Phthirus pubis, commonly known as “crabs,” is a tiny parasitic insect that infests human pubic hair. These little creatures can cause itching and discomfort. In this article, we’ll break down everything you need to know about phthirus pubis, including its types, causes, symptoms, diagnostic tests, treatments, and related drugs.
Types of Phthirus Pubis:
Phthirus pubis is a specific type of louse that primarily infests human pubic hair. Unlike head lice or body lice, these tiny parasites are adapted to live in the coarse hair of the pubic region.
Causes of Phthirus Pubis:
- Sexual Contact: The most common way to contract phthirus pubis is through sexual contact with an infected person. The insects can easily transfer from one person to another during intimate activities.
- Sharing Bedding or Clothing: Although less common, sharing bedding or clothing with an infected person can also lead to infestation.
- Close Personal Contact: Close personal contact with an infected person, such as hugging or sitting closely, can sometimes lead to transmission.
- Infested Towels or Linens: Using towels or linens that have been in contact with an infected person’s pubic hair can potentially spread the infestation.
Symptoms of Phthirus Pubis:
Phthirus pubis infestation can cause various uncomfortable symptoms, including:
- Intense Itching: The primary symptom is severe itching in the pubic area, which can be persistent and bothersome.
- Red or Blue Spots: Small red or blue spots may appear in the infested area, resulting from bites or irritation caused by the insects.
- Visible Lice: In some cases, you may be able to see tiny crab-like insects in your pubic hair.
- Secondary Infections: Scratching the itchy area can lead to skin irritation and potential secondary bacterial infections.
- Allergic Reactions: Some individuals may experience allergic reactions to the bites, leading to swelling or hives.
Diagnostic Tests for Phthirus Pubis:
If you suspect you have phthirus pubis, it’s essential to seek a diagnosis from a healthcare professional. They may use the following diagnostic tests:
- Visual Examination: A healthcare provider will closely inspect the pubic area for the presence of lice, eggs (nits), or any signs of irritation.
- Microscopic Examination: In some cases, a sample of pubic hair or skin may be examined under a microscope to confirm the presence of phthirus pubis.
- Self-Examination: You can help by carefully examining your pubic hair for any signs of lice or eggs. Use a magnifying glass if necessary.
- Polymerase Chain Reaction (PCR) Test: In rare cases, a PCR test may be used to confirm the presence of phthirus pubis.
Treatments for Phthirus Pubis:
Treating phthirus pubis is essential to relieve symptoms and prevent its spread. Here are some effective treatment options:
- Over-the-Counter (OTC) Products: Medicated shampoos or creams specifically designed to kill lice can be purchased without a prescription. Follow the product instructions carefully.
- Prescription Medications: In severe cases, a healthcare provider may prescribe stronger medications to eliminate the infestation.
- Manual Removal: Some individuals may opt for manual removal of lice and nits using a fine-toothed comb. This can be time-consuming but effective.
- Washing and Cleaning: Wash all clothing, bedding, and towels that may have come into contact with the infested person in hot water and dry them on high heat. This helps kill any remaining lice or nits.
- Avoidance of Close Contact: To prevent re-infestation, avoid close contact with an infected person until they have been treated and are lice-free.
-
Shaving or Trimming: In some cases, shaving or trimming the pubic hair may be recommended to make it easier to treat and prevent re-infestation.
Drugs for Phthirus Pubis:
Several medications can be used to treat phthirus pubis effectively. Some common options include:
- Permethrin: This topical cream or lotion is available by prescription and works by killing the lice and their eggs.
- Malathion: Another prescription topical treatment that is effective against phthirus pubis.
- Ivermectin: In some cases, healthcare providers may prescribe oral ivermectin to treat the infestation.
- Lindane: Lindane is a prescription medication that should only be used when other treatments have failed due to potential neurotoxicity.
- Benzyl Alcohol: This topical treatment is effective against lice and is available by prescription.
Conclusion:
Phthirus pubis, or “crabs,” may be a discomforting condition, but it is treatable. If you suspect you have an infestation, seek medical advice for proper diagnosis and treatment. Remember to follow the prescribed treatment plan and take necessary precautions to prevent re-infestation and transmission to others.
