Athlete’s foot is the popular name for a fungal infection that affects the skin on the soles and between the toes of the feet. It is one of the most common dermatological problems caused by fungi. Here’s why it develops and what you can do about it.
The term “athlete’s foot” was coined by the New York physician Charles Pabst (1888-1971), who encountered many cases of this infection among “sandwich men”, very common at that time in the streets of large cities. Also referred to as "athletes", these walking billboards carried advertising on their chest and back, walking long distances wearing sturdy boots as protection against bad weather. It was those strong, tightly laced boots that created conditions conducive to the spread of fungal infections of the feet. The name became popular and, since the infection is common among athletes, it continues to be used today — although almost nobody remembers its origins. Read More
Acne, particularly common in teenagers, is one of the world’s most common skin disorders. Although it results in a wide range of lesions, acne, even if untreated, is often benign. However, sequelae in the form of scars may persist for life.
Acne is such a common problem that we often take it for granted as a normal physiological phenomenon. Some 85% of adolescents experience, to a greater or lesser degree, acne lesions of various types: comedones (blackheads and whiteheads), papules (pinheads), pustules (infected pimples) and nodules (larger, raised and often painful lesions). Fortunately, very effective treatments are available nowadays and most cases resolve in time. But if the lesions become scars, these can persist for life. Read More
We say that someone’s skin is atopic when it has a tendency to develop atopic dermatitis. It's that simple. Atopic dermatitis is the most common skin disease in children. It not only affects the quality of life of the child, but also of the family. Leaving aside correct diagnosis and treatment by a dermatologist, there is a great deal of controversy about other issues affecting these children, such as skincare, clothing, bathing, etc.
Atopic dermatitis (or atopic eczema) is a very common skin disease, which affects in the western world one out of three babies during the first years of life. The main symptom is itching. While there is no single known cause, clinical manifestations enable the paediatrician or dermatologist to make the correct diagnosis (there is a significant hereditary component). These children are at increased risk of developing asthma, urticaria and allergic rhinitis. The disease is not stable, but evolves in stages marked by flare-ups (typically occurring in winter) and by dormant periods. Read More
The fever blisters or cold sores that typically appear on the lips are manifestations of the herpes virus, which can also affect the skin elsewhere. Herpes is an extremely common viral infection and, although rarely serious, it causes major discomfort and is also anti-aesthetic. Even more bothersome is the fact that cold sores usually recur over a lifetime.
Herpes labialis is an infection caused by the herpes simplex virus, whose symptoms are observed mainly in the skin and the mucous membranes. It is usually acquired in childhood, so by adulthood most individuals have had contact with the virus. Cold sores on the lips are, in fact, just one of the manifestations (although the most common by far) of herpes simplex infection; the virus can also cause eye problems, affect the inside the mouth or the genitals and even cause more serious problems (meningitis).
