17
Q
Managing safegaurding concerns
A
All NHS organisations should have a safeguarding team or safeguarding lead that should be available to assist with safeguarding concerns. Once a safeguarding concern is identified the person that identifies it is responsible for escalating it to someone that can take action on it. It is generally not the role of the doctor or nurse to investigate or manage the concern, but it is their responsibility to refer or pass this on to someone trained and in a position to investigate further and take action.
Generally safeguarding cases are referred to children’s services (social services) who can investigate further and decide what action needs to be taken. Most safeguarding cases don’t involve children being removed from their parents. Usually social services are able to put in extra support and services and follow up over time. 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.
Maintaining a professional, open, honest and trusting relationship with parents or carers is important, even when they are responsible for the abuse. This will make all aspects of any investigation and management easier, and lead to better outcomes.
18
Q
What issues with breastfeeding may lead to inadequete nutrition for the neonate?
A
Poor milk supply
Difficulty latching
Discomfort or pain for the mother
19
Q
When is overfeeding more common in babies?
A
Both breast and bottle feeding can lead to overfeeding, however overfeeding is more common in bottle-fed babies.
20
Q
The world health organisation recommend exclusive breastfeeding how long?
A
for the first 6 months of life
21
Q
Benefits of breastfeeding?
A
Breast milk contains antibodies that can help protect the neonate against infection.
Breastfeeding has been linked to reduced infections in the neonatal period, better cognitive development, lower risk of certain conditions later in life and a reduced risk of sudden infant death syndrome.
Body composition appears to be slightly different between breast and bottle-fed babies and children and adolescents that were breastfed appear to have less obesity.
There is evidence that breastfeeding can reduce breast cancer and ovarian cancer risk in the mother.
22
Q
Feeding Volumes in Babies
A
On formula feed, babies should receive around 150ml of milk per kg of body weight. Preterm and underweight babies may require larger volumes. This is split between feeds every 2-3 hours initially, then to 4 hours and longer between feeds. Eventually babies and infants transition to feeding on demand (when they are hungry).
60mls/kg/day on day 1
90mls/kg/day on day 2
120mls/kg/day on day 3
150mls/kg/day on day 4 and onwards
23
Q
How much weight is it acceptable for a baby to lose in the first 5 days of life?
A
It is acceptable for breast fed babies to loose up to 10% and formula fed babies to loose up to 5% of their body weight by day 5 of life
24
Q
Most common cause excessive weight loss or not regaining weight in new borns?
A
The most common cause of excessive weight loss or not regaining weight is dehydration due to under feeding, even when they do not clinically look dehydrated. The most reliable sign of dehydration in babies is weight loss.
25
Weaning
Weaning refers to the gradual transition from milk to normal food. Weaning usually starts around 6 months of age. It starts with pureed foods that are easy to palate, swallow and digest, for example pureed fruit and “baby rice”.
Over 6 months this will progress towards a healthy diet resembling an older child, supplemented with milk and snacks to 1 year of age.
26
What is included on a child's growth chart?
Growth charts are used to plot a child’s weight, height and head circumference against the the normal distribution for their age and gender. The child’s measurements are plotted on a graph using a dot. The age is plotted on the x-axis and the weight, height and head circumference are plotted on the y-axis.
Centiles (cent– meaning hundred) indicate where a child’s growth compares to the normal distribution for their age and sex.
27
What is important to establish when there are concerns re a childs growth chart?
The important thing when assessing a child where there are concerns about not gaining weight or height is to establish whether they are maintaining their centile. If a child is on the 9th centile, but they have always been on the 9th centile, that is much less concerning than a child that was on the 91st centile and is now on the 9th.
28
What are the three phases of growth?
First 2 years: rapid growth driven by nutritional factors
From 2 years to puberty: steady slow growth
During puberty: rapid growth spurt driven by sex hormones
29
What is defined as obese/overweight in children
Overweight is defined as a body mass index (BMI) above the 85th percentile and obese as above the 95th percentile
30
Why is childhood obesity increasing?
Obesity in children results from consuming more calories than are expended through activity and growth. Recently, access to readily available, affordable, hyper-palatable, high calorie foods has lead to the overconsumption of calories. There has been a shift from physical activities and outdoor play to sedentary activities such as video games and screens. This has contributed to an increase in childhood obesity.
31
Obesity in children: height considerations
Obese children are often tall for their age and come from overweight families. If children are short and obese, consider endocrine investigations for an underlying cause, such as hypothyroidism. A pathological cause is rare.
32
Effects of obesity in children
Bullying
Increased likelihood of it continuing into adulthood
Risk later in life of:
Imapired glucose tolerance
T2DM
CVD
Arthritis
Cancer
33
What is failure to thrive?
Failure to thrive refers to poor physical growth and development in a child.
34
What is faltering growth?
Faltering growth is defined in the 2017 NICE guidelines on faltering growth in children as a fall in weight across:
- One or more centile spaces if their birthweight was below the 9th centile
- Two or more centile spaces if their birthweight was between the 9th and 91st centile
- Three or more centile spaces if their birthweight was above the 91st centile
35
What is a centile space?
Centile spaces are the distance between two centile lines on a growth chart.
The distance between the 75th and 50th centile lines is a centile space.
A weight that falls this distance is a drop across one centile space.
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.
36
Anything that leads to inadequate energy and nutrition can lead to failure to thrive. The causes can be categorised how?
Inadequate nutritional intake
Difficulty feeding
Malabsorption
Increased energy requirements
Inability to process nutrition
37
Failure to thrive: inadequate nutritional intake causes
Maternal malabsorption if breastfeeding
Iron deficiency anaemia
Family or parental problems
Neglect
Availability of food (i.e. poverty)
38

Poor suck, for example due to CP
Cleft lip or plate
Genetic conditions with an abnormal facial structure
Pyloric stenosis
39
Failure to thrive: causes of malabsorption
Cystic fibrosis
Coeliac disease
Cows milk intolerance
Chronic diarrhoea
Inflammatory bowel disease
40
Failure to thrive: causes of increased energy requirement
Hyperthyroidism
Chronic disease - e.g. congenital heart disease, CF
Malignanacy
Chronic infections e.g. HIV or immunodeficiency
41
Failure to thrive: inability to process nutrients properly
Inborn errors of metabloism
T1DM
42
Failure to thrive - key areas to assess
Pregnancy, birth, developmental and social history
Feeding or eating history
Observe feeding
Mums physical and mental health
Parent-child interactions
Height, weight and BMI (if older than 2 years) and plotting these on a growth chart
Calculate the mid-parental height centile
43
How is BMI calculated
BMI is calculated as: (weight in kg) / (height in meters)2.
44
Feeding history
A feeding history involves asking about breast or bottle feeding, feeding times, volume and frequency and any difficulties with feeding. An eating history involves asking about food choices, food aversion, meal time routines and appetite in children. Asking the parent to keep a food diary can be helpful.
45
What BMI might indicate inadequate nutrition or a growth disorder?
BMI below the 2nd centile
46
What BMI might indicate inadequate nutrition or a growth disorder?
BMI below the 2nd centile
47
What mid-parental height might indicate inadequate nutrition or a growth disorder?
Height more than 2 centile spaces below the mid-parental height centile
48
How is mid parental height calculated
Mid parental height is calculated as: (height of mum + height of dad) / 2.
49
NICE reccomendations on investigating faltering growth?
Urine dipstick, for urinary tract infection
Coeliac screen (anti-TTG or anti-EMA antibodies)
Further investigations are usually not necessary where there are no other clinical concerns. Focused investigations should be considered where additional signs or symptoms suggest an underlying diagnosis, such as cystic fibrosis or pyloric stenosis.
50
Management of failure to thrive?
Management depends on the cause and may involve input from the multidisciplinary team. All children with faltering growth should have regular reviews to monitor weight gain. Reviews that are too frequent can increase parental anxiety.
Where difficulty with breastfeeding is the cause, there are lots of ways for the mother to get support, including midwives, health visitors, peers groups and “lactation consultants”. Supplementing with formula milk is likely to successfully improve growth, however it often results in breastfeeding stopping. Mother should be encouraged to feed with breastmilk prior to top-up feeds, and express when not breastfeeding to encourage lactation to continue.
Where inadequate nutrition is the cause there are several management options based on individual circumstances:
Encouraging regular structured mealtimes and snacks
Reduce milk consumption to improve appetite for other foods
Review by a dietician
Additional energy dense foods to boost calories
Nutritional supplements drinks
Where other measures fail and there are serious concerns the multidisciplinary team may consider enteral tube feeding. This needs to have clear goals and a defined end point.
51
In paediatrics, what is short stature?
Short stature is defined as a height more than 2 standard deviations below the average for their age and sex. This is the same as being below the 2nd centile.
52
Calculating a child's predicted height?
Boys: (mother height + fathers height + 14cm) / 2
Girls: (mothers height + father height – 14cm) / 2
53
Causes of short stature (below 2nd centile) in children?
Familial short stature
Constitutional delay in growth and development
Malnutrition
Chronic diseases, such as coeliac disease, inflammatory bowel disease or congenital heart disease
Endocrine disorders, such as hypothyroidism
Genetic conditions, such as Down syndrome
Skeletal dysplasias, such as achondroplasia
54
What Is Constitutional Delay In Growth and Puberty?
Constitutional delay in growth and puberty (CDGP) is considered a variation on normal development. It leads to short stature in childhood when compared with peers but normal height in adulthood. Puberty is delayed and the growth spurt during puberty lasts longer. They ultimately reach their predicted adult height.
55
What objective feature will be present in CDGP
A key feature of CDGP is delayed bone age. It is possible to estimate the age of a child using xray images of their wrist and hand by assessing the size and shape of the bones and the growth plates. Children with CDGP will have a delayed bone age compared with the reference for their age and sex.
56
CDGP: diagnosis and management
Diagnosis is based on a suggestive history and examination and can be supported by an xray of the hand and wrist to assess bone age. Management involves excluding other causes of a short stature and delayed puberty, reassuring parents and the child and monitoring growth over time.

What is meant by learning disability?
Learning disability is a general umbrella term encompassing a range of different conditions that affect the ability of the child to develop new skills. The amount they are affected varies from mild to severe. In mild cases the child may simply need extra time and help with learning new skills. In severe cases there can be significant intellectual impairment and they may need help with all activities of daily living.
124
Learning difficulty examples
Dyslexia refers to a specific difficulty in reading, writing and spelling.
Dysgraphia refers to a specific difficulty in writing.
Dyspraxia, also known as developmental co-ordination disorder, refers to a specific type of difficulty in physical co-ordination. It is more common in boys. It presents with delayed gross and fine motor skills and a child that appears clumsy.
Auditory processing disorder refers to a specific difficulty in processing auditory information.
125
What is non-verbal learning disability?
Non-verbal learning disability refers to a specific difficulty in processing non-verbal information, such as body language and facial expressions
126
What is profound/multiple learning disability?

127
Below what IQ is considered a profound learning disability?
Under 25
128
At what IQ is a learning disability considered severe?
25-40
129
At what IQ is a learning disability considered moderate?
40-55
130
At what IQ is a learning disability considered mild?
55-70
131
Causes of learning diasbility?
Often there is no clear cause for the learning disability. A family history of learning disability increases the risk. Environmental factors such as abuse, neglect, psychological trauma and toxins can all increase the risk.
Certain conditions are strongly associated with learning disability:
Genetic disorders such as Downs syndrome
Antenatal problems, such as fetal alcohol syndrome and maternal chickenpox
Problems at birth, such as prematurity and hypoxic ischaemic encephalopathy
Problems in early childhood, such as meningitis
Autism
Epilepsy
132
Management of LD
The key to managing learning disability is with a multidisciplinary approach to support the parents and child. This involves:
Health visitors
Social workers
Schools
Educational psychologists
Paediatricians, GPs and nurses
Occupational therapists
Speech and language therapists
133
At what age does puberty start in girls?
8-14
134
At what age does puberty start in boys?
9-15 years
135
Pubertal growth spurt - boys vs girls
Earlier in girls
136
Progression of puberty in girls
In girls, puberty starts with the
development of breast buds
then pubic hair
and finally starting menstrual periods about 2 years from the start of puberty.
137
Progression of puberty in boys
In boys, puberty starts with
enlargement of the testicles,
then of the penis,
gradual darkening of the scrotum,
development of pubic hair and
deepening of the voice.
138
How long does puberty take
Around 4 years from start to finish
139
What is tanner staging used for?
The tanner scale can be used to determine the pubertal stage based on examination findings of sex characteristics.
140
What is hypogonadism?
Hypogonadism refers to a lack of the sex hormones, oestrogen and testosterone, that normally rise prior to and during puberty.
A lack of these hormones causes a delay in puberty
141
What are the two fundamental reasons hypogonadism occurs?
Hypogonadotrophic hypogonadism: a deficiency of LH and FSH
Hypergonadotrophic hypogonadism: a lack of response to LH and FSH by the gonads (the testes and ovaries)
142
Hypogonadotrophic hypogonadism
Hypogonadotropic hypogonadism is where there is a deficiency of LH and FSH, leading to a deficiency of the sex hormones testosterone and oestrogen. LH and FSH are gonadotrophins. Since there are no gonadotrophins simulating the gonads, they do not respond by producing sex hormones (testosterone and oestrogen). Therefore, you get “hypogonadism” as a result of “hypogonadotropism”.
A deficiency of LH and FSH is the result of abnormal functioning of the hypothalamus or pituitary gland.
143
Hypergonadotropic Hypogonadism
Hypergonadotropic hypogonadism is where the gonads fail to respond to stimulation from the gonadotrophins (LH and FSH). There is no negative feedback from the sex hormones (testosterone and oestrogen), therefore the anterior pituitary produces increasing amounts of LH and FSH to try harder to stimulate the gonads. Therefore, you get high gonadotrophins (“hypergonadotrophic”) and low sex hormones (“hypogonadism”).
Hypergonadotrophic hypogonadism is the result of abnormal functioning of the gonads
144
Hypogonadotrophic hypogonadism is a deficiency of LH and FSH - the result of abnormal functioning of the hypothalamus or pituitary gland. What could this be due to?
Previous damage to the hypothalamus or pituitary, for example by radiotherapy or surgery for previous cancer
Growth hormone deficiency
Hypothyroidism
Hyperprolactinaemia (high prolactin)
Serious chronic conditions can temporarily delay puberty (e.g. cystic fibrosis or inflammatory bowel disease)
Excessive exercise or dieting can delay the onset of menstruation in girls
Constitutional delay in growth and development is a temporary delay in growth and puberty without underlying physical pathology
Kallman syndrome
145
Hypergonadotrophic hypogonadism is the result of abnormal functioning of the gonads. This could be due to what?
Previous damage to the gonads (e.g. testicular torsion, cancer or infections, such as mumps)
Congenital absence of the testes or ovaries
Kleinfelter’s Syndrome (XXY)
Turner’s Syndrome (XO)
146
What type of hypogonadism does Kallman syndrome cause?
hypogonadotrophic hypogonadism
147
What is Kallman syndrome?
Kallman syndrome is a genetic condition causing hypogonadotrophic hypogonadism, resulting in failure to start puberty. It is associated with a reduced or absent sense of smell (anosmia).
148
What is the threshold for initiating investigations where there is no evidence of pubertal changes?
Age 13 in girls
Age 14 in boys
Investigation can also be considered when there is some evidence of puberty but no progression over 2 years.
149
Delayed puberty - history and examination
Detailed history of their general health, development, family history, diet and lifestyle.
An examination to assess height, weight, stage of pubertal development and features of underlying conditions.
150
Delayed puberty: investigations
Bloods for underlying medical conditions: FBC, U&Es, anti-TTG or anti-EMA
Hormonal blood tests for hormonal abnormalities: early morning serum FSH and LH, TFTs, ILGF-1, serum prolactin
Genetic testing with a microarray
Imaging: X ray of wrist, pelvic USS, MRI brain
151
What imaging may be useful in ?delayed puberty and why
Xray of the wrist to assess bone age and inform a diagnosis of constitutional delay
Pelvic ultrasound in girls to assess the ovaries and other pelvic organs
MRI of the brain to look for pituitary pathology and assess the olfactory bulbs in possible Kallman syndrome
152
Genetic testing with a microarray test can be used to look for what underlying genetic conditions when considering ?delayed puberty
Genetic testing with a microarray test can be used to look for underlying genetic conditions:
Kleinfelter’s syndrome (XXY)
Turner’s syndrome (XO)
153
What hormonal blood tests may be performed in ?delayed puberty
Early morning serum FSH and LH (the gonadotropins). These will be low in hypogonadotrophic hypogonadism and high in hypergonadotrophic hypogonadism.
Thyroid function tests
Growth hormone testing. Insulin-like growth factor I is often used as a screening test for GH deficiency.
Serum prolactin
154
What bloods may be done to look for underlying medical conditions in ?delayed puberty and why
Full blood count and ferritin for anaemia
U&E for chronic kidney disease
Anti-TTG or anti-EMA antibodies for coeliac disease
155
Management of delayed puberty
Management involves treating the underling condition where there is one. Patients with constitutional delay may only require reassurance and observation. Replacement sex hormones (oestrogen in girls and testosterone in boys) can be used to induce puberty under expert guidance.
156
Karyotype in turners syndrome?
Turner’s syndrome (XO)
157
Karyotype in Kleinfelter’s syndrome
Kleinfelter’s syndrome (XXY)
158
What type of hypogonadism are Kleinfelter’s Syndrome (XXY) and Turner’s Syndrome (XO), and what will be seen on bloods?
Hypergonadotropic hypogonadism- gonads fail to respond to stimulation from the gonadotrophins (LH and FSH).
There is no negative feedback from the sex hormones (testosterone and oestrogen), therefore the anterior pituitary produces increasing amounts of LH and FSH to try harder to stimulate the gonads.
Therefore, you get high gonadotrophins (“hypergonadotrophic”) and low sex hormones (“hypogonadism”) - LOW FSH AND LH

When considering consent to treatment, how do 18 year olds, 16-17 year olds and under 16s differ?
A person is recognised as an adult with full autonomy to make decisions about their health when they turn 18.
16 and 17 year olds can also make independent decisions about their health, but if they refuse treatment this can be overruled in certain situations by parents, people with parental responsibility or the court.
Children under 16 can make decisions about treatment, but only if they are deemed to have Gillick competence. There is no lower limit to the age where children can make decisions about their health, however it is unusual for consent to be taken from someone under 13.
160
What is Gillick competence?
Gillick competence refers to a judgement about the whether the understanding and intelligence of the child is sufficient to consent to treatment.
Gillick competence needs to be assessed on a decision by decision basis, checking whether the child understands the implications of the treatment.
Consent needs to be given voluntarily.
When prescribing contraception to children under 16 it is important to assess for coercion or pressure, for example coercion by an older partner. This might raise safeguarding concerns.
161
Criteria for Frazer guidlines?
They are mature and intelligent enough to understand the treatment
They can’t be persuaded to discuss it with their parents or let the health professional discuss it
They are likely to have intercourse regardless of treatment
Their physical or mental health is likely to suffer without treatment
Treatment is in their best interest
162
Confidentiality and Frazer guidlines
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.
163
What are the Frazer guidelines for?
Frazer guidelines are specific guidelines for providing contraception to patients under 16 years without having parental input and consent.
164
Under what age does a child participating in sexual activity warrant immediate safegaurding referal?
Children under 13 cannot give consent for sexual activity. All intercourse in children under 13 years should be escalated as a safeguarding concern to a senior or designated child protection doctor.
165
Contraception in under 16s - breaking confidentiality
Where the child is not deemed to be Gillick competent and the child is at risk of harm, this should be escalated as a safeguarding concern.
Children under 13 cannot give consent for sexual activity. All intercourse in children under 13 years should be escalated as a safeguarding concern to a senior or designated child protection doctor.
166
What hormone is responsble for growth spurts in the begining of puberty?
GnRH
167
In children whom conservative measures including a reward system and enuresis alarm fail to control nocturnal enuresis, drug treatment may be trialed in children over 7 years of age. The first line choice is what, and for how long is it given?
Desmopressin, a synthetic replacement for antidiuretic hormone.
Treatment should be assessed after one month and continued for three months if there are signs of response
168
At what age would the average child start to smile?
6 weeks
169
GDPP vs GIPP
In gonadotrophin dependent precocious puberty (GDPP), or 'central' precocious puberty, the levels of the gonadotrophins LH and FSH would be high and testes would be large for age.
In GIPP symptoms are caused by increased levels of sex hormones, for example, testosterone, leading to the suppression of LH and FSH. Increased sex hormone secretion may be due to ovarian, testicular or adrenal causes like congenital adrenal hyperplasia. In boys, the testicular volume will tend to be normal or small.
170
At what age would the average child start to say 'mama' and 'dada'?
