Ringworm is one of the most common and widespread childhood maladies. Deceptive in its naming, ringworm is no parasite but rather a fairly mild, though atrociously itchy, fungal skin infection that affects 300 million people worldwide. An infection with the contagious Tinea capitis fungus is usually summarily dismissed by means of antifungal medications, but for decades prior to the discovery of such cures in the 1950s, infections with ringworm and other species of fungus were as intractable and as challenging as their bacterial counterparts. The mid-twentieth century, as modern an era as it seems, marked the early days of effective antimicrobial treatments, and though practical pharmaceuticals for bacterial, viral, and fungal afflictions were on the horizon, they were still far from universally available.
The cells of our immune system are the guardians of the human body, forever contending with various unwelcome intruders from viruses to drugs to lowly yet painful splinters. They are as industrious as they are indispensable.
The plague is back, and this time it’s not thanks to far-voyaging ships or caravans traversing some distant trade routes, but to corn. This disease, caused by one of man’s oldest bacterial foes, Yersinia pestis, and spread by flea-infested rodents, is often overlooked in modern times in favor of more headline-grabbing epidemics like Ebola, HIV, and antibiotic-resistant STDs. But the plague has always kept close quarters with mankind and continues to surprise us with its adaptability.
Laissez les bons temps rouler! Tomorrow is the final and momentous hurrah of the Carnival season, which culminates with Mardi Gras, otherwise known as Fat Tuesday. In New Orleans, the city I call home, Carnival is a season of festivities, decadence, and tradition, one that is celebrated amongst neighbours and visitors alike. Our revelry is an egalitarian one – everyone is welcome to come witness and participate in Carnival. But, for over a century, just a couple of hours away from the Crescent City, there lived a community of exiles, quarantined and barred from society, who were forced to forge their own Mardi Gras traditions. In honor of the biggest party of the year, I’m republishing my article on the celebration of Mardi Gras at one of America’s last leper colonies, just a few hours up the Mississippi river in Carville, Louisiana.
The measles outbreak emerging from “the happiest place on Earth” in Anaheim, California, is grabbing headlines and provoking conversation in the media regarding how best to appeal to parents opposed to vaccines.
Using clear facts and appealing to common logic has failed, repeatedly. Blaming and shaming only seem to provoke heel-in-the-sand reactions and encourage retreat. So how does one persuasively sway opinion and convince the skeptics of the safety and utility of vaccinating against preventable diseases?
Abracadabra! Many of us are familiar with this mystical incantation. Its arcane staccato and euphonious intonation has become deeply ingrained in our language through the word’s use as a magical catchphrase. The hex was, in my childhood experience, rather useless when it came to opening locked cabinets and provoking instantaneous transformations; nothing was conjured and very little materialized except for my own disappointment. But millennia past, this word was held in reverence, and it was used for a whole other purpose altogether. Abracadabra was not a silly-sounding piece of magician’s gibberish, but the “most famous of the ancient charms or talismans employed in medicine” and a powerful invocation against a very specific and very dangerous curse: malaria.
In March of 1942, a young woman was dying of sepsis in a New Haven hospital. In just one day, she would be miraculously revived by a newly discovered experimental drug, seemingly by “black magic” as one consulting physician would mutter. The woman’s full recovery with the new antibiotic known as penicillin was the very first occasion of its usage in the United States and would jump-start the pharmaceutical industry’s interest in and manufacture of the drug (1).
Tensions can run high when living with roommates. Quibbles over dishes, the rent and utilities, and even questionable hygiene practices can inflame tempers and sabotage relationships, leaving passive-aggressive notes and broken homes in their wake. There are many ways of managing a good home life within a shared household of semi-strangers, but we’ll save that for another time in another column. This is about a roommate dispute gone totally to the worms.
The Hajj, the pilgrimage to Mecca by millions of Muslims from around the world, is one of the largest gatherings of man on the face of the earth. This annual event took place just last month with relatively little fanfare from the news media, which is, from an epidemiological standpoint, a very good thing. Every year, public health officials wring their hands at the thought of possible outbreaks caused by the global pathogen du jour capitalizing upon the convergence of millions of worshipers in the Saudi Arabian desert. SARS stole the headlines in 2009, Middle Eastern Respiratory Virus or MERS had it last year, and Ebola seemed a likely contender for this calendar year.
Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, continues to make inroads in the United States and physicians are both unprepared to diagnose and under equipped to treat cases of the disease in their patients.
Chagas is a rare disease in the United States and has typically been associated with immigration from Central and South America, where the disease is endemic. The dynamics of the disease are changing, however, and strong evidence continues to emerge indicating that local infection is occurring among the American population, particularly in the southern states.
