The health of hairy children needs careful care from you and me! When a hairy child is sick, it is difficult to clearly express what is wrong with his body because he can't talk. If he meets his careless master again, it is often too late to save his health after discovering the disease.

Unfortunately, many chronic diseases have no obvious symptoms and are easily overlooked by us, among which tumors are quite classic examples.

For example, if you find that a dog's feet become swollen, hard and warm, and there are symptoms such as limping and unwilling to walk, you must be alert: the dog may have a tumor!

If you find that your dog's feet are swollen and you don't like to walk, you need to be vigilant! Oh, no, did I touch a tumor? It must be noted that the dog's paw edema is not the tumor itself, but the paw edema comes from paraneoplastic syndrome (PNS) caused by tumor in vivo.

Tumors always make people turn pale at the smell. However, in addition to the health crisis caused by the tumor itself, the "products" of the tumor will indirectly cause systemic effects, causing the so-called paraneoplastic syndrome, which is even more likely to lead to animal death than the tumor itself. The only advantage is that not all tumors will have paraneoplastic syndrome.

Why is there paraneoplastic syndrome?

Generally speaking, tumors have different basic functions according to different cell sources. Adenocarcinoma, for example, comes from glands and has a strong secretory function.

However, tumors also secrete substances that are not derived from cells, such as hormones or cytokines, which cause problems in the morphology and function of distant tissues and organs, or cause endocrine disorders and abnormal immune response, thus affecting nerves, digestive tract, hematopoiesis, bones and joints, kidneys, skin and other parts and causing a series of symptoms, which we call syndrome.

Tumors have different functions according to different source cells. Wikimedia mon, magnificently, paraneoplastic syndrome may include cachexia, malignant hypercalcemia, hypoglycemia, anemia and disseminated intravascular coagulation [2]. And what this paper pays special attention to is hypertrophic pulmonary osteopathy.

What is the symptom of hypertrophic pulmonary osteopathy, which makes the soles of the feet swell?

As mentioned above, due to the obvious diffuse periosteal reaction between metacarpal and metatarsal, the new bone will * * * soft tissue, which will make the dog feel pain, so it will limp or be unwilling to move.

X-ray images of dogs with hypertrophic pulmonary osteopathy? (Headley et al., 2005), there were bilateral diffuse irregular fence-like periosteal reactions in metacarpal bone. Furthermore, due to the hypertrophy of bones, limbs will feel solid, warm and even bigger, and they will feel swollen and hard when touching them.

As for dogs with general primary lung tumor, dry cough lasts for several months because the lump in the lung can cause foreign body sensation, and at the same time, due to the decrease of gas exchange function, it can be manifested as shortness of breath or exercise intolerance.

Finally, of course, there are many nonspecific symptoms of chronic diseases, such as mental illness, loss of appetite, weight loss and so on.

Usually, the more names of diseases, the less we know about them, and hypertrophic pulmonary osteopathy is no exception.

Hypertrophic pulmonary osteopathy not only has a name, but also can be called hypertrophic osteopathy or secondary osteopathy.

In the same way, although we know that hypertrophic pulmonary osteopathy is one of paraneoplastic syndromes, the exact pathogenesis of hypertrophic pulmonary osteopathy is still unclear. Only * * nerves increase the blood flow of limbs, promote periosteal reaction, and then constantly generate new bones, which eventually leads to bone hypertrophy and other theoretical hypotheses.

Watch out! The focus is still on the lungs! Since it is called hypertrophic "lung" osteopathy, what is its relationship with "lung"? In fact, hypertrophic pulmonary osteopathy is mostly caused by "lung tumor".

In dogs, whether the tumor first occurs in the lung (primary lung tumor) or the tumor metastasizes from bone to lung (primary bone tumor but lung metastasis), a mass usually appears in the chest cavity, which may lead to 1 hypertrophic pulmonary osteopathy.

Therefore, if we want to treat hypertrophic pulmonary osteopathy, amputation alone can't solve the problem at all, that is to say, we must find out the primary position of the tumor in order to cut off the cause of the disease from the source.

If we can correctly diagnose and remove lung tumors, the pain on bones can usually subside within a few months, and with the help of analgesia, we can get a better quality of life.

If it is a primary "lung" tumor, but amputation, it will not solve the problem at all. However, Marty Miroshnichenko must pay attention that even if it subsides, it does not mean that it is cured, because once a dog has hypertrophic pulmonary osteopathy, it usually means that lung metastasis has occurred and the tumor has metastasized, which basically means that the tumor is on the verge of losing control.

Medical+personal = not necessarily! The above contents are "common situations", however, there are exceptions if there are laws. Medicine is usually not 100%, but has a series of uncertainties.

Although most hypertrophic pulmonary osteopathy is related to the lung, besides lung tumors, tumors such as kidney, adrenal gland and bladder, and even systemic infection may also cause hypertrophic pulmonary osteopathy [5]. In addition, bone hypertrophy may not appear in limbs, but in long bones, such as radius and ulna, which is equivalent to forearm.

Generally speaking, dogs with primary lung tumor may have a dry cough lasting for several months due to foreign body sensation, and may show shortness of breath or exercise intolerance due to the decline of gas exchange function, and may also have symptoms such as nonspecific spirit, loss of appetite and weight loss.

Since the cause of hypertrophic pulmonary osteopathy is lung tumor, it is reasonable to say that respiratory symptoms should also occur.

In fact, however, dogs with hypertrophic pulmonary osteopathy may not necessarily have respiratory symptoms, and some documents even point out that 30% of dogs have no symptoms at diagnosis [2].

Therefore, seeing you here, besides knowing how to take care of the health of hairy children and learning to pay attention to whether the soles of your feet are hypertrophy, don't take the pathogenic mechanism of the article as a Bible. When you find that the soles of your feet are swollen, it will be a bolt from the blue, and the dog will feel at ease without coughing.

Early detection and early treatment, master! Depend on you! There are more and more people keeping pets in Taiwan Province Province, China. According to the statistics of Animal Protection Department of Agriculture Committee of Executive Yuan 18, there are 530,000 domestic dogs/KLOC-0 and 760,000 domestic cats in China.

With the enhancement of owner's consciousness and the progress of veterinary specialty, the life span of children is gradually extended. However, with the increase of age, the decline of physical function and the probability of exposure to various risk factors are also increasing, and the possibility of cancer is also increasing.

With the enhancement of owner's consciousness and the progress of veterinary specialty, the life span of children is gradually extended. The highest guiding principle of Miroshnichenko tumor in horses is "early detection and early treatment". If you can receive proper treatment at an early stage, you will usually have a better response to treatment.

In addition to the basic regular health check-up, you can also feel your baby at any time to see if there are any unknown lumps, long-term unhealed wounds, unexplained weight loss, or various unexplained bleeding, such as hematuria or nosebleeds.

Of course, having these symptoms does not necessarily mean that it is a tumor, but the owner should be alert to the abnormality, and take it to the veterinarian for further examination, get a correct diagnosis, and discuss the appropriate treatment, so that the hairy child can live a healthy and happy life for a long time.
