The Right and Wrong Way to Apply Bug Spray
By Dana Sparks 
While insect repellent is a good way to ward off disease-carrying insects, you may be making common bug-spray mistakes. One of the common mistakes is to not read bug-spray labels. The repellent you choose should depend on the type of insect you’re trying to ward off. The Centers for Disease Control and Prevention suggest using repellents with picaridin, IR3535, or oil of lemon eucalyptus to prevent mosquito bites, while a spray with 20 percent or more DEET should be used to fight both ticks and mosquitos.
According to Bobbi Pritt, M.D., Director of the Clinical Parasitology Laboratory at Mayo Clinic, “Permethrin-containing products can also be used directly on clothing but should not be applied to skin.” In addition to being aware of bug-spray ingredients, it’s important to wear it whenever bugs may be present.

Elbow pain: Recovery quicker working with a health care provider
When elbow pain stops golf, tennis, gardening or household chores, it’s wise to see a doctor to determine the cause and a treatment plan. The July issue of Mayo Clinic Health Letter covers common causes of elbow pain, self-care tips and why seeing a doctor sooner ― rather than later ― is a good idea.
In the absence of a bone fracture, most elbow injuries aren’t serious. But nagging pain can interfere with sports and day-to-day activities. Most elbow pain is related to overuse that results in irritation and tissue degeneration near areas where tendons connect to bones of the elbow joint. Read the rest of this entry »

Staying Safe in Scorching Temperatures
By Dana Sparks
Today is National Heatstroke Prevention Day
Many northern communities in the United States are used to the winter thermometer dipping into negative numbers, but summer heat can often rival the challenges of a cold, snowy winter. As we move into August, one of the hottest months of the year, temperatures can easily exceed 100 degrees F, bringing the threat of heat illness and heat-related afflictions. Regional director of Mayo Clinic Health System Urgent Care, Ruth Bolton, M.D., offers this important preventive information.
Q. What is heat illness?
A. Heat illness is exactly what it sounds like — a sickness caused by heat. Heat illness can take multiple forms, each ranging in severity. The different types of heat illness, from mildest to most dangerous, include heat cramps, heat exhaustion and heat stroke.
Q. What are the symptoms of heat illness?

Algorithm Reduces Use of CT Scans when Diagnosing Children with Appendicitis
By Chloe Piepho 
ROCHESTER, Minn. — Implementation of an algorithm aimed to diagnose pediatric patients with suspected appendicitis reduces the utilization of computed tomography (CT) scans, without affecting diagnostic accuracy, Mayo Clinic Children's Center researchers have found. The study was recently published in the journal Surgery.
Acute appendicitis is the most common cause of acute abdominal pain in children. Appendicitis occurs when the appendix becomes inflamed and filled with pus. CT scans are often used to diagnose acute appendicitis because they are accurate, widely available and have the ability to provide clinicians with advanced information in appendicitis cases suspected of complications.
However, CT scans are expensive and expose patients to ionizing radiation. “This algorithm was developed by a multidisciplinary group of pediatric emergency room physicians, pediatric surgeons and radiologists to eliminate unnecessary exposure to radiation,” explains Michael B. Ishitani, M.D., lead author of the study.

Eye-tracking devices offer added pilot safety, Mayo Clinic study says
By Jim McVeigh
SCOTTSDALE, Ariz. – The use of small, portable eye-tracking devices in cockpits could be a future additional safeguard for pilots and other safety critical operators, according to a Mayo Clinic study published in the July issue of Aviation, Space and Environmental Medicine.
Eye movement metrics have been recognized as promising indicators of altered cognitive performance caused by hypoxia at high altitudes. Hypoxia is a lower than normal level of oxygen in your blood. To function properly, your body needs a certain level of oxygen circulating in the blood to cells and tissues. When this level of oxygen falls below a certain amount, hypoxia can cause a variety of symptoms including shortness of breath, impaired speech, slowed reaction time and passing out which can be a safety threat at high altitudes.

Most people have heard that carrots are good for their eyes, but do you know that other foods help protect vision and prevent eye disease? The National Eye Institute and other vision experts note that a healthy diet is an important factor in eye health. Researchers have found that certain nutrients with antioxidant properties are beneficial. These include carotenoid compounds such as beta-carotene, lutein and zeaxanthin, and vitamins C and E. Zinc and omega-3 fatty acids are also important for eye health.
Mayo Clinic eye and nutrition experts offer the following lists to help you choose foods for better eye health:
- Vegetables: Kale, collard greens, peppers, broccoli, sweet potato, spinach, peas, pumpkin, carrots and Swiss chard
- Fruits: Peaches, blueberries, oranges, tangerines, mango, tomato, apricot, papaya, cantaloupe, honeydew, avocado and grapefruit
- Sources of zinc: King crab, lamb, bulgur, lean beef, fortified breakfast cereals, beans, lean pork, dark meat of poultry, whole-wheat or buckwheat flours, pumpkin seeds
- Omega-3-rich foods: Salmon, herring, tuna, mackerel, rainbow trout, sardines, flaxseed, English walnuts, canola oil, roasted soybeans

Bacardi’s Gift to Significantly Advance Mayo Clinic’s Regenerative Medicine Research
By Kevin Punsky 
JACKSONVILLE, Fla. — Imagine a future in which a new lung is grown for a patient in need, using the patient’s own cellular material, or a day when an injection of replacement cells will enable a patient to self-heal damage in the brain, nerves or other tissues.
Regenerative medicine is no longer science fiction, and a substantial gift from Jorge and Leslie Bacardi of the Bahamas will significantly accelerate the research of Mayo Clinic’s Center for Regenerative Medicine on the Florida campus. Read the rest of this entry »

Tuesday Q and A: Eye infections common, especially in children
By lizatorborg 
DEAR MAYO CLINIC: My grandson had a virus with flu symptoms. Then one of his eyes got very red, but it wasn’t itchy or mattered shut. When my daughter took him to the doctor, she was told it was the virus settling in his eye. But it wasn’t pink eye. What’s the difference between this type of eye infection and pink eye? Are the treatments different?
ANSWER: The two conditions you mention are both eye infections,
and they are actually also both forms of
pink eye. The difference is that the type of infection your grandson had is caused by a virus. The other is caused by bacteria. Viral eye infections typically do not require any treatment. Bacterial eye infections are usually treated with antibiotic eye drops.
Eye infections are common, especially in children. As in your grandson’s case, they often happen when a child has a cold. Both viral eye infections and bacterial eye infections are called conjunctivitis, or pink eye.

Rochester, Minn. — Mayo Clinic announced today a new health engagement platform called Mayo Clinic Healthy Living online. Designed for employers and other groups to help members improve and stay healthy, the platform focuses on lifestyle areas where change can have the most beneficial effect on overall health. As a result, this new solution promises positive results, not only for the individual, but for the employer/client in terms of controlling health care costs and optimizing performance and productivity. The science underpinning the platform draws upon the expertise of Mayo Clinic and leverages the new Mayo Clinic Healthy Living program as a learning lab to research and measure outcomes to improve health and wellness.
Mayo Clinic Healthy Living online is at the forefront of the next generation of digital wellness and lifestyle behavior change tools. The program is designed to engage members by leveraging new technologies, connectivity to remote devices, data-driven user personalization, incentive capabilities, and user-driven responsive design, all underpinned by evidence-based approaches validated though the medical practice and research at Mayo Clinic.
Mayo Clinic research was used to identify areas with the most potential to improve health.

DEAR MAYO CLINIC: My father, 68, has advanced emphysema. Medication for it doesn’t seem to help as much as it used to. We’ve heard that volume reduction surgery is sometimes used in cases like his. What does this surgery involve? What are the benefits? How do we find out if he’s a good candidate for it?
ANSWER: Lung volume reduction surgery can help treat some severe cases of emphysema. The procedure involves removing part of the damaged lung tissue, so the remaining healthy tissue can work better. But it is only appropriate in a small number of cases. A thorough medical evaluation would be necessary to see if your father might be a good candidate for lung volume reduction surgery.
Emphysema is a form of chronic obstructive pulmonary disease, or COPD, that damages the lungs’ air sacs, called alveoli. The alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually break down. That creates one larger air space instead of many small ones. This decreases the surface area of the lungs and lowers the amount of oxygen that reaches the bloodstream.
Emphysema cannot be cured. Medications and pulmonary rehabilitation are the main therapies for this disease. Medications including bronchodilators, inhaled steroids, oxygen and antibiotics often are used to help ease breathing problems and prevent flare-ups. Read the rest of this entry »
