What are the symptoms of sputum poisoning?

Barium poisoning is a poisoning reaction that occurs when the body ingests a compound containing barium. Earthworms are more toxic to mammals than lead, mercury, and other metal elements, which are comparable to arsenic. The minimum lethal dose for adults is 12 mg/kg body weight and for children 8.8 to 15 mg/kg body weight. Typical symptoms of sputum poisoning include hair loss, gastrointestinal reactions, and nervous system damage. Hemorrhoids are usually left on the armor's armor. Earthworms have strong cumulative toxicity and can cause permanent damage to patients, including muscle wasting, permanent damage to the liver and kidneys. Ingestion of guanidine compounds by the human body can be caused by ingestion of guanidine-containing compounds, drinking of lanthanum-containing water sources, eating wolfberry fruits and vegetables, and occupational exposure. Treatment of sputum poisoning includes: using Prussian blue, sodium dimercaptopropionate, sodium thiosulfate and other drugs to promote sputum ion excretion; oral potassium chloride solution to promote sputum metabolism in the kidney; use of diuretics to accelerate sputum excretion; use of hemoperfusion therapy Adsorption of cesium ions etc. Occupational sputum poisoning is a legal occupational disease in the People's Republic of China.

Contact method and classification é“Š are widely used industrial materials. The lanthanum alloy contains many special properties. It is the raw material for producing corrosion resistant containers, low temperature thermometers, and superconducting materials. Some lanthanum compounds are sensitive to infrared rays and are important raw materials for the optoelectronic industry. Indole compounds can also be used to prepare insecticides, hair loss agents (antimony acetate) and the like.

Therefore, daily exposure to ingestion is an important factor leading to sputum poisoning. The guanidine compounds can be absorbed through the skin or absorbed through the hair follicles, respiratory tract mucosa and the like that spread over the body surface. Cases have shown that exposure to helium containing dust for 2 hours may result in acute hydrazine poisoning.

In addition, due to soil and drinking water pollution caused by mining and other reasons, it may also cause residents to ingest indole compounds through the diet, resulting in acute or chronic sputum poisoning.

Most lanthanum salts are colorless, odorless and have good solubility. Therefore, eating and poisoning are also one of the ways in which guanidine poisoning patients can contact guanidine compounds.

According to the history of exposure and development of the disease, sputum poisoning can be divided into acute sputum poisoning and chronic sputum poisoning. Acute sputum poisoning is a poisoning reaction caused by large intake of sputum in a short period of time. Most of the exposure routes are oral, mainly manifested in the nervous system and digestion. Systemic symptoms; Chronic sputum poisoning is generally caused by long-term occupational exposure. Symptoms are similar to acute sputum poisoning, but the course of disease is longer and clinical manifestations are more moderate.

Symptoms and Diagnosis As mentioned above, thorium poisoning generally has more typical symptoms of nervous system, digestive system, and hair loss. However, due to the rare occurrence of sputum poisoning, it is often overlooked, leading to misdiagnosis.

Symptoms of hair loss and skin lesions Hair loss is a specific symptom of sputum poisoning. All sputum poisoning patients will have hair loss after a poisoning reaction. Not only hair loss but also beards, armpit hair, and pubic hair will fall off, but eyebrows usually do not fall off. It has been reported that alopecia symptoms generally occur within 1 to 3 weeks after acute sputum poisoning, and hair loss occurs within the shortest time within 4 days. In case of hair loss caused by terrible poisoning, the hair will fall off into bundles and cause alopecia areata. This type of hair loss is usually reversible. Hair usually begins to regenerate around 4 weeks after the sputum poisoning is cured, and it completely recovers after 3 months. However, it has been reported that severe sputum poisoning can lead to permanent hair loss.

Symptoms of the nervous system can cause peripheral neuritis. The patient begins to numb both lower extremities within 12 hours to 1 week after poisoning, and then begins to feel pain from the end of the foot, and spreads as the disease progresses, touching the skin of the patient. This creates an unpleasant burning sensation. Subsequently, the patient will develop dyskinesia, feel weakness in the lower limbs, and eventually develop muscle atrophy.

Sputum will also affect the optic nerve, leading to posterior optic neuritis and optic atrophy and loss of light reflex in the macula. Cockroaches can also cause paralysis of the ophthalmoplegia and sagging of the upper eyelids. In addition, due to the effects of hemorrhoids, the patient usually has white turbidity in the lens. These factors eventually lead to vision loss or even complete loss of light perception in patients with sputum poisoning.

Cockroaches also affect the central nervous system. Patients may experience headaches, sleep disturbances, anxiety and even personality changes. Some patients may also develop rickets-like symptoms, and wounding or self-injury may occur.

Digestive System Symptoms Gastrointestinal symptoms occur early in patients who are taking orally taking a compound with oral contact. These symptoms include nausea, vomiting, loss of appetite, and abdominal pain. In addition, patients often appear constipation, with the development of the course of disease, late for diarrhea; some patients can see stomatitis, glossitis, gingival erosion, gastrointestinal bleeding and other symptoms. Toxic hepatitis may also occur in some serious cases.

Diagnosis depends on the characteristics of symptoms can be diagnosed with poisoning.

Hair loss, sensitivity to lower limb numbness and pain caused by peripheral neuritis, and symptoms of nausea, vomiting, and abdominal pain all occur at the same time, which is an important clue to identify cesium poisoning. In addition, there will be white stripes on the nails of patients with sputum poisoning, known as Mie's line, which is an important basis for diagnosis of sputum poisoning.

Asking the patient's medical history is also an important basis for diagnosing sputum poisoning. Patients with sputum exposure history or exposure to sputum may present sputum poisoning in patients with signs of sputum poisoning.

The detection of blood, urine hair and other biological samples is the basis for the final diagnosis of sputum poisoning. The urine test is the most important. Since the sputum is almost completely metabolized by the kidneys in the body, the concentration of sputum in the urine directly reflects the patient's contact with the sputum and the condition of poisoning. The urine concentration of more than 0.015 mmol/L can be diagnosed. Poisoning.
