Types of congenital defects and deformities of the nose - treatment of nasal abnormalities in newborns and child care. Strabismus in infants: normal or pathological

33 reported hereditary diseases with growth retardation. Attention is drawn to their phenotypic similarity and the real difficulties of distinguishing them from each other. It is proposed to select two groups and a table differential diagnosis .

Substantial part hereditary pathology childhood clinically expressed by a sharp retardation of children's growth. The variety of nosological forms and the relatively low frequency of many of them create great difficulties in the process of differential diagnosis of these conditions.

From the standpoint of differential diagnosis, it is advisable to divide a large group of diseases into separate subgroups - growth retardation against the background of a sharp disproportion of the skeleton and growth retardation with a proportional shape of the skeleton.

A. Differential diagnosis diseases accompanied by stunting and severe skeletal disproportion

This group is extremely heterogeneous. It includes diseases classified according to the classification of M.V. Volkov, E.M. Meersov et al. to epiphyseal dysplasia - pseudochondroplasia, etc.; physeal - achondroplasia, etc.; spondyloepimetaphyseal - parastrematic dysplasia, etc.; diaphyseal dysplasia - imperfect bone formation, etc.; representatives of mixed forms systemic diseases skeleton - Ellis-van-Creveld disease; mucopolysaccharidoses.

Most nosological forms are characterized by the manifestation of clinical signs from birth or from the first months of life. In a number of diseases (Seckel syndrome, Russell-Silver syndrome, etc.), children are born with a short body length. Below is a brief clinical characteristics diseases.

Classmates

Not all parents know that strabismus in infants is often physiological norm. In order to understand when you should immediately go to the doctor with such a problem, and when you should not worry, you need to understand why this happens.

What is the norm?

In an adult, the axes of the eyes normally coincide completely. Deviation from this is called strabismus, or strabismus. There is another clinical name - heterotropia. There are two main types of strabismus:

  1. Converging. In this case, one or two eyes slant towards the bridge of the nose. In infants this is exactly the type observed (in 90% of cases).
  2. Divergent. One or both eyes move towards the temple.

As a result of the fact that the newborn baby often experiences weakness oculomotor muscles, for this reason heterotropia develops.

Movement control is not always available to him at birth eyeballs. It is important for parents to know when this phenomenon occurs, since such a process cannot be started.

Only 9% of seven-year-old children of the total number of children with strabismus persist. Over time, the eye muscles become stronger, and there is no longer any reminder that the baby had strabismus.

The structural features of the skull bones and the wide bridge of the nose also lead to the fact that the child has some deviation. It goes away in a few months.

Causes of pathological strabismus

But there are a number of cases in which normalization does not occur. The causes of this pathology may be:

  • birth complications;
  • lack of oxygen during intrauterine development;
  • infection and intoxication of the fetus;
  • previous measles, scarlet fever or influenza;
  • neurological abnormalities;
  • hereditary predisposition;
  • improper placement of toys above the bed.

Psycho-emotional stress (screaming, bright light, etc.) can lead to the temporary appearance of strabismus in a newborn.

If strobism is observed for more than six months, it leads to impaired visual acuity and the development of amblyopia.

When to go to the doctor?

Despite the fact that strabismus can go away a month after birth, or three, but normally this phenomenon should not be observed in a six-month-old baby.

It is at this age that strabismus refers to pathological condition, and is a reason to see a doctor.

Distinguish the following types diseases:

  • by time of appearance - congenital or acquired;
  • permanent and temporary;
  • one-sided or alternating;
  • convergent, divergent and vertical.

Separately, we should highlight the paralytic type, in which the eye does not move in a certain direction as a result of damage to a muscle or nerve.

How to prevent the disease?

To prevent strobism from causing vision loss, there is prevention of strabismus in infants.

If a baby has strabismus at the age of one month, then you need to do the following:

    1. Hang bright toys above the center of the crib at such a distance that the baby would not be able to reach them with his hand.
    2. Toys should only be large sizes.
    3. Do gymnastics to strengthen the eye muscles. For this purpose, you need to take a large and bright rattle and move it from side to side so that the baby follows it with his eyes.
    4. Pass at two months of age routine inspection specialist and follow all his recommendations.

Treatment

On this moment There are 25 types of strabismus. For this reason, only a specialist should treat it. In each case, only an individual approach is applied.

Such a disease should not be neglected, as vision may gradually decrease sharply.

Once diagnosed, treatment is as follows:

  1. Until all symptoms are completely eliminated, the child is given corrective glasses or soft lenses.
  2. To improve the functioning of the affected eye, the occlusion method is used. It consists of closing the healthy eye for a while and forcing the sick one to work.
  3. A variety of techniques are used to restore binocular vision.
  4. If the child turns four years old, then complex treatment orthopedic and acupuncture therapy is used.

If a paralytic form of strobism is detected, consultation with a pediatric neurologist is necessary!

If there is no effectiveness, the doctor may recommend surgery. It is carried out under general anesthesia. After this, the child undergoes rehabilitation and strengthens eye muscles with the help of special exercises.

The presence of strabismus in a newly born baby is not a reason to panic; for the first few months of his life he cannot focus his gaze.

But in most cases, by 4-6 months this phenomenon disappears without leaving a trace. Correct prevention will help to avoid the transition of physiological strabismus to pathology.

Passing through the birth canal, the baby’s entire body is greatly compressed, as a result of which the newborn’s head may have asymmetry and the face may be swollen.

Head of a newborn baby

The head of a newborn is relatively large; immediately after birth, almost every child can notice some deformation of the head, less often - asymmetry is obvious. As a rule, any such changes are temporary and they should not frighten young parents.

The main cause of deformation, as already mentioned, is the process of the little man passing through the birth canal. The fact is that the bones of the child’s skull are forced to shift slightly relative to each other during this difficult journey. For this reason, experts have identified a certain pattern: the larger the baby’s head, the more deformation it will be subject to. As a rule, a large head is characteristic of a large fruit.

Babies who were born with the help do not have a noticeable deformation of the head.

If you carefully and carefully feel the head of a newborn baby, you can easily detect the so-called fontanelles. They are a soft area of ​​skin between the bones of the skull; when you press lightly with your finger on such areas, you can feel some pulsation. The largest fontanel is located just above the top of the head, the second is slightly lower from the large one. As the baby grows, his fontanelles tighten; As a rule, by the age of one year they completely disappear.

Newborn baby's face

In the first hours after birth, the newborn’s face still retains traces of strong compression: the nose is flattened, the eyelids are slightly swollen, the skin is swollen, with a reddish tint. In the folds on the face (in the nose area), behind the ears there are small accumulations of a special secretion in the form of white/yellowish dots, thanks to this lubricating secretion it was easier for the child to pass through the birth canal. You shouldn’t remove such accumulations yourself; they will go away on their own over time.

We should also talk about the nose of a newborn. Immediately after birth, this olfactory organ will be slightly flattened and may appear to be very large. This condition, again, is explained by the journey that the baby had to go through. In a couple of days, the baby’s nose will become neat.

In the very first minutes after birth, all nasal cavity the newborn is filled with amniotic fluid, which doctors remove themselves using a special suction. The baby's nasal cartilage is very soft. The nasal passages are relatively narrow, have a large number of blood vessels, therefore, if the vessels dilate (i.e., the mucous membrane swells), then the baby’s breathing becomes significantly more difficult. If breathing is difficult, the baby will often pause during feeding to inhale air through the mouth. inevitable.

Experts say that a newborn is able to distinguish smells almost immediately after birth. Even they can boast of a good sense of smell. In this regard, a young mother should remember: experiments with eau de toilettes/deodorants are best left for later if she wants to breastfeed her baby for a long time.

If the baby is large, then, most likely, some deformation of the face will be visually noticeable: during the birth process, not only the bones of the skull, but also the bones on the child’s face shifted. A young mother will not find such a face attractive, but by the time she is discharged, the baby’s skin will have time to smooth out and he will appear before his dad (and other relatives) in his very beauty.
