  1. Head lice Information & Treatments Tracy dickens School Nurse March 2012

  2. Head lice (pediculushumanuscapitus Six legged, no winged insects They live close to the scalp They feed from blood from the head They spread through head to head contact They vary in size from a full stop – about 3-4mm long Female louse lays eggs when she is about 10 days old she will lay about 50-150 eggs during her lifespan Lice are the insects, young lice called nymphs are transparent until after their first blood Meal Lice lay eggs close to the scalp which makes them difficult to detect Nits are the empty shells that stick to the hair shaft

  3. Detection of head lice • 1. CHECK • Parents once a week check your childs head • Wet hair, condition, leave conditioner in, use head lice comb • If lice are detected treatment is advised • Diagnosis can only be made when live louse are found

  4. Treatments: • Four principle treatments • 1.Pesticides two types in the BNF • Malathion – (derbac) • Lice can develop high resistance to chemicals • Favourable safety record • Not recommended if child has eczema/asthma • Can cause skin irritation • Not to be used on broken skin • Eradication rate 33% (Thornton and Ross 2010) • Permethrin – lyclear • not recommended in BNF current preparation too diluted to be effective (BNFC 2011-2012)

  5. 2. Non pesticides: • Dimeticone (Hedrin) • Coat the outside of the louse causing interference with water balance it to die, research suggests that because this is a physical process the lice cannot build resistance. (BNF 2011; NPF 2011) • Less effective against eggs and needs to be repeated after 7 days (BNF 2011) • Eradication rate 97% • Avoids resistance (Thornton and Ross 2010)

  6. 3. Wet combing/bug busting • 38% – 57% effective at eradicating lice • Labour intensive, relies on commitment of both parent and child – therefore cannot be relied upon to tackle at community level (Schweiger 2012) • No chemicals involved therefore preferred by • Some parents

  7. 4. Alternative remedies Electronic devices not suitable for general use Herbal/essential oils Eucalyptus oil/tea tree oils/lavender oil limited evidence to assess their effectiveness some oils can be toxic Some products claim to act as repellents not recommended (Schweiger 2012)

  8. What is the best product? Systematic review of RCTs, Case studies and Cohort studies comparing the above treatment methods found that in all cases Dimeticone was significantly more effective at the eradication of head lice compared to malathion (Burgess et al 2007; Schweizer 2012) Burgess et al (2007) was a small sample for a RCT, total random sample of 73 children with head lice 25 cures and 5 reinfections (Dimeticone) 9 cures and 1 reinfection (malathion)

  9. Which To Choose? • Age – not licensed for under 6 months • Contra-indications – asthma, skin problems • Resistance – what has been tried previously why is it not working • Avoiding resistance • Parent preference
