In Indiana, the number of Lyme disease cases has increased 82 percent, rising from 34 cases in 2005 to 62 in 2009, according to the Indiana State Department of Health.
In Tippecanoe County, the number of cases investigated by public health nurses rose 90 percent from 1 case in 2005 to 10 in 2010, according to the county health department.
The cause for the increase is unknown. Possible theories range from an upswing in the number of cases reported to a higher percentage of ticks that are infected with the bacterium, according to health officials.
Northwest Indiana also saw a possible surge in Lyme disease cases. The Associated Press recently reported that nearly 18 people said they had the disease at a town hall meeting in Ogden Dunes, a northwestern Indiana town along Lake Michigan.
Gibb said that a surge in that area is not surprising. "Within Indiana we find it most in the northwest," he said. "That whole area (northwest Indiana, northeast Illinois and southern Wisconsin) has been traditionally a hot spot for deer; as a result deer ticks and as a result of that Lyme disease."
The black-legged tick is most likely being transported south and east within the state on the backs of deer - its preferred host, especially as the deer population increases, Gibb said.
gives pest management professionals (PMPs) a first-hand look at how to use aerosol products.
Featuring Dr. Phil Koehler, professor of urban entomology at the University of Florida, the video follows a back-to-the-basics approach to six different categories of aerosols.
Using simple explanations and how-to demonstrations, Dr. Koehler goes step-by-step through the use of:
• Surface sprays
• Space sprays
• Crack-and-crevice treatments
• Jet sprays • Metered dispensers
• Total release aerosols
“Figuring out which product to use in which situation can be confusing, so the video is a good refresher for pest management professionals,” said Catherine Bernard, product manager for FMC. “We wanted to demonstrate appropriate uses of aerosol products, as well as explain how they can be used together in a protocol.”
University of Pennsylvania neuroscientist Dr. Wenqin Luo places the blame for phantom itch on memories of an itchy past. Thinking about bugs, she explains, might prompt memories of previous experiences – “itchy associations.”
Why, then, doesn’t thinking about injuries prompt our bodies to feel phantom pains?
Dr. Luo offers the following theory: “Compared with itch, pain is a serious protective mechanism that triggers avoidance behavior. Thus, the threshold to trigger a pain sensation may be much higher than that of itch.”
Basically: If our brains registered pain (a danger) as easily as they do itch (an annoyance), our bodies would be sent into constant states of false alarm.
Dr. Glenn J. Giesler, Jr., a neuroscientist from the University of Minnesota offers a slightly different guess as to the phantom itch culprit: Maybe our skin always experiences the tiny sensations capable of causing light itch – but we only notice them when we’ve already got itch (or its creepy crawly causes) on the brain.
“It is amazing to me how easy it is to induce itch in others,” says Giesler. “Whenever I give a talk on the topic, I am amused at the percentage of people in the audience who start scratching.”
“Perhaps,” he guesses, “the threshold for sensation of itch is lowered by thinking about it.”
