An immunologist spoke about the combination of organ damage with COVID-19

A little about biopsy

Lymph node biopsy has two main goals:

• Detection of cancer;
• Detection of the infectious process in the lymph nodes.

Lymph nodes are an important element of the body's immune system, acting as “barriers” to the lymphatic vessels.

Lymph penetrates all internal organs and tissues of a person through lymph vessels. But along with lymph, unwanted bacteria and cancer cells can penetrate. And here the lymph nodes retain cancer cells. Such lymph nodes are called regional.

As the cancer develops, it can give metastases, which primarily affect nearby organs. Oncological diseases of the lungs and lymphoproliferative diseases more often metastasize to the supraclavicular and cervical lymph nodes.

Diagnosis of lymph nodes makes it possible to understand whether there are pathogenic cells in them.

In most cases, manipulation is carried out using a needle and syringe. This process is called a needle aspiration biopsy.

By enlarging, lymph nodes often signal the presence of pathologies, some of which are:

• The lesion is metastatic;
• Lymphomas;
• Sarcoidosis.

Using diagnostic techniques, the doctor has the opportunity to determine the optimal treatment tactics. The technique is highly informative, but it is necessary to remember: a positive result of the study remains so, but a negative one may also be erroneous.

The latter occurs more often due to the fact that pathogenic cells simply do not enter the removed material (biopsy).

After the procedure, the biopsy specimen is examined histologically or immunohistochemically.

The problem is that the biopsy obtained during puncture manipulation is not enough to conduct these studies.

An excisional lymph node biopsy is a procedure to remove the lymph nodes. It is performed through small incisions. As a result of the intervention, the lymph node is completely removed, using local anesthesia for pain relief.

After removal of the lymph node, it is sent for histological examination.

This approach makes it possible:

• Detection of lymphomas;
• Determining the type of disease;
• Determination of optimal treatment tactics.

If pathogenic cells are identified as a result, surgical intervention is used.

What antibiotics can you take during pregnancy?

Penicillins are best for pregnant women

Penicillins are antibiotics that are most often used during pregnancy and lactation. A pregnant woman can take penicillin even in the first trimester if there is a medical reason for doing so.

For respiratory, urinary, ear, and nasopharyngeal infections, cephalosporins, Amoxicillin and Ampicillin (beta-lactam antibiotics) are often used. Erythromycin is also one of the antibiotics allowed during pregnancy.

Indications and contraindications

In most cases, the procedure is indicated to identify cancerous tumors.

Thus, in case of skin melanoma, the sentinel lymph nodes located in close proximity to the tumor site are examined. This helps determine the stage of the disease, as well as determine treatment tactics.

Suspicion of lymphoma is another indication. When the lymph node is removed and examined, the doctor has an idea of ​​the exact type of pathology, which, in turn, is crucial when choosing treatment tactics.

The procedure may be indicated for the purpose of identifying non-oncological diseases, such as tuberculosis, lymphadenopathy, sarcoidosis, etc.

There are a number of other indications for conducting research:

• Lack of results in long-term treatment of enlarged lymph nodes;
• Enlarged lymph nodes can be felt during palpation, but there is no pain, there are signs of intoxication;
• Lymph node size > 1 centimeter.

Any intervention has a number of contraindications. In the case of the described technique, they become:

Core biopsy of the breast

• Suppuration of the lymph nodes and adjacent tissues;
• Poor blood clotting;
• Curvature of the cervical spine, some others.

Causes of development of lateral neck cyst

A lateral neck cyst or branchiogenic tumor (the name of the disease comes from the Greek word “kystis” - bubble) refers to congenital benign tumor formations, which is a consequence of pathological embryonic development of the fetus. Long-term studies indicate a direct connection with abnormal intrauterine development of the fetus in the early stages of pregnancy.

Already from the fourth week of pregnancy, the formation of the gill apparatus in the embryo occurs, consisting of 5 pairs of cavities or “gill pockets”, gill slits and arches connecting them, involved in the development and formation of the structures of the child’s head and neck. With normal anatomical development of the fetus, the gill pouches gradually become overgrown, but in some cases, they persist and form various types of cysts (lateral, median).

How to do it

The patient needs to prepare for the procedure in advance.

To do this, he must pass urine tests prescribed by the doctor. When examining the cervical lymph nodes, an X-ray examination may be prescribed. It is necessary to exclude kyphosis of the spine.

Excisional biopsy is otherwise called open: it requires access to the lymph node. The manipulation is carried out in the operating room.

Before the intervention, the required area is treated and numbed. As we have already noted, local anesthesia is more often used; in some cases, intravenous anesthesia may be indicated.

In the projection of the lymph node, the doctor makes an incision in the skin, after which he separates the tissue and, having reached the lymph node, removes it.

After completion of the manipulation, the incision is sutured. The duration of the entire procedure can range from ten minutes to half an hour. It all depends on the complexity.

Types of lymph node cancer

In addition to division by type of lymphoma, lymph node cancer is classified according to the location of the lesion. Based on this criterion, oncology of different types of lymph nodes is distinguished:

• axillary;
• cervical;
• pulmonary;
• ileal;
• supraclavicular;
• inguinal

In percentage terms, cancer of the lymph nodes most often occurs in the groove area (35%), followed by the neck (31%) and armpits (28%). Other localizations of oncology account for 6%. The most favorable prognosis is observed for cancer of nodes in the groin, armpits and under the jaw.

What after?

The patient receives doctor's recommendations regarding the recovery period. Usually this period proceeds quickly and easily and does not require serious restrictions.

The results of the study are ready a week to ten days after the procedure. This is quite long because the process of preparing sections is labor-intensive. In addition, sometimes there is a need to clarify the diagnosis using immunohistochemistry.

Having received the conclusion from the laboratory, the doctor makes a final diagnosis and prescribes the necessary treatment.

Clinical case in the larynx department of the Federal State Budgetary Institution National Medical Research Center of the Federal Medical and Biological Agency of Russia

Patient M. , 26 years old, on June 20, 2016, sought medical help from specialists from the Department of Laryngeal Diseases of the Federal State Budgetary Institution National Medical Research Center for Medical and Biology of the Federal Medical and Biological Agency of Russia with a complaint about the presence of a mass on the right side of the neck. According to the patient, the formation appeared in September 2015, and gradual growth was noted. After an MRI examination and ultrasound of the neck, a diagnosis of “lateral neck cyst” . On the right side of the neck, the contours of the cyst are visualized from the mastoid process of the temporal bone to the clavicle; upon palpation it is dense, the surface is smooth.

On June 21, 2016, the patient underwent removal of a benign neck tumor.

Size of removed tumor: 20 cm by 6 cm

In the postoperative period, patient M. received antibacterial therapy, the suture was removed on the 7th day.

She was discharged on June 29, 2016 with improvement.

Rules for taking antibacterial drugs

Antibiotics are drugs that must be consulted with your doctor before using them. Self-medication quite often leads to the development of side effects.

Also, patients often cannot choose the optimal drug for a particular pathology, so therapy in many cases does not lead to a cure.

Only a qualified doctor can accurately assess the general condition of the patient, carry out the entire necessary set of diagnostic measures and make a diagnosis of inflammation of the lymph nodes.

Antibiotics for inflammation of the lymph nodes are prescribed in a course. The duration of therapy for this pathology lasts at least 5 days. Maximum it can be 3-4 weeks. You cannot stop antibiotics on your own, as this can lead to progression of the disease and the development of septic complications.

If the patient for some reason missed taking an antibacterial drug, then he needs to take a new dose of the medication as quickly as possible, and then continue therapy as usual. You can only take antibiotics with water. It is prohibited to use other drinks for this purpose - soda, dairy products, strong tea or coffee, since they affect the absorption of the drug into the human body when taken orally.

Often, for lymphadenitis, a stepwise method of using the drug is used. Very often, patients with this pathology are hospitalized in surgical hospitals. Therefore, antibiotic therapy is prescribed to them in parenteral form for intravenous or intramuscular administration. Subsequently, after discharge, they are prescribed the same antibacterial drug, but in the form of tablets or capsules.

What antibiotics are prescribed for children?

Respiratory tract infections are one of the most common causes of lymphadenitis and referral to a pediatrician. Most infections that are accompanied by lymphadenitis are caused by respiratory viruses. Antibiotics are too often inappropriately prescribed to children with respiratory infections.

Due to improper use of drugs, children may experience abdominal pain, nausea, vomiting, and diarrhea. In very rare cases, severe complications occur - enterocolitis, acute liver failure or severe skin reactions leading to erythema multiforme.

Inappropriate use of antibiotics creates additional problems. Increased and uncontrolled use of antibiotics is associated with the risk of development of antibiotic-resistant strains.

Antibiotics are absolutely necessary in the following cases:

• Bacterial pneumonia.
• Meningitis.
• Urinary tract infections.
• Quinsy.

For respiratory tract infections, watchful waiting is recommended. For colds, parents should first monitor their child for 48 hours and not use antibiotics, as 80 to 90% of all infections resolve spontaneously. If your child continues to have a fever, you should see a doctor.

For acute middle ear infections, treatment depends on the patient's age. If a young patient is under 6 months of age, he or she should be given an antibiotic immediately because the risk of serious infections and later relapses is higher at this age. In children from six months to 2 years of age, treatment is not always necessary. A child over 2 years old also does not require treatment in all cases.

Amoxicillin

Amoxicillin is a broad-spectrum antibiotic belonging to the penicillin class. It is the most widely used and is used to treat respiratory tract infections in children - tonsillitis, ear, nose and throat infections, Lyme disease, bone inflammation and blood poisoning. It is also prescribed for preventive purposes before surgery.

Amoxicillin is a very well tolerated antibiotic. It is available in different dosages - 250, 500, 750 or 1000 milligrams. The doctor indicates the dosage depending on the disease, age and weight of the child. It is recommended to take the medicine with food. Children are advised to maintain good oral hygiene, otherwise the medicine may cause yellowing of the teeth.

Cefuroxime

Cefuroxime is an alternative to Amoxicillin and is therefore considered a second-line treatment. Cefuroxime is effective against streptococci, pneumococci, staphylococci, which are often the main cause of inflammation in the mouth and throat. The drug is also used for respiratory infections, such as chronic bronchitis or pneumonia, infections of the ear, nose and throat. It is also used for kidney and urinary tract infections.

Cefuroxime is better tolerated than Amoxicillin. 10 in 1,000 children may experience dizziness, joint swelling, phlebitis, pneumonia or headache. Skin reactions, hepatitis or jaundice are rare. 10 out of 10,000 children develop hallucinations, nervousness and anxiety.
