Sexually Transmitted Diseases (STD)


There are now more than twenty disorders recognized as being


transmitted primarily by sexual means. The more familiar STD’s are AIDS,


gonorhea, syphilis, chlamydia-related infections, genital herpes, candidiasis,


nonspecific vaginitis, trichomoniasis, pediculosis, scabies, and urinary tract


infections.


GONORRHEA


One of the most frequently encountered communicable diseases in


the U.S. It is caused by the bacterium Neisseria Gonorrihoeae, which is common


all over the world today and can only thrive in human beings. There is no way to


acquire immunity to this disease. Anyone who is sexually active is susceptible


to gonorrhea.


This disease is transmitted by the way of direct contact with


the secretions of mucos membranes such as those of the urethra, cervix, vagina,


anus, eyes and throat.


The contact involved in transmitting gonorrhea is almost always


sexual in nature. It is possible that contaminated fingers can transfer


infection from one region of the body to another, however, this is highly


unlikely because the bacteria dies rapidly when demed the warmth and moisture of


mucous membranes.


Symtoms of infection usually appear within two to ten days after


exposure but might take up to thirty days.


In males, gonorhea usually strikes first at the urethra, the


tube that extends from the bladder to the tip of the penis. A burning sensation


during urination may be experienced due to the irritation of the urethra’s


mucosal lining. Many males may also notice and abnormal discharge from the penis.


The penis itself may be red or swollen at the tip. Urination may become more


frequent or difficult. Occasionally, no symptoms are evident immediately.


In females, gonorrhea seems to strike selectively at the cervix


(the entrance of the uterus, but it also can appear elsewhere. As many as 80% of


the females with gonorhea have no immediate signs or symptoms. One symptom in


women is a foul smelling vaginal discharge. Since vaginal discharges are not


uncommon, women should be alert to any change in the color, odor, or other


appearance of discharges. If gonorrhea has affected the urethra, a women may


experience a burning sensation upon urination.


Gonorrhea can also infect the anal region, the oral cavity, and


the eyes. The period of communicability for gonorrhea is uncertain but probaly


lasts as long as discharge continues, anywhere from three to six months.


Precise diagnosis of gonorrhea requires cuttures of discharge


specimens. Under most circumstances gonorrhea is easily treated. It is now clear


however, that larger and larger doses of penicillin may be necessary to kill


some resistant strains.


Untreated gonorrhea may result in irreversible complications.


Infertlity and sterility can develop in males and females. Gonococcal arthritis


in major joints and a generalized infection that irreversibily damages the brain,


heart, liver and other key organs can be produced in either sex.


The most reliable form of protection is the use of condoms


during sexual episodes. The sexually active individual should also be selective


about sexual partners and stay alert to obvious signs and symptoms of disease.


Gonorrhea is known by such street names as


“clap”,”drip”,”dose”,”strain”, “gleet”, and “jack”.


SYPHILIS


Syphilis is perhaps the best known of all the STD’s. Once


confined to certain parts of the world, syphilis now occurs universally.


Treponema Pallidum is it’s causative agent. It belongs to a group of organisms


that resemble bacteria. Humans provide the only known host for T. Pallidum.


There is no vaceine or other acquired immunity for syphilis. Only about 30% of


the people exposed result in infections.


Syphilis is transmitted by direct contact with infection sores,


called chancres, syphitic skin rashes, or mucous patches on the tongue and mouth


during kissing, necking, petting, or sexual intercourse. It can also be


transmitted from a pregnant woman to a fetus after the fourth month of pregnancy.


The incabation period for syphilis is from ten to ninety days


with twenty on days being the average. The diagnostic blood test for this STD is


likely to be negative during the incubation period.


Syphilis goes through several stages. In its primary stage, it


is characterized by the appearance of a chancre at the first site of infection.


A chancre resmembles a blister, pimple, or raised open sore. It is infectious


and contains a large number of spiral bacteria (spirochetes). Chancres are often


painless and may be hidden in the mouth, throat, vagina, cervix, or anus, making


detection difficult. Chancres tend to heal themselves in two to six weeks but


leave behind thousands of infectious spirochetes. Primary syphilis may be


accompanied by swollen glands near the site of primary infection.


Once the chancre dissappears the secondary stage begins.


Secondary symptoms can occur from six weeks to six months after the primary


infection “disappears”. New symptoms usually include the presence of a rash or


raised leisions anywhere on the skin. The rash is not painful or itchy, but is


infectious. Patches of white in the mouth, nose, or rectum may appear. These


mucous patches can also transmit disease. Additional symptoms at this stage may


include patchy hair loss, mild fever and body aches, swollen glands and flulike


symptoms. Secondary symptoms disappear in two to six weeks but may recur for up


to two years


If still untreated, syphilis enters what is called the latent


stage. At this point, symptoms are absent and the person is probaly no longer


infectious to others. (The exception is the pregnant woman who is still able to


transmit the disease to the unborn child.) The length of the latent stage is


variable but can last at least five years and perhaps as many as twenty years or


more. Some cases of syphilis remain dormant for an indefinite length of time.


Others evolve into the final stage of symptoms.


Tertiary or late-stage syphilis usually occurs between five and


twenty years following initial infection. This condition leads to permanent


disabilities and even death. Neurosiphilis, in which the brain and the spinal


cord are affected, produce paralysis, insanity and blindness. Cardiovadcular


syphilis includes major damage to the heart and the aorta, possibly resulting in


death. Late begin syphilis is characterized by the appearance of large


destructive lesions virtually at any internal or external site.


The period of contagiousness for syphilis is variable. It is


clearly infectious in its primary and secondary stages. Active bacteria are


wipred out in twenty four to forty eight hours by adequete treatment with


penicilline. Infected individuals must be followed closely after treatment and


repeated blood test must be performed to assure the complete absence of the


disease.


People hoping to avoid syphilis must avoid contact with


syphilitic lesions. The use of a condom sharing during sexual intercourse can


assist in this, but a condom will not protect other exposed surfaces.


Syphilis has been nicknamed “syphpox” or “bad blood”.


CHLAMYDIA-RELATED INFECTIONS


Chlamydia trachomatis may be the most common STD in the U.S


today. This organism, an intracellular parasite, is resposbile for more thatn


one disease condition nonspecific urethritis (NSU), or nongonoco

ccal urethritis


(NGU), and lymphogranuloma venereum (LGV) are among these conditions.


NSU involves an inflamation of the urethra. If symptoms are


present they may resemble those of gonorrhea. Chlamydia currently accounts for


approximately 50% of NSU cases. Transmission of NSU, however is probable during


sexual intercourse, and transfer from mother to infant at birth is also possible.


To tell the difference between NSU and gonorrhea, cultures of


smears or discharged must be examined in a laboratory. The treatment for NSU is


telracycline. Both partners should be treated in order to avoid the so-called


“Ping-Pong” effect. The most severe complication of NSU in females is PID


(Pelvic Inflammatory Disease) This condition often leads to infertility. NSDU


can be controlled by using condoms during sexual intercourse, washing the


genitals with soap and water before and after intercourse, and contacting sex


partners when infection presents itself.


C. Trachomatis is also responsible for the STD called (LGV).


Symptoms include sores in the genital area that resemble pimples. It is most


commonly seen among gay men and persons having multiple sex partners.


Transmission occurs through direct contact with lesions, usually during sexual


intercourse. Complications from LGV area rare, though inflamation of the urethra,


cervix, and rectum are possible Tetracycline provides reliable thereapy for this


STD.


GENITAL HERPES


Genital herpes is rapidly gaining attention as an STD. Once


reason is that thousands of new cases are being identified each year. Another


reason is a lack of any known cure. Herpes simplix virus type 2, because it is


viral, makes antibiotic drugs useless in treating the symptoms and eliminating


infection frmo the body. In most cases, the herpes sores blisters and crusty


form on the genitals and heal and disappear on their own in a few days or weeks.


The virus itself, however, stays in a dormant stage: the absence of symptoms


does not necessarily mean the absence of active virus. Herpes may flair up from


time to time, causing the sores to reappear. These sores are usually visible and


painful in both sexes; however, signs of herpes in women can be internal and


painless. It is possible for women to be unaware of the virus’s presence.


It is not well understood what triggers recurrences of herpes.


Towered resistance, other infections, chafing or irritation of the affected area,


emotional upset, and even certain foods are implicated to some extent.


Of a few sensible points are observed, life can continue to be


full and enjoyable. Herpes victims are advised to be especially conecientious


about controlling stress factos that may aggravate the dormant HSV-2 organism.


It is advised that a condom be used during intercourse to provide protection for


the uninfected partner. The person who follows a well-balanced fitness routine


should experience minimal life disruptions resulting from herpes.


Women who have herpes need to take a few extra precautions.


There is an association between HSV-2 infection and the development of cervical


cancer. A woman with herpes may be advised to have pap tests more frequently and


watch for any unusual vaginal bleeding. Because of the danger of infecting the


newborn infant, women who know they have herpes should share that information


with their doctor.


There is no cure for genital herpes at this time. Some relief of


symptoms is available using topical ointments.


CANDIDIASIS (MONILIA)


Candidiasis also known as monilia is a common yeast infection


caused by Candida also known as monilia is a common yeast infection caused by


Canidida albicans. Candidiasis frequently may be acquired by other than sexual


means. It is a normal part of the human flora. Many predisposing factors can


cause an outbreak of the yeast organisms:


Acute infections are accompanied by intense itching at the


infected site, along with redness and perhaps swelling. In women, Candidus may


also produce vaginal discharges of a white, curdlike quality.


The principal complication is recurrence, resulting when the


infection is passed back and forth between partners. Consequently, when flare-


ups occur, both partners are often treated. The most common and reliable


treatment is topical application of nystatin for both partners.


Acute episodes of candidiasis can generally be avoided or


minimized by using condoms during intercourse, wearing clothes that are not


tight fitting, and keeping the genital area dry.


NONSPECIFIC VAGINITUS


Nonspecific Vaginitis (NSV) is thought to be caused by the


bacterium Gordnerella Vaginalis whenever other organisms cannot be identified in


NSV. Symptoms of NSV are almost always restricted to females, though a male may


experience itchy, burning symptoms of disease in his penis, similar to the


vaginal symtoms that females report.


Symptoms in the female include a foul-smelling vaginal discharge,


vaginal itching, and burning, upon urination, however the complete absence of


symptoms is not uncommon treatment is accomplished with oral metronadozole, and


transfer is prevented by the use of condoms.


TRICHOMONIASIS


Trichomoniasis is caused by the presence of Trichomonas


vaginalis, a protozoan, which may exist without symptoms in the vaginal flora of


50 percent of the females in the U.S between the ages of sixteen and twenty-five.


Susceptibility is general, though clinical disease is usually restricted to


females.


Though the organisms can be acquired during sexual intercourse,


they may also be picked up by non-sexual means from freshly soiled bedclothes,


towels and other items.


Symptoms of females with trichomoniasis may include a foul-


smelling discharge, localized itching redness and burning during urination.


Males seldom experience any demonstrable symptoms. Treatment is oral


metronidazole, usually given to both partners since “trich” is another of the


“ping-pong” STD’s


PEDICULOSIS AND SCABIES


Pediculosis and scabies are two disorders labeled infestations


than infections. Both are caused by parasites, pediculosis by the crab louse and


scabies by the itch mites. These organisms may be found anywhere on the body


but show a preference for pubic hair. They lay their eggs at the base of the


hiar, just underneath the skin. Crabs and mites can produce an agonizing itch


after their eggs hatch. Transfer of these organisms can occur from person to


person in a variety of ways. Direct body contact, particularly during physical


intimacy, is a common mode. Contact with personal items can also facilitate


transfer.


Complications are rare though secondary infections can result


from breaks in the skin due to intense itching and irritation. Treatment is


provided by application of medicated shampoos. Good personal hygiene and careful


laundering of clothes and bedding prevent reinfestation.


URINARY TRACT INFECTIONS


Urinary tract infections (UTIs) occur with pathogenic organisms


enter the urethra and migrate to the bladder. Ordinarily they are confined to


the host but they can be sexually transmitted. Bacteria and other organisms may


produce UTI. Women, perhaps because of their shorter urethras, are much more


susceptible to UTIs than men. Pechthogens can sometimes be “flushed” from the


system by having the individual drink large quantities of water. Rersistent


symptoms of UTI should be treated by a physician.
