    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

    Surviving melanoma but failing to learn

    5 Sep Surviving melanoma but failing to learn

    We tend to forget, for better and for worse. Or, put another way, we repeatedly trip on the same stone. Different studies show that patients who have had melanoma do not protect themselves from the sun as they should and eventually return to their old habits.

     

    According to the European Cancer Observatory, nearly 68,000 Europeans are annually diagnosed with melanoma. Patients who have had this aggressive type of skin cancer are at higher risk than the rest of the population. For this reason, they are supposed to stop sunbathing and to double sunscreen use, even when just going out for a walk. However, it seems that they eventually leave off these practices, with some even confessing that, by the second or third year, they have been sunburned at least once! Read More

    Microbiota – the skin’s “flora”

    31 Aug Microbiota - the skin’s "flora"

    Our skin is a balanced ecosystem. Since it was colonized by billions of bacteria, viruses, fungi and mites at the dawn of the evolution of hominids, many species of microorganisms have lived in symbiosis with our skin mantle cells. Science’s efforts to identify our colonizers have revealed how essential these microorganisms are for the health of our skin. The most natural way to healthy skin is to help maintain the balance between all these microorganisms.

     

    Although it may be difficult to credit, only 10% of the cells of the body’s skin, intestines and mucous membranes are human. Most of them are of microscopic organisms that belong to the microbiota, the set of all foreign microbes that live in our body, especially in the digestive organs and the skin. For example, each square centimetre of human skin contains approximately one million microorganisms from a hundred different species. Together these form the skin’s microbiota (traditionally called the skin’s "flora”). This ecosystem is comparable in complexity to any other system in the Earth’s mantle. Today we know that our skin has hosted these microorganisms over thousands of years of evolution and that it is the symbiosis between our own cells and these tiny guests which helps the skin to perform its primary function of acting as a protective physical barrier.

    When smelling bad is not a matter of hygiene

    28 Aug When smelling bad is not a matter of hygiene

    An offensive body odour may not be the result of a lack of hygiene. Bromhidrosis is a disorder affecting both men and women and usually associated with secretions by the apocrine sweat glands located in the armpits, pubis, perineum and navel, behind the ears and in the folds under the breast. It is a chronic but treatable disorder.

     

    Persons affected by bromhidrosis do not perspire more; rather, their apocrine glands produce sweat containing ceramides that are different to those of the rest of the population. When broken down by the skin’s bacteria, a strong odour is the result. This odour, which is often described as pungent, musty or sour, cannot be dissumulated. The condition is believed to be genetic in origin, but may also be caused by a metabolic disorder such as diabetes, by thyroid or adrenal gland alterations or by certain drugs. In addition, certain foods, such as onions, garlic and spices, and also tobacco use and alcohol consumption, can aggravate the condition. Read More
