Actinic keratosis

Actinic keratosis is a skin abrasion that appears as an uneven, scaly patch on your face, lips, ears, back of your hands, forearms, scalp and neck. The cause is frequent or intense exposure to ultraviolet (UV) rays, typically from the sun. An actinic keratosis, also known as solar keratosis, enlarges slowly and usually causes no signs or symptoms other than a patch or small spot on your skin. An actinic keratosis takes years to develop, usually first appearing in older adults. Many doctors consider an actinic keratosis to be precancerous because it can develop into skin cancer. You can reduce your risk of actinic keratosis by minimizing your sun exposure and protecting your skin from UV rays.

Allergic rash

Allergies are disorders of the immune system, whereby largely harmless substances (allergens) which come into contact with the body provoke excessive and unnecessary immune defence reactions.  A common result of such an allergic episode is an allergic rash which in severe cases can spread out over the entire body and require hospitalisation for treatment.  Common allergens that may cause allergic rash include medications, certain foods, insect bites and contact with certain plants.  Furthermore, so-called ‘contact allergies’ can cause allergic rash after a person has an extended period of contact with particular substances.  Common substances that trigger contact allergies are latex (eg. in rubber gloves), nickel (eg. in jewellery), perfumes and adhesives.  Sometimes contact allergies only arise after exposure to sunlight and are thus termed ‘photocontact allergies’.  It is possible to be tested for allergies in order to know what allergens to avoid.  This is done by applying small amounts of different known allergens to the skin in order to see which trigger an allergic rash (patch test).  Therapy of allergic rash usually involves administering medication that reduces the immune response to the allergen and avoidance of the allergen in daily life.

Bacterial skin infection

Bacteria can cause numerous types of skin infection, from relatively mild rashes to life-threatening tissue damage.  Several types of bacteria live on the skin and under normal circumstances do not cause any harm.  However, if these bacteria are able to enter the skin through wounds, bacterial skin infections can result.  The bacterial skin infection that then occurs depends on the type of bacteria and the location, depth and extent of infection.  Common signs of bacterial skin infection may include redness, blistering, tenderness, swelling and deep, open ulcerations.  It is important to treat bacterial skin infections promptly in order to prevent the infection from spreading.  Treatment of bacterial skin infections generally first involves the identification of the infecting bacteria, then disinfection of the affected skin area coupled with appropriate antibiotic therapy.

Chronic leg ulceration (ulcus cruris)

Chronic leg ulceration is a relatively common disorder, affecting approximately 1% of the middle-aged and elderly population.  Most commonly, chronic leg ulceration arises as a result of disturbed blood circulation, however it may also be caused by injury, diabetes or bacterial infection.  Some typical causes of underlying circulatory disorders that can lead to chronic leg ulceration include varicose veins, high blood pressure, deep vein thrombosis, heart disease or blood clotting disorders.  The location and character of chronic leg ulceration depends on the underlying cause.  For instance, if chronic leg ulceration results from a disturbance in circulation in the veins, the ulceration is often found below the knee and in the inner ankle region, is relatively painless (unless infected) and is associated with leg aching and swelling.  On the other hand, if the problem is poor circulation in the arteries, the ulceration is often found on the feet, heels or toes and is frequently painful, especially with elevated legs or sometimes while walking. Chronic leg ulceration resulting from diabetes is similar to that resulting from poor arterial circulation.  Treatment of chronic leg ulceration depends on the underlying cause and usually begins with conservative therapy such as making lifestyle changes. Keeping the wound clean and removing dead tissue is another essential aspect of treatment, along with treating any further infection that may arise.  In more serious cases of chronic leg ulceration, surgery may be required to restore the affected area.  No matter what treatment is used, handling not only the chronic leg ulceration itself, but its underlying cause is tantamount to therapy success.

Connective tissue disease

Connective tissue disease refers to a group of conditions that are usually severe and chronic (recurring and long-standing) in nature and are characterised by pathological changes in the connective tissues of the body.  In many cases, connective tissue diseases can affect several organs of the body, however in some less severe cases the skin may be the only area affected.  Connective tissue diseases often result from autoimmunity, whereby the body’s immune system mistakenly recognises part of the body as ‘foreign’ and therefore attacks it.  Some prominent connective tissue diseases include systemic lupus erythematosus, scleroderma, rheumatoid arthritis and dermatomyositis.  These diseases are each characterised by a typical array of symptoms (eg. butterfly-shaped rash across the nose and cheeks in systemic lupus erythematosus, tightening and hardening of the skin in scleroderma, joint pain and morning stiffness in rheumatoid arthritis, livid-red rash around the eyes and muscle weakness in the shoulders and hips in dermatomyositis) although some symptoms may overlap between diseases.  Treatment of connective tissue diseases usually involves anti-inflammatory and immune suppressive medication for the general disorder and regular monitoring and, if necessary, therapy of any secondary organ-related complications.
