Background: The large geographical gaps in our knowledge of the prevalence and burden of headache disorders include almost all of Eastern Mediterranean Region (EMR). We report a nationwide population-based study in Pakistan, an EMR country with the sixth largest population in the world, conducted as a project within the Global Campaign against Headache.
Methods: We surveyed six locations from the four provinces of Pakistan: Punjab, Sindh, Khyber Pakhtunkhwa and Baluchistan. We randomly selected and visited rural and urban households in each. One adult member (18–65 years) of each household, also randomly selected, was interviewed by a trained non-medical interviewer ...
Autism- Towards Comprehensive Assessment And Management, 2017 Aga Khan University Hospital Karachi,pakistan
Autism- Towards Comprehensive Assessment And Management, Ayesha Mian
Autism is a pervasive, neurodevelopmental disorder characterized by stereotyped movements and impairment in social skills and communication patterns. Prevalence patterns show an increasing burden of about 1 in 150 children affected by the disorder. Most affected individuals have symptoms that interfere greatly with quality of life. Although a burgeoning concern, research on the prevalence, etiological factors and presentation patterns is limited in LAMI countries, leading to a minimal understanding of the disorder at individual, professional and societal level. There is an urgent need to enhance awareness and education to decrease stigma that maybe associated with autism.

Brain-derived neurotrophic factor (BDNF), a key player in regulating synaptic strength and learning, is dysregulated following traumatic brain injury (TBI), suggesting that stimulation of BDNF signaling pathways may facilitate functional recovery. This study investigates whether CN2097, a peptidomimetic ligand which targets the synaptic scaffold protein, postsynaptic density protein 95, to enhance downstream signaling of tropomyosin-related kinase B, a receptor for BDNF, can improve neurological function after TBI. Moderate to severe TBI elicits neuroinflammation and c-Jun-N-terminal kinase (JNK) activation, which is associated with memory deficits. Here we demonstrate that CN2097 significantly reduces the post-traumatic synthesis of proinflammatory mediators and inhibits the ...

Intracranial Hypertension And Optic Nerve Sheath Fenestration, 2017 Aga Khan University Hospital
Intracranial Hypertension And Optic Nerve Sheath Fenestration, Irfan Jeeva
Intracranial Hypertension is a neurological condition secondary to raised intracranial pressure in the absence of identifiable intracranial pathology and with normal cerebrospinal fluid composition. It can be a challenging condition to manage. One of the treatment modalities, optic nerve sheath fenestration is an important, yet under utilized mode of treatment, particularly in patients with visual symptoms.
The Effects Of Dance Therapy On Patients With Parkinson’S Disease: An Integrative Literature Review, Jennifer Pence
Grace Peterson Nursing Research Colloquium
Parkinson’s disease (PD) is a chronic, progressive, degenerative disease of the nervous system that affects more than one million Americans. Individuals who have PD generally exhibit bradykinesia, postural instability, shuffling steps and freezing during gait. These impairments in motor function cannot be fully addressed with pharmacological treatment and can eventually become unresponsive to this form of treatment. Dance therapy, on the other hand, is one non-pharmacological method that may prove beneficial for PD. It utilizes motor planning skills, which can lead to an improvement in muscle flexibility and balance. The purpose of the systematic integrative literature review was ...
Role Of Surgery In Brain Metastases, 2017 Aga Khan University
Role Of Surgery In Brain Metastases, Altaf Ali Laghari, Syed Ijlal Ahmed, Muhammad Shahzad Shamim

Abstract Brain metastases remain the commonest type of brain tumour, being four times more common than primary brain tumours. Although surgical intervention may be recommended for one of various reasons in the management of these tumours, including but not limited to conformation of diagnosis, relief of mass effect, improvement of neurological status and prolongation of survival, the guidelines for management of brain metastases remain largely subjective and therefore controversial. Herein the authors have attempted to review some of the existing evidence on role of surgery in the management of brain metastases and have presented their selected guidelines for the readers.

Objective: To investigate the genetic etiology of a patient diagnosed with leukoencephalopathy, brain calcifications, and cysts (LCC).
Methods: Whole-exome sequencing was performed on a patient with LCC and his unaffected family members. The variants were subject to in silico and in vitro functional testing to determine pathogenicity.
Results: Whole-exome sequencing uncovered compound heterozygous mutations in EARS2, c.328G>A (p.G110S), and c.1045G>A (p.E349K). This gene has previously been implicated in the autosomal recessive leukoencephalopathy with thalamus and brainstem involvement and high lactate (LTBL). The p.G110S mutation has been found in multiple patients with LTBL. In ...

BACKGROUND: The tumor microenvironment often polarizes infiltrating macrophages towards a type 2, or M2 phenotype, that is characterized by expression of various cysteine-rich, scavenger receptors, including CD163. The primary function of M2 macrophages is to facilitate wound healing. As such, they are capable of providing metabolic support to a growing tumor, neovascularization, as well as protection from cytotoxic T cells. The tumor microenvironment contains a milieu of secreted factors and vesicles, which in certain circumstances can gain access to lymphatic vessels that drain to local lymph nodes.
CASE PRESENTATION: We report a 59-year-old male with recurrent T4 squamous cell carcinoma ...

Objective: Surrogate decision-makers (“surrogates”) and physicians of incapacitated patients have different views of prognosis and how it should be communicated, but this has not been investigated in neurocritically-ill patients. We examined communication preferences in surrogates and physician practices during the outcome prognostication for critically-ill traumatic brain injury (ciTBI) patients in neuroICUs.
Design: Qualitative study using in-person semi-structured interviews with surrogates of ciTBI patients and physicians with expertise in TBI.
Setting: Two neuroICUs at two level-1 trauma centers (surrogates); seven academic U.S. medical centers (physicians).
Subjects: Sixteen surrogates for 15 ciTBI patients and 20 attending physicians from neurocritical care, neurosurgery ...

Introduction: The International Patient Decision Aid Standards, a framework for the creation of high-quality decision aids, calls for the presentation of probabilities. To inform the content of a goals-of-care decision aid in critically-ill TBI (ciTBI) patients, we examined physician’s awareness, perceptions, and use of the IMPACT-model, the most widely validated ciTBI outcome model, and explored their preferences for communicating prognostic information towards families.
Methods: We conducted a qualitative study using semi-structured interviews in 20 attending physicians (neurocritical care, neurosurgery, trauma, palliative care) at 7 U.S. academic medical centers. We used descriptive statistics and performed qualitative content analysis of ...

Alzheimer’s disease (AD) is an irreversible neurodegenerative disease characterized by a progressive decline in cognition and memory, leading to significant impairment in daily activities and ultimately death. It is the most common cause of dementia, the prevalence of which increases with age; however, age is not the only predisposing factor. The pathology of this cognitive impairing disease is still not completely understood, which has limited the development of valid therapeutic options. Recent years have witnessed a wide range of novel approaches to combat this disease, so that they greatly increased our understanding of the disease and of the unique ...

PURPOSE: Thromboembolic complications remain a limitation of flow diverting stents. We hypothesize that phosphorilcholine surface modified flow diverters (Pipeline Flex with Shield Technology, sPED) would have less acute thrombus formation on the device surface compared with the classic Pipeline Embolization device (cPED).
METHODS: Elastase-induced aneurysms were created in 40 rabbits and randomly assigned to receive cPED or sPED devices with and without dual antiplatelet therapy (DAPT) (four groups, n=10/group). Angioplasty was performed to enhance apposition and create intimal injury for a pro-thrombotic environment. Both before and after angioplasty, the flow diverter was imaged with intravascular optical coherence tomography ...

Background: There is very little information about the quality of life (QOL) of stroke survivors in LMIC countries with underdeveloped non communicable health infrastructures, who bear two thirds of the global stroke burden. Methodology: We used a sequential mix methods approach. First, a quantitative analytical cross-sectional study was conducted on 700 participants, who constituted 350 stroke survivor and their caregiver dyads. QOL of stroke survivor was assessed via Stroke Specific Quality of Life Scale (SSQOLS) whereas QOL of caregivers was assessed through RAND-36. In addition; we assessed complications, psychosocial and functional disability of stroke survivors. Following this quantitative survey, caregivers ...

Multinucleate cellular syncytial formation is a hallmark of skeletal muscle differentiation. Myomaker, encoded by Mymk (Tmem8c), is a well-conserved plasma membrane protein required for myoblast fusion to form multinucleated myotubes in mouse, chick, and zebrafish. Here, we report that autosomal recessive mutations in MYMK (OMIM 615345) cause Carey-Fineman-Ziter syndrome in humans (CFZS; OMIM 254940) by reducing but not eliminating MYMK function. We characterize MYMK-CFZS as a congenital myopathy with marked facial weakness and additional clinical and pathologic features that distinguish it from other congenital neuromuscular syndromes. We show that a heterologous cell fusion assay in vitro and allelic complementation ...

Cold atmospheric plasma (CAP), a novel promising anti-cancer modality, has shown its selective anti-cancer capacity on dozens of cancer cell lines in vitro and on subcutaneous xenograft tumors in mice. Over the past five years, the CAP-stimulated solutions (PSS) have also shown their selective anti-cancer effect over different cancers in vitro and in vivo. The solutions used to make PSS include several bio-adaptable solutions, mainly cell culture medium and simple buffered solutions. Both the CAP-stimulated medium (PSM) and the CAP-stimulated buffered solution (PSB) are able to significantly kill cancer cells in vitro. In this study, we systematically compared the anti-cancer ...

Department of Neurology Faculty Papers
Pilot clinical trials of human patients implanted with devices that can chronically record and stimulate ensembles of hundreds to thousands of individual neurons offer the possibility of expanding the substrate of cognition. Parallel trains of firing rate activity can be delivered in real-time to an array of intermediate external modules that in turn can trigger parallel trains of stimulation back into the brain. These modules may be built in software, VLSI firmware, or biological tissue as in vitro culture preparations or in vivo ectopic construct organoids. Arrays of modules can be constructed as early stage whole brain emulators, following canonical ...
