Building Bridges: Connecting at Risk Women to Mammography via Emergency
Department Visits
INTRODUCTION: Women presenting to the ED, who had not had a recent screening
mammogram, were given educational materials and referred to free mammography. We then
measured their rate of scheduling a mammogram within 1 month.
HYPOTHESIS: Providing at risk women with educational materials and referral for free
mammography will not improve their rate of obtaining a mammogram within 1 month of
discharge.
METHODS: In this prospective, controlled study, a survey regarding mammogram use, and
breast cancer awareness was verbally given to women over 40 in the ED, and 1 month later by
phone. The intervention group (n=200) received pamphlets about breast cancer prevention plus
phone numbers for a free mammogram at community health departments; awareness posters
were also placed in the ED waiting room. A similar group (n=200, controls) also responded to
the survey in the ED and 1 month later by phone, but without any intervention.
RESULTS: Of the 131 women needing mammograms enrolled in the educational intervention,
97 (74.0%) were reached by phone, and 21.6% had obtained or scheduled a mammogram in the
month after discharge. Of the
111 women needing
mammograms enrolled in the
control group, 88 (79.3%)
were reached by phone, only
3.4% had obtained a
mammogram in the month
after discharge (Fisher’s Exact
Test, p < .0005).
CONCLUSIONS: At risk women less likely to have access to reliable health care responded to
an educational intervention and awareness of free/reduced cost resources by complying with
ACS breast cancer screening guidelines. The ED provides a unique setting in which to promote
such preventative measures to women most in need.

Leading Reasons why Abstracts are Rejected
•The primary author is the individual who has contributed the greatest amount of work and intellectual effort to the project
•The primary author should be listed first and the name should appear in bold face font/underlined (in keeping with the indicated abstract format)
•Keep the number of authors to a minimum. The maximum number may be defined by the journal or society
•All authors appearing on the abstract are responsible for the content of the abstract and the veracity of the work it describes
Authors and Ethics
•Only individuals who have made a substantive contribution to the work should appear as an author-ghost authorships are not appropriate
•Decide in advance who will appear on the abstract and the order of their appearance
•Generally, only original abstracts not previously presented at other meetings or published will be accepted-check with the individual medical society for exceptions to this
•Beware of “cut and paste” plagiarism

Scientific Abstract Checklist
FIREWORKS STRESS PREGNANT MARES
To examine whether the stress of fireworks noise could disrupt
reproductive function, Prolactin (PRL), epinephrine (EPI) and progesterone (P)
were measured acutely in the plasma of pregnant mares at intervals prior to and
following the annual fireworks celebration in Philadelphia. Blood samples were
drawn from an indwelling catheter placed in the jugular vein by 4 pm July 4th
and shielded with a protective collar. At -2 hr, an extension was attached to each
catheter and led out of the stall. Blood was drawn from 6 Arabian mares early
in pregnancy (4-6 weeks). They were housed within 2 miles of the fireworks site
and bled at -30, 0, +2, +5, +10, +20 and +60 minutes in relation to the scheduled
initial fireworks (10 pm). All horses were agitated throughout the 15 minute
fireworks. Hormonal values (mean SE) are shown below.

As expected, EPI and PRL surged in response to the fireworks, although
EPI peaked earlier and remained more elevated than PRL. P increased
moderately, most probably due to adrenal release.
We conclude that the stress of the fireworks’ noise increased circulating
E and PRL. While all mares delivered healthy foals at the expected times, the
long term effects of such transient stress hormonal alterations on dam and foal
are unclear.
Which Would You Read First?Comparison of Allogenic Bone Screws with Bioabsorbable and Stainless
Steel Screws
Abstract O8.
Newly developed allogenic bone screws have yet to be compared to stainless steel and
bioabsorbable screws for their resistance tos breaking and bending, important factors in
fixating osteotomies and fractures. We tested the hypothesis that allogenic bone screws exhibit
greater stiffness and torque than established screws. Using an Instron™ device, in vitro studies
in shear resistance and bending were performed. Twelve allogenic bone and 12 bioabsorbable
3.5mm screws were tested against equal length stainless steel screws.
Bending Shear
Seconds to Failure Load (N) at Failure Seconds to Failure Load (N) at Failure
Allogenic Bone 53.45 4.81* 4.73 0.03* 14.73 0.09* 310.66 9.91**

Stainless Steel 123.45 21.30*** 63.06 9.12*** 26.57 8.18* 710.62 195.96*
within the same column, different superscripts (such as * and **) are different (p < .03, ANOVA)
In the bending test, allogenic bone screws failed faster and at markedly smaller loads. In the
shear test, allogenic bone failed at approximately half the load of stainless steel or
bioabsorbable screws (see graphs). Thus, allogenic bone screws do not exhibit greater stiffness
and torque than stainless steel and bioabsorbable screws. This determination of relative
resistance to binding and shear will help podiatric surgeons select the best screw for the
osteotomy or fracture being repaired.

Cryogenic Denervation for the Treatment of Lower Extremity Neuromas
Foot pain from neuromas can become debilitating, limiting patients’
activities. When conservative treatment fails, the neuroma is excised. However,
the failure rate of surgical neurectomies exceeds 20%. To examine whether
cryogenic denervation blocks neuroma pain, 20 surgical candidates consented to
experimental treatment by cryoprobe denervation.
Thirty-one neuromas were denervated using a Westco cryoneedle insterted
percu-taneously. The activated cyroprobe damages endoneural capillaries
initiating demyelinization and axonal degeneration. Neuromas were subjected to
two three-minute freeze cycles at –70 C with a 30 second thaw in between.
Post-operatively, all patients resumed normal activity immediately. However, 2
weeks after intervention, patients fell into 3 groups: pain free (n = 11); partial
pain (15) or full pain (5). Pain ratings for these groups differed (partial vs. full,
p < .002; pain free vs. partial and full pain, p < .04). Thus cryoprobe treatment
was completely effective for 35.5% of these patients while it failed totally for
16.1%.

While direct comparison to surgery will require a randomized clinical trial,
these results suggest that cryosurgery has a failure rate similar to surgery but
provides at least temporary respite from neuroma pain and can be totally
effective for some patients.
Associations between cigarette smoking and each of 21 types of cancer: a multi-
site case-control study.
BACKGROUND. Although the effects of cigarette smoking on cancer risk have been
well documented, several outstanding issues remain to be clarified, including which
types of cancer are associated with smoking and estimating the magnitude of the
effect of smoking on different types of cancer. A further issue is whether the effects
seen elsewhere can be demonstrated in Canada, where tobacco products differ
somewhat from those in other countries. METHODS. A case-control study was
undertaken in Montreal to investigate the associations between environmental and
occupational exposure and several types of cancer. Between 1979 and 1985, male
patients with 21 types of cancer, including 15 anatomical sites, were interviewed to
obtain detailed information on smoking histories, job histories, and other potential
confounders. A total of 3730 cancer patients and 533 population controls were
interviewed. For each type of cancer, two groups acted as controls: population and
cancer controls (from other cancer patients). The purpose of our analysis is to
estimate the relative risk of each selected cancer in relation to smoking and to
estimate the % of cancer cases attributable to cigarette smoking. RESULTS.
Separate analyses conducted with the two control groups produced similar results. Of
the sites examined, colon, rectum, liver, prostate, kidney and skin (melanoma)\ were
not associated with cigarette smoking. There was no excess risk of Hodgkin's
lymphoma.. The following were clearly associated with smoking: lung (odds ratio
[OR] 12.1), bladder (OR 2.4), oesophagus (OR 2.4), stomach (OR 1.7), and pancreas
(OR 1.6). Population attributable risk percentages due to smoking were 90% for
lung, 53% for bladder, 54% for oesophagus, 35% for stomach, and 33% for
pancreas. CONCLUSIONS. Of the 21 types of cancer examined, lung, bladder,
oesophagus, stomach and pancreas were associated with smoking among men in
Montreal. Smoking likely accounts for a large proportion of cancers occurring at
these sites.
Transforming Growth Factor Beta (TGF1) and Insulin-like Growth Factor I (IGF-
1) Stimulate Collagen Synthesis In Rat Intestinal Smooth Muscle
TGF1 is a growth factor with immunomodulatory and fibrogenic effects in many
tissues including intestinal smooth muscle. Rats with peptidoglycan-polysaccharide
(PG-PS)-induced chronic enterocolitis have marked fibrosis in the distal ileum and
ceacum. The fibrogenic peptide IGF-1 is highly expressed in this model, but TGF-1
has not been studied. We ran a series of in vitro experiments to study the expression
of TGF- mRNA in PG-PS enterocolitis and the effect of TGF-1 with and without
IGF-1 on type α1 collagen synthesis in isolated rat intestinal smooth muscle cells.
Methods: PG-PS or control solution was injected intramurally into the caecum and
distal colon of Lewis rats. Intestinal smooth muscle cells were isolated from sacrificed
animals and cultured. Cells were washed to remove serum proteins and then exposed
in triplicate to IGF-1 (1.25-25 nM), TGF-1 (1-1000 pM) or both peptides together.
Procollagen α1 mRNA was detected by northern analysis of total cellular RNA and
type α1 collagen protein was evaluated by western immunoblot.
Results: A dose response increase of 2.4 + 0.6 fold (n=5; p=0.04) in TGF-1 mRNA
was observed in PG-PS treated intestinal cells compared with control tissue at 24 h,
with an increase detected at 50pM and maximal effect observed at 100pM. At 12 h,
250 pM TGF-1 stimulated a 2.1 + 0.4x increase in TGF-1 mRNA (n=4; p?0.05) and
a 4.0 + 1.6 fold increase in type α1 collagen protein. In parallel experiments, at 12 h
12.5 nM IGF-1 stimulated a 3.1x increase in IGF-1 mRNA. A similar increase in type
α1 collagen protein occurred after 12.5 nM IGF-1. There was no detectable synergy
between the peptides.
Conclusions: TGF-1 and IGF-1 stimulate collagen synthesis to a similar extent, but
TGF-1 is more potent than IGF-1 on a molar basis. Contrary to findings in other
systems, no synergy was detected. These data suggest that both TGF-1 and IGF-1
contribute to collagen synthesis during the response to PG-PS in rat intestinal smooth
muscle cells.
ACUTE CYSTITIS PATHWAY: A PHONE TRIAGE SUCCESS
Some physicians treat simple problems such as uncomplicated UTI in ambulatory clinics through
phone triage while others do not. The choice of and length of therapy also vary. In this study, we
evaluated the effectiveness of trained personnel using an acute cystitis pathway to establish the
diagnosis of uncomplicated UTI, to discuss the details with a physician, and to call in a low-cost,
effective prescription.
All patients calling our ambulatory clinic with symptoms suspicious of a UTI spoke with the triage
nurse. The nurse went through a specific checklist establishing a UTI diagnosis and excluding
complicating factors that might prevent treatment over the phone. As soon as possible, the results
were discussed with a physician. With physician endorsement, the nurse phoned the patient with
instructions, then called a prescription into the pharmacy. Forty-three patients were triaged; 3
were asked to be seen and one did not have a UTI. Of the 39 patients treated over the phone,
none had any complications. The time lapse from the patient’s initial call to the nurse’s call to the
pharmacy ranged from 30 minutes to 4 hours. We estimated the total savings in this trial at
$5,088, based on physician and clinic time, lost work time, and lowered prescription costs. Since we
see an average of 25 UTI’s/month, the potential savings in our clinic could reach $42,000/year. We
conclude that when an acute cystitis pathway is applied to low risk patients, with proper screening
tools and back up, there is a very significant savings. Based on this experience, we recommend a
phone triage trial for UTI treatments to other ambulatory clinics.
PENICILLIN ALLERGY: WHAT DO WE KNOW?
While 5-20% of the United States population report penicillin allergy, 80-
90% of those individuals are not truly allergic when assessed by skin testing.
Falsely reported penicillin allergy has far-reaching consequences including
antibiotic resistance, unnecessary or harmful avoidance of appropriate antibiotics,
and rising health care costs. There are significant deficits in knowledge of
penicillin allergy among community and academic physicians practicing internal
medicine and pediatrics. Improved physician knowledge is one way to combat
falsely reported penicillin allergy, but education on this topic is not currently a part
of most residency curricula.
The objective of this study was to assess resident physicians’ knowledge on
penicillin allergy and to determine whether a simple educational tool would
improve this knowledge. Participants were St. John Hospital & Medical Center
resident physicians in the departments of Family Practice, Internal Medicine,
Pediatrics, or Medicine-Pediatrics. Transitional residents, Emergency Department
residents, and medical students who were rotating in these departments were also
included. A one-hour session was scheduled during which the same ten-question
test was administered at the beginning (pre-test) and end (post-test) of the session.
After the pre-test, participants were given a thirty minute Power Point®
presentation on clinically relevant aspects of penicillin allergy.
The effect of the educational intervention was measured using a paired t-test
to compare the pre- and post-test scores, and the proportions of correct answers to
each question. Scores were compared by post-graduate year (PGY) level and by
department of origin.
Of 57 total participants, 54 completed both pre- and post-tests. 14 Family
Practice, 21 Internal Medicine, 2 Medicine-Pediatrics, 9 Pediatrics, 3 Transitional
or ER residents, and 8 medical students comprised the test population. Scores
improved significantly after the educational intervention [pre-test 54.8% 5.8%
(mean S.E); post-test 82.7% 5.5%; p = .007]. This benefit was seen among all
PGY levels and departments, except for medical students and Medicine-Pediatrics
residents (among the smallest in sample size). We conclude that a simple
educational presentation can improve resident’s knowledge of penicillin allergy in
the short term, and plan to test retention at specific intervals after this intervention.
Evidence-based Therapy Post-Coronary Artery Bypass Graft Surgery (CABG) and Potential Impact on Readmission While clinical trials have validated the use of aspirin (ASA), statins and smoking
cessation for secondary prevention after CABG, current adherence with these
therapies has not been studied. Furthermore, the cardioprotective value of beta-
blockers (BB) and ACE-I’s in pts undergoing CABG after AMI or with left
ventricular dysfunction (LVD), respectively, is uncertain. The purpose of this study
was to determine the utilization of these therapies in pts undergoing CABG and the
impact of readmission. Medical records of 113 consecutive CABG pts during Oct-
Nov, 1999 were reviewed for demographics, risk factors, medical history and
comorbidities. Therapies prescribed at discharge based on eligibility:
CABG PROFILE THERAPEUTIC INTERVENTIONS
(N) (N) (%) (readmits %)
CABG 113 ASPIRIN 96 85.0 82.0
CABG, AMI 63 BETA BLOCKER 46 73.0 57.0
CABG, LVEF <40 52 ACE-I 21 40.4 20.0
CABG, Smoking 20 Cessation Counseling 5 25.0 50.0
CABG, Hyperlipid 75 Statins 9 12.0 0.0
Eleven (9.1%) pts were readmitted within 6 months after discharge for cardiac
reasons. Using logistic regression, a model was constructed that predicted non-
readmission with a 93% specificity. Variables contributing to the probability of
readmission (in order of contribution) were: AMI 24 hours prior to surgery; no
statins at discharge; no smoking cessation education; AMI within 6 hours of
surgery; and not discharged on ACE-I (EF<40%) or BB (post MI). Therapeutic
adherence is suboptimal., and failure to prescribe these therapies may contribute to
cardiac readmission.
