Acute Stroke Secondary To Internal Carotid Artery Pseudoaneurysm: Mri Findingsand Treatment With Endovascularcoiling, Mohammad Wasay, Alper Dai, Neeraj Dubey, Saadat Kamran Jul 2007

Acute Stroke Secondary To Internal Carotid Artery Pseudoaneurysm: Mri Findingsand Treatment With Endovascularcoiling, Mohammad Wasay, Alper Dai, Neeraj Dubey, Saadat Kamran

Department of Medicine

Internal carotid artery pseudoaneurysms are uncommon. We report a young man with history of trivialtrauma who presented with middle cerebral artery stroke.Head CT scan revealed a right parapharyngeal mass. MRI confirmed the diagnosis of internal carotidpseudoaneurysm. Cerebral angiogram showed dissection of internal carotid artery with a large pseudoaneurysm and almost complete occlusion of vessel distal to aneurysm.Vessel was obliterated by fibercoiling and gluing byendovascular technique to diminish risk of furthere mbolization. MRI characteristics of carotid pseudoaneurysms and role of endovascular treatment arediscussed.

Department of Neurology Faculty Papers

Light, including artificial light, has a range of effects on human physiology and behavior and can therefore alter human physiology when inappropriately timed. One example of potential light-induced disruption is the effect of light on circadian organization, including the production of several hormone rhythms. Changes in light-dark exposure (e.g., by nonday occupation or transmeridian travel) shift the timing of the circadian system such that internal rhythms can become desynchronized from both the external environment and internally with each other, impairing our ability to sleep and wake at the appropriate times and compromising physiologic and metabolic processes. Light can also have …

Caring For People With Alzheimer's Disease Or Dementia In Maine, Stuart Bratesman Mpp, Julie T. Fralich Mba, Catherine Mcguire Bs, Louise Olsen, Romaine Turyn Mar 2007

Caring For People With Alzheimer's Disease Or Dementia In Maine, Stuart Bratesman Mpp, Julie T. Fralich Mba, Catherine Mcguire Bs, Louise Olsen, Romaine Turyn

Disability & Aging

It is clear that caring for people with Alzheimer’s disease and dementia is a growing public health issue. Alzheimer’s is a progressively deteriorating disease that can last anywhere from 1 to 15 years. Families are the primary caregivers and will continue to need support to manage the care of their loved ones, to coordinate services within the long term care system and to maintain their own health and well-being.

Cephalalgiaphobia: A Possible Specific Phobia Of Illness., Mario F P Peres, Juliane P P Mercante, Vera Z Guendler, Felipe Corchs, Marcio A Bernik, Eliova Zukerman, Stephen Silberstein

Department of Jefferson Headache Center Papers and Presentations

Psychiatric comorbidity, mainly anxiety and depression, are common in chronic migraine (CM). Phobias are reported by half of CM patients. Phobic avoidance associated with fear of headache or migraine attack has never been adequately described. We describe 12 migraine patients with particular phobic-avoidant behaviours related to their headache attacks, which we classified as a specific illness phobia, coined as cephalalgiaphobia. All patients were women, mean age 42, and all had a migraine diagnosis (11 CM, all overused acute medications). Patients had either a phobia of a headache attack during a pain-free state or a phobia of pain worsening during mild …

In Pakistan, students who are accepted into medical school are congratulated — only half-jokingly — on three counts: that they will become doctors, that they will become certified by the American Board of Medical Specialties, and that they will soon be living in the United States.


Contrasting Roles Of Neural Firing Rate And Local Field Potentials In Human Memory, A. Ekstrom, Indre Viskontas, M. Kahana, J. Jacobs, K. Upchurch, S. Bookheimer, I. Fried Jan 2007

Contrasting Roles Of Neural Firing Rate And Local Field Potentials In Human Memory, A. Ekstrom, Indre Viskontas, M. Kahana, J. Jacobs, K. Upchurch, S. Bookheimer, I. Fried

Psychology

Recording the activity of neurons is a mainstay of animal memory research, while human recordings are generally limited to the activity of large ensembles of cells. The relationship between ensemble activity and neural firing rate during declarative memory processes, however, remains unclear. We recorded neurons and local field potentials (LFPs) simultaneously from the same sites in the human hippocampus and entorhinal cortex (ERC) in patients with implanted intracranial electrodes during a virtual taxi-driver task that also included a memory retrieval component. Neurons increased their firing rate in response to specific passengers or landmarks both during navigation and retrieval. Although we …

Spectrum Of Intracranial Pathology: Tumors Versus Infections At A Tertiary Care Hospital, Muhib Alam Khan, Sukaina Aijazali Panju, Ather Enam

Section of Neurosurgery

Introduction: Aga Khan University Hospital Neurosurgery Department has evolved into a high-volume centre for treatment of neurosurgical diseases. We aimed to compare the relative outcomes of intracranial tumors and CNS infections seen at our facility.
Methods: Hospital records of patients admitted under the neurosurgery service between 1994-2003 were evaluated. Cases with a principal diagnosis of an intracranial lesion were identified for further study. Demographic, clinical,and surgical variables were extracted from the medical record. Length of hospital stay, ICU utilization, and in-hospital mortality were the primary outcome indicators. Data were analyzed through descriptive statistics and comparisons of meansand proportions. …

Farber Institute for Neuroscience Faculty Papers

ABSTRACT: BACKGROUND: Shedding of the Alzheimer amyloid precursor protein (APP) ectodomain can be accelerated by phorbol esters, compounds that act via protein kinase C (PKC) or through unconventional phorbol-binding proteins such as Munc13-1. We have previously demonstrated that application of phorbol esters or purified PKC potentiates budding of APP-bearing secretory vesicles at the trans-Golgi network (TGN) and toward the plasma membrane where APP becomes a substrate for enzymes responsible for shedding, known collectively as alpha-secretase(s). However, molecular identification of the presumptive "phospho-state-sensitive modulators of ectodomain shedding" (PMES) responsible for regulated shedding has been challenging. Here, we examined the effects on …


Herpes Simplex Virus 1 And Chlamydophila (Chlamydia) Pneumoniae Promote Ab 1-42 Amyloid Processing In Murine Astrocytes Linking An Infectious Process To Alzheimer's Disease, Laura R. Triplett, Adam L. Dore, Kevin S. Kralik, Brian J. Balin, Susan T. Hingley, Denah M. Appelt Jan 2007

Herpes Simplex Virus 1 And Chlamydophila (Chlamydia) Pneumoniae Promote Ab 1-42 Amyloid Processing In Murine Astrocytes Linking An Infectious Process To Alzheimer's Disease, Laura R. Triplett, Adam L. Dore, Kevin S. Kralik, Brian J. Balin, Susan T. Hingley, Denah M. Appelt

Scholarly Posters

Background: Several studies have suggested an infectious etiology for Alzheimer's disease (AD). Previously, our laboratory identified Chlamydia pneumoniae (Cpn) from autopsied sporadic AD brains, as well as developed a BALB/c mouse model that demonstrated infection-induced amyloid plaques similar to those found in AD. Hypothesis: We propose that an additional pathogen such as herpes simplex virus type 1 (HSV1), also may be a contributing factor in toin the pathology seen in AD. HSV1, in addition to Cpn, may be triggering the abnormal cleavage of the beta amyloid precursor protein (bAPP) into Ab1-42 , thereby contributing to amyloid plaque formation. Our current …


A Turner Syndrome Neurocognitive Phenotype Maps To Xp22.3., Andrew R Zinn, David Roeltgen, Gerry Stefanatos, Purita Ramos, Frederick F Elder, Harvey Kushner, Karen Kowal, Judith L Ross Jan 2007

A Turner Syndrome Neurocognitive Phenotype Maps To Xp22.3., Andrew R Zinn, David Roeltgen, Gerry Stefanatos, Purita Ramos, Frederick F Elder, Harvey Kushner, Karen Kowal, Judith L Ross

Department of Pediatrics Faculty Papers

BACKGROUND: Turner syndrome (TS) is associated with a neurocognitive phenotype that includes selective nonverbal deficits, e.g., impaired visual-spatial abilities. We previously reported evidence that this phenotype results from haploinsufficiency of one or more genes on distal Xp. This inference was based on genotype/phenotype comparisons of individual girls and women with partial Xp deletions, with the neurocognitive phenotype considered a dichotomous trait. We sought to confirm our findings in a large cohort (n = 47) of adult women with partial deletions of Xp or Xq, enriched for subjects with distal Xp deletions. METHODS: Subjects were recruited from North American genetics and …
