Enterobius Vermicularis Infection Management

Diagnosis and Treatment

• The American Academy of Pediatrics recommends the "sellotape test" (adhesive tape test) for diagnosing Enterobius vermicularis infection, which involves applying adhesive tape to the perianal region in the morning to collect eggs 1
• The Centers for Disease Control and Prevention suggests concentrated stool microscopy or fecal PCR for diagnosis, though eggs may be absent in stool samples 2
• Visualization of adult worms in the perianal region, particularly at night, can also aid in diagnosis 1
• The World Health Organization recommends Albendazole 400 mg as a single oral dose as the first-line treatment for Enterobius vermicularis infection 2
• Pyrantel pamoate is an alternative treatment, with dosage based on weight 2
• Treatment should be repeated after 2 weeks to address reinfection from eggs that may have hatched after initial treatment 2

Clinical Presentation

• Enterobius vermicularis infection often presents with pruritus ani (intense anal itching), which is the most common symptom 2
• Infection can be frequently asymptomatic in many cases 2
• Possible vulvovaginitis in females can occur due to worm migration into the genital tract 2
• Infection may cause weight loss, irritability, diarrhea, and abdominal pain in some cases 2
• Occasionally, colitis with eosinophilia can occur 2

Management of Pinworm Infection in Young Children

Treatment Options

• For children under 2 years, medication dosing should be carefully considered and may require expert consultation, as recommended by the Centers for Disease Control and Prevention 3
