![]() No Pressure Please, by Dr. Dave Hepburn, M.D. After a patient has waited the customary 27 minutes in an exam room, preceded by the customary 52 minutes in the waiting room (hence the term “patient”), I am curious to see how they’ve bided their time in the exam room, especially when kids are involved. In a room replete with scientific discovery, kids are often found reflexing with the reflex hammer, jamming tongue depressors into various orifices their teddy bear didn’t realize he even had, or giving injections to a wailing sister. Mom, meanwhile, is deeply engrossed in the office’s latest TIME magazine (ie. the annexation of Alaska). But the kids’ single greatest source of entertainment is the blood pressure cuff, commonly known of course as the sphyngomanometer. They just love to get that thing wrapped around their mother’s forearm or their brother’s neck, pumping the wee bulb as vigorously as their meaty little paws can pump. Why is it that every MD’s office has a blood pressure cuff? A doctor may lack rubber gloves, matching socks or a medical degree, but he never lacks for a BP cuff. Is blood pressure all that important to doctors? Indeed it is. Also known as the silent killer, high blood pressure is so insidious that you may go to bed feeling perfectly perky but wake to discover you are dead. Are you one of the estimated 20 million North Americans who are hypertensive but unaware of it? Will you find out you were hypertensive after you’ve suffered your first stroke? Perhaps it will be a heart attack, heart failure or kidney failure that will alert you to the fact that you should’ve checked your BP every year. As high blood pressure percolates over the years it doesn’t turn your ears red, bulge out your eyes or cause any pain. Then suddenly, it hurts a lot. The most common cause of hypertension is called “essential hypertension”, meaning essentially we don’t know what causes it. We are, however, aware of some predisposing risk factors including:
The systolic pressure (the first number) is the pressure in your system when the pump (your heart) is fully contracted. The higher the systolic, the higher the risk of stroke. We like to see this number below 140, REGARDLESS OF AGE!! Some doctors do not treat the systolic pressure adequately in the elderly because they feel that the diastolic number is fine or even low. Whoops. The diastolic (second number) is the pressure in your system when the heart relaxes between beats. If it is too high then the risk of heart disease, kidney failure and stroke increases. Reducing diastolic pressure by as little as 5 points can mean a 40% reduction in stroke risk and a 50% reduction in heart failure. One problem in determining blood pressure is that the doctor’s office may not be the most appropriate place to take a reading. Whitecoat hypertension is a very common entity that can cause a BP to read 30 points higher in a doctor’s office than it would be at home. The patient finds himself in the office of the purveyor of pain, deliverer of doom and bearer of bad breath. The preceding patient has just left the office, screaming in pain and carrying an ear. The walls seem to yell, “Quick, get out of here!” This is hardly conducive to a normal pressure. I am therefore, a proponent of home monitors or community blood pressure programs. It’s much more effective, both fiscally and medically to put our effort into detecting and treating the blood pressure problem than trying to treat the consequences of neglect. Hypertension is the third leading cause of death worldwide, behind malnutrition and tobacco. So please, go and get your pressure taken somewhere. If you refuse, I’ll send the kids by to check you over. Storke of Luck, by Dr. Dave Hepburn, M.D. Walter, a wiry and robust 52 year old who bops through life as if his diet consists purely of Jolt, dill pickles and lemon juice, bounced out to the farmhouse, intent on whitewashing the cellar of the old place. Suddenly his head began to throb. He’d been plagued with headaches most of his
Know the five signs of a stroke! Pin these to your fridge, furniture or forehead.
Memorize these five symptoms. The mnemonic SDHWD helps, as in Send Dave Hepburn Wads of Dough. Repeat this mantra until it becomes a part of your very being. 15% of all strokes are a result of a brain artery bursting, most often as a result of high blood pressure. 85% of strokes are caused by the clogging of a brain artery, either through Big Mac plaque build up or from wee clots being shot off from an irregularly beating heart. If you can get a stroke victim to a proper stroke facility quickly and the clot is busted within 3 hours, about a third of these patients will recover with no disability. But the longer brain tissue is deprived of blood the more apt a patient is to end up writing newspaper columns. TIME IS BRAIN. For years not much could be done for stroke victims, but now many new and exciting treatment options exist. The greatest success is with the new clot busters including tPa and even ANCROD, the venom of the Malaysian pit viper. The snake simply latches onto your arm and injects its clot busting venom (just kidding, it actually latches onto your neck) A TIA (transient ischaemic attack) is a warning that you are about to have a stroke in the next few days or weeks. Lasting generally less than one hour, TIA’s may consist of any of the above five symptoms which by now you have memorized using the mnemonic I taught you (please repeat this SDHWD every time you head off to the bank). Get seen immediately, even if these symptoms clear up, as TIA’s are precursors to a stroke. Remember that dying at age 95 is OK, but living at age 55 after having been felled by a disabling stroke is rough. As for Walter Gretzky, though he has recovered, I note that he has been left with some serious memory deficits. Try as he might, he just can’t seem to recall that Wayne and I were separated at birth. Comb Free Living, by Dr. Dave Hepburn, M.D. “If you don’t have it, flaunt it.” Mr. Reynolds Mr. Reynolds was an unusual and frightening physics teacher. I was enrolled in his Hi School class, Unusual and Frightening Physics 101. To teach us the finer principles of physics he would bring in radioactive material for us to play with, boil plastic flamingos and even shoot off a gun (long before it was routine recess recreation.) But what made him even more unusual was that he was completely bald. Not a speck of hair on his 29-year-old head, eyelashes included. Made Yul Brenner look like a hippie. Compared to Mr.Reynolds, Kojak was a chia pet. Yoda. It was as though some experiment involving liquid nitrogen and Nair had gone wrong. Though I loved his class, I lost my composure one day when he brought in a bowling ball to demonstrate inertia and friction (think Senate). It sent me into a massive giggling spasm, the type where to keep from blurting out, you bite the inside of your cheek so hard you bleed. “What’s so funny, Hepburn?” “Well to be honest sir I was just picturing your eyeglasses on that ball and...” Later that day, while in detention, I finally screwed up the courage to ask, “Sir, how did you get to be so bald?” “Well” he responded with a sigh “I was a hairy guy once, then suddenly, “POOF” it was gone, in one week. The doctor called it Alopecia Areata Totalis. I call it the solar panel to my brain.” Alopecia areata One day out of the blue, your immune system, like your parents, might get sick and tired of your hairdo. It will attack the hair follicles and suddenly, over a period of one to two weeks, round bald patches will develop over the scalp. While this usually resolves spontaneously in three to six months, sometimes these bald patches coalesce, like that freaky mercurial cop in Terminator that just would not die. The patches can merge to the point that the entire head becomes bare, a condition called alopecia totalis. Sometimes, as in the case of Mr. Reynolds, the immune system takes out all body hair including eyelashes and facial hair. I recall a patient who had this same alopecia universalis at age 16 only to have all of her hair suddenly grow back at age 41! “Honey, do you remember where I put that Lady Gillette thing.” Male pattern baldness Roughly 50% of men will develop a “really wide part”, often decorated by three exceedingly long hairs stretched across the scalp for warmth. These Friar Tucks of hairdom usually hail from families with a genetic predisposition to baldness. Even women who are from families that have a history heavy in chrome domes may develop male pattern baldness. Like most of the world’s problems, we can blame this comb-free living on testosterone. Genetics determine how much testosterone will be converted to its nastier form, DHEAS, in hair follicles. Testosterone and hair follicles don’t get along. Testosterone, being tougher, wins. Men who are eunuchs or who have had their testicles removed for other reasons (see Clinton) STOP losing their hair! Hey, some guys hate being bald. While most of North America’s 80 million balding men just say no to drugs, rugs and plugs, the rest spend a slick seven billion dollars a year on hair loss treatment. One drug, finasteride, taken orally, will prevent testosterone from torturing hair follicles. Minoxidil lotion also helps to reseed the recede, though it must be taken continuously as hair loss resumes when the medication is stopped. Trichotillomania The deliberate compulsive pulling out of one’s own hair is a bizarre yet fairly common cause of unexplained bald spots. This may range from mild twisting and yanking of a few strands to a more severe grab and hauling out of massive clumps. Prior to age six it is primarily boys who engage in such behaviour, often perfecting this talent by practicing on their sister. After age six girl trichotillomaniacs outnumber boys 10:1. Treatment involves medications to treat compulsive behaviour disorders or else cutting off the hair completely which may seem harsh but hey, it beats what has to get cut off to treat male pattern baldness. If you are thinning or losing your hair for no apparent reason you should make sure your doctor does a blood test that includes: TSH, ANA, testosterone, DHEAS, iron, B12. All Dung With Dinner, by Dr. Dave Hepburn, M.D. Not having a TV in my family has its pros and cons. While we spend less mind-numbing and obesity-inducing time with our noses glued to some senseless sitcom spew, there are those days when we'd be thrilled to watch even the test pattern on channel 2. TV shows become a treat rather than a habit and so, whenever we have the occasion to watch TV, we sit spellbound, staring at commercials with slack-jawed intent as if we were watching the Queen of England belly dancing for a herd of Klingons. And so it was that I found myself in a hotel room with my son watching with utter fascination a documentary on badgers. Were you aware, for example, that these resourceful excavators can sense where underground dungballs are hidden? What's a dungball? Well if you'd watch more TV you'd know. As any amateur dung beetleologist knows, dung beetles zip about collecting great wads of dung which they then fashion into a large croquet-sized ball. As if rolling up a snowman, these dung beetles don wee scarves and go outside to frolic in the dung, making assorted dung angels, dung forts and dungballs. But instead of sticking carrots or coal in the ball, they lay their larvae in the dungball, assuming they will be safe from any self-respecting animal with half a nose. They didn't count on the disgusting badger. As we watched, the TV's larva-cam caught a badger clawing open a large ball of dung and then sticking its tongue into the center of it with great relish. As it slurped up a vile mix of large juicy larva and dung, I found it necessary to put down my pizza. In fact, I closed the box. How could anything be interested in digging through such a nasty ball of poop? Yet as physicians, or at least lab techs, we relish the opportunity to do much the same, minus the tongue and the larvae. The most sought after information in a stool specimen is the presence of hidden blood. Last year 60,000 North Americans died of a largely preventable disease, colorectal cancer (CRC). Another 150,000 got the news that they have contracted this second deadliest of all cancers, lung cancer being the first. If you are a non-smoker, CRC is the cancer most likely to do you in. The good news is that CRC is generally a slow-growing beast that gives hints that it is about to turn nasty by leaking very small amounts of blood into the stool. CRC begins its life as an easily removable polyp. While most colonic polyps are small and pose no threat, larger polyps, which take five to ten years to grow, are precursors to cancer. For this reason, every man, woman and child over age 50 should have an annual Fecal Occult Blood Test (FOBT). See a doctor who will give you three test cards to take home. Eat a high fibre diet for two days, avoiding broccoli, cauliflower, Vitamin C and red meat, all of which can affect the test reagents. On three separate days take a small stick and (retch, gag) apply stool to these cards, then fold them back up. These cards look like scratch and win cards but please advise the kids or any lotto players in the house that these would become scratch and lose cards should they open the card and enthusiastically rub. Discard the stick far away from coffee stir sticks. Return the card lovingly back to your doctor accompanied by a card of appreciation for what he has go through just to insure your good health. Alternatively, to the chagrin of the Cliff Clavins of the world, you can mail the sample in, hoping that the mailman doesn't have a pet badger accompany him on his route. Through the miracle of modern medical magic the doctor can instantly detect the presence of blood in the stool. While blood does not always mean cancer, it does mean that further investigation, in the form of a colonoscopy, is warranted. As screening tests go, FOBT has proven to save lives through early detection of a cancer that is usually not bothersome to its victim until it has spread ominously beyond the bowel wall. Since 1984 death by CRC has decreased by 2% per year due to enhanced screening and better mail service. So please, screen yourself. Though it may sound less than palatable,
go and see your doctor and have this simple test done every year. In
addition to keeping us all humble it may save your life. Please don't
make us badger you. Top 5 Health Benefits of Travel, by Dr. Dave Hepburn, M.D. “Travel is fatal to prejudice, bigotry, and narrow-mindedness. Broad, wholesome, charitable views of men and things cannot be acquired by vegetating in one little corner of the earth all one's lifetime.” The problem with we North Americans is the two week vacation, known to the rest of the world as the too weak vacation. While Australians enjoy taking a six month walkabout and wanderlust Germans seem to be on a never ending hinterlands hike, we would rather work ourselves into the grave and then wonder why we never got out and experienced wonder. When I am on my doctorly death bed, looking back over my life I won’t be relishing the time spent with my finger in unmentionable places but rather my time spent with my finger pointing at unforgettable places. I won’t remember lying on the couch watching hour after hour of The View but I will remember watching the view hour after hour. Q: “Dr Dave, are those who take vacations healthier?” 1. Men at high risk for coronary heart disease who take frequent annual vacations are 21% less likely to die of any cause and 32% less likely to die of coronary heart disease.
2. Lose weight!
3. Relax!
4. Blood pressure, heart rate, and levels of epinephrine – a stress hormone – decline on vacations.
4. At least 4 out of 10 travelers feel more romantic on vacation.

The prostate and the breast, both capable of harboring hormone-sensitive cancers, possess some intriguing similarities.
Bleebieology or What is Dermatology?, by: Dr. Dave Hepburn, M.D.
If you could be a doctor for a day, what kind of doctor would you be? Surgeon, GP, cardiologist, George Clooney, Dr. Hook? What if you had to decide on the type of doctoring you would malpractice every day for the rest of your life? Such a decision is one that all medical students must make as they edge closer to actually obtaining their MD (Masters of Deception). Those who don't mind spending a total of 47 seconds per week with their family choose surgery. Those who feel sleep is a waste of time go into obstetrics.
Yet abdominal pain and rashes tend to be the toughest problems for most GP's to solve. A patient can often be panic stricken about an intense rash, one that I might not recognize. Adding, "Wow, I have never seen one that colour before, at least not on a live patient!" tends to convert their panic into frenzied terror. So I call up a helpful dermatologist, the nicest of all specialists (something to do with eight hours sleep), who calmly solves the carcass conundrum. They are expert rashologists, toenailologists and bleebieologists. Knowing about a few common bleebies may save you unnecessary panic. So, while I close my eyes, remove all of your clothes, get out a mirror and check for: Seborrheic Keratosis Skin Tags Basal Cell Cancer But if at all in doubt about a bleebie or any mysterious lumps or bumps be sure to have it checked out by a professional such as George Clooney. He can be reached at www.drdavelookalike.com.
Macular Degeneration or Degenerate Eye Problems, by: Dr. Dave Hepburn, M.D. I caught the Perseid meteor showers last summer, or at least I watched them, or at least I tried to. August's celestial showcase, performed on the northeast stage of heaven's amphitheatre, is an exercise in aggravation to many of us who would actually like to see this shooting star spectacle. Lying flat on the long grass with my young son, while dew, dirt and various vile invertebrates violated my ear canals, he would point quickly
To 10% of those older than 65 years of age and to 30% of those beyond 75, peripheral vision may be all that actually works anymore. The macula, a small area in the back of the eye (the retina) responsible for central vision, can degenerate all too easily. In fact, far too many of the Edsel/Eisenhower/Elvis generation are now in a general state of de-generation. Bones, joints, memory, muscles, hearing, vision and other organs of various size and function all begin to shrivel as we begin our free fall into the world of senescence, one we all too often have not prepared properly for. Even the invincible Britney generation needs to prepare now to eventually join the degenerate generation. Macular Degeneration (MD), (also known as "smackular” degeneration given the many times that foreheads become intimately acquainted with telephone poles, baseballs and oncoming wheelchairs) causes loss of "straight ahead” vision in both eyes. This makes simple tasks like reading, driving and ogling intolerable. The macula can be wrecked in two ways. It may be invaded by a horde of leaky blood vessels that destroy the macula, the so-called "wet” macular degeneration. Or, in "dry” degeneration, which accounts for 90% of MD, the macula may just start to shrivel and break down, slowly causing vision to blur and dark patches to emerge in the middle of a sentence. For example, if this health column were juxtaposed to a gardening column there might be large gaps in the center of your vision, leading to sentences like: to prevent nose bleeds · · · · · · · · don't pick too early and always check for beetles the eye surgeon might· · · · · · · · · · · · · · · · use a large-toothed 22 horsepower rototiller if not circumcised, a boy might discover · · · · · · · · an aggressive Venus fly trap side effects include · · · · · · · · spreading a large amount of manure and worms about the bed Wet MD causes a more profound blindness and is actually responsible for 80% of legally blind eyes. But caught early, there is a chance that thermal laser treatment, and hours of fervent prayer may be able to slow wet destruction of the macula. Macular degeneration may not always render its victims blind but it might reduce them from fully sighted to partially sighted. Still, loss of central vision can lead to loss of driver's license, loss of autonomy and loss of joie de vive. Although sun exposure, high blood pressure and lack of Zinc have all been named as suspects as a possible cause of MD, the only proven risk factor is our old friend, smoking. After smoke gets in your eyes, don't it make your brown eyes blue.
But most importantly, remember that you will invariably go blind unless you ask your doctor to ........ clip your begonias each fall.

Nuts in your diet or Health benefits of Brazil Nuts, Almonds, Cashews, Walnuts, Filberts Peanuts etc. for reducing cholesterol, cardiovascular disease, prostate cancer, diabetes.... , by: Dr. Dave Hepburn, M.D. "...Nut snackers actually eat less, lose weight and have less diabetes." On rare occasions, when I find that my pantry is low on the essential food groups such as Cocoa Puffs, Snickers and Dr.Pepper, I go grocery shopping. Not one to linger too long in the tofu and wheat germ aisle I slink over to the bulk food section, salivating fondly over these massive barrels of massive calories. When it comes to the cases of nuts, admittedly, I am a bit of a nutcase. I scoop up a large mixture of nuts, flick aside the ugly Brazil nuts, flick in a few more cashews and make for my pantry.
ALMONDS CASHEWS WALNUTS PISTACHIOS PEANUTS So as I sit here with my bag of filberts and salt, my everlasting-prostate sons are fully sated. While a corn doodle or other empty carb snack leaves the snacker hungry again in 30 minutes, a handful of nuts satisfies hunger pangs for several hours. Nut snackers actually eat less, lose weight and have less diabetes. Satisfying, fat, tasty and highly nut----ricious.

"SMELL YOU LATER!" The Power of the Sense of Smell, by: Dr. Dave Hepburn My grandfather's name was Dah. His real name, I'm told, was George, but to his grandkids he was good ol' Dah. As a wee lad I would spend hours sitting on Dah's lap, watching the
Thirty years after his passing I received an unexpected phone call. "Hi, my name is Bugsy and I fought alongside your grandfather George in Italy.” "You knew Dah?” I exclaimed, thrilled at being reminded of my childhood pal. As Bugsy went on to relate some of Dah's legendary military feats, which usually featured greased pigs, five aces or stolen jeeps, I began to notice a strange odor at my desk, stranger than normal. I glared at the dog who glared back with a stupid yet innocent grin on his mug, but it wasn't him. Suddenly this strange yet familiar smell twanged the memory cells of my brain. It was Dah's cigar. So clearly could I smell that smoke that I had to look around the room twice to insure that no such cigar was smoldering. Smelling a man dead thirty years may seem a tad Beetlejuicy and perverse, but in the part of my mind responsible for smell he was very much fresh and alive. Such is the power of the sense of smell.
At the roof of our nose, in a happy little bone called the cribriform plate, sits the olfactory bulb, an organ that is lined by kazillions of glomeruli. These amazing specific smell files can detect, differentiate and process 10,000 different smells. While taste buds have four basic tastes: salty, sweet, sour and Snickers, it is the sense of smell that allows us to identify exactly what it is that we have just placed in our mouth. When an odor, nice or nasty, wafts into our nostrils, past assorted hairs, chalk and peas, the glomeruli processes the odor, packs up the information and fires it along the olfactory nerve to some place in the brain right next to the It-Wasn't-Me! denial center. Anosmia refers to the complete loss of smell. The commonest causes of anosmia include:
Age Factors & Smell Half of those over age 60 have some olfactory dysfunction not necessarily related to any disease, unless you term aging as a disease. As we age, our sense of smell joins the vision and hearing in a gradual decline. Rather than young vibrant cells working hard in the olfactory center, old factory workers now go on strike. Smoking helps to wear down the old factory workers even further. A lack of smell is associated with increased depression and a lower quality of life. Thus it can be concluded that smoking contributes to depression. Astonishingly, loss of smell can also be an early marker for certain neurodegenerative diseases such as Parkinsons, Alzheimers and even Multiple Sclerosis. In fact, anosmia may be the first symptom to signal the onset of these diseases. As for you Dah, thanks for knocking some "sense” back into me. Smell ya' later.
