Mohs surgery done on a 72 year-old patient's nose
Maybe you have heard of someone you know getting scabies, or maybe you have even had them yourself. If so, then you are probably well aware of just how miserable of a condition it is to deal with. Scabies is caused by a tiny mite that has infested humans for at least 2,500 years. The disease is often hard to detect, and causes a fiercely, itchy skin condition. In Disney’s Pirates of the Caribbean: Dead Men Tell No Tales, Jack Sparrow referred to scabies as the "incurable itch", and if you have ever had them then you know that the itch does in fact seem "incurable". Dermatologists estimate that more than 300 million cases of scabies occur worldwide each year. Scabies is most common in those who have close physical contact with others, particularly children, mothers of young children, sexually active young adults, and elderly people in nursing homes. The condition can strike anyone of any race or age, regardless of personal hygiene. The good news is that with better detection methods and treatments at our disposal, scabies does not need to cause more than temporary distress.
So how do you get scabies?
The microscopic mite that causes scabies can barely be seen by the human eye. The eight-legged mite burrows in the skin and within several weeks, the patient develops an allergic reaction that causes severe itching; often intense enough to keep sufferers awake all night long! Human scabies is almost always caught from another person by close contact. It could be a child, friend, or another family member. Everyone is susceptible. Scabies is not a condition isolated to low income families or neglected children, although, it is more often seen in crowded living conditions with poor hygiene. Why is this? The mites are attracted to warmth and odor. The female mite will burrow in the skin, lay eggs, and produce toxins that cause allergic reactions. Larvae (newly hatched mites) travel to the skin surface and lay in shallow pockets where they will develop into adult mites. If the mite is scratched off of the skin it can actually live in the nail bedding for up to 24 hours or more. It may take up to a month before a person will notice the itching, especially in people with good hygiene and who bathe regularly.
Signs & Symptoms:
The earliest and most common symptom of scabies is itching, especially at night. Lille red bumps like hives, tiny bites, or pimples appear. In more advanced cases the skin can become crusty or scaly. Scabies prefers warmer sites on the skin such as skin folds, where clothing is tight, between the fingers, under the nails, on the elbows/wrists, the buttocks or belt line, around the nipples, and even on the penis. Mites also tend to hide in, or on, bracelets and watchbands, or the skin under rings. In children, the infestation may involve the entire body including the palms, soles, and scalp. The child can be irritable from lack of sleep throughout the night and the relentless itch. As is the case with all other dermatology conditions that deal with itching and scratching, bacterial infection can occur due to the scratching of the skin. In many cases, children are treated because of infected skin lesions rather than for the scabies itself. Although this treatment of bacterial infections can provide temporary relief, recurrence is almost certain if the scabies infestation is not treated.
Advanced Cases - Crusted Scabies (Norwegian):
Crusted scabies is a form of the disease in which the symptoms are far more severe. Large areas of the body, like the hands and feet, may be scaly and crusted. These crusts hide thousands of live mites and their eggs, making treatment of the condition difficult because medications applied directly to the skin may not be able to penetrate the thickened skin. This type of scabies occurs most often in the elderly patients, in some AIDS patients, or in people whose immunity is decreased and is extremely infectious.
The Elderly & Nursing Homes:
Scabies among resident patients of nursing homes and extended care facilities has become a common problem due to delayed diagnosis since it can be mistaken for a number of other skin conditions. The delay allows time for the scabies to spread to nursing home staff and other residents. Because residents require assistance in daily activities, this unknowing exposure to infested patients provides an opportunity for the scabies to spread. This happens more often than you might think. Just a few years ago, Dr. David Roy was called in to a nursing home in the Pinebelt to help treat an entire nursing home that had become infested!
How is a Diagnosis Made?
If you came to our facility and presented with scabies-like symptoms, Pine Belt Dermatology & Skin Cancer Center providers would do a head-to-toe examination in good lighting with careful attention to skin crevices. Many times we can make a diagnosis without requiring any special tests. To confirm scabies we do have the ability to apply a drop of oil to the suspected area, scrap the oil-laden skin (painless), and put the scrapings on a glass slide to look under a microscope. We can easily find the mites and/or the mite eggs under the microscope to give you the diagnosis.
Eradication of the Scabies:
There are a number of options to get rid of these pesky mites and their insatiable itch! Getting rid of the mites is critical in the treatment of scabies. Everyone in the family or group, whether itching or not, should be treated at the same time to stop the spread, or recurrence, of scabies. This includes close friends, daycare or school mates, Of course, treatment varies on a case by case basis, but you can most likely expect one of the following options:
If you have an infuriating itch and have not been able to get any answers about the condition, come and see Pine Belt Dermatology and let us give you a diagnosis. Even if the itch you are experiencing is not scabies, we can at least provide you with an answer and a treatment plan for whatever it is you have!
