Study Notes

Pinworm Infection: A Common Helminthic Infection

Epidemiology: Most common helminthic infection in the United States and Western Europe, affecting an estimated 40 million people.
Transmission: Primarily human-to-human via contaminated fingers, fomites, or oral-anal sexual contact. Eggs can survive in the environment for days, especially under humid conditions, facilitating reinfection and spread within families.
Symptoms: Often asymptomatic, but may cause perianal itching, abdominal discomfort, nausea, insomnia, and nervousnes. In rare cases, complications like skin infections from scratching, female genital tract helminth infections, and diarrhea can occur.
Diagnosis: Visualization of eggs in perianal area using cellophane tape or commercially available adhesive devices followed by microscopic examination.
Treatment: Pyrantel Pamoate is the drug of choice, available over-the-counter under brand names Pin-X® and Reese's® Pinworm Medicine.
- Mechanism of Action: Paralyzes the worms, facilitating their expulsion in stool.
- Dosage: Single oral dose of 11 mg/kg or 5 mg/lb, up to a maximum of 1 gram. A second dose may be needed in 2 weeks if symptoms persist.
- Household Contacts: All members in close contact with the infected patient should also receive treatment.
Special Populations:
- Pregnancy: Treatment in pregnant women needs to weigh the risk of the infection versus the potential risks of medication.
- Lactation: Pyrantel pamoate is considered safe for breastfeeding mothers.
- Children: Risk-benefit assessment is essential when treating children.
Patient Education:
- Hygiene: Regular bathing, especially upon waking up, helps reduce egg contamination. Thorough handwashing after using the toilet, before eating, and after diaper changes is crucial.
- Environmental Hygiene: Disinfect toilet seats. Frequent changing of underwear, nightclothes, and bed sheets is vital, especially for the infected patient and family members.
- Nail Care: Trim and scrub fingernails regularly to reduce the risk of self-reinfection.
- Behavior Modification: Discourage nail biting and unnecessary scratching of the anal area.

Preventing Pinworm Infections

Frequent washing of hands after going to the toilet and before meals.
Trim fingernails short and regularly.
Avoid nail biting and scratching the anal area.
Thoroughly wash underwear, nightclothes, and bed sheets after each treatment.
Disinfect toilet seats after use.
Keep bedroom blinds open during the day, as sunlight is detrimental to eggs.

Additional Points to Remember:

Role of the Pharmacist: Provide comprehensive information about the infection, treatment, and prevention strategies to patients.
Reinfection Sources: Thoroughly investigating to identify the source of reinfection is vital, especially in situations where treatment fails. Potential sources include other household members, playmates, classmates, or even shared spaces and objects.
Self-Treatment: Consider excluding self-treatment in patients with debilitating symptoms, severe diarrhea, constipation, GI bleeding, unintentional weight loss, pregnancy or lactation concerns.
LactMed Database: A valuable resource for information about drugs and their compatibility with breastfeeding.
Importance of Retrieval: Testing yourself or actively retrieving information from memory is a more effective learning strategy than simply rereading material.
