Q

What are the feeding volumes in babies?

A

Titrated up across the first week of life as tolerated, to target of 150ml/kg/day.

This is initially split between feeds every 2-3 hours, then to 4 hours and longer.

Eventually babies transition to feeding on demand.

Q

What is the acceptable rate of initial weight loss in babies?

A

Lose up to 10% of body weight in the first 5 days.

However, they should regain their birth weight by day 10.

Q

What is the most common cause of excessive initial weight loss in babies?

A

Dehydration due to under feeding.

The most reliable sign of dehydration in babies is weight loss - even when they do not clinically look dehydrated.

Q

When does weaning begin?

A

At around 6 months of age, babies are gradually transitioned from milk to normal food.

It starts with pureed foods that are easy to palate, and gradually progresses towards a healthy diet resembling an older child.

Until the age of 1 year, this can be supplemented with milk and snacks.

Q

What factors have contributed towards an increase in childhood obesity?

A

Increased access to readily available, affordable, high calorie foods. This leads to the overconsumption of calories.

There has also been a shift from physical activities and outdoor play, to sedentary activities such as video games and screens.

NICE (2017) definitions of failure to thrive.

A

Fall in weight across:
- one or more centile spaces if birthweight was below the 9th centile
- two or more centile spaces if their birthweight was between the 9th and 91st centile

A

The distance between two centile lines.

For example, if the initial weight of a child is plotted halfway between the 9th and 25th centile lines, and several months later is plotted halfway between the 2nd and 9th centile lines, they have dropped a full centile space.

A

4 years from start to finish.

61

a) girls

b) boys

A

a) development of breast buds

b) enlargement of the testicles

62
Q

How is puberty staged?

A

Tanner scale

63
Q

What is hypogonadism?

A

A lack of the sex hormones, oestrogen and testosterone.

64
Q

What is the consequence of hypogonadism?

A

Delayed puberty.

65
Q

What are the causes of hypogonadism?

A

Hypogonadotrophic hypogonadism: a deficiency in LH and FSH.

Hypergonadotrophic hypogonadism: a lack of response to LH and FSH by the gonads.

66
Q

What is hypogonadotrophic hypogonadism?

A

A deficiency in LH and FSH, leading to a deficiency of testosterone and oestrogen.

This is the result of an abnormal functioning of the hypothalamus or pituitary gland.

67
Q

Causes of hypogonadotrophic hypogonadism.

A

A deficiency of LH and FSH as a result of abnormal functioning of the hypothalamus or pituitary gland:
- damage to the hypothalamus or pituitary
- growth hormone deficiency
- hypothyroidism
- hyperprolactinaemia
- cystic fibrosis
- excessive exercise or dieting
- constitutional delay in growth
- Kallman syndrome

68
Q

What is hypergonadotrophic hypogonadism.

A

The gonads fail to respond to stimulation from LH and FSH.

Therefore, there is no negative feedback from testosterone and oestrogen, so the anterior pituitary produces increasing amounts of LH and FSH.

69
Q

Causes of hypergonadotrophic hypogonadism.

A

Abnormal functioning of the gonads:
- damage to the gonads (e.g. testicular torsion, cancer, mumps)
- congenital absence of gonads
- Kleinfelter’s syndrome (XXY)
- Turner’s syndrome (XO)

70
Q

What is Kallman syndrome?

A

A genetic condition causing hypogonadotrophic hypogonadism.

Results in a failure to start puberty, and a reduced or absent sense of smell.

71
Q

What is the threshold for initiating investigations for delayed puberty?

A

No evidence of pubertal changes in a girl aged 13, or a boy aged 14.

72
Q

Initial investigations for delayed puberty.

A
  • FBC and ferritin (?anaemia)
  • U&Es (?CKD)
  • anti-TTG / anti-EMA (?coeliac)
73
Q

Hormonal blood tests for delayed puberty.

A
  • early morning serum FSH and LH
  • TFTs (?hypothyroidism)
  • growth hormone testing
  • serum prolactin (?hyperprolactinaemia)
74
Q

What genetic conditions are often screened for in delayed puberty?

A
  • Kleinfelter’s sydrome (XXY)
  • Turner’s syndrome (XO)
75
Q

What imaging is requested for delayed puberty?

A
  • xray of wrist to assess bone age (?constitutional delay)
  • pelvic ultrasound in girls to assess the ovaries
  • MRI brain (?pituitary pathology; ?Kallman syndrome)
76
Q

Management of delayed puberty.

A

Identifying and treating the underlying condition where there is one.

Patients with constitutional delay may only require reassurance and observation.

Under expert guidance, replacement sex hormones can be used to induce puberty.

77
Q

What are the types of abuse?

A
  • physical
  • emotional
  • sexual
  • neglect
  • financial
  • idenity
78
Q

Risk factors for abuse.

A
  • domestic violence
  • previously abused parent
  • mental health problems
  • disability in the child
  • learning disability in parents
  • substance misuse
  • non-engagement with services
79
Q

Possible signs of abuse in children.

A
  • change in behaviour
  • extreme emotional states
  • dissociative disorders
  • bullying
  • DSH / suicidal ideation
  • sexualised behaviour
  • poor hygiene
  • developmental delay
  • medical non-compliance
80
Q

How should a safeguarding concern be managed?

A

Refer to safeguarding team or safeguarding lead, to discuss referral to social services.

Most safeguarding cases don’t involve children being removed from their parents, and instead focus on providing extra support and services.

81
Q

What measures can be arranged by social services to support families of children with safeguarding concerns?

A
  • home visit programmes to support parents
  • parenting programmes
  • attachment-based interventions to help parents bond
  • child-parent psychotherapy
  • cognitive behavioural therapy for children that have suffered trauma or sexual abuse

NB: if the child is in immediate danger the police may need to be involved; if they are acutely unwell or need a place of safety they should be admitted to hospital.

82
Q

When is a person recognised as an adult with full autonomy to make decisions about their health?

A

Aged 18.

16 or 17 year olds can make independent decisions about their health, but if they refuse treatment this can be overruled by people with parental responsibility (or the court) in certain situations.

83
Q

How are children aged under 16 assessed to have capacity to make a decision?

A

Gillick competence - refers to a judgement about whether the understanding and intelligence of a child is sufficient to consent to treatment.

Consent must be given voluntarily, and it’s important to assess for coercion or pressure.

84
Q

What are the Frazer guidelines used for?

A

Providing contraception to patients under 16 years without having parental input and consent.

85
Q

What are the criteria of the Frazer guidelines?

A
  • mature and intelligent enough to understand the treatment
  • can’t be persuaded to discuss it with their parents, or let the health professional discuss it
  • likely to have intercourse regardless of treatment
  • physical or mental health likely to suffer without treatment
  • treatment is in best interest

Children should be encouraged to inform their parents, but if they decline and meet the criteria for Gillick competence and the Frazer guidelines confidentiality can be kept.

86
Q

At what age should sexual activity raise a safeguarding concern?

A

Children under 13 cannot give consent for sexual activity, so should be escalated as a safeguarding concern.

87
Q

What is the age of sexual consent in England and Wales?

A

16 years - however children under the age of 13 are seen as being less capable of consenting than those aged 13 and over.
