What Use Is the Physical Examination in Current Medical Practice?
A very interesting, quite scholarly perspective appeared in the NEJM last month called, “Strategies to Reinvigorate the Bedside Clinical Encounter.” Drawing plenty of attention on social media, it elicited the usual hand-wringing from clinicians who bemoaned the way modern medicine has evolved — away from direct care of patients and toward an ever-expanding reliance on […]

Dengue, Malaria, HIV Cure, and Others — First Cold Snap of the Winter ID Link-o-Rama
Absolutely brutal temperatures arrived up here in Boston over the past week, just in time for the peak holiday season, and we’ve even had a dusting of snow. Here’s proof, in case you don’t believe me. Of course, this isn’t stopping teenage boys from walking to high school in just shorts and sweatshirt hoodies, which […]

ID Things to Be Grateful for — 2025 Edition
Looking back on these annual Thanksgiving posts, I notice an odd pattern: every few years, the intro turns into a kind of apology. As in, Yes, I know the title sounds upbeat, please don’t attack me. The world feels heavy, the ID bad news scrolls by, and there I am writing about gratitude. A colleague […]

When AI Gets the Medical Advice Wrong — and Right
A journalist recently reached out to ask about the shingles vaccine. We mostly talked through the usual topics — how common shingles is, why the vaccine works so well, and side effects. Plus, the whole topic of zoster vaccination has been much in the news recently given studies associating receipt of the vaccine with a […]

Hot Takes from IDWeek: CDC, COVID, and Two Doses of Dalbavancin
Every so often, you sit down for what’s supposed to be a lighthearted conversation and end up somewhere not just fun, but deeply enjoyable and even profound. That’s what happened when I joined my friends and ID colleagues Drs. Buddy Creech (Vanderbilt, pediatric ID) and Mati Hlatshwayo Davis (Washington University, public health expert) for the […]

Favorite ID Fellow Consults: Johns Hopkins Edition
Just back from a visit to the Infectious Diseases Division at Johns Hopkins, thanks to the kind invitation of current ID chief Dr. Amita Gupta and her predecessor, Dr. David Thomas. On a personal note, this visit was only a few decades late. When I applied to medical school, Hopkins never invited me to interview […]

Two Covid Vaccine Studies — One Actionable, the Other Not So Much
As we await the results of placebo-controlled Covid-19 vaccine studies, what are we clinicians to do when our patients ask us whether they should get a booster this fall? What once was a no-brainer in the early days of limited immunity to the virus — and the spectacular results of the first placebo-controlled trials — […]

What a Difference a Year Makes — with Bonus Halloween Video
At last year’s IDWeek — the annual meeting of the Infectious Diseases Society of America — a group of us veterans in the HIV/ID world wrapped up a busy day of symposia, abstracts, and posters with a lively dinner in Los Angeles. What do I mean by veterans? If you started your ID training before […]

Another Bad Week for the CDC, and a Personal Note
On Friday night, news broke that more than a thousand CDC staff received layoff notices — including people who track measles outbreaks, analyze data to craft policy, monitor employee safety, and, remarkably, recent Epidemic Intelligence Service (EIS) fellows (the early-career epidemiologists who often show up first when something alarming appears). Now, nearly a week later, […]

DOTS: Optimism Around a “Negative” Dalbavancin Trial
The DOTS randomized clinical trial of dalbavancin versus standard-of-care for Staph aureus bacteremia (SAB) just landed in JAMA, where it undoubtedly will be featured in numerous ID, hospitalist, and medical resident journal clubs over the next several months. Proof: one of our great second-year ID fellows tagged it immediately for his journal club literally the […]
