Problem description:

My son is two years old and eight months old. He usually eats a lot of food and snacks. He should be strong and fat, but he is neither strong nor afraid. I don't know why. Some people say that he won't gain weight if he has roundworms. If he really has ascaris in his stomach, how can he be treated? What else can he do to see that there is a worm in his stomach? Are there any symptoms?

Analysis:

1. Ascaris lumbricoides larvae develop urticaria, fever, cough and lung inflammation during the * * * phase in the body; There are anorexia, indigestion, pain in the right upper abdomen, hepatomegaly and abnormal liver function. Bacteria brought by larvae can cause multiple liver abscesses and liver tenderness. The total number of white blood cells increased and eosinophils increased. As larvae enter the brain, individual children may cause convulsions or meningitis.

2. Adult ascaris lumbricoides can secrete toxins in the small intestine, excrete wastes and absorb nutrients in children. The common symptoms are paroxysmal abdominal pain around navel, soft abdomen, like rubbing and refusing to press; We call this phenomenon "pica" because we have a bad appetite, and some people like to eat things they shouldn't, such as dregs, clods and plastic bags. Because the normal digestion and absorption function is affected, it will cause malnutrition and anemia. It can also lead to listlessness, irritability and gnashing of teeth at night.

3. Adults usually settle in the small intestine, and when the environment is not suitable, they will flee everywhere, thus causing a series of serious symptoms and even life-threatening. For example, when children have a fever, ascaris will run around, causing severe abdominal pain, vomiting and ascaris. When worms get tangled up, they will block the intestines, causing roundworms to block up. Ascaris can drill into biliary tract when it sees the hole, which can cause biliary ascariasis. The condition is serious, and the child is crying and sweating because of abdominal pain. If ascaris enters the appendix, it will cause ascaris appendicitis and severe pain in the right lower abdomen. Re-drilling from the appendix can lead to dangerous diseases such as peritonitis.

How to find children with ascariasis?

1, often with unexplained diarrhea, constipation or abdominal pain (mostly around the navel).

2, poor appetite, do not want to eat and often want to eat sweet snacks, or have a good appetite but lose weight.

3, sometimes headache, excitement and poor spirit, inattention, slow response.

4. I often drool or grind my teeth when I sleep at night.

5, impatient.

6. There will be "insect spots" on children, and there are generally five kinds:

(1) erythema appears on the tongue surface, which is characterized by neat and round edges and often protrudes from the tongue surface. The location of erythema is uncertain and the number is different.

(2) Particles appeared in the mucosa of the lower lip, mostly small papules the size of gray needles, and the number varied.

(3) Blue spots appear on the sclera, which are triangular, round or half-moon.

(4) White spots appear on the face, mostly round, with neat edges and pale white in the middle.

(5) Flocculent white clouds appear on the nails.

These spots can appear alone or in combination.

7. I like picking my nose.

Children with ascaris may not all have the above symptoms, but there are at least 2-3 kinds. If you find that your child has the above symptoms, you should doubt whether you have this disease and need to go to the hospital for stool examination.

How to prevent and control ascariasis in children?

To prevent this disease, it is necessary to educate children to develop the habit of cleanliness, wash their hands before and after meals, chew their nails frequently, do not bite their nails, suck their fingers, drink raw water and eat cold and unclean food. In addition, we should pay attention to environmental sanitation and do a good job in feces disposal. If you have ascariasis, you can take Quyuanling, about one tablet a year, and take it two nights; Or Baota sugar, take two pills a year, two nights. One deworming may not achieve the goal of extermination. If the stool is positive again after one month of treatment, take another insect repellent. At present, the wide application of sausage in Chongqing has a certain effect. If there are complications, they should be sent to the hospital immediately.

Ascariasis is a parasitic disease of ascaris lumbricoides in human small intestine. More common in children aged 5 ~ 15. Mild cases are asymptomatic, severe cases have digestive tract symptoms and malnutrition, and severe cases cause biliary ascaris or ascaris intestinal obstruction.

Ascaris lumbricoides is the largest intestinal worm with milky white or pink adult and slender head and tail. Females lay eggs in human intestines, laying about 200,000 eggs every day. Eggs are excreted with feces and develop into infected eggs at a suitable temperature.

After children eat vegetables or fruits infected with eggs, some eggs are killed by stomach acid, and some hatch into larvae in the small intestine. Larvae pass through intestinal wall, small blood vessels, portal vein, heart and lung, trachea, throat and esophagus in turn, and develop in small intestine.

Grow into an adult. Symptomatic people may not show the symptoms of "ascaris infection" after being infected with ascaris, but umbilical cord may appear in children and infirm people.

Pain around or inside the upper abdomen can recur, accompanied by loss of appetite, nausea and vomiting; Children are often inattentive, crying, grinding their teeth at night, dreaming, itching, recurrent urticaria and white spots on their faces, which is serious.

Malnutrition, mental retardation, developmental disorder, sallow and emaciated, etc. Sometimes worms or stools with ascaris can be vomited, or ascaris can be found in stools. Ascaris eggs can be seen under the microscope, and eosinophils can be seen in blood routine.

The commonly used medicine (1) albendazole (Echongqing) is a broad-spectrum insect repellent, which can be used for adults and larvae of SINONOVACULA constricta, SINONOVACULA constricta, trichuris and hookworm.

It has good curative effect, can kill the eggs of SINONOVACULA SINONOVACULA and Trichinella spiralis, can interfere with the intake of glucose by worms and inhibit the growth and reproduction of worms, and is suitable for mixed infection of various nematodes. A single dose of 400mg, the cure rate is as high as 100%.

(2) Thiopyrimidine (insecticide): It can block the neuromuscular function of parasites and make worms contract first and then numb.

Arthralgia, stopping exercise, is faster and better than piperazine. Children weigh 5 ~ 10 mg per kilogram, and take it before going to bed for 2 consecutive days.

(3) Piperazine citrate (Quyiling): It can paralyze the muscles of worms, so that they can't adhere to the intestinal wall and creep with the intestine.

Ascaris is not excited before paralysis, so it is safe. Children often eat sugar ingots (six-one Baota candy)

), 0-day/kg body weight 100 ~ 160mg, or 1 ~ 3 years old 1 times 1.0 ~ 1.5~2g, 4 ~ 6 years old/kloc-.

2 ~ 2.5g, 3g over 9 years old, taken immediately before going to bed for 2 days, generally without laxatives. (4) Levamisole: It can affect the anaerobic metabolism of worms, paralyze them, prevent worms from moving and prevent gallstones.

The attack of roundworm. Children take 2 ~ 3 mg per kilogram before going to bed. 1 week can be repeated 1 time. Traditional Chinese medicine can make a gentleman stir-fry without burning, and the total amount of children should be calculated according to the age of 1g per week, which should not exceed 1g, and should be chewed before going to bed.

If swallowed continuously for 3 days, it can be used repeatedly.
