PUBIC LICE (CRABS), CAUSES, TREATMENT AND PREVENTIONS.



INTRODUCTION.


Pubic lice, commonly called crabs, are tiny insects found in your genital area. They are a different type of louse from head lice and body lice. Measuring 1/16 inch (1.6 millimeters) or less, pubic lice received their nickname because their bodies resemble sea crabs.

The most common way to acquire pubic lice is through sexual intercourse. In children, pubic lice may be found in the eyebrows or eyelashes and can be a sign of sexual abuse. However, children can sometimes catch pubic lice from heavily infested parents simply by sharing a communal bed.


Pubic lice feed on your blood, and their bites can cause severe itching. Treatment includes applying over-the-counter creams and lotions that kill the parasites and their eggs.

SIGNS & SYMPTOMS.

People do not usually get any symptoms until having pubic lice for about five days. Some people never get symptoms. When symptoms do appear, they may include
● intense itching in the genitals or anus
● mild fever
● feeling run-down
● irritability
● the presence of lice or small egg sacs, which are called nits, in pubic hair.

TESTS AND DIAGNOSIS.

The health care provider will do an exam to look for:
Small gray-white oval eggs (nits) attached to the hart shafts in the outer genital area. Adult lice may also be present
Scratch marks or signs of an infection, such as impetigo.
Because pubic lice may cause an eye infection (blepharitis) in young children, eyelashes should be viewed with a high-powered magnifying glass.

If over-the-counter lotions or shampoos (Nix, Rid, others) don't kill your pubic lice, your doctor may prescribe stronger treatments, such as:

Malathion (Ovide) You apply this prescription lotion to the affected area and wash it off after eight to 12 hours.
Ivermectin (Stromectol) This medication is taken as a single dose of two pills, with an option to take another dose in 10 days if the treatment isn't initially successful.
Lindane Because of its toxicity, lindane is usually prescribed only when other treatments fail. You apply lindane to the affected area and wash it off after four minutes. It's not recommend for women who are pregnant or breast-feeding, or for children younger than age 2.
Eye treatments If pubic lice are found in eyelashes, you can treat them by applying petroleum jelly to your eyelid and lashes three times a day for several days. In addition, or as an alternative, the lice and nits can be gently removed from eyelashes using tweezers, a nit comb or your fingernails. Your doctor may also prescribe a medicine to apply to the eyelids.

COMPLICATIONS.

A pubic lice infestation sometimes leads to complications such as:
Discolored skin Pale blue spots may develop where pubic lice have been feeding continually.
Secondary infections If itchy lice bites cause you to scratch yourself raw, these wounds can become infected.
Eye irritations Children who have pubic lice on their eyelashes may develop a type of pink eye (conjunctivitis).

PREVENTION.
Pubic lice are easily spread, and there is no protection. The only thing that can reduce your risk of getting pubic lice is limiting the number of people with whom you have intimate or sexual contact. If you or your partner has pubic lice, do not have sex again until treatment is complete.
