Object. Concussive head injuries have received much attention in the medical and public arenas, as concerns have been raised about the potential shortand long-term consequences of injuries sustained in sports and other activities. While many student athletes have required evaluation after concussion, the exact definition of concussion has varied among disciplines and over time. The authors used data gathered as part of a multiinstitutional longitudinal study of the biomechanics of head impacts in helmeted collegiate athletes to characterize what signs, symptoms, and clinical histories were used to designate players as having sustained concussions.

Methods. Players on 3 college …

Metabolic Syndrome And Migraine., Amit Sachdev, Michael J Marmura

Department of Jefferson Headache Center Papers and Presentations

Migraine and metabolic syndrome are highly prevalent and costly conditions. The two conditions coexist, but it is unclear what relationship may exist between the two processes. Metabolic syndrome involves a number of findings, including insulin resistance, systemic hypertension, obesity, a proinflammatory state, and a prothrombotic state. Only one study addresses migraine in metabolic syndrome, finding significant differences in the presentation of metabolic syndrome in migraineurs. However, controversy exists regarding the contribution of each individual risk factor to migraine pathogenesis and prevalence. It is unclear what treatment implications, if any, exist as a result of the concomitant diagnosis of migraine and …

Risk Factors Associated With Death In In-Hospital Pediatric Convulsive Status Epilepticus, Tobias Loddenkemper, Tanvir U. Syed, Sriram Ramgopal, Deepak Gulati, Sikawat Thanaviratananich, Sanjeev V. Kothare, Amer Alshekhlee, Mohamad Z. Koubeissi

Neurology Faculty Publications

Objective

To evaluate in-patient mortality and predictors of death associated with convulsive status epilepticus (SE) in a large, multi-center, pediatric cohort.

Patients and Methods

We identified our cohort from the KID Inpatient Database for the years 1997, 2000, 2003 and 2006. We queried the database for convulsive SE, associated diagnoses, and for inpatient death. Univariate logistic testing was used to screen for potential risk factors. These risk factors were then entered into a stepwise backwards conditional multivariable logistic regression procedure. P-values less than 0.05 were taken as significant.

Results

We identified 12,365 (5,541 female) patients with convulsive SE aged …

Validation Of A Novel, Non-Invasive System For Autonomic Profiling In Healthy Volunteers, Agostino Ingraldi, Behzad B. Pavri, Himanshu Patel, Sammy Zakaria, Reginald T. Ho, Arnold J. Greenspon

The Medicine Forum

Noninvasive profiling of the autonomic nervous system has been shown to have prognostic value in patients with myocardial infarction, CHF and diabetes. The ANSAR system (ANX 3.0, Philadelphia, PA) is a new commercially available system that utilizes respiratory rate, HR and BP to assess on-going sympathovagal modulation during various maneuvers known to evoke autonomic perturbations. Instead of using conventional Fast Fourier Transform for frequency domain analysis, a Continuous Wavelet Transform (CWT) is used to generate numerical and graphical data. The system calculates Low Frequency Area (LFA, analogous to LF Power) and Respiratory Frequency Area (RFA, analogous to High Frequency Power.) …

A Case Of Invasive Thymoma, Jon Geddes

The Medicine Forum

A 52 year-old man with a past medical history of an isolated seizure presented to the Veterans Affairs hospital complaining of weakness which was most prominent in the face and upper extremities. About 6 months prior to this admission he developed intermittent episodes of weakness when chewing and swallowing. He would often have to use his hands to close his jaw when eating or talking. He noticed that his voice had developed a nasal quality but he did not have slurred speech. He denied drooling, ptosis, cramping or muscle twitches. He was seen 6 months ago at another VA hospital …

Neurophysiological Impact And Modeling-Independent Elucidation Of Inactivation Pathways In A-Type K+ Channels, J.D. Fineberg, David Ritter, Manuel Covarrubias

Department of Molecular Physiology and Biophysics Faculty Papers

Poster presented at Society for Neuroscience

Abstract:

A-type voltage-gated K⁺ channels auto-regulate their function by undergoing fast inactivation. Independent of molecular mechanisms, this inactivation can proceed after channel opening (open-state inactivation, OSI) or from a closed state prior to opening (closed-state inactivation, CSI). We hypothesize that the specific neurophysiological roles of A-type Kv channels depend on whether they undergo OSI, CSI or both (CSI+OSI). To explore these possibilities, we introduced Markov kinetic schemes of the A-type Kv4 conductance into a computational model of the hippocamcal CA1 neuron assuming either CSI or CSI+OSI and compared the properties of the somatic …

Pulmonary Complications In Patients With Severe Brain Injury., Kiwon Lee, Fred Rincon

Department of Neurology Faculty Papers

Pulmonary complications are prevalent in the critically ill neurological population. Respiratory failure, pneumonia, acute lung injury and the acute respiratory distress syndrome (ALI/ARDS), pulmonary edema, pulmonary contusions and pneumo/hemothorax, and pulmonary embolism are frequently encountered in the setting of severe brain injury. Direct brain injury, depressed level of consciousness and inability to protect the airway, disruption of natural defense barriers, decreased mobility, and secondary neurological insults inherent to severe brain injury are the main cause of pulmonary complications in critically ill neurological patients. Prevention strategies and current and future therapies need to be implemented to avoid and treat the development …

Neurosteroid-Mediated Regulation Of Brain Innate Immunity In Hiv/Aids: Dhea-S Suppresses Neurovirulence, Amber Paul, Ferdinand G. Maingat, Maria J. Polyak, Pornpun Vivithanaporn, Farshid Noorbakhsh, Samir Ahboucha, Glen B. Baker, Keir Pearson, Christopher Power

Neurosteroids are cholesterol-derived molecules synthesized within the brain, which exert trophic and protective actions. Infection by human and feline immunodeficiency viruses (HIV and FIV, respectively) causes neuroinflammation and neurodegeneration, leading to neurological deficits. Secretion of neuroinflammatory host and viral factors by glia and infiltrating leukocytes mediates the principal neuropathogenic mechanisms during, although the effect of neurosteroids on these processes is unknown. We investigated the interactions between neurosteroid mediated effects and lentivirus infection outcomes. Analyses of HIV-infected uninfected human brains disclosed a reduction in neurosteroid synthesis enzyme expression. Human neurons exposed to supernatants from HIV macrophages exhibited suppressed enzyme expression without …
