The day before yesterday, there was a patient in the outpatient clinic, it was Lao Zheng from Hui'an, Quanzhou, Lao Zheng sat down and asked: "Doctor, do you see that my left hand has eczema, there is eczema ointment, it has been a few days, it is not good, my son said that your ** hospital has homemade eczema cream (chlorine cream), I want to try it." I looked at it, and it looked a bit like eczema to the naked eye, but it was a little strange, and I couldn't say ** strange, so I asked "Did you get stung by something", "It doesn't seem to be." Oh yes, there was one the other day. It turns out that Lao Zheng has been doing fishing work all his life, and a few days ago he returned to his hometown because of his relatives' marriage, helping this, helping that, and helping to kill fish, and it was quite easy to do, but he was stabbed by a fish bone during the period, thinking that he had been fishing all his life, and he often had a small injury, and he didn't care, but he didn't expect that this stab would cause such a serious reaction. "You have granulomas in swimming pools, it is best to do a pathological biopsy, ** combined with oral anti-inflammatory drugs, and you have to take it for a period of time", so he gave him a prescription of "clindamycin + byfolle + rifampicin".
So what is swimming pool granuloma?
Swimming pool granuloma, also known as diver's disease or fish tank granuloma, is an infection caused mainly by mycobacterium marinum. This bacterium is commonly found in fresh water and seawater, and can infect the human body through broken **, so swimming pool granulomas through swimming is only one of the ways of infection, and being stung by fish bones, scratched by shells, etc. are all ways of infection. What are the characteristics of granuloma in swimming pools, and how to prevent it?
Clinical symptoms. Symptoms usually begin to appear within two to three weeks of infection, and may initially appear as an inflammatory reaction such as redness, swelling, and pain. Later, purplish-red or brown bumps may form, which may be accompanied by ulcers or oozing and may persist for a long time without healing. Granuloma occurs mainly in the hands or arms, but it can also spread to deeper tissues, such as tendon sheaths and joints.
Symptoms of swimming pool granuloma may include:
Red. Ulcers that do not heal for a long time.
Pain. Lump formation.
Granulomatos or nodules.
Pathologic features. Diagnosis of swimming pool granulomas usually requires a pathological biopsy with the following pathological features:
Histopathological manifestations: pathological tissue examination can find granulomas, with a large number of lymphocytes and macrophages infiltrated, some may present granulomas similar to tuberculous, and juvenile and necrosis can be seen in the center. Infected areas tend to have a prominent peripheral inflammatory response, containing a large number of lymphocytes, plasma cells, and nuclear macrocytes.
Special staining and culture: Atypical mycobacteria cannot be developed with conventional HE staining and require acid-fast staining. Acid-fast staining was positive. Culturing atypical mycobacteria requires special media and conditions that are often not found in conventional bacterial cultures.
Immunopathological examination: immunoglobulin A (IgA) and complement C3 are deposited around the capillaries.
*。*Methods include antibiotics and topical medications, and severe cases may require surgical removal of infected tissue.
Prophylaxis. Prevention: Avoid exposing injured people** to water sources where mycobacteria can grow, such as swimming pools and aquariums. For people who are in frequent contact with water, such as swimmers and divers, you can wear protective gear to protect yourself from infection.
Education and awareness: Be aware of the symptoms of granuloma in swimming pools so that you can seek medical attention if symptoms appear. Share this information with people who work in the water to raise public awareness of the disease.
Swimming pools, aquariums and other related places should strengthen the monitoring and management of water quality to reduce the chance of the presence of mycobacteria and reduce the incidence of granulomas in swimming pools.
If you find out that you have swimming pool granulomas, follow your doctor's advice** and avoid buying medications on your own**. Adhere to the use of antibiotics and other medications for better infection control. In conclusion, understanding, prevention, and proper understanding of swimming pool granulomas are key to reducing the risk of infection and improving patient outcomes. If necessary, please consult a regular hospital** department to understand any concerns and questions about this condition. Learn a little about health every day
