UNIVERSITY OF NEBRASKA MEDICAL CENTER
Governor Heineman speaks on Bioterrorism Preparedness
Lectureships are amongst the premiere
events of an academic institution, and we
are privileged this year to have had an
outstanding individual presenting at this
year’s Harry W. McFadden, Jr., M.D.
Lectureship on April 14, 2005, the
Honorable Dave Heineman, Governor of
the State of Nebraska.
Governor Heineman was sworn in
as Nebraska’s 39th Governor on Friday,
January 21, 2005. Prior to becoming
Governor, he served more than three
years as Lieutenant Governor.
As
Governor Heineman
Nebraska’s director of homeland security,
chairman of the Nebraska Information Technology Commission
(NITC), and the presiding officer of the Nebraska Legislature.
Governor Heineman’s lecture on “Building on the Nebraska
Model for Bioterrorism Preparedness” focused on the
extraordinary job Nebraska has done relative to bioterrorism
preparedness. This all began in 1997 with the move of the
Nebraska public health lab to UNMC.
Governor Heineman praised UNMC’s role in advancing the
Nebraska Model, “an integrated, coordinated and comprehensive”
preparedness plan that spans everything from information
technology and transportation to agriculture and academia.
The Harry W. McFadden, Jr., M.D. Lectureship was
established in 1985 upon his retirement as Chairman of the
Department of Medical Microbiology. Dr. McFadden was a
graduate of the Nebraska College of Medicine in 1943. After
completing his training in pathology, he became a faculty member
at UNMC where he rose to the rank of full professor and became
Chairman of the Department of Medical Microbiology in 1956. He
held that position for nearly 30 years until his retirement in 1985,
at which time the department was merged with Department of
Pathology and Laboratory Medicine to become the current
Department of Pathology and Microbiology. At that time, the
pathologists of the department contributed an endowment to
establish this lectureship. Dr. McFadden has had numerous
awards and recognitions for his many contributions to
microbiology, pathology, and most notably to medical education.
It is for his contributions as an outstanding educator of medial
students. The alumni of the Class of 1964, on their 25th reunion,
decided to further endow the McFadden Lectureship, making it a
premier event at UNMC.
A few of the distinguished guests at the celebration
dinner the evening before were, Governor Heineman and
his wife, Sally Ganem; Senator Abbie Cornett and her
husband, Mark Stranglen; Senator Gwen Howard and her
daughter, Carrie; Senator Pam Brown; Senator Lowen
Kruse and his wife, Ruth; Dr. Dick Raymond, Chief Medical
Officer for the State of Nebraska; Dr. Steve Hinrichs,
director of the University’s Biosecurity program and his
wife, Deb; Regent Dr. Drew Miller and his wife, Annabeth;
Regent Dr. Randy Ferlic; Alumni for the Class of 1964
Nebraska College of Medicine; Dr. Chet Thompson and his
wife, Barbara; Dr. Vale Sorensen and his wife, Peggy; and
Dr. Cleve Trimble.

Letter from the Chairman
Another academic year is about to begin, with the conclusion of an exciting year in our department and on
campus. Important events have occurred in our department involving all our missions, including education,
research, and clinical service.
A significant effort in the past several months has revolved around planning for a new Bioterrorism
Preparedness Laboratory, including new laboratories for research, and planning for a new clinical laboratory.
The efforts of numerous individuals are involved in this process as it continues. This project will follow on
the-soon-to-be completed opening of the Center of Excellence Building, which will include a new, modern and
expanded operating room suite and a new gross and frozen section room for pathology.
The clinical laboratory also recently completed a successful CAP inspection. Congratulations to all those involved with this major effort.

Biocontainment Unit Unveiled
On March 7, 2005, Julie Gerberding,
M.D., director of the Centers for Disease
Control and Prevention (CDC), unveiled
Nebraska’s new Biocontainment Unit at
The Nebraska Medical Center.
“Nebraska is leading the way (in
bioterrorism preparedness) and the
biocontainment unit is one stellar example
of that kind of preparedness,” Dr.
Gerberding said. The 10-bed unit, set up
to handle highly contagious and deadly
Julie Gerberding, M.D. infectious conditions, is the first-of-its-kind
in the nation. “We do not have any other
capacity like this in the nation,” Dr. Gerberding said. “Part of the
beauty of this particular facility is that it would serve not only for
Nebraska, but for the other states that are engaged in the
Midwest Alliance.” The unit is equipped with special air-handling
systems to ensure that germs do not spread beyond the patients
rooms. Ultraviolet light, a dunk tank for lab specimens and
sterilizer for items to be taken out of the unit are just some of the
safety features designed to keep germs inside the unit and protect
people on the outside. The unit also has two videophones that
would give families and friends a connection to loved ones inside
the unit. The videophones also will make consultations easier
and safer.
The unit is set up to handle a wide variety of contagious and
deadly infectious conditions, including the following hazardous
diseases: small pox, anthrax, tularemia, the plague, botulism,
SARS, monkey pox, avian flu, vancomycin-resistant staph
infection, viral hemorrhagic fevers, and antibiotic-resistant tuberculosis.
There are only two other

infectious agents, and the CDC has a
two-bed unit at Emory University Hospital in Atlanta.
Dr. Gerberding praised the leadership of Nebraska, which is
recognized nationally for its collaboration on bioterrorism
preparedness issues, calling it a model for the nation. Governor
Dave Heineman says, “Nebraska is a leader in bioterrorism
preparedness and this collaborative effort is another shining
example of what can be accomplished by working together.” The
funding comes from federal bioterrorism preparedness dollars
allocated to Nebraska, along with contributions from The
Nebraska Medical Center and UNMC. Each state received funds
to plan and develop bioterrorism projects.
Nebraska’s success, Gerberding said, has evolved from
established priorities, phenomenal performance and leadership,
vision and passion of state leaders to execute the job. Steve
Hinrichs, M.D., professor of Pathology and Microbiology and
director of the University of Nebraska Center for Biosecurity, says
having the Biocontainment Unit and the Nebraska Public Health
Laboratory located in the same area is an important benefit to the
state. “The Nebraska Public Health Laboratory brings state and
university expertise and resources together in a collaborative
effort,” Dr. Hinrichs says. “The laboratory’s nearby location
provides state-of-the-art services and enhances our overall preparedness for the threat of bioterrorism and infectious disease
threats.”
Philip Smith, M.D., medical director of the biocontainment unit, says, “The unit is a valuable regional and potentially national resource that is unique because of its 10-bed
size and because it is a health department initiate project with
collaboration between public health, a university and a
hospital.”
“This unit gives testimony to what can happen through
collaboration,” Glenn Fosdick, President and Chief Executive
Officer of The Nebraska Medical Center, said. “A hospital alone cannot do

wage a bedside battle with the most contagious and deadly
disease in the world. I want you to see the faces of courage
– the people who’ve come to us and said, “I want this job”.
“Since 2002, the four campuses of the University of
Nebraska have worked together on terrorism research
through a Center for Biosecurity administered by the
University of Nebraska Medical Center,” Governor Heineman said. “UNMC has earned praise over and over again for
its caliber of research. It leads the way in developing technology to detect and react to a biological attack. State government’s unique collaboration with UNMC and other partners
makes very, very good sense.”

funds Research project
The Microbiology Automations
Research Project (MARP),
directed by Dr. Rod Markin
received funding from the
Department of Defense (DoD)
in October 2004. The objective of the MARP is to
develop a broad microbiology
(including bacteriology,
mycology, and virology)
MARP Team
automation platform that will
allow for and support the
creation of an automated microbiology technology that can
be used by the Army in the clinical laboratory. It can also be
used for non-clinical microbiology applications, potentially
including bioterrorism testing.
The project will evaluate certain types of known
microbiology specimen container systems for automation. At
the conclusion of the grant, MARP should be able to
dramatically improve how microbiology specimens are
processed and cultured.
There are tangible and intangible benefits of the Project.
The tangible benefits include a reduction in DoD healthcare
costs, 24-hour/7-day-a-week operations and production,
extremely quick turn-around times (critical in field settings),
decreased errors and increased quality through repetitive and
standardized processes. This means more troops can be
processed more quickly, more ambient air samples can be
tested, and more work can be done on site, all with less
training than might otherwise be needed. Intangible benefits
include advancing systems engineering for other applications
and gradually standardizing specimen handling and
processing.
Update
Additional laboratory working space for the Special Pathogens
and Biosecurity Laboratory sections of the Nebraska Public
Health Laboratory (NPHL) in Wittson Hall was completed and
officially opened on January 20, 2005. In addition to the
Biosecurity and Special Pathogens Laboratory sections, the
Chemical Terrorism Preparedness Laboratory (CTPL) is also
located here. The new space gives these NPHL laboratory
sections substantially more area to continue developing the
capability and capacity necessary for public health related
testing. This capacity has been developed to provide testing in
a variety of situations, from suspected biological or chemical
terrorism events to West Nile virus testing.
The Biosecurity and Special Pathogens Laboratory
sections of the NPHL have the capacity and capability to test for
a variety of bacterial agents by culture, DNA detection by
polymerase chain reaction, or by detection of whole bacteria or
biotoxins by an enzyme-linked immunoassay (ELISA) test
known as time-resolved fluorescence (TRF). (See Table 1). As
new assays are developed and released by the Centers for
Disease Control and Prevention, the NPHL will continue to
receive the testing kits and diagnostic reagents needed to
perform the assays.

Researchers Discover Unknown Bacteria
After four cancer patients in five years
contracted the same mysterious,
life-threatening lung infection, a UNMC
cancer physician wanted to know exactly
what bacteria was causing the infection.
Knowing would give him a better idea of
how to more effectively treat the infection.
Employing molecular diagnostics to
solve the mystery, UNMC microbiologists
and laboratory specialists at The Nebraska Medical Center accomplished
something prestigious in the world of microbiology. They identified a previously
unknown organism and named it Nebraskense (pronounced neh-brah-SKENNebraskense
see) after the state.
“This may not be equivalent to discovering a new planet, but for biologists, it’s very exciting,” said
Steven Hinrichs, M.D, UNMC professor of Pathology and Microbiology and director of The
Nebraska Medical Center microbiology and virology laboratories. “This bacterium wasn’t just
created. It’s just that it hasn’t been recognized before. It’s
probably been around for a long time.”
The organism, called Mycobacterium Nebraskense, is in a
family called Mycobacterium, which include diseases like tuberculosis and leprosy. Nebraskense, a new bacterium species
commonly found in soil and water, is slow growing and is known
to cause chronic lung infection, including pneumonia.
The UNMC discovery will allow laboratory specialists
around the world to identify the organism faster and earlier, enabling health professionals to use the most appropriate treatment. Dr. Hinrichs says treatment is the key because the organism is almost impossible to avoid.
Gail Woods, M.D., professor of pathology at the University
of Utah, and a scientist with Associated Regional and University
Pathologists, Inc., said the Nebraska discovery solved a mystery for her laboratory. “We had the isolate but couldn’t identify
it,” Dr. Woods said. “We didn’t know what it was. Once we had
the information, we added it to our database. The discovery will
allow scientists to learn more about the disease it causes.”
“Within each organism’s DNA, there are signature sequences areas that are unique to the organism,” Peter Iwen,
Ph.D., associate professor in the UNMC Department of Pathology and Microbiology said. “There are multiple signature sequences that can be used for identification purposes. The signatures we have identified are somewhat unique and found to
be reliable for identification purposes. A test we’ve developed
allows us to look at the unique sequence in the genetic material
of an organism and identify the species.”
The team is also working on developing the ability to
“direct test” patient specimens – making identification available
between a matter of hours and a couple of days, instead of
taking a month or longer as currently required. In addition, scientists also are looking to develop tests to determine the resistance of bacteria to certain drugs.
“Health professionals routinely prescribe treatments before they know the organism causing the disease,” Dr. Iwen
said. “They don’t always know what’s wrong. Some ask, why
worry about obscure organisms that are difficult to identify?”
The answer is: because frequently, they require different treatments.”
From their work on the project, researchers have patented a molecular diagnostic test kit and are applying for
patents on others they’re developing. The kits enable more
rapid and accurate ways to diagnose disease. Laboratories
performing diagnostic testing for micro-organisms, including
human and animal, are potential users of the test kits.
“Our capability in virology and molecular diagnostics is
probably only exceeded by places like Mayo Clinic, Baylor,
and a couple of national laboratories,“ Dr. Hinrichs said.
“Most labs don’t employ these methods. We’re just beginning to see the vast potential of this technology. It’s faster
and more accurate and has the ability to reveal aspects of
bacteria such as whether it has antibiotic resistance. It will
revolutionize microbiology.”

David T. Purtilo, M.D.
On January 8, 2005, the department celebrated the naming of
Dr. Rodney S. Markin as the David T. Purtilo Chair of
Pathology. The Chair is in honor of Dr. David T. Purtilo,
Chairman of the Department of Pathology and Microbiology
at UNMC from 1981 to his untimely death in 1992 at the age
of 53. David had the wisdom and foresight to establish a
major program funded by contributions from the faculty
members of the department establishing insurance policies
on themselves for future endowments. Ultimately, this
program will endow 14 chairs or professorships for the
department.
Dr. Markin was recruited as a resident by Dr. Purtilo in
the department and ultimately as a faculty member. It was
one of many outstanding recruitments by Dr. Purtilo in
changing the department from a clinical and teaching entity to
a major academic department with significant extramural
research funding for clinical and basic research.
Dr. Markin has an unusual combination of backgrounds
including a Ph.D. in chemistry, board certification in anatomic
and clinical pathology, and special expertise in
hematopathology in anatomic pathology and clinical
chemistry, laboratory automation, and laboratory information
systems in clinical pathology. His research has involved all of
these areas, but he is best known for his development for
laboratory automation systems, including his recent
endeavors in automating processes for microbiology testing,
particularly as it could be related to bioterrorism
preparedness.
At the celebration dinner at Happy Hollow Country Club,
he was joined by his wife, Annette, his two sons, Nicholas
and Christopher, his father and other family members, friends
and faculty colleagues.
Dr. Rod Markin epitomizes the vision of excellence in
academic pathology anticipated and expected by Dr. Purtilo,
and it is a pleasure and honor to name him as the David T.
Purtilo Chair in Pathology.

Schenken Award Goes to
Three Recipients
Pathology Residents Corner
Three UNMC students received the 2005 J. R. Schenken M.D.
Outstanding Achievement in Pathology and Microbiology Award
during the honors convocation on May 12, 2005.
The
Schenken Award is presented to outstanding medical students
in honor of Dr. Jerald R. Schenken, a nationally recognized
pathologist. The award is presented to those medical students
who best exemplify scholarship and professionalism in
Pathology and Microbiology during their
medical school
careers.
The past six months have been a very busy and productive time
for our residency program. The largest project was preparation for
the ACGME residency accreditation site visit which took place on
February 23, 2005. We would like to extend a big thank you to all
the faculty, residents and staff who worked so hard in preparation
for this day. At this time, we do not anticipate receiving feedback
on our residency program until next fall. Until then we will diligently
continue working on several goals including re-designing the
residency web site, rewriting the residency manual, and residency
recruitment will be our major focus for 2005.
Dr. Schenken, who practiced pathology at Methodist
Hospital in Omaha, was involved with UNMC from 1965 until his
death in 2001.
This award recognizes Dr. Schenken’s
contributions to the education of future physicians and medical
technologists and to the continuing education of health
professionals. Since Dr. Schenken was involved in medical
education broadly, the awards are not limited to individuals
going into pathology. The winners this year and their residency
plans are:
•
Michael Feilmeier: Ophthalmology
University of Miami/Bascom Palmer Eye Institute, Miami, FL
•
Stephen Schinker: Internal Medicine
University of Texas Health Science Center, San Antonio, TX
•
It is with pleasure that we announce Dr. John Gentry has
agreed to serve as the Chief Resident for the 2005-2006 academic
year. We would like to thank our current Chief, Dr. Rachel Stevens
for a job well done. Her work and ideas this past year have been
integral to many improvements in the program. In addition, Dr. Kurt
Mathews also deserves a thank you for his involvement as Chief

Department Has Strong
Presence at USCAP
The largest meeting of anatomic pathologists in the United
States was held in San Antonio, Texas during the first week of
March. Historically, the United States and Canadian Academy
of Pathology (USCAP) has been a favorite venue for the UNMC
Department of Pathology & Microbiology. This year was no
exception. The department was recognized as one of the top
20 departments, out of two hundred twenty departments, for the
number of posters and presentations by our residents, fellows
and faculty at the meeting. Our strong presence at this meeting
reflects the diverse research endeavors of our department.
This only scratches the surface of the accomplishments our
residents have had in the past 6 months. We look forward to
reporting even more exciting resident activities and
accomplishments in the months to come.

UNMC Research May Help Fight Prostate Cancer
metastasis from
occurring. ”
MMP-7 is an enzyme that
regulates communication between
the tumor and surrounding normal
tissue by processing cytokines and
growth factors to active forms.
MMP-7 has been shown to be
involved in the invasion and spread
of several cancers.
The researchers found that
MMP-7 cleaved a molecule called
RANKL into a soluble form that
promoted osteoclast activation and
bone degradation. Mice deficient in
MMP-7 had little to no soluble RANKL and exhibited substantially reduced prostate cancer-induced bone degradation compared to control mice expressing MMP-7.
The researchers conclude that MMP-7 plays a major role
in prostate cancer-driven osteolysis and that the mechanism of
MMP-7 action involves cleavage of RANKL to a soluble form
that promotes osteoclast activation and pathological bone
breakdown. "Our results make MMP-7 an attractive
therapeutic target for the control of prostate cancer-induced
bone osteolysis," Dr. Futakuchi said.
Dr. Singh said the next step will be for researchers to
extend the study to breast cancer. He said prostate and breast
cancer are most likely to spread to the bones. In approximately
60 percent of patients with metastatic prostate or breast
cancer, the metastasis occurs in the bone.
"This is all about quality of life," Dr. Singh said. "Bone
cancer is very painful and treatment options are lacking. We
now need to look at these regulators of bone metastasis and
try to develop targeted therapeutics that will prevent the bone
metastasis from occurring."

The findings provide critical insight

bone disease caused by the spread of
prostate cancer. The research is published in the cover story in
the May 2005 issue of Cancer Cell, a premier scientific journal.
The spread of cancer to other body regions is the primary
cause of death from prostate cancer. The most common place
for prostate cancer to metastasize is bone, causing intense pain,
pathological fracture, and immobility. At the current time,
treatment options for patients with bone metastases are limited.
Rakesh Singh, Ph.D., associate professor of pathology and
microbiology, and Mitsuru Futakuchi, Ph.D., a post doctoral
research fellow, headed the collaborative study between UNMC,
Vanderbilt University and Nagoya City University in Nagoya,
Japan. Dr. Singh is the principal investigator. Dr. Futakuchi is a
visiting postdoctoral fellow from Japan. Lynn Matrisian, Ph.D.,
chair of the department of cancer biology at Vanderbilt University,
also was a key participant in the study.
The study, which has been ongoing for the past five years,
used a new rodent model that mimics the changes to bone that
occur following prostate cancer metastasis.
Transplantation of prostate tumor tissue onto bone surfaces
provided a histological picture similar to human prostate cancers
growing in the bone. The goal of the study was to look for
mechanisms that drive the behavior of this disease, with the hope
of discovering new therapeutic targets.
"Bone remodeling is always going on in the body. It's a
natural process," said Dr. Singh. "What we found is that for the
metastatic tumor to grow in the bone, it must exploit the normal
bone remodeling process by using the same pathway."
Dr. Futakuchi said: "Bone is not a very fun place for cancer
to grow. For tumor cells to grow in the bone, a vicious cycle must
occur involving bone destruction and the release of growth
factors necessary for tumor cell growth. The destruction must
occur, because the tumor needs the space to grow."

Mary Haven to Retire
When Mary Haven was named associate dean of UNMC’s School of Allied Health Professions in 1995,
she had an idea of how long she’d stay in the position. She thought 10 years would be a good time to be
associate dean and see things through, then time for new ideas.
“Haven joined UNMC on March 1, 1968, as a clinical chemist in pathology/microbiology and medical
technology. “Mary Haven has been a part of the gyroscope that has kept our department, the clinical
laboratory and the Allied Health programs on course during her tenure at UNMC. We have all been
educated through one venue or another by Mary. I have personally enjoyed working with her both in the
department and the College of Medicine over the years,” says vice-chairman Dr. Rodney Markin. When
accepting the associate dean position, she succeeded Reba Benschoter, Ph.D., who also spent 10 years
in the role.
During Haven’s tenure, she has expanded the distance learning programs beyond that of most allied
health schools and colleges. By this fall, SAHP will have four programs offered by distance learning: medical technology,
radiation therapy, radiography and cytotechnology. She became nationally recognized for her work and research in clinical
chemistry and her contributions to education. “She is one of the most remarkable individuals I have known,” declared department
chair Dr. Sam Cohen.
Upon retiring, Haven and her husband, UNMC ophthalmologist Gerald Christensen, M.D., plan to travel. She also intends
to stay involved with international programs at the medical center.
