Thymus gland: hidden possibilities of the body for rejuvenation. Thymus or thymus gland: where is it located and what is it responsible for, causes of pathological processes and types of damage to an important organ of the endocrine system Thymus ectopia in the thyroid gland

Content

People don't know everything about their bodies. Where the heart, stomach, brain and liver are located is known to many, and the location of the pituitary gland, hypothalamus or thymus is not known to many. However, the thymus or thymus gland is a central organ and is located in the very center of the sternum.

Thymus gland - what is it

Iron got its name due to the shape resembling a two-pronged fork. However, a healthy thymus looks like this, and a sick one takes on the appearance of a sail or a butterfly. For its proximity to the thyroid gland, doctors used to call it the thymus gland. What is thymus? This is the main organ of vertebrate immunity, in which the production, development and training of T-cells of the immune system takes place. The gland begins to grow in a newborn baby before the age of 10, and after the 18th birthday it gradually decreases. The thymus is one of the main organs for the formation and activity of the immune system.

Where is the thymus located

The thymus can be identified by placing two folded fingers on the top of the sternum below the clavicular notch. The location of the thymus is the same in children and adults, but the anatomy of the organ has age-related features. At the time of birth, the mass of the thymus organ of the immune system is 12 grams, and by puberty it reaches 35-40 g. Atrophy begins at about 15-16 years. By the age of 25, the thymus weighs about 25 grams, and by 60 it weighs less than 15 grams.

By the age of 80, the weight of the thymus gland is only 6 grams. The thymus by this time becomes elongated, the lower and lateral parts of the organ atrophy, which are replaced by adipose tissue. This phenomenon is not explained by official science. Today it is the biggest mystery of biology. It is believed that opening this veil will allow people to challenge the aging process.

The structure of the thymus

We have already found out where the thymus is located. The structure of the thymus gland will be considered separately. This small-sized organ has a pinkish-gray color, soft texture, and a lobed structure. The two lobes of the thymus are completely fused or closely adjacent to each other. The upper part of the body is wide, and the lower one is narrower. The entire thymus gland is covered with a capsule of connective tissue, under which there are dividing T-lymphoblasts. The jumpers that depart from it divide the thymus into lobules.

The blood supply to the lobular surface of the gland comes from the internal mammary artery, thymic branches of the aorta, branches of the thyroid arteries and the brachiocephalic trunk. Venous outflow of blood is carried out through the internal thoracic arteries and branches of the brachiocephalic veins. In the tissues of the thymus, the growth of various blood cells occurs. The lobular structure of the organ contains cortex and medulla. The first looks like a dark substance and is located on the periphery. Also, the cortical substance of the thymus gland contains:

  • hematopoietic cells of the lymphoid series, where T-lymphocytes mature;
  • hematopoietic macrophage series, which contain dendritic cells, interdigitating cells, typical macrophages;
  • epithelial cells;
  • supporting cells that form the hemato-thymic barrier, which form the tissue framework;
  • stellate cells - secreting hormones that regulate the development of T-cells;
  • baby-sitter cells in which lymphocytes develop.

In addition, the thymus secretes the following substances into the bloodstream:

  • thymic humoral factor;
  • insulin-like growth factor-1 (IGF-1);
  • thymopoietin;
  • thymosin;
  • thymalin.

What is responsible for

Thymus in a child forms all the systems of the body, and in an adult it maintains good immunity. What is the thymus responsible for in the human body? The thymus gland performs three important functions: lymphopoietic, endocrine, immunoregulatory. It produces T-lymphocytes, which are the main regulators of the immune system, that is, the thymus kills aggressive cells. In addition to this function, it filters the blood, monitors the outflow of lymph. If any malfunction occurs in the work of the organ, then this leads to the formation of oncological and autoimmune pathologies.

In children

In a child, the formation of the thymus begins at the sixth week of pregnancy. The thymus gland in children under one year old is responsible for the production of T-lymphocytes by the bone marrow, which protect the child's body from bacteria, infections, and viruses. An enlarged goiter (hyperfunction) in a child does not affect health in the best way, as it leads to a decrease in immunity. Children with this diagnosis are susceptible to various allergic manifestations, viral and infectious diseases.

In adults

The thymus gland begins to involute with age, so it is important to maintain its functions in a timely manner. Thymus rejuvenation is possible with a low-calorie diet, taking Ghrelin, and using other methods. The thymus gland in adults is involved in modeling two types of immunity: a cell-type response and a humoral response. The first forms the rejection of foreign elements, and the second manifests itself in the production of antibodies.

Hormones and functions

The main polypeptides produced by the thymus gland are thymalin, thymopoietin, thymosin. By their nature, they are proteins. When lymphoid tissue develops, lymphocytes get the opportunity to take part in immunological processes. Thymus hormones and their functions have a regulatory effect on all physiological processes in the human body:

  • reduce cardiac output and heart rate;
  • slow down the work of the central nervous system;
  • replenish energy reserves;
  • accelerate the breakdown of glucose;
  • increase the growth of cells and skeletal tissue due to increased protein synthesis;
  • improve the work of the pituitary gland, thyroid gland;
  • produce the exchange of vitamins, fats, carbohydrates, proteins, minerals.

Hormones

Under the influence of thymosin, lymphocytes are formed in the thymus, then, with the help of the influence of thymopoietin, blood cells partially change their structure to ensure maximum protection of the body. Timulin activates T-helpers and T-killers, increases the intensity of phagocytosis, accelerates regeneration processes. Thymus hormones are involved in the work of the adrenal glands and genital organs. Estrogens activate the production of polypeptides, while progesterone and androgens inhibit the process. A glucocorticoid, which is produced by the adrenal cortex, has a similar effect.

Functions

In the tissues of the goiter, blood cells proliferate, which enhances the immune response of the body. The resulting T-lymphocytes enter the lymph, then colonize in the spleen and lymph nodes. Under stressful influences (hypothermia, starvation, severe trauma, and others), the functions of the thymus gland weaken due to the massive death of T-lymphocytes. After that, they undergo positive selection, then negative selection of lymphocytes, then regenerate. The functions of the thymus begin to fade by the age of 18, and fade almost completely by the age of 30.

Thymus gland diseases

As practice shows, diseases of the thymus are rare, but always accompanied by characteristic symptoms. The main manifestations include severe weakness, an increase in lymph nodes, a decrease in the protective functions of the body. Under the influence of developing diseases of the thymus, lymphoid tissue grows, tumors are formed that cause swelling of the limbs, compression of the trachea, borderline sympathetic trunk or vagus nerve. Malfunctions in the work of the body are manifested with a decrease in function (hypofunction) or with an increase in the work of the thymus (hyperfunction).

magnification

If the ultrasound photo showed that the central organ of lymphopoiesis is enlarged, then the patient has thymus hyperfunction. Pathology leads to the formation of autoimmune diseases (lupus erythematosus, rheumatoid arthritis, scleroderma, myasthenia gravis). Hyperplasia of the thymus in infants is manifested in the following symptoms:

  • decrease in muscle tone;
  • frequent regurgitation;
  • weight problems;
  • heart rhythm failures;
  • pale skin;
  • profuse sweating;
  • enlarged adenoids, lymph nodes, tonsils.

hypoplasia

The central organ of human lymphopoiesis may have congenital or primary aplasia (hypofunction), which is characterized by the absence or weak development of the thymic parenchyma. Combined immunological deficiency is diagnosed as a congenital disease of Dee George, in which children have heart defects, convulsions, anomalies of the facial skeleton. Hypofunction or hypoplasia of the thymus gland can develop against the background of diabetes mellitus, viral diseases, or alcohol consumption by a woman during pregnancy.

Tumor

Thymomas (tumors of the thymus) occur at any age, but more often such pathologies affect people from 40 to 60 years old. The causes of the disease have not been established, but it is believed that a malignant tumor of the thymus arises from epithelial cells. It is noticed that this phenomenon occurs if a person suffered from chronic inflammation or viral infections or was exposed to ionizing radiation. Depending on which cells are involved in the pathological process, the following types of tumors of the goiter gland are distinguished:

  • spindle cell;
  • granulomatous;
  • epidermoid;
  • lymphoepithelial.

Symptoms of thymus disease

When the work of the thymus changes, an adult feels a violation of breathing, heaviness in the eyelids, muscle fatigue. The first signs of thymus disease are a long recovery after the simplest infectious diseases. In violation of cellular immunity, symptoms of a developing disease begin to appear, for example, multiple sclerosis, Basedow's disease. With any decrease in immunity and the corresponding signs, you should immediately contact the doctor.

Thymus gland - how to check

If a child has frequent colds that turn into severe pathologies, there is a greater predisposition to allergic processes, or lymph nodes are enlarged, then a diagnosis of the thymus gland is needed. For this purpose, a sensitive high-resolution ultrasound machine is needed, since the thymus is located near the pulmonary trunk and atrium, and is closed by the sternum.

In case of suspicion of hyperplasia or aplasia, after a histological examination, the doctor may refer you to computed tomography and examination by an endocrinologist. The tomograph will help to establish the following pathologies of the thymus gland:

  • MEDAC syndrome;
  • DiGeorge syndrome;
  • myasthenia gravis;
  • thymoma;
  • T-cell lymphoma;
  • pre-T-lymphoblastic tumor;
  • neuroendocrine tumor.

Norms

In a newborn baby, the size of the thymus gland is on average 3 cm wide, 4 cm long and 2 cm thick. The average size of the thymus is normally presented in the table:

Width (cm)

Length (cm)

Thickness (cm)

1-3 months

10 months - 1 year

Pathology of the thymus

In violation of immunogenesis, changes in the gland are observed, which are represented by such diseases as dysplasia, aplasia, accidental involution, atrophy, hyperplasia with lymphoid follicles, thymomegaly. Often, thymus pathology is associated either with an endocrine disorder, or with the presence of an autoimmune or oncological disease. The most common cause of a decline in cellular immunity is age-related involution, in which there is a deficiency of melatonin in the pineal gland.

How to treat the thymus

As a rule, thymus pathologies are observed up to 6 years. Then they disappear or turn into more serious diseases. If the child has an enlarged goiter gland, then a phthisiatrician, immunologist, pediatrician, endocrinologist and otolaryngologist should be observed. Parents should monitor the prevention of respiratory diseases. If symptoms such as bradycardia, weakness and/or apathy are present, urgent medical attention is required. Treatment of the thymus gland in children and adults is carried out by medical or surgical methods.

Medical treatment

When the immune system is weakened, to maintain the body, it requires the introduction of biologically active substances. These are the so-called immunomodulators that thymus therapy offers. Treatment of the goiter gland in most cases is carried out on an outpatient basis and consists of 15-20 injections that are injected into the gluteal muscle. The treatment regimen for thymus pathologies may vary, depending on the clinical picture. In the presence of chronic diseases, therapy can be carried out for 2-3 months, 2 injections per week.

Intramuscularly or subcutaneously, 5 ml of thymus extract isolated from the peptides of the goiter gland of animals is injected. It is a natural biological raw material without preservatives and additives. Already after 2 weeks, improvements in the general condition of the patient are noticeable, since protective blood cells are activated during the treatment. Thymus therapy has a long-term effect on the body after the therapy. A second course can be carried out after 4-6 months.

Operation

Thymectomy or removal of the thymus is indicated if the gland has a tumor (thymoma). The operation is performed under general anesthesia, which keeps the patient asleep during the entire operation. There are three types of thymectomy:

  1. Transsternal. An incision is made in the skin, after which the sternum is separated. The thymus is separated from the tissues and removed. The incision is closed with staples or sutures.
  2. Transcervical. An incision is made along the lower part of the neck, after which the gland is removed.
  3. Video assisted surgery. Several small incisions are made in the upper mediastinum. A camera is inserted through one of them, displaying the image on the monitor in the operating room. During the operation, robotic arms are used, which are inserted into the incisions.

diet therapy

Diet therapy plays an important role in the treatment of thymus pathologies. Foods rich in vitamin D should be introduced into the diet: egg yolk, brewer's yeast, dairy products, fish oil. The use of walnut, beef, liver is recommended. When developing a diet, doctors advise including in the diet:

  • parsley;
  • broccoli, cauliflower;
  • oranges, lemons;
  • sea ​​buckthorn;
  • syrup or decoction of wild rose.

Alternative treatment

Children's doctor Komarovsky advises to warm up the thymus with a special massage to increase immunity. If an adult has an unreduced gland, then he should maintain immunity for prevention by taking herbal preparations with rose hips, black currants, raspberries, and lingonberries. Treatment of the thymus with folk remedies is not recommended, since the pathology requires strict medical supervision.

Eugene asks:

Hello. The boy is 7 years old. Today they did an ultrasound, they said that the shield of the gland was increased to 12 cm, at a rate of 4. I have no more data. Passed a blood test for TSH, T4 St and ATkTPO. Waiting for a response. (The husband left the ultrasound with the doctor). Dz was previously written like this: endemic goiter 1st. and Chr AIT? Acceptance after analysis. How serious is it that the shield of iron is so greatly increased? The child is normal and develops normally. I don't see any deviations. Tell me, is this serious?

Answers:

Hello Evgeniya! In fact, at the moment we have nothing to base our assumptions on. Even the result of ultrasound you write from the words of your husband, and the figure of 12 cm raises serious doubts. Therefore, at this stage, we can not say anything specific. AIT (autoimmune thyroiditis) and endemic goiter are treatable diseases. Therefore, you just need to wait until the end of the examination and start treating the child. Take care of your health!

Julia asks:

Ultrasound examination of the thyroid gland: usually located, left lobe length 33.2 width 9.6 thickness 10.7 volume 1.6 right lobe length 37 width 10.7 thickness 11.4 volume 2.2 isthmus 2.7 echogenicity is normal, lymph nodes are not enlarged. A fiery cyst with a diameter of 5.9-3.1 was found c / z of the left lobe of the bronchi; in conclusion, a non-thyroidal formation on the left. Blood test TSH-1.15. What does this mean, what are our further actions with the child? A year ago, during an ultrasound of the thyroid done by a thyroidologist, a thyroid ectopia of the thymus was detected outside the thyroid formation, the doctor then told me that this was a feature of nothing terrible, he did not see, and today it was not a thyroidologist who did the ultrasound, the endocrinologist advised us to consult with local surgeons and take iodomarin daily, see the endocrinologist in six months . Tell me what to do with the cyst, what are our next steps?

Responsible Berezhnaya Irina Yurievna:

Hello Julia First of all, it is necessary to clarify the diagnosis: thymus (hardly ectopia, most likely visualization) or ectopic tissue of the thyroid gland. More trustworthy is the conclusion of a doctor a year ago, since there is no bronchiogenic cyst in the thyroid gland. You just need to do a CT scan (MRI) of the neck area and consult with a pediatric endocrinologist. I hope that the surgeon's help here will only be needed advisory. Just investigate.

asks Elena, 31 years old, Saratov:

Hello, please tell me! My daughter is 6 years old, height 129 cm, weight 32 kg. They tested for hormones, as a result of TSH-6.85 mIU / l, T4-20.8 nmol / l.
tell me, I beg you, the increased TSH may be due to the fact that the height and weight of my daughter is much greater than that of her peers?
Does the discrepancy between the height and weight of the child for age affect the level of the hormone TSH?

Answers:

Hello, Elena. The TSH hormone regulates the functioning of the thyroid gland, in this case it is elevated (there is a reduced work of the thyroid gland), which can be manifested by a decrease in the rate of metabolic processes (including weight gain). It is necessary to do an ultrasound of the thyroid gland and antibodies (analysis of ATPO, AMS, ATTH), growth hormone STH and, if necessary, an x-ray of the hands to determine whether the bone age corresponds to the passport one. Sincerely, Natalya Vasilievna.

Gulmira asks:

Hello. I am 32 years old. In 2011, I was diagnosed with primary hypothyroidism. I am currently taking Euthyrox 50mg. In my daughter's analysis: TSH - 14.7 μIU / ml, T4 free - 12.1 Pmol / l what does this mean? what drugs should we take? My daughter is growing according to her age.

Responsible Medical consultant of the health-ua.org portal:

Hello, the results of your child's tests indicate the presence of subclinical hypothyroidism (high TSH). It is necessary to contact a pediatric endocrinologist for further additional examination and therapy. Children with subclinical hypothyroidism are also shown to be prescribed thyroid hormone replacement therapy and iodine preparations, after establishing the cause. The appointment of therapy is carried out only by a pediatric endocrinologist with careful selection and adjustment of doses.

Vladimir asks:

Good afternoon, tell me - is it worth giving a 3.5-year-old child iodamarin for prevention ?? and if so, how much?

Responsible Medical consultant of the health-ua.org portal:

Hello Vladimir! If you live in an area with insufficient iodine in the environment, iodine prophylaxis will not hurt. Children under 12 years of age can be given iodomarin at a dose of 50-100 mg per day, after agreeing the dose of the drug with the attending physician (pediatrician). Perhaps your child is already receiving a multivitamin-mineral complex, which includes iodine, in which case the dose of iodine should be adjusted taking into account the iodine content of this preparation. Take care of your health!

Christina asks:

Good afternoon! Daughter 6 years 7 months. Height 121, weight 22. Bone age 7 years. They did an ultrasound of the thyroid gland. Dimensions: right lobe 0.68 cm, thickness 0.76 cm, length 2.26 cm, volume 1.2 cm in 3. Left lobe width 1.03 cm, thickness 0.66 cm, length 2 .05 cm, volume 1.7 cm in 3. Isthmus thickness 0.13 mm, total volume 1.4 ml. We were referred to an endocrinologist. Is there any deviation from the norm. Thank you!!!

Responsible Berezhnaya Irina Yurievna:

Hello Christina The total volume of an organ in a child aged 6-14 should be 4.9-5.0 cm3 (Brunno). When measuring a volume that differs from statistical data, an endocrinologist's consultation is certainly needed. The purpose of the consultation: whether these data are physiological characteristics or additional examination is necessary (presence of iodine in the urine, TSH level in the blood ...). It is not excluded repeated ultrasound examination of the thyroid gland in a specialized center.

Tatyana asks:

Hello! Please help me figure it out. Ultrasound showed that vascularization is enhanced during color doppling. right lobe-v=1.8cm3, left lobe v=1.6cm3. handed over for hormones TSH = 1.6 mMe / l,
T4= 22.0pmol/l, T3=7.2pmol/l, ATPO=0.
The child has reduced weight, constant hand tremor, heart palpitations. In the clinic, the endocrinologist said that the child is fine, and the hand tremor is age-related. Help with advice.

Responsible Berezhnaya Irina Yurievna:

Hello, Tatyana Examination of the thyroid gland revealed no abnormalities: ultrasound and hormonal examinations are unchanged. The endocrinologist's task is to exclude thyrotoxicosis and pheochromocytoma (tremor can be detected in these diseases). Unfortunately, you did not indicate the age of the child. In any case, you need the help of a pediatric neurologist. tremor can be both a consequence of the immaturity of the nervous system (physiologically) and early signs of disease.

Hope asks:

Hello.
The child was born at 41-42 weeks 3 kg 360. Tight entanglement of the umbilical cord. Prolonged jaundice 325. Treatment for 3 weeks, discharge at 140.
Analyzes and ultrasound May 2014. Daughter 8.5 years old 29kg 138cm
TSH 6.36 T4sv 10.17 a/t to TPO 0.3 TG 0.2.
Ultrasound of the thyroid gland (28.05.14) Increased in size, diffuse cystic changes in the parenchyma. Total volume 5.36
Treatment: Vit B1, V6v / m No. 10, Elkar, Pantogam 0.25 3 r per day, Iodomarin 3 months, glycine.

Repeated tests November 2014. Daughter 142cm 32kg 9 years
ST4 13.0 TSH 6.9
Previously, my daughter was healthy, for 2 years now she has been feeling unwell, complaints: weakness, headaches, sweating, pain in the abdomen and heart, soreness and discomfort in the throat.
They also did an ultrasound of the abdominal cavity (03/25/14)
Conclusion: Signs of cholecystitis cholongitis. Signs of superficial gastritis. Reactive changes in the pancreas. (Addition: Severe flatulence)

Please help me to decipher and understand our results, analyzes, and can it be that the problems of the abdominal cavity that we are concerned about are related to thyroid problems? I am also very worried about perspiration, suffocation, discomfort in the throat.
Thank you very much in advance for your advice.

Responsible Berezhnaya Irina Yurievna:

Hello Nadezhda In my opinion, the child can be diagnosed with subclinical hypothyroidism (SH), which requires the appointment of L-thyroxine. All accompanying complaints can be associated with SH: a decrease in the secreto- and acid-forming function of the stomach and a significant increase in the content of mucoproteins and a decrease in the ratio of phospholipids/cholesterol in serum. The prescribed treatment is inadequate. A specialized consultation with an endocrinologist is required.

Inna asks:

Hello, please decipher the tests! How scary is everything? and what to do? The child is 7 years old, height 115, weight 23 kg. FT4-16.32 and TSH-5.16 Many thanks in advance!

Responsible Medical consultant of the health-ua.org portal:

Hello Inna! It is not possible to interpret the results of the above study, because you did not indicate the sex of the child, did not provide units of measurement and data on the reference (normal) limits used in the laboratory that performed the analysis (printed on the analysis form to the right or left of the study results). Complete your message with the necessary information or discuss the results of the analysis with your doctor. Take care of your health!

Elena asks:

Hello! My girl is 10 years old. According to the measurements of the endocrinologist, she looks 12.5 years old (height - 152 cm, weight - 68 kg). They took a blood test for hormones. T4 free - 9.17 pmol / l, TSH - 4.43 μU / ml and we were diagnosed with exogenous constitutional obesity E66.0: 2 degrees and subclinical hypothyroidism E02.0
The doctor prescribed us Euthyrox 75 mcg.
Prompt please - whether it is necessary to us at such results to sit down on hormones.

Responsible Renchkovskaya Natalya Vasilievna:

Hello, Elena. The girl needs to do an ultrasound, in the tests it is necessary to exclude autoimmune thyroiditis (an for antibodies AMS, ATPO), the dose of euthyrox is prescribed with a minimum (half a tablet from a dose of 25) or a homeopathic option so as to balance the level of TSH. It is also important to assess the appropriate bone and passport age, the degree of sexual development and write down an individual balanced diet. With uv. Natalya Vasilievna.

Zlata asks:

Good afternoon. The child is 1 year and 7 months old, tested for thyroid hormones: T3- 1.72; T4 - 10.22; TSH- 1.63; ATTG-1034.98; ATTPO- 720.08; Ultrasound of the thyroid gland: Isthmus - 1.06
Right lobe (length 21.4; width 8.41; thickness 10.2; U of the right lobe 0.88; not enlarged). Left lobe (length 19.6; width 9.54; thickness 10.6; U of the right lobe 0.95; not enlarged). The total U thyroid 1.8 is not increased. It is typically located, the contours are clear, even. The capsule of the thyroid gland is not thickened, not compacted. the structure is homogeneous, echogenicity is normal. What can cause such blood tests and what consequences can this lead to? Can eat ways to normalize antibodies?

Responsible Volobaeva Ludmila Yurievna:

Good health! It is important to understand the purpose for which antibodies were determined for such a small child, whether relatives have thyroid diseases. An increase in antibodies is only a risk factor for the development of hypothyroidism in the future, but there is no need to reduce them. Medicine, at this stage of development, is not capable of doing this. In such a situation, it is only necessary to control TSH once every 6 months and ultrasound of the thyroid gland once a year. Antibodies do not need to be treated.

Oleg asks:

Hello! Girl 6 years old, height 122.5 cm, weight 30 kg. Ultrasound showed an increase in the thyroid gland by 34% + cholesterol readings were overestimated by 5.28 (mmol / l). On the basis of the analyzes, a course of iodomarin was prescribed by the doctor in the polyclinic. It would be desirable to receive your references, leaning against the given results of analyses. Regards, Oleg.

Responsible Kravchun Nonna Alexandrovna:

Hello Oleg! The reasons for the enlargement of the thyroid gland can be different - inflammation, autoimmune process, lack of iodine. There is not enough information to make a diagnosis - you need to study the function of the thyroid gland - donate blood for T3, T4, TSH, ATPO and AT-TG (thyroid profile). Only in combination with the results of these tests will it be possible to establish the true cause of the enlargement of the gland and prescribe the appropriate treatment. Do not be ill!

Ultrasound examination of the thyroid gland: when and why to do it

The thyroid gland is without a doubt one of the most important organs in the human body. The production of hormones responsible for metabolism and energy depends on its functioning. If something is wrong with the thyroid gland, then the consequences will manifest themselves in the most unexpected areas of the body's life.

To find out the cause of the failure in the gland, you need to contact an endocrinologist. The doctor will prescribe tests and an ultrasound of the thyroid gland.

Why do you need to do an ultrasound of the thyroid gland

A fairly common pathology of the thyroid gland is hypothyroidism, provoked by iodine deficiency. When this element enters the body not regularly, but with malfunctions, the first signs are not long in coming: hair falls out, skin dries, nails break, swelling and problems with sleep appear.

Suspect thyroid problems if some of the following symptoms are found:

  • apathy;
  • lethargy;
  • mood swings;
  • weakness;
  • drowsiness;
  • cardiac arrhythmia (see Thyroid gland and heart - what is the connection?);
  • changes in weight (if there are not enough hormones, then excess weight appears, and with an increased level of hormones, exhaustion comes).

The spectrum of manifestations of other pathologies of the thyroid gland may include many other symptoms.

In case of suspected thyroid disease, an ultrasound will be one of the first tests that a doctor will prescribe. Ultrasound examination is the study of any organ without penetration through the skin or mucous membranes of a person using ultrasonic waves.

Ultrasound examination will help to find out parameters such as:

  1. The structure of the thyroid gland. Normally, the organ consists of two lobes and the isthmus connecting them. Often there is a pyramidal part (lobe), located next to the gland or just above the isthmus. Perhaps the presence of tissue outgrowths, about a centimeter long, they are located near the lower edges of the lobes to the thymus gland. In prenatal development, a failure in the formation of the thyroid gland may occur, and as a result, there is no division into two lobes, this deviation is called aplasia (agenesis) of the lobe in the thyroid gland. If the development of the gland is absent, then the diagnosis is “complete aplasia”.
  2. The position of the thyroid gland is divided into typical, low, pathological (aberrant). Ectopia is also possible - the tissues of the thyroid gland go beyond the boundaries of their organ, which is possible with both the lobes and the isthmus.
  3. Contours, normally, should be clearly visible. If they are fuzzy, then this may indicate inflammation or a tumor.
  4. The structure should be homogeneous, with its inherent graininess. Heterogeneity can be a signal of an inflammatory process.
  5. Dimensions of the thyroid and parathyroid glands.
  6. Echogenicity - tone and shade of thyroid tissue.
  7. The formations are examined in case of the presence of nodes, cysts (see Cyst in the thyroid gland: symptoms and signs of pathology), or calcifications.
  8. Particular attention is paid to the presence, size, structure and structure of the lymph nodes accessible to the apparatus, which can reveal microcalcifications, increased blood flow and other signs of the process of tumor formation.
  9. The structure of the salivary gland located near the ears.
  10. The size and structure of the larynx, as well as the soft tissues of the neck - to study the areas around the thyroid gland.

About undergoing a thyroid ultrasound procedure

So, how do you prepare for an ultrasound examination of such a tiny organ as the thyroid gland? The answer is simple: no way. No special action is needed. However, it is better for both young children and the elderly to have an ultrasound scan on an empty stomach, otherwise the gag reflex can be uncomfortable.

For the procedure, you need to take a towel with you: first, you can make a roller out of it and put it under your neck for greater convenience, and then it’s convenient for them to wipe the gel from your neck. If this procedure is not the first for the subject, then the previous ultrasound results should also be taken with you.

The very procedure of what is happening is as follows: throwing back his head, the subject lies down on the couch. On the neck, the specialist applies a special gel designed for a better ultrasound signal.

Then the study itself is carried out. The signal of a special sensor that works with ultrasonic waves is reflected from the thyroid tissue and then read by the same sensor. The signal is then examined and the result appears on the screen as an image of the thyroid gland.

The process does not cause any painful sensation, however, there may be discomfort due to the uncomfortable position of the head and neck. The whole process takes approximately 30 minutes.

It is often possible to get a free ultrasound in city clinics, but those who do not want or cannot wait in line can go to a paid clinic. The price depends on the city. For preventive purposes, it is enough to do an ultrasound examination once a year.

Significance of the obtained results of ultrasound examination

In the presented photo of the ultrasound of the thyroid gland, you can see it in different projections. The dotted line marks the contours, and the arrows mark the size of the shares. The pictures "a" and "c" show the transverse and longitudinal sections of the thyroid gland, the photo "b" shows the asymmetry of the lobes of the gland, and the picture "d" shows the normal vascular pattern.

Of course, only a specialist should decipher the results of ultrasound, since there are many large vessels in the human neck, lymph nodes, the thyroid, parathyroid and salivary glands, as well as organs such as the trachea and esophagus. However, some parameters can be understood by knowing the norm in advance.

The structure of the thyroid gland should be even, homogeneous. For men, the normal volume of the thyroid gland, according to medical indicators, should not exceed 25, and for women, on average - But you need to understand that these are only average indicators that fluctuate depending on the weight of the subject.

The table below will help guide you:

For children under 16 years old, other sizes are characteristic. It must be borne in mind that the size of the thyroid gland in boys and girls of the same year of birth is different, the difference can reach 1.5.

Approximate norms for the volume of the gland in children aged 6 to 15 years are as follows:

The thickness and size of the lobes in the thyroid gland can also be of different sizes, but among them there are also average indicators:

  • the approximate size of the shares is 4x2x2 cm;
  • the right and left shares should also be equal to each other;
  • the norm of the thickness of the isthmus is considered to be the size of 4-5 mm.

Also in a healthy person, according to the results of ultrasound:

  • the contours of the thyroid gland are even and clearly visible;
  • cervical lymph nodes are normal;
  • the parathyroid glands are about 4x5x5 mm in size.

You can learn more about the results of ultrasound of the thyroid gland from the video in this article.

Thyroid diseases that can be detected by ultrasound

When ultrasound diagnostics of thyroid diseases displays a deviation from the indicators correlated with the norm on the monitor, this may indicate such diseases of the endocrine system:

  1. Thyroiditis. An enlarged thyroid gland and swelling are more likely to indicate thyroiditis due to bacteria and viruses. Symptoms can also be fever and headaches, as well as pain in the thyroid gland.
  2. Hypothyroidism. A reduced size of the gland indicates hypothyroidism and a decrease in the efficiency of the thyroid gland. When taking medications prescribed by a doctor, the package of which contains instructions, you can make up for the lack of hormone production.
  3. Inflammation is characterized by echogenicity above the norm and heterogeneity of the structure of the gland.
  4. Cyst. A rounded cavity with fluid inside, and clear edges and a normal structure on the outside - this is a typical description of a cyst. To find out if there are cancer cells in the cyst, the doctor may prescribe a puncture, that is, a collection of contents.
  5. Cancer tumors. Formations with high density and jagged edges. Enlarged lymph nodes may also indicate tumor growth. The tumor can be either benign (adenoma) or malignant (cancer).
  6. Diffuse-toxic goiter. Increased volume of the gland, mood swings, nervousness, weight loss are indicators of goiter caused by increased production of iodine-containing hormones from the gland.
  7. Nodular goiter. It can be felt by ordinary palpation. The seal is easily felt in the front of the neck. In the ultrasound picture, the goiter can be seen as a high-density focus with clear boundaries and healthy tissue.

But it should be understood that an ultrasound examination of the thyroid gland, the decoding of which is multi-stage and complex, can only be correctly read by a specialist who can also prescribe blood tests for hormones, sugar levels, general blood and urine tests.

Problems with the thyroid gland in modern life are quite common. Ultrasound examination, at the moment, is recognized as the most painless and safest method for examining the gland, and its location guarantees simplicity and convenience.

Ultrasound helps to detect the presence of diseases and disorders of the thyroid gland, as well as deviations in size from the required norm. All this helps to maintain the health of yourself and your loved ones.

Feeling of suffocation and a lump in the throat with pathologies of the thyroid gland

An attack of suffocation in pathologies of the thyroid gland

The feeling of suffocation, the sensation of a lump in the throat in case of thyroid gland pathologies is determined by a set of symptoms and factors:

  • an attack of excitement;
  • active labor;
  • exposure to chemicals:
    • medicines;
    • food additives.

The attack is accompanied by the following symptoms:

  • pressure in the throat when swallowing;
  • dryness, burning in the mouth;
  • sore throat, coughing;
  • easy suffocation with lack of air;
  • there is weakness, sweat comes out.

Causes

To determine the cause of the feeling of a lump in the throat, it is necessary to exclude the pathologies of the organs that are accompanied by this symptom:

  1. 1. Quincke's edema. This manifestation of allergy often causes a feeling of a foreign body getting into the larynx, difficulty breathing. A history of rashes confirms a tendency to allergies. It is necessary to urgently take a large dose of an antihistamine drug, call an ambulance.
  2. 2. Feeling of a lump in the throat can cause vegetovascular dystonia. Attacks are provoked by nervous experiences, weather changes. This disease is confirmed by the presence of the following symptoms: nausea; dizziness; apathy. Attacks are provoked by nervous experiences, weather changes.
  3. 3. Discomfort in the form of a burning sensation may be heartburn caused by the reflux of gastric juice through the esophagus into the lower pharynx. Frequent heartburn confirms acidity and gastritis. It is possible to alleviate the condition in this case by reducing the amount of salty, sweet, fried foods consumed.
  4. 4. The state of lack of air accompanies attacks of diseases such as asthma, SARS, pharyngitis and causes discomfort in the larynx.

Thyroid disease

Diseases, accompanied by a feeling that the thyroid gland is choking, are divided by endocrinologists into three types:

  1. 1. Thyroiditis.
  2. 2. Nodular goiter.
  3. 3. Diffuse goiter.

diffuse goiter

Pathology is easily determined by visual examination due to a significant increase in the volume of the thyroid gland.

The organ is located close to the skin of the anterior region of the neck, so its growth is imperceptible only with excessive deposition of fat in the neck.

Diffuse goiter is accompanied by the following symptoms:

  • discomfort while eating;
  • bouts of dry cough;
  • hoarseness of voice;
  • discomfort if clothes press on the throat.

In this disease, the entire tissue of the organ is affected, which leads to a violation of the synthesis of hormones. A decrease in thyroid hormones in the venous blood leads to hypothyroidism, manifested by:

  • weight gain;
  • tissue swelling;
  • shortness of breath;
  • bradycardia;
  • loss of eyelashes and eyebrows;
  • pallor and dry skin.

An excess of thyroid hormones is accompanied by thyrotoxicosis, causing:

  • weight loss;
  • sleep disorders;
  • tachycardia;
  • skin moisture;
  • anxiety;
  • hand tremor.

nodular goiter

This pathology leads to partial damage to the tissues of the thyroid gland, causing the formation of nodes.

A node is an increase in the structural unit of an organ - a follicle.

By the number of nodular formations, this pathology is divided into types:

  1. 1. Multinodular goiter - two or more nodules.
  2. 2. Solitary node - expansion of one follicle.
  3. 3. Tumor node - with the degeneration of the substance of the follicle into an oncological formation.
  4. 4. Follicular cyst - a large number of modified follicles (adenoma).

In the initial stages of the disease, the nodes do not cause concern. The feeling of a lump in the throat causes a significant increase in the size of the formation and is constantly present, in contrast to the occasional diffuse goiter. Join at the same time:

  • difficulty and pain in swallowing;
  • increased sweating;
  • rapid pulse;
  • weight loss;
  • disorders of the gastrointestinal tract.

An increase in the number of nodes and their size leads to disruption of the functioning of the thyroid gland, causing a failure in the production of hormones. Manifestations of hypothyroidism or thyrotoxicosis are added, as in diffuse goiter.

Thyroiditis

Any inflammatory process in the thyroid gland, regardless of the nature of the occurrence, is called thyroiditis.

Inflammation of the thyroid gland rarely causes a feeling of a lump in the throat, due to its location much higher than the esophagus. If for some reason the location of the organ is lower than the generally accepted one, this causes difficulty in swallowing.

Thyroiditis is classified into the following types:

  • subacute;
  • spicy;
  • chronic;
  • autoimmune.

Acute and subacute forms of thyroiditis cause complicated infectious diseases, which are characterized by:

  • increase in body temperature;
  • general weakness;
  • neck pain.

Autoimmune and chronic thyroiditis causes a deviation in the functioning of the immune system, which is hereditary. The immune system produces antibodies to thyroid cells. The result is chronic inflammation of the tissues of the organ, causing a violation of its functioning. The development of pathology is gradual, manifested by slight weakness.

Treatment of thyroid pathologies

If you manage to seek help from a specialist in time and confirm that the lump in the throat and suffocation causes the pathological process of the thyroid gland, then the prognosis of the condition is favorable.

In hyperthyroidism, thyreostatics are prescribed, which reduce the secretion of hormones caused by hyperactivity of the thyroid gland, and prevent the accumulation of iodine in the body. The patient is recommended a diet with a high content of proteins and carbohydrates.

For immunostimulation, multivitamin complexes containing a small amount of iodine are used.

Treatment of thyroiditis is aimed at suppressing progressive infectious inflammation, eliminating hormonal imbalance with a course of hormonal drugs.

The diet includes iodine-containing foods: lean meat, seaweed, fish, fresh fruits and vegetables. To relieve puffiness, wrapping with honey, a pressure compress is effective. Multivitamin iodine-containing complexes increase efficiency.

Infectious inflammation may be accompanied by the release of pus into the cavity of the thyroid gland. To prevent sepsis, pus is pumped out through a small puncture. If the feeling of squeezing does not go away, resort to radical measures - excision of the affected part. Failure to operate can lead to asphyxia (suffocation) due to partial blockage of the airways.

Removal of part of the thyroid gland or the entire organ entails permanent restrictions in human life:

  1. 1. Compliance with an individual diet.
  2. 2. Periodic monitoring of the production of thyroid hormones.
  3. 3. Systematic use of synthetic hormone replacement drugs.
  4. 4. Complete refusal of alcohol, smoking.
  5. 5. Prohibition on heavy physical work.

Removing an asthma attack at home

A mild symptom of suffocation, a coma in the throat will help to remove physiotherapy techniques that can be done at home:

  1. 1. Warming up the feet and hands by immersion in hot water.
  2. 2. Soothing massage of the back of the neck (you can do self-massage).

Strengthening the therapeutic effect is achieved by a course of procedures.

The use of folk remedies for feeling a lump in the throat and asthma attacks is used as a prophylaxis between courses of medical therapy. Tea from soothing herbal preparations containing valerian, motherwort, St.

The strength of immunity depends on many factors. The state of the thymus affects the level of the body's defenses and the ability to resist foreign agents. In case of malfunction of the thymus, viruses, pathogenic bacteria, pathogenic fungi spread freely through the tissues, and severe infectious diseases develop.

How dangerous is the defeat of the thymus gland in young children? What pathologies of the thymus are found in adults? What to do with diseases of the thymus? Answers in the article.

Thymus gland: what is it

For a long time, doctors cannot come to a consensus on which system to attribute the thymus to: lymphoid or endocrine. This circumstance does not diminish the role of the gland, which performs an active protective function. Animal experiments have shown that when the thymus is removed, foreign agents do not meet resistance, quickly penetrate the cells, and it is difficult for the body to cope with a dangerous infection.

The first 12 months after the birth of a child, it is the thymus that protects the body from the influence of pathogenic microorganisms. As it grows and develops, other organs take over some of the functions.

From the bone marrow, stem cells periodically move to the thymus, then the process of their transformation begins. It is in the thymus that the formation, "training" and active movement of T-lymphocytes - immune cells - take place. Differentiation in the tissues of the thymus makes it possible to obtain specific cells that fight foreign agents, but do not destroy the elements of their own body. When the thymus is disrupted, autoimmune pathologies develop, when the body perceives its cells as foreign, attacks them, which leads to malfunctions and severe lesions.

Where is the thymus located? Most likely, not everyone knows the answer to the question. An important organ, without which the production of T-lymphocytes is impossible, is mentioned less often than the thyroid gland or the pituitary gland, but without the thymus, the body becomes practically defenseless against the penetration of dangerous bacteria and viruses.

The thymus gland is easy to identify on x-ray, in the upper chest (dark spot in the upper mediastinum, just behind the sternum). With anomalies in the development of an important organ responsible for the strength of immunity, individual lobules grow into the tissues of the thyroid gland, occur in the tonsils, soft tissues of the cervical region, fatty tissue of the posterior (less often) or anterior (more often) mediastinum. Abberant thymus is detected in 25% of patients, in most cases females suffer.

Occasionally, doctors record thymus ectopia in newborns. Pathology occurs on the left side of the mediastinum, more often in boys. Cardiologists note: with ectopic thymus, 75% of patients have congenital heart muscle defects.

Functions

The main function of the thymus gland is the production of T-lymphocytes to protect the body. The thymus not only produces specific cells, but also selects them in order to destroy precisely dangerous microorganisms.

Other features:

  • production of thymus hormones (thymopoietin, IGF-1, thymosin, thymalin), without which the proper functioning of all organs and systems is impossible;
  • participates in the functioning of the hypothalamic-pituitary system;
  • maintains immune protection at a high level;
  • responsible for the optimal growth rate of the skeleton;
  • thymus hormones exhibit a nootropic effect, reduce the level of anxiety, and stabilize the functional activity of the central nervous system.

Important! Hypofunction of the thymus negatively affects the immune defense: the organ produces fewer T-lymphocytes or, with this type of pathology, the cells are not sufficiently differentiated. In children under one year old, the thymus is large; before the onset of puberty, the organ grows. Against the background of aging, the thymus gland decreases, in extreme old age, a specific organ often merges with adipose tissue, the weight of the thymus is only 6 g. For this reason, the strength of immunity in older people is much lower than that of young people.

Structure

The organ has a lobed surface, soft texture, grayish-pink tint. A connective tissue capsule of sufficient density has two lobes adjacent or fused to each other. The top element is narrow, the bottom one is wide. The name of the organ appeared against the background of the similarity of the upper lobe with a two-pronged fork.

Other parameters: width, on average, 4 cm, length of an important organ - 5 cm, weight - up to 15 g. By the age of 12-13, the thymus becomes larger, longer - up to 8-16 cm, weight - from 20 to 37 g.

Causes of thymus problems

In some patients, doctors detect congenital anomalies in the development of the thymus: the action of T-lymphocytes is aimed at destroying not foreign agents, but the cells of their own body. Chronic autoimmune pathologies adversely affect the patient's condition, the body weakens, at the same time, bacteria and dangerous viruses multiply freely in tissues after human infection. A constant intake of drugs is required to prevent serious consequences against the background of weak immunity.

Other causes of thymus dysfunction:

  • exposure to high doses of ionizing radiation;
  • genetic predisposition;
  • difficult environmental conditions in the region of residence;
  • non-compliance of the pregnant woman with the rules for taking medications, exposure during fetal development.

Diseases

With frequent colds, a sharp decrease in immunity in newborns, doctors recommend examining the thymus gland in children. It is this organ that is responsible for the level of the body's defenses at an early age. In severe lesions of the thymus, doctors recommend removing the problematic organ that does not produce healthy T-lymphocytes. With mild and moderate disorders in the structure and functioning of the thymus gland, a course of immunomodulators will be required to maintain the optimal level of immunity.

Pathological processes in the thymus occur both in childhood and in adult patients. Dysfunction is often combined with autoimmune lesions of the thymus. Damage to an important organ also occurs against the background of a malignant tumor process and hematological diseases.

Thymus diseases develop much less frequently than lesions of other organs that regulate the main processes in the body that produce hormones. Pathologies of the hypothalamus, ovaries, pituitary gland, thyroid gland are more common, especially in patients of the middle and older age category (40 years or more).

The main types of damage to the thymus:

  • benign and malignant tumors. Types: lymphomas, germinal formations, carcinomas. In childhood, the tumor process is rare, most cases of pathologies were recorded in women and men at the age of 40 and later. In rare cases, biologically benign neoplasms have areas of cystic necrosis;
  • congenital pathologies. DiGeorge's syndrome has several features: congenital hypoparathyroidism, malformations of the arteries, veins and heart muscle, aplasia of the gland with a lack of selection of T-lymphocytes. At an early age, the risk of death in children from tetany (severe convulsive seizures) is increased, as the child grows older, the child's body is faced with persistent and recurrent infectious diseases;
  • thymus hyperplasia. Neuromuscular pathology proceeds with a violation of the process of impulse transmission through myoneural connections from autoantibodies to acetylcholine receptors. With hyperplasia, lymphoid follicles appear in the tissues of the gland. Similar pathological changes develop in many autoimmune diseases: rheumatoid arthritis, multiple sclerosis, Graves' disease;
  • thymus cysts. Tumor formations most often do not show characteristic signs indicating a pathological process in the thymus, which complicates the timely detection of cysts. In most cases, cavities with mucous and serous contents are detected during surgical treatment. The diameter of cystic formations rarely reaches 4 cm, tumor-like structures are spherical or branching.

Treatment of pathologies of the thymus gland is a long process. Chronic autoimmune diseases cannot be eliminated, it is only possible to reduce the level of negative effects of T-lymphocytes on body cells. Taking immunomodulators, B vitamins increases resistance to infections, normalizes nervous regulation.

The thymus gland is an important organ of the endocrine system. With immunological disorders, you need to take drugs prescribed by a doctor to reduce the risk of destruction of healthy cells. If a child of the first year of life is often sick, it is necessary to check the condition of the thymus in order to exclude congenital autoimmune pathologies. Regular intake of vitamins, proper nutrition, preventive measures in the autumn-winter period, hardening help in strengthening the immune system.

In the next video, the specialist will tell you in an accessible way about what the thymus gland is and why it is needed in the human body, and will also instruct you on what to do if the doctor talks about an enlarged thymus:
