Lymphadenitis - inflammation of the lymph nodes.The causative agents are staphylococci, streptococci, spreading through the lymphatic pathways from the nearby foci of inflammation.
Lymphadenitis develops due to lymph node infection by various microorganisms, the most common cause is Staphylococcus, Streptococcus, and various types of diplococci (Pneumococcus), Pseudomonas aeruginosa and Escherichia coli.Immediate increase in lymph node is due to accumulation of inflammatory cells in the reaction zone, wherein the microorganism is detected.In most cases, these microorganisms enter the lymph node through the lymph vessels to the lymph current from the infected area of the body, the so-called primary focus of infection.This may be a purulent wound, localized on the surface of the skin, purulent-necrotic inflammation of the hair follicle or a boil.
Hematogenous route of infection (through the blood) occurs just as often as a consequence of limfagenny and focus of infection in the internal organs (infla
more rare pin pathogen transmission path directly in contact infectious material and lymph node tissue.Perhaps the penetration of bacteria directly into a lymph node when it is wound.In such cases, it lymphadenitis acts as a primary disease.
Once in the lymph node, the microorganism begins to send the products of its vital surrounding tissue, causing inflammation and further tissue and purulent meltdown.The changes in the surrounding tissue can restrict inflammation serous or purulent go in to form a phlegmonous adenitis.
pain in the inflamed lymph node swelling, redness of the skin.On palpation determined enlarged, oval, painful knots, single or whole groups of them.With early treatment and the elimination of the main focus of the process is subjected to reverse development.In more severe cases, the symptoms of intoxication appear: fever, fever, severe general condition, and the local way of abscess or cellulitis.
Lymphadenitis in children proceeds rapidly with high fever, malaise, loss of appetite, sleep disturbance.Possible complications can be severe generalization of infection with sepsis.
lymphadenitis develops in children quite active and can be acute or chronic.The acute form of the disease often makes itself known by the following features:
- fever (38 ° C and above),
- loss of appetite,
weakness and malaise,
intoxication (a painful condition caused by the action of the body substances,coming from outside (microbial toxins) or harmful substances produced in the body) in most small,
severe swelling (with cervical lymphadenitis),
severe pain in places of enlarged lymph nodes,
When purulent lymphadenitis area of inflammation may be red.
manifestation of the chronic form is the swelling of the lymph nodes, which can be detected by palpation (palpation).In this case, nodes slightly painful and normal body temperature.
If any of these symptoms you urgently need to show the child to the doctor.In no case do not set the diagnosis yourself and do not spend any therapeutic action.Only a specialist can confirm the presence of the disease and determine its type.That is the type and specifics will depend on the course of lymphadenitis and its treatment.
The only way you can help your child to the doctor's arrival, it's cool inflamed area with the help of ice.
Acute lymphadenitis begins with severe pain and swelling of the lymph nodes, which is not rarely leads to restriction of mobility of the body parts, next to which was formed lymphadenitis.Man begins to disturb the constant, dull or aching headache, there is a general weakness may malaise, fever.
serous lymphadenitis violates the general condition of the patient.It appears dull pain in the regional lymph nodes;the latter can be increased sufficiently thick compared to the healthy and slightly painful on palpation, the skin over the affected lymph nodes are not changed.With further progression of the inflammatory response in the lymph node, lymphatic tissue destruction occurs with development of purulent fusion and the formation of necrotic tissue.
purulent lymphadenitis causes pain that is sharp, sometimes twitch nature.The skin over the inflamed lymph node hyperemia (has a bright red color, indicating inflammation), pain during palpation revealed.If even with serous lymphadenitis lymph nodes are not merged in the early stages of each other, they continue to merge with each other and surrounding tissues become immobile.
chronic nonspecific lymphadenitis is the result of long-term chronic untreated infection.Chronic lymphadenitis may occur without obvious symptoms at all or does not manifest itself.Usually it is a little low-grade fever of about 37 degrees C, to which a person eventually gets used and does not notice slight swelling in the area of the affected lymph nodes.
phlegmonous adenitis , which is formed by untreated purulent lymphadenitis determined diffuse flushing of the skin, tight, without clear boundaries edema with areas of softening.The body temperature rises to high numbers, there is a fever, expressed heart palpitations, headache, marked weakness.Until this state, the disease is not necessary to bring, because it can lead to severe complications...
Treatment Bed rest, locally warmer, ointment compresses, exposure lamp solljuks, etc. If there are signs of purulent fusion of the inflamed site and the development of cellulitis shows the operation - opening, followed by treatment as in abscess.
Timely etiotropic treatment lymphadenitis avoids the spread and generalization of the process.The end result of chronic lymphadenitis may be scarring of the lymph node with connective substitution lymphoid tissue.In some cases, it may develop a violation of lymphatic drainage and lymphedema.
Prevention lymphadenitis requires prevention of micro traumas, infections of wounds and abrasions, skin abrasions.You also need timely treatment foci of infection (sore throat, dental caries), autopsy purulent formations (felon, boils).
rules preventing children:
- just visit the pediatric dentist for treatment of caries and its complications,
- being treated stomatitis, rhinitis, otitis, boils and other diseases until the end,
- take care that the child did not arisedamage to the mucous membranes of the mouth and skin,
- Protect the child from acute respiratory viral infections.
