Ticks!

SYNOPSIS of: "Tick-borne Diseases" by Sanson et al. and "Tick Removal," by Sloan et al., on Medscape            


What has eight legs, a capitulum, and drinks from a hypostome? If you guessed the tick, you’re right! In the U.S., tick season spans from April through September. The further one ventures out of the city and into the suburbs, an encounter with this eight-legged bloodsucker becomes more likely. In our neck of the woods, tick-infested areas include Gladwyne, the Wissahickon, and Valley Forge Park.
Ticks are vectors of disease, which is a fancy way of saying that they carry and transmit pathogens (disease-causing substances) to their hosts. In order to move on to the next developmental stage, these tiny vampires need to feed on blood.
The bad news is that ticks can transmit illnesses like Lyme disease, Rocky Mountain spotted fever, and tularemia (a serious infectious disease). The good news is that you are highly unlikely to get sick from a tick bite. For example, only around 2-3% of people bitten by Lyme ticks will develop Lyme disease.
You don’t need to overdo it when it comes to prevention. If you leave the house dressed like a Costa Rican bug-catcher about to venture into the rainforest to collect specimens, you’ve probably gone too far. Some commonsense tips:
·      Avoid crawling through bushes in which ticks may be lying in wait for a blood meal
·      Shower after spending time in outdoor areas known to be tick-infested. Examine yourself and your little ones thoroughly.
·      Use an anti-tick insect repellent. Make sure the brand you choose is approved for children. “Natural” does not mean safe for kids.
·      Treat your dog or cat with preventative treatments such as Frontline
Sometimes, despite your best preventative efforts, a tick will bite you. It is often painless. However, the area around the bite may become red, itch, or burn. Symptoms of transmitted disease usually do not show up until days to weeks later. Some general signs:
·      Fever
·      Flu-like symptoms
·      Numbness
·      Rash
·      Shortness of breath
·      Confusion
Except for the rash, these symptoms warrant a visit to the emergency room. In addition, tell your physician about the bite as soon as possible if you are pregnant or immunosuppressed (your immune system is compromised by chronic disease or a drug therapy).
The sooner you get rid of a tick, the better your chances of avoiding disease. Contrary to popular belief, running around in circles, waving your hands in the air, and shouting will not induce the tick to unhook itself from your skin. Applying a hot match head to the tick is not advisable either; this could actually prompt the tick to release more pathogens!
The best way to remove a tick can be found in the medicine cabinet; a curved or pointed set of tweezers is the instrument of choice. If possible, put on a pair of latex gloves to prevent the tick’s nasty pathogens from getting on your hands. With the tweezers, flip the critter on its back. Then, pinch the tick and pull gently until it comes out.
Make sure that you do not leave the head and mouthparts in your skin. However tempting, do not stomp on, squish, or crush the tick after removal. Flush it down the toilet. If you want to keep your tick as a specimen to show your doctor in case you get sick, house it in a lidded jar.
Wash the affected area with soap and water. After it dries, apply an antibiotic ointment. Any further treatment will depend on your diagnosis. Fortunately, most tick bites do not result in serious illness, so don’t allow the small risk of being bitten deter you from enjoying all the outdoor fun that summer has to offer.

John Heinz Wildlife Refuge at Tinicum

On a clear, sunny day in April 1991, a small plane carrying Republican Senator Henry John Heinz III and a helicopter dispatched to inspect the landing gear of the plane collided in mid-air over Lower Merion Elementary School, near Narberth, PA. Tragically, everyone aboard both aircraft, as well as two children on the ground, was killed. Following the respected senator’s death, Heinz’s 20 years of public service was recognized by the naming of a college at Carnegie Mellon University after him and the founding of a history center that bears his name. Perhaps one of the highest honors bestowed upon the late senator was the re-naming of the Tinicum National Environmental Center, located a short, 15-minute drive from Naval Square. Heinz was a key player in the initial founding of the refuge in 1972. The John Heinz Wildlife Refuge at Tinicum is the perfect place to visit with family and friends. You can even take your dog along for the trip! Although the refuge is situated next to t...

A Curmudgeon's Guide to the Happiest Place on Earth

As I am shuffled through a dark, narrow tunnel by faceless attendants, my claustrophobia escalates from a minor issue to a big problem.    My two children, unnaturally calm husband, and myself are then gently transported in oversized seashells through yet another curving, dark tunnel featuring dancing images of Nemo and Dory. I manage to quell my rising panic attack. Welcome to “The Happiest Place on Earth”! If you are considering a family trip to the Walt Disney World (WDW) theme parks located in and around Orlando, Florida, read on. If, however, you expect a cheerful litany of helpful hints, think again. My impressions of the parks and the quality of Disney’s cuisine, lodging, and service are rendered with a gimlet eye: No detail escapes my hyper-vigilant worldview. I do admire Disney’s vision, and the organization is engaged in wonderful endeavors. But I would be remiss if I did not also point out the less sunny side of WDW. It IS a “small world,” after all, until ...

SouthGate Turns Traditional Korean Food on Its Head (in a Good Way)

SouthGate www.southgatephilly.com 1801 Lombard Street 215-560-8443 My earliest memory of eating in a Korean barbeque restaurant hails all the way back to 1992, in Pentagon City, Virginia, just outside of Washington, D.C. Each table had a built-in grill on which patrons cooked marinated, thinly sliced, tender beef. Numerous tasty vegetable sides calmed the palate. The food was so delicious that one hardly even noticed the bland, conservative décor. You had to wonder, however: am I eating in the lobby of an office tower, or a restaurant? Happily, the Korean cuisine-inspired gastropub SouthGate (1801 Lombard Street) boasts both a modern, hip atmosphere and an inventive menu. The long and narrow space that once housed Tangier bar and restaurant has been transformed: white and gray tiles cover the walls facing the bar, and muted, soft lighting lends a warm glow. The energy is upbeat and young without feeling pretentiously exclusive or manic.  Although many fried foo...
