Oh, joy! Another riveting tale from the world of patch testing, this time starring the ever-so-versatile Ethylenediamine dihydrochloride (EDD). It’s not just a mouthful to say, but also a skinful of trouble for some, as it’s a known allergen. But don’t worry, the intrepid researchers of northeastern Italy are on the case, armed with 25 years of data and a baseline series that’s probably more consistent than your favorite TV show.

Between 1996 and 2021, a whopping 30,629 patients suspected of allergic contact dermatitis were slapped with patches to see if EDD made their skin throw a fit. And guess what? The overall prevalence of this sensitization was a whopping 1.29%. Hold the press; that’s almost as common as finding someone who can’t stand pineapple on pizza.

But wait, there’s a plot twist! The prevalence is decreasing over time. That’s right, folks, we’re now below the 1% mark in recent years. Maybe it’s the Italian air, or perhaps people are just getting tougher skin. And if you’re from Pordenone, congrats! Your area seems to be a magical protective bubble against EDD sensitization.

As for jobs, it seems like EDD doesn’t discriminate based on your occupation. Whether you’re a banker or a baker, your risk is the same. But age? That’s a different story. If you’re between 26-35, watch out – you might be slightly more likely to react to EDD. And if you’re already sensitive to the paraben mix or epoxy resin, well, you might as well buy a lottery ticket because your odds of reacting to EDD are through the roof.

In conclusion, the researchers suggest it’s time to update the Triveneto baseline series because, you know, science never sleeps and neither do skin allergens. So, let’s give a slow clap for the decline in EDD sensitization and the diligent patch testers of Italy. Bravissimo!
