Symptoma

Sexually Transmitted Disease

STD

Sexually transmitted diseases (STDs) are generally acquired by sexual contact.

Some common presentations include:

  • Urogenital

Presentation can be simply that the genitals are red and sore to sometimes painful and swollen. There may be a burning sensation in urinating and a white or coloured discharge may be found from the vagina or penis. There may be sores, ulcers, blisters or warts.

  • Systemic

If the infection has spread, there may be systemic effects [3]. The infective agent may affect the heart, kidneys, brain, eyes, joints, etc.

  • Lymphadenopathy

    Three were diagnosed in 2009 in HIV-negative heterosexuals patients that presented the classical genito-ulcerative form with lymphadenopathy. [ncbi.nlm.nih.gov]

    Inguinal lymphadenopathy is present in about 50% of the patients with genital ulcer diseases. Genital herpes typically presents with multiple, shallow ulcers and bilateral lymphadenopathy. [web.archive.org]

    Regional lymphadenopathy adjacent to the chancre may develop during primary syphilis. The swollen lymph nodes are firm, nonsuppurative. Lymphadenopathy may persist for months, despite healing of the chancre. [atsu.edu]

    Primary genital HSV infection can range from asymptomatic infection to a severe syndrome with multiple painful genital ulcers, fevers, dysuria, and tender lymphadenopathy. [clinicaladvisor.com]

    Look for lumps, swelling, lymphadenopathy, abnormal discharge, sores, ulcers, tears and scars around the genitals and in between the skin folds of the vulva. Speculum examination for: Vaginal discharge and redness of the vaginal walls (vaginitis). [patient.info]

  • Unsafe Sexual Practices

    Sexually Transmitted Diseases Sexually transmitted diseases (STDs) are a real and unfortunate result of unsafe sexual practices. They can be transmitted through oral, vaginal, or anal intercourse. [med.nyu.edu]

    The frequency of unsafe sexual practices and the reported rates of bacterial STDs and incident HIV infection declined substantially in MSM from the 1980s through the mid-1990s. [cdc.gov]

  • Hoarseness

    These growths can sometimes block the airway, causing a hoarse voice or trouble breathing. How does HPV lead to health problems? In most cases the virus goes away and it does not lead to any health problems. [web.archive.org]

  • Notched Incisors

    During the second dentition, the three signs, as pointed out by Jonathan Hutchinson, may be looked for â ” the notched incisor teeth of the upper jaw, interstitial corneitis and syphilitic deafness. [en.wikisource.org]

  • Metallic Taste

    If given, however, in doses larger than can be borne by the patient, its poisonous effects are manifested by a metallic taste, by watering of the eyes and by the breaking out on the back and shoulders of scattered pimples. â ! [en.wikisource.org]

  • Ecthyma

    In this patient’s case, the bacteria caused the formation of a skin infection known as a pyoderma, or ecthyma. CDC Figure 38 This colposcopic view of this patient’s cervix reveled an eroded ostium due to Neisseria gonorrhea infection. [web.archive.org]

  • Radiculopathy

    Extragenital manifestations of HSV include ulcerative lesions of the buttock, groin, thighs, pharyngitis, aseptic meningitis, transverse myelitis and sacral radiculopathy. [web.archive.org]

  • Cranial Neuropathy

    These involve dermatologic (figure 12-13), central nervous system (aseptic meningitis, cranial neuropathy), ocular (iritis, uveitis or conjunctivitis), hepatic (hepatitis) and renal (immune complex glomerulonephritis) systems. [web.archive.org]

  • Vaginal Discharge

    Considering more than 20 studies of lower tract inflammation, M. genitalium has been positively associated with urethritis, vaginal discharge, and microscopic signs of cervicitis and/or mucopurulent cervical discharge in seven of 14 studies. [ncbi.nlm.nih.gov]

    and vaginal discharge. [dx.doi.org]

  • Salpingitis

    PID can manifest as endometritis, salpingitis, adnexitis, tubo-ovarian abscess, pelvic peritonitis (figure 46) or perihepatitis. The most common manifestation of PID is salpingitis, and these terms are used synonymously in the literature. [web.archive.org]

    However, the disease can also spread to the Fallopian tubes and other internal genital organs, causing such conditions as salpingitis pelvic inflammatory disease tubal blockage (this can lead to infertility). [netdoctor.co.uk]

    Experimental animal models have also provided evidence that M. genitalium can colonize upper reproductive tract tissues, leading to salpingitis or endometritis [61] – [63]. [dx.doi.org]

  • Chronic Pelvic Pain

    In women, chlamydia can cause pelvic inflammatory disease (PID), which can result in infertility, chronic pelvic pain, or tubal pregnancies. In men, it can cause urethral infection or swollen testicles. [acphd.org]

    It must be treated with antibiotics, otherwise it can spread to other pelvic organs and lead to chronic pelvic pain and infertility. Your sexual partner will need to be treated also. [ucsfhealth.org]

    Among the most serious STD complications are pelvic inflammatory disease, ectopic pregnancy (pregnancy outside of the uterus), infertility, and chronic pelvic pain.7 Age disparities. [healthypeople.gov]

  • Dysuria

    Primary genital HSV infection can range from asymptomatic infection to a severe syndrome with multiple painful genital ulcers, fevers, dysuria, and tender lymphadenopathy. [clinicaladvisor.com]

    Vaginitis presents with an increase in the amount, odor or color of discharge and may be accompanied by itching, dysuria, dyspareunia, edema or irritation of the vulva. [web.archive.org]

    Symptoms, if present, include dysuria; urethral pruritis; and mucoid, mucopurulent, or purulent discharge. Signs of urethral discharge on examination can also be present in persons without symptoms. [cdc.gov]

    Men infected with M. genitalium frequently present with dysuria, while women may present with or without urogenital symptoms. [doi.org]

    Initial manifestations include local pain, tenderness, itching sensation, and dysuria. The pain associated with dysuria in females is described as more of an “external pain”. [atsu.edu]

The work up includes blood sampling for culture and sensitivity. A swab sample of fluids may be collected from the throat, cervix, vaginal canal and/or rectum in females and throat, penile urethra and/or rectum in males.

Laboratory Tests Results

  • Gram staining: Gram staining may be done to check for the organism involved.
  • PCR: A Polymerase Chain Reaction test maybe done for more accurate results.
  • C/S: Culture and sensitivity of either blood samples, urine or swab samples may be done for accurate results.

If the test results come positive for one STD, treatment is immediately started. Other STDs are also checked.

  • Multiple Ulcerations

    A 41 year-old, sexually promiscuous, married male, an agricultural laborer by occupation, presented to our sexually transmitted diseases (STD) clinic with multiple ulcers over the scrotum and genitalia of 20 days' duration. [ncbi.nlm.nih.gov]

The exact treatment varies depending upon the type of STD it is. But generally, treatment is either oral or parenterally administered antibiotics. The common regime used these days for gonorrhea and chlamydia infection is Ceftriaxone, Azithromycin and Doxycycline given in a combination to prevent reoccurrence.

STDs, if treated adequately, have a good prognosis, unless it's an incurable one like AIDS. Symptoms are mild at first and if the diagnosis is made on time, and appropriate antibiotics are administered, symptoms regress completely.

However, if for example primary syphilis is left untreated and it progresses to tertiary syphilis, it may cause irreversible damage.

Complications

If left untreated, an STD may lead to:

Males

Females

A sexually transmitted disease is caused by microorganisms which are transferred from an infected individual to his/her sexual partner during intercourse.

Mode of Transmission:

  • Sexual Transmission

This is the most common mode of transmission. An individual may knowingly or unknowingly transmit the pathogen to his or her sexual partner by either oral, vaginal or anal sex. Depending upon the kind of intercourse performed, the microbes may start an infection in that area. For example, anal sex leads to development of disease primarily in the rectum, oral sex leads to infection in the throat, etc. [10].

  • Intravenous Drug Abuse

Drug addicts often share needles and syringes with each other and this unsanitary and unchecked misuse is also a leading cause of transferring infections. Of such, HIV is a very commonly transferred disease.

  • Mother to child

Some STDs can be transferred from an infected mother to her child during childbirth when the baby passes through the infected birth canal. STDs like Gonorrhea can be transferred from mother to child during cord clamping as a fluid exchange may occur.

  • Other

Other causes include exposure to a pathogen on an open wound, administration of donor blood that is contaminated with a microbe, etc.

Incidence

Studies conducted by the Centres of Disease Control reveal that there are 19.7 million new cases of sexually transmitted diseases occurring in the United States annually [1]. It is estimated that one in every 4 teenagers contracts an STI and/or STD each year.

Sex

Most STDs, though not all, are more common in women than in men. The exact prevalence varies with different types of STDs. Female to male ratios of some common STDs are mentioned below:

  • Chlamydia infection occurs in 592.2 per 100,000 people in females as compared to just 219.3 per 100,000 people in males. 
  • Gonorrhea occurs in 105.5 per 100,000 people in females as compared to just 91.9 per 100,000 people in males. 
  • But in the case of Syphilis, the rate among men is much higher. The ratio being almost 1:7 in the US in 2009.

Age

STDs can occur at any age, ranging from in babies (in the case of gonorrhea which can be contracted by an infant during birth from an infected mother) to old age. But it is most commonly found in young people between 15-24 years of age.

Race

Most STDs are more prevalent in people belonging to the African-American race than in white people.

Most Prevalent STDs

  • The most common STD in the world is Chlamydia infection.
  • The second most common STD in the world is Gonorrhea.

When an affected individual has unprotected sexual intercourse with his/her sexual partner, the bacteria or other microbes enter into the genital tract. The primary area of infection depends upon the type of intercourse performed, for example, vaginal intercourse may cause the primary area of infection to be the vagina and cervix, anal intercourse leads to a primary infection in the rectum, oral sex leads to a throat infection, etc. [9].

Once a primary infection has been established, symptoms may or may not appear. The microbes may move from the genital tract to the lymphatic system and then enter the blood stream. If that happens, systemic effects appear [7].

Common STDs and Causative Agents:

Bacterial

Viral

Protozoal

Fungal

Common Symptoms:

STDs can be easily prevented. Preventive measures include:

  • Using latex condoms during intercourse [5]
  • Getting checked for STDs, at least once a year if sexually active
  • Having only one sexual partner
  • No drug abuse
  • Using syringes, donated blood, etc from reliable and well sanitised centres

Sexually transmitted diseases (STD) are a leading cause of hospital check ups in the world. Studied under a separate branch of science called Venereology, sexually transmitted diseases can be caused by a number of pathogens resulting in an extensive range of diseases.

It should be noted that the term STD should not be confused with STI (sexually transmitted infection). An STI indicates that a person is infected with a certain pathogen, but he is asymptomatic and that infection has not progressed to a disease yet [2]. An STD however, denotes that the infection is not latent anymore but has progressed to the disease. So it should be clear that the term STI has a broader range as it covers everyone with an infection by a known venereal disease causing pathogen and that person, symptomatic or not, has the potential to infect others as well.

Although very diverse on the basis of causative agents and signs, STDs may have a number of things in common. Some of these symptoms include: red, swollen and painful genitals, discharge from penis or vagina, ulcers or warts, burning micturition [8], etc.

Definition

A sexually transmitted disease is a bacterial, viral or fungal infection that infects the genital tract.

Cause

The microbes may enter the body through unprotected vaginal, anal or oral sex, or from contaminated needles and blood [6].

Signs and Symptoms

Common signs and symptoms include red swollen genitals, discharge from the penis or vagina, a feeling of burning pain during urination, warts, ulcers, etc.

Treatment

Treatment is usually of an antibiotics course.

Prevention

STDs can be very easily avoided if proper precautionary measures are taken. These include use of latex condoms during sex, regular testing for STDs if multiple sexual partners, spreading awareness among youngsters, etc.
