How to Choose Your Sunscreen

It’s no secret that sunscreen offers the best protection against skin cancer next to staying out of the sun altogether or covering up with sun protective clothing. However, most people don’t realize that the kind of sunscreen we use is also important. Did you know there are two main kinds of sunscreen? Chemical sunscreen and physical sunscreen.

Chemical Sunscreen vs. Physical Sunscreen – What’s the Difference?

A sunscreen is a compound (or lotion) that uses agents to block, deflect or reflect the sun’s rays.

To be effective, we recommend that all sunscreens be liberally applied (at least one ounce for the entire body) to all exposed areas of the body, at least 15 minutes before going outside.

Chemical sunscreens use up to a dozen ingredients that, when applied, are absorbed in the top layer of skin. They react with the skin to absorb UV rays and convert them into energy before they can harm the skin.

Chemical sunscreens aren’t as thick as physical ones, so they are often used in sunscreens specifically made for the face as well as those found in spray bottles. Since chemical sunscreens need to be absorbed into the skin, they must be applied at least 20 to 30 minutes before heading outdoors.

Physical sunscreens, sometimes called “natural or mineral” sunscreens, include two ingredients: zinc oxide and titanium dioxide. Together, these ingredients sit on top of the skin and deflect or reflect the sun’s rays.

Think of physical sunscreens like a shield, while chemical sunscreens are absorbed into the skin. Both ingredients work well to protect from UVA and UVB (broad spectrum) rays. Since physical sunscreens are thicker, they can leave a white cast on the skin.

Which Sunscreen Is Right for You?

Those with sensitive skin, especially young children, should opt for a physical/mineral sunscreen since those ingredients are milder. Those with darker skin may opt for a chemical sunscreen, since they don’t leave a white cast.

According to plastic surgeon, Ivona Percec, MD, PhD, “A chemical sunscreen really just protects against UB – the burning rays. In two hours that’s degraded by the sun. The mineral block [physical sunscreen] is the much better block because it protects against both UVA and UVP.”

Both types of sunscreen provide adequate protection. Your personal preference may help you decide what type of sunscreen is right for you.

Fitness Trackers – What’s All the Hype About?

Becoming more physically active and shedding a few pounds are two goals most adults strive to achieve. In today's busy world, though, it can sometimes be quite challenging to do so.

Perhaps in the past you've tried various diets and exercise programs, seeing little to
no results? And you ask yourself 'what’s left to try?' You want to be more active and healthier in general, but you just don't have the time to devote to it.

Enter the newest fitness craze - wireless fitness trackers.

These small devices are typically worn around the wrist and can track information about your overall health. Fitness trackers can sync wirelessly with computers or smartphones to display data including the number of steps taken throughout the day, calories burned, and the quality of your sleep. Also, most trackers allow you to enter the foods you've eaten throughout the day to keep track of calories and nutrition.

This latest advancement in personal fitness has many ecstatic, claiming it’s the answer to long-lasting weight loss. Could it be true? Do fitness trackers really help you effectively lose weight and live a sustainable, healthy lifestyle?

"While fitness trackers certainly can be a helpful tool to track health and weight loss progress, the individual still has to stay motivated to make dietary changes or keep up with that new exercise routine," says Lori M. Noble, MD, a primary care physician at Spruce Internal Medicine, located at the new Penn Medicine Washington Square. "Fitness technology can certainly add positive reinforcement, but it can’t pick an individual up off their couch or take the donut out of their hand."

Still, the health and fitness technology market is growing by 20% each year, making fitness trackers more popular by the minute. There are dozens of trackers currently on the market -- FitBit, Jawbone UP, and the Nike Fuelband being the most common.

All of these devices have corresponding apps that allow you to view and interact with all of the information it’s capturing. Most also have social features that allow you to connect with friends and other users online.

In addition to these apps, there are several health and fitness programs that have similar lifestyle tools to help you track your activity. MyFitnessPal, RunKeeper, Fitness Builder, and MapMyFitness are all apps that help you track your fitness without having to buy a somewhat costly fitness tracker.

Many people have made tracking their fitness a part of their daily lives. Because this technology is still somewhat new, there are questions that people have about the effectiveness of the devices.

 Fitness tracker or not, the most important thing to do is to get out there and stay active.

"Perhaps one of the most basic keys to sticking with an exercise routine is to make it fun – pick an activity that you enjoy so you actually look forward to scheduling it into your day," says Dr. Noble. "And if you start to get bored, change it up.  Rotating activities keeps your mind and your body engaged."

For those of you looking for extra motivation, sign up for the Penn Medicine Radnor Run on October 26, 2014! This fun, 5-mile run will give you something to work towards as you stay active this summer.

The Benefits of Physical Activity

Risha Hertz, APNC, discusses the numerous health benefits of keeping an active lifestyle. Risha practices at Penn Family Medicine Gibbsboro.

Risha Hertz, APNC

Just because there’s been a dip in the temperature, doesn’t mean it’s time to hibernate until next spring. It’s important for you and your family to stay active throughout the year.

For many of us, as kids, our parents probably sounded like a broken record: Go outside and play! Sitting inside and watching television is not good for your health.

As it turns out, they were right. Being sedentary or not really engaging in any physical exertion, can take a toll:

“Regular physical activity greatly helps many of the body’s systems function better,” said Risha Hertz, APNC. “For those that aren’t very active, they face increased chances of becoming overweight and developing a number of chronic diseases.”

“For my patients that are just becoming more active, it is a joy to see the positive effects just days into their individualized activity program.”

Below are just a few of the benefits of regular exercise and living a healthy lifestyle.

Controls weight and improves appearance. Perhaps most important, exercise can help prevent excess weight gain or help you to maintain weight loss. Adding muscle also helps your body look lean and toned. Exercise also makes you sweat, which purges the body of toxins that can clog pores and plague your skin with pimples and blemishes.

Strengthens mental acuity. According to the Centers for Disease Control and Prevention, research has shown that doing aerobics or a mix of aerobics and muscle-strengthening activities three to five times a week gives you numerous mental health benefits. Regular physical activity can help improve your thinking, learning, concentration and reaction time as you age. It can also reduce the risk of depression and may help you sleep better.

Gives you an energy boost. Exercise and physical activity transport oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently. When your lungs and heart are working more efficiently, you have more energy.

Reduces risk of injury. Exercise is critical for strong muscles and bones. As you age, muscle strength declines, but studies show that people who exercise on a regular basis are stronger and leaner than others in their age group. Because muscles act as both cushions and shock absorbers for your joints, strong muscles help to protect joints, improve balance and can help reduce the pain of arthritis.

Reduce risk of disease. Two of the leading causes of death in the United States are heart disease and stroke. Living an active lifestyle increases your high-density lipoprotein (HDL), or "good," cholesterol and decreases unhealthy triglycerides. This combination, which helps blood flow, decreases the risk of cardiovascular disease. Regular activity can also help prevent a number of other health concerns, including stroke, metabolic syndrome, type 2 diabetes, depression, some types of cancer and arthritis.

Now that you know the positive effects of living an active lifestyle, how do you get started?

“At Penn Medicine, we partner with our patients to develop individualized activity programs that will work for them,” said Hertz. “Many think that they have to go to the gym for half an hour to an hour and perform weight lifting and cardio. Formal activity is great, but is not for everyone. My patients and I explore ways in which they can become more active throughout the day as much as possible.”

If you haven’t exercised consistently in some time, you might want to talk to your primary care doctor first.

How to Have Your “Cake” and Eat It, Too

Lori M. Noble, MD, a primary care physician at Spruce Internal Medicine, located at the new Penn Medicine Washington Square building, offers tips on how to satisfy your sweet tooth and do so in a healthy way.

Lori M. Noble, MD

For those that don’t know me, I have a bit of a sweet tooth. Ok, I'm a dessert-a-holic. But, throughout my medical training, I became more aware of the potential detriment this habit of mine could have on my health. It is estimated that diabetes affects 382 million people worldwide and the prevalence continues to increase in every country.

Among adults in the United States, the estimated overall prevalence of diabetes ranges from 5.8 to 12.9 percent. One very large, well-respected study - the community-based Framingham Heart Study- has found that the incidence of type 2 diabetes doubled from the 1970's to the 1990's. Diabetes is one of our country's leading health problems, and as I learned more, I decided I didn't want to become a statistic.

So, over the years, I've found creative ways to satisfy my craving for sweets without breaking the sugar bank. Here are some of the tasty tricks I've developed to make dessert both delicious and healthy:

• Fruit crisp/cobbler: Slice up a banana or an apple and brown it in a sauté pan that has been sprayed with some non-stick cooking spray. Sprinkle with cinnamon and put the warm fruit over ½ cup of granola. Add two tablespoons of low-fat whipped topping – delicious!
• "Ice cream": Freeze the older, brown bananas that you would normally wind up throwing out. Once frozen, grind them up in a food processor until they are smooth and creamy. You now have what tastes and looks like ice cream without the added sugar and fat! Mix in whatever you'd like – berries, some crushed graham crackers, a tablespoon of chocolate chips…the possibilities are endless!
• Oatmeal truffles: Mix one cup of instant oats with ½ cup of dried figs, dates or raisins, two tablespoons of skim milk, one tablespoon of honey and cinnamon in a food processor. Once well mixed, form into balls, roll into coconut flakes (optional) and chill in the fridge for 30 minutes.
• Bread pudding: Take two pieces of whole wheat bread (stale or fresh) and break them into small pieces, set aside. Mix ¼ cup of egg whites, two tablespoons of raisins, ½ teaspoon of salt, cinnamon to taste and one tablespoon of melted butter. Pour the mixture over the bread, transfer to an oven-safe dish and bake at 350 degrees until warm, about 15-20 minutes.

For those looking for store bought options that don't require preparation, here are two of my favorites:

• Skinny Cow: Skinny Cow ice cream sandwiches or ice cream popsicles. They typically run between 100-150 calories and are very satisfying.
• Weight Watchers muffins: Add a side of fresh fruit and you've got a high fiber, cake-like dessert.

So next time you are looking for something sweet, try one of these healthy, satisfying options that have earned high praise in my house and should do the trick in yours.

A Pioneer in the Use of Deep Brain Stimulation

“Our mission is to innovate, to constantly find new answers. And no one is doing that better today than the people at Penn Medicine.” - Gordon Baltuch, MD

Many people describe Gordon Baltuch, MD, Director of the Center for Functional and Restorative Neurosurgery, as a man of vision. This is not surprising, considering the fact that he’s been developing this skill since he was a boy.

“When I was a child, I was very close to my grandfather, who was a physician in a very different time and place,” Dr. Baltuch says, his eyes twinkling at the thought. “Sometimes he would go to patients’ houses. Sometimes patients would come to our house. On busy days, the living room became the waiting room. It was, at the end of the day, a very social experience.

“It was there that I first realized I could see myself going into medicine.”

Gordon Baltuch, MD

With this goal in mind, he pursued an undergraduate degree at Harvard, knowing all along what the next step in his path would be. In medical school, he gravitated at first towards neuroscience, then towards the more unknown world of neurosurgery, which just happened to be “a good fit.” The wisdom of his choice of medical specialization was confirmed by his early experience working at the Montreal Neurological Institute and Hospital in the late 1980s, where he was fortunate to be able to witness firsthand and later take part in some of the leading-edge work of the day at the intersection of neuroscience and medicine.

Then, once again, he had a vision of new and greater possibilities in his chosen field. So, in 1994, he packed his bags and headed for Europe, where Professor Alim Louis Benabid was pioneering deep brain stimulation (DBS) therapy for Parkinson's disease.

The cause of Parkinson’s disease, a degenerative disorder of the central nervous system, was at that time and is to this day unknown. The death of dopamine-generating cells in the substantia nigra part of the brain leads to the motor symptoms that traditionally characterize Parkinson’s, beginning with shaking, rigidity and other movement-related manifestations. Cognitive and behavioral problems, even dementia, are associated with advanced stages of the disease. The accumulation of rogue proteins called alpha-synucleins, combined with the lack of healthy dopamine generation and activity, causes the circuitry of the midbrain to function in abnormal electrical patterns and sometimes, in severe cases, to cease functioning at all.
