A 5-year-old girl has yellow secretions on her pants, causing parents to worry about "precocious puberty"; Due to a swim during the holiday, a 7-year-old girl always feels itchy in her lower body; The girl had her first menstrual period at the age of 9, while the girl who was in her third year of junior high had amenorrhea due to academic pressure; A 12 year old girl was diagnosed with uterine malignancy due to irregular vaginal bleeding... These are all cases encountered at the Youth Gynecology Clinic of Xinhua Hospital affiliated with Shanghai Jiao Tong University Medical College (hereinafter referred to as "Xinhua Hospital"), which are closely related to the girl's growth and development as well as her future fertility. The Youth Gynecology Clinic of Xinhua Hospital is the first youth gynecology clinic in Shanghai, which has been open since 2020. In the past three years, the number of patients seeking medical treatment has gradually increased, from the original single digit to over 40 patients in half a day. Weekends and winter and summer are peak periods, and doctors often have extra appointments to see patients. As the leader of the hospital's gynecology department, Wang Xipeng formed a team consisting of gynecological and reproductive doctors to provide this outpatient service. Teenage gynecological clinics have established precedents in China, but in recent years, in addition to focusing on common gynecological diseases, fertility preservation for adolescent cancer patients has also become a major focus of attention. In clinical practice, gynecology is often classified as an adult rather than a pediatric field, but many gynecological diseases originate from adolescence, such as reproductive system tumors. We hope to discover the causes or high-risk factors behind adolescent gynecological diseases in a timely manner, reducing the possibility of more serious gynecological diseases in the future. "Wang Xipeng said, considering the particularity of the affected population, Xinhua Hospital has also collaborated with Shanghai Pediatric Specialized Hospital for this purpose, This outpatient clinic has been simultaneously opened at the Shanghai Children's Medical Center. What adolescent development problems require medical attention? In the just past summer, we have experienced a peak of medical treatment, "Wang Yizhi, a gynecologist at Shanghai Xinhua Hospital, told Pengpai News on September 12th. Most of the students who came to see us were from the lower grades of kindergarten to primary school, especially first grade students. Many of them had symptoms of excessive secretion and itching of the external genitalia, and were diagnosed with vaginitis, vulvitis, and other conditions. The reason for this is that many students have had experiences of playing in swimming pools, water parks, and other places. Vaginitis is the most common disease in adolescent gynecological clinics, and parents often feel nervous. "Wang Yizhi explained that due to the different pH values of swimming pool water and female vaginal environment, it is easy for children with low immunity to experience corresponding symptoms, such as increased secretion, itching of the lower body, and urgency to urinate. Parents are often concerned about their children's adolescent development issues, and there is also a type of outpatient demand related to abnormal physiological changes during menstruation, such as dysmenorrhea, irregular menstruation, and early menarche. A 15-year-old girl named Momo (pseudonym) came to seek medical attention due to dysmenorrhea. Her mother hesitated about whether to take painkillers or not, worried about their impact on the child's nerves, whether painkillers would become addictive, and whether they would have side effects that would affect learning. The statement provided by Wang Yizhi is: "It is still necessary to eat. Alleviating pain is necessary for children's lives and studies, but it is necessary to use medication scientifically under the guidance of a doctor and not on their own
