Miao, Sara Thalheimer, Joshua Pelta-Heller, Feroze Mohamed, Ashwini Sharan, James Harrop, Laura Krisa, M. Alizadeh

Farber Institute for Neuroscience Faculty Papers

The great majority of spinal cord injury (SCI) patients have debilitating chronic pain. Despite decades of research, these pain pathways of neuropathic pain (NP) are unknown. SCI patients have been shown to have abnormal brain pain pathways. We hypothesize that SCI NP patients’ pain matrix is altered compared to SCI patients without NP. This study examines the functional connectivity (FC) in SCI patients with moderate-severe chronic NP compared to SCI patients with mild-no NP. These groups were compared to control subjects. The Neuropathic Pain Questionnaire and neurological evaluation based on the International Standard Neurological Classification of SCI were utilized to …

Archives of Neurosurgery

INTRODUCTION: Coccydynia is the condition of disabling pain in the coccyx that occurs when sitting or moving to a standing position. Due to a lack of knowledge by spine specialists, many patients suffer for years without adequate treatment. We highlight the relevance of diagnosing and treating coccygodynia correctly to avoid lumbosacral pathology overestimation. METHODS: We present a series of patients with painful coccygeal segment syndrome associated with different lumbar alterations who underwent coccygectomy from 1996 to 2021 in our spine clinic. We describe VAS and MacNab scores and complication rates. We used Student-T-Test for statistical analysis. RESULTS: We included 40 …

Utilizing Ai Integrated Neuroimaging Technology To Expand Upon Machine Learning In Positron Emission Tomography Technology With The Aim Of Detecting Amyloid Beta Biomarkers Early In The Onset Of Alzheimer's., Ethan S. Terman

Undergraduate Research Posters

Early intervention in Alzheimer's is vital for treatment. The earlier a professional can detect symptoms and make a diagnosis the earlier a prognosis can be implemented. With the prevalence of data in our day-to-day world combined with Artificial intelligence (AI), utilizing both for machine learning can pave the way for more accurate and efficient detection of Alzheimer's and other neurodegenerative diseases. AI combined with Machine learning (ML) increases diagnostic efficiency and reduces human errors, making it a valuable resource for physicians and clinicians alike. With the increasing amount of data processing and image interpretation required, the ability to use AI …

When Divergent Worlds Collide: Dr. Santiago Ramón Y Cajal’S Influence On The Surrealism Movement, William J. Hardman Iii, Md

MA Theses

Dr. Santiago Ramón y Cajal’s drawings were created for the sole purpose of illustrating his newly discovered and earth-shattering revelations in the field of neuroscience culminating with his magnum opus: the “Neuron theory” and the “Theory of Dynamic Polarization.” For these discoveries and many others, he shared the 1906 Nobel Prize in medicine and physiology with his rival Dr. Camilo Golgi, an Italian pathologist. At no time did he envision that his drawings would capture the interest of artists as it did with members of the Surrealism Movement. This thesis will explore and present for the first time supporting evidence …

End Of Life In The Ed – Brain Death And Organ Transplantation, Madison Cohen, Donald Penney

The Journal of Integrated Primary Care

Every year thousands of Americans die awaiting an organ transplant. While our knowledge and experience with organ transplantation has only improved, organ availability continues to be a major issue due to a lack of suitable donor organs. A large population of organ donors are those who have been clinically diagnosed as brain dead. Brain death is defined as the irreversible loss of all brain and brainstem functions. Despite brainstem functions being lost, mechanical ventilation and perfusion techniques allow for proper organ maintenance. This gives brain-dead individuals a unique opportunity to serve as multiple organ donors. However, due to mistrust of …

Clinical Factors Associated With Need For Neurosurgical Care In Young Children With Imaging For Macrocephaly: A Case Control Study, Jessica F. Rohde, Jeffrey Campbell, Julie Barbera, Elena Taylor, Ashok Ramachandra, Christopher Gegg, Andrea Scherer, Joseph Piatt

Department of Pediatrics Faculty Papers

BACKGROUND: Macrocephaly is present in 2.3% of children with important neurosurgical conditions in the differential diagnosis. The objective of this study was to identify clinical associations with actionable imaging findings among children with head imaging for macrocephaly.

METHODS: We conducted a case-control study of head imaging studies ordered for macrocephaly among children 24 months and younger in a multistate children's health system. Four neurosurgeons reviewed the images, determining cases to be a 'concern' if neurosurgical follow-up or intervention was indicated. Electronic health records were reviewed to collect patient-level data and to determine if surgery was performed. Controls were matched 3:1 …

Informed Consent In Surgical Practice With Patients’ Experiences: A Cross-Sectional Study, Seda Kumru, Pakize Yiğit, Meryem Demirtaş, Hüseyin Fındık

Patient Experience Journal

This study aims to evaluate patients' experiences and perspectives regarding informed consent in surgical practice. Data for this cross-sectional study were collected from 276 patients using a questionnaire developed by Falagas et al. Descriptive statistics were employed for all questions. Statistical tests such as the Mann-Whitney U test, Kruskal-Wallis test, and Spearman's rank correlation analysis were performed, and Cohen's effect sizes were reported. IBM SPSS 23.0 was used for all analyses, and p<0.05 was considered statistically significant. A high score on both The Delivered Information Index and The Patient-Physician Index represents a positive informed consent process. Among the participants, 65.2% indicated that they understood all parts of the consent form. Of all patients, 92.8% reported that information about the specific surgical procedure was provided by physicians. However, 47.5% of the patients reported that they did not feel comfortable with their surgeons. The mean score of the Delivered Information Index was 5.63 (2.38). The mean patient-physician relationship score was 14.38 (3.31). There was a moderate positive correlation between the delivered information index and the patient-physician relationship (r=0.50; p<0.001). In addition, there was a moderate positive correlation between the delivered information index and the time spent on the informed consent process, as well as between the patient-physician relationship and the time spent on the informed consent process (r=0.52; r=0.40, respectively). The study emphasized the lack of communication between patients and physicians, the limitation of information on treatment risks, adverse effects, and alternative treatment options.

Phenytoin-Induced Cerebellar Atrophy: A Case For Reversibility Of Neurological Decline, Edwin Mogere, Davis Cheruiyot, Manakhe Nassiuma

General Surgery, East Africa

This case serves as a reminder of the infrequent, yet consequential occurrence of cerebellar degeneration linked to phenytoin usage. Whilst emphasizes the importance of monitoring patients on long-term phenytoin therapy, and it further suggests considering employing bedside imaging tools such as Ultrasound fusion imaging for follow-up of patients at risk of this type of disorder. We present a case study involving a 23-year-old woman who experienced significant neurological impairment resulting in severe cerebellar atrophy while undergoing phenytoin treatment. On cessation of phenytoin, the patient exhibited improvement with enhanced cerebellar function.

A Case Report Of A Primary Cerebral Abscess Due To Nocardia Asteroides In An Immunocompetent Patient, Ileana Elita Mendez, Nicole Marie Barreto, Alan Lanurias, Luis Alberto Rosas

Research Symposium

Background: Brain abscesses caused by Nocardia are rarely reported and have high mortality. It usually affects patients who are immunocompromised and initiates as a lung infection that disseminates hematogenously, though it can also affect those immunocompetent. Cerebral nocardiosis imitates brain tumors, which can delay the initiation of the appropriate antibiotic therapy.

Case Description: We present a case of a 64-year-old immunocompetent male with multiple cerebral abscesses who presented with headaches, left-sided weakness, and ataxia. Upon imaging, multiple brain lesions were revealed. The patient underwent craniotomy and drainage of the mass. He was initially empirically treated, though cultures later grew Nocardia …

About Dying And Death: Thanatology's Place In Medical Curriculum, Jill Dombroski

Electronic Thesis and Dissertation Repository

This study explored how healthcare providers engage in advance care planning and end-of-life care conversations. The research explored what shapes their understanding and the extent to which concepts from thanatology they intuitively bring in, explicitly bring in, and maybe fail to recognize. To achieve this, constructivist grounded theory (CGT) methodology guided the design, data collection, analysis, and interpretation of the findings, which allowed for iteration across interviews and analysis with existing theories and data in the literature. The CGT design encouraged further engagement with the literature in an ongoing iterative fashion as well as with the analysis of the data. …
