Hello, I’m Neal Schultz pause And welcome to DermTV. This may be the season for itchy skin, but chances are if its your fingers that are itching, its not because theyre dry.
Most of the time, itchy fingers are caused by a condition called Dishydrosis and the itch it causes can really drive you crazy. And its not just itching that Dishydrosis causes You actually get little bumps on the bottom and sides of your fingers. And the bumps are actually tiny blisters. Dishydrosis literally means, bad sweating,.
And it used to be thought that these crazily itchy bumps were filled with sweat. Thats why it was named Dishydrosis. But the fluid isnt sweat its actually serum, which is the clear fluid in your blood. The most common cause of Dishydrosis is extreme stress, although not every outbreak can be linked directly.
To a stressful situation. on a personal note, i can tell you that Ive only experienced Dishydrosis once in my life. It was early in my medical training after a very stressful night of being up all night taking care of a lot of very sick patients. The next morning the dermatologist was making rounds and I showed him my hands, and he said,.
boy you must have had a really rough night. So. The itching and bumps both finally go away after a few days. As it gets better, there are these really interesting telltale little collars of dead flaky skin that peel off. Those tiny matchhead size collars of dead skin get larger. and then smaller. over a few days and are caused by.
The bubble of serum as it rises through the higher levels of the epidermis. Its like taking horizontal slices through a sphere starting tiny at the bottom, then getting larger, and finally smaller again. To treat the itching and bumps, topical cortisone creams and antiitch lotions with menthol are best.
If that doesnt stop the itch, cold water can usually give temporary relief, but never try to stop the itching with hot water. Even though hot water feels good and stops the itch, it also causes the itch to come back worse a few minutes later. After the itch and bumps are gone, the flaking skin can continue for a week. It can be camouflaged with a moisturizer,.
Leg Ulcers 7 Facts About Leg Ulcers You Must Know
Leg ulcers are common approximately 2% of adults will have a leg ulcer at some stage in their lives. Literally thousands of people develop a leg ulcer each year in the United Kingdom and many of those get more leg ulcers as the years go by. Despite the misery they cause, leg ulcers remain a neglected problem. I am going to tell you the 7 essential facts should you know about leg ulcers. Number 1 What is an ulcer? The medical definition of an ulcer is a break in the epithelium of a body surface or lining. Many of us will.
Be familiar with a mouth ulcer. this is a break in the cell lining the mouth. it can be caused by an injury such as biting the inside of the mouth by accident. Well if the skin breaks down anywhere on the body it is called an ulcer. If the ulcer is on the leg and has been present for more than 6 weeks it is called a chronic leg ulcer. Number 2 What causes a leg ulcer? Four out of 5 ulcers that’s 80% are caused by a problem with the leg vein pump and they are called venous ulcers. The leg vein pump is the mechanism.
By which blood flows out of the leg back to the heart. so problems with the deep veins such as obstruction from a deep vein thrombosis, superficial vein reflux or perforator vein problems can cause venous leg ulcers. The leg vein pump depends mainly on good ankle movement, good calf muscles and healthy leg veins. A minority of leg ulcers about 15% are caused by problems in the arteries that carry blood into the leg. About 95% of venous leg ulcers can be correctly identified by their appearance, by checking for pulses in.
The feet and by checking sensation. as most leg ulcers are venous that’s what i am going to concentrate on. Number 3 Where on the leg do you get venous ulcers? Well venous leg ulcers appear on the lower part of the leg usually just about the ankle. Often, there are varicose veins or thread veins around the ulcer and the leg is usually swollen. The skin is often thickened and discoloured by varicose eczema which many actually develop many months or years before the ulcer as a warning sign that the vein circulation is.
Not normal. number 4 who gets a venous ulcer? well these ulcers affect people who have deep vein problems, usually from a past deep vein thrombosis (DVT), people who have superficial venous disease or those with ankle mobility problems. Leg ulcers are more common as we get older. Number 5 How do you treat venous ulcers? The aim of treatment is to get the ulcer healed as quickly as possible. This usually means graduated compression either with bandages or compression stockings. In most cases, antibiotics, creams and ointments.
Are not necessary. once the ulcer is healed it is very important to identify any problems with the superficial veins or perforator veins and that these are treated to reduce the risk of another ulcer. This means getting a full assessment with a duplex ultrasound scan. Number 6 Can you cure a leg ulcer? Well this is controversial. Some would say that if the problem is only in the superficial veins, the veins under the skin, or in the perforator veins that connect these superficial veins to the deep veins, then the ulcer can be cured.
While there is good evidence that such treatment will greatly reduce the risks of getting another leg ulcer, if the skin has been very damaged and the ulcer has healed with a lot of scarring, this area of the leg may remain vulnerable and a trivial knock or injury might cause another skin breakdown even though the vein abnormality has been completely eradicated. Number 7 How can we avoid leg ulcers? Well there are 3 things I would suggest. Firstly, if you are unfortunate enough to suffer a deep vein thrombosis (DVT), it should be treated.
Promptly to limit the damage to the deep veins. unfortunately, damage to the deep veins cannot be reliably reversed by surgery. So, prompt treatment with anticoagulants blood thinning medication reduces the extent of the clot and the damage to the deep veins. Secondly, if you have had a DVT, you should consider wearing good quality medical grade compression socks some studies suggest that doing so may reduce the risk of leg ulcers after a big DVT. Thirdly, if you have superficial vein reflux have it treated early to reduce.
