Ticks are parasitic arachnids that live in grassy or wooded areas. People can unknowingly pick up ticks as they walk past bushes, plants and grass. Ticks can also be carried on a pet and then transferred to a human. According to the National Institutes of Health: “Ticks can be fairly large—about the size of a pencil eraser—or so small that they are almost impossible to see. Ticks can cause a variety of health conditions ranging from harmless to serious.” (more…)
Many people think acne affects only teenagers. On a daily basis, I encounter patients over the age of 20 who complain and ask: “Why am I still breaking out at my age? Shouldn’t I have outgrown acne?”
As acne is more prevalent in adolescents (affecting more than 85% of them), it has been miscategorized as an adolescence disease. It probably doesn’t help that most ads for acne target teens and young adults. However, in the physician’s office, the mean age of presentation for treatment is 24 years, with 10% of patients being between the ages of 35 and 44. (more…)

Pressure ulcers are breaks in the skin over boney areas, such as the heel, elbows and tailbone. They occur in people who are at special risk for skin breakdown, including:
• Patients with spinal cord injuries
• People who are bed-bound with advanced dementia or chronic debilitating neurologic disease like multiple sclerosis
• Individuals with acute illness requiring stays in the intensive care unit (more…)
Did you know that during the normal course of a day, you will lose between 50 and 100 hairs? This is nothing to be concerned about — it’s just nature’s way of replacing old hair with new. Other mammals have growing and shedding seasons, but human beings consistently grow and shed hair on a daily basis throughout life. But what happens when you lose more hair than is typical?
For many of us pet owners, our animal friends provide comfort and companionship. It is often said that we begin to resemble our pets and share common features. This may or may not be true; however, one thing that is becoming evident is that pet owners and their pets can share diseases. Such shared diseases are called zoonoses.
Over the last 10 years, there has been an increase in skin problems in both pets and their owners attributed to what the media has hyped as the “flesh eating bacteria/super bug,” or methicillin-resistant Staphylococcus aureus (MRSA). MRSA is a form of bacteria that is resistant to traditional antibiotics. MRSA infection and colonization have been reported in horses, dogs, cats, birds and cows, just to name a few. Still, it is important to note that humans are more likely to acquire MRSA from other humans.
While MRSA may be common and harmless in healthy people and their pets, there is a subset of the population that is more susceptible to these infections: the very young, who still have an immature immune system; the elderly, with declining immune function; and people who have open wounds or sores. Patients on various treatments like chemotherapy or antibiotic therapy also may have decreased immune activity.
The human hands are the most common area for exposure to MRSA because they are the most likely sites to be bitten by an animal. Cats typically pose more of a risk for bite infections because of their very sharp, pointed teeth, which could puncture the joints of the hands. Dogs tend to cause more traumatic destruction of tissue.
Pets usually acquire a MRSA infection from someone who has brought the bacteria home. Once a pet is infected, it could easily transfer the bacteria to additional human beings, such as an individual returning from the hospital or child with a chronic medical problem.
The best way to prevent this kind of transmission to and from your pet is hand washing. It is also important to cover all wounds with bandages. If you develop a wound about the size of a quarter or bigger, prompt medical attention is important, especially if you also have a fever.
A few other things to keep in mind:
• Cat bites typically cause deep tissue wounds that should be washed immediately, covered in antibiotic ointment, bandaged and watched for infection.
• With a dog bite, medical attention may be necessary to evaluate the risk of rabies.
• With pet bites, if the patient is a carrier of Staph. aureus, his or her own bacteria may be lodged deeper, causing an infection. Similarly, a staph infection from one’s own bacteria could occur if it is introduced into a vulnerable location due to a bite or scratch wound, even if the pet is not infected.
• In households where people suffer from serial MRSA infections, pets should be swabbed (tested) and treated when necessary by their vets. Pets may shed the bacteria on their own, but can be treated with a simple nasal antibacterial cream.
So, next time, think twice before kissing your pet!

Nasal allergy symptoms (rhinitis) and asthma caused by allergens that are inhaled usually have seasonal patterns. While symptoms from various pollens occur in the spring, summer or late summer/fall, nasal allergy symptoms in fall and winter are due mainly to indoor inhalants and also usually seasonal. But in the case of indoor allergens, this seasonal pattern is the result of spending more time indoors in these months, with the windows closed and heat on, leading to both increased exposure times and increased levels of indoor allergens.
Dust mites—microscopic insect critters that live in our bedding—are the most important culprit among the indoor allergens causing allergic disease. Our pillows and mattresses are loaded with them. When you buy a new mattress that weighs, say, 100 pounds, it will weigh 102 pounds within a couple of years. That extra 2 pounds are from the accumulation of living and dead dust mites and their droppings. Fortunately, dust mites do not bite, though in addition to their role in causing nasal allergy and asthma, they probably also contribute to flares of eczema in certain patients.
The diet of a mite consists mainly of human skin scales, of which we shed a lot in the course of a day. This is why they love our bedding.
The life cycle of dust mites is related to humidity. They love the humid days of summer and proliferate wildly. Then, when the heat goes on indoors in autumn, the humidity falls and they die off, leaving additional particulate matter to breath in.
If you want to read some of the scientific research on dust mites, Google the name “Thomas Platts-Mills,” who is a world expert on mites and gives very entertaining lectures on the subject.
There is no way to know if one is allergic to dust mites without being tested. If you tested positive to “house dust” years ago (a test most allergists don’t do anymore), you should be tested again. Since house dust is a mixture of dust mites, animal dander, insect material and other dusts, allergy to any of these components would have resulted in a positive house dust test. Today, we test for the individual components of house dust.
1. The treatment for dust mite allergy is, first and foremost, avoidance.
Bedding – Various companies market breathable covers that seal the bedding. Mite covers have even been shown to reduce the risk of developing asthma for children born into families with a history of allergic disease.
Humidity – The use of humidifiers in most houses in winter is not recommended, as it encourages mite growth. Optimal humidity in the home of someone with respiratory illness is in the 30% to 40% range; most homes are within that range or higher in winter. If you are not sure, you can measure it with a hygrometer.
2. The second line of treatment is medication for the symptoms of rhinitis, asthma or eczema. These include various combinations of prescription and over-the-counter medications, including pills, nasal sprays, eye drops and, in the case of eczema, creams and ointments. Antihistamines (ocular and oral) are the only medications for rhinitis that are available over the counter without a prescription. Any over-the-counter medications for asthma should be avoided, particularly Primatene, which is not very safe.
3. For patients who do not respond sufficiently to the above measures, or those wishing to reduce their use of medications, immunotherapy (allergy injections) might be in order.
I hope your holiday season is happy, and that you can avoid the sneezin’ and wheezin’!
