Pinching the nail of the middle finger and curling the other fingers Is there something wrong with t

CT of the head should be obtained

Hoffmann's disease.

The examiner clamps the distal part of the patient's middle finger with the index finger and middle finger of the right hand to dorsiflex the wrist joint, and the other fingers are in a state of natural relaxed flexion. The examiner uses the thumb to quickly scratch the nail of the middle finger, at this time, the metacarpal flexion reflex of each finger is positive due to the sudden stretching of the flexor muscles of the middle finger, if one side is positive, it indicates that the lateral tendon reflex is hyperreflexial, suggesting pyramidal tract damage, if both sides are positive, and there are no neurological signs, it is not localized.

The entry nerve is the ulnar nerve and median nerve, the center is in the cervical spinal cord 6-8, thoracic 1, and the efferent nerve is the median nerve. Spinal cord lesions, cerebral arteriosclerosis, peripheral nerve damage, neurosis, and increased nerve excitability may also present with this reflex, usually symmetrical, without other signs of pyramidal tracts.

This is a pathological reflex, that is, a reflex that only appears in cases of pathology in the nervous system, that is, in cases of problems, and that healthy adults do not have. A normal reflex, such as the knee reflex, is the reflex that hits the knee and the calf bounces.

The occurrence of pathological reflexes does not necessarily determine the severity of the disease and the specific problem in **, but can only indicate a problem with the nervous system, and the specific problem depends on other examinations.

For your understanding, let me give you an analogy: for example, if a patient is found to have low hemoglobin (similar to pathological reflexes), it means that the patient has a pathological condition and needs to be further examined for the cause of anemia. The result may be that the patient has just donated blood, so it is not a big problem; It is also possible that there is a problem with the kidneys, and a large number of red blood cells are excreted in the urine, which is more troublesome; There may also be blood system diseases, such as hemolysis, which is more dangerous.

The specific situation depends on the results of the next step of the examination.

Nails are keratin that protects the surface of the fingertips, and are made up of a layer of keratin.

Yes, calcium deficiency. You can drink some milk, or calcium tablets, and go to the sun more in winter, so that calcium can be better absorbed!

The nail has obvious transverse fractures, but it is not broken, I don't know what the symptoms are.

It is caused by calcium deficiency, drink more milk and eat some vitamins.

Brown lines on the nails are mostly caused by vitamin A deficiency, pityriasis rubra pilaris, endocrine diseases, etc. Not required if there are no discomfort symptoms**. Spleen and stomach, liver and kidneys are almost. Ensure protein nutrition. In addition, exercise can help with absorption and sleep well.

What I said above, you do it, and you are guaranteed to disappear.

Hello! Have you ever injured your nails? If not, the possibility of onychomycosis should be considered, and further observation is recommended**.

It's not a disease, but your nutrition is uneven. You can observe the thumb, index finger, and middle finger, which is more obvious, and the horizontal groove is almost in the same position. When nutrition is good, the nails grow full.

It is convex, convex and concave, and it becomes a horizontal groove that you are worried about. However, the presence of vertical streaks is a relative lack of water in the body.

The appearance of a horizontal groove nail is generally due to poor nutrition, and it may also be caused by staying up late and eating irregularly.

Nails with many and thin horizontal lines are more common in long-term chronic digestive system diseases. If you don't pay attention to your diet, you will experience symptoms such as abdominal pain and diarrhea. It's okay, it's just that the quality of life is not very good recently, and I'm the same, go to calcium and zinc, vitamins B and C
