11. AKT: Paediatrics Flashcards
What is Sever’s disease?
- AKA calcaneal apophysitis
- It is a common cause of heel pain in childhood and early adolescence
- Occurs in children who are highly active, particularly in sports involving running and jumping
- Repeated running and jumping leads to a small injury where he calf muscle tendon attaches to the heel bone
Management of Sever’s disease?
- Temporary stop or modification of activities
- Symptoms can be managed with ice packs
- Sports shoes should be comfortable
- Inserting gel heel pads into shoes
- Daily calf-stretching exercises (especially before and after sports)
- Pain usually settles within 6-12 months
When do symptoms of hand, foot and mouth disease usually start?
Symptoms usually start 3-7 days after becoming infected and can last from 7-10 days
Clinical presentation of hand, foot and mouth disease?
Tired
Fever
Rash - can look either like:
* Small, oval white blisters on the palms, soles of the feet, and in mouth
* A red skin rash with a brown scale on it. Rash appears on the outer arms, hands, legs, feet, around the mouth and upper buttocks
Blisters should not be itchy
What is the most common cause of hand, foot and mouth disease?
Coxsackie virus
When can children with hand, foot and mouth disease return to school/daycare?
Until all fluid in their blisters has dried
Potential complications of hand, foot and mouth disease?
- Severe hydration
- Meningitis
- Pleuritis/myocarditis
- Onychomadesis (nail shedding) - occurs 2 months after the illness
Define oppositional defiant disorder
Child/adolescent: Persistent pattern of angry or irritable mood, argumentative or defiant behavir and vindictiveness in social, school or work settings
Define conduct disorder
Child/adolescent: persistent pattern of aggression toward people or animals, destruction of property, deceitfulness or theft, and serious violation of rules
Define antisocial personality disorder
Adult: behaviours constituting a pervasive pattern of disregard for and violation of the rights of others that begins in childhood or early adolescence
What are some differential diagnoses for conduct disorder?
- Oppositional defiant disorder: defiant but not a violation of rights
- Intermittent explosive disorder: impulsive, rather than planned
- Attention deficit hyperactivity disorder
- Disruptive mood dysregulation disorder
- Major depressive disorder
- Bipolar disorder
- Adjustment disorder
- Substance use disorder

Clinical features of infantile acne?
- Onset: usually starts after age 3 months
- Rash: comedones, papules and pustules on cheeks and chin
- Diagnosis: must have comedones present
- Most cases are mild and resolve by 12 months; however, large comedones can leave permanent pits
Management of infantile acne?
Benzoyl peroxide 5% cream or gel topically, daily
Clinical features of toxic erythema of the newborn?
- Affects 50% of full term neonates (uncommon in premature babies)
- Scattered pink or red marks often with papules and weals scattered over face and rest of the body
- Lesions are transient
- Spares the palms and soles
- Resolves spontaneously over 1-2 days
Clinical features of milia?
- Tiny white spots due to accumulation of sweat in blocked pores
- Most resolve within 4 weeks of life
Diagnostic criteria for Kawasaki’s disease?
Presence of prolonged unexplained fever for 5 or more days (fever > 38.5C) with atleast 4 of the following:
* Bilateral non-exudative conjunctivitis
* Polymorphous rash
* Cervical lymphadenopathy
* Mucositis - cracked red lips, injected pharynx or strawberry tongue
* Extremity changes - erythema of palms/soles, oedema of hands/feet (acute phase), and periungual desquamation (convalescent phase)
Incomplete cases (i.e. patients who do not fulfil the strict criteria for diagnosis of Kawasaki’s disease but develop coronary artery lesions) are relative common, especially under 1 year of age; suspect the diagnosis in any child with 5 days of unexplained fever and any 1 of the cardinal clinical features
Describe the rash in Kawasaki’s disease
Usually begins during the first few days of illness, typically as perineal erythema and desquamation, followed by macular, morbilliform, or targetoid skin lesions of the trunk and extremeties
What are the key aspects of management for Kawasaki’s disease?
- Intravenous immunoglobulin - reduces risk of coronary artery aneurysms
- Aspirin - high dose if febrile, low dose if afebrile - continued until follow up echocardiography
- Echocardiography 6 weeks after fever resolution
Clinical features of impetigo?
- Sores usually become coated with a tan/yellowish crust (honey covered look)
- Superficial peeling on the edge of the sore
- Usually itchy
Non-pharmacological management of impetigo?
- Daily 10 minute bleach bath may help reduce amount of bacteria on skin
- Remove crusts from sores with an unused, wet, disposable cloth before applying ointments
- Cover the sores with a watertight dressing and cut child’s fingernails to reduce scratching
- Isolate children until atleast 24 hours after starting medical treatment - keep sores covered
- Wash clothes, towels and bed linen separately from the rest of the family in hot water and dry in sunshine or a hot tumble dryer
- Toys can be washed using a mild disinfectant
Causes of impetigo?
- Non-endemic (non-remote communities): Staph aureus
- Endemic (e.g. remote communities): Strep pyogenes
Pharmacological managemet of impetigo?
Non-endemic:
* Localised skin sores: mupirocin 2% ointment or cream topically to crusted areas, Q8hourly for 5 days
* Multiple skin sores or recurrent infection: Dicloxacillin/flucloxacillin 500mg PO, Q6hourly for 7 days
* Severe penicillin allergy: Trimethoprim+sulfamethoxazole 160+800mg PO, Q12hourly for 3 days
Endemic:
* Benzathine benzylpenicillin IM as a single dose - 1.2million units OR
* Trimethoprim+sulfamethoxazole 160+800mg PO, Q12hourly for 3 days
What age do permanent central incisors erupt?
6-7 years of age
How do you ensure good oral hygiene after dental injury?
- Swab the area with 0.1% chlorhexidine twice a day for 10-14 days to reduce the risk of infection
- Soft diet will also allow loose teeth to become firmer
How do you manage a dental avulsion (complete displacement from socket) of a permanent tooth?
- Refer to dental hospital registrar
- Place tooth in milk or saline (do not use water or scrub tooth)
- Do not handle tooth root
- If possible, return tooth to socket and bite down with gauze to hold tooth in position, support tooth with alfoil wrap
- Best prognosis if “dry-time” less than 60 minutes
