Q

What happens during a reflex anoxic seizure / pallid breath holding spell?

A

A

When the misaligned eye becomes ‘lazy’ because the other one becomes dominant. The ‘lazy eye’ becomes more disconnected from the brain, making the problem worse.

29
Q

What is cerebral palsy?

A

Permanent neurological problems occurring due to damage to the brain around the time of birth. This means there is a huge variation in severity and type of symptoms.

30

  • dieticians
  • ortho surgeons - e.g. to release contractures
  • medications such as muscle relaxants, anti-epileptics etc.
  • social workers and support groups
46
Q

What is syncope?

A

Temporary loss of consciousness due to a disruption of blood supply to the brain, often causing a fall. Also known as vasovagal or fainting.

47
Q

What happens during a vasovagal episode?

A
  • vagus nerve receives a strong stimuli - e,g, emotional event, pain, change in temp
  • stimulates parasympathetic nervous system
  • causes vasodilation, hence dropping the blood pressure in the cerebral circulation
  • leading to hypo perfusion and then a loss of consciousness
48
Q

What are the signs and syndromes of the prodrome before syncope?

A
  • hot or clammy
  • sweaty
  • heavy
  • dizzy or lightheaded
  • vision going blurry or dark
  • headache
49
Q

What can cause syncope?

A

Primary
- dehydration, missed meals, extended standing, vasovagal response to a stimuli
Secondary
- hypoglycaemia
- dehydration
- anaemia
- infection
- arrhythmias
- heart disease

50
Q

What examination and investigation should be done after syncope?

A
  • any physical injuries?
  • any concurrent illness?
  • neuro examination
  • lying and standing blood pressure
  • cardiac examination and ECG (potentially echocardiogram)
  • bloods - FBC, electrolytes and blood glucose
51
Q

How should syncope be managed?

A
  • exclude other pathologies
  • reassure and give simple advice
  • avoid dehydration, don’t skip meals, avoid prolonged standing
  • when experiencing prodromal symptoms, sit or lie down, have some water and something to eat and rest
52
Q

What is craniosynostosis?

A

Premature closure of the skull sutures - causing abnormal head shapes and restriction to the growth of the brain, hence raised ICP.

53
Q

What symptoms can craniosynostosis cause?

A
  • abnormal head shape that is small in proportion to the body
    Symptoms of raised ICP
  • developmental delay
  • cognitive impairment
  • vomiting
  • irritability
  • visual impairment
  • neurological symptoms
  • seizures
54
Q

How is craniosynostosis managed?

A
  • if mild = monitor and follow up over time
  • more severe = surgical reconstruction of the skull
    This has good prognosis with proper management
55
Q

What is plagiocephaly and brachycephaly?

A

Abnormal head shapes in otherwise normal healthy babies. This is very common

56
Q

What is hydrocephaly?

A

Abnormal build up of CSF within the ventricles in the brain and spinal cord.

57
Q

What are the common causes of hydrocepahlus?

A

Can be due to problems with over production, drainage or absorption.
- Aqueductal stenosis = most common - cerebral aqueduct between the 3rd and 4th ventricles is narrowed.
- arachnoid cysts
- other congenital malformations or chromosomal abnormalities

58
Q

How does hydrocephalus present?

A
  • rapidly enlarging head circumference in babies (as the sutures haven’t yet fused)
  • bulging anterior fontanelle
  • poor feeding and vomiting
  • poor tone
  • sleepiness
59
Q

How is hydrocephalus commonly managed?

A

By surgically creating a ventriculoperitoneal shunt - so that the CSF from the ventricles drains into the peritoneal cavity

60
Q

What are the complications to a ventriculoperitoneal shunt?

A
  • infection
  • can become blocked
  • excessive drainage of CSF
  • intraventricular haemorrhage during the surgery
  • child outgrows them - so need replacing about every 2 years
61
Q

What is Duchennes muscular dystrophy?

A

A X linked recessive genetic condition that causes gradual weakning and wasting of muscles. This is a defective gene for dystrophin on the X chromosome - this normally helps to hold muscles together at a cellular level

62
Q

How does Duchennes muscular dystrophy present?

A
  • Normally boys around 3-5 years.
  • weakness around their pelvis which is progessive until all muscles affected
  • Gowers sign (using a downward dog and then their legs to get up)
63
Q

What is the prognosis for Duchennes muscular dystrophy?

A
  • usually wheelchair bound by teenage years
  • life expectancy of 25-35 years - due to resp and cardiac complications
64
Q

How is Duchennes muscular dystrophy managed?

A

Supportive to ensure best quality of life
- occupational therapy
- physio - access to wheelchairs etc.
- management of any complications
Oral steroids - can slow progession slightly
Creatine supplements to slightly improve muscle strength

65
Q

What is spinal muscular atropy?

A

Rare autosomal recessive condition that causes progressive loss of lower motor neurones in the spinal cord and hence progressive muscular weakness

66
Q

What are signs of a lower motor neurone lesion?

A
  • fasciculation’s
  • hypotonia
  • hyporeflexia
  • reduced power
  • reduced muscle bulk
67
Q

How is spinal muscular atropy managed?

A
  • physiotherapy - maximising strength in muscles and retaining resp function. Access to walking aids / wheelchairs.
  • respiratory support may be needed
  • PEG feeding if unsafe swallow
68
