When listening with a stethoscope to a patient's heart, one sometimes hears a deviation from the typical "lub-dub" rhythm. Sometimes the "dub" is too loud, or the "lub" too soft. There might be a rubbing sound, or a harsh blowing sound. By interpreting subtle characteristics such as the location, pitch, and timing of these sounds, one can sometimes diagnose things like a diseased heart valve or congestive heart failure.

A friend was working an overnight shift in the ER for one of her mandatory rotations, so I popped in to observe. The ER was surprisingly quiet. A classmate was also observing that night, and like me, he was standing around, bored. We spotted an electrocardiogram (EKG) readout lying on a desk where a resident was working, and we asked him ...

I attended a talk by the Dean of Admissions of one of the most competitive medical schools nationwide. The topic was primary care and community health. He talked at length about how not enough medical students were entering primary care. He put up some graphs showing that the most lucrative specialties tend to be the most competitive ones, with primary care among the lowest-paying and least-competitive. He said that medical ...

Paradoxically, some parts of our body work best when they fail under stress.
An illustrative story from my freshman year of college.
I decided to buy a wheelie chair for my (miniscule) dorm room from a student who lived 1.5 miles away. How could I transport the chair across campus when I didn't have a car?
I didn't feel like wasting an hour walking there and then walking the chair back. Instead, I ...

Years ago, I spotted an acquaintance I hadn't seen in a while. The conversation was odd. A few times, I would ask a question and he would begin to respond, only to trail off into silence and stare blankly into space. He would remain frozen until the moment I said something else, whereupon he would act normally. He seemed completely oblivious to the fact that he had trailed off and ...

I recently learned the sorry news that my childhood pediatrician has died. Not only was he my pediatrician, but he was also my father's pediatrician. Our family became rather close to him over the years.
He came from a different generation of doctors, one that made house calls, that served in wars abroad, and that learned how to diagnose patients in the days before MRIs and CT scans. Even though I ...

I was skeptical when a doctor casually mentioned that 2% of all pregnancies are ectopic pregnancies (in which the fertilized egg is implanted somewhere other than the uterus, usually the fallopian tube). Without treatment, a common outcome is fallopian tube rupture, which jeopardizes the life of the mother. It is a serious medical concern. I shot a confused look at a fellow first-year medical student. Two percent? It seemed way ...

There is a healthy debate over whether a lab that created an extremely infectious version of influenza ought to publish the genetic sequence. The debate speaks to a larger problem: sometimes, medical advances do the world a disservice. The medical field could use some soul-searching, just as physicists did in the wake of the Manhattan Project.
A few years ago, I read a neat research finding. In a pregnant woman, ...

Some medical schools have altered their admissions process by replacing the traditional applicant interview with the Multiple-Mini Interview (MMI). MMI resembles speed-dating: applicants rotate through numerous interview stations, where they act out scenarios and solve puzzles, sometimes alone and sometimes in groups. A July New York Times article presented a good overview of MMI, as implemented by Virginia Tech Carillon.
As you might expect, schools that have adopted MMI (UCLA ...

The milestone of the world's population reaching 7 billion is a fitting time to reflect upon life expectancy. Life expectancy is a rough marker of humanity and medicine's progress in the age-old battle to attain old age.
Those born in the US this year are expected to live until 78.37 years of age if current mortality rates persist. This puts us at a sobering 50th in the world.
How long is ...
