  • The Grapefruit Effect

    MEDICAL NEWS

    Image of pill bottle with warning about grapefruit.

    Grapefruit can interact with your drugs. And your doctor may not be aware of it. An article in the Canadian Medical Association Journal points out that drug interactions with grapefruit were noted more than 20 years ago.

    Recently, more and more commonly prescribed newer drugs are found to interact with grapefruit (the fruit and the juice) and can cause serious side effects. Problems can occur even if the grapefruit is eaten hours before taking certain medications.

    Adverse effects include sudden death, acute kidney failure, respiratory failure, gastrointestinal bleeding, bone marrow suppression in ill people, and other serious side effects.

    There are more than 85 drugs that may interact with grapefruit, and 43 can have serious side effects. Other citrus fruits such as Seville oranges, often used in marmalade, limes and pomelos also contain the active ingredients (furanocoumarins) that interact with grapefruit.

    The best advice is to discuss all your medications with your doctor and pharmacist and ask about interactions with grapefruit.

  • When Allergies Get Real Serious

    MEDICAL NEWS

    A severe allergic reaction can be life threatening. It’s called anaphylaxis. The symptoms begin within minutes of eating a trigger food or after a bee sting or touching poison ivy. Some drugs can cause these serious reactions too. The Asthma and Allergy Foundation of America offers this safety advice:

    *  Know the symptoms: flushed skin, rash, tissue swelling, stuffy nose, sweating, panting, nausea, stomach cramps, rapid pulse, wheezing, convulsions, or fainting.

    *  Know what you’re allergic to: check food labels and ingredients. Ask at restaurants if you’re unsure if a menu item contains something you’re allergic to. Skin or blood tests done by a specialist can confirm that you’re sensitive to certain substances that can cause a severe reaction.

    *  Carry an auto-injectable epinephrine device that allows you to use a rescue medication until emergency help arrives.

    *  Wear a medical alert bracelet to let others know of your allergy.

    *  Anaphylaxis is a 9-1-1 medical emergency.

  • Can Birth Defects Be Prevented?

    MEDICAL NEWS

    Image of pregnant women.

    Birth defects can be devastating for parents and their baby. Sadly, many birth defects happen without an obvious cause and cannot be avoided. But, doctors know there are some things a woman can do before and during pregnancy to help lower the risk of birth defects. They include:

    Take 400 micrograms (mcg) of folic acid every day.

    This is a B vitamin that can reduce the risk of certain brain and spine defects. Experts recommend taking it even before you get pregnant.

    Get good medical care.

    See your doctor regularly and tell him or her if you plan to get pregnant. Begin prenatal care as soon as possible after you become pregnant. It’s important to talk about any health problems you may have and any medicines you take. You’ll also need tests to check for high blood pressure, blood sugar, and other possible pregnancy problems. You may also need certain vaccines (shots) to prevent illness and avoid some birth defects.

    Avoid alcohol, tobacco products, and any street drugs including marijuana.

    These can harm a developing baby.

    Work toward a healthy weight.

    Overweight women have a higher risk of birth defects. Talk to your doctor about safe ways to achieve a healthy weight. Ask your doctor how much weight you should gain during pregnancy.

  • Heat & Humidity:A Dangerous Combination

    MEDICAL NEWS

    Image of young women suffering heat exhaustion.

    Heat and humidity can trigger three major illnesses, according to Dr. Eric Kirkendall, of Cincinnati Children’s Hospital Medical Center:

    Heat strokesymptoms include hot flushed skin, high fevers (over 104ºF), altered mental states such as confusion, and can be accompanied by seizures. Heat stroke is a life-threatening emergency and needs to be treated promptly.

    Heat stroke is a 911 emergency. Cool the person off as quickly as possible while waiting for medical services to arrive. Move the person to a cool shady place or an air-conditioned room; sponge the entire body surface with cool water (as tolerated without causing shivering); and fan the person to increase heat loss from evaporation. Keep the feet elevated to counteract shock. If the person is awake, give him or her as much cold water to drink as he or she can tolerate. Fever medicines are of no value for heat stroke.

    Heat exhaustionsymptoms include pale skin, profuse sweating, nausea, vomiting, muscle cramps, or weakness. It is less severe than heat stroke but is still dangerous and may require medical attention.

    For heat exhaustion, put the person in a cool place indoors or in the shade. Have him or her lie down with the feet elevated. Undress the person (except for underwear) so the body surface can give off heat. Sponge the entire body surface continuously with cool water without causing shivering. Fan the person to increase heat loss from evaporation. Give as much cool, not cold water or sport drinks as the person tolerates until he or she feels better. If symptoms do not improve or the person gets light-headed or faints, get medical care right away.

    Heat crampsare most common in the abdomen and legs, especially the calf or thigh muscles. Tightness or hand spasms can also occur, but fever is not a symptom.

    For heat cramps, monitor physical activity and make sure children don’t overly exert themselves. Adults can self-monitor. Make sure children drink plenty of water often. Encourage frequent breaks from physical activity to cool down and gently stretch muscles.

  • Living Well With Psoriasis

    MEDICAL NEWS

    Image of doctor looking at patients rash on arm.

    Psoriasis is a condition that causes skin cells to grow too quickly. These extra skin cells build up and form scaly patches, redness or a rash.

    There are several different types of psoriasis that look and feel different. Sometimes, a person may have one type of psoriasis and it later turns into another type. Experts aren’t sure what causes psoriasis, but they believe the immune system and a person’s genes are involved.

    Fortunately, there are ways to help manage this condition and live a healthy life with this disease. Try these tips:

    *  Know your triggers. Many people find that psoriasis flares up at certain times. Stress, skin injury, certain medications, infections or illnesses can cause a psoriasis flare-up. Talk with your doctor about healthy ways to avoid your triggers.

    *  Focus on all-around good health. A healthy diet and exercise will help you manage psoriasis. For example, being overweight can make psoriasis worse. In addition, people with psoriasis are at a higher risk of getting heart disease and diabetes.

    *  Don’t smoke. Smoking puts stress on the body and harms the immune system and skin.

    *  Work with your doctor to manage itching. Many people with psoriasis have itching that interferes with life. Keeping skin moisturized, cold packs and over-the-counter itch creams may help. If these remedies don’t work, ask your doctor about prescription options.

    *  Know the signs of psoriatic arthritis. Up to 30 percent of people with psoriasis will get psoriatic arthritis. This type of arthritis can be very painful and cause damage to your joints. Achy joints, especially in the morning, are one sign. Fingernails and toenails may also look different. They may get ridges, pits or a yellow or orange color. See your doctor if you notice any of these changes.

    *  Keep mental health in mind. Some people with psoriasis get depression or anxiety. Plus, your mental health plays an important role in overall health. See your doctor and ask about treatment for these conditions.

    *  Don’t stop taking medicines without your doctor’s approval. If you suddenly stop your psoriasis medicine, it can make the psoriasis more severe. If you need help paying for your medication, talk to your doctor. There may be financial assistance programs available for people with psoriasis.

  • Sepsis: Be Aware Of This Deadly Condition

    MEDICAL NEWS

    Image of sick women in bed.

    Sepsis is among the top causes of disease-related death in our country, killing about 200,000 people each year. Actress Patty Duke’s recent death from sepsis brought more attention to this dangerous disease. It’s important to know the signs of sepsis so you can seek emergency medical care for this serious condition. Early treatment can save lives.

    Sepsis is a strong and harmful reaction of the body’s immune system. It can be triggered by common infections, such as pneumonia, a urinary tract infection, or even a minor infection like a cut or scrape, if it becomes infected and the infection spreads.

    Most of the time, these infections don’t cause sepsis. But when sepsis does occur, it can cause a dangerous drop in blood pressure, resulting in organ failure and death. It tends to affect the very young, the elderly or those with weakened immune systems.

    Influenza vaccines and pneumococcal vaccines may help prevent sepsis. Consider getting these vaccines to reduce your risk.

  • The Lowdown On High Blood Pressure

    MEDICAL NEWS

    Image of women having her blood pressure checked.

    Because 1 in 3 American adults suffers from high blood pressure, regular and accurate blood pressure checks are important for correctly diagnosing and treating hypertension (the medical term for high blood pressure).

    Dr. Robert Zelis, a cardiologist at Penn State Milton S. Hershey Medical Center, says there are three groups of people who may want to consider checking blood pressure on their own, in addition to having it measured at their annual physical exam.

    *  The first is those with so-called “white-coat hypertension.” These are patients who get so worked up about being in a doctor’s office that their readings will always be high there.

    *  The second is those who already take medication to control their blood pressure and need to monitor how it’s working.

    *  The third is those who suffer from chronic conditions such as diabetes or high cholesterol or who have risk factors such as obesity, smoking, or a strong family history of hypertension.

    Whether a blood pressure check is done at the doctor’s office or at home, it’s important to follow the same procedure:

    *  Make sure the blood pressure cuff is large enough and easy to use.

    *  Sit in a chair with a straight back, with both feet flat on the floor. Your legs should not be crossed.

    *  Make sure your arm is supported on something such as a table or armrest.

    *  Don’t take a measurement with the cuff placed on top of clothing. Bare skin is best.

    *  Wait 30 seconds after sitting down before you take your measurement.

    *  Take a second reading 30 seconds after you have finished the first to confirm your initial results.

    *  Take the measurements at the same time of day.

    *  Record your results to spot patterns.

  • Why Afib Matters

    MEDICAL NEWS

    Close up image of a doctor's hand drawing a heart with heart beats.

    Atrial fibrillation, or “AFib,” is an irregular or rapid heartbeat. It happens when the upper chambers of the heart don’t pump as they should. The American Heart Association says many people don’t realize that AFib can be an extremely dangerous condition. In fact, if AFib isn’t treated, it can lead to dangerous blood clots and stroke. It can also make the heart get weaker and enlarged, causing congestive heart failure.

    Symptoms of AFib

    It can be hard to know whether you have AFib, because symptoms can be different for each person.

    *  Heartbeat that feels fast, irregular, “thumping,” or fluttering

    *  Feeling tired, weak or dizzy

    *  Shortness of breath and/or anxiety

    *  Sweating

    *  Feeling very fatigued during exercise

    *  Confusion

    *  Chest pain or pressure: This is also a sign of heart attack. Call 9-1-1 if you notice this symptom. If you think you could be having a heart attack, don’t wait. Get emergency medical help immediately.

    It’s important to talk to your doctor about your AFib symptoms and how to manage them. Some conditions like diabetes and heart disease, or having a family history of AFib, mean you could be at higher risk for AFib.

    Preventing AFib

    Like many heart conditions, the risk of AFib can be lowered by following a healthy lifestyle. This may include:

    *  Regular exercise

    *  A healthy diet low in saturated and trans fats, sodium (salt), and cholesterol

    *  Not smoking: if you smoke, get help quitting atwww.smokefree.gov

    *  Getting checked for – and treating – high blood pressure (hypertension)

    *  Keeping cholesterol under control and getting regular cholesterol checks

    *  Working toward a healthy weight, if weight loss is needed

    *  Avoiding high amounts of alcohol and caffeine

    *  Treating obstructive sleep apnea, a sleep disorder that increases the risk of AFib.

    Treating AFib

    Treatment for AFib will depend on a person’s health history and how severe the AFib is. Some people may need medications, such as blood thinners and drugs that reduce clotting. Some people can keep AFib under control with blood pressure medicine.

    A procedure known as electrical cardioversion may be performed when medications aren’t suitable. This is a non-surgical procedure that helps “reset” the heart’s rhythm. Other non-surgical procedures may also be discussed. In some cases, surgery may be needed. Only you and your doctor can determine what treatment is best for you.

  • 5 Things To Know About Lung Cancer

    MEDICAL NEWS

    Image of women getting a lung scan.

    Lung cancer is the country’s leading cause of cancer death. Many of the 160,000 deaths from lung cancer in the U.S. can be prevented. Dr. Bruce Johnson, the director of the Lowe Center for Thoracic Oncology at Dana-Farber Cancer Institute, sorts out the facts about lung cancer and offers simple ways to reduce risk.

    1. Lung cancer targets more than just smokers. The greatest risk factor for lung cancer is smoking, but nonsmokers can also develop lung cancer. About 10 to 15 percent of lung cancer cases occur in nonsmokers, many of them women.

    2. Know the warning signs. They can be subtle but symptoms to be aware of include a cough that does not go away, shortness of breath, back and shoulder pain, and coughing up blood. This could be a sign of something serious and should be discussed with a doctor.

    3. It’s never too late to quit smoking. People who stop and remain a nonsmoker for at least 10 to 20 years can cut their risk of developing lung cancer by 50 to 75 percent.

    4. CT screenings can save lives. Lung cancer can be difficult to detect and, until recently, there has not been a good screening test. But results from the National Lung Screening Trial suggest that screening high-risk people with low-dose CT scans can detect tumors at an earlier stage, resulting in improved lung cancer survival. Screening is currently recommended for people who are between the ages of 55 and 74 and who have smoked a pack a day for 30 years and quit fewer than 15 years ago.

    5. New therapies show promise. Thanks to advances in the last decade, new targeted therapies offer more treatment options for patients.
