Ascaridosis is the most frequent helminthium, distributed throughout the earth
The pathogen - Human Ascaris (Ascaris Lumbricoides), round
Helmint. Adult individuals have a spindle-shaped. Alive or just
Standing from the intestine ascaris of reddate yellow color, after death become
Whitish. The male is noticeably less females, its length is 15-25 cm and the rear end of the body
Hooked hooked. The female has a straight body with a length of 25-40 cm and 3-6 mm in thickness.
A person in whose intestines parasitize females and males ascaris is
The only source of invasion. Mature Askarida female is able to postpone
245000 eggs per day. Unripe helminth eggs are highlighted in the external environment,
their ripening occurs with a favorable temperature and humidity.
The larva ripens inside the egg for 9-42 days at an optimal temperature - 24-30° WITH. Mobile larva, formed in the egg, makes a molt and only
After that, it acquires an invasive (infecting) ability. Human infection
occurs when swallowing mature eggs, vegetables are the main value on the surface
which are soil particles. A certain danger to distribution
Askaridoza represent gardening and garden areas, where the soil fertilizer is sometimes
Used human feces.
After swallowing and getting into the small intestine, larvae go out of mature eggs,
which are introduced into the walls of the intestine and penetrate the blood vessels. With current
Blood larvae fall into the liver and light (migration stage 6-8 weeks), and
They can also get into the brain, eyes and other organs. In light larva
actively goes to alveoli and bronchioles, moves on small and large bronchoms
With the help of the eyelet of the epithelium before the rotogling, where the larvae is swallowing
With mocroid. Finding back into the intestines, the larva for 70-75 days reaches
puberty (intestinal stage, after 8 weeks after infection). Duration
The life of adult ascarides reaches the year, after which her death and together
With the feces she is removed outward.
Symptoms and Askaridoz
Askaridoz manifestations depend on the localization of parasites.
In the clinical course of ascarideosis, two phases are distinguished - early (migration) and
Late (intestinal). In the migration phase of ascarisidosis manifestation of the disease
expressed, it proceeds imperceptibly. Sometimes the beginning of the disease is manifested with pronounced
Awildness, a dry cough appears or with a slight amount of mucous
sputum, less often mucous-purulent. Motica sometimes acquires orange color
and has a small blood admixture. Body temperature is usually normal or subfebrile
(up to 38° WITH). Very characteristic of this stage changes on the skin, which often
manifest themselves as wretched and small bubbles with transparent content on
Tasters and feet.
With a radiographic study of the lungs, rounded, star,
Polygonal infiltrates. Infiltrates can be both solid and multiple,
Detected in one share or all over light.
The intestinal phase of ascarides is associated with the stay of helminths in the intestine. Sometimes
It proceeds without pronounced symptoms, more often patients celebrate increased
fatigue, change in appetite (lower), nausea, sometimes vomiting, pain in
stomach. Pains occur in the top of the abdomen, around the navel or at the bottom right
and worn gravity. Some patients have diarrhea, others
constipation or alternation of diarrhea with constipation. From the nervous system during ascariasis
Common headache, dizziness, increased mental fatigue. Observed
Restless sleep, night fears, dizziness attacks, hysterical seizures,
Causes. In some cases, changes from the eye - expansion
pupils, pupils of different sizes, light, reduction of visual acuity. From side
Cardiovascular system In part of patients with ascariasis, there is a decline
Arterial pressure. Sometimes the stay of Askarid in the intestine becomes the cause
The emergence of bronchitis and bronchial asthma.
Complications of Askaridoza
Intestinal obstruction, which is caused by closing the lumen
intestines tangle from ascarid; Askaridoznaya appendicitis; Ascaridosis of the liver and bile
paths (cholangogeatitis) with development; Inflammation of biliary tract - purulent
cholangitis and multiple liver abscesses; Askaridosis of the pancreas with development
acute pancreatitis; Askarid hit in respiratory tract with suffocation
Diagnosis, treatment and prevention of ascarideosis
In the migration phase - the detection of ascaride larvae in sputum;
Detection of specific antibodies in the blood using immunological reactions.
In the intestinal stage of the disease, the main method is the study of feces on
Eggs Askarid. If the eggs are detected in duodenal content, then it can
testify to the presence of parasites in bile and pancreatic ducts.
For the expulsion of Askarid, piperazine adipient, Pyrantel
and levamizol (decaris). Effective tool with ascariasis is oxygen,
it is introduced through the gastric probe in the morning on an empty stomach or 3-4 hours after breakfast
2-3 days in a row. The amount of oxygen per session is 1500 ml, after administration
Oxygen patient must lie 2 hours. Oxygen contraindicated with ulcerative
Diseases and inflammatory diseases in the abdominal cavity.
Piperazine Adipinat is prescribed 2 times a day in 1 hour before or after 30-60 minutes
After eating for 2 days in a row at a dose of 1.5-2 g at the reception, the daily dose is
Currently, instead of piperazine, it is preferred to assign inward once
Levamizol (decaris) at a dose of 150 mg after meals. Pyrantel (Combarnian, Helmintoks,
Nemocide) is prescribed inside during or after eating in a dose of 10 mg / kg body weight.
Tablet before swallowing should be carefully checked.
It is necessary to protect the soil of vegetable gardens, gardens and berries
from pollution by feces, thoroughly wash your arms before eating, wash and boil
boiling water vegetables and fruits before use.
