As a result of the publicity about STDs and the role of the overwhelming STD advertisements, many people mistakenly believe that any discomfort or rash in the genital area is an STD. Therefore, when it comes to STDs, people tend to be afraid of talking about them, which is known as “STD phobia” in medical terms. I encountered this kind of situation in the hospital dermatological venereal disease department outpatient and consultation work is not uncommon. A woman, 30 years old, a teacher. After having an extramarital sexual intercourse with a boyfriend of this unit, she was remorseful and thought she had an STD. She has repeatedly asked for examination, and has done cervical secretion gonorrhea culture 5 times, syphilis serological examination 7 times, HIV antibody test 6 times, all the results are negative. Clinical examinations of dermatology and gynecology also did not reveal any abnormalities. The patient repeatedly complained of frequent paroxysmal itching and pain in the pubic area, sometimes with local numbness and twitching. She was in the terror of venereal disease all day long, anxious and anxious, looking up medical books everywhere, saying that she had syphilis and was in the advanced stage. Sometimes they even think they have infected their dogs and cats with STDs. She often has insomnia, dreams and heart palpitations. The small red dots on my body and the damage to my son’s face were also considered to be STDs, which made the whole family restless. I am very excited to talk about my condition. I am incoherent. The most important thing is that you have to be able to get a good idea of what you are doing. One morning, near the end of the day, a young man who had been wandering outside the clinic for a long time came in shyly, red-faced, and said to me that he had something to hide, well and said his illness. It turns out that the young man is a college student, three months ago ran away to meet a female Internet friend and have sex. Recently, because of the discomfort in the head of the glans, it is suspected of having a sexually transmitted disease. I gave him a physical examination, found that the foreskin is a little too long, and accumulated a lot of foreskin, and then for him to make routine urine tests and other related STD tests, are normal. I repeatedly explained to him that he did not have a “sexually transmitted disease”, but he was still half convinced. Shortly afterwards, he came to the hospital again and asked for treatment for his “STD”, and I examined him again and still didn’t find any “STD”. He still had doubts about my diagnosis, and was suspicious all day long, to the point where he couldn’t sleep at night, was restless, and was terrified. He was later circumcised and treated by a psychiatrist to “cure his heart” that it was not a venereal disease. A young woman because of finger injuries took two tablets of “cotrimoxazole”, the second big found erythema and itching in the vulva, and soon ulcerated, water. To a private clinic, informed that it is a serious “STD”. She was discouraged and broke up with her boyfriend with pain. After that, she was so pessimistic and anxious that she drank pesticide to commit suicide, but fortunately her family found her and rushed her to the hospital to save her from death. I examined her and found that the culprit of her illness was “cotrimoxazole”, which caused an allergic reaction after she took the drug, and “fixed drug rash”, which is not related to STDs. One day, a friend brought an acquaintance to see me. The company’s main business is to provide a wide range of products and services to the market. “He panicked about it. After I examined him, I told him that he was suffering from “pearly penile papillomatosis”, and he was half convinced. Later I showed him pictures of this disease, and he believed that it was a minor disease that had little effect on human health and did not require special treatment. The cases listed above are just one of the many kinds of STD phobias, and one part of these patients have a history of unclean sex. He [she] lack of medical understanding of STDs, or only half-understanding, so the slightest discomfort in the pubic area will produce the psychology of terror, wrongly believe that all have a history of unclean sexual intercourse will certainly get STDs, where the genital area discomfort or rash will be STDs, and that STDs are difficult to cure, so the future of pessimism and disappointment, and even the idea of life. The STD terror (fear) is a kind of mental disorder, a kind of mental pain that can not get rid of the consciousness. Patients mostly know little about STDs, are stubborn about what they are aware of, and do not believe in some laboratory results. They believe that they have a disease and actively and urgently demand medical treatment. Another manifestation of STD phobia is to make unfounded connections, linking certain symptoms and manifestations that are not related to STD with STD. And some normal phenomena or phenomena not noticed in the past are treated as the manifestation of STD. STD phobia is caused by two factors, internal and external. The combination of internal and external factors, often make the patient a huge pressure. 1, their own factors: different individuals have a large difference in the understanding of disease and health, patients with low or high level of knowledge, lack of general knowledge of health, half knowledge of STDs or hearsay, easy to produce blind terror, although repeated clinical and laboratory tests to exclude STDs, but still doubtful, restless; patients often have a certain level of knowledge before the disease. 2, social factors: social factors on the occurrence, development, treatment and prognosis of STD phobia have a particularly important impact. Prostitution, prostitution is prohibited by law in China, but the society does exist these undesirable phenomena, so once suffering from STDs, will be discriminated against and rejected by society and their families, resulting in difficulties in interpersonal and family relations, aggravating the psychological burden of patients; STD prevention and treatment knowledge education is not popular, coupled with the abnormal publicity caused by the bad influence of the deformity is also one of the factors causing STD phobia. . 3, medical factors: a few medical personnel with inappropriate language, expression, attitude and behavior overly exaggerate the seriousness of STDs, or attitude is not serious, do not respect the patient’s personality and privacy, seriously damage the patient’s self-esteem, aggravating its psychological burden. Even a few unscrupulous people, under the guise of practicing medicine, to earn money for the purpose of non-STD or cured STD patients to carry out unnecessary tests and other therapies, administering unnecessary and expensive drugs, further aggravating the psychological and economic burden of patients. The main treatment for STD phobia is patient guidance, explanation and reassurance, and listen carefully to the patient’s narrative, and let the patient tell all the feelings in his heart, which is also a psychological treatment. And do a good job of publicity, so that patients have a correct understanding of the knowledge of sexually transmitted diseases, put down the burden of “worrying about people”. Only with “heart disease to heart medicine cure” method can make this be “scared out” out of the “venereal disease” get cured. At the same time various advertisements should be standardized management: standardized propaganda advertising can bring useful information for people. However, some unscrupulous people carry out unrealistic and unserious advertising for their own personal benefit. The publicity materials which are hard to distinguish from the real ones sometimes become one of the root causes of fear and anxiety for the patients with STD phobia. The only way to reduce unnecessary pollution of the social environment is to standardize management and avoid exaggerating about STD diseases. At the same time, in scientific and popular language, patiently tell patients about sexually transmitted diseases, so that they can fully and correctly understand the knowledge about STDs and relieve all kinds of suspicions and worries, so as to reduce psychological pressure. The reason for this is the intimidation and lure of STD patients and the arbitrary price, thus generating many irregular private clinics and stirring up chaos in the STD treatment market. Therefore, it must be rectified and strictly managed in order to return the STD patients an orderly market for medical treatment.
