“I hate needles.” Patients say this to me everyday. When you think about it, who “likes” needles?
Skin biopsies are relatively painless, but they still involve the dreaded needle and always leave scars. The trouble is we dermatologists cannot guarantee that a mole isn’t skin cancer without sending a biopsy for pathology. That is, until now.
Although it is not available in clinic yet, an almost incredible new innovation might allow us to determine if a mole is cancerous by testing the DNA of the mole. It sounds like it’s from an episode of CSI, but it’s real.
Melanomas have DNA (messager-RNA to be exact, but it’s a little complicated) that differentiate them from normal moles, so testing the mole for melanoma requires only a tiny sample of skin. Fortunately, no needles are needed — in fact, no sharp objects are necessary at all. Read more »

The answer might seem obvious, but I get this question often in clinic. In particular, patients want to know if genital herpes is contagious even if they or their partner is not having an outbreak.
The answer is yes. Genital herpes is a common sexually transmitted disease and is highly contagious. Although the risk of infecting someone else is much higher if you’re having an outbreak, it is still possible to transmit the virus, called HSV, even if you have no symptoms. About 1 in every 6 adults has genital herpes.
Once you have herpes, there is way to cure it. It is common to have recurring outbreaks especially in the first year, but in most people these lessen over time.
The only way to ensure you won’t get herpes is to abstain from sexual contact or to be in a monogamous relationship with a partner who is not infected. Wearing a condom can reduce the chances of infection, but it’s still possible to be transmitted. Taking anti-herpes medication such as acyclovir can reduce the amount of virus and minimize the risk of transmitting it.
April is STD awareness month. If you’re thinking you might need to get tested, then you need to get tested.

Seems like I’ve been on a real run of chest pain patients lately. Which is fine — it’s part of the gig. I did have a very interesting pair the other night. They were seen in sequence, right next to one another, in room 7 and room 8. They were both totally healthy women in their mid-fifties. And they were both over-the-edge, crazy, crawling-out-of-the-gurney anxious.
Anxiety is an awful red herring in the work-up of chest pain. People who are having an anxiety attack often if not always manifest some chest pain (pressure, tightness, whatever) as a prominent symptom of their anxiety. On the other hand, someone having a heart attack who is experiencing chest pain will also be anxious — and for good reason! Read more »
