Pubic Lice

Pubic Lice also called crab lice or "crabs," pubic lice are parasitic insects found primarily in the pubic or genital area of humans. Pubic lice infestation is found worldwide and occurs in all races, ethnic groups, and levels of society.

Pubic lice usually are found in the genital area on pubic hair; but they may occasionally be found on other coarse body hair, such as hair on the legs, armpits, mustache, beard, eyebrows, or eyelashes. Pubic lice on the eyebrows or eyelashes of children may be a sign of sexual exposure or abuse.

Pubic lice have forms: the egg (also called a nit), the nymph, and the adult.

Nit: Nits are lice eggs. They can be hard to see and are found firmly attached to the hair shaft. They are oval and usually yellow to white. Pubic lice nits take about 6-10 days to hatch.

Nymph: The nymph is an immature louse that hatches from the nit (egg). A nymph looks like an adult pubic louse but it is smaller. Pubic lice nymphs take about 2-3 weeks after hatching to mature into adults capable of reproducing. To live, a nymph must feed on blood.

Adult: The adult pubic louse resembles a miniature crab when viewed through a strong magnifying glass. Pubic lice have six legs; their two front legs are very large and look like the pincher claws of a crab. This is how they got the nickname "crabs." Pubic lice are tan to grayish-white in color. Females lay nits and are usually larger than males. To live, lice must feed on blood. If the louse falls off a person, it dies within 1-2 days.

PID

Pelvic inflammatory disease (PID) is an infection of the female reproductive organs. It usually occurs when sexually transmitted bacteria spread from your vagina to your uterus and upper genital tract. Many women who develop pelvic inflammatory disease either experience no signs or symptoms or don't seek treatment. Pelvic inflammatory disease may be detected only later when you have trouble getting pregnant or if you develop chronic pelvic pain.

Symptoms in PID range from subclinical (asymptomatic) to severe. If there are symptoms, then fever, cervical motion tenderness, lower abdominal pain, new or different discharge, painful intercourse, or irregular menstrual bleeding may be noted. It is important to note that even asymptomatic PID can and does cause serious harm. Laparoscopic identification is helpful in diagnosing tubal disease, 65–90% positive predictive value in patients with presumed PID. Regular Sexually Transmitted Infection (STI) testing is important for prevention. Treatment is usually started empirically because of the serious complications that may result from delayed treatment. Definitive criteria include: histopathologic evidence of endometritis, thickened filled fallopian tubes, or laparoscopic findings. Gram-stain/smear becomes important in identification of rare and possibly more serious organisms.

A woman can get PID if bacteria (germs) move up from her vagina and infect her pelvic organs. Many different types of bacteria can cause PID. But, most cases of PID are caused by bacteria that cause 2 common sexually transmitted infections (STIs) — gonorrhea and chlamydia. It can take from a few days to a few months for an infection to travel up from the vagina to the pelvic organs.

You can get PID without having an STI. Normal bacteria found in the vagina and on the cervix can sometimes cause PID. No one is sure why this happens.

HPV

Human papillomavirus or HPV, is the name for a group of viruses that includes more than 100 types. More than 40 types of HPV can be passed through sexual contact.

The types of HPV that infect the genital area are called genital HPV. Over half of sexually active people will have HPV at some point in their lives. But most people never know it. This is because HPV most often has no symptoms and goes away on its own.

HPV is passed on through genital contact, most often during vaginal and anal sex. HPV may also be passed on during oral sex and genital-to-genital contact. HPV can be passed on between straight and same-sex partners—even when the infected partner has no signs or symptoms.

A person can have HPV even if years have passed since he or she had sexual contact with an infected person. Most infected persons do not realize they are infected or that they are passing the virus on to a sex partner. It is also possible to get more than one type of HPV. Very rarely, a pregnant woman with genital HPV can pass HPV to her baby during delivery. In these cases, the child can develop Recurrent Respiratory Papillomatosis (RRP), a rare condition in which warts grow in the throat. In children, this is also referred to as juvenile-onset Recurrent Respiratory Papillomatosis (JORRP).

HIV/Aids
Persons initially infected with HIV may develop an "acute retroviral syndrome" characterized by fever, lymph node enlargement, and flu-like symptoms. If symptoms are present, they clear spontaneously, but all infected persons, both with and without symptoms, remain infected and infectious to others indefinitely. The incubation period is highly variable, averaging about a decade, but ranging from a few months or years to possibly longer than two decades. When sufficient damage to the immune system has been sustained, measured either by laboratory cell counts of the Thelper cells or by onset of opportunistic infections, the patient is said to have AIDS. Common manifestations of HIV infection include tiredness, lymph node enlargement, fever, weight loss, and yeast infections of the mouth and vagina.

HIV infection is diagnosed by laboratory detection of evidence of infection, usually identification of HIV-specific antibodies in a blood, oral fluid, or urine specimen. AIDS can be diagnosed in HIV-infected persons in several ways, based on either laboratory evidence of immunodeficiency (lowered levels of CD4+ cells), or clinically by onset of any one or more of a specific list of opportunistic diseases. Opportunistic diseases are those that occur only, or most severely, in patients whose immune systems are impaired. The most common opportunistic diseases in AIDS patients are Pneumocystis carinii pneumonia, Kaposi's sarcoma, toxoplasmosis of the brain, tuberculosis and other mycobacterial infections, and severe herpes, cytomegalo virus, and yeast infections.

How the AIDS Virus Works?
The AIDS virus weakens the immune system (“immune deficiency”), allowing other infections to ravage the body. These infections are called “opportunistic” because they take advantage of the opportunity to live where the body’s immune system would normally destroy them. It’s when these opportunistic infections strike that the person is said to have AIDS.

Genital Warts

Genital warts (or Condylomata acuminata, venereal warts, anal warts and anogenital warts) is a highly contagious sexually transmitted disease caused by some sub-types of human papillomavirus (HPV).
Genital warts are flesh-colored or gray growths found in the genital area and anal region in both men and women.

It is spread through direct skin-to-skin contact during oral, genital, or anal sex with an infected partner.
Genital warts affect both men and women and can occur at any age.
Most patients with genital warts are between the ages of 17-33 years. Genital warts are highly contagious. There is around a 60% risk of getting the infection from a single sexual contact with someone who has genital warts.

Whilst of those infected with genital HPV it is estimated that only a "small percentage" (between 1% and 5%) develop genital warts, those infected can still transmit the virus. Other types of HPV also cause cervical cancer and probably most anal cancers, however it is important to underline that the types of HPV that cause the overwhelming majority of genital warts are not the same as those that can potentially increase the risk of genital or anal cancer.

Although genital warts are painless, they may be bothersome because of their location, size, or due to itching.

You can’t get genital warts from hugging, sharing baths or towels, from swimming pools, toilet seats, cups or cutlery.

Symptoms
Genital warts are usually painless and do not pose a serious threat to a person’s health. However, they can appear unsightly and cause psychological distress.

What Does Everyone Need to Know About STDs?

Sexually transmitted infections (STI), also previously referred to as sexually transmitted diseases (STD) and venereal diseases (VD), are illnesses that have a significant probability of transmission between humans by means of human sexual behavior, including vaginal intercourse, oral sex, and anal sex. While in the past, these illnesses have mostly been referred to as STDs or VD, in recent years the term sexually transmitted infections (STIs) has been preferred, as it has a broader range of meaning; a person may be infected, and may potentially infect others, without having a disease. Some STIs can also be transmitted via the use of IV drug needles after its use by an infected person, as well as through childbirth or breastfeeding. Sexually transmitted infections have been well known for hundreds of years.

Everyone, young or old, rich or poor, sexually active or not, needs to know a few important facts about sexually transmitted diseases. It’s particularly important that, if we are parents, we spend time throughout our children’s lives discussing these issues in an age-appropriate manner. The more educated our children and teens are about the facts about sexually transmitted diseases, the better the chance is that if they do decide to have sex they will know how to protect themselves from sexually transmitted diseases and infections, as well as HIV the virus that causes AIDS, and unplanned pregnancy.

Sexually transmitted diseases do not discriminate. You can be any age, race, religion, financially secure or insecure, any education level and hold any job from blue collar to CEO. The point is anyone who participates in sexual activity is at risk of contracting a sexually transmitted disease or infection.

It may not surprise you to know that the majority – two-thirds – of all sexually transmitted diseases occur in teenagers and young adults under the age of twenty-five years old. Even with all the education and resources available today, sadly, the number of cases of STDs continues to rise.

Some ways to reduce the chance of having sexual contact with a member of the infected pool, and thus of becoming part of that pool include:

- Stop having sex until you see a doctor and are treated.
- Follow your doctor's instructions for treatment.
- Use condoms and/or microbicide whenever you have sex, especially with new partners.
- Don't resume having sex unless your doctor says it's OK.
- Return to your doctor to get rechecked.
- Be sure your sex partner or partners also are treated.

(The Excerpt of) Potential Impact of Vaginal Microbicides on HIV Risk Among Women with Primary Heterosexual Partners

James M. McMahon, PhD, Associate Professor, Kathleen M. Morrow, PhD, Associate Professor, Margaret Weeks, PhD, Professor, Dianne Morrison-Beedy, PhD, RN, FNAP, WHAP, Professor and Dean, and Amanda Coyle, APRN, Senior Associate

Over the past 2 decades women have increasingly shouldered the burden of the global HIV pandemic (Joint United Nations Programme on HIV/AIDS [UNAIDS], 2004), with the majority of infected women acquiring HIV through sexual contact with a primary male partner (O’Leary, 2000). These trends are the result of multiple factors. Women may be biologically more susceptible to heterosexual transmission of HIV than men, especially via receptive anal intercourse (Boily et al., 2009; Mastro & Kitayaporn, 1998; Padian, Shiboski, & Jewell, 1991). 

In addition, gender-based social inequalities limit women’s options with regard to protective sexual behavior (Higgins, Hoffman, & Dworkin, 2010; Quinn & Overbaugh, 2005; Remien, Halkitis, O’Leary, Wolitski, & Gomez, 2005). Latex condoms, currently the only effective form of barrier protection against HIV, are under the control of men, who often are unwilling to use them, especially in the context of primary relationships (Conley & Collins, 2005).

Vaginal microbicides represent a female-initiated form of barrier and/or chemical protection that can potentially empower women with a means of self-protection. Vaginal microbicides are self-administered chemical compounds, most commonly in the form of a gel, that women can apply intravaginally prior to sexual intercourse to prevent or reduce HIV transmission. Modeling studies indicate that even a partially effective microbicide could have a major impact on the global HIV pandemic (Watts, 2002). 

While it is anticipated that the first generation of vaginalmicrobicides will be less effective at preventing HIV than latex condoms, the enormous potential of this new technology lies in its enhanced acceptability and usability by women. As our experience with the female condom has demonstrated, the importance of the acceptability of any new HIV prevention technology cannot be overstated (Kaler, 2004). It is therefore critically important that the public health sector in the United States prepare for the introduction of commercially available vaginal microbicides (Van de Wijgert & Coggins, 2002). While many American women have expressed a keen interest in vaginal microbicides (Darroch & Frost, 1999), the issues surrounding their acceptability and preference in relation to condom use are complex and have not received adequate attention. One complexity involves the potential reduction of condom use that might result from the introduction and adoption of microbicides.

Gardnerella & Candidiasis (1)

When women are experiencing issues with their reproductive tract it's important to determine what the problem is and the way to treat it best.
In the case of Gardneralla and vaginal Candidiasis it can be confusing for women to know which one of these infections they might have.

This is a problem since Gardnerella and Candidiasis are treated in entirely different ways.

If a woman thinks she has Candidiasis and then goes and gets an over the counter treatment for yeast infections, but at the same time has Gardnerella, then she is not only wasting her money, but also not treating the infection.
Infections left untreated only get worse.

Gardnerella is caused by bacteria infecting the female reproductive tract and it is referred to as bacterial vaginosis.

This overgrowth of bacteria can be brought on by having unprotected sexual intercourse with a partner who is infected with the Gardnerella vaginalis bacteria, however, it has been contracted in some cases non-sexually too.

Women with Gardnerella will have a grey or yellowish discharge when infected and it will produce a strong fishy odor especially when washed with alkaline based soaps.

Women will experience little to no irritation when infected with Gardnerella and the noticably symptom is the odor.

A doctor will prescribe an antibiotic to treat the infection and sexual partners should also be treated.

Douching can help with the odor, but will not treat the infection.


Vaginal Candidiasis

Candidiasis, on the other hand is caused by the fungus Candida albicans and occurs when there is an overgrowth of the yeast cells in the vagina as a result of antibiotics, weakened immune systems, poor diet, or sexual transmission.
