You may have noticed a number of headlines referencing the “Tree Man” from Bangladesh with claims he is “cured” after 16 operations for his rare genetic disorder that transformed his hands and feet into bark-like warts and cutaneous horns.  

Also called Epidermodysplasia Verruciformis (EV), this debilitating, heritable condition is often referred to as “Tree Man Illness” or “Tree Man Syndrome.” Though it manifests throughout the body via innumerable abnormal growths on the skin, it is considered to be caused by a genetic impairment that triggers a defect in a person’s cell-mediated immunity.  

More than 200 cases have been reported since it was first described in 1922 by two dermatologists, hence, its other name “Lewandowsky Lutz Dysplasia.” (1) Most present in childhood...

Perhaps the strangest medical phenomenon discovered in recent years is a link between the lone star tick and an allergy to red meat.

The bite of a lone star tick exposes a person to a small carbohydrate called alpha-gal. In a handful of people, this exposure elicits an abnormal immune response that produces a type of antibody called IgE, which causes allergies. Because red meat also contains alpha-gal, people who have been sensitized to the carbohydrate from a tick bite can develop life-threatening anaphylaxis if they consume pork or beef.

Cow's milk allergies

Allergy to cow's milk is not well understood*. It is known that the phenomenon is more common in children than adults and that it generally goes away as a child grows up. As one might suspect in our age of hypochondria, parents who think their child has a milk allergy are far more common than parents who have a child with an actual milk allergy.

In an effort to understand how cow's milk allergies (CMA) form, an interdisciplinary team of scientists investigated if there is a link between certain kinds of sugars found in a mother's breast milk and the presence of CMA in her...
