The most talked-about “super bug” is a subtype of the bacteria Staphylococcus aureus called MRSA (methicillin-resistant Staphylococcus aureus), a highly antibiotic resistant strain with the ability to produce toxins to weaken its host. This bacteria has killed more people this past year than the HIV virus, and estimates have reported that “staph infections” have cost hospitals alone 14.5 billion dollars in 2003. Aside from affecting skin, staph can also cause deeper tissue, bone, joint, heart valve, lung, and bloodstream infections which can be deadly in both ill and healthy people.

MRSA used to be mainly acquired from hospitals. In recent years, there has been an offshoot of hospital-associated MRSA called community-associated MRSA (ca-MRSA). Ca-MRSA, representing about 12% of MRSA infections, is often heartier due to rapid spread and adaptability, and may even have the ability to counter some of our bodies’ immune defenses.

Transmission is through direct skin to skin contact, sneezing, and touching objects already contaminated with the staph bacteria. 20-30% of the normal adult population has staph colonized in their noses, belly buttons and other body parts. This means that the bacteria are present without causing disease except in cases of skin breakdown or immune system compromise (such as with Diabetes, HIV, or Cancer/chemotherapy). Staph is more prevalent in situations of close contact as in daycares, adult homes, shelters, hospitals, military barracks, and certain sports. IV drug users and those with chronic indwelling catheters, recent surgical wounds or long hospitalizations have a higher incidence of staph infections, and of course, there are higher rates of spread within families.

What do staph infections look like on the skin? First, they can occur almost anywhere on the body. Patients often come to me with recurring “red hair bumps” or “pus-bumps” or deeper “boils” that either won’t go away or seemingly do resolve but then keep coming back. Other patients say that they have “spider bites” that do not itch but become filled w/ pus, hurt, become red and swollen. When asked, they often never actually see the “bugs” that bite them. Even if the rash did start off due to insect bites, that skin can get secondarily infected from scratching. If staph gets into deeper tissue, bones, lungs, heart, or the bloodstream, it can cause fevers, chills, body pain, tissue damage, and internal organ failure in the most severe form.

Treatment starts with first speaking with your healthcare provider. If Staph aureus is suspected, the provider should do a bacterial culture of the affected tissue and/or nose, lance and drain any abscess, and place the patient on antibiotics if the patient has symptoms such as pain, pus, fevers, or expansion of the infection. Systemic antibiotics should especially be given if the patient has other immune suppressing health issues as discussed above. If there is a high suspicion for MRSA, two appropriate antibiotics should be started at once and kept on it for the appropriate length of time. It is very important to take the full course of antibiotics that the doctor prescribes.

An ounce of soap is worth a pound of antibiotics. Hand washing, hand washing, and more hand washing is the key to prevent spread of staph. 30 seconds of plain soap and water or using the alcohol preparations until hands are dry are effective to eradicate the germs without causing resistance. Also, cover open wounds and do not share personal hygiene items. Avoid unnecessary antibiotic use (as when having viral illnesses), and if already on oral antibiotics, take them as instructed for the full time prescribed.

To find out more, go to the CDC website: www.cdc.gov. Please see your healthcare provider if you suspect you may have a staphylococcus infection.

Now that the summer months are almost here, the unlucky amongst us should learn to recognize and avoid those infamous plants that cause us to suffer from skin rashes, swelling, itching, and sometimes severe allergy or anaphylaxis upon contact with the plant. The mechanisms of rash development is actually from a complex immunological reaction that our bodies develop against the allergen, a true allergy called Allergic Contact Dermatitis.

Everyone has heard of Poison Ivy, Oak, and Sumac, but not everyone knows what these plants look like or methods of preventing contact with the allergen. 70 to 85% of the population has been sensitized and thus can potentially get the rash, with it actually affecting about up to 50 million Americans. In Texas, it is mainly Poison Ivy that causes Allergic Contact Dermatitis.

• Poison Ivy is a weed with three shiny green leaves and a reddish stem, with either small green flowers or green-white berries. The leaves can have either smooth or serrated edges. It grows as bushes, plants, or vines. It is found throughout the US except in the Southwest, Alaska, and Hawaii.

• Poison Oak also has the same three-leafed structure, but grows as a shrub on the West Coast but can be found in the Eastern US as well (rarer in Texas).

• Poison Sumac is a woody shrub with each stem having 7-13 leaves arranged in pairs. It mainly grows in standing water in the peat bogs/swamps of the Northeast, Midwest, and Southeast.

The common denominator of these plants, all part of the Toxicodendron Genus of plants, is an allergen called urushiol, an oily resin. Sensitized people will get the rash within 12-48 hours after contact, and the rash can persist for 3 weeks. The rash is uncommon in children less than 7 years old, and rare in infants, due to undeveloped immune systems.

While the rash is not “contagious” in the strictest sense from one person to the next, the oily resin adheres to everything that comes in contact with the plant. Thus, these items , including freshly contaminated skin, pets (animals do not get the rash), clothing, and tools, must be washed or that allergen can continue to cause rashes. If left on inanimate objects, the resin can be allergenic for years. Even smoke from these burning plants can transmit the resin and irritate eyes, oral, and nasal passages.

Scratching the blisters does not spread the rash; the appearance that the rash is “spreading” is due to your skin responding at different rates from the initial contact with the plant. Washing affected skin with isopropyl alcohol and/or soap and water can only prevent the allergy if it is done within 10 minutes after contact with the resin. For those who are extremely sensitive, there is a product called “Ivy-Block” that can be placed on the skin prior to anticipated contact with the plant. This topical product contains 5% bentoquatam, a compound that prevents penetration of the resin into the skin.

Most people get mild skin reactions treatable with over-the-counter medications such as oral antihistamines like Benadryl®, calamine lotion, hydrocortisone cream, and cool soaks. People should see their physicians if the rash is severe or widespread, if it affects eyes, nose, mouth, or genitalia, if the rash gets infected, if you get a fever of 100°F or greater, or if the rash does not improve after 3 weeks. These patients may need very strong topical preparations, oral prednisone, and/or antibiotics.

Oh, we shouldn’t have…. What exactly happens to our bodies after we just consumed the largest holiday meal of the year? Those excess calories from carbohydrates, proteins, and fats that are not used for daily body metabolic activity ultimately get converted to body fat – eek. But for some people, the skin can show food consumption in other ways aside from just showing our love handles.

First, excess lipid or fats can deposit in our skin and other organs, but not in the way we ordinarily think. There are some genetic and metabolic syndromes and even medications that cause very high levels of cholesterol circulating in our system. These cholesterol levels or triglycerides can deposit right in our upper layers of skin causing distinctly yellow-orange small pea-sized bumps in certain parts of our body such as near the eyelids, palms, knees, elbows, arms, and legs. We call these skin lesions xanthelasma if involving the eyelids and xanthomas if involving the rest of the body skin. Though often reversible by diet and cholesterol -lowering medication, some of these skin lesions can sometimes be permanent.

Next, we always think of gout as being a disease of older men, a painful condition traditionally causing large painful skin nodules on the big toes or ear cartilage or elbows, knees, and wrists. Rich, meaty foods, such as red meats and certain types of fish and seafood, and alcohol (beer, liquors) have high purine contents. If you consume these foods regularly and drink over two alcoholic beverages a day, or if you are on certain medications, the uric acid levels get high enough to crystallize out of the blood circulation into distant areas of our body, causing painful skin nodules with arthritis and kidney stones. The treatment is taking medication to lower uric acid levels and for pain control. Lifestyle changes include avoiding rich foods and alcohol and consuming more dairy products, complex carbohydrates, and fluids. Steady weight loss will help as well.

Salt lovers beware. Those who consumed too much salt probably felt it the next morning from tight clothing and rings. Unfortunately, those with heart failure cannot handle the extra fluid volume from salt and subsequent water retention. One skin manifestation from this is leg swelling. Long-standing leg swelling can make the skin of the lower legs itchy, reddish-purplish, and eventually hard. For those with heart failure, a low 2 gram sodium diet has to be followed.

Moderation is the key for everything including alcohol consumption. Chronic alcohol use can cause liver damage with end-stage cirrhosis as its worst outcome. Skin signs of alcohol-induced liver disease include yellowing of the skin and eyes, called jaundice, from excess bilirubin levels; the abdominal blood vessels are more pronounced on top of a swollen, fluid-overloaded belly; there are little smaller red superficial blood vessels that appear on the upper body called spider angioma; there is increased skin bruising and/or itching; and there are even nail changes. The only treatment for end-stage cirrhosis is surgery or liver transplant.

Lastly, there are some people who have severe gluten sensitivity, causing a gastrointestinal disease called Celiac Disease. These people are not able to tolerate wheat, rye, barley, and even some medications and food additives in their diets. A small subset of these patients get a skin rash called dermatitis herpetiformis consisting of broken itchy red blisters on the elbows and knees and lower back. A strict gluten-free diet is essential to treat both the skin and gastrointestinal condition.

With all the news about our “super-bug” adversaries from staph infections to salmonella, e.coli and even influenza outbreaks, the medical community is hyper-vigilant to control infectious disease. We are living longer lives thanks to antibiotics, immunizations, proper medical and food preparation sanitary techniques, and earlier detection and prevention of disease. Our home and work environments are cleaner than ever – we have air and water purification systems, high-tech vacuums to remove dust and dander, and we even keep our pets dirt- and disease-free.

However, there may be a downside to our very “clean” society. The Hygiene Hypothesis is a theory amongst immunologists that has been gaining popularity in the last twenty years. Humans have coexisted with microbes throughout our existence, and we now are aware that we depend on disease to stimulate our proper immune function.

In our current industrialized society, as our children get less exposed to infectious agents and succumb less to the usual childhood diseases, they may be more susceptible to developing allergic disorders such as seasonal allergies, asthma, and atopic dermatitis. In some parts of the country, in particular in large urban centers, there is an epidemic of asthma and other allergic disorders. There has also been a rise of autoimmune diseases such as inflammatory bowel disease, multiple sclerosis, and type I diabetes in our “developed” society. Interestingly, “third world countries” in Africa and Asia have an extremely low rate of allergy and autoimmune diseases, but of course have a very high infectious disease exposure rate.

The hygiene hypothesis has changed the way we think about “good” and “bad” disease. Dirt and disease most likely are necessary evils, as every subsequent allergen exposure and infection helps harden our immune system to prepare for the next latest and greatest attack. Maybe it is not the infectious agent that we need to worry about but the lack of exposure to infectious agents.

While no one wants to suffer through colds or gastrointestinal ailments, if the alternative were to have a chronic debilitating ailment such as asthma or multiple sclerosis, the choice may be a simple one .

For future treatment, scientists are working on using parasites and developing normal gut flora to help stimulate immune function.

While no one is suggesting to get rid of antibiotics and vaccines and basic cleanliness techniques, we have to be aware of the consequences of our modern ultra-clean lifestyles. We do not necessarily have to go place our children in the mud everyday to get their daily quota of dirt exposure, but we should let kids be kids and allow them to play outside with other children and not worry too much about them getting exposed to dirt and germs. Also, we must depend on our doctors to decide whether or not antibiotics are warranted in times of illness. Overuse of antibiotics can of course cause the development of antibiotic-resistance and thus the rise of “super-bugs.” It can also cause changes in our normal gut flora and secondarily prevent maturing immune systems from developing and functioning properly.

The success of fertility procedures has allowed couples, both young and older, to experience the miracle of life when nature otherwise would not allow for it. The availability of these procedures now also secondarily helps us plan our families, in balancing it with careers, household, and other social pressures. However, is there an ethical and biologic limit in terms of how far we should go? Currently, it is a personal and medical decision to be made depending on the state, the doctor, and the circumstances of the individual(s) in question.

Our modern lifestyles are causing us to be out of sync with our biological lifecycles. Despite our emphasis on pro-youth, anti-aging prevention and medical treatments, our bodies still keep track of chronologic time. As women especially spend more time in education, careers, and social development (there has been a fourfold increase since the 1970s in the number of women after age 30 having their first child), our years of prime fertility often slip behind the wayside. When we are emotionally, socially, and economically ready to start families, it can be a shock when our bodies fail to cooperate.

Female fertility is at its peak around the ages of 19-24 years. After the age of 30, our fecundity drops, especially dramatic after age 35, with a concomitant rise in the rate of miscarriages and chromosomal abnormalities. Though infertility issues are half the time caused by male factors, it is the female that is the biologic bottleneck since we are capable of conceiving only 12 times a year for about 30+ years of our lives. Thus, only about 400 of our original one million eggs that we have at birth are ever potentially “usable” due to human female ovulatory cycles. The quantity and quality of those eggs also diminishes greatly after age 30, with about 1,000 eggs lost per month.

At any given time, 11million of 90 million US couples are trying to conceive, with a success rate of 20% per month. It will take the average fertile couple 5-6 months to conceive before success. 1 out of ten couples will experience infertility as defined as failure to conceive after 12 months of active efforts.

Doctors often start diagnostic testing if the female is over 30 years old, if there is an abnormal medical, reproductive gynecological history such as repeated miscarriages, or if the male undergoes testing and has a low sperm count.

Infertility treatment options currently include medications and medications in conjunction with variations of the following procedures (Assisted Reproductive Technology). The most common are:
• Glucophage to boost ovulation if insulin-resistance is a suspected factor
• Clomiphene therapy to stimulate mature egg production
• Gonadotropin therapy (often follicle- +/- leutenizing stimulating hormone; or gonadotropin releasing hormone) to stimulate increased numbers of eggs produced per cycle
• Human Chorionic Gonadotropin to stimulate release of eggs from follicles
• intrauterine insemination (IUI, aka artificial insemination) where washed sperm is injected into the uterus around the time of ovulation
• In-Vitro Fertilization (IVF) – harvesting the egg and inseminating it in a petri-dish and placing the zygote back in the uterus

The frustrations of infertility treatment aside from cost (often in the tens of thousands of dollars), is that these tests can take many precious months of time, and there can be a significant failure rate. They are also not without their side effects including the probability of multiple births or enlarged ovaries.

Talk to your Ob-Gyn or Urologist if you are concerned about what is the right treatment course. Aside from medical intervention, both the male and female should avoid tobacco, excess alcohol, and perhaps excess caffeine, as well as maintain a normal weight by good nutrition and moderate exercise…and the hardest advice of all to follow: Avoid Stress.

It feels like winter, even in Austin. Though a relief from the high heat and humidity of the rest of the year, how can we protect ourselves from the drying effects of this season to keep our hair, skin, and nails healthy?

During the cool, low-humidity weather, we lose more moisture to the outside air just from diffusion and evaporation through moisture and temperature gradients. This loss of moisture is called transepidermal water loss (TEWL) and is a measure of the function of our skin barrier. Aside from temperature and humidity changes, aging, certain medications and genetic conditions can speed up our TEWL. Luckily, a few basic easy tricks can lock that moisture back in to prevent our skin, hair, and nails from looking and feeling cracked, rough, and lackluster.

The outermost layer of our skin and our entire visible portion of our hair and nail units are non-living. For skin, the “bricks” are made of a dead skin cells made mainly of a protein called keratin. The “mortar” of these keratin sheets is composed of lipids – ceramides, cholesterol, free fatty acids, etc – with complex chemical bonds with other proteins. Thus, our skin, even the outside “dead” layer, is composed of a complex interlocking of lipids, keratin, and other organic and inorganic chemicals to maintain proper water content, pH balance, and function.

Skin keeps our body temperature and water/salt homeostasis in check. Great skin also makes us look healthy and vital and younger. When skin dries, most people start to feel itchy or have pain from cracks in skin; hair can be unmanageable with much static, and nails will crack from being brittle. We are not talking life-and-death medical issues here, but for those who’ve ever had bad dry skin itching, it can keep someone up many hours in the night from the discomfort.

The treatment is moisturizing right? Yes…but which one to choose? There are moisturizers, emollients, humectants, occlusive agents or greases, and lubricants. There are also lotions, creams, ointments, oils, etc. The former set either keep moisture locked in or attract water back into the layers of skin and nails to keep it supple. The latter set has to do with the consistency of the topical and how well they can hydrate, cool, and/or deliver medication to the skin.

You do not have to spend much to get adequate moisturizing. Home remedies can include placing olive oil or safflower oil on skin on for multiple nights. But if you don’t want to smell like cooking oil, choose something that you won’t mind using consistently. For instance, choose a moisturizer that is light in the summer such as a lotion and heavier in the winter such as a cream. As Dermatologists, we recommend heavier creams or ointments for those with very dry skin or eczema (dry, rashy skin).

Also, Dermatologists prefer patients to use fragrance-free products because the fragrance, though it smells great, can often be a skin sensitizer. “Unscented” just means the manufacturer used a second fragrance to mask another fragrance, so beware.

Moisturizing is more than half the battle, but what about the rest? Use a mild, moisturizing fragrance-free soap or cleanser and take shorter, lukewarm water showers or baths. Long, hot showers can actually promote water loss from skin. Gently pat dry your skin with a soft towel. Apply moisturizer to skin and nails immediately (within three minutes) after bathing and occasionally throughout the day. Avoid wool or harsh fiber clothing directly on skin as well. Use fragrance free detergents, without fabric softeners if possible, as the latter often have strong chemicals. Lastly, consider purchasing a humidifier if your environment tends to be dry (this will also decrease hair static).

As for drinking lots of water to keep your skin hydrated, the medical consensus is mixed. Water can improve internal organ function but that consumed water may not necessarily be transmitted to skin cells unless the person is extremely dehydrated. But it can’t hurt either drinking that daily 64 oz of water in healthy people.

We all wish for a good life with happiness, but when our health, or that of a friend or family member, is compromised, it consumes us. Perhaps the most dreaded threat is the big “C.” For 2008, it is predicted that there will be over 1.44 million people diagnosed with cancer and more than 560,000 cancer deaths. Unfortunately, everyone is vulnerable.

Cancer occurs when one of our normal cells has a DNA mutation that causes a rapid and uncontrolled division. This malfunctioning cell population, no longer recognizing “self,” competes with our normal tissue for blood supply and nutrients. These cancer cells may then invade other parts of our body, or metastasize, causing organ failure and possible death if left untreated.

Because of senescence, or biological aging, our cells lose the ability to maintain cellular repair and immune surveillance. That can be one reason why certain cancers are almost expected once a certain age is reached, such as prostate cancer in older men.

While cannot control genetics and aging, we can control our environmental and lifestyle choices, which is sometimes more than half the battle. Specifically, tobacco, alcohol, dietary, occupational, and physical activities and even our reproductive and beauty habits affect our cancer risk. There are things we can do in our everyday lives that are easy and still allow us some fun!

The first step starts with your doctor. There are cancer screening guidelines according to age, past medical and family history, and perhaps even past chemical or viral exposure that your general practitioner can address. For example, women should get a pap smear by age 21 or earlier and a screening mammogram by age 40 or earlier if strong risk factors. Both genders should get a screening colonoscopy by age 50 or earlier. Lung, prostate, skin, and ovarian cancer screenings are discretionary at this time. We do know, however, that cancer screenings can prevent up to 35% of cancer deaths.

Simple daily lifestyle changes:

1. A healthy diet is important. So far, there has been mainly indirect evidence for healthy diets decreasing cancer risk, but the point is that it can’t hurt. “Power foods” loaded with antioxidants, fiber, and vitamins include fruits, veggies, green tea, whole-grains, fish with omega-3-fatty acids, yogurt, nuts, soy, etc.

2. Stop smoking. First- and second-hand smoking increases our risk of virtually every cancer. Smoking also negatively affects every major organ system in our body.

3. Limit alcohol consumption. Modest alcohol intake, especially red wine, can be heart-healthy. But excess alcohol consumption can increase risk of breast, oral, esophageal, and perhaps liver cancer.

4. Exercising 30 minutes a day, at least 5 days a week is recommended with the approval of your physician.

5. There is a new HPV vaccine for females age 9-26 years which may prevent cervical cancer. Most importantly, preventing transmission of this STD is essential.

6. Get the right amount of sun exposure. Unless you are getting adequate Vitamin D through diet, 5-30 minutes of natural sunlight twice a week (more if you are darker skinned or elderly), should provide the amount you need. Vitamin D as a hormone may protect against breast, colon, prostate, ovarian, and ironically, even some skin cancers! But excess UV exposure can increase our risk for skin cancers including the dreaded melanoma.

7. Women should do monthly breast self-exams and men testicular self-exams. Both genders, especially with a previous history of skin cancer, should do monthly skin self-checks.

8. Wear your sunscreen and reapply often. It can prevent squamous cell carcinoma of the skin and hopefully, melanoma, without greatly affecting Vitamin D synthesis.

9. Brush and floss at least daily and see your dentist regularly. One recent study suggests gum disease may be associated with up to 14% higher cancer rate.

This article is in tribute to October as breast cancer awareness month and is dedicated to the 182,000 women and 2000 men newly diagnosed with breast cancer and to the 40,000 who will die from it just this year.

We are all aware of the statistics – 1 of every 8 women will get breast cancer – a number that guarantees that we all know of or have been victims. Breast cancer is the second leading cause of cancer death in women.

Fortunately, 8 of every 10 breast lumps are benign. Breast cancer in women under age 30 is very rare, with 75% of cases occurring in women over 50 years old. The 5-year overall survival rate for localized disease has risen to 98% due to better public awareness, early detection through screening, and improved treatment options.

Risk factors for breast cancer include:
• having a mother, sister, or daughter who had breast cancer before age 50
• having a male relative at any age with breast cancer
• if onset of menstruation occured before age 12 and/or menopause occurs after age 55
• never having children or having delivered a baby after age 30
• having a certain ethnic background such as Ashkenazi Jewish ancestry
• having a close relative with a known BRCA 1 or BRCA 2 gene mutation (see below)

Some preventative measures include maintaining a healthy weight, exercising, limiting alcohol intake, and stopping smoking. Aside from the clinical breast exam performed by the doctor every one to three years and monthly breast self-exams, there are also mammograms (standard X-ray or digital), ultrasounds, and MRIs that can provide early detection. Women should start getting annual or biennial screening mammograms by age 40 or earlier if strong risk factors exist.

If a breast or armpit lump detected, with or without overlying skin dimpling, clear or bloody nipple discharge and scale, or skin contour and color changes, see your doctor immediately for evaluation. Your physician may recommend a diagnostic imaging test with a biopsy. Treatment options include surgery, radiation, hormone- and chemotherapy according to the stage of the disease. Some women with very high risk for developing breast cancer opt for prophylactic removal of both breasts and/or ovaries before any possible tumor arises.

Five to 10% of all breast cancers are hereditary. The BRCA 1 & 2 genes (BReast CAncer) are ordinarily tumor suppressor genes meant to fight off cancer development, particularly for breast but also for ovarian, prostate, colon, and other tissues. If a woman tests positive for a mutated BRCA1 or 2 gene, her risk for developing breast cancer rises to 80%.

Some high-risk women (and men) can request getting tested for the BRCA 1 and BRCA 2 mutations. While those with a negative test feel relief, those with positive results showing the abnormal gene(s) may find themselves in an emotional, medical, and ethical Pandora’s Box. On one hand, they can get screening and subsequent early intervention if tumor is detected, but if the screening tests are negative, there is anxiety from the anticipation of possible future cancer. In addition, there may be genetic discrimination from employers and insurance companies that arise from having a positive result documented in the medical record. Thus, many people may confidentially seek to pay for the test out-of-pocket despite the potential high cost of this test.

Those interested in getting tested should first talk to their physicians and a genetics specialist, and then also research their insurance policies and state privacy and anti-discrimination laws. In Texas, the Genetic Information Non-discrimination Act of 2007 forbids employment and enrollment discrimination by employers and health insurances based on genetic testing.

Will we ever be able prevent heart disease, cancer, Alzheimer’s, and external aging with just pills, creams, and shots? Theories of disease and aging involve concepts of free radical interactions in body biochemistry. While most people have heard of “free radicals,” what exactly are they, what do they do, and why are antioxidants are so important to fight these scavengers?
Free radicals are molecules that are atomically unstable and thus highly reactive due to lack of a complete electron subset in their outer orbit. They take an electron from a more vulnerable molecule thus rendering that latter substance unstable (oxidation reaction). Antioxidants, on the other hand, have the capability to donate an electron to help stabilize molecules (aka reduction). Luckily, we do have repair enzymes in our bodies to inhibit overzealous free radical interactions and promote effects of antioxidants.

Free radicals often involve the oxygen molecule, thereby forming reactive oxygen species, which oxidize and damage cell components such as DNA, lipids, and proteins. Free radicals can be in the form of air pollution, excess sunlight, alcohol, smoking, and even internal stress (from a rise in our adrenalin levels). In our bodies, there are complex cascades where both free radicals and antioxidants are necessary for maintaining health. It is imbalances that can cause disease.

For instance, theories of carcinogenesis conceptualize that free radicals prevent proper DNA repair mechanisms, thereby perpetuating DNA mutations, leading to a cascade that causes uncontrolled cell growth. Likewise, internal markers of aging, such as atherosclerosis, also involve oxidative stress on lipids, specifically low-density lipoproteins or LDLs, that cause plaques and ultimately blockage on artery walls. This blockage causes to heart disease and stroke. And lastly, external markers of aging such as skin wrinkling also involve free radical-induced collagen breakdown through excess sun exposure and smoking.

Antioxidants such as vitamin A,C,E, and polyphenols (often from green tea), as well as lutein, lycopene, and selenium, are some of the body’s major antioxidants. While we have natural antioxidants and enzyme repair systems in our bodies, we also obtain much of our antioxidants from our diet, specifically diets rich in plant matter such as fruits and vegetables and legumes. Internal consumption and even topical placement through creams if they are able to penetrate deep enough into the skin, can slow down damage to our cells.

Foods with the highest antioxidant properties judged by the ORAC scale (aka, Oxygen Radical Absorbance Capacity) include: beans, berries (acai seems to be the berry of the moment), apples, green tea, dark chocolate/cocoa, red wine, certain nut and seeds, and green, leafy vegetables. Diets rich in these foods promote good health – not just through their high antioxidant levels, but also through their high fiber, relatively low-calorie, and nutrient-rich properties.

While the role of free radicals is not the only factor in disease and aging, it is part of the story, just as antioxidants may be part of the anti-aging and good-health panacea that we are all seeking.

Health Effects of Alcohol

The holiday season wouldn’t be the holidays without the five “f’s” – food, family, friends, fun, and fermentation. Some cultures view alcohol as an essential part of social and culinary life, and others shun it. Regardless of viewpoint, medical research has shown us some mild potential benefits of alcohol consumption and the many dangers of overconsumption.

Perhaps the “healthiest” alcoholic beverage to consume is red wine or a dark beer. The depth of color of alcohol is partly determined by the flavonoids and polyphenols in the beverage. These chemicals, and specifically another chemical called resveratrol, are anti-inflammatory and are anti-oxidants, so they can improve overall cardiovascular health.

Moderate alcohol intake for those who already drink, ie 1-2 drinks per day on average for men and 1 drink a day for women, also can modestly increase ”good” high-density lipoproteins (HDLs), lower blood pressure, and provide anti-clotting properties to the blood. A “drink” is defined as about one 12 oz. beer, 4 oz. of wine, 1.5 oz. of 80-proof spirits, or 1 oz. of 100-proof spirits. The American Heart Association does not recommend starting alcohol intake for these mild benefits, and instead recommends a combination of daily exercise and a healthy diet, sometimes in addition to lipid-lowering medication, to increase HDLs and decrease the “bad” low-density lipoproteins (LDLs). Some even speculate that eating red grapes or drinking red grape juice may provide the same benefit.

On the flip side, science has proven that too much alcohol can increase triglycerides, another component of blood lipids, and increase risk of stroke, cardiac arrhythmias, high blood pressure, heart failure, certain cancers, liver disease, fetal alcohol syndrome, obesity and diabetes, suicide risk, and accidents; and the list goes on.

How can such a simple molecule, two carbon, one oxygen, and five hydrogen atoms, cause such potential havoc in our bodies? First, the ethanol gets absorbed from our gastrointestinal system to our bloodstream, and then gets metabolized mainly by our liver and less so by our kidneys where the toxic byproducts taken up preferentially by tissue with high water contents. Also, because of the simple chemical structure, it is able to pass through the Blood-Brain Barrier. So our brain gets a double whammy, which is why the immediate alcohol effects include social “relaxation” and loss of inhibition and then memory and judgment impairment. But no body system is left unaffected, causing adverse effects to our brain, liver, heart, muscles, kidneys, stomach, lungs, bones, endocrine, reproductive, and immune system with long-term excessive alcohol consumption.

If and when consuming alcohol over the holidays, it is extremely important to drink on a full stomach, drink in limited amounts, and to drink slowly. Blood alcohol concentration (BAC) is affected by gender, weight, and body fat of the individual. A rule of thumb is that one drink, as defined above, can increase the BAC by 0.02 to 0.05%. It can take 1.5 to 3 hours for the BAC to go back down to zero. In all states in the US, a BAC equal to or above 0.08% constitutes intoxication. In certain individuals in certain circumstances, as little as one to one and a half drinks can cause the BAC to go up to 0.08%.

Lastly, to also be safe, avoid alcohol with sedating antihistamines like Benadryl, narcotic pain medications like codeine and vicodin, anti-anxiety medications and antidepressants, sleep and anti-seizure
and cough medications, certain antibiotics, muscle relaxants, and even herbal oral medications such as St. Johns Wart, Kava Kava, chamomile, lavender, and valerian. Speak to your doctor for advice.
Enjoy in moderation, be safe, and Happy New Year!!!
