Medically acute How to divide subacute and chronic 20

In different diseases, the division of acute, subacute and chronic is completely different.

Acute means that the condition is very urgent, it comes quickly, the pain is obvious, and if it is not immediately, it may cause serious complications such as aggravation of infection or perforation, bleeding, and even death.

Chronic means that the condition is not so urgent, it is slow, and the pain is not very serious, and it will not be life-threatening for the time being.

For example, acute cholecystitis and chronic cholecystitis, acute cholecystitis is very obvious pain in the right upper abdomen, the patient is cramping and accompanied by nausea, vomiting and fever, the examination can find obvious swelling of the gallbladder, if not actively carry out **, there may be serious complications such as gallbladder perforation.

Chronic cholecystitis is manifested by a faint pain in the right upper abdomen, which is generally relieved after rest or symptomatic **, and there is no need to rush to surgery for the time being.

Infectious diseases, acute is generally infected with the virus within 6 months of showing clinical symptoms as acute, more than 6 months is chronic, acute is generally within 2 weeks, the course of the disease is not more than 3 weeks: subacute 15 days to 26 weeks.

Leukemia, acute refers to the cessation of leukocyte differentiation in the early stage, and chronic refers to the cessation of leukocyte differentiation to the late stage. Neither white blood cell function normally.

Hello! The doctor replied: In different diseases, the division of acute, subacute and chronic is completely different.

If it helps you, hope.

Sub-disease is between health and disease, and the self-feeling group slows down to discomfort and discomfort, and various symptoms that cannot be diagnosed as a disease appear, which belongs to the stage of minor illness and the disease of desire, which is called the stage of "sub-disease".

"Sub-disease" is not only a new term, but also the concept of "curing diseases before they occur" that has existed in traditional Chinese medicine for thousands of years. It is a more accurate expression of the state of human health and disease, and it is more warning of people's health status.

What is the difference between a chronic disease and an acute disease.

1. Seeking medical attention too late. Many patients do not pay attention to the early symptoms of the disease, such as fever, cough, wheezing, abdominal discomfort, indigestion, etc., and by the time of the first visit, the disease has entered the chronic stage. This reminds people that they should pay attention to their health status at ordinary times, and if they find abnormal signs, they should seek medical attention in time and be reasonable**.

2. Irregular. This is a common cause of the change from acute to chronic disease. Healing is like fighting a war, and the "enemy" (pathogen) must be completely eliminated before it can be cured.

Many people mistakenly believe that they are cured when their symptoms improve and disappear temporarily after taking the drug, so they stop the drug or reduce the dose prematurely. As everyone knows, this is tantamount to staying behind closed doors, so that pathogens are latent in the body, and they will come out again to make waves when they have the opportunity. ** Incomplete, or premature discontinuation of the drug, insufficient dosage, will make the disease chronic.

3. Insufficient rest time. The evolution of acute disease into chronic disease is also related to the patient's lack of attention to rest and overwork. Common such as acute tuberculosis, patients must have sufficient rest in the acute stage, increase nutrition, in order to reduce the burden on the lungs, reduce the consumption of the body, improve the ability to resist the disease, it is possible to ** faster.

Otherwise, it will inevitably lead to a decrease in the body's disease resistance, and it will be difficult to achieve results with medication, thus gradually turning into chronic. This can also lead to worsening of the condition and serious complications.

Fourth, the nutrition is unreasonable. Nutrition is an indispensable condition for patients. After the disease, due to the depletion of the disease itself and the loss of appetite, the body needs more nutrients than usual.

Therefore, while taking medication, it is necessary to find ways to rationally adjust the diet according to the patient's condition. For example, when suffering from acute hepatitis, if the nutrition is insufficient for a long time, it is not easy to **, and it is easy to turn chronic.

Fifth, the mental burden is too heavy. After suffering from an acute illness, if the patient's mental state is not good, excessive tension, anxiety or pessimism and disappointment, it will often affect the curative effect and prolong the course of the disease and become chronic.

Most chronic diseases are acute, so it is fairly easier to be acute than chronic**.

Acute illness is a symptom that causes a very acute onset in a short period of time caused by environmental factors and its own state; Chronic diseases are the consequences of organic lesions, and chronic diseases are irreversible because organic lesions are irreversible, so the purpose is to maintain.

Acute diseases can**, chronic diseases cannot**; Acute illness may become chronic if not timely**.

The most common cause of subacute necrotizing myelitis is intradural arteriovenous malformation, and there are four main types of spinal arteriovenous malformations

1.Dural arteriovenous fistula: mainly located in the lower thoracic segment and dorsal aspect of the conus** blood vessels originate from an artery and drain directly to the arterial vein. The typical age of onset is 50 to 80 years old, and about 60% of males are spontaneous and 40% are caused by trauma.

2.Angiobulbar malformation: located in the medulla, consisting of a mass of vascular plexus**Blood vessels come from multiple anterior and posterior spinal arteries, mostly dorsal to the cervical cord. The age of onset is milder and the onset of symptoms is more acute.

3.Juvenile arteriovenous malformations: large and complex vascular masses that can involve both intramedullary and extramedullary vessels,** involving multiple vertebral planes.

4.Intradural extramedullary arteriovenous fistula: **The blood vessels originate from the anterior spinal artery and are completely located outside the medulla. The age of onset is between 30 and 60 years. Clinical symptoms develop gradually.

Subacute necrotizing myelitis - pathogenesis.

The symptoms of subacute necrotizing myelitis are mainly caused by spinal cord blood supply disorder and spinal cord tissue ischemic infarction, and the possible mechanisms include venous drainage disorder, venous blood theft, compression of vascular masses, and embolization of abnormal blood vessels.

Pathologic changes: the dorsal surface of the spinal cord is covered with flexion and circumflex vessels on visual examination. Spinal cord is locally thinner, cystic, and discolored.

Microscopic examination shows myelination and spinal cord necrosis along the intradural spinal nerve roots, in addition to significant thickening of the subarachnoid vessel wall. This presentation may be focal or transverse. There is also obvious angiogenesis within and outside the necrotic lesions.

The onset is slower than the acute, the disease is faster than the chronic, and the course is between the two, and the course of the disease is also in between The disease does not have a uniform time for subacute, but each disease has its own acute, subacute, and chronic divisions.

Acute illness is to the degree of **, requiring 1 or more times; Chronic diseases are generally treated with 1015 sessions as a course of treatment, with a few days to weeks of rest during the treatment period.

Chronic disease is a disease that is gradual in nature and has less intense symptoms.

Chronic diseases are caused by degenerative changes in certain tissues and organs, or infection with viruses. Chronic diseases can reduce people's ability to work and lose their interest in life.

Chronic illness is afraid of other acute illnesses at the same time, intolerance of surgical injuries or drug reactions in acute illness**. More than half of the people in China suffer from various types of chronic diseases, such as hypertension, frequent outbreaks, neurasthenia, arthritis, bronchitis, asthma, habitual constipation, low white blood cells or platelets, chronic gastritis, obesity, hyperlipidemia, high blood viscosity, arteriosclerosis, coronary heart disease, chronic hepatitis, cholecystitis, etc., these chronic diseases seriously endanger human health.
