Venereology is a branch of medicine that is concerned with the study and treatment of sexually transmitted diseases (STDs). The name derives from Roman goddess Venus, associated with love, beauty and fertility. A physician specializing in venereology is called a venereologist. [1] In many areas of the world, the specialty is usually combined with dermatology. [2]
The venereal diseases include bacterial, viral, fungal, and parasitic infections. [3] Some of the important diseases are HIV infection, syphilis, gonorrhea, candidiasis, herpes simplex, human papillomavirus infection, and genital scabies. Other sexually transmitted infections studied in the field include chancroid, lymphogranuloma venereum, granuloma inguinale, hepatitis B, and cytomegalovirus infection. [4]
In India, formal training of venereologists started in 1910, prompting microscopy and serology to come into general use throughout the Empire. Before this, many cases of early syphilis were either diagnosed as chancroid or missed altogether. To come to a diagnosis, doubtful atypical cases were at times left untreated to see whether they developed secondary syphilis. [5]
In the early part of the twentieth century, the medical science of venereology encompassed only the five classical venereal diseases: gonorrhea, syphilis, chancroid, lymphogranuloma venereum, and granuloma inguinale (donovanosis). [6] [7] The history of virology shows that, in the first decade of the 20th century, viruses were not well understood.
In the early 1960s there were approximately six STDs described in textbooks and very little research was happening in sexually transmitted infections. In fact, there were not many medical centers where clinical care was offered for patients with STDs, who were left with few resources. [8]
Safe sex is sexual activity using methods or contraceptive devices to reduce the risk of transmitting or acquiring sexually transmitted infections (STIs), especially HIV. "Safe sex" is also sometimes referred to as safer sex or protected sex to indicate that some safe sex practices do not eliminate STI risks. It is also sometimes used colloquially to describe methods aimed at preventing pregnancy that may or may not also lower STI risks.
Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The signs and symptoms of syphilis vary depending in which of the four stages it presents. The primary stage classically presents with a single chancre though there may be multiple sores. In secondary syphilis, a diffuse rash occurs, which frequently involves the palms of the hands and soles of the feet. There may also be sores in the mouth or vagina. In latent syphilis, which can last for years, there are few or no symptoms. In tertiary syphilis, there are gummas, neurological problems, or heart symptoms. Syphilis has been known as "the great imitator" as it may cause symptoms similar to many other diseases.
Neisseria gonorrhoeae, also known as gonococcus (singular), or gonococci (plural), is a species of Gram-negative diplococci bacteria isolated by Albert Neisser in 1879. It causes the sexually transmitted genitourinary infection gonorrhea as well as other forms of gonococcal disease including disseminated gonococcemia, septic arthritis, and gonococcal ophthalmia neonatorum.
Lymphogranuloma venereum is a sexually transmitted infection caused by the invasive serovars L1, L2, L2a, L2b, or L3 of Chlamydia trachomatis.
Chancroid is a bacterial sexually transmitted infection characterized by painful sores on the genitalia. Chancroid is known to spread from one individual to another solely through sexual contact. However, there have been reports of accidental infection through the hand.
Granuloma inguinale is a bacterial disease caused by Klebsiella granulomatis characterized by genital ulcers. It is endemic in many less-developed regions. It is also known as donovanosis, granuloma genitoinguinale, granuloma inguinale tropicum, granuloma venereum, granuloma venereum genitoinguinale, lupoid form of groin ulceration, serpiginous ulceration of the groin, ulcerating granuloma of the pudendum, and ulcerating sclerosing granuloma. Oral manifestations are also notably seen. The lesions of oral cavity are usually secondary to active genital lesions.
Albert Ludwig Sigesmund Neisser was a German physician who discovered the causative agent (pathogen) of gonorrhea, a strain of bacteria that was named in his honour.
Proctitis is an inflammation of the anus and the lining of the rectum, affecting only the last 6 inches of the rectum.
Sexual health clinics specialize in the prevention and treatment of sexually transmitted infections.
A genital ulcer is an open sore located on the genital area, which includes the vulva, penis, perianal region, or anus. Genital ulcers are most commonly caused by infectious agents. However, this is not always the case, as a genital ulcer may have noninfectious causes as well.
Condom effectiveness is how effective condoms are at preventing STDs and pregnancy. Correctly using male condoms and other barriers like female condoms and dental dams, every time, can reduce the risk of sexually transmitted infections (STIs), including human immunodeficiency virus (HIV) and viral hepatitis. They can also provide protection against other diseases that may be transmitted through sex like Zika and Ebola. Using male or female condoms correctly, every time, can also help prevent pregnancy.
Gonorrhoea or gonorrhea, colloquially known as the clap, is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. Infection may involve the genitals, mouth, or rectum. Infected men may experience pain or burning with urination, discharge from the penis, or testicular pain. Infected women may experience burning with urination, vaginal discharge, vaginal bleeding between periods, or pelvic pain. Complications in women include pelvic inflammatory disease and in men include inflammation of the epididymis. Many of those infected, however, have no symptoms. If untreated, gonorrhea can spread to joints or heart valves.
A sexually transmitted infection (STI), also referred to as a sexually transmitted disease (STD) and the older term venereal disease (VD), is an infection that is spread by sexual activity, especially vaginal intercourse, anal sex, oral sex, or sometimes manual sex. STIs often do not initially cause symptoms, which results in a risk of passing the infection on to others. Symptoms and signs of STIs may include vaginal discharge, penile discharge, ulcers on or around the genitals, and pelvic pain. Some STIs can cause infertility.
Ivan Ivanovich Mavrov was a Ukrainian physician.
Patient-delivered (partner) therapy, is the practice of treating the sex partners of people diagnosed with chlamydia or gonorrhea by providing prescriptions or medications to the person to take to their partner without the health care provider first examining the partner. EPT may also include other forms of implementation than PDPT.
The Guatemala syphilis experiments were United States-led human experiments conducted in Guatemala from 1946 to 1948. The experiments were led by physician John Charles Cutler, who also participated in the late stages of the Tuskegee syphilis experiment. Doctors infected 1,300 people, including at least 600 soldiers and people from various impoverished groups with syphilis, gonorrhea, and chancroid, without the informed consent of the subjects. Only 700 of them received treatment. In total, 5,500 people were involved in all research experiments, of whom 83 died by the end of 1953, though it is unknown whether or not the inoculations were responsible for all these deaths. Serology studies continued through 1953 involving the same vulnerable populations in addition to children from state-run schools, an orphanage, and rural towns, though the intentional infection of patients ended with the original study.
Syphilis is a bacterial infection transmitted by sexual contact and is believed to have infected 12 million people in 1999 with greater than 90% of cases in the developing world. It affects between 700,000 and 1.6 million pregnancies a year, resulting in spontaneous abortions, stillbirths, and congenital syphilis. In Sub-Saharan Africa syphilis contributes to approximately 20% of perinatal deaths.
The outbreaks of sexually transmitted diseases in World War II brought interest in sex education to the public and the government. During the late 1930s and early 1940s, military maneuvers increased worldwide and sexual hygiene and conduct became major problems for the troops. Soldiers and sailors on assignment overseas were often lonely, had time to spare, got homesick, or were just looking for female companionship. This resulted in many men having multiple sex partners, and as a result, became a major health concern. During the Great War, venereal diseases (V.D.) had caused the United States Army to lose 18,000 servicemen per day. Although by 1944 this number had been reduced 30-fold, there were still around 606 servicemen incapacitated daily. This drop in numbers was partly because of the Army's effort to raise awareness about the dangers faced by servicemen through poor sexual hygiene, and also because of the important developments in medicine. In late 1943 a case of gonorrhea required a hospital treatment of 30 days, and curing syphilis remained a 6-month ordeal. By mid-1944, the average case of gonorrhea was reduced to 5 days, and in many cases the patient remained on duty while being treated.
John Friend Mahoney was an American physician best known as a pioneer in the treatment of syphilis with penicillin. He won the 1946 Lasker Award.
John Arthur Harland Hancock was a British venereologist and editor of the British Journal of Venereal Diseases who wrote on non-gonococcal urethritis and reactive arthritis, what was known as Reiter's disease at the time. In 1945, while studying medicine at the London Hospital, he was one of the voluntary students sent to Belsen to assist nutritionist Arnold Peter Meiklejohn in feeding the starving inmates. There, he became unwell with typhus and was treated back at The London by Lord Evans.
