Q

What are the pros and cons of developmental screening tools like the Ages and Stages Questionnaire (ASQ)?

A

Pros:

Early identification of delays
Easy to administer
Guides referrals for intervention
Cons:
May miss subtle delays
False positives can cause parental anxiety

21
Q

Why is early intervention important in developmental delay?

A

Early intervention maximizes the child’s potential, improves long-term outcomes, and helps mitigate secondary complications such as social isolation and behavioral challenges.

22
Q

Febrile Convulsions

A

Seizures which occur in children with a high fever between the ages of 6 months and 5 years

23
Q

Simple Febrile Convulsions

A

Simple febrile convulsions are generalised tonic clonic and last less than 15 minutes and only occur once during a single febrile illness

24
Q

Complex Febrile Convulsions

A

Complex febrile convulsions are focal seizures, last more than 15 minutes or occur multiple times during the same febrile seizures

25
Q

Ix for Febrile Convulsions

A

Rule out other causes such as epilepsy, syncopal episode, trauma, space-occupying lesions and neurological infection

26
Q

Management of Febrile Convulsions

A

Identify and manage source of infection - Control fever with simple analgesia - Parental education - Prognosis is slightly higher for seizures/epilepsy in the future

27
Q

Advice for parents with child who has febrile convulsions

A

●Stay with the child ●Put the child in a safe place, for example on a carpeted floor with a pillow under their head
●Place them in the recovery position and away from potential sources of injury
●Don’t put anything in their mouth
●Call an ambulance if the seizure lasts more than 5 minutes

If they have complex febrile convulsions, risk is slightly higher for developing epilepsy compared to the simple febrile convulsions and for ordinary people

28
Q

Epilepsy

A

An umbrella term for a tendency to have seizures which are transient episodes of abnormal electrical activity in the brain.

29
Q

Generalised Tonic-Clonic Seizures

A

Loss of consciousness with tonic (rigidity) and clonic (rhythmic jerking) phase with possible tongue biting, incontinence, groaning and irregular breathing - After this there is a postictal period where the person is confused, drowsy and feels irritable/low

30
Q

Management of Generalised Tonic-Clonic Seizures

A

sodium valproate, lamotrigine or carbamazepine

31
Q

Focal Seizures

A

These begin in the temporal lobes and affect speech, memory and emotions. - They can present with hallucinations, memory flashbacks and deja vu.

32
Q

Management of Focal Seizures

A

lamotrigine or levetiracetam

33
Q

Absence Seizures

A

the become blank and stare into space then abruptly return to normal - During this, they are unaware of their surroundings and will not respond and these generally last for around 10-20 seconds. - Most patients stop having these with age

34
Q

Management of Absence Seizures

A

ethosuximide.

35
Q

Myoclonic Seizures

A

Sudden brief muscle contractions where the person remains awake - These are often part of juvenile myoclonic epilepsy

36
Q

Management of Myoclonic Seizures

A

sodium valproate or levetiracetam

37
Q

Tonic/Atonic Seizures

A

Sudden tension/stiffness affecting the body

38
Q

Management of Tonic/Atonic Seizures

A

sodium valproate or lamotrigine

39
Q

Which is the most common type of seizure in children?

A

Absence Seizures

40
Q

Ix for Epilepsy

A

Full history - EEG should be performed after the second simple tonic-clonic seizures - MRI brain to help diagnose structural abnormalities - Blood electrolytes, glucose, cultures and LP can also be considered

41
Q

Management of Acute Seizures

A

Recovery position if possible - Put something soft under the head to prevent injury - Remove any obstacles that could lead to injury - Make a note of time of start and end of seizures - Call an ambulance if the seizures lasts longer than 5 minutes

42
Q

Side Effects of Sodium Valproate

A

Teratogenic, Liver damage, Hair loss, Tremors

43
Q

Side Effects of Carbamazepine

A
  • Agranulocytosis, Aplastic anaemia
44
Q

Side Effects of Ethosuzimide

A

Night tremors, Rashes, N+V

45
Q

Side Effects of Lamotrigine

A
  • DRESS syndrome, Leukopenia
46
Q

What is DRESS syndrome?

A

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Syndrome

47
Q

Status Epilepticus

A

Medical emergency where a seizures lasts more than 5 minutes or 2 or more seizures without regaining consciousness

48
Q

Management of Status Epilepticus

A

Management includes securing airway, high concentration oxygen, assess cardiac and respiratory function and IV lorazepam which can be repeated after 10 minutes if it continues

49
Q

Medical options to treat Status Epilepticus in the community

A

buccal midazolam and rectal diazepam.
