The "Yearly Physical"

"I'm going to the doctor next week for my yearly physical." So normal. Of course you are. Everyone should do that. But the concept of a yearly examination of one's whole body to see if everything checks out fine is a relatively new invention and whether or not it is necessary is a very controversial question. I just read an article by Abraham Verghese, an internist and champion of physical diagnosis, professor at Stanford University, inspired writer, about the history of the physical exam. The idea that physicians could know more about a person than he or she could know about him or herself has only gained traction in the last century and comes partly from the invention of gadgets such as the stethoscope, the reflex hammer and the blood pressure cuff which reveal truths only to those of us skilled in their use. Enthusiasm for these has waned a bit as we have become enamored of our ability to see the shadows made by bones and such during an onslaught of elec

Preventing Cervical Cancer in Tanzania

I visited Tanzania again this summer, once again helping a group of amazing University of California, Irvine medical students with their summer not-a-vacation trip to teach bedside ultrasound and do other research projects.  One of the projects this year sprung out of a request by a doctor we have worked with on Ukerewe Island. The island he serves is rural, primarily supported by fishing, and has a high rate of sexually transmitted diseases due to fishermen visiting prostitutes on the mainland and bringing home infections to their wives and girlfriends. This translates to high rates of HIV infection, pelvic inflammatory disease and the spectrum of disease caused by human papillomavirus (HPV). HPV can cause genital warts, which are only mildly distressing, but it can also set in motion cellular changes of the cervix that can lead to cervical cancer. Tanzania has a distressingly high incidence and death rate from cervical cancer and this Tanzanian physician asked one of the students

My thyroid nodule

About 4 years ago I was examining my neck and discovered a nodule in the right side of my thyroid gland. I was examining my neck because I very rarely see a doctor and figured that I should at least cursorily examine myself to see if I could find anything of interest. My heart sounded fine, my lungs were excellent, weight was just right, pulse was nice and low, liver and spleen were fine, skin was slightly sun damaged but basically OK, blood pressure was a tad high and there was a small but definite lump in the right side of my neck. Since I have a portable ultrasound, I looked at my thyroid nodule and found it to be about 1.8 cm, with some internal calcifications and a bright capsule. It was slightly darker than the surrounding thyroid tissue and had a few visible blood vessels. I read about thyroid nodules and found that: 1. They are being noticed much more frequently because of increased use of CT scanning and ultrasound imaging. 2. They are very common. Nearly half of peo
