Revisiting The Expanded Use Of Hyperbaric Oxygen Therapy For Treatment Of Resistant Migraines, David V Matera, Brian Smith, Benjamin Lam Oct 2019

Revisiting The Expanded Use Of Hyperbaric Oxygen Therapy For Treatment Of Resistant Migraines, David V Matera, Brian Smith, Benjamin Lam

PCOM Scholarly Works

There are currently 13 indications approved by the U.S. Food and Drug Administration for use of hyperbaric oxygen therapy. The European Consensus Conference on Hyperbaric Medicine has 28 indications approved for its use. However, neither includes the use of hyperbaric oxygen therapy for neurological conditions such as migraines with aura. Recent research has made the attempt to fully understand the use of hyperbaric therapy in treatment of neurological conditions, but results have so far been inconclusive. We report a 23-year-old female with an 11-year history of migraines with aura who has received inadequate pharmacological treatment for her migraines since she …

Articles, Abstracts, and Reports

Lumbar spinal stenosis is defined as narrowing of the lumbar spinal canal, which causes compression of the spinal cord and nerves. Spinal stenosis can cause leg pain and potentially back pain that can affect the quality of life. Ultimately, surgical decompression is required to alleviate the symptoms. In this review, we first utilize several important studies to compare lumbar laminectomy alone versus lumbar laminectomy and fusion. We also compare the effectiveness of more novel surgical approaches, stand-alone anterior lumbar interbody fusion (ALIF), and stand-alone lateral lumbar interbody fusion (LLIF). These techniques have their own advantages and disadvantages in which many …

Post-Dural Puncture Headache Complicated By Subdural Hematomas - A Case Report, Mark Cohen Md, Mays Alani Md, Amir Touray Md, Saif Ullah Md

Neurology

Post-dural puncture headache (PDPH) is a potential iatrogenic complication of procedures which disrupt meningeal integrity, particularly in obstetric patients, which are perhaps the highest-risk group. Common clinical manifestations include severe diffuse headache, neck stiffness, and nausea and vomiting; these symptoms, however, are non-specific and PDPH remains a diagnosis of exclusion that can be ascertained with a thorough history and proper consideration of other etiologies.

Neurotoxicity In A Young Patient With Diffuse Large B-Cell Lymphoma After First Dose Of Intrathecal Triple Therapy., Ali Sajjad, Sajid Hameed, Sara Khan

Pakistan Journal of Neurological Sciences (PJNS)

Intrathecal triple chemotherapy (ITT) including cytarabine arabinoside, methotrexate and glucocorticoids is a standard regimen for prophylaxis and treatment of hematological malignancies, owing to their high proclivity for invasion of the neuraxis. Unfortunately, intrathecal chemotherapy is associated with various neurological adverse effects including seizures, encephalopathy, myelopathy, arachnoiditis and cauda/conus syndrome. We present a case of 33-year-old lady with primary bone diffuse large B-cell lymphoma. She had received 4 cycles of R-CHOP* and later 2 cycles of R-DHAP**. The first dose of ITT was administered along with the last cycle of R-DHAP. On the third day post-ITT, she developed acute bilateral lower …

Extended Window Intravenous Thrombolysis: Is Conventional Window Of 4.5 Hours Coming To An End?, Malik Muhammad Adil, Narmeen Masood

Pakistan Journal of Neurological Sciences (PJNS)

The current standard of care to treat acute stroke patients presenting within 4.5 hours of stroke symptom onset is intravenous (IV) Alteplase.1 Over the past decade, tremendous efforts have been made to challenge the conventional window of 4.5 hours for the administration of Alteplase to expand the patient population which can benefit from thrombolysis. Based on the recent meta-analysis, 2 we have strong evidence supporting the use of IV thrombolysis in patients presenting between 4.5 to 9 hours of symptom onset with favorable perfusion imaging and it appears that the era of the conventional 4.5 hours window may be coming …

Post-Stroke Seizures: A Clinically Oriented Analysis, Sajid Hameed, Haris Hakeem, Mohammad Wasay

Pakistan Journal of Neurological Sciences (PJNS)

Stroke is an important cause of secondary epilepsy, especially in the elderly. Not only does this impact morbidity and mortality in an adverse way, it also prolongs the hospitalization. Various risk factors have been described in literature that increase the risk of seizures in a patient with stroke. Post stroke seizures fall on a spectrum of acute symptomatic and unprovoked seizures with varying pathophysiology and risk of subsequent development of epilepsy. Hence, the treatment approaches are also different. However, randomized controlled trials are lacking to guide monitoring and management strategies in post stroke seizures and the approaches remain individualized to …

Diabetes-Related Amylin Dyshomeostasis: A Contributing Factor To Cerebrovascular Pathology And Dementia, Han Ly, Florin Despa Sep 2019

Diabetes-Related Amylin Dyshomeostasis: A Contributing Factor To Cerebrovascular Pathology And Dementia, Han Ly, Florin Despa

Pharmacology and Nutritional Sciences Faculty Publications

Type 2 diabetes (T2D) increases the risk for cerebrovascular disease (CVD) and dementia. The underlying molecular mechanisms remain elusive, which hampers the development of treatment or/and effective prevention strategies. Recent studies suggest that dyshomeostasis of amylin, a satiety hormone that forms pancreatic amyloid in patients with T2D, promotes accumulation of amylin in cerebral small blood vessels and interaction with Alzheimer's disease (AD) pathology. Overexpression of human amylin in rodents (rodent amylin does not form amyloid) leads to late-life onset T2D and neurologic deficits. In this Review, we discuss clinical evidence of amylin pathology in CVD and AD and identify critical …

Ossification Of The Posterior Longitudinal Ligament: Surgical Approaches And Associated Complications., Jeffery Head, George Rymarczuk, Geoffrey Stricsek, Lohit Velagapudi, Christopher Maulucci, Christian Hoelscher, Md, James Harrop

Department of Neurosurgery Faculty Papers

Ossification of the posterior longitudinal ligament (OPLL) is a rare but potentially devastating cause of degenerative cervical myelopathy (DCM). Decompressive surgery is the standard of care for OPLL and can be achieved through anterior, posterior, or combined approaches to the cervical spine. Surgical correction of OPLL via any approach is associated with higher rates of complications and the presence of OPLL is considered a significant risk factor for perioperative complications in DCM surgeries. Potential complications include dural tear (DT) and subsequent cerebrospinal fluid leak, C5 palsy, hematoma, hardware failure, surgical site infections, and other neurological deficits. Anterior approaches are technically …

Modeling Interval Timing By Recurrent Neural Nets, Theodore Raphan, Eugene Dorokhin, Andrew R. Delamater Aug 2019

Modeling Interval Timing By Recurrent Neural Nets, Theodore Raphan, Eugene Dorokhin, Andrew R. Delamater

Publications and Research

The purpose of this study was to take a new approach in showing how the central nervous system might encode time at the supra-second level using recurrent neural nets (RNNs). This approach utilizes units with a delayed feedback, whose feedback weight determines the temporal properties of specific neurons in the network architecture. When these feedback neurons are coupled, they form a multilayered dynamical system that can be used to model temporal responses to steps of input in multidimensional systems. The timing network was implemented using separate recurrent “Go” and “NoGo” neural processing units to process an individual stimulus indicating the …
