When the Bugs Aren’t Real

by James Hubbard, M.D., M.P.H. I never heard of this in medical school, so when I saw my first patient with delusional parasitosis, I was quite bewildered. Here sat a well-dressed, anxious looking guy, scratching all over, who said he scabies and handed me the proof in a tissue. It was a flake of skin. “And look, Doc. See the bites.” I looked and saw where he’d been scratching—digging and clawing actually—into his skin. But no bugs of any sort. […]

Is It Really Scabies? Felt-Tip Markers and Other Diagnostic Tricks

Is it a scabies rash? by James Hubbard, M.D., M.P.H. The seven-year itch they used to call it, and if you’ve ever had it, you know the scabies rash itches like crazy—even worse at night. As with head lice, I see more scabies cases when school starts back. It can also become a problem for shelters, nursing homes, even hospitals.

For the umpteenth time, no one—not the teacher nor the principle nor the doctor—thinks you are. It’s not a question of cleanliness. […]

How to Disinfect Water

The Russian River in Alaska. by James Hubbard, M.D., M.P.H. You can’t count on water anymore. No matter how pristine looking, a mountain stream is full of parasites, such as giardia from animal feces. Pond water, even rainwater, is loaded with bacteria just waiting to make you deathly ill. But what if that’s all there is? It’s relatively simple to disinfect water manually so it becomes drinkable. […]
