Chronic Inflammatory Demyelinating Polyneuropathy (Cidp) In A Patient With Diabetes: A Primary Care Perspective, Jordan Dever, Adam M. Franks, Laura M. Given, William Rollyson, Adrienne Mays-Kingston

Marshall Journal of Medicine

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a recurrent and progressive disease that causes proximal, symmetrical extremity weakness. The disease is diagnosed using clinical features, electrophysiologic testing, albumino-cytological disassociation in the cerebrospinal fluid, and sural nerve plexus biopsy. However, because of the low sensitivity of diagnostic criteria and other similar neuropathies, including diabetic polyneuropathy (DPN), accurate diagnosis is difficult. Differentiating between these diseases is especially important as CIDP’s changes are reversible and DPN’s are not. Making this differentiation allows for symptomatic improvement in a patient’s quality of life that would not be achieved otherwise. Early recognition and treatment, with modalities including …

Anesthetic Use In Status Epilepticus: A Concise Review, Furkan M. Yilmaz, Lauren A. Igneri, Yasir A. Yilmaz, Evren Burakgazi-Dalkilic

Cooper Rowan Medical Journal

The purpose of this review is to summarize the recent literature focusing on intravenous (IV) administration of commonly used anesthetics, including midazolam, pentobarbital/ thiopental, propofol, and ketamine in the treatment of status epilepticus (SE). Anesthetics should be reserved as third-line therapy for the treatment of SE when benzodiazepines and other second-line agents fail to terminate the seizure. We have reviewed the literature related to the treatment of status epilepticus, refractory status epilepticus, super-refractory status epilepticus, anesthetics, midazolam, pentobarbital/thiopental, propofol, and ketamine. This paper focuses on the pharmacology, dosages, major side effects, and clinical use of IV anesthetics in the treatment …

Physical Therapy Faculty Articles and Research

Background

Studies examining the effects of therapeutic interventions after stroke often focus on changes in loss of body function/structure (impairment). However, improvements in activities limitations and participation restriction are often higher patient priorities, and the relationship that these measures have with loss of body function/structure is unclear.

Objective

This study measured gains across WHO International Classification of Function (ICF) dimensions and examined their interrelationships.

Methods

Subjects were recruited 11 to 26 weeks after hemiparetic stroke. Over a 3-week period, subjects received 12 sessions of intensive robot-based therapy targeting the distal arm. Each subject was assessed at baseline and at 1 …

Consequences Of A Missed History: A Case Of Antidepressant Discontinuation Syndrome, Sajid Hameed, Mukesh Kumar, Piyush Puri, Fnu Sapna, Pal Satyajit Singh Athwal

Section of Neurology

Antidepressant discontinuation syndrome (ADDS) is reported to occur in almost 30-50% of the patients who take antidepressants for a duration of at least four to six weeks and then suddenly discontinue the drug. Since there is an increase in the use of antidepressants for various reasons by general practitioners, patient education about when and how to discontinue a drug is not acknowledged enough. It is reported to occur with the use of different classes of antidepressants - selective serotonin reuptake inhibitor (SSRI), monoamineoxidase inhibitor (MAOI), tricyclic antidepressants (TCAs), and atypical antipsychotics like risperidone, trazodone, clozapine, and venlafaxine. Slow tapering off …

Effect Of Bout Length On Gait Measures In People With And Without Parkinson’S Disease During Daily Life, Vrutangkumar Shah, James Mcnames, Graham Harker, Martina Mancini, Patricia Carlson-Kuhta, John G. Nutt, Mahmoud El-Gohary, Carolin Curtze, Fay Horak

Electrical and Computer Engineering Faculty Publications and Presentations

Although the use of wearable technology to characterize gait disorders in daily life is increasing, there is no consensus on which specific gait bout length should be used to characterize gait. Clinical trialists using daily life gait quality as study outcomes need to understand how gait bout length affects the sensitivity and specificity of measures to discriminate pathological gait as well as the reliability of gait measures across gait bout lengths. We investigated whether Parkinson’s disease (PD) affects how gait characteristics change as bout length changes, and how gait bout length affects the reliability and discriminative ability of gait measures …

Plasma Proteins That May Cause Parkinson’S Disease And Multiple Sclerosis: A Mendelian Randomization Study, Brigid A. Staley

Dissertations and Theses

Multiple sclerosis (MS) and Parkinson’s disease (PD) are progressively disabling neurologic disorders that profoundly affect quality of life and shorten life expectancy. There is no cure for either disease, and current treatments only alleviate symptoms and may cause serious side effects. The causes of MS and PD are not well understood. Previous epidemiologic studies have documented numerous environmental risk factors for both diseases. However, these studies are inherently prone to bias from confounding which may generate spurious results. The lack of unbiased evidence on environmental causes of MS and PD has been a critical barrier to fully understanding their pathophysiology. …

Acute And Chronic Dosing Of A High-Affinity Rat/Mouse Chimeric Transferrin Receptor Antibody In Mice, Demi M. Castellanos, Jiahong Sun, Joshua Yang, Weijun Ou, Alexander C. Zambon, William M. Pardridge, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Non-invasive brain delivery of neurotherapeutics is challenging due to the blood-brain barrier. The revived interest in transferrin receptor antibodies (TfRMAbs) as brain drug-delivery vectors has revealed the effect of dosing regimen, valency, and affinity on brain uptake, TfR expression, and Fc-effector function side effects. These studies have primarily used monovalent TfRMAbs with a human constant region following acute intravenous dosing in mice. The effects of a high-affinity bivalent TfRMAb with a murine constant region, without a fusion partner, following extravascular dosing in mice are, however, not well characterized. Here we elucidate the plasma pharmacokinetics and safety of a high-affinity bivalent …

Comparison Of Machine Learning Models: Gesture Recognition Using A Multimodal Wrist Orthosis For Tetraplegics, Charlie Martin

The Journal of Purdue Undergraduate Research

Many tetraplegics must wear wrist braces to support paralyzed wrists and hands. However, current wrist orthoses have limited functionality to assist a person’s ability to perform typical activities of daily living other than a small pocket to hold utensils. To enhance the functionality of wrist orthoses, gesture recognition technology can be applied to control mechatronic tools attached to a novel fabricated wrist brace. Gesture recognition is a growing technology for providing touchless human-computer interaction that can be particularly useful for tetraplegics with limited upper-extremity mobility. In this study, three gesture recognition models were compared—two dynamic time-warping models and a hidden …

Occupational Therapy’S Role In Addressing Sex And Intimacy For Individuals With Progressive Neuromuscular Disorders, Lindsay N. Richards, Becki Cohill, Katrhyn Ellis, Susan Macdermott

San Marcos, Summer 2020

Individuals with progressive neuromuscular disorders (PND); specifically, Parkinson’s disease (PD), Multiple Sclerosis (MS), Huntington’s Disease (HD), and Amyotrophic Lateral Sclerosis (ALS) often face physical, psychological, and social challenges related to sex and intimacy. Occupational therapy (OT) practitioners are experts in activity analysis and are equipped with unique knowledge of performance skills and client factors to address deficits in occupational performance.

Though there is literature presenting the effects of PND on sexual occupations, a gap exists as it relates to qualitative data from the perspective of the individual and their partners. A mixed-methods survey was conducted examining the lived experience of …

Department of Paediatrics and Child Health

Objectives: Considering the dearth of literature on West syndrome (WS) from South Asian countries, this study aimed to evaluate the management practices in South Asia by an online survey and meta-analysis.
Methods: An online questionnaire was sent to 223 pediatric neurologists/pediatricians in India, Pakistan, Myanmar, Sri Lanka, Bhutan, Nepal, and Bangladesh. Their responses were evaluated and supplemented by a meta-analysis.
Results: Of 125 responses received (response rate: 56%), around 60% of responders observed male preponderance and an approximate lead-time-to-treatment (LTTT) of 4-12 weeks. The commonest etiology observed was a static structural insult (88.6% of responders). Most commonly used first-line drug …

Effect Of S100b Deletion On Membrane Properties And Localization Of Ncald And Hpca, Natasha Hesketh

Graduate School of Biomedical Sciences Theses and Dissertations

Calcium signaling is particularly important for neuronal function. Neurons utilize a wide range of calcium-binding proteins. Dysregulation of such proteins is linked to neurodegeneration. Neurocalcin delta (NCALD), hippocalcin (HPCA), and S100B are calcium sensors that are expressed in the hippocampus, a brain region essential to memory and severely damaged in Alzheimer’s disease (AD). Despite the potential importance of these proteins, we do not fully understand the physiological significance of their relationship. Because NCALD and HPCA are known to interact with S100B, we hypothesized that the loss of S100B affects NCALD and HPCA localization, and therefore electrical properties, of hippocampal neurons. …

A Fatal Case Of Primary Amoebic Meningoencephalitis (Pam) Complicated With Diabetes Insipidus (Di): A Case Report And Review Of The Literature, Zain Mushtaq, Saad Bin Zafar Mahmood, Adil Aziz

Section of Internal Medicine

Naegleria fowleri is a highly infective free-living amoeba usually isolated from soil and fresh water and is primarily found to infect the central nervous system (CNS) resulting in primary amoebic meningoencephalitis (PAM). PAM as a cause of meningitis is often overlooked for other, more common causes of meningitis. Despite all the advances in antimicrobial therapy and supportive care systems, the mortality rate of this rare infection remains above 95% with the bulk of the cases being found in developed countries. We are presenting a case of a 44-year-old male with fever, worsening headache, and generalized weakness. Lumbar puncture showed a …

Free L-Glutamate-Induced Modulation In Oxidative And Neurochemical Profile Contributes To Enhancement In Locomotor And Memory Performance In Male Rats, Saiqa Tabassum, Saara Ahmad, Syeda Madiha, Sidrah Shahzad, Zehra Batool, Sadia Sadir, Saida Haider

Department of Biological & Biomedical Sciences

Glutamate (Glu), the key excitatory neurotransmitter in the central nervous system, is considered essential for brain functioning and has a vital role in learning and memory formation. Earlier it was considered as a harmful agent but later found to be useful for many body functions. However, studies regarding the effects of free L-Glu administration on CNS function are limited. Therefore, current experiment is aimed to monitor the neurobiological effects of free L-Glu in male rats. L-Glu was orally administered to rats for 5-weeks and changes in behavioral performance were monitored. Thereafter, brain and hippocampus were collected for oxidative and neurochemical …

Using A Timed Motor Task To Predict One-Year Functional Decline In Amnestic Mild Cognitive Impairment, Sydney Y. Schaefer, Andrew Hooyman, Kevin Duff

Physical Therapy Faculty Articles and Research

Affordable, noninvasive methods of predicting functional decline are needed for individuals at risk for Alzheimer’s disease. This study tested whether a timed upper-extremity motor task predicted functional decline over one year in 79 adults diagnosed with amnestic mild cognitive impairment. Participants completed subjective and objective measures of daily functioning at baseline and one year later. Motor task performance and delayed memory were also evaluated at baseline. Motor task performance was a significant predictor of one-year follow-up daily functioning, improving model fits by 18– 35%. Thus, motor behavior has potential to be an affordable enrichment strategy that is sensitive to functional …
