Case Presentation
Diagnostic Results (February 2014):
EEG: unremarkable; no seizure activity; no slowing
MRI Brain: Extensive confluent white matter disease in both cerebral hemispheres,
nonspecific in appearance. Demyelinating or dysmyelinating processes should be
considered. Vascular processes such as small vessel ischemic change or vasculitis should
also be considered. No mass or abnormal enhancement noted. Prominent cisterna magna
versus small retrocerebellar arachnoid cyst. (unremarkable)
MRI Brain Spectography: Spectra overall fairly unremarkable. There is no significant
choline elevation or NA depression. No findings to suggest a highly metabolic or rapidly
dividing cellular process such as a higher grade malignancy is evident. Demyelinating
pathology can sometimes have choline elevation and again there is no significant choline
elevation throughout the hemispheric white matter abnormality.
CSF: unremarkable except for highly elevated TAU protein of 1929 pg/mL, ambigous 14-33 protein levels, and positive Rt-QuIC test.
Lab work: unremarkable except for an elevated cholesterol level of 217.
Differential Diagnosis
Alzheimer’s Disease
Dementia with Lewy Bodies
Frontotemporal Dementia
Meningoencephalitis
Corticobasal Degeneration
Progressive Supranuclear Palsy
CVA
Seizures
Opioid withdrawal
OR………….
Diagnosis: Creutzfeldt Jakob Disease
(CJD)
(probable)
Neurology follow up visit:
Probable CJD
CSF sent to National Prion Disease Pathology Surveillance Center
TAU Protein highly elevated (neuronal microtubules stabilization)
Ambiguous 14-3-3 protein (surrogate markers of neuronal damage – not specific for sCJD)
Positive Rt-QuIC test (specific for sCJD)
BUT…
No known exposure base on history
No blood transfusions
No transplants
Lives close to a cattle farm but no exposure to slaughter house
Diagnosis:
Very early stages of probable CJD
Definitive diagnosis: BRAIN BIOPSY
Plan:
Repeat EEG and MRI in two months
Follow up Neurology 2 months
Creutzfeldt Jakob Disease
First reported by German Neurologists:
Hans Gerhard Creutzfeldt in 1920
Shortly thereafter by Alfons Maria Jakob
Creutzfeldt Jakob Disease
Transmissible Spongiform Encephalopathy's (TSE’s):
Also known as prion diseases
Proteinaceous infectious particle – infected protein that folds
Causes other proteins to fold – damages neurons
Rare degenerative brain disorder
Characterized by tiny holes that give the brain a spongy appearance:
CJD is the most well-known of the human TSE’s or prion diseases
Other Human prion diseases:
Kuru – found in a isolated tribe in Papua New Guinea (extinct)
Variant CJD (vCJD)
Animal prion diseases:
Bovine spongiform encephalopathy's (BSE’s):
Mad Cow Disease
Scrapie – sheep and goats
Chronic Wasting Disease – elk and deer
Creutzfeldt Jakob Disease
Creutzfeldt Jakob Disease
Creutzfeldt Jakob Disease
Incidence:
World wide 1-2 in 1 million
In US ~300 cases per year
Age of onset: 60
90% die within a year
Diagnosis is difficult
Low index of suspicion
Lack of knowledge of this rare disease
Long incubation period (vCJD)
Creutzfeldt Jakob Disease
Three major categories of CJD:
Sporadic 80%
Hereditary 3-10%
Acquired <1%
most common
Sporadic – occurs for no apparent reason
Inherited or familial – family history / genetic mutation
Acquired r/t Contamination - exposed to contaminated
human tissue
Cornea/skin transplant/brain surgery
Variant linked to beef infected with BSE (Bovine
Spongiform Encephalopathy)
Creutzfeldt Jakob Disease
Clinical features:
Rapidly progressive dementia
Multifocal neurological findings:
Myoclonus
Visual disturbances
Cerebellar and pyramidal / extrapyramidal signs
Rapid progression of cognitive and functional
impairment toward akinetic mutism and
eventual death within 6 months to 1 year.
Creutzfeldt Jakob Disease
Treatment:
• There is no known cure or effective treatment for
CJD. However, medications can be used to treat
some of the mental changes and personality
abnormalities that occur. Treatment is usually
focused on making patients comfortable and to
help them function safely in their environment.

CJD: The Role of Infection
Control & Prevention
Deb Hess RN, CIC
Role of Infection Control
Received call from Trauma Coordinator:
• Possible CJD gunshot wound to head
• What do we need to know or do that is
different from our standard of care?
All hands on deck!
• All Infection Control Nurses were given a task
using the “divide and conquer” methodology
Access before you Act
• Paged LGHP-ID physicians (Dr. Riley & Dr. Kontra)
• Promptly identified that this was a true case
– Electronic health record across the Alliance provided
access to outpatient & specialists records because
the providers were part of LG
• Other IC nurses were pulling guidelines and
standards from Centers for Disease Control
(CDC), World Health Organization (WHO), and
American Association for Infection Control &
Epidemiology (APIC)
Identified Key Information
• Brain matter highly contagious; given gunshot wound to
head, needed to protect our employees.
• (Considered blood to be contaminated with brain
tissue)
• Promptly sent one IC Nurse to EMD to assist with
verification that proper PPE was being worn!
Standard Precautions
• Blood or body fluid potential exposure; wear PPE.
• Trauma with excessive bleeding; Impervious gowns
• Potential of splatter; wear mask & eye protection
• Need for containment of all equipment and supplies within
trauma bay to determine appropriate cleaning or disposal
Identified that others needed “to know” & help needed!
• Director of IC & EMD notified
• Director of Quality and Patient Safety notified
• Senior Vice President of Operations notified
• Risk Management notified
• Director Environment Services notified
• Brought expertise & “workers” to scene
Ambulance & Crew
• How to decontaminate?
• Ambulance taken out of service – Instructed not
to leave until further direction provided
CT scan of head performed:
• Confirmed that death would occur
• Family requested life support be continued
Chaplain
until others arrived
Need for containment of all equipment
and supplies taken into CT Room
• Patient admitted to Trauma Neuro Unit (TNU)
Nursing
from CT scan room
Adm.
Trauma
team
Notify TNU of diagnosis; remove unnecessary
supplies within room before patient arrival.
• Another area requiring containment of in room
Safety
supplies & equipment
Officer
Supply & Equipment Management
All equipment that could not be decontaminated with bleach
(1:5 ratio) for 60 minutes would require incineration
•
Identified per CDC, WHO & APIC guidelines
Infection Control Physicians & Nurse Manager did a systematic
approach to the environment:
Is item able to be cleaned with bleach?
• If yes - “one bucket”
• If no – “second bucket for incineration”
• Log items to be incinerated and owner as required
replacement
Surfaces cleaned with Bleach – 1 hour exposure (Close Vents in
area to protect other hospital areas from bleach odor)

Safety
• HazMat notified and decontaminated room where
incident occurred
Notified
PA DOH
Pa Department of Health
• CJD is reportable disease – Instructed to follow CDC
Guidelines (we were already doing that)
CDC
Family reported to IC that they were previously
told that the CDC “wanted his brain”
IC Manager called CDC - Connected to Emergency Operations transferred to Dr. Ryan Maddox of the Prion Division –
instructed us to call National Prion Disease Pathology
Surveillance Center in Cleveland Ohio for review of case.
Coroner
Notified coroner of planned events
Patient: Support withdrawn the following day and
patient expired soon thereafter.
Nursing
consideration
TNU staff wrapped head in several pads
to prevent pooling of blood within body bag.
Brain Harvest Requested by National Prion Disease Pathology Center
• Autopsy to be done free of charge for confirmation of diagnosis
• LGH refers autopsy requests to Hershey Medical Center (HMC)
– Refused to perform autopsy due to risk
• Called Coroner
– Refused as they legally can only do autopsy when cause of
death unknown
Identified Funeral Home:
Funeral
Director
– Provided funeral director with CDC
guidelines for “Funeral Directors”
PR
Public relations:
• Family concerned about “news coverage” of incident
• Team met and prepared statement and talking points
in the event LGH was contacted to make a statement.
Family’s wishes for privacy honored with no case
specific information / identity to be shared
Emotional Toll of Healthcare Workers
• Two hospital minor exposures – occurred prior to
identification of diagnosis
• All involved felt the emotional impact – we provide
care in a dangerous environment
Financial toll:
• Multiple items were unable to be bleached
• Incinerated items from LEMSA, EMD, and personal
clothing/stethoscopes
• Cost was in the thousands of $$$$
• Debriefing
• Several weeks later, called team together to review
case. Included all involved except family.
• Reviewed what happened
• Reassured all that CDC & Centers for Prion diseases
were involved behind the scenes from the beginning.
• They stated that we went “above and
beyond” to protect everyone
• “We were in unchartered territory”!
Lessons Learned
• Demonstrated the Value of Electronic Medical Record –
diagnosis was identified early in care
• Do we need to place CJD in the header; so it is seen
immediately? Yes
• Reviewed Exposure Policy – currently under revision
• Reinforced need for impervious gown use in trauma
bay
• Need greater awareness of splash potential; use of
goggles/eyewear protection
• Gloves: Switching to higher quality to prevent tears
and better wrist coverage
