plexus. The patient had intractable left lower extremity pain refractory to standard therapies, and she elected to undergo intrathecal neurolysis. A diagnostic intrathecal block was performed at the T11-12 interspace followed by intrathecal neurolysis with 6% phenol in glycerin on a subsequent date. During both procedures, we used a tilting radiolucent orthopedic fracture table to maintain strict left lateral-supine positioning...

PURPOSE: Existing anti-epileptic drugs (AED) have limited efficiency in many patients, necessitating the search for alternative approaches such as stem cell therapy. We report the use of autologous patient-derived mesenchymal stem cells (MSC) as a therapeutic agent in symptomatic drug-resistant epilepsy in a Phase I open label clinical trial (registered as NCT02497443). PATIENTS AND METHODS: The patients received either standard treatment with AED (control group), or AED supplemented with single intravenous administration of undifferentiated autologous MSC (target dose of 1×10(6)cells/kg), followed by a single intrathecal injection of neurally induced autologous MSC (target dose of 0...

Amyotrophic lateral sclerosis (ALS) is a degenerative motor neuron disease, causing muscle paralysis and death from respiratory failure. Effective means to preserve/restore ventilation are necessary to increase the quality and duration of life in ALS patients. At disease end-stage in a rat ALS model (SOD1(G93A)), acute intermittent hypoxia (AIH) restores phrenic nerve activity to normal levels via enhanced phrenic long-term facilitation (pLTF). Mechanisms enhancing pLTF in end-stage SOD1(G93A) rats are not known...

Percutaneous endoscopic gastrostomy (PEG) is the method of choice in patients requiring long-term enteral tube feeding. In patients with intrathecal baclofen infusion therapy (IBT) pump implantation, infection via the skin and soft tissue may be an issue of concern. The introducer technique for gastrostomy tube insertion may be useful in reducing the risk of peristomal infection. Although the presence of a PEG tube has been reported as a risk factor for implantation site infection (for newly inserted IBT pumps), whether existing IBT pumps are at risk for infection during or after the placement of a PEG tube is not clear...

BACKGROUND: Hyperbaric oxygen (HBO) has the potential to relieve neuropathic pain. The purpose of this study was to determine whether the NO-cGMP-PKG signaling pathway is involved in the analgesic effects of early hyperbaric oxygen treatment of neuropathic pain in rats. METHODS: Rats were randomly grouped for establishment of chronic constriction injury (CCI) models. Intrathecal catheters were inserted and 2.5ATA HBO therapy was administered from day 1 post-surgery for 60 minutes daily, continuously for 5 days; menstruum NS, DMSO, NO synthase(NOS) nonspecific inhibitor (L-NAME), soluble guanylyl cyclase(sGC) inhibitor (ODQ) and protein kinase G(PKG) inhibitor (KT5823) were administered intrathecally 30 minutes prior to HBO therapy...

Pichet Termsarasab, Steven J Frucht
Dystonic storm is a frightening hyperkinetic movement disorder emergency. Marked, rapid exacerbation of dystonia requires prompt intervention and admission to the intensive care unit. Clinical features of dystonic storm include fever, tachycardia, tachypnea, hypertension, sweating and autonomic instability, often progressing to bulbar dysfunction with dysarthria, dysphagia and respiratory failure. It is critical to recognize early and differentiate dystonic storm from other hyperkinetic movement disorder emergencies...

BACKGROUND: The delivery of intrathecal baclofen via pumps is gaining increasing use in the management of intractable spasticity. One of the rare but devastating complications of this method is infection. In the majority of cases, removal of the device is required, despite appropriate intravenous antibiotic therapy. We report a case that highlights the use of intrareservoir teicoplanin to achieve sterilization of the infected pump system in a patient in whom removal of the pump was not an easy option...

BACKGROUND: The prognostic impact of central nervous system (CNS) involvement in children with acute myeloid leukemia (AML) has varied in past trials, and controversy exists over the degree of involvement requiring intensified CNS therapy. Two recent Children's Oncology Group protocols, AAML03P1 and AAML0531, directed additional intrathecal (IT) therapy to patients with CNS2 (≤5 white blood cell [WBC] with blasts) or CNS3 (>5 WBC with blasts or CNS symptoms) disease at diagnosis...

The cerebrospinal fluid analysis has been employed for supporting multiple sclerosis diagnosis and ruling out the differential diagnoses. The most classical findings reflect the inflammatory nature of the disease, including mild pleocytosis, mild protein increase, intrathecal synthesis of immunoglobulin G, and, most typically, the presence of oligoclonal bands. In recent years, new biomarkers have emerged in the context of multiple sclerosis. The search for new biomarkers reflect the need of a better evaluation of disease activity, disease progression, and treatment efficiency...

Intrathecal baclofen therapy has become increasingly popular because of its effectiveness in treating spasticity in pediatric patients. The device implanted into each patient is structurally similar. However, x-ray imaging can give the appearance of missing or extraneous objects on or near the intrathecal baclofen device. The composition of the material used in making the catheters is transparent on x-ray images. In addition, the connection port between the pump and catheter resembles the shape of a needle...

BACKGROUND: Intrathecal drug delivery is an attractive option to circumvent the blood-brain barrier for pain management through its increased efficacy of pain relief, reduction in adverse side effects, and cost-effectiveness. Unfortunately, there are limited guidelines for physicians to choose infusion or drug pump settings to administer therapeutic doses to specific regions of the spine or the brain. Although empiric trialing of intrathecal drugs is critical to determine the sustained side effects, currently there is no inexpensive in vitro method to guide the selection of spinal drug delivery parameters...

Adeno-associated virus (AAV) gene therapy constitutes a powerful tool for the treatment of neurodegenerative diseases. While AAVs are generally administered systemically to newborns in preclinical studies of neurological disorders, in adults the maturity of the blood-brain barrier (BBB) must be considered when selecting the route of administration. Delivery of AAVs into the cerebrospinal fluid (CSF) represents an attractive approach to target the central nervous system (CNS) and bypass the BBB. In this study, we investigated the efficacy of intra-CSF delivery of a single-stranded (ss) AAV9-CAG-GFP vector in adult mice via intracisternal (iCist) or intralumbar (it-Lumb) administration...

A 30-year-old Vietnamese woman, about 19 weeks pregnant, was admitted for acute cerebral infarction with stenosis of the left middle cerebral artery (LMCA), tuberculous meningitis, and miliary tuberculosis. Treatment with heparin, quadruple anti-tuberculosis therapy, and dexamethasone afforded prompt symptomatic improvement. However, she delivered a stillbirth, after which there was recurrence of acute cerebral infarction with LMCA occlusion, sinus thrombosis, and cranial base inflammation. A thrice-weekly 100 mg dose of intrathecal isoniazid (INH) improved the signs of meningeal inflammation...
