Pediculosis Pubis
Pediculosis pubis, also known as crabs or pubic lice, is a parasitic infestation of the pubic area caused by the crab louse (Pthirus pubis).
Causes and Transmission
Pediculosis pubis is usually spread through direct skin-to-skin contact with an infected person, typically during sexual activity. It can also be transmitted through sharing of personal items such as towels, bedding, or clothing that have come into contact with an infected person.
Symptoms
The symptoms of pediculosis pubis may include:
- Intense itching in the pubic area, especially at night
- Visible lice or eggs (nits) in the pubic hair
- Small, bluish-gray spots on the skin (due to the louse's bites)
- Irritation and inflammation of the affected area
Diagnosis
Pediculosis pubis is typically diagnosed through a visual examination of the pubic area, where the presence of lice or eggs can be seen. A magnifying glass or microscope may be used to confirm the diagnosis.
Treatment
Treatment for pediculosis pubis usually involves the use of over-the-counter (OTC) medications such as:
- Permethrin cream rinse (1%)
- Pyrethrin shampoo
- Lindane shampoo (although this is less commonly used due to potential side effects)
It is essential to follow the instructions carefully and complete the full treatment course to ensure that all lice and eggs are eliminated. Additionally, it is recommended to:
- Wash and dry clothing, bedding, and towels in hot water and high heat
- Vacuum carpets and furniture, especially in areas where the infected person has been
- Avoid sharing personal items
Prevention
To prevent pediculosis pubis, it is recommended to:
- Avoid direct skin-to-skin contact with an infected person
- Avoid sharing personal items such as towels, bedding, or clothing
- Use protective measures during sexual activity, such as condoms
- Regularly wash and dry clothing, bedding, and towels in hot water and high heat
Complications
If left untreated, pediculosis pubis can lead to secondary infections, such as bacterial or fungal infections, due to scratching and irritation of the affected area.
