Ms. Wu, 22, is a nail art enthusiast who goes to a nail salon to change her nails every two or three days.
Recently, she found small transparent lumps growing between her fingers. They were not painful or itchy, but they kept growing bigger, so she went to the dermatology department of the hospital for treatment.
After careful examination by the hospital's dermatologist, it was diagnosed that the growth between Ms. Wu's fingers was caused byHPVPeriungual warts caused by viral infection require liquid nitrogen cryotherapy.
According to the doctor, periungual warts are a type of common warts on the hands and feet, which are caused by human papillomavirus (HPV).InfectCaused by the formation of rough papules around the nails, between the toes and even under the nail skin.NodulesAlthough manicure is beautiful, it usually requires filing, polishing and trimming the cuticle. The cuticle protects the nail and the skin, and has a protective effect on the nail.
The dermabrasion process during manicure can easily cause tiny damage to the skin, allowing the HPV virus to "take advantage of the opportunity" to enter the epithelial cells and replicate and proliferate, causing abnormal differentiation and proliferation of epithelial cells, which may eventually cause nail damage.。
Doctors remind that the quality of nail salons on the market varies greatly. Many nail salons find it difficult to change tools for each person and lack strict disinfection.
therefore,When choosing a nail salon, pay special attention to whether the nail products are regular products, and choose a nail salon with good hygiene conditions.. In order to avoid damaging the skin tissue around the nails due to hygiene problems or improper operation, causing diseases such as paronychia, onychomycosis, and nail abscess.
For people who already have skin diseases or are susceptible to eczema, dermatitis and other diseases, it is recommended that you avoid manicures and nail polish. If you experience adverse reactions such as redness, swelling, yellowing, and blistering after manicures, you should see a dermatologist as soon as possible.
High-risk vs low-risk
What is the difference?
Although almost allCervical cancerare all related to HPV infection.But it does not mean that you will get cervical cancer if you are infected with HPV virus。
More than 200 HPV subtypes have been discovered based on the different viral nucleotide sequences.Different subtypes of HPV have different pathogenicity and are divided into high-risk and low-risk types, of which low-risk types account for the majority of infections.。
It can cause genital warts, warts, etc. The scientific name of warts is "wart”, it is contagious。
Common warts, filiform warts, plantar warts, flat warts, etc. may all be traces of the presence of HPV.
There are more than a dozen high-risk HPV types that can cause vaginal and cervical epithelial lesions and cervical cancer.Malignant tumorsThe occurrence of。
70% of cervical cancers are caused by persistent infection with high-risk HPV types 16 and 18; people with long-term HPV infection, especially HPV 16, are also at high risk of oral cancer.
If HPV infection is detected during screening, there is no need to panic, because HPV infection is a necessary but not sufficient condition for the occurrence of cervical cancer.
As long as the immune function is normal, most people can eliminate the HPV virus in their bodies within 2 years without taking special measures, and blindly using so-called "negative conversion" products is not recommended.。
However, if precancerous lesions are detected, they should be treated as soon as possible to prevent them from progressing to cervical cancer.
There is a long process from HPV infection to cervical cancer: HPV infection → persistent high-risk HPV infection → cervical intraepithelial neoplasia → invasive cervical cancer, usually takes several years or even decades.
and,Most women are infected with HPV only onceFor example, a healthy woman, especially one in her 30s, has better immune function and a stronger ability to clear the virus. She has a strong ability to "self-clean" the HPV that suddenly appears in her body.
The more sexual partners you have, the more chances of being infected with different subtypes of HPV virus. When multiple types of HPV viruses are present at the same time, the "self-purification" ability is overloaded, and the risk of cervical cancer increases significantly.
When having sexual intercourse, be sure to use condoms throughout the process, which can provide a certain degree of isolation; clean the vulva every day, and if you have a sexual partner, you should ask your partner to clean the vulva before sexual intercourse.
There are three types of HPV vaccines:
Bivalent vaccineCan prevent high-risk HPV16 and 18;
Quadrivalent vaccineHPV6 and HPV11 subtypes have been added to the prevention category, and genital warts can also be prevented;
Nine-valent vaccineIt can prevent nine types of HPV: 6, 11, 16, 18, 31, 33, 45, 52, and 58.
At present, imported vaccines are suitable for people aged 9 to 45 years old. Among domestic vaccines, some are suitable for people aged 9 to 45 years old, and some are suitable for people aged 9 to 30 years old. You can make a choice after consultation.
At present, the vaccine supply is tight in some areas. Everyone should get vaccinated as soon as possible after getting the vaccine they can get. There is no need to blindly pursue the nine-valent vaccine.
actually,The bivalent vaccine is enough to prevent more than 70% of cervical cancermy country also has a domestically produced bivalent vaccine with a very high cost-effectiveness.
It is best for women (after starting sexual activity) to start screening for cervical cancer at the age of 21. For women aged 21 to 29, only cytology screening is required every 3 years and HPV testing is not required.
For people aged 30 to 65, it is recommended to undergo combined cytology and HPV screening every 5 years, or cytology screening every 3 years.
Women over 65 years old can stop cervical cancer screening if they have no history of cervical precancerous lesions in the past 25 years and have had sufficient negative screening in the previous 10 years (the last examination was within 5 years).
After being infected with HPV, the natural clearance rate within 1 year through one's own immunity is about 70%, and about 90% within 2 years. If it exceeds 2 years, the doctor will make specific diagnosis and treatment.
For high-grade precancerous lesions, active treatment is recommended and the appropriate treatment method should be selected based on the size of the lesions. Patients must receive standardized diagnosis and treatment in a regular hospital.
