The (R)- Isomer Of Isometheptene Decreases Trigeminal Sensitivity In A Rat Model Of Primary Headache, Jessica Perino, Ms, Nathan T. Fried, Phd, Michael L. Oshinsky, Phd, Bruce Daugherty, Phd, Mba, Seth Lederman, Md, Melanie B Elliott, Phd

Department of Neurosurgery Posters

Introduction

Isometheptene is thought to be the active ingredient of the commonly known headache medication, Midrin. Previously, we found only the (R) enantiomer to be effective in alleviating headache behavior in two models of headache compared to the (S) enantiomer.

Experiments using electrical and mechanical stimulation of the dura in animals with no history of head pain have been used to elucidate the mechanisms of the trigeminovascular system at the level of the trigeminal ganglion, trigeminal nucleus caudalis, periaqueductal gray, and the thalamus. The limitation of these acute models is that electrical and mechanical stimulation of the dural blood vessels …

James Mann, M.D. (1759-1832): Military Surgeon For The "Second War Of Independence"., Eliza C. Anderson, Md, Scott W. Cowan, Md, Charles J. Yeo, Md

Department of Surgery Gibbon Society Historical Profiles

The War of 1812 is remembered for the Burning of Washington, and Francis Scott Key’s “The Star Spangled Banner,” but little else. It was a poorly funded war of relatively short duration and nebulous resolution. Under such circumstances, it is understandable that the “Second War of Independence” failed to produce many notable military or medical advancements. However, one surgeon took it upon himself to recount his experiences in the field. For his dedication to the art and science of medicine, James Mann deserves recognition.

Perforated Sub-Hepatic Appendix; Rare Presentation Of A Common Disease., Huzaifa Ali Jaliawala, Fatima Mannan, Roger Gill, Abdul Rehman Alvi

Department of Surgery Docs

Abstract

An elderly gentleman presented to our emergency with a 10-day history of right upper quadrant pain and nausea with associated tenderness on examination. His white cell counts were raised with predominant neutrophils with ultrasound evidence of a heterogeneous sub-hepatic collection, not associated with fever, diarrhoea or vomiting. He had a similar episode 3 weeks ago, which resolved with antibiotics. Initially thought to be a perforated acute appendicitis or a liver abscess a CT scan was done to further substantiate our finding. This to the contrary revealed a perforated sub hepatic appendix. Patient was treated conservatively with IV fluids and …

Asymptomatic Left Ventricular Myxoma In A 12-Year-Old Male., Meghan Chlebowski, James O'Brien, Casey Hertzenberg, Jonathan B. Wagner

Manuscripts, Articles, Book Chapters and Other Papers

Cardiac myxoma is the most common cardiac tumor in patients of all ages; the majority are encountered as single left atrial tumors. Left ventricular myxomas are exceedingly rare, having been recorded in a small number of case reports involving children worldwide. We report a case of a left ventricular myxoma with left ventricular outflow tract obstruction in a previously healthy, asymptomatic adolescent black male. Transthoracic echocardiograms revealed a single, large (2.5 × 5-cm), lobulated, mobile mass within the left ventricular cavity that oscillated into the outflow tract, thereby causing moderate obstruction during systole. Advanced images delineated the location and tissue …

Section of Neurosurgery

Background: Chronic granulomatous disease (CGD) is an immune disorder that affects phagocytes. It is characterized by recurrent or persistent bacterial and fungal infections. Reports of tuberculosis (TB) in patients with CGD are rare. In developing countries, where TB is endemic, possibility of other chronic infections is often overlooked by physicians.
Case description: We report the case of a 4-year-old boy who had recurrent respiratory infections and episodes of headache. He was put on antituberculosis (ATT) drugs without microbiological or pathological evidence 2 months prior to presentation. The child did not improve and was brought to our hospital where a computed …

Residents’ Perception On The Need For Clinical Leadership Training At The Aga Khan University, Nairobi, Lance Mayabi

Master of Medicine in General Surgery

Background:The healthcare environment is becoming increasingly complex with physicians undertaking more leadership roles. The majority of physicians are not prepared to take up these roles, despite evolving evidence that good clinical leadership yields better clinical outcomes for both patients and healthcare organizations. Further, few residency programs explicitly embed leadership training for their students despite their positions at the forefront of healthcare delivery. This deficit ultimately leaves a multilevel healthcare “leadership” gap in a sector that depends heavily on the education process to improve clinical outcomes. A pre-study survey of residency graduates at the Aga Khan University, Nairobi (AKU,N) undertaken by …

Effect Of Additional Lumbosacral Corset On The Outcome Of Patients With Non-Specific Acute Low Back Pain At The Aga Khan University Hospital, Nairobi, Stanley Aruyaru Mwenda

Master of Medicine in General Surgery

Introduction: Low back pain (LBP) is a common problem world over affecting 60-90% of the population in their lifetime. It is a leading reason for hospital admission, healthcare spending, workplace absenteeism and years lived with disability. Up to 90% of patients suffering from low back pain do not have a serious pathology warranting imaging or further intervention besides symptom relief. These are categorized as having non- specific low back pain. This has a good prognosis running a short course of 3 to 6 weeks. The management of non-specific acute LBP entails analgesia and non-pharmacologic interventions (back school and physical therapy). …

Management Considerations Of Massive Hemoptysis While On Extracorporeal Membrane Oxygenation., Harrsion T. Pitcher, Meredith A. Harrison, Colette Shaw, Scott W. Cowan, Hitoshi Hirose, Nicholas C. Cavarocchi

Department of Surgery Faculty Papers

BACKGROUND: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is a life-saving procedure in patients with both respiratory and cardiac failure. Bleeding complications are common since patients must be maintained on anticoagulation. Massive hemoptysis is a rare complication of ECMO; however, it may result in death if not managed thoughtfully and expeditiously.

METHODS: A retrospective chart review was performed of consecutive ECMO patients from 7/2010-8/2014 to identify episodes of massive hemoptysis. The management of and the outcomes in these patients were studied. Massive hemoptysis was defined as an inability to control bleeding (>300 mL/day) from the endotracheal tube with conventional maneuvers, …

Department of Neurosurgery Faculty Papers

Intraoperative neurophysiological monitoring during endoscopic, endonasal approaches to the skull base is both feasible and safe. Numerous reports have recently emerged from the literature evaluating the efficacy of different neuromonitoring tests during endonasal procedures, making them relatively well-studied. The authors report on a comprehensive, multimodality approach to monitoring the functional integrity of at risk nervous system structures, including the cerebral cortex, brainstem, cranial nerves, corticospinal tract, corticobulbar tract, and the thalamocortical somatosensory system during endonasal surgery of the skull base. The modalities employed include electroencephalography, somatosensory evoked potentials, free-running and electrically triggered electromyography, transcranial electric motor evoked potentials, and auditory …

Section of Neurosurgery

Acute cerebellitis (AC) is a rare inflammatory childhood disorder. Although there is no consensus on standard treatment for cerebellitis, its outcome is usually favourable. We report two cases of AC in the paediatric age group, successfully managed with long tunnel external ventricular drain (EVD). The first patient was an 8-year-old boy with a history of fever and headache. Sequential MRI showed diffuse cerebellar swelling with tonsillar herniation and resulting hydrocephalus. The second patient was a 6-month-old boy who presented with high-grade fever associated with chills. CT scan of the head showed triventricular hydrocephalus with obliteration of cerebrospinal fluid spaces and …
