Case 1 71 y/o woman with HTN and asthma February 2015 Just another - PowerPoint PPT Presentation

Case 1 71 y/o woman with HTN and asthma • February 2015 Just another neuropathy? • Suddenly noted she couldn’t write with her right What not to miss. hand. No pain. Could not feel pain if she cut herself • One week later, left foot started to flop and worsened over several days Ann Poncelet, MD Professor of Neurology • Several days later, left hand became weak and William G. Irwin Endowed Chair numb 2/15/2018 • Several days later, right foot gave out Case 1 Case 1 • March 2015 • April 2015 • Admitted to OSH with diagnosis of Guillian Barre • Progressed to being wheelchair bound Syndrome • NCS by local neurologist showed no motor or • CSF with negative gram stain and culture, WBC sensory responses in legs. Arms not tested. 0, RBC 9. Glucose 61. TP 38. HSV prc neg. West nile IgG and IgM neg. • May 2015 • Treated with IVIg but no response to treatment. • Treated again with IVIg but no improvement • Discharged to home • Neuropathy stopped progressing at this point 1

Case 1 Review of Systems • April 2015 and July 2015 Gen: (+) 40lb weight loss (-) fevers, chills, malaise, diaphoresis • Asthma attacks treated with prednisone taper. HEENT: (+) oral ulcers (-) congestion, hearing changes,nose bleeds, Improved breathing but no effect on neuropathy vertigo, hoarseness, changes in vision, photphopbia/diplopia • August 2015 Resp: (+) cough/wheeze, scant yellow phlegm. (-) hemoptysis/dyspnea • Right index finger tip became discolored and CV: (-) chest pain, palpitations, orthopnea progressively darker GI: (-) n/v/d/c • Admitted to OSH for further evaluation GU: (-) hematuria/dysuria • Had multiple tests, consults with oncology, MSK: (-) arthralgias, myalgias, back/neck pain gastroenterology without a clear diagnosis and Neuro: (+) weakness/numbness of bilateral hands and feet. (-) recommendation to see a vascular specialist seizure, syncope, headaches • Left AMA to have appointment in neuromuscular Heme: (-) bruising/bleeding clinic at UCSF Oropharynx exam Skin Exam 2
