A few days ago, Xiaohong found a video of a ten -bu(shi) meal at a certain station, and a young boy had thick calluses on his feet.
The young man's heels and forefoots were wrapped in thick layers of cuticles, and his thumbs began to infect. I can't imagine how these feet could walk.
People usually think that calluses are something that only people who do rough work will have it, and it is unlikely to happen to themselves. However, if you look closely at the fingers of the school bullies, you will find that some people have induration knots on their fingers.
The difference is that the calluses of the school bullies may be caused by long-term pen holding and writing, and you play mobile phone games to type them.
The finger knuckles have calluses, although they can't be seen, but they will always rub against other fingers and feel very uncomfortable, so how should they be treated and improved?
Causes and pathogenesis of corpus callosum
Calluses, also known as calluses, are mainly due to the skin of the hands and feet, long-term compression or friction caused by localized, flattened, hypertrophic damage.
In particular, some bone protruding parts are more susceptible to compression and friction, and callosum is easy to form. The disease is also related to the patient's occupation or foot deformities.
Clinical manifestations of purpuratide
Corpus callosum lesions are generally yellow, flattened, or moundy, bulging, and localizedly thickened translucent cuticle plates. Generally speaking, the central part is thicker, the edge is thinner, the texture is harder, and it is smoother to the touch.
Callosum is commonly seen in the hands and feet, but can also be seen in people with foot deformities, children with nail-biting habits, or manual workers. The course of the disease is slow, there are no self-conscious symptoms, and in severe cases, it may feel oppressive and painful.
What's the difference with corns?
Many people often confuse calluses with corns, both of which are common skin conditions and can occur in the feet and can cause severe discomfort and pain.
But the difference is that the corpus callosum is a diffuse thickening of the outermost layer of the skin (stratum corneum), the result of repeated friction or compression.
Although the corn is also formed by repeated friction or compression, there is a hard "core" in the center of the corn. And the appearance of corns is often accompanied by pain.
Corns often occur in protruding toe bones, or on the back of the toe slit or toe joint.
The main reason for the occurrence of corns is that they often wear shoes that do not fit their feet, or they have abnormal walking postures, rubbing and compressing into joints.
What is the difference from palmar toekeratosis?
The calluses on the feet of the young man mentioned at the beginning are in the case of claurotososis, which is based on excessive production of normal or abnormal keratin in the metatarsal skin.
The most common palmoplantar keratosis (PPK) in white people is called diffuse epidermolytic PPK, which is clinically manifested as thickening and scaling of the metatarsal skin. The epidermis is thickened and involves the entire surface of the palms and soles of the feet.
Most cases are mild or moderate, not systemic, and autosomal dominant.
Are calluses on the joints also calloused callsas?
There may also be some people, calluses growing on the joints on the back of the fingers, which are smooth to the touch. This is not actually a callous callous callus, but a knuckle pad.
Knuckle pads are generally flattened or raised localized keratosis lesions caused by fibrous thickening of the skin of the knuckles.
The surface is smooth or rough, the development is relatively slow, and there are obvious indurations. It is usually found near the interphalangeal joint, and the thumb is rare.
The cause of this disease is generally a family history and is related to heredity. The disease is asymptomatic, cannot be completely removed after surgery, and there is a risk of recurrence.
How should callosum be treated?
If there is really a callousel on the hand or foot, how should it be treated and improved?
First of all, we should try to minimize excessive compression and friction of hands and feet, when the physical stimulation is removed, the time is long, the callosum will disappear on its own, and it is usually necessary to pay attention to wearing shoes or reducing the friction of the fingers (yes, it is said that you hold the mobile phone every day), otherwise the callosum will be more likely to recur after healing.
drug therapy
The treatment of choice is salicylic acid plaster, using a 40% concentration of salicylic acid. Trim the callosum with a knife first, then cut the plaster according to the size of the lesion site, and finally apply the plaster to the lesion site for 2-3 days, paying attention to keeping it dry. Once the lesion has subsided, the paste should be discontinued.
If the lesions have not subsided after 1-2 weeks, they need to go to the hospital for follow-up. In patients with peripheral neuropathy, plaster should not be used.
The above operations, it is best not to operate by yourself, you can first go to the hospital to find relevant professionals to deal with, so that you can prescribe the right medicine as soon as possible and heal as soon as possible.
Well, this is today's content, if you have friends who often hold up their mobile phones, you can share this article to see.
