Cellulitis presents with an acute onset of red, painful, hot, swollen, and tender skin, with possible blister or bullae formation. The leg is the most commonly affected site, presentation is usually unilateral. Often (but not always) associated with a break in the skin (portal entry).
If patient afebrile and tolerating oral antibiotics, can be managed in primary care. Caution with immunocompromised patients.
Most children with infected eczema do not benefit from antibiotic therapy (oral or topical) - except those with a severe infection. Optimisation of topical steroids is the mainstay of treatment in these patients.
Most children with cellulitis or impetigo do not require skin swabs sent, unless portal of entry, extensive infection, not responding to treatment or recurrent episodes. If recurrent or severe staph aureus infection, consider requesting PVL testing.
For limited non-bullous impetigo, use a topical antiseptic, such as hydrogen peroxide 1% cream applied 2 to 3 times a day for 5-7 days
or
topical Abs (fusidic acid 2% cream or mupirocin 2% ointment) tds for 5-7 days.
Cefalexin for 5-7 days. 12.5mg/kg bd (max 1g per dose) or 1-11 months: 125mg bd. 1 year - 4 years: 125mg tds. 5-11 years: 250mg tds. 12 years and over: 500mg bd-tds.
Flucloxacillin for 5-7 days. 1-23 months: 62.5-125mg qds. 2-9 years: 125-250mg qds. 10-17 years: 250-500mg qds.
If facial cellulitis, Co-amoxiclav for 5-7 days. 1-11 months: 0.25 mL/kg of 125/31 co-amoxiclav liquid tds. 1-5 years: co-amoxiclav 125/31 liquid 5mL tds. 6-11 years co-amoxiclav 250/62 liquid 5mL tds. 12-17 years co-amoxiclav 250/62 liquid 10mL tds.
If allergic to penicillin: Clarithromycin for 5-7 days. Dose: Under 8kg: 7.5 mg/kg bd. 8 to 11kg: 62.5 mg bd. 12 to 19kg: 125 mg bd. 20 to 29kg: 187.5 mg bd. 30 to 40kg: 250mg bd. 12 to 17 years: co-amoxiclav tablets (500/125mg) 1 tds or co-amoxiclav 250/62 liquid 10 mL tds.
Provide safety netting information (verbal and written).
Note: aim to use an antibiotic that minimises dosing frequency and is palatable (if suspension prescribed) to optimise adherence. QDS penicillin V and flucloxacillin suspensions are not well tolerated by children. It can sometimes be challenging for children to swallow large volumes of suspensions. Most school age children (from above 4 years of age) can be taught to swallow tablets.

Usually no treatment required; viral cause most likely (adenovirus, enterovirus, occasionally herpes simplex). Consider ophthalmia neonatorum in a neonate; this does not refer to a simple "sticky eye" in a neonate and requires urgent review in hospital
Consider chloramphenicol eye drops 0.5% and chloramphenicol ointment 1%. Continue until 2 days after symptoms resolved.

Acute otitis media resolves in 60% by 24 hours without Abs. Abs only marginally reduces pain at 2 days (NNT 15) and does not prevent deafness. Need to treat 4800 with antibiotics to avoid 1 case of mastoiditis.
If ear discharge but systemically well and apyrexial, treat with topical antibiotics (sofradex or neomycin) for 10 days.

Click here to listen to a podcast on respiratory tract infections in children.
Most lower respiratory tract infections are of viral aetiology - consider bacterial pneumonia if persistent/recurrent fever over preceding 24-48 hours with chest wall recession and tachypnoea. Presence of generalised wheeze makes viral aetiology far more likely.
First line if antibiotics indicated: Amoxicillin bd for 5 days. Dose per actual body weight (40mg/kg bd (max 1g per dose)) or using age bands (3-11 months 125mg tds (off-label); 1-4 years: 250mg rds or 500mg bd (off-label); 5-11 years: 500mg tds or 750mg bd (off-label); ≥12 years: 600mg tds or 1 gram bd (off-label))
If no response to amoxicillin or consider if high risk of complications:
Co-amoxiclav tds for 5 days. Dose: 1-11 months: 0.25 m:/kg of 125/31 co-amoxiclav liquid tds. 1-5 years: co-amoxiclav 125/31 liquid 5 mL tds. 6-11 years: co-amoxiclav 250/62 liquid 5 mL tds. 12-17 years: co-amoxiclav tablets (500/125 mg) 1 tds or co-amoxiclav 250/62 liquid 10 mL tds.
Treatment for atypical infections should only be considered in severe infection if no response to first line empirical therapy/if allergic to penicillin:
Erythromycin for 5 days. Dose: 1-23 months: 250mg bd. 2-7 years: 500mg bd. 8-17 years: 1g bd.
If severe or complicated pneumonia (O² sats<85%, haemodynamic instability/septicaemia, immunocompromised, chronic lung disease, congenital hear disease, empyema, necrotising pneumonia), for urgent review in hospital - call paediatrician..
Provide safety netting information (verbal and written) (under 1's) (over 1's).
Note: aim to use an antibiotic that minimises dosing frequency and is palatable (if suspension prescribed) to optimise adherence. QDS penicillin V and flucloxacillin suspensions are not well tolerated by children.

Generally, Abs are not required as 80% resolve within 14 days without Tx (NNT 15). Offer adequate analgesia.
Consider treating if most of the following are present:
For children 12 years or older consider prescribing high-dose nasal corticosteroids (equivalent to mometasone 400 micrograms a day) for 14 days instead of:
First line: Amoxicillin if no previous treatment in preceding 4 weeks. Dose: bd for 5 days. Dose per actual body weight (40mg/kg bd (max 1g per dose)) or using age bands (3-11 months: 125mg tds or 250mg bd (off-label); 1 year - 4 years: 250mg tds or 500mg bd (off-label); 5-11 years:500mg tds or 750mg bd (off-label) >12 years: 500mg tds or 1 gram bd (off-label)).
Phenoxymethylpenicillin for 5 days. Dose: 1 to 11 months: 62.5mg qds or 125mg bd (off-label). 1 to 5 years. 125mg qds or 250mg bd (off-label). 6 to 11 years: 250mg qds or 500mg bd (off-label). 12 to 17 years: 500mg qds or 1g bd (off-label).
If treatment with amoxicillin in preceding 4 weeks: Co-amoxiclav tds for 5 days. For children 1-11 months: 0.25ml/kg of co-amoxiclav 125/31 liquid tds.1 years - 5 years: co-amoxiclav 125/31 5 ml tds; 6-11 years: co-amoxiclav 250/62 5 ml tds; 12-17 years: co-amoxiclav tablets (500/125mg) tds or co-amoxiclav 250/62 10 mL tds)
If allergic to penicillin: Clarithromycin for 5 days. Dose: Under 8kg: 7.5mg/kg bd. 8 to 11kg: 62.5mg bd. 12 to 19kg: 125mg bd. 20 to 29kg: 187.5mg bd. 20 to 40kg: 250mg bd. 12 to 17 years: 500mg bd.
Doxycycline (5-day course in total) 12 to 17 years: 200mg on first day, then 100mg once a day for 4 days.
Note: aim to use an antibiotic that minimises doing frequency and is palatable (if suspension prescribed) to optimise adherence. QDS penicillin V and flucloxacillin suspensions are not well tolerated by children. It can sometimes be challenging for children to swallow large volumes of suspensions.

10. NICE guideline – sinusitis (acute): antimicrobial prescribing (2017). www.nice.org.uk/guidance/ng79
Most young children presenting with tonsillitis have a viral aetiology. No significant difference in pain score at day 3 in children treated with antibiotics compared to those treated with placebo (Cochrane review 2013). Need to treat >4000 children with antibiotics to prevent one case of quinsy.
Most children with tonsillitis do not require a throat swab.
Base decision to treat on FeverPAIN score (1 point for each of Fever, Purulence, Attend within 3 days of onset or less, severely Inflamed tonsils, No cough or coryza):
NOTE: if a child's symptoms are worsening after 3 days, think about other differentials including a peritonsillar abscess (quinsy) or Lemierre syndrome (Fusobacterium).
For children unable to swallow tablets; amoxicillin 40mg/kg bd (max 1g per dose) for 7 days. Dose per actual body weight (40mg/kg bd (max 1g per dose)) or using age bands (3-11 months: 125mg tds or 250mg bd (off-label); 1 year - 4 years: 250mg tds or 500mg bd(off-label); 5-11 years: 500mg tds or 750mg bd (off-label); >12 years: 500mg tds or 1 gram bd (off-label)).
Phenoxymethylpenicillin (Penicillin V) for 7 days. Dose: 1-11 months: 125mg bd. 1-5 years: 250mg bd. 6-11 years: 500mg bd. 12-17 years: 1g bd.
Although there has been great anxiety about prescribing amoxicillin in patients with tonsillitis due to the risk of adverse events associated with EBV, there is considerable data to suggest that the use of amoxicillin does not significantly increase the risk of rash in acute EBV – see https://adc.bmj.com/content/101/5/500 . In addition, data suggests that EBV accounts for as little as 1% of tonsillitis presenting to doctors - see https://www.ncbi.nlm.nih.gov/pubmed/17904463 and more importantly, EBV is extremely rare prior in children below 12 years of age. For this reason, the current recommendation is to use amoxicillin suspension in young children (palatability) and penicillin V tablets for children able to swallow tablets (due to higher rates of EBV in this age group).
For children able to swallow tablets; Phenoxymethylpenicillin (Penicillin V) for 7 days. 6-11 years: 500mg bd. 12 years or over: 1g bd.
If allergic to penicillin: Clarithromycin for 5 days. Dose: 1 month to 11 years: Under 8kg: 7.5,g/kg bd. 8 to 11kg: 62.5mg bd. 12 to 19kg: 125mg bd. 20 to 29kg: 187.5mg bd. 30 to 40kg: 250mg bd. 12 to 17 years: 250mg to 500mg bd.
Erythromycin for 5 days. Dose: 1 month to 1 year: 250mg bd. 2-7 years: 500mg bd. 8-17 years: 500mg to 1g bd.
