Cryptosporidiosis Linked To
Swimming Pool
Fifty-one people w ho attended a
private sw im pool party on A ugust
30th at Sellw ood Pool in Southeast
Portland becam e ill w ith diarrhea,
officials at the M ultnom ah C ounty
H ealth D epartm ent announced to-
* day. The illness w as caused by the
parasite Cryptosporidium . N one o f
the individuals affected by this ill­
ness have suffered serious com plica­
tions. N one have been hospitalized,
and less than ten percent o f those
who becam e ill saw a doctor.
“C ryptosporidiosis is an illness
that usually involves diarrhea and is
o fte n a c c o m p a n ie d by sto m ac h
cram ps or vom iting," according to
Dr. Gary Oxm an, Multnomah C ounty
H ealth O fficer. "The vast majQrity
ofp eo p le recover in a few days w ith­
out any treatm ent, but people in­
fected w ith H IV can have prolonged
illness,” he said. There is no antibi­
o tic tre a tm e n t e ffe c tiv e ag a in st

Interview s w ith those w ho at­
tended the party show ed that sw im ­
m ing in the pool was the activity that

Cryptosporidium. “Exactly how this
pool got contam inated is unclear,"
said Dr. Paul Cieslak, Com municable
D ise ase M an ag er at the O regon
H ealth Division. "A round the United
States, there have been num erous
ou tb reak s o f d iarrhea caused by
sw im m ing in contam inated w ater in­
cluding sw im m ing pools, lakes and
rivers,” explained Dr. Cieslak. "The

Migraines
Migraine headaches have been tor­
m enting people since the tim e o f
Hippocrates. And torment is the cor­
rect descriptor, because migraines can
be debilitating. They can range along
a continuum from m ild headache and
no disability to excruciating pain and
com plete dysfunction. They can last
for hours or days; they can m ake you
nauseous, photophobic (sensitive to
light), and phonophobic (sensitive to
sound). And they have serious eco­
nomic consequences as well, leading
to the loss ofm illions o f w ork days per
year.
Headaches are not a m inor malady;
they are the seventh leading reason for
why people seek m edical assistance in
the US. M ore than 18 millions outpa­
tient visits per year are due to head­
ache. O f the different types o f head­
ache, w om en are m ore likely to de­
velop tension headaches or migraine
headaches, w hile m en are more likely
to experience cluster headaches.
M igraines are unfortunately too
com m on, affecting about one in 10
adults internationally, predominantly
women. The prevalence o f migraine
headaches in adults is about 6% in
men and 15 to 19% in women. These
figures vary with age, but the occur­
rence increases from puberty until age
40, and then declines more signifi­
cantly in older men.
There is a long standing debate as to
Sellw ood Pool on or around A ugust
30th and has developed diarrhea
should take particular care to wash
their hands with soap and w ater after
using the toilet to avoid spreading
the organism to others.
♦Everyone who uses public bath ­
ing areas should use good hygiene.
No one with diarrhea should go sw im ­
ming in a public pool or natural sw im ­
m ing area; children w ho are not toi­
let-trained should w ear sw im diapers
w hen they’re in the water.
♦Since people w ith HIV infection
and other im m une deficiencies m ay
get a more severe and prolonged
illness, they should contact their
m edical provider if they w ere ex ­
posed to the pool and develop severe
diarrhea. People w ith im m une d efi­
ciencies should be aw are that there is
some risk ofbecom ing ill from sw im ­
ming in public pools and natural bod­
ies o f water.* A nyone w ho has ques­
tions or is seeking additional infor­

the cause and nature o f migraine head­
aches. This debate focuses on whether
the origin o f migraines stems from a
vascular disturbance or a neurobio-
logical imbalance. However, there may
be an underlying mechanism involved
in the development o f migraine head­
aches that is characteristic o f both
theories. The role that serotonin plays
in the brain may be a link between the
neural and vascular systems. There­
fore, regulating the role o f serotonin
receptors may help prevent migraines
and leadtosignificanttherapeutic out­
comes.
Experience has shown that certain
foods can act as triggers in the onset o f
a migraine attack. Food culprits such
as chocolate, caffeine, cheese, fish,
wheat, nuts, tomatoes and alcohol (red
wines and champagne) are the most
well known triggers o f migraines. Cer­
tain food additives such as sodium
nitrite (found in processed meats and
hot dogs), M SG (Chinese foods), and
food colorings may also cause m i­
graines. Tyramine, a natural substance
which is found in foods that have been
fermented oraged, such as wine, Ched­
dar and blue cheese, may trigger mi­
graines.
Certain levels o f female hormones
may also trigger the onset o f or con­
tribute to the intensity o f a migraine.
The all too predictable headaches that
develop across the 3 to 5 days before
a w om an’s period are even referred to
as ‘menstrual migraines. ’ Women may
experience a greater number and more
severe migraines with pregnancy, lac­
tation, and in particular with meno­
pause. Estrogen replacement therapy
does not seen to alleviate these mi­
graines, and in some instances may
even exacerbate the condition.
The use o f computers has also con­
tributed to an increased incidence o f
migraine. O ne type, ‘cervicogenic mi­
graine,’ is precipitated by m uscle ten­
sion and spinal rigidity in the neck.
Staring at a com puter screen, holding
your head in one position for long
stretches, really tightens up the neck
and shoulder muscles, constricting the
nerves and blood supply to the neck
and head. T hat’s a prim e trigger for a
migraine.
There are natural rem edies that can
benefit a person susceptible to m i­
graines. Nutritional therapies that have
been shown to be helpful include V i­
tamin D and calcium (for menstrual
migraines, in particular); magnesium
(600 mg/day); and high dose ribofla­
vin (400 mg). Good hydration (drink­
ing enough fluids) is also important.
One o f the m ost effective natural
remedies for preventing migraines is
parthenolide, a com pound found in
the herb feverfew. It is used best as a
preventive, but can also help blunt a
migraine when it occurs. The key is in
g e ttin g th e e f f e c tiv e d o se o f
parthenolide, w hich is 250 m icro­
grams. Just using a feverfew supple­
ment may not work, since it doesn’t
c o n ta in a s ta n d a rd a m o u n t o f
parthenolide. A nother herbal aid for
migraine is ginger. G inger can settle
the stomach, and may reduce some
migraine symptoms after the fact.
Standard medical treatment for m i­
graines includes one or more o f the
following, depending upon whether
the strategy is to prevent a migraine
attack or if symptomatic relief is being
sought. Options include aspirin (low
dose for prevention), non steroidal
a n tiin fla m m a to rie s (N S A ID S ),
Sumatriptan, Beta blockers, calcium
channel blockers, and even hyperbaric
oxygen.
Although there has been no steadfast
cure or prevention o f migraines, exercise
and other natural remedies can be used
effectively to prevent or abort a migraine
attack. Chiropractic and massage may be
especially helpful for cervicogenic mi­
graine. Acupuncture, biofeedback, and
stress reduction have been proven effec­
tive in many cases. By the way, ifyou use
exercise to reduce the frequency or inten­
sity o f a migraine, don’t exercise during
an attack (as if you felt like it!).

effective barriers not only to HIV,
the virus that causes AID S, but also
to herpes sim plex, CM V, hepatitis B,
chlam ydia, and gonorrhea.3
O ut o f the laboratory, condom ef­
fectiveness declines w ith the intro­
duction o f the “hum an factor.” Be­
cause condom education has been
lacking, people do not use them well.
C ondom failure is m ore often due to
user failure than product failure.
U sers m ay fail to: 1) use a condom
w ith each act o f sexual intercourse,
2) put the condom on before any
genital contact occurs, or 3)com-
pletely unroll the condom .3 Using
drugs or alcohol can also impair judg­
m ent and proper condom use.4
To insure m axim um condom effi­
c a c y , th e fo llo w in g sh o u ld be
avoided: use o f oil-based lubricants
(petroleum jelly, shortening, lotions)
that w eaken latex; storing condom s
in d irect heat or sunlight; using
condom s in dam aged packages or
show ing obvious signs ofag e (brittle,
sticky or discolored).3
Absolutely. A lthough controversy
persists regarding w hether condom s
are an effective m eans o f preventing
hum an im m u n o d e fic ie n c y v iru s
(HIV) transm ission, condom s that
are readily available, effectively pro­
moted, and used correctly and con­
sistently, play an im portant public
health role in HIV prevention.
A bstinence or sexual intercourse
with a m utually faithful uninfected
partner are m ost effective in prevent­
ing HIV infection. H ow ever, in a
national surv ey o f adolescents, 63%
o f 14-21 year-olds reported engag­
ing in sexual intercourse. 1 Using
condom s can reduce the risk o f in­
fection o f sexually transm itted dis­
eases (STD s), including HIV, for
those people w ho are n o t abstinent.
No public health strategy can guar­
antee perfect protection. For instance,
the influenza vaccine is “o n ly ” 60 to
80% effective in preventing influ­
enza, but thousands o f deaths could
be prevented annually through the
w ider use o f this “ im perfect” vac-
cine.2
The real public health question is
not are condom s 100% effective, but
rather, how can w e m ore effectively
use condom s to help prevent the
spread o f disease.
W hy Do P eople N ot Use
Condoms?
M ainly because o f em otional re­
actions or m isperceptions. Results
from a telephone interview o f het­
erosexuals in 23 urban areas w ith a
high prevalence o f AID S found that
distrust associated w ith condom use
was m ore likely am ong m ales, A fri­
can-A m ericans, and the less edu­
cated.
O f the respondents, 54% believed
condom s m ight fail during inter­
course, 41% com plained they re­
Are Condoms Effective Barri­
ers?
Y es. In th e la b o ra to ry , latex
condom s are very effective at block­
ing transm ission o f HI V because the
pores in latex condom s are too small
to allow the passage o f the virus.
Condom s have been show n to be
Are Condoms Foolproof?
No. N either are seatbelts, helm ets,
vaccines, or people. But in the real
w orld w e drive to work, vaccinate
our children, and hope to get through
the day unscathed. N o disease pre­
vention strategy is ever perfect, and
all strategies,including abstinence,
depend on the skills and know ledge
o f the user.
A com prehensive HIV prevention
strategy uses m ultiple elem ents to
protect as m any people at risk o f HI V
infection as possible. A bstinence and
m utual m onogam y are a part o f that
strategy, as w ell as prom oting cor­
rect and consistent condom use.
In a study o f 245 heterosexual
couples w here one partner was HIV-
infected and the other w asn ’t, none
o f the 123 m ale or fem ale partners
w ho consistently used condom s be­
cam e infected. In contrast, 12 o f the
122 partners w ho either d id n ’t use
condom s or used them inconsistently
becam e infected. 13
