Intermediate-Term Risk Of Stroke Following Cardiac Procedures In A Nationally Representative Data Set., Laura Stein, Alison Thaler, John W. Liang, Stanley Tuhrim, Amit S. Dhamoon, Mandip S. Dhamoon

Department of Neurology Faculty Papers

BACKGROUND: Studies on stroke risk following cardiac procedures addressed only perioperative and long-term risk following limited higher-risk procedures, were poorly generalizable, and often failed to stratify by stroke type. We calculated stroke risk in the intermediate risk period following cardiac procedures compared with common noncardiac surgeries and medical admissions.

METHODS AND RESULTS: The Nationwide Readmissions Database contains readmission data for 49% of US admissions in 2013. We compared age-adjusted stroke readmission rates up to 90 days postdischarge. We used Cox regression to calculate hazard ratios, up to 1 year, of stroke risk comparing transcatheter aortic valve replacement versus surgical aortic …

X-Linked Hypomyelination With Spondylometaphyseal Dysplasia (H-Smd) Associated With Mutations In Aifm1., Noriko Miyake, Nicole I Wolf, Ferdy K Cayami, Joanna Crawford, Annette Bley, Dorothy Bulas, Ryan J Taft, Adeline Vanderver, +Several Additional Authors

Neurology Faculty Publications

An X-linked condition characterized by the combination of hypomyelinating leukodystrophy and spondylometaphyseal dysplasia (H-SMD) has been observed in only four families, with linkage to Xq25-27, and recent genetic characterization in two families with a common AIFM1 mutation. In our study, 12 patients (6 families) with H-SMD were identified and underwent comprehensive assessment accompanied by whole-exome sequencing (WES). Pedigree analysis in all families was consistent with X-linked recessive inheritance. Presentation typically occurred between 12 and 36 months. In addition to the two disease-defining features of spondylometaphyseal dysplasia and hypomyelination on MRI, common clinical signs and symptoms included motor deterioration, spasticity, tremor, …

Survival Benefit Of Surgery In Recurrent Glioblastoma Multiforme, Usama Khalid Choudry, Saad Akhtar Khan, Muhammad Shahzad Shamim

Section of Neurosurgery

There is an ongoing debate regarding role of surgery for recurrent glioblastoma multiforme (GBM). Older literature hinted at only modest survival benefits with surgery and a high rate of morbidity. However, more recent literature suggests better survival that may be attributed to better surgical techniques and better options in adjuvant treatment. Herein the authors review recent literature with regards to the possible role of surgery in recurrent GBM and also look into the key factors impacting second surgery.

INTRODUCTION: There may be biologically relevant heterogeneity within typical late-onset Alzheimer's dementia.

METHODS: We analyzed cognitive data from people with incident late-onset Alzheimer's dementia from a prospective cohort study. We determined individual averages across memory, visuospatial functioning, language, and executive functioning. We identified domains with substantial impairments relative to that average. We compared demographic, neuropathology, and genetic findings across groups defined by relative impairments.

RESULTS: During 32,286 person-years of follow-up, 869 people developed Alzheimer's dementia. There were 393 (48%) with no domain with substantial relative impairments. Some participants had isolated relative impairments in memory (148, 18%), visuospatial functioning (117, 14%), …

Depression In Stroke Patients; A Cross Sectional Study Highlighting The Association Of Stroke On Age And Gender Basis., Saira Abbas, Naila Naeem Shahbaz, Muhammad Amir Umer, Sumera Rafat Umer, Asfia Irfan, Adnan Anwar

Pakistan Journal of Neurological Sciences (PJNS)

Stroke is the second leading cause of death. Depressive disorder is characterized by period of sad mood and anhedonia occurring for two consecutive weeks. Among stroke survivors, the consequence of physical and psychological changes can be devastating. One of those psychological changes is post-stroke depression (PSD). Stroke itself has debilitating morbidity and superimposed PSD further decreases the quality of life of patients and impairs recovery. This study leads us to know the magnitude of post stroke depression.

Epidemiological Data Of Neurological Disorders In Pakistan And Neighboring Countries: A Review, Ghulam Hussain, Azhar Rasul, Haseeb Anwar, Muhammad Umar Sohail, Syed Kashif Shahid Kamran, Shahid Mahmood Baig, Asghar Shabbir, Javed Iqbal

Pakistan Journal of Neurological Sciences (PJNS)

Neurological disorders are the impairments of nervous system and are an important and growing cause of morbidity, mortality, and disability. In addition to health costs, those suffering from these conditions are also frequently victimized of stigmatization and discrimination. Stigmatization further minimizes the patients' access to treatment and social activities. These disorders, therefore, require special attention particularly in developing countries where unfortunately, the burden of these disorders remains largely unrecognized. Moreover, the burden imposed by such chronic neurological conditions in general can be expected to be particularly devastating in poor populations. These conditions are emerging as severe public health concerns in …

5th National Headache Update, Abdul Malik

Pakistan Journal of Neurological Sciences (PJNS)

Headache is one of the most common disorders worldwide. On the World Health Organization's ranking of causes of disability, this would bring headache disorders into the 10 most disabling conditions for both genders, and into the five most disabling for women. The prevalence of headache disorders in Pakistan is high, and would be at least on par with that reported in other parts of the world, although a recent epidemiological survey suggests that the prevalence of migraines could be as high as 22%, almost twice that noted in the international literature. Over the years, the Pakistan Headache Society (PHS) has …

Convergent parallel mixed methods triangulation design comprised a cross-sectional survey (n = 81) and 8 focus group discussions with 7-10 poststroke participants in each group. We assessed participant characteristics and obtained insights into their salt consumption attitudes, perceptions, and knowledge. Qualitative responses were analyzed using an inductive approach with thematic analytic procedures. Relationships …

Plekhg5-Regulated Autophagy Of Synaptic Vesicles Reveals A Pathogenic Mechanism In Motoneuron Disease., Patrick Lüningschrör, Beyenech Binotti, Benjamin Dombert, Peter Heimann, Angel Perez-Lara, Carsten Slotta, Nadine Thau-Habermann, Cora R. Von Collenberg, Franziska Karl, Markus Damme, Arie Horowitz, Isabelle Maystadt, Annette Füchtbauer, Ernst-Martin Füchtbauer, Sibylle Jablonka, Robert Blum, Nurcan Üçeyler, Susanne Petri, Barbara Kaltschmidt, Reinhard Jahn, Christian Kaltschmidt, Michael Sendtner

Department of Medicine Faculty Papers

Autophagy-mediated degradation of synaptic components maintains synaptic homeostasis but also constitutes a mechanism of neurodegeneration. It is unclear how autophagy of synaptic vesicles and components of presynaptic active zones is regulated. Here, we show that Pleckstrin homology containing family member 5 (Plekhg5) modulates autophagy of synaptic vesicles in axon terminals of motoneurons via its function as a guanine exchange factor for Rab26, a small GTPase that specifically directs synaptic vesicles to preautophagosomal structures. Plekhg5 gene inactivation in mice results in a late-onset motoneuron disease, characterized by degeneration of axon terminals. Plekhg5-depleted cultured motoneurons show defective axon growth and impaired autophagy …

New Oral Anticoagulants (Noacs) For Cerebral Venous Thrombosis, Maria Khan, Mohammad Wasay

Pakistan Journal of Neurological Sciences (PJNS)

Cerebral venous thrombosis (CVT) is a relatively rare condition that results from thrombosis of the superficial or deep venous sinuses of the brain. The first ever reported case of the condition was back in 1825 and this was diagnosed at autopsy. It took more than 150 years before imaging modalities were developed that could diagnose cases earlier. With the advent of CT and MR venogram, the diagnosis has become much easier and is contributing to a larger number of cases being picked up. Despite that the incidence in Western literature stays low at 1.3-1.6 cases per 100,000 people. Middle Eastern …
